[0024] The embodiments of the present application will be described in detail below with reference to the drawings.
[0025] Embodiment: as Figures 1 to 6As shown, an auxiliary fiber unwinding device is provided, the main purpose of which is to assist the fiber unwinding and ensure the stability of the fiber during the unwinding process, thereby ensuring the quality of the fiber. The above-mentioned auxiliary fiber unwinding device is installed on the bobbin 3 for winding the fiber, on the one hand, to ensure the stability of the unwinding device during installation and use, and on the other hand, to facilitate the installation of the unwinding device and reduce its space occupation. In order to facilitate winding, the above-mentioned bobbin 3 is usually provided in a columnar structure. In order to facilitate the installation of the above-mentioned auxiliary fiber unwinding device on the above-mentioned bobbin 3, the top of the above-mentioned bobbin 3 in this embodiment is provided with an opening. Specifically, the unwinding device mainly consists of a fixing member 1, a main shaft 2, a support rod 5 provided with a guide hook 9 and arranged horizontally, and a rotating assembly capable of driving the above-mentioned support rod 5 to rotate around the above-mentioned main shaft 2. The above-mentioned fixing member 1 is installed at the opening of the above-mentioned bobbin 3, and the purpose of the above-mentioned fixing member 1 is mainly to fix the device as a whole on the bobbin 1, and in this process, the above-mentioned fixing member 1 also plays a connecting role. The above-mentioned main shaft 2 is a central shaft, which successively passes through the above-mentioned rotating assembly and the above-mentioned fixing member 1 from above the rotating assembly and is partially located in the above-mentioned bobbin 3. By changing the position of the main shaft 2, the height between the above-mentioned support rod 5 and the above-mentioned bobbin 3 can be changed, and thus the height of the air ring can be changed. The air ring is formed due to the rotational movement of the fiber around the main shaft 2, and when the unwinding speed exceeds a certain value, the air ring is formed. The air ring forms tension on the fiber, and the tension changes with the change of the height and diameter of the air ring, thereby affecting the quality of the fiber. The above-mentioned support rod 5 is two, and the two support rods 5 are symmetrically arranged along the central axis of the main shaft 2. Correspondingly, the number of the above-mentioned guide hooks 9 is two. The above-mentioned guide hooks 9 are arranged at the ends of the above-mentioned support rods 5, and the fiber is wound upward through the guide hooks 9. The fiber passes through the above-mentioned guide hooks 9 when unwinding, which can make the formed air ring more stable.
[0026] The distance between the two above-mentioned guide hooks 9 is greater than the outer diameter of the above-mentioned bobbin 3, which can provide a horizontal force during unwinding to prevent violent unwinding from tearing the cake. The above-mentioned support rod 5 is arranged horizontally to provide a certain horizontal force during the winding process of the fiber, which can partially offset the force in the longitudinal direction that the fiber suffers in the winding process in the prior art, thereby reducing the probability of violent tearing and other phenomena caused by excessive force in the longitudinal direction, ensuring the quality of the fiber during the production and winding process, and at the same time, since the length of the support rod 5 with the guide hook 9 is fixed, the air ring formed by the fiber during unwinding is stable, thereby ensuring the stability of the fiber, reducing the rate of defective products, reducing the production cost while reducing the user's use cost, thereby enhancing the user's use experience, which is conducive to the promotion and application of the above-mentioned auxiliary fiber unwinding device in the market.
[0027] The rotating assembly in the embodiment mainly consists of a protective sleeve 4 and a rotating bearing 10 arranged in the protective sleeve 4. The rotating bearing 10 is sleeved on the main shaft 2, and the protective sleeve 4 is used to protect the main shaft 2 from abrasion, prolong the service life of the main shaft 2, and reduce the use cost. In addition, the protective sleeve 4 can prevent dust, moisture and other impurities from entering the rotating bearing 10, thereby ensuring the use performance of the rotating bearing 10. The protective sleeve 4 has a mounting groove for mounting the rotating bearing 10, thereby reducing the mounting difficulty. The rotating bearing 10 plays a key role in matching the fiber unwinding speed during the unwinding process, thereby ensuring the stability of the unwinding.
