Abstract

This utility model discloses a rubber cutting device for a rubber mixing mill, including a base with multiple sets of first rollers rotatably connected to it. Grooves are provided at one and the other ends of the base, and multiple sets of push rods are mounted on the base. When the reciprocating screw is driven by a motor, it drives the screw sleeve to move the frame and the blade body laterally back and forth. This allows different parts of the blade to participate in cutting the rubber conveyed between the first and second rollers, removing burrs and other impurities. This results in a wider distribution of wear on the blade. Simultaneously, the lateral reciprocating movement disperses heat across different parts of the blade, reducing the possibility of localized overheating. This helps maintain the performance of the blade body, slows down wear caused by softening and deformation of the blade material due to high temperatures, extends the service life of the blade body, reduces the frequency of blade replacement, and avoids unnecessary waste.
