Description

Technical Field

[0001] The utility model relates to the technical field of geomembrane production equipment, in particular to a cooling device used for geomembrane production. Background Art

[0002] Geomembrane is a waterproof barrier material with high molecular polymer as the basic raw material, which is widely used in construction sites. In general, the production of geomembrane uses a screw extruder to plasticize the raw materials of geomembrane, and then forms it through a die. The formed geomembrane is then discharged to the geomembrane roller position and guided out through the roller. Since the temperature of the geomembrane is high when it is discharged from the roller, it is easy to deform. In order to shape the geomembrane, the geomembrane needs to be cooled.

[0003] Existing geomembrane cooling devices generally use air cooling, using cooling air to blow to the upper and lower surfaces of the moving geomembrane to directly cool its surface. However, the geomembrane is relatively thin and has a large area. When the air is blown for cooling, the upper and lower parts of the geomembrane are subjected to moving pressure. Once the upper and lower forces are uneven, the geomembrane will shake, affecting the transmission of the geomembrane, and it is very likely to cause transmission deviation and wrinkles. In addition, the current cooling effect is average and needs to be improved. Utility Model Content
