Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yarn processing, in particular to a yarn feeding device of a two-for-one twisting machine. Background Art
[0002] The two-for-one twister is a twisting device, which is essentially a doubling device (multiple strands are combined into one strand). It can achieve two twists in one turn, and the twisting efficiency is several times higher than that of traditional twisting equipment.
[0003] In the existing technical context, the yarn is not actively pulled through the machine, but is passively wound and twisted as the twisting unit rotates. This passive yarn drawing mode can lead to unstable yarn tension, especially when the bobbin diameter changes. As the yarn is gradually unwound from the surface of the bobbin to the center, the unwinding diameter decreases. Without an appropriate tension control system, the yarn tension will gradually increase, affecting the twist quality and uniformity in the subsequent weaving process. Unstable tension not only affects the structural uniformity of the yarn but may also cause physical damage to the yarn. Therefore, we provide a yarn feeding device for a two-for-one twister. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a yarn feeding device for a two-for-one twister.

[0022] Example 1
[0023] like Figure 1-2 As shown, the utility model provides a technical solution: a yarn feeding device for a two-for-one twisting machine, comprising: a processing yarn 1, a yarn bobbin 4 is provided at one end of the processing yarn 1, a backing ring 5 is provided at one end of the yarn bobbin 4, a protective tube 6 is provided on the outer surface of the yarn bobbin 4, a bearing group 7 is provided at the bottom of the backing ring 5, a damper 8 is provided at the bottom of the bearing group 7, a yarn can 3 is provided on the outer surface of the damper 8, and a support frame 13 is provided at the bottom of the yarn can 3;
[0024] One end of the processed yarn 1 is wound in the yarn bobbin 4, one end of the yarn bobbin 4 is placed on the pad ring 5, the inner surface of the protective tube 6 is nested in the outer surface of the yarn bobbin 4, one side of the bearing group 7 is docked at the bottom side of the pad ring 5, one side of the damper 8 is docked at the side of the bearing group 7 away from the pad ring 5, the outer surface of the damper 8 is nested in the yarn can 3, and one end of the support frame 13 is fixed to the bottom end of the yarn can 3.
[0025] In this embodiment, the yarn feeding device is installed inside the yarn can 3 to realize close-range yarn delivery, greatly improving the timeliness and stability of yarn delivery, ensuring the coordinated operation of the entire yarn feeding system, and controlling the yarn transmission under the delivery of the working motor 14. At the same time, a corresponding pad ring 5 is provided at the bottom of the yarn tube 4. In this way, when the processed yarn 1 is output, the pad ring 5 will drive the bearing group 7 and the damper 8 to rotate, so that the yarn tube 4 can be output more smoothly, thereby improving its practicality in actual use. The protective tube 6 on the outer surface of the pad ring 5 further protects the yarn tube 4, so that its practicality in actual use is further improved.
[0026] Example 2
[0027] like Figure 1-2 As shown, a yarn feeding frame 2 is provided at one end of the processed yarn 1 away from the yarn bobbin 4, a yarn guide ring 9 is provided at one end of the yarn feeding frame 2, a front end tension controller 10 is provided at the bottom of the yarn guide ring 9 on the yarn feeding frame 2, a working motor 14 is provided on the yarn feeding frame 2, a yarn feeder 11 is provided at one end of the working motor 14, and a rear end tension controller 12 is provided at the bottom end of the yarn feeding frame 2;
[0028] One end of the yarn guide ring 9 is docked on the yarn feeding frame 2, one end of the front end tension controller 10 is docked on the yarn feeding frame 2, the outer surface of the working motor 14 is fixed on the yarn feeding frame 2, one end of the yarn guide 11 is docked on the working motor 14, and one side of the rear end tension controller 12 is docked on the bottom of the yarn feeding frame 2.
[0029] In this embodiment, the processed yarn 1, driven by the working motor 14, sequentially enters the yarn guide ring 9, the front tension controller 10, the yarn feeder 11, and the rear tension controller 12 from the front end. The yarn guide ring 9 prevents yarn deviation. Tension control plays a vital role in the yarn transportation process, which is directly related to the quality, production efficiency, and cost control of textiles. The addition of tension controllers at the front and rear ends can ensure uniform yarn stretching during processing. The automated tension control system of the working motor 14 can quickly respond to changes in yarn tension, reducing downtime and scrap rates caused by abnormal tension, and improving the continuity and efficiency of the production line.
[0030] Working principle:
[0031] like Figure 1-2As shown, the yarn feeding device is installed inside the yarn can 3, enabling close-range yarn delivery, significantly improving the timeliness and stability of yarn delivery, thereby ensuring the coordinated operation of the entire yarn feeding system. Driven by the working motor 14, the yarn transmission process is precisely controlled. At the same time, a pad ring 5 is provided at the bottom of the yarn bobbin 4. When the processed yarn 1 is output, the pad ring 5 drives the bearing group 7 and damper 8 to rotate together, thereby making the yarn output of the yarn bobbin 4 smoother and more stable, improving the operational stability and efficiency of the device in actual use.
[0032] In addition, the protective tube 6 on the outer surface of the pad ring 5 further provides protection for the yarn bobbin 4, preventing the external environment from interfering with the yarn transmission process, thereby further improving the durability and stability of the equipment in long-term use.
[0033] Driven by a working motor 14, the processed yarn 1 passes from the front end through a yarn guide ring 9, a front tension controller 10, a yarn feeder 11, and a rear tension controller 12. The design of the yarn guide ring 9 prevents the yarn from straying from its path, while the tension controller plays a crucial role in the yarn transport process, directly impacting the quality, efficiency, and cost control of textile production. The coordinated operation of the front and rear tension controllers ensures uniform yarn tension during processing, avoiding quality issues caused by uneven yarn tension.
[0034] The automated tension control system of the working motor 14 rapidly responds to changes in yarn tension, making real-time adjustments to minimize downtime and waste caused by tension anomalies, thereby improving the continuity and efficiency of the entire production line. This precise control ensures smooth yarn transport while effectively reducing waste and downtime, making the production process more efficient and controllable.
[0035] Through these optimized designs, the yarn feeding device not only improves the smoothness and system coordination of yarn delivery, but also improves the utilization efficiency of the device, ensuring the high efficiency and high quality of the textile production process.
[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
