Description

Technical Field

[0001] The utility model relates to the technical field of flat knitting machines, and particularly relates to a novel cam plate device of a flat knitting machine. Background Art

[0002] The textile and garment industry is both a traditional industry in China and an important industry for China's economic development. As an important part of textile products, knitted products are deeply loved by consumers for their advantages such as softness, breathability, and comfortable wearing. With the development of technology, flat knitting machines have gradually replaced hand-operated flat knitting machines with their advantages such as high speed and stable quality. The cam plate structure on the head of the flat knitting machine enables the knitting needles to complete actions such as purl, grafting, knitting, and tucking. In the existing cam plates, the long needle feet move along the needle track of the cam during the tucking process. Before the long needle feet exit the cam, the spring needle feet need to be pressed into the needle groove by the tucking press piece so that the butt of the long needle feet leaves the needle track of the cam. When the spring needle feet leave the tucking press piece, the spring needle feet reset under their own elastic force so that the butt of the long needle feet exposes from the needle groove. Since the distance between the stitch density cam and the cam in the existing cam plate is small, the butt of the long needle feet often runs onto the surface of the stitch density cam when it exposes from the needle groove, resulting in friction between the butt of the long needle feet and the stitch density cam. Under long-term operation, the butt of the long needle feet is easily worn, reducing the service life of the long needle feet. Therefore, it is necessary to stop the machine to find and replace the worn long needle feet, which greatly reduces the production efficiency and increases the production cost and maintenance cost.

The cam hill 21 is fixedly arranged on the triangular base plate 1, and the purl cam 22 is telescopically arranged above the cam hill 21. Avoidance grooves 211 are respectively arranged on both sides of the cam hill 21, and the avoidance grooves 211 are connected to the needle receiving needle track on the surface of the cam hill 21.

[0043] The pressing piece unit 3 includes a left needle receiving pressing piece 31, a tuck pressing piece 32, a right needle receiving pressing piece 33, and a non-knitting pressing piece 34. The left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33 are sequentially telescopically arranged on the triangular base plate 1, and the non-knitting pressing piece is arranged below and fixedly connected to the triangular base plate 1 between the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33. In this embodiment, the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33 are of H grade, the non-knitting pressing piece is of B grade, and a knitting vacancy 35 is formed between the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33 and the cam hill, and the knitting vacancy is of A grade, so that through the cooperation of the three grades on the pressing piece unit 3 and the knitting unit 2, the knitting needle assembly can complete actions such as purling, knitting, tucking, needle receiving, and non-knitting.

[0044] Referring to Figures 3 - 5 As shown, further, a first linkage mechanism 6 is arranged between the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33. The first linkage mechanism 6 includes a push plate 61. First needle receiving guide grooves 62, tuck guide grooves 63, and second needle receiving guide grooves 64 are respectively arranged on the push plate 61. Among them, rollers are respectively rotatably arranged at the bottom of the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33 and are in sliding cooperation with the first needle receiving guide grooves 62, the tuck guide grooves 63, and the second needle receiving guide grooves 64.

[0045] A rotary driving device 7 is fixedly installed on the back of the triangular base plate 1, so as to drive the first linkage mechanism 6 to drive the left needle receiving pressing piece 31, the tuck pressing piece 32, and the right needle receiving pressing piece 33 to perform telescopic movement through the rotary driving device 7.

[0046] In this embodiment, the rotary drive device 7 preferably uses a servo motor, on the output shaft of which a gear is fixedly installed. A rack that meshes with the gear 71 is provided at the rear side of the push plate 61. And a push plate bottom plate 65 is fixedly arranged on the rotary drive device 7, and a push plate cover plate 66 is covered on the push plate bottom plate 65. First sliding grooves 67 are provided through both ends of the push plate cover plate 66, so that the push plate 61 is slidably arranged in the first sliding grooves 67. And second sliding grooves 68 are provided through the front and rear of the push plate cover plate 66, and the left needle connecting press piece 31, the hanging eye press piece 32, and the right needle connecting press piece 33 are respectively slidably arranged in the second sliding grooves 68.

