Description

Technical Field

[0001] The present application relates to a filament feeding device with a filament breaking function, and relates to the technical field of spinning. Background Art

[0002] The rotor spinning composite yarn technology combines the excellent wearability of short fibers and the functionality of filaments, and is one of the key development directions of rotor spinning. By adding new devices to the rotor spinning machine, products with structural differentiation are developed; rotor spinning composite yarn has the characteristics of high strength, good yarn uniformity, stable and diversified structure, less hairiness, etc., and has broad market prospects. Therefore, if the transformation can be achieved on most rotor spinning machines and industrialized at the same time, the output of composite yarn will be greatly increased to meet market demand. However, there are still deficiencies in the technology of transforming rotor spinning machines into rotor composite spinning, such as the high investment cost of rotor composite spinning equipment; the filament feeding device is unreasonable in design, and the operator is difficult to operate, which affects normal spinning; when the staple yarn breaks during the spinning process, the filament is still continuously fed, forming waste yarn. When re-joining, the bare yarn needs to be unwound and cut off, which wastes manpower and material resources and reduces production efficiency.

[0003] To solve the above problems, a Chinese patent with the announcement number CN211227567U discloses a fixed composite braided material pay-off device, including a frame body, and the frame body is provided with a first layer frame, a second layer frame and a third layer frame from bottom to top, and a movable plate is provided on the corresponding layer frame as needed, and a movably connected conical guide column is provided on the movable plate, which is convenient for placing coils and for combining multiple coils to form composite braided materials. However, the device occupies a large space and is a fixed device with poor flexibility, and is not suitable for use on a rotor spinning machine with limited space.

[0004] In order to solve the problem of difficult operation caused by unreasonable device design, the Chinese patent with announcement number CN221662237U discloses a pay-off device for vortex spinning machine, which can manually adjust the tightness between spinning by rotating the pay-off shaft on the sliding frame. Although the device adds a sliding frame, which facilitates the operation to a certain extent, the device occupies a large space, and the operator still needs to spend a lot of time and energy during the operation.

[0005] The Chinese patent with publication number CN113652774A discloses a fully automatic intelligent control method and system for rotor spinning wrapped yarn. The wrapped yarn is spun by combining the spinning unit of the rotor spinning machine with an external feeding mechanism, and the yarn breaking and jointing are achieved through the controller, providing a fully automatic intelligent control solution for the production of rotor spinning wrapped yarn; however, no specific device is designed. In addition, the Chinese patent with publication number CN114381833A discloses a linkage control system, control method and control device in the yarn spinning process. Although the spinning process of rotor spinning filament staple fibers is proposed, it is only a process design without specific industrial facilities. Summary of the invention
