Description

Technical Field

[0001] This application relates to the field of slab production technology, and in particular to an inorganic artificial stone slab production system and its production process. Background Technology

[0002] Currently, wall panels are commonly used in wall renovation and decoration. There are many types of wall panels, such as plywood, fiberboard, and inorganic panels, among which inorganic panels are the most popular because they offer fire resistance, moisture resistance, sound insulation, heat insulation, impact resistance, and aging resistance. Inorganic panels are a type of artificial stone slab, a new type of stone developed from traditional artificial stone slabs. They are mainly made from inorganic binders, powders, aggregates, and other raw materials. Due to the characteristics of inorganic artificial stone slabs, their production requires specialized machinery and equipment, along with specific processes and workflows.

[0003] Traditional methods for producing inorganic boards include the block-type preparation method and the plate-type preparation method. The current plate-type preparation process involves raw material preparation, mixing, material distribution, pressing, curing, grinding and polishing, further processing, and inspection.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] Previous production systems had low levels of automation and unreasonable overall design, which affected the product quality of inorganic artificial stone slabs, as detailed below:

[0006] In the powder supply and conveying stage, the powder used to be homogenized by single-stage and single-bar homogenizers, which could not meet the full homogenization effect of various powders.

[0007] In the supply stage of additives, additives used to be measured and stirred manually. Manual operation inevitably leads to problems such as measurement errors and uneven stirring.

[0008] For example, in the mixing stage of a mixer, traditional mixers only use a single mixing rod to mix powders, which not only has low mixing efficiency but also unsatisfactory mixing effect;

[0009] For example, in the material feeding stage of the target mixture, there was previously a lack of a process to further quantify and homogenize the target mixture before feeding, which could easily lead to problems in the subsequent blank production. Also, before the material feeding mold enters the feeding conveyor belt, paper is usually laid on the conveyor belt to solve the adhesion between the target mixture and the feeding conveyor belt. However, laying ordinary paper on the feeding conveyor belt can easily cause wrinkles in the paper, which in turn affects the thickness of the material feeding and makes it inconvenient for the subsequent edge grinding of the inorganic board.

[0010] For example, in the demolding stage of inorganic boards, the traditional method involves using a demolding robot to suction the fabric from the center of the mold and then lifting it vertically upwards. However, this method is prone to causing internal cracks in the inorganic board. Each of these production stages can affect the quality of subsequent blank production. Summary of the Invention

[0011] In view of this, the present application provides an inorganic artificial stone slab production system and its production process, which solves the technical problems in the prior art such as low automation level, unreasonable overall design, and impact on the quality of slab production during the production and preparation of inorganic artificial stone slabs.

[0012] Therefore, this application provides an inorganic artificial stone slab production system, which has at least the following technical effects or advantages:

[0013] 1. The powder in the powder system is premixed in two stages by a first homogenizer and a second homogenizer before being conveyed to the mixing tank. Compared to the previous single-stage homogenization, the multi-stage homogenization effectively shortens the overall premixing time of the powder and increases the uniformity of the powder. Then, the rotation of the stirring claws and the revolution of the mixing tank are used to quickly and thoroughly mix the various powders to form the target mixture. Compared to the single and inefficient mixing of the stirring rods in the previous planetary mixers, this application utilizes the rotation of the stirring claws and the revolution of the mixing tank. The combined mixing method ensures more thorough and efficient mixing of the target mixture. The fabric mold and tough film are vacuumed using a fabric pneumatic system, which shapes the fabric mold with a base film. Compared to the previous method of laying paper, this solves the problem of wrinkles in the blank caused by wrinkles in the base film during fabric application. Then, the blank is vacuumed at constant pressure using a vacuum pump, and a vibrating motor drives the lower pressure head to compact the blank in the fabric mold, making the blank more compact and eliminating the influence of air bubbles in the blank.

[0014] This production system continuously and automatically feeds various powders into the mixing tank. Then, through the mixing system, vacuum feeding system, and pressing system, it automatically and efficiently produces blanks. The entire process requires minimal manual operation. Compared to the previous production methods that required manual feeding, mold handling, and instrument transport, this production system, with its reasonable optimization and highly automated control, effectively improves the production efficiency and quality of inorganic boards.

[0015] 2. The various additives in the additive storage module are metered by a metering device to make the amount of each additive more accurate; then the additive mixer performs preliminary mixing to make the various additives initially uniformly mixed, so as to provide sufficient mixing for subsequent mixing with other raw materials;

[0016] 3. The vacuum material distribution system intelligently and quantitatively distributes the target mixture using a weighing belt conveyor. This, combined with a material distribution homogenizing belt conveyor on the material distribution trolley for homogenization, and a material distribution transition belt conveyor for uniform material feeding, improves the uniformity of adjacent gaps in the target mixture and ensures the flatness of the distributed material. Furthermore, the material dispersing mechanism effectively prevents clumps and excessively high viscosity in the target mixture during distribution, ensuring the quality of subsequent inorganic board production.

