Description

Liquid coating device and method

Technical Field

The invention relates to a coating construction device for the surface of an object, in particular to a liquid coating device and a liquid coating method.

Background

The wall surface coating work is an important link in building decoration, and influences the problems of the wall surface in aspects of beautiful appearance, water resistance, service life and the like. Especially, interior decoration can improve people's quality of life and happiness index, through a set of construction scheme and design scheme that certain design theory and pleasing to the eye rule formed, and wall coating work is an important work in the interior decoration process, and common coating liquid is coating, paint or waterproof paint.

Taking paint as an example, the decoration process in the prior art needs to paint the wall surface, and the wall surface is painted through the rolling brush generally, but in the process of painting the wall surface through the rolling brush, the paint on the rolling brush cannot be continuously supplied, so that the rolling brush needs to be frequently retracted to dip in the paint, the rolling brush needs to be used for dipping in the paint again after brushing one piece, the time and the labor are wasted, the working strength of staff is greatly improved, the paint is easy to splash and drop in the paint dipping process, and the waste and the pollution to the ground are caused. The thickness of the liquid brushed at the initial section of the rolling brush rolling is larger than that brushed at the tail end in a manner of dipping and adsorbing the liquid, a little corrugated boundary line is easily left at the moment, the attractive appearance is reduced, if the slight difference of the non-uniformity is to be eliminated, the thickness of the liquid is required to be kept uniform through repeated brushing for a plurality of times, and thus the time and the physical strength of workers are wasted, and a plurality of defects exist in back and forth dipping.

However, in the process of brushing paint, a constructor usually holds a paint brushing roller to brush paint, and when the paint is painted on an indoor ceiling or is higher than a human body touchable range, a worker can finish high-altitude painting by means of a ladder, an outdoor hanging basket or a hanging rope, and the worker is required to continuously transfer a charging basket, frequently bend down to put the roller into the charging basket to dip in the glue coating material, and then lift the roller onto a wall. The construction method has the advantages of high labor intensity, time and labor waste, low efficiency, easy coating of workers and extremely unsafe.

The spraying equipment on the market has the advantage of fast speed, but it need blow to the plane that waits to scribble after to the liquid atomizing, and the particle of spraying can fall in unspecified place, including on the body of the operator, hardly wash, and the operator still has inhaled danger, therefore need carry out the coverage protection when spraying, then need extra spending time and money, in some narrow and small spaces, it can be more inconvenient, still need manual work further processing afterwards. In order to prevent cross color, some accessories need to be cleaned and replaced after each working, and the accessories have non-universality, so that the maintenance cost is high, the maintenance time is long, and the skill requirements on workers are relatively high. The spraying equipment is often bigger, and is inconvenient to carry to need the circular telegram, in case meet the outdoor operation of far suburb, the power supply becomes an inconvenient factor, and wall painting effect also can have the difference because of personnel's technical level. The equipment has high purchase cost, is difficult to popularize in small occasions, has more parts and components, has high failure rate and high maintenance cost.

Although the spraying apparatus has the above-mentioned advantages and disadvantages, and the manual coating operation has the advantages and disadvantages, in the case of a relatively important application, painting is the most basic finishing step, and in order to achieve a high coating quality, a worker is required to grasp the quality, so that there is a need in the art for a liquid coating apparatus that can achieve both coating speed and quality.
