[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1-Figure 8As shown, a denture glazing device proposed in Example 1 of the present invention includes a frame 1, a top plate 2 installed on the frame 1, and a conveying pump 4 and a material box 3 installed on the top plate 2. The feed pipe of the conveying pump 4 is connected to the material box 3. The material box 3 is used to hold glaze material. It also includes two conveyor belts 5 distributed in parallel on the frame 1 at intervals. The conveyor belts 5 perform annular circulation motion on the frame 1. Both ends of the frame 1 are rotated and penetrated by transmission rods 24. Both ends of the transmission rods 24 are fixed with transmission wheels 25. The four transmission wheels 25 are a group of two. The two conveyor belts 5 are respectively driven and wound on the corresponding two groups of transmission wheels 25. The end of one of the transmission rods 24 is connected to a power motor 26 arranged on the frame 1. The power motor 26 works , its output shaft drives the transmission rod 24 to rotate, thereby driving the two conveyor belts 5 to transmit synchronously in the same direction. The two conveyor belts 5 are provided with a support rod 6, and a positioning block 7 is installed on the support rod 6. The positioning block 7 is provided with three elastic clips 701 distributed in a circular array and protruding outward at the end. The denture is constrained on the positioning block 7 by the elastic clips 701. Preferably, it should be noted that a planting groove is provided at the bottom end of the denture, which is connected to other implants through the planting groove, so that the denture is implanted in the oral cavity. When the denture is fixed by glazing, the denture is placed above the positioning block 7, and several elastic clips 701 are made to correspond to the planting groove, and then the denture is pressed downward, so that several elastic clips 701 are placed by deformation and contraction. Into the planting groove, when the elastic clip 701 is placed in the planting groove, several elastic clips 701 will expand outward elastically, so as to constrain and fix the denture, and utilize the elastic deformation of the elastic clip 701 to cooperate with the outward protrusion of its end to elastically plug and clamp with the planting groove opened by the denture itself, so that the installation and fixation or release of the denture is more convenient. At the same time, after it is fixed, there is no obstruction on the outer peripheral side, which does not affect the glazing. A mounting frame 17 is installed in the frame 1, and a spray rod 18 is rotatably installed on the mounting frame 17. The spray rod 18 is L-shaped as a whole, and a plurality of nozzles 19 are distributed along its rod body, and several nozzles 19 are located on the inner side of the bend of the spray rod 18. A conveying pipe 20 is installed on the mounting frame 17. The delivery pipe 20 is connected with a branch pipe, and the branch pipe is connected to the spray rod 18 through a rotating joint. Preferably, the delivery pipe 20 is connected to the discharge pipe of the delivery pump 4. When the denture is glazed, the denture is constrained and fixed on the positioning block 7, and the conveyor belt 5 is used to transport the denture. When the denture is transported to the bottom of the spray rod 18 and aligned with the spray rod 18, the conveyor belt 5 stops transporting, and the spray rod 18 rotates so that it rotates around the denture. The delivery pump 4 transports the glaze in the material box 3 to the delivery pipe 20, and then transports it to the spray rod 18 through the branch pipe, and finally sprays it from a plurality of nozzles 19. Since the spray rod 18 rotates around the denture, the glaze is sprayed from the plurality of nozzles 19 to evenly glaze the surface of the denture;

[0030] In the present solution, a plurality of elastic clips 701 distributed in a ring shape are arranged on the positioning block 7, and the plurality of elastic clips 701 are elastically clamped with the implantation groove on the bottom side of the denture, so that the denture is not only convenient and quick to install or release, but also has no obstructions on the outer peripheral side after fixation, which will not cause obstruction to the glazing. At the same time, the spray rod 18 is L-shaped and is connected to a plurality of nozzles 19 in an array. When spraying glazing, the spray rod 18 rotates around the denture, and the glaze is evenly sprayed on the surface of the denture from the plurality of nozzles 19, so that there will be no dead angles in the spraying process of the denture, ensuring that the surface of the denture can be effectively covered and protected by the glaze, thereby improving practicality.

