Notching forming device for bag making machine

Abstract

The invention relates to the field of plastic bag preparation, in particular to a notching forming device for a bag making machine. The notching forming device comprises a machine body, a conveying belt arranged on the left side of the top of the machine body, a conveying groove formed in the right side of the top of the machine body, a grid plate arranged in the end of the conveying groove, a notching mechanism arranged above the top of the machine body and a material moving mechanism arranged above the top of the machine body; a rectangular notching frame is rotationally connected in the upper part of the machine body through a shaft rod; and a waste tank is obliquely and backwards erected in the lower part of the machine body. The rectangular notching frame is controlled to rotate by 90 degrees, so that waste falls into the waste tank under the gravity action of the waste and finally slides out of the machine body, the waste is automatically discharged, and notching forming of a next group of material bags is effectively prevented from being influenced; and a left folding plate and a right folding plate are controlled to be turned over and folded to reset in sequence, so that the material bags after notching forming are folded, each group of folded finished bags cannot be disordered, and the folded material bags can be conveniently arranged and encased.

Description

technical field [0001] The invention relates to the field of plastic bag preparation, in particular to a notch forming device for a bag making machine. Background technique [0002] Plastic bags have the characteristics of low price, one-time use, convenience and sanitation, 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 in large quantities and with high efficiency 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 gift bag forming system, including a bag making machine body, which includes a feeding device, a material cutting and forming device As well as the notch forming device, a material transfer device is arranged between the material cut...

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
