The produced slurry is stored in storage tanks for later use. When the slurry is needed, a pump is used to transport the slurry from the storage tank to a transfer tank, and then from the transfer tank to the electrode sheets on the production line. Existing slurry feeding systems (such as the feeding system, slurry coating device, and battery production system disclosed in application number 202210692347.1) can only feed slurry to the electrode sheets on one production line. In large-scale enterprises, multiple such production lines need to be set up to meet production needs, which makes the feeding process relatively decentralized and inconvenient for centralized management. Utility Model Content

This system solves the technical problem that existing slurry feeding systems can only feed materials to the electrode sheets on one production line.

Each feeding tank corresponds to a production line, each adapter corresponds to a feeding tank, and each adapter rotation drive is connected to an adapter to drive the adapter to rotate, so that the adapter connects the outlet end of the drive pump and the inlet end of the feeding tank, or blocks the outlet end of the drive pump and the inlet end of the feeding tank.

[0005] Furthermore, the adapter is a columnar structure, and the arc-shaped wall of the adapter is in sealed sliding contact with the outlet end of the drive pump and the inlet end of the feeding tank. A channel is opened on the adapter, and during the rotation of the adapter, the two ends of the channel are respectively connected to the outlet end of the drive pump and the inlet end of the feeding tank.

[0006] Furthermore, the feeding mechanism also includes multiple adapter shells, each adapter shell having a columnar adapter cavity. The adapter shell has an inlet and an outlet communicating with the adapter cavity. Each inlet is also connected to the outlet end of the drive pump. Each outlet is connected to the inlet end of each feeding tank. Each adapter is correspondingly and rotatably disposed in each adapter cavity.

[0008] Furthermore, the feeding mechanism also includes multiple weighing sensors, each weighing sensor being connected to each of the feeding tanks in a one-to-one correspondence, to weigh the slurry in the feeding tanks.

[0009] Furthermore, the slurry feeding system also includes multiple feeding mechanisms, each of which is correspondingly located directly below each feeding tank and is used to receive the slurry in the feeding tank to quantitatively deliver the slurry in the feeding tank to each coating area on the electrode.

[0010] Furthermore, the feeding mechanism includes a feeding shell, a feeding platform, and a feeding rotation drive. The feeding shell has a columnar structure and a feeding cavity with an open top.

When the slurry is needed, by controlling each connecting rotating drive component, each connecting rotating drive component can drive the corresponding connecting component to rotate. According to the actual processing requirements of the production line, the connecting component can connect the outlet end of the drive pump and the inlet end of the feeding tank, or the connecting component can block the outlet end of the drive pump and the inlet end of the feeding tank. When the connecting component connects the outlet end of the drive pump and the inlet end of the feeding tank, the drive pump can pump the slurry in the storage tank to the feeding tank, and then feed it to the electrode on the production line through the feeding tank. When the connecting component blocks the outlet end of the drive pump and the inlet end of the feeding tank, the drive pump cannot pump the slurry in the storage tank to the feeding tank, and at this time, it is not possible to feed it to the electrode on the production line through the feeding tank. The slurry feeding system provided by this utility model can drive a pump to feed materials into multiple feeding tanks simultaneously according to actual processing needs, making this slurry feeding system suitable for use by large-scale enterprises and enabling centralized management of the feeding process.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] This utility model provides a slurry feeding system, the structure of which is as follows: Figure 1 and Figure 2 As shown, the device includes a storage mechanism 100 and a feeding mechanism 200. The storage mechanism 100 includes a storage tank 110 and a drive pump 120, with the inlet end of the drive pump 120 connected to the storage tank 110. The feeding mechanism 200 includes multiple feeding tanks 210, multiple adapters 220, and multiple adapter rotation drive components 230. Each feeding tank 210 corresponds to a specific production line, each adapter 220 corresponds to a specific feeding tank 210, and each adapter rotation drive component 230 is connected to a specific adapter 220 to drive the adapter 220 to rotate, thereby connecting the adapter 220 to the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, or blocking the outlet end of the drive pump 120 and the inlet end of the feeding tank 210.

[0018] During use, the produced slurry is stored in the storage tank 110 for later use. When the slurry is needed, by operating each of the adapter rotation drive components 230, each adapter rotation drive component 230 can drive the corresponding adapter component 220 to rotate. Depending on the actual processing requirements of the production line, the adapter component 220 can connect the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, or it can block the outlet end of the drive pump 120 and the inlet end of the feeding tank 210. When the adapter component 220 connects the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, the drive pump 120 can... The slurry in the storage tank 110 is pumped into the feeding tank 210, and then fed onto the electrode sheets on the production line through the feeding tank 210. When the adapter 220 blocks the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, the drive pump 120 cannot pump the slurry in the storage tank 110 into the feeding tank 210. At this time, it is not possible to feed the electrode sheets on the production line through the feeding tank 210. Since the drive pump 120 can feed into multiple feeding tanks 210 simultaneously according to actual processing needs, this slurry feeding system is suitable for use by large-scale enterprises and allows for centralized management of the feeding process.