[0017] 4. Demolding is achieved by using a demolding robot to adhere to the peripheral edge of the bottom surface of the fabric mold and then lifting it vertically upwards. A gap area is provided between the inner wall of the fabric mold and the two sides of the blank. When the demolding robot adheres to the peripheral edge of the bottom surface of the fabric mold and lifts it vertically upwards, air can enter from the gap area into the negative pressure layer between the bottom wall of the fabric mold's groove and the bottom surface of the blank. This allows the fabric mold to separate from the blank. Compared to the previous demolding method of using a demolding robot's suction cup to adhere to the middle of the fabric mold and lift it vertically upwards, this method effectively avoids excessive gravity on both sides when lifting the fabric mold vertically, preventing internal cracks in the blank, improving the demolding efficiency of the blank, and ensuring the yield and quality of subsequent inorganic boards.

[0018] This application provides a manufacturing process for inorganic artificial stone slabs, which has at least the following technical effects or advantages:

[0019] Before conveying various powders to the mixing tank, the powder system first accurately weighs them in a powder weighing hopper. The weighed powders then undergo initial premixing using high-pressure gas in a first homogenizer. Following this initial premixing, the powders are mechanically premixed again in a second homogenizer. Compared to traditional single-stage homogenization, multi-stage homogenization effectively shortens the overall premixing time, increases powder uniformity, and is fully automated, meeting the requirements for online automated powder premixing. Finally, the rotation of the mixing claws and the revolution of the mixing tank work together to thoroughly and efficiently mix the various powders into the target mixture, saving significant time and effort. The mixing time is controlled; the target mixture is transported to the vacuum fabrication system, and a fabrication mold with a bottom film is used to fabricate the blank to avoid wrinkles in the formed blank; the blank in the fabrication mold is vacuumed under constant pressure by the pressing system to remove air from the blank and prevent air from affecting the forming quality of the blank during the pressing process; after the blank is formed, the fabrication mold and the blank are separated by a demolding robot. By setting a gap area between the inner wall of the fabrication mold and the blank, the demolding robot breaks the negative pressure layer between the fabrication mold and the blank when it lifts the fabrication mold vertically, so that the blank can be demolded smoothly and quickly.

[0020] Through the automated production steps of the above-mentioned production system, the production efficiency and quality of subsequent inorganic boards can be effectively guaranteed, while saving a significant amount of production costs. Attached Figure Description

[0051] To better understand this technical solution, the following will provide a detailed description of the technical solution in conjunction with the accompanying drawings and specific implementation methods.

[0052] like Figure 1-14 As shown, an inorganic artificial stone slab production system is provided, which is mainly used to produce inorganic artificial stone type wall panels. It mainly includes a powder system 20, a mixing system 10, a vacuum feeding system 30, a pressing system 40, and a demolding system 50.

[0053] In practical applications, the raw materials for inorganic artificial stone slabs mainly include powder, additives, pigments, and aggregates; among which, additives include cooling water, alkaline water, and emulsions. There are two possible order for adding powder, additives, pigments, and aggregates: one is to add powder first, then additives, then pigments, and finally aggregates; the other is to add aggregates first, then additives, then pigments, and finally powder.

[0054] In this embodiment, the order of adding raw materials for the first type of inorganic artificial stone slab is described. The specific implementation is as follows:

[0055] The powder system 20 is used for weighing and premixing the powder materials in the inorganic artificial stone slab portion. The powder system 20 includes a powder tank 201, a first homogenizer 205, a second homogenizer 209, a premix buffer tank 210, and a powder weighing bin. The powder tank 201 serves as a container for storing various powders to be homogenized. A sieve 202 is installed at the outlet of the powder tank 201, allowing the various powders in the powder tank 201 to be screened by particle size. A screw feeder 203 is installed at the outlet of the sieve 202. The powder weighing bin includes a first powder weighing bin 204 and a second powder weighing bin 211. The inlet of the first powder weighing bin 204 is connected to the screw feeder 203. Therefore, after the various powders in the powder tank 201 are screened by the sieve 202, the screened powders can be conveyed to the first powder weighing bin 204 by the screw feeder 203 for initial weighing. The powders weighed in the first powder weighing bin 204 fall into the inner cavity of the first homogenizer 205 to prepare for the initial premixing work.

[0056] The first homogenizer 205 and the second homogenizer 209 are connected to each other in a sealed manner through a conveying pipe 208. Specifically, the inlet of the conveying pipe 208 is connected in a sealed manner with the outlet of the first homogenizer 205, and the outlet / air outlet of the conveying pipe 208 is connected in a sealed manner with the inlet of the second homogenizer 209.

[0057] The air inlet of the first homogenizer 205 is connected to a gas supply pipe 206, and the other end of the gas supply pipe 206 is connected to a gas supply device 207. The gas supply device 207 is a gas pump, gas pressure system, or other equipment that provides high-pressure gas. The gas supply device 207 is electrically connected to the controller. Therefore, the controller controls the gas supply device 207 to start supplying high-pressure gas or stop supplying high-pressure gas. The controller can control the gas supply device 207 to input the generated high-pressure gas into the inner cavity of the first homogenizer 205 through the gas supply pipe 206. The high-pressure gas delivered to the first homogenizer 205 blows or vulcanizes and disperses the powder, thereby completing the initial premixing of various powders in the first homogenizer 205.

