[0007] A knitting variable color circular flat knitting machine comprises a platform body and a knitting device and a winding device arranged on the platform body, the knitting device comprises a dial connected to the platform body through a rotating rod, a spindle clamped on the dial, a knitting track arranged on the platform body and used for the spindle to perform knitting movement, and a driving mechanism for driving the dial to rotate, the winding device is used for winding up the woven fabric, a threading plate for all yarns to pass through is arranged above the platform body, a guide rod is arranged on the rotating rod, and the end of the guide rod away from the rotating rod is close to the threading plate and is located below the threading plate.

[0008] By adopting the above technical solution, the driving mechanism drives the dial to rotate, driving the spindle to move along the weaving track, so that the yarn is wound at the intersection and weaved into a fabric. The yarn intersects under the threading plate when weaving. The setting of the guide rod can guide and restrict the yarn, reducing the probability of the yarn swinging loose due to vibration during rapid movement, thereby improving the quality of fabric weaving.

Furthermore, since the pressure roller is synchronously driven by the reduction motor, there is no need to set up an additional power source, thereby saving costs.

[0019] Optionally, it also includes a rib feeding device, which includes a rib feeding roller and a synchronous drive assembly. The rib feeding roller is rotatably connected to the platform body, and the reduction motor drives the rib feeding roller to rotate through the synchronous drive assembly.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a knitting variable color circular flat knitting machine. Figure 1 The knitting variable color circular flat knitting machine includes a platform body 1 and a knitting device 2, a yarn guiding device 3, a pressing device 4 and a winding device 5 installed on the platform body 1. Support legs 11 are arranged at the four corners below the platform body 1, and a rib feeding device 6 for conveying elastic linings such as rubber bands is installed on the support legs 11.

[0034] Reference Figure 2 The platform body 1 includes a top plate 12 and a bottom shell 13. The top plate 12 is covered on the top of the bottom shell 13, and the legs 11 are installed at the bottom of the bottom shell 13. The weaving device 2 includes a dial 21, a spindle 22, a weaving track 23 and a driving mechanism 24. There are multiple dials 21. Multiple rotating rods 25 are vertically welded and fixed on the bottom shell 13. The rotating rods 25 pass through the top plate 12. Each dial 21 is rotatably connected to the upper surface of the top plate 12 through a rotating rod 25. The driving mechanism 24 is used to drive the dial 21 to rotate. The spindle 22 is used to install the yarn roll. The spindle 22 is clamped on the dial 21. The yarn roll is not shown in the figure.

[0035] The weaving track 23 is provided on the upper surface of the top plate 12. The weaving track 23 is used as the weaving track 23 for the spindle 22 to perform weaving movement. The weaving track 23 includes a circular line track, a flat line track, and a circular flat track common track. The circular flat track common track is changed by a track change mechanism. In the embodiment of the present application, the circular line track is used as an example for explanation. Figure 1 A threading plate 71 is fixedly installed on the top plate 12 through the bracket 7. The threading plate 71 is located above the top plate 12. A threading hole 711 is opened on the threading plate 71. The projection point of the center point of the threading hole 711 on the top plate 12 is roughly located at the center of the movement trajectory of the spindle 22.

[0036] When in use, the driving mechanism 24 drives the dial 21 to rotate, and the rotation of the dial 21 drives the spindle 22 on the dial 21 to move in the weaving track 23. The spindle 22 moves between adjacent dials 21 and moves alternately along the weaving track 23, so that the yarn on the spindle 22 is entangled with each other and passes through the threading hole 711 on the threading plate 71 from bottom to top, so that the yarn is finally woven into a fabric.

[0037] Reference Figure 2The driving mechanism 24 includes a driven gear 241, a driving gear 242 and a servo motor 243. There are multiple driven gears 241, each driven gear 241 is coaxially fixedly connected to a dial 21, and the driven gears 241 are located in the cavity formed by the top plate 12 and the bottom shell 13, and the driven gears 241 are meshed in pairs. The servo motor 243 is vertically bolted and fixed on the upper surface of the top plate 12, and the rotating shaft of the servo motor 243 extends into the cavity formed by the top plate 12 and the bottom shell 13. The driving gear 242 is coaxially welded and fixed on the rotating shaft of the servo motor 243, and the driving gear 242 is meshed with one of the driven gears 241. Starting the servo motor 243 to drive the driving gear 242 to rotate can drive the driven gear 241 to rotate, thereby driving all the driven gears 241 to rotate, and then driving all the dials 21 to rotate.

[0038] Reference Figure 3 The spindle 22 will generate a large vibration during the rapid movement, so that the yarn will swing loosely during the weaving process, and the yarn will not be entangled well at the intersection, which will affect the quality of the fabric. In this regard, the yarn guide device 3 is used to guide and limit the yarn. The yarn guide device 3 includes a vertical rod 31, a guide rod 32 and a locking assembly. The bottom of the vertical rod 31 is connected to the top of the rotating rod 25 along a vertical thread, and one end of the guide rod 32 is rotatably connected to the top of the vertical rod 31. The rotation axis of the guide rod 32 is horizontally arranged, that is, the guide rod 32 swings up and down in the horizontal direction, and the locking assembly is used to lock the guide rod 32. When in use, the guide rod 32 is adjusted to the end of the guide rod 32 away from the vertical rod 31 below the threading hole 711 on the threading plate 71. When the yarn passes through the threading hole 711 from bottom to top, the guide rod 32 can guide and restrict the yarn. By properly adjusting the inclination of the guide rod 32, each yarn can always meet directly below the threading hole 711, reducing the probability of affecting the quality of the fabric due to the swinging looseness of the yarn during movement. The structure is simple and easy to use. In addition, the end of the guide rod 32 away from the vertical rod 31 is sharp, and the setting of the sharp angle can make the guide rod 32 guide the yarn more accurately.

