Description

Surface treatment equipment

The present invention relates to a surface treatment device, in particular to a surface treatment device that is provided with a centrifugal unit between a coating device and a drying device, and uses the centrifugal unit to throw off excess paint on the surface of a workpiece.

Existing surface treatment equipment, such as surface treatment equipment for coating the surface of workpieces (such as screws) with anti-rust or dyeing paints, mainly puts the workpiece into a bucket, and then relatively immerses the bucket into a paint. The paint in the paint tank is attached to the surface of the workpiece, and finally the paint-coated workpiece is sent to a drying device for drying.

However, after the workpiece is coated with paint, the paint is likely to remain in the surface gaps of the workpiece, such as grooves or holes on the surface of the workpiece. If the painted workpiece is directly sent to the drying device for drying, it is easy to make excess The paint is blocked in the grooves or holes on the metal surface, or the paint coating on the surface of the grooves or holes of the workpiece is uneven, which affects the quality and output of the surface treatment of the workpiece.

In order to improve the problem of uneven coating of paint, the existing method is to reduce the number of workpieces that are sent to the coating device for paint coating each time, so as to avoid excessive paint remaining in the paint bucket when the paint bucket is taken out from the paint bucket. between the workpieces in the barrel, thereby reducing the output of each process, which is not ideal.

Furthermore, the existing surface treatment equipment is based on the continuity of automated operations. The conveying path of the bucket and the conveying path of the workpiece of the drying device are arranged in a straight line opposite to each other. The painted workpieces are poured directly into the drying device The feeding position of the workpiece conveying path, therefore, the overall length of the existing surface treatment equipment is very long, and it is difficult to install it in a workshop with limited length.
