As shown in fig. 3, the knitting needle 90 includes a knitting needle 91, a long stitch 92, a spring needle 93, and a jacquard needle 94.

Referring to the station action diagram of the structuring needle 90 of fig. 4:

1) the zero position B moves along with the machine head to the right, the needle selection tail part is lifted by the needle lifting cam 6, the needle selection piece clock is exposed out of the surface of the needle bed to wait for needle selection, and the needle pushing cam 3 does not participate in the action at the moment.

2) The first H needle selection and needle non-selection have two states: if the needle is not selected, the needle is pressed into the needle groove at the right position of the tool bit of the needle selector 4 and above the selector clock, and the selector clock is not exposed out of the surface of the needle bed; if the needle is not selected, the tool bit of the selector 4 swings to one side and does not contact with the selector clock, the needle selection is kept in the original state, and the needle selection is started. The selected needle pressed into the needle groove can not rise along the jacquard triangle 5 and is at the zero position B; the selector that is not pressed into the needle groove rises along the cam 5, and the pogo pin 93 moves from the zero position B to the first position H.

3) Second position A moves leftwards when the machine head is reversed, the selected needle is selected again, the needle pushing cam 3 enters into work and acts on the selected selector clock to push the spring needle 93 from the first position H to the second position A.

As shown in fig. 5 to 10, the needle selection principle of the cam plate 100 of the computerized flat knitting machine of the present invention is as follows: the computerized flat knitting machine can make the knitting needle 91 achieve three working states of knitting, tucking and non-knitting in one row. The three working states are realized according to the position zero position B, the first position H and the second position A of the spring needle 91 corresponding to each knitting needle 91 and the movement positions of the non-woven pressing sheet 7, the connecting ring pressing sheet 20 and the collecting ring pressing sheet 13. In the whole working process, needle selection is the key; generally, the multi-station knitting function is realized through twice needle selection. One system is provided with two sets of needle selectors 4, and the previous knitting stroke needs to be pre-selected for the next knitting stroke. When the machine head moves from left to right, the first needle selecting system can perform first needle selection for knitting of the first looping system in the next stroke, the selected needle selection ascends along the jacquard triangle 5 on the left, and the corresponding spring needle 93 is pushed to the first position H from the zero position B; when the next stroke machine head runs from right to left, the first system selects the needle for the second time, the selected needle preselected by the first needle selecting system in the previous stroke is selected again, and the selected needle is further increased by one step along the left needle pushing cam 3, so that the second position A is reached. Those needles that are not selected will neither rise along the cam 5 nor along the pusher cam 3, with the pogo pin 93 in the zero position B.

The multi-station weaving principle is as follows:

1) non-woven needle trace plot: when the selected needle is not selected, the spring needle 93 is in a zero position, the clock piece of the spring needle 93 is pressed into the needle groove by the non-woven pressing piece 7, the clock piece below the long needle foot 92 in the corresponding needle groove is also pressed into the needle groove, the clock piece below the long needle foot 92 does not act with the dish mountain 12, and the knitting needle 91 is in an initial position and does not enter a knitting track.

2) Looping and needle-walking track diagram: the needle-turning cam 9 retracts into the cam bottom plate, when the selected needle is selected for the second time, the needle-pushing cam 3 pushes the selected needle to the highest point, the corresponding spring needle 93 is pushed to the second position A by the selected needle, the long needle foot 92 in the corresponding needle groove is not pressed into the needle groove, so that the knitting needle 91 is driven to rise to the looping height along the dish mountain 12, then rises along the knitting cam 11 to finish looping back, and then falls along the stitch cam 10 to finish knitting. The corresponding needle selection is returned to the initial position along the jacquard cam 5 and the push cam 3.

3) Tucking stitch trajectory diagram: the needle-turning cam 9 and the left and right loop-connecting pressing sheets 20 are retracted into the cam bottom plate, the selected needle selected for the first time rises along the jacquard cam 5, and the spring needle 93 is pushed to enter a first position H from a zero position B; the pogo pin 93 in the first position H passes the tuck tab 13 and the tabs on the pogo pin 93 are pressed into the pin grooves. Therefore, after the corresponding long stitch 92 drives the knitting needle 91 to rise to tuck height along the dish mountain 12, the lower piece clock of the long stitch 92 is also pressed into the needle groove, and the long stitch 92 does not rise along the track of the dish mountain 12 any more, but keeps descending along the stitch cam 10 at the tuck position, thereby completing tuck knitting.

4) A transfer needle trace diagram: the knitting cam 11 and the tucking presser 13 are retracted into the cam base plate, and the needle-turning cam 9 enters a working state. The selected needles on the two times rise along the needle pushing cam 3 to push the corresponding spring needles 93 to the second position A, after the corresponding lower piece clock of the long needle foot 92 drives the knitting needles 91 to rise to the tucking height along the dish mountain 12, the upper piece clock of the long needle foot 92 rises along the needle turning cam 9 again, and then the needle turning cam 9 and the sharp mountain 19 form a track to climb to complete the loop splicing, and then the needle turning cam moves to the initial position along the protection mountain.

5) Joint stitch and needle walking track diagram: the knitting triangle 11 and the tucking presser 13 are retracted into the triangle bottom plate, the selected needle selected for the first time rises along the jacquard triangle 3 to push the spring needle 93 from the zero position B to the first position H, if the selected needle is not selected for the second time, the spring needle 93 at the first position H is pressed into the needle groove when going to the tucking presser 20, and the lower clock of the corresponding long stitch 92 is also pressed into the needle groove and cannot rise along the dish mountain 12; when the spring needle 93 passes through the tucking presser 13 and is released, the lower piece clock of the corresponding long stitch 92 is also released, the long stitch 92 runs to the tucking height along the inclined plane tucking triangle processed on the dish mountain 12, then the upper piece clock of the long stitch 92 descends along the inclined plane of the needle-turning triangle 9 to complete the tucking, and then runs to the initial position along the hill-protection.

6) The state schematic diagram of the tight hanging needle moving: after the selected needle is selected and initially selected, a lower mountain protection 8 guide needle triangle pushes a selected needle belt spring needle 93 to carry, at the moment, needle receiving pressing sheets on two sides do not work, a mesh hanging pressing sheet is in work, the spring needle 93 pushes a long stitch 92 into the initial section of a knitting track, an adjustable hanging mountain protection 14 and a stitch number value are set, the stitch of the spring needle 93 and the stitch of the long stitch 92 are controlled by the stitch moving track of the adjustable hanging mountain protection 14, and tight hanging knitting is formed.

The above disclosure is only a preferred embodiment of the present invention, and the scope of the claims of the present invention should not be limited thereby, and all the equivalent changes made in the claims of the present invention are intended to be covered by the present invention.
