The utility model relates to a kind of air-jet loom and returns comprehensive formula shedding mechanism, comprises cam, rotor, heald frame, and the outside correspondence of every sheet heald frame arranges a shedding cam, described cam and rotor contact, and rotor exterior arranges harness lever; Harness lever is connected with harness lever skate, and described harness lever skate connects with the steel wire rope I be connected on heald frame and edge under pulling heald frame, along being connected on the arc surface inside jack stick by steel wire rope II on heald frame; The outside of jack stick connects some return springs; Each jack stick arc surface of described heald frame both sides arranges a fixed mount and load a horizontal pin between two fixed mounts; A mark post is penetrated in the hole at this horizontal pin center.The utility model beneficial effect is: when the upper and lower action of heald frame, can guarantee that heald frame keeps upper and lower vertical motion and reduces left and right swing, is conducive to making heald frame return back to top position, manufactures handling ease, is convenient to observation place change.
Description
Technical field
The utility model relates to air-jet loom technology, particularly relates to a kind of air-jet loom and returns comprehensive formula shedding mechanism.
Background technology
Air-jet loom is the shuttleless loom adopting jet-stream wind weft traction to pass through shed open, operation principle utilizes air as wefting insertion medium, produce frictional traction with the compressed air stream ejected to weft yarn to draw, weft tapes is crossed shed open, is reached the object of wefting insertion by the jet of jet generation.This filling insertion way can make loom realize high speed high yield; In several shuttleless loom, air-jet loom is the one that the speed of a motor vehicle is the highest, because filling insertion way is reasonable, enter latitude rate higher, running operation handy and safe, has varietal adaptation wider, machine material consumption is few, the advantages such as efficiency is high, and the speed of a motor vehicle is high, noise is low, have become one of Novel cloth machine of most development prospect.
The shedding mechanism that air-jet loom is conventional has crank, cam, multi-arm three types.In recent years, along with the development of electronic technology and market are to the demand of high-quality fabric, there is the polytype such as electronics opening, electronic jacquard opening; It is jet that to knit mechanical type dobby shedding, electronic dobby opening that stool adopts identical with Rapier looms with electronic jacquard shedding mechanism.
But, existing time comprehensive formula cam shedding mechanism, heald frame steel wire rope is connected with jack stick, when carrying out the upper and lower elastic operation of several heald frames, because elastic force effect often carries out generation left and right sidesing shifting, cannot guarantee like this to pull vertically, can affect to processing, also be not easy to position in time or safeguard.Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model provides a kind of and is conducive to making heald frame return back to top position, can guarantee heald frame knee-action, manufacture handling ease, be convenient to the air-jet loom of observation place change returns comprehensive formula shedding mechanism, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of air-jet loom returns comprehensive formula shedding mechanism, comprises cam, rotor, heald frame, and the outside correspondence of every sheet heald frame arranges a shedding cam, described cam and rotor contact, and rotor exterior arranges harness lever;
Harness lever is connected with harness lever skate, and described harness lever skate connects with the steel wire rope I be connected on heald frame and edge under pulling heald frame, along being connected on the arc surface inside jack stick by steel wire rope II on heald frame;
The outside of jack stick connects some return springs;
Each jack stick arc surface of described heald frame both sides arranges a fixed mount and load a horizontal pin between two fixed mounts;
A mark post is penetrated in the hole at this horizontal pin center.
Correspondingly, when cam radius large by small radius steering, rotor is depressed, makes harness lever turn over certain angle clockwise;
When heald frame declines, return spring is stretched, stored energy; When cam is turned to minor radius by large radius, spring releases energy, and makes heald frame return back to top position.
The beneficial effect that air-jet loom described in the utility model returns comprehensive formula shedding mechanism is:
(1) by arranging a fixed mount and load a horizontal pin on each jack stick of heald frame both sides between two fixed mounts, then, a mark post is penetrated in the hole at this horizontal pin center, when the upper and lower action of heald frame, can guarantee that heald frame keeps upper and lower vertical motion and reduces left and right swing, be conducive to making heald frame return back to top position, manufacture handling ease, be convenient to observation place change;
(2) can be specifically designed to and weave plain cloth, have structure simple, adapt to feature at a high speed, and manufacture processing easily, cost is lower.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation that air-jet loom described in the utility model embodiment returns comprehensive formula shedding mechanism.
In figure:
1, cam; 2, rotor; 3, harness lever; 4, harness lever skate; 5, steel wire rope I; 6, heald frame; 7, steel wire rope II; 8, jack stick; 9, return spring; 10, fixed mount; 11, horizontal pin; 12, mark post.
Detailed description of the invention
As shown in Figure 1, air-jet loom described in the utility model embodiment returns comprehensive formula shedding mechanism, comprises cam 1, rotor 2, heald frame 6, and the outside correspondence of every sheet heald frame 6 arranges a shedding cam 1, cam box is installed on the outside of loom side, forms outboard cam shedding mechanism; Described cam 1 contacts with rotor 2, rotor 2 outer setting harness lever 3, when cam 1 radius large by small radius steering, rotor 2 is depressed, harness lever 3 is made to turn over certain angle clockwise, harness lever 3 is connected with harness lever skate 4, described harness lever skate 4 connects with the steel wire rope I 5 be connected on heald frame 6 and pulls heald frame 6 times edges simultaneously, heald frame 6 is left behind, along being connected on the arc surface inside jack stick 8 by steel wire rope II 7 on heald frame 6, the outside of jack stick 8 connects some return springs 9, and return spring 9 remains tensioning state; When heald frame 6 declines, return spring 9 is stretched, stored energy; When cam 1 is turned to minor radius by large radius, spring releases energy, and makes heald frame 6 return back to top position;
Correspondingly, each jack stick 8 arc surface of described heald frame 6 both sides arranges a fixed mount 10 and load a horizontal pin 11 between two fixed mounts 10, then, a mark post 12 is penetrated in the hole at this horizontal pin 11 center, when heald frame 6 upper and lower action, can guarantee that heald frame 6 keeps upper and lower vertical motion and reduces left and right swing.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
