A crucible for a lithium battery cathode material with adjustable capacity Technical Field
[0001] This utility model relates to the field of sagger technology, and more specifically, to a sagger for lithium battery positive electrode materials with adjustable capacity. Background Technology
[0002] The production process of lithium battery cathode materials generally adopts the high-temperature sintering method of roller kiln, and the most widely used calcining container in mass production is the sagger.
[0003] Patent document publication number CN220750823U discloses a sagger for calcining lithium battery cathode materials, comprising a sagger body and a cover plate. A support portion is fixedly provided at the top corner of the sagger body, and a ventilation notch is formed between the support portions. The cover plate has a groove and a ventilation hole, the groove matching the support portion, and the diameter of the ventilation hole at one end near the sagger body being larger than the diameter at the other end.
[0004] However, it still has some drawbacks in actual use, such as: the internal space of the sagger is fixed and cannot be adjusted, and it needs to be replaced when facing different production needs, which leads to its limited use and restricts the application scenarios of the sagger.
[0005] Therefore, a crucible for lithium battery cathode materials with adjustable capacity was proposed to solve the above problems. Summary of the Invention
[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a capacity-adjustable sagger for lithium battery cathode materials, so as to solve the problem that the internal space of the sagger in the prior art is fixed and cannot be adjusted, and needs to be replaced when facing different production needs, thus limiting its use and restricting the application scenarios of the sagger.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a crucible for lithium battery positive electrode materials with adjustable capacity, comprising...
[0008] Sagger body;
[0009] Movable edges, which are movably installed on both sides of the length direction of the sagger body;
[0010] An extension component is disposed inside the sagger body;
[0011] The extended assembly includes a motor, a rotating shaft, a gear, and a rack. The motor is fixedly installed on the front of the sagger body. One end of the rotating shaft is fixedly connected to the output end of the motor, and the other end of the rotating shaft is rotatably connected to the interior of the sagger body. The gear is fixedly sleeved on the outer surface of the rotating shaft, and the rack is fixedly installed at the bottom of the movable side. The gear meshes with the rack.
[0012] The discharge assembly is located at the bottom of the sagger body.
[0013] The discharge assembly includes a base plate, a hydraulic rod, a top block, a connecting column, a connecting plate, a spring, and a blocking rod. The bottom end of the hydraulic rod is fixedly connected to the top of the base plate, and the top end of the hydraulic rod is fixedly connected to the bottom of the sagger body. The top block is slidably installed on the bottom of the sagger body. The top end of the connecting column is fixedly connected to the bottom of the top block, and the bottom end of the connecting column is fixedly connected to the top of the connecting plate. The top end of the spring is fixedly connected to the bottom of the sagger body, and the bottom end of the spring is fixedly connected to the top of the connecting plate. The blocking rod is fixedly installed on the bottom of the connecting plate.
[0014] The discharge assembly also includes a force-bearing plate, which is fixedly installed on the top of the base plate, and the top of the force-bearing plate is in contact with the bottom end of the blocking rod.
[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0016] In the above scheme, a sagger body, a movable side, and an extension component are set up. The motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft then drives the gear to rotate. Since the gear meshes with the rack, the gear will drive the rack to move when it rolls, thereby causing the movable side to slide inside the sagger body and change the size of the internal space of the sagger body. Through the above structure, the internal space of the sagger body can be expanded or reduced as needed to achieve adjustable operation and expand the application scenarios.
[0017] The discharge assembly is set up so that after the lithium battery cathode material is processed, the hydraulic rod is activated. The hydraulic rod drives the main body of the sagger to move downward until the blocking rod contacts the force plate. At this time, the spring begins to contract, and the connecting column drives the top block to move upward, pushing the material out. Through the above structure, the processed material can be quickly removed, solving the problem of the material being stuck inside the sagger and difficult to remove. Attached Figure Description

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0027] As shown in Figures 1 to 4, an embodiment of this utility model provides a sagger for a lithium battery positive electrode material with adjustable capacity, comprising:
[0028] Sagger body 1;
[0029] Movable edge 2 is movably installed on both sides of the length direction of the sagger body 1;
[0030] Extension component 3 is disposed inside the sagger body 1;
[0031] The extension component 3 includes a motor 31, a rotating shaft 32, a gear 33, and a rack 34. The motor 31 is fixedly installed on the front of the sagger body 1. One end of the rotating shaft 32 is fixedly connected to the output end of the motor 31, and the other end of the rotating shaft 32 is rotatably connected to the inside of the sagger body 1. The gear 33 is fixedly sleeved on the outer surface of the rotating shaft 32, and the rack 34 is fixedly installed on the bottom of the movable side 2. The gear 33 and the rack 34 mesh with each other.
[0032] The discharge component 4 is located at the bottom of the sagger body 1.
[0033] The discharge assembly 4 includes a base plate 41, a hydraulic rod 42, a top block 43, a connecting column 44, a connecting plate 45, a spring 46, and a blocking rod 47. The bottom end of the hydraulic rod 42 is fixedly connected to the top of the base plate 41, and the top end of the hydraulic rod 42 is fixedly connected to the bottom of the sagger body 1. The top block 43 is slidably installed on the bottom of the sagger body 1. The top end of the connecting column 44 is fixedly connected to the bottom of the top block 43, and the bottom end of the connecting column 44 is fixedly connected to the top of the connecting plate 45. The top end of the spring 46 is fixedly connected to the bottom of the sagger body 1, and the bottom end of the spring 46 is fixedly connected to the top of the connecting plate 45. The blocking rod 47 is fixedly installed on the bottom of the connecting plate 45.
[0034] The discharge assembly 4 also includes a force plate 48, which is fixedly installed on the top of the base plate 41, and the top of the force plate 48 is in contact with the bottom end of the blocking rod 47.
[0035] As shown in Figure 4, the top block 43 is shaped with a larger top and a smaller bottom. This design restricts the movement direction of the top block 43, so that the top block 43 can only slide upward at the bottom of the sagger body 1 to push out the lithium battery positive electrode material.
[0036] The working process of this utility model is as follows: Start the motor 31, the motor 31 drives the rotating shaft 32 to rotate, the rotating shaft 32 then drives the gear 33 to rotate. Since the gear 33 meshes with the rack 34, when the gear 33 rolls, it will drive the rack 34 to move, thereby driving the movable side 2 to slide inside the sagger body 1, changing the size of the internal space of the sagger body 1.
[0037] After the lithium battery cathode material is processed, the hydraulic rod 42 is activated. The hydraulic rod 42 drives the sagger body 1 to move downward until the blocking rod 47 contacts the force plate 48. At this time, the spring 46 begins to contract, and the connecting column 44 drives the top block 43 to move upward, pushing the material out.
