Embodiment 1

[0018] Such as figure 1 , 2 As shown, a coating solution uniform distributor is provided with a liquid spray pipe 2 parallel to the coating roller 9 on the frame of the coating machine 7 near the oblique upper side of the coating roller 9, and the liquid spray pipe 2 The length is 600 mm, the inner diameter is 27 mm, and the liquid medicine can be dropped in the depression between the coating roller 9 and the metering roller 10 through the medicine spraying hole 1 .

[0019] A group of spraying holes 1 are evenly distributed along the length direction on the pipe wall of the liquid spraying pipe 2, the diameter of each spraying hole is 2 mm, and the inner and outer walls of the spraying holes are smooth and free of burrs. This is because if the diameter of the ejection hole is too small, the fluid will splash, and if it is too large, the factors of unbalanced fluid resistance will increase, which will cause flow imbalance. And the spacing of each spraying hole in the describ...

Abstract

The invention provides a uniform coating solution distributor. The uniform coating solution distributor is characterized in that a solution spray pipe (2) is arranged on a rack of a coating machine (7), a group of chemical spraying holes (1) are arranged in the solution spray pipe (2), one end of the solution spray pipe (2) is connected with a bend (4), a cushion gas cavity (5) is connected to the bend (4), the other end of the solution spray pipe (2) is connected with a solution supply pipe (3), and the other end of the solution supply pipe (3) is connected with a pump through a silicone hose (8). The uniform coating solution distributor is simple in structure and convenient to use, coating solution can be distributed in the length direction of a coating roll shaft uniformly, and no color difference of appearances of antireflection coating products produced in the process of solar antireflection glass manufacturing is ensured.

Description

Technical field: [0001] The invention belongs to the field of solar anti-reflection glass manufacturing. The utility model mainly relates to a coating solution uniform distributor in the manufacturing process of anti-reflection film by roll coating method. Background technique: [0002] In the manufacture of solar anti-reflection glass, the anti-reflection coating solution is generally applied on the surface of ultra-clear embossed glass by roller coating method. High-quality products must be achieved by uniform distribution of the coating solution in the longitudinal direction of the coating roller. Due to the small amount of coating solution supplied, there is no equipment to evenly distribute the solution, so there is color difference in the appearance of the product. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a coating solution evenly distributed in the longitudinal direction...
