A system for recovering paint and cleaning in a painting machine having a conveying band for conveying panels to be painted includes a paint recovery unit for paint recovery having a reverse roller in contact with the conveying band, recovering paint sprayed on the conveying band, and a doctor blade scraping the reverse roller to recover paint for successive channelling to a tank; a cleaning unit having a cleaning roller, a drying blade, and an idle roller; a paint recovery unit provided as an independent unit; and a cleaning unit for the conveying band provided as an independent unit.

An overspray spray capture structure integrated into a paint spray operation integrates at least one reception surface for receiving an overspray of the spray coating operation. The overspray is communicated through a merging location established between the receiving surfaces and adapted to being removed or recycled. The at least one reception surface further includes first and second oriented reception surfaces not limited to a pair of horizontal and vertical closed loop belt curtains which are traversable supported about a pair of spaced apart rotating shafts. The first and second reception surfaces can include traversing paper rolls for capturing the overspray therebetween at the merging location. Other variants include water curtain or vacuum removal assist assemblies for removing the overspray prior to it setting.

A spraying device comprises: a conveyer comprising a mesh crawler belt configured to carry an object to be sprayed; a baking chamber for heating the object to be sprayed; a spraying chamber having at least one atomizing nozzle disposed within the spraying chamber, the atomizing nozzle being configured to uniformly spray a coating solution on a surface of the object to be sprayed; a cleaning chamber for cleaning the mesh crawler belt and recycling the coating solution carried by the mesh crawler belt; and a solution storage apparatus for storing the coating solution that the spraying chamber needs for spraying; wherein the mesh crawler belt passes successively through the baking chamber, the spraying chamber and the cleaning chamber. The device of the present invention can ensure uniformity of the thickness of a coating layer on the magnet. In addition, the device can improve spraying efficiency and save raw material.

A method for forming a thin film having durability at a low cost is provided. A film formation apparatus 1 is used in the film formation method. The apparatus 1 comprises a vacuum container 11 in which a substrate 100 is placed at a lower part, a vacuum pump 15 for exhaust inside the container 11, a storage container 23 for storing a coating agent 21 provided outside the container 11, and a nozzle having an ejection part 19 capable of ejecting the coating agent 21 at its one end. A solution including two or more kinds of materials including a first material (S1) and a second material (S2) having a higher vapor pressure (P2) than a vapor pressure (P1) of the Si is used as the coating agent 21. The coating agent 21 is ejected to the substrate in an atmosphere with a pressure higher than P1 and lower than P2.
