Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a dustproof bearing for an air-jet spinning machine. Background Technology

[0002] An air-jet spinning machine is an advanced piece of equipment that uses airflow technology to stretch and twist fibers into yarn. Compared with traditional ring spinning technology, air-jet spinning (also known as air-jet spinning) has advantages such as high production efficiency, high degree of automation, and good product quality. Since there is a large amount of fiber dust in the working environment of an air-jet spinning machine, the use of bearings with excellent dustproof performance is crucial to ensuring stable operation of the equipment and extending its service life.

[0003] Existing bearings mostly use only a set of sealing gaskets to protect the internal balls. However, this method of protection is not suitable for the small size of dust and fibers in textile environments. Therefore, external dust and other impurities can easily affect the normal use of the bearing. To address this, we propose a dustproof bearing for air-jet spinning machines. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof bearing for an air-jet spinning machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof bearing for an air-jet spinning machine, comprising a fixed cover, a bearing mechanism fixedly installed inside the fixed cover, a support frame fixedly installed outside the fixed cover, two sets of mounting slots on the support frame, a front dustproof mechanism to prevent external dust from entering the bearing mechanism on one side of the bearing mechanism, a fixed mechanism fixedly connected to the side of the fixed cover away from the front dustproof mechanism, and a rear protection mechanism rotatably connected to the fixed mechanism.

[0006] Furthermore, the bearing mechanism includes a fixed outer ring, a movable inner ring, and balls. The fixed outer ring is fixedly installed inside the fixed cover, and balls are arranged between the fixed outer ring and the movable inner ring.

[0007] Furthermore, the front-end dustproof mechanism includes a first dustproof plate and a second dustproof plate. The second dustproof plate is fixedly connected to one side of the fixed outer ring, and the first dustproof plate is fixedly connected to one side of the movable inner ring and outside the second dustproof plate. A gap is left between the first dustproof plate and the second dustproof plate.

[0008] Furthermore, the fixing mechanism includes a fixing plate, a positioning claw, and a limiting slide groove. The fixing cover has multiple sets of locking threaded holes. The fixing plate has a through groove at the position corresponding to the locking threaded holes. A positioning claw is fixedly connected to one edge of the fixing plate. A limiting slide groove is provided on one side of the fixing plate.

[0009] Furthermore, the rear protection mechanism includes a sealing plate, a first sealing ring, a snap-fit ​​frame, and a limiting slider. A snap-fit ​​frame that is sleeved on the outside of the positioning claw is fixedly connected to one edge of the sealing plate. A limiting slider that is inserted into the limiting groove is fixedly connected to one side of the sealing plate. A second sealing ring is fixedly installed on the limiting slider. A first sealing ring is fixedly installed on the sealing plate.

[0010] Furthermore, both the first and second dustproof plates are corrugated.

[0011] Compared with the prior art, the present invention has the following advantages: the fixed cover and support frame provided by the present invention can support the bearing mechanism, the front dustproof mechanism can prevent dust and fibers in the external environment from entering the bearing mechanism, and the rear protection mechanism is installed on the fixed cover through the fixing mechanism. This arrangement can make the rear protection mechanism fit with the external rotating shaft, thereby preventing impurities flying in the external environment from entering the bearing mechanism through the rotating shaft.

[0018] 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.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a dustproof bearing for an air-jet spinning machine, including a fixed cover 1, a bearing mechanism 2 fixedly installed inside the fixed cover 1, a support frame 3 fixedly installed outside the fixed cover 1, two sets of mounting grooves 4 opened on the support frame 3, a front dustproof mechanism 5 is provided on one side of the bearing mechanism 2 to prevent external dust from entering the bearing mechanism 2, a fixed mechanism 6 is fixedly connected to the side of the fixed cover 1 away from the front dustproof mechanism 5, and a rear protection mechanism 7 is rotatably connected to the fixed mechanism 6.

[0020] The fixed cover 1 and support frame 3 can support the bearing mechanism 2, while the front dustproof mechanism 5 can prevent dust and fibers from the external environment from entering the bearing mechanism 2. The rear protection mechanism 7 is installed on the fixed cover 1 through the fixing mechanism 6. This arrangement allows the rear protection mechanism 7 to fit in close contact with the external rotating shaft, thereby preventing impurities flying in the external environment from entering the bearing mechanism 2 through the rotating shaft.

[0021] Please see Figure 1 and Figure 2 The bearing mechanism 2 includes a fixed outer ring 8, a movable inner ring 9, and balls 10. The fixed outer ring 8 is fixedly installed inside the fixed cover 1, and balls 10 are arranged between the fixed outer ring 8 and the movable inner ring 9.

