Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln sintering technology, specifically to a sagger track fixing device. Background Technology
[0002] The production of ternary cathode materials primarily utilizes a track-type continuous sintering kiln for high-temperature solid-state reactions. The core process involves a roller drive system that continuously moves ceramic saggers within the kiln. Specifically, after mixing and pressing, the material is loaded into high-temperature resistant ceramic saggers and then fed into the tunnel-type kiln via an automated conveyor line. The kiln is divided into preheating, high-temperature sintering, and slow cooling zones, with the saggers propelled by rollers at a constant speed through each zone. During single-batch production, the saggers are closely arranged to form a continuous material flow, and a temperature control system enables the directional growth of the material's crystal structure.
[0003] In related technologies, the tightly fitted structure of the saggers obstructs the emission of lower-layer exhaust gases. Because only a basic thermal expansion gap remains between the sagger layers, and exhaust gases are released during material sintering, these gaseous byproducts create localized high-pressure zones within the confined space. Due to the physical obstruction from the upper saggers, the exhaust gases generated in the lower saggers cannot be effectively discharged through natural convection, causing them to accumulate at the bottom of the saggers and form a stagnant layer, resulting in an increased batch scrap rate. Utility Model Content
[0004] In view of this, the present invention provides a sagger track fixing device to solve the problem of air leakage during sagger transportation due to tight fit.
[0005] This utility model provides a sagger-mounted track fixing device, comprising:
[0006] A conveying platform, adapted to convey crucibles along a first direction;
[0007] Rollers, multiple rollers are arranged side by side on the upper surface of the conveying platform along a first direction, all rollers are parallel to the second direction in their length direction, some rollers are suspended in the second direction beyond the upper surface area of the conveying platform, and at least two protrusions are provided on the rollers along their length direction. The protrusions are cylindrical structures and their axes coincide with the roller axis.
[0008] An adjustment device is provided at at least one end of each roller, which is suitable for monitoring and adjusting the relative position of the roller and the conveying platform.
[0009] Beneficial effects: The combination of rollers and adjusting device improves the stability and position control accuracy of the crucible conveyor. The roller structure, arranged side-by-side along the conveying direction and complemented by cylindrical protrusions, ensures continuous conveying while increasing the spacing between the side-by-side crucibles through the baffles formed by the protrusions. This allows exhaust gas generated in the crucibles to be naturally discharged via convection through the increased spacing. The coaxial structure of the protrusions and rollers ensures dynamic balance performance during operation. The adjusting device enables real-time position monitoring and dynamic compensation, instantly correcting horizontal deviations and axial offsets of the rollers, thus solving the problem of accumulated errors caused by long-term operation in traditional conveying systems.
[0010] In one optional embodiment, the roller bar further includes a roller bar body, and a buffer portion is provided at the junction of the roller bar body and the protrusion, the buffer portion connecting both the roller bar body and the protrusion.
[0011] Beneficial effects: By adding a buffer section, the roller improves the smoothness of equipment operation and the service life of components. The buffer section forms a flexible transition zone between the roller body and the protrusion, which can effectively absorb the impact vibration generated by the sagger during the conveying process, reduce the instantaneous stress peak when the protrusion contacts the sagger, and make the load distribution more uniform.
[0012] In one optional embodiment, the adjusting device includes an adjusting plate that is connected to a suspended roller. The adjusting plate is disposed on the side of the conveying platform and is symmetrically arranged on both sides of the roller along the roller axis.
[0013] Beneficial effects: This adjustment device, through its symmetrically arranged adjustment plates, achieves dynamic calibration and stable support for the suspended rollers. The bidirectional constraint structure, with the adjustment plates symmetrically distributed along the roller axis, reduces the radial offset distance of the suspended roller section.
[0014] In one alternative embodiment, the adjusting device further includes an adjusting plate, which is connected to the adjusting plate and is adapted to adjust the relative position of the adjusting plate with respect to the roller in a second direction.
