Description

Technical Field

[0001] This utility model relates to the field of dental braces production, specifically to a heating structure for thermoforming dental braces. Background Technology

[0002] The diaphragms used in braces production are typically made of polymer materials, such as PETG or TPU. Heating is usually required to loosen the molecular structure of the diaphragm, making it soft and malleable, facilitating subsequent molding processes.

[0003] During heating, heating elements are usually used to radiate heat to the diaphragm. Typically, the heating element is placed on a mounting plate, and a heat insulation plate is placed around the heating element and fixed to the mounting plate. However, the heating element is often a single panel structure. In this case, the heating temperature of the center of the diaphragm is higher than that of the edge. This can easily cause the center of the diaphragm to soften more than the edge, resulting in products that do not meet the requirements.

[0004] Therefore, a heating structure for the thermoforming of dental braces is needed that can control the heating of the central part of the diaphragm. Utility Model Content

[0005] This utility model discloses a heating structure for thermoforming dental braces. By setting an independently temperature-controlled central heating block and at least four independently temperature-controlled peripheral heating blocks arranged around it, the heating effect on the center position of the dental brace diaphragm can be easily adjusted, thereby improving the product yield.

[0006] This utility model is achieved through the following technical solution.

[0007] A heating structure for thermoforming dental braces includes a mounting plate and a heating device fixed to one side of the mounting plate. The mounting plate is provided with a heat insulation plate around its periphery. The heating device includes an independently temperature-controlled central heating block and at least four independently temperature-controlled peripheral heating blocks arranged around it. The lower surfaces of the central heating block and the peripheral heating blocks are all located above the lower surface of the heat insulation plate. Each of the central heating block and each peripheral heating block is provided with an independent electrical wire, which extends through the mounting plate to an external power interface.

[0008] Furthermore, the central heating block and the peripheral heating block are ceramic heating blocks.

[0009] Furthermore, it also includes a plurality of fixing brackets disposed on the mounting plate, each fixing bracket including a fixing plate and a connecting foot extending from the periphery of the fixing plate, the connecting foot being fixed to the mounting plate by bolts.

[0010] Furthermore, the fixing plate is provided with a U-shaped slot, and the central heating block and the peripheral heating block are provided with sliding grooves that cooperate with the U-shaped slot.

[0011] Furthermore, the mounting plate has a strip-shaped hole through which the electrical wire passes.

[0012] Furthermore, the heat insulation plate is provided with a mounting groove that matches the outer contour of the mounting plate, and the mounting plate is fixed in the mounting groove by bolts.

[0013] Furthermore, the distance between the lower surface of the central heating block and the peripheral heating block and the lower surface of the heat insulation plate in the vertical direction is 20~50mm.

[0014] Compared with the prior art, this utility model has the following advantages.

[0015] This patent designs the heating device as a central heating block with independent temperature control and at least four peripheral heating blocks with independent temperature control surrounding it. This allows for independent temperature control of the ceramic heating blocks' heating effect, preventing the diaphragm's central heating temperature from becoming too high. To facilitate the fixing of the heating device, multiple fixing brackets are provided. These brackets are inserted into U-shaped slots on the fixing plate via integrally formed grooves on the ceramic heating blocks, effectively avoiding the problem of compression and cracking that can occur with direct bolt fixing. Furthermore, to facilitate the installation of the heat insulation plate, mounting grooves matching the outer contour of the mounting plate are provided on the heat insulation plate. Bolts are inserted laterally into the mounting grooves to thread the mounting plate, making the installation structure more convenient. Attached Figure Description

[0022] like Figures 1-5 As shown,

[0023] A heating structure for thermoforming braces includes a mounting plate 10 and a heating device 20 fixed to one side of the mounting plate 10. The mounting plate 10 is provided with a heat insulation plate 30 around its periphery. The heating device 20 includes an independently temperature-controlled central heating block 201 and at least four independently temperature-controlled peripheral heating blocks 202 arranged around it. Preferably, an independently temperature-controlled central heating block 201 and four independently temperature-controlled peripheral heating blocks are provided around it, which can effectively achieve the original heating area.

The lower surfaces of the central heating block 201 and the peripheral heating block 202 are both located above the lower surface of the heat insulation plate 30. The vertical distance between the lower surfaces of the central heating block 201 and the peripheral heating block 202 and the lower surface of the heat insulation plate 30 is 20~50mm, preferably 30mm.

[0025] In addition, for convenient temperature control, the central heating block 201 and each peripheral heating block 202 are provided with independent electrical wires. The mounting plate 10 has strip holes 102 for the electrical wires to pass through. The electrical wires extend through the mounting plate 10 to the external power interface for connecting to their respective temperature control modules. The number of strip holes 102 is the same as the sum of the number of the central heating block 201 and the peripheral heating blocks 202.

[0026] A further embodiment is that, to facilitate the installation of the heating device 20, the heating structure also includes a plurality of fixed brackets 101 disposed on the mounting plate 10. Each fixed bracket 101 includes a fixed plate 1011 and a connecting foot 1012 extending from the periphery of the fixed plate 1011. The connecting foot 1012 is fixed to the mounting plate 10 by bolts. The fixed plate 1011 is provided with a U-shaped slot 10111. The central heating block 201 and the peripheral heating block 202 are provided with sliding grooves that cooperate with the U-shaped slot 10111. The central heating block 201 and the peripheral heating block 202 are engaged with the U-shaped slot 10111 through the sliding grooves, which can be stably fixed on the mounting plate and can avoid damage caused by direct bolt connection.

[0027] A further solution is that, in order to facilitate the installation of the heat insulation plate 30, the heat insulation plate 30 is provided with a mounting groove 301 that matches the outer contour of the mounting plate 10. A through hole is provided on the side of the mounting groove 301, and the mounting plate 10 is fixed in the mounting groove 301 by bolts passing through the through hole and threaded connection.
