[0036] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when in use, the electromagnetic effect of the electromagnet 20 is utilized to attract the part of the fabric carrying the needle, thereby lifting the fabric and causing the fabric to trigger the marking mechanism 19. The blocking block 1903 is lifted upward to allow the washable marking dye to mark the needle area on the warp knitted fabric.

[0037] Working principle: When the utility model is used, firstly, the warp knitted fabric is placed on the main conveyor belt 2 for conveying, and the metal detector 5 is started to detect the fabric. When a metal needle is detected, the detection signal is transmitted to the single chip microcomputer 4, so that the single chip microcomputer 4 controls the electric telescopic rod 15 to shorten, and then the flip plate 6 is flipped, so as to facilitate the warp knitted fabric on the main conveyor belt 2 to be transferred obliquely downward, so that the fabric with the needle is transferred to the second conveyor belt 14;

[0038] Secondly, when the fabric passes under the horizontal plate 13, due to the gravity of the pressing plate 17, the push switch 16 is in a triggered state, that is, the electromagnet 20 is energized, so that it generates attraction to the needle in the fabric, so that the fabric with the needle part moves upward, so that the fabric first contacts the blocking block 1903, and the blocking block 1903 moves upward, so that the discharge port 1904 is opened, so that the internal marking dye flows out to mark the area where the needle is located, and when the fabric continues to rise, it will contact the guide rod 18, so that the pressing plate 17 moves upward, so that the push switch 16 is closed, that is, the electromagnet 20 is not energized, and then the fabric falls, and is transferred to the pull-out cabinet 12 by the second conveyor belt 14 for centralized collection;

[0039] Finally, when the warp knitted fabric on the main conveyor belt 2 is qualified, its flip plate 6 remains horizontal to facilitate the transfer of the qualified fabric to the first conveyor belt 11. The position of the pressing cylinder 22 is pre-adjusted, and the electric push rod 802 is started to extend, so that the ring 804 drives the connecting rod 21 to move upward or downward along the guide groove 10, so that the pressing cylinder 22 squeezes the warp knitted fabric on the first conveyor belt 11, thereby improving the flatness of the warp knitted fabric and improving the fabric quality.
