The specific embodiment
Through specific embodiment the utility model is done further to detail below.
The automatic yarn changing unit of a kind of Ribknit cuff weft knitting circular knitting machine comprises weft-knitted circular knitting machine, and this weft knitting circular knitting machine comprises top cylinder 16, bottom cylinder 15, spout 6 and vertical shaft 4.Its innovation part is: also comprise from moving yarn and cut off mechanism and automatic yarn-feeding device.Wherein, move certainly yarn cut off mechanism by supporting vertical plate 8, organize guide more and cut off the unit and change yarn stepper motor (being positioned at the supporting vertical plate rear portion) and constitute.Supporting vertical plate is packed in the outside of top cylinder, and each guide is cut off the unit and constituted by thread-carrier 7, scissors 10, feeder cam 13 and weft cutter cam 12.The bottom that each guide is cut off thread-carrier and the scissors of unit is all cut with scissors and is contained on the supporting vertical plate, and in the middle of thread-carrier, scissors bottom, contacts respectively feeder cam and weft cutter cam are installed, and feeder cam and weft cutter cam are coaxial and by changing the yarn step motor drive.Between each thread-carrier bottom and supporting vertical plate, be connected and installed with thread-carrier extension spring 14.Between each scissors bottom and supporting vertical plate, be connected and installed with scissors extension spring 11.The position-limitting pin 9 of thread-carrier is installed on supporting vertical plate.
Cut off the unit for three groups of installing side by side change yarn in the present embodiment, be respectively and change yarn for No. one and cut off the unit, change yarn for No. two and cut off the unit and change yarn No. three and cut off the unit.That can realize three kinds of color yarns moves yarn certainly.According to actual needs, changing yarn cuts off the unit and can be two or more sets.
Automatically yarn-feeding device is made up of push jack stepper motor 1, gear train and push jack 5.The push jack stepper motor is packed on the frame 17 of weft-knitted circular knitting machine, and push jack stepper motor output shaft is installed driving gear 2, and this driving gear engagement is installed on the sector 3 that the push jack upper end installs, and this sector center is packed on the axle sleeve of weft-knitted circular knitting machine vertical shaft.Push jack is positioned at the horizontal outer fix of feed.The push jack stepper motor drives push jack around the rotation along the circumferential direction of weft-knitted circular knitting machine main shaft through gear train.
The operation principle of the automatic yarn changing unit of this Ribknit cuff weft knitting circular knitting machine is:
During initial braiding; Changing yarn for No. one cuts off the thread-carrier 18 and the scissors 19 of unit and all is in the state of lifting; Change yarn for No. two and cut off the thread-carrier 20 of unit and be in the state of lifting, scissors 21 is in to descend and compresses yarn conditions, changes yarn for No. three and cuts off the thread-carrier 22 of unit and be in the state of lifting; Scissors 23 is in to descend and compresses yarn conditions, as shown in Figure 2.When changing yarn: change yarn for No. two and cut off the thread-carrier of unit and descend, the push jack of yarn-feeding device rotates automatically, yarn is delivered to yarn feeding chew; Thread-carrier lifts, and scissors lifts, and carries out yarns No. two; Change yarn simultaneously for No. one and cut off the scissors decline of unit, a yarn is cut off and compressed, as shown in Figure 3.Once more during thread-changing: change yarn for No. three and cut off the thread-carrier of unit and descend, the push jack of yarn-feeding device rotates automatically, yarn is delivered to yarn feeding chew; Thread-carrier lifts; Scissors lifts, and carries out yarns No. three, changes the scissors decline that yarn is cut off the unit simultaneously for No. two; No. two yarns are cut off and compressed, as shown in Figure 4.Through repeating above-mentioned steps, realize the yarn weaving that changes of three kinds of yarns.Change moving 90 ° of yarn step motor drive axle revolution, realize that once changing yarn cuts off.
Although disclose the embodiment and the accompanying drawing of the utility model for the purpose of illustration; But it will be appreciated by those skilled in the art that: in spirit that does not break away from the utility model and accompanying claims and scope; Various replacements, variation and modification all are possible; Therefore, the scope of the utility model is not limited to embodiment and the disclosed content of accompanying drawing.
