Description

Field of the Invention [0001] The present invention relates to an apparatus and a method for manufacturing a composite extrusion panel for a building,

The present invention relates to a double extrusion molding apparatus for a synthetic resin which can be used as interior and exterior panels for construction, flooring, container flooring, pedestal of a logistics floor, flooring of air and ship,

More specifically, the inner body of the waste synthetic resin is first extruded and extruded so that the outer body made of the synthetic resin is polymerized on the outer surface of the inner body, and a waste synthetic resin layer is formed on the synthetic resin layer. Thereby forming a multi-extruded panel having improved strength and durability against shock absorption.

The present invention also relates to a process for recycling waste synthetic resin by forming various types of synthetic resin panels using waste vinyl and waste plastics generated in farming and fishing villages or waste synthetic resin and waste plastics generated at industrial sites, The present invention relates to an apparatus and a method for manufacturing a double extruded panel for construction.

In modern society, as the industry develops, various kinds of daily commodities and industrial goods are introduced to the consumers. In particular, exaggerated packaging vinyl, food packaging vinyl, and mulching vinyl used for cultivating crops in the farming village It is one of the most problematic items in.

As of 2016, waste plastics, waste plastic, and styrofoam are so low prices that they do not collect the vehicle cost for collecting by collection companies, and they do not collect the waste plastics from each apartment.

On the other hand, logging is extremely limited worldwide, and plastics and synthetic resin products are increasing every year, and they are used as raw materials for new materials.

In particular, building materials and civil engineering materials have a problem in that they are not replaced with synthetic resin products because they are unable to meet demand due to a decrease in the supply of wood, and they are inferior in stretchability and tensile strength such as wood.

  In addition, in order to have durability against shock absorption when molding a product using a conventional waste synthetic resin, there is a problem in that the efficiency of the waste synthetic resin is lowered by producing a monolithic product by mixing the PVC raw material with the waste synthetic resin, In order to produce molded products using the waste synthetic resin, it is necessary to clean the collected waste synthetic resin and dry it again, so that the initial sorting operation is performed manually by hand.

Therefore, the product recycled using the waste synthetic resin is not activated in building products and civil engineering products, and there is a problem that the waste treatment cost is increased by partially using some of the waste mainly in wastewater pipes, sewage pipes and the like.

Prior art of this field is disclosed in Korean Patent Registration No. 10-0789957 (registered on Dec. 21, 2007) entitled " Apparatus and Method for Producing Double Extruded Panels Using Waste Synthetic Resins " A production apparatus for extruding a building member or a bottom material by using a waste synthetic resin, comprising: a raw material for mixing raw materials of recycled PE crushed by a conventional crushing apparatus for collecting waste plastic waste vinyl and raw materials of wood, rice hull, vermiculite, 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-like heaters 4 and 4' (2) and a second extruder (2 ') for extruding the extrudate (5) to the head part (6) or (6') side; The raw material extruded from the head portion 6 of the first extruder 2 is formed into the inner body 8 and the raw material extruded from the head portion 6 'of the second extruder 2' A double extrusion molding machine 7 having a plurality of rectangular blocks to form the synthetic resin panel 30 by adjusting the inflow amount of the external body 9 with the adjustment bolts 20 provided on the upper and lower sides,

A purge air 12 is provided inside the front surface so that the surface of the synthetic resin panel 30 formed by the double extrusion molding machine 7 composed of the plurality of rectangular blocks is smoothly smoothed and a plurality of guides 16 A cooler (11) provided with cooling water;

An ejector 17 having rollers 18 formed on both sides of the synthetic resin panel 30 so as to pull out the synthetic resin panel 30 cured by the cooler 11; And a cutter (19) for cutting the synthetic resin panel (30) drawn out from the drawer (17) so that the circular saw can be cut to a predetermined length while moving.

Since the prior art is a method in which the supply of the raw material supplied to the dice is pushed out to extrude the inner body and the outer body to extrude, an innumerable air layer is formed in the inner body of the waste synthetic resin and is extruded through the die in the state of gel, There is a problem in that the thickness of the discharged synthetic resin panel is not uniform according to the texture, and the core is partially formed.

Particularly, in the prior art, since the raw material of waste synthetic resin is supplied to the die in the state where it is melted in the extruder, it contains many air layers and the dense portion and the non-dense portion of the structure coexist so that the panel extruded from the die is pulled from the siphon to the vacuum In this process, a large amount of air layer is formed, and since the structure is not uniform, the shrinkage density becomes different as a result of cooling after vacuum. Thus, the thickness of both side edges and the central part are not uniform, .