[0058] Because the outlet of the first homogenizer 205 is sealed to one end of the conveying pipe 208, and the other end of the conveying pipe 208 is sealed to the inlet of the second homogenizer 209, after the powder in the first homogenizer 205 has been mixed by collision under the blowing of high-pressure gas, the pre-mixed powder can flow through the conveying pipe 208 to the inner cavity of the second homogenizer 209 along with the high-pressure gas in the first homogenizer 205. The second homogenizer 209 is equipped with stirring blades for stirring the powder. The stirring blades are controlled and driven by a motor. At this time, the stirring blades of the second homogenizer 209 can rotate at high speed to perform secondary premixing of the powder. The second homogenizer 209 drops the powder that has undergone secondary premixing into the premixing buffer tank 210, which is connected to the inlet of the second powder weighing bin 211 through another screw feeder 203. Therefore, after the powder in the premix buffer tank 210 is weighed again in the second powder weighing bin 211, it is transported to the mixing tank 1031 through multiple pipelines to prepare for mixing with other raw materials.

[0059] In this way, by setting up a multi-stage powder weighing process, the accuracy of the distribution ratio of various powders can be effectively improved; by pre-mixing the powders twice through the first homogenizer 205 and the second homogenizer 209, the various powders can achieve a more thorough and uniform mixing effect, and at the same time, the mixing time of various powders is greatly shortened.

[0060] The following requirements apply to the pressure, primary premixing, and secondary premixing values ​​of the high-pressure gas:

[0061] The pressure range of the high-pressure gas input to the first homogenizer 205 is 0.3 MPa to 0.5 MPa. In practical applications, the pressure of this high-pressure gas can be set to any one of 0.30 MPa, 0.35 MPa, 0.40 MPa, 0.45 MPa, or 0.50 MPa, among which setting the pressure of the high-pressure gas to 0.35 MPa is the optimal solution.

[0062] The initial premixing time of the powder in the first homogenizer 205 is 55s-65s. In practical applications, the initial premixing time can be set to any one of 55s, 58s, 60s, 62s, or 65s, among which setting the initial premixing time to 60s is the optimal solution.

[0063] The secondary premixing time of the powder in the second homogenizer 209 is 110s-130s. In practical applications, the initial premixing time can be set to any one of 110s, 115s, 120s, 125s, or 130s. Among these, setting the secondary premixing time to 120s is the optimal solution.

[0064] Considering the aforementioned settings for high-pressure gas pressure and the initial and secondary premixing times, the optimal implementation scheme is achieved by setting the high-pressure gas pressure to 0.35 MPa and the initial premixing time to 60 seconds and the secondary premixing time to 120 seconds. This is because when the high-pressure gas supplied by the gas supply device 207 to the first homogenizer 205 is at 0.35 MPa, the time required for the first homogenizer 205 to perform initial premixing of the powder using this 0.35 MPa high-pressure gas to achieve the desired mixing effect is exactly 60 seconds. However, when the high-pressure gas pressure is set to 0.3 MPa, the time required to achieve the initial premixing effect is 70 seconds, resulting in low premixing efficiency. While setting the high-pressure gas pressure to 0.50 MPa can shorten the initial premixing time, it can easily cause equipment fatigue to the pipelines and the first homogenizer 205, reducing its service life. In summary, the pressure of 0.35 MPa high-pressure gas and the initial premixing time of 60 seconds have advantages over the initial premixing of powder under high-pressure gas conditions of other pressure values.

[0065] While a secondary premixing time of 110 seconds achieves the desired premixing effect for the powder, it falls slightly short compared to a 120-second premixing time. A premixing time of 130 seconds, being too long, negatively impacts production efficiency. Therefore, a 120-second secondary premixing time offers advantages over secondary premixing of other powders and secondary premixing under unloading conditions.

[0066] In summary, dust collectors 2012 are installed on the top of the powder tank 201, the first homogenizer 205, and the second homogenizer 209 to collect dust. Dust is generated during powder conveying and homogenization. The dust collectors 2012 effectively solve the dust problem, protecting employee health and maintaining a clean operating environment. In the powder weighing and premixing process, multiple powder tanks 201, sieves 202, and screw feeders 203 can be installed, and then the powder is collected in the first homogenizer 205 for initial premixing. The number of dust collectors 2012 is determined by the number of powder tanks 201. In practical applications, the feeding of powder tank 201, the feeding of screw feeders 203, the weighing of powder in the weighing bin, the high-pressure gas delivery of the air supply device 207, and the premixing of the first homogenizer 205 and the second homogenizer 209 are all remotely automated through a controller or backend platform. The controller can be embedded with a control program, such as a PLC program. The controller can be a PLC module, a main control chip, etc., and there are no restrictions on this.

