Abstract

A centrifugal basket of a Dacromet dip-coating machine comprises a basket body which includes a basket bottom and a basket wall. The lower end of the basket wall is connected with the basket bottom. A basket opening is defined by the upper end of the basket wall. The basket wall is provided with a plurality of liquid drain holes. The centrifugal basket of the Dacromet dip-coating machine is characterized in that the lower portion of the basket wall is in a big end up round platform shape. The lower portion of the basket wall is equivalently to an annular slope, accordingly, when the centrifugal basket rotates, workpieces at the basket bottom move upwards along the annular slope arranged at the lower portion of the basket wall under the centrifugal force, the workpieces are spread on the basket wall of the centrifugal basket, thereby enlarging the actual centrifugal area of the workpieces, enabling more workpieces to be centrifuged fully and the thickness of the coating surface to be even, and enhancing centrifugal effect. When the workpieces move upwards to a certain height, the workpieces fall on the basket bottom again under the action of gravity, accordingly, the workpieces in the centrifugal basket turn over fully under both the centrifugal force and the action of gravity. The positions of the workpieces in the centrifugal basket change continuously, thereby effectively resolving problems that the coating solution stacks and sticks to each other to form a block.
