The gear chamber is fixedly installed on the upper surface of the shell, and the motor chamber is fixedly connected to the top of the gear chamber. A driving gear fixedly connected to a driving motor is arranged inside the gear chamber. The bottom of the driving gear is fixedly connected to a main stirring shaft extending to the inside of the shell. A groove is provided on the lower surface of the main stirring shaft. The driving motor drives the driving gear to rotate clockwise, and the driving gear drives the main stirring shaft and the stirring blade fixedly connected to the outside of the main stirring shaft to rotate clockwise, so as to stir the lithium battery slurry clockwise. At the same time, when the driving gear rotates, it will also drive the driven gears on both sides to rotate counterclockwise, and the driven gear drives the auxiliary stirring shaft to rotate counterclockwise, and the auxiliary stirring shaft drives the stirring blade fixedly connected to the outside of the auxiliary stirring shaft to rotate counterclockwise, so as to stir the lithium battery slurry counterclockwise, so as to finally achieve the effect of simultaneously stirring the lithium battery slurry clockwise and counterclockwise, so that the components of the lithium battery slurry can be effectively mixed, and the stirring effect is improved.

[0004] In the above scheme, when the lithium battery slurry is stirred, the powdered raw materials and the liquid raw materials are put into the shell together for mixing and stirring, resulting in large differences in the dryness and wetness of different areas of the mixture formed in the shell. The mixture is prone to agglomeration during mixing, which makes the raw materials in the shell mix slowly, thereby reducing the efficiency of the entire lithium battery slurry preparation; for this reason, the present invention provides a lithium battery slurry preparation device.

[0007] First, the liquid raw material and the solid powder raw material are mixed separately, and then the solid powder is added to the liquid raw material intermittently and in small amounts by repeatedly pushing and pulling the material block to avoid agglomeration during mixing.

[0008] Preferably, the blanking mechanism further comprises two sets of guide sleeves, the guide sleeves on both sides are symmetrically arranged on both sides of the end of the blanking block, the guide sleeves are plugged into the guide pillars, and one end of the guide pillars is fixedly connected to the outer ring of the base;

[0009] Specifically, when the blanking block is pushed and pulled, the blanking block will drive the guide sleeve to slide back and forth along the guide pillar, and the cooperation between the guide pillar and the guide sleeve plays a guiding role in the movement of the blanking block.

[0010] Preferably, the material discharge mechanism further comprises a first gear, the first gear is fixedly sleeved on the base, a second gear meshing with the first gear, the second gear is rotatably mounted on one side of the base, a bent rod, one end of the bent rod is connected to the end of the material discharge block, an annular groove is provided on the upper end surface of the main mixing barrel, the other end of the bent rod is located in the annular groove, the annular groove is composed of four groups of arc grooves and four groups of V-shaped grooves, and the axis of the arc groove is located on the central axis of the base;

[0011] Since four groups of V-shaped grooves are provided and adjacent V-shaped grooves are connected by arc grooves, not only can the solid powder raw materials be intermittently added into the main mixing barrel, but also the solid powder raw materials can be put into different areas in the main mixing barrel, so that the solid powder raw materials can be put into the main mixing barrel more evenly, thereby improving the mixing efficiency of the solid powder raw materials and the liquid raw materials.

[0012] Preferably, the blanking block includes a driven block, the driven block is movably inserted into a rectangular slot, two sets of U-shaped clamps movably installed at one end of the driven block, a receiving rod fixedly connected to one end of the U-shaped clamp, a driving block, both sets of receiving rods are inserted into the driving block, two sets of guide sleeves are respectively fixed on both sides of the driving block, a movable plate movably installed in the driving block, one end of a bent rod is fixedly connected to the movable plate, two sets of pressure-bearing blocks, the two sets of pressure-bearing blocks are respectively fixed on both sides of the movable plate, a spring arranged above the pressure-bearing block, a first rectangular groove and a second rectangular groove are formed in the driving block, the first rectangular groove and the second rectangular groove communicate with each other, both sets of receiving rods are located in the second rectangular groove, the movable plate is inserted into the first rectangular groove, a number of convex blocks for pushing the bent rod are arranged in each of the four arc grooves, two inclined grooves are symmetrically formed on the movable plate, a pin shaft is arranged at one end of the receiving rod, and the pin shaft is located in the inclined groove;

[0013] Due to the fact that there are multiple convex blocks in the arc groove, after the other end of the bent rod passes through multiple convex blocks, the two sets of U-shaped clamps will be repeatedly impacted.

