Background technology
The sinker technology is continue the another much progress after using the presser feet technology on the straight-bar machines, though both play the tractive coil.But the presser feet effect is one section zone, and sinker then is configured in by each piece pin, can control old coil and new yarn on each piece pin well, can produce the stereo fabric of three-dismensional effect like this, is beneficial to out bag simultaneously, knits full fashioned knitting such as left front.All disposed sinker on current many new architectures, and configuration mode is different.As configuration is controlled sinker, and its sheet heel is controlled by a triangle track on the head, and triangle travels forward sinker, grips fabric when fabric rises, the auxiliary circle that moves back; Or when knitting needle descends rollback, for knocking over is prepared.Existing computer flat knitting machine great majority adopt the two system control technology, and promptly the Computerized flat knitting machine cam system has two tunnel braidings and connects, turns over the pin function, and the settlement triangle controlling organization has two tunnel control functions equally, is complementary with cam system.
Existing settlement triangle control structure as shown in Figure 1, each part basic function is as follows: 1 ', base: be used for assembling parts such as settlement triangle, interior draw runner, have chute on the base.2 ', pull plate: under the drive of vertical bar gear, can be along the guide rail clip move left and right.3 ', draw runner base plate: removable mounting cooperates with guide rail clip on base, is used for assembling spring leaf and bearing.4 ', vertical bar gear: combine with pull plate, but move left and right.5 ', middle cushion block: be installed on the base, be used to support pull plate, increase the stability of pull plate.6 ', spring leaf: removable mounting is between draw runner base plate and guide rail clip, and when the pull plate move left and right, spring leaf can be out of shape thereupon.7 ', pin: be packed on the draw runner base plate, be used for running in bearings.8 ', middle triangle: be packed on the base stable, transition sinker.9 ', settlement triangle: under the drive of pull plate, can move along the chute on the base is upper and lower.10 ', guide rail clip: be packed on the base, have groove, pull plate is move left and right betwixt.11 ', bearing: can rotate along pin.12 ', angle square seat (): one side is packed on the guide rail clip, and another right angle face is packed on the straight-bar machines casing.13 ', angle square seat (two): one side is packed on the guide rail clip, and another right angle face is packed on the straight-bar machines casing.14 ', interior draw runner: one side installs the draw runner base plate, and another side installs settlement triangle, can be upper and lower mobile in the base chute.
The operation principle and the shortcoming of existing settlement triangle controlling organization are: the vertical bar gear under external force, drive pull plate and do left and right reciprocating motion, pull plate promotes the upper and lower motion of bearing, bearing and draw runner base plate, interior draw runner and settlement triangle interlock are contained in the also repeated deformation thereupon of spring leaf between draw runner base plate and the guide rail clip.Because spring leaf is producing creep behind the repeated deformation many times, certain the time, easily produce fracture, when this phenomenon occurred, straight-bar machines can produce dropped stitch when assembling-disassembling, and serious meeting produces collision accident.
