[0028] The guide roller 5 is driven by a motor to rotate, so that the PE film is moved. At this time, under the rotation of the coating roller 4, the glue in the inner cavity of the fixed box 2 is evenly smeared on the lower surface of the PE film, and then under the action of the scraping mechanism 3 on the right side of the coating roller 4, the excess glue on the lower surface and side of the PE film is removed, and the scraped excess glue falls downward into the inner cavity of the fixed box 2, so that it is smeared and used under the action of the coating roller 4.

[0029] like Figure 2 As shown, a coating glue tank 21 is fixedly connected to the bottom of the inner cavity of the left part of the fixed box 2, the inner wall of the coating glue tank 21 is arc-shaped, and the lower half of the coating roller 4 is located in the inner wall of the coating glue tank 21;

[0030] Through the effect of the coating glue groove 21, the coating roller 4 can carry the glue evenly without generating dead corners, thereby preventing corner waste and facilitating cleaning of the interior after use.

[0032] Through the action of the guide inclined plate 22, the glue scraped off by the scraper plate 34 and the scraper block 355 can flow into the inner cavity of the glue coating tank 21, thereby preventing waste and improving utilization.

[0033] like Figure 3 , Figure 4 As shown, the scraping mechanism 3 includes a U-shaped support plate 31, the lower surface of the U-shaped support plate 31 is fixedly connected to the upper surface of the right part of the fixed box 2, the front and rear parts of the upper surface of the U-shaped support plate 31 are fixedly connected with two symmetrical adjustment components 33, the opposite surfaces of the upper parts of the two adjustment components 33 are fixedly connected with a connecting cross plate 32, and the connecting cross plate 32 is located above the U-shaped support plate 31, the opposite surfaces of the lower parts of the two adjustment components 33 are fixedly connected with a scraping plate 34, and the scraping plate 34 is located inside the U-shaped support plate 31, and the inner cavity of the U-shaped support plate 31 is fixedly installed with a side scraping component 35, and the side scraping component 35 is fixedly installed with a side scraping component 35. The lower part of the assembly 35 is located on the left side of the scraper plate 34; the adjustment assembly 33 includes a hydraulic rod 331, the output end of the hydraulic rod 331 is fixedly connected to a connecting slide 332, the side of the connecting slide 332 close to the scraper plate 34 is fixedly connected to the side of the connecting cross plate 32 close to the hydraulic rod 331, the side of the connecting slide 332 away from the connecting cross plate 32 is fixedly connected to a connecting rod 334, the outer wall of the lower part of the connecting rod 334 is movably sleeved with the inner cavity of the U-shaped support plate 31, and the side of the lower part of the connecting rod 334 close to the connecting cross plate 32 is fixedly connected to the side of the scraper plate 34 close to the hydraulic rod 331;

[0034] Through the action of the hydraulic rod 331, the connecting slide plate 332 drives the connecting rod 334 to move upward under the action of the guide slide rod 333, so that the scraper plate 34 below moves upward to the lower surface of the PE film. When the PE film moves, the excess glue on the lower surface of the PE film is scraped off, so that it is convenient to adjust the scraper according to the thickness of the PE film.

[0035] The inner cavity of the connecting slide plate 332 is movably sleeved with a guide slide bar 333, driving the lower surface of the guide slide bar 333 to be fixedly connected with the upper surface of the U-shaped support plate 31;

[0036] Through the action of the guide slide bar 333, the two connecting rods 334 can stably drive the scraper plate 34 to move horizontally, thereby ensuring that the upper surface of the scraper plate 34 and the lower surface of the PE film are located on the same horizontal line.

[0037] like Figure 5 , Figure 6As shown, the side scraper assembly 35 includes a motor 351, the outer wall of the motor 351 is fixedly connected to the inner cavity of the front part of the U-shaped support plate 31, the output end of the motor 351 is fixedly connected to a threaded rod 352 and the threaded rod 352 is located between the connecting cross plate 32 and the scraper plate 34, the outer walls of the front and rear parts of the threaded rod 352 are respectively movably sleeved with the inner cavity of the U-shaped support plate 31, the front and rear parts of the middle outer wall of the threaded rod 352 are both threadedly sleeved with sliders 354, the outer walls of the two sliders 354 are respectively movably sleeved with the inner cavity of the U-shaped support plate 31, and the opposite surfaces of the lower parts of the two sliders 354 are fixedly connected with scraper blocks 355;

[0038] The threaded rod 352 is rotated by the action of the motor 351. Since the threads of the outer walls of the front and rear parts of the middle part of the threaded rod 352 are opposite, the two sliders 354 are moved toward each other under the action of the guide rod 353, so that the two scraping blocks 355 move toward each other. By adjusting the positions of the two scraping blocks 355, the two scraping blocks 355 can scrape glue on the front and rear sides of the PE film, so that the scraping glue can be adjusted according to the width of the PE film, which is convenient for use.

[0039] The inner cavities of the left and right parts of the upper parts of the two sliders 354 are movably sleeved with guide rods 353, and the two guide rods 353 are respectively located on the left and right sides of the threaded rod 352, and the front and rear sides of the two guide rods 353 are respectively fixedly connected to the inner cavity of the U-shaped support plate 31;

[0041] The working principle of the utility model is as follows: first, through the action of the hydraulic rod 331, the connecting slide plate 332 drives the connecting rod 334 to move upward under the action of the guide slide rod 333, so that the scraper plate 34 below moves upward to the lower surface of the PE film, and then the motor 351 is used to rotate the threaded rod 352. Since the threads of the outer walls of the front and rear parts of the middle part of the threaded rod 352 are opposite, the two slide blocks 354 move toward each other under the action of the guide rod 353 under the action of the threaded rod 352, so that the two scraper blocks 355 move toward each other, and by adjusting the positions of the two scraper blocks 355, the two scraper blocks 355 can be moved toward each other. It is enough to overlap with the front and back sides of the PE film. After adjustment, the guide roller 5 is driven by the motor to rotate, so that the PE film is moved. At this time, under the rotation of the coating roller 4, the glue in the inner cavity of the coating glue groove 21 is evenly applied to the lower surface of the PE film, and the PE film coated with glue moves to the right to the upper surface of the scraper plate 34. At this time, under the action of the scraper plate 34 and the scraper block 355, the excess glue on the lower surface of the PE film is scraped off while the PE film moves, and the scraped excess glue falls downward into the inner cavity of the guide inclined plate 22. Under the action of the guide inclined plate 22, the glue is returned to the inner cavity of the coating glue groove 21 for use.