[0015] The cooperation between the sliding rod and the through hole and the cooperation between the guide rail and the guide groove both play a guiding role in the movement of the U-shaped clamp.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. First, the liquid raw material and the solid powder raw material are separately mixed evenly, and then by repeatedly pushing and pulling the blanking block, the solid powder is intermittently and in small amounts added to the liquid raw material, avoiding the agglomeration phenomenon during mixing.

[0018] 2.

Since there are four sets of V-shaped grooves and the adjacent V-shaped grooves are connected by arc grooves, not only can the solid powder raw material be intermittently added into the main mixing barrel, but also the solid powder raw material can be put into different areas of the main mixing barrel, making the solid powder raw material more evenly put into the main mixing barrel and improving the mixing efficiency of the solid powder raw material and the liquid raw material.

[0019] 3. When the other end of the bent rod slides from the V-shaped groove into the arc-shaped groove, the other end of the bent rod will be squeezed by a set of bumps, causing the bent rod to be pushed upward. At the same time, the bent rod drives the movable plate and the two sets of pressure-bearing blocks to move upward together. The pressure-bearing blocks will compress the spring.

Detailed implementation mode

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0030] Example 1: As Figure 1 shown in Figure 2 a lithium battery slurry preparation device according to an embodiment of the present invention includes a main mixing barrel 1. A blanking mechanism 2 is arranged at the upper end of the main mixing barrel 1. A secondary mixing barrel 3 is arranged on the blanking mechanism 2. A driving shaft 4 is rotatably installed in the secondary mixing barrel 3. A dust cover 5 is fixedly connected to the lower end of the secondary mixing barrel 3. The dust cover 5 is fixedly installed at the upper end of the main mixing barrel 1. A secondary stirring shaft 6 and a main stirring shaft 7 are fixedly sleeved on the driving shaft 4. The secondary stirring shaft 6 and the main stirring shaft 7 are respectively located in the secondary mixing barrel 3 and the main mixing barrel 1. The blanking mechanism 2 includes a base 201. The base 201 is fixedly installed at the middle part of the upper end of the main mixing barrel 1. The lower end of the secondary mixing barrel 3 is rotatably connected to the base 201, and the dust cover 5 is sleeved on the base 201. The driving shaft 4 passes through the base 201 and extends into the main mixing barrel 1. A rectangular slot 202 is opened on one side of the base 201. A blanking block 203 is movably inserted into the rectangular slot 202. A material receiving groove 31 is arranged on the blanking block 203. A blanking port 21 is opened on the upper side in the rectangular slot 202. Four feeding ports 501 are opened on the upper end surface of the main mixing barrel 1.

