[0039] The other end of the bracket 2 is symmetrically and fixedly connected to a winding frame 20, and the end of the winding frame 20 is rotatably connected to a winding roller 21;
[0040] It should be noted that, in use, the geomembrane spraying device uses the unwinding roller 16 in conjunction with the unwinding frame 15 to unwind the geomembrane, while the take-up roller 21 in conjunction with the take-up frame 20 to take up the geomembrane. A feed pipe is connected to the three-way connector 6 to deliver liquid spraying material to the inside of the connecting pipe 4 and spray it out through the nozzle 5 to spray both sides of the geomembrane. A servo motor 12 on the scraper assembly is connected to an external control device, which sets a suitable forward and reverse rotation program for the servo motor 12. The power output of the servo motor 12 drives the double-headed screw 10 to rotate, thereby using the connecting seat 11 to move the guide blocks 9 in opposite directions. This allows adjustment of the spacing between the blades of the scraper 13 according to the thickness of the sprayed coating. The scraper 13 removes excess coating from the geomembrane, ensuring uniform distribution of the coating and guaranteeing the quality of the geomembrane spraying.

[0047] like Figure 1As shown, multiple nozzles 5 are equidistantly arranged at the axial position of the connecting pipe 4;
[0048] It should be noted that this ensures uniformity during the geomembrane roughening process.
[0049] like Figure 2 As shown, the blades of the two symmetrically arranged scrapers 13 correspond to each other;
[0050] It should be noted that the spacing between the blades of the scraper 13 can be adjusted according to the thickness of the coating. The scraper 13 can be used to scrape off excess coating on the geomembrane, thereby ensuring the uniformity of coating distribution on the geomembrane.
[0051] In use: the unwinding roller 16, in conjunction with the unwinding frame 15, unwinds the geomembrane, while the winding roller 21, in conjunction with the winding frame 20, winds the geomembrane.

The servo motor 12 on the scraper assembly is connected to an external control device, and a suitable forward and reverse rotation program is set for the servo motor 12. The double-headed screw 10 is driven to rotate through the power output end of the servo motor 12, thereby driving the guide block 9 to move in opposite directions via the connecting seat 11. The spacing between the blades of the scraper 13 can be adjusted according to the thickness of the coating, and the scraper 13 scrapes off the excess coating on the geomembrane.
