[0029] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] like Figures 1-5 As shown, a chain surface spraying device includes: a spraying housing 1, a hanging mechanism 2 for hanging the chain to be sprayed is installed on the spraying housing 1, a spraying mechanism 3 for spraying the chain is provided on the side of the spraying housing 1, a shielding mechanism 4 is installed at the bottom of the spraying housing 1, and a drying fan 5 is installed on the side of the spraying housing 1.

[0032] The hanging mechanism 2 includes a drive motor 201 fixedly connected to the spraying housing 1. A drive shaft 202 is fixedly connected to the output shaft of the drive motor 201. A fixed hanging plate 203 is fixedly connected to the bottom of the drive shaft 202. An adjustable hanging plate 204 is provided at the bottom of the fixed hanging plate 203. Hooks 205 for hanging chains are provided at the edges of both the fixed hanging plate 203 and the adjustable hanging plate 204. By providing the adjustable hanging plate 204, the distance between the adjustable hanging plate 204 and the fixed hanging plate 203 can be adjusted, thus facilitating the hanging of chains of different sizes. An adjusting bolt 2041 is rotatably mounted at the center of the bottom of the fixed hanging plate 203 via a bearing. A threaded sleeve 2042 matching the adjusting bolt 2041 is provided on the adjustable hanging plate 204. Rotating the adjusting bolt 2041, and under the action of the threaded sleeve 2042, the adjusting plate 204 can be adjusted. Limiting telescopic rods 2043 are fixedly connected to both sides of the top of the adjusting plate 204, and the other end of the limiting telescopic rods 2043 is fixedly connected to the bottom of the fixed plate 203. The limiting telescopic rods 2043 limit the adjustment of the plate 204, thereby increasing the stability of the adjustment. A limiting bearing sleeve 2021 is rotatably installed on the drive shaft 202. Both sides of the limiting bearing sleeve 2021 are fixedly installed on the spraying housing 1 via L-shaped connecting rods. The limiting bearing sleeve 2021 limits the drive shaft 202, thereby increasing the stability of the drive shaft 202 driving the fixed plate 203 to rotate.

[0033] The spraying mechanism 3 includes a storage tank 301 located on the top of the spraying housing 1. The spraying mechanism 3 also includes a delivery pump 302 installed on the side of the spraying housing 1. The delivery pump 302 is connected to the storage tank 301 through a connecting pipe 303. A nozzle 304 is installed on the side of the delivery pump 302. The delivery pump 302 delivers the paint to the nozzle 304, thereby enabling the spraying of the chain.

[0034] The shielding mechanism 4 includes a servo motor 401 fixedly connected to the bottom of the spraying housing 1. An L-shaped baffle 402 is fixedly connected to the output shaft of the servo motor 401. The servo motor 401 drives the L-shaped baffle 402 to rotate, which can block the right side of the hanging mechanism 2 during spraying to prevent the paint from affecting the drying fan 5, and block the left side of the hanging mechanism 2 during drying to prevent the drying from affecting the nozzle 304. A limiting roller 4021 is installed on one side of the bottom of the L-shaped baffle 402, and the bottom of the L-shaped baffle 402 is rolledly connected to the bottom of the inner wall of the spraying housing 1 through the limiting roller 4021. The setting of the limiting roller 4021 increases the stability of the rotation adjustment of the L-shaped baffle 402.

[0035] The working principle of this utility model is as follows: First, the two ends of the chain to be sprayed are respectively hung on the hooks 205 on the side of the fixed hanging plate 203 and the adjusting hanging plate 204. Then, by rotating the adjusting bolt 2041, and under the action of the threaded sleeve 2042, the adjusting hanging plate 204 can be adjusted. This not only tightens the chain but also adjusts the distance between the adjusting hanging plate 204 and the fixed hanging plate 203, thus facilitating the hanging of chains of different sizes. Then, the feed material is conveyed to the spray head 304 through the connecting pipe 303. At the same time, the drive motor 201 is turned on, which drives the hung chain to rotate circumferentially. Then, the chain can be sprayed from all directions through the spray head 304, thereby improving the practicality of this utility model.

[0036] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
