Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating apparatus for applying paint to wire strips, and more particularly to a coating apparatus suitable for manufacturing enamelled insulated wires having a multiple insulation structure.

FIG. 1 is a front sectional view of a conventional paint applicator, and FIG. 2 is a side sectional view thereof.

1 is a paint application tank, which includes a frame 2, a partition plate 3, a paint leakage prevention packing 4, a packing holder 5, a die holder 6,
It is composed of die 7.

The bare conductor W is a coating tank 81 partitioned by a partition plate 3.
At this point, paint E is applied and then applied, and this operation is repeated several times to form an insulated wire.

Furthermore, the bare conductor wire W2 is similarly coated with the paint E several times in the coating tank 9 to become an insulated wire.

When manufacturing double-coated insulated wires using such a conventional paint applicator, as shown in FIG. , and then the paint E2 is further applied and baked.

For this reason, when manufacturing single-coated insulated wire,
Although it was possible to manufacture two insulated wires, when manufacturing a double-coated insulated wire, only one insulated wire could be manufactured, resulting in a problem of reduced work efficiency.

The present invention has been made to address the above-mentioned problems, and the object of the present invention is to manufacture a paint coating device that can efficiently manufacture insulated wires having a multiple insulation structure by only slightly improving a conventional paint coating tank. be.

An embodiment of the present invention will be described below with reference to FIG. 1 is a first paint coating tank, and a conventional coating tank can be used as is.

1 river is a second paint application tank, and the first paint application tank 1
An elongated hollow tube body 11, a die 12, and a packing 1 passing through the
3.

Paint E2 is supplied to the hollow tube body 11 from the paint tank 14 via the hollow tube body 15, and the paint E2 is applied when the conducting wire W passes through the hollow tube body 11. That will happen.

Therefore, in the first paint coating tank 1, the paint E is applied onto the circumference of the conductor wire W, and then in the second paint coating tank, the paint E2 is applied to produce a double-coated insulated wire. .

Note that 16 is a flow rate regulating valve for the paint E2.

Further, in order to obtain a multiple insulation structure with double coating or more, it is sufficient to arrange several units identical to the second paint coating tank 10.

As described above, according to the present invention, by simply adding a very simple device, it is possible to manufacture insulated wires with a multi-insulation structure even in the conventional 1/2 inch paint application space, greatly improving manufacturing efficiency. improve.
