In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 shown, a knitting device with a fast switching function includes a frame 1, and a plurality of triangular switching mechanisms 2 are arranged around the frame 1. As Figure 2As shown, the triangle switching mechanism 2 includes a base plate 3, a support member 4 and a double-sided triangle assembly 5, wherein the base plate 3 is horizontally fixed on the frame 1, the support member 4 is fixed to the base plate 3, and the double-sided triangle assembly 5 slides horizontally between the base plate 3 and the support member 4, as shown in FIG. Figure 3 As shown, the support member 4 is provided with a driving component 6 for driving the double-sided triangle component 5 to move, the base plate 3 is provided with a guide rail groove 7 for guiding the double-sided triangle component 5 to flip over, and both sides of the bottom of the double-sided triangle component 5 are provided with guide members 8 embedded in and sliding in the guide rail groove 7. The double-sided triangle component 5 can be moved horizontally by the driving component 6, and in the process of its movement, the guide member 8 and the guide rail groove 7 cooperate with each other to make the double-sided triangle component 5 flip over, thereby achieving the purpose of replacing the triangle block.

[0020] like Figure 4 As shown, the double-sided triangular component 5 includes a base plate 9, a triangular piece 1 10 and a triangular piece 2 11, wherein the triangular piece 1 10 and the triangular piece 2 11 are respectively arranged on both sides of the base plate 9, and both are respectively provided with triangular guide rails with different tracks, and the guide rail surfaces of the triangular piece 10 and the triangular piece 2 11 are arranged on the side away from the base plate 9, and only the triangular piece located on the side of the base plate 9 close to the knitting needle can guide the knitting needle. Therefore, when the double-sided triangular component 5 is rotated and turned over, the triangular piece that acts on the knitting needle will be changed, so as to achieve the purpose of changing the weaving effect. The base plate 9, the triangular piece 1 10 and the triangular piece 2 11 can be connected by bolts and nuts, so the triangular piece 1 10 and the triangular piece 2 11 can be disassembled and replaced, and the user can choose the triangular piece style on both sides of the base plate 9 according to actual needs.

[0021] like Figure 5 As shown, the guide groove 7 includes a guide groove 12, a guide groove 13, a guide groove 14 and a guide groove 15 connected in sequence, wherein the guide groove 12 is a long arc groove guiding from the left corner to the middle, the guide groove 13 is a long arc groove guiding from the middle to the right corner, and the depth of the guide groove 13 is greater than that of the guide groove 12, the guide groove 14 is a short arc groove guiding from the right corner to the middle, and the depth of the guide groove 14 is greater than that of the guide groove 13, and the guide groove 15 is a short arc groove guiding from the right corner to the middle. 5 is a short arc groove leading from the middle to the left corner, and the depth of the head of the guide side groove 15 is greater than that of the guide center groove 14. The guide side groove 15 gradually tilts from the head to the tail to a depth equal to that of the guide center groove 12, thereby forming a circular track, from the guide center groove 12 downwardly falls into the guide side groove 13, from the guide side groove 13 downwardly falls into the guide center groove 2 14, from the guide center groove 2 14 downwardly falls into the guide side groove 15, and finally from the guide side groove 15 upwardly rises back to the guide center groove 12.

[0022] like Figure 2 , Figure 4As shown in the figure, mounting holes are provided on both sides of the bottom of the substrate 9, and the guiding members 8 are arranged in the mounting holes. The guiding members 8 are set as spring pins. One end of the guiding member 8 is fixed in the mounting hole, and the other end extends out of the mounting hole. The specific structure of the spring pin is that two pin shafts are connected by a spring. Therefore, the side extending out of the mounting hole can be telescopic, so that no matter where it is in the guide groove 7, it can keep in contact with its bottom, ensuring the guiding effect. Moreover, except for the head of the first middle guide groove 12, when the depth of the other parts of the guide groove 7 changes, it is a stepped change, which can prevent the guiding member 8 from retracting, ensuring the guiding effect and preventing the double-sided triangular assembly 5 from being unable to complete the rotation and turning over.

