Surface printing device for coal mine cabtyre cables

The invention discloses a surface printing device for coal mine cabtyre cables, comprising a lateral base plate, a front support plate, a rear support plate, a laser generator, a control panel, and a host. The surfaces of the front support plate and the rear support plate are respectively equipped with a pulley and two positioning wheels disposed at the two ends of the pulley, and a coal mine cable is disposed between the two positioning wheels and on the pulley. A speed measuring wheel is disposed between the front support plate and the rear support plate, and the center of the speed measuring wheel is fixed to one end of a support shaft. The other end of the support shaft is equipped with a meter counting sensor. Two guide rods are fixed to the upper end face of the lateral base plate, and a slide block sleeves the guide rods. A pressure roller and a nut are respectively fixed to the outer and inner sides of the slide block. A screw embedded into the nut is installed on a fixed plate disposed on the upper ends of the two guide rods. The surface printing device of the invention adopts a new concave-convex printing technology instead of the existing ink printing technology, and the technical problem that the existing thermal printing technology cannot be implemented on a coal mine cabtyre cable is solved. Clear, firm, durable and complete printing information on the surface of a cable is ensured.
