A third magnet block 22 is slidably fitted in the cooling water pipe 20, and a second spring 23 is fixedly connected between the third magnet block 22 and the inner wall of the annular water pipe 21. The surface of the first strip-shaped plate 16 facing the annular water pipe 21 is fixedly provided with a mounting seat 24 corresponding to the position of the third magnet block 22, and the mounting seat 24 is fixedly provided with a fourth magnet block 25. When the circular end plate 5 drives the cooling water pipe 20, the annular water pipe 21 and the third magnet block 22 to rotate, when the third magnet block 22 reaches a position corresponding to the fourth magnet block 25, mutual repulsion force is generated between the two, the third magnet block 22 is pushed to slide in the cooling water pipe 20 under the action of the mutual repulsion force, the second spring 23 is stretched, meanwhile, the cooling water in the cooling water pipe 20 is pushed into the cooling water tank 19 by the third magnet block 22, and the cooling water in the annular water pipe 21 enters the cooling water pipe 20. When the third magnet block 22 leaves the position corresponding to the fourth magnet block 25, the mutual repulsion force between the third magnet block and the fourth magnet block disappears, the third magnet block 22 is reset under the action of the resilience force of the second spring 23, the cooling water in the cooling water pipe 20 enters the annular water pipe 21, and the cooling water in the cooling water tank 19 enters the cooling water pipe 20; thereby the mobility of the cooling water in the cooling water tank 19, the cooling water pipe 20 and the annular water pipe 21 is improved, the cooling effect of the cooling water in the cooling water tank 19 is further ensured, and the rubber strip can be rapidly cooled.
The guide mechanism 7 includes a mounting plate 71 fixedly mounted on the upper surface of the base plate 1, and a support bracket 72 corresponding to the position of the disk 6 is horizontally and fixedly mounted on the mounting plate 71 facing the surface of the disk 6. The bottom surface of the support bracket 72 is tangent to the highest point of the circumferential surface of the disc 6. The mounting plate 71 is provided with a through-groove 73 corresponding to the position of the support bracket 72. The rubber strip is placed on the support bracket 72 after passing through the through slot 73, and the end of the rubber strip extends out of the support bracket 72 and is attached to the highest point on the outer circumferential surface of the disc 6. Two side walls of the mounting plate 71 are horizontally and slidably matched with the triangular brackets 2127474, and the two Contraband-shaped brackets 74 are symmetrical to each other. The end of the Contraband-shaped frame 74 extends into the through slot 73 and is rotatably mounted with a vertical pressure roller 75. An adjusting screw 76 which penetrates through the vertical section of the Contraband-shaped frame 74 is horizontally and rotatably arranged on the side wall of the mounting plate 71. The Contraband-shaped frame 74 and the compression roller 75 are driven to horizontally move by rotating the adjusting screw 76 until the compression roller 75 is attached to the rubber strip, and the rubber strip is compressed by the two compression rollers 75 to play a tensioning role, so that the rubber strip is prevented from loosening, the rubber strip is ensured to be tightly attached to the circumferential surface of the disc 6 under the action of the clamping mechanism 18 before cutting, and the cutting length is further ensured to be uniform.
The clamping mechanism 18 comprises a clamping rod 181 which penetrates through the round end plate 5 in an axial sliding manner along the round end plate 5, and a clamping block 182 is fixedly installed at the end part, facing the disc 6, of the clamping rod 181. The end part of the clamping rod 181 far away from the disc 6 is fixedly provided with a fifth magnet block 183, and a third spring 184 sleeved on the clamping rod 181 is fixedly connected between the fifth magnet block 183 and the circular end plate 5.

The circular end plate 5 is provided with an accommodating groove 185 arranged along the axial direction, and the clamping rod 181 is fixedly provided with a sliding block 186 which is in sliding fit with the accommodating groove 185. The slider 186 is fixedly provided with a mushroom button 187, and the accommodating groove 185 is provided with a clamping groove 188 matched with the mushroom button 187. When the round end plate 5 and the round disc 6 rotate, the clamping mechanism 18 is driven to rotate synchronously, and when the fifth magnet block 183 rotates to a position corresponding to the second magnet block 17, mutual repulsion force is generated between the fifth magnet block 183 and the second magnet block, the clamping rod 181 and the clamping block 182 are pushed to move by the action of the mutual repulsion force, and the third spring 184 is compressed. The clamping rod 181 drives the sliding block 186 and the mushroom button 187 to slide in the accommodating groove 185 until the mushroom button 187 is clamped into the clamping groove 188, and at the moment, the clamping blocks 182 are attached to the rubber strip, so that the rubber strip is clamped through the two clamping blocks 182. As the end plate 5 and the disc 6 continue to rotate, the rubber strip is stretched by the two clamping blocks 182 and is applied to the circumferential surface of the disc 6 until the rubber strip is cut by the cutting blade 10. The cut rubber strip continues to follow the rotation of the circular end plate 5 and the circular disc 60 under the action of the two clamping blocks 182. When the fifth magnet block 183 reaches a position corresponding to the sixth magnet block 27, an attractive force is generated between the fifth magnet block 183 and the sixth magnet block 27, the mushroom clip 187 is disengaged from the engaging groove 188 by the attractive force and the resilient force of the third spring 184, the fifth magnet block 183, the clamping rod 181, and the clamping block 182 are reset, the clamping block 182 releases the clamping action on the rubber strip, and the rubber strip freely falls down to the upper surface of the base plate 1.
