Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an automatic weighing and unloading device for lithium battery raw materials. Background Technology

[0002] The raw materials for lithium-ion batteries mainly consist of four substances: active materials, conductive agents, binders, and solvents. The specific raw materials vary depending on the type of lithium-ion battery, the type of positive and negative electrodes, and whether it's oil-based or water-based. While general fluids only possess viscosity (pure viscous fluids), lithium-ion battery raw materials exhibit both viscosity and elasticity (viscoelastic fluids). The elasticity of lithium-ion battery raw materials plays a beneficial role in the coating process, preventing stringing. During coating, the broken filaments quickly rebound, resulting in a more uniform coating effect.

[0003] The production of lithium battery raw materials requires the use of a reaction vessel for stirring and mixing. After stirring, the material needs to be fed in and weighed. The bottom space of the reaction vessel is limited, and most existing feeding and weighing devices are fixed, making it difficult to remove the material after feeding and weighing.

[0004] Therefore, it is of great significance to provide an automatic weighing and unloading device for lithium battery raw materials to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an automatic weighing and unloading device for lithium battery raw materials, so as to solve the problem that most existing unloading and weighing devices are fixed and difficult to remove after the unloading and weighing are completed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic weighing and discharging device for lithium battery raw materials includes a base plate. A second fixed seat and a first fixed seat are fixedly connected to the two sides of the top of the base plate, respectively. A sliding rod is fixedly connected between the second fixed seat and the first fixed seat. A movable seat is slidably connected to the sliding rod. Lifting rods are slidably connected to both sides of the movable seat. A lifting plate is fixedly connected to the top of the lifting rod. A weighing sensor is installed at the top of the lifting plate. A fixed plate is installed at the top of the weighing sensor. A hinge is installed on one side of the top of the fixed plate, and a discharging hopper is hinged to the hinge. A support block is installed at the bottom of the discharging hopper, and a handle is fixedly connected to the side of the discharging hopper.

[0008] As a preferred embodiment of this utility model, a cylinder is installed in the middle of the top of the movable seat, and the telescopic end of the cylinder is fixedly connected to the lifting plate.

[0009] As a preferred embodiment of this utility model, a motor is installed on one side of the second fixed seat, a threaded rod is rotatably connected between the second fixed seat and the first fixed seat, the threaded rod is threadedly connected to the movable seat, and the output end of the motor is drivenly connected to the threaded rod.

[0010] As a preferred embodiment of this utility model, a proximity switch is installed on the inner side of the fixing base, and a transparent observation window is provided on the front of the hopper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The hopper in this utility model is movable. When in use, the hopper is moved to the bottom of the feed port of the reactor. After the material is discharged, it is weighed by a weighing sensor. After weighing, the hopper is removed from the feed port of the reactor and lifted by the handle to facilitate the discharge.

[0013] 2. The material hopper in this utility model can be raised and lowered. When the material is discharged from the reactor, if the height difference is too large, dust will be generated during the discharge. At the beginning of the discharge, the material hopper is raised by the cylinder to reduce the height difference. As the material in the material hopper increases, the height of the material hopper is gradually lowered to reduce dust generation.

[0014] 3. This utility model can perform lateral reciprocating motion of the hopper during material feeding, resulting in more uniform material distribution in the hopper and more accurate weighing.

[0015] The above description is only an overview of the technical solution of this application.

[0025] Please see Figure 1-2This utility model provides a technical solution for an automatic weighing and feeding device for lithium battery raw materials: it includes a base plate 1, with a fixed seat 2 16 and a fixed seat 1 7 fixedly connected to the two sides of the top of the base plate 1, a slide rod 15 fixedly connected between the fixed seat 2 16 and the fixed seat 1 7, a movable seat 4 slidably connected to the slide rod 15, lifting rods 5 slidably connected to the two sides of the movable seat 4, a lifting plate 6 fixedly connected to the top of the lifting rod 5, a weighing sensor 8 (model EY-M8-425H-8T) installed at the top of the lifting plate 6, a fixed plate 11 installed at the top of the weighing sensor 8, a hinge 10 installed on one side of the top of the fixed plate 11, a feeding hopper 12 hinged to the hinge 10, a support block 13 installed at the bottom of the feeding hopper 12, and a handle 14 fixedly connected to the side of the feeding hopper 12.

[0026] A cylinder 3 is installed at the center of the top of the movable seat 4, and the telescopic end of the cylinder 3 is fixedly connected to the lifting plate 6.

[0027] A motor 9 is installed on one side of the fixed base 2 16. A threaded rod 2 is rotatably connected between the fixed base 2 16 and the fixed base 1 7. The threaded rod 2 is threadedly connected to the movable base 4. The output end of the motor 9 is connected to the threaded rod 2 for transmission.

[0028] A proximity switch is installed on the inside of the fixed seat 7 to detect the position of the movable seat 4. A transparent observation window is set on the front of the hopper 12 to facilitate observation of the material height.

[0029] In practical use, during material feeding, the hopper 12 is located below the feed port of the reactor. The motor 9 drives the threaded rod 2 to rotate, and the threaded rod 2 can drive the movable seat 4 to move left and right, so that the feeding point moves continuously and the material is more evenly distributed in the hopper 12. At the same time, the cylinder 3 drives the lifting plate 6 to rise, so that the feed pipe of the reactor is close to the bottom of the hopper 12. As the feeding process proceeds, the hopper 12 gradually descends in height. After the feeding is completed, the weight is measured by the weighing sensor 8. After reading the data, the movable seat 4 moves to the rightmost side, and the hopper 12 is lifted by the handle 14 to complete the feeding.
