Description
Technical field
The present invention relates to a kind of knitting mechanism of warp knitting machine, particularly relate to the colored card wire in the warp knitting machine knitting mechanism.
Background technology
Colored card wire in the existing warp knitting machine knitting mechanism adopts following two kinds of structures usually, the shank of first kind of structure and syringe needle are splits, the syringe needle lower end is provided with thread guide eyelet, the upper end is plugged in the endoporus of shank end, at the splicing position of syringe needle and shank injection adhesive both is fixed together; The colored card wire of this structure, when weaving, owing to pass the yarn of syringe needle thread guide eyelet syringe needle is applied downward pulling force, therefore under situations such as adhesive takes place to wear out, the phenomenon that syringe needle comes off from shank often takes place, and this come off before start or in weaving all difficulty be found, thereby often cause fabric inferior.The shank of second kind of structure and syringe needle be made into integration or by welding both are fixed together at the splicing position of syringe needle and shank, though the phenomenon that syringe needle comes off from shank can not take place in the colored card wire of this structure, but because shank and syringe needle processing difficulties when being a single piece, percent defective and production cost are higher, and, when syringe needle wearing and tearing occur or interrupts in the machine debug process in the braiding process, this one or welded shank and syringe needle must together be scrapped and change, and have therefore more increased the production cost of enterprise.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of syringe needle that not only makes and is difficult for coming off from shank, and when syringe needle weares and teares or interrupts, only needs it is extracted replacing and warp knitting machine pattern card wire accurately and reliably is installed.
For solving the problems of the technologies described above, a kind of warp knitting machine pattern card wire of the present invention, comprise shank and syringe needle, the lower end of described syringe needle is provided with thread guide eyelet, and this flower card wire comprises that also can be located described syringe needle, be installed in with compressing the positioning compression device on the described shank.
As a kind of preferred implementation of the present invention, described positioning compression device comprises and is arranged on the groove that L-shaped being used to of described shank sidepiece and cross section plugs described syringe needle, be fixedly mounted on the described shank and be positioned at the cover plate on described groove top, be fixedly mounted on the described cover plate and be positioned at least one flexible positioning piece of described groove, and be arranged on the detent on the described syringe needle; Described flexible positioning piece is that circular arc positioning convex and the L shaped elastic arm that extends along this positioning convex both sides constitute by the centre; The size of the detent on the described syringe needle and shape and described positioning convex are suitable.
After adopting such structure, because colored card wire of the present invention also is provided with a positioning compression device that syringe needle can be located, compressed be installed on the shank, by this positioning compression device, the present invention preferably combines cooperation by the detent on the syringe needle with the positioning convex of fixing flexible positioning piece on the cover board, and by syringe needle accurately being located, is pressed on reliably on the shank along the L shaped elastic arm of positioning convex both sides extension, thereby not only make syringe needle in weaving process, be difficult for coming off from shank, and it is simple in structure, process easy, with low cost; Because syringe needle and shank are the branch body structure,, only need it is extracted replacing from the L shaped groove of shank sidepiece, thereby greatly reduce production cost again when syringe needle weares and teares or interrupts.
As a kind of improvement of the present invention, described positioning compression device also comprises two arc-shaped elastic sheets that are fixedly mounted on the described cover plate and are positioned at described groove, described flexible positioning piece is one, and described two arc-shaped elastic sheets are arranged on the both sides up and down of described flexible positioning piece symmetrically.Adopt such structure, syringe needle is pressed on the shank more reliably, thereby work is more reliable, and processing is also more convenient.
As another kind of improvement of the present invention, the width W of described groove
1Width W with described syringe needle
2Equate that the upper end of described syringe needle also is provided with chamfering.Adopt such structure, on the one hand syringe needle is installed on the shank more accurately, can make the replacing of syringe needle more convenient on the other hand.
