1. Indicator lights 1. Red light: Turn off the car after acetylene. Treatment method: Find the broken head and press it to drive directly. 2. Green light: cut off the weft and shut down the vehicle. (Pay attention to the dense road) Self-care method: plain weave: just pull up the support head, press the inching switch after handling the broken weft, send the sword to send a weft yarn into the shed, pull out the broken weft, and put the support head , drive directly, twill or jacquard, pull up the support head, slide the pattern paper backward (counterclockwise) through 2 grids, and then handle the broken weft. After punching out the loose thread, put the weft yarn into the shed to make up one weft, put down the support clamp and start the machine directly. 3. Yellow light: drive due to lack of weft yarn. Treatment method: Connect the weft yarn or clean the floral pattern inside the tension tile of the weft feeder, press the stop button on the electric control box and then press the start switch to start the machine. 4. White light: The electrical box fails and shuts down the vehicle due to self-protection. Self-care method: Turn off the power supply of the electrical box for 10 seconds and then turn it on again. After the white light goes out, drive directly. If it still comes on, turn off the car and call an electrician for repair. 2. Common electrical faults and troubleshooting methods: A. Weft feeder 1. The weft feeder does not work. a) Check whether the fuse is intact and whether the intermediate relay is damaged. b) Check whether the wiring of leads 4 (9), 5 (10), and 6 (11) has fallen off. 2. The yarn of the weft feeder is broken but the machine is not turned off. a) Check whether the wiring between leads 7 and 8 and between leads 12 and 13 is disconnected. b) Whether the position between the sensor and the pattern plate is correct, whether the sensor is damaged, and whether the sensor leads (19, 20, 21, 22, 23) fall off. 3. The weft feeder keeps filling but stops. Check for a short between leads 7 and 8 (125B). B. Warp stop 1. The warp is broken but does not stop. a) Check whether leads 17 and 18 have fallen off. b) Check whether the position between the sensor and the sending plate is correct, whether the sensor lead has fallen off, and whether the sensor is damaged. 2. The warp continues but stops a) Check whether there is a short circuit between leads 7 and 8 (or the wires are connected reversely). b) Is the warp stop frame insulated? c. Weft stop 1. Do not stop when the weft is broken. a) Check whether the weft detector is damaged and whether the sensitivity is too low. b) Check whether the return dial K on the computer board is dialed up. c) If letter 1, letter 2, and letter 3 are not lit, check whether the leads and the 5V output are off-line, and whether the sensor is damaged. d) Check whether the position of the sensor and the instrument panel is correct. 2. The weft yarn stops continuously. a) Check whether the sensitivity of the weft detector is too high and whether the weft detector is damaged. b) Check whether one of the sensors (Hall element) is damaged. c) Check for short circuit between sensor leads (22, 23). Remarks: Angle of transmitter seat and sensor: Angle 0° 115° 180° 250° 295° Letter 1√√√×× Letter 2√××√√ Letter 3√√×√× (√ light is on, × is not light) D , the white light is on 1. Check whether there is a short circuit between the clutch and brake leads. 2. Check whether the clutch and brake are leaking electricity. 3. Discovery and elimination of common weaving faults. A1 shuts down after warp break (1) Check whether the guide rail piece is fluffy. (2) Check the sword belt and sword head to see if there are any lint or sharp edges. (3) Check the level of warp yarns a) Whether the sword head and sword belt rub the upper and lower warp yarns. b) Whether the warp thread collides with the reed seat (when the axis is dead center after bending at 180°) (4) Check the warp stop device, whether the two places of the swing arm collide, and whether the spring is relaxed. B1 cuts the weft and shuts down the machine. (1) Check the weft feeder Whether there is missing weft, correct the number of turns of the weft yarn on the weft feeder. (2) Check whether the holding force of the sword head is moderate. (3) Check whether the sword advance time of the sword head and the scissoring time of the weft shear are well coordinated. The sword entry time is 70°~75° when entering the first yarn on the weave edge. (4) Check whether the sword retracting time and the flat shedding time cooperate well (the sword retracting time and the flat shedding time are consistent, both 295°~320°, and the sword head must be retracted to the first warp of the tissue edge at the corresponding angle) ( 5) Check whether the tension of the weft tension piece is moderate. (6) Whether the