Embodiment Construction

[0014] 1. The smoke exhaust device of the present invention is made of 0.9-1.2MM iron plate. For the specific manufacturing method, please refer to Figure 1 to Figure 7 .

[0015] 2. Place the device on the laminate support 13 under the working surface 8 of the laser engraving (cutting) machine (see Figure eight ). The double bell mouth air suction nozzle 2 is modularized. After taking out the exhaust pipe 6, it is inserted into the bracket 12. The other end of the exhaust pipe 6 is connected to the centrifugal fan 7. A figure-eight movable cover 3 is placed above the suction nozzle to complete the smoke exhaust. System installation (the air nozzle cavity embedded filter 11 is optional).

[0016] 3. When the large-format workpiece 9 is processed, open the air door inserts 5 (A / B) on both sides of the bell mouth, and open the centrifugal fan 7 to work normally. During laser engraving, flue gas mainly concentrates on the workpiece 9 tops, and air inlet holes 13 around the w...

Abstract

The invention discloses a double-funnel type medium-pressure smoke discharging device for a laser engraving (cutting) machine, which comprises a double-funnel type fan cover with an air hole on the periphery, a dual-horn mouth air suction nozzle, a dual plugging air door, and a splayed movable cover plate. The lower end of the dual-horn mouth air suction nozzle which is positioned in the center of the whole fan cover is connected with an exhaust duct, and the other end of the exhaust duct is connected with a powerful exhaust fan. The powerful negative pressure generated by the fan is guided through the exhaust duct by the dual-horn mouth air suction nozzle; and strong negative pressure airflow is generated in the middle space of the double-funnel fan cover so as to extend towards the periphery to the edge of the fan cover, so that toxic and harmful flue gas generated during laser engraving (cutting) processing is rapidly and efficiently discharged. The double-funnel type medium-pressure smoke discharging device for the laser engraving (cutting) machine also has the advantage of convenient installation, use and maintenance.

Description

【Technical field】 [0001] The invention is a smoke exhaust device suitable for the field of laser engraving (cutting) machines. 【technical background】 [0002] The basic principle of the laser engraving (cutting) machine is to shape the workpiece placed on the worktable by burning with a high-energy laser beam. Accompanied by the laser processing process, a large amount of toxic and harmful fumes will be produced, which will pollute the environment and corrode the machine. The general composition of the laser machine smoke exhaust system is: the work surface (workpiece) - the smoke exhaust device inside the machine - the smoke exhaust pipe - the exhaust fan. In order to reduce the impact of fan vibration on the working accuracy, the fans are fixed away from the machine. It can be seen that the effect of the smoke exhaust system of a laser machine is mainly determined by whether the design of the smoke exhaust device inside the machine is reasonable. While ensuring efficient...
