Please again in conjunction with shown in Figure 2, be configured on the front of needle-bar 27 with respect to woven extent, controlling a plurality of sinkers 3 with knitting setting, sinker 3 comprises press section 31, needle central portion 32, rotation section 33, the front end of sinker 3 is the press sections 31 of pushing coil, the rear end is and track 23 contacted needle central portions 32, it is on the needle-bar 27 in axle center that sinker 3 is installed in rotating shaft 26 by rotation section 33, can move up and down by the rotating shaft 26 that is contained in needle-bar 27 front end positions, making sinker 3 push the press section 31 of coil can be in the woven extent advance and retreat of knitted fabric, needle central portion 32 matches with track 23, the press section 31 of each sinker 3 changes by the displacement of needle central portion 32 on track 23 just can act on woven extent, when needle central portion 32 is mobile in track 23, press section 31 rotates to an angle with rotating shaft 26, the scope that press section 31 moves up and down is less than the notch diameter of way block 5 two ends flared channels 20, in braiding, needle central portion 32 is by flared channels 20 injections 23, and along the upper groove 6 of track 23, the track of lead-over groove 19 and the next groove 18 moves, correspondingly, press section 31 moves up and down thereupon, thereby finish the coil of braided fabric is pushed or do not pushed, the concrete course of work is as follows:

Referring again to Fig. 2, shown in Figure 3, device for controlling sinker 1 is installed in the upper end of cam control device 34, device for controlling sinker 1 and cam control device 34 are with head synchronous operation, moving of sinker 3 matches to finish knitting with rising and falling of crochet hook 28, moving of sinker 3 finished by device for controlling sinker 1, rising and falling of crochet hook 28 is that cam control device 34 by being installed on the head is finished, cam control device 34 comprises the degree order triangle 35 that is arranged at two ends, rise cam 36 between degree of the being arranged on order triangle 35, the triangle track 29 that degree order triangle 35 and rise cam 36 form, in the braiding process, by sinker 3 get on the right track 23 move and realize pushing of device for controlling sinker 1 to woven stitch, promptly when needle central portion 32 is in upper groove 6, press section 31 is in off working state, does not promptly push woven stitch, when needle central portion 32 is in the next groove 18, press section 31 is in running order, promptly pushes coil.

When head with the direction of arrow toward moving right, when promptly moving to woven extent, needle central portion 32 begins to enter into upper groove 6 from the flared channels 20 on right side, sinker 3 at this moment promptly is in the preparation state, press section 31 is the pusher wire circle not; Head continues to move right, at this moment needle central portion 32 begins to slide downwards from lead-over groove 19, corresponding rotation is made along with the motion track variation of needle central portion 32 in press section 31, along with head continues to moving, at this moment needle central portion 32 also just continues to slide downwards up to the next groove 18, after needle central portion 32 enters the next groove 18 tracks, press section 31 just begins to have entered duty, be that press section 31 begins to push coil, continuation campaign along with head, rise cam 36 just begins to promote crochet hook 28 and rises from the A point position of triangle track 29, because press section 31 has pressed coil firmly, so crochet hook 28 is in the process that rises, woven stitch can not followed crochet hook 28 and be risen together, if press section 31 coil of failing effectively to push at this moment, coil can be followed crochet hook 28 and made progress together so, so just be unfavorable for crochet hook 28 knocking overs, will produce the consequence of tuck or bad knocking over, cause knitting out bad braided fabric.

As shown in Figure 3, head continues to move with the direction of arrow, needle central portion 32 continues to slide in the next groove 18, the duty of coil is also continued keeping pushing in press section 31 so, when needle central portion 32 slides into stopper slot 24 zones at the next groove 18 middle parts, the also corresponding B point position that rises to the right-hand member of triangle track 29 of crochet hook 28, when crochet hook 28 by B point position when triangle track 29 top C point places are mobile, because the lasting rising of crochet hook 28, it is stressed also increasing to the movable block 4 in the stopper slot 24, the upwards tractive force that is subjected to crochet hook 28 when an end of movable block 4 brow-down position grooves 18 is during greater than the pressure of 2 pairs of movable blocks 4 of spring, movable block 4 will move to the opposite direction of spring 2 pressure, thereby be pressed in the stopper slot 24, at this moment, needle central portion 32 can enter in the stopper slot 24 and move along the outer rim of stopper slot 24, because the press section 31 of sinker 3 is by being pressed on the woven stitch, coil is followed and will be driven press section 31 when crochet hook 28 moves up and move up, the corresponding drive needle central portion 32 that moves up of press section 31 moves, and moving with movable block 4 of needle central portion 32 is inconsistent, therefore, if woven stitch density is too small, coil will be tightly on crochet hook 28 so; If crochet hook 28 brings the pressure of the power of coil greater than 2 pairs of movable blocks 4 of spring when rising, movable block 4 will move up, coil will be followed crochet hook 28 risings so, but this moment is because the elastic force effect of spring 2, movable block 4 is subjected to the elastic force of spring 2 stoping moving that needle central portion 32 makes progress all the time, so in this woven extent, the woven stitch tension causes coil to follow crochet hook 28 when rising, press section 31 still can be soft push coil, guaranteed weave effect.On the contrary, if this moment, the density of woven stitch was suitable, coil is easily on the crochet hook 28, the power of the crochet hook 28 rising coils that bring is less than the pressure of 2 pairs of movable blocks 4 of spring, so, movable block 4 will continue to keep original state, and the needle central portion 32 of sinker 3 can move horizontally in the next groove 18 along the edge of movable block 4, press section 31 still is in the state of pushing coil, and coil did not rise together with regard to not following crochet hook 28 when crochet hook 28 rose.

