Description

Technical Field

[0001] The utility model relates to the technical field of car cover film coating, in particular to a coating device for a car cover film with uniform coating liquid and anti-sagging. Background Art

[0002] In the production of car cover films, the accuracy, uniformity and anti-sagging performance of coating technology have become important indicators for measuring coating quality. The anti-sagging ability is directly related to the flatness and aesthetics of the coating, and can effectively prevent the coating from flowing due to gravity during the drying process, thereby ensuring that the car cover film has excellent surface quality and protective performance. Therefore, continuously optimizing coating technology and improving anti-sagging performance are of great significance to improving the overall quality and market competitiveness of car cover films.

[0003] For example, a film coating device and a coating method disclosed in Chinese patent application publication number CN118751474A realize uniform coating of the coating liquid on both sides of the film through a material leveling and anti-sagging component, and preheat the coating liquid by using a preheating roller to promote its solidification inside the material leveling component, thereby ensuring the coating effect and preventing sagging. However, the device faces some challenges in practical application. First, the positions of its scraper and scraper are relatively fixed, which makes it difficult to adapt to car cover films of different sizes, resulting in the problem of effective scraping of the coating liquid. Secondly, the device relies on a spring to make the scraper fit the film. When there are uneven surfaces on the film, the scraper is prone to jumping under the action of the spring force, which may damage the film. In addition, the device is only wound up by a winding roller, and lacks a film guiding design in the feed tray, which makes it difficult for the coating liquid to fully immerse into the film, affecting the coating effect. Therefore, in view of the drawbacks existing in the existing device, we urgently need to improve a coating device for car cover film with material leveling and anti-sagging. Utility Model Content

[0023] Furthermore, the material-averaging anti-sagging component 4 includes a mounting frame 41, which is arranged on the top of the liquid storage frame 21, a transmission roller 42 is arranged inside the mounting frame 41, a first conveyor belt 43 is arranged outside the transmission roller 42, a driving motor 44 is arranged outside the mounting frame 41, a screw 45 is arranged on the output shaft of the driving motor 44, a first movable plate 46 is threadedly connected to the outside of the screw 45, a second conveyor belt 47 is arranged outside the first movable plate 46, a second movable plate 48 is movably arranged inside the mounting frame 41, and a scraper 49 is arranged outside the first conveyor belt 43 and the second conveyor belt 47 to scrape off the redundant coating liquid on the surface of the car cover film 1. It is convenient to scrape off the redundant coating liquid on the outer surface of the car cover film 1 of different sizes.

[0024] Furthermore, a pressing frame 410 is provided inside the first conveyor belt 43 and the second conveyor belt 47 to press the first conveyor belt 43 and the second conveyor belt 47 to ensure the scraping effect. The second conveyor belt 47 is in contact with the second movable plate 48 to prevent the second conveyor belt 47 from rotating with the rotation of the screw 45, thereby ensuring the stable adjustment of the position of the second conveyor belt 47.

[0025] Furthermore, the frame 2 and the liquid storage frame 21 are provided with a winding coating assembly 3 for improving the pre-impregnation effect of the car cover film 1, the winding coating assembly 3 is provided with a reduction motor 31, the reduction motor 31 is provided outside the frame 2, the reduction motor 31 output shaft is provided with a winding roller 32 for winding the car cover film 1, the frame 2 is provided with a guide roller 33 for guiding the car cover film 1, and the liquid storage frame 21 is provided with a pre-impregnation roller 34 for making the car cover film 1 fully contact with the coating liquid.

[0026] Furthermore, at least four groups of pre-impregnation rollers 34 are provided, and the four groups of pre-impregnation rollers 34 are distributed inside the liquid storage frame 21. This facilitates the pre-impregnation of the car cover film 1 and ensures that the coating liquid is evenly impregnated into the car cover film 1.

[0027] Example 2: Please refer to Figure 6 , and combined with the first embodiment, it is further obtained that the frame 2 is also provided with a drying component 5 for drying the car cover film 1 treated by the material balancing and anti-sagging component 4, and the drying component 5 is provided with a connecting frame 51, and the connecting frame 51 is arranged on the top of the mounting frame 41. Two groups of heaters 52 are symmetrically arranged outside the connecting frame 51, and each group of heaters 52 is provided with a heat pipe 53 at the heat transfer end, and a drying plate 54 is arranged on the side of the heat pipe 53 away from the heater 52.

Then the reduction motor 31 is started to drive the winding roller 32, so that the car cover film 1 rises with the liquid level in the liquid storage frame 21. In order to control the amount of coating liquid on the car cover film 1, the distance between the first conveyor belt 43 and the second conveyor belt 47 is adjusted. By starting the drive motor 44 to drive the screw 45 to rotate, under the limiting action of the second movable plate 48, the second conveyor belt 47 moves as a whole until the scraper 49 outside the first conveyor belt 43 and the second conveyor belt 47 sticks to the outside of the car cover film 1 and then the drive motor 44 is turned off. Next, the first conveyor belt 43 and the second conveyor belt 47 are started, and the scrapers 49 on the surfaces thereof, with the assistance of the pressing frame 410, effectively scrape off the excess coating liquid on the surface of the car cover film 1. The treated car cover film 1 enters the connection frame 51, and the heater 52 is operated at this time to send the hot air flow into the drying plate 54 through the heat pipe 53.