[0047] Referring to Figure 5 , Figure 6 As shown in, further, in this embodiment, the first needle connecting guide groove 62 includes a first straight groove 621, a second straight groove 622, a first arc groove 623, and a second arc groove 624. The first arc groove 623 is arranged between the first straight groove 621 and the second arc groove 624, and an "S" shape is formed between the first arc groove 623 and the second arc groove 624. And the second straight groove 622 is arranged at the right end of the second arc groove 624. The second needle connecting guide groove 64 includes a third straight groove 641, a fourth straight groove 642, and a third arc groove 643. The third arc groove 643 is arranged between the third straight groove 641 and the fourth straight groove 642.

[0048] Wherein, the distance between the left end (i.e., the third straight groove 641) of the second needle connecting guide groove 64 and the front end face of the push plate 61 is greater than the distance between the left end (i.e., the third straight groove 641) of the first needle connecting guide groove 62 and the front end face of the push plate 61, and the distance between the right end (i.e., the fourth straight groove 642) of the second needle connecting guide groove 64 and the front end face of the push plate 61 is less than the distance between the right end (i.e., the second straight groove 622) of the first needle connecting guide groove 62 and the front end face of the push plate 61.

[0049] In addition, the hanging eye guide groove 63 includes a first inclined groove 631, a second inclined groove 632, and a fifth straight groove 633. The fifth straight groove 631 and the seventh straight groove 633 are respectively arranged on both sides of the sixth straight groove 632.

[0050] As Figure 5 , Figure 6 shown, when the push plate 61 is centered, the push plate at this time is in the initial state, and the roller of the left needle connecting press piece 31 is at the left end of the second arc groove 624, the roller of the hanging eye press piece 32 is at the right end of the fifth straight groove 633, and the roller of the right needle connecting press piece 33 is in the middle of the fourth straight groove 642, so that the front ends of the left needle connecting press piece 31, the hanging eye press piece 32, and the right needle connecting press piece 33 are on the same straight line.

[0051] When the push plate 63 moves to the maximum limit position to the right by 1 / 2, the left needle connecting press piece 31 and the right needle connecting press piece 33 retract into the triangular bottom plate under the linkage of the push plate, while the hanging eye press piece is still in the extended state.

[0052] As Figure 8 shown, when the push plate 61 moves to the maximum limit position to the right, the left needle receiving press plate 31 and the right needle receiving press plate 33 extend out of the triangular base plate, while the hanging eye press plate 32 retracts into the triangular base plate 1, and the distance that the left needle receiving press plate 31 extends out of the triangular base plate 1 is less than the distance that the right needle receiving press plate 33 extends out of the triangular base plate 1.

[0053] As Figure 7 shown, when the push plate 61 moves to the maximum limit position to the left, the left needle receiving press plate 31 and the right needle receiving press plate 33 extend out of the triangular base plate, while the hanging eye press plate 32 retracts into the triangular base plate, and the distance that the left needle receiving press plate 31 extends out of the triangular base plate 1 is greater than the distance that the right needle receiving press plate 33 extends out of the triangular base plate 1.

[0054] Through the above settings, the left needle receiving press plate 31, the hanging eye press plate 32, and the right needle receiving press plate 33 complete corresponding actions under the linkage of the first needle receiving guide groove 62, the hanging eye guide groove 63, and the second needle receiving guide groove 64 of the push plate.

[0055] In the traditional press plate unit, the long needle foot cooperates with the left needle receiving press plate and the right needle receiving press plate to move along the track of the dish mountain to complete the hanging eye action. However, the stroke between the traditional left needle receiving press plate and the right needle receiving press plate remains the same, and the surface height of the dish mountain is the same as the surface height of the hanging eye. Therefore, every time the long needle foot exits the dish mountain, the long needle foot resets under its own elastic action. At this time, the heel of the long needle foot exposes the needle slot and is on the surface of the hanging eye triangle, resulting in friction between the heel of the long needle foot and the surface of the hanging eye triangle. After long-term work, the heel of the long needle foot is prone to wear.

