Description

Technical Field

[0001] The utility model relates to a circular loom, in particular to a shuttle of a circular loom facilitating the replacement of a weft yarn bobbin. Background Art

[0002] A circular loom refers to an industrial device for weaving tubular fabrics. In an existing plastic circular loom, a roller assembly is arranged between an upper apron and a lower apron to form a rolling track for the shuttle to run. The function of the shuttle in the plastic circular loom is to thread weft yarns, which is an important component of the circular loom. Weft yarns are usually arranged on a shuttle board of the existing circular loom. The weft yarns are wound on a bobbin tube and then fixed on a tube seat of the shuttle. When the weft yarns on the bobbin tube are exhausted, the machine stops to replace the weft yarn. Previously, due to the slow speed of the machine, the small amount of weft yarns wound on the bobbin tube could meet the production requirements. Therefore, the bobbin tube could be directly snapped into the tube seat with one hand (usually one hand slightly retracts the tube seat, and the other hand quickly snaps the bobbin tube into the tube seat). With the increase in the production speed of the machine, in order to avoid frequently opening and closing the machine to replace the weft yarn, the amount of weft yarns wound on the bobbin tube is increasing, the overall volume is getting larger, and the weight is also getting heavier. Therefore, the existing bobbin tube is time-consuming and laborious to install, and usually requires the cooperation of multiple people to complete. Summary of the Utility Model

[0030] The driving member 7 is connected to the transmission member 6 and drives the first support shaft 5 to axially slide through the transmission member 6. The beneficial effects of the present utility model are that a driving member and a transmission member are provided. Through the cooperation of the driving member and the transmission member, the first tube seat moves relative to the second tube seat, increasing the installation space, facilitating the quick and convenient installation of the weft yarn bobbin. The structure is simple, the operation is convenient and labor-saving, and it is convenient to take and place the weft yarn bobbin. The present utility model also has the advantages of simple structure, convenient assembly, reliable action, and long service life.

[0031] The present utility model further includes an elastic member 51 sleeved outside the first support shaft 5; the elastic member 51 abuts against the mounting seat 4 and has a tendency to drive the first tube seat 2 to approach the second tube seat 3. The mounting seat 4 is arranged on the shuttle plate 1 through the cooperation of a sliding block 41 and a sliding groove 13. The setting of the elastic member provides a reset force, so that the weft yarn bobbin will not shift during use. When installing, slightly changing the position of the driving member can reset the first tube seat, which is time-saving and labor-saving and convenient for disassembling and assembling the weft yarn bobbin. The setting of the sliding block and the sliding groove is convenient for installation and the structure is simple.

[0032] The present utility model further includes a mounting plate 12. The driving member 7 is hinged to the mounting plate 12.
