Description

Granite apparatus for producing of controllable decorative pattern

Technical Field

The utility model relates to the field of granite production, in particular to a granite production device capable of controlling patterns.

Background

The agglomerated stone is an artificial stone which takes calcium carbonate sand, calcium carbonate powder and resin as main raw materials, and is produced in the form of square materials (common dimension: cuboid square materials with 2.7 meters long, 1.8 meters wide and 1-1.5 meters high), so the agglomerated stone is essentially different from the manufacturing process of single-piece production such as artificial quartz stone plates and the like.

The manufacturing process of the granite comprises the following steps:

1. unsaturated resin (added with a certain amount of accelerating agent and curing agent), sand and powder with different meshes and pigments with different proportions are used as raw materials, and the colors of the stirred lining are determined by the pigments with different types and proportions. Fully mixing the materials in one or more mixers, then feeding the materials into a main mixer, and manufacturing patterns with different thicknesses according to the mixing time (sometimes auxiliary means such as powder spraying and slurry spraying).

The granite equipment is stirred at a high place, and finally, a main stirrer (which is responsible for stirring patterns) is arranged, and the main stirrer is connected with a blanking chamber and a pressing chamber below the main stirrer, and can be sealed and vacuumized. The granite installation may comprise: the device comprises an empty die standby operation area (outside a blanking chamber), a blanking chamber, a main stirrer blanking port (top of the blanking chamber), a pressing chamber and a pressing square material discharging area (outside the pressing chamber). The main stirrer, the blanking chamber and the pressing chamber are internally provided with light and a camera, and the projection image is projected onto a screen, so that the operation of workers is facilitated.

2. The stock then falls under vacuum into a mold with an inner paper skin or release agent (drop height of about 2-3 m). A blanking frame with a wide upper part and a narrow lower part is arranged below a blanking port of the main stirrer, so that the materials can completely fall into the die. In the blanking process, a movable trolley carries a die with the length of 2-3 meters, the width of 1.6-1.8 meters and the height of 1.3-2 meters to reciprocate in a blanking chamber along a long shaft so as to ensure that blanking is uniformly and dispersedly fallen in the die.

3. After blanking, the movable trolley carries the die to the pressing chamber on the other side, the pressure head descends, and high-frequency high-pressure vibration is carried out under vacuum so as to ensure that square materials are compact and have no gap.

4. After pressing, the vacuum is released, the trolley carries the die to move out of the pressing chamber and is hung beside the pressing chamber, after the square stock is reacted and solidified, the screw of the die is loosened, the square stock is separated from the die and is clamped to one side by a special clamp.

5. After the square materials are placed for about one week, the square materials are turned by a plate turnover machine from the cross surface of the long shaft and the wide shaft to the cross surface of the long shaft and the height shaft to be upward, and the square materials are sent to a gang saw (vertical to the height shaft) to be cut into plates with preset thickness, which are called as rough plates.

6. Then the rough board is made into a smooth board through a polishing machine and a waxing machine, and then the smooth board can be packaged and sold.

In the plate manufactured in the way, dozens of tons of materials are scattered and fall in a lump in a few minutes, and due to the large falling head of the falling materials, the materials are scattered and fall, and the generated patterns are randomly generated and cannot form preset regular patterns like ceramic tiles and quartz pressed by single pieces. At present, different kinds of plates are made mainly by changing colors, but the shapes of patterns are not substantially changed.

The industry also improves the formula method:

according to the scheme I, the plate is made into a single-color plate, then the surface is printed and dyed with colors, and various patterns are made, so that the advantage is that the colors which can be made by spray painting can be realized on the plate surface, and the defects are that only one layer with a thin surface is used, and the surface patterns are slightly collided and processed, so that the surface patterns are damaged.

And secondly, adding a layer of belt between the stirring and blanking material and the die, stirring and blanking the stirring and blanking material on the belt, adding a roller for pressing the material on the belt, spraying slurry and dusting on the belt after pressing to form patterns, wherein the patterns are a little longer but still shorter because the material falls down less after pressing, and the patterns are still random and cannot form preset pattern shapes.

