[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a drive motor to drive a sliding lead screw, with a sliding block sliding along the lead screw, thereby causing the lifting rod and cutting blade to move horizontally. This design allows the cutting blade to be flexibly adjusted in the horizontal direction to adapt to the cutting needs of plastic films of different widths without replacing the entire cutting device, thus improving the equipment's versatility and flexibility. The connecting components adopt a modular design, including a lower connecting seat, a connecting groove, a connecting block, an upper connecting seat, and a connecting bolt. The cutting blade is detachably mounted on the lower connecting seat via the connecting bolt, facilitating quick replacement of cutting blades of different specifications to adapt to different cutting needs. At the same time, this design also simplifies the daily maintenance process of the equipment and reduces maintenance costs.

[0014] This invention uses a lifting motor to drive a lifting screw, which causes the lifting block to move the cutting blade vertically up and down. Combined with a limiting plate, it ensures stability and precision during the cutting process. This vertical adjustment mechanism effectively reduces tearing and burrs during cutting, ensuring the flatness of the cut surface and the overall quality of the product. Attached Figure Description
