Description

Surface treatment equipment

The present invention relates to a surface treatment equipment, in particular to a surface treatment equipment 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 that coats the surface of workpieces (such as screws) with anti-rust or dyeing paint, mainly puts the workpiece into a barrel, and then immerses the barrel in a coating relative to each other. In the paint tank of the coating device, the paint in the paint tank is allowed to adhere 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 easily remains in the surface gaps of the workpiece, such as grooves or holes on the surface of the workpiece. If the paint-coated workpiece is directly sent to the drying device for drying, it is easy to cause excess paint. The paint blocks the grooves or holes on the metal surface, or causes uneven coating of paint on the surface of the grooves or holes of the workpiece, affecting the quality and output of the surface treatment of the workpiece.

In order to improve the problem of uneven paint coating, the existing method is to reduce the number of workpieces sent to the coating device for paint coating each time to avoid excessive paint remaining in the paint bucket when the paint bucket is taken out. 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 barrel conveying path and the workpiece conveying path of the drying device are arranged in a straight line relative to each other, and a pouring device provided at the discharge end of the barrel conveying path is used to transfer the material into the barrel. The paint-coated workpieces are directly dumped into the feeding position of the workpiece conveying path of the drying device. Therefore, the overall length of the existing surface treatment equipment is very long, making it difficult to install it in a factory with limited length.

In order to avoid the problem that when the workpiece is surface treated, the paint is easily coated unevenly and remains in the gaps of the workpiece, as well as the problem of low output in each process, the main purpose of the present invention is to provide a surface treatment equipment. Before putting the paint-coated workpiece into the drying device, it is first poured into a centrifugal device to shake off the excess paint, and then poured into the drying device for drying to improve the quality of the surface treatment of the workpiece.

In order to achieve the above objectives, the surface treatment equipment of the present invention includes a barrel conveying unit, a drying device, a material pouring device, and a centrifugal unit, wherein: The barrel conveying unit can transport a barrel between the inlet end and the discharge end of a barrel conveying path; The drying device is adjacent to and juxtaposed with the barrel conveying unit.
