Problems solved by technology

[0015] However, according to the existing paint coating device, the paint supplied to the coating tank and the paint box is not all coated on the passing wire (running line), and the remaining paint is passed through the paint circulation path without coating. Circulates in coating tanks, etc., so it is not suitable for coatings such as two-component types that deteriorate (harden) in a short time during circulation

[0033] (Structure of Paint Application System)

[0034] figure 1 It is a schematic configuration diagram showing the paint application system according to the first embodiment of the present invention.

[0035] The paint coating system 1 has: the paint coating device 10 that will be coated on the wire rod 3 by the paint 2 mixed by two liquids; the baking furnace 4 that is coated on the paint 2 on the wire rod 3 is dried; Pulleys (or rollers) 5A to 5D that have grooves for conveying the wire 3 on the outer peripheral surface through the paint coating device 10 and the baking furnace 4 multiple times (6 times in this case); the catalyst device installed on the baking furnace 4 6; the exhaust passage 7 installed on the exhaust port of the catalyst device 6 .

[0036] In addition, although illustration is omitted, an unillustrated winding machine and the like are provided behind the baking furnace 4 with respect to the wire rod 3 . In addition, in front of the pulley 5A, a core...

no. 2 approach

[0062] In this embodiment, in the paint application device 10 of the first embodiment, the L-shaped paint tank 30 is directly connected to the paint die instead of the pipes 20A to 20F, and other structures are the same as those of the first embodiment. In the following description, the same code|symbol is attached|subjected to the part which has the same structure and function as 1st Embodiment. In addition, in the present embodiment, although the L-shaped paint tank 30 is used, it is not limited thereto, as long as it is a paint tank having a shape that can smoothly supply the paint 2 to the coating dies 19A to 19F. The same effect can be obtained.

[0063] Figure 6 yes Figure 5 A top view of the paint tank shown, Figure 7 Viewed from the wire lead-in side Figure 6 Side view of paint tank shown.

[0064] The paint tank 30 forms a bucket shape with an upper opening. On the front wall 31 that is vertically combined with the side walls 38A and 38B and is arranged on th...

no. 3 approach

[0071] Figure 8It is a plan view showing main parts of a paint coating device according to a third embodiment of the present invention, Figure 9 yes Figure 8 A cross-sectional view of the paint application apparatus shown. Moreover, in Figure 8 In , a part of the pipeline is truncated.

[0072] In the second embodiment of the present embodiment, the paint tank 30 and the coating molds 19A to 19F are separately provided, and the two are connected by pipes 20A to 20F, and the front wall 31 of the paint tank 30 and the partition member 35 are inclined, Other structures are the same as those of the first embodiment. In addition, since the wire-passing method and coating method of the wire 3 in the paint coating apparatus 10 are the same as those of 2nd Embodiment, description is abbreviate|omitted.

[0073] According to the third embodiment, by providing the pipes 20A to 20F between the rear wall 33 of the paint tank 30 and the painting dies 19A to 19F, the amount of pain...

Abstract

A first varnish 11 supplied from a first varnish tank 12 and a second varnish 13 supplied from a second varnish tank 14 are mixed by a mixer 15 to provide a varnish 2, and supplied to a varnish bath 18 . Coating dies 19A-19F are connected to the varnish bath 18 via tubes 20A-20F. A wire 3 is installed into the coating dies 19A-19F through a hole 20a provided in each of the tubes 20A-20F. The varnish 2 supplied to the varnish bath 19 is dropped by its self weight through the tubes 20A-20F , and continuously supplied to the coating dies 19A-19F . The varnish 2 is applied to a surface of the wire 3 by the coating dies 19A-19F .

Description

technical field [0001] The present invention relates to a paint application device and a paint application method for applying paint to a wire. Background technique [0002] In the manufacture of enameled wires and other wires, a roll is dipped in a coating tank filled with paint, and the wire is continuously contacted with the upper surface of the roll to coat the wire with paint, and then the coated wire is dried in a baking oven. A paint manufacturing apparatus (for example, refer to Patent Document 1). [0003] In addition, there is also known a paint application device in which a paint guide plate, a protective plate, a sealing plate, and an inclined plate having a plurality of cutouts are stacked on one side of a paint box with an open upper end until the predetermined positions of the cutouts are filled with paint. Then, the paint is applied to the wire rod by passing the wire rod through the slit and passing the wire rod through the half-open hole partially formed i...