[0056] Combined with Figure 2 , Figure 7 , Figure 8As shown, to solve the above problems, in this embodiment, the retraction groove of the disc mountain is used in cooperation with the left stitch cam triangle and the right stitch cam triangle to avoid the surface friction between the sinkers of the long stitch and the stitch cam triangle. When the machine head moves from left to right, the rotary drive device drives the push plate 61 to move leftward, linking the left stitch-holding piece 31 and the right stitch-holding piece 33 to extend out of the triangle base plate 1. In this way, the knitting needle assembly 9 is pressed into the needle groove through the right stitch-holding piece 33, and the knitting needle assembly 9 moves along the needle receiving channel of the disc mountain 21. After the knitting needle assembly 9 leaves the right stitch-holding piece 33, the sinkers of the long stitch 92 gradually rise along the needle receiving channel. When reaching the left stitch-holding piece 31, the left stitch-holding piece 31 presses the long stitch into the needle groove. Since there is a certain stroke difference between the left stitch-holding piece 31 and the right stitch-holding piece 33 in this embodiment, the sinkers of the long stitch 92 are not completely sunk into the needle groove under the action of the left stitch-holding piece 31, and there are still some sinkers exposed from the needle groove, so that the sinkers of the long stitch enter the retraction groove 211 along the needle receiving channel, and the sinkers of the long stitch 92 move along the side wall of the stitch cam unit after leaving the disc mountain 21 from the retraction groove 211, rather than moving from the surface of the stitch cam triangle, effectively avoiding the friction between the sinkers of the long stitch and the stitch cam triangle and greatly improving the service life of the long stitch.

[0057] Referring to Figure 3 , Figure 4 As shown, in this embodiment, a second linkage mechanism 8 is provided between the rotary drive device 7 and the purl cam 22. The second linkage mechanism 8 includes a linkage lever 81 and a turntable 82. In this embodiment, a second linkage mechanism 8 is provided between the rotary drive device 7 and the purl cam 22. The second linkage mechanism 8 includes a linkage lever 81 and a turntable 82. The middle of the linkage lever 81 is rotatably connected to the back of the triangle base plate 1, and the turntable 82 is fixedly arranged on the top surface of the gear. And in this embodiment, both sides of the peripheral wall of the turntable 82 have a first arc-shaped convex block and a second arc-shaped convex block, and the first arc-shaped convex block and the second arc-shaped convex block are respectively in contact and cooperation with the lower end of the linkage lever 81. The back of the purl cam 22 has a connecting shaft 221, and a slot is opened on the peripheral wall of the connecting shaft 221 so that the slot of the connecting shaft 221 is engaged with the upper end of the linkage lever 81. Therefore, when the rotary drive device 7 drives the gear 71 to rotate, the linkage lever 81 swings back and forth under the action of the first arc-shaped convex block or the second arc-shaped convex block of the turntable 82, thereby linking the purl cam 22 to extend out of or retract into the triangle base plate 1, so as to cooperate with the presser unit to complete the specified knitting action.

[0058] Referring to Figure 1 , Figure 4As shown, the stitch density unit 10 includes a left stitch density cam 101 and a right stitch density cam 102. The left stitch density cam 101 and the right stitch density cam 102 are respectively arranged on both sides of the knitting unit 2. A pair of chutes are provided on the cam base plate. Sliders 104 are provided on the backs of the left stitch density cam 101 and the right stitch density cam 102, so that the sliders 104 of the left stitch density cam 101 and the right stitch density cam 102 are slidably engaged with the chutes of the cam base plate 1. And third linkage mechanisms 103 for driving the left stitch density cam 101 and the right stitch density cam 102 to slide are respectively provided on the backs of the cam base plates 1.

[0059] Combined with Figure 11 、 Figure 12 As shown, specifically, the third linkage mechanism 103 includes a swing arm 1031, a spiral disk 1032, and a stitch density driving device 1033. One end of the swing arm 1031 is rotatably arranged on the back of the cam base plate 1. A push groove 1034 is provided at the other end of the swing arm 1031. A first roller 1041 is rotatably arranged on the slider 104 and is slidably engaged with the push groove 1035. The stitch density driving device 1033 is fixedly installed on the back of the cam base plate. In this embodiment, the stitch density driving device 1033 is preferably a motor. The spiral disk 1032 is fixedly arranged on the output shaft of the stitch density driving device. The spiral disk 1032 has a spiral groove. And a second roller 1035 slidably engaged with the spiral groove is rotatably arranged in the middle of the swing arm 1031. A linkage arm 1036 is rotatably arranged in the middle of the swing arm 1031. An elastic member is provided between the upper part of the linkage arm and the swing arm 1031. A third roller 1037 is rotatably arranged at the lower part of the linkage arm 1036. The second roller 1037 is slidably engaged with the outer periphery of the spiral disk 1032.