fall time of the color selection box is too late or too high, and when the let-off sword head reaches the weft yarn, whether the weft yarn is above the sword head and cannot enter the jaws. If there is such a problem, you should adjust the height of the weft selection rod, turn the loom to the yarn clamping position, and check whether the yarn clamping position is correct. (7) Check whether the weft feeding sword head is deformed and whether the head is tilted. (8) Check whether the sword belt is severely worn, causing the gap between the sword belt and the guide rail to be too large, causing the sword belt to move unstable and jump up and down. (9) Check the yarn elasticity of the rapier head to see if it is insufficient or improperly adjusted. Check whether the weft yarn has slipped out of the jaws after the rapier head enters the shed. (Rotate the loom until the weft feed rapier head just enters the fabric opening, check whether there is any debris in the jaws, and pull the weft yarn by hand) If it is easy to fall off, the clamping force of the jaws should be adjusted. (10) Check whether the cutting time of the weft yarn scissors is too early (generally between 75° and 80°). The weft yarn has been cut before it completely enters the weft feeding rapier jaws, which reduces the tension of the weft yarn from the jaws. slip. (11) Check whether the weft yarn is incorrectly connected due to too small tension. (12) Check whether the handover of sending and receiving the sword is good. Turn the loom to the 180 position. Check that the sword head is in the correct position and push the sword belt with your hand to check its movement. (13) Check whether the rapier head jumps when connecting on both sides due to unevenness of the guide rail. (14) Check whether the sword wheel and sword belt holes are seriously worn. The position of the sword head is unstable and the handover is poor.
(15) Check whether the weft yarn slips from the jaws before being pulled into the shed due to wear of the jaws. (16) Check whether the opening time of the clamp opener is too late or the tail of the weft sword is too long. When the weft is caused again, the weft clamping spring pliers will pull the weft off. The reason is that there may be weft left in the jaws of the weft sword. , when inserting the weft again, the new yarn end cannot always be clamped firmly and slip off. (17) The reasons for half-width or full-width double weft on the cloth are: 1. The scissors are not sharp, causing the weft to break. 2. The weft yarn feeding clamp is too tight or the weft yarn is clamped too far in the yarn clamping spring, and the weft connecting sword cannot exceed the weft yarn, causing handover errors. 3. The timing of the scissors is wrong, and the weft yarn is pulled into the yarn opening by the weft sword. Generally, after the scissors are sharpened, they should be removed for grinding or replaced with new blades. (18) Check whether the weft sword belt and the weft sword belt are worn or loose. Whether the handover error is caused by vibration while driving. If the wear is severe, the sword head may be damaged (usually the sword belt and guide rail piece are easy to wear, and the entrance and exit of the weft feeding sword wear the fastest). (19) Check whether the weft-joining sword is low. The correction method for this phenomenon is to correct it by placing paper on the front section of the weft-joining sword head. (20) Check whether the bakelite board and sword belt on the sword head are worn. If the two sword belts are worn but can continue to be used, replace them with a new sword belt and sword head bakelite board to reduce the accumulation of errors. (21) Check whether the movements of the two swords at the handover time are consistent. If they are inconsistent, correct the 0 gear. (22) Check whether the eccentric is loose. The method is: pull the transmission belt pulley hard and observe the looseness of the eccentric wheel. (23) Check whether there is an extra section of weft yarn (about 15mm~250mm) in the normal weave near the right yarn. The root cause is: the referenced weft yarn length exceeds the set length. The tail weft yarn at the right side of the fabric is too long, and when the weft is connected Bring the weft yarn into the shed next time. The reasonable weft yarn length is about 20mm. The reasons for the excessively long weft yarn tail are: 1. The weft insertion tension is too small, making the set length too long. Cutting too late. 3. The blade of the sharp knife is not sharp. 4. The release time is too late. Check whether there is a shortage of weft yarn in the tissue near the right side of the fabric. The reasons for this weaving defect are: 1. Excessive weft tension. , after the weft connecting sword releases the weft yarn at the right side of the fabric, the weft yarn rebounds under the elastic recovery effect, causing the weft yarn to be short of a section. 