Problems solved by technology

[0005] In the above prior art, when the connecting rod and the hot blast nozzle are hinged, there is a gap between the connecting rod and the hot blast nozzle which facilitates the swing of the hot blast nozzle, so that the hot blast nozzle cannot completely swing with the moving range of the connecting rod during the swing process. Instead, there will be a certain degree of free shaking during the swing process, which will easily cause the swing range of adjacent hot air nozzles to overlap, so that the material sprayed by the roughening device on the geomembrane is not uniform enough

The pressure roll...

Embodiment 2

[0104] refer to Figure 11 , is a secondary roughening device disclosed in this embodiment and the production line of the rough surface geomembrane. The difference between this embodiment and Embodiment 1 is that the frame 51 is fixed below the upper shelf plate 511 The lower shelf 512, the upper shelf 511 and the lower shelf 512 are respectively provided with the roughening mechanism 53 in Embodiment 1, so that the roughening device in this embodiment forms two rows of roughening stations up and down, and the upper shelf 511 The roughening mechanism 53 on the top is close to the film storage device 4 , and the roughening mechanism 53 on the lower shelf 512 is close to the winding device 6 . A reversing roller 513 is provided on the side of the frame 51 close to the winding device 6 , and both ends of the reversing roller 513 in the length direction are connected to the frame 51 in rotation.

[0105] The implementation principle of this embodiment is: when the sheet-shaped ge...

Embodiment 3

[0108] refer to Figure 12 The difference between this embodiment and Embodiment 2 is that the roughening outer tubes 7 are movably socketed on the outer peripheral surfaces of all the roughening tubes 531 , and the roughening outer tubes 7 are located below the high-pressure hot air pipe 532 . On the frame 51, a stroke rail 8 is fixed on the side near the second screw extruder 52 of the roughened outer pipe 7, and the stroke rail 8 extends along the length direction of the frame 51, and the upper shelf plate 511 and the lower shelf plate 512 Corresponding positions are all provided with this travel rail 8.

[0109] refer to Figure 13 One end of the travel rail 8 facing the spray pipe 531 is provided with a sliding groove 81 , and the sliding groove 81 extends along the length direction of the travel rail 8 . The outer periphery of each rough spraying outer tube 7 is connected with a slide bar 71 to rotate toward the side of the sliding groove 81, and the end of the sliding...

Abstract

The invention relates to a secondary spray roughing device, and a production line and process for a textured geomembrane. The secondary spray roughing device comprises a rack, an extrusion die head, aswing mechanism and a spray roughing mechanism, and the spray roughing mechanism is rotatably connected and communicates with the extrusion die head; the spray roughing mechanism is driven by the swing mechanism to swing; the spray roughing mechanism is provided with an elastic piece, and one end of the elastic piece is connected with the spray roughing mechanism; the other end of the elastic piece is connected with the rack; the production line for the textured geomembrane is provided with a plate extruding device, a calendering device, a transmission device, a geomembrane storage device, the secondary spray roughing device and a winding device; and the production process for the textured geomembrane comprises the steps of ingredient mixing, extrusion, calendering, transfer, geomembranestorage, online secondary spray roughing, winding and cutoff. According to the secondary spray roughing device, and the production line and process for the textured geomembrane, the online spray-coating and secondary spray roughing can be achieved on the production line for the geomembrane; not only can the shortcomings of poor adhesion force and small friction coefficient of spray roughing materials on the geomembrane surface can be avoided, but also the effects of one-step forming and uniform textured surfaces of a geomembrane product with a single textured surface or double textured surfaces can be achieved.

Description

technical field [0001] The invention relates to the technical field of rough geomembrane production, in particular to a production connection line and process of a secondary roughening device and rough geomembrane. Background technique [0002] Geomembrane is a polymer chemical flexible material mainly produced based on polyvinyl chloride (PVC), polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), etc. It has excellent waterproof and barrier properties and is widely used as an anti-seepage material. It is used in building construction, road construction, bridge construction and other engineering construction. According to the shape of the product, geomembrane can be divided into smooth geomembrane and rough geomembrane. Compared with smooth geomembrane, the surface of rough geomembrane is rougher, so the coefficient of friction is higher. It is suitable for steep slope construction, mountainous area construction and other engineering projects. It is the preferred mate...
