The invention discloses a fully-automatic high-speed bag making
machine which comprises a stand and a transmission device, wherein a feeding device, a
cutting-off and sealing device and a
notching device are sequentially arranged on the stand. The fully-automatic high-speed bag making
machine is characterized in that the feeding device comprises a motor, a frame and a film conveying mechanism; a feeding roll is connected to an output shaft of the motor, the feeding roll is in contact with a film coil on the frame when in a working condition, the film conveying mechanism comprises a guide roll, a floating
assembly, a linear
potentiometer, a transmission motor and a conveying roll connected with the transmission motor; the floating
assembly comprises a bracket, a floating roll and a floating roll shaft which are arranged on the bracket, the floating roll shaft is connected with the linear
potentiometer, the bracket of the floating
assembly is connected with a cylinder; and the motor and the cylinder are electrically connected with the linear
potentiometer. Through improving the feeding device, the
cutting-off and sealing device and the frame, films are conveyed stably and the advantages of better convenience, rapidness and labor-saving performance are achieved for workers during feeding and blade replacing.
