Description

Technical Field

[0001] The utility model relates to the technical field of wire wheel fixing, in particular to a multi-specification wire wheel fixing device. Background Technique

[0002] A wire wheel, also known as a textile wheel, is a component that plays an important role in the process of textile processing. It is usually made of metal or plastic and is shaped like a disc. It is widely used in various processes such as fabric weaving, niping, and edging to improve production efficiency and quality. There are many types of wire wheels, which can be selected according to different textile processing requirements and yarn materials.

[0003] Many existing wire wheel fixing devices are designed relatively fixedly and lack flexibility, unable to be adjusted according to wire wheels of different diameters. This results in the need to reconfigure or replace the entire fixing device when replacing wire wheels of different diameters, increasing the operation complexity and cost.

[0004] Therefore, we propose a multi-specification wire wheel fixing device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-specification wire wheel fixing device to solve the problem of single fixing structure proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A multi-specification wire wheel fixing device, including a base and a bracket fixedly connected above the base. One side of the bracket is provided with a bearing, the inner ring of the bearing is fixedly connected with a fixed shaft, a limiting structure is arranged outside the fixed shaft, and an adjusting mechanism is arranged inside the fixed shaft;

[0007] The adjusting mechanism includes a moving unit and a fixing unit;

[0008] The moving unit includes a support seat, a threaded rod, a handle, and an abutting block. The support seat is fixedly connected to one end of the fixed shaft, the threaded rod is threadedly connected inside the support seat, the handle is fixedly connected to the outer end of the threaded rod, and one side of the abutting block is fixedly connected to the other end of the threaded rod;

[0009] The fixing unit includes a through hole, a rectangular groove, a limiting block, a groove, a spring, a movable block, and a fixing ring. The through hole is opened inside the fixed shaft, the rectangular groove penetrates the fixed shaft and extends inward to the through hole, the limiting block is movably connected inside the rectangular groove, the groove is opened on one side of the limiting block, one end of the spring is fixedly connected inside the groove, the other end of the spring is fixedly connected to the movable block, the side of the movable block is fixedly connected to the fixing ring, and the outer side of the fixing ring is fixedly connected to the through hole inside the fixed shaft.

[0010] Preferably, the limiting structure includes a semi-circular groove and a sliding block. The semi-circular groove is formed on the outer side of the fixed shaft and is distributed in a triangular shape. An annular groove is formed on the sliding block. The three sliding blocks are bundled in the annular groove by a strap and slide in the semi-circular groove, which can realize the preliminary positioning and limiting of wire wheels with different diameters, and increase the stability and accuracy of wire wheel installation. The sliding adjustment of the sliding block in the arc-shaped groove enables the device to adapt to wire wheels of various lengths, improving the versatility and flexibility of the device.

[0011] Preferably, there are three rectangular grooves, which intersect with the semi-circular groove and are formed on the outer side of the fixed shaft and are distributed in a triangular shape, providing multi-point support and limitation for the wire wheel, further enhancing the stability and reliability of wire wheel fixation. At the same time, the triangular distribution also improves the structural strength of the device and can withstand greater loads.

[0012] Preferably, one side of the limiting block close to the axis of the fixed shaft is beveled. The bevel design enables the abutting block to conveniently control the limiting block, so as to adapt to wire wheels of different diameters.

[0013] Preferably, there are three groups of fixing units, and the limiting blocks inside them are respectively arranged at the rectangular grooves. The arrangement of multiple groups of fixing units further enhances the stability and reliability of wire wheel fixation, ensuring that it can adapt to wire wheels with different inner diameters.

[0014] Preferably, the threaded rod and the abutting block are arranged inside the through hole, which is convenient for operating the fixing unit.

[0015] Preferably, anti-slip lines are formed on the surface of the limiting block in contact with the wire wheel. The design of the anti-slip lines increases the friction between the abutting block and the wire wheel, preventing the wire wheel from sliding or falling off during the fixing process.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For this multi-specification wire wheel fixing device, by rotating the handle to adjust the position of the abutting block, and then pushing the limiting block to move in the rectangular groove, close fitting of wire wheels with different specifications can be achieved. When the wire wheel needs to be replaced, simply rotate the handle in the opposite direction, and the abutting block will move outward, causing the limiting block to automatically return to the inside of the rectangular groove under the action of the spring, thus quickly releasing the wire wheel.

[0018] 2. For this multi-specification wire wheel fixing device, the sliding block 501 is bundled in the annular groove 502 by a strap and slides in the semi-circular groove 301, effectively restricting the radial movement of the wire wheel on the fixed shaft 3, preventing the wire wheel from shifting or falling off during rotation or operation, and ensuring the stability and safety of the wire wheel.