[0015] Beneficial effects: The adjustment device achieves dynamic calibration of the roller position by adding an adjustable adjustment plate structure. The adjustment plate provides basic positioning support, while the adjustment plate can achieve fine adjustment, thereby improving the centering accuracy of the roller.
[0016] In one optional embodiment, the adjusting plate is provided with a first sliding part and a first fixing part, and the adjusting piece is provided with a second sliding part and a second fixing part. The second sliding part and the first sliding part are slidably connected along a second direction, and the first fixing part and the second fixing part are adapted to fix the adjusting piece and the adjusting plate.
[0017] Beneficial effects: The adjusting device achieves precise adjustment and reliable locking of the roller position through the sliding part and the fixed part. The first sliding part and the second sliding part can achieve smooth linear displacement adjustment in the second direction, while the first fixed part and the second fixed part ensure positioning stability through uniformly distributed fastening force.
[0018] In one alternative embodiment, the buffer portion is a rounded corner at the junction of the roller body and the protrusion.
[0019] Beneficial effects: By setting rounded corners at the junction of the roller body and the protrusion, the operational reliability of the equipment is improved. The rounded corner transition design reduces stress concentration, effectively avoiding fatigue cracking problems caused by traditional right-angle connections. While maintaining overall rigidity, it can smoothly disperse dynamic loads during the conveying process, reducing the contact impact force between the protrusion and the crucible.
[0020] In one alternative embodiment, the adjusting piece has a U-shaped structure, with both ends bent to form a second sliding portion.
[0021] Beneficial effects: The U-shaped structure of the adjustment plate forms an integrated second sliding part by bending at both ends. The U-shaped body structure improves the bending stiffness and effectively prevents elastic deformation during the adjustment process. Compared with the traditional single-sided adjustment structure, the bent sliding part reduces lateral sway.
[0022] In one alternative embodiment, the protrusion and the roller body are integrally formed.
[0023] Beneficial effects: The roller adopts a design in which the protrusion and the roller body are integrally formed. Through the integral casting process, the structure is seamlessly connected, which completely eliminates the weak connection points of the traditional split structure, improves the overall bending strength of the roller, and at the same time, the integral forming ensures that the protrusion and the body achieve improved coaxiality accuracy.
[0024] In one alternative embodiment, rollers arranged side by side form a conveying plane, and the rollers arranged side by side are arranged in multiple layers to form multiple conveying planes, with each layer of conveying planes connected by a rigid structure.
[0025] Beneficial effects: The three-dimensional layout design improves space utilization and conveying efficiency. The rigidly connected multi-layer conveying plane structure increases the effective conveying area within the same floor space, while the multi-layered, independently controllable conveying planes allow for the synchronous, layered conveying of crucibles of different sizes.
[0026] In one alternative implementation, the rollers are connected to a drive structure to enable crucible conveying.
[0027] Beneficial effects: By connecting the drive structure and the rollers, the conveying power is provided to the rollers, achieving efficient and stable saucer conveying performance. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0040] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0041] The production of ternary cathode materials primarily employs a track-type continuous sintering kiln for high-temperature solid-state reactions, with its core process relying on a roller drive system. This system uses precisely designed rollers to support high-temperature resistant ceramic saggers, enabling the saggers to move continuously at a constant speed within the kiln. The production process begins with material mixing and pressing, followed by loading the material into ceramic saggers and then conveying it into the tunnel kiln via an automated conveyor line. The kiln's interior is divided into multiple functional temperature zones according to process requirements, including a preheating zone, a high-temperature sintering zone, and a slow cooling zone. Driven by rollers, the saggers sequentially traverse different temperature zones, with a temperature control system precisely regulating the temperature profiles of each zone to ensure the directional growth of the material's crystal structure. During single-batch production, the saggers are closely arranged to form a continuous material flow, enabling efficient large-scale production.
