It is possible to manufacture the plate through hardening after additionally pressing smoothly through it, and it is possible to continuously form artificial stone internal and external plate with uniform thickness without any variation. Cement as a raw material through vibration compaction method It is possible to reduce the rate of water addition in mortar and to continuously produce in the longitudinal direction on the workbench without a separate molding mold, so that it is possible to cut the required size before complete curing by shortening the curing time of mortar. Convenience can maximize work efficiency, and it is possible to manufacture plate of various specifications, and to shorten plate manufacturing time and improve productivity.

In general, the artificial stone plate is manufactured by curing the powdered stone powder made of a mixture of stone powder made of alumina hydroxide, dolomite, silica sand, viscous polymer resin liquid, and chips made of synthetic resin particles into a mold. Widely used for building interior materials, furniture and crafts.

Artificial stone plate has the advantages of simple processing and installation compared to the existing tiles, and has the advantage that can be produced to have a variety of patterns and colors, resistant to heat and moisture compared to wood.

In addition, while having a surface texture similar to expensive marble or granite, it can be produced at a very low price, it is widely used in various fields.

The method of manufacturing such artificial stone plate is as follows.

That is, in the prior art, as shown in the patent registration No. 10-0221467 "artificial stone plate and its manufacturing method" by pouring the stone powder batter liquid as described above in the mold formed with artificial stone plate forming space so that the artificial stone plate is formed side by side with respect to the ground and hardened The artificial stone plate was produced.

As described above, in the case of manufacturing artificial stone plate using a mold formed in a state in which the artificial stone plate is arranged side by side with respect to the ground, it requires a work space equal to the area of the mold, and in order to manufacture a large number of artificial stone plates at the same time. Since more work space is required, there is a problem in that the production cost increases because a factory having a large area is required to manufacture artificial stone plate.

Considering these problems, it is possible to mass-produce artificial stone plates even in a relatively small working space, and it is possible to produce artificial stone plates without deterioration in quality even if the artificial stone plates are made of stone powder batter made of polymer resin liquid which is relatively inexpensive and has high shrinkage. It can be manufactured, so that the artificial stone plate to prevent the bending phenomenon occurs to produce a thin artificial stone plate is known in the Republic of Korea Patent No. 10-0795986 "artificial plate manufacturing apparatus and method", the composition is "polymer resin solution and stone powder An artificial stone plate manufacturing apparatus for manufacturing a plate-shaped artificial stone plate by pouring the mixed stone powder batter liquid into a mold, comprising: a rectangular box-shaped outer frame having an open top surface; placed on an inner bottom of the outer frame and extending left and right on an upper surface thereof A bottom frame member having a plurality of bottom grooves formed side by side; Two side frame members vertically oriented vertically with respect to the bottom frame member so as to be in contact with both side surfaces of the side, and having a plurality of vertical grooves extending up and down side by side; It is to include a plurality of diaphragm to be inserted into the groove, the stone powder batter liquid is filled therebetween so that the artificial stone plate is molded.

In addition, by inserting the kneaded paste into the molding die and compressing it using a roller, continuous production is possible, and the roller is molded to be pressed only to a certain degree while being prevented from being randomly separated from the molding die. By maintaining a uniform strength and as well as ensuring continuous productivity, the cost reduction is possible "patent manufacturing device of artificial stone excellent strength with the same thickness" of the Patent Publication No. 10-2009-0100064, the structure is known "The worktable is formed with rails on both sides to form the inner space, the pressure roller for pressing the kneaded paste filled in the inner space of the workbench, the guide roller for being seated on the rail to both sides of the pressure roller is pressed The inner diameter is smaller than the roller, so the pressurized roller It is known that "an apparatus for producing artificial stone excellent in strength at the same thickness by pressurizing a paste to be pressed into a certain thickness and continuously produced while being incorporated therein is known.

In addition, in order to ensure that the raw material is evenly accommodated in the molding mold, the moisture content ratio must be increased in the case of cement mortar. Therefore, it takes a lot of time to dry harden the slabs, which lowers the productivity and evaporates the moisture during curing. There is a problem that the deformation of.

