[0002] Wooden beads are widely used in the production of handicrafts, furniture and decorations. Surface polishing is a key process to ensure aesthetics and functionality. In the traditional wooden bead polishing process, manual or semi-automatic fixing mechanisms are usually used to hold the wooden beads.

[0003] Existing wooden bead fixing structures lack an effective rotation drive mechanism, requiring operators to frequently adjust the bead position manually to ensure even sanding. This not only increases the workload of workers but also easily leads to uneven sanding due to human factors, thus affecting the production quality of the wooden beads. Therefore, we provide a fixing mechanism for wooden bead sanding. Utility Model Content

[0018] 6. Load-bearing round support. Detailed Implementation

[0019] 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.

[0020] Example 1 Existing wooden bead fixing mechanisms rely on manual adjustment of the bead's position during sanding, which can easily reduce sanding efficiency and the quality of bead production. This embodiment provides a wooden bead fixing mechanism that can automatically rotate the fixed wooden beads, thereby quickly adjusting the sanding position of the beads. It can also fix wooden beads of different sizes, improving both sanding efficiency and the quality of bead production. Please refer to... Figure 1 - Figure 6 This fixing mechanism for sanding wooden beads includes a placement platform 2 and a fixing frame 3 installed on the top and rear sides of the fixed base 1. A load-bearing round support 6 for placing wooden beads is detachably and rotatably mounted on the top of the placement platform 2. This detachable design allows for easy replacement of the load-bearing round support 6 according to the size of the wooden beads, improving the convenience of sanding. Furthermore, the internal arc structure of the load-bearing round support 6 matches the curved surface of the wooden beads, better conforming to the bottom of the beads and providing stable support. This prevents the wooden beads from shaking due to uneven force during sanding, further ensuring the stability and safety of the wooden beads during sanding and contributing to improved sanding quality. The fixing frame 3 is equipped with a fixed rotation mechanism 4 that drives the wooden beads to rotate. The fixed rotation mechanism 4 automatically drives the wooden beads to rotate, eliminating the need for manual adjustment and improving sanding efficiency.

[0021] The existing wooden bead fixing structure lacks an effective rotation drive, requiring frequent manual adjustments to the bead position for even sanding. This increases the operator's workload and is prone to uneven sanding due to human error, affecting the quality of wooden bead production. To address these issues, a fixed rotation mechanism 4 includes two symmetrically arranged fixing frames 41. Small vacuum cleaners are installed inside the front side of the two fixing frames 41 near the placement platform 2. These vacuum cleaners promptly collect the powder generated during wooden bead sanding and discharge it through a connection to a pipe on the outside of the fixing frames 41, preventing powder from spreading into the air, improving the sanding environment, and reducing the health impact on operators. The connection points between the small vacuum cleaners and the pipes are located on the outside of the fixing frames 41, facilitating the discharge of sanding powder collected by the vacuum cleaners through the pipes. This simplifies pipe installation and maintenance, making the vacuuming process smoother and effectively improving the efficiency of sanding powder collection and processing, further improving the sanding environment. A drive motor 42 is installed at the front end of the two fixing frames 41. The output shaft of the drive motor 42 is equipped with components distributed on the fixing frames 41. 1. An internal connecting rod 43 is provided. Multiple sets of worm gear sleeves 44 are installed on the outer wall of the connecting rod 43. Each set of fixed frames 41 is rotatably connected to a number of rollers 45 equal to the number of worm gear sleeves 44. The outer wall of the rollers 45 is provided with several protrusions to increase the friction between the rollers 45 and the wooden beads. When the rollers 45 drive the wooden beads to rotate, it can ensure that the wooden beads rotate stably and avoid slippage, which will affect the sanding effect. The protrusions are made of rubber, which can enhance the fit and grip between the rollers 45 and the wooden beads by utilizing the elasticity and friction of the rubber, ensuring that the wooden beads are not easy to slip when they are driven to rotate, and ensuring the stability of rotation. At the same time, because the rubber is relatively soft, it can reduce the squeezing and scratching of the surface of the wooden beads by the rollers 45, and avoid damaging the wooden beads. A worm wheel 46 that meshes with the worm gear sleeve 44 is installed at the top of each set of rollers 45.