[0019] In a preferred embodiment, the storage mechanism 100 further includes a stirring assembly, which includes a stirring paddle and a stirring rotation drive. The stirring paddle is disposed inside the storage tank 110. The output end of the stirring rotation drive is connected to the upper end of the main shaft of the stirring paddle, and is used to drive the main shaft of the stirring paddle to rotate, so that the stirring paddle stirs the slurry in the storage tank 110. When the stirring rotation drive is activated, it drives the main shaft of the stirring paddle to rotate. The stirring paddle can stir the slurry in the storage tank 110, which can mix the slurry on the one hand, and prevent the sedimentation of particles in the slurry on the other hand.

[0020] As a preferred embodiment, please refer to Figure 2 and Figure 3 Each of the adapters 220 is positioned directly above each of the feeding tanks 210, thereby allowing the slurry to enter the feeding tank 210 from the top.

[0021] As a preferred embodiment, please refer to Figure 2 and Figure 3The adapter 220 is a columnar structure. The arc-shaped wall of the adapter 220 is in sealed sliding contact with the outlet end of the drive pump 120 and the inlet end of the feeding tank 210. A channel 221 is provided on the adapter 220. During rotation of the adapter 220, both ends of the channel 221 are connected to the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, respectively. Because the adapter 220 is a columnar structure, it can also... The channel 221 is sealed and slidably abuts against the outlet end of the drive pump 120 and the inlet end of the feed tank 210, thereby blocking the outlet end of the drive pump 120 and the inlet end of the feed tank 210. A passage can only be formed when both ends of the channel 221 are connected to the outlet end of the drive pump 120 and the inlet end of the feed tank 210, respectively. The slurry can enter the feed tank 210 along the passage, avoiding the need for manual operation of valves to open and close the liquid path when using traditional valves.

[0022] As a preferred embodiment, please refer to Figure 3 Both ends of the channel 221 are located on the arc-shaped wall of the connector. During the rotation of the adapter 220, both ends of the channel 221 can be connected to the outlet end of the drive pump 120 and the inlet end of the feeding tank 210, respectively.

[0023] As a preferred embodiment, please refer to Figure 2 and Figure 3 The feeding mechanism 200 also includes multiple adapter shells 240. Each adapter shell 240 has a columnar adapter cavity 241. The adapter shell 240 has an inlet 242 and an outlet 243 that communicate with the adapter cavity 241. Each inlet 242 is also connected to the outlet end of the drive pump 120. Each outlet 243 is connected to the inlet end of each feeding tank 210. Each adapter 220 is correspondingly and rotatably disposed in each adapter cavity 241. During the rotation of the adapter 220, the two ends of the channel 221 are connected to the inlet 242 and the outlet 243 respectively. The adapter shell 240 can play a supporting and sealing role, improving the sealing effect of the adapter 220.

[0024] As a preferred embodiment, please refer to Figure 2 and Figure 3 The feed inlet 242 and the discharge outlet 243 are both located on the arc-shaped wall of the transition cavity 241, so that during the rotation of the adapter 220 in the transition cavity 241, the two ends of the channel 221 can be connected to the feed inlet 242 and the discharge outlet 243 respectively.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3 The fixed end of the adapter rotation drive 230 is fixedly connected to the adapter shell 240, the output end of the adapter rotation drive 230 is coaxially fixedly connected to the adapter 220, and the adapter shell 240 can support the adapter rotation drive 230.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3 The feeding mechanism 200 also includes a feeding pipeline 250. The inlet end of the feeding pipeline 250 is connected to the outlet end of the drive pump 120. Each outlet end of the feeding pipeline 250 is connected to each of the feed inlets 242. When the drive pump 120 is started, it can pump the slurry in the storage tank 110 into the feeding pipeline 250. When the two ends of the channel 221 are connected to the feed inlets 242 and the outlets 243 respectively, the slurry in the feeding pipeline 250 can enter the feeding tank 210 along the channel 221. The feeding pipeline 250 can realize the guiding of the slurry.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 The feeding pipeline 250 includes a main feeding pipe 251 and multiple branch feeding pipes 252. One end of the main feeding pipe 251 is connected to the outlet end of the drive pump 120. One end of each branch feeding pipe 252 is connected to the main feeding pipe 251. The other end of each branch feeding pipe 252 is connected to each feed inlet 242. When the drive pump 120 is started, it can pump the slurry in the storage tank 110 into the main feeding pipe 251 and each branch feeding pipe 252. When the two ends of the channel 221 are connected to the feed inlet 242 and the outlet 243 respectively, the slurry in the branch feeding pipe 252 can enter the feeding tank 210 along the channel 221. The main feeding pipe 251 and each branch feeding pipe 252 can guide the slurry.