[0031] As a preferred embodiment, the conveyor belt 5 is provided with a mounting block 9, and both ends of the support rod 6 are provided with a positioning shaft 601, the positioning shaft 601 is rotatably connected to the mounting block 9, a rotating gear 12 is sleeved on the positioning shaft 601, and a rack 11 is installed in the frame 1. In actual use, in order to make the denture more suitable for the occlusion of the human oral cavity, the top of some dentures is not flat, but is constructed with grooves. During the spraying process, due to the structure of the groove, some excess glaze will slide to the lower part and gather at the bottom of the groove. When the denture is sprayed, the conveyor belt 5 drives the support rod 6 to transmit, and the rotating gear 12 and the rack 11 are engaged with teeth, so that the positioning shaft 601 drives the support rod 6 to rotate, thereby driving the denture to rotate with the support rod 6 as the center of the circle, so that during the rotation, the excess glaze gathered in the groove at the top of the denture is dumped out, so that the excess glaze will not gather and fill the groove, thereby retaining the groove at the top of the denture, which is in line with the actual structure of the tooth.

[0032] As a preferred embodiment, a cavity 602 is constructed in the positioning shaft 601, and a positioning pin 604 is installed in the cavity 602 through a connecting spring 603. One end of the positioning pin 604 passes through the positioning shaft 601 and is located on the outside. A positioning groove 13 for accommodating the positioning pin 604 is constructed on one side of the mounting block 9. Preferably, the notch of the positioning groove 13 is an arc-shaped expansion structure, and the end of the positioning pin 604 that is plugged into the positioning groove 13 is constructed as an arc-shaped head. In the initial state, under the elastic force of the connecting spring 603, the plug-in end of the positioning pin 604 is movably inserted into the positioning groove 13, thereby limiting the support rod 6 and preventing the support rod 6 from rotating, so that the denture is in a fixed position. Maintain a stable state during spray glazing. After the denture spray glazing is completed, the conveyor belt 5 continues to transmit and causes the rotating gear 12 and the rack 11 to engage with each other. Due to the arc-shaped expansion of the positioning groove 13 and the arc-shaped head structure of the positioning pin 604, the rotational torque generated when the rotating gear 12 and the rack 11 are engaged can force the positioning pin 604 to disengage from the positioning groove 13, thereby releasing the limit on the support rod 6. Preferably, the engagement stroke of the rotating gear 12 and the rack 11 can cause the support rod 6 to rotate 360 ​​degrees. When the rotating gear 12 and the rack 11 are released from engagement, the support rod 6 can be immediately limited and fixed, so that the denture remains in an upright upward state again.

[0033] As a preferred embodiment, the side of the frame 1 is equipped with rotating rods 14 distributed above and below the mounting block 9, and support is formed by the rotating rods 14 contacting the mounting block 9 and the conveyor belt 5. Since the conveyor belt 5 has a certain flexibility, by setting up two layers of rotating rods 14 distributed in the upper and lower layers, when the conveyor belt 5 is transmitted and the rotating gear 12 and the rack 11 are engaged with each other, the rotating rods 14 located in the upper layer rotate against the mounting block 9, and the rotating rods 14 located in the lower layer rotate against the conveyor belt 5, thereby ensuring that the rotating gear 12 and the rack 11 are effectively engaged with each other, and ensuring that the support rod 6 can drive the denture to rotate normally.

[0034] As a preferred embodiment, the mounting block 9 is detachably connected to the conveyor belt 5. By detachably connecting the mounting block 9 to the conveyor belt 5, modular transmission is achieved when spraying and glazing the dentures, that is, one support rod 6 is a module, and several dentures can be placed on one module, that is, the dentures are placed in batches on the same support rod 6, and the support rod 6 is placed on the conveyor belt 5 through the mounting block 9. When the spraying is completed, the support rod 6 is removed from the conveyor belt 5, thereby improving practicality.

[0035] As a preferred embodiment, the conveyor belt 5 is provided with a plurality of insertion holes 8 in an array along the belt surface direction, and the mounting block 9 is provided with an insertion block 10, which is inserted into the insertion hole 8. When transporting and placing, the two insertion blocks 10 on the two mounting blocks 9 are respectively inserted into the insertion holes 8 on the two conveyor belts 5, so that the two conveyor belts 5 support and transport the support rod 6. After spraying is completed, the support rod 6 can be removed and separated from the two conveyor belts 5, and installation or removal is relatively simple and convenient, thereby improving practicality.

