Embodiment 1

[0041] Such as Figure 1-Figure 8 As shown, the weft insertion device of the special-shaped fabric loom includes a weft insertion mechanism 6, a side line mechanism 32, and a weft tensioning mechanism 4. The number of weft insertion mechanisms 6 is two, and each weft insertion mechanism 6 includes two weft insertion rods— - the first weft insertion rod 12 and the second weft insertion rod 13, the length of the first weft insertion rod 12 is greater than the second weft insertion rod 13, and the two weft insertion mechanisms 6 are respectively located on both sides of the woven fabric and along the woven fabric The center of the fabric is symmetrical in the length direction of the woven fabric.

[0042]By arranging two weft insertion rods at each weft insertion mechanism 6—the first weft insertion rod 12 and the second weft insertion rod 13, when weaving a fabric with a smaller length in the weft line 33 direction, a pair of first weft insertion rods 12 Carry out reciprocating...

Embodiment 2

[0060] Such as figure 1 As shown, this embodiment provides a special-shaped fabric loom, which is provided with any one of the weft insertion devices for the above-mentioned special-shaped fabric loom.

[0061] The special-shaped fabric loom has all the technical effects of the weft insertion device of the above-mentioned special-shaped fabric loom.

[0062] Specifically, this special-shaped fabric loom also includes a shed opening device 3, a weft beating device 7, a warp let-off device, a fabric clamping device 8 and a crimping device 10, taking the upstream to downstream of fabric production as the direction of description, wherein The warp thread 5 is tensioned and arranged between the warp let-off creel 1 and the heald lifting shed device 3, the heald lifting shedding device 3 is set between the beating device 7 and the warp thread tensioning device 2, and the weft beating device 7 is arranged on the heald lifting shedding device 3 And between the weft insertion mechanis...

Abstract

The invention relates to the technical field of looms, in particular to a weft insertion device of a special-shaped fabric loom and the special-shaped fabric loom provided with the weft insertion device. The weft insertion device of the special-shaped fabric loom comprises two weft insertion mechanisms, wherein each weft insertion mechanism comprises two weft insertion rods, namely, a first weft insertion rod and a second weft insertion rod, the first weft insertion rod is longer than the second weft insertion rod, and the two weft insertion mechanisms are located on two sides of woven fabricrespectively and are symmetrical in the length direction of the woven fabric along the center of the woven fabric. The technical problem that three-dimensional special-shaped fabric cannot be woven inthe prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of looms, in particular to a weft insertion device for a special-shaped fabric loom and a special-shaped fabric loom with the weft insertion device for a special-shaped fabric loom. Background technique [0002] Chinese patent document CN105568513B (disclosure date 2017.05.24) discloses a three-dimensional loom weaving mechanism, including a hedging shedding device, a weft insertion device, a weft sliding device, a weft fixing device and a weft beating device. The warp thread opening is realized by interlacing different heald frames up and down. The weft insertion device moves the weft thread forward through the weft insertion rod and the weft insertion hook to pass through the warp thread opening. The weft thread sliding device and weft thread fixing device pull the weft thread after passing through the warp thread opening. For subsequent weaving and tightening, the weft beating device tightens the weft and...
