A kind of jacquard yarn guiding device
Technical field:
The present invention relates to textile machine, is specifically a kind of jacquard yarn guiding device.
Background technology:
Existing jacquard is when weaving jacquard fabric, often need the yarn of hundreds and thousands of pin, if after in braiding process, wherein the yarn of a certain pin breaks, need the yarn for subsequent use on most limit to win in feeding jacquard fabric to substitute the yarn broken, at this moment, the yarn as resolutely fallen is in centre position, is introduced through the yarn come will be formed in a very large angle feeding jacquard fabric from limit, and this can affect the braiding quality of jacquard fabric, this yarn also can be made in addition easily to break.
In prior art, Jacquard textile machine yarn guiding device is arranged on yarn guiding wheel on oscillating bearing, and oscillating bearing is fixed on slide block, and slide block is arranged on slide plate.There is following problem in described guider: yarn is still led by yarn guiding wheel, but due to the coaxial rotation of yarn guiding wheel, namely yarn can only advance along the yarn groove of yarn guiding wheel outer shroud, even if be arranged on oscillating bearing, also can only play the effect of guide, the problem of yarn wide-angle yarn feeding cannot be solved
For above-mentioned technical problem, be necessary to take new technical scheme to solve.
Summary of the invention:
The object of the invention is for prior art not enough, a kind of jacquard yarn guiding device that can solve the technical problems such as the yarn broken yarn of any wide-angle is provided.
For achieving the above object, the invention provides a kind of jacquard yarn guiding device, it comprises transverse slat, front guide holder and rear guide holder; Described transverse slat is fixed by the installing hole on two side connecting plates and jacquard frame; Described transverse slat offers chute; Described front guide holder and rear guide holder are plugged in chute; Described front guide holder comprises horizontal guide bracket, longitudinal guide bracket and oscillating bearing; Described longitudinal guide bracket is plugged on described horizontal guide bracket by guide rail; Described oscillating bearing is hinged on described longitudinal guide bracket; Described rear guide holder comprises base and yarn guiding rod; Described yarn guiding rod is screwed onto on described base; Described oscillating bearing offers yarn passing hole; Described yarn guiding rod offers thread guide eyelet.
Preferred as technique scheme, described oscillating bearing is made up of lower spherical and top square column, and described yarn passing hole is opened on the square column of top, described yarn passing hole two ends rounding.
Preferred as technique scheme, described yarn guiding rod upper end is spheroid; Described thread guide eyelet is opened in yarn guiding rod inside; Described thread guide eyelet upper port is arranged on spheroid side and rounding; Described thread guide eyelet lower port is arranged on described yarn guiding rod bottom center.
Preferred as technique scheme, described the highest of longitudinal guide bracket is higher than two side connecting plates.
Preferred as technique scheme, described yarn guiding rod most significant end is lower than described the highest of longitudinal guide bracket.
Beneficial effect of the present invention is: by the cooperation of described front guide holder and rear feeder seat, can adapt to the yarn of any wide-angle, reduces yarn broken yarn.

Detailed description of the invention:
Below in conjunction with accompanying drawing, following describing in detail is done to the present invention.For sake of convenience, following " on ", D score, "left", "right" be consistent with the direction, upper and lower, left and right of accompanying drawing itself.
As shown in Figure 1 to 4, a kind of jacquard yarn guiding device, it comprises transverse slat 10, front guide holder 234 and rear guide holder 56; Described transverse slat 10 is fixed with jacquard frame by the installing hole 12 on two side connecting plates 11; Described transverse slat 10 offers chute 13; Described front guide holder 234 and rear guide holder 56 are plugged in chute 13; Described front guide holder 234 comprises horizontal guide bracket 20, longitudinal guide bracket 30 and oscillating bearing 40; Described longitudinal guide bracket 30 is plugged on described horizontal guide bracket 20 by guide rail; Described oscillating bearing 40 is hinged on described longitudinal guide bracket 30; Described rear guide holder 56 comprises base 50 and yarn guiding rod 60; Described yarn guiding rod 60 is screwed onto on described base 50; Described oscillating bearing 40 offers yarn passing hole 41; Described yarn guiding rod 60 offers thread guide eyelet 61.
Described oscillating bearing 40 is made up of lower spherical 401 and top square column 402, and described yarn passing hole 41 is opened on top square column 402, described yarn passing hole 41 two ends rounding.
Described yarn guiding rod 60 upper end is spheroid; It is inner that described thread guide eyelet 61 is opened in yarn guiding rod 60; Described thread guide eyelet 61 upper port is arranged on spheroid side and rounding; Described thread guide eyelet 61 lower port is arranged on described yarn guiding rod 60 bottom center.
Described longitudinal guide bracket 30 the highest is higher than two side connecting plates 11.
Described yarn guiding rod 60 most significant end is lower than described longitudinal guide bracket 30 the highest.
During specific works, according to the path that yarn is come, the position of guide holder 234 on transverse slat 10 before adjustment, then the position of longitudinal guide bracket 30 on front guide holder 234 is adjusted, then the direction that oscillating bearing 40 makes yarn passing hole 41 aim at yarn to come as far as possible is adjusted, the length that after last adjustment again, the position of guide holder 56 on transverse slat 10 and yarn guiding rod 60 stretch out, the lower port of thread guide eyelet 61 is made to aim at feed, make the lower port of thread guide eyelet 61 towards the direction of yarn passing hole 41, such yarn just can enter feed through yarn passing hole 41 and thread guide eyelet 61 accurately, reduce yarn broken yarn.