[0022] The mounting frame 3 is equipped with a drive mechanism 5 that moves the two sets of fixed rotation mechanisms 4 closer together or further apart. The drive mechanism 5 can fix wooden beads of different sizes, improving the adaptability of the device.

[0023] After the wooden bead is placed on the load-bearing round support 6 and clamped by the two side rollers 45, the drive motor 42 starts, and its output shaft drives the connecting rod 43 and the worm sleeve 44 to rotate. The worm sleeve 44 meshes with the worm wheel 46 at the top of the roller 45, so that multiple rollers 45 rotate synchronously. The friction between the rubber protrusions on the outer wall of the roller 45 and the wooden bead drives the wooden bead to rotate automatically. In conjunction with the polishing device installed on the front of the fixed frame 3, different surfaces of the wooden bead can be polished quickly, improving the polishing effect. At the same time, the small vacuum cleaner in the fixed frame 41 can absorb the powder generated by polishing, avoiding the powder from affecting the polishing effect of the wooden bead. Thus, the wooden bead can be automatically rotated and polished in a fixed state, improving the production quality of the wooden bead.

[0024] Example 2 Based on Example 1, such as Figure 1 - Figure 5 As shown, the existing wooden bead fixing mechanism relies on manual adjustment of the wooden bead grinding position, which easily reduces grinding efficiency and wooden bead production quality. However, traditional clamps are usually designed with a fixed spacing and cannot be flexibly adjusted to adapt to wooden beads of different diameters, resulting in small wooden beads not being firmly clamped or large wooden beads not being fixed. Therefore, this device is also equipped with a structure for fixing wooden beads of different sizes.

[0025] Traditional clamps often have fixed spacing, making it difficult to adjust and adapt to wooden beads of different diameters. This results in insecure clamping of small beads or failure to secure large beads. To address these issues, the drive mechanism 5 includes an inner groove 51 within the fixed frame 3. A bidirectional lead screw 52 is rotatably connected inside the inner groove 51. When the bidirectional lead screw 52 rotates, the movable mounting seats 54, threaded at both ends, can move synchronously towards or away from each other under the constraint of limit rods 53. This causes the two sets of fixed frames 41 to move closer or further apart to accommodate the fixing needs of wooden beads of different sizes. Furthermore, limit rods 53 are installed at the four corners inside the inner groove 51, symmetrically distributed in pairs around the movable mounting seats 54, precisely limiting the movement direction of the movable mounting seats 54. To prevent it from shifting or rotating during movement, and to ensure that the two sets of fixed frames 41 always maintain a stable and symmetrical movement, thus ensuring the stability and reliability of fixing the wooden beads, the two ends of the outer wall of the bidirectional screw 52 are threaded with movable mounting seats 54 that are slidably connected to multiple sets of limit rods 53, and the outer side of the movable mounting seats 54 is connected to the connecting end of the fixed frame 41. A bevel gear 55 is installed in the middle part of the bidirectional screw 52, ​​and an asynchronous motor 56 is installed on the upper back of the fixed frame 3. A bevel gear 57 that meshes with bevel gear 55 is installed on the output shaft of the asynchronous motor 56.

[0026] The asynchronous motor 56 drives the second bevel gear 57 to rotate. Since the second bevel gear 57 meshes with the first bevel gear 55, it drives the bidirectional lead screw 52 to rotate. The reverse threads at both ends of the bidirectional lead screw 52 drive the movable mounting base 54 to slide along the limiting rod 53, so that the two sets of fixing frames 41 move towards or away from each other to accommodate wooden beads of different sizes. This allows for the fixing of wooden beads of different sizes, improving the adaptability of the device.
