With continued reference to fig. 1 and 2, that is, in the preferred embodiment, two coating actuators 20 are provided and are spaced apart in a horizontal direction. The first auxiliary coating mechanisms 30 are provided in two and arranged side by side at an interval in the horizontal direction. The second auxiliary coating mechanisms 40 are also provided in two and arranged side by side at intervals in the horizontal direction. Each of the first auxiliary coating mechanism 30, the coating actuator 20, and the second auxiliary coating mechanism 40 is disposed at a vertical interval and side by side.
Of course, the number of the coating actuators 20, the first auxiliary coating mechanisms 30, and the second auxiliary coating mechanisms 40 in other embodiments and arrangements may be varied as long as the requirements for efficient and high quality coating operations are met.
With continued reference to fig. 7-10, in some embodiments, the first auxiliary coating mechanism 30 and the second auxiliary coating mechanism 40 each include an auxiliary coating roller 50.

The float assembly 80 provides the primary and secondary applicator cylinders 22, 50 with the ability to float telescopically so that both can be well adapted to uneven, inclined or angled wall surfaces.
With reference to fig. 4 and fig. 8 to fig. 10, specifically, the floating assembly 80 includes a floating sliding sleeve 81, a floating sliding shaft 82, an elastic expansion piece 83 and an anti-falling baffle 84, the floating sliding sleeve 81 is disposed on the roller fixing base 70, the floating sliding shaft 82 is slidably disposed in the floating sliding sleeve 81, two ends of the floating sliding shaft 82 are respectively connected to the anti-falling baffle 84 and the roller bracket 60, the elastic expansion piece 83 is sleeved outside the floating sliding shaft 82, and two ends of the elastic expansion piece 83 respectively abut against the roller fixing base 70 and the roller bracket 60.
When the main coating roller 22 or the auxiliary coating roller 50 contacts uneven or inclined wall surfaces, the roller bracket 60 is forced to carry the main coating roller 22 and the auxiliary coating roller 50 away from or close to the wall surfaces due to the acting force of the wall surfaces, the floating sliding shaft 82 slides back and forth relative to the floating sliding sleeve 81 in the process, the elastic expansion piece 83 correspondingly expands and deforms to provide rebound pressing force, so that the main coating roller 22 and the auxiliary coating roller 50 can adapt to the shape of the wall surfaces to expand and float and are always attached to the wall surfaces, and the coating efficiency and the coating quality are ensured. The anti-falling baffle 84 is used for preventing the floating sliding shaft 82 from falling off from the floating sliding sleeve 81, and improving the connection and sliding reliability of the floating sliding shaft and the floating sliding sleeve.
Further, the diameter of the floating sliding shaft 82 is smaller than the inner diameter of the floating sliding sleeve 81. The floating sliding sleeve 81 provides a swinging space for the floating sliding shaft 82, so that the floating sliding shaft 82 can swing left and right relative to the floating sliding sleeve 81, even if the main coating roller 22 and the auxiliary coating roller 50 have horizontal swinging capacity, thereby better adapting corners, corners and uneven wall surfaces, and ensuring the coating quality and efficiency.

When the worn or damaged main coating roller 22 and auxiliary coating roller 50 need to be replaced, the card 90a is rotated upwards, and the roller 100 is disengaged from the engagement of the engaging groove 901a, so that the main coating roller 22 and the auxiliary coating roller 50 can be quickly removed. The assembly and disassembly operation is convenient and labor-saving.
The roller bracket 60 is also provided with a bayonet, and the rollers 100 of the main coating roller 22 and the auxiliary coating roller 50 are inserted into the bayonet, so that the installation is stable and the rollers are not easy to fall off.
With reference to fig. 7 and 8, in addition, the first auxiliary coating mechanism 30 further includes a bump switch 31 and a fixing bracket 32, and the bump switch 31 is disposed on the roller fixing base 70 through the fixing bracket 32. The anti-collision switch 31 plays a role in protection. That is, the anti-collision switch 31 protrudes from the outer contour of the liquid coating execution terminal, and when the whole liquid coating execution terminal approaches too close to the wall surface, the anti-collision switch 31 firstly touches the wall surface to generate a trigger signal, so that the liquid coating execution terminal stops moving continuously, and the problem of collision damage is prevented.
