Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 5The lithium battery anode material production feeding device of this utility model, as shown, includes a chassis 1, a controller 2 mounted on the chassis 1, a material reinforcement frame 3 fixedly connected to the chassis 1, a mixing tank 4 fixedly connected to the material reinforcement frame 3, a feed pipe 5 fixedly connected to the mixing tank 4, a first fixing frame 6 fixedly connected to the mixing tank 4, a first drive motor 7 fixedly mounted on the first fixing frame 6, a first rotating shaft 8 rotatably connected to the mixing tank 4, the first rotating shaft 8 being connected to the output shaft of the first drive motor 7, a stirrer 9 connected to the first rotating shaft 8 for mixing the raw materials, a discharge pipe 10 fixedly connected to the mixing tank 4, an electric valve 11 mounted on the discharge pipe 10, a second fixing frame 12 fixedly connected to the chassis 1, and a second fixing frame 12 fixedly mounted on the second fixing frame 12. An electric push rod 13 is connected to a first connecting rod 14 on its telescopic rod. A sliding frame 15 is connected to the first connecting rod 14. Multiple sliding wheels 16 are installed on the sliding frame 15. A third fixed frame 17 is fixedly connected to the sliding frame 15. A second drive motor 18 is fixedly installed on the third fixed frame 17. A second rotating shaft 19 is connected to the output shaft of the second drive motor 18. The second rotating shaft 19 is rotatably connected to the sliding frame 15. A rotating frame 20 is rotatably connected to the sliding frame 15. The rotating frame 20 is connected to the second rotating shaft 19. A storage box 21 is fixedly connected to the rotating frame 20. A weight sensor 22 is installed on the storage box 21. The weight sensor 22 is used to detect the weight of the raw materials. Multiple wheels 23 are installed on the chassis 1. A distance sensor 28 is installed on the second fixed frame 12.

[0018] The controller 2 is equipped with a stirring button, a stabilizing button, and a discharge button.

[0019] Multiple fourth fixing brackets 24 are fixedly connected to the chassis 1. A hydraulic cylinder 25 is fixedly installed on the fourth fixing bracket 24. The bottom end of the telescopic rod of the hydraulic cylinder 25 is connected to a second connecting rod 26. The bottom end of the second connecting rod 26 is connected to a fixing block 27.

[0020] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0021] The weight sensor is equipped with a first threshold and a second threshold, with the value of the first threshold being greater than the value of the second threshold.

[0022] After the raw materials are poured into the mixing tank through the feed pipe, the stirring button is pressed, which controls the first drive motor to work for a certain period of time and then stop. The first drive motor drives the first rotating shaft and the agitator to rotate, so that the agitator mixes the raw materials.

[0023] During the raw material mixing process, the chassis can be moved to a designated position by the wheels, bringing the chassis close to the processing equipment. Then, pressing the stabilizing button controls the hydraulic cylinder to work for a certain period of time before stopping. The hydraulic cylinder then drives the second connecting rod and the fixing block to descend. After the fixing block descends and contacts the ground, it lifts the chassis, causing the wheels to leave the ground, thereby increasing the stability during material feeding.

[0024] After the raw materials are mixed, pressing the discharge button controls the electric valve to open the discharge pipe channel, allowing the raw materials to fall into the storage bin. When the weight of the raw materials in the storage bin reaches the first threshold preset by the weight sensor, the electric valve closes the discharge pipe channel, and simultaneously controls the electric push rod to operate. The electric push rod drives the first connecting rod and the sliding frame to move. During the movement of the sliding frame, the sliding wheels improve the stability of the sliding frame. When the distance between the sliding frame and the distance sensor reaches the first threshold preset by the distance sensor, the electric push rod stops operating, and simultaneously controls the second drive motor to operate. After a certain period of time, the process stops. The second drive motor drives the second rotating shaft, rotating frame, and storage bin to rotate, causing the storage bin to tilt and slide from the storage bin into the processing equipment, thus completing the automatic feeding process. When the weight of the raw material in the storage bin is lower than the second threshold preset by the weight sensor, the electric push rod is controlled to work in reverse after a certain delay. The electric push rod drives the first connecting rod and the sliding frame to move in reverse. When the distance between the sliding frame and the distance sensor reaches the second threshold preset by the distance sensor, the electric push rod is controlled to stop working, and the second drive motor is controlled to work in reverse for a certain period of time before stopping.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