[0060] When the stitch density driving device 1033 drives the spiral disk 1032 to rotate forward, the swing arm 1031 slides along the surface of the worm gear groove, so as to push the left stitch density cam 101 / right stitch density cam 102 to slide upward under the guiding action of the worm gear groove of the spiral disk 1032. When the stitch density driving device 1033 drives the spiral disk 1032 to rotate reversely, the linkage arm 1036 slides along the outer wall of the spiral disk 1032, so that the linkage arm 1036 drives the left stitch density cam 101 / right stitch density cam 102 to slide downward under the push of the outer wall of the spiral disk 1032. Thus, the tightness of the fabric is adjusted by the left stitch density cam 101 or the right stitch density cam 102.

[0061] Referring to Figure 1 、 Figure 9 As shown, further, the needle selection unit 4 includes a needle selector 41, a needle selection guide block 42, and a magnetic attraction mechanism 43. The needle selection guide block 42 is arranged on the cam base plate 1. The needle selector 41 is arranged above the needle selection guide block 42. The magnetic attraction mechanism 43 is arranged below the needle selection guide block 42. The needle selection guide block 42 cooperates with the needle selector 41 to select needles for the knitting needle assembly 9. The magnetic attraction mechanism 43 is used to hold the knitting needle assembly 9.

[0062] Combined with Figure 11 、 Figure 18 As shown, a needle selecting guide block 42 is provided with a needle guiding triangle 421 on one side of the top, a needle pushing triangle 422 on the other side of the top, and a zero position triangle 423 is arranged between the needle guiding triangle 421 and the needle pushing triangle 422 on the upper part of the needle selecting guide block 42. In this embodiment, the zero position triangle 423 and the selector 41 cooperate to push the knitting needle assembly to position B, the needle pushing triangle 422 and the selector 41 cooperate to push the knitting needle assembly to position A, and the needle guiding triangle cooperates with the selector to push the knitting needle assembly to position H.

[0063] Wherein, both ends of the zero position triangle 423 respectively have a guiding inclined surface 425 between the needle guiding triangle 421 and the needle pushing triangle 422, so that the lower end of the knitting needle assembly 9 moves along the upper edge of the zero position triangle 423, and under the action of the guiding inclined surface 425, the lower end of the knitting needle assembly 9 is pressed into the needle groove, so that the magnetic attraction mechanism 43 attracts the lower end of the knitting needle assembly 9.

[0064] Furthermore, in this embodiment, a thimble triangle 424 is arranged below the zero position triangle 423 in the middle of the needle selecting guide block 42, so that the thimble triangle 424 is used to cooperate with the selector to press the knitting needle assembly 9 into the needle groove.

[0065] Furthermore, the magnetic attraction mechanism 43 includes a magnetic attraction seat 431, a magnetic component 432, and a magnetic conduction component 433. The magnetic attraction seat 431 is fixedly arranged at the bottom of the triangle base plate 1. A slot is arranged on the magnetic attraction seat 431, so that the magnetic component 432 is inserted into the slot of the magnetic attraction seat 431. The magnetic conduction components 433 are a pair and are respectively arranged on the upper and lower surfaces of the magnetic component 433.

[0066] Specifically, the magnetic conduction component 433 includes a first magnetic conduction block 4331, a second magnetic conduction block 4332, and a spacer 4333. The spacer 4333 is arranged between the first magnetic conduction block 4331 and the second magnetic conduction block 4332, and copper sheets 4334 are respectively arranged between the spacer 4333 and the first magnetic conduction block 4331 and the second magnetic conduction block 4332. In this embodiment, the magnetic component 432 is preferably a magnet, so as to increase the magnetic force of the magnetic component 432 through the magnetic conduction component 433, so that the magnetic component 432 can attract the knitting needle assembly 9 without contacting the knitting needle assembly 9, thereby avoiding frequent contact between the knitting needle assembly 9 and the surface of the magnetic component 432, preventing the magnetic component 432 from generating notches due to frequent contact, effectively reducing the production cost. The spacer 4333 is preferably a metal material. In this embodiment, it is not limited to one kind of metal material, and it can also be a non-magnetic material, so that no magnetic force is generated under the isolation of the spacer 436 and the copper sheet 4334. Therefore, when the spacer 436 passes through the knitting needle assembly 9, the spacer 436 does not attract and combine with the knitting needle structure 9, so that the knitting needle assembly can cooperate with the selector according to the knitting needs.

