Description

Technical Field

[0001] The utility model relates to the technical field of punching bags, in particular to a punching device for special-shaped plastic bags. Background Technique

[0002] During the processing of food packaging bags, they are generally formed by a heat-sealing bag-making machine. In the prior art, the heat-sealing bag-making machine mainly includes a feeding roller, a flattening device, a bonding device, a hot cutting and sealing device, an ironing device, and a discharging device connected in sequence. The whole roll of plastic film is placed on the feeding roller, then flattened by the flattening device, bonded by the bonding device, cut and sealed by the hot cutting and sealing device, ironed by the ironing device, and finally discharged to form a plastic bag. The packaging bag formed by the above structure has a bag opening. Users put the goods into the packaging bag from the bag opening, seal it and then sell it. During this process, gas is likely to enter the plastic bag, causing the plastic bag to expand, which brings inconvenience to the transportation of goods. Therefore, a punching device is needed to punch holes in the plastic bag.

[0003] In the process of realizing the present utility model, the inventor found that the following problems in the prior art have not been solved: Although the existing punching device for special-shaped plastic bags has a good punching effect, when the punching cylinder moves up and down reciprocally driven by the push rod motor for punching operations, it is necessary to manually and frequently control the motor artificially, which causes unnecessary burden and affects the punching efficiency to a certain extent.
