[0022] Beneficial effects of the present invention:

[0024] Through the coordinated arrangement of the first gear disc, the slide groove, the first slider, the heating lamp tube, the adjustment unit, and the driving unit, the spraying assembly rotates to evenly spray the outer wall of the generator housing, and at the same time, the distance between the spraying assembly or the heating lamp tube and the outer wall of the generator housing can be adjusted, so as to facilitate the spraying of generator housings of various diameters;

[0025] Preheating and baking the generator housing side wall between the two spray paint components by two heating lamps can effectively remove moisture from the generator housing surface, promote paint drying and adhesion, and improve the quality and durability of the coating;

[0026] At the same time, along the rotation direction of the first gear disc, any heating lamp can bake the paint layer sprayed on the generator housing by the previous spray paint assembly to accelerate its drying, thereby speeding up the efficiency of the entire painting process, improving work efficiency and reducing labor intensity;

[0027] In the multi-layer painting process, the heating lamp tube allows each layer of paint to be fully dried, forming a more solid and continuous coating structure, improving the adhesion and wear resistance of the coating, and extending the service life of the coating;

[0028] The present invention facilitates automatic adjustment of the distance between each first sliding block and the central axis of the placement plate by coordinating the second toothed disk, the arc groove, the pin shaft, the first gear, and the first rotating motor.

[0029] The present invention facilitates the real-time replenishment of the paint in the paint tube by means of the coordinated arrangement of the paint tube, the nozzle unit, the paint box and the paint pump, so as to keep the paint in the paint tube always filled with paint.

[0030] At the same time, the first toothed disc rotates in conjunction with the painting process, so that the stirring member rotates around the central axis of the first toothed disc in the paint box and stirs the paint in the paint box to prevent the paint in the paint box from solidifying;

[0031] The paint pump is arranged on any stirring member, so as to avoid the paint tube from getting entangled in the first gear disc or the paint box during the painting process;

[0032] The present invention facilitates automatic adjustment of the length of the paint tube above the upper end surface of the first slide block through the coordinated arrangement of the ear plate, the first telescopic cylinder, the second slide block, and the first spring, and can keep the paint tube above the upper end surface of the first slide block in a vertically placed state at all times, so as to be applicable to the spraying processing of generator housings of various height specifications;

[0033] The present invention cooperates with the conduit, the atomizing nozzle, the second spring and the sealing ball. When the nozzle units are placed tilted downward or vertically downward, the sealing ball squeezes and compresses the second spring under the action of gravity, and the sealing ball retracts into the conduit to seal it, so that the nozzle unit below the upper end surface of the first slider stops working, thereby reducing the waste of paint.

[0061] The paint spraying components all include a paint tube 541 arranged on the corresponding first slider 53. The paint tube 541 is located on the upper end surface of the first slider 53 and is placed vertically upward. The paint tube 541 is in the shape of a sealed shell tube with a hollow interior. A plurality of nozzle units are arranged on the peripheral wall of the paint tube 541 close to the central axis of the support shaft 2. The plurality of nozzle units are evenly distributed along the axial direction of the paint tube 541. The paint tube 541 is filled with paint. The paint in the paint tube 541 enters the nozzle unit and is sprayed onto the peripheral wall of the generator housing through the nozzle unit.

[0062] In order to facilitate the real-time replenishment of the paint in the paint tube 541 and keep the paint in the paint tube 541 always full, a circular paint box 7 is provided directly below the first toothed disc 51, and the paint box 7 is placed coaxially with the first toothed disc 51.

[0064] At the same time, the paint pump 8 is fixed on the stirring member 9, so that the paint pump 8 and the paint tube 541 rotate synchronously with the first toothed disc 51, which can prevent the paint tube 541 from being entangled in the first toothed disc 51 or the paint box 7 during the painting process.
