Description

Power-up electrostatic rotating cup sprays agriculture machine cockpit and its operating method automatically in a kind of
Technical field
The invention belongs to application techniques field, it is related to power-up electrostatic rotating cup in one kind and sprays agriculture machine cockpit automatically, it is special It is not to be related to power-up electrostatic rotating cup in one kind spraying agriculture machine cockpit and its operating method automatically.
Background technology
Currently, the three wastes（Waste water,waste gas and industrial residue）Worldwide problem, wherein solvent based coating are had become to the pollution of environment Application the pollution of air is particularly acute, various countries are to volatile organic matter in application（Hereinafter referred to as VOCs）, limitation it is more next Stringenter, discharge capacity Con trolling index constantly declines, to advance the birth of efficiently spray tool and new type environment friendly coating, electrostatic rotating Cup is with its high rotating speed, the high atomization of high voltage generation, high painting rate, high paint film quality by numerous enterprises using application techniques It is widely used；And water paint, with water as solvent, discharge capacity is low, meets the requirement of increasingly stringent environmental regulation.
Currently, China is gradually increased environmental improvement dynamics, China's automobile industry early begins to promote and apply high-temperature baking water Property paint, has become the entry criteria of newly-built painting dressing automobiles project at present.And the general industries such as agricultural machinery（ACE）Not with automobile industry Together, the features such as small, wide in variety, manufacturing technology and differences in materials are big due to its yield, agriculture machine cockpit is mostly manually to make at present Low temperature two-component solvent paint is sprayed with air gun, utilization efficiency of coatings is low；Many enterprises also use artificial Puttying polishing operation, Spray painting and Puttying operation are carried out with intermittent chamber body or without chamber body, Puttying polishing area is larger, dust and VOCs discharge capacitys Greatly, manual work environment is poor, and labor intensity is big, and paint line process equipment and automatization level are relatively low, faces increasingly strict ring Conformal gesture, application techniques transition and upgrade are very urgent.
