[0002] Surface coating is a crucial process in industrial production, ensuring the corrosion resistance of workpieces, extending their service life, and enhancing their appearance. It is widely used in the processing of various products such as automotive parts, hardware products, and machinery. As the manufacturing industry transforms towards automation and efficiency, suspended painting production lines, with their advantages of continuous workpiece transport and automated painting operations, are gradually becoming core equipment for large-scale coating production. Through a transmission structure, they drive workpiece hooks, moving the workpieces sequentially through the painting area, achieving a streamlined painting process. This significantly reduces manual labor intensity and improves production efficiency and coating consistency.

[0003] However, existing suspended painting production lines still have significant technical shortcomings in practical applications, which limit their applicability and production efficiency: the installation spacing of workpiece hooks is mostly fixed, and the left and right spacing cannot be flexibly adjusted according to the width, shape, and batch requirements of the workpieces to be processed. When processing workpieces of different sizes, it is necessary to disassemble and replace the appropriate hook assembly or make overall adjustments to the transmission structure, which is cumbersome and time-consuming. This not only increases production preparation time and labor costs, but also limits the applicability of the equipment and makes it difficult to adapt to the processing needs of a variety of workpieces.

[0021] refer to Figure 4 The painting mechanism 3 includes a liquid pump 31, the inlet of which is connected to a liquid pump pipe 32, the end of which is away from the liquid pump 31 and connected to a paint storage tank 104, the outlet of which is connected to a liquid outlet pipe 33, the end of which is away from the liquid pump 31 and passes through the painting machine housing 105 and extends into the interior of the painting machine housing 105 and is connected to a connecting pipe 34, the inner side of which is connected to a spray nozzle 35.

[0022] As a technical optimization of this utility model, by setting up a painting mechanism 3, the paint can be sprayed evenly.

[0023] refer to Figure 1 The bottom of the base 101 is fixedly connected to a support leg, and the bottom of the surface of the support rod 102 is fixedly connected to a reinforcing plate 7. The bottom of the reinforcing plate 7 is fixedly connected to the top of the base 101.

[0024] As a technical optimization of this utility model, by setting the reinforcing plate 7, the connection strength between the support rod 102 and the base 101 is greatly enhanced, avoiding structural loosening caused by vibration during long-term operation; by setting the support legs, the overall stability of the equipment is further improved, preventing the equipment from shaking during the painting operation, which not only ensures the painting accuracy of the nozzle 35, but also extends the service life of the equipment.

[0025] refer to Figure 3 Both sides of the surface of the positive and negative threaded rod 43 are fixedly connected to fixed bearings 8, and the surface of the outer ring of the fixed bearing 8 is fixedly connected to the inner wall of the connecting shell 41.

[0026] As a technical optimization of this utility model, by setting a fixed bearing 8, the positive and negative threaded rods 43 are fixed to avoid the rods from deviating or jamming, ensuring that the positive and negative threaded rods 43 rotate stably and uniformly, thereby driving the screw sleeve 44 and the sliding plate 45 to move smoothly, improving the smoothness and accuracy of the left and right spacing adjustment of the hook, and ensuring the accuracy of the spacing adaptation of workpieces of different sizes.

[0027] refer to Figure 3 The bottom of the connecting shell 41 is provided with sliding grooves 9 on both sides, and a slider is slidably connected inside the sliding groove 9. The inner side of the screw sleeve 44 is fixedly connected to the slider.

[0028] As a technical optimization of this utility model, by setting the slide groove 9 and the slider, the movement of the screw sleeve 44 can be guided and limited, preventing the screw sleeve 44 from shifting circumferentially with the rotation of the positive and negative threaded rods 43, ensuring that the sliding plate 45 always moves in a straight line, making the left and right distance adjustment of the hook more accurate, and avoiding workpiece collision or uneven painting due to distance deviation.

[0029] refer to Figure 5 Guide blocks 10 are fixedly connected to both sides of the slide plate 52, and guide grooves 11 are opened on both sides inside the connecting sleeve 51. The guide blocks 10 are slidably connected to the guide grooves 11.

