Plasma nozzle structure

Abstract

The invention belongs to the technical field of nozzles, and particularly relates to a plasma nozzle structure for surface treatment of a gold and silver card color box. The plasma nozzle structure comprises a nozzle body, wherein a spraying channel is arranged in the nozzle body, and a hole channel communicated with the spraying channel is formed around an outlet of the spraying channel. Compared with the prior art, the improved plasma nozzle can completely eradicate generation of sparks, the conductivity of the coating is weakened within the range of 10 cm, no matter how long the gold and silver coating is, the nozzle of a plasma gun only needs to be reasonably erected, the treated gold and silver card coating is guaranteed to be positioned in the advancing direction, the contact conductor is out of the range of 10 cm, and the problems of electric conduction, spark generation and the like of a conventional plasma nozzle can be completely avoided.

Description

technical field [0001] The invention belongs to the technical field of nozzles, in particular to a plasma nozzle structure used for surface treatment of gold and silver card color boxes. Background technique [0002] Plasma surface treatment is applied in the field of pasting boxes. Its main function is to clean and activate the paper surface and improve adhesion. It has the advantages of low temperature, environmental protection, energy saving, and high efficiency. This surface treatment process before pasting has been popularized in this industry. [0003] Gold and silver card color boxes are currently widely used as cigarette boxes, wine boxes, food boxes, cosmetic boxes, toothpaste boxes, medicine boxes and gift boxes. However, when this layer of gold and silver coating is treated with a plasma treatment process, since the coating can conduct electricity, it is easy to generate sparks, interfere with the folder gluer, and even cause damage. If the operator touches the ...

AI Technical Summary

Problems solved by technology

These plasmas are actually charged, and the gold and silver card coatings are easy to conduct electricity. If the gold and silver card coating strips touch other conductors while processing, the "poor contact" method of this high-speed traveling method is of course prone to sparks

[0004] In order to solve the above problems, the usual practice in this field is to wrap the conductive parts within half a meter of the processing area with insulating materials such as flannelette, but because the folder-gluer platform except for the belt, many wallboards, fixtures, etc. are all conductors. , this method of wrapping insulating materials is time-consuming and laborious, and cannot completely eliminate potential safety hazards (such as loosening of the insulating layer, wear, etc.)
