The importance of the exhaust system of the laser cutting machine
During the cutting process of the laser cutting machine, due to high temperature ablation, more smoke and dust will be generated, which will pollute some precision parts of the equipment. At the same time, the smoke and dust will also have an adverse effect on the health of the operators. If the cutting fume is not treated, it will seriously affect the service life and cutting performance of the laser cutting machine, and at the same time affect the industry popularity and development prospects of the laser cutting machine.
Generally, the exhaust device of the laser cutting machine is designed as an overall exhaust structure, with a large cavity. In order to meet environmental protection requirements, a high-power dust collector is required, which covers a large area. The pipeline installation is complicated, and it is easy to produce leaks and air leakage, resulting in poor ventilation effect. In actual work, the generated smoke and dust cannot be exhausted in time, which will affect the user's working environment.
One solution is to use partitions to divide the lower part of the laser cutting machine's worktable into a number of longitudinally arranged small rooms with equal geometric dimensions and the main suction at the front The main suction duct is connected to the dust collector; each compartment is equipped with a valve between the main suction duct, and the machine-controlled valve controls the cylinder through the intake pipe and the outlet pipe; the compartment is equipped with a hopper, and the two ends are welded with end plates to seal. There are several ventilation holes in the lower part of both sides of the bucket.
The ventilation process of the system is controlled through the opening and closing of the valve. This method saves land and improves the ventilation effect.
Another solution is the device including the main body, the main box and the control cabinet. The exhaust hood is set to absorb all the smoke and dust generated by the laser cutting machine when it is working, which can ensure the line of sight of the laser cutting machine. It is clear and improves work efficiency. The exhaust hood can also ensure that residues will not splash around during work, protect the safety of operators, improve a layer of protection, and improve the popularity and applicability of the device.
Although the ventilation system is not the most important consideration when choosing a laser cutting machine, an efficient ventilation system is an important condition to ensure normal production and must not be ignored.
