A coating equipment that eliminates the color difference of wallpaper by using the shaking of the fuselage

Abstract

The invention relates to the technical field of wallpaper printing and coating, and discloses coating equipment for eliminating wallpaper chromatic aberration through machine body shaking. The coatingequipment comprises a shell body. The interior of the shell body is movably connected with a supporting frame, the bottom of the supporting frame is movably connected with rollers, the surface of thesupporting frame is fixedly connected with a hollow passageway, the portions, located on the two sides of the hollow passageway, of the surface of the supporting frame are movably connected with airflow boxes, and the interior of the hollow passageway is fixedly connected with an air-liquid tank. Instant impact force generated when pigments make contact with wallpaper is large, airflow within thecontact range can be disturbed, part of the airflow can enter the hollow passageway, at the same time, a shaking plate regularly swings along with the supporting frame, the airflow can be introducedinto the hollow passageway through swinging motion and then exhausted from air holes, the airflow has a certain flow rate after being affected by the shaking plate, as the flow rate of the airflow islarge, force on the surfaces of pigment skin films can be increased, bubbles are broken, and the effect of eliminating the bubbles is achieved.

Description

technical field [0001] The invention relates to the technical field of wallpaper printing and coating, in particular to a coating device that eliminates the color difference of wallpaper by using body shaking. Background technique [0002] Wallpaper, also known as wallpaper, is a kind of interior decoration material used to paste walls. It is widely used in the interior decoration of houses, offices, hotels, hotels, etc. Like other decoration materials, wallpaper is constantly changing with the development of world economy and culture. Development and change. [0003] The production process of wallpaper is: paste, coating, drying, cooling, printing, etc. For the coating and printing process of wallpaper, there is often a phenomenon of inconsistent color difference between left and right. The reason is that in the process of pigment filling, due to The viscosity of the pigment is high, the surface tension of the pigment is high, and the gas in the pigment is difficult to esc...

[0003] The production process of wallpaper is: paste, coating, drying, cooling, printing, etc. For the coating and printing process of wallpaper, there is often a phenomenon of inconsistent color difference between left and right. The reason is that in the process of pigment filling, due to The viscosity of the pigment is high, the surface tension of the pigment is high, and the gas in the pigment is difficult to escape from the pigment film and stay in the ink layer, thereby generating air bubbles in the pigment, resulting in the paint or pigment not being evenly sprayed from the spraying equipment during printing

[0004] In the prior art, a vibrating device is usually installed on the inner bottom of the trough to eliminate air bubbles. The vibrating device vibrates to float and eliminate the bubbles in the liquid paint. However, most of the troughs are designed with a groove-shaped structure. Therefore, the range of vibration is limited, and it is difficult to achieve the effect of defoaming; in addition, if the pigment is still for a long time, it will produce flocculent substances at the bottom, which will affect the quality of coating printing. Equipment came into being