[0028] The two support rods 5 are connected by a ring-shaped sleeve 8, which forms a whole structure. On the one hand, the ring-shaped sleeve 8 can improve the stability of the whole device during operation, and on the other hand, the ring-shaped sleeve 8 can make the two support rods 5 rotate synchronously, thereby ensuring the stability of the whole unwinding device and reducing the vibration or swing caused by unstable connection between the support rods 5. The outer wall of the protective sleeve 4 forms a ring-shaped groove 4-1, and the ring-shaped sleeve 8 is sleeved in the ring-shaped groove 4-1. Specifically, the ring-shaped sleeve 8 is embedded in the ring-shaped groove 4-1, which can ensure the correct position of the support rod 5 on the protective sleeve 4 and prevent the support rod 5 from shifting or vibrating during operation, thereby ensuring the stability and reliability of the whole device. In the embodiment, the sleeving of the ring-shaped sleeve 8 can reduce the direct contact and friction between the support rod 5 and the protective sleeve 4, thereby reducing the abrasion and prolonging the service life of the support rod 5. The ring-shaped sleeve 8 connects the two support rods 5, thereby enhancing the integrity and rigidity of the whole structure and making the structure more solid.
[0029] In order to prevent the fixed part 1 from moving upward and affecting the stability of the whole device during use, a limiting part one 6 is arranged on the outer surface of the main shaft 2 above the fixed part 1. The main shaft 2 at this position has external threads, and the limiting part one 6 can be a limiting nut with simple structure, high economic practicality, and limiting and stabilizing functions, which can reduce the use cost. Similarly, in order to prevent the protective sleeve 4 from shifting or sliding out of the main shaft 2, a limiting part two 7 is arranged on the outer surface of the main shaft 2 above the protective sleeve 4. The limiting part two 7 can also be a limiting nut with simple structure, high economic practicality, and limiting and stabilizing functions, and the main shaft 2 at this position also has external threads, which facilitates connection and reduces assembly difficulty.
[0030] In order to reduce the installation difficulty and improve the installation rate, the fixed part 1 can be clamped at the opening of the bobbin 3. The outer diameter of the fixed part 1 is greater than the outer diameter of the bobbin 3, and the inner diameter of the fixed part 1 is slightly larger than the inner diameter of the bobbin 3.
[0031] To facilitate the adjustment of the height between the support rod 5 and the cylinder 3, i.e. the height of the gas ring, the main shaft 2 can be a fully threaded shaft. Since threads can provide precise linear movement, a fully threaded shaft can be easily adjusted in height and precisely positioned to meet the user's needs.
[0032] The aforementioned guide hook 9 is coiled in a pig's tail shape. This pig-tail-shaped coil helps to effectively bind the fiber as it passes through the guide hook 9 for unwinding, preventing the fiber from detaching from the guide hook 9 and thus ensuring the stability of the fiber during the unwinding process. The aforementioned guide hook 9 is made of ceramic material, which helps to reduce the wear and tear on the fiber during the unwinding process, thereby ensuring the quality of the fiber.
[0033] After the fiber undergoes heat treatment, it is unwound. In order to reduce friction, reduce fuzz, and eliminate static electricity, the fiber often needs to be oiled. The unwinding device in this embodiment ensures stable unwinding of the fiber while also making the oiling more uniform.
[0034] The auxiliary fiber unwinding device in this embodiment operates primarily based on the fiber unwinding speed to ensure fiber stability during the unwinding process and reduce fiber strength loss. During use, the length between the two guide hooks 9 can be approximately 5 cm longer than the outer diameter of the entire fiber roll (i.e., the fiber wound around the bobbin 3) to ensure the fiber is subjected to longitudinal force, reducing fiber adhesion during unwinding. A fiber unwinding speed of approximately 300 m / min is recommended; excessively fast unwinding speeds can worsen adhesion and damage the unwinding device.
[0035] This embodiment presents an auxiliary fiber unwinding device with an ingenious structure. It comprises a fixing component 1, a main shaft 2, a support rod 5 with a guide hook 9, and a rotating assembly that drives the support rod 5 to rotate around the main shaft 2. The support rod 5 is arranged laterally, providing a certain lateral force during fiber winding. This lateral force can partially offset the longitudinal force experienced by the fiber during winding in existing technologies, thereby reducing the probability of violent tearing caused by excessive longitudinal force. This ensures the quality and stability of the fiber during manufacturing and winding, reduces the defect rate, lowers manufacturing costs, and reduces user operating costs, thus enhancing the user experience and facilitating the market promotion and application of the aforementioned auxiliary fiber unwinding device.
