Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a coating device used for multilayer coating of magnetic paint. It is.

0002

[Background of the idea]

In the production of magnetic tapes having multiple coating layers on a support, the lower magnetic layer is coated, After drying, it is also possible to go through a process where an upper magnetic layer is applied and dried. However, such application means are expensive. Therefore, simultaneous multilayer coating similar to that used in the production of photographic film may be considered. deer However, the physical properties of photographic emulsion paints and magnetic paints are different, and simultaneous multilayering of photographic emulsion paints is difficult. The same coater head used for coating may also be used for simultaneous multi-layer coating of magnetic paint. I have come to realize that this is not the case.

[Disclosure of invention]

The first purpose of this invention is to provide a coating device that can effectively apply multiple layers of magnetic paint at the same time. It is to provide. The second purpose of this invention is to use magnetic fields not only in mass production but also in the laboratory. To provide a coating device that can easily perform simultaneous multilayer coating of color paints.

0004 The object of the present invention is that the lower end height of the wall on the rear side is higher than that on the front side, and , a container with an opening configured at the bottom, a partition wall that partitions a space inside this container, and this partition. a partition wall height adjustment mechanism for adjusting the lower end height of the cut wall, the rear wall of the container; and magnetic paint characterized by the lower end of the partition wall being formed in a tapered shape. Accomplished by multi-layer application equipment.

[0005] In addition, the taper angle of the lower end of the rear wall or partition wall in the above simultaneous multilayer coating device The degree is preferably 45 degrees or less, more preferably within the range of about 0.2 to 3 degrees. It is preferable that Simultaneous multilayer coating of magnetic paint using the coating device configured as described above. is a simultaneous multilayer coating using a coater head used for simultaneous multilayer coating of photographic emulsion paints. The coating is better than layer coating, and it is also possible to adjust the height of the bottom edge of the partition wall. Therefore, the thickness of the magnetic coating layer can be easily adjusted, allowing quick response to changes in coating thickness. becomes possible.

【Example】

Figures 1 and 2 show an embodiment of the simultaneous multilayer coating device for magnetic paint according to the present invention. Therefore, FIG. 1 is a perspective view, and FIG. 2 is a side sectional view. In each figure, 1 is a container with a predetermined width, a predetermined length, and a predetermined height. As you can see, it lacks a bottom plate, and has a front wall 2, a rear wall 3, and left and right side walls. It consists of 4 and 5.

[0007] 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 on the left. Although the lower ends of the right side walls 4 and 5 are the same, the lower end 3a of the rear wall 3 is the same as the lower end of the left and right side walls 4 and 5. , 5. That is, the lower end 3a of the rear wall 3 is It is set to float above the lower ends of the square wall 2 and the left and right side walls 4 and 5. Furthermore, this The dimensional difference m is on the order of several tens to several hundred μm.

[0008] Reference numeral 6 denotes a partition wall disposed at an intermediate position in the front and back direction of the container 1; The wall 6 is configured to be movable and adjustable in the vertical direction. That is, the left and right side walls 4, 5 By adjusting the screw 7 penetratingly disposed from the outer surface of the partition wall 6, the lower end 6a of the partition wall 6 It is configured so that the height can be adjusted freely. Note that the lower end 6a of this partition wall 6 As can be seen from FIG. 2, the heights of the lower end 2a of the front wall 2 and the lower end 3a of the rear wall 3 are It would be good if the height could be adjusted within the range between.

As can be seen from FIG. 2, the lower end 3a of the rear wall 3 and the lower end 6a of the partition wall 6 are tapered. The taper angles α ₁ and α ₂ are angles of 45° or less, and are set to 2° in this embodiment. Using the simultaneous multilayer coating device configured as described above, the magnetic paint constituting the lower layer magnetic coating is placed in the first liquid reservoir 8, and the magnetic paint constituting the upper layer magnetic coating is placed in the second liquid reservoir 8. When the first liquid reservoir 9 is run in the direction of the arrow in _FIG . A magnetic coating layer with a thickness of m ₂ is formed on this magnetic coating layer with a thickness of m ₁ by the magnetic paint flowing out from the second liquid reservoir 9, and two magnetic coating layers are formed on the support. They will be configured at the same time.

Moreover, these magnetic coating layers were well structured and could be coated better than when using a coater head used for simultaneous multilayer coating of photographic emulsion coatings. Further, 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 6a of the partition wall 6 by adjusting the screw 7.

[0011] In the above embodiment, the case where the partition wall 6 is one is explained, but two or three partition walls 6 may be used. There may be more than one.

【effect】

The simultaneous multilayer application device for magnetic paint according to the present invention has a height of the lower end of the wall on the rear side than the front side. A container with a high height and an opening at the bottom, and the space inside this container. Equipped with a partition wall that separates the partition wall, and a partition wall height adjustment mechanism that adjusts the lower end height of the partition wall. , since the rear wall of the container and the lower end of the partition wall are formed into a tapered shape. , by putting each magnetic paint into each liquid reservoir and moving them relative to each other, each liquid reservoir becomes A magnetic paint layer of a predetermined thickness is simultaneously formed in a good manner by the magnetic paint flowing out from the For example, a coater head used for simultaneous multilayer coating of photographic emulsion paints is used. The magnetic paint can be applied in multiple layers at the same time, and the thickness of each magnetic paint layer can be reduced. The height can be adjusted extremely easily by adjusting the height of the bottom edge of the partition wall. It has the advantage of being extremely simple to implement because of its simple configuration.
