Description

Technical Field

[0001] The present application relates to the technical field of rubber and plastic strip cutting applications, and in particular to an auxiliary device for impact-resistant rubber and plastic strip cutting. Background Art

[0002] Rubber and plastic strips refer to strip products made of rubber and plastic. Rubber and plastic are the general names for the rubber and plastic industries. They are all by-products of petroleum. They are the same in source, but in the process of making products, their physical properties are different, and their uses are even more different. The most widely used rubber is tires, and plastics are becoming more and more widely used with the demand of technology and market. The most essential difference between plastic and rubber is that plastic deformation occurs when plastic is deformed, while rubber is elastic deformation.

[0003] Plastic and rubber are both polymer materials. When cutting rubber and plastic materials into strips, due to production requirements, plastic film needs to be pasted on the rubber and plastic strips to prevent dust and stickiness. In order to ensure the integrity of the product, the rubber and plastic strips need to be cut and the plastic film needs to be connected together. However, it is difficult to ensure cutting accuracy during the strip cutting process, and it is easy to cut the rubber and plastic strips and the plastic film at the same time and fail to meet production requirements. Frequent cutting will cause the blade to heat up due to friction, and the temperature generated by the blade will affect the pixel product and the plastic film, reducing the production quality of the rubber and plastic strips.
