[0002] Ventilation ducts are hollow pipes used for ventilation, mostly in round or square shapes. Plates, profiles and other main finished materials used for the production and installation of ventilation ducts. Ventilation ducts generally include purification system return air ducts, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, mining rubberized cloth air ducts and fire smoke ventilation ducts. During the processing of ventilation ducts, it is usually necessary to use a laser cutting machine to cut the plate according to specific dimensions. When using existing laser cutting, it is generally necessary to manually move the plate to the position of the cutting head. This processing method results in poor cutting continuity and cutting accuracy, so that the entire cutting process is relatively cumbersome, which is not conducive to the rhythm of modern production. To this end, we provide a laser cutting machine for ventilation duct processing to solve the above problems. Utility Model Content

This pressing method is suitable for plates to be cut of different thicknesses. A support plate 13 is provided on the inner cavity of the base 1 on the side of the cutting head 4 away from the active roller 5.

The motor 9 serves as a power source for driving the active roller 5 to rotate, and the output speed of the motor 9 is reduced by the reducer 10, thereby realizing the driving of the active roller 5.

[0015] Specifically, the inner cavity of the base 1 is rotatably provided with a plurality of rollers 11, and the plurality of rollers 11 are at the same height as the active roller 5. The design purpose is to support the plate before it enters the active roller 5, and to change the original sliding friction into rolling friction, thereby reducing the loss of the plate and increasing the conveying efficiency.
