The cutter 902 then cuts off one end of the connecting line d, and then uses the hot melt effect generated by the ultrasonic vibrator 908 to heat-glue the cut line. Another cutting cylinder 901 also cuts off the other end of the connecting line d through the above steps, and then uses the hot melt effect generated by the ultrasonic vibrator 908 to heat-glue the cut line. After two cuttings by the cutter 902, the connecting line d between the two adjacent pieces of cloth c is completely cut off, and the two adjacent pieces of cloth c are separated.

[0060] Working principle: In specific implementation, after the cloth enters the cloth feeding frame 102, the disc cutter 103 cuts off the clamped cloth, and the cloth pulling assembly 4 moves forward to pull the cut cloth and move backward. When it moves to the appropriate position, the cloth is released.

The label delivery mechanism 11 on the auxiliary frame 3 moves the label to the designated place on the cloth, and the conveying mechanism 10 moves the labeled cloth to the synchronous belt conveying mechanism 7. The synchronous belt conveying mechanism 7 presses and conveys the edge of the cloth to the overlock machine 6, and the overlock machine 6 then overlocks the edge of the cloth. After the overlock is completed, the cloth is moved to the tangent hot-gluing mechanism 9, and the connecting line of the two adjacent pieces of cloth is cut off by the tangent hot-gluing mechanism 9, and then the cut line on the cloth is hot-glued.
