Abstract

The invention discloses a shaftless rotary coating device. Powder in a coating cavity is uniformly suspended. The coating device comprises a coating barrel with an opening in the top, an air inlet is formed in the bottom wall of the coating barrel, a fluidization plate is horizontally arranged in the coating barrel, and an inner cavity of the coating barrel is divided into a coating cavity and an air inlet cavity by the fluidization plate; the coating cavity is positioned above the air inlet cavity; an annular piece capable of rotating around the axis L of the annular piece is arranged in the coating cavity; the lower part of the annular part is connected with a stirring part; and the driving mechanism is used for driving the annular piece to rotate. And therefore, the workpiece is uniformly dip-coated, and the surface quality is good. And meanwhile, the device has the advantages of high reliability, dust resistance, light weight and the like.

Description

technical field [0001] The invention belongs to the technical field of surface coating, in particular to a shaftless rotary coating device. Background technique [0002] The surface coating technology is to place the workpiece in the fluidized powder, and then the workpiece is powder-coated. In the actual operation process, the powder is fluidized by the airflow fed into the coating barrel, and the air pressure decreases when the airflow enters the tank. Under the action of gravity, it is easy to cause uneven distribution of the fluidized powder in the coating barrel, which in turn leads to unevenness of the workpiece. Dip coating, poor surface quality. [0003] In order to solve the above technical problems, the patent document with the application number of 202110895855.5 discloses a small pneumatic surface coating equipment. The vibrating device provides vibration for the coating barrel while the lifting device drives the parts moved down in the coating barrel. surface ...