[0025] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A multi-specification wire wheel fixing device includes a base 1 and a bracket fixedly connected above the base 1. A bearing 2 is provided on one side of the bracket. The inner ring of the bearing 2 is fixedly connected to a fixed shaft 3. By fixedly connecting the fixed shaft 3 to the inner ring, the rotation function of the fixed shaft 3 is realized, while reducing friction and wear, and improving the durability and service life of the device. A limiting structure is provided on the outer side of the fixed shaft 3. As the main support and fixing component of the wire wheel, the fixing and adjustment of wire wheels of different specifications are realized through the limiting structure on the outer side and the internal adjustment mechanism. An adjustment mechanism is provided inside the fixed shaft 3;

[0028] The adjustment mechanism includes a moving unit and a fixing unit;

[0029] The moving unit includes a support base 9, a threaded rod 602, a handle 601 and an abutting block 603. The support base 9 is fixedly connected to one end of the fixed shaft 3. The threaded rod 602 is threadedly connected to the inside of the support base 9. The handle 601 is fixedly connected to the outer end of the threaded rod 602. One side of the abutting block 603 is fixedly connected to the other end of the threaded rod 602. The threaded rod 602 and the abutting block 603 are arranged inside the through hole 302. By rotating the handle 601, the threaded rod 602 is driven to move inside the support base 9, and then the abutting block 603 is pushed to adjust the abutting block 701 to adapt to wire wheels of different specifications, improving the versatility and flexibility of the device.

[0030] The fixing unit includes a through hole 302, a rectangular groove 4, a limiting block 701, a groove 702, a spring 703, a movable block 704 and a fixing ring 8. The through hole 302 is opened inside the fixed shaft 3. The rectangular groove 4 penetrates the fixed shaft 3 and extends inwards to the through hole 302. There are three rectangular grooves 4, which intersect with the semi-circular groove 301 and are arranged on the outer side of the fixed shaft 3 in a triangular distribution. The limiting block 701 is movably connected inside the rectangular groove 4. One side of the limiting block 701 close to the axis of the fixed shaft 3 is beveled. The surface of the limiting block 701 in contact with the wire wheel is provided with anti-slip lines 705. The groove 702 is opened on one side of the limiting block 701. One end of the spring 703 is fixedly connected to the inside of the groove 702. The other end of the spring 703 is fixedly connected to the movable block 704. The side of the movable block 704 is fixedly connected to the fixing ring 8. The outer side of the fixing ring 8 is fixedly connected to the through hole 302 inside the fixed shaft 3. There are three groups of fixing units, and the limiting blocks 701 inside them are respectively arranged at the rectangular grooves 4. These limiting blocks 701 can move inside the rectangular grooves 4, and at the same time, with the elastic force of the spring 703, the inner wall of the wire wheel can be closely attached and adaptively fixed.

[0031] Embodiment 2:

[0032] On the basis of Embodiment 1, the limiting structure includes a semi-circular groove 301 and a sliding block 501. The semi-circular groove 301 is opened on the outer side of the fixed shaft 3 and is arranged in a triangular distribution. An annular groove 502 is opened on the sliding block 501. The three sliding blocks 501 are bundled inside the annular groove 502 and slide in the semi-circular groove 301 to limit the position of the wire wheel on the fixed shaft 2, prevent the wire wheel from shifting or falling off during rotation or operation, and ensure the stability and safety of the wire wheel.

[0033] Working principle: Place the wire reel on the fixed shaft 2 and rotate the handle 601 to drive the threaded rod 602 to move inside the support base 9. Since the threaded rod 602 is fixedly connected to the abutting block 603, the abutting block 603 will move accordingly, and then adjust the limiting block 701. The limiting block 701 moves in the rectangular groove 4 and is simultaneously affected by the elastic force of the spring 703. When the wire reel is placed on the fixed shaft, the limiting block 701 adjusts its position under the movement of the abutting block 603 to achieve tight fitting and adaptive fixation. When the wire reel needs to be replaced, rotate the handle in the opposite direction, and the abutting block 603 moves outward. At this time, the limiting block 701 returns to the inside of the rectangular groove 4 under the action of the spring.

[0034] After the wire reel is fixed, adjust the limiting structure. Its semi-circular groove 301 provides a sliding track for the sliding block 501. The sliding block 501 is bundled inside the annular groove 502 by a strap and can slide in the semi-circular groove 301. This design restricts the position of the wire reel on the fixed shaft 2, preventing it from shifting or falling off during rotation or operation, and ensuring the stability and safety of the wire reel.