[0031] Specifically, in the initial state, the material holding trough 31 is located outside the rectangular slot 202, and the material discharge block 203 is coated with a rubber layer. When it is necessary to prepare lithium battery slurry, the liquid raw material for making lithium battery slurry is added to the main mixing barrel 1, and then the solid powder raw material is added to the secondary mixing barrel 3. The driving shaft 4 is driven by the motor to rotate, and the driving shaft 4 drives the secondary stirring shaft 6 to rotate together with the main stirring shaft 7, so that the liquid raw material in the main mixing barrel 1 and the solid powder raw material in the secondary mixing barrel 3 are separated and independently mixed. After the liquid raw material and the solid powder raw material are mixed, the driving shaft 4 is kept rotating at a constant speed, so that the ends of a group of electric push rods are connected to the ends of the material discharge block 203, and then the material discharge block 203 is pushed by the electric push rod to move along the rectangular slot 202 toward the inside of the secondary mixing barrel 3 until the material holding trough 31 on the material discharge block 203 is located at the material discharge port 2 1, at this time, the solid powder raw material in the secondary mixing barrel 3 will flow into the material trough 31 through the discharge port 21 to achieve material collection, and then the electric push rod will pull the discharge block 203 to move back until the material trough 31 returns to the initial position. Under the action of gravity, the solid powder raw material will automatically separate from the material trough 31 and fall into the main mixing barrel 1 through a group of feed ports 501 below, so that the solid powder is mixed with the liquid raw material in the main mixing barrel 1 to achieve material discharge, and then the electric push rod is controlled to repeatedly push and pull the discharge block 203, so that the solid powder raw material in the secondary mixing barrel 3 is intermittently added to the main mixing barrel 1. Compared with the prior art, the liquid raw material and the solid powder raw material are firstly mixed separately, and then the solid powder is intermittently and in small amounts added to the liquid raw material by repeatedly pushing and pulling the discharge block 203, so as to avoid agglomeration during mixing.

[0032] Furthermore, the blanking mechanism 2 also includes two sets of guide sleeves 204 , and the guide sleeves 204 on both sides are symmetrically arranged on both sides of the end of the blanking block 203 . The guide sleeves 204 are inserted into the guide pillars 205 , and one end of the guide pillars 205 is fixedly connected to the outer ring of the base 201 .

[0033] Specifically, when the blanking block 203 is pushed and pulled, the blanking block 203 will drive the guide sleeve 204 to slide back and forth along the guide pillar 205 , and the cooperation between the guide pillar 205 and the guide sleeve 204 guides the movement of the blanking block 203 .

[0034] Embodiment 2: Figure 3As shown, in contrast to Example 1, another embodiment of the present invention is: the unloading mechanism 2 also includes a first gear 206, the first gear 206 is fixedly mounted on the base 201, a second gear 207 meshing with the first gear 206, and the second gear 207 is rotatably mounted on one side of the base 201, a bent rod 208, one end of the bent rod 208 is connected to the end of the unloading block 203, an annular groove 502 is provided on the upper end surface of the main mixing barrel 1, and the other end of the bent rod 208 is located in the annular groove 502, the annular groove 502 is composed of four groups of arc grooves 5021 and four groups of V-shaped grooves 5022, and the axis of the arc groove 5021 is located on the central axis of the base 201.

[0035] Specifically, when the solid powder raw material is put into the main mixing barrel 1, the second gear 207 is driven by the motor to rotate, and the second gear 207 drives the first gear 206 to rotate together with the base 201, and the base 201 drives the material block 203 to rotate together with the bent rod 208 through the rectangular slot 202, and at the same time, the other end of the bent rod 208 will slide along the annular groove 502. During the sliding process, when the other end of the bent rod 208 slides into the V-shaped groove 5022, under the guidance of the V-shaped groove 5022, the bent rod 208 will first drive the material block 203 to rotate along the rectangular slot 202. The V-shaped slot 202 moves toward the inside of the secondary mixing barrel 3, and then the discharge block 203 moves back along the rectangular slot 202 to realize the above-mentioned material taking and placing. Since there are four groups of V-shaped grooves 5022, and the adjacent V-shaped grooves 5022 are connected by the arc groove 5021, not only can the solid powder raw material be intermittently added to the main mixing barrel 1, but also the solid powder raw material can be put into different areas of the main mixing barrel 1, so that the solid powder raw material can be put into the main mixing barrel 1 more evenly, thereby improving the mixing efficiency of the solid powder raw material and the liquid raw material.

