Description

Technical Field

[0001] This utility model relates to the field of wire winding technology, specifically a winding device for alumina fiber wire. Background Technology

[0002] Alumina fiber is an inorganic high-performance fiber material with alumina (Al2O3) as the main component and a small amount of silica and other components. It is renowned for its excellent high-temperature resistance, superior thermal stability, and low thermal conductivity, while also possessing high hardness, good chemical inertness, and corrosion resistance. The produced alumina fibers need to be wound onto spools.

[0003] In the prior art, the authorized announcement number CN220760605U discloses an alumina guide wire winding device, including a base frame, a first support frame welded to the top of one side of the base frame, a horizontal plate welded to one side of the first support frame, a motor support plate bolted to the horizontal plate, the motor support plate having elongated holes for better fixation to the horizontal plate, a motor bolted to the top of the motor support plate, and a rotating shaft connected to the output shaft of the motor.

[0004] A motor drives a drum to rotate continuously and stably, evenly and orderly winding the wire onto its surface. During winding, as the number of wire layers on the drum surface increases, the drum's outer diameter gradually increases. The motor speed remains constant, and the length of wire wound in each rotation cycle increases with the increasing outer diameter. However, maintaining a constant unwinding speed leads to a mismatch between the wire demand at the winding end and the supply speed at the unwinding end. This speed difference creates excessive tension on the wire. When the tension exceeds the wire's tensile strength, a wire breakage accident occurs, affecting production efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to provide a winding device for alumina fiber yarn to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for alumina fiber thread, comprising a base, detection gratings fixedly installed on both sides of the base, a vertical plate fixedly installed on one side of the base, a positioning mechanism installed on the vertical plate, a drum connected to the positioning mechanism, the positioning mechanism including a bearing seat fixedly installed on the vertical plate, a drive shaft rotatably installed on the bearing seat, a limit plate fixedly installed on the drive shaft, a sliding sleeve slidably installed on the drive shaft, a linkage rod rotatably installed on the sliding sleeve, a positioning plate rotatably installed at the end of the linkage rod, a threaded rod slidably installed inside the drive shaft, a connecting block fixedly installed on the threaded rod, and the end of the connecting block fixedly installed on the sliding sleeve, and a drive mechanism fixedly installed on one side of the vertical plate.

[0007] Preferably, the drive shaft has a movable groove, the connecting block is movably mounted on the drive shaft through the movable groove, a nut is rotatably mounted on one end of the drive shaft and the nut is threaded onto a threaded rod, and a guide wheel is rotatably mounted on one end of the limiting plate and the guide wheel is slidably mounted on the limiting plate.

[0008] Preferably, a bearing is installed inside the bearing housing, and the drive shaft is rotatably mounted on the bearing housing via the bearing.

[0009] Preferably, the bearing housing is connected to bolts, the bearing housing is fixedly installed on the upright plate by bolts, and the positioning plate is connected to the sliding sleeve by a linkage rod.

[0010] Preferably, the drive mechanism includes a protective cover fixedly installed on the outside of the upright plate and a large gear fixedly installed on the drive shaft. An electric cylinder and a servo motor are fixedly installed on the protective cover. A limit sleeve is fixedly installed at the output end of the electric cylinder. The limit sleeve has a slot. A small gear is fixedly installed at the output end of the servo motor.

[0011] Preferably, the limiting sleeve is movably installed inside the protective cover via an electric cylinder, and the limiting sleeve is aligned with the nut front and back.

[0012] Preferably, the protective cover has a through hole, through which the output end of the servo motor extends into the protective cover.

[0013] Preferably, the large gear is rotatably mounted inside the protective cover via a drive shaft, and the small gear meshes with the large gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this application, when the drive shaft rotates, an electric cylinder can be used to drive the limiting sleeve forward, causing the nut to engage with the front end of the limiting sleeve, thereby restricting the rotation of the nut. In this case, the threaded rod will rotate inside the nut, thus achieving a telescopic action. When the threaded rod performs the telescopic action, it will drive the sliding sleeve to telescopically move synchronously, causing the positioning plate on the linkage rod to unfold or retract, thereby fixing drums of different specifications onto the drive shaft and facilitating the winding operation.

[0016] 2. In this application, after the servo motor is started, it drives the pinion to rotate. The rotation of the pinion drives the large gear to rotate, which in turn drives the drive shaft to rotate. The rotation of the drive shaft causes the drum fixed on it to rotate, thereby realizing the operation of winding the fiber thread onto the drum. During the winding process, the detection grating can detect the thickness of the thread on the drum. At the same time, the servo motor can adjust the speed of the drum to reduce the possibility of thread breakage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a winding device for alumina fiber thread, including a base 1, detection gratings 2 fixedly installed on both sides of the base 1, a vertical plate 4 fixedly installed on one side of the base 1, a positioning mechanism 5 installed on the vertical plate 4, a roll 3 connected to the positioning mechanism 5, and a driving mechanism 6 fixedly installed on one side of the vertical plate 4.

