Film winding and cooling device and application thereof

Abstract

The invention provides a film winding and cooling device and an application thereof. A smashing and charging device is connected with an extruding device through a heating device; a cooling air ring is movably arranged between the extruding device and a herringbone splint and is connected with an air ring lifting device; a winding device is connected with the herringbone splint through a winding roller group; a center shaft is provided with a winding roller support and a supporting roller support; the winding roller support is provided with winding rollers; the supporting roller support is provided with guide rollers; rotating arm shafts are arranged on positions, close to the winding rollers, of the winding roller support; each rotating arm shaft is provided with a rotating arm; the front end of each rotating arm is provided with a pressing roller shaft; the pressing roller shaft is provided with a rubber pressing roller; and the rubber pressing rollers press against the winding rollers. Due to the arrangement of the cooling air ring capable of lifting, a film can be continuously and sufficiently cooled after being molded in the process that the plastic film required to be cooled is cooled in real time, so that the condition of poor opening performance of the film is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic molding machinery, more specifically, to a film winding cooling device and its application. Background technique [0002] Blowing film (Blow Membrane) is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film. If it is a film blown out of new materials, the color is uniform and clean, and the finished product is stretched well. If the plastic particles made of recycled waste plastics are usually added with pigments when made into a film, the resulting film may be unevenly colored, brittle and easily broken, and the price is relatively low. The blown film materials produced by professional film blowing machines are suitable for various high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture resistance, f...

AI Technical Summary

Problems solved by technology

[0003] Due to the high humidity of the film coming out of the film blowing machine, and the process often squeezes two or more layers of film together, when the ambient humidity is not high, it does not have much impact on the later layered cutting, but when When the ambient humidity is high, due to the characteristics of the plastic film, when the extruded multi-layer film is to be cut in layers, it is often difficult to separate due to the film sticking together. Currently, there are often no suitable blown film equipment on the market. Cooling equipment, so in summer production, it is often necessary to waste a lot of electricity for overall cooling of the workshop

In the accessories of film blowing machine, there is no convenient, practical and low-cost cooling equipment