And thirdly, after the square materials are pressed once, digging out the square materials from the die in a lump shape, throwing the square materials into a stirrer, and stirring patterns in the main stirrer through spraying, dusting or mixing with auxiliary materials to obtain lump patterns with different sizes. The method is only suitable for making special ball-shaped patterns, and the patterns are still randomly generated.

The color in the production of the granite refers to titanium dioxide, iron oxide yellow, iron oxide black, iron oxide red, phthalocyanine green and the like, and one or more of the titanium dioxide, the iron oxide yellow, the iron oxide black, the iron oxide red, the phthalocyanine green and the like are prepared into the required color according to different proportions for use.

The color paste is high-fluidity paste ground by adding resin into titanium dioxide, iron oxide pigment and the like, and is sprayed on the surface of the paste when in use, namely the sprayed paste. The powder is prepared by uniformly mixing titanium dioxide, iron oxide pigment and the like to obtain the required color, and then spraying the mixture on the surface of the material, wherein patterns are formed due to the difference of the color of the mixture and the color of the material.

The granite is used for making patterns, and the calcium carbonate sand and the calcium carbonate powder used for the main material and the auxiliary material are the same and have different colors, so that the required pattern effect is formed. The number of the auxiliary stirrers is generally 4, and the color of the stirred materials in each auxiliary stirrer is different. The granite pattern is generated by mixing a main material with a certain color, auxiliary materials with different colors, powder spraying, slurry spraying and the like (which can be used independently or in combination) in a main mixer for several circles to form patterns with different colors.

Therefore, in summary, the prior granite square stock can only produce random and disordered short patterns or surface coating at the later stage, can not produce patterns with predetermined shapes of the whole body, can not produce regular patterns, can not produce stable long patterns, and has lower production quality and efficiency.

First class of embodiments

Reference is now made to fig. 1, which shows a schematic view of a device for producing controlled-pattern granite according to a first class of embodiments of the present invention.

As shown in fig. 1, the device 100 for producing controlled-pattern granite according to the first class of embodiments of the present invention comprises:

a stirrer 110 for stirring the raw material of granite into granite material;

a blanking chamber 120 located below the stirrer 110 and having a blanking port 121 formed between the blanking chamber and the stirrer 110;

a movable mould 130 able to enter the blanking chamber 120, so that the stirred agglomerated material can fall into the movable mould 130 along the blanking opening 121;

a pressing chamber 140 located at one side of the blanking chamber 120 and connected to the blanking chamber 120, and including a pressing device (not shown) for pressing the granite material in the movable mold 130 into a square material, wherein the blanking chamber 120 and the pressing chamber 140 can be closed together and vacuumized, so that the blanking and pressing operations are performed in vacuum;

a cutting device 150 for cutting the square stock taken out of the movable die 130 into a plurality of plate materials;

a polishing and waxing device 160 for polishing and waxing the plate;

any one or more of a plate 131, a surrounding frame and a pre-molded pattern material, which can be vertically placed in the movable mold 130 and have a preset horizontal sectional shape, wherein the plate 131 is coated with a pigment on the surface, the surrounding frame is formed by surrounding plates and injecting the pigment therebetween, a lifting device is arranged at the upper end of the plate 131 and/or the surrounding frame, and is used for moving the plate 131 and/or the surrounding frame out of the movable mold 130 after blanking is finished, and keeping the pigment in the granite material so as to form a preset pattern in the granite material, and the pattern material comprises one or more sections, and each section of the pattern material has a similar preset horizontal sectional shape and is staggered with each other.