[0067] Refer to Figure 1 、 Figure 10 As shown, the reset unit 5 includes a movable reset triangle 51 and a fixed reset triangle 52. The fixed reset triangle 52 is fixedly arranged between the movable reset triangle 51 and the disc mountain 21. One side of the fixed reset triangle 52 facing the movable reset triangle 51 has a concave position 521. One end of the movable reset triangle 51 is rotatably connected to the concave position 521 of the fixed reset triangle 52. And one side of the triangular base plate 1 is fixedly provided with an adjusting plate 53. The adjusting plate 53 has an arc-shaped groove 531, so that the other end of the movable reset triangle 51 is fixedly connected to the arc-shaped groove 531 through a locking member. In this embodiment, the locking member is preferably a screw and a nut, so that the up and down swing of the movable reset triangle 51 can be adjusted through the arc-shaped groove 531, thereby adjusting the height of the movable reset triangle 51.

[0068] Furthermore, on the surface of the movable reset triangle 52, there is a return needle bump 522 on the side facing the knitting unit 2, so that when the knitting needle assembly 9 leaves the H position of the knitting unit 2, it is blocked by the side wall of the return needle bump 522, and the knitting needle assembly 9 gradually moves down under the action of the inclined surface of the return needle bump 522 to the lower edge of the return needle bump 522, thereby retracting the knitting needle assembly to the B position.

[0069] Even further, a limit bump 523 is provided on the surface of the movable reset triangle 52 at the top of the return needle bump 522. When the knitting needle assembly 9 passes by the preselected pusher triangle 422, the knitting needle assembly 9 enters the knitting unit 2 along the surface of the return needle bump 522. At the same time, the limit bump 523 is used to limit the up and down movement of the knitting needle assembly 9, so that the needle movement of the knitting needle assembly 9 is smoother and the noise is reduced.

[0070] Refer to Figure 19 、 Figure 20 As shown, in this embodiment, the above-mentioned knitting needle assembly 9 includes a knitting needle 91, a long needle foot 92, and a spring needle selection foot 93. The knitting needle 91, the long needle foot 92, and the spring needle selection foot 93 are respectively inserted into the needle grooves of the needle bed. Among them, the lower part of the knitting needle 91 is connected to the upper part of the long needle foot 92, and the spring needle selection foot 93 is relatively arranged on the outer lower part of the long needle foot 92.

[0071] Furthermore, the spring needle selecting foot 93 includes a spring needle segment 931 and a needle selecting segment 932. The upper part of the needle selecting segment 932 is arranged at the lower outer side of the spring needle segment 931. An elastic piece 933 is arranged at the lower part of the spring needle segment 931 at the rear end of the needle selecting segment 932, so that the needle selecting segment 932 can elastically deform under an external force. A spring upper butt is arranged at the upper part of the spring needle segment 931, and a needle selecting lower butt 935 is arranged at the lower part of the needle selecting segment 932, such that the needle selecting lower butt 935 of the needle selecting segment 932 moves along the track of the needle selecting guide block 42, thereby pushing the spring needle selecting foot 93 to rise, and thus pushing the long needle foot 92 to three different working positions A, H, and B through the elastic piece 933.

[0072] Combined Figure 9 As shown, and the lower part of the needle selecting segment 932 has a clearance section 934 bent in the direction of the long needle foot 92, so that when the spring needle selecting foot 93 moves along the needle guiding triangle 421 or the needle pushing triangle 422 of the needle selecting guide block 53, the clearance section 934 of the spring needle selecting foot 93 can avoid the needle selector 41, preventing the unnecessary spring needle selecting feet 93 from being selected again or the needle selecting feet 93 that need to be preselected to the H position from being pressed into the needle groove by the thimble triangle 424 and hitting the blade of the needle selector 41, thereby greatly improving the working stability of the knitting needle assembly.

