Description
Technical field
The utility model relates to a kind of knitting mechanism of double rib warp loom, particularly relates to the latch needles bed assembly in the double rib warp loom knitting mechanism.
Background technology
Latch needles bed assembly in the existing double rib warp loom knitting mechanism, adopt following two kinds of structures usually: a kind of is pin piece formula, promptly is made up of a needle-bar base and a fairly large number of pin piece; The width of each pin piece is generally 25.4 millimeters; Be fixed with some latch needles through adhesives on each pin piece, each pin piece is installed on the needle-bar base through bolt, the latch needles bed assembly of this structure; When needing to change when single latch needles appearance damage; Then must whole pin piece together be changed, so not only cause waste serious, and increased production cost; Another kind is an integral type, and the latch needles bed assembly of this structure comprises needle-bar base I, trick plate II, latch needles, pin pressing plate and pressed sheet; Offer the needle tray II a that matches with said latch needles on the said trick plate II along its length; Said pressed sheet is pressed on said latch needles in the needle tray II a of said trick plate II through the pin pressing plate; Said trick plate II and needle-bar base I are one, and promptly shown in figure 15 is a single piece; Add man-hour, be generally in integrally formed by said trick plate II and needle-bar base I, length and inlay latch needles after milling needle tray on 3～4 meters the whole needle-bar, latch needles is fixed through pressed sheet, pin pressing plate then.Though have the advantage of the single replacing of latch needles ability, also there is following defective in the latch needles bed assembly of this structure; Promptly because on whole integrally formed needle-bar of trick plate II and needle-bar base I during the processing needle tray, must guarantee uniformity, the symmetry of needle tray of the forward and backward needle-bar of double rib warp loom, so the requirement on machining accuracy of every needle-bar is high; Difficulty of processing is very big, and percent defective is high, simultaneously; Since the necessary complete use of forward and backward needle-bar, therefore, when damaging appears in certain root of forward and backward needle-bar; Then must together change by forward and backward two needle-bars, cause wasting huge, increased production cost greatly; And the latch needles bed assembly of this structure also exists the accumulated error that causes owing to reasons such as processing, makes the big more defective of the big more needle tray deviation of a width of cloth, and in addition, the spacing of latch needles also can't be regulated.
Summary of the invention
The technical problem that the utility model will solve provides a kind of not only latch needles can single replacing, and can eliminate the accumulated error that produces when processing needle tray, and the latch needles spacing can regulate, the latch needles bed assembly of easily manufactured, double rib warp loom that production cost is lower.
For solving the problems of the technologies described above, the utility model adopts a kind of like this latch needles bed assembly of double rib warp loom, comprises needle-bar base, trick plate, latch needles, pin pressing plate and pressed sheet; Offer the needle tray that some match with said latch needles on the said trick plate along its length; Said pressed sheet is pressed on said latch needles in the needle tray of said trick plate through said pin pressing plate; Said trick plate and needle-bar base are splits; And this trick plate is combined by a plurality of independently segment trick plates; Said each segment trick plate is fixedly connected with said needle-bar base respectively, and this latch needles bed assembly comprises that also one is used to regulate the latch needles spacing of adjacent segment trick plate joint and the location adjusting device that adjacent segment trick plate is located each other.
A kind of preferred implementation as the utility model; Described location adjusting device is by the needle tray inserted sheet that is arranged between the needle tray of said adjacent segment trick plate joint; And the rectangle that is separately positioned on said adjacent segment trick plate joint rectangular recess protruding and that match with this rectangle convexity constitutes; Said rectangle convexity is provided with the groove that supplies said needle tray inserted sheet to intert, and the groove width of this groove is greater than the thickness of said needle tray inserted sheet.
The length of described each the segment trick plate of the utility model is preferably 50～350 millimeters.
After adopting said structure; Because the latch needles of the utility model is pressed in the needle tray of said trick plate through pressed sheet, pin pressing plate; Thereby occur damaging and when needing to change when single latch needles; Only need that the latch needles that damages is taken out replacing separately and get final product, thereby avoided the wasting phenomenon that needs whole pin piece together to change in the prior art.Because trick plate and needle-bar base are splits; And trick plate is combined by a plurality of independently segment trick plates; The length of described each the segment trick plate of the utility model is preferably 50～350 millimeters; Thereby the utility model this by a plurality of length be the trick plate formed of 50～350 millimeters segment trick plates with prior art in length be that 3～4 meters single piece trick plate is compared; Difficulty of processing and production cost reduce greatly, and the trick plate of this segmental structure is easily manufactured, can effectively eliminate the accumulated error that produces when processing needle tray, thereby have improved the braiding precision greatly.Because the utility model also is provided with one and is used to regulate the latch needles spacing of adjacent segment trick plate joint and the location adjusting device that adjacent segment trick plate is located each other; This location adjusting device is preferably by the needle tray inserted sheet and be separately positioned on the protruding and rectangular recess of the rectangle of adjacent segment trick plate joint and constitute; Thereby can be through between the needle tray of adjacent segment trick plate joint, inserting the needle tray inserted sheet; Regulate the distance between the latch needles in the needle tray of adjacent segment trick plate joint, thereby guarantee that the latch needles spacing reaches the required precision of regulation; Through the rectangle convexity of said adjacent segment trick plate joint and cooperatively interacting of rectangular recess, adjacent segment trick plate is located each other, thereby both are held in the correct position.
In the utility model, between said pin pressing plate and said latch needles, also be provided with the banded pad of processing by flexible material, this pad is combined by a plurality of independently segment pads.The triangular groove that is respectively equipped with triangular hill and matches in the joint of said adjacent segment pad with this triangular hill.After adopting said structure, on the one hand, can avoid latch needles in installing and working, to sustain damage, thereby prolong the service life of latch needles, on the other hand, can latch needles be pressed in the needle tray of trick plate more reliably.
In the utility model, said pin pressing plate combines the triangular groove that is respectively equipped with triangular hill and matches with this triangular hill in the joint of said adjacent segment pin pressing plate by a plurality of independently segment pin pressing plates.After adopting said structure, on the one hand, the pin pressing plate of this segmental structure is easily manufactured, thereby can reduce production costs, and on the other hand, can latch needles be pressed in the needle tray of trick plate more reliably.
