Description

Technical Field

[0001] This application relates to the field of yarn processing equipment, and in particular to an active unwinding device for yarn. Background Technology

[0002] In the textile industry, yarn spools are frequently used. During the textile process, the yarn on the yarn spool needs to be unwound for textile production. However, because the yarn on the yarn spool is irregularly wound, the tightness of the yarn varies during unwinding due to the different positions of the yarn winding, which affects the textile effect.

[0003] Traditional yarn unwinding equipment relies heavily on manual operation, which is inefficient and prone to errors. With the development of technology and the continuous improvement of mechanization and automation, yarn unwinding equipment is gradually developing towards intelligence and high efficiency, which significantly improves production efficiency and product quality, reduces labor intensity, and reduces the impact of human factors, thereby promoting the overall progress of the textile industry.

[0004] Existing yarn unwinding equipment typically employs a passive unwinding method, adjusting yarn tension through a tension control device. Common methods include using spring tensioners, friction discs, and pneumatic tensioners. While these methods can ensure yarn stability to some extent, they still have some shortcomings in practical applications. For example, spring tensioners are susceptible to changes in ambient temperature and humidity, leading to unstable tension; friction discs wear out significantly after prolonged use, requiring frequent replacement; and pneumatic tensioners have complex structures, high maintenance costs, and slow response times. Therefore, designing a yarn unwinding device that effectively reduces yarn knotting and tangling while ensuring a smooth and reliable unwinding process has become an urgent technical problem to be solved. Utility Model Content

[0005] To address the problem of yarn unwinding in the prior art, this application provides an active yarn unwinding device.

[0006] This application provides a yarn active unwinding device, which adopts the following technical solution:

[0007] An active unwinding device for yarn includes a rotating device for rotating a yarn roll and a control device for controlling the yarn tension. The control device includes a control board with a control space. A yarn take-up device for controlling the yarn is slidably disposed in the control space. The control board is also provided with a sensing device for sensing the position of the yarn take-up device.

[0008] By adopting the above technical solution, this active yarn unwinding device can achieve automatic and stable yarn unwinding. The cyclops in the control device can slide within the control space, adjusting its position according to the actual needs of the yarn to ensure uniform yarn tension during the unwinding process. Simultaneously, the sensing device can monitor the position changes of the cyclops in real time and provide timely feedback to external equipment, further improving the accuracy and reliability of yarn unwinding. This design not only improves production efficiency but also significantly enhances the quality of textiles, reducing the scrap rate caused by yarn knots or tangles.

[0009] Preferably, the control panel is provided with sliding grooves on both sides of the control space for sliding of the convergent device, and the two sides of the convergent device are respectively slidably engaged with the two sliding grooves.

[0010] By adopting the above technical solution, a sliding groove is set on the control panel, and the two sides of the yarn gatherer slide in the sliding groove to ensure the stable movement of the yarn gatherer in the control space. This effectively prevents the yarn from knotting or tangling due to the positional deviation of the yarn gatherer during unwinding, and further improves the stability and efficiency of yarn unwinding.

[0011] Preferably, the gatherer includes a sliding plate, the two sides of which are slidably connected to two sliding grooves, and the sliding plate is also provided with ceramic eyelets for yarn to pass through.

[0012] By adopting the above technical solution, the two sides of the sliding plate are slidably connected to the two sliding grooves, which ensures the stable movement of the take-up device in the control space and avoids deviation caused by mechanical vibration or external interference. The ceramic eye set on the sliding plate not only has good wear resistance and corrosion resistance, but also effectively reduces the frictional resistance when the yarn passes through, preventing the yarn from breaking or being damaged, thereby ensuring the smooth and reliable unwinding process of the yarn.

[0013] Preferably, the rotating device includes a base, on which a rotating rod for placing a yarn roll is rotatably mounted, and the axis of rotation of the rotating rod is the axis of rotation of the rotating rod.

[0014] By adopting the above technical solution, the rotating rod on the base can not only support the yarn roll, but also rotate freely on its axis, so that the yarn roll can be unwound as soon as possible, further improving textile quality and production efficiency.

[0015] Preferably, a rotating block is rotatably mounted on the base, a rotating rod is vertically rotatably mounted on the rotating block, the rotation axis of the rotating block is horizontally positioned, and the rotation axis of the rotating rod is perpendicular to the rotation axis of the rotating block.

[0016] By adopting the above technical solution, the design of the rotating block allows the yarn roll to be flexibly adjusted in multiple directions, choosing whether the yarn roll is placed horizontally or vertically, ensuring that the yarn is unwound evenly and stably, thereby improving textile quality and production efficiency.

[0017] Preferably, the end of the rotating rod near the base is also threadedly connected to a support tray, and the end of the rotating rod away from the support tray is provided with a threaded hole. A limit frame is threadedly connected to the threaded hole, and the limit frame and the support tray form a limiting space for limiting the yarn roll.

[0018] By adopting the above technical solution, the bearing tray threaded to one end of the rotating rod and the limiting frame threaded to the threaded hole on the other end together form a limiting space for limiting the yarn roll. This design can not only ensure that the yarn roll is stably fixed during unwinding and prevent the yarn from knotting or tangling due to shaking or displacement, but also facilitate the quick and easy replacement of different yarn rolls, improving the ease of operation and work efficiency of the equipment.

[0019] Preferably, the sliding plate has weight-reducing holes.

