Description

Laser engraving cutting machine

Technical Field

The utility model relates to the technical field of laser engraving cutting machines, in particular to a laser engraving cutting machine.

Background

Laser engraving cutting machine: the laser has high coherence, high intensity and high directivity, and the laser is transmitted by the reflecting mirror after being generated by the laser and irradiates the processed object through the collecting mirror, so that the temperature of the processed object (surface) is rapidly increased due to strong heat energy, the point is rapidly melted or vaporized due to high temperature, and the processing purpose is achieved by matching with the running track of the laser head. Although laser light is light, it is significantly different from ordinary light in that laser light depends on spontaneous emission only for an initial extremely short period of time, and the process thereafter is entirely determined by the laser radiation, so that laser light has a very pure color, almost no divergent directivity, and extremely high luminous intensity. A typical engraving machine may engrave the following materials: wood products, organic glass, metal plates, glass, stone, crystal, colli-able, paper, double-color plates, alumina, leather, resin, and plastic-sprayed metal. Ordinary mechanical engraving cannot engrave dots of varying thickness in an economical manner and thus does not have a gray scale representation. The laser engraving machine is used for realizing engraving in a dotting mode and has the natural advantage in gray scale expression. The gray scale expression form is adopted as much as possible in the engraving design, so that the coloring process is reduced and the cost is saved; on the other hand, the method enriches the expression means of engraving and increases the level of the graph.

The existing laser engraving cutting machine can generate heat in the laser engraving cutting machine when the laser engraving cutting machine is used in hot seasons, heat dissipation is generally achieved through the installation of the heat dissipation fan and the opening holes, in addition, because some smoke and dust smoke can be generated in the use process of the laser engraving cutting machine, the laser engraving cutting machine is generally directly extracted and discharged through the fan, the laser engraving cutting machine is not filtered and is discharged into ambient air, the human body is not harmed, in addition, the laser engraving cutting machine cannot be well dissipated in hot seasons through the opening holes and the heat dissipation mode of the heat dissipation fan, and if the heat dissipation fan is additionally arranged, the cost and the resource use are increased.
