The primary adjustment mechanism includes two moving plates 13, which are symmetrically arranged front and back. A secondary adjustment mechanism is set at the bottom of each of the two moving plates 13. A fixed cutter 18 and a movable cutter 21 are fixedly connected at the bottom of the secondary adjustment mechanism. Guide rails 3 26 are fixedly connected to the opposite side walls of the left and right vertical plates 7. The guide rails 3 26 extend vertically. Sliding sliders 3 27 are slidably engaged on the guide rails 3 26. The sliding sliders 3 27 are fixedly connected to the outer walls of both sides of the lifting plate 10.

[0019] The primary adjustment mechanism includes two guide rails 11, which are distributed on the left and right sides. The guide rails 11 are fixedly connected to the bottom of the lifting plate 10. The front and rear ends of the lifting plate 10 extend downwards. A bidirectional lead screw 12 is located between the two guide rails 11. The front and rear ends of the bidirectional lead screw 12 are rotatably connected to the middle of the front and rear ends of the lifting plate 10, respectively. Two moving plates 13 are located on the front and rear sides of the bottom of the bidirectional lead screw 12, respectively. A connecting block 14 is fixedly connected to the top of the moving plate 13. The connecting block 14 is threaded onto the bidirectional lead screw 12. The bidirectional lead screw 12 passes through the connecting block 14. Slider 15 is fixedly connected to the four corners of the top of the moving plate 13. The slider 15 is slidably engaged with the bottom of the guide rail 11. A motor 16 is fixedly installed at the rear end of the lifting plate 10. The rear end of the bidirectional lead screw 12 passes through the outer wall of the lifting plate 10. The output shaft of the motor 16 is fixedly connected to the rear end of the bidirectional lead screw 12.

[0020] The secondary adjustment mechanism is fixed to the bottom of the movable plate 13. The secondary adjustment mechanism includes a fixed block 17. Two fixed blocks 17 are fixedly connected to the bottom sides of the opposite ends of the two movable plates 13 respectively. A fixed cutter 18 is fixedly connected to the bottom of the fixed block 17. Guide rails 19 are fixedly connected to the left and right sides of the bottom of the movable plate 13. Sliding blocks 20 are slidably sleeved on the outer wall of the guide rails 19. A movable cutter 21 is fixedly connected between the bottoms of the two sliding blocks 20. A connecting block 22 is fixedly connected to the top center of the movable cutter 21. A connecting frame 23 is fixedly connected to the bottom of the opposite ends of the two movable plates 13. A motor 24 is fixedly installed in the middle of the connecting frame 23. The end of the linear screw 25 passes through the middle of the connecting frame 23.

The linear screw 25 passes through the connecting block 22. The connecting block 22 is threadedly connected to the linear screw 25.

[0021] A corrugated pipe is fitted onto the outer wall of the bidirectional lead screw 12 and the linear lead screw 25. The corrugated pipe serves as a dustproof device.

[0022] The moving plate 13 is driven to move back and forth by the bidirectional lead screw 12 of the primary adjustment mechanism to set the group spacing between the fixed cutter 18 and the movable cutter 21; the movable cutter 21 is driven to move left and right by the linear lead screw 25 of the secondary adjustment mechanism to set the distance between a single group of cutters, thereby achieving the pre-adjustment of the adhesive strip width.

[0023] Rubber block 28 is placed on straight roller 4. The front and rear positions of support rod 5 can be adjusted through sliding hole 3. After loosening lock nut 6, slide support rod 5 between movable cutter 21 and fixed cutter 18 to avoid straight roller 4 being directly below movable cutter 21 and fixed cutter 18. Movable cutter 21 and fixed cutter 18 need to pass through the gap between two adjacent straight rollers 4 vertically to prevent movable cutter 21 and fixed cutter 18 from colliding with straight roller 4. Then tighten lock nut 6 to fix it and ensure that rubber block 28 is stably supported.

[0024] When the electric cylinder 9 is activated, the piston rod pushes the lifting plate 10 to move vertically downward along the guide rail 26, causing all the movable cutters 21 and the fixed cutter 18 to press down synchronously; the rubber material is cut under the synergistic action of the fixed cutter 18 and the movable cutter 21, and the electric cylinder 9 provides stable high pressure to ensure that the highly elastic rubber is cut in one go.

[0025] Motor 16 drives the bidirectional lead screw 12 to rotate, causing the front and rear moving plates 13 to move synchronously towards or away from each other, thereby adjusting the overall distribution of the fixed cutter 18 and the movable cutter 21 to adapt to different cutter arrangement requirements.

[0026] Motor 24 drives linear screw 25 to rotate, which in turn drives connecting block 22 and movable cutter 21 to slide laterally along guide rail 29, thereby enabling fine adjustment of the blade distance between fixed cutter 18 and movable cutter 21 to meet the customized requirements of adhesive strip width.

[0027] After cutting is completed, the electric cylinder 9 raises the lifting plate 10, and the fixed cutter 18 and the movable cutter 21 return to the high position. The operator takes out the cut rubber block from the straight roller 4, completing a single operation cycle.
