Description

Composite Extrusion Panel Manufacturing Apparatus and Method for Construction {METHOD AND SYSTEM MANUFACTURING DOUBLE EXTRUSION PANEL FOR CONSTRUCTION}

The present invention relates to a double extrusion molding apparatus for synthetic resins that can be used as exterior panels for panels, flooring, container flooring, pedestals of logistics loading floors, flooring of aviation and ships, floors of loading boxes for trucks and the like.

More specifically, the first step of extruding the inner body of the waste synthetic resin, and the second extruding to polymerize the outer body of the new synthetic resin on the inner surface of the second synthetic resin, and again to form a waste synthetic resin layer on the new synthetic resin layer and a new synthetic resin layer on the waste synthetic resin layer It is possible to form multiple extruded panels formed by improving the strength and durability for impact absorption.

In addition, the present invention is to recycle the synthetic resin panel of various forms using waste plastic and waste plastic generated in farming and fishing villages or waste synthetic resin and waste plastic generated in industrial sites, etc. A construction double extrusion panel manufacturing apparatus and method for preventing contamination.

In modern society, various kinds of household goods and industrial goods are newly introduced and delivered to consumers as the industry develops.In particular, exaggerated packaging vinyl, food packaging vinyl, and mulching vinyl used for farming crops in farming and fishing villages are processed. It is one of the most problematic items in the world.

As of 2016, waste plastics, waste synthetic resins, and styrofoam are so low that they do not collect vehicle plastics at collection companies, and they do not collect waste plastics from apartments.

On the other hand, logging is extremely limited in the world, and plastic and synthetic resin products are increasing year by year, and all are used as new materials.

In particular, building materials, civil engineering materials, such as the supply of wood is reduced to meet the demand, the situation is replaced by synthetic resin products, there is a problem that the elasticity, tensile strength, such as wood falls.

In addition, in order to have durability against impact absorption when molding products using existing waste synthetic resins, there is a problem in that the efficiency of waste synthetic resins is decreased by producing a single product by mixing PVC raw materials with waste synthetic resins, and in particular, conventional waste synthetic resins. In order to produce a molded product using the waste to wash the soil on the collected synthetic resin and then to dry it again because the initial screening work is done by hand manually, there was a problem of managing labor costs as well as people.

Therefore, products recycled using waste synthetic resins cannot be activated in building products and civil engineering products, and very few wastes are mainly used in waste water pipes, sewage pipes, etc., and the remaining wastes are incinerated, thereby increasing the waste disposal cost.

Looking at the prior art in this field, Patent Application Publication No. 10-0789957 (Registration Date: December 21, 2007) "apparatus and method for producing a double extrusion panel using waste synthetic resin" (hereinafter referred to as "prior art") In a manufacturing apparatus for extruding a building member or flooring material using waste synthetic resin, a raw material for mixing raw materials of recycled PE and wood flour, rice hull, vermiculite, glass fiber and foamed material, which are pulverized by a conventional pulverizing device for collecting waste plastic waste vinyl. A mixer 1;

When the raw materials mixed in the raw material mixer 1 are supplied to the hoppers 3 and 3 ', the raw materials are melted by the plate heaters 4 and 4' wound on the outer surface at regular intervals, and the transfer screw 5 ( A first extruder 2 and a second extruder 2 'extruded to the head 6, 6' side by 5 '); The raw material extruded from the head portion 6 of the first extruder 2 is formed by the inner body 8, and the raw material extruded from the head portion 6 ′ of the second extruder 2 ′ is extruded from the outer body 9. A dual extrusion molding machine 7 formed of a plurality of rectangular blocks to form a synthetic resin panel 30 by adjusting the inflow amount of the outer body 9 with a plurality of control bolts 20 horizontally installed on upper and lower surfaces thereof;

A vacuum machine 12 for vacuuming the surface of the synthetic resin panel 30 formed by the double extrusion machine 7 made of the plurality of rectangular blocks is smoothly installed inside the front surface and a plurality of guides 16 on one side of the vacuum machine. A cooler 11 installed with a coolant to fill the coolant;

A drawer (17) having rollers (18) formed on both sides of the cooler (11) to draw and pull out the cured synthetic resin panel (30); Disclosed is an apparatus for producing a double extrusion panel using waste synthetic resin, characterized in that the cutter 19 is configured to cut the synthetic resin panel 30 withdrawn from the extractor 17 while moving a circular saw to a predetermined length.

