High-angle conveyor belt, advantages and improvements
The high-angle corrugated sidewall belt consists of three parts: base belt, sidewall and transverse partition. The sidewall prevents the material from slipping and scattering. In order to facilitate bypassing the roller, the sidewall is designed to be corrugated; the function of the transverse partition is to support the material. In order to achieve high-angle conveying, T-type TC type is adopted. The sidewall and transverse partition are connected to the base belt by secondary vulcanization, and have a high connection strength. The sidewall prevents the material from slipping and scattering.

The sidewall and transverse partition are connected to the base belt by secondary vulcanization, and have a high connection strength. Corrugated sidewall conveyor belt (ordinary high-angle corrugated sidewall conveyor belt) Varieties: According to the different properties of the covering rubber, it can be divided into ordinary type, heat-resistant type, flame-retardant type, cold-resistant type, acid-alkali resistant type, oil-resistant type, etc.
Optimization and improvement of sidewall conveyor belts In order to improve the bearing capacity of the sidewall conveyor belt, the transverse bending deformation of the sidewall conveyor belt after loading is quite small, that is, improving the transverse rigidity of the sidewall conveyor belt is the key to reducing the transverse bearing deformation of the belt and increasing the bearing capacity of the belt.
The transverse rigidity value of the sidewall conveyor belt refers to the ratio of the weight of the belt under bending caused by the deadweight of the sidewall conveyor belt on both sides of the free support belt in the transverse vertical section of the belt to the width of the belt. The technical standard requirement for the transverse rigidity value of the sidewall conveyor belt with high transverse rigidity is not more than 0.05. After optimizing and improving the structure of the sidewall conveyor belt, the transverse rigidity detection value is 0.036 after adding the transverse rigidity reinforcement layer. The transverse deformation of the belt after loading is reduced, which can increase the bearing capacity by 15% to 20%. An effective measure to improve the transverse rigidity of large heavy-duty sidewall conveyor belts is to set a polyester short fiber composite rubber layer that has been specially mixed and calendered between the multi-layer tensile body canvas layers of the flat base belt body, that is, a rubber layer in which polyester short fibers are arranged and buried in a single transverse direction of the belt body.
The use of this composite rubber layer that enhances the transverse bending resistance of the sidewall conveyor belt body can increase the transverse rigidity of the belt body by 2.5 times compared with the sidewall conveyor belt of ordinary structure, that is, its transverse rigidity value is increased from 0.09 to 0.036.
