Description

Technical Field

[0001] This utility model relates to the field of continuous alumina fiber winding technology, specifically to an alumina continuous fiber winding and sintering device. Background Technology

[0002] Alumina continuous fiber is a fibrous material composed of aluminum atoms. It has excellent high-temperature heat resistance, corrosion resistance, light weight, high strength and good electrical conductivity. In the preparation process of alumina continuous fiber, the alumina continuous fiber is wound into a specific shape by a winding device, and then the alumina continuous fiber wound into a specific shape is sintered at high temperature to prepare high-performance refractory materials and composite materials.

[0003] Because alumina fibers will produce a certain degree of expansion and contraction during the sintering process, the existing winding devices are mostly single winding roller structures to wind the continuous alumina fibers to be sintered. However, the single winding roller structure cannot well adapt to the tension generated by the continuous alumina fibers during the sintering process in the sintering furnace, which makes the alumina fibers prone to breakage during the sintering process, greatly increasing the sintering cost of alumina fibers and making them impractical. Utility Model Content

[0004] The purpose of this invention is to provide an alumina continuous fiber winding and sintering device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A continuous alumina fiber winding and sintering apparatus includes a sintering furnace, a support frame, and a base plate. The base plate is placed in front of the sintering furnace. The support frame is provided on the upper surface of the base plate. A winding assembly is provided on the upper end of the support frame. The winding assembly is used to wind the continuous alumina fiber to be sintered. An elastic support assembly is provided inside the winding assembly. The elastic support assembly is used to provide elastic support for the winding assembly.

[0007] Preferably, the winding assembly includes a support shaft, a follower roller, a support cylinder, a winding plate, and a support rod. The support shaft is placed on the upper end of the support frame. The follower roller is arranged on the annular side of the support shaft. The support cylinder is symmetrically arranged on both the upper and lower ends and the left and right sides of the annular side of the follower roller. The support rod is arranged on the upper end of the support cylinder, and the winding plate is arranged on the upper end of the support rod.

[0008] Preferably, the elastic support assembly includes an inner liner, a high-temperature resistant spring, a limiting cover, a support block, and a limiting cavity. The limiting cover is installed on the upper end face of the support cylinder, a limiting cavity is formed inside the support cylinder, a high-temperature resistant spring is installed inside the limiting cavity, an inner liner is installed on the lower side inside the limiting cavity, and a support block is provided at the bottom of the support rod.

[0009] Preferably, the inner liner is symmetrically provided with extension screws on its left and right ends, a positioning nut is installed on the annular side of the extension screw, and a grip handle is provided on the left end face of the extension screw.

[0010] Preferably, the support cylinder has symmetrical limit grooves on both sides of its annular side, and the support cylinder has height scale lines on its annular side.

[0011] Preferably, the upper surface of the winding plate is provided with a side baffle, and the winding plate is arc-shaped.

[0012] Preferably, an insertion groove is provided at the middle position of the front end face of the support shaft, an insertion rod is inserted into the insertion groove, and a hand dial is provided at the front end of the insertion rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the support shaft, the support shaft can drive the winding plate to rotate together through the follower roller, support cylinder and support rod to wind the continuous alumina fiber to be sintered. The side baffle can also prevent the continuous alumina fiber from slipping outward during the winding process, so that the workers can wind the continuous alumina fiber to be sintered conveniently and effortlessly.

[0015] 2. By loosening the positioning nut, the inner liner can be moved by holding the handle and extension screw. During this process, as the inner liner moves outward, it gradually applies pressure to the high-temperature spring, which in turn increases the pressure of the high-temperature spring on the support block. At this time, the support force of the support rod on the winding plate will also increase, and vice versa. This allows the operator to adjust the strength of the winding plate's support force as needed, so that the winding plate can adapt to the tension generated by the alumina continuous fiber during the sintering process in the sintering furnace, thereby reducing fiber breakage and ensuring the sintering quality of the alumina continuous fiber. This method is highly practical. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] Example 1:

[0025] A continuous alumina fiber winding and sintering apparatus includes a sintering furnace 1, a support frame 2, and a base plate 3. The base plate 3 is placed in front of the sintering furnace 1, and the support frame 2 is provided on the upper surface of the base plate 3. The base plate 3 and the support frame 2 are an integral structure. The base plate 3 can increase the support area at the bottom of the support frame 2 so that the support frame 2 can stably support the winding assembly 4.

