[0034] Example: Figure 1-4 As shown, this utility model provides a technical solution: an automatic coating device for coupling agent of composite insulators, including a coating workbench 1, a gantry frame 2 connected to the middle of the top of the coating workbench 1 by a thread, and a moving coating and thickness adjustment mechanism 3 provided at the top of the gantry frame 2.

The other end of the connecting bend 311 is embedded in the top end of the lifting and painting spray pipe 306.

[0039] An insulator lifting and adjustment mechanism 4 is provided at one side of the top of the painting workbench 1. The insulator lifting and adjustment mechanism 4 includes a limiting groove 401, a bidirectional lead screw 402, a limiting slider 403, a support plate 404, an anti-deviation rod 405, an upper pressure plate 406, a shim 407, and a support spring 408.

[0040] A limiting groove 401 is provided at the top of the painting workbench 1, corresponding to one side of the gantry frame 2. A two-way lead screw 402 is rotatably connected inside the limiting groove 401.

[0041] Both ends of the double-acting screw 402 are threadedly connected to limit sliders 403. The top of the limit slider 403 is clamped to a support plate 404. The top of the support plate 404 is symmetrically clamped to an anti-deviation rod 405. An upper pressure plate 406 is movably sleeved on the outside of the anti-deviation rod 405.

[0042] The top of the anti-deviation rod 405 is fitted with a shim 407, and a support spring 408 is fitted between the shim 407 and the upper pressure plate 406 at the corresponding outer position of the anti-deviation rod 405. In order to facilitate the adjustment of the distance between the two support plates 404, a turntable is fitted at both ends of the bidirectional screw 402. The threads at both ends of the bidirectional screw 402 rotate in opposite directions. The outer side of the limiting slider 403 is slidably connected to the inner wall of the limiting groove 401.

[0043] The top of the gantry 2 is symmetrically fitted with positioning protrusions 5. The positioning protrusions 5 are symmetrically rotated and connected with rotating sleeves 6. The rotating sleeves 6 are connected with push rods 7 by threads, and the other end of the push rods 7 is fitted with movable baffles 8. One end of the movable baffles 8 is connected with a touch switch 9 by bolts. In order to facilitate limiting the movement distance of the moving platform 304, the bottom end of the movable baffles 8 is slidably connected to the inner wall of the reciprocating slide 301. The touch switch 9 is powered by an external power supply, and the signal output end of the touch switch 9 is connected to the input end of the drive motor 303 and the conveying pump 310.

[0044] The working principle and usage process of this utility model are as follows: First, rotate the bidirectional lead screw 402 as needed, pushing the two limiting sliders 403 to move the support plate 404 synchronously relative to each other along the limiting groove 401, adjusting the distance between the two support plates 404, forcing the support plate 404 to support composite insulators of different lengths, and then, through the extension and retraction characteristics of the support spring 408, push the upper pressure plate 406 down, and cooperate with the support plate 404 to clamp and fix the composite insulator, ensuring the stability of the composite insulator, thereby reducing shaking during the subsequent coating process;

[0045] Next, rotating the rotating sleeve 6 pushes the top rod 7, the movable baffle 8 and the touch switch 9 to move. According to the coating length of the composite insulator, the distance between the two touch switches 9 is adjusted to facilitate limiting the movement distance of the moving platform 304, improve the adaptability of coating, and can be turned off in time after coating to reduce waste.

[0046] During the coating process, the delivery pump 310 and drive motor 303 are started simultaneously, allowing the coupling agent to enter the lifting coating nozzle 306 through the infusion hose 309 and connecting bend 311. The agent is then sprayed evenly to coat the composite insulator. At the same time, the drive motor 303 pushes the moving platform 304, the adjusting drum 305, and the lifting coating nozzle 306 to move at a constant speed inside the reciprocating slide 301. The composite insulator is then automatically coated according to the set distance, which improves convenience. Furthermore, when the moving platform 304 is disconnected from the touch switch 9 at one end, the delivery pump 310 and drive motor 303 are shut off in time to reduce waste.

[0047] Finally, the adjusting drum 305 is rotated, and the lifting coating nozzle 306 is raised by the limiting telescopic sleeve 307. The distance between the lifting coating nozzle 306 and the composite insulator is adjusted as needed, thereby adjusting the coating height. Since the higher the coating height, the thinner the coating thickness, the coating thickness can be freely adjusted.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
