[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example Please see Figures 1 to 6The present invention provides a technical solution including a processing pool 1, inside which a pair of conveying rollers 2 are rotatably installed. The conveying rollers 2 are composed of a drive motor 201 and a roller shaft 202. Inside the processing pool 1, a spraying assembly 3 is fixedly installed. Inside the processing pool 1, two drying rods 4 are fixedly installed. One end of each drying rod 4 is connected to an air supply pipe that can deliver hot air to the drying rod 4 and output it toward the tent fabric. Inside the processing pool 1, a winding assembly 5 is rotatably installed at the tail end. The spraying assembly 3 includes a mounting frame 301. Conveying pipes 302 are fixedly installed at the upper and lower ends of the outer side of the mounting frame 301. Several nozzles 303 are fixedly installed on the side of each of the two conveying pipes 302 near the center of the mounting frame 301. The mounting frame 301 is close to the processing pool 301. Two scrapers 304 are slidably mounted on one side of the winding assembly 5 at the tail end of pool 1. Two cam rods 305 are rotatably mounted on one side of the mounting frame 301. A handle 306 is fixedly mounted on one end of each of the two cam rods 305. Magnetic blocks 307 are fixedly mounted on both sides of the mounting frame 301 and both sides of the scrapers 304. The winding assembly 5 includes a winding motor 501. The output end of the winding motor 501 is fixedly connected to a mounting shaft 502. A winding roller 503 is rotatably mounted inside the mounting shaft 502. A limiting block 504 is fixedly mounted inside the tail end of the processing pool 1. A limiting rotating block 505 is rotatably mounted on the top of the limiting block 504. Bolts 506 are threaded onto the bottom of the limiting block 504 and the limiting rotating block 505.

[0020] Specifically, the spray nozzles 303 on the upper and lower sides of the mounting frame 301 can spray functional coatings on both sides of the tarpaulin. Then, the scraper 305 on the side of the mounting frame 301 near the end of the processing tank 1 can smooth the coating on the surface of the tarpaulin, remove excess coating, and ensure that the coating on the surface of the tarpaulin is uniform. Then, the sprayed tarpaulin is quickly dried by the drying rod 4, so as to avoid the coating sticking when rewinding, which would cause uneven coating on the surface of the tarpaulin.

[0021] Please see Figure 2 The mounting bracket 301 has through holes on both the upper and lower sides. The inner diameter of the through holes is equal to the outer diameter of the nozzle 303. The spray nozzle of the nozzle 303 passes through the through holes of the mounting bracket 301 and points to the inside of the mounting bracket 301.

[0022] Specifically, the coating on the tarpaulin surface is achieved through the spray nozzles 303 at both the upper and lower ends of the inner side of the mounting bracket 301.

[0023] Please see Figures 3 to 4 A groove is provided on one side of the mounting bracket 301. The inner surface of the groove is adapted to the outer surfaces of both ends of the scraper 304. The scraper 304 is slidably mounted on the inner side of the mounting bracket 301.

[0024] Both the slide and the scraper 304 have a fixing groove at one end near the center line of the mounting bracket 301. The shape of the fixing groove is adapted to the shape of the magnetic block 307. The magnetic block 307 is fixedly installed in the fixing groove of the mounting bracket 301 and the scraper 304. The magnetic poles of the corresponding surfaces of the two magnetic blocks 307 on the same side of the mounting bracket 301 and the scraper 304 are the same.

[0025] Specifically, by utilizing the magnetic poles of the magnetic block 307 inside the slide groove of the mounting bracket 301 and the magnetic poles of the magnetic block 307 on the scraper 304, the scraper 304 and the mounting bracket 301 generate a repulsive force, which allows the scraper 304 to automatically reset after the pressure is lost.

[0026] Please see Figure 3 A threaded hole is provided on one side of the mounting bracket 301. The inner surface of the threaded hole is adapted to the outer surface of the rotating handle 306. One end of the rotating handle 306 is threaded into the threaded hole of the mounting bracket 301. The cam rod 305 is rotated and installed on one side of the mounting bracket 301 through the cooperation between the rotating handle 306 and the threaded hole.

[0027] Specifically, by using the cam rod 305, rotating the cam rod 305 can cause the cam rod 305 to press the scraper 304 down by different distances.

[0028] Please refer to Figure 5 to Figure 6 A through groove is provided at one end of the mounting shaft 502. The thickness of the through groove is equal to the thickness of one end of the take-up roller 503. The inner surface of the through groove is adapted to the outer surface of one end of the take-up roller 503. One end of the take-up roller 503 is rotatably mounted in the through groove of the mounting shaft 502.

[0029] Specifically, by setting the through groove of the mounting shaft 502, the winding roller 503 can be driven to rotate axially to wind up the tarpaulin without hindering the lateral rotation of the winding roller 503. After the tarpaulin is wound up, it is easy to remove the tarpaulin from the winding roller 503.

[0030] Please see Figures 5 to 6 Both the limiting fixing block 504 and the limiting rotating block 505 are semi-circular. The inner diameter of the circle formed by splicing the limiting fixing block 504 and the limiting rotating block 505 is equal to the outer diameter of one end of the winding roller 503. One end of the winding roller 503 is rotatably installed on the inner side of the limiting fixing block 504 and the limiting rotating block 505.

[0031] The top of the limiting fixing block 504 has a groove, the inner surface of which is adapted to the outer surface of the top of the limiting rotating block 505, and the top of the limiting rotating block 505 is rotatably installed in the top groove of the limiting fixing block 504.

[0032] Both the limiting fixing block 504 and the limiting rotating block 505 have threaded connection holes at their bottoms. The inner surface of the threaded connection hole is adapted to the outer surface of the bolt 506. The limiting rotating block 505 is fixedly installed on one side of the limiting fixing block 504 by the cooperation of the bolt 506 and the threaded connection hole.

[0033] Specifically, the circular shape formed by the splicing of the limiting fixing block 504 and the limiting rotating block 505 can restrict the rotation direction of the take-up roller 503, thereby facilitating the take-up roller 503 to perform the take-up operation.

[0034] In use, the tarpaulin moves from the front end of the processing tank 1 to the rear end via the conveying rollers 2. Upon reaching the spraying assembly 3 area in the middle section of the processing tank 1, the tarpaulin is sprayed by the spray nozzles 303 on both sides of the mounting frame 301 as it passes through the mounting frame 301. The rotating handle 306 controls the cam rod 305 according to the thickness of the functional coating sprayed on the tarpaulin surface, thereby adjusting the distance between the two scrapers 304. The scrapers 304 scrape the coating on the tarpaulin surface as it passes through, ensuring a uniform coating. The evenly coated tarpaulin then... The coating on the tarpaulin surface is quickly set by the heating and drying of the drying rod 4, which prevents the coating from rubbing due to undried coating during the winding process and causing uneven coating on the tarpaulin surface. Finally, the winding motor 501 drives the mounting shaft 502 and the winding roller 503 to rotate, and the winding roller 503 winds up the processed tarpaulin. After winding, the bolt 506 can be removed to rotate the limiting rotating block 505, so that one end of the winding roller 503 can be rotated out of the limiting fixing block 504 and the limiting rotating block 505, making it easy to remove the tarpaulin wound on the winding roller 503.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