[0042] However, the tightly fitted design of the saggers obstructs the discharge of waste gas from the lower layer, becoming a critical issue in the process. Because only a basic thermal expansion gap exists between the sagger layers, and the material releases a large amount of gaseous byproducts during sintering, these waste gases create localized high-pressure zones within the confined space. Especially in the lower sagger region, the waste gas is physically blocked by the upper sagger layers and cannot be effectively discharged through natural convection. This poor venting causes waste gas to accumulate at the bottom of the sagger, forming a stagnant layer. This not only interferes with the uniformity of the sintering reaction but may also lead to material defects. Ultimately, the waste gas stagnation problem significantly increases the scrap rate of batches, affecting production efficiency and product quality.
[0043] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.
[0044] According to an embodiment of the present invention, a sagger track fixing device is provided, comprising: a conveying platform 2, the conveying platform 2 being adapted to convey saggers along a first direction; rollers 1, a plurality of rollers 1 being arranged side by side along the first direction on the upper surface of the conveying platform 2, all rollers 1 having their length direction parallel to a second direction, and some rollers 1 being suspended beyond the upper surface area of the conveying platform 2 along the second direction, the rollers 1 having at least two protrusions 12 along their length direction, the protrusions 12 having a cylindrical structure, the axis of which coincides with the axis of the rollers 1; and an adjusting device 3, the adjusting device 3 being disposed at at least one end of each roller 1, adapted to monitor and adjust the relative position of the rollers 1 and the conveying platform 2.
[0045] The combination of rollers 1 and adjusting device 3 improves the stability and position control accuracy of the crucible conveying. The rollers 1, arranged side-by-side along the conveying direction, combined with cylindrical protrusions 12, ensure continuous conveying while increasing the spacing between the side-by-side crucibles through the baffles formed by the protrusions 12. This allows exhaust gas generated in the crucibles to be naturally discharged through convection. The coaxial structure of the protrusions 12 and rollers 1 ensures dynamic balance during operation. The adjusting device 3 enables real-time position monitoring and dynamic compensation, instantly correcting the horizontal deviation and axial offset of the rollers 1, thus solving the problem of accumulated errors caused by long-term operation in traditional conveying systems.
[0046] In some embodiments, combined with Figure 1 As shown, the roller 1 also includes a roller body 11. A buffer section 13 is provided at the junction of the roller body 11 and the protrusion 12, and the buffer section 13 connects the roller body 11 and the protrusion 12. By adding the buffer section 13, the roller 1 improves the smoothness of equipment operation and the service life of components. The buffer section 13 forms a flexible transition zone between the roller body 11 and the protrusion 12, which can effectively absorb the impact vibration generated by the sagger during the conveying process, reduce the instantaneous stress peak when the protrusion 12 contacts the sagger, and make the load distribution more uniform.
[0047] Furthermore, the buffer section 13 is a rounded corner at the junction of the roller body 11 and the protrusion 12. By setting a rounded corner at the junction of the roller body 11 and the protrusion 12, the operational reliability of the equipment is improved. The rounded corner transition design reduces stress concentration, effectively avoiding fatigue cracking problems caused by traditional right-angle connections. While maintaining overall rigidity, it can smoothly disperse the dynamic load during the conveying process, reducing the contact impact force between the protrusion 12 and the sagger.
[0048] Roller 1 is connected to the drive structure to achieve crucible conveying. The connection between the drive structure and roller 1 provides conveying power to roller 1, achieving efficient and stable crucible conveying performance.
[0049] It is worth noting that the protrusion 12 and the roller body 11 are integrally formed. The roller 1 adopts the design of integrally forming the protrusion 12 and the roller body 11. Through the integral casting process, the structure is seamlessly connected, which completely eliminates the weak connection points of the traditional split structure, improves the overall bending strength of the roller 1, and at the same time, the integral forming ensures that the protrusion 12 and the body achieve improved coaxiality accuracy.
[0050] During transportation, the sagger is transported along the first direction. In the second direction, due to the blocking of the protrusion 12, there is a gap between adjacent saggers so that the exhaust gas can be discharged in time. The rounded corner is set at the junction of the sagger, the protrusion 12 and the roller body 11, which helps to reduce the instantaneous stress on the sagger by the sagger, the protrusion 12 and the roller body 11.
