Further, the handle is a steel pipe which is obliquely arranged, the lower end of the handle is welded on the steel plate at the upper part of the scraping plate, and an inclined strut is further arranged between the handle and the steel plate.
Further, the height control ruler is connected with the steel plate of the scraper upper plate part through two screws and locked to slide.
Further, a row of a plurality of height adjusting screw holes for adjusting the height of the height control ruler are obliquely downwards formed in the steel plate on the upper part of the scraping plate, and the distance between two adjacent height adjusting screw holes in the steel plate is the same as the distance between two screw holes in the height control ruler.
Further, the screw is a butterfly screw.
Further, the height control ruler is a steel ruler, and a zero scale line of the steel ruler is positioned at the lower end.
Compared with the prior art, the knife coater capable of controlling the thickness of the waterproof coating has the following beneficial effects:
in the utility model, the scraper blade is supported to a certain height by the height control ruler and the roller, so that the thickness of the coating film is controlled, a constructor is not required to control the thickness of the coating film by feeling, the coating of the coating can be efficiently finished, and the coating operation is allowed to be finished at one time.

FIG. 2 is a top view of a blade coater with a controlled thickness of water resistant coating according to the present utility model;
FIG. 3 is a schematic diagram of the connection of the blade to the height control scale;
in the figure, a 1-scraping plate, a 2-height control ruler, a 3-handle, a 4-roller, a 5-scraped area and a 6-height adjusting screw hole are shown.
Detailed Description
As shown in fig. 1-2, the scraper capable of controlling the thickness of waterproof paint comprises a scraper 1 and a handle 3, wherein a height control ruler 2 is arranged at the position of the scraper 1 outside a scraped area 5, the height control ruler 2 is attached to the scraper 1 and is in sliding connection with the scraper 1, a locking device for locking sliding is arranged at the sliding connection position, and the lower end of the height control ruler 2 extends out of the lower edge of the scraper 1;
the height control ruler 2 here lifts the blade 1 up to a certain height, which is the thickness of the paint film. The height control ruler 2 needs to be arranged outside the scraped area 5, avoiding influencing the scraped paint, and at the same time avoiding influencing the height adjustment by the paint.
The handle 3 is positioned outside the scraped coating area 5, the middle section of the handle 3 is also provided with a roller 4 for ensuring that the dip angle of the scraping plate 1 does not change along with the holding angle, and the roller 4 supports the scraping plate 1 together with the height control ruler 2.
The rollers 4 themselves have a certain width, so that the height control ruler 2 and the rollers 4 can still ensure that uneven thickness of the paint film is not caused by the fact that the scraping plate 1 is askew, although the scraping plate 1 is only supported on one side of one scraping plate 1.
The scraper 1 comprises a steel plate and a hard rubber plate which are arranged in a coplanar manner, wherein the lower edge of the hard rubber plate is contacted with the paint, and the upper edge of the hard rubber plate is inserted into the steel plate.
The scraper 1 is formed by a hard rubber plate and a steel plate, so that the scraping of the building base layer by the scraper 1 is avoided while welding can be ensured. The hard rubber plate can also be replaced by a hard plastic plate or a wood plate.
The handle 3 is a steel pipe which is obliquely arranged, the lower end of the handle 3 is welded on the steel plate at the upper part of the scraper 1, and an inclined strut is further arranged between the handle 3 and the steel plate.
The height control ruler 2 is connected with the steel plate of the upper plate part of the scraping plate 1 through two screws and locked and slid. The height control ruler 2 may rotate around the screw if a single screw is used, and the height control ruler 2 cannot be placed on more than two screws.
As shown in fig. 3, a plurality of height adjusting screw holes 6 for adjusting the height of the height control ruler 2 are obliquely and downwardly formed in the steel plate at the upper part of the scraper plate 1, and the distance between two adjacent height adjusting screw holes 6 in the steel plate is the same as the distance between two screw holes in the height control ruler 2.
We have tried to adjust the height of the height control ruler 2 with a vertical row of height adjusting screws, but found that it cannot be achieved at all because the thickness adjustment range of the paint film is small, smaller than the radius of the height adjusting screws, and the adjustment amplitude of the two height adjusting screws is too large even if they are next to each other, so we finally use the height adjusting screw holes 6 like that of fig. 3 after demonstration, thereby enabling fine adjustment.
The screw is a butterfly screw so as to be convenient to screw by hand.
The height control ruler 2 is a steel ruler, and zero graduation lines of the steel ruler are positioned at the lower end. If a softer ruler is used, the height control ruler 2 should be arranged on the side of the blade 1 close to the roller 4.
The utility model relates to a knife coater capable of controlling the thickness of waterproof paint, which comprises the following steps:
step one: the height of the height control ruler 2 is adjusted and fixed by screws;
step two: the present utility model is used to apply a water-resistant paint in the arrangement of fig. 2.
The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the present utility model.
