[0035] The defect prevention device 5 comprises a U-shaped scraping box 51, a V-shaped plate 52, a scraper 53, a V-shaped baffle 54 and a collection box 55.

The scraper 53 and the U-shaped scraping box 51 can scrape off the impurities adhered to the surfaces of the supporting roller 26 and the pressure roller 27 respectively, so as to avoid the problem that the surface of the heat transfer film is easily scratched when the heat transfer film is transmitted with impurities adhered to the surfaces of the supporting roller 26 and the pressure roller 27. At the same time, the V-shaped baffle 54 and the V-shaped plate 52 can guide the impurities scraped off by the scraper 53 and the U-shaped scraping box 51 into the collection box 55 for collection.

[0036] The defect prevention device 5 further comprises a convex rod ring 56, a knocking rod 57 and a elastic plate 58.

The convex rod ring 56 is provided with convex rods at the outer wall. The elastic plate 58 is located on the movement track of the convex rods of the convex rod ring 56. When the pressure roller 27 rotates, the convex rod ring 56 rotates, the convex rods of the convex rod ring 56 push the elastic plate 58 to drive the knocking rod 57 to knock the U-shaped scraping box 51, so that the U-shaped scraping box 51 vibrates, thereby improving the efficiency of the impurities scraped off from the U-shaped scraping box 51 into the collection box 55 for collection.

[0037] In use, the heat transfer film is passed over the guide roller 14, and one end of the heat transfer film is adhered to the winding tube 13 by the adhesive tape, while the heat transfer film is passed over the support roller 26. When it is necessary to adjust the winding tension of the heat transfer film, the threaded rod 23 is rotated, the threaded block 24 is moved up and down, the support roller 26 is moved up and down, so that the support roller 26 adjusts the winding tension of the heat transfer film, thereby avoiding the problem that the winding quality of the heat transfer film is poor due to abnormal tension of the heat transfer film. At the same time, under the action of the spring force corresponding to the sliding block 25, the sliding block 25 drives the compression roller 27 to extrude the heat transfer film and tightly adhere to the support roller 26.

At this time, the L-shaped telescopic rod 36 is no longer in contact with the top surface of the heat transfer film, thereby ensuring that the L-shaped telescopic rod 36 can flatten the heat transfer film from the middle to both sides each time.

[0039] At the same time, the rubber surface of the U-shaped telescopic plate 41 rubs against the fur surface of the transmission belt 34, and the fur surface of the transmission belt 34 generates static electricity, thereby causing the static electricity to adsorb dust and impurities on the surface of the heat transfer film, thereby reducing post-production defects of the heat transfer film. At the same time, when the rotating roller 32 rotates, the circular block 44 rotates, the circular block 44 pushes the telescopic end of the U-shaped telescopic plate 41 to move upwards, the telescopic end of the U-shaped telescopic plate 41 drives the U-shaped carriage 42 to move upwards, and the U-shaped carriage 42 drives the scraper 43 to approach the bottom surface of the transmission belt 34. The scraper 43 scrapes the dust and impurities adsorbed on the outer wall of the transmission belt 34, thereby enabling the transmission belt 34 to continuously adsorb dust and impurities. At the same time, the U-shaped carriage 42 drives the L-shaped touch rod 46 to move upwards, the L-shaped touch rod 46 contacts the grounding rod 45, the grounding rod 45 drives the scraper 43 to guide the static electricity on the surface of the transmission belt 34 through the L-shaped touch rod 46, thereby causing the surface of the transmission belt 34 to lose static electricity, so that the dust and impurities scraped by the scraper 43 are not attached to the surface of the transmission belt 34 again by static electricity.

[0040] Meanwhile, the scraper 53 and the U-shaped scraper box 51 can scrape off the impurities adhered to the surfaces of the supporting roller 26 and the pressing roller 27 respectively when the supporting roller 26 and the pressing roller 27 rotate, so that the problem that the surface of the heat transfer printing film is prone to scratches when the heat transfer printing film is transmitted with the impurities adhered to the surfaces of the supporting roller 26 and the pressing roller 27 is avoided, meanwhile, the V-shaped baffle 54 and the V-shaped plate 52 can guide the impurities scraped off by the scraper 53 and the U-shaped scraper box 51 to the collecting box 55 for collection; meanwhile, the pressing roller 27 rotates to drive the convex rod ring 56 to rotate, the convex rod of the convex rod ring 56 pushes the elastic plate 58 to swing downward, the elastic plate 58 drives the knocking rod 57 to move away from the U-shaped scraper box 51, when the convex rod of the convex rod ring 56 passes the elastic plate 58, the elastic plate 58 is reset under the action of the corresponding spring elastic force, the elastic plate 58 drives the knocking rod 57 to knock the U-shaped scraper box 51, the U-shaped scraper box 51 vibrates, so that the efficiency of the impurities scraped off from the U-shaped scraper box 51 into the collecting box 55 for collection is improved.