[0025] Specifically, the detection grating 2 on the base 1 can detect the thickness of the wire on the spool 3. Through the cooperation of the positioning mechanism 5 and the drive mechanism 6, the fiber wire can be wound up, and the risk of wire breakage can be reduced during the winding process.

[0026] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 5 includes a bearing seat 501 fixedly mounted on the upright plate 4, a drive shaft 503 rotatably mounted on the bearing seat 501, a limit plate 511 fixedly mounted on the drive shaft 503, a sliding sleeve 510 slidably mounted on the drive shaft 503, a linkage rod 508 rotatably mounted on the sliding sleeve 510, a positioning plate 504 rotatably mounted at the end of the linkage rod 508, a threaded rod 507 slidably mounted inside the drive shaft 503, a connecting block 506 fixedly mounted on the threaded rod 507, and the end of the connecting block 506 fixedly mounted on the sliding sleeve 510, a movable groove 505 is provided on the drive shaft 503, the connecting block 506 is movably mounted on the drive shaft 503 through the movable groove 505, a nut 509 rotatably mounted on one end of the drive shaft 503, and the nut 509 is threaded onto the threaded rod 507, and a guide wheel 502 rotatably mounted on one end of the limit plate 511, and the guide wheel 502 is slidably mounted on the limit plate 511.

[0027] Specifically, when the drive shaft 503 rotates, the electric cylinder 603 pushes the limiting sleeve 602 forward, causing the nut 509 to engage with the front end of the limiting sleeve 602, thus restricting the rotation of the nut 509. At this time, the threaded rod 507 rotates inside the nut 509, thereby achieving a telescopic action. When the threaded rod 507 telescopically moves, it drives the sliding sleeve 510 to telescopically extend and retract synchronously, causing the positioning plate 504 on the linkage rod 508 to unfold or retract. In this way, different sized drums 3 can be fixed on the drive shaft 503, facilitating winding operations.

[0028] Example 3: Figure 2 , Figure 3 and Figure 5 As shown, the drive mechanism 6 includes a protective cover 601 fixedly installed on the outside of the upright plate 4 and a large gear 607 fixedly installed on the drive shaft 503. An electric cylinder 603 and a servo motor 605 are fixedly installed on the protective cover 601. A limiting sleeve 602 is fixedly installed at the output end of the electric cylinder 603. The limiting sleeve 602 has a slot 604. A small gear 606 is fixedly installed at the output end of the servo motor 605. The limiting sleeve 602 is movably installed inside the protective cover 601 through the electric cylinder 603, and the limiting sleeve 602 is aligned with the nut 509.

[0029] Specifically, after the servo motor 605 is started, it drives the pinion 606 to rotate. The rotation of the pinion 606 drives the large gear 607 to rotate. The rotation of the large gear 607 drives the drive shaft 503 to rotate. The rotation of the drive shaft 503 drives the drum 3 fixed on it to rotate, thereby winding the fiber thread onto the drum 3.

[0030] During the winding process, the detection grating 2 can detect the thickness of the wire on the drum 3. At the same time, the servo motor 605 can adjust the rotation speed of the drum 3 to reduce the risk of wire breakage.

[0031] Working principle: After the servo motor 605 is started, it will drive the pinion 606 to rotate. After the pinion 606 rotates, it will drive the large gear 607 to rotate. After the large gear 607 rotates, it will drive the drive shaft 503 to rotate. When the drive shaft 503 rotates, it can drive the limit sleeve 602 to move forward through the electric cylinder 603, so that the nut 509 is stuck at the front end of the limit sleeve 602, restricting the rotation of the nut 509. At this time, the threaded rod 507 will rotate with the nut 509, so that the threaded rod 507 performs a telescopic action. When the threaded rod 507 performs a telescopic action, it drives the sliding sleeve 510 to perform a telescopic action, so that the positioning plate 504 on the linkage rod 508 unfolds or retracts, so as to fix the drums 3 of different sizes on the drive shaft 503 for easy winding operation. After the drive shaft 503 rotates, it will drive the drum 3 fixed on it to rotate, thereby winding the fiber thread onto the drum 3. During the winding process, the detection grating 2 can detect the thickness of the thread on the drum 3 so that the servo motor 605 can adjust the speed of the drum 3 to reduce the risk of thread breakage.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
