Description

Technical Field

[0001] The utility model relates to the technical field of cardboard punching, in particular to a positioning punching mechanism for processing packaging cardboard. Background Art

[0002] Packaging cardboard is a commonly used packaging material, usually made of paper or cardboard. It can be used to package various items, including food, cosmetics, toys, electrical appliances and other commodities. The main function of packaging cardboard is to protect the commodities from the influence of the external environment, keep the commodities neat and complete, and also help display and sell the commodities. When processing packaging cardboard, a punching machine is usually used to punch holes in it. Punching holes can increase the air permeability of the cardboard, help to discharge moisture and heat in the package, and thus maintain the quality of the commodities.

[0003] In the existing cardboard punching process, a punching machine is usually used to punch the cardboard. Since the operator needs to hold the cardboard with his hands to punch, it is easy to cause the position of the cardboard to shift, making it difficult to accurately locate the punching position, affecting the punching quality. After the punching is completed, waste chips often accumulate, which will affect the subsequent punching. The existing punching machine is unable to position the cardboard and clean up the inconvenient waste chips after positioning and punching.

[0004] In order to solve the above problems, the present application proposes a positioning and punching mechanism for processing packaging paperboard. Utility Model Content

The cardboard can be blown by the exhaust and blowing positioning member to cancel the suction force on the cardboard and take the cardboard out. In addition, the waste can be blown by the exhaust and blowing positioning member and the carrying exhaust and blowing member to prevent the cardboard from adhering to the carrying exhaust and blowing member. This structure can realize the positioning of the cardboard during the punching process to ensure the accuracy of the punching, and after the punching is completed, the waste generated by the punching can be cleaned up.
