The printed pattern has three schemes, one is a horizontal pattern, and the printed pattern can be printed after the gypsum board is dried and solidified; one is to print a raised pattern, but since the gypsum board is a planar board, flatness is an important indicator, and the raised portions may cause a flatness error in the application of the gypsum board; and moreover, the concave patterns are printed, the flatness influence can not be generated during the use, but the gypsum board is large in brittleness after being dried, the concave patterns are easy to damage after being stamped, and the definition of the concave patterns can be greatly influenced when the board discharging speed of the gypsum board production line is very high. The gypsum board mainly comprises a paper gypsum board and a fiber gypsum board, wherein the paper gypsum board uses a piece of facing paper as a surface coating, the elasticity of the facing paper is very small, and if concave patterns are printed, the facing paper is damaged, so that the paper gypsum board is generally printed with horizontal patterns; the fiber gypsum board is also called as a paperless gypsum board, the surface of the fiber gypsum board is coated with fiber cloth, the board has the advantages of high density, strong mechanical firmness, waterproof and fireproof performances, particularly the elasticity of the fiber cloth is relatively high, and the flexibility of the fiber cloth is relatively high during thermal deformation, so that the process method for embossing concave patterns at the initial setting stage after the fiber gypsum board is molded and the matched molding machine are invented, compared with the existing pattern embossing process, the embossed patterns are clearer, the anti-counterfeiting is more facilitated, and the method is particularly suitable for medium-high speed production lines with the board discharging speed of the fiber gypsum board more than 20 meters/min.

The application relates to a fiber gypsum board embossing process:
firstly, mixing materials, namely accurately proportioning various raw materials for manufacturing the fiber gypsum board;
step two, preparing gypsum slurry, namely stirring the proportioned gypsum powder raw material and water into the gypsum slurry, and adding white latex as an additive in the stirring process to uniformly mix the gypsum slurry and the white latex;
step three, forming a fiber gypsum board, namely extruding and forming gypsum slurry and fiber mesh cloth into the fiber gypsum board by using a forming machine;
embossing a concave three-dimensional pattern on the upper surface of the fiber gypsum board, embossing the concave three-dimensional pattern on the upper surface of the initially set gypsum board by a high-temperature embossing module of an embossing wheel, enabling the upper fiber cloth to generate thermal deformation along with the shape of the three-dimensional mold during hot-pressing embossing, and smearing UV ink on the concave area by a UV module in the embossing wheel;
fifthly, rapidly solidifying the concave pattern area, conveying the fiber gypsum board into a solidification box, and carrying out irradiation of an ultraviolet lamp and heating by a heater to enable the concave area on the upper surface of the gypsum board to be rapidly solidified and molded, so that the fixing of the concave pattern is realized, and the rapid molding principle comprises rapid solidification of gypsum slurry at high temperature, rapid bonding of white latex at high temperature and rapid bonding of UV ink at ultraviolet irradiation.
Step six, cutting and drying, namely cutting the gypsum board in a fixed size, sending the gypsum board into a drying box for drying, and integrally drying the gypsum board with the concave patterns;
and seventhly, packaging and warehousing finished products, and stacking, bundling, laminating and warehousing the dried gypsum boards.
In the fourth step, the high temperature setting value of the embossing module of the embossing wheel is determined according to the physical properties of different fiber cloths, and the temperature range is controlled between the thermal deformation temperature and the melting temperature of the fiber cloths and does not exceed the high temperature failure temperature of the used UV ink.
When the fiber cloth on the upper surface layer of the gypsum board is pressed, the fiber cloth is deformed by heat along with the three-dimensional change of the indentation, so that burning damage cannot be formed.
In the step 4, the high temperature setting value of the embossing module of the embossing wheel is determined according to the physical properties of different fiber cloths, and the temperature range is controlled between the thermal deformation temperature and the melting temperature of the fiber cloths and does not exceed the high temperature failure temperature of the used UV ink.
The beneficial effects of the step 1 and the step 2 are as follows: the mixed gypsum raw materials are conveyed to the stirrer 110, water is added and stirred into gypsum slurry, meanwhile, white latex is added as an additive, stirring is continued to uniformly mix the gypsum slurry and the white latex, the white latex is used as a liquid additive, initial setting of the gypsum slurry is easier to accelerate when the gypsum slurry is heated, but if the gypsum slurry is directly added into solid gypsum raw materials, the phenomenon of uneven stirring is extremely easy to occur.
The step 3 is a process of manufacturing the gypsum board by a forming machine, and has the innovation point that two side ends of the traditional paper-faced gypsum board are wrapped by facing paper, slurry leakage is not easy to occur, and two end surfaces of the fiber gypsum board are open, so that a U-shaped forming belt is designed, after the gypsum slurry is scraped by a first step of a scraper, then a forming press roll extrudes and forms the gypsum board in a U-shaped groove of the forming belt, and the problems of slurry leakage and irregular side ends during forming of the fiber gypsum board without edge sealing at the side ends are avoided.
Wherein, step 4 and step 5 originally utilize the high-temperature impression wheel to press the gypsum board of initial setting, the gypsum material of initial setting has softness, will not disintegrate while pressing and forming; the high temperature causes the fiber cloth in the concave pattern area to generate thermal deformation, so that the concave pattern is not easy to recover elastically; the fiber cloth has certain light transmittance, and most of the fiber cloth is pressed into the surface layer of the gypsum board, so that the ultraviolet curing principle is utilized to smear UV ink on the concave pattern, and the UV ink is utilized to irradiate, so that the UV ink is rapidly adhered to the fiber cloth and the gypsum material in the cured pattern; simultaneously, the white latex is quickly solidified by irradiation of a radiation heat source, so that the gypsum material and the fiber cloth in the concave pattern area are quickly solidified; the process realizes the rapid solidification and molding of the concave pattern, the concave pattern is clear and vivid, and the UV ink can select a color type, so that the color concave pattern is stamped.
In the step 4, the high temperature setting value of the pressing module of the creasing wheel is determined according to the physical properties of different fiber cloths, the temperature range is between the thermal deformation temperature and the melting temperature of the fiber cloths, if the temperature exceeds the melting temperature of the fiber cloths, the fiber cloths can form burning damage in the high temperature pressing process, and if the temperature does not reach the thermal deformation temperature of the fiber cloths, the pressed concave patterns can be restored under the elasticity of the fiber cloths; meanwhile, the high temperature of the pressing module does not exceed the high temperature failure temperature of the used UV ink, otherwise, the UV ink loses the ultraviolet curing effect. The thermal deformation temperature and the melting temperature of different fiber cloths are not identical, and the high-temperature effective temperatures of different UV inks are also different, so that the high-temperature range of the pressing module needs to be determined according to the selected materials.
The working procedures of cutting, conveying, drying, packaging and the like in the production of the fiber gypsum board are the same as the corresponding working procedures of the paper-surface gypsum board.
