[0024] Figures 1-4This invention illustrates a rotating structure for spraying the impeller of a liquefied gas compressor according to an embodiment of the present invention. It includes a rectangular box 1; a threaded rod 2 is rotatably connected to the inner wall of the rectangular box 1; a motor 3 is bolted to the surface of the rectangular box 1; an internally threaded hole block 4 is threaded to the surface of the threaded rod 2; a horizontal plate 5 is fixedly connected to the inner wall of the rectangular box 1; two symmetrically arranged limiting sleeves 6 are bolted to the bottom of the horizontal plate 5; a rack 7 is slidably connected to the inner wall of the limiting sleeves 6; a toothed plate 8 is rotatably connected to the bottom of the horizontal plate 5 via a rotating shaft; a shaft 9 passes through the top of the rectangular box 1; the bottom end of the shaft 9 passes through the rectangular box 1 and the horizontal plate 5 and is fixedly connected to a rotating plate 10; the bottom of the rotating plate 10 is fixed... A rotary shaft 11 is connected, and a carrier plate 13 is fixedly connected to the top of the shaft 9. An impeller 14 is placed on the inner wall of the carrier plate 13, and a rubber pad 15 is attached to the inner wall of the carrier plate 13. The rubber pad 15 is located below the impeller 14. The rubber pad 15 protects the inner wall of the carrier plate 13, preventing the impeller 14 from being damaged by the bottom of the inner cavity of the carrier plate 13 when it comes into direct contact with the carrier plate 13. It can also further increase the friction of the inner wall of the carrier plate 13, preventing the impeller 14 from shifting during the rotation of the carrier plate 13, thereby improving the accuracy of the impeller 14 being sprayed.

[0025] Working Principle: When using this invention, the user places the impeller 14 on the inner wall of the carrier plate 13. At this time, the spraying robot 17 moves on the surface of the slide rail 16 and performs spraying operations on the impeller 14. Simultaneously, the motor 3 is turned on to drive the threaded rod 2 to reciprocate, causing the threaded rod 2 to drive the internal threaded hole block 4 to reciprocate. Then, the internal threaded hole block 4 drives the toothed plate 8 to rotate through the rack 7. During this process, the movement of the rack 7 is limited by the setting of the limiting sleeve 6, ensuring the stability of the rack 7 during movement. Then, the toothed plate 8 drives the rotating plate 10 to rotate through the pivot shaft 11, which in turn drives the carrier plate 13 to rotate through the shaft 9. This causes the carrier plate 13 to drive the impeller 14 to rotate, so that the impeller 14 can be sprayed evenly. This achieves the rotation of the impeller during spraying, allowing the spraying angle of the impeller to be changed and adjusted, thereby improving the uniformity of the liquefied gas impeller spraying and further improving the yield of impeller spraying.

[0026] In summary, the rotating structure for spraying the impeller of this liquefied gas compressor uses the rotation of the threaded rod 2 to move the internal threaded hole block 4. This causes the internal threaded hole block 4 to rotate the toothed plate 8 via the rack 7. The toothed plate 8 then rotates the rotating plate 10 via the pivot shaft 11. The rotating plate 10 then rotates the carrier plate 13 via the shaft 9, which in turn causes the carrier plate 13 to rotate the impeller 14. This achieves the goal of rotating the impeller during spraying, allowing for adjustment of the spray angle, thereby improving the uniformity of the liquefied gas impeller spraying and further increasing the yield of good impeller coatings.
