That is, the first relay gear 13a is arranged behind the drive shaft 13, and the second relay gear 15a meshes with the first relay gear 13a of the drive shaft 13 behind the driven shaft 15. Since the drive shaft 13 is interlocked with the drive shaft 13, the driven shaft 15 serves as an idle shaft.

In the styrofoam regeneration extrusion apparatus according to the present invention as shown in Figures 1 to 3, the pressing unit 20 is

The first and second screws 23 and 25 are arranged side by side adjacent to each other in the housing 21 and the pressure feeding space which is the inner chamber of the housing 21.

That is, the housing 21 cuts a portion of the cylindrical tube having a plurality of hollows, and in this case, the cut surface has a broken portion including a portion of the hollow of the tube,

When the cut surface of the two pipes cut in this manner is bonded to each other, the cross section of the housing is formed in such a manner that the Arabic numerals 'pal' or 'S' cross each other in reverse.

In this case, the first exhaust part 27 is provided along the longitudinal direction of the housing 21 at a portion where the cut surface joins the opened portion, that is, the 'pallet' or the 'S' intersection crossing each other. ,

The distance between the outer diameter and the outer diameter connecting the ends of each spiral wing with the base 27 therebetween is a separation distance L of '5 to 10 mm'.

This is because when the separation distance between the first and second screws 23, 25 is formed wider than the above range

The separation distance between the first and second screws 23 and 25 is so large that the styrofoam to be pushed and transported in this space stays, so that the pressure and transfer of the styrofoam is not made smoothly.

In addition, when the separation distance between the first and second screws 23, 25 is formed to be narrower than the above range

Since the separation distance between the first and second screws 23 and 25 is too narrow, the first exhaust part 27 of the housing for discharging the gas generated when the styrofoam is melted by the heating means 50 is provided with the first and second exhaust parts 27. Since it is relatively narrowed by the second screw 23, 25, the gas discharge is not made smoothly toward the hopper 33.