In the prior art, since the supply of raw materials supplied to the dies is extruded to extrude the inner and outer bodies, a myriad of air layers are formed in the inner body, which is a waste synthetic resin, and the dies are extruded through the dies in a gel-like state. The thickness of the discharged synthetic resin panel is not uniform, and there is a problem in that the seam is generated by partially agglomeration.

In particular, the prior art includes a large amount of air layers because the waste synthetic resin material is supplied to the die in the molten state in the extruder, and the panel extruded from the die is pulled from the sizing to the vacuum due to the coexistence of the dense and unstructured parts of the tissue. In this process, a large amount of air layer is formed and in this process, since the structure is not uniform, the cooling density after vacuum is different, so that the shrinkage density is different. There is a problem.

In other words, even if the inner synthetic waste resin is melted in the extruder, it does not become a liquid state like a new synthetic resin but is formed like a rice cake, and a core is formed during extrusion, and the extrusion speed is slow.

These waste synthetic resins are not melted over a certain concentration even when heated and melted in an extruder, but are burned when the temperature is raised, so they have different physical properties from new synthetic resins. When moving to the extruded into a die by the extrusion force of the extruder in the same state as the lumpy rice cakes, there is a problem that the seam is different from the air layer and the melting point.

The prior art in this field described above is, in addition to the prior art, Patent Registration No. 10-1068947, Patent Registration No. 10-1166899, Patent Registration No. 10-0534050, Patent Registration No. 10-0645935, and the like. There is this. However, the above-listed prior arts also have the same problems described above, so that the production is not continuously made, and in particular, the prior art and the conventional double-extrusion panel forming apparatus using waste synthetic resins have the inner body as the waste synthetic resin and the outside. By using the sieve as a new material to be combined in one die (extrusion mold) to extrude, there is a problem that the extrusion speed is too slow to significantly reduce the productivity of the double extrusion panel.

In particular, the present invention is to improve the durability by enhancing the productivity efficiency and die air discharge, synthetic resin panel structure emerged as a problem in the conventional double extrusion panel using waste synthetic resin.

It looks at the manufacturing step by step according to the synthetic resin extrusion apparatus 1 having a multilayer structure of the present invention.

Step 1: blending and supplying raw materials

The raw materials used in the present invention are largely classified into two types. It is divided into waste synthetic resin constituting the inner body (A) and new synthetic resin raw material constituting the outer body (B).

The inner body (A) is a waste synthetic resin, made of mulching vinyl and confectionery plastic bags and waste synthetic resin generated after crop cultivation in farming and fishing villages, the outer body (B) is made of new synthetic resin.

Waste vinyl or waste synthetic resin, which is a raw material of the inner body (A) of the present invention, is collected and used as it is, even if soil or wood chips are mixed, without undergoing a separate washing process.

Waste synthetic resin and waste vinyl are dried, collected and pulverized to form a raw material. The waste synthetic resin material thus prepared is dried by hot air blowing from the heat supply fan 8 of the heater device 7 in the raw material blending feeder 2, and then the primary extruder 13 by the discharge conveyor 6. Is supplied.

At this time, in another raw material blending feeder 2, a new synthetic resin raw material is prepared and supplied to the second extruder.

The raw material blending feeder 2 for supplying the waste synthetic resin described in the present invention to the primary extruder 13 and the raw material blending feeder 2 for supplying the new synthetic resin to the secondary extruder 14 are each provided in the same configuration. .

The raw material blending feeder 2 is provided with a mixing hopper 12 provided on one side thereof, and the mixing hopper 12 and the raw material blending feeder 2 are provided with a feeding conveyor 3 and mixed in the mixing hopper 12. The raw material is supplied to the raw material blending feeder 2 by the supply conveyor 3.

The raw material blending feeder (2) is connected to the mixing hopper 12 and the raw material blending feeder (2) main body installed on one side to the raw material feed conveyor (3) and the conveyor drive motor (4) on top of the raw material feed conveyor (3) Installed to drive the feed conveyor (3).

In the center of the main body mixing feeder (2) the main body 11 is provided with a stirring shaft (9) having a stirring blade (10) is installed vertically to enable the stirring of the raw material and the drive motor (11) to rotate the stirring shaft on the stirring shaft (9) ) Is installed.

A heater device 7 having a hot air supply fan 8 is installed at one side of the raw material blending feeder 2 so as to dry the raw material inside the main body with hot air.

