When the welding machine is used, in the welding process, the water pump 5and the smoke exhaust fan 7 are started, so that the water mist spray head 3 sprays water mist towards the periphery of the welding workbench 12, the air humidity is increased, a water curtain is formed, welding smoke above the welding workbench 12 is prevented from escaping towards the periphery, and the sedimentation of part of the escaping welding smoke is accelerated. The smoke exhaust fan 7 sucks a large amount of smoke generated above the welding workbench 12 into the box body 9 through the smoke exhaust pipeline 6, filters the smoke through the filter element 15 and discharges the smoke, and simultaneously sucks away part of water mist dissipated above the welding workbench 12, so that the adverse effect on the welding process due to overhigh humidity above the welding workbench 12 is prevented.
When the smoke exhaust fan 7 works for a certain period of time, the filter element 15 needs to be cleaned, the dust removal motor 8 is started at this time, the dust removal motor 8 drives the ejector rod 36 to rotate, the ejector rod 36 pushes the pushing piece 35 to move, the pushing piece 35 presses the button 33 to stop the smoke exhaust fan 7, meanwhile, the clutch components are communicated, the power of the dust removal motor 8 is transmitted to the transmission component to drive the filter element component to reciprocate left and right, and welding fume adsorbed on the filter element 15 falls off. Meanwhile, the poking assembly is driven by the pushing piece 35 to push the horizontal baffle 37 to turn downwards, so that the falling welding fume falls into the dust storage cavity 904, and the fume is prevented from being sucked up again when the subsequent fume exhaust fan 7 works.
The push pieces 35 on two sides are pushed once respectively when the push rod 36 rotates for each circle, so that the two smoke exhaust fans 7 work alternately, when one smoke exhaust fan 7 stops working, the other smoke exhaust fan 7 keeps working, and thus the phenomenon that welding smoke cannot be sucked due to the fact that the two smoke exhaust fans 7 are stopped is avoided, and the welding process can be continuously carried out for a long time.
The invention can uniformly humidify the periphery of the welding workbench 12, effectively promote the sedimentation of welding smoke dissipated from the periphery to the upper side of the welding workbench 12, and avoid the adverse effect on the welding process caused by the overhigh humidity above the welding workbench 12.