In some embodiments, the lifting device comprises:

a plurality of vertical rods 134 fixed to the plate 131 and/or the enclosure;

a support 135 installed at an upper portion of the movable mold 130, the support 135 being provided with a plurality of holes at positions corresponding to the plurality of rods 134, the plurality of rods 134 penetrating into the plurality of holes, respectively;

a plurality of cords 136, one end of each cord 136 being secured to an end of one of the rods 134;

a lifting motor 137 fixed to the top inside the drop chamber 120, connected to the other ends of the plurality of ropes 136, for lifting the plurality of rods 134 through the plurality of ropes 136 to move the plate 131 and/or the enclosure out of the movable mold 130.

The plate 131 may be, for example, an iron plate, and may have a thickness of, for example, 3 mm. The number of said plates 131 and their preset horizontal section shape can be determined according to the desired granite through-body pattern.

The plurality of rods 134 may be, for example, screws, one end of which may be welded to the one or more plates 131 and the other end of which may pass through the bracket. The support 135 may be, for example, a support structure built on top of the movable mould 130 for fixing, together with the plurality of rods 134, the one or more plates 131, which act as a suspension for them to stand without falling. The plurality of cords 136 may be, for example, steel cords.

For example, in practical operation, 100 parts of unsaturated resin is firstly used, 3 parts of hydrogenated castor oil is added, the mixture is heated until the unsaturated resin is completely dissolved, equal amounts of calcium carbonate sand and calcium carbonate powder are added, and one or more colors with different proportions, such as required titanium dioxide, iron oxide yellow, iron oxide black, iron oxide red, phthalocyanine green and the like, are added, so that paste is prepared for later use.

Then, after a paper skin or a mold release agent was attached in the mold, a plurality of iron plates of a predetermined shape and a thickness of 3 mm were vertically placed in the movable mold. The lower end of each iron plate can contact the bottom of the mold, the upper end of each iron plate can be 30 cm lower than the top of the mold, a screw rod with the diameter of 3 cm and the length of 50 cm can be welded at the upper end of each iron plate at intervals of 70 cm (the screw rod is embedded and welded in the iron plate by 10 cm, and 40 cm is arranged above the iron plate), and at the moment, the screw rod is still 10 cm higher than the mold. The 10 cm channel steel is used on the die, the U-shaped support is built at a position 50 cm away from the four sides of the die (the number of the channel steel can be increased according to the position of the screw), the position of the channel steel corresponding to the screw is punched, the screw penetrates into the hole, and then the nut is screwed on, so that the suspension effect is achieved on the iron plate, and the iron plate is vertical and does not fall.

For example, a nut is screwed on the uppermost end of each screw, a lantern ring connected with a steel wire rope is arranged below the nut, and the inner diameter of the lantern ring is larger than that of the screw and smaller than that of the nut. Each steel wire rope is 18 mm in diameter and 8 m in length, one end of each steel wire rope is welded with a lantern ring, and the other end of each steel wire rope is connected with a lifting motor. The lifting motor is arranged on the top of the blanking chamber and is connected with the screw on the iron plate by a steel wire rope. The lifting motor can have 6 lifting motors, the power is 3Kw, and the left area of a blanking port of the blanking chamber can be increased to 5 meters, so that the lifting motor can be additionally arranged on the top of the blanking chamber.

For example, before the iron plate is lifted into the mold, the paste obtained above is coated on the place where the coarse pattern is needed on the iron plate, and if the fine pattern is needed, the color paste (the color paste obtained by grinding resin and titanium dioxide, iron oxide pigment and the like) and the color powder (the color powder obtained by uniformly mixing titanium dioxide, iron oxide pigment and the like) are sprayed on the iron plate.

Then, the iron plate is hung in a die and connected with a steel wire rope. Then the small vehicle-mounted mould enters a blanking chamber, after the main stirrer stirs the materials, the small vehicle-mounted mould reciprocates left and right in a vacuum state, and the main stirrer opens a blanking door and blanks the materials into the mould provided with a plurality of iron plates with preset shapes. After blanking, the trolley-mounted mould moves to the position below a lifting motor of the blanking chamber, the lifting motor pulls a steel wire rope to enable the iron plate to rise to be completely separated from the mould, and paste and color paste with colors on the iron plate can be remained in materials under the extrusion force and the viscous force of tens of tons of materials. Because the shape of the iron plate is designed in advance, the pattern in the obtained material is basically the preset pattern.