The hot air discharged from the heater device 7 is discharged to the inner lower portion of the raw material blending feeder to dry the raw material supplied from the discharge conveyor 6 to each extruder side to remove moisture and the like.

The raw material thus dried is supplied to the primary extruder 13 or the secondary extruder 14 by the discharge conveyor 6.

The raw material discharging conveyor 6 and the raw material supply conveyor 3 are respectively provided with a conveyor driving motor 4, 5 at the top thereof to drive a screw-shaped conveyor to transfer raw materials.

In addition, the mixing hopper 12 provided at one side of the raw material blending feeder 2 is horizontally provided with a stirring blade rotated by a motor at the lower end to stir the raw material contained in the hopper to be supplied to the supply conveyor 3.

Second Process: Raw Material Extrusion Step

The raw material blending feeder 2 is provided in plural, and the raw material blending feeder 2 on one side sends the melted raw synthetic resin material to the primary extruder 13 to melt, and the other raw material blending feeder 2 (shown separately) (Not shown) is sent to the secondary extruder 14 and melted.

The extruder used in the present invention uses an extruder to melt-extrude the synthetic resin, and the control unit is configured to electrically control the driving unit and the heater on one side, and a hopper is formed in the raw material input unit of the extruder, and the synthetic resin introduced from the hopper is transferred. A conveying screw is provided, and a plate-shaped heating device is installed on the outer surface of the screw so as to melt the synthetic resin raw material conveyed by the conveying screw.

The plate heating apparatus installed in each extruder is installed in proportion to the screw length of the extruder, but the heating temperature of the heating apparatus is installed to set the temperature differently for each section. The outer surface of the heating device installed as described above is formed so that a safety accident of the operator is not formed by the cover.

The extruder used in this process is provided with a primary extruder 13 and a secondary extruder 14, the primary extruder 13 to melt the waste synthetic resin to be supplied to the primary die 17, the secondary The extruder 14 can supply the primary die 17 to melt and stack the new synthetic resin.

The primary dice 17 and the secondary dice described later are provided so that the waste synthetic resin raw material and the new synthetic resin raw material can be supplied from the discharge conveyor 6 from each raw material blending feeder.

Third Step: Double Extrusion of Primary Synthetic Resin into Primary Die

The waste synthetic resin introduced from the primary extruder 13 is introduced into the primary die 17 through a transfer path 18 formed on the rear surface of the primary die 17.

The primary die 17 has a transfer path 18 formed on the front surface so that the primary die 17 can be divided into three in one passage.

That is, the discharge port of the primary extruder 13 and the front inlet transfer path 18 of the primary die 17 are connected, and the transfer path 18 thereof is formed as one inlet to the die inner extrusion part 15. The inflow portion is formed to be divided into three inflows.

In this way, the inlet of the first die 17 connected to the outlet of the primary extruder 13 is introduced into one of the conveying paths 18 and then divided into three pieces. Even though the waste synthetic resin is melted, it is in the form of a rice cake like flour dough. Since the extrusion speed of the panel flows into one passage at the same time, the extrusion speed of the panel is slow and at the same time the primary die 17 is filled with the inner extrusion part 15 so that the extrusion force is received only at the center part during extrusion. There is a problem that different pressures are generated so that the inflow passage of the waste synthetic resin is introduced through the three transfer paths so that the extrusion force inside the die has the same extrusion force as the center and both sides.

At this time, if the difference in the extrusion force of the waste synthetic resin is divided into three can be finely adjusted by using the inflow adjustment bolt 19 installed on the upper and lower portions of the primary die (17).

In this way, the waste synthetic resin introduced into the inner die extruded portion 15 through the primary die 17 through the primary extruder 13 has a plurality of hemispherical protrusions 20 formed on the inner circumferential surface of the extruded portion 15 of the primary die 17. In the process of repeating the tightening and loosening during extrusion, the same action as the dough is prevented, thus preventing the air layer in the waste synthetic resin and making the structure finer to prevent the formation of the core inside the waste synthetic resin.

That is, the inner wall of the primary die 17 forms a plurality of hemispherical protrusions 20 on the slopes to form curved concave-convex portions, so that the waste synthetic resin introduced through the primary extruder 13 is formed inside the primary die 17. In the process of passing, as if the stomach is digested by the human stomach, the air remaining inside the waste synthetic resin is discharged to the outside, and the tissue is luxury and becomes fine particles. It is possible to improve durability without being generated.