That is, even if the inner synthetic resin is melted in the extruder, it is not formed in a liquid state like a new synthetic resin but is formed like a soft and fluffy rice cake, so that a core is formed at the time of extrusion and the extrusion speed is slow.

Such a waste synthetic resin is not melted at a certain concentration or more even if it is melted by heating in an extruder, but it is burned if the temperature is raised. Since pure synthetic resin, especially waste vinyl, is used in the extruder, There is a problem in that a core having a melting point different from that of the air layer is generated inside the die due to the extrusion of the die by the pressure output of the extruder in the same state as a soft rice cake.

In addition to the above-described prior arts, the prior art of the above-described field of application includes patent registration No. 10-1068947, patent registration No. 10-1166899, patent registration No. 10-0534050, patent registration No. 10-0645935 . However, the above-described prior arts have the same problems as described above, and thus, they are not continuously produced. Particularly, in the prior art and the conventional double extrusion panel molding apparatus using waste synthetic resin, The extrusion speed is too slow due to the fact that the sieve is extruded from a single die (extrusion die), resulting in a problem that the productivity of the double extruded panel is remarkably reduced.

Hereinafter, embodiments of the present invention will be described in detail.

As described above, the present invention relates to a synthetic resin plywood panel for a wood substitute having a multi-layer structure in which an inner body (A) molded from a waste synthetic resin material and an outer body (B) composed of a raw material for a synthetic resin are repeatedly polymerized.

In particular, the present invention improves durability by enhancing productivity efficiency, air exhaustion of dies, and synthetic resin panel structure in a double extrusion panel using a conventional waste synthetic resin.

A process for manufacturing steps according to the synthetic resin extrusion molding apparatus 1 having a multilayer structure of the present invention will be described.

Step 1: Blending of raw materials and feeding step

The raw materials used in the present invention are roughly classified into two types. The inner body A is divided into a raw synthetic resin material constituting the constituent waste synthetic resin and the outer body B.

The inner body A is a waste synthetic resin, which is made of plastic for mulching, a plastic bag and a waste synthetic resin, which are generated after cultivation of crops in farming and fishing villages, and the outer body B is made of a new material synthetic resin.

The waste vinyl or waste synthetic resin which is the raw material of the inner body (A) of the present invention is not used for the separate cleaning process but is used as it is even if the soil or wood pieces are mixed.

The waste synthetic resin and the waste vinyl are dried and pulverized to form a raw material. The waste synthetic resin material thus prepared is dried by the hot air blowing from the heat supply fan 8 of the heater unit 7 in the raw material mixing feeder 2 and then discharged into the primary extruder 13 by the discharge conveyor 6. [ .

At this time, a raw material for synthetic resin is prepared in another raw material feeder (2) and supplied to a secondary extruder.

The raw material compounding feeder 2 for supplying the waste synthetic resin to the primary extruder 13 and the raw material compounding feeder 2 for supplying the raw material synthetic resin to the secondary extruder 14 are provided in the same configuration .

The mixing hopper 12 and the raw material mixing feeder 2 are provided with a feed conveyor 3 and are mixed in a mixing hopper 12, The raw material is supplied to the raw material mixture feeder 2 by the feed conveyor 3.

The raw material mixing feeder 2 has a mixing hopper 12 and a main body of the raw material mixing feeder 2 connected by a raw material feed conveyor 3 and a conveyor drive motor 4 is connected to an upper end of the raw material feed conveyor 3 And drives the supply conveyor 3.

A stirrer shaft 9 having a stirring blade 10 is vertically installed at the center of the main body of the raw material mixing feeder 2 so that the raw material can be stirred and a driving motor 11 Is installed.

A heater device 7 having a hot air supply fan 8 is installed at one side of the raw material mixing feeder 2 so that the raw material in the main body can be dried by hot air.

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

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

The raw material discharge conveyor 6 and the raw material supply conveyor 3 are provided with conveyor drive motors 4 and 5 at the upper end thereof to drive the screw type conveyor to transfer the raw material.

The mixing hopper 12 provided at one side of the raw material mixing feeder 2 is provided with a stirring blade rotated horizontally by a motor at a lower end thereof so that the raw material contained in the hopper is stirred and supplied to the feed conveyor 3.

