Abstract

The invention discloses a spraying machine for architectural decoration with adjustable spraying range, which includes a spraying device, wherein the spraying device is arranged on a three-axis mobile platform, and the three-axis mobile platform is also provided with a follow-up spraying device capable of moving forward and backward. and a storage tank that moves left and right, the spraying device can spray negatively charged atomized paint, and can adjust the spraying range of the atomized paint. Compared with the prior art, the spraying machine for building decoration and decoration forms a smoother and more uniform coating on the surface of the painted workpiece, and the adhesion of the paint film is higher, and the spraying range of the paint can be adjusted more accurately.

Description

technical field [0001] The invention relates to the technical field of building decoration equipment, in particular to a spraying machine for building decoration with adjustable spraying range. Background technique [0002] Decorative spraying is a coating method in which spray guns or atomizers are dispersed into uniform and fine mist droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and so on. The technology and environment are very strict when spraying, and a little carelessness will cause the coating effect to fail to achieve the desired effect.

Problems solved by technology

The technology and environment are very strict when spraying, and a little carelessness will cause the coating effect to fail to achieve the desired effect

[0003] Most of the existing spraying equipment is hand-held, and the position and duration of spraying are manually grasped during spraying, and the position of the nozzle needs to be moved in multiple directions during spraying, which is likely to cause uneven spraying, and the paint is easy to scatter and rebound during spraying. Poor environment, easy to cause pollution, and waste paint

[0004] The existing electrostatic spraying device can better control the splashing and rebounding of the paint. However, when the paint with conductivity and in a non-conductive state is in the equipment, the corona current leakage at the paint charging point and the current caused by the electric spark discharge will pass through. Flowing paint and the resulting inductive separation can change one or more of the fluidic properties of the paint, such as viscosity, resistivity, and surface tension, and thus can change the charge-to-mass ratio of the spray result. Changes in the charge-to-mass ratio affect spray build-up and can hinder Spray quality index

Moreover, unless the equipment is highly insulated, voltages above 10KV can break down over a distance of approximately 6mm, thereby leaking to the chassis and causing an electric shock risk

[0005] In addition, in the existing air spraying device, the spraying of the paint is guided by the air flow to prevent the paint from scattering. However, since the guided air is supplied in almost the same direction as the sprayed paint, it cannot solve the problem of paint spraying very well. The problem of dispersion, in addition, the paint has the problem of solvent volatilization too fast in the air flow, which tends to coagulate and cause small particles to be sprayed

[0006] In addition, most of the existing spraying devices control the spraying range by adjusting the pressure or flow rate, and cannot accurately control the spraying range at a certain flow rate.