[0028] As a preferred embodiment, please refer to Figure 2The feeding mechanism 200 also includes multiple weighing sensors 260, each weighing sensor 260 being connected to each feeding tank 210 to weigh the slurry in the feeding tank 210. When the slurry in the feeding tank 210 reaches a preset weight, the adapter rotation drive 230 is activated, driving the corresponding adapter 220 to rotate. This allows the adapter 220 to block the inlet 242 and the outlet 243, preventing the slurry in the feed pipe 252 from entering the feeding tank 210 along the channel 221. This avoids the need for manual operation of valves to control the flow of liquid when using traditional valves.

[0029] As a preferred embodiment, please refer to Figure 2 The feeding mechanism 200 also includes a plurality of solenoid valves 270, each of which is correspondingly disposed at the outlet end of each feeding tank 210 to control the opening and closing of the outlet end of the feeding tank 210.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 4 The slurry feeding system further includes multiple feeding mechanisms 300, each of which is correspondingly arranged directly below each feeding tank 210 and is used to receive the slurry in the feeding tank 210 to quantitatively deliver the slurry in the feeding tank 210 to each coating area on the electrode. Since multiple coating areas are arranged linearly on each electrode, the feeding mechanism 300 can ensure that the amount of slurry on each coating area is equal, thus ensuring feeding accuracy.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4The feeding mechanism 300 includes a feeding shell 310, a feeding platform 320, and a feeding rotation drive 330. The feeding shell 310 has a columnar structure and a feeding cavity 311 with an open top. The bottom of the feeding shell 310 has a feeding port 312 communicating with the feeding cavity 311. The feeding port 312 is offset from the outlet end of the feeding tank 210. The feeding platform 320 is a columnar structure and is rotatably and sealed within the feeding cavity 311. The feeding platform 320 has multiple receiving slots 321 with open tops and bottoms, and each receiving slot 321 is arranged in a ring array. The output end of the feeding rotation drive 330 is connected to the feeding platform 320. The feeding platform 320 is then driven to rotate so that each of the receiving grooves 321 is sequentially connected to the outlet end of the feeding tank 210 or the discharge port 312. The feeding rotation drive 330 is activated, and the feeding rotation drive 330 drives the feeding platform 320 to rotate. When the receiving groove 321 is connected to the outlet end of the feeding tank 210, the slurry in the feeding tank 210 enters the receiving groove 321. When the receiving groove 321 is connected to the discharge port 312, the slurry in the feeding tank 210 is discharged along the discharge port 312 and reaches a coating area of ​​the electrode. The continuous rotation of the feeding platform 320 can realize the feeding of material to each coating area of ​​the electrode.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 4 The fixed end of the feeding rotation drive 330 is fixedly connected to the feeding shell 310, and the output end of the feeding rotation drive 330 is coaxially fixedly connected to the feeding platform 320. The feeding shell 310 can support the feeding rotation drive 330.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 4 The feeding mechanism 300 further includes a boss 340 and a scraper 350. The boss 340 is a columnar structure and is coaxially fixed to the top of the feeding platform 320. The arc-shaped wall of the boss 340 and the cavity wall of the feeding chamber 311 form a feeding interval with a column-ring structure. Each of the receiving grooves 321 is located in the feeding interval. The scraper 350 is disposed in the feeding interval and is fixedly connected to the feeding shell 310. The bottom surface of the scraper 350 is slidably connected to the top surface of the feeding platform 320. Since the slurry has a certain viscosity, during the rotation of the feeding platform 320, the scraper 350 can scrape the slurry in the receiving groove 321 to make the weight of the slurry in each receiving groove 321 the same, thereby improving the accuracy of quantitative feeding.

