The partition 12 divides the space inside the spraying box 1 into a spraying area 121 and a baking area 122. A spraying gun 111 is installed on the inner wall of the box cover 11 corresponding to the spraying area 121, and a baking component is installed on the inner wall of the box cover 11 corresponding to the baking area 122. A rotating seat 13 is rotatably installed in the middle of the spraying box 1. A plurality of support rods 14 extend out of the rotating seat 13. A fixture 141 for clamping the metal parts is installed at the end of the support rod 14. A stepping motor 131 for driving the rotation of the rotating seat 13 is installed at the lower end of the spraying box 1. The metal parts in the spraying area 121 are sprayed by the spraying gun 111, and then the stepping motor 131 drives the rotation of the rotating seat 13, so that the sprayed metal parts are sent into the baking area 122 for drying. At the same time, the remaining metal parts to be sprayed are successively sent into the spraying area 121 for spraying. The circulating rotation of the rotating seat 13 realizes the flow production operation, improving the processing efficiency.

[0025] Please refer to Figure 3 , the support rod 14 is rotatably installed on the rotating seat 13. A first bevel gear 142 is fixedly installed at one end of the support rod 14 close to the rotating seat 13. An installation seat 15 is arranged at the upper end of the rotating seat 13. A second bevel gear 152 is movably installed on the installation seat 15. The second bevel gear 152 meshes with a plurality of the first bevel gears 142. A driving motor 151 is fixed on the box cover 11. The output shaft of the driving motor 151 is fixedly connected with the second bevel gear 152. By driving the second bevel gear 152 and the first bevel gear 142 to rotate by the driving motor 151, the support rod 14 rotates around its own axis, thereby driving the fixture 141 and the metal parts to rotate. In the spraying area 121, the spraying operation can be carried out evenly and comprehensively, and in the baking area 122, the drying operation can be carried out evenly, with good practicability.

[0026] Please refer to Figures 1 - 4, a sealing plate 123 is movably installed at the lower end of the partition plate 12 through a hinge. The sealing plate 123 is arranged along the length direction of the partition plate 12. The spraying area 121 is sealed by the sealing plate 123 to prevent the sprayed paint from entering the baking area 122 and affecting the drying process of the metal parts. A plurality of pushing blocks 132 are fixedly installed on the outer wall of the rotating seat 13. The pushing blocks 132 are located above the support rods 14. The pushing blocks 132 are movably connected to the sealing plate 123. The length of the pushing blocks 132 is not less than the width of the metal parts. It is convenient to push the sealing plate 123 to rotate and open through the pushing blocks 132, so as to make space for the metal parts to move out or into the spraying area 121, avoiding the contact between the sealing plate 123 and the metal parts sprayed with paint and affecting the adsorption of the paint. And when the rotating seat 13 rotates, the pushing blocks 132 automatically push the sealing plate 123 to open. When the sealing plate 123 is staggered with the pushing blocks 132, the sealing plate 123 automatically resets to ensure the sealing effect of the spraying area 121. Arc surfaces are provided at both ends of the pushing blocks 132 to reduce the scraping contact between the pushing blocks 132 and the sealing plate 123, playing a role in protecting the sealing plate 123 and extending the service life of the sealing plate 123.

[0027] Please refer to Figure 1 , Figure 4 , a limiting block 16 is also fixedly installed on the bottom wall of the spraying box 1. The limiting block 16 is movably connected to the sealing plate 123. The limiting block 16 plays a role in limiting the sealing plate 123, avoiding the shaking of the sealing plate 123 during reset when losing the support of the pushing blocks 132 and affecting the processing of the metal parts.

[0028] Please refer to Figure 1 , the baking assembly includes a plurality of electric heating tubes 112. A plurality of circles of the electric heating tubes 112 are arranged around the central outer edge of the box cover 11. The electric heating tubes 112 are fixedly installed on the inner wall of the box cover 11 in an arc shape. The baking area 122 is fully covered by the electric heating tubes 112, so as to improve the drying effect of the paint on the metal parts.

[0029] Please refer to Figure 1 , an opening 17 is provided on one side of the spraying box 1. It is convenient to take and place the metal parts through the opening 17.

[0030] The working principle of the first embodiment of the present invention is as follows:

[0031] When in use, the metal piece to be sprayed is placed into the spray box 1 through the opening 17, and the metal piece is fixed by the clamp 141. The stepper motor 131 is started, and the stepper motor 131 drives the rotating seat 13 to rotate clockwise. The push block 132 on the rotating seat 13 pushes the sealing plate 123 to open, and the metal piece is sent into the spray area 121 at the same time. When the push block 132 and the sealing plate 123 are staggered, the sealing plate 123 automatically resets and closes under the action of gravity to ensure the sealing of the spray area 121. The drive motor 151 is started, and the output shaft of the drive motor 151 rotates to drive the second bevel gear 152 to rotate. The second bevel gear 152 drives the first bevel gear 142 to rotate, thereby driving the support rod 14 and the clamp 141 to rotate, so that the metal piece rotates around the axis of the support rod 14, and the spray gun 111 is started to spray paint on the metal piece. The rotation of the metal part itself ensures uniform spraying of the paint. After the paint is sprayed, the stepper motor 131 drives the rotating seat 13 to rotate clockwise, and the push block 132 on the rotating seat 13 pushes the sealing plate 123 to open, and the metal part is sent from the spraying area 121 to the drying area. When the push block 132 and the sealing plate 123 are staggered, the sealing plate 123 automatically resets and closes under the action of gravity, and the metal part is dried by the heat of the electric heating tube 112. The metal part in the drying operation continues to rotate under the drive of the driving motor 151, ensuring that the metal part is fully and evenly dried, and the drying effect is good; when the metal part that has been sprayed enters the drying area from the spraying area 121, the next metal part to be sprayed enters the spraying area 121, so as to continue the spraying operation, realize the flow operation of spraying and drying, and have high processing efficiency.
