Cooling device for plastic film and application thereof

Abstract

The invention provides a cooling device for a plastic film and application thereof. The cooling device comprises a crushing and feeding unit, a heating unit, an extrusion unit, a first cooling wind ring, a second cooling wind ring, a herringbone clamping plate and a rolling unit, wherein the crushing and feeding unit is connected with the extrusion unit via the heating unit; the first cooling wind ring is arranged out of the extrusion unit; the second cooling wind ring is arranged below the herringbone clamping plate; and the rolling unit is connected with herringbone clamping plate via a rolling roller train. The cooling device has the beneficial effects that one wind ring is used for cooling molding above a die orifice, and the other set of wind ring is additionally arranged below the herringbone clamping plate to allow a molded film to be fully cooled below the herringbone clamping plate.

Description

technical field [0001] The invention relates to the technical field of plastic molding machinery, more specifically, to a plastic film 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
