Plastic film absorbing, winding and cooling device and application thereof

Abstract

The invention provides a plastic film absorbing, winding and cooling device and application thereof. A crushing and feeding device is connected with an extruding device through a heating device; a first cooling wind ring is arranged out of the extruding device; a second cooling wind ring is arranged below a herringbone clamping plate; a winding device is connected with the herringbone clamping plate through a winding roller set; a winding roller bracket and a support roller bracket are movably arranged on a center shaft of the winding device; winding rollers are arranged at two ends of the winding roller bracket; support rollers are arranged at two ends of the support roller bracket; a guide roller is arranged on the support roller bracket; the winding rollers adopt hollow structures; absorbing devices are arranged in the winding rollers; absorbing through holes are uniformly formed in the winding rollers; absorbing sleeves are arranged on the outer sides of the winding rollers; and the absorbing devices are connected with negative-pressure generation devices through pipelines. The wind rings are used for cooling formation above a die orifice; a set of wind ring is added below the herringbone clamping plate for fully cooling a formed film continuously below the herringbone clamping plate; and the winding device is convenient for use and convenient to replace the winding rollers, and has the absorbing effect.

Description

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

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
