Upper edge processing equipment of paper bag

Abstract

The invention discloses upper edge processing equipment of a paper bag. The upper edge processing equipment comprises a handle forming mechanism for generating a strip-shaped handle, a handle feedingmechanism for conveying the strip-shaped handle, a handle cutting mechanism for cutting the strip-shaped handle, a single-handle transferring mechanism for conveying a single handle, a paper bag upperedge cutting mechanism for cutting the paper bag upper edge, a handle bonding mechanism for adhering the single handle to the paper bag upper edge, a paper bag body cutting mechanism for cutting a paper bag body and a paper bag upper edge folding and gluing mechanism for folding and gluing the paper bag upper edge, wherein a handle feeding assembly comprises a positioning roller unit, a first rotating roller unit, a second rotating roller unit and a pressing roller unit, and the positioning roller unit comprises a positioning pin assembly. The positioning pin assembly can be inserted into positioning holes of the handle paper bag in the conveying process of the handle paper bag, so that the conveying speed of the paper bag is ensured to be stable, the consistency of the cutting length ofthe handle is ensured, and the quality of the paper bag is improved.

Description

technical field [0001] The invention relates to the technical field of paper bag processing equipment, in particular to an upper edge processing equipment of a paper bag. Background technique [0002] Paper tote bags are widely used in various fields because of their recyclability and low cost. Usually, the handbag includes a bag body for holding articles and a handle bonded on the top of the bag body. In the paper bag production process, the processing of the upper edge of the paper bag includes the processing of the paper tape handle and the bonding of the paper bag handle to the upper edge of the paper bag. [0003] The handle is generally a strip handle formed by a handle forming machine, and then cut to form a single handle. There are two ways for the existing handle to be bonded to the paper bag body: 1. The strip handle is directly cut on the handle forming machine to form a single handle, which is then bonded manually; 2. The strip handle is made of The paper tape...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a paper bag upper edge processing equipment, which solves the problem that the existing paper bag upper edge processing equipment easily causes the paper bag handle to be unsteady in transmission, easily causes the handle to be cut in inconsistent lengths, and affects the quality of the paper bag.
