In order to improve the load-bearing capacity of the belt body, the lateral bending deformation of the belt body is the minimum after loading, that is, improving the lateral rigidity of the belt body is the key to reduce the lateral bearing deformation and increase the load-bearing capacity of the belt body.
The transverse rigidity value of the belt body of the edge conveyor belt refers to the ratio of the bending weight of the belt body and the width of the belt body caused by the dead weight of the belt body of the edge conveyor belt, which freely supports the two sides of the belt body in the transverse vertical section of the belt body. The technical standard requirement of the lateral rigidity value of the high lateral rigidity edge conveyor belt is not more than 0.05. Through the optimization and improvement of the structure of the edge conveyor belt, the lateral rigidity detection value is 0.036 after adding the lateral rigidity reinforcement layer, the lateral deformation of the belt body is reduced after loading, and the bearing capacity can be increased by 15% ~ 20%.
The effective measure to improve the transverse rigidity of large heavy duty side belt is to set a special composite adhesive layer of polyester staple fiber through special mixing and calendering between the layers of multi-layer tensile body canvas of flat base body, that is, the adhesive layer of polyester staple fiber buried along the transverse direction of belt body in the adhesive layer.
The use of the special composite adhesive layer which can enhance the lateral bending resistance of the belt body of the edge conveyor belt can increase the lateral rigidity of the belt body by 2.5 times compared with that of the ordinary edge conveyor belt, even if the lateral rigidity of the belt body is increased from 0.09 to 0.036.
These are the improvement of the formula of the side conveyor belt. What can really improve the service life of the conveyor belt lies in the use of the conveyor belt by the operator. Unprofessional operation will greatly consume the service life of the conveyor belt.
