[0013] Compared with the prior art, the beneficial effect of the utility model is that when the automatic cloth-feeding mechanism is in use, the cloth can be passed through the connecting frame, and then the pulley is driven to rotate by the driving motor, so that the pulley and the transmission belt drive the screw to rotate, and at the same time, the rotation of the screw will cause the screw sleeve to slide, and when the screw sleeve slides, it will push the movable rod to move through the rotating shaft, and the movable rod will push the pressure rod downward to move, and the pressure rod will press the cloth in the connecting frame, which is convenient for the user to start to limit and fix the cloth, thereby avoiding the cloth from loosening and will not affect the cloth conveying effect. This is the use feature of the automatic cloth-feeding mechanism.

[0014] 1. In order to prevent the cloth from falling during the conveying process, the automatic cloth feeding mechanism can pass the cloth through the connecting frame, and drive the screw rod to rotate through the cooperation of the servo motor and the transmission belt, while making the screw sleeve slide along the screw rod, and drive the pressure rod to slide downward along the slide groove of the connecting frame through the movable rod, so that the cloth in the connecting frame can be fixed and limited, so that the cloth will not loosen and fall during the conveying process.

[0015] 2. In the process of conveying, dust will remain on the surface of the cloth. At this time, the air flow can be sprayed out through the air jet pipe through the fan and the air duct, and the half-width gear can be driven to rotate by starting the driving motor, and then the half-width gear will drive the rack to move, so as to pull the air jet pipe to move through the cooperation of the connecting block and the connecting rod.