For example, the material in the die is drawn into a pressing chamber for pressing and forming, placed in vacuum, taken out of a press, placed for a week, turned over 90 degrees until the intersection of the long axis and the height axis faces upwards, cut into rough boards perpendicular to the height axis and polished. And the iron plate is transported out of the blanking chamber by a trolley, and the paste and the color paste are coated again for next use.

In other embodiments, a single piece of iron plate may be replaced with a surround. For example, the enclosure frame, that is, the enclosure frame formed by two parallel (or non-parallel) iron plates and having an open top and a closed periphery, may be configured according to the requirement. Further, fine openings can be cut in a scattered manner from top to bottom every 50 cm around the enclosure frame (without damaging the strength of the iron plate), so that the internal air can be extracted during vacuum pumping. Then one or more materials (such as titanium dioxide, iron oxide and other pigments prepared according to the requirements, calcium carbonate sand, calcium carbonate powder, unsaturated resin, accelerator, curing agent and the like which are mixed and stirred) with required colors and are mixed with different colors are poured into the surrounding frame, and very wide patterns can be made. The number and shape of the patterns are preset according to the iron plates and/or the surrounding frame. The enclosure frame and the iron plate can be used independently or combined together. Then, the same as the iron plate process: entering a blanking chamber, blanking by a main stirrer, pulling out an iron plate and an enclosure frame, pressing and the like.

In some embodiments, special materials, such as optical fiber (transparent strip), can be added, and the special materials are arranged in a preset shape to be hung on a plastic lifting rope, a steel wire rope and a lifting motor are not connected, the plastic lifting rope is hung above the interior of the mold, the outer edge of the lifting rope is pulled by the plastic rope and wound on an anchor rod outside the mold, and the plastic lifting rope is ensured not to fall down. After the main stirrer drops to the mould, the trolley directly carries the mould to the pressing chamber for pressing, and the plastic rope and the hung optical fiber are pressed into the material together. After the material is solidified and cut, the slab with the plastic lifting rope is discarded, and the lower edge of the slab is a plate with preset patterns and special materials, for example, optical fiber can form a light-transmitting small hole with a special shape.

In still other embodiments, the mold can be made by silica gel, two (or more) sections of molds are made, the shape (in top view) of the required pattern in the middle is made, the total height of the two sections of molds is equal to the height of the square stock to be pressed, the patterns on the upper and lower sections of the molds are consistent, but the upper and lower sections of the molds can be staggered in the vertical position (when the molds are pressed by a press, the patterns are crushed and the risk is avoided after the patterns are staggered), then calcium carbonate sand, calcium carbonate powder and resin are made into slurry with good fluidity (the slurry can be single color or multiple color, even a part of the slurry is main material color, so the effect of the main material and the patterns can be obtained by the blending effect), the slurry is poured into the silica gel under vacuum, after the pouring material is solidified and demoulded, the patterns in the silica gel are vertically placed into the mold carried by a trolley, the lower end of the lower section is close to the molds, and the lower end and the upper end of the upper section are on a horizontal plane, lower section and upper segment decorative pattern material are all fixed with a rope (the lifting machine holds the one end of rope, and the rope passes the round hole that the decorative pattern material top was beaten 20 centimeters downwards, and the other end is on a couple at top, connects a motor behind the couple, wait the blanking to decorative pattern material can stabilize the back of standing, the motor rotates and drives the couple and rotate, the couple turns to the angle that can not hang the rope, then the rope breaks away from the couple to deviate from in the trompil of decorative pattern material). The pattern material is pulled by a steel wire rope and is hung in a mould carried by a trolley, and the other end of the steel wire rope is arranged on a lifting motor at the top of the blanking chamber. After the main stirrer finishes dropping the material to the mold, the steel wire rope is pulled out, only the residual pattern material is buried by the main material in the mold, and the trolley-mounted mold is opened to a pressing chamber for pressing.

