Description
Technical Field
[0001] This utility model relates to the technical field of ceramic processing, and in particular to a special kiln car for ceramic products. Background Technology
[0002] Kiln cars are an important component of tunnel kilns, used to load products to be fired and move within the kiln. The design of kiln cars must consider stability and durability under high-temperature environments; therefore, they are typically made of refractory materials. When sintering ceramic glazes, the glazes are often sintered directly on kiln cars made of marble or refractory bricks.
[0003] However, placing ceramic glaze directly on the kiln car leads to several problems. First, under high temperatures, the heat inside the glaze is difficult to dissipate effectively, causing heat buildup. Second, this heat buildup not only affects the uniform sintering of the glaze but also causes localized overheating, thus reducing its performance and quality. Utility Model Content
[0004] This utility model solves the problems in related technologies and proposes a special kiln car for ceramic products. It utilizes ventilation holes on the support panel to transfer heat from the glaze sintering process to the heat dissipation holes in the support frame, allowing the heat to be discharged through these holes. Air circulation between the support frame and the support panel is achieved through an exhaust channel, facilitating timely heat dissipation during sintering and effectively ensuring the quality of the ceramic glaze sintering. Furthermore, the support component facilitates the connection between the support plate and the drive assembly, enabling the drive assembly to automatically move the support plate within the tunnel kiln, delivering the ceramic glaze to the sintering position and thus effectively ensuring the efficiency of ceramic glaze processing.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a special kiln car for ceramic products, including a support plate for placing ceramic glaze and a support assembly for supporting the support plate.
[0006] The support plate includes a support frame connected to the support assembly, a support panel disposed on the upper end face of the support frame, ventilation holes evenly disposed on the support panel, heat dissipation holes disposed on the lower end face of the support frame, an exhaust channel disposed between the outer periphery of the support panel and the inner cavity of the support frame, and a connecting assembly disposed between the support frame and the support panel. The support frame and the support panel are respectively made of heat-resistant brick material.
[0007] The support assembly includes a support member connected to the lower end face of the support frame and a drive assembly for driving the support member.
[0008] By adopting the above technical solution, the support plate consists of a support panel and a support frame for placing the ceramic glaze, and the two are connected by a connecting component. The heat generated during the sintering process of the glaze is transferred to the heat dissipation holes of the support frame through the ventilation holes on the support panel, and the heat is discharged through the heat dissipation holes. Air circulation between the support frame and the support panel is achieved through the exhaust channel, which facilitates the timely discharge of heat during the sintering process and effectively ensures the quality of sintering the ceramic glaze. In addition, the support component facilitates the connection between the support plate and the drive component, which allows the support plate to move automatically in the tunnel kiln and deliver the ceramic glaze to the sintering position, thereby effectively ensuring the efficiency of processing the ceramic glaze.
[0009] As a preferred embodiment, the outer diameter of the support panel is smaller than the inner diameter of the support frame.
[0010] By adopting the above technical solution, this design facilitates the formation of exhaust channels, which in turn facilitates air convection between the support panel and the support frame, thus facilitating heat dissipation.
[0011] As a preferred embodiment, the connecting assembly includes a limiting post fixedly disposed on the lower end face of the support panel and a limiting retaining ring fixedly disposed around the inner cavity of the support frame. The limiting retaining ring is provided with a limiting hole adapted to the limiting post. The limiting retaining ring is disposed circumferentially around the inner cavity of the support frame and is disposed in the upper middle part of the inner cavity of the support frame.
[0012] By adopting the above technical solution, the limiting post and the limiting hole on the limiting ring are fixedly connected, so that the support frame can be stably arranged around the support panel. The limiting ring is symmetrically distributed around the inner cavity of the support frame and is located in the upper middle position, which ensures the relative position stability between the support panels, effectively prevents the support frame from shifting or deflecting, and facilitates the transfer of heat to the ventilation holes on the support panel, and realizes air convection through the exhaust channel, thereby improving the heat dissipation efficiency.
[0013] As a preferred embodiment, the support includes a first guide rail, a second guide rail mirror-arranged relative to the first guide rail, mounting brackets respectively disposed at both ends of the lower end face of the support frame, movable rollers respectively disposed on the outer side of the mounting brackets, and a support frame disposed on the lower end face of each of the mounting brackets. The movable rollers are adapted to the first guide rail and the second guide rail, and the first guide rail and the second guide rail are configured as "U"-shaped.
[0014] By adopting the above technical solution, and by setting the first guide rail and the second guide rail, which are mirror images of each other and have a "U" shape, the moving rollers can be adapted to them, realizing a hidden design. This effectively avoids the impact of high temperature environment on the moving rollers, thereby ensuring the stability of the support panel when moving.