[0036] like Figures 4 to 7As shown in the figure, the blanking block 203 includes a driven block 2031, the driven block 2031 is movably inserted into the rectangular slot 202, two groups of U-shaped clamps 2032 movably installed at one end of the driven block 2031, a receiving rod 2033 fixedly connected to one end of the U-shaped clamp 2032, a driving block 2034, both groups of receiving rods 2033 are inserted into the driving block 2034, two groups of guide sleeves 204 are respectively fixed on both sides of the driving block 2034, a movable plate 2035 movably installed in the driving block 2034, one end of a bent rod 208 is fixedly connected to the movable plate 2035, two groups of pressure-bearing blocks 2036, the two groups of pressure-bearing blocks 2036 are respectively fixed on both sides of the movable plate 2035, a spring 2037 arranged above the pressure-bearing block 2036, a first rectangular groove 341 and a second rectangular groove 342 are formed in the driving block 2034, the first rectangular groove 341 and the second rectangular groove 342 communicate with each other, both groups of receiving rods 2033 are located in the second rectangular groove 342, the movable plate 2035 is inserted into the first rectangular groove 341, a number of convex blocks 211 for pushing the bent rod 208 are arranged in each of the four arc grooves 5021, two groups of inclined grooves 351 are symmetrically formed in the movable plate 2035, a pin shaft 331 is arranged at one end of the receiving rod 2033, and the pin shaft 331 is located in the inclined groove 351.

[0037] Specifically, the material storage tank 31 is located between two sets of U-shaped clamps 2032. In order to promote the mixing of liquid raw materials, the main mixing barrel 1 is heated to raise the temperature of the liquid raw materials. The temperature rise will cause the water in the liquid raw materials to be volatilized in the form of water vapor, and the water vapor will adhere to the inner wall of the material storage tank 31. The solid powder raw materials enter the material storage tank 31. Since the inner wall of the material storage tank 31 is relatively wet, part of the solid powder raw materials adhere to the inner wall of the material storage tank 31. As the solid powder raw materials accumulate on the inner wall of the material storage tank 31, the internal space of the material storage tank 31 is reduced, affecting the efficiency of feeding the solid powder raw materials into the main mixing barrel 1. Therefore, when the feeding block 203 picks up and places materials, the bent rod 208 drives the movable plate 2035 to push and pull the entire feeding block 203. When the feeding block 203 picks up materials, the solid powder raw materials will enter between the two sets of U-shaped clamps 2032. When the feeding block 203 places materials, the two sets of U-shaped clamps 2032 are located outside the rectangular slot 202, and the driven block 2031 is located in the rectangular slot 202 and blocks the feeding port 21. When the other end of the bent rod 208 slides from the V-shaped groove 5022 to the arc-shaped groove 5021, the other end of the bent rod 208 will be squeezed by a set of convex blocks 211, pushing the bent rod 208 upward. At the same time, the bent rod 208 drives the movable plate 2035 and the two bearing blocks 2036 to move upward together. The bearing block 2036 will compress the spring 2037. During the upward movement of the movable plate 2035, the two pin shafts 331 slide along the two diagonal slots 351 respectively. Under the guidance of the diagonal slots 351, the two pin shafts 331 separate the two sets of U-shaped clamps 2032 through the two connecting rods 2033 until the U-shaped clamp 2032 hits the guide post 205. At this time, the other end of the bent rod 208错开 a set of convex blocks 211. Under the action of the rebounding force of the spring 2037, the two sets of U-shaped clamps 2032 merge and collide. Since there are multiple sets of convex blocks 211 arranged in the arc-shaped groove 5021, after the other end of the bent rod 208 passes through multiple sets of convex blocks 211, the two sets of U-shaped clamps 2032 will be impacted repeatedly. The impact will generate vibration, shaking off the raw materials adhering to the inner wall of the material storage tank 31, realizing the cleaning of the material storage tank 31 and ensuring that the efficiency of the feeding block 203 feeding the solid powder raw materials into the main mixing barrel 1 is not affected.

