Ke steps on knitting machine

The present invention relates to Ke is stepped on the improvement of knitting machine.

As everyone knows, common Ke steps on knitting machine and provides a needle-bar that many grooves are arranged for each shaping head, is distributing the sinker of yarn to slide in this groove between the knitting needle; And the bar of a knocking-over sinker, it helps to distribute the end back to form row at yarn.Particularly, this sinker has a level and vertical motion, thereby allows knitting needle to pass knitted fabric and form new coil after hooking yarn and when protuberance is closed.

For the sinker of withdrawing, a so-called collection bar also is provided usually, it is driven the back and forms the compound motion comprise a vertical and horizontal component.

Ke in described type steps in the knitting machine, knock-over sinker and corresponding driving mechanism need complicated textural association, and this is not only from configuration aspects, and because sinker need carry out the assembling and the adjustment of trouble, in addition, if wearing and tearing or damage also must be changed them.

Main purpose of the present invention is to improve a kind of Ke to step on knitting machine, thereby all driving parts that save existing knock-over sinker and control its motion, so that a kind of very simple structure is provided, it can influence the purchasing price that Ke steps on knitting machine valuably, and its maintenance and adjustment.

This purpose realizes by providing a kind of Ke to step on knitting machine, this knitting machine has a crossbeam and many sinkers, wherein, there is an outstanding forward protuberance that surpasses this prominent beak end this sinker below, and form a slot with described prominent beak end, described sinker is driven and distributes yarn when travelling forward between knitting needle, form a row and drop on the described protuberance and combine with the decline of knitting needle during retraction movement, and when then travelling forward with the row of knocking in described slot.

Other features and advantages of the present invention can be from below with reference to seeing clearlyer the detailed description of accompanying drawing to preferable but not determinate embodiment, wherein:

Fig. 1 is in the knitting needle zone, comprises that improved Ke of the present invention steps on the cutaway view of the signal of knitting machine;

Fig. 2 is the side view according to a sinker of the present invention;

Fig. 3 to 10 is views of the consecutive steps that knitted fabric forms on according to knitting machine of the present invention, improved.

Referring to Fig. 1 and 2, label 1 expression Ke steps on the crossbeam of knitting machine.Crossbeam 1 has L shaped cross section, and sinker bar 2 is fixed on the top of crossbeam 1 vertical tail; After this, clear in order to describe, described sinker bar is called the sinker comb.

The upper surface of sinker comb 2 has many equidistant grooves 3, and the bearing of trend of they and this comb 2 meets at right angles.

So-called cover cap 4 is positioned on the sinker comb 2, and is rigidly connected with it; At the lower surface of described cover cap 4, promptly be provided with the parallel groove 5 of many and groove 3 on the one side of sinker comb 2.Each groove on the sinker comb 2 aligns with each groove 5 on the cover cap 4.The last lower limb of sinker 6 is guided by groove 5 and 3, and is provided with groove 7 (Fig. 2) in its front, is provided with prominent beak 8 below described groove 7, and a heel 8a is arranged in the back, and its thickness increases owing on its relative two sides two blocks of side plates 9 being installed.

So-called corrugated sheet 10 acts on heel 8a, and it is connected on the axle 11 with hinging manner, and is promoted by the kinking cam 12 that moves on track 13.Cam 12 makes sinker 6 move forward by acting on the corrugated sheet 10, thereby the yarn on the prominent beak of sinker can be hooked by groove 7, and is pushed between the knitting needle 14 that inserts the needle plate between the sinker.

For sinker is remained on forward the position, prevent in new row forming process, make the yarn action owing to knitting needle opens, thereby cause the sinker withdrawal, make corrugated sheet 10 by one be fixed on the axle 16, suitable clamp 15 blocks.Axle 16 is driven by main camshaft, thereby can forward a position to, so that clamp 15 breaks away from corrugated sheet 10, and work to collecting bar 16a, make the recess 16b engagement on itself and the sinker 6, thereby make described sinker return to its start-up point, so that the then decline of the yarn that carries out circulation.

In common knitting machine, knitting needle 14 cooperates with knocking-over sinker to form knitted fabric.According to the present invention, sinker 6 has a special shape, thereby can save knocking-over sinker and corresponding driving part fully.

According to the present invention, sinker 6 has a protuberance 17 under prominent beak 8, its outstanding forward end that surpasses prominent beak 8.

One elongated slot 18 and is limited by prominent beak lower limb and the protuberance top edge in the bottom at the top between prominent beak 8 and protuberance 17.

In these slot 18 inboards, the top edge of protuberance 17 has a tooth 19, and it will separate with groove 21 in the space 20 in its place ahead, and this groove 21 extends beyond the position of groove 7 arrival of top than groove 7 more close heel 8a from tooth 19.

The method of operation of described knitting machine is as described below.

When beginning circulation, the running position of knitting machine as shown in Figure 3, wherein, sinker 6 is in retracted position, and knitting needle 14 intersects at the place, end of prominent beak 8 with sinker.The previous knitted fabric that forms also is that knitting last row engages with knitting needle 14, and it is represented with T, and gives prominence to from slot 18.When this position, wire guide plate 22 places yarn F on the prominent beak 8.

In yarn F decline process, sinker 6 moves forward (Fig. 4), thereby yarn 7 is engaged with groove 7 on the prominent beak 8, and is pushed between the knitting needle.Meanwhile, fabric T enters slot 18, arrives groove 21 until it.

At this moment, knitting needle 14 descends; After hooking yarn F, and after being closed by the leading edge 23 that their joint of prominent beak 14a is tight against sinker comb 2 suitable roundings, described knitting needle band the coil (Fig. 5) that yarn passes the last row of knitted fabric.When knitting needle 14 continues to move down (Fig. 6), sinker 6 retreats, thereby makes yarn F break away from prominent beak 8, and drops on the protuberance 17.Therefore, arrive state shown in Figure 7, and this method enters the knocking over step, it begins the next step of sinker 6 reaches.

As shown in Figure 8, sinker 6 moves forward and makes knitted fabric enter space 20, is being supported the previous knitted fabric that form by nestling up tooth 19 (Fig. 9) by knocking over until the row that forms.This cycles through the withdrawal slightly (Figure 10) of sinker, and the rising of knitting needle 14 finishes to return to starting state shown in Figure 1.

Figure 10 also has been represented by dotted lines the path of knitting needle top process, and the shape with two 8 font decorative patterns is the same basically for it, and this is because need mobile knitting needle to make it near edge 23 between decrement phase.

Obviously, the present invention can save common knocking-over sinker axle fully, and all drive rod relevant with it, and their former being used for are carried out compound motion, and this compound motion is essential for helping the knitting needle action.Save the manufacturing expense that these parts can not only reduce knitting machine significantly, and can also utilize other part fully, thereby be convenient to assembling and adjustment.

On specific embodiment of the invention basis, also can make many improvement and variation, but all these is in same inventive concept scope.Particularly, the shape of protuberance 17 and big I be according to the requirement of knitted fabric, and collected the motion that bar and needle-bar carry out and changed by sinker.
