[0021] The above-mentioned material feeding device for producing lithium batteries has a novel structure. The design and coordination of the first discharge port 240, the first discharge pipe 310, the first solenoid valve 311, the second discharge port 250, the second discharge pipe 320, the second solenoid valve 321, the third discharge port 260, the third discharge pipe 330, and the third solenoid valve 331 can be opened accordingly according to the actual feeding quantity requirements, which can effectively prevent excessive feeding; and, the inside of the feeding pipe 200 is provided with a first spiral stirring rod 410 and a second spiral stirring rod 420, which can be adjusted according to the corresponding rotation speed according to the needs to control the feeding speed, which can effectively improve the accuracy of feeding.

[0022] Furthermore, the bottom of the feeding trough 270 is an arc-shaped structure, and the outer side of the second spiral stirring rod 420 is against the inner wall of the feeding trough 270 for rotation; this structural design can facilitate the second spiral stirring rod 420 to effectively scrape and push the material, thereby facilitating the discharge of the material.

[0023] Furthermore, the bottom surface of the feeding pipe 200 is tilted downwardly on one side close to the feeding trough 270, and the lower tilted side is connected to the feeding trough 270; this structural design can facilitate the material inside the feeding pipe 200 to smoothly enter the feeding trough 270, thereby facilitating the flow and pushing of the material.

[0024] Furthermore, a limit plate 280 is fixedly provided on the inner wall of one end of the feeding pipe 200 away from the feeding port, and the limit plate 280 is located above the feeding trough 270 and corresponds to the position of the third discharge port 260. One end of the limit plate 280 abuts against the end cover 210, and the other end extends to the side of the second discharge port 250 close to the third discharge port 260. The design of the limit plate 280 allows the material to enter the third discharge port 260 only through the feeding trough 270, which can effectively limit the moving speed of the material and facilitate the control of the delivery speed.

[0025] Furthermore, the diameter of the first spiral stirring rod 410 is greater than the diameter of the second spiral stirring rod 420, so as to facilitate corresponding startup according to the feeding amount and facilitate adjustment and control of the material pushing speed.

[0026] Furthermore, a vibration motor 290 is fixedly installed on the outer wall of the feeding hopper 230 , which can facilitate the material in the feeding hopper 230 to enter the feeding pipe 200 .

[0027] Furthermore, the top surface of the frame 100 is tilted, the bottom of the feeding pipe 200 is installed on the top surface of the frame 100, and the end of the feeding pipe 200 close to the feeding hopper 230 is at a lower tilted side; so that one end of the discharge port of the feeding pipe is tilted upward to prevent the material from being easily discharged, and the material needs to be delivered by the first spiral stirring rod 410 and the second spiral stirring rod 420.

[0028] More specifically, when the material is released, corresponding adjustments can be made according to the demand for the release amount. If the release amount is small, the third solenoid valve 331 can be opened, the second motor 440 can be started, and the material can be driven to be released through the second spiral stirring rod 420; due to the design of the limit plate 280, the material can only enter the third discharge port 260 through the feeding trough 270, which can effectively limit the movement speed of the material and facilitate the control of the release speed; if the release amount is large, the first motor 430 and the second motor 440 can be turned on simultaneously, so that the first spiral stirring rod 410 and the second spiral stirring rod 420 are in a rotating feeding state, and then the first solenoid valve 311 is opened and closed after the preset time is reached, and then the second solenoid valve 321 is opened and closed after the preset time is reached, and finally the third solenoid valve 331 is opened, and the first motor 410 is stopped, and only the second motor is used to push the material, and a small amount of release is performed, so as to control the release speed and release amount and improve the accuracy of the release amount.

[0029] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