And the roller compression molding method of the "apparatus for manufacturing artificial stone with high strength at the same thickness" of the Patent Publication No. 10-2009-0100064 also includes a rail having an inner space so that the paste is accommodated, so that the size of the slab is the rail as in the former case. There is a problem that is dependent on the specification of.

In the case of cement mortar, the moisture content is slightly smaller than the former mold molding, but there is a problem that deformation is caused during the curing process due to the difference in density between the upper surface of the product on which the roller compressive force is applied and the lower surface where the roller does not contact.

Therefore, an object of the present invention is to solve the problems as described above, it is possible to continuously mold the artificial stone interior and exterior plate material with a uniform thickness without variation to minimize deformation through uniformity of density, vibration compaction method By reducing the W / C ratio (water / cement ratio) in the raw material cement mortar as well as applying a continuous production in the longitudinal direction on the workbench without a separate molding mold, by reducing the hardening time of the mortar It is possible to cut to the required size before hardening so that the work efficiency can be maximized by the convenience of standard cutting work, and it is possible to manufacture plate of various specifications, and it is possible to shorten plate manufacturing time and improve productivity. It is for providing a manufacturing system.

The present invention for achieving the above object by using a raw material input and propulsion means intermittently reciprocating through the drive means to be transported to the vibration compaction means by a predetermined amount of plate material discharged onto the work table through the hopper Characterized in that the plate can be manufactured by additionally pressing the upper surface of the flat plate through the flat means in a state that the raw material transferred through the vibration compacting means is compacted into a high density flat plate having a certain width and thickness. do.

As described above, the artificial stone internal / exterior plate manufacturing system of the present invention does not use a molding mold, and moves straight on the workbench, thereby making it possible to carry out a series of flattening operations such as split supply of raw materials, vibration, and flattening as a finishing process. It is possible to continuously form the artificial stone inner and outer plates of one thickness, and the density of the plates is uniform, so that the product can be advanced by minimizing deformation.

In addition, since it is a method of forming into a flat plate while hitting and pressing by vibrating compaction method, the W / C ratio of cement mortar, which is a raw material, can be drastically reduced to shorten the curing time, and continuous in the longitudinal direction on the work table without a separate molding mold. It is possible to cut to the required size before the mortar is completely hardened, so the work efficiency can be maximized by the convenience of standard cutting work, plate production of various specifications is possible, plate production time is shortened and productivity is improved. It is to have an effect that can be.

In the apparatus of the present invention, as shown in FIG. 5, the linear induction means 20 of the frame 10 is coupled to the rail 21 fixed on the work table T, so that the linear movement is possible.

In this state, the driving means 30 is operated, and then raw materials of artificial stone and exterior plate materials are introduced into the hopper 41. At this time, the raw materials are mortar in which cement, sand and water are mixed. When the input weight is 100, the weight is 15 to 25% by weight.

When the driving means 30 is operated, the reduction gear 32 is operated by the rotation of the motor 31, and the cam plate 33 of the reduction gear 32 has an operating rod 64 connected thereto through the eccentric shaft 61. The reciprocating motion is to push the raw material introduced into the hopper 41 to the vibration compacting means 50. This will be described in more detail as follows.

When the eccentric shaft 61 and the raw material input plate 62 are retracted as much as possible as shown in FIG. 6 as the cam plate 33 rotates, the outlet 41 'of the hopper 41 is opened to the maximum for smooth discharge of the raw materials. At this time, the intermittent control structure 91 is rotated counterclockwise as shown in FIG. As the raw material in 41 is stirred, it is discharged uniformly on the work table T.

In this state, when the eccentric shaft 61 and the raw material input plate 62 are advanced as shown in FIG. 7 as the cam plate 33 rotates, the intermittent control structure 91 is clockwise as shown in FIG. 9. It is rotated so that the ratchet 91D rides over the ratchet wheel 91A and is idling to prevent the dispensing shaft 42 from rotating. The raw material input plate 62 which is advanced has a large portion of the outlet 41 'of the hopper 41. It is blocked and the tip plate 63 of the tip is to transport the discharged raw material to the lower portion of the vibration compaction plate 53 of the vibration compaction means (50).

When the raw material input plate 62 pushes the raw materials as described above, the external force is generated in the opposite direction of the pushing direction to the frame 10 due to the friction force between the raw material and the work table T. In this case, the guide roller 23 fixed to the frame 10 is secured by moving straight along the rail 21 fixed on the work table T, and the vibration compaction plate 53 also moves forward. Quickly contact with raw materials.

