Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a shaft frame needle threading mechanism. Background Art

[0002] In the textile industry, especially in processes such as weaving, embroidery, and sewing, it is often necessary to pass yarn or fiber threads through a series of complexly arranged quill holes. Traditional methods mainly rely on manual operation, which is not only inefficient but also prone to inaccurate threading due to human factors, affecting the smooth progress of subsequent processes and the quality of the final product. With the development of automation technology, the development of a quill needle threading mechanism is particularly important.

[0003] The reference announcement number CN216287772U is an automatic wire threading device, which includes a wire feeder and at least one corrugated tube holder arranged in sequence, characterized in that the wire feeder includes an upper wire feed wheel and a lower wire feed wheel arranged above and below, with parallel axes, and a wire feeding groove for accommodating the wire harness is provided at circumferentially opposite positions of the upper wire feed wheel and the lower wire feed wheel; a through groove for accommodating the corrugated tube is provided on the corrugated tube holder, and the axis of the wire feeding groove coincides with the axis of the through groove. An automatic wire threading device is used to directly pass the wire harness with a guide head at the front end through a longer closed corrugated tube without damaging the wire harness and the closed corrugated tube. The processing is convenient and fast, ensuring the efficiency of wire harness threading, saving time and improving the processing yield. According to the above, although the device can be well applied, it is usually not convenient to perform multi-station threading operations on the workpiece to be threaded in sequence, making it difficult for the device to achieve the established expectations for the threading efficiency of the object, which often troubles users.
