A rotating shaft 214 is fixedly connected to the lower surface of the driving gear 312. A spiral groove is formed on the upper surface of the cross-shaped blocking plate 212. A shifting rod is arranged on the outer surface of the rotating shaft 214, and the outer surface of the shifting rod is slidably connected to the inner surface of the spiral groove. A caulking block 216 is fixedly connected to the outer surface of the material guiding plate 206. One side of the caulking block 216 is of an arc structure. Among them, through the mutual cooperation of the cross-shaped blocking plate 212 and the weighing plate 205, the weighing plate 205 weighs the amount of raw materials required for the lithium battery, and then the shifting rod is used to adjust the cross-shaped blocking plate 212, so that the weighed raw materials can be quickly discharged.

[0046] Working principle: By using the feeding box 102, the blocking plate 103, the collection box 112, the pump body 114, the storage box 115, the placement groove 117 and the material holding frame 119, when the lithium battery needs to be loaded, the electric push rod 118 drives the whole blocking plate 103 to rise, so that the lithium battery enters the feeding box 102 for loading. Further, when the pump body 114 injects materials into the feeding box 102, due to the distance between the injection pipe 209 and the lithium battery, it is easy for the raw materials to fly in the feeding box 102. Then, the air inlet box 105 and the first air extraction box are used to collect the raw materials flying in the lithium battery, preventing a large amount of raw materials from adhering to the inner surface of the equipment, and thus improving the feeding capacity of the equipment to a certain extent.

[0047] By using the control pipe 202, the second solenoid valve 203, the inclined chute 204, the weighing plate 205, the material guiding plate 206, the limiting disk 211, the cross-shaped blocking plate 212, the arc-shaped spring 218, the sliding block 219, the rotating groove 220 and the limiting rod 221, the material guiding plate 206 collects the stirred raw materials, and the weighing plate 205 measures the weight of the raw materials. At the same time, the rotating shaft 214 drives the shifting rod on its outer surface to rotate, so that the shifting rod slides in the spiral groove, and the shifting rod pushes the cross-shaped blocking plate 212 to rotate in the rotating groove 220. Then, through the deformation of the arc-shaped spring 218, the cross-shaped blocking plate 212 opens the slot on the upper surface of the guiding plate 213, so that the raw materials can be quickly discharged.

[0048] Utilize the drive motor 304, L-shaped tube 305, blanking chute 306, material separation plate 307, stirring soft rod 308, stirring shaft 309, connecting shaft 310, secondary driving gear 311, driving gear 312, fixed soft rod 313, cross partition plate 314, support ring 315, Y-shaped plate 316 and insertion slot 317, so that the drive motor 304 drives the driving gear 312 to rotate, and then the driving gear 312 drives the secondary driving gear 311 to rotate, thereby enabling the secondary driving gear 311 to drive the stirring shaft 309 to rotate through the connecting shaft 310, and making the stirring soft rod 308 cooperate with the fixed soft rod 313 to break up the lumps in the raw materials, making the raw materials more convenient for weighing and feeding.

[0049] Embodiment 2:

Among them, when the cross-shaped blocking plate 212 rotates, the limiting disk 211 prevents it from moving to the outer surface of the rotating groove 220, and then the raw materials are intermittently discharged through the cross-shaped blocking plate 212.

[0052] Furthermore, the drive box 302 is fixedly connected with a drive motor 304 through a connecting plate 108. A feed hopper 303 is fixedly connected to one side of the connecting plate 108 close to the drive motor 304. A Y-shaped plate 316 is fixedly connected to the lower surface of the feed hopper 303. A driving gear 312 is rotatably connected in the drive box 302. Multiple secondary driving gears 311 are symmetrically distributed at equal intervals on the outer surface of the driving gear 312. The secondary driving gears 311 are fixedly connected with a stirring shaft 309 through a connecting shaft 310. Among them, through the mutual cooperation of the driving gear 312 and the secondary driving gears 311, the stirring shaft 309 fully breaks up the agglomerated raw materials. Further, multiple feed hoppers 303 are used to inject different raw materials respectively, so that the device can feed different powders at the same time.

[0053] Furthermore, one end of the Y-shaped plate 316 penetrates through the lower surface of the drive box 302. Fixed flexible rods 313 are symmetrically distributed at equal intervals on the outer edge of the cross-shaped partition plate 314. An L-shaped pipe 305 is fixedly connected to the outer surface of the stirring pipe 301. One side of the L-shaped pipe 305 is fixedly connected to one side of the collection box 112. Among them, when the cross-shaped partition plate 314 stirs the raw materials, the device can stir different raw materials at the same time, thereby improving the feeding effect of the device to a certain extent.

[0054] Furthermore, the lower surface of the Y-shaped plate 316 is fixedly connected to the upper surface of the support ring 315. An insertion groove 317 is formed in the support ring 315. The inner diameter of the insertion groove 317 is adapted to the outer diameter of the Y-shaped plate 316. Multiple discharge grooves 306 are symmetrically distributed at equal intervals in the partition plate 307. The lower surface of the support ring 315 is fixedly connected to the inner surface of the drive box 302. Among them, the discharged mixed raw materials are discharged through the discharge grooves 306. Further, the second solenoid valve 203 on the lower surface of the partition plate 307 is used to quantitatively control the discharge of the raw materials.

[0055] Working principle: During operation, the base 101 stably supports the entire device. The injection box 102 serves as a temporary storage and metering container for powders. The connecting plate 108 on the support plate 104 is used to fix other functional units. The air inlet box 105 is connected to the collection system and is used to extract flying powders. The powders enter the protection pipe 201 from the injection box 102, fall into the weighing groove 217 on the weighing plate 205 through the guiding plate 213 and the connecting pipe 210. The weighing plate 205 is internally provided with sensors to monitor the weight of the powders in real time;

[0056] Secondly, when the preset value is reached, the first solenoid valve 208 closes to stop the feeding. The inclined chute 204 on the material guide plate 206 ensures the smooth flow of the powder. The powder is evenly mixed and quantitatively discharged through the mixing pipe 301, the drive box 302 and the mixing components. The drive motor 304 drives the driving gear 312 to rotate, thereby driving the driven gear 311 and the mixing shaft 309 to rotate. The mixing flexible rod 308 and the fixed flexible rod 313 are distributed on the mixing shaft 309 to effectively break up the lumps in the powder.

[0057] Thirdly, the cross partition plate 314 divides the mixing pipe 301 into multiple areas, allowing different powders to be processed simultaneously. The discharge chute 306 on the partition plate 307 controls the discharge of the mixed powder. The collection box 112 is located below the mixing and discharging unit 300 and is used to collect the flying powder and the excessive powder. The pump body 114 is connected to the air inlet box 105 and the confluence pipe 111 through the first suction pipe 107 and the second suction pipe 113 to extract the flying powder to the storage box 115. The fine filter plate in the storage box 115 ensures the clean discharge of the gas. The material receiving frame 119 and the partition plate in the collection box 112 allow different powders to be separately collected and discharged through the inclined discharge pipe 109 respectively.

[0058] Finally, the blocking plate 103 driven by the electric push rod 118 seals in the feeding box 102 to prevent the powder from flying out. The L-shaped pipe 305 and the second solenoid valve 203 further control the powder flow rate on the material guide plate 206 to reduce flying. The coordinated work of the cross blocking plate 212 and the weighing plate 205 ensures the rapid and accurate discharge of the powder after weighing.