[0034] As a preferred embodiment, please refer to Figure 2 and Figure 4 The feeding mechanism 300 also includes a feeding guide component 360, the inlet end of which is connected to the feeding port 312 and is used to guide the slurry onto the electrode to avoid slurry splashing.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 4 The material guiding assembly 360 includes a material guiding tube 361 and a telescopic drive component 362. The material guiding tube 361 has a thin tube section and a tapered tube section connected sequentially from bottom to top. The upper end of the material guiding tube 361 is connected to the discharge port 312. The output end of the telescopic drive component 362 is fixedly connected to the material guiding tube 361 and is used to drive the material guiding tube 361 to move up and down to adjust the distance between the bottom of the material guiding tube 361 and the electrode. When the receiving groove 321 is connected to the discharge port 312, When the telescopic drive 362 is activated, it can drive the guide tube 361 to move downward, thereby reducing the distance between the bottom of the guide tube 361 and the electrode sheet and preventing slurry splashing. After the feeding is completed, the telescopic drive 362 is activated again, and it can drive the guide tube 361 to move upward, thereby increasing the distance between the bottom of the guide tube 361 and the electrode sheet and preventing the lower end of the guide tube 361 from interfering with the movement of the electrode sheet on the production line.

[0036] In a preferred embodiment, the slurry feeding system further includes a frame, with the storage tank 110 fixedly connected to the frame, the adapter shell 240 fixedly connected to the frame, the weighing sensor 260 fixedly connected to the frame, and the discharge shell 310 fixedly connected to the frame. The frame can support the storage tank 110, the adapter shell 240, the weighing sensor 260, and the discharge shell 310.

[0037] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below: During use, the produced slurry is stored in the storage tank 110 for later use. When it is necessary to feed the slurry to one or more electrode sheets on the production line, the drive pump 120 is started. The drive pump 120 can draw the slurry in the storage tank 110 into the main feed pipe 251 and each of the branch feed pipes 252. Then, the corresponding transfer drive 230 on the production line is started. The transfer drive 230 drives the corresponding transfer component 220 to rotate until both ends of the channel 221 are connected to the inlet 242 and the outlet 243, respectively. When the feed inlet 242 and the discharge outlet 243 are connected, the slurry in the feed pipe 252 can enter the feed tank 210 along the channel 221. When the slurry in the feed tank 210 reaches a preset weight, the adapter rotation drive 230 is activated, driving the corresponding adapter 220 to rotate. This allows the adapter 220 to block the feed inlet 242 and the discharge outlet 243, preventing the slurry in the feed pipe 252 from entering the feed tank 210 along the channel 221. The solenoid valve 270 then opens the discharge outlet of the feed tank 210. At the discharge port 312, the feeding rotation drive 330 is activated, driving the feeding platform 320 to rotate. When the receiving groove 321 is connected to the outlet end of the feeding tank 210, the slurry in the feeding tank 210 enters the receiving groove 321. When the receiving groove 321 is connected to the discharge port 312, the telescopic drive 362 is activated, driving the guide tube 361 to move downwards. This reduces the distance between the bottom of the guide tube 361 and the electrode, allowing the slurry to move downwards along the guide tube 361 and reach a coating area on the electrode, avoiding... To prevent slurry splashing, after the feeding is completed, the telescopic drive 362 is activated, which drives the guide tube 361 to move upward, increasing the distance between the bottom of the guide tube 361 and the electrode sheet. This prevents the lower end of the guide tube 361 from interfering with the movement of the electrode sheet on the production line. The continuous rotation of the unloading platform 320 enables the feeding of material to various coating areas of the electrode sheet. Since the drive pump 120 can simultaneously feed material into multiple feeding tanks 210 according to actual processing needs, this slurry feeding system is suitable for use by large-scale enterprises and allows for centralized management of the feeding process.

[0038] The slurry feeding system provided by this utility model has the following beneficial effects: (1) During the rotation of the adapter 220, it can be sealed and slidably abutted against the outlet end of the drive pump 120 and the inlet end of the feed tank 210, thereby blocking the outlet end of the drive pump 120 and the inlet end of the feed tank 210. Only when the two ends of the channel 221 are connected to the outlet end of the drive pump 120 and the inlet end of the feed tank 210 respectively can a passage be formed, and the slurry can enter the feed tank 210 along the passage, avoiding the need for manual operation of the valve to realize the opening and closing of the liquid path when a traditional valve is set. (2) Since multiple coating areas are arranged linearly on each electrode, the feeding mechanism 300 can make the amount of slurry on each coating area equal, ensuring the feeding accuracy. The feeding rotation drive 330 is started, and the feeding rotation drive 330 drives the feeding platform 320 to rotate. When the receiving groove 321 is connected to the outlet end of the feeding tank 210, the slurry in the feeding tank 210 enters the receiving groove 321. When the receiving groove 321 is connected to the feeding port 312, the slurry in the feeding tank 210 is discharged along the feeding port 312 and reaches a coating area of ​​the electrode. The continuous rotation of the feeding platform 320 can realize the feeding of materials to each coating area of ​​the electrode. (3) Since the drive pump 120 can feed materials into multiple feeding tanks 210 at the same time according to actual processing needs, this slurry feeding system is suitable for use by large-scale enterprises and can centrally manage the feeding process.
