Film blowing machine for biodegradable environment-friendly express bag production

Abstract

The biodegradable environment-friendly express bag production film blowing machine comprises a feeding mechanism and a fixed base, the lower end of the feeding mechanism is installed on one side of the upper end of a heating conveying mechanism, and one side of the heating conveying mechanism penetrates through the lower end of a protection frame through a discharging pipe to be connected with an extrusion molding die head; the film blowing machine for biodegradable environment-friendly express bag production is provided with a feeding mechanism and a stirring device, through the feeding mechanism, plastic particles can be conveniently stored and discharged, the stirring device is arranged on the side, away from the supporting frame, of the upper end of the fixing base, the stirring device is arranged on the side, away from the supporting frame, of the lower end of the fixing base, and the cooling limiting mechanism is arranged; the plastic particles stored in the discharging hopper can be conveniently stirred through the stirring device, so that the plastic particles can be rapidly discharged under the stirring of the stirring rod, and the plastic particles in the discharging hopper are prevented from being tightly extruded to block the joint of the discharging hopper and the discharging pipe; and the problem of difficult blanking is solved.

Description

technical field [0001] The invention relates to the technical field of film blowing machines, in particular to a film blowing machine for producing biodegradable environment-friendly express bags. Background technique [0002] Express bags refer to the bags used in the express industry to transport documents, documents, materials, goods and other packaging. Widely used in logistics systems to play the role of waterproof, dustproof, moisture-proof, etc. Express bags are generally made of plastic film, and plastic film can be produced by a plastic blown film device, which is equipped with a plastic extruder and extruded Die head, the extrusion die head is provided with a circular extrusion port, a herringbone splint is arranged above the extrusion die head, and a traction nip roller is fixed above the herringbone splint. During production, the high-temperature molten resin material is extruded by extrusion After being extruded from the circular extrusion port of the die head,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a biodegradable film blowing machine for the production of environmentally friendly express bags, so as to solve the disadvantages of the feeding mechanism in the film blowing machine proposed in the above-mentioned background technology. When feeding and discharging, it is easy to cause the plastic particles inside the discharge hopper to be squeezed tightly due to excessive pouring, which will block the connection between the discharge hopper and the discharge pipe, affecting the discharge, and it is impossible to stabilize and limit the film bubbles of different diameters. It is inconvenient to replace the winding drum, the operation is complicated, time-consuming and labor-intensive
