Abstract
The utility model relates to a kind of grooved needle for warp knitting machine, and this groove pin ensures to grip stable, accurate positioning.Comprise: pinhock, needle tray, shank, groove and small boss.Be primarily characterized in that the front place of the pin of shank is provided with compressed grooves, compress gland and match with it tongue, just compress groove pin after gland force, can position up and down groove pin simultaneously; Be provided with two place's small boss at needle back place, this two places small boss is located on grooved needle bed inclined-plane for groove pin, and 2 become line, accurate positioning.The length of described shank shortens, and the grooved needle bed height matched with it shortens, and alleviates the weight of grooved needle bed.A kind of grooved needle for warp knitting machine of the present utility model, easy, the accurate positioning of grooved needle bed processing that having matches uses, gripping are reliable and stable, are conducive to improving the degree of accuracy of lopping action and improve the running speed of warp knitting machine.
Description
Technical field
The present invention relates to the auxiliary equipment of warp knitting machine, especially a kind of grooved needle for warp knitting machine.
Background technology
Grooved needle for warp knitting machine forms primarily of pinhock, syringe needle, needle tray, shank and stitch.And the structure of open stem, directly have influence on the structure of grooved needle bed and the installation of groove pin and location.Existing grooved needle for warp knitting machine, its shank part is generally linear pattern, this straight type shank, it is only provided with a location division at stitch place, and stitch and location division are connected by a transition arc, when warp knitting machine high-speed motion, the groove pin of this structure is unfavorable for positioning on the inclined-plane of grooved needle bed, thus affects gripping stability and the reliability of groove pin.Another existing yarn is comparatively thick, and the pulling force produced when moving up and down when groove pin is comparatively large, and pinhock is when by high-frequency line pulling force, and needle body easily causes displacement or distortion, thus is unfavorable for lopping campaign.
Summary of the invention
For the defect that prior art exists, the object of this invention is to provide the accurate positioning of a kind of energy, ensure that groove pin grips the grooved needle for warp knitting machine of stability.
The present invention solves the technical scheme that its technical problem takes: a kind of grooved needle for warp knitting machine, comprising: pinhock, needle tray, shank, groove and small boss.Be primarily characterized in that: the front place of pin of shank is provided with compressed grooves, compress gland and compressed grooves and match tongue, be provided with two place's small boss at the needle back place of shank, this two places small boss is located on grooved needle bed inclined-plane for groove pin.
Compared with prior art, instant invention overcomes the defect of prior art, the groove at place and two place's small boss at needle back place before shank pin, ensure that the stability that groove pin grips and reliability, make the location of groove pin more accurate, needle body is not easy to cause displacement or distortion, and it is good to process the performance that easy, anti-high frequency pulls, thus realizes gripping the object stable, lopping quality is high.

Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with accompanying drawing, the present invention is described in further detail.
With reference to accompanying drawing: a kind of grooved needle for warp knitting machine of the present invention, comprising: pinhock (1), needle tray (2), shank (3), groove (4) and small boss (5).Be primarily characterized in that: the front place of pin of described shank (3) is provided with compressed grooves (4), be provided with two place's small boss (5) at needle back place.
Described a kind of grooved needle for warp knitting machine, when installing groove pin, the compressed grooves (4) at place is exerted a force by gland (6) and compresses before described shank (3) pin, compresses gland (6) and matches with it tongue, makes compressed grooves (4) and compresses gland (6) and closely engage; Have gap in the engagement place of groove (4) and gland (6), gland (6) extrudes more inside, and their engagement place is tighter, and described gland (6) to be locked with grooved needle bed (7) by bolt (8) and is connected.Described shank (3) needle back place is arranged in the guide groove of grooved needle bed (7), and two place's small boss (5) that needle back place is provided with are located on grooved needle bed (7) inclined-plane for groove pin, and 2 become line, accurate positioning.
Described a kind of grooved needle for warp knitting machine, the groove pin of this structure can shorten the length of shank (3), and the grooved needle bed (7) matched with it just can shorten, and so just alleviates the weight of grooved needle bed (7).
In the above-described embodiments, shank (3) part, owing to being provided with groove (4) and small boss (5), makes groove pin in use locate more stable, and when pinhock (1) is when by high-frequency line pulling force, needle body is not yielding.Adopt the groove pin of the location of structure thus completely, accurate positioning, all groove pin good positioning consistency, machine because of groove pin accurate positioning reliable, the position of other loop-forming elements relative groove pin adjustment also more accurately and stable, thus is beneficial to the lopping campaign of machine.
Above-described embodiment just preferred embodiment done for a better understanding of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and are all covering scope of the present invention.
Claims (1)
1. a grooved needle for warp knitting machine, comprise pinhock (1), needle tray (2), shank (3), groove (4) and small boss (5), be primarily characterized in that the front place of pin of shank (3) is provided with compressed grooves (4), compress gland (6) and match tongue with compressed grooves (4), be provided with two place's small boss (5) at the needle back place of shank (3), this two place small boss (5) locates on grooved needle bed (7) inclined-plane for groove pin.
