It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 4 A paint spraying device for a transmission shaft, the paint spraying device for the transmission shaft comprises: a bracket 1, a rotating shaft 2, a motor 3, a movable box 4, a rotating rod 5, a hanging sleeve 6, a receiving rod 7, a transmission rod 8 and a spray gun 9, the upper part of the bracket 1 is internally rotatably connected with the rotating shaft 2, a motor 3 is installed on one side of the bracket 1, the output end of the motor 3 is fixedly connected to the end corresponding to the rotating shaft 2, a high-strength rubber roller 10 is sleeved on the outer side of the rotating shaft 2, an movable box 4 is equidistantly arranged inside the bracket 1, a groove is opened on one side of the movable box 4, and the groove is sleeved on the outer side of the rotating shaft 2, a rotating rod 5 is rotatably connected inside the movable box 4, and a hanging sleeve 6 is fixedly connected to the bottom end of the rotating rod 5, and the hanging sleeve 6 A notch is provided on one side of the bottom, and original blank transmission shafts 11 are equidistantly provided inside the bracket 1. The top ends of the original blank transmission shafts 11 are respectively embedded in the corresponding suspension sleeves 6. A receiving rod 7 is symmetrically rotatably connected inside the bracket 1, and a wide rubber roller 12 is sleeved on the outside of the receiving rod 7. A transmission rod 8 is rotatably connected inside the bracket 1, and a worm 13 is fixedly connected to the outside of the transmission rod 8. A worm gear 14 is fixedly connected to the outside of the rotating rod 5, and the worm 13 is meshingly connected to the worm gear 14. A thin rubber roller 15 is symmetrically sleeved on the outside of the transmission rod 8. Both the wide rubber roller 12 and the thin rubber roller 15 are squeezed and fitted with the high-strength rubber roller 10. A spray gun 9 is provided on one side of the bracket 1.

[0022] It should be noted that: the motor 3 drives the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, the high-strength rubber roller 10 on its outside starts to rotate. The high-strength rubber roller 10 fits tightly with the wide rubber roller 12 and the thin rubber roller 15. Therefore, when the high-strength rubber roller 10 rotates, it will drive the wide rubber roller 12 and the thin rubber roller 15 to rotate together. The rotation of the wide rubber roller 12 and the thin rubber roller 15 further drives the receiving rod 7 and the transmission rod 8 to rotate. On the outside of the transmission rod 8, the worm 13 is meshed with the worm wheel 14. When the transmission rod 8 rotates, the worm 13 on its outside will drive the worm wheel 14 to rotate. When the worm wheel 14 rotates, the rotating rod 5 will also rotate accordingly. The rotation of the rotating rod 5 eventually rotates the original blank drive shaft 11 in the suspension sleeve 6 in each movable box 4. During the painting process, the spray gun 9 sprays the rotating original blank drive shaft 11 at an appropriate position to achieve the effect of spraying while rotating.

[0023] See also Figures 1 to 4 , two receiving rods 7 and a transmission rod 8 inside the movable box 4 are distributed in a circular array around the rotating shaft 2;

[0024] It should be noted that: when the rotating shaft 2 is rotated, the movable box 4 can be slidably connected to the outside of the rotating shaft 2;

[0025] See also Figures 1 to 4 A guide rod 16 is fixedly connected to the inside of the bracket 1 above the rotating shaft 2, and a positioning piece 17 is provided on the top of the movable box 4. The top of the positioning piece 17 is bent, and the bending part of the positioning piece 17 is slidably connected to the outside of the guide rod 16;

[0026] It should be noted that: this ensures that the movable box 4 can remain relatively still when the rotating shaft 2 rotates, and allows the movable box 4 to slide along the guide rod 16 to adjust the spacing between adjacent movable boxes 4;

[0027] See also Figures 1 to 4 , a push handle 18 is fixedly connected to the other side of the bracket 1;

[0028] It should be noted that: it is used to conveniently push and move the entire device, thereby improving the portability and operational flexibility of the device;

[0029] See also Figures 1 to 4 , universal wheels 19 are installed at the four corners of the bottom of the bracket 1;

[0030] It should be noted that: these universal wheels 19 not only make the entire device easy to move and transfer between different work sites, but also improve the stability and flexibility of the device during the spraying operation. Through the universal wheels 19, the operator can easily adjust the position and direction of the device;

[0031] See also Figures 1 to 4A storage box 20 is fixedly connected to one side of the bracket 1, and the spray gun 9 is placed inside the storage box 20;

[0032] It should be noted that the storage box 20 is used to store and accommodate the spray gun 9. By placing the spray gun 9 inside the storage box 20, not only can the spray painting site be kept clean, but also the operator can conveniently take the spray gun 9 at any time, thereby improving the efficiency of the spray painting operation;

[0033] See also Figures 1 to 4 The inner wall of the notch of the suspension sleeve 6 is symmetrically fixedly connected with a rubber ball 21;

[0034] It should be noted that the provision of the rubber balls 21 can increase the friction between the suspension sleeve 6 and the transmission shaft, preventing the transmission shaft from sliding or deflecting during the painting process, thereby ensuring the accuracy and uniformity of the painting.

[0035] The working principle of the paint spraying device of the transmission shaft provided by the utility model is as follows: the motor 3 drives the rotating shaft 2 to rotate. When the rotating shaft 2 rotates, the superior rubber roller 10 on its outer side starts to rotate. The superior rubber roller 10 is tightly fitted with the wide rubber roller 12 and the thin rubber roller 15. Therefore, when the superior rubber roller 10 rotates, it will drive the wide rubber roller 12 and the thin rubber roller 15 to rotate together. The rotation of the wide rubber roller 12 and the thin rubber roller 15 further drives the receiving rod 7 and the transmission rod 8 to rotate. On the outer side of the transmission rod 8, the worm 13 is meshed with the worm wheel 14. When the transmission rod 8 rotates, the worm 13 on its outer side will drive the worm wheel 14 to rotate. When the worm wheel 14 rotates, the rotating rod 5 will also rotate accordingly. The rotation of the rotating rod 5 eventually rotates the original blank transmission shaft 11 in the suspension sleeve 6 in each movable box 4. During the painting process, the spray gun 9 sprays the rotating original blank transmission shaft 11 at an appropriate position to achieve the effect of spraying while rotating.

[0036] The design of the suspension sleeve 6 makes it convenient and quick to take and put the original drive shaft 11. The operator can easily put the original drive shaft 11 into or take it out of the suspension sleeve 6 to perform continuous painting operations. In addition, the rubber balls 21 symmetrically fixedly connected to the inner wall of the notch of the suspension sleeve 6 provide additional support and stability to prevent the original drive shaft 11 from shaking or displacement during the painting process.

[0037] The movable box 4 is slidably connected to the guide rod 16 in the bracket 1 through the positioning piece 17 on its top, ensuring that the movable box 4 remains stationary when the shaft 2 rotates, and the movable box 4 can slide on the outside of the shaft 2, thereby changing the spacing between adjacent movable boxes 4. This flexibility enables the device to adapt to the painting needs of original drive shafts 11 of different sizes and quantities, and the movable box 4 is clamped on the outside of the shaft 2 by the wide rubber roller 12 and the thin rubber roller 15. The wide rubber roller 12 and the thin rubber roller 15 have a certain deformation ability, and the movable box 4 can be pulled off from the outside of the shaft 2 by external force, so that it is convenient for maintenance and replacement.
