[0002] The coating spraying process in the production of metal materials is an important surface treatment technology, which aims to improve the corrosion resistance, wear resistance, decorativeness and other functional characteristics of metal materials. The coating spraying process is to spray specific coating materials evenly onto the surface of metal materials through spraying equipment to form a dense coating layer. This coating layer can isolate the metal from the outside world and play a role in corrosion resistance, oxidation resistance, and wear resistance, thereby improving the overall performance and service life of metal materials; The traditional coating spraying process is cumbersome, involving multiple steps and the coordinated work of components. The operation is relatively complex and often relies on a large amount of manual operation, requiring operators to have a high level of technical skills and experience.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely introduced below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] For example, see Figure 1-12 , a coating spraying process for metal material production, the process is as follows: First, the metal pipe 9 to be processed is placed on the plug rod 22 between the first fixed frame 41 and the third fixed frame 61, and the driving motor 33 is started at the same time, so that the driving motor 33 drives the rotating disk 34 to rotate, and the rotating disk 34 drives the synchronous connecting rod 35 to move, so that the synchronous connecting rod 35 pulls the sliding plate 36 to slide up and down between the two limiting frames 32, and the connecting block 38 slides left and right between the two sliding limiting plates 37 under the action of the inclined groove on the sliding plate 36; When the connecting block 38 slides, when the arc surface of the toggle block 39 on the connecting block 38 contacts the teeth on the synchronous gear 25, the toggle block 39 will be retracted into the connecting block 38 under the push of the synchronous gear 25. At this time, the connecting block 38 will not drive the synchronous gear 25 to rotate when it moves. When the connecting block 38 slides in the opposite direction driven by the sliding plate 36, the toggle block 39 pops out from the connecting block 38 under the action of the compression spring. At this time, the vertical surface of the toggle block 39 is engaged with the teeth on the synchronous gear 25, so that the toggle block 39 cannot be retracted into the connecting block 38. When the connecting block 38 slides in the opposite direction, the toggle block 39 pushes the synchronous gear 25 to rotate, so that the synchronous gear 25 drives the processing table 21 to rotate, and the processing table 21 drives the metal pipe 9 to move to the first fixed frame 41; When the metal tube 9 moves to the first fixed frame 41, the suction machine is started. When the metal tube 9 moves, it gradually contacts with the multiple cleaning brushes 42 on the first fixed frame 41, so that some dust and debris on the surface of the metal tube 9 are swept down by the cleaning brushes 42. The swept debris is transported to the dust box 44 through the conveying pipe 43 for centralized collection. At the same time, the metal tube 9 originally in the first fixed frame 41 is rotated to the second fixed frame 51 for coating spraying. When the metal tube 9 moves to the second fixed frame 51, the servo motor 53 and the feeder 59 are started, so that the servo motor 53 drives the synchronous screw 54 to rotate, and the sprayer 55 drives the spray head 56 to slide up and down under the action of the synchronous screw 54. At the same time, the feeder 59 transports the paint in the paint storage box 58 to the spray head 56 through the connecting pipe 57, and the paint is sprayed on the surface of the metal tube 9 through the spray head 56. The paint can be evenly sprayed on the metal tube 9 by the up and down movement of the spray head 56; At the same time, when the servo motor 53 is started, the servo motor 53 drives the second transmission gear 73 to rotate at the same time, so that the second transmission gear 73 drives the rotating ring 71 and the second gear ring 74 to rotate through the first gear ring 72. When the second gear ring 74 rotates, it drives the plurality of first transmission gears 23 to rotate, so that the first transmission gear 23 drives the plug-in rod 22 to rotate, so that the plug-in rod 22 in the first fixing frame 41 and the second fixing frame 51 drives the metal pipe 9 to rotate. When the metal pipe 9 in the first fixing frame 41 rotates, it can continuously contact with the cleaning brush 42 to make the cleaning more thorough. When the metal pipe 9 in the second fixing frame 51 rotates, it can cooperate with the up and down movement of the nozzle 56 to make the spraying more uniform and comprehensive. When the metal tube 9 has completed the spray coating work in the second fixing frame 51, the synchronous gear 25 drives the processing table 21 to rotate again, so that the metal tube 9 in the first fixing frame 41 is rotated to the second fixing frame 51 for spray coating, and the metal tube 9 in the second fixing frame 51 is moved to the first fixing frame 41, and the heating box 64 and the fan 65 are started. The air transported by the fan 65 is heated by the heating box 64, and the heated gas is transported to the drying plate 62 through multiple air ducts 63 and sprayed out to dry the coating on the metal tube 9; At the same time, when the second fixed frame 51 is working, the transmission assembly 7 is started again to make the metal tube 9 in the third fixed frame 61 rotate synchronously, so that the drying is faster and more thorough; When the drying is completed, the processing table 21 rotates again to continue the cycle, the metal tube 9 in the first fixed frame 41 is removed, and the worker removes the metal tube 9 from the plug-in rod 22 and inserts a new metal tube 9 into the plug-in rod 22.

A compression spring is also provided between the toggle block 39 and the inner wall of the connecting block 38. Specifically, when in use, after the metal tube 9 is placed on the plug rod 22, the driving motor 33 is first started, so that the driving motor 33 drives the rotating disk 34 to rotate, and when the rotating disk 34 rotates, the synchronous connecting rod 35 is simultaneously driven to move, so that the synchronous connecting rod 35 pulls the sliding plate 36 to slide up and down between the two limit frames 32, and the connecting block 38 slides left and right between the two sliding limit plates 37 under the action of the inclined groove on the sliding plate 36; When the connecting block 38 slides, when the arc surface of the toggle block 39 on the connecting block 38 contacts the teeth on the synchronous gear 25, the toggle block 39 will be retracted into the connecting block 38 under the push of the synchronous gear 25. At this time, the connecting block 38 will not drive the synchronous gear 25 to rotate when it moves. When the connecting block 38 slides in the opposite direction driven by the sliding plate 36, the toggle block 39 pops out from the connecting block 38 under the action of the compression spring. At this time, the vertical surface of the toggle block 39 is engaged with the teeth on the synchronous gear 25.