[0036] As a preferred embodiment, a driving motor 23 is installed on the mounting frame 17, and a connecting gear 21 is installed on the driving motor 23 and the spray rod 18. A toothed belt 22 is provided on the meshing sleeve of the connecting gear 21. Figure 4 As shown, there are several spray rods 18, and connecting gears 21 are installed on several spray rods 18. When spraying, when a batch of dentures are located below the spray rods 18, and several dentures are respectively aligned with several spray rods 18, the driving motor 23 works, and its output shaft drives the connecting gear 21 to rotate. Under the transmission cooperation of several connecting gears 21 and toothed belts 22, several spray rods 18 are driven to rotate synchronously in the same direction, so that several dentures can be sprayed, so that when spraying and glazing a batch of dentures, effective and comprehensive spraying and glazing are carried out one by one, which not only ensures the spraying efficiency, but also improves the spraying quality.

[0037] As a preferred embodiment, the frame 1 is provided with a collecting trough 16 located below the mounting frame 17. When the denture is sprayed with glaze, it is inevitable that some glaze will be sprayed. At the same time, when the support rod 6 drives the denture to rotate and pours out the excess glaze in the groove at the top of the denture, the excess glaze will fall downward. The collecting trough 16 can be used to collect and store the fallen excess glaze, which is convenient for subsequent recycling or cleaning, thereby improving practicality.

[0038] As a preferred embodiment, a drying lamp 15 is installed in the frame 1. Preferably, the drying lamp 15 is located at the transmission output end of the frame 1. When the denture is glazed, it will be transmitted under the drying lamp 15. The drying lamp 15 bakes the denture, so that the glaze surface is quickly dried and shaped, so that assembly line processing is realized and glazing and drying are assembly lined, thereby improving practicality.

[0039] According to the working process of the present invention, when the denture is glazed, the elastic deformation of the elastic clamping strip 701 is used to cooperate with the outward protrusion of the end thereof, and the implantation groove provided in the denture itself is elastically plugged and clamped, so that the denture is constrained on the support rod 6. A plurality of dentures can be constrained and fixed on the same support rod 6, and then the support rod 6 is installed on the two conveyor belts 5 through the plug-in cooperation of the plug block 10 and the socket 8. The two conveyor belts 5 transmit the denture. When the denture is located below the spray rod 18, and a plurality of dentures are respectively aligned with a plurality of spray rods 18, at this time, the transmission of the conveyor belt 5 is stopped, the driving motor 23 is driven to work, and the connecting gear 21 and the toothed belt 2 are used to connect the two conveyor belts 5. 2, thereby driving a plurality of spray rods 18 to rotate synchronously in the same direction, so that even if batch spraying is performed, a plurality of spray rods 18 respectively perform single-to-single spraying on a plurality of dentures. At the same time, the spray rod 18 is L-shaped and has a plurality of nozzles 19 distributed in an array. When the spray rod 18 rotates around the denture, the glaze is sprayed from the plurality of nozzles 19 to fully cover the surface of the denture, avoiding the occurrence of spraying dead angles, thereby ensuring the spraying glazing effect. When the spraying is completed, the conveyor belt 5 continues to transmit, and the rotating gear 12 and the rack 11 are engaged with the teeth, so that the positioning shaft 601 drives the support rod 6 to rotate, thereby driving the denture to rotate with the support rod 6 is rotated as the center of the circle to dump out the excess glaze gathered in the groove at the top of the denture, so that the excess glaze will not gather and fill the groove, thereby retaining the groove at the top of the denture, which conforms to the actual structure of the tooth. Before rotating, the positioning pin 604 is plugged into and matched with the positioning groove 13 under the elastic resistance of the connecting spring 603, thereby limiting the support rod 6 to ensure that the support rod 6 will not rotate during the spraying process, ensuring that the denture surface is effectively glazed. During rotation, due to the arc-shaped expansion of the positioning groove 13 and the arc-shaped head structure of the positioning pin 604, the rotational torque generated when the rotating gear 12 and the rack 11 are engaged can force the positioning pin 604 to disengage from the positioning groove 13, thereby The limit on the support rod 6 is automatically released. When the rotation is completed, the positioning pin 604 is plugged into the positioning groove 13 under the elastic resistance of the connecting spring 603, thereby automatically limiting the support rod 6, so that the denture remains in an upright position, so that during the transmission process, it will pass under the drying lamp 15, and the drying lamp 15 will bake the denture. The baking temperature of the drying lamp 15 is used to quickly dry and shape the glaze surface of the denture, thereby completing the glazing process. The overall design is that the glazing is completed in an assembly line manner, so that when spraying and glazing are performed on batches of dentures, it is an effective and comprehensive one-to-one spraying and glazing, which not only ensures the spraying efficiency but also improves the spraying quality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
