Film blowing machine with edge pressing function for medicine heat-seal packaging

Abstract

The invention relates to the related field of film blowing machines. The invention discloses a film blowing machine with an edge pressing function for medicine heat-seal packaging and aims at solving the problems that in the stretching process of a film body, wrinkles are likely to happen, a device cannot conduct quantitative medicine feeding conveniently, and the device cannot cut packaged medicine bags conveniently. The film blowing machine is composed of a cutting mechanism, a pressing mechanism and a feeding mechanism. According to the film blowing machine with the edge pressing function for medicine heat-seal packaging, a motor is matched with a transmission belt to drive a rotating rod to rotate, then the rotating rod is matched with the transmission belt to drive a lower side transmission roller to rotate clockwise when rotating, the lower side transmission roller is matched with a rotating gear to drive an upper side transmission roller to rotate anticlockwise, and the two transmission rollers are promoted to stably convey the film body; and when the lower side transmission roller rotates clockwise, the lower side transmission roller is matched with the belt to drive two reciprocating lead screws to rotate, then spiral blades on the side faces of the reciprocating lead screws are promoted to rotate to spread the film body towards the two sides, and the possibility that wrinkles occur on the surface of the film body is reduced.

Description

technical field [0001] The invention relates to the related field of film blowing machines, in particular to a film blowing machine for heat-sealing packaging of medicines with the function of crimping. Background technique [0002] Blown film is a plastic processing method, which refers to the molten material plasticized by the barrel of the extruder, which is extruded into a cylindrical film blank through a molding die, and then blows air with a certain pressure into the barrel to blow the round film. The plastic of the tubular film blank is inflated to reach the diameter and thickness of the film tube required for production, and is cooled and shaped into a film product. This kind of blown film is generally produced by polyethylene, polypropylene and polyvinyl chloride resin. The color of the film formed by blown film is uniform and clean, and the finished product is stretched well. [0003] Some existing film blowing machines for heat-sealing packaging of medicines, be...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a film blowing machine for medicine heat-sealing packaging with the function of crimping, to solve the above-mentioned background technology: when the device is stretching the film body, the film body is wrinkled in the transverse direction, which easily affects the device. The effect on drug packaging, when the device is packaging the drug, it is necessary to manually put the drug into the packaging bag quantitatively, and then package it. The operation is more troublesome. Cutting the medicine package, the work procedure is more complicated
