Description

Technical Field

[0001] The utility model relates to a pretreatment device, in particular to a rubber processing pretreatment device, belonging to the technical field of rubber processing. Background Art

[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 large molecular weight, greater than hundreds of thousands. Rubber products are widely used in various aspects of industry and life. However, in rubber production, the rubber raw materials need to be crushed, then melted and injected into the mold to form the rubber.

[0003] Traditional crushers are not convenient for classifying the crushed materials. When there is uneven crushing, it affects subsequent processing. The filter screen inside the crusher lacks a shaking component, which makes the material discharge slowly after crushing, which easily causes the filter screen to be blocked. Moreover, when the material is discharged slowly, if too much material accumulates in the crusher, it is easy to cause the equipment to jam. Utility Model Content
