Bag-making device for plastic packaging film

Abstract

The invention discloses a bag making device for plastic packaging films. The bag making device structurally comprises a base, a support, a longitudinal adjustment support, a plastic bag cutter, cutting mold tools, a plastic-pressing conveying roller, a driving conveying roller and a motor. The plastic-pressing conveying roller is composed of a shaft rod, a pressing ring adjustment mechanism, a magnetic pressing ring and a dedusting roller. The bag making device has the effects that through the cooperation of the plastic-pressing conveying roller and the driving conveying roller, plastic filmscan be positioned when conveyed so as to be prevented from contracting towards the center of the roller or expanding towards the two sides of the roller; and the situation that the surfaces of the plastic films cannot completely make contact with the roller due to compressive contact between the plastic films and dust in the conveying process, the stress applied to the surfaces of the plastic films is not uniform, deformation of the plastic films is caused, and plastic bags made from the plastic films are wrinkled is avoided.

Description

technical field [0001] The invention relates to the field of equipment for plastic packaging products, in particular to a bag-making device for plastic packaging films. Background technique [0002] Now the packaging bag market is getting better and better, because no matter what kind of goods are inseparable from the packaging of packaging bags, while the packaging bag market is developing, the quality requirements for packaging bags in the market are also getting higher and higher. Plastic bag making machine In the process of production, because the plastic film is relatively thin, plastic bags are prone to wrinkles, which will seriously affect the aesthetics and quality of the finished plastic bags. The main reasons for the wrinkles of plastic bags are as follows : [0003] 1. The pressure of the rubber roller in the middle of the plastic bag making machine is not uniform, it is difficult to locate the plastic film in the conveying process, and it is easy to make the pla...

AI Technical Summary

Problems solved by technology

[0003] 1. The pressure of the rubber roller in the middle of the plastic bag making machine is uneven, and it is difficult to locate the plastic film in the conveying process. It is easy to make the plastic film shrink toward the center of the rubber roller or expand to both sides, resulting in deformation of the plastic film and making the manufactured plastic bag have wrinkle problem;

[0004] 2. There is too much dust on the rubber roller of the bag making machine, which makes the plastic film in the transportation contact with the dust oppressively, which makes the surface of the plastic film unable to completely contact with the rubber roller, which makes the surface of the plastic film uneven, resulting in deformation of the plastic film , so that the manufactured plastic bags have the problem of wrinkling
