Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a temperature-controllable raw material mixing and heating structure for film blowing machines. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into thin films. There are many types of film blowing machines, including PE, POF, PVC, etc. The new materials blown out with brand new particles are new materials with uniform color, clean and good bag stretching. However, many film blowing machines on the market have single functions, lack temperature control measures, and lack of mixing uniformity, which affects the subsequent production quality. Therefore, a functional raw material mixing and heating structure is indispensable for the production operation of film blowing machines.

However, the structure of this utility model is relatively complicated, and secondary stirring is required to ensure the uniformity of the raw materials, which is not convenient for ensuring production efficiency. For this reason, we propose a temperature-controllable raw material mixing and heating structure for film blowing machines, which improves the structural form of the stirring device, solves the problem of uneven primary stirring of the raw materials, and improves the practical effect of the structure.
