Pattern conveyor belt Pattern conveyor belt is composed of base belt and pattern. Due to different materials to be transported and different conveying inclination angles, the pattern shapes and heights are also required. Commonly used pattern conveyor belt varieties include: herringbone pattern conveyor belt, figure eight pattern conveyor belt, herringbone pattern conveyor belt, U-shaped pattern conveyor belt, cylindrical pattern conveyor belt, pitted pattern conveyor belt, etc. Or designed according to user requirements, suitable for conveying powdery, granular, and block materials with an inclination angle of less than 30 degrees. Commonly used types of pattern conveyor belts are as follows: 1. Characteristics of herringbone pattern: There is a "herringbone" pattern on the belt surface that is higher than the belt body. The pattern can be open or closed. Each pattern can be divided into high, There are three types: medium and low. Purpose: Suitable for conveying powdery, granular and small materials with an inclination angle of ≤40 degrees, and can also convey bagged materials. 2. Striped pattern features: There are striped patterns on the surface of the belt that are higher than the belt body. The patterns are divided into three types: high, medium and low. Each pattern can be divided into sparse and dense forms according to the arrangement spacing. Purpose: Suitable for horizontal transportation of packages with an inclination angle of ≤30 degrees. If it is grooved, it can be replaced by a herringbone pattern. 3. Grainy Pattern Characteristics: There are grainy patterns on the belt surface that are higher than the belt body or recessed into the belt body. The pits can also be made into square holes, prisms and cloth patterns. Purpose: The convex grain pattern is suitable for soft packaging or material conveying that requires grip (such as cardboard boxes) or non-slip conveying. The pit-shaped granular pattern is suitable for conveying granular materials with an inclination angle of ≤45 degrees. 4. Fan-shaped pattern Features: There is a semi-fan-shaped (or 1/4-circle) pattern on the belt surface. When the tape is grooved, the pattern merges into a fan shape (or semicircle), which is a high pattern type. Purpose: Suitable for conveying powder, granular and block materials at a large inclination angle of ≤60 degrees. Our company can supply patterned conveyor belts with a width of ≤2400mm.

Base belt of large-angle sidewall conveyor belt: The skeleton material is made of polyester-cotton dipped canvas (EP canvas, steel rope core) and a transverse rigid reinforcement layer; a transverse rigidity reinforcement layer is added to the belt body to solve the problem of large-sized sidewall conveyor belts. Collapse problem. Sidewall: According to the function of the sidewall and the operating characteristics of the overall belt, measures such as increasing the glue content of the sidewall and adding nylon cloth as a skeleton layer inside the sidewall have been adopted to enhance the flexural and tear resistance of the sidewall. crack resistance, which improves the service life of the ribs. Partition: The mixing process of rubber and fiber composite materials makes the partition stiff and hard, enhances impact resistance, and avoids the occurrence of cracks due to large forces. deformation. Bonding of base tape, ribs and partitions: The advanced process of secondary simultaneous low-temperature continuous vulcanization is adopted to improve the bonding strength and avoid aging of the base tape due to multiple high-temperature vulcanizations. Bolt connection technology is used between the ribs and partitions, which not only solves the problem of material leakage caused by lifting materials at a large angle, but also improves the rigidity of the belt body. Features of high-incline sidewall conveyor belts: Suitable for conveying bulk materials with an inclination angle of 0° to 90°; it has the characteristics of wide range of use, small footprint, no transfer points, reduced civil construction investment, low maintenance costs, and large transportation capacity; solve It achieves a conveying angle that cannot be achieved by ordinary belts and patterned belts; it can also be designed into a complete and independent conveying system according to the use environment, avoiding intermittent conveying and complex conveying lifting systems.