[0067] In this way, the powder in the powder tank 201 is conveyed to the powder weighing hopper by the screw feeder 203 for weighing. The weighing accuracy of the powder weighing hopper is less than 0.4%. After weighing, the powder falls into the first homogenizer 205 for initial premixing using high-pressure gas. The powder after initial premixing is then conveyed to the second homogenizer 209 via the conveying pipe 208 along with the high-pressure gas, where it undergoes a second premixing. Compared to the previous single-stage homogenization, the multi-stage homogenization effectively shortens the overall premixing time of the powder, increases the uniformity of the powder, and achieves a uniformity of over 95% between adjacent particles of various powders. Furthermore, the entire process is automated, meeting the requirements for online automated premixing of powder, thereby improving the production efficiency and quality of the subsequent inorganic board 1002.

[0068] The mixing system 10 includes a frame 101, a comprehensive mixer 102, and a rotating drum mechanism 103. The frame 101 is generally a frame made up of multiple slats. There are support plates on both sides of the frame 101, and an empty part is left in the middle of the frame 101 for installing the comprehensive mixer 102 and the rotating drum mechanism 103.

[0069] The integrated mixer 102 is used to mix various powders in the mixing drum mechanism 103. More specifically, the integrated mixer 102 has a mixing claw 1022 and a first driver 1023, which are mounted on a frame 101. In this embodiment, the first driver 1023 is a speed reducer, but it may also include a motor, cylinder, hydraulic cylinder, or other driving device with corresponding functions. Multiple first drivers 1023 can be installed. Therefore, when the first driver 1023 is energized, it drives the mixing claw 1022, so that the mixing claw 1022 receives power and rotates.

[0070] The rotating drum mechanism 103 includes a mixing drum 1031 and a second driver 1033, which is mounted on support plates on both sides of the frame 101. The second driver 1033, like the first driver 1023, is a speed reducer; however, the second driver 1033 may also include a motor, cylinder, hydraulic cylinder 1052, or other driving devices with corresponding functions. Therefore, when the second driver 1033 is energized, it drives the mixing drum 1031, causing the mixing drum 1031 to rotate in the opposite direction to the stirring claw 1022.

[0071] Therefore, various powders can be fully and efficiently mixed to form the target mixture by the rotation of the stirring claw 1022 and the revolution of the stirring barrel 1031. The time required to mix one ton of material to the specified uniformity is about twelve minutes, which is three to five minutes faster than the stirring rod of the previous planetary mixer.

[0072] In this way, the rotation of the stirring claw 1022 and the revolution of the stirring barrel 1031 in the opposite direction are used to stir various powders. Moreover, the rotation of the stirring claw 1022 and the revolution of the stirring barrel 1031 are controlled independently without conflicting or interfering with each other. This makes the target mixture more fully and efficiently stirred, effectively improving the production quality of the subsequent inorganic plate 1002.

[0073] The vacuum spreading system 30 is used to spread the target mixture in the mixing tank 1031 to form a blank. Specifically, the vacuum spreading system 30 has a spreading mechanism (not shown in the attached drawings), a conveyor belt 304, and a spreading pneumatic system 305. The conveyor belt 304 conveys a spreading mold 1001, on which a tough PE film is laid. Under the control of the belt conveyor encoder, the conveyor belt 304 conveys the spreading mold 1001 to the vacuum station. The spreading pneumatic system 305 performs a vacuuming action on the inner cavity of the spreading mold 1001, so that the tough PE film adheres to the inner bottom wall of the spreading mold 1001 and is shaped into the bottom film of the spreading mold 1001. The spreading mechanism is used to arrange the target mixture in the spreading mold 1001 with the built-in bottom film to form a blank.

[0074] The conveyor belt 304 transports the fabric mold 1001 containing the blank to the conveyor belt 91, and then the conveyor belt 91 transports it to the station of the film covering machine 31. The film covering machine 31 performs a film covering action on the upper surface of the fabric mold 1001 to complete the surface film covering of the blank.

[0075] In this way, the pneumatic fabrication system 305 shapes the inner wall of the fabric mold 1001 with a base film. Then, the conveyor belt 304 transports the fabric mold 1001 with the base film to the fabrication station for fabrication. This avoids the problem of the base film wrinkling during fabrication, forming pressing wrinkles on the blank, and solves the problem of wrinkles caused by the use of paper during fabrication, which affects the fabric thickness and makes subsequent processing of the inorganic board 1002 inconvenient. This effectively ensures the production quality of the subsequent inorganic board 1002.

[0076] The pressing system 40 is used to press the blank in the fabric mold 1001. The pressing system 40 includes a press, a lower pressing head 401, a pressing vacuum pump 402, and a vibration motor 403. The lower pressing head 401 is made of cast steel, which allows for a more balanced and stable pressing force. By using an airbag and hydraulic control to buffer the amplitude of the lower pressing head 401, it can automatically balance the excitation force. The vibration motor 403 drives the lower pressing head 401 through a coupling. The vibration motor 403 is equipped with a deflector block; adjusting the deflection of the deflector block adjusts the uniformity of the vibration motor, and simultaneously adjusts the magnitude and direction of the excitation force of the lower pressing head 401 to ensure that the excitation force on the blank surface is uniform. By using a frequency converter and a DC reactor to perform frequency conversion speed regulation of the vibration motor 403 and adjustable servo valve pressure, a high-frequency vibration multi-segment pressing configuration is formed. The vibration motor 403 is connected to the lower pressure head 401. After the vibration motor 403 is powered, it drives the lower pressure head 401 to move up or down along the vertical slide bar. The bottom of the lower pressure head 401 has a pressure frame, and the edge of the pressure frame is equipped with a sealing air tube.