Second step: raw material extrusion step

A plurality of the raw material mixing feeders 2 are provided so that one raw material mixing and feeding device 2 feeds the supplied waste synthetic resin raw materials to the primary extruder 13 for melting and feeds them to the other raw material mixing and feeding device 2 ), The new synthetic resin is sent to the secondary extruder 14 and melted.

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

The plate-shaped heating device installed in each of the extruders is installed in proportion to the screw length of the extruder, and the heating temperature of the heating device is set so that the temperature can be set differently for each section. The outer surface of the heating device thus formed is formed so that a safety accident of an operator is not generated.

The extruder used in this process is provided with a primary extruder 13 and a secondary extruder 14. The primary extruder 13 melts the waste synthetic resin to supply it to the primary die 17, The extruder 14 can supply the primary dies 17 so that the new material synthetic resin is melted and laminated.

The primary dies 17 and the secondary dies to be described later are installed so that the waste synthetic resin material and the raw material synthetic resin material can be supplied from the discharge conveyor 6 from the respective raw material mixing and supplying devices.

Step 3: Double extrusion molding of primary resin into primary dies

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

The primary die 17 is formed with a feed path 18 so that the primary die 17 can be dividedly supplied in three paths from 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 to each other. The transfer path 18 is formed as one inlet and is connected to the die inner pushing portion 15 And the inflow portion is formed so as to be divided into three portions.

 The reason why the inlet of the primary die 17 connected to the discharge port of the primary extruder 13 is introduced into one of the three transfer paths 18 after being introduced from one transfer path 18 is that even if the waste synthetic resin is melted, The extrusion speed of the panel is delayed and at the same time is filled with the inner extrusion portion 15 of the primary die 17 so that the extrusion force is applied only to the central portion during extrusion, So that the inflow path of the waste synthetic resin is introduced through the three transfer paths so that the pressure output inside the die has the same pressure output at the center portion and both side portions.

At this time, if the difference in the output power of the waste synthetic resin that is divided into three parts is generated, fine adjustment can be performed using the inflow amount adjusting bolt 19 installed at the upper and lower portions of the primary die 17.

The waste synthetic resin introduced into the inner extrusion 15 of the primary die 17 through the primary extruder 13 passes through the plurality of hemispherical projections 20 formed on the inner peripheral surface of the extruded portion 15 of the primary die 17 ), It acts like kneading in the process of repeating the operation of tightening and loosening by extrusion. Therefore, the air layer in the waste synthetic resin is prevented, and the fine structure of the waste synthetic resin is prevented to prevent the core from being formed inside the waste synthetic resin.

That is, the inner wall of the primary die 17 forms a plurality of hemispherical protrusions 20 on the slope surface to form curved recesses, so that the waste synthetic resin introduced through the primary extruder 13 flows inside the primary die 17 In the course of passing, as the stomach is digested as if the stomach is digested, the air remaining inside the waste synthetic resin is discharged to the outside, and the tissue becomes luxurious and becomes fine particles. Therefore, So that the durability can be improved.

The primary die 17 has a structure in which a plurality of rectangular blocks are combined and a plate-shaped heating device is installed on the outer surface thereof.

The inside of the primary die 17 is connected to the primary extruder 13 and is divided into three transfer paths 18 in one transfer path 18 so that the waste synthetic resin is supplied into the primary die 13 And the secondary extruder 14 is connected to another new material synthetic resin conveying path 18 'of the primary die 17 so that the waste synthetic resin and the new material synthetic resin are doubly overlapped in the primary die 18, And is extruded to the discharge port of the die 17b.

The secondary extruder 14 has the same structure as the primary extruder 13 and is supplied with the raw material from the raw material mixing feeder 2 like the primary extruder 13 and melted while passing through the screw, 17 in the form of being inserted into the outer surface of the waste synthetic resin extruded from the primary die 17 and discharged into the mold die 17a of the primary die 17 and introduced into the primary sieve 21. [

A plurality of air vents are formed in the upper and lower portions of the primary die 17 to exhaust the air generated in the primary die 17 to the outside.

Step 4: Step of forming multiple hollows 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 the hollow portion, but a plurality of hole-shaped hollow portions are formed in order to increase the strength and durability.

In order to form the hollow portion, the hole forming bar 27 having an elliptical cross section is installed so as to be fitted in the mold die 17b which is the discharging portion of the primary die 17.

At this time, the hole forming rods 27 are arranged horizontally evenly inside the mold dice 17b so as to form a plurality of holes in the inner body A of the double synthetic resin panel, which is the extrudate 34 discharged.

