Description

Technical Field

[0001] The utility model relates to the field of punching, and more specifically, to a cup cover punching device. Background Art

[0002] A plastic cup is a cup used to hold beverages or other liquids, and is mainly made of plastic material. During the production process of plastic cups, some cup lids need to be punched to facilitate users to drink the liquid or insert a straw, and a punching device is needed here.

[0003] Traditionally, punching is done manually, which is labor-intensive and has a low degree of automation, resulting in low working efficiency of the device. In order to solve the above problems, a Chinese patent with announcement number CN213859626U discloses a cup lid punching machine, which can realize automatic punching of the cup lid. However, the position of the punching mold in this scheme is fixed, and the spacing size of the pressure plates on both sides is also fixed. There is no structure that can adjust the punching position of the lid body. Only fixed positions of fixed-size cup lids can be punched, which cannot meet the changing market demand.

[0004] Based on the above, the purpose of the present invention is to provide a cup cover punching device to solve the above problems. Utility Model Content
