In order to alleviate harness eye to the wearing and tearing of warp thread, China Patent Publication No. CN200940182, open day on 08 29th, 2007, the name of innovation and creation is called a kind of improved wire heald, and this application case discloses a kind of improved wire heald, and the characteristics of this heald are to apply smooth High Strength Wear-Resistance Material at the harness eye periphery, as enamel layer, alloy layer, polytetrafluoroethylene (PTFE), poly-perfluor layer, or the stage casing that heald rod is offered harness eye is made by smooth High Strength Wear-Resistance Material.Adopt this technical scheme, harness eye reduces the coefficient of friction of warp thread, can reduce the frictionally damage of warp thread in to a certain degree, however the High Strength Wear-Resistance Material that applies easily be worn away, thereby cause reducing warp thread wearing and tearing disabler.China Patent Publication No. CN202595399U, open day on December 12nd, 2012, the name of innovation and creation is called a kind of novel heald, this application case discloses a kind of novel heald, and the characteristics of this heald are to be provided with the dead axle cylinder on heald rod, and the dead axle cylinder is positioned at the center of harness eye, the dead axle cylinder is perpendicular to the heald rod of heald, the dead axle cylinder is made of support and resilient sleeve, and resilient sleeve in axial direction has groove, being sleeved on support of resilient sleeve activity.Adopt this technical scheme, when warp thread passes harness eye before the dead axle cylinder is drawn towards machine after one week, in the heald course of work, the dead axle cylinder rotates under the warp tension effect, the rubbing action of harness eye and warp thread changes rolling friction into by traditional sliding friction, coefficient of friction reduces greatly, and the fretting wear of warp thread is greatly relaxed, yet the dead axle cylinder may block the broken yarn line, the mode of gaiting differs from traditional heald, and operation is comparatively complicated.
Summary of the invention
For the problem of above-mentioned existence, the object of the present invention is to provide a kind of heald that reduces rubbing action between harness eye and warp thread, and the mode of gaiting of applicable traditional heald.
To achieve these goals, technical solution of the present invention adopts the heald to existing textile machinery to carry out Innovative method, namely the structure that is arranged on the harness eye on heald rod is improved, the thickness at described harness eye place is the twice of heald rod thickness, is provided with in harness eye to be parallel to each other and movable upper rotating shaft, the lower rotary shaft of installing.Upper rotating shaft, lower rotary shaft are perpendicular to heald rod.
Owing to having adopted above technical scheme, the present invention has changed the harness eye structure of traditional heald, rotating shaft on being provided with in harness eye, lower rotary shaft, before being drawn towards machine after the warp thread of bringing from the loom rear passes between upper rotating shaft and lower rotary shaft, this is just when keeping traditional mode of gaiting, the rubbing action that has realized heald and warp thread changes rolling friction into by traditional sliding friction, thus the problems such as mode of operation complexity of having avoided the improvement of heald structure to bring.This has just not only reduced the coefficient of friction between warp thread and harness eye greatly, the fretting wear of warp thread is greatly relaxed, reduce the fabric quality problems such as width barrier of resolving through stopping and causing, reduced simultaneously the quality requirement to warp thread, increased the weavability of warp thread.Simultaneously, the mode of gaiting of novel heald of the present invention and traditional heald are identical, easy to operate.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in drawings, a kind of novel heald, it is by heald rod 1 and be opened in harness eye 2, upper rotating shaft 3, the lower rotary shaft 4 on heald rod 1 and be opened on the P type at heald rod 1 two ends that under heald end loop and P type, heald end loop consists of.The thickness at described harness eye 2 places is the twice of heald rod 1 thickness, symmetrically on harness eye 2 two sides offer two pairs of through holes, upper rotating shaft 3 and lower rotary shaft 4 all are cylindric, upper rotating shaft 3 and lower rotary shaft 4 are parallel to each other and two ends are inserted in respectively in the through hole of harness eye 2 two sides actively, rotate flexibly to guarantee upper rotating shaft 3 and lower rotary shaft 4.Upper rotating shaft 3, lower rotary shaft 4 are perpendicular to heald rod 1.The thickness at harness eye 2 places is the twice of heald rod 1 thickness, so that the installation of upper rotating shaft 3 and lower rotary shaft 4.Between upper rotating shaft 3 and lower rotary shaft 4 at a distance of 1-3mm, warp thread passes between upper rotating shaft 3 and lower rotary shaft 4, this just make the mode of gaiting of novel heald of the present invention and traditional heald identical, semi-automatic and the mode of automatically gaiting that applicable textile mills generally adopt, the problems such as mode of operation transformation of effectively having avoided the improvement of heald structure to bring.Simultaneously, warp thread is difficult for by card disconnected, reduces the effect stability of warp thread wearing and tearing.
During heald work, before being drawn towards machine after the warp thread of bringing from the loom rear passes between upper rotating shaft 3 and lower rotary shaft 4, warp thread is done harness motion with heald and is moved up and down between upper rotating shaft 3 and lower rotary shaft 4, simultaneously at wefting insertion, beat up, batch under the cooperation with let-off motion to machine the place ahead to movement.because warp thread has certain tension force, when warp thread comes in contact with upper rotating shaft 3 or lower rotary shaft 4 in harness eye 2, produce frictional force between meeting and upper rotating shaft 3 or lower rotary shaft 4, upper rotating shaft 3 or lower rotary shaft 4 rotate under this frictional force effect, this has just changed the interaction mode between harness eye 2 and warp thread in traditional heald, make in traditional heald between harness eye 2 and warp thread the sliding friction of cutting shape by upper rotating shaft 3, rolling friction between lower rotary shaft 4 and warp thread substitutes, coefficient of friction is reduced to original 1/40-1/60, frictional force reduces greatly, the fretting wear that warp thread bears obviously reduces.
