Description

Winding mechanism of geotextile film coating machine

Technical Field

Background

The composite plastic woven cloth has been produced in China for decades, and the used raw materials mainly comprise polypropylene, polyethylene and ethylene-vinyl acetate copolymer. The production process flow is that polypropylene or low-pressure polyethylene is extruded into film on a wire drawing machine, and is cut into flat wires by a dense blade, and the flat wires are wound into wire ingots after being heated, stretched and shaped by heat treatment; the flat filaments are woven into plastic woven cloth by a weaving machine such as a circular weaving machine, a water weaving machine or a projectile weaving machine, and then one side or two sides of the plastic woven cloth are coated with polymer materials such as polypropylene, high-pressure polyethylene or ethylene-vinyl acetate copolymer in a flow casting way by a plastic extrusion film coating machine.

The composite plastic woven cloth has the advantages of water resistance, no toxicity, light weight, good low temperature resistance, easy recycling and the like, and is widely applied. The composite plastic woven cloth is mainly applied to geotechnical seepage prevention, tents, color strip cloth, tarpaulin, plastic greenhouses, aquaculture, roof heat preservation layers, PE advertisement cloth, electric heating carpet lining cloth, vegetable greenhouse heat preservation quilts and the like, so the composite plastic woven cloth is also called geotechnical cloth.

In order to improve the automation degree of the production of the geotextile, a double-station winding device is generally adopted for winding after the production of the geotextile.

However, when the width of the geotextile is too large, for example, the geotextile in Xinjiang has a width of 4 m, the original four-roller friction winding double-station winding machine can not adapt to the production requirement gradually, and the reasons include two aspects: firstly, double-station coiling requires a paper tube as a core tube, a steel core shaft penetrates into the core tube, and when the coil is changed, the steel core shaft must be taken out and then penetrates into a new paper core tube, so that the labor intensity of workers is increased, meanwhile, the paper tube improves the production cost, and the construction site is polluted by waste paper tubes; and secondly, the composite membrane and the smooth sheet of the geotextile are required to be thicker and thicker, the thickness usually reaches 0.5-0.6 MM and sometimes reaches 1MM, and for a screw with a certain yield, the linear speed of the film laminating machine is usually about 5-10M/MIN, and the linear speed is slow, so that double-station winding can be completely replaced by a single station, and the non-stop roll change can be realized under the condition of not using a cloth storage device, so that the equipment cost is reduced.
