Problems solved by technology

[0003] The patent document EP0695812B1 proposes to form an insulating coating on the surface of the strip by means of dip coating, roller coating and spraying. The roller coating method mainly relies on the contact between the rotating roller and the strip. Due to the small contact area, it is difficult to ensure the integrity of the liquid film. coverage, it is difficult to ensure the consistency of the coating, further affecting the performance of the strip
[0004] It is difficult for the existing coating device to achieve a uniform and stable thickness of the insulating coating. In addition, in the process of brushing, the existing technology is to use the amount of liquid on the surface of the coating roller to roll coat the strip, so Insufficient precision in liquid volume control and liquid film control

Embodiment 1

[0058] The coating operation of the nanoside coil polysilitase solution was used to use the coating apparatus of the present invention. Image 6 The sprayed manner, the strip is from the feed port 2.2 into the coating chamber 2, the nozzle 2.2 spray the insulating material solution, by passing from the lower side of the fourth rotating roller 2.8, spraying the surface of the strip through the spray head 2.2 The subsequent strip passes from the bottom of the fifth rotating roller 2.9 and is bonded to the coating belt 2.7, and the direction of movement of the strip is opposite to the motion of the coating tape 2.7, which is designed to remove excess coatings on the back of the strip. Subsequently, the strip is moved in the direction of the discharge port 2.12 to the top of the first rotational roller 2.4 and the sixth rotational roller 2.10. The coating atmosphere is nitrogen, the first rotating roller 2.4, the second rotation roller 2.5, and the third rotation roller 2.6 are 60 mm, ...

Embodiment 2

[0061] The coating operation of nano-strip modified silica sol using the coating apparatus of the present invention is selected. Figure 7 The brushing method, the insulating substance solution does not have a portion of the third rotating roller 2.6, by the first rotational roller 2.4, the second rotation roller 2.5, the third rotation roller 2.7, can be taken 2.7 itself Liquid; the strip is from the feed port 2.1 into the coating chamber 2. The strip sequentially passes below the fourth rotating roller 2.8, and the bottom of the fifth rotation roller 2.7 is fitted with the coating belt 2.7, the direction of the strip and coating In contrast to the direction of movement of 2.7, the strip is separated by the strip and the coated belt 2.7, and then the strip is above the upper side of the first rotational roller 2.4, from above the sixth rotational roller 2.10, the discharge port 2.12. Directional movement. The coating atmosphere is argon, the first rotational roller 2.4, the second...

Embodiment 3

[0066] Using the apparatus of the present invention to carry out the coating operation of the nanocrystalline strip methyl silicone resin, Figure 8 The immersion method shown, the insulating substance solution does not have a portion of the third rotating roller 2.6; the strip is from the feed port 2.1 into the coating chamber 2, the strip is divided into the lower side of the fourth rotating roller 2.9, and the fifth rotation roller 2.9 Above, the direction of the strip 2.7 is bonded, the movement direction of the strip is the same as the moving direction of the coated belt 2.7, and the strip passes below the second rotation roller 2.5, and the third rotation roller 2.6 is immersed in the liquid surface or below the liquid surface. The surface belt liquid, and then the strip moves from above the sixth rotational roller 2.10, moves in the direction of the discharge port 2.12. The coating atmosphere is dry air (relative air humidity <1%), the first rotational roller 2.4, the second...

Abstract

The invention belongs to the field of coating, and particularly relates to a coating device. According to the coating device, multiple coating manners such as spray coating, brush coating and dip coating can be used, and continuous coating under a controllable atmosphere can be realized. A coating strip is creatively used, a liquid film on the surface of the strip can be complete and uniform, the strip liquid amount is controlled by changing the material of the coating strip, and the thickness of the liquid film attached to the strip is changed. In addition, the device further has the advantages of being high in coating efficiency, good in coating quality, uniform in coating, easy to operate, simple in structure, low in manufacturing cost and the like.

Description

Technical field [0001] The present invention belongs to the field of coating, and more particularly to a coating device. Background technique [0002] The amorphous nanocrystalline soft magnetic alloy has been found since the last century, due to its high initial magnetic permeability, saturated magnetic flux, resistivity, and Curie temperature, low coercive force, resistance temperature coefficient, and magnetostrictive coefficient. And the characteristics of corrosion resistance and anti-aging are widely used in power electronics. However, under some working conditions having high frequency, high power, high energy conversion, amorphous nano-alfangi magnetic rings will face severe eddy current loss, magnetic ring breakdown caused under high pressure conditions, the water is required for a long time Many problems such as magnetic ring erosion caused by the system. For the above problem, the currently mainstream method is to control the eddy current loss by increasing the insulat...
