Description
Technical field
The utility model relates to the auxiliary match mechanism of braiding flat-bed machine, is specifically related to braiding flat-bed machine a kind of polychrome thread-changing mechanism (being the above thread-changing structure of dichromatism or dichromatism) of (also claiming " braiding machine ").This mechanism is not only applicable to the hand-rail type braiding machine, is applicable to semi-automatic and automatic knitting machine yet.
Background technology
In braiding flat-bed machine, the effect of thread-changing structure is that the line of knitting to different colours switches in the braiding process, thereby that realizes multiple components and multiple color knits the line shuffling, thisly knits the variation that the line shuffling can produce multiple color, flower type and pattern, to enrich the effect of braided fabric.
Common thread-changing structure is a dichromatism thread-changing mechanism in the existing straight-bar machines, promptly can adopt two kinds of colors to knit line under not shutdown situation, knits line by replacing and realizes shuffling.This dichromatism thread-changing mechanism is by two spindle with wire, shuttle adjuster (also claiming " pagoda ") and clash into driving lever three parts and form.Spindle with wire is connected and composed by shuttle head (shuttle mouth), shuttle bar (shuttle body) and shuttle box (shuttle pin), and two spindle with wire are slidingly mounted on the shuttle rail by shuttle box; Shuttle adjuster is installed in head, and shuttle adjuster mainly is made up of bearing, thumb wheel, switching camshaft and two telescopic tongues; The bump driving lever is made up of holder and driving lever, and holder is fixed on an end of shuttle rail.During work, when horizontal mobile head is to an end position by hand, thumb wheel on the shuttle adjuster and the driving lever bump that is located on shuttle rail one end, thumb wheel is turned an angle, drive the switching camshaft and do corresponding rotation, thereby switch the telescopic location of two telescopic tongues, select corresponding spindle with wire to enter duty, realize knitting line and change with this.
The shortcoming of existing dichromatism thread-changing mechanism is: 1, parts are many, and complex structure makes trouble, and breaks down easily in the use; When 2, particularly running into double knit and elastic force braided fabric, same spindle with wire head will be changed two and knit line or three when knitting line, and is time-consuming, and breaks down easily, has joint (dotted line) to exist on the woven article, need be by manually handling; 3, except thread-changing function difference and, and be difficult for automatic thread-changing; 4, this mechanism generally can only switch knitting between the line of two kinds of colors; if realize the thread-changing that color is knitted line more than three kinds or three kinds; then essential the shutdown; by manual operations; pull down dichromatism and knit one of line, replace to the third color, carry out knit operation again; not only operating efficiency is extremely low, and bothers very much.
Summary of the invention
The utility model provides a kind of straight-bar machines dichromatism or the above polychrome of dichromatism to knit the line thread changing device, its objective is to realizing the polychrome thread-changing function of straight-bar machines, improves the thread-changing quantity and the efficient of cross machine knitting, further to enrich the effect of braided fabric.
For achieving the above object, the technical solution adopted in the utility model is: a kind of straight-bar machines polychrome thread-changing mechanism, comprise spindle with wire and shuttle adjuster, and spindle with wire is connected and composed by shuttle head, shuttle bar and shuttle box, and shuttle box is slidingly mounted on the shuttle rail, and shuttle box is provided with latch notch with wire; The quantity of spindle with wire is at least two, staggers mutually in the locus that each spindle with wire moves on the shuttle rail; Shuttle adjuster mainly is made up of the shuttle mechanism that selects of pedestal, accent shuttle plate and corresponding spindle with wire quantity, pedestal is fixed on the flat-knitting machine head, vertically be set side by side with row's installing hole on the pedestal, be equipped with a vertical long slot bore on the sidewall of each installing hole, the outer face of long slot bore is the inclined-plane, and the inclined-plane is provided with one and transfers the shuttle plate, and this transfers the shuttle plate across platoon leader's slotted eye, its root and pedestal are hinged, anterior by the flexible member gland on the long slot bore of posterior segment; Settle a cover to select shuttle mechanism in each installing hole, every cover selects shuttle mechanism to comprise telescopic tongue, return spring and alignment pin, telescopic tongue places installing hole, and the latch notch with wire of a spatially corresponding shuttle box, alignment pin is vertically fixed on the telescopic tongue, and be arranged in long slot bore, it is enough to jack-up when moving forward with telescopic tongue by effect end of transferring shuttle plate one side and transfers the shuttle plate, return spring act on the relative installing hole of telescopic tongue after contract on the direction.
Related content in the technique scheme is explained as follows:
1, in the such scheme, snaps in latch notch with wire on the shuttle box smoothly, and drive whole spindle with wire and on the shuttle rail, move, can be provided with sliding sleeve, on glide direction, be provided with spring between sliding sleeve and the telescopic tongue head at the head of telescopic tongue in order to make telescopic tongue.
2, in the such scheme, switch spindle with wire for convenience, the one stroke driving element can be set in the rear end of each telescopic tongue, the trip driving element is an electromagnetic valve, or motor-driven mechanism, or manual-operating mechanism.Electromagnetism palace gate and motor-driven mechanism are used for automatically or semiautomatic control, and manual-operating mechanism is used for manual operation.
3, in the such scheme, when straight-bar machines is the unit header structure, a shuttle adjuster is set on the unit head, spindle with wire is in straight-bar machines one end setting, and shuttle adjuster matches with the spindle with wire of an end.
4, in the such scheme, when straight-bar machines is the two-shipper header structure, two kinds of designs are arranged:
(1), a shuttle adjuster is set on each unit head, spindle with wire is provided with at the straight-bar machines two ends, two shuttle adjusters match with the set spindle with wire of corresponding end respectively, and change by the rise cam controlling organization.
(2), two shared shuttle adjusters of unit head, spindle with wire is provided with at the straight-bar machines two ends, shuttle adjuster matches with the set spindle with wire in two ends respectively, and changes by the rise cam controlling organization.A described shared shuttle adjuster preferred version is arranged on the symmetrical centre line position of two-shipper head.
5, in the such scheme, described flexible member refers to members such as torsion spring, stage clip, extension spring or elastic pressuring plate.When adopting torsion spring, on the end axle of transferring shuttle plate two ends, will transfer shuttle plate gland on long slot bore torsion spring set; When adopting stage clip or elastic pressuring plate, directly be pressed in and transfer on the shuttle plate; When adopting extension spring, directly be pulled in and transfer on the shuttle plate.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