The hole forming bar 27 is coupled to the hole of the discharge port of the mold die 17b so that one end of the hole forming rod 27 is inserted and fixed while the hole forming rod 27 is detachably attached.

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

The hole forming bar 27 is formed at one end of the hole to be attached to and detached from the discharge port so as to be fixed to the groove formed in the discharge port inlet of the mold die 17b. That is, the protrusion formed at one end of the hole forming rod 27 is coupled to the groove formed at the upper and lower portions of the outlet of the mold die 17a, and then the protrusion is rotated.

Further, the hole forming bar may be formed with a pin hole at one end thereof without forming a protrusion, and the pin hole may be inserted into a discharge port of the mold die 17a, and then the pin hole may be fixed through the upper portion of the outer surface of the mold die 17a.

As described above, when a plurality of hole forming bars 27 are installed horizontally in the discharge port of the mold die 17a, the double synthetic resin panel extruded from the primary die 17 has a plurality of holes.

Step 5: Primary Sizing Step for Vacuum Forming

The extrudate of the double synthetic resin extrusion panel in which a plurality of holes are formed by the hole forming die provided at the mold die ejecting opening of the primary die is vacuum adsorbed from the primary sizing 21 to flatten and smooth the outer surface of the panel ).

The primary sizing 21 for vacuum molding is formed with a space such as a tunnel so that the synthetic resin double extrusion panel can be transported to the other side, and a plurality of vacuum holes are formed therein, and a synthetic resin double extrusion panel Adsorbed vacuum makes the outer surface smooth.

At this time, the primary sizing (21) for vacuum forming is made up of one unit, and the partition (22) is formed at 1/2 point internally so as to be divided into the primary vacuum 25 and the secondary vacuum 26 Respectively.

Since the double panel extruded from the primary dies 17 is just after the hole is removed from the hole forming bar 27, the primary sizing 21 weakens the vacuum pressure so that the surface vacuum is formed, The vacuum pressure is increased so that the hole and the overall shape are fixed.

Since the shape of the hole formed in the hole forming bar 27 is just after the hole is removed from the hole forming rod, the vacuum is only slightly applied to the surface of the primary vacuum 25, Vacuum is carried out globally in the vacuum chamber 26, and a plurality of holes passing through the inner body (A) of the panel are molded.

 That is, after the hole of the inner panel body to be extruded from the primary die 17 is formed into a circular shape from the beginning, the shape of the passing surface hole is not formed in the primary sizing 21 and is formed into a squashed circular shape, The elliptically shaped rod is arranged so that the larger diameter side is positioned on the vertical line, and is formed in a circular shape upon vacuum in the primary sizing (21).

In the present invention, when a new synthetic resin is used in the extrusion molding of a panel with a synthetic resin, holes formed therein are formed without being deformed at the time of extrusion. However, when using a waste synthetic resin, holes are formed, The shape of the hole is deformed. Therefore, in the case of the waste synthetic resin, the hole forming rod should be installed considering the round, square, rectangular, elliptical and other holes.

In the present invention, forming the partition 22 in the primary syringe 21 to divide the vacuum chamber into a first vacuum chamber 25 and a second vacuum chamber 26 forms a hole in the vacuum- However, since the extruding speed of the waste synthetic resin is slow, the vacuum pressure is firstly weakened in the first sizing 21 and the vacuum pressure is increased in the second vacuum 26, It can be done more quickly, which can increase productivity.

In addition, the primary siphon inlet has a wide front surface and a narrow rear surface so that the panel extrudate conveyed from the primary die can be easily introduced into the primary siphon 21, (C) is formed, so that the inflow of the extruded panel is easy.

  At this time, when the extruded panel extruded from the first die is fed into the first siphage, it must be pulled in a consolidated form when it is filled in the inlet, so that the panel is formed in a vacuum during the first sagging.

Since the primary discharger installed at the rear of the primary siphon is pulled in a consolidated form at the entrance of the primary siphon, the primary siphon is pulled in at the primary siphon entrance along the slope.

In the primary siphing, a pipeline is formed around the vacuum hole to circulate the refrigerant to cool the siphon.

Step 6: Primary vacuum cooling molding and water-cooling step

A primary vacuum cooler 30 is provided to fix the shape of the smooth extruded panel from the primary sizing 21 so that the shape of the extruded panel is cooled and prevented from being deformed during the cooling process.

 The primary vacuum cooler 30 is installed at the head of a water-cooling apparatus having a chamber shape to cool the double panel to be extruded and delivered by the primary sieving 21.

