TECHNICAL FIELD
[0001] The application relates to a filament feeding device with a broken filament function and relates to the technical field of spinning. BACKGROUND
[0002] The rotor spinning composite yarn technology integrates the excellent wearability of short fibers and the functionality of filaments, and is one of the key development directions of rotor spinning. By adding a new device to the rotor spinning machine, a product with structural differentiation is developed; the rotor spinning composite yarn has the characteristics of high strength, good evenness, stable and diversified structure, and less hair, and has a broad market prospect. Therefore, if the transformation can be realized on most rotor spinning machines and industrialization is realized at the same time, the output of the composite yarn will be greatly improved, and the market demand will be met. However, the technology of transforming the rotor spinning machine into a rotor composite spinning machine still has defects, for example, the investment cost of the rotor composite spinning equipment is high; the filament feeding device is designed unreasonably, the operator has difficulty in operation, and the normal spinning is affected; during the spinning process, the filament is still continuously fed when the short fiber yarn breaks, forming waste yarn, and the naked filament needs to be rewound and cut off when the joint is reconnected, which wastes manpower and material resources and reduces the production efficiency.
[0003] In order to solve the above problems, the Chinese patent with the publication number CN211227567U discloses a fixed composite braided material pay-off device, which comprises 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. According to the need, movable plates are arranged on the corresponding layer frames, and movable connecting conical guide columns are arranged on the movable plates, so as to facilitate the placement of the coils and the joint use of multiple coils to form a composite braided material. However, the device occupies a large space, and is a fixed device with poor flexibility, which is not suitable for use on the rotor spinning machine with limited space position.
[0004] In order to solve the problem of operation difficulty caused by unreasonable design of the device, the Chinese patent with the publication number CN221662237U discloses a pay-off device for vortex spinning machine, which is characterized in that a pay-off shaft is rotatably installed on a sliding seat frame, so that the tightness between the spinning can be manually adjusted. Although the device increases the sliding seat 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 process.
[0005] A full-automatic intelligent control method and system for wrap yarn of rotor spinning are disclosed in Chinese patent CN113652774A. The wrap yarn is spun by the spinning unit of the rotor spinning machine combined with the external feeding mechanism, and the yarn breakage and joint are realized by the controller, providing a full-automatic intelligent control scheme for the production of wrap yarn of rotor spinning. However, no specific device is designed. In addition, Chinese patent CN114381833A discloses a linkage control system, control method and control device in the process of yarn forming. Although the process of forming filament staple yarn of rotor spinning is proposed, only the process design is provided without specific industrial facilities. SUMMARY

[0032] The long filament bobbin positioning ring bracket 11 has two long filament bobbin trays 12 and two long filament bobbin positioning rings 3 at both ends. The long filament bobbin positioning rings 3 are located above the long filament bobbin trays 12 and are used to fix the long filament bobbin.
[0033] The first support body 10 is provided with a first lead wire support 6 and a second lead wire support 7 respectively;
[0034] Both ends of the first lead wire support 6 are equipped with ceramic guide coils 1;
