Film blowing and heat sealing integrated machine

Abstract

The invention relates to a film blowing and heat sealing integrated machine which comprises a film blowing machine body, wherein the film blowing machine body comprises an extruder, a filtering device, a die head, an air ring, a mandrel, a herringbone plate and a first draft gear; the die head is arranged at the extruding end of the extruder, the air ring is arranged on the die head, the mandrel is coaxially arranged in the middle of the die head, the herringbone plate is arranged above the mandrel, and the first draft gear is arranged above the herringbone plate; and the integrated machine also comprises a heat sealing machine body, wherein the heat sealing machine body comprises a second draft device and a heat sealing roll assembly, the second draft device is used for carrying out second time of traction on a film pulled by the first draft device, and the heat sealing roll assembly is used for carrying out heat sealing on the film pulled by the second draft device. The integrated machine has the advantages that occupation area is small, manufacture cost is low, maintenance rate is low, heat sealing stationarity is good, noise is low, and a prepared film bag is convenient to take and easy to open.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a blown film heat bonding machine. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of polyester film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Films are widely used in electronics, machinery, printing and other industries. [0003] The production process of the film bag includes the following steps: 1) Make the resin masterbatch into a film through a film blowing machine; (2) Wind it up with a winding machine and cut it to a set length through a cutting machine; (3) Use a heat sealing machine Carry out heat sealing; (4) Cut out the film bag that bottom edge heat seals, both sides seals, top opening. ...

AI Technical Summary

Problems solved by technology

The equipment occupies a large area, the cost is high, and the production efficiency is low

[0005] The traditional heat sealing machine is a downward-pressing heat-sealing device, and the downward-pressing heat-sealing device performs a downward movement for a long time, which will fail and require frequent maintenance

Moreover, in the process of heat sealing under pressure, a certain amount of stamping is caused to the film, and the stability of heat sealing needs to be improved.

In addition, the press-type heat sealing machine is noisy when it is working.

[0006] The film bag made by heat-sealing and cutting of the traditional film has the shape of the opening, which is inconvenient to carry after installing the article; in addition, this kind of film bag is not easy to open