[0026] The upper end of the support frame 2 is provided with a winding assembly 4, which is used to wind the continuous alumina fiber to be sintered. The winding assembly 4 is provided with an elastic support assembly 5, which is used to provide elastic support for the winding assembly 4, so that the winding assembly 4 can adapt to the tension generated by the continuous alumina fiber during the sintering process in the sintering furnace 1, thereby reducing fiber breakage and ensuring the sintering quality of the continuous alumina fiber. Since the detailed internal structure and working principle of the sintering furnace 1 are relatively mature technologies in the prior art, they will not be described in detail here.

[0027] The winding assembly 4 includes a support shaft 41, a follower roller 42, a support cylinder 46, a winding plate 47, and a support rod 49. The support shaft 41 is placed on the upper end of the support frame 2. The support shaft 41 and the follower roller 42 are an integral structure. The support shaft 41 can support the follower roller 42. The follower roller 42 is arranged on the annular side of the support shaft 41. The follower roller 42 is connected to the support cylinder 46 by welding. The follower roller 42 can support the support cylinder 46. The support cylinder 46 is symmetrically arranged on the upper and lower ends and the left and right sides of the annular side of the follower roller 42. The support cylinder 46 can provide limiting support for the elastic support assembly 5. The support rod 49 is arranged on the upper end of the support cylinder 46. The support rod 49 is connected to the winding plate 47 and the support block 58 by welding. The support rod 49 can support the winding plate 47. The support rod 49 is rectangular in shape. The rectangular support rod 49 will not rotate during the telescopic use.

[0028] A winding plate 47 is provided at the upper end of the support rod 49. The winding plate 47 is arc-shaped and can wind up the continuous alumina fibers to be sintered. A side baffle 48 is provided on the upper surface of the winding plate 47. The side baffle 48 is connected to the winding plate 47 by welding. The side baffle 48 can limit and block the continuous alumina fibers wound on the winding plate 47, preventing the continuous alumina fibers from slipping off during the winding process. Furthermore, an insertion groove 43 is provided at the middle position of the front end face of the support shaft 41. The insertion groove 43 matches the insertion rod 44. The insertion groove 43 facilitates the insertion of the insertion rod 44 into the front end of the support shaft 41. The insertion rod 44 is inserted inside the insertion groove 43. A hand dial 45 is provided at the front end of the insertion rod 44. The hand dial 45 is connected to the insertion rod 44 by welding. The hand dial 45 allows the operator to rotate the insertion rod 44 by hand so that the insertion rod 44 can drive the support shaft 41 to rotate.

[0029] Example 2:

[0030] Based on Embodiment 1, in this embodiment, by loosening the positioning nut 55, the inner liner 51 can be displaced by holding the handle 56 and the extension screw 511. During this process, when the inner liner 51 moves outward, it gradually applies a compressive force to the high-temperature spring 52, thereby gradually increasing the compressive force of the high-temperature spring 52 on the support block 58. At this time, the support force of the support rod 49 on the winding plate 47 will also increase accordingly. Conversely, the support force of the support rod 49 on the winding plate 47 will decrease accordingly, so that the operator can adjust the strength of the support force of the winding plate 47 according to the needs, so that the winding plate 47 can adapt to the tension generated by the alumina continuous fiber during the sintering process in the sintering furnace 1, thereby reducing fiber breakage and ensuring the sintering quality of the alumina continuous fiber.

