Plastic film blowing machine and film blowing process thereof

Abstract

The invention discloses a plastic film blowing machine and a film blowing process thereof. The plastic film blowing machine comprises a bottom plate; a supporting table is fixedly arranged on one side of the upper end of the bottom plate; a forming table is fixedly arranged at the upper end of the supporting table; an air outlet ring is fixedly arranged at the upper end of the forming table; a discharging ring opening is fixedly formed in the position, on the outer side of the air outlet ring, of the upper end of the forming table; an air return pipe is fixedly arranged in the middle of the upper end of the forming table; a first mounting base is fixedly arranged at the position, on one side of the supporting table, of the upper end of the bottom plate; a first air pump is fixedly arranged at the upper end of the first mounting base; a first ventilation pipe is fixedly arranged at the upper end of the first air pump; and the first ventilation pipe is fixedly connected with the air outlet ring. The plastic film blowing machine is good in using effect, the size of a discharging opening of the discharging ring opening can be changed conveniently, so that the material spraying pressure of the device can be changed conveniently, meanwhile, the diameter of a limiting mechanism of the device is convenient to adjust, and therefore plastic films with different widths can be extended conveniently.

Description

technical field [0001] The invention relates to the technical field of film blowing machines, in particular to a plastic film blowing machine and a film blowing process thereof. Background technique [0002] The film blowing machine heats and melts plastic particles and blows them into films. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand-new particles, the color is uniform, clean, and the bag stretches well. [0003] However, the current blown film machines have the following disadvantages when they are in use: [0004] 1. The diameter of the film blown out by the film blowing machine is not easy to adjust, so it is not easy to change the width of the film after forming; [0005] 2. The size of the mold outlet of the film blowing machine cannot be adjusted, so that it is impossible to change the injection pressure of the device under the condition of inconvenient material flow, so that it cannot ada...

AI Technical Summary

Problems solved by technology

[0004] 1. The diameter of the film blown out by the film blowing machine is not easy to adjust, so it is not easy to change the width of the film after forming;

[0005] 2. The size of the mold outlet of the film blowing machine cannot be adjusted, so that it is impossible to change the injection pressure of the device under the condition of inconvenient material flow, so that it cannot adapt to the film with different diameters and thicknesses;

[0006] 3. The film material of the current film blowing machine often needs to be stored by the winding drum after being formed, and the winding drum cannot be replaced quickly after collecting the full film, which will affect the processing efficiency of the device