Reference is now made to fig. 2, which shows a front view, a horizontal section view and a schematic illustration of the pattern of the produced panel of assembled movable moulds, according to a first class of embodiments of the utility model, wherein the upper left is a front view of the movable moulds, the lower left is a horizontal section view of the movable moulds and the lower right is a schematic illustration of the pattern of the produced panel.

the lifting means 412 is used to lift the upper and lower ports of the funnel 410, respectively, such that when the movable mold 130 is reciprocally moved such that the upper port of the funnel 410 is adjacent to one end of the movable mold 130, the lower port of the funnel 410 is also adjacent to the one end of the movable mold 130.

2 lifting devices 412 are installed on the left and right sides of the blanking port 121, the lifting devices 412 are lifting motors, for example, the lifting motors are connected with a plurality of ropes 411, the ropes 411 are steel wire ropes, for example, and a funnel 410 is hung below the steel wire ropes. The steel cord may be 4 or more, for example.

The upper right portion of fig. 3 is a top view of the funnel 410. As shown in the figure, the funnel 410 is wide at the top and narrow at the bottom, and both the top and bottom are rectangular, for example. The dimensions of the funnel 410 are for example: the upper opening is 1.7 meters long and 1.2 meters wide, the lower opening is 1.7 meters long and 0.25 meters wide, and the height of the funnel is 0.6 meters. For example, four lifting lugs are arranged at four corners of the upper opening of the funnel 410, two lifting lugs are arranged on the wide side of the lower opening of the funnel, and each lifting lug can be hung with a steel wire rope and lifted by a lifting motor.

The mixer 410 can mix patterns according to the existing technology, that is, the main mixer mixes a main material with one color, the auxiliary mixer mixes auxiliary materials with different colors, or sprays color paste with different colors and scatters toner with different colors (the three are three independent technologies, which can be used separately or in combination), and then the auxiliary materials are fed into the main mixer through a belt to be mixed for several circles. Different from the prior art, the resin is added by a little, for example, 3-5 percent, so that the material has better fluidity, and then the material is vacuumized and blanked. It would have been constrained by the drop opening 121 and dropped directly into the mold 130, now into the funnel 410. And operating the lifting motor to keep the distance between the lower opening of the funnel 410 and the material surface at 20-30 cm. At this time, the cart still carries the mold 130 to reciprocate left and right along the long side axis, and the long side of the funnel 410 is vertical to the long side of the mold in the horizontal direction. As the level rises, the hopper 410 also rises, maintaining a distance from the level. When the upper opening of the funnel 410 is close to and contacts with the wide side of one side of the mold 130, the lower opening of the funnel 410 is also close to and contacts with the wide side of the mold 130 on the same side by the lifting motor which hangs the steel wire rope at the lower opening of the funnel 410. When the trolley runs in the other direction, the steel wire rope is lengthened by the hoisting motor which is dragged before, the steel wire rope on the other side is slowly tightened, and the frequency converter is adjusted to match the speed of the steel wire rope, so that the upper opening and the lower opening on the same side of the funnel 410 are close to and contact with the wide edge of the same side mold 130 at the same time. Therefore, the lower opening of the funnel 410 is close to the wide edges at two sides of the die 130, and the phenomenon that patterns at the end part are bent due to insufficient blanking at the wide edges at two sides of the die is avoided. After the material in the blender 110 is discharged, the funnel 410 is lifted to the upper side of the mold 130 until the material of the funnel 410 is almost dropped. The mold 130 is loaded by the trolley and opened to the pressing chamber 140 for pressing and forming, and then is solidified and demoulded. After one week, cutting a rough plate by taking the cross surface of the long shaft and the wide shaft as an upward surface and being vertical to the wide shaft; alternatively, the batt is cut perpendicular to the height axis by turning it over until the major axis and height axis cross upward, as in the prior art. The finished board is then finished, i.e. formed with long through-grain or hill-lines, which are substantially parallel to the long sides of the board.

