The present invention relates to an aluminum alloy plate polishing apparatus using a triple surface polishing machine for polishing an aluminum alloy plate having a flattening operation through a leveling apparatus through a triple surface polishing machine.

Generally, a polishing machine is a device for performing a surface polishing process.

Surface polishing process is a process for manufacturing aluminum alloy plate with smooth and excellent gloss by grinding rough or discolored alloy ingot during the working process, and rotating rollers while moving aluminum alloy plate to conveyor belt horizontally. It is a process of grinding the surface of an aluminum alloy plate with the polishing cloth wound up and rotated on the outer peripheral surface of the.

The polishing machine is composed of a conveyor belt and a polishing unit for conveying the aluminum alloy plate.

The polishing unit is composed of an upper roller and a lower roller, and the polishing cloth is wound around the outer circumferential surface of the upper roller and the lower roller.

When the upper roller and the lower roller are rotated by a separately provided motor, the polishing cloth wound around the outer circumferential surface is rotated along the rollers, thereby polishing the surface of the aluminum alloy plate being transported along the conveyor belt at the lower portion thereof.

The surface polishing process is carried out in two stages, by first sanding the rough surface of the aluminum alloy plate using sand paper as the polishing cloth, and second polishing using a polishing cloth such as a loofah made of fabric, metal, or the like. The surface of the aluminum alloy plate can be flattened and given gloss.

Conventional grinders have two heads and are processed through two processes. Therefore, the surface of the aluminum alloy plate has a problem of having a rough surface or a large amount of residue. Also, when grinding, heat is generated to deform the plate and adhere to foreign matters. There was a difficult problem of polishing.

In addition, the loofah paper connection joint box 711 according to the present invention is composed of two scouring pad paper sensor for detecting the loofah paper on one side of the side wall located on the same line in the horizontal direction.

Here, the sensor for scrubbing paper consists of an electrical proximity sensor.

The scouring pads for the scouring pads are electronically sensed from the scouring pads, which are separated into two sets, and delivered to the third meandering air cylinder unit 700a-1 of the third left and right horizontal movement type meandering control unit 700a. In this case, the third meander adjusting air cylinder unit 700a-1 moves left and right to prevent the scrubber paper from being separated while rotating at a high speed.

The third upper idler roller 720 is positioned at the vertex of the third body having a triangle shape and serves to tension the top scrubber while rotating the scrubber paper.

In addition, the third upper idler roller 720 according to the present invention is horizontally moved horizontally in the left and right directions of the third upper idler roller at the end of the third main body at the lower end of the rotating shaft to the scrubber paper caused by the meandering cause. The third left and right horizontal movement type meander control unit 700a for adjusting the meander is configured.

The third main roller 730 is located at the lower right end of the third body of the triangle shape is rotated by the drive motor for the third main roller to transmit the rotational force to the neighboring third sponge roller and to rotate the scrubber paper, It is used to hold the scrubber paper in the right direction.

The third main roller 730 according to the present invention is composed of a rubber roller formed by protruding a non-slip rubber protrusion on the surface.

As shown in FIG. 10, the third main roller 730 is formed by winding a non slip tape 730a on a surface thereof.

Here, the non slip tape has excellent initial adhesive strength, strong humidity and water resistance, and has excellent weather resistance. Thus, non-slip tape can improve the adhesive force with the scrubber paper and can be polished with high quality. The surface of the aluminum alloy plate can be improved by 90% or more.

The third sponge roller 740 is positioned on one side of the third main roller and rotates according to the rotational force transmitted from the third main roller to directly contact and polish the surface of the aluminum alloy plate positioned on the third conveyor through a scrubber paper. do.

It consists of applying a soft sponge to the cylindrical roller surface.

The third lower idle roller 750 is positioned at the lower left of the triangle-shaped third body and rotates according to the rotational force transmitted from the third sponge roller to rotate the scrubber paper and to hold the scrubber paper to the left in tension. Do it.

In the third triangle roller unit according to the present invention, a third water spray nozzle 770 is formed at one side of both sides, and sprays water between the scrubber paper and the aluminum alloy plate to generate heat during grinding, thereby deforming and sticking to the aluminum plate. The phenomenon can be prevented.

Hereinafter, a specific operation process of the aluminum alloy plate polishing apparatus through the triple surface polishing machine according to the present invention will be described.

First, in order to adjust the height of the first triangle roller unit 500, the second triangle roller unit 600, and the third triangle roller unit 700 according to the thickness of the aluminum alloy plate, the upper frame lifting and lowering driving unit is driven.

Next, the aluminum alloy plate to be polished by the rubber belt conveyor 300 is introduced.

Subsequently, the first triangular roller unit 500 supports the surface of the aluminum alloy plate introduced on the rubber belt conveyor and is then ground first.

Subsequently, the second triangular roller unit 600 supports the surface of the first ground aluminum alloy plate, which is introduced into the rubber belt conveyor, and is secondly ground.

Finally, the third triangular roller unit 700 supports the surface of the secondary-grinded aluminum alloy plate introduced on the rubber belt conveyor and is then ground in the third triangular roller unit 700.
