Referring to fig. 1 to 3, a paint mold of the present invention includes a mold body 1;
the mould body 1 comprises a front side 11 and a rear side 12;
the die body 1 is provided with a plurality of coating grooves 2 which are arranged in parallel, and the bottom ends of the coating grooves 2 are provided with discharge holes 3;
the bottom of the front side 11 of the die body 1 is provided with a discharge chute 4 communicated with a discharge hole 3, the length of the discharge chute 4 is smaller than that of the discharge hole 3, and the edges and corners of the discharge hole 3 and the discharge chute 4 are provided with inclined chamfers 5.
The working principle of the invention is as follows: when the coating mould used, pour into coating in the coating groove 2, coating can follow the discharge opening 3 outflow of coating groove 2 bottom, paper along with the outside removes for the coating mould, coating can be from the discharge chute 4 by the knife coating on the paper surface at the removal in-process, discharge chute 4's effect lies in direction and pressure release, because the inside full paint of filling of coating groove 2, consequently coating groove 2 inside pressure is great, it scribbles coating groove 2 and external to set up discharge chute 4 intercommunication this moment, just can make coating follow discharge opening 3 under the effect of pressure and be extruded, the thickness of coating is unanimous with discharge chute 4's thickness and adheres to on the paper surface along discharge chute 4's direction, can guarantee the thickness of coating too thick and influence its adhesive force.
Wherein, the length of blown down tank 4 is less than the length of discharge opening 3, can guarantee that coating can not take place the diffusion to both sides to avoid adjacent coating to take place the contact, the edges and corners department at the position of discharge opening 3 and 4 intercommunications of blown down tank is equipped with the volume increase that chamfer 5 of slope can make discharge opening 3 department, and then makes the coating that holds in the discharge opening 3 more, guarantees that the coating of knife coating on the paper surface can not be too thin and can remain even and unanimous all the time.
As can be seen from the above description, the beneficial effects of the present invention are: the discharge chute not only can guide the coating, but also can relieve the pressure of the coating chute, so that the coating can be uniformly coated on the surface of the paper by blade coating from the discharge chute; the height of the discharge chute can limit the thickness of the coating, so that the thickness of the coating cannot exceed the thickness range required by the optimal adhesive force; the length of the discharge chute is smaller than that of the discharge hole, so that the coating can not diffuse to two sides, and adjacent coatings are prevented from contacting; the chamfer at the position that discharge opening and blown down tank communicate can guarantee that the coating of blade coating on the paper surface can not be too thin and remain evenly throughout.
Further, the height of the discharge chute 4 is smaller than 3 wires, and the inclination angle of the chamfer 5 is 15-30 degrees.
According to the description, the height of the discharge chute is smaller than 3 threads, so that the thickness of the coating flowing out of the discharge chute is smaller than 3 threads, the coating is ensured to have enough adhesive force, the coating is prevented from falling off from paper, and the diversion effect of the chamfer angle on the coating is the best within the range of 15-30 degrees.
Further, the coating material groove 2 is rectangular, the discharge hole 3 is located at the bottom of the coating material groove 2 on the side close to the front side 11 of the die body 1, the length of the discharge hole 3 is the same as that of the coating material groove 2, and the width of the discharge hole 3 is smaller than that of the coating material groove 2.
From the above description, it can be known that the width of the discharge hole is smaller than the width of the coating groove, so that the phenomenon that the coating is thick and spreads all around due to the excessive discharge amount of the coating can be avoided.
Furthermore, fillets are arranged at edges of the inner walls of the coating groove 2 and the discharge hole 3.
From the above description, when the fillet can make coating flow out from the discharge opening, the coating both sides can form the trend of adduction with the contact of fillet to further avoid coating to take place the diffusion to both sides.
Further, the bottom end of the coating material groove 2 is inclined downwards from the side far away from the discharge hole 3 to the side close to the discharge hole 3.
As can be seen from the above description, the downward inclination of the bottom end of the paint tank enables the paint to flow more smoothly toward the discharge hole.
Furthermore, the bottom end of the die body 1 is provided with a yielding groove 6, and the yielding groove 6 surrounds all the coating grooves 2.
According to the description, the contact area of the bottom end of the die body and the paper surface is greatly reduced due to the arrangement of the receding groove, and only the bottom end of the discharge hole can be in direct contact with the paper surface, so that the friction force between the die body and the paper surface is reduced, and meanwhile, the paper surface is prevented from being abraded.
Furthermore, the surfaces of the coating groove 2, the discharge hole 3 and the discharge groove 4 are all provided with hydrophobic coatings.
From the above description, the hydrophobic coating can prevent the paint from adhering to the surfaces of the paint layer, the discharge hole and the discharge chute.
A color card processing method comprises the following steps;
the method comprises the following steps: installing the coating mold on a color card printing device, and enabling the coated paper to pass through a gap between the bottom end of the coating mold and the color card printing device;
step two: firstly, conveying the coated paper between the bottom end of a coating mold and a color card printing device forwards at a constant speed by using a conveying mechanism on the color card printing device, adding a coating into a blanking hole of the coating mold, and uniformly attaching the coating to the coated paper from the bottom end of the blanking hole;
step three: and drying the coated paper with the paint by hot air, cooling and cutting to obtain the color card.
