Paper packaging bag forming mechanism

Abstract

The invention discloses a paper packaging bag forming mechanism. The paper packaging bag forming mechanism comprises a rack, edge folding guide plates, a former and a shaping roller. The rack is sequentially provided with a bracket plate, a carrier roller, the former, an extrusion roller and the shaping roller in the conveying direction. The bracket plate is fixedly arranged on the rack. The two sides of the bracket plate are provided with material guide edges which are tilted inwards in the conveying direction. The bracket plate is provided with a rotating groove. The carrier roller with the two ends arranged on the rack in a rotating mode is arranged in the rotating groove. The front end of the bracket plate is connected with the former. The two sides of the former are both provided with the edge folding guide plates. The edge folding guide plates comprise upper guide plate bodies and lower guide plate bodies. The inlet ends of the upper guide plate bodies are provided with arc bent plates which are in arc transition connection with the lower guide plate bodies. The paper packaging bag forming mechanism is compact in structural design, good guide tracks are obtained, paper bag conveying deviation is avoided, the forming effect of paper bags is good, working efficiency is improved, and meanwhile product quality of the paper bags is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging molding, in particular to a paper packaging bag molding mechanism. Background technique [0002] Paper bags have many advantages such as light weight, low price, wide range of sizes and recyclability, and are widely used in various industries. The traditional production of food paper bags generally involves a series of operations such as edge folding, forming, bag cutting, gluing, bottom folding, bottom paste, and finished bag output. However, the folding and forming process of paper bags requires manual labor, which not only requires a large amount of labor, but also has low processing efficiency and unstable product quality; although there are some paper bag forming equipment disclosed on the market, these equipment structures are relatively complicated. The forming effect is poor, which greatly reduces the product quality of the paper bag. Contents of the invention [0003] The object of ...
