Under the action of the downward movement of the first belt roller 44, the first belt 45 is always kept in a tensioned state, which can increase the friction between the first belt roller 44 and the first belt 45, contributing to the stability of the slitting process;

[0032] As a further implementation of this solution, the number of the second belts 82 is two. The second belts 82 are fixedly connected to the left side and the right side of the second connecting column 83. The space between the second connecting columns 83 is the second cutting groove 84.

[0033] Workflow: When slitting the strip body 7, to prevent the end of the strip body 7 from skewing and ensure the slitting quality of the strip body 7, the strip body 7 is sleeved outside the winding roller 6, and one end of the strip body 7 is placed between the first connecting column 46 and the second connecting column 83 at the front end. The spring inside the spring telescopic rod 41 exerts a downward pulling force on the upper part of the spring telescopic rod 41. The spring telescopic rod 41 moves downward with respect to the concave plate 42, and the concave plate 42 drives the servo motor 43 and the first belt roller 44 to move downward. Under the action of the downward movement of the first belt roller 44, the first belt 45 is always kept in a tensioned state, which can ensure the stability of the rotation of the first belt 45 and at the same time increase the friction between the first belt roller 44 and the first belt 45. Start the servo motor 43, the servo motor 43 drives the first belt roller 44 to rotate, the first belt roller 44 drives the sleeved first belt 45 outside to rotate, the first belt 45 drives the first connecting column 46 to rotate. At this time, under the cooperation of the first connecting column 46 and the second connecting column 83, the strip bodies 7 are pulled, the strip bodies 7 drive the winding roller 6 to rotate, the winding roller 6 drives the built-in roller 5 to rotate, and the built-in roller 5 is rotatably connected to the inner side of the support frame 21, playing a role in limiting the built-in roller 5. The distance between the first cutting grooves 47 is the same as the distance between the second cutting grooves 84, and at the same time, the first cutting grooves 47 and the second cutting grooves 84 are in one-to-one correspondence and aligned. Under the action of the friction generated by the strip body 7 being in close contact with the second connecting column 83, the second connecting column 83 is driven to rotate, the second connecting column 83 drives the second belt 82 to rotate, and the second belt 82 drives the second belt roller 81 and the third belt roller 85 to rotate. The second belt roller 81 and the third belt roller 85 are rotatably connected to the inner side of the support frame 21, playing a role in limiting. When the strip body 7 rotates a certain distance, stop the servo motor 43, start the electric telescopic rod 23, the electric telescopic rod 23 pushes the cutter body 25 to move downward, the cutter body 25 cuts the strip body 7, and the cutter body 25 drives the limit roller 24 to move. The limit roller 24 is slidably connected to the inner side of the chassis shell 22, which can improve the stability of the lifting of the cutter body 25. The cutter body 25 passes through between the second cutting groove 84 and the first cutting groove 47. The second cutting groove 84 and the first cutting groove 47 facilitate the cutting operation of the cutter body 25 on the strip body 7. During cutting, through the extrusion cooperation of multiple second connecting columns 83 and the first connecting column 46, the function of fixing the strip body 7 is realized, the stability of cutting is improved, and at the same time, through the cooperation between multiple second connecting columns 83 and the first connecting column 46, the end of the strip body 7 can be prevented from shifting, the cut end will not move, ensuring the cutting quality of the strip body 7 again. The cut strip body 7 is transported above the collection box 1 through the second connecting column 83 and the first connecting column 46 and collected by the collection box 1.
