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:
The invention belongs to sun power anti reflection glass and manufacture field.Relate generally to a kind of coating liquid uniform device in rolling method antireflective coating manufacturing processed.
Background technology:
Sun power anti reflection glass manufactures, and the general rolling method that adopts is at energy ultrawhite figured glass surface-coated antireflective coating liquid.High-quality product, must be realized by coating liquid being uniformly distributed on film roll shaft length direction.Because coating liquid liquid supply rate is few, not yet there is the equipment use being uniformly distributed liquid at present, so product appearance exists aberration.
Summary of the invention:
The present invention is exactly to overcome deficiency of the prior art, provides one that coating liquid is uniformly distributed on film roll shaft length direction, ensures in sun power anti reflection glass manufacturing processed, the coating liquid uniform device of product appearance no color differnece.
The invention provides following technical scheme:
A kind of coating liquid uniform device, it is characterized in that: in the frame of coating equipment, a sparge pipe is set, uniform one group of insecticide-spraying hole along its length on the tube wall of sparge pipe, be connected with feed pipe in one end of sparge pipe, the other end of feed pipe is connected with the pump housing by silicone tube.
On the basis of technique scheme, following further scheme can also be had:
Be connected with elbow at the other end of described sparge pipe, elbow is connected with a buffering air cavity having extension tube and plug to form.
The spacing of each insecticide-spraying hole in one group of described insecticide-spraying hole 1 is within the scope of 2mm-60mm, and the diameter of each insecticide-spraying hole is within the scope of 1mm-2mm, and the inside and outside wall Glabrous thorn of squit hole.
Described sparge pipe internal diameter is in the scope of 20mm-30mm, and length is in the scope of 300mm-600mm.
Tetrafluoroethylene or polyethylene terephthalate is selected to manufacture sparge pipe.
The described pump housing is peristaltic pump.
The invention has the advantages that:
Structure of the present invention is simple, easy to use, and coating liquid can be made to be uniformly distributed on film roll shaft length direction, ensures that in sun power anti reflection glass manufacturing processed, the antireflective coated product appearance colorless produced is poor.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram that the present invention is arranged on coating equipment.
Embodiment:
Below by embodiment, the present invention is further detailed explanation.
Embodiment 1:
As shown in Figure 1, 2, a kind of coating liquid uniform device, in coating equipment 7 frame near oblique upper, film roller 9 side, a sparge pipe 2 parallel with film roller 9 is set, described sparge pipe 2 length is 600mm, internal diameter is 27mm, and liquid can drop in recess between film roller 9 and doctor roll 10 by insecticide-spraying hole 1.
Uniform one group of insecticide-spraying hole 1 along its length on the tube wall of sparge pipe 2, the diameter of each squit hole is 2mm, and the inside and outside wall Glabrous thorn of squit hole.If this is because squit hole diameter is too small cause fluid generation splash, excessive then because the unbalanced factor of fluid resistance rises, can cause that to cause flow unbalance.And the spacing of each insecticide-spraying hole in described one group of insecticide-spraying hole is at 20mm, if this is because anti reflection glass plated film amount of liquid medicine is generally 5400-39600ml/hr so squit hole spacing is less than 2mm in sun power anti reflection glass manufacturing processed, the rising of squit hole area can make the unbalanced factor of fluid resistance rise, and causes flow unbalance; And if squit hole spacing is greater than 60mm, squit hole flow velocity will be accelerated, and the fluid of ejection disturbance can occur, thus causes coated surface to occur moving towards a consistent optical skew band with glass.
Feed pipe 3 is connected with in one end of sparge pipe 2, the other end of feed pipe 3 is connected with the pump housing by silicone tube 8, and this is due to anti reflection glass plated film coating liquid, is generally to adopt a large amount of organic solvent as carrier, there is certain acidity, so usual silicone tube is by peristaltic pump feed flow.
And periodic jitter can be presented due to this feed liquid way, so be connected with elbow 4 at the other end of described sparge pipe 2, elbow 4 is connected with extension tube 4a straight up, plug 4b is provided with in the end of extension tube, thus form a buffering air cavity 5, thus play the object offsetting the pressure surge that wriggling feed flow produces.
Because the liquid carried in coating liquid uniform device mostly is organic solvent, to most of plastic pipe, there is solvability.Therefore, sparge pipe selects tetrafluoroethylene to make, this is because the resist dissolution that had liquid of tetrafluoroethylene and rare softening agent stripping.
