The first compression unit 110 includes a plurality of first cylinder bodies 111 each having a length in a horizontal direction, a first rod 112 coupled to the plurality of first cylinder bodies and linearly reciprocating in a horizontal direction, And a first compression plate (113) coupled to an end of the first rod, wherein the first cylinder body is coupled to an outer surface of the first housing, the first rod and the first compression plate A part of which passes through the side surface of the first housing and is linearly reciprocated within the first housing in a state of being coupled to the one cylinder body.

Accordingly, the first compression unit compresses the scrap introduced into the first housing in the horizontal direction.

At this time, the pressure at which the scrap is compressed by the first compression unit is 130 to 170 kgf / m and the optimum pressure is 150 kgf / m.

If the pressure at which the scrap is compressed by the first compression unit is less than 130 kgf / m, the scrap is not compressed well. If the pressure exceeds 170 kgf / m, the scrap is hardened to a certain extent and cracks may occur in the scrap There is a disadvantage.

The second compression unit 120 includes a plurality of second cylinder bodies 121 each having a length in a vertical direction, a second rod 122 coupled to the plurality of second cylinder bodies and linearly reciprocating in a vertical direction, And a second compression plate (123) coupled to an end of the second rod, wherein the second cylinder body is coupled to an upper surface of the first housing, and the second rod and the second compression plate are connected to a second A part of which passes through the upper surface of the first housing in a state of being coupled to the cylinder body and linearly reciprocates within the first housing.

The fourth compression unit compresses the scrap to form a puck shape at a pressure of 230 to 270 kgf / m and an appropriate pressure of 250 kgf / m.

If the pressure at which the scrap is compressed by the fourth compression unit is less than 230 kgf / m, the scrap is not transferred to the discharge unit. If the pressure exceeds 270 kgf / m, a crack occurs before the scrap is transferred to the discharge unit, .

The lower surface of the guide body 211 communicates with the lower surface of the second housing 200.

In addition, a hole 211-1 is formed in the outer circumferential side of the guide body 211 so that the scrap compressed in the first housing can be inserted.

Then, when the third rod of the third compression section moves in the scrap direction and the third compression plate moves the hexagonal scrap to the second housing, the scrap is formed with a hexahedron-shaped hole, and thereafter the first compression section When the compression plate and the second compression plate of the second compression unit are pressed again to fill the holes formed in the scrap, the scrap is formed into a hexahedron shape having a volume smaller than the volume of the scrap previously compressed by filling the holes formed in the scrap, Continue until the scrap is exhausted.

Also, when the scrap injected into the first housing is consumed, a certain amount of scrap is injected into the hopper by the conveyor.

In step 5, the scrap is compressed in the vertical direction inside the second housing to move the scrap compressed in the form of a puck to the discharge part. By the fourth compression part installed in the second housing, the scrap is puck ), And the scrap compressed by the fourth compression unit is discharged to the lower portion of the second housing.

When the hexagonal scrap is moved into the fourth compression section of the second housing by the third compression plate of the third compression section in step 4, the scrap is broken inside the guide body in the shape of the hollow body and is compressed again.

The compressed scrap is formed into a puck shape by the fourth compression plate of the fourth rod of the fourth compression unit, and is discharged to the discharge unit.

In step 6, the scrap compressed in the form of a puck is conveyed to the conveyor, and the scrap in the form of a puck discharged to the lower part of the second housing is conveyed to the conveyor by the discharge part.