The primary die 17 has a configuration in which a plurality of rectangular blocks are coupled, and a heating device having a plate shape is installed at an outer surface thereof.

The inside of the primary die 17 is connected to the primary extruder 13, but divided into three transfer paths 18 in one transfer path 18 so that the waste synthetic resin is supplied into the primary die 13. , The second extruder 14 is connected to another new synthetic resin transfer path 18 ′ of the primary die 17 so that the waste synthetic resin and the new synthetic resin are overlapped in the first die 18 and double-bonded to the front surface. The die 17b is extruded to the discharge port.

The secondary extruder 14 has the same configuration as the primary extruder 13, and receives the raw material from the raw material blending feeder 2 like the primary extruder 13, melts while passing through the screw, and then the primary die ( It is formed inside the primary die 17 in the form of being encapsulated on the outer surface of the waste synthetic resin extruded in 17) is discharged to the mold die 17a of the primary die 17 and flows into the primary sizing 21.

The primary die 17 has a plurality of air vents are formed in the upper and lower to exhaust the air generated therein to the outside.

Fourth step: forming a plurality of hollow parts in the double extrusion panel

The synthetic resin double panel extruded through the mold die 17b of the primary die may be formed without forming a hollow portion, but forms a plurality of hole-shaped hollow portions to increase strength and durability.

In order to form the hollow portion, an elliptical hole-forming rod 27 having a cross section is installed to be fitted into the mold die 17b which is the discharge portion of the primary die 17.

In this case, the hole forming rods 27 are equally disposed laterally equally in the mold die 17b so that a plurality of holes are formed in the inner body A of the double synthetic resin panel, which is the extrudate 34 discharged.

The hole forming rod 27 is fixed so that one end of the hole forming rod 27 is inserted into the inlet opening of the mold die 17b, but the hole forming rod 27 is coupled to be detachable.

The hole forming rod 27 is formed in an elliptical cross section, and is installed so that the larger diameter is located on the vertical line when installed in the mold die 17b discharge port.

The hole forming rod 27 is formed to be coupled to the groove formed in the inlet inlet of the mold die (17b) is formed so that the engaging projection is formed on one side end in order to attach to the discharge port. That is, the protrusions formed at one end of the hole forming rod 27 are inserted into grooves formed in the upper and lower portions of the inlet opening of the mold die 17a, and then rotated to one side to be coupled to each other.

In addition, the hole forming rod may form a pin hole without forming a protrusion at one end thereof and insert the pin hole into a discharge hole of the mold die 17a, and then fix the pin through the pin at an upper surface of the mold die 17a.

As described above, when a plurality of hole forming rods 27 are horizontally installed at the discharge hole of the mold die 17a, a plurality of holes are formed in the double synthetic resin panel that is extruded from the primary die 17.

Fifth Step: Primary Sizing Step of Vacuum Forming

The extrudate of the double synthetic resin extrusion panel in which the plurality of holes are formed by the hole forming rods installed in the mold die discharge port of the primary die is sucked by vacuum in the primary sizing 21 to smooth and smooth the outer surface of the panel. ) Mold.

The primary sizing 21 for vacuum forming has a space such as a tunnel so that the synthetic resin double extrusion panel can be introduced and transported to the other side, and a plurality of vacuum holes are formed therein to form the synthetic resin double extrusion panel at the top and the bottom thereof. Adsorption vacuum to smooth the outer surface.

At this time, the primary sizing 21 for vacuum molding is composed of one unit, but internally, the partition 22 is formed at a half point to be divided into the primary vacuum unit 25 and the secondary vacuum unit 26. Compartment.

The primary sizing 21 is just after the double panel extruded from the primary die 17 is out of the hole-forming rod 27, so that the vacuum pressure is weakened so that the surface vacuum is achieved and the secondary vacuum portion 26 is formed. While passing through the vacuum pressure hard to form the hole and the overall shape is fixed.

Since the shape of the hole formed in the hole forming rod 27 is immediately after leaving the hole forming rod, the egg is placed upright, so that only the surface of the primary vacuum unit 25 is vacuumed weakly, and the second size of the primary sizing 21 is again. A plurality of holes penetrating the inner body (A) of the panel by vacuum is performed in the secondary vacuum section 26 to form the mold.

