Rubber is a solid with high elasticity and toughness. Different processing scales, different processing conditions, and different varieties and properties of rubber.

By applying a pulling force to both sides of the cut of the rubber block during the cutting process of the rubber block, friction between the outer wall of the cutting knife and the rubber block is avoided, and the cut of the rubber block is prevented from being subjected to a high frictional force, thereby reducing the heat generated between the cutting knife and the rubber block.

[0004] During the use of the above patent, a pulling force is applied to both sides of the cut of the rubber block through a pressing block to avoid friction between the outer wall of the cutting knife and the rubber block.

[0082] The above embodiment discloses a high-efficiency rubber cutting machine. When in use, a rubber block is placed on the upper surface of a plurality of conveying rollers 202. At this time, the first motor 206 is started to drive the bidirectional lead screw 205 to rotate. At the same time, the two moving push seats 204 are driven by the threads on the outer wall of the bidirectional lead screw 205 and move along the inner wall of the guiding chute through the limiting sliders.

At the same time, the second bevel gear 2018 is driven to rotate by the connecting shaft under the meshing drive of the first bevel gear 2017. At this time, the clamping roller 201 rotates synchronously under the drive of the connecting rod 203. At the same time, through the rotation of the clamping roller 201 and the conveying roller 202, the rubber block can be centered and limited during the conveying process of the rubber block, so as to avoid situations such as deviation or inclination of the rubber block during cutting;

[0084] Meanwhile, the limit turntable 3010 rotates driven by a connecting shaft under the drive of a conveying roller 202. At this time, under the extrusion of the limit turntable 3010, the positioning plug 3011 pushes two limit slide rods 308 to slide along the inner wall of the fixed sleeve plate 3013 through the moving pressure plate 309. At the same time, the moving pressure plate 309 contracts through the moving compression spring 3012. At this time, the moving push plate 3014 is pushed by the two limit slide rods 308 to drive the ball 3015 to move and separate from the outer wall of the fixed sleeve plate 3013. When the limit turntable 3010 drives a positioning slot to move to the end of the positioning plug 3011, the spring 3012 rebounds to push the moving pressure plate 309 to insert the positioning plug 3011 into the inside of the limit turntable 3010, so as to limit the rotation of the limit turntable 3010;

[0085] When the rubber block moves to the specified position, stop the second motor 207 and start the electric push rod 6 to push the lifting seat 7 to descend. At the same time, the lifting clamping plate 306 vertically descends driven by the lifting seat 7 through the lifting slider 307 and contacts the outer walls of multiple balls 3015. At this time, the multiple balls 3015 rotate driven by the friction on the outer wall of the lifting clamping plate 306, effectively reducing the friction between the lifting clamping plate 306 and the moving push plate 3014. At the same time, through the contact between the lifting clamping plate 306 and the balls 3015, the moving push plate 3014 can be blocked, so as to avoid the situation of conveying the rubber block when the lifting seat 7 is not reset;

[0086] When the extrusion push plate 305 contacts the upper surface of the rubber block, the cutter 5 cuts the rubber block under the push of the electric push rod 6 through the lifting seat 7. During this process, the extrusion push plate 305 stops moving under the block of the rubber block. At the same time, the fixed guide plate 302 slides along the outer wall of the connecting push plate 301 driven by the lifting seat 7. At this time, the fixed guide plate 302 extrudes the outer wall of the moving slide rod 304 through the guiding inclined groove 303. At the same time, under the guiding of the inner wall of the guiding inclined groove 303, the moving slide rod 304 drives the extrusion push plate 305 to move horizontally through the connecting push plate 301. At this time, the cut part of the rubber block moves to both sides of the base 1 respectively under the push of the two extrusion push plates 305. The two extrusion push plates 305 can apply a pulling force to move the cut part of the rubber block to both sides, effectively preventing the rubber block from adhering to the outer wall of the cutter 5 during the process of the cutter 5 descending and cutting, thus preventing the rubber block from being drawn when being cut. Then start the electric push rod 6 to drive the cutter 5 to reset through the lifting seat 7, and then repeat the above operation, so as to achieve the purpose of efficiently cutting and conveying the rubber block.
