Surface printing device for coal mine cabtyre cables

Abstract

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.

Description

technical field [0001] The invention relates to the field of surface printing of cables, in particular to a surface printing device for rubber-sheathed cables used in coal mines. Background technique [0002] Commonly used cable printing mainly includes ink printing technology and concave-convex printing technology. Among them, ink printing is to spray a small amount of ink on the sheath in the form of characters or patterns by a printing machine, and identify it by color difference. The adhesion between the ink and the sheath is relied on, so the ink printing is easy to be sun-faded, wiped off, and smeared, especially in the harsh environment of use. Embossed printing is to print the cable information in the form of text or pattern on the sheath in the form of protrusions or grooves on the surface of the cable. This printing method is recognized by the shape change of the sheath body. The embossed characters and the sheath material have the same characteristics of wear re...