That is, when the hole of the panel inner body extruded from the primary die 17 is formed into a circular shape from the beginning, when passing through the primary sizing 21, the shape of the hole is not formed of a garden but is formed as a crushed circle, so that the hole forming rod has a cross section. This elliptical rod is installed so that the larger diameter is located on the vertical line so as to be circular in the vacuum in the primary sizing 21.

In the present invention, when the new synthetic resin is used in the extrusion molding of the panel with the synthetic resin, the holes formed inside are formed without deformation during extrusion, but when the waste synthetic resin is used, the hole is formed like a rice cake, Since the deformation occurs in the shape of the hole, in the case of the waste synthetic resin, it is necessary to install a hole forming rod in consideration of forming a hole such as a circle, a rectangle, a rectangle, and an oval.

In the present invention, forming the partition wall 22 in the primary sizing 21 and dividing it into the primary vacuum unit 25 and the secondary vacuum unit 26 to vacuum forming is well formed in the hole of the panel to be vacuum formed. Although there is a reason to make the waste synthetic resin, the extrusion speed is slowed down, so if the vacuum pressure in the first sizing 21 is weakened and the vacuum pressure is increased in the secondary vacuum part 26, the extrusion speed at which the panel is moved is increased. You can do it faster and increase your productivity.

In addition, the primary sizing inlet is wide in the front and narrow in the back and inclined inward to the upper and lower sides such as " " so that the panel extrudate extruded from the primary die can be easily introduced into the primary sizing 21. Part C was formed to facilitate the inflow of the extruded panel.

At this time, the panel extrudates extruded from the primary die should be filled in a consolidation form at the inlet when the inlet flows into the primary sizing so as to form a panel during vacuum in the primary sizing to prevent unevenness and unbalance.

When the primary inlet is drawn in a consolidation form at the inlet of the primary sizing, the primary extractor installed at the rear is pulled in and consolidates along the inclined surface at the primary sizing inlet.

The primary sizing is a conduit is formed around the vacuum hole to circulate the refrigerant to cool the sizing.

6th process: primary vacuum cold forming and water cooling step

The shape of the extruded panel smoothed from the primary sizing 21 is passed through the primary vacuum cooler 30 to fix and cool the deformation so that deformation does not occur in the cooling process.

The primary vacuum cooler 30 is installed at the head of the water cooling device formed in a chamber form to cool the dual panel that is extruded and transferred from the primary size 21.

In this case, as the panel extrudate passes through the first sizing, the external shape is formed by a double extrusion panel, but since the cooling is not completely done, the external shape is completely hardened in the primary vacuum cooler and the primary water cooler to deform the external shape. To prevent them.

The primary vacuum cooler 30 is composed of upper and lower cooling plants 31 and 32 and the upper cooling plant 31 is configured to be moved up and down by a cylinder.

In addition, the upper and lower cooling plants are adsorbed and cooled so that a vacuum hole is formed at the bottom of the synthetic resin double panel which is transported to one side so as not to interfere with movement and deformation does not occur during cooling.

At this time, the vacuum in the primary vacuum cooler 30 is weakened and completely fixed so that deformation does not occur in the shape, and cooling is performed by the refrigerant of the primary vacuum cooler itself.

Maintaining the smoothness in the primary vacuum cooler 30 as described above, the primary cooled synthetic resin double panel is moved in the state submerged by the moving rollers installed in the primary water cooling device (35).

At this time, the primary water cooling device 35 may install a vibrator on one side of the tank to vibrate the water so that the water rumbles like a wave in the tank, thereby further increasing the cooling effect.

In addition, the present invention can be cooled by spraying water by installing a plurality of rollers in the water tank of the primary water cooling apparatus to be moved while being guided by the roller double extrusion panel extruded by the water spray nozzles installed in the upper and lower parts.

When the primary water cooler is cooled by filling with water, the primary vacuum cooler 30 and the primary water cooler 35 are installed by installing a partition so that the primary vacuum cooler installed at the tip does not interfere with the vacuum. Install it.

In this process, the synthetic resin double panel passed through the primary water cooling device 35 is cured to form a complete panel.

That is, since the panel which has passed through the cooling water is completely cooled and no deformation occurs, there is no problem in using the panel or the panel which is not cut to a predetermined standard.

Thus, the panel which passed the primary water cooling apparatus 35 is called primary extrusion panel 34 in this invention.

