Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag processing, and particularly relates to a plastic bag punching device. Background Technique

[0002] As is well known, plastic bags are bags made of plastic as raw materials and are used for various articles in production and life. They are widely used in daily life and industrial production. However, this temporary convenience brings long-term harm. Commonly used plastic bags are mostly made of polyethylene film, which is non-toxic and can be used to contain food. There is also a kind of film made of polyvinyl chloride. Polyvinyl chloride itself is also non-toxic, but the additives added according to the use of the film are often harmful substances to the human body and have certain toxicity. Therefore, such films and plastic bags made of such films are not suitable for containing food. When plastic bags are produced and processed, they need to be punched, so a punching device is required.

[0003] The patent with the application number CN202320857742.0 discloses a plastic bag punching device, including a base. A punching table is arranged at the top end of the base. Through holes are arranged on the top surface of the punching table. One side of the base is fixedly connected with a support plate. An installation block is fixedly connected to the top end of the support plate. A hydraulic cylinder is fixedly connected to the bottom end of the installation block. A punching punch is arranged at the bottom end of the hydraulic cylinder. A cavity is arranged inside the punching punch. An air pump is arranged inside the installation block. The air pump is communicated with the cavity inside the punching punch through an air pipe.

[0004] Although this device improves the punching effect to a certain extent, when staff use this device to punch plastic bags, they need to manually adjust the punching position of the plastic bag. For plastic bags of different models, the punching positions are different. And it is very difficult for staff to accurately control the punching position manually. For some new employees, the accuracy of controlling the punching position of plastic bags will be worse. Therefore, there will be some unqualified products among the punched plastic bags, so the practicability is not very good and there is still room for improvement. Content of the Utility Model
