Description

Technical Field

[0004] When the existing shuttle works in the circular loom, the weft yarn tube moves along the axial direction. When the weft yarn tube moves too much, it is easy to cause inaccurate weft insertion and increase the risk of weft loss. Summary of the invention

[0007] By adopting the above technical scheme, before the weft yarn tube and the shuttle are disassembled or assembled, the positioning of the mounting rod by the positioning piece is first released, and then the mounting rod is driven to move in a direction away from the central axis of the base plate, so that the clamping piece moves axially along the support rod without being limited by the mounting rod, which facilitates the removal of the weft yarn tube from between the two clamping pieces or the installation of the weft yarn tube between the two clamping pieces; after the weft yarn tube is installed on the shuttle, the mounting rod is driven to move in the direction of the central axis of the base plate, and the positioning piece positions the mounting rod so that the positioning piece is on the moving path of the clamping piece, thereby limiting the axial movement range of the weft yarn tube, improving the stability and accuracy of the weft insertion process, and reducing the probability of weft falling off.

[0008] Optionally, an operating groove connected to the mounting hole is formed on the end surface of the mounting seat away from the support seat, and the positioning member includes a locking spring and an operating rod arranged in the operating groove, and an operating block located below the mounting rod is provided on the side of the operating rod facing the bottom wall of the operating groove, and a clamping block is provided on the end surface of the operating block facing the mounting rod, the mounting rod is located on the moving path of the clamping block along the axis direction of the operating rod, and a clamping groove for inserting the clamping block is formed on the end surface of the mounting rod facing the support seat, and the locking spring is in a compressed state, one end of the locking spring abuts against the bottom wall of the operating groove, and the other end of the locking spring abuts against the operating rod.

[0009] By adopting the above technical solution, in the process of driving the mounting rod to move in the direction of the central axis of the base plate, when the slot is aligned with the block, the locking spring drives the operating rod to move and inserts the block into the slot, thereby locking the mounting rod and the mounting seat, making it difficult for the mounting rod to move along the axis of the mounting hole; when the shuttle is working, the axial movement of the weft yarn tube will be limited by the mounting rod, that is, the axial movement range of the weft yarn tube is limited.

[0010] Optionally, a limit block is provided on the side of the mounting rod, and the limit block is located on a side of the mounting seat away from the central axis of the base plate.

At this time, the driving rod 314 is inserted into the giving way groove 512, and the clamping plate 321 is not subjected to the force of the clamping spring 331, so that the staff can replace the weft yarn tube conveniently. In the fourth step, after the staff replaces the weft yarn tube, the driving sleeve 323 and the round tube 51 are rotated, the round tube 51 conflicts with the second chamfered inclined surface, the round tube 51 drives the positioning block 52 to disengage from the positioning hole 511, and the clamping spring 331 resets to drive the sleeve 323 to reset. At the same time, the round tube 51 drives the driving rod 314, the round rod 631 and the gear 632 to rotate, and the gear 632 drives the rack 633, the connecting rod 634 and the locking block 62 to move, so that the locking block 62 disengages from the slot 422, and the locking block 62 releases the lock on the mounting rod 42, and the push spring 416 resets to drive the slider 415 and the mounting rod 42 to move until the block 433 is aligned with the slot 421, and the locking spring 434 drives the operating rod 431 to move, and reinserts the block 433 into the slot 421, so that the block 433 limits the mounting rod 42.