2. The release cam on the right side is installed too far, causing the release time to be too early. The cutting time is too early. C. Several reasons for side-breaking stop: 1. The rapier head is worn. 2. The side brace thorn ring is not installed properly. 3. The edge heddle is too squeezed. 4. The opening time is too late. , the weaving parameters should be adjusted according to the variety. 5. The hanging heddle is too high. 6. The tension of the twisted edge and warp is uneven. D. Several reasons for the poor tension of the twisted edge. The spring tension clamp of the hemming pagoda is loose. 2. The magnet of the eight-shaped slider inside the hemming machine is too small. 3. The upper and lower hemming needles of the hemming machine are not inserted well (the hemming is generally in the plain weave position, and the upper and lower heddles are not inserted properly. There is one hemming yarn on the left and right sides of the hemming needle during the hedging movement.) E. Reasons for abnormal sound of the heald frame: 1. The heald frame clearance is poor and the heald span is bent. 2. The heald straight bar bends and rubs against the heald frame, causing the heald frames to become separated. The plate is fragile and the screws are loose. 3. The return heald box is defective. F. Causes of inaccurate parking: 1. There is oil on the two friction surfaces. G. Causes of yarn hooking: 1. The support plate is low. 2. The heddle distance is too late. 4. The right waste edge is not tightened and the waste edge is too small. 5. The weft sword is drawn out too early. , Sometimes the warp yarn cannot complete the flat heddle when the process requires flat heddling. H. The root cause of cloud weaving: poor use of winding and let-off, unclear weft yarn, and the selection of healds and steel reeds also has a direct impact. The weaving process is wrong. I. The expansion force of the double weft yarn is small, poor weft supply and damage to the weft selection cardboard can produce double weft. J. The weft shrinkage capacity is improper, the opening is too late, and the weft yarn releaser is worn, which may cause the weft shrinkage phenomenon. K. There is wire residue in the defective copper thorn ring of the side brace, and the rotation is not flexible. The side brace cover and the copper thorn ring are not centered, and the tip of the side brace thorn needle touches the curved hook yarn. To the weft yarn. 4. Weft insertion 1. The time for feeding the weft sword and inserting the weft sword into the first edge yarn is 70°~75°. Generally speaking, the time for weft sword insertion and shedding is about the same. If the weft yarn is inserted too early, it will be cut. The warp yarns are pinched off, resulting in segmented weft breakage at the edge of the fabric. If it is too late, the weft shrinkage will occur. In some varieties, the tail yarns must be clamped by the warp yarns. 2. Pay attention to the principle that if the sword enters early, it will come out late. If it is too late, it will be too early to draw the sword. 3. The central handover time of the weft sword and the weft receiving sword is 180°. The distance between the weft sword head and the first track piece is about 110mm~115mm. The distance between the two sword heads is preferably 60mm~70mm. The clearance between various gears should be small. Excessive stroke can easily damage the sword head. 4. The whole process of weft insertion is as follows: the weft yarn is passed through the weft yarn detector, the tension plate, the weft yarn detector, the color selection rod, the weft feeding sword, and the weft yarn scissors, and then is led to the central handover, and the weft connecting sword takes the weft yarn. Take out the selvedge, release the cam, and the entire weft insertion process is completed. The main function of the weft feeder is to make the weft winding tension uniform and deliver a certain amount of yarn during normal operation. The main use of tension is to make the weft yarn have a certain tension. If the tension of the weft yarn is too small, the waste edge yarn tail will grow, and even relax to the extent that the weft yarn is brought into the fabric felling, forming a double weft.
