[0031] Reference Figure 2 As a preferred embodiment, on the basis of the above-mentioned embodiment, further, the lower end of the input pipe 3 is provided with a plurality of input ends which are respectively connected to the hot melt chamber 2 .

[0032] A heating tube is provided in the hot melt chamber 2. The heating tube is an existing mechanism of the post-processing equipment. By energizing the heating tube, heat energy can be generated, and the denture below the hot melt chamber 2 can be baked. The input end can be the heat dissipation end of the hot melt chamber 2, which is convenient for the fan 5 to utilize the heat in the hot melt chamber to input it into the drying chamber 1 through the flowing air, thereby increasing the adequacy of the denture drying. The air in the hot melt chamber 2 is flowed through the input end to provide hot air for the drying chamber 1, which can also speed up the fluidity of the air in the hot melt chamber 2 and improve the baking efficiency of the denture. By using the input tube 3 and the input end at the top of the hot melt chamber 2, it is convenient to increase the heat energy output end on the hot melt chamber 2.

[0033] Reference Figure 2 As a preferred implementation, on the basis of the above-mentioned implementation, further, a common main pipe 4 is provided between the inlet pipe 3 and the fan 5 .

[0034] The main pipe is used to connect the fan 5 with the input pipe 3 to achieve air circulation in the input pipe 3.

Through the setting of the output pipe 6 and the output end, it is convenient to increase the opening at the top of the drying chamber 1, so as to facilitate the output of the conveyed hot air when the fan 5 is working, and then the denture can be dried with hot air.

[0036] Reference Figure 2 As a preferred implementation, on the basis of the above-mentioned method, further, the electric valve 7 is located between the output end and the fan 5, and the output pipe 6 is a switch structure of the output end of the fan 5. By energizing the output pipe 6, the switch state of the fan 5 can be flexibly controlled, which is convenient for controlling the switch of the hot air input in the fan 5, thereby increasing the flexibility of using the hot air in the drying chamber 1.

[0038] The use of the table-like structure of the supporting seat 12 and the upward position of the wide-mouth end thereof facilitate the placement of the denture in the supporting seat 12, and the use of multiple through openings 13 facilitates the outflow of liquid in the supporting seat 12. When the denture is used in the supporting seat 12, the supporting seat 12 and the reflective sheet 11 are used in combination to reflect the heat radiation generated during processing in the hot melt chamber 2, thereby increasing the heat radiation reflection rate and improving the baking efficiency of the denture.

[0039] Furthermore, the reflective sheet 11 and the supporting base 12 are both made of smooth metal materials.

[0040] The use of polished metal materials makes it easier for the reflective sheet 11 and the supporting seat 12 to utilize the smoothness of their surfaces to reflect the thermal radiation generated when the hot melt chamber 2 is working, thereby increasing the frequency of thermal radiation in the hot melt chamber 2 and increasing the baking rate of the denture. In addition, by using materials with a heat resistance higher than the working temperature of the hot melt chamber 2, it is convenient to place the seat 10 on the post-processing equipment for baking processing.

[0041] Reference Figure 5 As a preferred embodiment, on the basis of the above method, further, the clamping assembly 14 includes a support rod 15 arranged on the upper side of the bearing seat 12, a pressure rod 16 slidably arranged on the upper end of the support rod 15, a spring 17 arranged on the support rod 15 and located outside the proximal ends of the two pressure rods 16, and an edge plate 18 arranged at the same end of the spring 17 and the edge plate 18. The use of the clamping assembly 14 facilitates the addition of a denture clamping mechanism on the post-processing equipment. When the denture uses the clamping assembly 14, it will be arranged between the two clamping assemblies 14. By squeezing the edge plate 18 in the clamping assembly 14, the spring 17 can be compressed to clamp the denture between the two clamping assemblies 14.

A plurality of protrusions 21 are arranged on the opposite side of the two edge plates 18. By using the tightening bolts 19 at the upper and lower ends of the edge plate 18, it is convenient for the two tightening bolts 19 to tighten and limit the upper and lower ends of the denture respectively, and the edge ends of the two elastic parts 20 are retracted inward, and then the elastic part 20 of the elastic metal material is used to facilitate the horizontal tightening of the denture.

[0043] Specifically, when the utility model is used, the use technology of the existing input tube 3D resin denture post-processing equipment is first applied to drive the drying chamber 1, hot melt chamber 2, spray chamber and chain 9 on the equipment respectively, and then the tooth to be processed is placed between the two clamping assemblies 14 inside the hot melt chamber 2, and the denture is placed in the middle of the two edge plates 18 by stretching the pressure rod 16 at the proximal end of the two clamping assemblies 14, and then the pressure rod 16 is released. The spring 17 will drive the pressure rod 16 and the edge plate 18 to squeeze the denture, and the elastic part 20 of the elastic metal will be tightened on the horizontal outer side of the denture to achieve the limiting processing of the denture. When the upper and lower distances between the denture and the edge plate 18 are large, the tightening bolt 19 can be used. By tightening the tightening bolt 19 to the denture, the lower end of the tightening bolt 19 can be tightened on the denture, thereby increasing the stability of the denture processing and limiting and fixing the upper and lower sides of the denture. It is determined that when the post-processing equipment subsequently processes the denture, a driving mechanism will be used to drive the chain 9 to drive multiple placement seats 10 to rotate, so as to realize the position movement of the denture in the placement seat 10, and the baking, cleaning and drying operations will be carried out in sequence on the post-processing equipment. Moreover, by using the reflector 11 and the supporting seat 12 in the placement seat 10, it is convenient to suspend the denture in the placement seat 10, increase the fullness of the denture, and increase the processing rate and quality of the denture. Through the rotation of the fan 5, the input end can be used to mix part of the heat energy in the hot melt chamber 2 and the air outside the equipment, so that the mixture is hot air and passed into the branch pipe 8. Then, by opening the electric valve 7, the hot air in the output pipe 6 can be passed into the output end and enter the drying chamber 1, thereby increasing the hot air drying rate of the denture below the drying chamber 1, increasing the processing rate of the denture, and improving the processing quality of the post-processing equipment.