At this time, since the panel extrudate passes through the primary sizing, the external shape is formed by the double extruded panel, but since it is not completely cooled, it is completely cured by the primary vacuum cooler and the primary water cooling device, ≪ / RTI >

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 have a vacuum hole formed on the bottom surface, so that the synthetic resin double panel conveyed to one side does not interfere with movement, and adsorption and cooling are performed so that deformation does not occur during cooling.

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

As described above, the synthetic resin double panel, which is cooled while maintaining the flatness in the primary vacuum cooler 30, moves in a state of being immersed in water by a plurality of moving rollers installed in the primary water cooling unit 35.

At this time, when the primary water cooling device 35 is provided with a vibrator on one side of the water tank, the water is oscillated like a wave in the water tank, so that the cooling effect can be further enhanced.

In the present invention, a plurality of rollers are installed in a water tank of a primary water cooling device, and the synthetic resin double extrusion panel to be extruded is guided by the rollers, and water spray nozzles are installed at the upper and lower portions to spray water.

When the primary water cooling apparatus is filled with water and cooled, the primary vacuum cooler 30 and the primary water cooling apparatus 35 are installed with a partition so as not to interfere with the vacuum in the primary vacuum cooler installed at the tip, .

In this step, the synthetic resin duplex panel which has passed through the primary water cooling device 35 is formed into a complete panel by curing.

That is, since the panel that has passed through the cooling water is completely cooled and no further deformation occurs, there is no problem in using the panel as a state without being cut to a predetermined standard.

The panel that has passed through the primary water cooling device 35 is referred to as the primary extrusion panel 34 in the present invention.

Step 7: Dewatering and withdrawing of the outer surface of the panel

The water jetting on the surface of the first extrusion panel 34 which is water-cooled by the primary water cooling device is removed by the air jetting device 36. [

Since the surface of the primary extrusion panel cooled through the primary water cooling device 35 is in a wet state with water, it is necessary to dry the outside water for a subsequent process and dry it with the air injection device 36.

A first extractor 37 is provided on the same line on the rear side of the air injection device 36 so that the synthetic resin supplied from the first extruder 13 and the second extruder 14 passes through the first die 17, The primary vacuum chiller 30, the primary water cooling device 35, and the air injection device 36, as shown in Fig. At this time, the extrudate is discharged by the pressure output pushing from the primary extruder and the secondary extruder to the discharging portion of the primary die, and is moved by the pulling force pulled from the primary discharger after the primary siphoning.

Step 8: Preheating the primary extrusion panel in the heating chamber and forming the multilayer panel in the secondary die

The primary extrusion panel 34 pulled from the primary ejector 37 is drawn into the heating chamber 38 to dry the remaining moisture on the surface of the primary extrusion panel 34 and soften the surface.

The heating chamber 38 is provided in front of the secondary die 41 to heat the outer surface of the primary extrusion panel 34 drawn by the secondary die 41 so as to soften the primary extrusion panel 34, So that the resin is adhered well to the synthetic resin supplied from the third extruder 39 and the fourth extruder 40 in the car dies 41.

At this time, if the primary extrusion panel 34 is not softened in the heating chamber 38, the adhesive strength becomes weak when the secondary die 41 is laminated with the synthetic resin, resulting in a problem that the multilayered joint of the finished multilayered synthetic resin panel is worn The primary extrusion panel 34 must soften the surface in the heating chamber 38 device.

The primary extrusion panel 34 heated from the heating chamber 38 flows into the secondary die 41 and the waste synthetic resin fed 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 multilayer structure.

As described above, the panels stacked in the multi-layer structure in the secondary dies 41 are discharged from the secondary dies 41 and then transferred to the secondary sieves 42.

The third extruder 39 of this process is supplied with the raw material of the waste synthetic resin from the raw material mixing feeder installed on one side and is fed into the secondary die 41 by being fed in the third extruder 39.

The fourth extruder 40 is supplied with a raw material for synthetic resin from a raw material mixing feeder installed on one side and is melted in the fourth extruder 40 and injected into the second die 41.

The secondary die 41 does not need to form the hemispherical protrusion 20 like the inside extrusion of the primary die 17.

When the first extrusion panel 34 is inserted into the second die 41, the waste synthetic resin layer and the new synthetic resin layer are laminated and extruded on the outer surface thereof.

In addition, a synthetic resin inflow adjusting bolt is installed on the upper portion of the secondary die 41 so that the amount of waste synthetic resin and synthetic resin can be adjusted.

