Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 —7. A sintering furnace for denture production, comprising a conveying device 200, a sintering mechanism, and a crucible member 300, wherein the sintering mechanism comprises a mechanism housing 100, a lifting and lowering motion module 101, and a clamping module 102. A sintering zone 103 is provided on the mechanism housing 100. A sintering chamber 104 is provided on the mechanism housing 100 at the upper part of the sintering zone 103. A heating component is fixedly connected in the sintering chamber 104. The heating component is used to heat the sintering chamber 104, and any component with a heating effect can be selected. In addition, the conveying device 200 passes through the sintering zone 103, that is, the conveying device 200 comprises a conveyor belt 201 and a conveying drive motor 202 for driving the conveyor belt 201. The conveyor to be transported passes through the sintering zone 103. A plurality of groups of crucible members 300 can be placed on the conveyor belt 201, so that the crucible members 300 are transported by the conveying device 200;

[0025] Furthermore, a lifting motion module 101 is also provided on the mechanism housing 100, and the lifting motion module 101 includes a lifting platform 105, a lifting screw 106, a sliding column 107 and a lifting drive motor 108, that is, a first mounting groove 109 is provided on the mechanism housing 100, a sliding column 107 is fixedly connected in the first mounting groove 109, a lifting platform 105 is slidably connected on the sliding column 107, a lifting screw 106 is threadedly connected on the lifting platform 105, a lifting drive motor 108 is fixedly connected in the first mounting groove 109, and the lifting drive motor 108 is power-connected to the lifting screw 106, so that when the lifting drive motor 108 drives the lifting screw 106 to rotate, the lifting platform 105 can perform a linear lifting motion on the sliding column 107;

[0026] Furthermore, the lifting platform 105 is also fixedly connected with a clamping module 102 through a connecting piece 119. The clamping module 102 is located in the sintering area 103. The clamping module 102 is mainly used to clamp the conveyed crucible 300. In addition, a lifting slot 110 is provided in communication with the first mounting slot 109 and the sintering area 103. The connecting piece 119 passes through the lifting slot 110, so that when the lifting platform 105 performs a linear motion, the clamping module 102 can be driven to perform a lifting motion. At this time, the connecting piece 119 moves in the lifting slot 110.

[0027] More specifically, the crucible member 300 includes a clamping bottom plate 301 and a crucible body 302 fixedly connected to the upper portion of the clamping bottom plate 301. A circular inlet is provided at the bottom of the sintering chamber 104. The diameter of the clamping bottom plate 301 is larger than the diameter of the clamping bottom plate 301. Thus, the clamping bottom plate 301 of the crucible member 300 can be clamped by the clamping module 102. Then, under the action of the lifting and lowering module 101, the crucible body 302 enters the sintering chamber 104, and the clamping bottom plate 301 can seal the circular inlet.

[0028] In addition, in the embodiment, the clamping module 102 includes a clamping shell 112, a clamping arm 113, a first lead screw 114, a second lead screw 115 and a clamping drive motor 116. The clamping shell 112 is fixedly connected to the connecting member 119. Two groups of moving platforms are slidably connected in the clamping shell 112, one group of moving platforms is threadedly connected to the first lead screw 114, and the other group of moving platforms is threadedly connected to the second lead screw 115. Each group of moving platforms is fixedly connected to the clamping arm 113. The clamping shell 112 is matched with each group of moving platforms and is provided with a moving opening 120. The clamping arm 113 passes through the moving opening 120, and the clamping drive motor 116 is also fixedly connected in the clamping shell 112. The clamping drive motor 116 is power-connected to the first lead screw 114 and the second lead screw 115. In this way, when the clamping drive motor 116 drives the first When the lead screw 114 and the second lead screw 115 rotate synchronously, the two groups of moving tables can move away from or towards each other, so that the two groups of clamping arms 113 can move closer to or away from each other. When the two groups of clamping arms 113 move closer to each other, they can clamp the clamping chassis 301, and when the two groups of clamping arms 113 move away from each other, they can release the clamping chassis 301. In addition, the clamping shell 112 is fixedly connected to the limiting column 117, and the moving table is slidably connected to the limiting column 117, so that the moving table is slidably connected in the clamping shell 112 to meet the working requirements of the lead screw. The above-mentioned clamping arm 113 is also provided with a clamping arc groove 118. The clamping arc grooves 118 of the two groups of clamping arms 113 are mirror-imaged. Through the setting of the clamping arc groove 118, the clamping effect of the clamping arm 113 on the clamping chassis 301 can be improved to ensure stable clamping.

[0029] In order to improve the overall automation effect, a detection sensor 400 is fixedly connected to the clamping shell 112 corresponding to the sintering area 103. The detection sensor 400 is used to detect the position of the crucible 300 transported on the conveyor belt 201, and a controller is fixedly connected in the mechanism shell 100. The controller is a PLC controller. A control module 500 is also fixedly connected to the mechanism shell 100. The control module 500 includes a display screen and control buttons. The display screen is used to display all signals, such as sintering temperature, time, control information, working status, etc. A temperature sensor is also fixedly connected in the sintering chamber 104. The temperature in the sintering chamber 104 is detected by the temperature sensor. The above-mentioned detection sensor 400, control module 500, temperature sensor, heating component, lifting drive motor 108, clamping drive motor 116 and conveying drive motor 202 are all connected to the controller signal. The specific connection method is the existing technology, so it is not repeated here, mainly to achieve the following automation effects:

[0030] The plurality of groups of crucibles 300 are transported by the conveying device 200, and the crucible body 302 of each group of crucibles 300 contains the artificial teeth to be sintered. After a group of crucibles 300 is transported to the sintering area 103 by the conveying device 200, the detection sensor 400 detects the crucibles 300, and the conveying device 200 stops working. Then, the lifting and lowering movement module 101 works (the controller controls the lifting and lowering drive motor 108), so that the clamping module 102 descends to the bottom, and the crucibles 300 are clamped by the clamping module 102 (the controller controls the clamping drive motor 116), and then the crucibles 300 are clamped by the clamping module 102. The lifting and lowering module 101 drives the clamping module 102 and the crucible 300 clamped therein to enter the sintering chamber 104, and heats the denture by the heating component to sinter it. When the sintering time is reached, the lifting and lowering module 101 drives the clamping module 102 and the crucible 300 clamped therein to descend to the conveying device 200, and then the clamping module 102 releases the crucible 300. Then, the lifting and lowering module 101 drives the clamping module 102 to rise, and the conveying device 200 conveys the crucible 300 out. When the next group of crucibles 300 is detected by the detection sensor 400, the above steps are repeated.

[0031] The sintering temperature and sintering time can be set by the control buttons in the control module 500, and the working speed of the device can also be set. The specific settings can be implemented through programming according to actual needs.
