The cylindrical fabric is split into a single layer of fabric by using an electric cutter. The process is troublesome, the driving mechanism of the cutter not only costs a certain amount of money, but also has a certain safety risk during operation, and has further improvement space.

A support base 2 is fixedly connected to the center of the lower inner side of the circular knitting machine base 1, a rotating frame 3 is rotatably connected above the support base 2, a winding frame 4 is fixedly connected to the center of one side of the rotating frame 3, a roller frame 14 is fixedly connected to the upper inner side of the rotating frame 3, three pressure rollers 15 are rotatably connected to the roller frame 14, and a first connecting arm 5 and a second connecting arm 6 are fixedly connected to both sides above the rotating frame 3. The tops of the first connecting arm 5 and the second connecting arm 6 are fixedly connected to the bottom of the knitting device. Together with the existing transmission mechanism, they can form a winding device for use in a circular knitting machine.

[0026] An adjusting plate 9 is fixedly connected to the inner side of the upper part of the first connecting arm 5. An adjusting groove is opened in the middle of the adjusting plate 9. A telescopic rod 8 is rotatably connected to the middle of the adjusting plate 9. A fixing screw passing through the adjusting groove is set on the telescopic rod 8 at the position corresponding to the adjusting groove. A positioning screw for length positioning is set on the body of the telescopic rod 8. A transverse top rod 10 is vertically fixedly connected to the end of the telescopic rod 8 away from the adjusting plate 9. Through the cooperation of the adjusting plate 9 and the telescopic rod 8, the up and down position and pressure of the transverse top rod 10 can be flexibly adjusted. The telescopic rod 8 and the transverse top rod 20 set on the first connecting arm 5, together with the adjusting plate 9, can push the originally cylindrical fabric out of the cutting direction to a plane, so that the fabric tends to move to both sides of the blade due to tension, which makes it easier for the slitting blade 13 to cut the fabric.

[0027] A cutter holder 11 is provided below the middle frame 7. The upper part of the cutter holder 11 is fixedly connected to the bottom of the knitting device, and the fixing point is located on the line connecting the fixing positions of the first connecting arm 5 and the second connecting arm 6. A cutter fixing seat 12 is fixedly connected to the lower end of the cutter holder 11 near the adjusting plate 9. A slitting cutter 13 is fixedly connected obliquely above the cutter fixing seat 12. A roller is rotatably connected to the end of the cutter fixing seat 12 near the first connecting arm 5. By setting the cutter holder 11 and the cutter fixing seat 12 inside the tubular fabric below the middle frame 7, the cutter 13 can be integrated above the winding device. When the winding device of the circular knitting machine is winding, the cutter 13 can directly slit the side of the tubular fabric by utilizing the winding tension of the winding device itself.

[0028] Working principle: This utility model integrates the slitting blade 13 above the winding device by setting the blade fixing frame 11 and blade fixing seat 12 on the inner side of the tubular fabric below the middle frame 7. When the winding device of the circular knives is winding, the slitting blade 13 directly cuts the side of the tubular fabric using the winding tension of the winding device itself. At the same time, the first connecting arm 5 is equipped with a telescopic rod 8 and a transverse push rod 20, which, together with the adjusting plate 9, can push the originally tubular fabric out of the cutting direction to create a plane. Due to the tension, the fabric tends to move towards both sides of the blade, making it easier for the slitting blade 13 to cut the fabric and improving processing efficiency.