[0038] Further, a slide bar 343 is fixedly installed in the second rectangular groove 342. Through holes 332 are opened on both sets of connecting rods 2033, and both through holes 332 are inserted with the slide bar 343. A guiding groove 311 is opened at one end of the driven block 2031, and a guide rail 321 is arranged at the other end of the U-shaped clamp 2032. The guide rail 321 is slidably connected to the guiding groove 311.

[0039] Specifically, during the opening and closing process of the U-shaped fixture 2032, the through hole 332 on the receiving rod 2033 will slide along the sliding rod 343, and the guide rail 321 will slide along the guide groove 311. The cooperation between the sliding rod 343 and the through hole 332 and the cooperation between the guide rail 321 and the guide groove 311 both play a guiding role in the movement of the U-shaped fixture 2032.

[0040] Working principle: Add the liquid raw materials for making lithium battery slurry into the main mixing barrel 1, and then add the solid powder raw materials into the secondary mixing barrel 3. Drive the main shaft 4 to rotate through the motor. The main shaft 4 drives the secondary stirring shaft 6 and the main stirring shaft 7 to rotate together, so that the liquid raw materials in the main mixing barrel 1 and the solid powder raw materials in the secondary mixing barrel 3 are separately and independently mixed and stirred. After the liquid raw materials and the solid powder raw materials are both mixed evenly, keep the main shaft 4 rotating at a constant speed. Drive the second gear 207 to rotate through the motor. The second gear 207 drives the first gear 206 and the base 201 to rotate together. The base 201 drives the blanking block 203 and the bent rod 208 to rotate together through the rectangular slot 202. At the same time, the other end of the bent rod 208 will slide along the annular groove 502. During the sliding process, when the other end of the bent rod 208 slides into the V-shaped groove 5022, under the guidance of the V-shaped groove 5022, the bent rod 208 will first drive the blanking block 203 to move along the rectangular slot 202 towards the inside of the secondary mixing barrel 3 until the material receiving groove 31 on the blanking block 203 is located below the blanking port 21. At this time, the solid powder raw materials in the secondary mixing barrel 3 will flow through the blanking port 21 into the material receiving groove 31 to achieve material taking. Then, move the blanking block 203 back along the rectangular slot 202. Under the action of gravity, the solid powder raw materials will automatically separate from the material receiving groove 31 and fall into the main mixing barrel 1 through a set of feeding ports 501 below, so that the solid powder is mixed with the liquid raw materials in the main mixing barrel 1 to achieve discharging. Since there are four sets of V-shaped grooves 5022, and the adjacent V-shaped grooves 5022 are connected by the arc-shaped groove 5021, it can not only intermittently add the solid powder raw materials into the main mixing barrel 1, but also put the solid powder raw materials into different areas of the main mixing barrel 1;

[0041] When the other end of the bent rod 208 slides from the V-shaped groove 5022 into the arc-shaped groove 5021, the other end of the bent rod 208 will be squeezed by a set of bumps 211, causing the bent rod 208 to be pushed upward. At the same time, the bent rod 208 drives the movable plate 2035 and two sets of bearing blocks 2036 to move upward together. The bearing blocks 2036 will compress the spring 2037. During the upward movement of the movable plate 2035, the two sets of pin shafts 331 slide along the two sets of inclined grooves 351 respectively. Under the guidance of the inclined grooves 351, the two sets of pin shafts 331 separate the two sets of U-shaped clamps 2032 through the two sets of connecting rods 2033 until the U-shaped clamps 2032 hit the guide posts 205. At this time, the other end of the bent rod 208错开a set of bumps 211. Under the action of the rebounding force of the spring 2037, the two sets of U-shaped clamps 2032 merge and collide. Since there are multiple sets of bumps 211 provided in the arc-shaped groove 5021, after the other end of the bent rod 208 passes through multiple sets of bumps 211, the two sets of U-shaped clamps 2032 will be repeatedly impacted. The impact will generate vibration, causing the raw materials attached to the inner wall of the material storage tank 31 to fall off.
