Automatic painting production line capable of recycling excess paint

Abstract

The invention discloses an automatic painting production line capable of recycling an excess paint. The production line comprises a closed annular main conveying chain, wherein the main conveying chain is dynamically connected with a main chain driving device; a rotatable workpiece hanging and holding device is arranged on the main conveying chain; and a paint dipping device, an excess paint recycling device and a drying chamber are arranged along the running direction of the main conveying chain in turn. When a workpiece is hung on the rotatable workpiece hanging and holding device, the workpiece passes through the paint dipping device, the excess paint recycling device and the drying chamber in turn along with the movement of the main conveying chain, wherein the workpiece is automatically dipped into a paint in the paint dipping device; the paint on the workpiece is automatically thrown off and the excess paint is automatically recycled in the excess paint recycling device; and finally, the workpiece is dried in the drying chamber. The whole process is automatically completed without an operator; and the recycled excess paint flows back into the paint dipping device for recycling.

Description

technical field [0001] The invention relates to the technical field of workpiece painting, in particular to an automatic painting assembly line with the function of recovering residual paint. Background technique [0002] At present, the painting of many furniture and wood products (water-based paint or nitro paint and other paints) is carried out by manual spraying or other methods. The labor intensity of the workers is high, and the automatic production line cannot be formed, and the production efficiency is low; the utilization rate of the paint is low. Only reach 30% to 35%. The excess paint is wasted in vain, and the residue paint is discharged into nature, polluting the environment, and does not meet the requirements of environmental protection; in the process of painting, the substances volatilized from the paint into the air seriously damage human health; the paint film on the surface of the workpiece sprayed manually Uneven thickness, poor surface leveling effect. ...
