Accordingly, elevation means 13 is provided on the bottom surface of the preliminary washing tank 11.

The elevating means 13 can be variously modified. Preferably, as shown in Fig. 1, a cylinder equipped with a stretching rod which is stretched or contracted by hydraulic pressure or air pressure is used.

The upper portion of the preliminary washing tank 11 is provided with a preliminary cleaning roller brush 12 which is submerged in the washing water stored in the preliminary washing tank and installed in close contact with the first guide roller 101.

The pre-cleaning roller brush 12 is rotated by a driving means (not shown) as a means for removing foreign substances such as paint on the first guide roller 101 and the wire 100, And the foreign matter is separated.

Since the wire 100 washed by the preliminary washing unit 10 may contain foreign substances, the washing unit 20 may further include a washing unit 20 for washing the foreign substances more cleanly. Includes a main washing tank 21 and a plurality of main washing roller brushes 22f and 22e.

1, the main washing tank 21 includes a second guide roller 102, a third guide roller 103 and a fourth guide roller 103, which are filled with washing water and guide movement of the wire 100, A part of the lower portion of the washing water 104 is installed so as to be submerged in the washing water, and the wire is moved through the washing water.

The cleaning roller brushes 22f and 22e are rotatably provided so as to be in contact with the second guide roller 102 and the third guide roller 103 so as to remove foreign matter remaining on the wire, Thereby preventing the second guide roller 102 and the third guide roller 103 from being contaminated.

Further, the main washing unit 20 is further provided with a means for scraping off the foreign substances on the wire. A wire support rod 23 which is installed between the main cleaning roller brushes so as to be immersed in the cleaning water and which supports the bottom surface of the wire; And two cleaning blades 24f and 24e formed with a foreign material removing groove 24g.

5, the cleaning blade 24f or 24e is supported by the supporting bar 25 with the plate member having the foreign substance removing groove 24g formed at the lower end thereof, The body was made not to bend.

The means for scraping off the foreign matter is that the wire 100 passes through the foreign matter removing groove 24g and scraping off the foreign substances on the wire.

The foreign matter removing groove 24g preferably has a shape of a arc corresponding to the thickness of the wire.

The wire support bar 23 serves to prevent the wire from being pulled out of the debris removal groove 24g. It is preferable that the upper and both ends of the wire support rod 23 are not blinded to prevent the wire from being scratched and damaged while passing through the wire .

The height of the cleaning blades 24f and 24e is preferably such that the distance between the foreign matter removing groove 24g and the wire support bar 23 is equal to or less than the thickness of the wire.

The cleaning device according to the present invention is also provided with a drying unit 30. The drying unit 30 is installed on one side of a fourth guide roller for guiding and guiding the bottom surface of the wire, And a drying roller brush 31 for removing moisture.

The drying roller brush 31 preferably uses a brush or the like having a fast absorption of water as a solo, and is provided so as to be spaced apart from the water surface of the washing water stored in the washing tub 21 as shown in FIG.

4 and 6, the brushes 12, 22f and 22e constituting the cleaning device constructed as described above are formed by installing a cleaning brush 22b on the surface of the rotary shaft 22s, And the center line of the rotating shaft are preferably provided with an acute angle. This is because, when the brush is installed in a direction perpendicular to the rotation axis, the wire can not pass through the brushes between the brushes so that the foreign matter on the wire can not be sufficiently separated.

Further, it is preferable that the direction of rotation of the brushes 12, 22f, 22e, 31 is opposite to the direction of movement of the wire. This is because the bristles 12, 22f, 22e and 31 are rotated in the same direction as the moving direction of the wire, and when the moving speed of the wire is fast, the frictional force between the wire and the brushes may be reduced and the effect of separating foreign matters may be lowered.

In the cleaning apparatus of the present invention, the brushes are fixed at a predetermined position, but the frictional force between the brushes and the roller may be reduced depending on the aging state of the brush or the tension of the wire. At this time, the position of the brushes must be adjusted to adjust the friction force between the rollers and the brushes. To this end, the brushes are provided with the position adjusting means 40.

As shown in FIG. 6, the position adjusting means 40 includes a fixing bracket 41 having a fixing slot 41h formed therein so as to be horizontally positioned while being fixed to the frame; And a height adjusting rod 42 which is rotatably installed at one end and is screwed into a screw hole 41s formed in a direction perpendicular to the fixing bracket to adjust the height of the brush.

In other words, the horizontal position of the brushes can be achieved by changing the position of the slot through which the fixing bolt 43 is passed through the fixing slot to be fastened to the frame, and the height of the height adjusting rod 42 is adjusted to the screw hole 41s The tightening can be done by adjusting the height.