Different from the prior art that the granite material falls randomly, the granite material falls into the funnel 410 and flows out from the lower opening under the dead weight, the patterns are forcibly stretched and tiled in one direction, and the out patterns are parallel lines with full length. If the funnel material is not uniformly dropped, the place with much material is pressed down to be the mountain line. The density of the patterns can be controlled to obtain dense patterns which are orderly parallel or sparse long patterns. That is, by mixing the primary and secondary materials (or gunite or dusting) in different colors in a blender and flowing down a "funnel" during the blanking process, the patterns are made to be uniform, thereby forming long and continuous patterns. Therefore, the number of the patterns can be controlled by controlling the proportion of the main material to the auxiliary material, the guniting and the dusting, the thickness and the distribution density of the patterns can be controlled by controlling the time for stirring the patterns by the main stirrer, and the materials can be controlled not to be disconnected by controlling the moving speed and the blanking speed of the trolley to be matched, so that the continuity of the patterns is realized, and the density of the patterns can be controlled to a certain degree.

The funnel 410 may be coated with a release agent prior to use and knocked off after the material remaining on the funnel 410 has cured.

The controlled pattern granite manufacturing apparatus 400 according to the second type of embodiment of the present invention has been described above with reference to the accompanying drawings, it being noted that the above description and the drawings are only examples and are not intended to limit the present invention. In other embodiments of the utility model, the apparatus may have more, fewer, or different components, and the connections, inclusion, and functional relationships between the components may differ from those described and illustrated. For example, typically a component will contain sub-components in addition to those shown and described; multiple components may be combined into a single larger component, and so on. For example, the device may comprise, in addition to the components described and illustrated above, other conventional components used in the production of granite, as known to the person skilled in the art, such as those mentioned in the background section of the present description. For example, the mixer 110 may include a main mixer and several sub-mixers, and may further include a guniting and scattering device, etc. All such variations are within the spirit and scope of the present invention.

Fig. 4 shows an example of a granite pattern produced using a controlled pattern granite production apparatus according to a second class of embodiments of the present invention.

According to the granite production device with the controllable patterns, which is disclosed by the second class of embodiments of the utility model, the blanking mode is changed from dropping to flowing out through the funnel, so that the defect that only random, disordered, short and surface patterns can be made in the prior art is overcome, long patterns or mountain patterns of the whole body can be made, and the thickness and the density of the patterns can be adjusted; and because the decorative pattern has regularity, through piecing together two blocks of panels, can obtain the pattern that has special effect. In addition, because the patterns are formed in the die instead of the stirrer, compared with the prior art, a great deal of time can be saved, and the production efficiency and the quality are improved.

Class III examples

Reference is now made to figure 5, which shows a schematic view of a device for producing controlled-pattern granite according to a third class of embodiments of the present invention.

As shown in fig. 5, a controlled pattern granite production apparatus 700 according to a third class of embodiments of the present invention comprises:

a stirrer 110 for stirring the raw material of granite into granite material;

a blanking chamber 120 which is positioned below the stirrer 110 and is provided with a blanking port between the blanking chamber and the stirrer;

a movable mould 130 able to enter the blanking chamber 120, so that the stirred agglomerated material can fall into the movable mould 130 along the blanking opening 121;

a pressing chamber 140 located at one side of the blanking chamber 120 and connected to the blanking chamber 120, and including a pressing device for pressing the granite material in the movable mold 130 into square material, wherein the blanking chamber 120 and the pressing chamber 140 can be closed together and vacuumized, so that the blanking and pressing operations are performed in vacuum;

a cutting device 150 (not shown in fig. 5) for cutting the square stock taken out of the movable die 130 into a plurality of plate materials;

a polishing and waxing device 160 (not shown in fig. 5) for polishing and waxing the plate material; and

any one or more of the gunning device 711, the dusting device 712, and the sub-mixer 713, wherein,

the guniting device 711 is used for spraying color paste on the surface of a layer of granite falling into the movable mould 130;

the dusting device 712 is used for dusting the powder on the surface of the layer of granite falling into the movable mold 130;

the sub-blender 713 is used to drop the sub-ingredients in the movable mold 130.