[0073] When the spring needle selecting foot moves along the needle guiding triangle, the spring needle selecting foot 93 is selected by the needle selector 41. When the needle selecting teeth of the needle selecting segment 932 pass through the needle selector 41, the blade of the needle selector 41 presses the needle selecting segment 932 of the spring needle selecting foot 93. At the same time, the lower end of the needle selecting segment approaches the surface of the magnetic component under the pressing, so that the lower end of the needle selecting segment 932 is in magnetic contact with the magnetic component 432. Therefore, the needle selecting lower butt of the needle selecting segment 932 does not rise along the track of the needle pushing triangle, but passes over the surface of the needle pushing triangle, thereby ensuring the working stability of the knitting needle assembly.

[0074] Furthermore, the upper part of the long needle foot 92 has a reinforcing piece 921, which is used to increase the strength of the upper part of the long needle foot 92 and ensure the stability of the connection between the long needle foot and the knitting needle.

[0075] Referring Figures 13 - 20 As shown, the specific working actions of the present utility model are as follows:

[0076] The needle connecting process includes the steps: after the spring needle selecting foot passes through preselection and its lower butt is at the position of the needle guiding triangle 421, when needle connecting is carried out, first, the selector 41 does not select the spring needle selecting foot 93. When the needle selecting lower butt of the spring needle selecting foot 93 passes along the top edge of the needle guiding triangle 421 through the selector 41, the tooth piece of the spring needle selecting foot 93 is pressed into the needle groove by the butt needle triangle 424, and the lower part of the spring needle selecting foot 93 is magnetically attracted to the magnetic component, so that the spring needle selecting foot 93 moves along the first track X1 of the needle guiding triangle 421, making the upper butt of the spring of the spring needle selecting foot 93 at the H position. Then, the rotation driving device drives the left needle connecting pressing piece 31 and the right needle connecting pressing piece 33 to extend out of the triangle base plate 1, and the purl pressing piece 32 retracts into the triangle base plate 1. The left needle connecting pressing piece 31 presses the spring needle section 931 of the spring needle selecting foot 93 into the needle groove, and the spring needle section 931 sinks the butt of the long needle foot 92 into the needle groove, so that the butt of the long needle foot 92 moves linearly along the surface of the cam mountain 21. When passing through the vacancy formed by the purl pressing piece 32, the spring needle section 931 of the spring needle selecting foot 93 resets, and the butt of the long needle foot 92 is exposed from the needle groove, so that the butt of the long needle foot 92 falls onto the needle connecting needle track of the cam mountain and moves along the track C1 of the needle connecting needle track. Finally, the right needle connecting pressing piece 33 partially extends out to press a part of the butt of the long needle foot 92 into the needle groove by the spring needle section 931, so that the butt of the long needle foot 92 enters the clearance groove 211 along the guiding track, so that after the butt of the long needle foot 92 leaves the clearance groove 211, it gradually descends along the side wall track of the right stitch density triangle 102, thus completing the needle connecting process for the knitting needle;

[0077] The eyelet knitting process includes the steps: After the spring selecting needle foot is preselected, its lower butt is at the position of the needle guiding triangle 421. When performing eyelet knitting, first, the selector 41 does not select the spring selecting needle foot 93. When the lower butt of the spring selecting needle foot 93 passes along the top edge of the needle guiding triangle 421 through the selector 41, the tooth piece of the spring selecting needle foot 93 is pressed into the needle groove by the butt needle triangle 424, and the lower part of the spring selecting needle foot 93 is magnetically attracted to the magnetic component, so that the spring selecting needle foot 93 moves along the first track X1 of the needle guiding triangle 421, making the upper butt of the spring of the spring selecting needle foot 93 in the H position. Then, the rotation driving device drives the left needle connecting piece 31 and the right needle connecting piece 33 to retract into the triangular base plate 1, the eyelet knitting piece 32 extends out of the triangular base plate 1, and the purl cam 22 is driven by the second linkage mechanism to retract into the triangular base plate 1. When the spring needle section 931 of the spring selecting needle foot 93 passes through the vacant position formed by the left needle connecting piece 31, the butt of the long needle foot 92 gradually rises along the side wall of the cam hill 21. When passing through the eyelet knitting piece 32, the spring needle section 931 of the spring selecting needle foot 93 is pressed into the needle groove, and the spring needle section 931 presses the butt of the long needle foot 92 into the needle groove, so that the long needle foot 92 moves along the straight track C2 on the surface of the cam hill 21. When reaching the vacant position formed by the right needle connecting piece 33, the spring needle section of the spring selecting needle foot 93 resets, and the butt of the long needle foot 92 is exposed from the needle groove and gradually descends along the side wall of the cam hill, so that the knitting needle completes the eyelet knitting process;