[0030] As a technical optimization of this utility model, by setting the guide block 10 and the guide groove 11, a stable guide can be provided for the lifting and lowering movement of the slide plate 52 and the lifting rod 53, so as to avoid deviation or jamming during the lifting and lowering process.

[0031] The working principle and usage process of this utility model are as follows: In use, firstly, according to the width requirement of the workpiece to be processed, the operator rotates the rotating disk 42 of the left and right adjustment mechanism 4 of the hook, causing the left-side positive and negative threaded rod 43 to rotate stably under the support of the fixed bearing 8. Since the thread directions on both sides of the positive and negative threaded rod 43 are opposite, and the threaded sleeve 44 slides with the sliding groove 9 at the bottom of the connecting shell 41 through the inner slider, the threaded sleeve 44 will not rotate with the threaded rod, but will move linearly closer or further away from each other along the sliding groove 9. This, in turn, causes the fixedly connected sliding plate 45 to extend or retract, realizing the left and right movement of the workpiece hooks 6 on both sides. The height can be flexibly adjusted to accommodate the mounting needs of workpieces of different widths. For workpiece height differences, loosen the connecting bolt 54 of the hook lifting adjustment mechanism 5, push the lifting rod 53 to drive the slide plate 52 to slide inside the connecting sleeve 51. At this time, the guide blocks 10 on both sides of the slide plate 52 move smoothly along the guide grooves 11 on the inner wall of the connecting sleeve 51, ensuring accurate lifting direction without deviation. After adjusting to the optimal painting height, tighten the connecting bolt 54 so that it passes through the connecting sleeve 51 and embeds into the slide plate 52, locking the position of the slide plate 52, thus completing the height positioning of the workpiece hook 6. Then, start the motor 21 of the transmission structure 2; the output end of the motor 21 drives the gears. When gear 22 rotates, gear 22 meshes with gear 23, which in turn drives the transmission shaft 24 on the left side of gear 23 to rotate. The transmission shaft 24 and the rotating rod 25 inside the connecting plate 103 rotate synchronously through bearings, and the transmission belt 26 sleeved on its surface runs at a uniform speed. Since the connecting shell 41 of the hook left and right adjustment mechanism 4 is fixedly connected to the transmission belt 26, the transmission belt 26 drives the connecting shell 41, the hook lifting and adjusting mechanism 5 and the workpiece hook 6 that hangs the workpiece to move continuously along both sides of the paint spraying machine box 105, so that the workpiece enters the paint spraying area in an orderly manner, providing power guarantee for automated continuous coating; when the workpiece is carried by the transmission... When the conveyor belt 26 moves into the paint spraying machine housing 105, the liquid pump 31 of the paint spraying mechanism 3 is started. The liquid pump 31 draws paint from the paint storage tank 104 at the top of the base 101 through the liquid extraction pipe 32, and delivers it to the connecting pipe 34 inside the paint spraying machine housing 105 through the liquid outlet pipe 33. Then, the paint is sprayed onto the workpiece through the nozzle 35 inside the connecting pipe 34. Since the workpiece has been accurately positioned to the optimal painting position by the left and right adjustment mechanism 4 and the lifting adjustment mechanism 5 of the hook, and the conveyor belt 26 maintains a uniform speed, the paint sprayed by the nozzle 35 can cover the surface of the workpiece, ensuring a consistent coating thickness and improving the coating quality.

[0032] In summary, this suspended spray painting production line, through the integration of the left-right adjustment mechanism 4 and the lifting adjustment mechanism 5, solves the problems of fixed hook spacing and inconvenient height adjustment in existing suspended spray painting production lines. The positive and negative threaded rods 43 drive the screw sleeves 44 and sliding plates 45 to flexibly adjust the left-right spacing of the hooks. The connecting sleeves 51, sliding plates 52 and connecting bolts 54 work together to achieve precise adjustment of the hook height. It can adapt to workpieces of different widths and heights without disassembling or replacing components, greatly expanding the applicability of the equipment, reducing production preparation time and labor costs, while ensuring that the workpiece is in the optimal painting position and improving the consistency of coating quality.
