[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in various aspects of industry or life. The rubber material extrusion process is the process of making rubber products. Rubber strips are a common rubber material product. In the production process of rubber strips, rubber material extrusion equipment is often required to extrude the rubber strips to form rubber strips.

[0004] However, the mobile rubber extrusion device provided in the above technical solution still has many disadvantages in actual use. For example, the structure of the rubber discharging component is fixed, so different discharging components need to be replaced when extruding rubber strips of different sizes, and there is no cooling mechanism on the outside of the discharging component, so that the rubber product cannot be immediately cooled and formed when the rubber material is extruded, and the discharging material is prone to deformation, thereby affecting the quality of the extrusion molding of the rubber material.
