They utilize a specialized multifunctional coating head capable of producing a variety of surface coatings. To enhance the sun protection properties of protective films, sunscreen paint is often applied to one or both sides of the existing film.

[0003] Publication No. CN212216069U discloses a precision sunscreen coating machine specifically for manufacturing protective films. A rotating drum drives a scraper to contact the discharge port and the sunscreen paint on the discharge port, quickly and evenly spreading the sunscreen paint on the discharge port to ensure uniform coating. Furthermore, the height of the telescopic rod can be adjusted to adjust the coating thickness according to different sunscreen requirements and paint properties. This allows for convenient control of sunscreen coating during production and processing, helping to save production costs and improve production quality. However, this patent still presents the following problems in actual use:

The surface of the water inlet pipe 9 away from the water pump 8 is connected to the mixing box 4, and the other side of the water pump 8 is fixedly connected to the water outlet pipe 10. The water outlet pipe 10 is connected to the box body 3. One side of the surface of the water outlet pipe 10 is connected to the limiting sleeve 11, and the top surface of the limiting sleeve 11 is fixedly connected to the box body 3. The bottom surface of the water outlet pipe 10 is connected to the spraying device 12. Inlet and outlet 13 are symmetrically provided on both sides of the box body 3. Several supporting rollers 14 are fixedly installed inside the box body 3. A drying device 18 is fixedly installed on one side of the top surface of the box body 3. Figure 2 As shown, the water pump 8 can be used to transport the paint inside the mixing box 4 to the inside of the spraying device 12, so that the paint protection film can be sprayed by the spraying device 12. At the same time, the drying device 18 can be used to quickly dry the paint on the paint protection film. The support roller 14 can support the paint protection film. The entrance and exit 13 is convenient for the paint protection film to enter and exit. At the same time, winding rollers and output rollers are provided on both sides of the paint protection film. Through the cooperation of the winding rollers and the output rollers, the tension of the paint protection film is maximized, which facilitates the spraying of the spraying device 12, and the scraper 17 can scrape the paint on the paint protection film evenly, and also prevent the paint protection film from being deformed when the scraper 17 is scraping the paint protection film evenly.

[0032] The output end of the driving motor 7 passes through one side surface of the mixing box 4 and is fixedly connected to a rotating rod 19. A plurality of stirring blades 20 are symmetrically installed on both sides of the rotating rod 19. The side surface of the rotating rod 19 away from the driving motor 7 is rotatably connected to the mixing box 4. Figure 3 As shown, after the paint is poured into the interior of the mixing box 4 through the feed port 5, the drive motor 7 is started so that the drive motor 7 can drive the rotation of the rotating rod 19.

Figure 4 As shown, the engagement of the card slot 23 with the card rod 2204 allows the scraper 17 to be quickly installed and disassembled.

[0034] Working principle: Before using this kind of car paint protection film coating machine, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, first, when the scraper 17 needs to be disassembled and cleaned from time to time, the door of the box body 3 is opened and the pressure rod 2202 is rotated so that the rotation of the pressure rod 2202 can drive the rotation of the limit block 2208, so that the limit block 2208 is rotated to the leftmost side of the L-shaped limit groove 2209, so that the limit block 2208 and the rightmost side of the L-shaped limit groove 2209 are no longer engaged, and then the pressure rod 2202 is loosened so that the spring 2205 can lift the connecting plate 2203. After the connecting plate 2203 is lifted up, the pressure rod 2202 is lifted up. At the same time, when the connecting plate 2203 rises, the card rod 2204 can also be driven to rise, so that the card rod 2204 is separated from the card slot 23, thereby facilitating the removal of the scraper 17. At the same time, when installing the cleaned scraper 17, after the top surface of the scraper 17 is tightly fitted with the bottom surface of the stabilizing plate 16, the pressure rod 2202 is pressed, so that the pressure rod 2202 can drive the connecting plate 2203 to descend, and the connecting plate 2 The descent of 203 can drive the card rod 2204 to descend. At the same time, when the connecting plate 2203 descends, the spring 2205 can be squeezed, so that the spring 2205 is deformed. At the same time, when the card rod 2204 descends and the card rod 2204 is engaged with the card slot 23, the limit block 2208 on the pressure rod 2202 is just moved to the bottom of the L-shaped limit slot 2209. At the same time, by rotating the pressure rod 2202, the pressure rod 2202 can drive the rotating block to move to the bottom of the L-shaped limit slot 2209. The right side moves so that the L-shaped limit groove 2209 will limit the limit block 2208. At the same time, the spring 2205 will lift the connecting plate 2203 and the pressure rod 2202, so that the fit between the limit block 2208 and the limit groove 2209 can be tighter, so that when there is no external interference, the limit block 2208 and the limit groove 2209 will not be separated, thereby improving the rapid disassembly and installation of the scraper 17.

[0035] Secondly, after the paint is poured into the mixing box 4 through the feed port 5, the drive motor 7 is started so that the drive motor 7 can drive the rotation of the rotating rod 19. The rotation of the rotating rod 19 can drive the rotation of the stirring blade 20, so that the paint inside the mixing box 4 can be stirred evenly, making it easier to carry out the subsequent coating operation.