[0020] By adopting the above technical solution, weight reduction holes are provided on the sliding plate, which can reduce the overall weight of the sliding plate, reduce the motion inertia of the control device, improve the response speed and accuracy during the yarn unwinding process, and ensure that the yarn is more stable and reliable during the unwinding process.

[0021] Preferably, the sensing device includes laser sensors disposed on the upper and lower sides of the control space.

[0022] By adopting the above technical solution, the laser sensor can monitor the position change of the head receiver in the control space in real time, and send signals to external devices in a timely manner to adjust the unwinding speed, so as to ensure smooth unwinding.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a control board and a yarn gatherer, and using a sensing device to monitor the position of the yarn gatherer in real time, the tension of the yarn can be dynamically adjusted, effectively reducing yarn knotting and tangling, and improving the smoothness and reliability of the unwinding process.

[0025] 2. The sliding fit between the groove on the control panel and the gatherer ensures the stability and accuracy of the gatherer during movement, further improving the control accuracy of yarn tension;

[0026] 3. The design of the rotating device allows the yarn roll to rotate freely in multiple directions, avoiding the risk of yarn twisting and breakage caused by rotation in one direction, thus improving the overall performance and service life of the equipment. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0031] This application discloses an active unwinding device for yarn.

[0032] Reference Figure 1 and Figure 2 An active unwinding device for yarn includes a rotating device 1 for rotating a yarn roll and a control device 2 for controlling the yarn tension. The control device 2 includes a control plate 21 with a control space 22. A yarn gatherer 3 for controlling the yarn is slidably disposed within the control space 22. The control plate 21 also has a sensing device 4 for sensing the position of the yarn gatherer 3. In use, the yarn roll is mounted on the rotating device 1, and then the yarn on the yarn roll is passed through the yarn gatherer 3 and connected to an external device. When the external device is running, the yarn on the yarn roll begins to unwind, and then the yarn gatherer 3 slides up and down to maintain stable unwinding. When the yarn gatherer 3 slides to the upper or lower edge of the control space 22, the sensing device 4 sends a signal to the external device to adjust the unwinding speed to ensure smooth yarn unwinding. This design can effectively reduce yarn knotting and entanglement, while ensuring a smooth and reliable unwinding process.

[0033] Reference Figure 1 and Figure 2The rotating device 1 includes a base 11, on which a rotating block 12 is rotatably mounted. The rotating shaft of the rotating block 12 is horizontally mounted, and a rotating rod 13 is vertically mounted on the rotating block 12. The rotation axis of the rotating rod 13 is the axis of the rotating rod 13 and is perpendicular to the axis of the rotating block 12. A support tray 5 is threadedly connected to one end of the rotating rod 13 near the base 11, and a threaded hole 6 is provided at the other end of the rotating rod 13 away from the support tray 5. A limit frame 7 is threadedly connected to the threaded hole 6, and a limiting space 8 is formed between the limit frame 7 and the support tray 5 for limiting the yarn roll. The setting of the limiting space 8 allows the yarn roll to be stably mounted on the rotating rod 13, and the yarn roll can be adjusted to be placed vertically or horizontally according to the actual situation, thereby enhancing the applicability of the equipment and ensuring the stability of unwinding.

[0034] Reference Figure 1 and Figure 2 The control panel 21 has sliding grooves 23 on both the left and right sides within the control space 22. The yarn gatherer 3 includes a sliding plate 31, with each side of the sliding plate 31 slidingly engaging with the two sliding grooves 23. The yarn gatherer 3 also includes a ceramic eye 32 fixedly disposed in the center of the sliding plate 31 for yarn to pass through. The ceramic eye 32 has good wear resistance and a low coefficient of friction, which can effectively reduce the wear of the yarn when passing through and improve the quality of the yarn. In addition, other materials such as polyurethane or nylon can be selected for the eye to adapt to different usage environments. The sliding plate 31 is also provided with weight reduction holes 9 to reduce the resistance of the sliding plate 31 when sliding up and down, making it easier for the yarn gatherer 3 to automatically adjust its position and maintain stable yarn unwinding.

[0035] Reference Figure 1 and Figure 2 The sensing device 4 includes laser sensors installed on the upper and lower sides of the control space 22. The laser sensors can monitor the position of the retractor 3 in real time and adjust the working state of the control device 2 in a timely manner through feedback signals, thereby achieving precise tension control.

[0036] The implementation principle of this application embodiment is as follows: The rotating device 1, through the combined design of the base 11, rotating rod 13, and rotating block 12, enables the yarn roll to maintain a stable rotational state at different angles. The base 11 provides a solid foundation, and the dual rotational design of the rotating rod 13 and rotating block 12 allows it to flexibly adapt to various working conditions. The control device 2, through the combined design of the control column, control space 22, and take-up device 3, achieves precise control of yarn tension. The sensing device 4 on the control column monitors the position of the take-up device 3 in real time, and the height of the take-up device 3 is adjusted by external equipment to maintain constant yarn tension. The take-up device 3 adopts the design of sliding plate 31 and ceramic eye 32 to ensure smooth and wear-resistant yarn passage, while the design of weight-reducing hole 9 reduces weight and improves response speed. The entire system, through the reasonable combination of mechanical structure and material selection, achieves an efficient and reliable yarn unwinding process, effectively avoiding problems such as yarn knotting and entanglement in traditional equipment, and significantly improving production efficiency and product quality.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
