One is located at second follower lever 45 of second driving lever, 44 1 sides, and its top is to have one second relative connecting portion 451, and the bottom then has one second extension rod 452, and its second relative connecting portion 451 is to be connected with second connecting portion 443 of second driving lever 44; After being exposed at clip slot 23 outside second actuation part 441 of second driving lever 44, another actuating cam 53 of correspondence can drive second actuation part 441 and move down, and interlock second extension rod 452 moves down on its disk 5.
The one interlock group 46 of being abutted against mutually with second follower lever 45, it is that two ends at a mobile jib 461 are connected with one first respectively and drive bar 462 and one second and drive bar 463, and mobile jib 461 central authorities are hubbed on 23 of clip slots, and form the kenel of similar seesaw, its first drive bar, 462 other ends are to be provided with a pushing block 464, second drives bar 463 other ends then is provided with a pulling block 465, and its pushing block 464 is two sides that branch is located at clip slot 23 belows with pulling block 465; After aforementioned second extension rod 452 moves down, can press down the end of mobile jib 461 with respect to the first drive bar 462, and second of the other end is driven bar 463 upwards draw high, the pushing block 464 that the first drive bar 462 is connected moves down, and the pulling block 465 that the second drive bar 463 is connected moves up; Otherwise, when first drives bar 462 and 463 involutions of the second drive bar, pushing block 464 and pulling block 465 can oppositely be moved and keep in the center, therefore, when yarn feeder 3 reciprocally swingings, its pushing block 464 can promote yarn feeder 3 in regular turn and change yarn with pulling block 465.
See also Fig. 2, Fig. 3 and Fig. 4～shown in Figure 10, action flow chart when turning round for the utility model preferred embodiment, and the action schematic diagram of each step, according to said structure, during its circular knitter running, be to drive several return cams 51, an actuator 52 and several actuating cams 53 by a disk 5 to rotate synchronously, and drive transmission mechanism 4 starts of the present utility model in regular turn, the step during its start is as follows:
The 4th step 604, change yarn (two), (please consulting Fig. 7 again), and disk 5 continues to rotate, first actuation part 421 of its first driving lever 42 still is positioned at the chute 531 of first actuating cam 53, and remain on same level height, then, second actuation part 441 of its second driving lever 44, be to fall to putting in the chute 531 of one second actuating cam 53, so that second actuation part 441 of second driving lever 44, beginning moves down along with chute 531 shapes of second cam 53, and second extension rod 452 of interlock second follower lever 45 presses down mobile jib 461.
The 5th step 605, change yarn (three), (please consulting Fig. 8 again), along with second actuating cam 53 drives second driving lever 44 in regular turn, and second follower lever 45 can press down mobile jib 461 1 ends when moving down, and make second to drive bar 463 and pulling block 465 risings, and pulling block 465 1 sides also interconnect with the hook portion of yarn feeder 3 one sides, and risen by a schlagblech 7 of below, and yarn is placed in the yarn feeding mouth 8.
The 6th step 606, change yarn (four), (please consulting Fig. 9 again), when its second drive bar 463 rises, can drive pulling block 465 rises and interlock yarn feeder 3 cut-out yarns, and with yarn by decontroling (this process is called yarn cutting again) on the yarn feeder 3, its yarn one end is pressed in the yarn feeding mouth 8 by schlagblech 7, so that carry out yarn feeding by yarn feeding mouth 8.
The 7th step 607, change yarn (five), (please consulting Figure 10 again), after it decontroled yarn, because second actuation part 441 of second driving lever 44, still chute 531 shapes along with second actuating cam 53 moved, and second follower lever 45 is risen gradually, therefore, its second drive bar 463 will descend gradually, up to pulling block 465 homings.
The 8th step 608, yarn feeder 3 playback, (please consulting Figure 11 again), drive first actuating cam 53 along with disk 5 rotates, make chute 531 shapes of first actuation part 421 of first driving lever 42, move up gradually along first actuating cam 53, and make the yarn feeder 3 that is connected in first follower lever, 43 1 ends, swing moves back to original position, and is returned to original state, for using next time; Therefore, the yarn work of changing each time all is through the above-mentioned steps cycle operation, switches the yarn of various different colours.
As mentioned above, the transmission mechanism of color change head of the present utility model (to call this case in the following text) is to have following advantage:
See also Fig. 2, the transmission mechanism of the color change head of this case, formed by a selector, one first driving lever, one first follower lever, one second driving lever, one second follower lever and an interlock group, and first driving lever and first follower lever, second driving lever and second follower lever are that branch is located at selector two sides, simplifying its structure, and reach the purpose of reduction color change head thickness.
Because the thickness of the color change head of use this case can be provided with more groups of color change heads below the disk of circular knitter after reduction, and increase the mouth number that uses the different colours yarn, significantly promotes its production efficiency.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
