The working process of the five-position computerized flat knitting machine knitting mechanism of electromagnetic needle selection of the present invention is as follows:

When the knitting mechanism of the present invention is used for knitting, the random head of the whole knitting mechanism reciprocates on the needle bed, and the selector reset cam 12 overcomes the elastic force of the selector spring 25 to press the end of the selector into the needle groove, and the selector The film head swings to the electromagnetic needle selector 9, and the magnetic force of the electromagnetic needle selector 9 sucks the film head of the needle selector 24, and its corresponding pressed knitting needle 21 remains in a non-working state. If the electromagnets in the 4 needle selection points in the electromagnetic needle selector 9 select needles, the suction force of the electromagnetic needle selector to the 24 heads of the needle selectors will disappear, and the needle selectors on the back of the needle selector 24 will Under the action of the spring 25, the lower heel of the needle selection piece 24 is exposed from the needle groove, and is moved forward by the action of the needle selection cam 13, and the needle selection guide piece 23 is moved forward by its thrust, breaking away from the pressure of the needle selection guide piece. The downward force of the iron 30 pushes the upper heel of the needle selection guide 23 to the L ₁ , L ₂ , T ₁ or T ₂ position according to the knitting requirements. At this time, the guide 22 is released and its heel Stretch out the needle groove and move along the needle triangle, and knitting or tucking work is carried out by the knitting needle 21. During each traverse of the machine head, all knitting needles 21 are pressed into the needle bed, and each working system of the machine head makes all needle selection jacks 24 be selected four times by the electromagnetic needle selector 9, and only the selected Knitting needles work.

If the nose moves from right to left:

(1) When the needle is selected at point _C1 , the upper heel of the needle selection guide piece ₂₃ is pushed to the L1 position, and the heel of the needle guide piece 22 is exposed from the needle groove, and it rises and retreats along the needle starting triangle 1, and moves along the The guide cam 4 descends; at this time, the half-bending yarn pressing piece a20 exits the work, and the half-bending yarn pressing piece b26 moves upwards to the L ₁ needle track and enters into work; When connecting, the upper heel of the needle selection guide piece 23 will be pressed halfway into the needle groove by the half-bending yarn pressing piece b26, and the heel of the needle guide piece 22 will also be pressed halfway into the needle groove, and then along the inner layer of the bending triangle 3 Descend, as shown in Figure 3, to complete the knitting of short loops, and the needle trajectory of the knitting needle system is shown in Figure 4;

(2) When the needle is selected at point C ₂ , the upper butt of the needle selection guide 23 is pushed to the L ₂ position, the butt of the needle guide 22 is exposed from the needle groove, and it rises and retreats along the needle starting triangle 1, and moves along the The guide cam 4 and the outer layer of the yarn bending cam 3 descend to complete the knitting of long loops, and the needle trajectory of the knitting needle system is shown in Figure 5;

(3) When the needle is selected at point C ₃ , the needle selection guide 23 is pushed to the T ₁ position, the butt of the needle guide 22 exposes the needle groove, and rises along the needle starting triangle 1; at this time, the half-bent yarn pressing plate c27 exits When working, the half-bending pressing plate d28 and the tuck pressing plate a7 move up to the T ₁ needle track and enter into work; when reaching the tuck height, the tuck pressing plate a7 acts on the butt of the needle selection guide 23 perpendicular to the surface of the needle bed, The slider 22 is pressed into the needle groove again and no longer rises along the needle raising cam 1. After passing through the tuck platen a7, the butt of the slider 22 is exposed to the needle groove again. When the yarn triangle 3 is connected, the upper heel of the needle selection guide piece 23 will be pressed halfway into the needle groove by the half-bent yarn pressing plate d28, and the heel of the needle guide piece 22 will also be pressed into the halfway of the needle groove correspondingly, and then along the curved The inner layer of the yarn triangle 3 descends to complete short loop tuck knitting. The needle trajectory of the knitting needle system is shown in Figure 6

(4) When selecting the needle at point C ₄ , the needle selection guide piece ₂₃ is pushed to the T2 position, the butt of the needle guide piece 22 exposes the needle groove, and rises along the needle starting cam 1; at this time, the tuck pressure plate b29 moves upward _Go to T2 needle track and start working; when the tuck height is reached, the tuck pressure plate b29 acts on the butt of the needle selection guide piece 23 perpendicular to the surface of the needle bed, and the needle guide piece 22 is pressed into the needle groove again, no longer along the The starting cam 1 rises, and after passing through the tuck platen b29, the butt of the slider 22 re-exposes the needle groove, descends along the outer layer of the bending cam 3, and completes the long coil tuck knitting. The needle movement track of the knitting needle system is as follows: Figure 7 shows.

(5) When the above four points (C ₁ , C ₂ , C ₃ , C ₄ ) do not select needles, the electromagnetic needle selector 9 keeps sucking the head of the needle selector 24 so that the lower heel of the needle sinks into the needle groove, If the needle selection cam 13 does not go up, the corresponding needle selection guide 23 is still at the N position, and its upper heel is pressed into the needle groove by the needle selection guide weight 30, and the corresponding heel of the needle selection guide 22 also sinks into the needle groove. (As shown in Figure 1), if it does not rise along the needle raising triangle 1, its corresponding knitting needle does not participate in work, and the needle movement track of the knitting needle system is shown in Figure 8.

When the knitting mechanism is performing transfer work, it is assumed that the machine head moves from right to left, taking needle selection at C ₂ and C ₃ as an example:

The tuck pressing plate group quits work, and the half-bending yarn pressing plate group also quits working, and the looping ring pressing plate 8 moves down to the T ₁ needle track position, and enters into work, the yarn bending triangle 3 on the left drops to the lowest position, and the yarn bending triangle 3 on the right 3 Lift up to a higher bending position; during transfer knitting, the selector selects needles at point C ₂ , and the slider 22 corresponding to the selected selector 24 is along the outer surface of the bending triangle 3 on the left Rise to the transfer height, so that the loops held by the corresponding knitting needles are placed on the transfer springs of the knitting needles, and the loops are transferred to the corresponding knitting needles on the opposite needle bed, and then pressed back to the original position by the bending triangle 3 on the right The starting position of the needle is completed, and the transfer work is completed. The needle trajectory of the knitting needle system is shown in Figure 9. When connecting the ring, the needle selection piece 24 selects the needle at C ₃ , and the upper heel of the needle selection guide piece 23 advances along the left side of the extension ring pressing plate 8. After the left side connecting ring presses the 8 plate, the needle guide piece 22 is released, and the The heel is exposed from the needle groove, and rises to the height of the loop along the loop extension triangle 2, so that the needle head just enters the transfer spring piece of the corresponding knitting needle 21 on the opposite needle bed, accepts the coil transferred from the corresponding knitting needle on the opposite needle bed, and then the right loop is connected Pressing plate 8 re-acts on the upper heel of needle selection guide 23, so that the heel of slider 22 sinks into the needle groove again; The needle guard cam 5 is pressed to the initial position to complete the work of the loop extension, and the needle movement trajectory of the knitting needle system is shown in Figure 10.
