[0024] In this technical solution, the hopper 2 allows for the storage of the required powder coating during the powder coating process. The fixed cylinder 7 seals the top of the hopper 2, preventing the powder coating material from scattering to the outside. Simultaneously, the worm gear 10, worm wheel 12, rotating shaft 11, and support frame 1 facilitate the collection of residual powder coating material from the hopper 2 into the fixed cylinder 7. Furthermore, the vibration motor 17, fixed frame 16, annular frame 19, and striking block 22 work together to vibrate and discharge the powder coating material from the side walls of the hopper 2 after the material coating is poured out. This allows the powder coating material adhering to the inner wall of the hopper 2 to be quickly removed, thus achieving the purpose of discharging and cleaning the powder coating material inside the hopper 2 during powder coating material replacement operations. The overall operation is convenient and quick, improving the efficiency of material replacement operations while facilitating daily work for personnel.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a spring 20 is fixedly connected to the surface of the guide rod 21, and the surface of the spring 20 contacts the surface of the annular frame 19. A support shaft 8 is fixedly connected to the upper left end of the outer surface of the compartment 2. The left side of the support shaft 8 is movably connected to the upper left end of the support frame 1 via a bearing. Brake casters 5 are movably connected to the bottom of the support frame 1 around its perimeter via bearings. A fixing cover 6 is fixedly connected to the upper right end of the support frame 1. The two ends of the worm gear 10 are movably connected to the inner cavity of the fixing cover 6 via bearings. Hooks 15 are fixedly connected to the upper ends of both sides of the outer surface of the compartment 2. Buckles 14 are fixedly installed at the lower ends of both sides of the outer surface of the fixing cylinder 7. The middle ends of both sides of the outer surface of the fixing cylinder 7 are fixed. A handle 13 is connected to the bottom of the inner cavity of the chamber 2. A fluidized bed 9 is fixedly installed at the bottom of the front surface of the chamber 2. An air inlet pipe 4 is fixedly connected to the bottom of the front surface of the chamber 2. A first quick connector is fixedly installed on the front surface of the air inlet pipe 4. A discharge pipe 3 is fixedly connected to the middle of the front surface of the chamber 2. A control valve is fixedly installed at the middle of the discharge pipe 3. A second quick connector is fixedly installed on the front surface of the discharge pipe 3. Positioning pins 24 are fixedly connected to the top of the chamber 2 around the perimeter. Positioning holes 25 are opened around the bottom of the fixed cylinder 7. The surface of the positioning pin 24 is movably connected to the surface of the positioning hole 25. A rubber pad 23 is fixedly installed at the bottom of the inner cavity of the fixed cylinder 7. The bottom of the rubber pad 23 contacts the top of the chamber 2.

[0027] In this technical solution, the guide rod 21 and guide groove 18 are used to guide the annular frame 19. The spring 20 provides elastic support between the guide rod 21 and the annular frame 19. The support shaft 8 provides support between the left side of the chamber 2 and the support frame 1. The brake caster 5 facilitates movement of the entire assembly. The fixed cover 6 supports the worm gear 10 and protects the area around the worm gear 10 and worm wheel 12.

The fluidized bed 9, with the air inlet pipe 4, can be connected to the external air supply pipeline. Since the fluidized bed 9 is made of sintered metal plate with a pore size ≤10μm, it can ensure that the airflow delivered by the air inlet pipe 4 is evenly distributed to the plastic powder inside the chamber 2 without leakage, so that the plastic powder is fluidized, which facilitates the subsequent plastic powder spraying operation. The discharge pipe 3 facilitates the connection between the personnel and the external plastic powder conveying pipeline during the plastic powder spraying operation. The positioning pin 24 and positioning hole 25 can position the fixed cylinder 7 and the chamber 2 to prevent the fixed cylinder 7 and the chamber 2 from shifting during placement. The rubber gasket 23 improves the sealing of the connection between the fixed cylinder 7 and the chamber 2.

[0028] The working principle of this utility model is as follows: The hopper 2 allows for the storage of the required powder coating during the powder coating process. The fixed cylinder 7 seals the top of the hopper 2, preventing the powder coating material from scattering to the outside. When personnel need to change the powder coating material inside the hopper 2 during powder coating, the worm gear 10 is rotated, causing the worm wheel 12 and the rotating shaft 11 to rotate along the bearing on the support frame 1. The rotation of the rotating shaft 11 causes the hopper 2 and the fixed cylinder 7 to rotate until they have rotated half a revolution, thus removing the remaining powder coating material inside the hopper 2. The powder can be poured into the fixed cylinder 7. Then, when the vibration motor 17 is started, it can drive the fixed frame 16, the annular frame 19 and the striking block 22 to vibrate. Under the action of vibration, the striking block 22 can contact the surface of the chamber 2 and strike it. Under the action of striking vibration, the plastic powder attached to the inner wall of the chamber 2 can be quickly removed, thereby achieving the effect of cleaning the plastic powder attached to the inner wall of the chamber 2. After the plastic powder is cleaned, the fixed cylinder 7 can be removed from the bottom of the chamber 2. Then, the worm gear 10 is operated to rotate, which drives the worm wheel 12, the rotating shaft 11 and the chamber 2 to rotate and reset. Then, new plastic powder can be added into the chamber 2.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