On the other hand, the raw material introduced into the vibration compacting means 50 is to be compacted at a high density through the vibration compaction plate 53 which generates 4000 to 6000 vibrations per minute through the high frequency vibrator 52, The inlet side of the vibration compaction plate 53 is configured to be inclined slightly higher than the outlet side for smooth inflow of raw materials, and its inclination is appropriately set to about 0.5 to 1 °, and the outlet side end of the vibration compaction plate 53 is appropriate. The height of is to be 3 to 5㎜ lower than the thickness of the artificial stone and the inner plate manufactured.

The vibration compacting plate 53 is made of abrasion-resistant steel, the bottom contacting the raw material is polished to minimize friction, and the end of the bottom side of the outlet side is rounded to minimize the pressing marks.

On the other hand, the distance between the vibration compaction plate 53 and the work table T can be adjusted according to the user's needs. As shown in FIG. 4, when the pressure adjusting member 57 is inserted under the rear pressure spring 55, the support 51 The rear side of the lower side can be relatively lowered to incline the vibration compaction plate 53. If the pressure adjusting member 57 is inserted under all the pressure springs 55, only the height of the vibration compaction plate 53 is provided without the inclination. The height can be adjusted according to the height of the pressure adjusting member 57 to be lowered.

On the other hand, the raw material compacted in the flat plate shape in the vibration compaction means 50 is the top surface of the flat plate where the compaction is completed, the vibration compaction plate 53 is inclined in the width direction at regular intervals at a predetermined interval so that the upper surface There is a need for an additional process to smoothly finish.

When the flat means 70 is moved immediately by the above-mentioned reversal movement of the frame 10, the flat material chopped by the vibration compaction means 50 is located under the flat press plate 77, and the flat press plate 77 ) Is lifted up as shown in FIG. 7 to prevent friction with the raw material.

In this state, when the eccentric shaft 61 and the raw material input plate 62, which were advanced according to the rotation of the cam plate 33, are retracted, the raw material input plate 62 connected to the operation rod 64 is backward as mentioned. The dispensing shaft 42 evenly distributes the raw material in the hopper 41 by opening the discharge port 4 'of the hopper 41 and rotating the ratchet 91D of the intermittent control structure 91 by rotating the ratchet wheel 91A. While squeezing and being discharged on the work table T, the connecting rod 79 connected to the actuating rod 64 is pulled back as shown in FIG. 6 while the connecting rod 73 and the sprocket wheel 71 are pulled clockwise to be connected thereto. The chain 75, the support rod 76, and the flat pressing plate 77 are lowered due to the elastic force of the pressure spring 78, and the flat pressing plate 77 is lowered by additionally pressing down the surface of the compacted raw material. It is smoothing.

As the raw material on the flat plate after the flat work as described above is significantly reduced compared to the conventional method, the density and hardness are high, so that the cutting process is possible immediately. Used as

Meanwhile, the thickness of the raw material flowing into the vibration compacting means 50 may be adjusted according to a user's necessity. As shown in FIG. 11, the height adjusting bolt 81 is removed in a state where the adjusting plate fixing bolt 85 is loosened. After adjusting the height of the adjusting plate 83 by adjusting and tightening the adjusting plate fixing bolt 85 again, the gap between the worktable T and the adjusting plate 83 through which raw materials pass can be adjusted, and the adjusting plate 83 is wear-resistant. It is good to make an inclined surface inside to make this strong steel and to smooth the passage of raw materials.

In the present invention as described above, when the raw material input plate 62 is advanced to push the raw material to the vibration compacting means 50, the frame 10 is advanced and at the same time the distribution shaft 42 is stopped to temporarily distribute the raw material. When the raw material input plate 62 is retracted, the frame 10 is stopped and the distribution shaft 42 is rotated to discharge the raw material onto the work table T. In addition, the flat pressing plate 77 is a process of flattening the flat surface of the raw material is lowered and compacted is repeated.

In the above, one embodiment of the present invention has been described, but modifications and variations within the scope without departing from the technical spirit of the present invention by those skilled in the art belong to the scope of the present invention Of course.
