Embodiment 1

[0024] Embodiment 1: T-shaped grooves are opened on the holding device 7 and the clamping block 2, and the material is hard plastic. Shuttle 6 backs are made T-shaped projection. The T-shaped groove of the holding device 7 and the T-shaped protrusion on the back of the shuttle 6 are in a loose fit relationship at the beginning of insertion, and a tight fit relationship at the end of the insertion; the T-shaped groove of the clamping block 2 and the T-shaped protrusion on the back of the shuttle 6 The bump is a loose fit. The pin 11 on the movable bayonet 1 is a circular metal rod, which utilizes the electromagnetic principle to control expansion and contraction.

Embodiment 2

[0025] Embodiment 2: Dovetail grooves are opened on the holding device 7 and the clamping block 2, and the material is metal. Shuttle 6 backs are made dovetail protrusion. The dovetail groove of the holding device 7 and the dovetail protrusion on the back of the shuttle 6 are in a loose fitting relationship at the beginning of insertion, and are in a tight fitting relationship when the insertion ends; cooperation relationship. The pin 11 above the movable bayonet pin 1 is a circular metal rod, which utilizes the pneumatic principle to control expansion and contraction.

Abstract

The invention relates to a rigid rod gripper lead-in continuous yarn filling device, comprising loom, rigid rod gripper, handler, receiver, and shuttle, characterized in that: the handler is fixed on the rigid rod gripper at one side of loom; the receiver is formed by handle block and movable bayonet lock at another side of loom; via the alternating motion of rigid rod gripper, the shuttle is alternatively stopped in handle position and receiver. The invention has the advantages that: it realizes lead-in continuous yarn filling on rigid rod gripper loom, to automatically weave tubular fabric on high-accuracy rigid rod gripper loom.

Description

technical field [0001] The invention belongs to the textile field, and relates to an automatic weft insertion mechanism for weaving tubular fabrics by introducing continuous weft yarns on a rigid rapier loom. Background technique [0002] The weaving of fine, ultra-high-density tubular fabrics requires both continuous weft yarns and high precision of the loom. On the shuttle loom, the weft yarn introduced can be continuously inserted through the reciprocating insertion of the shuttle in the shed opening, but the precision of the loom is low, and fine, extra-high-density weaving cannot be performed. When weaving on a rigid rapier loom, the weft yarn needs to be cut after the weft yarn is inserted once by the weft insertion system, so tubular fabrics cannot be made. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic weft insertion mechanism for introducing continuous weft yarns to weave tubular fabrics o...
