[0026] 3. This multi-color gradient spraying equipment suitable for wheel hub painting can fix the wheel hub on the vertical plate before spraying through the provided vertical plate and clamping assembly. The locking thread of the positioning rod enhances the fixing effect, prevents the wheel hub from shaking or shifting during the spraying process, and ensures the spraying accuracy.

[0027] 4. This multi-color gradient spraying equipment suitable for wheel hub painting is equipped with a paint barrel, paint tank, paint tube and observation panel, which allows operators to check the remaining paint at any time and replenish the paint in time to avoid affecting the spraying work due to insufficient paint and improve work efficiency.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1-5 A multi-color gradient spraying device suitable for wheel hub painting includes a base frame 1 and a support column 2 fixed to the outer wall of the base frame 1, a vertical plate 3 is fixed on the top of the base frame 1, and a clamping assembly is provided on the outer wall of the vertical plate 3 for clamping the wheel hub;

[0037] A barrel 4 is fixedly provided at the lower end of the outer wall of the support column 2, and a plurality of paint troughs 5 are arranged symmetrically around the top of the barrel 4. The barrel 4 is installed at the lower end of the outer wall of the support column 2, and the plurality of paint troughs 5 arranged symmetrically around the top are used to store paints of different colors and provide raw materials for multi-color gradient spraying. Each paint trough is independent of each other to prevent mixing of paints of different colors. An observation panel 15 is fixedly embedded in the trough wall of each paint trough 5. The observation panel 15 is a transparent visual observation panel. The transparent visual observation panel fixedly embedded in the trough wall of each paint trough 5 is convenient for the operator to observe the remaining paint in the paint trough 5 at any time. During the spraying operation, the operator can promptly discover the lack of paint so as to replenish the paint in time to avoid affecting the continuity and effect of the spraying work due to paint shortage. A paint pipe 6 is fixedly provided on the inner wall of the paint trough 5, and the plurality of paint pipes 6 are high-pressure soft The tube has good flexibility and can adapt to the spraying needs of the nozzle 8 at different positions and angles. The tube wall of each paint tube 6 is fixedly sleeved with a pump body 7, and multiple pump bodies 7 are arranged in parallel. The pump body 7 is fixedly arranged on the top of the barrel 4, and the pipe mouths of multiple paint tubes 6 are connected with nozzles 8. The upper ends of the outer walls of the multiple paint tubes 6 are commonly fixedly sleeved with a connecting plate 9. The inner part of the connecting plate 9 is rotatably penetrated with a cross bar 10. The inner wall of the support tube 13 is fixedly embedded with a damping sleeve 21. The cross bar 10 is rotatably arranged in the damping sleeve 21. The end of the cross bar 10 is fixedly provided with a cover plate 11. The cover plate 11 is provided with a spray port 12 inside and contacts the outer wall of the multiple nozzles 8. When the cross bar 10 rotates, it drives the cover plate 11 to rotate, and the different nozzles 8 are sequentially aligned through the spray port 12 to realize the sequential spraying of multiple paints, thereby completing the multi-color gradient spraying effect on the surface of the wheel hub;

[0038] The rod wall of the crossbar 10 is sleeved with a support tube 13, and two symmetrically arranged connecting rods 14 are fixed between the pipe opening of the support tube 13 and the connecting plate 9;

[0039] A one-way shifting assembly is provided between the cross bar 10 and the support column 2. The one-way shifting mechanism is used to open multiple nozzles 8. The one-way shifting mechanism assembly includes a support plate 16, which is fixed to the upper end of the outer wall of the support column 2, and the outer wall is fixed with a plurality of spaced mounting blocks 17. The end of the mounting block 17 is provided with a ratchet 18 through an axle pin rotation. A spring 19 is fixed between the ratchet 18 and the support plate 16. The bottom contact of the ratchet 18 is provided with a limit plate 20, and the limit plate 20 is fixedly connected to the support plate 16. The rod wall fixing sleeve of the cross bar 10 is provided with a ratchet 27, and the ratchet 27 is cooperated with the ratchet 18. When the cross bar 10 rotates, the ratchet 18 pushes the ratchet 27 to rotate unidirectionally, thereby driving the cross bar 10 and the cover plate 11 to rotate, so that the spray port 12 is aligned with different nozzles 8 in sequence, and the nozzles 8 are opened in sequence for spraying, ensuring the orderly progress of multi-color gradient spraying.

