Description

Technical Field

[0001] This utility model relates to the technical field of synthetic rubber post-processing equipment, specifically to a rubber crusher with a pusher screw. Background Technology

[0002] After synthetic rubber undergoes processes such as extrusion dehydration, puffing and drying, supplemental drying, weighing and briquetting in the post-processing section, some rubber blocks with unacceptable moisture content will be produced (in actual production, especially during start-up and shutdown, an average of 5% of rubber blocks of each type have unacceptable moisture content). It would be a waste of resources to directly classify these blocks as defective simply because of their excessive moisture content. Crushing and reusing them as raw materials can effectively improve the yield of high-quality products.

[0003] When the crusher screw is working, it compresses the rubber block forward to the crusher template. The rubber passes through the template holes and becomes a cylindrical rubber strip, which is then cut into particles by the cutter located outside the template. The existing structure suffers from discontinuous material movement, significant leakage, and low efficiency due to the adjacent screw sleeves being distributed at 180° and the screw blades being straight plates with linear cutting edges. When working in conjunction with the fixed blades, under conditions of sufficient material, all the straight plates of the screw sleeves participate in shearing simultaneously, resulting in high power consumption, severe energy consumption, and significant noise pollution.

The arc-shaped head of the single-headed arc-shaped screw sleeve 122 pushes the material forward in a spiral. During the feeding process, the material comes into contact with the shearing groove to increase friction and prevent the material from being too sticky and sticking to the cylinder wall and the screw spindle 121. The material enters the pelletizing box 4. The pelletizing motor 10 drives the cutter shaft 31 to rotate through the belt. During the rotation, the cutter shaft 31 cuts the material into pellets through the cutter. The rubber material cut into pellets is discharged from the discharge port 9.

[0065] This utility model relates to a rubber crusher with a pusher screw, which reduces the torque during crushing and extrusion, improves crushing efficiency, ensures smooth and uniform discharge, produces uniform pellets, facilitates subsequent recycling, greatly increases the crusher's output, extends its service life, prevents material leakage, and reduces noise during operation.
