Description

Technical Field

[0001] The utility model relates to the field of textile mechanical devices, in particular to a two-for-one twisting device. Background Art

[0002] In the textile industry, the two-for-one twister is a key equipment for producing high-quality yarn. Its performance stability and efficiency directly affect the quality of the yarn and production efficiency. However, the traditional two-for-one twister has a series of technical difficulties in yarn guidance and winding, which limits the application and development of the two-for-one twister in the textile industry.

[0003] First of all, yarn guidance is an important part of the working process of the two-for-one twister. Traditional two-for-one twisters often use a simple guiding structure for yarn guidance, which often cannot adapt well to the dynamic changes of the yarn during the twisting process, causing the yarn to easily deviate or even break, seriously affecting the twisting efficiency and quality of the yarn.

[0004] Secondly, winding is another important part of the two-for-one twister. Traditional two-for-one twisters often use fixed winding speed and tension, which cannot be flexibly adjusted according to the specifications and types of yarns. This winding method often leads to uneven winding of the yarn, and even looseness, wrinkling and other problems, further reducing the quality of the yarn. Utility Model Content

[0055] A pulley 18 is installed around the side of the rotating table 2 to help reduce friction and resistance during rotation and improve the stability of rotation.

[0056] Guide device

[0057] The telescopic motor 12 at the end of the guide rod 5 can adjust the length of the output of the telescopic motor 12 as needed, thereby adjusting the position of the guide wheel 14 to apply a certain tension to the yarn to ensure the correct guidance of the yarn during the twisting process.

[0058] Both ends of the guide wheel 14 are rotatably mounted on the articulated frame 13 , and the yarn is guided from the unwinding shaft 3 to the winding device through the output of the telescopic motor 12 and the rotation of the guide wheel 14 .

[0059] The guide frame 6 is designed as a truncated cone structure, which can better disperse the tension of the yarn, reduce the wear and breakage of the yarn, and at the same time guide the yarn, so that multiple strands of yarn can be aggregated and twisted together.

[0060] Winding device

[0061] The winding device comprises a winding frame 8, a winding shaft 10 and a winding motor 9. The winding motor 9 drives the winding shaft 10 to rotate through the winding frame 8 to achieve the winding of the yarn.

[0062] The winding motor 9 can adjust the winding speed and tension according to the specifications and types of the yarn to ensure the uniformity and stability of the yarn winding.

[0065] Rack 1 structure

[0066] The rack 1 adopts an L-shaped structure, which provides stable support and installation space, making the overall structure of the equipment compact and stable.

[0067] The utility model realizes efficient double twisting of yarn through a series of well-designed parts working together. The following is a detailed summary of its working principle:

[0068] Equipment layout:

[0069] The equipment is mainly composed of a frame 1, a winding device, a driving device 7, a rotating table 2 and a guiding device.

[0070] The rack 1 provides a stable basic support for the entire device.

[0071] The winding device is installed at the upper end of the frame 1 and is used to collect the twisted yarn.

[0072] Yarn placement and lead-out:

[0073] The yarn is placed on a reel 3 which is arranged around a rotating table 2.

[0074] During the two-for-one twisting process, the yarn is drawn out from the unwinding shaft 3, passes through the guide device, and finally reaches the winding device for collection.

[0075] Rotating table 2 and driving device 7:

[0076] The rotating table 2 is installed at the output end of the driving device 7 and is driven to rotate by the driving device 7 (such as a servo motor).

[0077] The rotation speed and direction of the rotary table 2 are precisely controlled by the driving device 7, thereby controlling the twisting speed and direction of the yarn.

[0078] Guide device:

[0079] The guide device is a key part of the equipment, and is composed of a guide column 4, a guide rod 5, a guide wheel 14, a guide frame 6 and a limiting roller 17.

[0080] The guide column 4 is located in the middle of the rotating table 2, and a guide rod 5 is arranged around the top thereof, and a guide wheel 14 is arranged on the guide rod 5. The guide wheel 14 is used to guide the yarn to move along a specific path to ensure the stability and consistency of the yarn during the twisting process.

[0081] The guide frame 6 is located at the top of the guide column 4, and its outer wall is surrounded by a guide groove 15 and a limiting roller 17. When the yarn passes through the guide groove 15, it is limited by the limiting roller 17 to prevent the yarn from deflecting or winding.

[0082] Rolling process:

[0083] After being guided by the guide device, the yarn reaches the winding device.

[0084] The winding device collects the yarn according to the set parameters (such as winding speed, tension, etc.) to form a double-twisted yarn roll.

[0085] Optimization features:

[0086] A plurality of unwinding shafts 3 are arranged around the rotating table 2, so that a plurality of yarns can be twisted for two times at the same time, thereby improving production efficiency.

[0087] The guide device is carefully designed to ensure the stability and consistency of the yarn during twisting.

[0088] The driving device 7 accurately controls the rotation speed and direction of the rotary table 2 to meet the requirements of doubling of yarns of different specifications and types.

[0089] In summary, the double twisting device drives the rotating table 2 to rotate through the driving device 7, uses the guide device to guide the yarn to be twisted, and collects the double twisted yarn through the winding device, thereby achieving efficient double twisting of the yarn.