If the capacity is too large, the waste edge will not be able to clamp the weft yarn, causing shrinkage and missing weft at the edge of the cloth. 5. Machine process parameters: 1. Back beam plain weave height 70mm, twill weave 110mm~120mm, dobby 90mm~110mm 2. Drop frame flat lay height 65mm, twill weave 40mm, dobby 30mm~40mm 3. Temple stays: reed width + 60mm, warp width 20mm larger than the reed width. Different types of fabrics should use different heald eyelets, which is good for the opening. Different varieties have different requirements for stop warp piece weight. If the total number of warp roots is large, it is recommended to increase the number of heald frames, which can effectively prevent the rate of broken menstruation. Precautions when using the machine: 1. The distance between the reed and the weft scissors must be 1mm to 2mm. This benchmark must be set. If the distance is greater than this distance, the weft will not enter the scissors, causing weft breakage and waste of weft. If the distance is smaller than this distance, the reed and scissors will collide. , In addition, the steel strips under the reed should be padded well. 2. It is best to tighten the screws by one person to the end. If two people tighten them, they must separate from the center and tighten to both sides at the same time. 3. One person should tie knots on the machine, and the warp tension should be even and there should be less breakage. 4. Check the warp beam teeth and tighten the screws sufficiently. 5. Menopause tablets cannot be messed up and must be flexible. 6. After weaving a section of fabric, cut off the knots of the warp yarns so that they can pass through the guide roller smoothly. 7. Check the tension of the waste edge yarn and the tension of the twisted edge yarn. 8. When loading the machine, adjust the winding weft density teeth and check whether the winding support teeth are too slippery. 9. Check the fabric surface every time you weave one meter of fabric. Don't let bad fabrics continue to be woven. At the same time, you can promptly find out the length of the waste yarn, the length of the raw edges of the cloth, and whether the twisted edges are in good condition. 6. Getting on the machine again after getting off the machine 1. Getting on the machine after getting off the machine is actually a maintenance. First of all, the whole machine must be cleaned, and all major parts of the whole machine should be fully refueled, especially the places that cannot be added during work. It is also necessary to check the tightening degree of the screws throughout the machine to check whether some specifications are out of shape and whether the various gaps have changed. 2. When changing varieties, the position of the temple and the time of entering and exiting the sword should be adjusted according to different reed widths. Special attention should be paid to the coordination of the opening and the time of entering and exiting the sword. 3. Taking type 180 as an example, when the reed width is 1700mm, the weft scissors should be placed on the third gear of the track piece. When the reed width is 1600mm, the scissors should be placed on the fourth and fifth gears of the track piece. When the reed width is about 1500mm, the scissors should be placed on the sixth gear of the track piece. 7. Maintenance: 1. After the new sword transfer box has been in operation for 3 months, it must be disassembled and inspected. The gear clearance must be adjusted. The adjustment method is as follows: Remove the thin copper sheet from the seam, adjust it so that The rotation must be flexible, and the oil must be changed at the same time, because during this running time, the new gear will have powder during operation, which will be ground together with the semi-fluid oil dirt, directly damaging the gear itself. Cleaning with diesel and reassembling can extend the life of the machine parts. To extend the service life, the angle of the gear must also be changed. Generally, the angle of the gear must be changed once every 3 months or 4 times a year. This can greatly extend the service life of the machine parts. 2. Scissors, edge shears, and edge twisters need to be maintained regularly. Always check whether the bearings inside the small eccentric are short of oil, whether the eccentric shaft under the sector plate is missing oil, and whether the copper sleeve in the large belt pulley is short of oil. Precautions for the operator to operate: 1. How to deal with broken warp yarns. The main reason is that the warp yarn at the temple is easy to break, that is, the warp yarn is broken at the temple. The warp threaded from the steel reed must not be placed into the temple cover. Due to the angle, the yarn cannot be weaved. The correct way to deal with it is to pierce the warp yarns in a vertical direction or at several adjacent warp yarns, and then put them in the temple cover. The interrupted warp yarns can be solved by simply pulling them or hanging them with a tool. 2. How to deal with broken weft yarn. a) Pull out two weft yarns first; b) Turn the winding support head over so that the winding does not work during beat-up. c) Pour two pieces of plaid paper or two pieces of pattern board; d) Use one weft drive to find out the loose yarn, put in two weft yarns, make up one weft, put down the winding support head and start the switch.
