The invention discloses a conductive tape conveying device which comprises a cabinet body, a tensioning wheel fixing frame and a positive and negative thread screw rod. The conductive tape conveying device is reasonable in structural design. During work, a first servo gear motor is started to drive a material collecting roller and a raw material roller to rotate, a rocking handle is used for driving a rotary disc and the positive and negative thread screw rod to rotate according to the number of personnel and stations, a first threaded sleeve and a second threaded sleeve are used for driving afirst sliding plate and a second sliding plate to move in the opposite directions, and therefore the conveying length or distance of a conveying belt can be increased through moving of a first transverse arm and a second transverse arm. Supporting guiding wheels can be used for conducting supporting guiding conveniently. A second servo gear motor is started for driving the screw rod to rotate, anup-down moving frame is used for driving the tensioning wheel fixing frame to move vertically, and therefore the tightness can be adjusted, and the failure rate of the equipment is reduced. The moving stability of the tensioning wheel fixing frame is ensured through guiding sleeves and guiding rods. In addition, the conductive tape conveying device is convenient and fast to move and place, easy and convenient to operate and easy to popularize.
