[0008] As a further optimization of this utility model, the bottom of the furnace body is provided with a second through groove located between the two first through grooves. The rotating structure includes a rotating rod that rotates through the first support plate and the second through groove and extends out of the furnace body. The top of the rotating rod is fixedly connected to a second support plate, the bottom of the first support plate is fixedly connected to a connecting rod, the bottom of the connecting rod is fixedly connected to a first connecting plate, and one end of the rotating rod is fixedly connected to a second servo motor that is fixedly connected to one side of the first connecting plate. The position of the second servo motor is fixed by the first connecting plate.

[0009] As a further optimization of this utility model, a positioning rod is fixedly connected to the upper surface of the second support plate, the positioning rod is inserted into a third support plate, a second support rod is fixedly connected to the upper surface of the third support plate, and a placement groove is fixedly connected to the top of the second support rod, so that the position of the placement groove is fixed by the second support rod.

[0010] As a further optimization of this utility model, a baffle is slidably connected inside the furnace body, and a protrusion is fixedly connected to the bottom of the baffle. A second connecting plate is fixedly connected to the top of the baffle by screws, and an electric push rod fixedly connected to the top of the furnace body is fixedly connected to the bottom of the second connecting plate.

[0020] like Figure 1 , Figure 3 and Figure 4As shown, a high-temperature sintering furnace with a preheating structure includes a furnace body 1. The furnace body 1 contains a preheating zone 12 and a sintering zone 13. Electric heating tubes 5 are fixedly connected to the inner walls of both the preheating zone 12 and the sintering zone 13. The electric heating tubes 5 are electrically connected to a controller. When an element enters the preheating zone 12, the electric heating tubes 5 in the preheating zone 12 are turned on, and the temperature of the preheating zone 12 is adjusted by the electric heating tubes 5. When an element enters the sintering zone 13, the electric heating tubes 5 in the preheating zone 12 are turned off, and the electric heating tubes 5 in the sintering zone 13 are turned on. A furnace door 2 is installed on one side of the furnace body 1 to prevent heat loss from the furnace body 1. An observation window 3 is provided on one side of the furnace door 2 to facilitate observation of the interior of the furnace body 1 by the operator. First support rods 4 are fixedly connected to the four corners of the bottom of the furnace body 1 to prevent direct contact between the furnace body 1 and the ground. A [furniture structure / mechanism] is provided on one side of the furnace body 1. The movable structure 6 includes two first through slots 602 located at the bottom of the furnace body 1. A threaded rod 603 is rotatably connected to the inner wall of one of the first through slots 602, and a threaded block is threadedly connected to the outer side of the threaded rod 603. A sliding rod 604 is fixedly connected to the inner wall of the other first through slot 602, and a slider is slidably connected to the outer side of the sliding rod 604. The first through slots 602 facilitate the movement of the threaded block and the slider. A first servo motor 601 is fixedly connected to one side of the threaded rod 603 and fixedly connected to the outer side of the furnace body 1. A first support plate 605 is fixedly connected to one side of the slider. The first servo motor 601 drives the threaded rod 603 to rotate. Both the slider and the threaded block are fixedly connected to the bottom of the first support plate 605. The movement of the slider and the threaded block drives the first support plate 605 to move. A rotating structure 7 is provided on the first support plate 605.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a baffle 8 is slidably connected inside the furnace body 1, dividing the interior of the furnace body 1 into a preheating zone 12 and a sintering zone 13. A protrusion 9 is fixedly connected to the bottom of the baffle 8, and a second connecting plate 10 is fixedly connected to the top of the baffle 8 by screws. An electric push rod 11, which is fixedly connected to the top of the furnace body 1, is fixedly connected to the bottom of the second connecting plate 10. The electric push rod 11 drives the baffle 8 to move up and down, and the protrusion 9 limits the baffle 8 to prevent it from directly detaching from the interior of the furnace body 1. A second through groove 606 is provided at the bottom of the furnace body 1 between two first through grooves 602. A rotating structure 7 is provided on the moving structure 6. The rotating structure 7 includes a rotating rod 701 that rotates through the first support plate 605 and the second through groove 606 and extends to the outside of the furnace body 1. The rotating rod 701 moves left and right through the second through groove 606. The top of the rotating rod 701 is fixedly connected to the second support plate 702, and the bottom of the first support plate 605... A connecting rod 707 is fixedly connected, and a first connecting plate 708 is fixedly connected to the bottom end of the connecting rod 707. A second servo motor 709, which is fixedly connected to one side of the first connecting plate 708, is fixedly connected to one end of a rotating rod 701. The first connecting plate 708 is supported by the connecting rod 707 at the bottom end of the first support plate 605, and the second servo motor 709 is supported by the first connecting plate 708. The second servo motor 709 drives the rotating rod 701 to rotate. A positioning rod 703 is fixedly connected to the upper surface of the second support plate 702. A third support plate 704 is inserted into the positioning rod 703. A positioning hole is provided at the bottom end of the third support plate 704. The positioning hole and the positioning rod 703 facilitate the disassembly of the third support plate 704. A second support rod 705 is fixedly connected to the upper surface of the third support plate 704. A placement groove 706 is fixedly connected to the top end of the second support rod 705, which facilitates placement.

[0022] It should be noted that in the use of this high-temperature sintering furnace with a preheating structure, the user opens the furnace door 2 and disassembles the third support plate 704 to facilitate the placement of the components to be sintered into the placement slot 706. After placement, the third support plate 704 is installed on the second support plate 702 through the positioning rod 703 and the positioning hole at the bottom of the third support plate 704, so that the placement slot 706 is placed in the preheating zone 12. After closing the furnace door 2, the interior of the furnace body 1 is heated by the electric heating tube 5. The second servo motor 709 drives the rotating rod 701, the second support plate 702, the third support plate 704, the second support rod 705, and the placement slot 706 to rotate within the preheating zone 12, so that the components in the placement slot 706 are placed in the preheating zone 12. The components can be heated evenly, and the material structure is made more compact. After preheating, the electric push rod 11 is used to push the second connecting plate 10 and the baffle 8 to rise. Then, the first servo motor 601 drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 drives the threaded block and the first support plate 605 to move. The first support plate 605 drives the slider to slide outside the slide rod 604. The threaded rod 603, the threaded block, the slide rod 604 and the slider slide in the first through groove 602 and the second through groove 606 to drive the placement groove 706 into the sintering zone 13. The second servo motor 709 drives the rotating rod 701 and the placement groove 706 to rotate, so that the components are heated evenly in the sintering zone 13.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