7th step: moisture removal and withdrawal step

The water sprayed on the surface of the primary extrusion panel 34 cooled by the primary water cooling device is removed by the air spraying device 36.

Since the primary extrusion panel cooled through the primary water cooling device 35 is wetted with water, the external extrusion panel is dried by an air injector 36 because the external water must be dried for a subsequent process.

In addition, the primary ejector 37 is installed on the same line behind the air injector 36 so that the synthetic resin supplied from the primary extruder 13 and the secondary extruder 14 passes through the primary die 17 and is primaryly sized. 21, the primary vacuum cooler 30, the primary water cooler 35, and the air injector 36. At this time, the extrudate is discharged by the extrusion force pushed from the primary extruder and the secondary extruder to the discharge portion of the primary die, and is moved by the pulling force pulled from the primary extractor after the primary sizing.

Step 8: preheating the primary extrusion panel in the heating chamber and forming the multilayer panel in the secondary dice

The primary extrusion panel 34, which is pulled from the primary extractor 37 and transported, is introduced into the heating chamber 38 to dry the moisture remaining on the surface of the primary extrusion panel 34 and soften the surface.

The heating chamber 38 is installed in front of the secondary die 41 to heat and soften the outer surface of the primary extrusion panel 34 which is drawn into the secondary die 41 so that the primary extrusion panel 34 is 2nd. Bonding with the synthetic resin supplied from the 3rd extruder 39 and the 4th extruder 40 in the tea die 41 is made.

In this case, if the surface of the primary extrusion panel 34 is not softened in the heating chamber 38, the adhesive strength is weak when the secondary die 41 is laminated with the synthetic resin, thereby causing a problem in that the multilayer joint of the completed multilayer synthetic panel is opened. As a result, the primary extrusion panel 34 must soften the surface in the heating chamber 38 device.

The primary extrusion panel 34 whose surface is heated from the heating chamber 38 is introduced into the secondary die 41 and the waste synthetic resin supplied from the tertiary extruder 39 is laminated on the outer surface to form a waste synthetic resin layer. And the new synthetic resin supplied from the fourth extruder 40 is laminated on the waste synthetic resin layer to form a multi-layer structure.

As described above, the panel laminated in a multilayer structure in the secondary dice 41 is discharged from the secondary dice 41 and then transferred to the secondary sizing 42.

The tertiary extruder 39 carried out in this step receives waste synthetic resin raw materials from a raw material blending feeder installed on one side, and is melted in the tertiary extruder 39 and injected into the secondary die 41.

In addition, the fourth extruder 40 is supplied with a new synthetic resin raw material from a raw material blending feeder installed on one side, melted in the fourth extruder 40, and injected into the secondary die 41.

Accordingly, when the primary extrusion panel 34 passing through the heating chamber 38 enters the secondary die 41 in the secondary die 41, the waste synthetic resin supplied from the tertiary extruder 39 is the primary extrusion panel. Laminated and extruded on the outer surface, a new synthetic resin supplied from the fourth extruder 40 is laminated on the outer surface of the laminated waste synthetic resin layer is extruded from the secondary die 41 and molded into a multilayer extrusion panel.

The secondary dice 41 need not form hemispherical protrusions 20 like the primary die 17 inner extrusion portion.

The secondary die 41 is formed of a minja inside, so that when the primary extrusion panel 34 is drawn in, the waste synthetic resin layer and the new synthetic resin layer are laminated and extruded on the outer surface.

The secondary dice 41 are coupled to a plurality of blocks like the primary dice 17 and a plate heater is installed on an outer surface thereof.

In addition, synthetic resin inflow adjustment bolts are respectively installed on the upper portion of the secondary dice 41 to adjust the amount of waste synthetic resin and new synthetic resin.

Process 9: second sizing

The secondary sizing 42 vacuums flat and smooth the extruded panel formed in multiple layers in the secondary dice 41.

The secondary sizing 42 carried out in this step smoothes the outer surface of the multilayered synthetic resin panel extruded from the secondary dice 41 with a vacuum.

The secondary sizing 42 is configured to vacuum the multilayer synthetic resin panel at a time without dividing the primary vacuum portion 25 and the secondary vacuum portion 26 like the primary sizing 21.

The secondary sizing 42 is also formed with an inclined surface such as " " " inwardly as the primary sizing 21 so that the multilayered synthetic resin panel extruded from the secondary die 41 can be easily inserted. It was.

