[0036] Working steps

[0037] First, the motor 3 is started, and the threaded rod 4 is driven to move by the motor 3, and then the moving block 6 is driven to move inside the accommodating hole 5 under the movement of the threaded rod 4. The purpose is to convert the rotation of the motor 3 into a linear force so that the moving block 6 can move up and down, and then the movement of the moving block 6 will drive the connecting block 7 to move, and then the supporting block 8 will also move, and then the adjusting roller 9 is driven to move up and down under the movement of the supporting block 8, and with the assistance of the fixed column 10, the stability of the movement is ensured, which can adjust the tension of the substrate to ensure that the substrate has good tension during coating and reduce the possibility of wrinkles, and then under the elastic force of the strong spring 13, substrates of different thicknesses can be achieved. When facing a thicker substrate, the coating roller 15 will drive the movable block 14 to slide upward on the outside of the fixed rod 12, and then when facing a thinner substrate, it will move downward due to the elastic force of the strong spring 13, and the coating roller 15 and the coating roller 15 can be automatically adjusted according to substrates of different thicknesses. The spacing between the coating rollers 16 can be such that a pattern to be coated can be provided on the coating rollers 16, and a driving end can be connected to one end of the coating rollers 16, which can drive the coating rollers 15 and the feeding rollers 19 to rotate. Because the spacing between the coating rollers 16 and the coating rollers 15 and the feeding rollers 19 allows them to drive each other, they can act as a driving source in the mid-coating process. Then, under the rotation of the feeding rollers 19, the liquid to be coated in the storage box 17 can be driven to the coating rollers 16 by the rotation, and then the substrate can be coated. The material is coated. When the feeding roller 19 needs to be replaced, it is only necessary to pull the pull plate 24. The pull of the pull plate 24 drives the pull rod 20 to move, and then drives the limit plate 22 to make the chamber 21 subject to force. In this process, the outside of one side of the pull rod 20 will be separated from the inside of the connecting plate 18. At this time, the connecting plate 18 can drive the feeding roller 19 to be pulled out for cleaning. When installation is required, the force applied to the chamber 21 will generate a rebound force to provide the force for the connecting plate 18 and the feeding roller 19 to be engaged.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
