Description

Technical Field

[0001] The utility model relates to the technical field of yarn processing, in particular to a yarn rack with a yarn traction structure. Background Art

[0002] Patent document CN220723102U discloses a textile yarn rack, belonging to the textile field. A textile yarn rack includes a main bracket and a sub-bracket arranged on one side of the main bracket. A spacing adjusting member is arranged between the main bracket and the sub-bracket. A plurality of annular seats are fixedly connected to the sub-bracket. A rotating cylinder is rotatably connected to each of the plurality of annular seats. A plurality of guiding grooves are formed on the circumferential side of the rotating cylinder. A convex block is slidably connected inside the guiding groove. A state switching member extending into the rotating cylinder is arranged on the main bracket. When the sub-bracket moves away from the main bracket, the state switching member contracts the convex block into the inside of the rotating cylinder. When the sub-bracket moves towards the main bracket, the state switching member pushes the convex block to the outside of the rotating cylinder. It can achieve locking and unlocking of a plurality of yarn bobbins in batches, quickly complete the installation and disassembly of a plurality of yarn bobbins, and improve work efficiency.

[0003] However, the yarn rack does not have a tensioning component, and the tension of the yarn cannot be adjusted in time. When the yarn is too tight, the yarn will break. When the yarn is too loose, the quality of the finished fabric will be affected. At the same time, in order to adapt to larger yarn bobbins, the existing brackets are set to be longer. When using smaller yarn bobbins, the extra brackets will increase the risk of yarn entanglement. Therefore, it is necessary to improve such a structure to overcome the above defects.