[0022] The fixed outer ring 8 is installed inside the fixed cover 1, while the ball bearing 10 can rotate the movable inner ring 9 and the external shaft.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The front-end dustproof mechanism 5 includes a first dustproof plate 11 and a second dustproof plate 12. The second dustproof plate 12 is fixedly connected to one side of the fixed outer ring 8. The first dustproof plate 11 is fixedly connected to one side of the movable inner ring 9 and outside the second dustproof plate 12. A gap is left between the first dustproof plate 11 and the second dustproof plate 12. Both the first dustproof plate 11 and the second dustproof plate 12 are corrugated.

[0024] The first dustproof plate 11 and the second dustproof plate 12 are respectively attached to the movable inner ring 9 and the fixed outer ring 8, and a gap is left between the first dustproof plate 11 and the second dustproof plate 12 to facilitate the normal rotation of the movable inner ring 9. The first dustproof plate 11 and the second dustproof plate 12 are designed to be corrugated, which can prevent external impurities and fibers from entering between the movable inner ring 9 and the fixed outer ring 8 to a certain extent.

[0025] Please see Figures 1-5 The fixing mechanism 6 includes a fixing plate 14, a positioning claw 16, and a limiting slide groove 17. The fixing cover 1 has multiple sets of locking threaded holes 13. The fixing plate 14 has a through groove 15 at the position corresponding to the locking threaded holes 13. The positioning claw 16 is fixedly connected to one side edge of the fixing plate 14. The limiting slide groove 17 is provided on one side of the fixing plate 14. The rear protection mechanism 7 includes a sealing plate 18, a first sealing ring 19, a snap-fit ​​frame 20, and a limiting slider 21. The snap-fit ​​frame 20, which is sleeved on the outside of the positioning claw 16, is fixedly connected to one side of the sealing plate 18. The limiting slider 21, which is inserted into the limiting slide groove 17, is fixedly connected to one side of the sealing plate 18. A second sealing ring 22 is fixedly installed on the limiting slider 21. The first sealing ring 19 is fixedly installed on the sealing plate 18.

[0026] During the installation of the fixing mechanism 6, the locking threaded hole 13 corresponds to the through groove 15. Then, the locking bolt is threaded through the through groove 15 and connected to the locking threaded hole 13, so that the fixing plate 14 can be fixed to one side of the fixing cover 1. The snap-fit ​​frame 20 is set outside the positioning claw 16, so that the sealing plate 18 can rotate along the positioning claw 16. The limiting slider 21 can extend into the inside of the limiting slide groove 17. The first sealing ring 19 can fit with the external rotating shaft, so that the rotation of the rotating shaft can make the rear protection mechanism 7 rotate along the fixing mechanism 6. The second sealing ring 22 can further prevent external dust and other objects from entering the bearing mechanism 2.

[0027] In use, the fixed cover 1 and support frame 3 support the bearing mechanism 2. The front dustproof mechanism 5 prevents dust and fibers from the external environment from entering the bearing mechanism 2. The rear protection mechanism 7 is installed on the fixed cover 1 via the fixed mechanism 6. This arrangement allows the rear protection mechanism 7 to fit snugly against the external rotating shaft, thus preventing impurities from the external environment from entering the bearing mechanism 2 via the rotating shaft. The fixed outer ring 8 is installed inside the fixed cover 1, and the ball bearings 10 allow the movable inner ring 9 and the external rotating shaft to rotate. The first dustproof plate 11 and the second dustproof plate 12 are respectively attached to the movable inner ring 9 and the fixed outer ring 8, with a gap between them to facilitate the normal rotation of the movable inner ring 9. The 12 is designed in a corrugated shape, which can prevent external impurities and fibers from entering between the movable inner ring 9 and the fixed outer ring 8 to a certain extent. When the fixing mechanism 6 is installed, the locking threaded hole 13 corresponds to the through groove 15. Then, the locking bolt is threaded through the through groove 15 and threaded to the locking threaded hole 13, so that the fixing plate 14 can be attached and fixed to one side of the fixing cover 1. The snap-fit ​​frame 20 is set outside the positioning claw 16, so that the sealing plate 18 can rotate along the positioning claw 16. The limiting slider 21 can extend into the inside of the limiting slide groove 17. The first sealing ring 19 can fit with the external rotating shaft. So that when the rotating shaft rotates, the rear protection mechanism 7 can rotate along the fixing mechanism 6. The second sealing ring 22 can further prevent external dust and other objects from entering the bearing mechanism 2.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
