Film blowing machine capable of being adjusted according to specific production conditions and method

Abstract

The invention relates to the technical field of film blowing, and discloses a film blowing machine capable of being adjusted according to the specific production situation and a method. The film blowing machine comprises a shell, a trigger mechanism is movably connected in the shell, an air cavity is formed in the right end of the trigger mechanism and located in the shell, an air outlet hole is formed in the upper end of the air cavity and located in the upper end of the shell, a driving rod is movably connected to the interior of the shell, a transmission mechanism is fixedly connected to the bottom of the driving rod, and an adjusting mechanism is movably connected to the bottom of the transmission mechanism. A bearing plate drives a pressure adjusting block to move towards the bottom of the shell, so that the distance between the pressure adjusting block and a flow guide block is shortened, extrusion force is applied to the interior of the flow guide block, the pressure intensity in the flow guide block is enhanced in a short time, the flow speed in the flow guide block is increased, the thickness of a film at the upper end of the flow guide block is increased, and therefore, an effect of automatically correcting the film is achieved when the thickness of the film is not uniform due to equipment.

Description

technical field [0001] The invention relates to the technical field of blow molding machines, in particular to a film blow molding machine and a method that can be adjusted according to specific production conditions. Background technique [0002] With the modern industrial production, the modern industry generally uses equipment to process the required materials during production, which can save a lot of labor, such as film blowing machines, which can produce a large number of films with only a small number of workers, and the efficiency is greatly improved. improve. [0003] However, at present, when the film is extruded by the extruder for stretching during the film blowing process, sometimes the thickness of the film during the stretching process is thinner due to the decrease in the internal pressure, and it is easy to cause the film to be stretched and torn during stretching, or The tensile quality is not enough, the toughness is not enough, and at the same time, when...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a film blowing machine and method that can be adjusted according to specific production conditions, and is capable of automatically correcting the film when the thickness of the film is uneven due to equipment, and at the same time adjusting the thickness of the film as the tightness of the film Weaken to prevent the film from being broken due to excessive wind force due to the decrease in film thickness. It solves the current problem of stretching due to the decrease in internal pressure when the film is extruded by the extruder in the film blowing process. During the stretching process, the film thickness is relatively thin, and it is easy to cause the film to be stretched and torn during stretching, or the stretching quality is not enough, and the toughness is not enough. Thin, it is easy to cause the problem of excessive internal volume and uneven thickness during blow molding
