During operation, the warp knitted fabric to be wound passes through the inside of the support frame 12, and the warp knitted fabric is wound by the winding assembly 11. After the winding is completed, when the subsequent warp knitted fabric needs to be cut, by turning on the switch of the first cylinder 13, the first cylinder 13 drives the fixing plate 14 to move downward, so that the lowermost positioning plate 19 first contacts the warp knitted fabric, and then presses the warp knitted fabric against the surface of the cutting table 16. By continuously moving the fixing plate 14 downward, the positioning plate 19 continuously presses and fixes the warp knitted fabric located between the positioning plate 19 and the cutting table 16 under the elastic action of the compression spring 101. At this time, when the fixing plate 14 moves to a certain position, the cutting tool 15 on the fixing plate 14 cuts the warp knitted fabric in cooperation with the cutting groove 17.

During operation, by turning on the switch of the blower 6 during the winding process, the blower 6 conveys air through the air flow pipe 61 and the air vent pipe 62 into the air cavity 63, and then the air flow flows towards the surface of the warp knitted fabric through the first air outlet holes 64 and the second air outlet holes 65. By blowing air towards the surface of the warp knitted fabric, the impurities rubbed off from the surface of the warp knitted fabric by the sponge pad 5 can be blown away, further reducing the impurity residue on the surface of the warp knitted fabric, improving the protection effect on the warp knitted fabric. At the same time, by making the aperture of the second air outlet holes 65 smaller than the aperture of the first air outlet holes 64, during the blowing process, the air flow continuously blows the sponge pad 5 towards the direction close to the surface of the warp knitted fabric, thereby strengthening the cleaning effect of the sponge pad 5 on the surface of the warp knitted fabric.

After the winding is completed, when the subsequent warp knitted fabric needs to be cut, by turning on the switch of the first cylinder 13, the first cylinder 13 drives the fixed plate 14 to move downward. Then, the positioning plate 19 at the bottom first contacts the warp knitted fabric, and then presses the warp knitted fabric on the surface of the cutting table 16. By continuously moving the fixed plate 14 downward, the positioning plate 19 continuously presses and fixes the warp knitted fabric located between the positioning plate 19 and the cutting table 16 under the elastic action of the compression spring 101. At this time, when the fixed plate 14 moves to a certain position, the cutting tool 15 on the fixed plate 14 cuts the warp knitted fabric in cooperation with the cutting groove 17.

By making both ends of the warp knitted fabric tighten outward, the part of the warp knitted fabric on the cutting table 16 is made flatter, reducing the generation of wrinkles, making the warp knitted fabric more stable and flat during the cutting process, and further improving the production quality during the cutting of the warp knitted fabric by adjusting the tension of the warp knitted fabric.

[0036] By providing multiple groups of cleaning bristles 3 on the positioning plate 19, after the cutting tool 15 cuts the warp knitted fabric, by raising the fixed plate 14, the cutting tool 15 passes through the cleaning bristles 3 on both sides during the rising process, and the cleaning bristles 3 clean the fabric fibers remaining on the surface of the cutting tool 15 during cutting.

By blowing air towards the surface of the warp knitted fabric, the impurities rubbed off the surface of the warp knitted fabric by the sponge pad 5 can be blown away, further reducing the impurity residue on the surface of the warp knitted fabric, improving the protection effect on the warp knitted fabric. At the same time, by making the aperture of the second air outlet hole 65 smaller than that of the first air outlet hole 64, during the blowing process, the air flow continuously blows the sponge pad 5 towards the direction close to the surface of the warp knitted fabric, thereby strengthening the cleaning effect of the sponge pad 5 on the surface of the warp knitted fabric.