[0051] In some embodiments, combined with Figure 5 and Figure 6 As shown, the adjustment device 3 includes an adjustment plate 31, which is connected to the suspended roller 1. The adjustment plate 31 is disposed on the side of the conveying platform 2 and symmetrically arranged on both sides of the roller 1 along the axis of the roller 1. This adjustment device 3, through the symmetrical arrangement of the adjustment plates 31, achieves dynamic calibration and stable support for the suspended roller 1. The bidirectional constraint structure of the adjustment plates 31, symmetrically distributed along the axis of the roller 1, reduces the radial offset distance of the suspended section of the roller 1.
[0052] Furthermore, the adjustment device 3 also includes an adjustment plate 32, which is connected to the adjustment plate 31. The adjustment plate 32 is adapted to adjust the relative position of the roller 1 along the second direction. By adding the adjustable adjustment plate 32, the adjustment device 3 achieves dynamic calibration of the position of the roller 1. The adjustment plate 31 provides basic positioning support, while the adjustment plate 32 enables fine adjustment, thereby improving the centering accuracy of the roller 1.
[0053] Furthermore, the adjusting plate 31 is provided with a first sliding part 311 and a first fixing part 312, and the adjusting piece 32 is provided with a second sliding part 321 and a second fixing part 322. The second sliding part 321 is slidably connected to the first sliding part 311 along a second direction, and the first fixing part 312 and the second fixing part 322 cooperate to fix the adjusting piece 32 to the adjusting plate 31. The adjusting device 3 achieves precise adjustment and reliable locking of the position of the roller 1 through the sliding part and the fixing part. The first sliding part 311 and the second sliding part 321 can achieve smooth linear displacement adjustment in the second direction, while the first fixing part 312 and the second fixing part 322 ensure positioning stability through a uniformly distributed fastening force.
[0054] As one feasible form, the adjusting plate 31 is a cuboid plate structure, with one end fixedly connected to the conveying platform 2. A groove is formed on the surface of the cuboid. The adjusting piece 32 has a U-shaped structure, with both ends bent to form a second sliding part 321. The U-shaped structure of the adjusting piece 32, through bending at both ends to form an integrated second sliding part 321, improves bending stiffness and effectively prevents elastic deformation during adjustment. Compared to the traditional single-sided adjusting structure, the bent sliding part reduces lateral sway.
[0055] Optionally, the adjustment plate 31 and the adjustment piece 32 can be fitted together by a slider groove. When it is necessary to fix the adjustment piece 32 to the adjustment plate 31, it can be fixed by an adjustable bolt and nut. The first fixing part 312 and the second fixing part 322 are through holes, and the bolt passes through the through holes to achieve the fixing effect.
[0056] In some embodiments, combined with Figure 1 As shown, the protrusion 12 and the roller body 11 are integrally formed. The roller 1 adopts the design of integrally forming the protrusion 12 and the roller body 11. Through the integral casting process, the structure is seamlessly connected, which completely eliminates the weak connection points of the traditional split structure, improves the overall bending strength of the roller 1, and at the same time, the integral forming ensures that the protrusion 12 and the body achieve improved coaxiality accuracy.
[0057] In some embodiments, combined with Figure 1 As shown, the rollers 1 arranged side by side form a conveying plane. Multiple layers of rollers 1 are arranged side by side to form multiple conveying planes, and each layer is connected by a rigid structure. This three-dimensional layout design improves space utilization and conveying efficiency. The rigidly connected multi-layer conveying plane structure increases the effective conveying area within the same floor space. Simultaneously, the multiple independently controllable conveying planes allow for the synchronous, layered conveying of crucibles of different specifications.
[0058] In actual operation, the distance between the adjusting plate 32 and one end of the roller 1 is generally preset to 1-2mm. The distance is monitored in real time by a sensor. At the same time, the adjusting plate 32 also plays a positioning role, which makes it easy to adjust the position of the roller 1 relative to the conveying platform 2 during transportation.
[0059] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
