Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Referring to Figures 1 - 3 , a color-changing device for a computerized flat knitting machine, comprising a color-changing base 1, a motor mounting plate 2 is fixedly installed on the top of the color-changing base 1, four stepping motors 4 are fixedly installed on one side wall of the motor mounting plate 2, and the output ends of the four stepping motors 4 are fixedly connected with hollow shafts 11. Color-changing cams 8 are arranged outside the four hollow shafts 11. Two color-changing seesaw rods 6 are arranged below the four color-changing cams 8. Bearings 5 are arranged at one ends of the two color-changing seesaw rods 6 located below the same color-changing cam 8. Two color-changing rods 7 are arranged below the four color-changing cams 8. Magnetic members 22 are arranged inside the rotating surfaces of the four color-changing cams 8. The other ends of the eight color-changing seesaw rods 6 are respectively inserted into the slots of the eight color-changing rods 7. Zero-position sensors 3 are arranged above the four color-changing cams 8. Two mounting blocks 10 are fixedly installed at one ends of the four color-changing cams 8. Mounting holes 13 are formed in the eight mounting blocks 10. Mounting mechanisms are arranged on the four hollow shafts 11;

[0020] The mounting mechanism includes a threaded rod 9 that penetrates through and is threadedly connected to the outer wall of one end of the hollow shaft 11. One end of the threaded rod 9 located inside the hollow shaft 11 is rotatably connected to a displacement block 17. Two symmetrically arranged mounting rods 16 penetrate through the outer wall of the hollow shaft 11. Ring blocks 15 located inside the hollow shaft 11 are fixedly installed on the outer side walls of the two mounting rods 16. Springs 14 are fixedly connected between the two ring blocks 15 and the inner wall of the hollow shaft 11. Insertion cavities 21 located between the two ring blocks 15 are formed in the two ring blocks 15. Two symmetrically arranged insertion rods 12 are fixedly installed on one side wall of the displacement block 17 close to the two mounting rods 16. The mounting rods 16 are adapted to the mounting holes 13. Two guide rods 18 that penetrate through and are slidably connected to the displacement block 17 are arranged on the displacement block 17. One ends of the two guide rods 18 far from the mounting rods 16 are fixedly connected to the inner wall of one end of the hollow shaft 11. Limit blocks 19 are fixedly installed at one ends of the two guide rods 18 close to the mounting rods 16. The insertion rods 12 and the insertion cavities 21 are both right-angled trapezoidal in shape. A knob 20 is fixedly installed at one end of the threaded rod 9 located outside the hollow shaft 11.

[0021] When the utility model is in use, a magnetic member 22 is provided inside the rotating surface of the color-changing cam 8. The zero-position sensor 3 is also electrically connected to the stepping motor 4 through a wire and is used to sense the position of the magnetic member 22, so as to facilitate controlling the working state of the color-changing rod 7. The color-changing cam 8 is approximately in the shape of a circular ring tube, and its upper surface is processed into an uneven curved surface. When the bearing 5 is at the low position of the curved surface of the color-changing cam 8, the other end of the color-changing rocker 6 will lift the color-changing rod 7 upward, so that the top end of the color-changing rod 7 enters the groove of the wire seat, thereby driving the yarn nozzle on the wire seat to move left and right with the color-changing device for knitting; when the bearing 5 is at the high position of the curved surface of the color-changing cam 8, the other end of the color-changing rocker 6 will lower the color-changing rod 7, so that the top end of the color-changing rod 7 exits the groove of the wire seat and knits without the yarn nozzle.

[0022] By rotating the knob 20 to rotate the threaded rod 9, the displacement block 17 can move back and forth through the guiding of the two guiding rods 18 and the rotation of the threaded rod 9 and the displacement block 17, so that the insertion rod 12 can be inserted into the insertion cavity 21 or the insertion rod 12 can be far away from the insertion cavity 21. During the process of the insertion rod 12 being inserted into the insertion cavity 21, the inclined surface on the insertion rod 12 cooperates with the inclined surface on the insertion cavity 21, so that the two mounting rods 16 move away from each other, and the spring 14 is compressed. Furthermore, one end of the mounting rod 16 can be inserted into the mounting hole 13 on the mounting block 10, thereby realizing the fixation of the color-changing cam 8. When the insertion rod 12 is far away from the insertion cavity 21, the elastic force generated by the compression of the spring 14 can make the two mounting rods 16 move away from each other, and then one end of the mounting rod 16 moves away from the mounting hole 13 on the mounting block 10. At this time, the color-changing cam 8 can be removed from the hollow shaft 11 to complete the disassembly.

[0023] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
