Problems solved by technology

Since the secondary main nozzle is fixed, the nozzle of the secondary main nozzle that cannot swing with the sley will consume a large part of the energy of the compressed gas during the weft insertion process, which will affect the weft insertion rate of weaving, which is not good. Fully adapt to the needs of the development of air-jet looms in terms of high speed and wide width

Embodiment Construction

[0013] to combine figure 1 and figure 2 , an air-jet loom double-oscillating main spray weft insertion mechanism, comprising a primary main spray 1 and a secondary main spray 2, the primary main spray is arranged on a button seat 3, and it has two nozzles 101, 102, and the secondary main spray Spray is also arranged on the buckle seat 3, and it also has two nozzles 201,202, the above-mentioned first-level main spray 1 position is in the front, the second-level main spray 2 position is behind, the nozzle 201 of the second-level main spray 2 and the first-level main spray The nozzle 101 of 1 is aligned, that is, the nozzle 201 is directly facing the nozzle 101, and the nozzle 202 of the secondary main spray 2 is aligned with the nozzle 102 of the primary main spray 1, that is, the nozzle 202 is directly facing the nozzle 102. The main spray 2 swings synchronously with the buckle seat 3. The above-mentioned buckle seat 3 is provided with a front buckle seat foot 4 and a rear b...

Abstract

The invention discloses a double-swing main jet wefting insertion mechanism of a jet loom, comprising a fist-level main jet and a second-level main jet. The double-swing main jet wefting insertion mechanism of a jet loom is characterized in that the first-level main jet and the second-level main jet are arranged on the same buckle seat and synchronously swing with the buckle seat, the first-level main jet is arranged in front of the second-level main jet, and the nozzle of the second-level main jet is aligned with the nozzle of the first-level main jet one by one. In the invention, the fist-level main jet performs the main dragging action on weft yarn, the second-level main jet is the supplement of the fist-level main jet, and the second-level main jet and the first-level main jet are arranged on the same buckle seat and synchronously swing, which not only can obtain large enough traction to provide enough time for the weft yarn to fly but also can cause the weft yarn to fly along a straight line so as to reduce unnecessary bending resistance, and thus the weft yarn can smoothly fly. The invention lowers gas consumption, and can better improve wefting insertion rate to obtain the effect of energy saving and high efficiency. Meanwhile, the invention can better adapt to the requirements of high speed and wide width of jet looms.

Description

technical field [0001] The invention relates to an air-jet loom, in particular to a weft insertion mechanism of the air-jet loom. Background technique [0002] In the air-jet loom of the prior art, in the weaving process, the main nozzle part of the weft insertion mechanism is realized by combining the first-level main nozzle and the second-level main nozzle, that is, a group of secondary main nozzles (auxiliary nozzles) fixed on the frame main jet) and a group of primary main jets that swing with the sley. Since the secondary main nozzle is fixed, the nozzle of the secondary main nozzle that cannot swing with the sley will consume a large part of the energy of the compressed gas during the weft insertion process, which will affect the weft insertion rate of weaving, which is not good. It can fully meet the needs of the development of air-jet looms in terms of high speed and wide width. Contents of the invention [0003] The task of the present invention is to solve the ...
