[0034] Reference Figure 1 , Figure 5 and Figure 6 The disassembly assembly includes a fixed block 18, which is used to provide structural support for disassembly. The fixed block 18 is fixedly connected to the inside of the housing 1. A push column 19 is slidably connected inside the fixed block 18. The push column 19 is used to control the movement of the internal structure to facilitate the removal of the processed material 17. A spring 3 20 is sleeved on the outer periphery of the front end of the push column 19. The spring 3 20 is used to push the push column 19 to reset it. The rear end of the spring 3 20 is fixedly connected to the middle of the push column 19, and the front end of the spring 3 20 is fixedly connected to the fixed block 18. Inside, the push column 19 is slidably connected with a latch 22, and the push column 19 is slidably connected with a limit plate 21. The limit plate 21 is used to prevent the latch 22 from falling off when it moves.

[0035] Working principle: When using the equipment, you first need to install the processing material 17, push the push column 19, the push column 19 will slide forward in the fixed block 18, because the latch 22 loses the extrusion of the inner wall of the fixed block 18, the latch 22 will pop out to open the installation position, align the processing material 17 slot with the inside of the latch 22 and push it in, then release the push column 19, under the pulling force of the spring three 20, the latch 22 will be squeezed into the slot, thereby completing the installation of the processing material 17, refer to the installation steps to complete the disassembly, and then complete the material arrangement, start the motor two 7, the motor two 7 will drive the threaded rod 6 to drive the lifting frame 4 to descend, when the two rollers one 2 and the two rollers two 12 clamp the material, it can also continue to go down The clamping pressure is increased. Since there are multiple springs 10 in the lifting frame 4, they can play a buffering role. Then the motor 3 is started, and the motor 3 will pull the material backward. Since the roller on the right is connected to the ratchet 13, a slider 15 is arranged on the outside of the ratchet 13. When the material is not tight enough, the friction force exerted on the roller 2 12 will not be enough for the ratchet 13 to push the multiple sliders 15. At this time, the roller 2 12 on the right will not rotate until the roller 1 2 and roller 2 12 on the left tighten the material. When the material is over-tightened, the roller 2 12 on the right will be subjected to sufficient friction. At this time, the ratchet 13 can break through the resistance brought by the multiple sliders 15 and force the roller 2 12 on the right to rotate, thereby alleviating the excessive tension of the material.