[0015] As a preferred embodiment, the drive assembly is disposed at the discharge end of the tunnel kiln. The drive assembly includes a rack for connecting to the mounting frame, a drive gear meshing with the rack, a rotating shaft disposed between the first guide rail and the second guide rail and connected to the drive gear, and a drive motor connected to the rotating shaft. A ball bearing is provided at the connection between the rotating shaft and the first guide rail and the second guide rail.
[0016] As a preferred embodiment, the drive motor is configured as a forward and reverse reversible motor, the drive motor is fixedly mounted on the outside of the first guide rail, and the output shaft of the drive motor is connected to the rotating shaft.
[0017] By adopting the above technical solution, the drive assembly is set at the discharge end of the tunnel kiln. Its working principle and technical effects are as follows: The drive assembly includes a rack, a drive gear, a rotating shaft, and a drive motor. The drive motor is fixed to the outside of the first guide rail and connected to the rotating shaft through an output shaft, enabling forward and reverse rotation. When the drive motor starts and rotates, the rotating shaft rotates accordingly, and the drive gear rotates and meshes with the rack installed between the first and second guide rails. This causes the mounting frame to move with the rack, thereby driving the support panel to move smoothly laterally within the tunnel kiln, delivering the ceramic glaze to the sintering position. This achieves automated and efficient conveying, improving production efficiency and product quality.
[0018] Compared with the prior art, the beneficial effects of this utility model are: This utility model;
[0019] The support plate is supported and driven by the support components, which consist of a support panel and a support frame. The two are connected by a connecting component. The support panel is provided with vent holes to transfer the heat generated during the glaze sintering process to the support frame. The lower end face of the support frame is provided with heat dissipation holes to expel the heat to the outside. An exhaust channel is also provided between the support frame and the support panel to maintain air circulation, effectively dissipate the heat during the sintering process, and ensure the glaze sintering quality.
[0020] In addition, the support component facilitates the connection between the support plate and the drive assembly. The drive assembly drives the support plate to move in the tunnel kiln, delivering the glaze to the sintering position for processing, thereby improving processing efficiency.

[0029] like Figures 1 to 5 As shown, a special kiln car for ceramic products includes a support plate for placing ceramic glaze and a support assembly for supporting the support plate.
[0030] Please refer to details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The support plate includes a support frame 41 connected to the support assembly, a support panel 42 disposed on the upper end face of the support frame 41, ventilation holes 421 evenly disposed on the support panel 42, heat dissipation holes 411 disposed on the lower end face of the support frame 41, an exhaust channel 43 disposed between the outer periphery of the support panel 42 and the inner cavity of the support frame 41, and a connecting assembly disposed between the support frame 41 and the support panel 42. The support frame 41 and the support panel 42 are respectively made of heat-resistant brick material.
[0031] Please refer to details. Figure 2 , Figure 3 , Figure 4 and Figure 5 The support assembly includes a support member connected to the lower end face of the support frame 41 and a drive assembly for driving the support member. In this invention, the support plate consists of a support panel 42 for placing the ceramic glaze and a support frame 41, which are connected by a connecting assembly. The heat generated during the sintering process of the glaze is transferred from the vent holes 421 on the support panel 42 to the heat dissipation holes 411 on the support frame 41. The heat is then discharged through the heat dissipation holes 411, and air circulation is achieved between the support frame 41 and the support panel 42 through the exhaust channel 43. This facilitates the timely discharge of heat during the sintering process and effectively ensures the quality of the ceramic glaze sintering. In addition, the support member facilitates the connection between the support plate and the drive assembly, thereby enabling the support plate to move automatically within the tunnel kiln and deliver the ceramic glaze to the sintering position, thus effectively ensuring the efficiency of the ceramic glaze processing.
[0032] Please refer to details. Figure 4 and Figure 5 The outer diameter of the support panel 42 is smaller than the inner diameter of the support frame 41. This design facilitates the formation of the exhaust channel 43, which in turn facilitates air convection between the support panel 42 and the support frame 41, thus facilitating heat dissipation.
[0033] Please refer to details. Figure 2 , Figure 3 , Figure 4 and Figure 5The connecting components include limiting posts 422 fixedly disposed on the lower end face of the support panel 42 and limiting retaining rings 412 fixedly disposed around the inner cavity of the support frame 41. The limiting retaining rings 412 are provided with limiting holes adapted to the limiting posts 422. The limiting retaining rings 412 are arranged circumferentially around the inner cavity of the support frame 41 and are located in the upper middle part of the inner cavity of the support frame 41. The limiting posts 422 and the limiting holes on the limiting retaining rings 412 are fixedly connected, so that the support frame 41 can be stably arranged around the support panel 42. The limiting retaining rings 412 are symmetrically distributed around the inner cavity of the support frame 41 and are located in the upper middle part, which ensures the relative position stability between the support panels 42, effectively prevents the support frame 41 from shifting or deflecting, and facilitates the transfer of heat to the vent holes 421 on the support panel 42 and the air convection through the exhaust channel 43, thereby improving the heat dissipation efficiency.
