Description

Technical Field

[0001] The utility model relates to the field of electrostatic spraying machines, in particular to a curing furnace for spraying. Background Art

[0002] Curing refers to the production process of heating parts, curing resin and drying in the electronics industry and other industries to enhance the stress of material bonding. The container for curing is the curing furnace, which is suitable for the production process of heating parts, curing resin and drying in the electronics industry and other industries. After the workpiece is sprayed, it enters the curing furnace for high-temperature baking and curing;

[0003] When the workpiece is first baked at high temperature in the curing furnace, some paint particles will fly into the circulating air as the air flows. Due to the high temperature and the flow of air, these paint particles will adhere to the inside of the furnace, making it difficult to clean them. In addition, if paint particles of different colors fly to other color positions of the workpiece with the flow of air, it will affect the quality of the finished workpiece to a certain extent.

At the same time, the gear 45 and the rack 46 at the front end of the electrostatic ridge 44 are driven to drive all the other electrostatic ridges 44 to perform synchronous action, and then the four groups of electrostatic ridges 44 are turned over 120 degrees, and then the side of the electrostatic ridge 44 adsorbed with paint particles is moved to between the side plate 41 and the sealing plate 42 for cleaning.

[0031] In this embodiment: the cleaning mechanism 3 includes a sliding rod 33 slidably connected to the inside of the filter box 21, a scraper 34 that cooperates with the trapezoidal opening of the side plate 41 is fixed to the front end of the sliding rod 33, and the rear end of the sliding rod 33 is fixed to the front end of the sliding frame 32.