[0077] In practical applications, the fabric mold 1001 is conveyed by the conveyor belt 91 to the area below the lower pressure head 401, causing the pressure frame cover to press onto the fabric mold 1001. The pressure vacuum pump 402 is connected to the inner cavity of the pressure frame through a constant vacuum proportional valve. The pressure vacuum pump 402 pumps air at constant pressure into the inner cavity of the pressure frame, specifically, above the blank in the fabric mold 1001, creating a vacuum environment inside the pressure frame. The vibration motor 403 drives the lower pressure head 401 to descend, performing high-frequency vibration to compact and press the blank in the fabric mold 1001 into a blank plate. The vacuum pump 402 evacuates for 12–18 seconds, with 15 seconds being optimal; the vibration motor 403 drives the lower pressure head 401 to descend for 5 seconds; in a vacuum environment, the vibration time of the vibration motor 403 is 68–78 seconds, with 70 seconds being optimal, significantly reducing the vibration time of the vibration motor 403.

[0078] In this way, by using a vacuum pump 402 to pump air at constant pressure into the inner cavity of the pressure frame, that is, above the blank in the fabric mold 1001, a vacuum environment is created inside the pressure frame. Under this vacuum environment, the vibration motor 403 drives the lower pressure head 401 to perform high-frequency vibration compaction on the blank in the fabric mold 1001, resulting in a flatness of less than 1 mm and a density of 2.4–2.5 g / cm³ after pressing. 3 This shortens the billet pressing time and reduces the evaporation of billet moisture, which can effectively improve the production efficiency and quality of subsequent inorganic plate 1002.

[0079] The pressing system 40 transports the pressed blank along with the fabric mold 1001 to the demolding system 50 via the conveyor belt 91 for demolding, so that the blank is separated from the fabric mold 1001.

[0080] In summary, the embodiments of this application provide an inorganic artificial stone slab production system, which has at least the following technical effects or advantages:

[0081] The various powders in the powder system 20 are premixed in two stages by a first homogenizer 205 and a second homogenizer 209 before being conveyed to a mixing tank 1031. Compared to the previous single-stage homogenization, the multi-stage homogenization effectively shortens the overall premixing time of the powders and increases their uniformity. Then, the rotation of the stirring claw 1022 and the revolution of the mixing tank 1031 work together to quickly and thoroughly mix the various powders to form the target mixture. Compared to the single and inefficient mixing of the stirring rod in the previous planetary mixer, this application utilizes the rotation of the stirring claw 1022 and the revolution of the mixing tank 1031 to quickly and thoroughly mix the various powders to form the target mixture. The combined revolution and stirring method allows for more thorough and efficient mixing of various powders. The fabric pneumatic system 305 uses vacuum treatment on the fabric mold 1001 and the tough film, ensuring that the fabric mold 1001 has a bottom film. Compared to the previous method of laying paper, this solves the problem of wrinkles in the blank caused by wrinkles in the bottom film during fabric application. Then, the blank is subjected to constant pressure vacuum treatment by the vacuum pump 402, and the vibrating motor 403 drives the lower pressure head 401 to compact the blank in the fabric mold 1001, making the blank more compact and eliminating the influence of air bubbles in the blank.

[0082] In this production system, various raw materials are continuously and automatically added to the mixing tank 1031. Then, the raw materials are automatically and efficiently produced into blanks through the mixing system 10, the vacuum feeding system 30, and the pressing system 40. The entire process requires minimal manual operation. Compared to the previous production methods that required manual feeding, mold handling, and instrument transportation, this production system, with its reasonable optimization and highly automated control, effectively improves the production efficiency and quality of the subsequent inorganic board 1002.

[0083] like Figure 1 and Figure 7 and Figure 8 As shown, an additive system 21, a pigment system 22, and an aggregate system 23 are provided between the powder system 20 and the mixing system 10; wherein,

[0084] The additive system 21 is used to transport additives to the mixing tank 1031 of the mixing system 10 and mix them with the powder. Specifically, the additive system 21 is used for pumping, metering, and mixing the additives in the inorganic artificial stone slab portion. The additive system 21 includes an additive storage module 21a, a transfer tank, a metering device, and an additive mixer 21e. The additive storage module 21a has a canister structure; wherein...

[0085] The auxiliary agent storage module 21a includes a chiller 21a1, an alkali water tank 21a2, and an emulsion tank 21a3. Therefore, the chiller 21a1 is used to store cooled tap water, the alkali water tank 21a2 is used to store alkali water, and the emulsion tank 21a3 is used to store emulsion.

[0086] The metering devices include an alkaline water metering device 21c and an emulsion metering device 21d.

