Problems solved by technology

However, the printing equipment of this method is relatively expensive, so there is no manufacturer in my country to officially purchase and use this printing machine.
[0004] Some domestic manufacturers use the high temperature of the gas tank to burn and then use the high temperature ink printing wheel to print, but this method of printing is dangerous and extremely unsafe

Embodiment Construction

[0018] Such as figure 1 As shown, firstly, the fluoroplastic wire to be printed is preheated to the optimum temperature and time in the electric heating preheater, which requires controlling the speed of the wire walking in the preheater, and the speed generally depends on Depending on the diameter of the wire, we use stepless speed regulation to control the running speed of the wire. Usually, the speed of the wire is 30-50 m / min;

[0019] Then the wire runs on the printing wheel of high-temperature ink to print, and then the wire enters the electric heater for heating. After heating, the printing should be firm and clear, which requires that the heating temperature range should be just right, the temperature range is 450°C±20°C, so the power of the electric heater is also very important, and finally the wire can be cooled to complete the printing (put The printed electric wire is received on the take-up spool again).

[0020] Experiments have proved that the preheating temp...

Abstract

The invention provides a fluoroplastic electric wire and cable surface lettering method. The method comprises the following steps of: preheating a fluoroplastic electric wire in an electrical heating preheater, lettering on a high-temperature printing ink lettering wheel, heating the lettered electric wire in an electric heater, cooling the electric wire and the like. The invention also provides a corresponding lettering device which comprises a paying-out mechanism, the electric preheater, a high-temperature printing ink roll wheel lettering machine, the electric heater, a cooling mechanism and a cable coiling mechanism through which the electric wire successively passes. The method has the beneficial effects that the fluoroplastic surface of the electric wire is preheated to a required temperature firstly, then lettering is carried out on the fluoroplastic surface of the electric wire by use of high temperature printing ink, then the lettered fluoroplastic surface of the electric wire is heated to the required temperature so as to be firmly adhered to the fluoroplastic surface of the electric wire and cable, and subsequently, and cooling is performed, so that the lettering is firm and clear, the price is economic and cheap. Thus, the method and device provided by the invention are suitable for national conditions of China.

Description

technical field [0001] The invention belongs to the field of wire and cable processing, and in particular relates to a method and a device for printing on the surface of a wire and cable whose surface insulating layer is fluoroplastic. Background technique [0002] Due to the acid and alkali resistance, excellent chemical stability, and non-adhesive properties of fluoroplastics, it is very difficult, almost impossible, to print on the surface of wires and cables whose surface insulation layer is fluoroplastics. However, some wire and cable users need to have printed marks on the surface of the wire and cable during installation and use, so as to facilitate installation and use. Although my country has no requirements for printing on fluoroplastic wires and cables, some exported products, especially products exported to the European Community, especially VDE-certified products, require printing on the surface of wires and cables. [0003] Some foreign companies currently use...
