Automatic bundling device of plastic bag making machine

Abstract

The invention provides an automatic bundling device of a plastic bag making machine. The automatic bundling device comprises a plastic bag feeding mechanism, a rubber band arranging and output mechanism and a bundling mechanism. The bundling mechanism comprises an opening device and a rubber band transfer mechanism. The rubber band transfer mechanism is used for transferring rubber bands output bythe rubber band arranging and output mechanism to the opening device. The opening device is used for opening each rubber band and sleeving the rubber band onto a stack of plastic bags. The automaticbundling device has the advantages that the automatic bundling device can implement automatic bundling of soft thin film products and improves the working efficiency; through arranging of a lower rubber band output channel of the rubber band arranging and output mechanism, the rubber bands can be prevented from getting accumulated and blocked and can be conveyed smoothly; through the combination effect of band release convex heads of band release plates arranged on the outer side of a band release plate of the opening device and brace rod grooves formed in the circumferential surfaces of rubber band brace rods, the situation that rubber bands cannot be kept away from the rubber band brace rods can be effectively prevented, and the working reliability of band release is improved.

Description

technical field [0001] The invention relates to an automatic binding device of a plastic bag making machine, which is mainly used for automatically binding the folded plastic bags made by the plastic bag making machine with rubber bands. It can also be used for automatic bundling of other stacks or rolls of soft film products. Background technique [0002] At present, there is a lack of rubber bands on the market for bundling some film materials folded into strips. Traditional bundling is done manually, which is time-consuming and labor-intensive, and a single action for a long time is likely to cause fatigue of workers, reduce work efficiency, and easily Cause occupational diseases, indirectly increase production costs and reduce production efficiency. Later someone invented an automatic strapping device, which mainly includes a rubber band sorting output mechanism and a strapping mechanism, which lacks a feeding mechanism for conveying products; The rubber band is often ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic strapping device for a plastic bag making machine to solve the lack of a feeding mechanism for conveying products in the prior art; The rubber band on the device is often stuck on the spreader rod when it is pulled out with the stripping board
