When the sewn cloth is fed, the sewn cloth is connected to a cloth guide roller 721, the cloth is conveyed to a chute 722 by rotating a winding rotating disk 724, the positioning rod 7225b is clamped with movable rollers 7223, the movable buffer plate 7225a moves on the positioning rod 7225b, the sliding guide plate 7225c and the movable buffer plate 7225a are overlapped, the sliding guide plate 7225c and the movable buffer plate 7225a are matched with each other to assist the movable rollers 7223 in conveying the cloth, the cloth is prevented from sliding out between the two movable rollers 7223, the movable rollers 7223 convey the cloth to a rotating roller 7224b, the rotating roller 7224b plays a supporting role for the cloth, the friction force which hinders the movement of the cloth can be effectively reduced, the cloth is not easy to tear, the rotating roller 7224b conveys the cloth to the other end of the chute 722, the movable roller 7223 and the movable guide plate 7225c at the other end of the chute are matched with each other to wind the output of the cloth, the cloth is output by matching the movable roller 7223 and the rotating guide wheel 73, and then the output cloth is stably controlled and guided out by the guide slide block 71, so that the phenomenon that the cloth is folded to cause the reduction of sewing quality or produce defective products is prevented, and the quality of the sewn cloth is ensured.
In conclusion, by arranging the deviation correcting device, neat cloth is fixed on the convex clamping block through the rubber pad, the push rod is pushed, the buckling block slides into the connecting buckle, and the spring drives the arc-shaped buckling rod to pop out outwards, so that the arc-shaped buckling rod can be fixedly buckled with the inside of the connecting buckle, the cloth can be controlled to be sewn according to a required running path, and the sewing work efficiency is improved; set up the coiling mechanism, the cloth after the sewing passes through the rolling rotary disk and rotates to be carried on the movable roll, and the supplementary movable roll that cooperates mutually of slip baffle and removal buffer plate is carried the cloth, rotates the other end that the spout was carried to the cloth to the gyro wheel, and the movable roll and the output that the slip baffle was at the uniform velocity with the cloth roll, can realize that the cloth is difficult for appearing the fold when exporting, guarantee the quality of the cloth after the sewing.