[0087] The auxiliary agent transfer tank 21b includes a cooling water transfer tank 21b1, an alkaline water transfer tank 21b2, and an emulsion transfer tank 21b3. Therefore, the alkaline water in the alkaline water tank 21a2 is pumped to the alkaline water transfer tank 21b2 by a pump 21f. The outlet of the alkaline water transfer tank 21b2 is connected to the alkaline water metering device 21c. After being metered by the alkaline water metering device 21c, the alkaline water in the alkaline water transfer tank 21b2 is transported to the auxiliary agent mixer 21e through a pipeline.

[0088] The emulsion in the emulsion tank 21a3 is pumped to the emulsion transfer tank 21b3 by the pump 21f. The outlet of the emulsion transfer tank 21b3 is connected to the emulsion metering device 21d. After being metered by the emulsion metering device 21d, the emulsion in the emulsion transfer tank 21b3 is transported to the auxiliary agent mixer 21e through the pipeline.

[0089] The cooling water in the chiller 21a1 is pumped to the cooling water transfer tank 21b1 by the pump 21f. The outlet of the cooling water transfer tank 21b1 is connected to the additive mixer 21e. The cooling water in the cooling water transfer tank 21b1 is transported to the additive mixer 21e through a pipeline. Then, the additive mixer 21e can measure the cooling water.

[0090] The alkali metering device 21c measures the alkali, the emulsion metering device 21d measures the emulsion, and the additive mixer 21e measures the cooling water. The overall metering error is <0.5kg, thereby accurately controlling the amount of additives added and improving the production quality of the subsequent inorganic board 1002.

[0091] Cooling water, emulsion, and alkaline water are initially mixed by the additive mixer 21e and then transported to the mixing tank 1031 of the mixing system 10 to be mixed with the powder.

[0092] The pigment system 22 is used to transport pigments to the mixing tank 1031 of the mixing system 10 for mixing with powders and additives. Specifically, the pigment system 22 is used for metering and transporting pigments in the inorganic artificial stone slab portion, and can be used to color and add additives and solid additives to the inorganic artificial stone slab according to the process formula requirements. The pigments in the pigment system 22 are conveyed by the screw feeder 203 and metered by the metering device before being transported to the mixing tank 1031 for mixing with powders and additives.

[0093] The aggregate system 23 is used to transport aggregates to the mixing tank 1031 of the mixing system 10 for mixing with powders, additives, and pigments. Specifically, the aggregate system 23 includes an aggregate tank 231, a discharge conveyor 232, and an aggregate weighing bin; wherein, the aggregate tank 231 stores various aggregates, and the discharge port of the aggregate tank 231 is connected to the discharge conveyor 232; the aggregate weighing bin includes a first aggregate weighing bin 233 and a second aggregate weighing bin 234; the inlet of the first aggregate weighing bin 233 is connected to the discharge conveyor 232, and the various aggregates from the aggregate tank 231 fall into the discharge conveyor 232 through the discharge port. Then, the aggregate from the discharge conveyor 232 is conveyed to the first aggregate weighing bin 233 for initial weighing, and then conveyed to the second aggregate weighing bin 234 through the multi-stage conveyor belt 91. The second aggregate weighing bin 234 weighs the aggregate a second time and then conveys it to the mixing tank 1031 through multiple pipelines to mix with powder, additives and pigments.

[0094] In this way, multiple additives are stored in multiple additive storage modules 21a, and then the multiple additives are added and measured to the set value by a metering device, thereby automating the measurement of the amount of additives added, eliminating the error problem of manual operation in the past, and making the amount of various additives more accurate; then they are conveyed to the additive mixer 21e for preliminary mixing, so that the multiple additives are initially uniformly mixed; after preliminary uniform mixing, the multiple additives are conveyed to the mixing tank 1031 of the mixing system 10 to be mixed with the powder.

[0095] The metering accuracy of the metering device is less than 0.5%, which allows for the reasonable distribution of additives. The mixing of multiple additives by the additive mixer 21e can achieve a uniformity of more than 98% between adjacent additives, effectively improving the mixing effect between multiple additives. The additives are efficiently transported to the additive mixer 21e and the mixing system 10, ensuring sufficient mixing for subsequent mixing with other raw materials.

[0096] Then, the automatic supply of pigments by the pigment system 22 eliminates the problem of color inconsistency in the inorganic board 1002 caused by the previous manual addition of pigments, thus ensuring the production quality of the inorganic board 1002.

[0097] Then, by conveying the various aggregates in the aggregate tank 231 through multiple stages and weighing them multiple times in the aggregate weighing bin, the addition metering accuracy of the aggregates is made less than 0.6%; the aggregates in the aggregate tank 231 can be conveyed to the mixing tank 1031 in a better and more efficient manner, effectively improving the mixing and distribution effect of the aggregates.

[0098] like Figure 1-5 As shown, the integrated mixer also includes a support plate 1021 and a first transmission component 1024. The support plate 1021 is laid horizontally above the frame 101 and is fixedly connected to the support plates on both sides of the frame 101. Therefore, multiple first drivers 1023 are vertically fixed to the bottom of the support plate 1021 and close to both ends. The output shaft of the first driver 1023 passes through the bottom of the support plate 1021 and extends to the top of the support plate 1021.

