[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-4 A cutting device for producing polyethylene sheets includes a support frame 1. Multiple auxiliary rollers 13 are rotatably mounted on the top front end of the support frame 1. The auxiliary rollers 13 are rotatably mounted inside the support frame 1, with only the topmost roller protruding and flush with the top of the support frame 1, to facilitate pushing the sheet material. Limiting side plates 12 are provided on both sides of the top front end of the support frame 1. A cutting frame structure 2 for cutting is provided in the middle of the support frame 1. A positioning limiting plate structure 16 is provided at the rear end of the support frame 1.

[0020] The cutting frame structure 2 is equipped with a first electric cylinder 3 at its top. The bottom telescopic power end of the first electric cylinder 3 extends into the cutting frame structure 2 and is equipped with a lifting guide rail 4. An adjusting screw 5 is rotatably mounted inside the lifting guide rail 4, and a slider 7 threadedly connected to the adjusting screw 5 is slidably mounted inside the lifting guide rail 4. A cutting structure 8 is mounted at the bottom of the slider 7. A motor 6 is mounted on one side of the lifting guide rail 4 to drive the adjusting screw 5 to rotate. That is, the first electric cylinder 3 can drive the lifting guide rail 4 and the bottom structure to perform lifting operations, and then the electrolysis 6 drives the adjusting screw 5 to rotate, thereby driving the cutting structure 8 to move laterally. The cutting structure 8 includes a supporting side plate frame 9, within which a cutting blade 10 is rotatably mounted. A drive motor 11 is located on one side of the supporting side plate frame 9 to drive the cutting blade 10 to rotate. The drive motor 11 drives the cutting blade 10 to rotate, cooperating with the aforementioned drive equipment to perform transverse cutting operations. A limiting sleeve 14 is located at the rear of the lifting guide rail 4, and a limiting block 15, penetrated by the limiting sleeve 14, is located at the rear of the supporting side plate frame 9. The limiting sleeve 14 and the limiting block 15 ensure stable transverse movement of the cutting structure 8.

[0021] The lifting guide rail 4 is provided with an elastic pressing structure 21 on its front side. The elastic pressing structure 21 includes a fixed plate 22 and an elastic plate 23 that is limited and sleeved in the fixed plate 22. The top of the elastic plate 23 extends into the fixed plate 22 and is provided with a limiting slide plate 24. The top of the limiting slide plate 24 is provided with multiple springs 25. The bottom of the elastic plate 23 is provided with a pressing plate 26. The elastic pressing structure 21 is provided on the front side of the lifting guide rail 4. At the same time, the height of the lowest end of the pressing plate 26 is lower than the height of the cutting blade 10. So when pressing down, the elastic plate 23 and the pressing plate 26 press the plate together, and then the cutting structure 8 performs the transverse cutting operation.

[0022] The limiting plate structure 16 has a second electric cylinder 17 at its rear end. The power end of the second electric cylinder 17 extends to one side of the cutting frame structure 2 and has a positioning moving plate 18. The second electric cylinder 17 can drive the positioning moving plate 18 to move, adjusting the distance between the front side of the positioning moving plate 18 and the cutting blade 10, thereby enabling rapid positioning of the sheet material. That is, the positioning moving plate 18 is first moved to a suitable position, and then the sheet material is directly pushed against the front side of the positioning moving plate 18 to complete the positioning, facilitating subsequent rapid cutting operations. The top of the rear end of the support frame 1 has multiple... The positioning moving plate 18 is equipped with a limiting slide groove 19. The bottom of the positioning moving plate 18 is provided with a limiting slider 20 extending into the limiting slide groove 19. A laser rangefinder 27 is provided on the front side of the limiting slider 20. The laser rangefinder 27 can be used to quickly observe specific values. In actual installation, precise debugging is required because the distance measured by the laser rangefinder 27 is the distance of the limiting slide groove 19, not the distance to the cutting blade 10. Therefore, during debugging, a small distance needs to be added in the programming process of the equipment controller, such as a microcontroller controller or a PLC controller.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
