Printing device for optical fiber cable sheath

Abstract

The invention discloses a printing device for optical fiber cable jackets. The printing device comprises a base, a fixed seat, a tension regulating air cylinder, a hot embossing wheel, ink ribbon mounting reels, a lifting plate and a translation plate, wherein ink ribbons are wound on the ink ribbon mounting reels; the hot embossing wheel and a plurality of pinch rollers are mounted on the front surface of the translation plate; a rotary servomotor for driving the hot embossing wheel to rotate is mounted on the surface, opposite to the hot embossing wheel, of the translation plate; the translation plate is located in front of the lifting plate; two linear rails allowing forward and backward travelling are parallelly arranged on the upper surface of a bottom plate of the lifting plate; two sliding blocks are arranged on the lower surface of the bottom plate of the translation plate; the two linear rails are embedded in the grooves of the two sliding blocks respectively; the tension regulating air cylinder is vertically mounted on the base; a cylinder barrel of the tension regulating air cylinder is fixed on the base; and the tail end of a piston rod of the tension regulating air cylinder is connected to the bottom plate of the lifting plate. The hot embossing device provided by the invention can emboss clear and durable print content on the surface of an optical fiber cable jacket, and the print content is complete, durable and clear; and elastic pressure causes no indentation in the surface of the optical fiber cable jacket, so that the product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of thermal embossing devices, in particular to a printing device for optical fiber cable sheaths. Background technique [0002] At present, the method for marking the surface of the wire and cable sheath in the domestic market is generally through two methods of inkjet printer printing or single-line embossing of the printing wheel. The disadvantage of using spray printing is that the printed marking content is easily wiped off after the wires and cables are rubbed by transportation bumps, laying dragging and other links, and the printing content has poor adhesion. The disadvantages of using the single-line embossing form of the printing wheel are: (1) Restricted by factors such as the roundness of the wire and cable and the positioning stability during the production of the wire and cable, it is easy to appear unclear printing; (2) Due to the unilateral impact of the wire and cable sheath The force will cause the th...

The disadvantage of using spray printing is that the printed identification content is easily wiped off after the wires and cables are rubbed by transportation bumps, laying and dragging, and the printing content has poor adhesion

The disadvantages of using the single-line embossing form of the printing wheel are: (1) Restricted by factors such as the roundness of the wire and cable and the positioning stability during the production of the wire and cable, it is easy to appear unclear printing; (2) Due to the unilateral impact of the wire and cable sheath The force will cause the thickness of the sheath at the embossed part to become thinner, or even crushed, resulting in product quality accidents; (3) After the actual laying of the wire and cable, if the printed content is laid below, it is easy to cause the phenomenon that the wire and cable model specification is not convenient to check

The above two marking forms have adverse effects on the manufacture, laying-out construction and later maintenance of wires and cables.
