Punching mechanism of film bag making machine

Abstract

The invention relates to a punching mechanism of a film bag making machine. The punching mechanism comprises fixing frames, a punching plate, a puncher and a sliding frame, a tool bit receding hole is formed in the punching plate, the sliding frame and the punching plate are both arranged between the two fixing frames, the sliding frame is located above the punching plate, and a sliding locking device is arranged on the sliding frame; and the puncher is fixed to the sliding locking device and comprises a punching cutter set and a driver for driving the punching cutter set to move and shear, the driver is fixed to the sliding locking device, the punching cutter set faces the cutter bit receding hole, and a punching gap allowing a film to pass through is formed between the punching cutter set and the punching plate. The punching mechanism has the effect of improving accurate and smooth switching of the punching cutter set of the film bag making machine.

Description

technical field [0001] The invention relates to the technical field of film product manufacturing machinery, in particular to a punching mechanism of a film bag making machine. Background technique [0002] At present, in the packaging of electronic products, plastic film bags are the most commonly used. The existing plastic film bags mainly include a bag body with an opening. Electronic products play an effective role in protection. [0003] In the existing production process of plastic film bags, the most commonly used is the bag making machine. The bag making machine heat-seals and cuts the cylindrical plastic film raw materials to make plastic film bags of the required size, and in order to avoid The wrong use of plastic film bag causes the problem of suffocation, usually needs to carry out punching on plastic film bag, and the Chinese patent that authorized announcement number is CN209409467U discloses a kind of bag making machine punching device, and it passes through...

AI Technical Summary

Problems solved by technology

Although this punching method can perform the punching effect, it is easy to cause stretching deformation or tearing of the plastic film bag during the impact punching process, and its punching effect is poor, resulting in a low yield of the plastic film bag, and The punching device is inconvenient to move horizontally. The Chinese patent application publication number CN111086274A discloses a film bag making machine, which improves the stretching deformation and tearing of the film and improves a certain punching effect, but the punching component It is still inconvenient to move and switch, and the installation groove is long, and there is a slight skew along the length of the installation groove during the bolt fixing process, resulting in a decrease in the drilling effect
