The specific embodiment:

As shown in Figure 1, the middle mountain triangle of a kind of Computerized flat knitting machine of the utility model is fixedly installed on the cam base plate; Comprise body 10, on body 10, be provided with first track 20, second track 30, the 3rd track 40 from top to bottom, wherein: first track 20 is for turning over the pin track; First track 20 comprises the straight-line groove 8 in the middle of being arranged at; And being arranged at straight-line groove 8 two ends and the skewed slot that is connected with straight-line groove 87 is the braiding track with skewed slot 6, the second tracks 30, second track 30 is a herringbone grooves.

In the present embodiment: for making things convenient for the operation of pin bell, porch, the both sides skewed slot 7 and the skewed slot 6 of first track 20 are set to horn mouth, and herringbone grooves two side entrances of second track 30 are horn mouth.

The 3rd track 40 connects the pin track for hanging order; The 3rd track 40 is and is symmetrical set; Comprise straight-line groove 41, skewed slot 42, straight-line groove 43 compositions; Wherein: the straight-line groove 41 in left side, skewed slot 42, straight-line groove 43 are formed unidirectional track, and the straight-line groove 41 on right side, skewed slot 42, straight-line groove 43 are formed unidirectional track.

In the present embodiment; Described body 10 is to adopt split type setting; Body 10 comprises upper middle hill triangle 2, down middle mountain triangle 1, and down middle mountain triangle 1 is installed on the below of upper middle hill triangle 2, and wherein: first track 20 is arranged on the upper middle hill triangle 2; The bottom of upper middle hill triangle 2 is provided with arc groove 21; Down middle mountain triangle 1 has triangular head 11, and the triangular head 11 of down middle mountain triangle 1 is formed second track, 30, the three tracks 40 with the arc groove of upper middle hill triangle 2 bottoms 21 and is arranged on down on the middle mountain triangle 1.

The operation principle of the utility model is below described:

One, woven condition:

As shown in Figure 2, rise on the inclined-plane of second track 30 of down middle mountain, following pin heel 9 edges triangle 1, and get into the herringbone grooves of second track 30; Along with the motion of pin heel 9 down; Drive top butt 10 simultaneously and rise, during the peak of the herringbone grooves 5 of mountain triangle 1, knitting needle was in the position of moving back circle fully during pin heel instantly 9 arrived down; Then down pin heel 9 descends along the pressing face 2Q on the upper middle hill triangle 2, accomplishes pad yarn, band yarn, remains silent, knitting process such as lasso, knocking over, kinking and lopping.

As shown in Figure 3, the head traffic direction changes, and following pin heel 9 is along rising on the inclined-plane of down middle mountain triangle 1; Be introduced into the horn mouth on second track, 30 right sides; Then get into operation in the herringbone grooves,, drive top butt 10 simultaneously and rise along with the ascending motion of pin heel 9 down; When pin heel instantly 9 arrives the peak of down middle mountain triangle 1; Knitting needle is in the position of moving back circle fully, and then down pin heel 9 descends along the pressing face 2P of upper middle hill triangle 2, accomplishes pad yarn, band yarn, remains silent, lasso, knocking over, kinking and lopping knitting process.

Two, turn over the needle-like attitude:

As shown in Figure 4, top butt 10 moves under the effect of turning over the pin triangle, drives the 9 2C risings along the inclined-plane of pin heel down; Then pin heel 9 gets into straight-line groove 8 motions down, and then, following pin heel 9 continues to descend along skewed slot 7; Following pin heel 9 drives top butt 10 and descends; Then top butt 10 turns over pin and plays depressing cam decline along a left side, and pin heel 9 descends along left degree order triangle down, and needle knitting is turned in completion.

As shown in Figure 5, the head traffic direction changes, and top butt 10 moves under the effect of turning over the pin triangle; 2F rises along the inclined-plane to drive pin heel down 9, and then pin heel 9 gets into straight-line grooves 8 motions down, and following pin heel 9 continues to descend along skewed slot 6; Following pin heel 9 drives top butt 10 and descends; Then top butt 10 turns over pin and plays depressing cam decline along the right side, and pin heel 9 descends along right degree order triangle down, and needle knitting is turned in completion.

Three, connect pin, hang the order state:

As shown in Figure 6, following pin heel 9 is risen along down middle triangle 1 left side, mountain, when arriving certain altitude; Under the effect of presser feet, following pin heel 9 upper surface of mountain triangle 1 in down moves, then down pin heel 9 1E descends along the inclined-plane; And get in the left side straight-line groove 41 of the 3rd track 40, rise to straight-line groove 43 along skewed slot 42 then, when straight-line groove 43 moves to the 1B position; Withdraw from the 3rd track 40, then get into the horn mouth on second track, 30 right sides again, descend along right degree order triangle; Completion connects pin or tuck (hanging order) braiding, and top butt 10 drives next in following pin heel 9 and plays motion.

As shown in Figure 7, the head traffic direction changes, and following pin heel 9 is along rising on down middle triangle 1 right side, mountain; When arriving certain altitude, under the effect of presser feet, the upper surface of following pin heel 9 triangle 1 along down middle mountain moves; Then pin heel 9 1A declines down along the inclined-plane, and get in the right side straight-line groove 41 of the 3rd track 40, rise to straight-line groove 43 along skewed slot 42 then; When straight-line groove 43 moves to the 1D position, withdraw from the 3rd track 40, then get into the horn mouth in second track, 30 left sides; Descend along left degree order triangle, accomplish connecing pin or tuck (hanging order) braiding, top butt 10 drives next in following pin heel 9 and plays motion.

The beneficial effect of the utility model: the structure of having improved middle mountain triangle; The stability of machine lopping braiding is increased; Save some three angle transmission mechanisms and electrically drivens, improved the movement velocity of head, increased the output and the weaving quality of fabric.
