Description

Technical Field

[0001] The invention relates to a ceramic setter plate structure capable of preventing fracture, and belongs to the technical field of ceramic setter plates. Background Art

[0002] Ceramic setter is a tool used in ceramic kilns, mainly used to carry and transport the fired ceramic blanks; it can increase the heat conduction speed, make the fired products evenly heated, effectively reduce energy consumption and speed up the firing speed, and increase production. At the same time, ceramic setter can also make the products fired in the same kiln have no obvious color difference and small deformation, thereby improving product quality. In addition, ceramic setter also has the function of increasing the strength of the setter and reducing the breakage rate. Ceramic setter is widely used in ultra-high temperature electric kiln and electric furnace firing, industrial ceramics, electronic components manufacturing and other fields.

[0003] When in use, the ceramic support plate is sent into the kiln together with the ceramic blank to be fired at high temperature. After firing, it is removed from the kiln for cooling. The existing ceramic support plate is a large flat plate structure. After repeated use, due to frequent thermal expansion and contraction of the ceramic support plate, internal stress concentration will cause it to break and be damaged, making it impossible to continue to use. Therefore, it needs to be replaced frequently, which greatly increases the production cost of the ceramic. Summary of the invention

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a ceramic support plate structure that prevents breakage, which can effectively avoid the breakage and damage of the ceramic support plate caused by thermal expansion and contraction during use, extend the service life of the ceramic support plate, and reduce the production cost of ceramics.

[0006] The technical solution of the present invention is to provide a ceramic supporting plate structure that prevents breakage, wherein the supporting plate of the ceramic blank is split into a double-end connected supporting plate and a single-end connected supporting plate. When thermal expansion and contraction occur, the supporting connecting plates at both ends of the double-end connected supporting plate change position with the expansion and contraction of the double-end connected supporting plate, while the connecting end of the single-end connected supporting plate changes position with the supporting connecting plate connected thereto, and the other end can float at will, so as to facilitate the release of stress in the ceramic supporting plate and prevent breakage and damage.

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

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

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

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

[0012] Preferably, the double-end connection bearing plate, the single-end connection bearing plate and the supporting connection plate are one of a solid plate, a circular hole plate, a square hole plate, a triangular hole plate, a diamond hole plate, a hexagonal hole plate and an octagonal hole plate.

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

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

[0016] Preferably, the connection method between the double-end connection load-bearing plate and the supporting connection plate, and the single-end connection load-bearing plate and the supporting connection plate includes but is not limited to any one of adhesive connection, bolt connection, pin connection, and welding.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The ceramic supporting plate structure for preventing fracture described in the present invention comprises a supporting plate including a double-end connected supporting plate and a single-end connected supporting plate.
