A kind of equipment and spraying method for applying nano-spraying technology to spray-coat piano shell

Abstract

An equipment and a spraying method for spraying a piano shell using nano-spraying technology, including a transmission mechanism and a spraying mechanism, the transmission mechanism includes front and rear push structures and a middle transmission frame, the push structure includes a base, There is a chute on the top of the chute, and a push-pull device is installed on the left and right sides of the chute. The transmission frame includes a transmission chain, and a plurality of brackets are installed on the transmission chain. The brackets are directly opposite to the chute. , The front and rear movement mechanism is equipped with an up and down movement mechanism, and double nozzles are installed on the up and down movement mechanism. The invention provides a device and a spraying method for spraying a piano shell using nano-spraying technology. By setting a transmission mechanism and a spraying mechanism, the spraying operation is not only automated, but also the spraying effect is improved to ensure the quality of the piano shell.

Description

technical field [0001] The invention belongs to the field of piano casing spraying, in particular to a device and a spraying method for spraying a piano casing using nanometer spraying technology. Background technique [0002] The traditional method of spraying coatings containing metal powder (usually aluminum powder and copper-zinc powder) is generally difficult to obtain a mirror-like metal surface, because the particle size of the metal powder is too large, and it is difficult to form a continuous and smooth metal layer in the coating film , so it often presents a matte, semi-matte or shimmering metallic effect. [0003] Electroplating is to connect the positive and negative poles of the DC power supply to the anode and cathode of the plating tank. The anions in the electroplating solution lose electrons at the anode to undergo an oxidation reaction, and the cations gain electrons at the cathode to undergo a reduction reaction. The anode will enter the solution with the ...

AI Technical Summary

Problems solved by technology

[0004] The conventional spraying of wooden piano shells generally uses manual or machine to directly spray paint on the soundboard. This spraying method has the following defects: 1), the coating film is uneven, and the color difference is serious, which affects the quality of the piano sound quality; 2), The spraying speed is slow and the processing efficiency is low; 3), the paint consumption is large, and the production cost of the sound board is high

[0005] In addition, the traditional wooden piano shell needs to be sprayed with primer, intermediate layer, top coat, etc., and it needs to be dried in the front and rear spraying processes, so it is necessary to manually hang the dried wooden piano shell on the conveyor chain through the device for transmission In the next spraying process, the labor intensity is very high and the operation efficiency is low
