The invention discloses a voucher binding device. The voucher binding device comprises a base, a rack, a nut seat, a voucher hold-down device, a screw, a collection box, a motor, a transverse guide rail, a limiting block, a limiting switch, a connection block, an oil cylinder, a fixed block, a vertical guide rail and a perforating device. The voucher binding device is simple in structural design, low in production cost and convenient to mount; firstly, vouchers are placed on the upper surface of the movable base; a movable side plate and a baffle are arranged to effectively press and align the side surfaces of the vouchers; after that, the hold-down screw is rotated to hold down the vouchers through a pressing plate; drill jig holes are formed to bring convenience for drills to drill into the vouchers; meanwhile, the vouchers are prevented from damage; in addition, the four drills can rotationally drill into the vouchers in the same direction, so that not only is the drilling efficiency improved, but also the drilling quality is guaranteed; and at last, after drilling, the vouchers are well bound by needlework or glue.
