[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator used for applying a magnetic paint in multiple layers.

[0002]

BACKGROUND OF THE INVENTION The production of a magnetic tape having a plurality of coating layers on a support may involve a process in which a lower magnetic layer is applied and dried, and then an upper magnetic layer is applied and dried. It is conceivable, however, that such a coating means increases the cost. Therefore, a means of simultaneous multi-layer coating similar to the production of a photographic film can be considered. However, the physical properties of the photographic emulsion paint and the magnetic paint are also different, and it has been found that it does not work even if the coater head used for the simultaneous multilayer coating of the photographic emulsion paint is used for the simultaneous multilayer coating of the magnetic paint.

[0003]

DISCLOSURE OF THE INVENTION A first object of the present invention is to provide an applicator which can effectively perform simultaneous multi-layer application of a magnetic paint. A second object of the present invention is to provide a coating apparatus which can easily perform simultaneous multi-layer coating of a magnetic paint not only in a mass production scene but also in a laboratory stage.

The object of the present invention is to provide a front wall, a rear wall, and a front wall.
A partition wall disposed between the front wall and the rear wall, and left and right
With an opening at the bottom,
Equipped with a partition wall height adjustment mechanism that can adjust the lower end height of the wall
Container, wherein the lower end of the rear wall is lower than the lower end of the front wall.
The height of the lower end of the partition wall is higher than the height of the front wall.
Higher than the lower end of the rear wall and lower than the lower end of the rear wall.
And the lower ends of the partition wall and the rear wall are tapered.
The present invention is achieved by a simultaneous multi-layer coating device for magnetic paint, which is formed in a taper shape having a taper angle of 0.2 to 3 ° .

[0005] Simultaneous multi-layer coating of a magnetic paint using the coating apparatus constructed as described above is better than simultaneous multi-layer coating using a coater head used for simultaneous multi-layer coating of a photographic emulsion paint. The thickness of the magnetic coating layer can be easily adjusted by adjusting the height of the lower end of the partition wall, and a quick change in the thickness of the coating film can be performed.

1 and 2 show an embodiment of the simultaneous multi-layer coating device for magnetic paint according to the present invention. FIG. 1 is a perspective view.
FIG. 2 is a side sectional view. In each of the drawings, reference numeral 1 denotes a container having a predetermined width, a predetermined length, and a predetermined height. As can be seen from FIG. It consists of left and right side walls 4,5.

As can be seen from FIG. 2, the relationship between the front wall 2 and the rear wall 3 is such that the lower end 2a of the front wall 2 is the same as the lower ends of the left and right side walls 4 and 5, but the lower end 3a of the rear wall 3 is left and right. Are configured to be higher than the lower ends of the side walls 4, 5. That is, the lower end 3a of the rear wall 3 is connected to the front wall 2 and the left and right side walls 4,5.
It is set so that it floats from the lower end of. The dimensional difference m is on the order of several tens to several hundreds μm.

Reference numeral 6 denotes a partition wall provided at an intermediate position of the container 1 in the front-rear direction, and the partition wall 6 is configured to be vertically movable. That is, the height of the lower end 6a of the partition wall 6 can be freely adjusted by adjusting the screws 7 provided through the outer surfaces of the left and right side walls 4 and 5. The lower end 6a of the partition wall 6
The height of the lower end 2 of the front wall 2 can be seen from FIG.
It is sufficient if the height can be adjusted within the range of the height between a and the lower end 3a of the rear wall 3.

The lower end 3a of the rear wall 3 and the lower end 6 of the partition wall 6
a is formed in a tapered shape as can be seen from FIG. The taper angles α ₁ and α ₂ are equal to or less than 45 ° and are equal to or less than 45 ° .
The angle is 2 to 3 degrees, and is 2 degrees in the present embodiment. Using the simultaneous multi-layer coating device configured as described above, the magnetic paint forming the lower magnetic coating is put into the first liquid reservoir 8, and the magnetic coating forming the upper magnetic coating is changed to the second coating. 2 and run at a predetermined speed in the direction of the arrow in FIG. 2, a magnetic coating layer having a thickness m ₁ is constituted by the magnetic paint flowing out of the _first liquid reservoir 8, and this thickness m is the magnetic coating layer having a thickness of m ₂ of a magnetic coating material flowing out from the second liquid reservoir 9 is configured on the magnetic coating layer of _1, the magnetic coating layer of two layers on a support It will be configured at the same time.

Furthermore, these magnetic coating layers are well formed, and can be applied better than when using a coater head used for simultaneous multi-layer coating of photographic emulsion paints. The thicknesses m ₁ and m ₂ of the magnetic coating layer can be adjusted very easily by adjusting the height of the lower end 6 a of the partition wall 6 by adjusting the screw 7.

Although the above embodiment has been described with reference to a single partition wall 6, a plurality of partition walls 6, such as two or three, may be used.

[0012]

[Effect] The simultaneous multi-layer coating device of the magnetic paint according to the present invention is:
A front wall, a rear wall, disposed between the front wall and the rear wall.
Partition wall, left and right side walls, opening at the bottom
The height of the partition wall which can further adjust the lower end height of the partition wall.
A container with an adjustment mechanism, wherein the lower end of the rear wall is
The lower end of the partition wall is configured to be higher than the lower end of the front wall.
The height is higher than the lower end of the front wall, and the rear wall
Lower than the lower end of the partition wall,
The lower end of the rear wall is tapered with a taper angle of 0.2-3 °
Since being formed to Jo, put each of the magnetic coating material to the liquid reservoir of each of magnetic coating material flowing out from each of the liquid reservoir by causing relative travel satisfactorily predetermined thickness magnetic coating layer Simultaneous multi-layer formation, magnetic coating can be applied simultaneously better than when using a coater head used for simultaneous coating of photographic emulsion paint, for example, and the thickness of each magnetic coating layer is also adjusted. It can be implemented very easily by adjusting the height of the lower end of the wall, and has the features that the implementation is extremely simple because of the simple configuration.
