Description
Technical field
The present invention relates to flat braiding machine, more specifically to a kind of triangle mechanism for needle selection of flat knitting machine.
Background technology
Flat braiding machine can have lopping, tuck, barring-on, not weave four kinds of woven condition in the braiding of each row.The various braiding flower type of flat braiding machine braided fabric is realized by any combination of above-mentioned four kinds of woven condition of knitting needle.And the woven condition of knitting needle is by the flower determining positions of matrix in needle tray, generally spends matrix to have B, H, A three gears to put in needle tray from low to high, is in which gear to put, and is mainly controlled by selection piece rise cam and the selection piece triangle that resets.The inclined-plane pushing and pressing selection piece rear panel heel of needle selecting cam makes on the selection piece and moves, and promotes the flower matrix by sheet heel under the selection piece again and moves to H position or A position from the B position; The reset inclined-plane pushing and pressing selection piece anter heel of triangle of selection piece makes selection piece be displaced downwardly to the B position from original A position or H position.And resetting of flower matrix is to be finished by the flower matrix triangle that resets.
See also Fig. 6, in this system for weaving, selection piece 20 and flower matrix 30 primary position when each row braiding beginning is that the lastrow braiding finishes needle selection device 41 decisions of back by a back side of arranging by the pin heel direction of motion.Among the figure, selection piece 20 and flower matrix 30 are in the H position at each row braiding initial stage.As the head right lateral, when pin is called in person relative left lateral, selection piece anter heel 22 be subjected to selection piece reset inclined-plane 12 on the triangle 12 ' pushing and pressing, be moved downward to the B position, and the flower matrix does not reset, and still keeps original H position.But flower matrix heel 31 relative left lateral will reset by the colored matrix on right side during triangle 2 regional, in order to allow colored matrix heel 31 pass through, the flower matrix triangle 2 that resets is to make the active type triangle that cam base plate 10 relatively moves up and down, when flower matrix heel 31 is passed through, the flower matrix triangle 2 that resets sinks to the cam base plate downside and (is in the next, dotting among Fig. 6), allow it pass through.As carrying out the barring-on braiding, inclined-plane 15 on the selection piece rise cam 15 on right side ' make progress to selection piece rear panel heel 21 pushes against at this moment, selection piece rise cam 15 (is in upper so must be higher than cam base plate 10, representing among Fig. 6), move on the selection piece 20 and promote to move to the A position on the flower matrix by following sheet heel 22 with solid line.After this, selection piece needle selection reset the inclined-plane 11 of triangle 11 ' effect under move down and reset to the B position, and the flower matrix continues in the A position, up to covering knitting zone 40, under resetting the pushing and pressing of triangle 2, flower matrix in left side is returned to the B position, reset inclined-plane 2 on the triangle 2 ' must be to flower matrix heel effect of this moment left side flower matrix, therefore the flower matrix leading flank that triangle 2 is higher than cam base plate 10 that resets promptly is in upper (representing with solid line among Fig. 6).Selection piece 20 is covered knitting zone 40, and pin heel thereafter 21 will be by the zone of left side selection piece rise cam 15, and same selection piece rise cam 15 also is active, can do moving up and down perpendicular to cam base plate.When selection piece rear panel heel 21 by the time, selection piece rise cam 15 moves down (be in the next, dotting among Fig. 6), allows it pass through.