[0023] As Figure 5 shown, the head of the second middle guide groove 14 is aligned with the head of the first middle guide groove 12. The distance between the head of the second side guide groove 15 and the head of the first side guide groove 13 is equal to the distance between the head of the second middle guide groove 14 and the head of the first middle guide groove 12, both of which are the distance between the two guiding members 8. When the two guiding members 8 are respectively located at the head positions of the first middle guide groove 12 and the second middle guide groove 14, the double-sided triangular assembly 5 is aligned with the side of the base plate 3, and the triangular pieces can guide the knitting needles. When the double-sided triangular assembly 5 is pulled backward, the two guiding members 8 will be respectively pressed and guided by the first middle guide groove 12 and the second middle guide groove 14, and respectively move to the heads of the first side guide groove 13 and the second side guide groove 15. At this time, if the double-sided triangular assembly 5 is pulled forward again, the two guiding members 8 will be respectively pressed and guided by the first side guide groove 13 and the second side guide groove 15, and respectively move to the heads of the second middle guide groove 14 and the first middle guide groove 12. At this time, the positions of the two guiding members 8 are interchanged, that is, the double-sided triangular assembly 5 realizes turning over.

[0024] As Figure 2 、 Figure 6 shown, the support member 4 includes a bottom mounting portion 16, a support portion 17, a triangular mounting portion 18 and a driving member mounting portion 19. Among them, the bottom mounting portion 16 is horizontally arranged outward and fixed on the base plate 3. The support portion 17 is vertically upward, and its height is equal to that of the substrate 9. The triangular mounting portion 18 extends horizontally toward the double-sided triangular assembly 5. The base plate 3, the support portion 17 and the triangular mounting portion 18 form a moving space for the double-sided triangular assembly 5. The driving member mounting portion 19 extends horizontally toward the side away from the triangular mounting portion 18. The driving assembly 6 is arranged on the driving member mounting portion 19. A reinforcing rib can be arranged between the driving member mounting portion 19 and the support portion 17 to ensure the support effect and strength.

[0025] As Figure 6As shown, a movable opening 20 is provided on the triangular mounting portion 18, and a pressing column 21 is fixed to the top of the substrate 9. The pressing column extends above the movable opening 20, and the pressing column 21 is located at the center of the top of the substrate 9. Since the substrate 9 moves back and forth, the two ends move along with the guidance of the guide rail groove 7, and its center will not remain aligned with the center of the triangular mounting portion 18, but will move left and right. Therefore, the movable opening 20 is provided with an appropriate width to ensure the movement space of the pressing column 21.

[0026] As Figure 6 shown, the drive assembly 6 includes a cylinder 22, a drive seat 23 and a guide bar 24. Among them, the cylinder 22 is fixed to the drive member mounting portion 19, and the output end is arranged facing the triangular mounting portion 18. The drive seat 23 slides on the triangular mounting portion 18 and is fixed to the output end of the cylinder 22. The guide bar 24 is fixed to the triangular mounting portion 18, and a fitting groove 25 that cooperates with the guide bar 24 is provided on the drive seat 23. When the cylinder 22 expands and contracts, it can drive the drive seat 23 to slide back and forth, and the guide bar 24 can play a stabilizing role when the drive seat 23 moves.

[0027] As Figure 4 、 Figure 6 shown, a pressing opening 26 is provided on the drive seat 23, and the pressing column 21 is embedded in the pressing opening 26. The pressing opening 26 is aligned with the movable opening 20. When the cylinder 22 contracts, the drive seat 23 will move backward, and drive the pressing column 21 to move backward. The substrate 9 fixed to the pressing column 21 will move backward accordingly, and will perform a half-turning action guided by the guide rail groove 7 during the movement. Then the cylinder 22 extends, driving the drive seat 23 to move forward, and finally enabling the substrate 9 to drive the entire double-sided triangular assembly 5 to move forward, and completing the other half of the turning action guided by the guide rail groove 7 during the movement, realizing the turning of the double-sided triangular assembly 5. This action can be repeated. When the cylinder 22 expands and contracts once, the double-sided triangular assembly 5 will complete one turning. The user can numerically control the air pumps and valves of each cylinder 22 according to needs, so as to turn all the double-sided triangular assemblies 5 at one time, completely change the triangular trajectory, or only turn specific double-sided triangular assemblies 5 to achieve a specific knitting effect.
