[0071] The above embodiment discloses a high-efficiency rubber cutting machine, wherein, when in use, the rubber block is placed on the upper surface of a plurality of conveying rollers 202, and the first motor 206 is started to drive the bidirectional screw rod 205 to rotate, and at the same time, the two movable push seats 204 are driven by the outer wall threads of the bidirectional screw rod 205 to move along the inner wall of the guide slide groove through the limit slider, and in this process, the first bevel gear 2017 slides along the outer wall of the transmission rotating rod 2016 through the limit rotating ring 2015 driven by the movable push seat 204, and at the same time, the connecting rotating rod 203 drives the clamping roller 201 and the second bevel gear 2018 to move synchronously through the connecting shaft driven by the movable push seat 204, and when the two groups of clamping rollers 201 are respectively in contact with the outer walls of the two ends of the rubber block, the first motor 206 is stopped, thereby realizing the automatic centering operation of the rubber block;
[0072] Then, the second motor 207 is started to drive a synchronous roller 209 to rotate. At this time, the conveyor belt 208 is driven by one synchronous roller 209 to drive another synchronous roller 209 to rotate synchronously. At the same time, the first transmission disk 2010 is driven by a synchronous roller 209 through the connecting shaft, and the transmission plate 2011 is driven to move through the rotating shaft. At this time, the transmission frame 2014 is driven by the transmission plate 2011 to rotate through the rotating shaft respectively. In this process, the conveying roller 202 is driven by the third transmission disk 2013 to rotate through the connecting shaft. At the same time, the transmission rod 2016 is driven by the connecting shaft. The second transmission disk 2012 is driven to rotate. At this time, the first bevel gear 2017 drives the limiting swivel 2015 to rotate along the inner wall of the moving push seat 204 through the moving slider and the linear slide groove of the transmission rotating rod 2016. At the same time, the second bevel gear 2018 drives the connecting rotating rod 203 to rotate through the connecting shaft under the meshing drive of the first bevel gear 2017.

At the same time, through the rotation of the clamping roller 201 and the conveying roller 202, the rubber block can be centered during the conveying process of the rubber block, so as to avoid the rubber block from being offset or tilted when being cut;
[0073] At the same time, the limit turntable 3010 is driven by a conveying roller 202 to rotate through the connecting shaft. At this time, the positioning plug block 3011 is squeezed by the limit turntable 3010 and pushes the two limit slide bars 308 to slide along the inner wall of the fixed sleeve 3013 through the moving pressure plate 309. At the same time, the moving pressure plate 309 is contracted by the moving extrusion spring 3012.

When the limit turntable 3010 drives a positioning slot to move to the end of the positioning plug block 3011, the spring 3012 pushes the moving pressure plate 309 through rebound to make the positioning plug block 3011 inserted into the interior of the limit turntable 3010, so that the limit turntable 3010 can be limited in rotation.
[0074] When the rubber block moves to the specified position, the second motor 207 is stopped and the electric push rod 6 is started to push the lifting seat 7 down. At the same time, the lifting card plate 306 is driven by the lifting seat 7 to vertically drop through the lifting slider 307 and contact the outer wall of the plurality of balls 3015. At this time, the plurality of balls 3015 rotate under the friction of the outer wall of the lifting card plate 306, thereby effectively reducing the friction between the lifting card plate 306 and the moving push plate 3014. At the same time, the contact between the lifting card plate 306 and the balls 3015 can block the moving push plate 3014, thereby preventing the lifting seat 7 from conveying the rubber block when it is not reset.
[0075] When the extrusion push plate 305 contacts the upper surface of the rubber block, the cutter 5 cuts the rubber block through the lifting seat 7 under the push of the electric push rod 6. In this process, the extrusion push plate 305 stops moving under the obstruction of the rubber block, and 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 squeezes the outer wall of the moving slide bar 304 through the guide inclined groove 303. At the same time, the moving slide bar 304 drives the extrusion push plate 305 to move horizontally through the connecting push plate 301 under the guidance of the inner wall of the guide inclined groove 303. The cut part of the rubber block moves to both sides of the base 1 under the push of the two extrusion push plates 305. The two extrusion push plates 305 can apply a pulling force to the cut part of the rubber block to move it to both sides, thereby effectively preventing the rubber block from sticking to the outer wall of the cutter 5 during the process of the cutter 5 descending and cutting, thereby preventing the rubber block from being drawn when being cut. Then, the electric push rod 6 is started to drive the cutter 5 to reset through the lifting seat 7, and then the above operation is repeated, so as to achieve the purpose of efficiently cutting and conveying the rubber block.
