[0019] (III) Beneficial effects

[0020] The present invention provides a sports equipment painting device, which has the following beneficial effects:

[0021] 1. By fixing the top and bottom ends of the pipe fitting on the fastening seats on the upper and lower sides, the spline shaft can be driven to move axially inside the spline cylinder by rotating the upper and lower adjustment rings during the movement of the upper movable plate to the right and the lower movable plate to the left. Therefore, the length of the telescopic spline shaft cylinder composed of the spline shaft and the spline cylinder can be adjusted according to the distance the upper movable plate moves to the right and the distance the lower movable plate moves to the left. Therefore, the top end of the pipe fitting can be deflected to the lower right and the bottom end of the pipe fitting can be deflected to the upper left. Therefore, the pipe fitting can be placed at an angle so that the surface of the inclined pipe fitting can be evenly sprayed with paint later.

[0022] 2. In the process of rotating the upper and lower adjustment rings to adjust the length of the telescopic spline shaft cylinder composed of the spline shaft and the spline cylinder, the spiral scraper can be lengthened or shortened so that the spiral scraper can match the surface curve of the pipe fitting and leave a certain gap between the spiral scraper and the pipe fitting. At this time, the top end of the spiral scraper is located at the upper left of the pipe fitting, and the bottom end of the spiral scraper is located at the lower right of the pipe fitting. In the process of slow rotation of the pipe fitting, the excess paint on the surface of the pipe fitting can be scraped off by the spiral scraper, so that the paint thickness on the surface of the pipe fitting is more uniform.

[0023] 3. When the paint spraying plate and the pipe fittings are parallel to each other, the distances from multiple sets of paint spraying valves to the surface of the pipe fittings can be made equal. The paint spraying pipe and the paint spraying pump can transport the paint liquid to the paint spraying valves at different positions. During the slow rotation of the pipe fittings, the paint spraying valves at different positions will evenly spray the paint liquid on the surface of the pipe fittings. When the drying plate and the pipe fittings are parallel to each other, the distances from multiple sets of air outlet valves to the surface of the pipe fittings can be made equal. At the same time, the hot air blower can transport hot air to the air outlet valves at different positions and dry the surface of the pipe fittings quickly and evenly.

[0053] Specifically, the hot air blower 802 can transport the hot air to the air outlet valves 803 at various positions through the drying pipe network, so that the air outlet valves 803 can evenly dry the surface of the pipe 415 .

[0054] The working principle and use process of the present invention are as follows: the top end of the pipe 415 is sleeved on the outside of the upper fastening seat 413, the bottom end of the pipe 415 is sleeved on the outside of the lower fastening seat 413, and then the three groups of clamping electric rods 414 at the upper and lower ends are stretched to resist the inner wall of the pipe 415, and the top and bottom ends of the pipe 415 are fixed to the fastening seats 413 on the upper and lower sides, and then the top and bottom ends of the spiral scraper 419 are fixed to the upper and lower groups of rotating rings 418 by bolts, and the spiral scraper 419 is a high damping composite The driving motor 301 is made of gold and has a certain weight. The upper and lower sets of driving bevel gears 303 are driven to rotate through the driving shaft 302, and the upper and lower sets of screw shafts 304 can rotate in opposite directions through the meshing of the driving bevel gears 303 and the driven bevel gears 305. Then, the upper screw shaft 304 can drive the upper moving plate 402 to move rightward through the upper bracket 403, and the lower screw shaft 304 can drive the lower moving plate 404 to move leftward through the lower bracket 405. At the same time, the upper moving plate 402 moves rightward to In the process of the lower movable plate 404 moving to the left, the spline shaft 411 can be driven to move axially inside the spline cylinder 412 by rotating the upper and lower adjustment rings 416. Therefore, the length of the telescopic spline shaft cylinder composed of the spline shaft 411 and the spline cylinder 412 can be adjusted according to the distance the upper movable plate 402 moves to the right and the distance the lower movable plate 404 moves to the left. Therefore, the top end of the pipe fitting 415 can be deflected to the lower right and the bottom end of the pipe fitting 415 can be deflected to the upper left. Therefore, the pipe fitting 415 can be placed at an angle, and In the process of rotating the upper and lower adjustment rings 416 to adjust the length of the telescopic spline shaft cylinder composed of the spline shaft 411 and the spline cylinder 412, the spiral scraper 419 can be lengthened or shortened, so that the spiral scraper 419 is adapted to the surface curve of the pipe 415, and a certain gap is left between the spiral scraper 419 and the pipe 415. At this time, the top end of the spiral scraper 419 is located at the upper left of the pipe 415, and the bottom end of the spiral scraper 419 is located at the lower right of the pipe 415. Then, the upper and lower adjustment motors 409 are started at the same time.The universal joint 410 is driven to rotate slowly. The universal joint 410 can drive the pipe 415 to rotate slowly through the spline shaft 411, the spline cylinder 412 and the clamping electric rod 414. During this process, the adjusting ring 416 also rotates. Because the top and bottom ends of the spiral scraper 419 are respectively connected to the upper and lower adjustment rings 416 through the rotating ring 418, the spiral scraper 419 will not be driven to rotate during the rotation of the adjusting ring 416, so that the top of the spiral scraper 419 is always at the upper left of the pipe 415, and the bottom is always at the pipe 41 5, and then start the upper electric rod 5 and the lower electric rod 6 on the left and right sides respectively, and the upper electric rod 5 and the lower electric rod 6 on the left and right sides can drive the paint spraying plate 701 and the drying plate 801 to deflect, so that the paint spraying plate 701 and the drying plate 801 are parallel to the inclined pipe 415, and when the paint spraying plate 701 and the pipe 415 are parallel to each other, the distances from the multiple sets of paint spraying valves 704 to the surface of the pipe 415 can be equal, and at this time, the paint spraying pipe 703 and the paint spraying pump 702 can transport the paint liquid to the paint spraying valves 704 at different positions. 4. During the slow rotation of the pipe 415, the paint spraying valves 704 at different positions evenly spray the paint liquid on the surface of the pipe 415. After the paint liquid is sprayed on the surface of the pipe 415, during the rotation of the pipe 415, the paint liquid on the surface of the pipe 415 can flow along the surface of the pipe 415 to the lower right end thereof, and finally drip onto the slope 406. The paint liquid on the slope 406 flows along the slope 406 to the storage tank 407, and the paint liquid is discharged through the through hole 408 and collected together, so that the paint liquid can be reused. Recycling, and in the process of painting the pipe 415, the spiral scraper 419 can scrape off the excess paint on the surface of the pipe 415, so that the paint thickness on the surface of the pipe 415 is more uniform, and when the drying plate 801 and the pipe 415 are parallel to each other, the distances from the multiple groups of air outlet valves 803 to the surface of the pipe 415 can be equal, and the hot air blower 802 can deliver hot air to the air outlet valves 803 at different positions, and quickly and evenly dry the surface of the pipe 415, so that the surface of the pipe 415 after painting is more uniform and smooth.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
