Abstract

The invention relates to the technical field of material coating equipment, and provides a spraying device which comprises a direct-acting driving mechanism, a liquid drop spraying adjusting device, a runner plate and a spraying plate. And the liquid drop spraying adjusting device is connected with the direct-acting driving mechanism. And the runner plate is supported and connected between the liquid drop spraying adjusting device and the spraying plate, so that a fluid channel is formed between the liquid drop spraying adjusting device and the spraying plate. And spraying holes are formed in the spraying plate. The fluid channel is communicated with the spray hole. The direct-acting type driving mechanism can linearly jump and drive the liquid drop spraying adjusting device to move so as to adjust the distance between the liquid drop spraying adjusting device and the spraying hole. The spraying pressure of the coating can be changed by adjusting the distance between the liquid drop spraying adjusting device and the spraying holes in the spraying plate, and then the liquid drop spraying speed and the size of sprayed liquid drops are adjusted. According to the spraying device, a piezoelectric ceramic lever mechanism for torque transmission is replaced with a direct-acting driving mechanism which bounces in a linear reciprocating mode, the reliability is higher, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of material coating equipment, in particular to a spraying device. Background technique [0002] Spraying is a processing method in which the paint is dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. Traditional spraying devices include atomizing nozzles, and the paint sprayed by the atomizing nozzles is fan-shaped. When spraying multiple colors, it is usually necessary to mask the sprayed areas of the remaining colors, and the spraying efficiency is low. There are some spraying devices capable of spraying droplets in the prior art, and the spraying boundary is relatively clear. However, most of the existing spraying devices use a piezoelectric ceramic block lever mechanism as a droplet adjustment drive device to adjust the state of sprayed droplets. The piezoelectric ceramic lever mechanism is a torque transmission s...
