Description

The compression molding systems duplication of plastics panel

The present invention relates to a double extrusion molding machine capable of producing a synthetic resin panel used for civil engineering synthetic resin panels, building interior and exterior panels and flooring, container flooring, marine flooring and the like. More specifically, the waste synthetic resin is used as the inner body, and a new nozzle is formed in a double extrusion molding machine for forming a synthetic resin waste material composed of the outer body to install a vacuum nozzle to release gas, thereby improving adhesion between the inner and outer bodies. The present invention relates to a double extrusion molding apparatus for a synthetic resin panel which can prevent an imbalance from occurring at both ends of the synthetic resin terminal by forming an incision for improving gas discharge.

Conventionally, there was a double extrusion machine using synthetic resin, but the existing molding apparatus does not have a big problem in double extrusion by using a new synthetic resin that does not use waste synthetic resin. In other words, when extruding only synthetic resin of new raw material (new material), melting point melting point, contact surface to be polymerized after double extrusion are made of the same material, so that adhesion is well achieved, and there is no problem due to the gas burned during heating in the molding machine. On the other hand, when the waste synthetic resin is used, the melting point of the new synthetic resin and the waste synthetic resin are different, so that the combustion gas is generated in the waste synthetic resin by adjusting the temperature to the melting point of the waste synthetic resin when heating in the same double molding machine. In other words, waste synthetic resins are used as waste plastics in rural areas, confectionery plastic bags in residential areas, etc., and the mixed waste resins are melted in a double heat extruder and burned beyond the melting point. Is generated. In this case, the adhesive force is reduced due to the difference in hardness between the generated gas and the surface of the junction of the waste synthetic resin and the surface of the new synthetic resin junction. There was a problem that deviated from the fundamental purpose.

For reference, the molten form of the resin that passes through the extruder when molding the double resin panel is not a completely molten liquid, but the resin is lumped with rice cake. Thus, a difference in adhesion occurs.

In the past, waste synthetic resins were extruded at a slow speed in the molding machine in the form of rice cakes, resulting in a decrease in production and imbalance of bonding. Therefore, waste synthetic resins cannot be utilized and the mixing ratio of new synthetic resin raw materials is increased. There is a problem that the closed product is not provided.

In addition, looking at the prior art in this field,

Patent No. 0459935 (called "Prior Art 1") "Floor material and a manufacturing apparatus of the container for freight transportation", as shown in Figures 1a to 1c, is a As the flooring material 14 of the container used for transportation, the outer element 141 is formed into a hollow flat plate through a series of extrusion process is assembled in association with the adjacent to the bottom surface of the container;

Replenishment element 142 is filled in the foaming process by using a recycled PE in the hollow of the outer element (141); And

And a coupling element adjacent to both sides of the outer element 141 in the longitudinal direction and having a coupling element 143 coupled to a male and female type,

As another embodiment, the inner wall of the outer element 141 made of a hollow plate body further comprises a plurality of reinforcing ribs (141a) are installed at equal intervals along the longitudinal direction thereof.

It can be seen that the flooring of the container for freight transportation consisting of a configuration comprising.

However, the prior art 1 has a problem that cannot be realized in the practice of producing a product. That is, the recycled PE transferred through each hopper 120 and the extruder 100 is melted and extruded into a hollow plate shape in the die 180 to form an external element, and the hollow portion of the external element formed in the plate shape. In forming the flooring material by filling the replenishment supplementary element 142, the external element having the hollow portion passes through the die 180 having the heating portion by using the raw material of recycled PE, but a large amount of combustion gas is generated. Filling element 142 is filled in the hollow part in a state in which the gas filled in the part is not discharged, so that a bubble layer is formed and the adhesive strength is weakened, and there is a problem in that the surface is irregular by the air layer even when sizing.

Further, Patent No. 0818342 (called "Prior Art 2") "Double Extrusion Apparatus of Synthetic Resin Panel" refers to an internal resin material which is extruded from the head of the first extruder (1) 4 of the double extrusion machine of synthetic resin.

There is a problem that can not be smoothly discharged. That is, in the related art 2, the gas generated from the resin passing through the outer guide hole and the inner guide hole of the double extrusion machine should be discharged to the gas distribution hole through a gap in which the discharge mold 11 and the external resin volume adjusting mold are combined. However, since the inner resin body is extruded in the form of rice cake, there is a problem of blocking a passage through which the gas generated by the inner resin body is blocked by a gap in which the discharge mold 11 and the outer resin amount adjusting mold are coupled.

In addition, in the prior art 2, a space is formed between the inner resin and the outer resin until the inner resin and the outer resin that pass through the ejection mold of the double extrusion machine enter the vacuum unit, and the space is formed in the waste synthetic resin. There is a problem that the gas can not be discharged because there is no separate outlet. That is, the external resin discharged from the discharge mold is discharged in the form of a rectangular tube, and the internal resin discharged in the form of a panel is discharged therein, so that the gas generated in the internal resin cannot be discharged in a sealed relationship by the external resin.
