The two screw rods 1 are respectively connected to both ends of the rotating shaft of the roller coating wheel 13, so as to realize the height adjustment of the roller coating wheel 13; the adjusting mechanism 2 includes a servo motor 2, a worm and worm gear 2 driven by the servo motor 2, and two screw rods 2 driven by the worm and worm gear 2 and synchronously lifted and lowered. The two screw rods 2 are respectively connected to both ends of the rotating shaft of the metering wheel 14, so as to realize the distance adjustment from the roller coating wheel 13.

[0025] In this Embodiment 1, by providing the adjusting mechanism 2 corresponding to the metering wheel 14, the position of the metering wheel 14 can be flexibly adjusted to adjust the distance between the metering wheel 14 and the roller coating wheel 13, so that the working parameters can be customized according to the thickness of different products, increasing the diversity of the thickness of the roller-coated products; by providing the adjusting mechanism 1 corresponding to the roller coating wheel 13, the height of the roller coating wheel 13 can be adjusted according to the wear degree of the roller coating wheel 13 to compensate for the wear value of the roller coating wheel 13, and the roller coating wheel 13 can be made to leave the working position during the non-working period of the equipment, ensuring that the roller coating wheel 13 will not be single-point pressed during the non-working period to improve the service life of the roller coating wheel 13.

[0026] Embodiment 2:

[0027] Based on Embodiment 1, Embodiment 2 further includes a pressing wheel 11 arranged in parallel with the supporting wheel 12. The pressing wheel 11 is located directly below the supporting wheel 12 and is in line contact with the supporting wheel 12 to take away the liquid on the surface of the supporting wheel 12. A third adjusting mechanism is provided corresponding to the pressing wheel 11 to adjust the pressing degree between the pressing wheel 11 and the supporting wheel 12.

At this time, the coating on the roller coating wheel 13 will adhere to the surface of the supporting wheel 12. To cope with this situation, the design of adding the pressing wheel 11 below the supporting wheel 12 is adopted. The pressing wheel 11 is adjusted to press the supporting wheel through the third adjusting mechanism. By controlling the position and pressing degree of the pressing wheel 11, the liquid on the surface of the supporting wheel 12 is squeezed out. After the liquid is collected, it flows into the lower tray 15 for recycling, which can effectively reduce the dry solidification phenomenon of the roller coating liquid on the surface of the supporting wheel 12 and reduce the problem of the lower surface of the product being contaminated with the coating, thereby solving the product quality problem caused by the liquid on the supporting wheel 12; and the pressing wheel 11 can be separated from the supporting wheel 12 during the non-working period of the equipment to ensure that the supporting wheel 12 will not be singly stressed during the non-working period to improve the service life of the supporting wheel 12.

[0032] In Embodiment 3, after the roller coating work is completed, the cleaning liquid is automatically pumped out from the external cleaning liquid bucket by an external pump through a pneumatic pump and supplied to the spray nozzle 21 through the liquid supply pipe 20. The cleaning liquid is used to clean the coating nozzle and the roller coating wheel 13 fully automatically, so as to replace manual cleaning and prevent the roller coating liquid from drying and solidifying inside the coating nozzle and on the surface of the roller coating wheel 13.
