During use, can the first Spring sheet clip line mechanism 3 be set flexibly according to the specification and the material of the yarn of need clamping, the second Spring sheet clip line mechanism 4 works independently or works simultaneously, reduces unnecessary energy waste.Certainly for guaranteeing work quality and product percent of pass, all adopt operating type simultaneously.
During work, CD-ROM drive motor 53,54 is by tooth bar 661,671 corresponding with it, drive the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 moves upward, the line yarn of its top just in time slips into the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 along the filter wire casing 34,44 on it, 34,44 pairs of described yarns of this filter wire casing are online carries out foreign bodies removal, avoids the foreign matter accumulation and stops up or influence the normal operation of the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4.When the interlock plate on the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 332,432 is conflicted limited post corresponding with it 335,435, thereby make its corresponding holder 33,43 stop to move upward; At this moment, under the continuation of drive plate 31,41 drives, divider on the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 continues to move upward, cooperate down by the arc-shaped through-hole on chute on it 351,451 and the holder 33,43 331,431, force shell fragment clip 32,42 to realize the action of clamping yarn.After clamping finished, promptly the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 moved forward to the precalculated position, position induction device induction 662,672 corresponding with it, and be fed back to described power packages 5, CD-ROM drive motor 53,54 quits work; Meanwhile, the trigger 392,492 on the positioner 39,49 corresponding with it catches on interlock plate 332,432 corresponding with it just, thus the action that makes the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 continue to keep the clamping yarn.
CD-ROM drive motor 52 starts, driving thread cutting mechanism 2 by tooth bar 651 corresponding with it moves upward, equally, the line yarn of its top just in time slips into thread cutting mechanism 2 along the filter wire casing 24 on it, this filter wire casing 24 once more to yarn online carry out foreign bodies removal, thoroughly avoided the foreign matter accumulation and stopped up this class problem; When the interlock plate on the thread cutting mechanism 2 232 is conflicted limited block 235 corresponding with it, thereby make its corresponding holder 23 stop to move upward; At this moment, under the drive of drive plate 21, the divider on the thread cutting mechanism 2 continues to move upward, by the chute on it 231 and arc-shaped through-hole 251,261 cooperate down, force scissors 22 to realize the action of cutting off yarn.Cut off after action finishes, promptly thread cutting mechanism 2 moves up to the precalculated position, position induction device corresponding 652 inductions with it, and be fed back to described power packages 5, CD-ROM drive motor 52 quits work; At this moment,, under the pulling force of back-moving spring 233, realize resetting at divider; Thread cutting mechanism 2 begins to move downward under the gravity effect simultaneously, is retracted into minimum point.Repeat above-mentioned steps once, promptly thread cutting mechanism 2 repeats twice trimming action, guarantees that yarn money is errorless to cut off, and improves work quality and product percent of pass, is beneficial to the enhancing Enterprises'Competitiveness.
Cut off after action finishes, when need decontroling yarn, CD- ROM drive motor 53,54 is by tooth bar 661,671 corresponding with it, drives the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 moves downward; In the process that moves downward, the trigger 392,492 on the positioner 39,49 corresponding with it breaks away from automatically, and the first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 begin to realize decontroling the action of yarn.The first Spring sheet clip line mechanism 3, the second Spring sheet clip line mechanism 4 continue to move downward, until minimum point, and position induction device 662,672 inductions corresponding with it, and be fed back to described power packages 5, CD- ROM drive motor 53,54 quits work; Promptly finished whole Yarn clamping and cutting process; Repeat above step and just can realize cyclic production.
As described in the above embodiment of the present invention, adopt technical characterictic same or similar and other Yarn clamping and cutting method and the device that obtain, all in protection domain of the present invention with it.
