Problems solved by technology

In the existing thermal printing process, single-line thermal printing is generally used. For cables with large diameters, when multiple lines of characters need to be thermally printed, repeated processing is required, the processing procedures are complicated, and the processing cost is high. The jump is severe, it is difficult to thermally print smoothly, resulting in blurred printing and unsatisfactory processing effect

Abstract

The invention relates to the cable processing technical field, and specifically relates to the multi-line hot stamping technology; positions needing stamping of a cable are bombarded by an ion processor, thus gasifying partial surface of the cable; an output voltage of the ion processor is 5-10kv, and an output current is 0.5-0.8A, so the surface of the cable is slightly hollowed so as to generate a rough surface, and the rough surface is easy for ink to attach, so the stamped characters are clear and tidy, and hard to remove; the cable drives stamping pinch rollers to move, thus realizing powerless driving, and saving energy; a cable motion speed is 8-12 meters per minute, and the slow speed can prevent cable jumping conditions, thus improving stable cooperation between the cable and the stamping pinch rollers; many stamping pinch rollers are employed to complete multi-line hot stamping in one process, thus saving processing steps, and improving processing efficiency.

Description

technical field [0001] The invention relates to the technical field of wire and cable processing, in particular to a multi-row thermal printing process. Background technique [0002] As the cable industry is increasing and its competitiveness is increasing, it is very important for enterprises to save and control costs. Wire and cable printing is an important link in the cable production process. The name of the factory, product model, product parameters, etc. are printed on the surface of the wire and cable to identify the type and specification information of the wire and cable. In the existing thermal printing process, single-line thermal printing is generally used. For cables with large diameters, when multiple lines of characters need to be thermally printed, repeated processing is required, the processing procedures are complicated, and the processing cost is high. The jump is severe, it is difficult to thermally print smoothly, resulting in blurred printing and unsat...