10th step: vacuum cooling and water cooling

The multi-layered synthetic resin extrusion panel smoothed from the secondary sizing 42 is cooled in a secondary vacuum cooler 43 and a secondary water cooler 44 which vacuum cool so that the shape is fixed upon cooling.

In this process, the secondary vacuum cooler 43 is installed at the front end of the water tank, and is made up of a plurality of rollers to be filled with water, or spray nozzles are installed at the upper and lower parts to constitute the secondary water cooler 44.

The secondary vacuum cooler 43 has the same configuration as the primary vacuum cooler 30 described above, and the cooling forming plants 31 and 32 are formed in the upper and lower parts, and the upper cooling forming plant 31 is a cylinder. The lower and lower cooling forming plant is connected to the lower and the plurality of vacuum holes are formed.

Therefore, the multilayer synthetic resin panel transferred from the secondary sizing 42 is not completely cooled, but may be deformed upon cooling, thereby cooling while holding the appearance with a vacuum.

The multi-layer synthetic resin extrusion panel passing through the secondary vacuum cooler 43 is precipitated and cooled in water or cooled by water sprayed from a plurality of nozzles in the process of being guided and transported by a roller in the same water tank.

When the multi-layered synthetic resin extrusion panel is moved in a state where water is stored in the water tank of the secondary water cooling device 44, the cooling efficiency may be increased by applying vibration to the water contained therein.

Process 11: Cooling, Cutting and Banding

The multi-layered synthetic resin extrusion panel is cooled in the secondary water cooling device 44 and then drawn out by a draw-cold molding machine installed in the same line and sent to a cutter.

The multi-layered synthetic resin extrusion panel drawn out from the take-out cooling molding machine 45 includes a cutter 49 for cutting to a predetermined standard and a banding machine for bending the cut multi-layer extrusion panel to a predetermined number.

10 is a schematic view showing a connection state in which the primary extrusion panel extruded from the primary die of the present invention is extruded in multiple layers from the secondary die.

FIG. 10 shows the primary extrusion panel 34 by extruding the waste synthetic resin and the new synthetic resin supplied from the primary and secondary extruders 13 and 14 in the primary die 17. In the primary extrusion panel 34, waste synthetic resin constitutes an inner body (A), and new synthetic resin forms an outer body (B) to form a double extrusion panel.

As such, the primary extrusion panel 34 formed in the primary die 17 extrudes the waste synthetic resin and the new synthetic resin supplied from the tertiary extruder 39 and the fourth extruder 40 in the secondary die 41. A resin extrusion panel having a multilayer structure is formed.

10, therefore, omits the steps between the primary and secondary dice and briefly illustrates an embodiment of the primary and secondary dice.

For reference, in the present invention, the extrudate extruded from the primary die is vacuum extruded in the primary sizing, and the extrudate continuously moved is referred to as a primary extrusion panel 34 for convenience, and the article produced by cutting the double extrusion panel ( 50).

In addition, the panel is completely cooled after passing through the cooling process from the primary die to the binary die is referred to as a multilayer extruded panel (51).

11 is a step-by-step view showing the primary panel shape extruded from the primary die and the secondary panel shape formed from the secondary die of the present invention, the primary extrusion panel constituting the inner body (A) and the outer body (B) Before the 34 is extruded from the primary die 17 and drawn into the primary sizing 21, as shown in FIG. Is formed.

The primary extrusion panel 34 extruded from the primary die 17 has a rectangular cross-section such as ⒝ when drawn into the primary sizing 21 and adsorbed by vacuum in a state having a convex curved portion as shown in Fig. The surface is shaped smoothly.

The primary extrusion panel 34 vacuum-adsorbed in the primary sizing has a primary vacuum cooler 30, a primary water cooling device 35, an air spraying device 36, a drawer 37, and a heating chamber 38. When the waste synthetic resin and the new synthetic resin are laminated from the third extruder 39 and the fourth extruder 40 in the secondary die 41 and discharged from the secondary die 41, the primary extrusion is performed as shown in FIG. The resin laminated on the panel 34 is extruded in a state where a curved portion is formed in a cross section, and then made through a second size 42 to have a rectangular cross section, and the surface is smoothly molded to have a multi-layered synthetic resin extruded panel. Is formed.

That is, the primary dice 17 and the secondary dice 41 of the present invention are discharged in the shape of convexly convex in the form of curved upper and lower parts and then molded into the correct shape in each sizing.

