Description

A kind of strand knits the water jet looms of mode
Technical field
The utility model relates to a kind of water jet looms, particularly relates to the water jet looms that a kind of strand knits mode.
Background technology
Loom mainly through opening, wefting insertion, beat up, batch, with operations such as the warp let-offs, warp thread and weft yarn are staggered to form fabric, different fabrics has different graticule intertexture rules.The process of opening operation is roughly: warp thread passes from the middle through-hole of heald respectively, and along with heald move up and down be divided into two-layer up and down, form a spatial channel passed through for weft insertion device, i.e. shed open, after parallel to be introduced, make part or all of levels warp interlock up and down again, to be woven into required fabric with parallel, and form new shed open.The shedding mechanism of existing water jet looms is that loom main shaft often returns and circles mostly, and warp thread forms a shed open, cannot meet strand at a high speed and knit the demand of opening.
In addition, existing water jet looms mostly adopts the weaving method of fabrics in general to weave silk screen, this weaving mode, and formed at warp thread in the process of shed open and warp thread can not be made to be wound around, therefore can not realize strand and knit, the screen fabric quality of knitting is low, intensity is also poor.At present, also have the water jet looms of only a few can be formed at warp thread to realize strand in the process of shed open and knit, but the opening strand loom structure that it uses is unreasonable, mainly actuating unit aspect Shortcomings, namely in heald frame, the transverse reciprocating of leno heald reed moves is that the cam that vertically moves of dependence one and back-moving spring have been worked in coordination with, its structure is comparatively complicated, runs steady not.Patent CN202247138U discloses a kind of opening cross-weaving mechanism for plastic silk screen knitting machine, and it comprises the heald frame that can longitudinally move back and forth, and be arranged in heald frame can the leno heald reed of transverse reciprocating movement, and leno heald reed is configured with strand and knits actuating unit; Above-mentioned strand is knitted actuating unit and is comprised cam mechanism and corresponding rocker arm connecting rod assembly, and cam mechanism drives leno heald reed transverse reciprocating to move by rocker arm connecting rod assembly; Above-mentioned rocker arm connecting rod assembly comprises vertical rocking bar, L shape rocking bar and inverted L-shaped rocking bar, the lower end of vertical rocking bar is provided with jointed shaft, the top one of vertical rocking bar is hinged with leno heald reed, two is be connected by the vertical rod section of connecting rod with L shape rocking bar, the drift angle place of L shape rocking bar is provided with jointed shaft, the rail segment of L shape rocking bar and the rail segment of inverted L-shaped rocking bar hinged, the drift angle place of inverted L-shaped rocking bar is provided with jointed shaft, and the vertical rod section of inverted L-shaped rocking bar is connected with the cam in cam mechanism by cam link.This patent drives leno heald reed transverse reciprocating to move by cam mechanism and rocker arm connecting rod assembly, larger shock and vibration can be caused because of gap in the process run up, if things go on like this, larger shock and vibration wearing and tearing can be brought to cam mechanism especially rocker arm connecting rod assembly, thus reduce the service life of equipment, add the production cost of enterprise.
