Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A coating powder feeding mechanism with auxiliary stirring function includes a housing 1, a feeding component 2 at the bottom of the housing 1, and a stirring mechanism 3 inside the housing 1. The stirring mechanism 3 includes:

[0026] The stirring assembly 31 includes a rotating shaft 311 rotatably installed inside the housing 1. A rotating gear 312 is fixedly connected to the top end of the rotating shaft 311.

One end of the stirring blade 313 extends through into the interior of the rotating shaft 311 and is fixedly connected to a rotating bevel gear 314.

[0027] The drive assembly 32 is located at the top inside the housing 1;

[0028] Linkage component 33 is located at the top of the inner cavity of housing 1;

[0029] The linkage assembly 33 includes a linkage rod 331 installed on the top of the inner cavity of the housing 1. The surface of the linkage rod 331 is rotatably connected to the inside of the rotating shaft 311. Multiple sets of linkage bevel gears 332 are fixedly connected to the surface of the linkage rod 331. The surface of the linkage bevel gears 332 meshes with the surface of the rotating bevel gear 314.

[0030] The interior of the housing 1 is divided into an equipment compartment and a mixing compartment; the rotating gear 312 and the drive assembly 32 are both located in the equipment compartment.

[0031] In this embodiment, the drive assembly 32 includes a drive motor 321 installed on the top of the inner cavity of the housing 1. One end of the output shaft of the drive motor 321 is fixedly connected to a drive gear 322 via a coupling. The surface of the drive gear 322 meshes with the surface of the rotating gear 312.

[0032] The drive motor 321 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0033] The top of the linkage rod 331 is installed at the top of the inner cavity of the equipment compartment.

[0034] By starting the drive motor 321, the drive gear 322 is driven to rotate. The rotation of the drive gear 322 will drive the rotating gear 312, the rotating shaft 311, the stirring blade 313 and the rotating bevel gear 314 to rotate synchronously. When the rotating bevel gear 314 rotates, it will roll on the surface of the linkage bevel gear 332, so that the linkage bevel gear 332 and the stirring blade 313 will start to rotate on their own axis. Through the rotation and self-rotation of multiple sets of stirring blades 313, the mixing efficiency between powder coating and additives can be improved. By setting up the stirring mechanism 3, the multiple sets of stirring blades 313 will rotate on their own axis while rotating inside the box 1, thereby improving the mixing efficiency of powder coating and additives inside the box 1, thus improving the working efficiency.

[0035] In this embodiment, the feeding assembly 2 includes a guide pipe 21 and an arc plate 22 installed at the bottom of the box 1. The surface of the guide pipe 21 is rotatably connected to a feeding pipe 23. A connecting ring 24 is installed on the surface of the feeding pipe 23. A positioning assembly 25 is provided on the top of the connecting ring 24. A positioning groove 26 is provided on the bottom of the arc plate 22.

[0036] A solenoid valve is installed inside the feed tube 21 to control its opening and closing.

[0037] In this embodiment, the positioning assembly 25 includes a positioning plate 251 installed on the top of the connecting ring 24. A control block 252 is slidably connected inside the positioning plate 251. A positioning spring 253 is fixedly connected to the bottom of the control block 252. One end of the positioning spring 253 is fixedly connected to the bottom of the inner cavity of the positioning plate 251. A positioning rod 254 is fixedly connected to the top of the control block 252. One end of the positioning rod 254 is engaged with the inner surface of the positioning groove 26.

[0038] When the positioning spring 253 is not affected by external force, it will keep one end of the positioning rod 254 in a locked position with the inner surface of the positioning groove 26.

[0039] In this embodiment, a crushing box 4 is fixedly connected to the top of the box 1, a crushing device is provided inside the crushing box 4, a feeding funnel 5 is fixedly connected to the top of the crushing box 4, and a discharge pipe 6 is fixedly connected to the bottom of the crushing box 4. One end of the discharge pipe 6 extends through into the interior of the box 1.

[0040] The crushing device includes a device box installed on one side of the crushing chamber 4. A crushing motor is installed on one side of the device box. One end of the output shaft of the crushing motor is fixedly connected to a first gear and a first crushing roller through a coupling. The first crushing roller is rotatably installed inside the crushing chamber 4. A second crushing roller and a second gear are also rotatably connected inside the crushing chamber 4. The two sets of gears mesh with each other.

[0041] By activating the solenoid valve to open the feed pipe 21, the mixture of powder coating and additives is discharged and fed through the feed pipe 23. Simultaneously, by pulling down the control block 252, the positioning rod 254 can be driven to slide downward, causing the positioning spring 253 to be compressed. This allows the positioning rod 254 to fit into the positioning groove 26 at different angles. With the feed assembly 2, the opening and closing of the feed pipe 21 can be flexibly controlled by the solenoid valve, and the feeding angle of the feed pipe 23 can be flexibly controlled by the positioning assembly 25.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, powder coating and additives are first injected into the crushing chamber 4 through the feeding funnel 5. Then, the crushing motor is started, driving two sets of gears to rotate synchronously and in opposite directions. The rotation of the gears drives two sets of crushing rollers to rotate synchronously and in opposite directions. The crushing rollers crush the clumps of powder coating and additives. The crushed powder coating and additives then enter the mixing chamber inside the chamber 1 through the discharge pipe 6. At this time, the drive motor 321 is started, driving the drive gear 322 to rotate. The rotation of the drive gear 322 drives the rotating gear 312, rotating shaft 311, stirring blades 313, and rotating bevel gear 314 to rotate synchronously. The rotating bevel gear 314... During rotation, the mixture rolls on the surface of the linkage bevel gear 332, causing the linkage bevel gear 332 and the stirring blade 313 to rotate on their own axis. The rotation and self-rotation of multiple sets of stirring blades 313 can improve the mixing efficiency between powder coating and additives. Finally, by activating the solenoid valve to open the feed pipe 21, the mixture of powder coating and additives is discharged through the feed pipe 23. Simultaneously, by pulling down the control block 252, the positioning rod 254 can slide downward, compressing the positioning spring 253. This allows the positioning rod 254 to adapt to the positioning groove 26 at different angles, flexibly adjusting the feeding position of the feed pipe 23.
