Description

Technical Field

[0001] The utility model relates to the technical field of bicycle processing equipment, in particular to a cutting device. Background Art

[0002] Anti-counterfeiting labels (also called anti-counterfeiting labels or anti-counterfeiting stickers) are a type of self-adhesive product that can be pasted, printed, or transferred on the surface of the target object, or on the packaging of the target object, or on the accessories of the target object. It has an anti-counterfeiting function. The anti-counterfeiting characteristics of the anti-counterfeiting label and the identification method are the soul of the anti-counterfeiting label. With the vigorous promotion of the concept of green environmental protection, bicycles have become the only choice for people's transportation in life. During the production process of existing bicycles, anti-counterfeiting labels are usually affixed to the five-way position of the bicycle frame.

The utility model sets a second slider, a cutting knife and a pressing plate. Under the elastic action of the pressing spring, the two pressing plates press and fix the anti-counterfeit labels on the conveyor belt, and multiple groups of cutting knives cut the anti-counterfeit labels at the same time, cutting them into multiple units of anti-counterfeit labels, greatly improving the efficiency and accuracy of cutting and reducing production costs.

[0004] However, the above scheme still has the following problems: the overall equipment is not effectively positioned during cutting, which causes the overall equipment to shake to varying degrees, affecting the normal cutting stability. At the same time, the debris is not recovered during cutting, which easily causes varying degrees of blockage in the equipment and increases the labor intensity of manual cleaning. Therefore, it is necessary to design a cutting device to solve the above problems. Utility Model Content
