Description

The movable latch needles piece of detachable

The utility model relates to a kind of latch needles piece, and the movable latch needles piece of particularly a kind of detachable is installed on the needle-bar of warp knitting cloth machine, is used for braiding.

Employed pin piece on the existing warp knitting cloth eedle bed generally is to be made of base and one group of latch needles, adopts the casting of tin pewter one to form between the two.There is following point in this tin casting pin piece: at first, because latch needles is a tin casting pin, so intensity is relatively poor, yielding, can influence the flatness on woven cloths surface after the distortion; Secondly, the situation that broken needle in the braiding process, usually can occur, behind the broken needle since the latch needles of pin piece and base for fixedlying connected, so must unload whole latch needles piece, stay one and of a size point of whole latch needles piece can for like this surface of woven cloths, thereby influence the quality of woven cloths; Once more, when the broken needle piece is repaired, at first must at high temperature melt detin, can take out the latch needles that does not have damage, cast with base again, and its hardness is affected behind the at high temperature molten tin of latch needles, the ABRASION RESISTANCE of latch needles is descended significantly, shortened the service life of latch needles piece; At last, existing tin casting pin piece adopts external import mostly, has the cost height, repairs defectives such as bad pin and the inconvenience of replacing pin piece.

The purpose of this utility model be to provide a kind of compact conformation rationally, be convenient to install, latch needles intensity height, not yielding and behind broken needle latch needles can change separately and need not unload latch needles piece, the movable latch needles piece of detachable easy and simple to handle, that cost is low.

The purpose of this utility model is achieved like this, the movable latch needles piece of a kind of detachable, be by base 9, one group of latch needles 3 is formed, offer caulking groove 7 on the described base 9, one trick plate 8 is installed in the caulking groove 7 by the boss on it, trick plate 8 is provided with row's screen 5 and row's needle tray 6, both are distributed in distance, one end of one group of latch needles 3 is embedded in respectively in the needle tray 6 between two screens 5 accordingly, one pressing plate 1 is installed in the top of base 9, pressing plate 1 is provided with stitch groove 11 and pressing plate tongue 2, the stitch 4 of one group of latch needles 3 is embedded in the stitch groove 11, tiltedly cooperating along 17 of pressing plate tongue 2 and one group of latch needles 3, a bolt 15 passes on screw 14 on the pressing plate 1 and the base 9 behind the corresponding screw pressing plate 1, one group of latch needles 3 and base 9 threes fix.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is a structure diagram of the present utility model.

The utility model is provided with positioning convex strip 12 in the centre of pressing plate 1, offers locating slot 10 in the corresponding position of base 9, by the cooperate top that pressing plate 1 be installed in base 9 of positioning convex strip 12 with locating slot 10.

Base 9 of the present utility model, trick plate 8, latch needles 3, pressing plate 1 adopt all that stainless steel material is molded to form, and have certain ABRASION RESISTANCE and impact resistance.Base 9 is

Shape,

Offer caulking groove 7 on the lower plane of shape base 9,

Offer the boss of locating slot 10, one trick plates 8 by its bottom on the last plane of shape base 9 and be installed in the caulking groove 7, closely and not loosening for trick plate 8 and caulking groove 7 are cooperated between the two, caulking groove 7 generally can be designed to swallow tail shaped slot, or dovetail groove.The utility model offers row's screen 5 and row's needle tray 6 in the upper end of trick plate 8, be distributed in distance between screen 5 and the needle tray 6, and a needle tray 6 promptly is set between two screens 5, and needle tray 6 is used to install an end of latch needles 3.Latch needles 3 of the present utility model is made up of pinhock 21, needle body, stitch 4, on needle body, be provided with one tiltedly along 17, when an end of latch needles 3 inserts in the corresponding needle tray 6, the last plane 20 of latch needles 3 one ends just is positioned on the same horizontal plane with a upper end of arranging screen 5, and stitch 4 then is positioned at the top of screen 5 upper ends.The utility model is provided with pressing plate tongue 2 at the leading section of pressing plate 1, the centre is provided with positioning convex strip 12, pressing plate tongue 2 tool inclined-planes 18, platform 19, offer a stitch groove 11 at the rear of platform 19, the effect on inclined-plane 18 is and tiltedly the cooperating along 17 of one group of latch needles 3, the effect of platform 19 is that the last plane 20 of one group of latch needles 3 one end is pushed down, the effect of stitch groove 11 is that the stitch 4 of one group of latch needles 3 is fixing, positioning convex strip 12 is embedded in the locating slot 10 of base 9, make pressing plate 1 and base 9 location, and pass on screw 14 on the pressing plate 1 and the base 9 by a bolt 15 and behind the corresponding screw both to be fixed.The utility model also offers a pair of

fixing hole

13,16 respectively on pressing plate 1 and base 9, be installing hole, is convenient to the latch needles piece is installed on the needle-bar of warp knitting cloth machine.

The utility model is assembled like this, at first the boss of trick plate 8 by its bottom is installed in the caulking groove 7 of base 9, both are tight fit, end with the band stitch 4 of one group of latch needles 3 is plugged on respectively in the corresponding needle tray 6 of trick plate 8 again, both also are tight fit, and make the last plane 20 of one group of latch needles 3 one end equal with the upper end of row's screen 5, and the stitch 4 of one group of latch needles 3 is positioned at the top, upper end of row's screen 5, then with pressing plate 1 by the positioning convex strip on it 12 with the cooperating of locating slot 10 of base 9 both are located, at this moment make the inclined-plane 18 of the pressing plate tongue 2 on the pressing plate 1 be pressed in one group of latch needles 3 tiltedly along on 17, the platform 19 of pressing plate tongue 2 is pressed on the last plane 20 of one group of latch needles 3, the stitch 4 of one group of latch needles 3 is positioned at stitch groove 11, one bolt 15 passes on screw 14 on the pressing plate 1 and the base 9 behind the corresponding screw that both fix with pressing plate 1 and base 9, and one group of latch needles 3 is fixed between the two gets final product.
