Embodiment 1

[0021] like figure 1 As shown, the air-jet weft insertion tension adjustment device for simultaneous introduction of multiple weft yarns according to the present invention includes a bolt 1, a nut 2, a spring 3, a first tension piece 4, a second tension piece 5, a yarn guide hole 6 and a platform base 11.

[0022] The bolt 1 is vertically fixed on one end of the base 11 platform, and the bolt 1 is provided with a nut 2 to cooperate with the bolt 1; one end of the spring 3 is fixed to the nut 2, and the other end is fixed to the first tension piece 4; the second tension piece 5 is connected to the first tension piece. The sheet 4 is opposite and arranged on the bolt 1 , the distance between the second tension sheet 5 and the base 11 is smaller than the distance between the first tension sheet 4 and the base 11 . Four yarn guide holes are equidistantly arranged on the base 11 platform.

[0023] The yarn 7 is located between the first tension sheet 4 and the second tension shee...

Embodiment 2

[0027] In the high-speed two-jet air-jet loom, the first weft feeder introduces a polyester low-elasticity yarn (DTY low-elasticity yarn), and the second weft feeder introduces three DTY low-elasticity yarns, and each DTY low-elasticity yarn passes through the Tension adjustment device for tension adjustment. The warp yarns are made of rayon, 30 per cycle, and the drawing-in sequence is: 1.1.1.2.2.2.3.4.5.5.6.1.1.1.2.2.2.3.4.5.6.6.6.6.1.2.2.2.3.4. The weft yarns are cardboard method. A: 1.3.5; A: 2.4.6; A 1.3.5; B 2.4.6; A 1.3.5; B 2.4.6; .6; A 1.3.5; B 2.4.6; A 1.3.5; A: 2.4.6; B 1.3.5; The tissue diagram of weaving rayon plaid fabric is as follows figure 2 .

[0028] figure 2 The shown weave needs 34 picks in the common air-jet loom weft insertion mode, but only 18 picks are needed after using the tension adjustment device and method of the present invention. It not only improves the weaving efficiency, but also saves energy.

Embodiment 3

[0030] High-speed four-jet air-jet loom, A weft feeder introduces a DTY low elastic yarn; B weft feeder introduces three weft yarns, which are linen yarn, cotton yarn and viscose yarn; C weft feeder introduces a cotton yarn ; The small weft feeder introduces three weft yarns, which are FDY filament, Tencel and nylon filament. Every weft yarn is tension adjusted by the tension adjustment device of the present invention. The four weft feeders can store 8 different weft yarns in total, which is twice that of ordinary air-jet looms of the same kind, greatly increasing the diversity of raw materials or designs.

Abstract

The invention relates to a pneumatic picking tension regulating device for simultaneously leading in multiple roots of weft, comprising a base with a platform, a weft guide hole, bolts, nuts, springs, a first tension sheet and a second tension sheet. The device achieves the purpose of regulating the pneumatic picking tension force. Each tension device is used for regulating the tension force of one root of weft; after the tension force is regulated by the tension device, multiple roots of wefts which are made of different raw materials and are of different qualities can be simultaneously led into a weft storage and then be sprayed out from a same spray nozzle, thereby respectively reducing the working frequency of the spray nozzle, the shedding frequency and the energy consumption of an air-jet loom.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a tension regulating device. By adjusting the tension of weft yarns through the device, multiple weft yarns can be simultaneously fed into a main nozzle and introduced into a shed simultaneously. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft through the shed. Its working principle is to use air as the weft insertion medium, and use the jetted compressed air to generate friction and traction on the weft yarn, and bring the weft yarn through the shed to achieve the purpose of weft insertion. This weft insertion method enables the loom to achieve high speed and high production. Among several shuttleless looms, the air-jet loom is the one with the highest speed. Due to the reasonable weft insertion method, high weft insertion rate, easy and safe operation, wide variety adaptability, low machine material consumption and high efficiency ...
