The power mechanism 2 is a reducer, and in this embodiment, the reducer is a high-precision reducer, which can avoid the generation of horizontal lines caused by the accuracy of the reducer itself.
[0025] In this embodiment, the partition wall is detachably connected to the base 1 through a first connecting member. The partition 3 is arranged vertically; the first connecting member includes a first plate body 41 and a second plate body 42 connected to each other, and the connection method of the first plate body 41 and the second plate body 42 can be welding; the first plate body 41 and the second plate body 42 are perpendicular to each other; the first plate body 41 is provided with a first through hole, and the second plate body 42 is provided with a second through hole. The second plate body 42 is threadedly connected to the base 1 through a first bolt, and the first bolt passes through the second through hole and is threadedly connected to the base 1. The partition 3 is welded to the first plate body 41, and the partition 3 is provided with a third through hole. The third through hole is provided with a rotating bearing 7, and the outer wall of the rotating bearing 7 is connected to the partition 3; the third through hole is coaxially arranged with the first through hole.
[0026] The transmission rod 8 passes through the rotating bearing 7 and is connected to the inner wall of the rotating bearing 7. The first end of the transmission rod 8 is connected to the power mechanism 2, and the second end of the transmission rod 8 is connected to the coating roller 6, that is, the power mechanism 2 and the coating roller 6 are respectively located on both sides of the partition 3, and the power mechanism 2 and the coating roller 6 are separated by the partition 3 and the transmission rod 8 to buffer the vibration transmitted from the power mechanism 2 to the coating roller 6.
[0027] The second end of the transmission rod 8 is connected to one end of the coating roller 6 through the first coupling 5. The first coupling 5 is an elastic coupling. The elastic coupling has buffering and vibration reduction properties, further ensuring the smooth operation of the coating roller 6.
[0028] In this embodiment, the other end of the coating roller 6 can also be provided with a power mechanism 2, and shock absorption and buffering are performed through the first coupling 5, the transmission rod 8, and the partition 3. The other end of the coating roller 6 can also be directly connected to the support structure through the first coupling 5 and the transmission rod 8 without a power mechanism, which is not limited in this embodiment.
[0029] As a further improvement of this embodiment, the coating device is further provided with a protective cover 9, which is a semi-enclosed structure with an opening at the bottom, and is used to shield and protect the coating area. The coating roller 6 and the first coupling 5 are located in the protective cover 9; the first connecting member is also provided with a limit plate 43, which extends in the direction of the coating roller 6.

The power mechanism 2 and the coating roller 6 are connected by a transmission rod 8, and the transmission rod 8 is supported and fixed by the partition 3, thereby reducing the vibration transmitted from the power mechanism to the coating roller 6. Furthermore, a first coupling 5 is provided, and the first coupling 5 is an elastic coupling, which can further cushion the vibration of the power mechanism 2. Since the vibration transmitted to the coating roller 6 is greatly reduced, the coating roller 6 can rotate smoothly, thereby avoiding the generation of horizontal coating streaks.