[0099] The first transmission component 1024 is installed above the supporting horizontal plate 1021. In this embodiment, the first transmission component 1024 is a transmission belt, but it can also be a transmission chain or other transmission component with corresponding functions. The first transmission component 1024 is connected to the output shaft of the first driver 1023. In this embodiment, the stirring claw 1022 is vertically arranged below the supporting horizontal plate 1021. Multiple stirring claws 1022 can be provided, and the number of stirring claws 1022 corresponds to the number of first drivers 1023. The upper end of the stirring claw 1022 is the mounting end, and the lower end of the stirring claw 1022 is the stirring end.

[0100] The mounting end of the stirring claw 1022 penetrates the bottom of the supporting horizontal plate 1021 and extends to the top of the supporting horizontal plate 1021, where it is connected to the first transmission member 1024. The stirring end of the stirring claw has a multi-rod structure. Specifically, the portion of the stirring claw 1022 extending to the stirring tank 1031 has a horizontal bar, and multiple stirring rods are vertically fixed on the horizontal bar. The lower parts of the multiple stirring rods are triangular-rhomboid, thus making the lower end of the stirring claw 1022 a multi-rod, triangular-rhomboid structure to improve stirring efficiency. Therefore, after the first driver 1023 is energized, it drives the first transmission member 1024 through the output shaft. Then, the first transmission member 1024 drives the upper end of the stirring claw 1022, so that the stirring claw 1022 receives power to rotate.

[0101] The rotating drum mechanism 103 further includes a second transmission component 1034 and a rotary support mechanism 1032. In this embodiment, the rotary support mechanism 1032 is a rotary support bearing, mounted on a vacant portion in the middle of the frame 101. The second transmission component 1034 is a transmission gear, mounted on the output shaft of the second driver 1033. When the second driver 1033 is energized, it drives the second transmission component 1034 to rotate via the output shaft. Therefore, in practical applications, the second transmission component 1034 can be adjusted according to the replacement of the second driver 1033.

[0102] The mixing tank 1031 can be mounted on the radial rotating surface or the axial inner diameter mounting hole of the rotary support mechanism 1032 via a support shaft. The outer circumferential surface of the rotary support mechanism 1032 has an external gear, so the second transmission member 1034 can mesh with the rotary support mechanism 1032 to achieve the purpose of transmission connection. When the mixing tank 1031 is mounted on the rotary support mechanism 1032, since the lower end of the stirring claw 1022 is the stirring end, the lower end of the stirring claw 1022 will extend into the mixing tank 1031. Then, after the second driver 1033 is energized, it drives the rotary support mechanism 1032 through the second transmission member 1034. The rotary support mechanism 1032 synchronously drives the mixing tank 1031, so that the mixing tank 1031 revolves in the opposite direction to the stirring claw 1022, and the rotational speed of the stirring claw 1022 is greater than the rotational speed of the mixing tank 1031.

[0103] Further describing the stirring system 10, the supporting horizontal plate 1021 is provided with a plurality of transmission boxes 10a. The transmission box 10a is a box with semi-circular ends and a rectangular middle. The transmission boxes 10a are laid flat on the surface of the supporting horizontal plate 1021. The first transmission component 1024 is provided inside the transmission box 10a. Therefore, the number of transmission boxes 10a can correspond to the number of first transmission components 1024.

[0104] To enable the first driver 1023 to more effectively drive the stirring claw 1022, a drive wheel 10b is mounted on the output shaft of the first driver 1023, which passes through the bottom of the support plate 1021 and the transmission box 10a. A driven wheel 10c is provided at the upper end of the stirring claw 1022, which passes through the support plate 1021 and the transmission box 10a. That is, both the drive wheel 10b and the second pulley are installed inside the transmission box 10a, so the transmission box 10a can protect the first transmission component 1024, the drive wheel 10b, and the driven wheel 10c. In practical applications, the first transmission component 1024 is connected to the drive wheel 10b and the driven wheel 10c. When the first driver 1023 is energized, it drives the drive wheel 10b through the output shaft. Then, the first transmission slide drives the second transmission slide through the first transmission component 1024 to drive the stirring claw 1022 to rotate and stir the target mixture in the mixing tank 1031.

[0105] To achieve better coordination between the revolution of the mixing tank 1031 and the rotation of the stirring claw 1022, and to increase the mixing efficiency of the target mixture, the transmission of the mixing tank 1031 and the stirring claw 1022 is optimized as follows: According to the above scheme, the second transmission component 1034 is fixedly connected to the output shaft of the second driver 1033, and then the second transmission component 1034 is connected to the rotary support mechanism 1032. Therefore, when the second driver 1033 drives the second transmission component 1034 through the output shaft to drive the rotary support mechanism 1032, the rotary support mechanism 1032 can drive the mixing tank 1031 to revolve. When the mixing tank 1031 revolves and the stirring claw 1022 rotates, the rotational speed of the mixing tank 1031 is less than the rotational speed of the stirring claw 1022. In this embodiment, the revolution speed of the stirring tank 1031 is 7-8 r / min, and the rotation speed of the stirring claw 1022 is 120-135 r / min. Preferably, the revolution speed of the stirring tank 1031 is 7.5 r / min, and the rotation speed of the stirring claw 1022 is 128 r / min.