Step 9: Secondary Sizing Step

The secondary sizing 42 flattens and smoothly evacuates the extruded panel formed in the multi-layered structure in the secondary dies 41.

The secondary sizing 42 performed in this process smoothes the outer surface of the multilayer synthetic resin panel extruded from the secondary die 41 in a vacuum.

The secondary sizing 42 is constructed so that the multi-layer synthetic resin panel can be vacuumed at one time without being divided into the primary vacuum 25 and the secondary vacuum 26 like the primary sizing 21. [

The secondary sizing 42 also has an inclined surface such as "> " whose entrance is inwardly similar to the primary siding 21, so that the multi-layer synthetic resin panel extruded from the secondary die 41 can be easily inserted Respectively.

Step 10: Vacuum cooling and water cooling step

Therefore, the multi-layer synthetic resin panel transferred from the secondary sizing 42 is not completely cooled, but may be deformed during cooling.

The multi-layer synthetic resin extrusion panel that has passed through the secondary vacuum cooler 43 is cooled by precipitation cooling in water or water sprayed from a plurality of nozzles in the process of being guided and conveyed by the rollers in the same tank.

When the multi-layer synthetic resin extrusion panel is moved in a state where water is stored in the water tank of the secondary water cooling device 44, vibration is applied to the immersed water so that the water can be loosened.

Step 11: Drawing cooling and cutting and bending

The multi-layered synthetic resin extrusion panel is cooled in a secondary water cooling device 44, and then drawn out by a co-linear drawing-out cooling and molding machine and sent to a cutter.

The multi-layer synthetic resin extrusion panel drawn out of the drawing-out cooling and molding machine (45) comprises 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.

  In other words, the primary die 17 and the secondary die 41 of the present invention are discharged in a shape in which the discharge ports are convexly curved in the upper and lower portions, and then molded into precise shapes in respective sieves.

Explaining this in detail,

The raw material is not uniformly spread in the primary die 13 because the foamed layer is formed in the raw material due to gas while the raw material of the waste synthetic resin is injected into the die in the primary extruder 13

Therefore, in order for the product to spread well in the whole dice, the raw material should be spread well in the first dice as the dough is kneaded in the dice,

The strength becomes equal.

Because the raw material is a waste raw material, when the square product is formed in the dice, the product is foamed due to the gas, and when the product comes out from the first die, the product is folded like steamed bread and the product is folded. The product is inserted into the primary sizing 21 without raising the dice.

In order to make the holes 52 formed in the inner body of the primary extrusion panel 34 egg-shaped, a hole forming bar 27 is formed between the primary die 17 and the primary sizing 21, (52) is formed.

Further, in order to prevent the extrusion panel from being crushed like steamed bread and to prevent the plurality of holes 52 from being crushed, a new synthetic resin is laminated on the product one more time to form a rectangular shape, and the strength is formed and the flatness is smooth.

After that, the panel is made into square shape while the extrudate of the panel enters into the primary symmetry 21 and the primary cooling and vacuum is performed in the first vacuum chamber 25 with only a weak surface, so that the hole forming bar 27 A large number of holes C are formed without being adhered to the product and the hole forming bar 27 is pulled out so that the vacuum is gradually cooled and cooled at the first vacuum 25 and the vacuum is forced to be strong at the second vacuum 26 As the whole square is formed, the hole (C) and the foam layer of the product are formed, and the strength is strongly formed in the product.

12 is a cross-sectional view in which a plurality of hemispherical projections are formed in the interior of the primary die according to the present invention. After the waste synthetic resin material flowing in the primary extruder flows into the central portion feed path 18 of the primary die, And is introduced into the primary die 17 through the transfer path 18 which is formed as a single-

Since the waste synthetic resin is introduced into one conveying passage 18 and then divided into three pieces, the waste synthetic resin is in the form of a rice cake as in the state where the molten state is kneaded with the flour, so that the raw material is injected in one conveying passage The extrusion speed is lowered and the space is widened suddenly when it flows into the first die 17 from one narrow passage, so that the pressure output is applied only to the central portion and the extrusion speed is lowered at the both side portions.

In order to overcome such disadvantages, the present invention forms three divided passages (transfer paths) after being introduced into one passage (transfer path) to extrude the raw material of the waste synthetic resin in the first die 17 uniformly .

In addition, the primary die 17 of the present invention has a plurality of semi-spherical protrusions 20 formed on the upper, lower, left, and right inner surfaces so that the waste synthetic resin material rubs when extruded.