[0031] The elastic support assembly 5 includes an inner liner 51, a high-temperature resistant spring 52, a limiting cover 53, a support block 58, and a limiting cavity 59. A limiting cover 53 is installed on the upper end face of the support cylinder 46, which limits and blocks the support block 58 to prevent slippage during use. A limiting cavity 59 is formed inside the support cylinder 46, matching both the support block 58 and the inner liner 51. The limiting cavity 59 facilitates the positioning of the support block 58, the inner liner 51, and the high-temperature resistant spring 52 within the support cylinder 46. For internal use, a high-temperature resistant spring 52 is installed inside the limiting cavity 59. The high-temperature resistant spring 52 is made of SPEC high-temperature resistant spring 52. The high-temperature resistant spring 52 made of SPEC high-temperature resistant spring 52 can not only provide elastic support for the support block 58, but also has good high-temperature resistance and can be used in high-temperature environments. An inner liner 51 is installed on the lower side inside the limiting cavity 59. The inner liner 51 is connected to the extension screw 511 by welding. The inner liner 51 can support the bottom of the high-temperature resistant spring 52.

[0032] A support block 58 is provided at the bottom of the support rod 49. The support block 58 can limit and support the support rod 49 to prevent it from shaking or slipping during use. An extension screw 511 is symmetrically arranged on the left and right ends of the inner liner 51. A positioning nut 55 is installed on the annular side of the extension screw 511. The extension screw 511 and the positioning nut 55 can position the inner liner 51. A grip handle 56 is provided on the left end of the extension screw 511. The grip handle 56 is connected to the extension screw 511 by welding, and the grip handle 56 facilitates operation. The operator manually positions the extension screw 511. The support cylinder 46 has symmetrical limit slots 54 on the left and right sides of its annular side. The limit slots 54 match the extension screw 511 and facilitate the vertical movement of the extension screw 511 inside the support cylinder 46. The support cylinder 46 has height scale lines 57 on its annular side and an indicator line (not shown in the figure) on the front side of the annular side of the extension screw 511. The indicator line and height scale lines 57 facilitate the operator's observation of the height of the extension screw 511 so as to make equidistant adjustments to the four sets of inner lining plates 51.

[0033] Working Principle: Before using this device, the operator first loosens the multiple positioning nuts 55 with a wrench. Then, the operator can grasp the handle 56 and move the inner liner 51 via the extension screw 511. During this process, when the inner liner 51 moves outward, it gradually applies pressure to the high-temperature spring 52, increasing the pressure of the high-temperature spring 52 on the support block 58. Simultaneously, the support force of the support rod 49 on the winding plate 47 also increases. Conversely, when the inner liner 51 moves inward, the pressure of the high-temperature spring 52 on the support block 58 gradually decreases, and the support force of the support rod 49 on the winding plate 47 also decreases. This allows the operator to adjust the strength of the support force on the winding plate 47 as needed, enabling it to adapt to the tension generated during the sintering process of the alumina continuous fibers in the sintering furnace 1, thereby reducing fiber breakage and ensuring the sintering quality of the alumina continuous fibers. The indicator lines are also included. The height scale line 57 also makes it convenient for staff to observe the height of the extension screw 511 so as to make equidistant adjustments to the four sets of inner lining sheets 51. After the positions of the four sets of inner lining sheets 51 are adjusted, the alumina continuous fiber to be sintered can be wound onto the outer surface of the winding plate 47. During this process, the staff only needs to rotate the support shaft 41 by using the hand turntable 45 and the insertion rod 44, so that the support shaft 41 can drive the winding plate 47 to rotate together through the follower roller 42, support cylinder 46 and support rod 49, so that the rotating winding plate 47 can wind the alumina continuous fiber to be sintered. The side baffle 48 can also prevent the alumina continuous fiber from slipping outward during the winding process. After the winding is completed, the furnace door of the sintering furnace 1 can be opened, and then the bottom plate 3, support frame 2 and winding assembly 4 can be moved together into the sintering furnace 1 so that the staff can use the sintering furnace 1 to sinter the alumina continuous fiber wound on the outer surface of the winding plate 47.
