Description
The present invention relates to a cooling device for a decorative flat plate extruder, and more particularly to a cooling device for a decorative flat plate extruder which comprises a cooling pipe To a cooling device for a decorative plate extruder capable of cooling by a primary indirect cooling through a heat exchange system through a smoothing roller and by a secondary air cooling method through a smoothing roller and improving the smoothness through a smoothing roller.
Generally, an extruder refers to a device for extruding an extruded material to form a product, and is roughly divided into a screw type extruder using a screw and a non-screw type extruder not using a screw.
The non-screw type extruder includes an Elastic Melt extruder, a Hydro-dynamic extruder, a ram type continuous extruder, or a gear type extruder.
The hydro-dynamic extruder is an extruder using a fluid principle of a thrust shaft bearing type (kingsbury or michell type), and the hydrodynamic extruder is an extruder using the fluid principle of the kingsbury or michell type. The continuous extruder is an extruder in which the two rams are combined in a direction opposite to the digesting extruder, and two extrusion rams and barrels are used in parallel to form a single unit.
The gear type extruder uses the principle of the gear pump for oil conveyance as it is for an extruder. This is an extruder in which three helical gears meshed with each other are arranged vertically so that the extruded material is fed from above and fed downward.
Using such an extruder, a decorative flat plate (PS flat plate or decorative board) is extruded and the formed decorative flat plate is cooled. That is, the decorative flat plate extruded from the extruder is cooled while being prevented from being deformed.
However, in the past, in order to cool the plate to be extruded from the extruder, a direct cooling method in which the water stored in the water tank is contacted with the decorative plate is cooled by allowing the water to pass through the water storage tank.
As a problem caused by such a direct cooling method, there is an inconvenience that water must first be filled in the water tank, and there is an inconvenience that it is necessary to wipe the water because the decorative plate touches the water.
In addition, there is a problem in that the size of the water tank is required to be different depending on the size of the decorative plate, and the temperature variation of the water contained in the water tank is deep and it is difficult to maintain the smoothness of the decorative plate. That is, the decorative plate is deformed.