[0040] Example 2

[0041] Example 2 is based on Example 1 in order to enable multiple nozzles 8 to move longitudinally and spray at the same time, so that the one-way transposition component can operate stably. Figure 1-3 and Figure 5 As shown, a strip hole is provided at the inner upper end of the support column 2, and a reciprocating screw rod 22 is rotatably inserted in the strip hole. A slider 23 is threadedly sleeved on the rod wall of the reciprocating screw rod 22, and the outer wall of the slider 23 contacts and cooperates with the inner wall of the strip hole. The slider 23 is fixedly sleeved on the outside of the support tube 13, and a control motor 24 is fixedly provided at the lower end of the back side of the support column 2. The output shaft end of the control motor 24 and the lower end of the reciprocating screw rod 22 are fixedly sleeved with a synchronous wheel 25. The outer sides of the two synchronous wheels 25 are driven by a synchronous belt 26. The control motor 24 is installed at the lower end of the back side of the support column 2. After starting, the synchronous wheel 25 is driven to rotate by the output shaft, and the synchronous wheel 25 then drives the reciprocating screw rod 22 to rotate through the synchronous belt 26.

[0042] Example 3

[0043] Example 3 is based on Example 1 to ensure the stability of the wheel hub spraying process. Figure 1 As shown, the clamping assembly includes a positioning rod 28, which is fixed to the middle of the outer wall of the vertical plate 3, and a locking nut 29 is provided on the threaded sleeve of the rod wall. A locking thread is provided on the outer side of one end of the positioning rod 28 close to the locking nut 29. The positioning rod 28 passes through the mounting hole of the wheel hub. By tightening the locking nut 29 and utilizing the locking thread on the positioning rod 28, the wheel hub is firmly fixed to the vertical plate, ensuring that the wheel hub will not shake or move during the spraying process, thereby ensuring the spraying accuracy.

[0044] In summary, the multi-color gradient spraying equipment suitable for wheel hub painting, when in use, first place the wheel hub to be sprayed on the positioning rod 28, and rotate the locking nut 29 so that the locking nut 29 cooperates with the locking thread to stably clamp the wheel hub, and then determine the position of the wheel hub, and then pour different colors of paint into the corresponding paint tank 5 respectively, and confirm the amount of paint through the observation plate 15, and then start the control motor 24, and the control motor 24 drives the reciprocating screw 22 to rotate through the synchronous wheel 25 and the synchronous belt 26, so that the slider 23 and the support tube 13, the cross bar 10, etc. move up and down along the strip hole, so that the multiple nozzles 8 can move longitudinally and start spraying the wheel hub;

[0045] Then open multiple pump bodies 7. At this time, since the spray port 12 of the cover plate 11 is only aimed at one nozzle 8, the nozzle 8 starts to spray. At the same time, since the support tube 13 moves upward, the ratchet 18 of the one-way shifting assembly only contacts the ratchet 27 under the action of the spring, and cannot push the ratchet 27. When one color is sprayed, the ratchet 27 moves up to the highest point and separates from the ratchet 18. Then the support tube 13 starts to move down. At this time, under the support of the limit plate 20, the ratchet 17 cannot rotate and starts to push the ratchet 27, so that the ratchet 27 starts to drive the cross bar 10 to rotate and drive the cover plate 11 to rotate, so that the paint port 12 rotates to the front of the other nozzle 8 and starts to cover the spraying of another color, thereby completing the gradual spraying of the wheel hub and improving the spraying effect.