In concrete terms,

Since the waste synthetic resin raw material is introduced into the die in the primary extruder 13, a foam layer is formed in the raw material due to the gas, and thus the raw material does not uniformly spread in the primary die 13.

Therefore, in order for the product to spread well throughout the die, it is necessary to knead the dough in the dice so that the raw material spreads well in the first die so that the strength of the whole part is the same.

delete

In addition, since the raw material is a waste synthetic resin, when the square product is formed in the die, the product is foamed due to the gas and the product is folded like a steamed bread when it comes out of the first die. Make it slightly curved so that the product is inserted well into the primary sizing (21) without riding the dice.

In addition, in order to make a large number of holes 52 formed in the inner body of the primary extrusion panel 34 in the shape of an egg, a hole forming rod 27 is formed between the primary die 17 and the primary sizing 21. Extrude so that 52 is formed.

In addition, in order to prevent the extruded panel from being swollen like a steamed bread, a plurality of holes 52 may be crushed, the new synthetic resin must be laminated on the product once more to form a rectangular shape, and the strength is formed and the flatness is smooth.

Immediately afterwards, as the extrudate of the panel enters the primary sizing 21, only the surface is weakly formed while the primary vacuum and the primary vacuum section 25 are subjected to the primary cooling and vacuum to form a square shape. A large number of holes (C) are made without sticking to the product, and the hole forming rods 27 are immediately pulled out, gradually vacuuming and cooling in the first vacuum unit 25 and strong cooling and vacuuming in the secondary vacuum unit 26. As the whole square is made, the hole C and the foam layer of the product are formed, and thus the strength is strongly formed in the product.

12 is a cross-sectional view showing a number of hemispherical protrusions formed inside the primary die according to the present invention, and the waste synthetic resin raw material flowing from the primary extruder flows into the central transfer path 18 of the primary die and is divided into three sections. It flows into the primary die 17 through the conveying path 18.

In this way, the waste synthetic resin is divided into three after the waste synthetic resin is introduced into one conveying path 18. Since the waste synthetic resin has a rice cake shape in the molten state as kneading flour, the raw material is injected in one conveying path. When extruding, not only the extrusion speed is lowered but also the space is suddenly widened when entering into the primary die 17 in one narrow passage, so that the extrusion force is applied only to the center portion, and both side portions have an unbalanced extrusion rate.

In order to solve this disadvantage, the present invention forms three divided passages (transfer passages) after being introduced into one passage (transfer passage) to uniformly extrude the raw rice cake-type waste synthetic resin material in the primary die 17. To be possible.

In addition, the primary die 17 of the present invention is to form a plurality of hemispherical protrusions 20 on the upper and lower left and right inner surface to form a waste synthetic resin raw material during extrusion.

That is, the waste synthetic water support material is rubbed by the hemispherical protrusion 20 when extruded from the primary die 17, thereby acting to gelatinize the raw material and release the internal gas.

Particularly, the waste synthetic resin extruded in the primary die 17 serves to improve durability of the molded panel by preventing particles from being broken down and forming cores in the process of kneading, as shown by a hemispherical protrusion 20. .

According to the present invention, a panel extrudate extruded from the primary die 17 is formed by installing a hole forming rod 27 between the mold die 17a of the primary die 17 and the primary sizing 21. In the process of drawing into the primary sizing 21 in 17b), a plurality of holes 52 are formed in the inner body of the extrusion panel.

One end of the hole forming rod 27 may be fixed to the mold die 17b of the primary die 17 or may be fixed to the pin 29.

The end of the hole forming rod 27 is inserted into the mold die (17b) is formed in a pointed shape so that the extrudate is not disturbed during extrusion, and the other end is located in the primary sizing inlet and fixed with a pin or the like.

The primary sizing 21 has a wall 22 formed therein and is divided into a primary vacuum part 25 and a secondary vacuum part 26, and the primary vacuum part 25 passes through the hole forming rod 27. The vacuum pressure is set weakly so that only the surface of one extrudate is sucked in vacuum, and the secondary vacuum section 26 is set to vacuum in the world than the vacuum pressure of the primary vacuum section 25.

The primary sizing 21 has a plurality of vacuum holes are formed in the upper and lower inner surface and the pipeline is formed inside the body to move the cooling water to cool the heat of the extrudate to prevent sticking during vacuum adsorption and to increase the extrusion movement speed To be able.
