The invention relates to a conveying, detecting and locating device for a hard sequence card. The device is used on a fully automatic dividing and cutting machine for the hard card which is made of a polyvinyl chloride (PVC) material as a representative, belongs to the field of printing and packaging machinery, and comprises a conveyor belt, a side locating plate, a front locating plate, a nozzle assembly, a side detection switch, an induced-draught belt, a front detection switch and a control system. The device overcomes the defects of low efficiency, time and labor waste and low precision due to manual card conveying of the conventional card cutting machine, implements the automatic conveying, detection, location and adjustment for the hard sequence card, is fast and precise in action, and can obviously improve the working efficiency and effectively improve the process precision of conveying the card, so as to ensure the dividing and cutting qualities, avoid manual card conveying and location, and liberate the productivity. The device can also be used for the automatic conveying, detection, location and adjustment of the hard card made of a non-PVC material or a common paper card.
