Description

Technical Field

[0001] The utility model relates to the technical field of bubble extrusion, in particular to a bubble extrusion mechanism for producing and processing geomembranes. Background Art

[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and composited with non-woven fabrics. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), and EVA (ethylene / vinyl acetate copolymer). In tunnel applications, there are also designs for using ECB (ethylene vinyl acetate modified asphalt blended geomembranes). They are a kind of polymer chemical flexible material with a small specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low temperature resistance, and good antifreeze performance. In the production process of geomembranes, bubble extrusion equipment is needed to process the geomembrane to avoid the presence of bubbles in the geomembrane, which affects the production quality of the geomembrane.

[0003] A bubble roller extrusion mechanism disclosed in the Chinese patent announcement with the announcement number CN205326101U is found. Its technical points are: it includes a rotating roller, a fixed roller, a roller body, and the surface of the roller body is provided with a silicone layer and a carbon nanotube film. A fixed roller is provided at the bottom of the rotating roller. The rotating roller and the fixed roller include a roller body, a roller shaft, a fixing device, a groove and an oil filling hole. Grooves and fixing devices are symmetrically provided at both ends of the roller body. The roller body is connected to the roller shaft. A groove is provided on the outer wall of the fixing device. A silicone layer and a carbon nanotube film are provided on the roller body. A crystal membrane is provided between the rotating roller and the fixed roller. The inside of the silicone layer is carbon fiber, and a PFA tube is provided on its surface. The material of the roller body is iron, and a silicone layer is provided on the outer surface of the roller body. The silicone layer is coated with a carbon nanotube film. The outside of the roller shaft is connected to a motor. The center of the roller body is the roller shaft. Oiling is provided on both sides of the roller shaft. The groove is arc-shaped, and a wear-resistant layer of alloy material is provided in the groove. The oil filling hole is circular or elliptical.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: the device can only perform a bubble extrusion operation on the geomembrane when the geomembrane passes through. There is a situation where the bubbles have not been completely extruded and the geomembrane has already separated from the rotating roller, and the bubble extrusion efficiency is poor. For this reason, we propose a bubble extrusion mechanism for geomembrane production and processing to solve the above problems. Utility Model Content
