A punching and forming device for a bag making machine

Abstract

The invention relates to the field of plastic bag preparation, in particular to a punching and forming device for a bag making machine, comprising a body, a conveying belt arranged on the left side of the top of the body, a conveying trough arranged on the right side of the top of the body, and a conveying trough There is a grid plate in the end, a punching mechanism arranged above the top of the body, and a material moving mechanism arranged above the top of the body. The upper part of the body is connected with a rectangular punching frame through the rotation of the shaft, and the lower part of the body is inclined backward. Waste chute; the present invention controls the rectangular punching frame to rotate 90°, so that the waste material falls into the waste material chute under the action of gravity, and finally slides out of the body to realize automatic waste removal and effectively avoid punching the next set of material bags. Forming will have an impact; by controlling the left folding plate and the right folding plate to turn over and fold back to their original position successively, the bag after the punch opening is folded, so that each group of folded bags will not be confused with each other, and it is convenient to fold the folded bag. Packing and packing bags.

Description

technical field [0001] The invention relates to the field of plastic bag preparation, in particular to a punching and forming device for a bag making machine. Background technique [0002] Plastic bags have the characteristics of low price, one-time use, convenience and hygiene, etc. In daily life, the application of plastic bags is very common; due to the large amount of plastic bags, the production of plastic bags is increasingly automated, in order to be able to produce large quantities and efficiently. Plastic bags, therefore, high-speed automatic bag making machine came into being. [0003] A bag making machine is a machine for making various plastic packaging bags. For example, the Chinese patent number "202020112986.2" discloses a molding system for gift bags, including a bag making machine body, which includes a feeding device and a cutting and forming device. and a punching forming device, a material moving device is arranged between the cutting forming device and ...

AI Technical Summary

Problems solved by technology

[0007] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides a notch forming device for a bag making machine, which can effectively solve the problem that the prior art does not completely push out the waste, which affects the notch forming of the next group of bags. The bag after punching is not sorted and folded, which affects the forming and packing of the bag after punching