[0078] The knitting process includes the steps: First, the selector 41 selects the spring selecting needle foot 93. The lower butt of the spring selecting needle foot 93 passes along the top edge of the zero position triangle 423 and is pressed into the needle groove under the action of the guiding inclined plane 425, so that the lower part of the spring selecting needle foot 93 is magnetically attracted to the magnetic component 432 until the spring selecting needle foot 93 does not attract to the magnetic component 432 when passing through the spacer 436, so that the spring selecting needle foot 93 is exposed from the needle groove and the spring selecting needle foot 93 moves along the second track X2 of the pusher needle triangle 422, thereby pushing the upper butt of the spring selecting needle foot 93 to the A position, and the rotation driving device drives the purl cam 22 to retract into the triangular base plate 1, so that the spring needle foot 93 moves along the knitting vacant position, and the butt of the long needle foot 92 moves along the first knitting track C3 on the top surface of the cam hill 21, so that the knitting needle completes the knitting process;

[0079] The needle transfer process includes the steps: First, the selector 41 selects the spring needle selecting foot 93. The lower needle selecting heel of the spring needle selecting foot 93 moves along the top edge of the zero cam 423, and under the action of the guiding inclined surface 425, the spring needle selecting foot 93 is pressed into the needle groove, so that the lower part of the spring needle selecting foot 93 is magnetically attracted to the magnetic component 432 until the spring needle selecting foot 93 does not attract to the magnetic component 432 when passing through the spacer 436, so that the spring needle selecting foot 93 exposes from the needle groove and the spring needle selecting foot 93 moves along the second track X2 of the pusher cam 422, thereby pushing the upper needle selecting heel of the spring needle selecting foot 93 to position A, and the rotary driving device 7 drives the needle transfer cam 22 to extend out of the cam base plate 1, so that the spring needle selecting foot moves along the knitting vacancy, and the heel of the long needle foot 92 moves along the second needle running track C4 of the disc hill 21 and the needle transfer cam 22, so that the knitting needle completes the needle transfer process;

[0080] The non-knitting process includes the steps: First, the selector 41 does not select the spring needle selecting foot. The lower needle selecting heel of the spring needle selecting foot 93 moves along the top edge of the zero cam 423, and under the action of the guiding inclined surface 425, the spring needle selecting foot 93 is pressed into the needle groove, so that the lower part of the spring needle selecting foot 93 is magnetically attracted to the magnetic component 432, so that the spring needle selecting foot 93 moves along the third track X3 of the zero cam 423, and the upper spring heel of the spring needle selecting foot 93 is in position B. The spring needle segment 931 of the spring needle selecting foot 93 is pressed into the needle groove by the non-knitting pressing piece 34, and the spring needle selecting foot 931 sinks the heel of the long needle foot 92 into the needle groove, so that the long needle foot 93 moves along the straight track C5 on the surface of the disc hill, so that the knitting needle does not participate in knitting.

[0081] When the machine head moves to the right, its working process is the same as that when the machine head moves to the left, and this embodiment will not be repeated again.

[0082] In addition, in the non-knitting process, when the elastic needle selecting foot 93 at position B pauses in the middle of the zero cam 423, if the selector 41 does not select the spring needle selecting foot 93, the spring needle selecting foot 93 continues to be magnetically attracted to the magnetic component 432, so that when the machine head turns around, the spring needle selecting foot 93 moves along the surface of the guiding inclined surface, so that the spring needle selecting foot 93 remains at position B, or if the selector 41 selects the spring needle selecting foot 93, the lower needle selecting heel of the spring needle selecting foot 93 moves along the top edge of the pusher cam 422.
