The conversion assembly 45 is configured to be a combination of the conversion rack 451 and the conversion gear 452, so that when the connecting frame 3 moves transversely, the movable block 2 can be driven to move transversely, at this time, the conversion gear 452 can drive the coating roller 122 to rotate due to the action of the conversion rack 451, and a linear velocity V3 can be generated at the contact surface of the coating roller 122 and the plate 6 when the coating roller 122 rotates, so that the linear velocity of the rotation of the coating roller 122 is greater than the linear velocity of the transverse movement of the connecting frame 3, that is, V1< V3.

Here, it is explained why the coating effect is better when the coating roller 122 and the plate 6 have a difference in moving speed during the coating process. The speed of movement of the applicator roll 122 is greater than the speed of movement of the sheet material 6, which results in a relatively high speed shear zone between the applicator roll 122 and the sheet material 6. Such shear zones can create a uniform pressure distribution during the coating process, helping to uniformly distribute the coating liquid over the substrate surface. Since the moving speed of the coating roller 122 is greater than that of the plate material 6, the coating liquid on the surface of the coating roller 122 is forced to flow forward, forming a relatively smooth coating layer. Such surface flow helps to reduce uneven distribution of coating liquid on the surface of the coating roller 122.
