[0046] The spraying equipment in S4 includes a processing box 100 , a conveyor belt 200 and a plurality of fixed structures 300 .

[0047] The fixed structure 300 includes a mounting plate 301, two support plates 302 and a fixing rod 304. The mounting plate 301 is fixedly arranged on the conveyor belt 200. The two support plates 302 are symmetrically fixedly arranged on the top of the mounting plate 301. Support rods 303 are movably arranged on the two support plates 302. The ends of the support rods 303 that are away from each other are provided with flipping assemblies. The fixing rod 304 is movably arranged on the opposite end faces of the support rods 303. The fixing rod 304 is used to limit the position of the plug board. The flipping assembly includes a gear 306 and a tooth plate 307. The gear 306 is fixedly arranged at one end of the support rod 303. The tooth plate 307 is fixedly arranged on the inner wall of the processing box 100. The gear 306 meshes with the tooth plate 307 as the conveyor belt 200 moves. The support rod 303 is cross-shaped, and the end face of the other end of the support rod 303 is concave. A first spring 305 is fixedly arranged between the support rod 303 and the fixing rod 304.

[0048] Specific reference Figure 1 , Figure 2 and Figure 5 The conveyor belt 200 is movably arranged in the processing box 100, and the two opposite ends of the processing box 100 are connected. The conveyor belt 200 passes through the processing box 100, which is convenient for loading and unloading the plug board spraying process. The mounting plate 301 is made of elastic material, such as elastic plastic, which is convenient for changing its shape with the transmission of the conveyor belt 200, thereby ensuring the effectiveness of installation on the conveyor belt 200. The support plate 302 provides effective support for the installation of the support rod 303. The other end of the support rod 303 is connected to the fixing rod 304 through the first spring 305. The end of the fixing rod 304 away from the support rod 303 The part can squeeze the side of the power strip so that the power strip can maintain a stable position during the movement. When it moves to a certain position for spraying, the gear 306 and the tooth plate 307 move and engage, causing the gear 306 to drive the support rod 303 to rotate, thereby synchronously driving the fixed rod 304 to rotate, so that the fixed rod 304 can drive the power strip to rotate and spray, reducing the tediousness of manual turning over of the power strip for spraying, effectively improving the flexibility of the power strip spraying process, and the above can simultaneously spray multiple power strips, thereby enhancing the overall efficiency of power strip preparation.

[0049] A positioning structure 400 for limiting the position of the fixed rod 304 is arranged above the scraper 502. The positioning structure 400 includes a positioning rod 401, a positioning groove 402, and a fixing plate 403. The positioning rod 401 is movably arranged above the scraper 502. The positioning groove 402 is opened on the outer wall of the fixing rod 304. The positioning groove 402 is annular. The fixing plate 403 is sleeved on the outside of the positioning rod 401. One side of the fixing plate 403 is fixed to the support plate 302. The bottom end of the positioning rod 401 is arc-shaped. A second spring 404 is fixedly arranged between the positioning rod 401 and the fixing plate 403.

[0050] Specific reference Figure 3 The positioning rod 401 is supported by the fixing plate 403 and the second spring 404. The positioning groove 402 is arranged in a ring shape, so that the positioning rod 401 and the positioning groove 402 can be flexibly interlaced without affecting the rotation of the fixing rod 304. Therefore, after the positioning rod 401 and the positioning groove 402 are connected, the fixing rod 304 can be strengthened to firmly clamp the plug board and facilitate the stability of the subsequent plug board flipping. The second spring 404 is fixedly sleeved on the outer wall of the positioning rod 401, and the second spring 404 is fixedly arranged inside the fixing plate 403, which plays a reset support role for the positioning rod 401.

[0051] A collecting structure 500 is movably provided at the top of the mounting plate 301, and the collecting structure 500 includes a collecting trough 501, two scrapers 502 and a driving assembly.

[0052] Specific reference Figure 4, the collecting tank 501 is located below the power strip, and when the power strip is being sprayed, the excess paint can fall into the collecting tank 501 for collection, which can avoid waste and pollution of the paint and effectively improve the environmental friendliness of the power strip spraying process. The scraper 502 is symmetrically located in the inner cavity of the collecting tank 501, and can gather the paint in the collecting tank 501 by moving after collection, so that the paint can be better taken out and reused. At the same time, the scraper 502 can scrape the inner wall of the collecting tank 501, which can reduce the probability of the paint adhering to the collecting tank 501, enhance the cleanliness of the use of the collecting tank 501, and further enhance the integrity of the paint collection. The movable plate 503 is fixedly arranged on the side of the scraper plate 502, and the movable plate 503 is in an inverted L-shape, which is convenient for fixing with the scraper plate 502 and can be connected with the movable rod 504 at the same time. The movable rod 504 is a bidirectional screw, and the movable rod 504 is threadedly connected to the movable plate 503. One end of 504 passes through the outer wall of one of the limit plates 505 and extends to the outside.

When the scraper 502 moves to the top of the positioning rod 401, it will squeeze the positioning rod 401. Under the arc-shaped setting at the bottom end of the positioning rod 401, the positioning rod 401 is prompted to generate an upward moving force, so that the positioning rod 401 and the positioning groove 402 can be movably interlaced, and then the position of the fixed rod 304 can be reinforced to ensure the stability of the fixed rod 304 clamping the power strip, and the collection groove 501 and the mounting plate 301 are installed and limited by a straight up and down embedding method, so that the collection groove 501 can be flexibly disassembled and assembled on the mounting plate 301, which is convenient for the removal and reuse of the paint body in the collection groove 501.

[0053] A plurality of protective plates 600 are fixedly arranged on the inner wall of the processing box 100, and the plurality of protective plates 600 are all used to limit the spraying range of the power strip. The processing box 100 includes a box body 101, a plurality of spray guns 102, two spray pipes 103, a delivery pipe 104 and a paint tank 105.
