Description

Technical Field

[0001] The invention relates to the technical field of plastic product cutting, in particular to a cutting device for producing plastic products. Background Art

[0002] The cutting equipment for plastic product production is an efficient cutting tool. The cutting equipment mainly relies on pressure to cut plastic products through special blades. The blade is quickly pressed down under pressure to cut the plastic products. After the cutting is completed, the blade automatically resets and waits for the next cutting, so that the pressure cutting equipment can achieve efficient and continuous cutting operations. The cutting equipment is widely used in the primary and deep processing of plastic products, such as cutting plastic sheets, films, pipes, etc. In the production of packaging materials, the cutting equipment can be used in the manufacture of electronic products. The cutting equipment can be used to cut the raw materials of plastic shells, plastic panels and other components with different spacings, providing accurate and efficient cutting of scrap materials for the manufacture of electronic products.

[0003] During the cutting process of existing plastic product production cutting equipment, when replacing plastic product thin plates of different sizes, it is necessary to readjust the plastic product thin plate limiting device, and manually adjust the spacing between several cutting knives, and adjust the cutting knife spacing according to the cutting size required for the plastic product thin plates of different sizes. Each time the thin plate size is changed, it takes time to adjust the limiting device and the cutting knife spacing, which directly increases the production preparation time and reduces the overall production efficiency. Manual adjustment requires precise operating skills and experience. Improper adjustment leads to cutting errors, which in turn affects product quality. When manually adjusting the cutting knife spacing, inaccurate operation leads to cutting size deviations, affecting the dimensional accuracy and appearance quality of the product. During the manual adjustment process, the operator faces the risk of being scratched by the cutting knife. Summary of the invention
