The spray angle of the nozzle on the spray gun is adjusted according to actual needs before spraying, and the second motor 14 is controlled to drive the screw rod 15 at the output end to rotate, thereby driving the sliding ring 18 to pull multiple connecting plates 19 to move up and down, and at the same time drive multiple connecting blocks 20 to flip on the mounting table 21, so as to adjust the angle of the spray gun 22 to achieve the spraying angle of the appropriate material specifications.

[0019] like Figure 2 and 3 As shown, the transmission mechanism includes a driven wheel 8, which is installed on the feed pipe 7. A driving wheel 9 is meshingly installed on one side of the driven wheel 8. A first motor 10 is installed at the bottom of the driving wheel 9. The first motor 10 is installed on the protective shell 5. The driven wheel 8 in the transmission mechanism cooperates with the driving wheel 9 to drive the feed pipe 7 to rotate, so that the spraying is uniform.

[0020] like Figure 3 and 4 As shown, in order to facilitate the adjustment of the spray angle of the spray gun 22, the lifting linkage mechanism includes a screw rod 15, the screw rod 15 is rotatably installed inside the hollow plate 16, the upper end of the screw rod 15 is fixed to the output end of the second motor 14, and the rod wall of the screw rod 15 is threadedly installed with a screw block 17, and a sliding ring 18 is installed on the screw block 17. A plurality of connecting plates 19 are rotatably installed on the sliding ring 18, and the rotation angle of the plurality of connecting blocks 20 is limited by the sliding ring 18, thereby greatly improving the stability of the equipment operation, and one side of the plurality of connecting plates 19 is rotatably installed with a connecting block 20, and the plurality of spray guns 22 are respectively installed on the corresponding connecting blocks 20, and the lifting linkage mechanism also includes a mounting platform 21, one side of the plurality of connecting blocks 20 is rotatably installed on the mounting platform 21, and one side of the mounting platform 21 is installed on the hollow plate 16, and the moving position of the connecting plate 19 is limited by the hollow plate 16.

[0021] like Figure 3 and 5As shown, the sliding ring 18 is slidably installed inside the hollow plate 16, and two limit rods 29 are installed on the top of the protective shell 5. The upper ends of the two limit rods 29 pass through the casing 2 and extend to the outside. The limit rods 29 arranged on both sides limit the moving position of the transmission mechanism and the lifting linkage mechanism, so that the operation is more stable. Two mounting plates 30 are installed on the protective shell 5, and a protective box 31 is commonly installed on one side of the two mounting plates 30. Multiple spray guns 22 are arranged inside the protective box 31. The protective box 31 is installed on the protective shell 5 through the mounting plate 30 to protect the spray gun 22.

[0022] The working principle is as follows: before actual use, the spray angle of the nozzle on the spray gun 22 can be adjusted according to actual needs. When in use, the cylinder 3 is first started so that its output end pushes the fixed platform 4 to move downward, thereby driving the protective shell 5, the rotating block 6, the feed pipe 7, the feed box 11, the fixed shell 13, the hollow plate 16 and other components to descend as a whole. At the same time, the first motor 10 is started to drive the driving wheel 9 to rotate. The driving wheel 9 rotates the driven wheel 8 through meshing transmission, thereby driving the feed pipe 7 to rotate in the rotating block 6. The feed pipe 7 receives the spray material through the delivery pipe and delivers it to the feed box 11. The second motor 14 is started to drive the screw rod 15 to rotate in the hollow plate 16, so that the screw block 17 moves on the screw rod 15, thereby driving the sliding ring 18 to slide in the hollow plate 16. The movement of the sliding ring 18 drives the connecting block 20 to move through the multiple connecting plates 19, thereby adjusting the position of the spray gun 22. The mounting table 21 provides support and rotation connection points for the connecting block 20 to ensure the stable movement of the spray gun 22. This technical solution achieves uniform spraying of the surface of the fastener through the coordinated work of various components, thereby improving the spraying efficiency and quality.

[0023] Example 2: Figure 2 and 5 As shown, in order to make the spray process more convenient, a fixed rod 24 is installed at the bottom of the spraying table 23, and a protective cover 25 is rotatably installed on the rod wall of the fixed rod 24. A third motor 26 is installed inside the protective cover 25, and the output end of the third motor 26 is fixed to the lower end of the fixed rod 24. An electric slide rail 27 is installed at the bottom of the protective cover 25, and an electric slider 28 is slidably installed on the outer wall of the electric slide rail 27. On the spraying table 23, the third motor 26 is started to drive the protective cover 25 to rotate on the fixed rod 24. At the same time, the electric slide rail 27 and the electric slider 28 cooperate to achieve all-round spraying of the fasteners. After the spraying is completed, the electric slide rail 27 is driven to move by controlling the electric slider 28, thereby driving the material above it to move together, so as to facilitate the removal of the material out of the equipment and facilitate subsequent operations.