Head continues to move right with the direction of arrow, crochet hook 28 beginnings of this moment move down along the top of triangle track 29, promptly begin knocking over, when crochet hook 28 moves to the left side D point place of triangle track 29, needle central portion 32 is in the position of the next groove 18, and press section 31 is in pressed state so, if can not effectively push coil during this press section 31, crochet hook 28 will produce bad coil or tuck phenomenon when knocking over so, and the braided fabric that knits out is exactly a defective products.

Head continues to move right with the direction of arrow, when crochet hook 28 is moved to the E point place of bottom, left side of triangle track 29 by degree order triangle 35, this moment, the knocking over work of crochet hook was finished, needle central portion 32 is in the upper groove 6, press section 31 is the pusher wire circle not, state when the position of needle central portion 32 is in beginning at this moment, head shifts out woven extent by the direction of arrow, thereby finishes the braiding of one-period.When Nose Left moved, its operation principle was consistent with to the right the time, and just direction is opposite, did not just give unnecessary details at this.

When turning over needle knitting, in order to reach the requirement of turning over needle knitting, crochet hook 28 needs the higher of rising, owing to turn over the particularity of pin, no matter coil pine or tight, step on the crochet hook 28 all can be shifted coil onto certain altitude, at this moment coil will be greater than the pressure of 2 pairs of movable blocks 4 of spring with the power of crochet hook 28 risings, movable block 4 will move corresponding position with the height that coil and crochet hook 28 rise, when an end of movable block 4 moves to stopper slot 24, needle central portion 32 is just inconsistent with stopper slot 24, and movable block 4 will be no longer mobile, because the effect of spring 2, the active force that movable block 4 is subjected to spring elasticity is all the time stoping moving of needle central portion 32, so no matter where turn over needle thread loop is in, press section 31 all can flexibly effectively be pushed turning over needle thread loop, thereby has guaranteed the stability of adapter ring.

Basic functional principle when Fig. 3 shows the present invention and weaves, and in actual applications, the requirement and the effect of braiding style are more changeable, like this, simple a kind of operation method can't be met, by drive motors 16 of the present invention, by second gear 10, the 3rd gear 17 transmission sliding shoes 14, thereby adjust the position of way block 5 on cam control device 34, the track 23 and the relative position of triangle track 29 are changed, thereby realize different woven condition, specifically operation principle is as shown in Figure 4:

When head begins again to move left so that the direction of arrow is past, when promptly returning woven extent, at this moment control drive motors 16, drive the direction that sliding shoe 14 linkage guide pieces 5 move to head, the direction that is arrow is toward moving left certain position, when head moves to woven extent, way block 5 mobile working is left finished, this moment, head continued to move left so that the direction of arrow is past, described the same with Fig. 3, needle central portion 32 positions begin injection 23, and after this sinker 3 is described the same with Fig. 3 with the operation principle that crochet hook 28 cooperates, and moves out woven extent up to Nose Left; Turn left with the direction of arrow in when head and to shift out outside the woven extent by Fig. 4, just have again and begin by moving right so that the direction of arrow is past among Fig. 3, at this moment 16 while of drive motors driving guide rail piece 5 is to the direction of head, the direction that is arrow is toward moving right certain position, when head moves to woven extent, way block 5 work that moves right is finished, if head continues to move right, the control device of sinker and sinker just begin the described action of repetition Fig. 3 again with cooperating of crochet hook, therefore, in the braiding process, finished toward the moving an of direction when head, when beginning was returned toward opposite direction, drive motors 16 can require to control way block 5 according to different braidings and make corresponding mobile, change the track 23 corresponding triangle tracks 29 residing positions in the way block 5 flexibly, satisfied braiding and required and weave effect.