In some embodiments, the granite production apparatus 700 further comprises: a crusher 714 for crushing the granite material from the blanking chamber 110 and dropping it into the movable mold 130. The granite material from the mixer 110 is sized and crushed into uniform sizes by the crusher 714, and then special patterns are obtained by dusting, guniting, etc. The crusher 714 may force the granite material through the mesh and break it into smaller pieces. The pieces are then separated by a sub-mix or guniting powder, which can form a finely divided pattern.

The guniting device 711, the powdering device 712 and the secondary mixer 713 may be similar to the corresponding devices in the prior art, and unlike the prior art, the guniting device 711, the powdering device 712 and the secondary mixer 713 of the present invention operate in the drop chamber 120, and directly guniting, powdering and dropping the secondary material in the mold 130, rather than operating in the main mixer 110.

For example, 4 guniting heads (2 each on the left and right of a blanking door) can be added below a blanking port of the main mixer 110, a pneumatic switch is connected behind the guniting heads, a 4-minute plastic hose is connected behind the pneumatic switch, the plastic hose is connected to a conical hopper outside a blanking chamber, the diameter of the conical hopper is 50 cm, the height of the conical hopper is 80 cm, the lower part of the conical hopper is connected with the 4-minute hose through a quick connector, the upper part of the conical hopper is sealed, only one 1-inch switch is welded to be communicated with the outside, the switch is opened, color paste with pre-prepared colors (the color paste can be prepared by respectively adding resin into titanium dioxide, iron oxide pigment and the like and grinding the color paste into respective paste, the color paste can be prepared according to different proportions when the color is used), and the switch is closed to isolate the vacuum.

The main mixer 110 mixes the materials and vacuumizes them according to the usual process. During blanking, when the amount and distribution of the materials falling into the die 130 are properly controlled, the blanking port is closed, blanking is suspended, the pneumatic switch is started, the slurry spraying head sprays slurry, the length and distribution of patterns are determined by controlling the slurry spraying range, and then slurry spraying is closed to continue blanking. Repeating the steps until the blanking is finished.

Then, the mold 130 is loaded on the cart to the pressing chamber 140 to press, vacuum, release the mold, cut the blank plate with the long axis and the wide axis crossing upward perpendicularly to the wide axis, or turned over 90 degrees, cut the blank plate with the long axis and the height axis perpendicularly to the height axis, and finished into a finished plate.

The board produced by the method can have long and continuous 'mountain ridges' because the slurry does not move after the slurry is sprayed, and can also be intermittent cracks or block-shaped lines with different lengths.

For another example, an auxiliary mixer 713 may be disposed next to the main mixer 110, the auxiliary mixer 713 being coupled to the upper portion of the drop chamber 120 as with the main mixer 110. There may be another 4 auxiliary agitators with belts respectively leading to the main agitator 110 and the adjacent auxiliary agitator 713, and patterns can be first stirred in the main agitator 110 and the auxiliary agitator 713 before the next step of blanking is performed according to the required effect. When the vacuum pumping is performed for blanking, the main stirrer 110 falls to a certain degree to close the blanking door, and the auxiliary stirrer 713 discharges the material. The thickness of the pattern can be controlled by controlling the fluidity of the auxiliary material in the auxiliary mixer 713, and the pattern distribution can be controlled by controlling the blanking distribution of the auxiliary mixer 713. The auxiliary material in the auxiliary mixer 713 and the main material in the main mixer 110 are uniformly mixed by calcium carbonate sand, calcium carbonate powder, unsaturated resin, accelerator and curing agent, and visible patterns can be formed only if the colors are different. And (3) closing the blanking door when the auxiliary stirrer blanks to a certain degree, and replacing the main stirrer to blank (the main stirring blanking controls the pattern shape), and repeating the steps until the blanking is finished. Generally, the main materials are more and harder, so that the main materials are not deformed after being formed into a certain shape, the blanking is suspended after a part of the main materials are blanked, and the main materials can be flat, can be more on one side and less on one side, and can also be fluctuated like mountains. The auxiliary material falls on the main material, the auxiliary material is softer, and flows to the main material to form the main material after falling, the auxiliary material does not cover the main material, so that patterns are formed at the position where the auxiliary material falls, and the distribution of the patterns is controlled by the auxiliary material.

