The two connecting blocks 232 are respectively slidably connected to the inside of the two U-shaped blocks 231. The two threaded holes 233 are respectively opened on the front of the two connecting blocks 232 and pass through the back thereof. The two threaded rods 234 are respectively arranged on the right side of the two U-shaped blocks 231 and extend to the inside of the two threaded holes 233 respectively. The two threaded rods 234 are respectively threadedly connected to the two threaded holes 233, and the two knobs 235 are respectively arranged on the right side of the two threaded rods 234.

[0035] When the threaded rod 234 is threadedly connected to the threaded hole 233, the connecting block 232 can be fixed to the inside of the U-shaped block 231, thereby fixing the guide roller 22. By replacing the guide roller 22, rubbers of different specifications can be transported through the limiting grooves 24 of different specifications, ensuring that the rubbers of different specifications can be limited by the limiting grooves 24 when transporting rubbers of different specifications, thereby ensuring the stability of the rubber during transportation.

[0039] It should be noted that when the rubber is being transported, the rubber on the left side will fall to the top of the support plate 51, and then the cylinder 53 will be started. The piston rod of the cylinder 53 will drive the lifting plate 54 to move downward, and the lifting plate 54 will drive the cutting knife 56 to move downward. The rubber can be cut by the cutting knife 56, and the top of the support plate 51 is provided with a cutting groove to ensure that the cutting knife 56 can completely cut the rubber, and the lifting plate 54 can be guided by two guide rods 55 to ensure the stability of the movement of the lifting plate 54, and further ensure the stability of the cutting knife 56 during movement.

The drive motor 41 and the cylinder 53 can be controlled by the controller, and when the drive motor 41 and the cylinder 53 are controlled by the controller, the drive motor 41 and the cylinder 53 are started alternately. When the drive motor 41 is started, the rubber can be stably transmitted. After being transmitted to a certain length, the drive motor 41 stops, and then the cylinder 53 is started.
