Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a raw material mixing device for producing and processing lithium battery shells. Background Art

[0002] The lithium battery includes a cover plate structure, which includes a positive electrode column, a conductive sheet, a top cover plate and a plastic cover plate. The conductive sheet is connected to the positive electrode column, the positive electrode column and the top cover plate are insulated and assembled, and the plastic cover plate is connected to the top cover plate. The difference between lithium batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased, and high requirements have been placed on power sources. Lithium batteries have entered a large-scale practical stage. In the production process of lithium batteries, the first step is to mix the various raw materials used to make the lithium battery shell through a mixing device, and this mixing equipment used to mix the raw materials of the lithium battery shell can also be called a raw material mixing equipment for the production and processing of lithium battery shells;

[0003] Patent publication number CN220633912U in the prior art discloses a raw material mixing device for the production and processing of lithium battery shells. The device uses a first driving mechanism to rotate a stirring frame and a scraper, and the stirring frame can be used to stir and mix the raw materials of the lithium battery shells. The scraper can be used to clean the inner wall of the mixing tank, thereby reducing the possibility of waste of lithium battery shell raw materials, thereby solving the problem of insufficient raw material feeding.

[0004] However, after using this mixing equipment, the stirring frame needs to be cleaned before the next operation can be carried out. This is to avoid the residual material from contaminating or affecting the material to be mixed next time. During the cleaning process of the stirring frame, the equipment is in a shutdown state, which affects the processing efficiency of the equipment. Therefore, it does not meet the existing needs. We have proposed a raw material mixing equipment for the production and processing of lithium battery shells. Utility Model Content

[0005] The purpose of the utility model is to provide a raw material mixing device for the production and processing of lithium battery shells, so as to solve the problem proposed in the above background technology that after using this mixing device, the stirring frame needs to be cleaned before the next operation can be carried out. This is to avoid the residual material from polluting or affecting the material mixed next time. During the cleaning process of the stirring frame, the equipment is in a shutdown state, thereby affecting the processing efficiency of the equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material mixing device for the production and processing of lithium battery shells, comprising a circular motor base, a replacement motor is fixedly installed at the middle position of the upper end surface of the circular motor base, the output shaft of the replacement motor is connected with a lifting threaded rod, a connecting plate is provided on the outer side of the middle position of the outer surface of the lifting threaded rod, a circular through hole penetrating the connecting plate is provided at the middle position of the upper end surface of the connecting plate, a circular plate connected to the inner wall of the circular through hole through a roller bearing is provided inside the circular through hole, an internal threaded through hole penetrating the circular plate is provided at the middle position of the upper end surface of the circular plate, the lifting threaded rod vertically penetrates the internal threaded through hole, and the external thread of the lifting threaded rod matches the internal thread of the internal threaded through hole, and a guide rod vertically movable through the circular plate is provided on both sides of the lifting threaded rod;

[0007] A tank cover is fixedly arranged on the front and rear end surfaces of the connecting plate, and a mixing tank is arranged below the first tank cover from left to right.

[0008] Preferably, a stirring motor is fixedly installed in the middle position of the upper end surface of the tank cover, the output shaft of the stirring motor is connected to a transmission shaft through a coupling, the lower end surface of the transmission shaft is fixedly connected to a stirring frame, and the first stirring frame from left to right is located inside the mixing tank.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is that after the raw materials are mixed by the mixing tank, the outer surface of the stirring rack inside the mixing tank is stained with the raw materials. When the stirring rack inside the mixing tank needs to be cleaned, the circular plate and the connecting plate connected to the circular plate by the roller bearing and the two tank covers fixed to the front and rear end surfaces of the connecting plate can be moved upward by replacing the motor. As the tank cover rises, the stirring motor installed on the outer surface of the tank cover and the stirring rack connected thereto will also rise accordingly. Since the connecting plate and the circular plate are connected by the roller bearing, the connecting plate can be rotated by itself. When the stirring rack inside the mixing tank completely leaves the interior of the mixing tank, the connecting plate is manually rotated. When the connecting plate rotates one hundred and eighty degrees, the positions of the two stirring racks will be exchanged accordingly. Then, the clean stirring rack can be moved into the interior of the mixing tank by moving the circular plate downward again by replacing the motor. Later, in the process of using the mixing tank to mix new raw materials, the stirring rack stained with raw materials on the outer surface can be cleaned at the same time. Through the above technical solution, the gap during the operation of the mixing tank can be reduced, thereby improving its production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the lifting threaded rod 9 rotates, the circular plate 7, which cannot rotate by itself, will move up and down on the outer surface of the lifting threaded rod 9 through the internal thread transmission of the internal threaded through hole 13. At this time, the circular plate 7 is moved upward. During the upward movement of the circular plate 7, the connecting plate 5 connected to it by roller bearings and the two tank covers 2 fixed to the front and rear end surfaces of the connecting plate 5 will move upward synchronously. Since the connecting plate 5 and the circular plate 7 are connected by roller bearings, the connecting plate 5 can rotate by itself.

When the connecting plate 5 rotates 180 degrees, the bevel positioning block 11 at its front and rear ends is pushed outward due to its inclined surface. After the positions of the two tank covers 2 on the end faces are swapped, the inclined surface positioning block 11 can be again inserted into the inclined surface positioning groove 10 through the reaction force of the squeezed positioning spring 12, so as to complete the positioning of the tank cover 2. When the positioning of the tank cover 2 is completed, the clean stirring frame 4 can be moved into the interior of the mixing tank 1 by switching the motor 16 to move the circular plate 7 downward again. Later, in the process of using the mixing tank 1 to mix new raw materials, the stirring frame 4 contaminated with raw materials on the outer surface can be cleaned at the same time.
