Bearings are embedded at both ends of each fixing plate. Two conveying rollers are placed between the two fixing plates, and the front and rear ends of the two conveying rollers are respectively fixedly connected to the inner rings of two sets of bearings.

[0019] (III) Beneficial Effects

[0020] Compared with existing technologies, this quantitative packaging device for negative electrode materials has the following advantages:

[0021] 1. This utility model is equipped with a servo motor, which drives the rotating rod and spiral blade to rotate during material feeding. The spiral blade conveys and discharges the negative electrode material downwards, while simultaneously driving the scraper and stirring plate to rotate, agitating the internal material and preventing feeding obstruction. The material falls into the weighing hopper for weighing. At the start of feeding, the telescopic end of the electric push rod on the feeding hopper retracts, pulling up the sealing plate and separating it from the feeding port, thus enabling smooth feeding. After feeding, the electric push rod resets, allowing the sealing plate to close the feeding port again, preventing material slippage and affecting weighing.

[0022] 2. This utility model is equipped with a second servo motor. After the material is fed to the target weight by driving the spiral blade, the operation of the second servo motor drives the two conveying rollers and the conveyor belt to rotate inward. Since there is a gap between the guide cylinder and the conveyor belt, the material with the gap thickness will be conveyed inward during the conveying process. Thus, when the material is conveyed to the top, it is guided into the weighing hopper body for fine feeding. When the preset weight is reached, the conveying stops and the feeding stops. Therefore, the feeding accuracy can be greatly improved by coarse feeding and fine feeding, thus improving the quantitative feeding effect of the device. Attached Figure Description

The bottom end of the guide cylinder 10 extends to the top of the conveyor belt 20. The bottom end of the side mounting plate 27 is fixedly installed with the bracket 28 by the connecting rod. The bracket 28 is fixedly connected to the outer surface of the guide cylinder 10. A gap is left between the outlet end of the guide cylinder 10 and the conveyor belt 20 to better support the guide cylinder 10.

[0035] A support ring 4 is fixedly installed on the left side of the support frame 2 by bolts. A weighing hopper body 13 is fixedly installed on the top of the support ring 4. The weighing hopper 13 is a commonly used weighing method in the prior art. Multiple weighing sensors are provided between the weighing hopper body 13 and the support ring 14. The weighing sensors are electrically connected to the control board. Fixing ring 15 and fixing ring 2 14 are fixedly installed on the outer surfaces of the weighing hopper body 13 and the discharge bin 6. An opening and closing mechanism 3 is installed between each set of fixing ring 15 and fixing ring 2 14.

[0036] The opening and closing mechanism 3 includes an electric push rod 301, a hinge block 302, a connecting bend rod 303, a sealing plate 304, and a hinge frame 305. The top ends of the two electric push rods 301 are respectively hinged to the side end supports of the two fixed rings 14. The hinge frame 305 is respectively fixed to the outer surface of the two fixed rings 15. The hinge block 302 is fixed to the telescopic end of each electric push rod 301.

[0038] Working principle: During use, the negative electrode material feeding device pipe is connected to the inlet pipe 9, and the material is input into the inside of the discharge hopper 6. During the filling process, the material also enters the inside of the guide cylinder 10 and falls onto the conveyor belt 20. The weighing hopper body 13 is equipped with external bag support and sealing devices. When discharging and weighing, the electric push rod 301 on the side of the discharge hopper 6 is controlled to retract its telescopic end, pulling the sealing plate 304 to open the discharge port. At the same time, the servo motor 8 is driven to run. Within the set number of rotations of the servo motor 8, close to but not reaching the preset discharge volume, the spiral blade 23 is driven to rotate clockwise, conveying the material downward and discharging it into the inside of the weighing hopper body 13 through the discharge port, achieving the set operation. After a certain number of rotations, the electric push rod 301 on the side resets, causing the sealing plate to close the discharge port of the discharge bin 6. The weight of the lower conveyor is detected by the weighing sensor on the weighing hopper body 3. At this time, the low-speed operation of the servo motor 19 drives the conveyor belt 20 to continuously convey the material in the gap of the guide cylinder 10 to the right until it is gradually replenished into the weighing hopper body 13. After the weighing sensor detects that the preset weight has been reached, the operation of the servo motor 19 is stopped by the electronic control board, thus completing the precise discharge of the negative electrode material. At this time, the telescopic end of the electric push rod 301 on the side of the weighing hopper body 13 is retracted, opening the discharge port at the bottom, thereby discharging the weighed material into the preset packaging bag.
