[0002] Alumina fiber is a polycrystalline inorganic fiber primarily composed of aluminum oxide (Al2O3), with some also containing small amounts of metal oxides such as SiO2 and B2O3. Alumina fiber exhibits superior heat resistance to other fibers, capable of withstanding ultra-high temperatures of 1450°C to 1600°C. It possesses high tensile strength, a good elastic modulus, excellent electrical insulation properties, and excellent chemical stability. It also exhibits low thermal conductivity and coefficient of thermal expansion, as well as excellent thermal shock resistance. Alumina continuous fibers are often used as structural reinforcements to prepare composite materials. Composite materials, as high-temperature thermal insulation materials, have found widespread application in weaponry, aviation, aerospace, and automotive applications.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Reference Figure 1-Figure 5 A sintering and winding device for alumina fiber includes a cylindrical wall 1, a mounting ring 2 is installed on the end side of the cylindrical wall 1 for loading and unloading, and a cylindrical tube 3 is clamped on the side wall of the mounting ring 2. A sintering and winding device for alumina fiber also includes a fastening component and a disassembly component.

[0044] The fastening assembly is used to fasten the mounting ring 2 and the cylindrical wall 1. The fastening assembly includes a groove 21, a fixing rod 22, a sleeve 23, a screw 24, a nut 25, a recess 201 and a clamping groove 202. The grooves 21 are provided on opposite sides of the mounting ring 2. The fixing rod 22 is fixed in the groove 21. The sleeve 23 is rotatably sleeved on the fixing rod 22. The sleeve 23 can rotate freely on the fixing rod 22 to facilitate adjustment of the position of the screw 24 so that it can be accurately aligned with the recess 201 and inserted therein. The screw 24 is fixed on the top surface of the sleeve 23, and the nut 25 is threadedly sleeved on the screw 24. The recess 201 is symmetrically provided on opposite sides of the mounting ring 2. The screw 24 is placed in the recess 201 for movement. The clamping groove 202 is provided on the top surface of the mounting ring 2. The shape of the nut 25 matches the shape of the clamping groove 202. After the nut 25 is tightened, it can be completely embedded in the clamping groove 202 to ensure that the nut 25 does not protrude from the surface of the mounting ring 2 to avoid interference with the operation of the device.

[0045] The disassembly and assembly components are used to disassemble and assemble the cylindrical tube 3. The disassembly and assembly components include an embedded rod 31, a slot 32, an embedded hole 33, an insertion rod 34, a spring 35, a pressing plate 36, a through hole 37, a screw hole 38 and a screw 39. The embedded rod 31 is fixed on opposite sides of the top surface of the cylindrical tube 3. The slot 32 is provided in the embedded rod 31. The embedded hole 33 is provided on opposite sides of the mounting ring 2. The embedded rod 31 is plugged into the embedded hole 33. The insertion rod 34 is slidably connected to the mounting ring 2. The insertion rod 34 is plugged into the slot 32. The insertion rod 34 can slide on the mounting ring 2 in a direction perpendicular to the embedded rod 31, and the sliding is smooth to ensure that the pressing plate 36 can be pressed normally to separate the insertion rod 34 from the slot 32. The spring 35 is sleeved on the insertion rod 34. The pressing plate 36 is fixed to the end side of the insertion rod 34, and the two ends of the spring 35 are fixedly connected to the side wall of the pressing plate 36 and the inner wall of the mounting ring 2 respectively. When the spring 35 is in a natural state, the end of the insertion rod 34 is inserted into the slot 32, locking the embedded rod 31 in the embedded hole 33, thereby realizing stable installation of the cylindrical tube 3 on the mounting ring 2. A through hole 37 is opened on the pressing plate 36, and screw holes 38 are opened on the inner walls of the mounting ring 2 on both sides. The screw 39 is threadedly connected in the screw hole 38, and the screw 39 is plugged into the through hole 37. The screw 39 can be inserted into the screw hole 38 through the through hole 37. When the screw 39 is tightened, the movement of the pressing plate 36 can be further restricted, thereby ensuring that the insertion rod 34 will not accidentally disengage from the slot 32, thereby improving the stability of the installation of the cylindrical tube 3.

[0046] The functional principle of this utility model can be explained through the following operation modes:

[0047] When installing and sintering the device, first install the mounting ring 2 and the cylindrical tube 3. During installation, align the embedded rod 31 on the cylindrical tube 3 with the embedded hole 33 on the mounting ring 2 and insert it. During the insertion process, the embedded rod 31 touches the insertion rod 34, and the insertion rod 34 is forced to slide in the mounting ring 2. As the embedded rod 31 continues to slide, when the insertion rod 34 is completely embedded therein, the insertion rod 34 is at the same horizontal plane as the slot 32, and the elastic performance of the spring 35 is used to make the insertion rod 34 automatically inserted into the slot 32 of the embedded rod 31, and then the screw 39 is inserted into the through hole 37 on the pressing plate 36 and The screw hole 38 is inserted and rotated after insertion so that the screw 39 is fixed thereto and the cylindrical tube 3 is locked on the mounting ring 2. Then the mounting ring 2 with the cylindrical tube 3 installed is aligned with the cylindrical wall 1 and inserted into it so that the bottom surface of the mounting ring 2 is in contact with the top surface of the cylindrical wall 1. Then the sleeve 23 is rotated so that the screw 24 passes through the recess 201 and enters the interior of the mounting ring 2. Then the nut 25 is screwed onto the screw 24 and tightened until the nut 25 is completely embedded in the snap-fit ​​groove 202. In this way, the mounting ring 2 and the cylindrical wall 1 are firmly connected to ensure that the two will not loosen during operation of the device.

[0048] When the cylindrical tube 3 needs to be disassembled, the screw 39 is rotated to disengage the screw hole 38 to release the limit on the insertion rod 34, and then the insertion rod 34 is pulled out to slide outward to disengage the slot 32 on the embedded rod 31, and then the cylindrical wall 1 is pulled out to disengage the embedded rod 31 on its end side from the embedded groove. At this time, the cylindrical tube 3 can be removed from the mounting ring 2 and can be quickly disassembled and replaced.

[0049] When disassembling the mounting ring 2 and the cylindrical tube 3, the rotating knob moves upward along the thread diameter of the screw 24 to disengage from the engaging groove 202, and then the screw 24 is rotated to drive the sleeve 23 to rotate so that it disengages from the recess 201 and releases the limit of the two, so that the cylindrical tube 3 can be quickly disassembled, thereby completing the disassembly operation.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
