Abstract

The invention provides an air door of a dust cleaner of a plasma cutter with simple structure and low cost, comprising an air tube. A fixed gate plate with fixed air holes is connected with one end of the air tube; the end face of a moving gate plate with moving air holes is contacted with the end face of the fixed gate plate, and the moving gate plate is connected with a transmission mechanism which drives the moving plate to move in the plane at which the moving gage plate is contacted with the fixed gate plate; and when the moving gate plate moves, the moving air holes can be axially overlapped with or staggered from the fixed air holes. The air door drives the moving gate plate to move through the transmission mechanism to cause the moving air holes and the fixed air holes to be axially overlapped with or staggered from one another. When the moving air holes and the fixed air holes are overlapped with one another, the air tube forms a passage, i.e. the air door makes an exhaust fan communicated with a cutting area. When the moving air holes and the fixed air holes are staggered from one another, the air tube forms a disconnection, i.e. the air door makes an exhaust fan separated from a cutting area.

Description

technical field [0001] The invention relates to a damper for a dust removal device of a plasma cutting machine. technical background [0002] Plasma cutting machines have been widely used in various fields of industrial production. When people use plasma cutting machines to cut steel plates and stainless steel, a large amount of smoke, dust and dazzling arc light will be generated. These smoke and dust will affect the production site and machine tool body. Pollution poses a threat to the health of operators and affects normal production and life. People have adopted dedusting device for this reason, and the exhaust fan is directly connected with the cutting zone of plasma cutting machine. But because the cutting area is long, the space in the cutting area is very large, and the effect of drafting is not ideal. So people divide the cutting area into isolated small partitions, and each partition is connected with the exhaust fan. This requires that when the cutting torch of...
