Technical Field

The invention relates to the technical field of building construction, in particular to a glue scraping device and a glue scraping method for assisting wallpaper mounting.

Background

Wallpaper, also called wallpaper, is an interior decoration material for pasting a wall surface, and is more and more popular to be pasted with wallpaper based on consideration of aesthetic property in the interior decoration process. In the prior art, wall paper and a wall are usually bonded by an adhesive such as glutinous rice glue, in order to ensure the flatness of the wall paper, a scraper blade is usually used for leveling the adhesive after the adhesive is coated on the wall, and then the wall paper is pasted; however, the scraper blade that uses at present usually is the broach formula, can peel off a large amount of adhesives wall when the scraper carries out the flattening to the adhesive promptly usually, after wall paper pastes the dress and accomplishes, the temperature of the air of direct contact with the wall paper, humidity alternate change, the seam crossing of wall paper often can take place to stick up the limit phenomenon because of the adhesive is not enough, though this phenomenon accessible secondary pastes dress and carries out the flattening, but, the time node that sticks up the limit phenomenon and takes place is usually after the fitment is accomplished, the householder goes to look for professional fitment team to carry out the flattening obviously not calculated this moment, based on the consideration of economic nature, the householder can open the flattening repair work by oneself, because many factors such as experience is not enough, the wall paper seam that the householder was done oneself can appear phenomenons such as bubble, fold, seriously influence the aesthetic property and the harmony of wall paper.

Chinese patent application No. CN201711445948.8 discloses a wallpaper mounting process, which comprises the following steps:

A. mounting wallpaper on a wallpaper roller, and putting filler;

B. aligning a filler nozzle below the wallpaper roller, and calibrating the verticality of the pressing roller and the induction roller strip;

C. fixing the starting end of the wallpaper, starting a wallpaper roller of the wallpaper pasting device to rotate, spraying filler to a wall body below the wallpaper by a filler nozzle, pressing the wallpaper into the wall body by a pressing roller above the wallpaper moving downwards, and inducing the surface stress of the wallpaper by a roller strip;

D. if the induction roller strip induces the surface of the wallpaper to be stressed little, the wallpaper roller moves upwards, the filler nozzle sprays another hard filler, and the step C is repeated; until the work is finished, the wallpaper is cut off.