[0034] Please refer to details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The support components include a first guide rail 11, a second guide rail 12 mirror-imagely positioned relative to the first guide rail 11, mounting brackets 21 respectively positioned at both ends of the lower end face of the support frame 41, movable rollers 211 respectively positioned on the outer side of the mounting brackets 21, and a support bracket 22 positioned on the lower end face of each mounting bracket 21. The movable rollers 211 are adapted to the first guide rail 11 and the second guide rail 12, and the first guide rail 11 and the second guide rail 12 are configured in a "U" shape. By configuring the first guide rail 11 and the second guide rail 12 to be mirror-imagely positioned and with a "U" shape, the support components include a first guide rail 11, a second guide rail 12 mirror-imagely positioned relative to each other, and a second guide rail 12 with a "U" shape. The shape allows the movable rollers 211 to be adapted to it, achieving a concealed design and effectively avoiding the impact of high temperature environment on the movable rollers 211, thereby ensuring the stability of the support panel 42 when it moves. When the support panel 42 needs to be moved, the movable rollers 211 installed on the mounting brackets 21 at both ends of the support frame 41 cooperate with the first guide rail 11 and the second guide rail 12. The rollers move smoothly under the guidance of the first guide rail 11 and the second guide rail 12. The mounting brackets 21 are stably supported by the support brackets 22, so that the support panel 42 can move smoothly under the premise of ensuring safety.
[0035] Please refer to details. Figure 2 , Figure 3 , Figure 4 and Figure 5The drive assembly is located at the discharge end of the tunnel kiln. The drive assembly includes a rack 221 for connecting to the mounting frame 21, a drive gear 31 meshing with the rack 221, a rotating shaft 311 located between the first guide rail 11 and the second guide rail 12 and connected to the drive gear 31, and a drive motor 32 connected to the rotating shaft 311. A ball bearing is provided at the connection between the rotating shaft 311 and the first guide rail 11 and the second guide rail 12.
[0036] Please refer to details. Figure 2 The drive motor 32 is configured as a reversible motor. It is fixedly mounted on the outside of the first guide rail 11, and its output shaft is connected to the rotating shaft 311. The drive assembly is located at the discharge end of the tunnel kiln. Its working principle and technical effects are as follows: The drive assembly includes a rack 221, a drive gear 31, a rotating shaft 311, and a drive motor 32. The drive motor 32 is fixed on the outside of the first guide rail 11 and connected to the rotating shaft 311 via its output shaft, enabling reversible rotation. When the drive motor 32 starts and rotates, the rotating shaft 311 rotates accordingly, and the drive gear 31 rotates and meshes with the rack 221 installed between the first guide rail 11 and the second guide rail 12. This causes the mounting frame 21 to move along with the rack 221, thereby smoothly moving the support panel 42 laterally within the tunnel kiln, delivering the ceramic glaze to the sintering position. This achieves automated and efficient conveying, improving production efficiency and product quality.
[0037] In this embodiment, during use, when the drive motor 32 starts and rotates, the rotating shaft 311 rotates accordingly, and the drive gear 31 rotates and meshes with the rack 221 installed between the first guide rail 11 and the second guide rail 12, causing the mounting frame 21 to move along with the rack 221, thereby driving the support panel 42 to move smoothly laterally within the tunnel kiln, delivering the ceramic glaze to the sintering position, achieving automated and efficient conveying. When the support panel 42 needs to move, the moving rollers 211 installed on the mounting frames 21 at both ends of the support frame 41 engage with the first guide rail 11 and the second guide rail 12. With the cooperation of the two, the rollers move smoothly under the guidance of the first guide rail 11 and the second guide rail 12, while the mounting frame 21 is stably supported by the support frame 22, so that the support panel 42 can move smoothly under the premise of ensuring safety. The heat generated during the sintering process of the glaze is transferred to the heat dissipation holes 411 of the support frame 41 through the ventilation holes 421 on the support panel 42. The heat is discharged through the heat dissipation holes 411, and the air circulation between the support frame 41 and the support panel 42 is realized through the exhaust channel 43, so as to facilitate the timely discharge of heat during the sintering process and effectively ensure the quality of sintering of ceramic glaze.
