Description

Air door device for dust removal system of cutting machine

Technical Field

The utility model belongs to the technical field of the cutting, more specifically say, relate to an air door device for cutting machine dust pelletizing system.

Background

The cutting machine includes a laser cutting machine, a plasma cutting machine, a flame cutting machine, and the like. The working process of the cutting machine is that the cutting tool which is randomly worn cuts an object when the cutting machine moves along with a machine tool. The laser cutting machine has the fastest efficiency, the highest cutting precision and generally smaller cutting thickness. The plasma cutting machine has fast cutting speed and certain slope of the cut surface. The flame cutting machine is used for carbon steel materials with larger thickness.

Taking a laser cutting machine as an example, the laser cutting principle mainly refers to cutting a cut material by a cutting mode with melting and a cutting mode with oxidation melting. During the cutting of the material, the cutting machines release a considerable amount of fumes containing components mainly consisting of metallic dust and board fumes, respectively. In addition, if the laser cutting machine employs an oxygen fusion cutting mechanism, the laser cutting machine releases a large amount of smoke and dust during cutting of a material, and the smoke and dust mainly contain metal oxide particles of metals such as iron oxide and aluminum oxide. Meanwhile, in order to meet the requirements of the cutting process of the laser cutting machine, the laser cutting machine needs to spray lubricating oil on the table top of the worktable before cutting the metal material, and the purpose of spraying the lubricating oil is to improve the smoothness of the table top. In addition, when a polyethylene protective film is adhered to the working table top of the laser cutting machine, smoke dust released by the laser cutting machine in the process of cutting materials mainly contains the following components, namely aliphatic compounds, alkene compounds and other compounds, and smoke dust containing the components has a great peculiar smell and can cause serious damage to human bodies.

Similarly, the plasma cutting machine and the flame cutting machine inevitably generate smoke and dust in the cutting process, so the cutting machine is generally provided with a dust removal system. The existing dust removal system adopts a mode that an air cylinder ejects an air door or turns upwards in the tube in the vertical direction, so that some problems exist. Firstly, the air inlet is generally in the form of a small grid and small in area, and the air inlet is upwards ejected from the inside of an air duct to realize opening and closing, so that the wind resistance can be enhanced; moreover, the air door is opened and closed in a vertical rotating mode from the inside of the air duct, and the air outlet has a shunting condition, so that the wind resistance is high, the wind power and the wind pressure are not fully exerted, the dust removal effect is not ideal, and the waste of the power of the fan is caused.

For example, chinese patent application No. 201120548438.5, published as 2012 and 9/19, discloses a partition dust removing device for a large format laser cutting machine. This patent dust collector includes two parallel machine tool bases, spanes in two parallel machine tool base tops and can follow the gliding crossbeam of linear guide and cantilever beam, cantilever beam one end can slide along crossbeam length direction on the crossbeam, and the cantilever beam other end is equipped with the laser cutting head that can relative cantilever beam free motion, is equipped with dust removal structure between the two parallel machine tool bases, dust removal structure is equipped with the dust absorption mouth including using the perpendicular divided a set of dust absorption wind channel of baffle, every dust absorption wind channel one side, and every dust absorption mouth correspondence is equipped with the air door. However, the air door of the dust collection air duct is of a small grid structure, so that the area is small, the air resistance is large, and the dust collection effect is poor.

For another example, chinese patent application No. 201920444064.9, published as 2020, 1/17, discloses a laser cutting machine damper device. The patent air duct is arranged on one side of the cutting chamber, and is provided with openings which are grid-shaped openings at equal intervals; the air duct is also provided with an air door structure, the air door structure comprises a pressing plate and a sliding door, the pressing plate is arranged on two sides of the opening, the pressing plate is provided with a sliding groove, and the sliding door is arranged in the sliding groove and can slide in the sliding groove; the sliding door is provided with grid-shaped air ports at equal intervals corresponding to the opening, and the air ports can completely shield or expose gaps among grids of the opening. However, the air door is still a grid-type opening, and the air outlet has a shunting condition, so that the air resistance is large and the dust removal effect is poor.

Therefore, in order to improve the dust removing effect, the design of the damper needs to be improved.