[0039] The locking assembly includes a rotating pin 33 and a locking nut 34. A rotating hole 311 is provided at the top of the vertical rod 31 in the horizontal direction. The rotating pin 33 is inserted into the rotating hole 311. An insertion hole 331 is provided at one end of the rotating pin 33. An external thread 332 is provided on the peripheral wall of the other end of the rotating pin 33. The guide rod 32 is inserted into the insertion hole 331. The locking nut 34 is threadedly connected to the external thread 332 of the rotating pin 33. The guide rod 32 and the locking nut 34 are respectively located on both sides of the vertical rod 31. After rotating and adjusting the inclination of the guide rod 32, tightening the locking nut 34 can lock the guide rod 32 on the vertical rod 31. The arrangement of the rotating pin 33 and the locking nut 34 is simple in structure, easy to use, and the locking method is simple and reliable.

[0040] Reference Figure 1 The winding device 5 includes a winding roller 51, a reduction motor 52, a first sprocket 53, a second sprocket 54 and a first chain 55, wherein the reduction motor 52 is fixedly installed on the bracket 7 in the transverse direction, the first sprocket 53 is coaxially welded and fixed on the rotating shaft of the reduction motor 52, the winding roller 51 is rotatably connected to the bracket 7, the second sprocket 54 is coaxially welded and fixed on the winding roller 51, and the first chain 55 is wound around the first sprocket 53 and the second sprocket 54. Starting the reduction motor 52 drives the first sprocket 53 to rotate, drives the second sprocket 54 to rotate, and then drives the winding roller 51 to rotate, so as to wind up the woven fabric.

[0041] The clamping device 4 includes a clamping roller 41, a third sprocket 42, a fourth sprocket 43 and a second chain 44. Two clamping rollers 41 are provided. Both clamping rollers 41 are rotatably connected to the bracket 7 and a gap is left between the peripheral walls of the two clamping rollers 41 for only the woven fabric to pass through. The third sprocket 42 is coaxially welded and fixed to the rotating shaft of the reduction motor 52. The fourth sprocket 43 is coaxially welded and fixed to one of the clamping rollers 41. The second chain 44 is wound around the third sprocket 42 and the fourth sprocket 43. Transmission gears 45 are coaxially welded and fixed to the two clamping rollers 41, and the two transmission gears 45 mesh with each other. When in use, the woven fabric first passes between the two pressing rollers 41 and is then wound up by the winding roller 51; the reduction motor 52 drives the third sprocket 42 to rotate, and drives the fourth sprocket 43 to rotate. Due to the engagement of the two transmission gears 45, the two pressing rollers 41 rotate in opposite directions, so that the fabric passing through the threading hole 711 can be compressed, thereby improving the integrity and consistency of the fabric and improving the fabric quality.

[0042] The reinforcement feeding device 6 includes a reinforcement feeding roller 61 and a synchronous drive assembly 62. The reinforcement feeding roller 61 is rotatably connected to the support leg 11. The reinforcement feeding roller 61 is used to wind elastic linings such as rubber bands. Adding elastic linings such as rubber bands during the weaving process of the fabric can make the fabric elastic and improve the different functional requirements of the fabric. The reduction motor 52 drives the reinforcement feeding roller 61 to rotate through the synchronous drive assembly 62, so that the reinforcement feeding roller 61 can deliver reinforcement at the same rate as the winding roller 51, thereby improving the quality of the fabric. Exemplarily, in the implementation of this application, the synchronous drive assembly 62 adopts a sprocket chain transmission. The sprocket chain transmission method has been introduced above and will not be repeated here. In other embodiments, a synchronous wheel plus a synchronous belt method can also be used for transmission to achieve the purpose of synchronous movement of the reinforcement feeding roller 61 and the winding roller 51.

[0043] The implementation principle of the knitting variable color circular flat knitting machine of the embodiment of the present application is as follows: when in use, the inclination of the guide rod 32 is pre-adjusted, and then the guide rod 32 is locked by tightening the locking nut 34. The guide rod 32 can provide a better guiding and limiting effect on the yarn when it is wound at the intersection, thereby improving the quality of the fabric; start the servo motor 243, drive the active gear 242 to rotate, drive the driven gear 241 to rotate, and drive the dial 21 to rotate, so that the spindle 22 moves in the weaving track 23, so that all the yarns are woven into a fabric; start the servo motor 243 and start the reduction motor 52 at the same time, drive the reinforcing roller 61 and the pressing roller 41 to move synchronously, and the fabric with elastic lining such as rubber bands woven by the weaving device 2 passes through the threading hole 711, is compressed by the pressing roller 41, and is then wound up by the winding roller 51, and the reinforcing roller 61, the pressing roller 41 and the winding roller 51 move synchronously, thereby improving the quality of the fabric.

[0044] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
