Processing device for preventing inner plastic bag electrostatic adsorption

Abstract

The invention discloses a processing device for preventing inner plastic bag electrostatic adsorption. The device comprises a combination superposition work station, a combination superposition roll, a forming mechanism, a guide roll, a cylinder, an air gun, a traction roll, and a cutter. The combination superposition roll is mounted on the combination superposition work station, the forming mechanism is mounted behind the combination superposition work station, the guide roll is mounted at the front lower part of the forming mechanism, the cylinder is mounted at the lower part of the guide roll, the air gun having a hollow pin nozzle is mounted at the side of the cylinder, the traction roll is mounted on the forming mechanism, and the cutter is mounted at the side of the traction roll. According to the invention, a given amount of air is filled into the drum-like inner plastic bag to avoid close bonding of plastic films on two sides of the drum-like inner plastic bag under the electrostatic attraction.

Description

technical field [0001] The invention relates to the field of packaging bag manufacturing equipment, in particular to an anti-adsorption processing device for plastic inner bags. Background technique [0002] With the increasing hygienic requirements, most of the paper bags are required to place a cylindrical plastic inner bag to form a composite paper bag structure, so as to avoid the disadvantages of moisture absorption, odor, pollution, etc. after the material contacts with the paper. , when the customer uses it, the vacuum suction cup sucks the paper outside the mouth of the composite paper bag and pulls it to both sides. Since the two outer sides of the cylindrical plastic inner bag are pre-bonded with the two sides of the paper bag, the plastic inner bag The bag is pulled open and the material is filled in the plastic inner bag. [0003] However, since the cylindrical plastic bags are produced at high temperature, the plastic films are tightly bonded due to the attract...

AI Technical Summary

Problems solved by technology

[0003] However, since the cylindrical plastic bags are produced at high temperature, the plastic films are tightly bonded due to the attraction of electrostatic charges. On the customer's automatic filling line, the mechanical equipment often fails when opening, and the Even if the glue between the plastic inner bag and the paper is broken, the plastic bag cannot be opened correctly. This is because the plastic film on both sides is very tightly attached under the attraction of static electricity, and there is almost no air in the middle, which is close to a vacuum state. When the vacuum suction cup When the paper sucked on the outside of the composite paper bag mouth is pulled to both sides, the outside of the plastic inner bag is actually subjected to an atmospheric pressure, and it is impossible for the paper glue to resist, which will lead to the following results: either the bag is pulled from the suction nozzle Pull off, or pull apart the glue that binds the paper and the plastic inner bag, and the material is wrongly filled between the plastic bag and the paper, resulting in filling failure
