[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4This utility model provides a box furnace for multi-station sintering with partitions, including an outer box 1, an inner box 2, a roller assembly 3, and a transmission assembly 4. The inner box 2 is disposed inside the outer box 1, and a receiving space 5 is formed between the outer side of the inner box 2 and the inner side of the outer box 1. The roller assembly 3 is rotatably connected to the inner box 2 and is used to carry the saggers and transport them by rotation. The power input end of the roller assembly 3 extends to the receiving space 5 and is connected to the power output end of the transmission assembly 4. The power input end of the transmission assembly 4 extends to the outer side of the outer box 1 and is used for manual power transmission.

[0024] The power input end of the transmission component 4 in this application extends to the outside of the outer casing 1, and the power is delivered manually, which saves the development cost of full automation, while meeting the needs of low-frequency and variable testing, thus greatly saving costs.

[0025] Furthermore, this application includes multiple workstations for placing saggers inside the inner box 2. These workstations are distributed in different areas within the inner box 2, supporting simultaneous processing of different materials or different stages of the same material. The roller assembly 3 transports the saggers from the entrance of the inner box 2 to different areas within the inner box 2, ensuring precise conveying and continuous feeding.

[0026] According to some embodiments of the present invention, the roller assembly 3 includes a hollow roller 31, a drive shaft 32, and a spring 33. The hollow roller 31 has a hollow structure. The drive shaft 32 is rotatably connected to the inner box 2. One end of the drive shaft 32 is inserted into the hollow roller 31, and the other end extends to the accommodating space 5 as a power input end and is connected to the power output end of the transmission assembly 4. A limiting ring 321 protrudes from the drive shaft 32. One end of the spring 33 abuts against the end face of the hollow roller 31, and the other end abuts against the limiting ring 321. The limiting ring 321 is used to compress the spring 33. The spring 33 is used to transmit power to the hollow roller 31 when the drive shaft 32 rotates.

[0027] It is understood that the roller assembly 3 for conveying lithium battery materials consists of a series of parallel, equidistant hollow rollers 31. Each hollow roller 31 traverses the inner box 2 and is rotatably supported on both sides of the inner box 2. The transmission assembly 4 enables the hollow rollers 31 to rotate in the same direction. The sagger is placed on the hollow rollers 31.

[0028] During sintering, a protective atmosphere or reaction is required. To ensure the kiln atmosphere meets process requirements, a closed firing system is necessary. This results in a small kiln space, heavy individual products, high firing temperatures, and complex operating conditions. During operation, if the weight or volume of the saggers loaded in a single load exceeds the load-bearing capacity of the roller assembly 3, or if the saggers are unevenly distributed on the rollers (e.g., piled up on one side), localized stress concentration may occur. Additionally, at high temperatures, some materials may melt or clump together and adhere to the surface of the roller assembly 3, increasing rolling resistance. The roller assembly 3 is also prone to breakage due to overload. Therefore, in this embodiment, the hollow roller 31 is pressed together by the elastic force of the spring 33. When the drive shaft 32 rotates, the limiting ring 321 also rotates. Under the elastic force of the spring 33, the friction between the limiting ring 321 and the spring 33 drives the spring 33 to rotate. The friction between the spring 33 and the hollow roller 31 then drives the hollow roller 31 to rotate. When the hollow roller 31 is overloaded, the resistance it experiences is greater than the friction between it and the spring 33, causing relative rotation between the hollow roller 31 and the spring 33, which effectively leads to the breakage of the roller.

[0029] According to some embodiments of this utility model, the drive shaft 32 is further provided with a sprocket 322, and the drive shaft 32 has a plurality of sprockets 322 connected by a chain 323. In this embodiment, the meshing between the chain 323 and the sprocket 322 is stable. Compared with belt drive, the chain 323 will not suffer from loss of transmission efficiency due to stretching or slippage, avoiding the slippage phenomenon that may occur with belts. In addition, since the test environment of the box furnace is at a high temperature, the steel structure of the chain 323 allows it to withstand high temperatures without deformation.

[0030] According to some embodiments of the present invention, the transmission shaft 32 extends to one end of the accommodating space 5 and is provided with a first gear 324. The transmission assembly 4 includes a second gear 41 and a rotating shaft 42. One end of the rotating shaft 42 is connected to the second gear 41, and the other end extends to the outside of the outer casing 1. The first gear 324 and the second gear 41 mesh with each other.

[0031] Preferably, both the first gear 324 and the second gear 41 are bevel gears, and the central axis of the transmission shaft 32 is perpendicular to the central axis of the rotation shaft 42. In this embodiment, the transmission direction of power is changed by bevel gears. For example, the hollow roller 31 is arranged along the length of the inner box 2, and under the action of the bevel gears, the rotation shaft 42 can be arranged along the depth of the outer box 1. Therefore, in practical applications, it is convenient for test personnel to observe the conveying of the sagger in the inner box 2 while rotating the rotation shaft 42.

[0032] According to some embodiments of this utility model, a hand crank 43 is provided at one end of the rotating shaft 42 extending to the outer side of the outer casing 1. The hand crank 43 can be held by hand and transmits power through rotation. In this embodiment, the hand crank 43, through its connection with the rotating shaft 42, converts human power into mechanical energy, thereby driving components such as the chain 323 and sprocket 322 to operate. Specifically, the hand crank includes a handle and a wheel body. The handle is rotatably connected to the wheel body, and the central axis of the handle is perpendicular to the side of the outer casing 1 and located away from the outer casing 1. The surface of the handle is designed with anti-slip textures or rubber coating to enhance grip comfort. The main body of the wheel body is a disc, the center of which is connected to the rotating shaft 42.

[0033] Furthermore, the rotating shaft 42 is rotatably connected to the bearing seat 44.

[0034] According to some embodiments of the present invention, the inner box 2 is provided with a support platform 21 on its inner side, and the support platform 21 is used to support the hollow roller 31.

[0035] Preferably, the support platform 21 is provided with an arc-shaped groove 211, and the hollow roller 31 is housed within the arc-shaped groove 211. It can be understood that the arc-shaped groove 211 fits against the outer periphery of the hollow roller 31, providing effective support for the hollow roller 31 and reducing the load on the drive shaft 32.

[0036] According to some embodiments of this utility model, a protective cover 22 is provided on the outer side of the inner box 2, and the drive shaft 32 is rotatably connected to the protective cover 22. A heat exchange space 23 is formed between the inner side of the protective cover 22 and the outer side of the inner box 2. A heat exchanger 24 is provided in the heat exchange space 23 to absorb the heat in the heat exchange space 23. During the test, the inner side of the inner box 2 will generate high temperature, and while the crucible is heated at high temperature, components such as the hollow roller 31, spring 33, and drive shaft 32 will also be heated. Since the drive shaft 32 extends into the receiving space 5, heat will also be dissipated into the receiving space 5. Pipes and lines are usually installed in the receiving space 5, and the heat dissipated into the receiving space 5 through the drive shaft 32 may damage the lines in the receiving space 5. Therefore, the protective cover 22 can effectively isolate the heat, and at the same time, the heat in the anti-slip cover is carried away by the heat exchanger 24. Specifically, the heat exchanger 24 can replace the hot water pipe, through which water flows to carry away the heat inside the protective cover 22, thus completing the heat exchange.

[0037] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
