Sealing device for laser cutting machines

Abstract

The invention relates to a sealing device for laser cutting machines, which is concretely used for sealing laser transmission in the laser cutting machines and belongs to the technical field of laser cutting equipment. The sealing device mainly comprises a back vertical plate, a red light seat, a total reflective mirror seat, a back sealing cover of a light exit cavity, the back vertical plate of a light gathering cavity, an inner-layer cover of the light gathering cavity, a laser generator, a base, an outer-layer cover, a front vertical plate of the light gathering cavity, a front sealing cover of the light exit cavity, a half reflective mirror seat, a front A cover of a beam expanding mirror, a front B cover of the beam expanding mirror, the beam expanding mirror, a pipe clamp head, a back A cover of the beam expanding mirror, a back B cover of the beam expanding mirror, a holophote seat and the front vertical plate. The sealing device disclosed by the invention is simple, compact and reasonable in structure, good in sealing effect, capable of effectively preventing light leakage, good in smoke and dust preventing effect, convenient for installation and adjustment and capable of bearing a certain high temperature.

Description

technical field [0001] The invention relates to a sealing device for a laser cutting machine, in particular it is used for sealing the laser transmission in the laser cutting machine, and belongs to the technical field of laser cutting equipment. Background technique [0002] Laser cutting machine uses laser as a processing method to process parts of metal and non-metal plates, and can process straight lines or curves of any shape on flat plates. This equipment is a high-efficiency and low-cost plate cutting equipment, widely used in textile machinery, machinery manufacturing, automobiles, instrument switches, home appliance manufacturing, elevator equipment manufacturing, food industry, decoration and advertising, etc. [0003] During the use of the laser cutting machine, the smoke, dust, or the smoke, dust, and chips in the surrounding environment will have an adverse effect on the normal use of the laser processing equipment. Light ones will increase optical path transmi...

AI Technical Summary

Problems solved by technology

[0003] During the use of the laser cutting machine, the smoke, dust, or the smoke, dust, and chips in the surrounding environment will have an adverse effect on the normal use of the laser processing equipment.

Light ones will increase optical path transmission loss, reduce laser cutting ability and efficiency, and severe ones will damage optical elements such as optical lenses, increase maintenance and repair costs, and cause equipment downtime losses; at the same time, light leakage will cause harm to human health
