Description

Technical Field

[0001] This utility model relates to a ceramic firing plate structure that prevents breakage, and belongs to the field of ceramic firing plate technology. Background Technology

[0002] A ceramic firing plate is a tool used in ceramic kilns, primarily for supporting and transporting the ceramic blanks to be fired. It improves heat transfer speed, ensuring uniform heating of the fired products, effectively reducing energy consumption and accelerating firing, thus increasing output. Simultaneously, ceramic firing plates ensure that products fired in the same kiln exhibit minimal color variation and deformation, thereby improving product quality. Furthermore, ceramic firing plates also enhance the strength of the firing plate itself, reducing breakage rates. Ceramic firing plates are widely used in ultra-high temperature electric kilns, industrial ceramics, and electronic component manufacturing, among other fields.

[0003] When ceramic firing plates are used, they are sent into the kiln along with the ceramic blanks to be fired at high temperatures. After firing, they are removed from the kiln for cooling. The existing ceramic firing plates are large flat plates. After repeated use, due to the frequent thermal expansion and contraction of the ceramic firing plates, the internal stress is concentrated, which can lead to breakage and damage, making them unusable. Therefore, they need to be replaced frequently, which greatly increases the production cost of ceramics. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a ceramic firing plate structure that prevents breakage, which can effectively avoid the breakage and damage caused by thermal expansion and contraction during the use of ceramic firing plates, extend the service life of ceramic firing plates, and reduce the production cost of ceramics.

[0005] The ceramic firing plate structure for preventing breakage described in this utility model includes a support plate and a supporting connecting plate connected to the end of the support plate. The support plate is used to support the ceramic blank. The support plate includes a double-end connected support plate and a single-end connected support plate. The two ends of the double-end connected support plate are fixedly connected to the supporting connecting plate, and one end of the single-end connected support plate is fixedly connected to the supporting connecting plate.

[0006] The technical solution of this utility model is to provide a ceramic firing plate structure to prevent breakage. The support plate of the ceramic body is divided into a double-end connected support plate and a single-end connected support plate. When thermal expansion and contraction occur, the supporting connecting plates at both ends of the double-end connected support plate change position with the expansion and contraction of the double-end connected support plate, while the connecting end of the single-end connected support plate changes position with the supporting connecting plate connected to it, and the other end can float freely, so as to facilitate the release of internal stress in the ceramic firing plate and prevent breakage and damage.

[0007] Furthermore, the other end of the single-end connecting bearing plate is not connected to the supporting connecting plate or is point-bonded, and the connection strength of the point bond is much lower than that of the fixed connecting end.

[0009] Preferably, the number of double-ended connecting bearing plates is at least one, and the number of single-ended connecting bearing plates is at least one.

[0010] Preferably, the number of supporting connecting plates is two, which are connected in parallel to both ends of the double-end connecting bearing plate.

[0011] Furthermore, when there are two or more single-end connecting bearing plates, the single-end connecting bearing plates are distributed on both sides of the double-end connecting bearing plates; the fixed connection ends of each single-end connecting bearing plate and the two supporting connecting plates are staggered.

[0012] Preferably, the double-ended connecting bearing plate, the single-ended connecting bearing plate, and the supporting connecting plate are one of the following: solid plate, round hole plate, square hole plate, triangular hole plate, rhombic hole plate, hexagonal hole plate, and octagonal hole plate.

[0013] Preferably, the double-ended connecting bearing plate, the single-ended connecting bearing plate, and the supporting connecting plate have through holes, and the cross-sectional shape of the through holes includes, but is not limited to, any one of the following: circular, square, triangular, rhomboid, hexagonal, and octagonal.

[0014] Furthermore, the number of through holes in the double-ended connecting bearing plate, the single-ended connecting bearing plate, and the supporting connecting plate is greater than or equal to one, and the through holes are evenly distributed.

[0015] Preferably, the double-ended connecting support plate is provided with a positioning boss A, which is located on both sides of the contact surface between the double-ended connecting support plate and the supporting connecting plate; the single-ended connecting support plate is provided with a positioning boss B, which is located at the fixed connection end between the single-ended connecting support plate and the supporting connecting plate; the supporting connecting plate is provided with a positioning groove that matches the positioning boss A and the positioning boss B.

[0016] Preferably, the connection methods of the double-ended connecting bearing plate and the supporting connecting plate, and the single-ended connecting bearing plate and the supporting connecting plate, include, but are not limited to, any one of adhesive connection, bolt connection, pin connection, and welding.

[0017] The advantages of this utility model compared with the prior art are:

[0018] The ceramic firing plate structure for preventing breakage described in this utility model includes a double-ended connecting plate and a single-ended connecting plate. When thermal expansion and contraction occur, the supporting connecting plates at both ends of the double-ended connecting plate change position with the expansion and contraction of the double-ended connecting plate, while the connecting end of the single-ended connecting plate changes position with the supporting connecting plate it is connected to, and the other end can float freely, so as to facilitate the release of internal stress in the ceramic firing plate and prevent breakage and damage. This utility model extends the service life of the ceramic firing plate and reduces the production cost of ceramics. Attached Figure Description
