Description

Heating structure for film blowing machine Technical Field The utility model relates to the technical field of film blowing machines, in particular to a heating structure for a film blowing machine. Background A film blowing machine is a special device for blowing plastic particles into a film after heating and melting, and the principle is that the plastic particles are melted by an extruder, then a tubular blank is extruded by a die head, and then the tubular blank is formed by compressed air inflation and cooling to form the film. The existing film blowing machine mainly comprises an extruder system, a die head system, a cooling device, a traction mechanism and the like, wherein a feeding end of the extruder system is generally fed through an open feeding hopper structure, a plastic particle heating device is connected between the feeding hopper and an extrusion screw cylinder, the heating device mainly heats a feeding pipe by utilizing electric heating pipes and electric resistance heating, and then heats plastic particles in the feeding pipe, finally molten liquid plastic is obtained, the liquid plastic flows into the extrusion screw cylinder and is extruded into the die head system, but after the feeding is heated, the liquid plastic has viscosity in the extrusion and downward flowing process of the granular plastic in the feeding hopper, so that the liquid plastic moves down into the extrusion screw cylinder in a pipeline of the heating device very slowly, and finally the feeding efficiency of the extruder system is low. Disclosure of utility model The utility model provides a heating structure for a film blowing machine, which aims to solve the problem that the feeding efficiency is affected because the existing process that liquid plastic moves downwards in a pipeline of a heating device and enters an extrusion screw cylinder is slow.