Furthermore, guniting and/or dusting may also be used. The auxiliary material dropping, the guniting and the dusting are independent processes and can be used independently or together.

The patterns obtained by spraying and dusting are fine, and the auxiliary material falling from the auxiliary stirrer can form coarse patterns. Preferably, some main materials (or materials with the color close to that of the main materials) are added into the auxiliary materials to be stirred, and then the auxiliary materials and the main materials are alternately blanked, so that the phenomenon that the auxiliary materials are stiff is avoided. According to different distribution of the main material and the auxiliary material, the patterns are different in density and shape. The auxiliary material is a single auxiliary material, the guniting is added, and a plurality of auxiliary materials are uniformly stirred and then are blanked.

The said guniting, dusting and powder-dropping can be alternatively carried out with the main material-dropping, i.e. several main materials are piled up in the mould and then the auxiliary material or guniting and powder-dropping are carried out, so that the formed pattern is larger. Or the guniting, the dusting and the auxiliary material falling can be carried out simultaneously with the main material falling, so that the formed patterns are scattered and broken.

The controllable pattern granite manufacturing apparatus 700 according to the third type of embodiment of the present invention has been described above with reference to the accompanying drawings, it being noted that the above description and drawings are only examples and are not intended to limit the present invention. In other embodiments of the utility model, the apparatus may have more, fewer, or different components, and the connections, inclusion, and functional relationships between the components may differ from those described and illustrated. For example, typically a component will contain sub-components in addition to those shown and described; multiple components may be combined into a single larger component, and so on. For example, the device may comprise, in addition to the components described and illustrated above, other conventional components used in the production of granite, as known to the person skilled in the art, such as those mentioned in the background section of the present description. For example, the blender 110 may include a main blender and a plurality of sub-blenders, and the like. All such variations are within the spirit and scope of the present invention.

Fig. 6 shows an example of a granite pattern produced using a granite production apparatus with controlled pattern according to a third class of embodiments of the utility model, in which the left side shows the agglomerate-like pattern formed by falling charge and the right side shows the agglomerate-like pattern with a clearer border formed by guniting and dusting.

According to the granite production device with controllable patterns of the third class of embodiments of the utility model, the auxiliary material is directly dropped or the gunite is sprayed and powdered into the mould to make the patterns, the mould is internally sprayed with the layered gunite and paved with the layered materials, so that the defect that the traditional method can only make random, disordered, short and superficial patterns is overcome, the natural-imitated patterns which are well-arranged and can not be made by the common method, such as special patterns like block-shaped patterns, can be obtained, the particle board which can only be made with short broken patterns in the past can also be made with long patterns, is not influenced by the formula, and the pattern, the distribution, the thickness and the density of the patterns can be conveniently adjusted; and because the decorative pattern has regularity, through piecing together two blocks of panels, can obtain the pattern that has special effect. In addition, because the patterns are formed in the die instead of the stirrer, a great deal of time can be saved compared with the original method, and the production efficiency and the quality are improved.

Although the present invention has been disclosed above by way of examples, the present invention is not limited thereto. Various changes and modifications within the spirit and scope of the utility model will become apparent to those skilled in the art from this disclosure, and the scope of the utility model should be determined only by the language of the claims and the equivalents thereof.
