A kind of plastic film processing equipment

Abstract

The invention provides plastic film processing equipment. The plastic film processing equipment comprises a film blowing mechanism, a traction mechanism, a winding mechanism and a plurality of extrusion mechanisms, wherein the film blowing mechanism comprises a die head, an air ring and a rack, multiple layers of runners are arranged in the die head, and the runner on each layer is connected with one extrusion mechanism; the air ring is arranged on the die head, the air ring is provided with uniformly-distributed air inlet ports, the air inlet ports are connected with air inlet tubes, a corona machine is arranged above the air ring, and a fixed mandrel is vertically arranged at the centre of the air ring; and the die head and the air ring are fixedly arranged at the lower end of the rack, the traction mechanism is arranged between the film blowing mechanism and the winding mechanism, and plastic films blown from the die head are transmitted to the winding mechanism by the traction mechanism. The plastic film processing equipment provided by the invention is compact in structure, and capable of increasing the yield of the plastic films.

Description

technical field [0001] The invention belongs to the technical field of plastic films and relates to a plastic film processing equipment. Background technique [0002] The production of film mainly adopts a blown film machine. The raw material is heated into a molten state through the extrusion mechanism and extruded, and the film bubble is blown out by compressed air to make a film, and then the film is sent to the winding mechanism through the traction mechanism, and the winding mechanism will The film is rolled into a roll. [0003] When the film involves a variety of raw materials, due to the different properties of each raw material, it is necessary to consider that the heating temperature and heating time are different. This production situation is bound to expand the structure of the film blowing machine, so how to use it in a limited production space? Making the structure of the blown film machine more compact is also a problem in film production. [0004] In the ex...

AI Technical Summary

Problems solved by technology

[0004] In the existing film production, there are still the following problems. The processing of raw materials affects the product quality of the film. All raw materials entering the extrusion mechanism must completely remove moisture and dust, so the raw materials need to be dried and crystallized in the early stage.

However, the drying and crystallization process in the early stage is relatively large, and uneven drying is prone to occur, and the process of raw materials being transported to the extrusion mechanism is easily affected by the surrounding environment and damp

[0005] Secondly, the film is prone to offset during traction and winding, which will cause the film to fold and produce wrinkles, and there will be a large misalignment between the upper and lower layers of the film roll, which will affect the product quality of the film.