[0106] The structural design of the frame 101 and its assembly relationship with the mixing tank 1031 are further described. A base 1011 is installed in the empty space in the middle of the frame 101. Support plates on both sides of the frame 101 are assembled into a frame-shaped side frame 1012 with supporting legs. The base 1011 has a rectangular long plate, and support plates can be installed on both sides of the long plate. The two ends of the long plate and / or the support plates are then fixedly connected to the side frames 1012 on both sides of the frame 101, so that the base 1011 and the side frames 1012 are fixedly connected to each other to form the overall structure of the frame 101.

[0107] The rotary support mechanism 1032, used for mounting and driving the mixing tank 1031, is horizontally and movably mounted on the base 1011. When the second driver 1033 drives the rotary support mechanism 1032 through the second transmission member 1034, the rotary support mechanism 1032 can rotate freely on the base 1011. One end of the output shaft of the second driver 1033 is fixedly mounted on one side of the side frame 1012 and located at the bottom of the base 1011. In practical applications, the second driver 1033 can be used with a commutator. After the second driver 1033 is mounted on the side frame 1012, the output shaft is vertically mounted at one end of the second driver 1033 with the commutator. Then, the upper end of the output shaft passes through the base 1011 and is mounted on the second transmission member 1034. The second transmission member 1034 meshes with the rotary support mechanism 1032. This achieves the assembly relationship between the second driver 1033 and the frame 101, and drives the mixing tank 1031 to revolve by driving the second transmission component 1034 and the rotary support mechanism 1032.

[0108] Thus, the stirring system 10 has at least the following technical effects or advantages:

[0109] While the first driver 1023 drives the first transmission component 1024 to rotate the stirring claw 1022 and stir the target mixture, the second driver 1033 drives the second transmission component 1034 to rotate the mixing drum 1031 in the opposite direction relative to the stirring claw 1022. The rotation of the stirring claw 1022 and the revolution of the mixing drum 1031 are independently controlled and do not conflict or interfere with each other. Compared with the single and inefficient stirring of the stirring rod in the previous planetary mixer, this application uses a stirring method that combines the rotation of the stirring claw 1022 and the revolution of the mixing drum 1031, so that the target mixture is stirred more thoroughly and efficiently, and the quality of the subsequent inorganic plate 1002 is improved. Based on the multi-stage speed stirring of the rotation of the stirring claw 1022 and the revolution of the mixing drum 1031, the uniformity of the target mixture can be further improved by the two-stage homogenization of the stirring oscillating belt conveyor 104b and the stirring homogenizing belt conveyor 104c, so that the uniformity of the adjacent gaps of the target mixture reaches more than 95%.

[0110] like Figure 5 As shown, to further improve the material discharge efficiency of the mixing tank 1031, the discharge port 1035 is located in the middle of the bottom of the mixing tank 1031. In practical applications, the material discharge time for one ton is approximately five minutes, which is more than one minute faster than the previous method of setting the discharge port 1035 on the side wall of the mixing tank 1031. Since the mixing tank 1031 is mounted on the rotary support mechanism 1032 of the base 1011, a passageway is opened at the position corresponding to the discharge port 1035 on the base 1011 to avoid affecting the material discharge of the mixing tank 1031 through the discharge port 1035.

[0111] The base 1011 is also provided with a feeding assembly 105. Similarly, the feeding assembly 105 is also movable in the position where the feeding port is located. The feeding assembly 105 is located approximately below the bottom of the mixing tank 1031. The feeding assembly 105 includes a feeding gate plate 1051, a hydraulic cylinder 1052, and a connecting rod mechanism 1053. The diameter of the feeding port 1035 gradually increases from the inner bottom surface of the mixing tank 1031 to the outer bottom surface to form a cone shape. Therefore, the feeding gate plate 1051 is a cone-shaped structure so that the feeding gate plate 1051 can be matched and covered with the feeding port 1035.

[0112] In practical applications, the linkage mechanism 1053 includes a first linkage mechanism and a second linkage mechanism. One end of the first linkage mechanism is connected to the side of the discharge gate plate 1051 away from the discharge port 1035. A support seat is vertically installed on the side of the base 1011 facing the mixing tank 1031. The other end of the first linkage mechanism is movably connected to the upper end of the support seat. A mounting seat is fixed to the bottom of the base 1011. The second linkage mechanism has two or more sections. One end of one section is movably connected to the first linkage mechanism and the discharge gate plate 1051, and one end of the other section is movably connected to the mounting seat at the bottom of the base 1011. Then, one end of the hydraulic cylinder 1052 is fixedly connected to the mounting seat at the bottom of the base 1011. The piston rod at the other end of the hydraulic cylinder 1052 drives the junction of the two sections of the second linkage mechanism, thereby opening or sealing the discharge port 1035 according to the lever principle. This improves the material discharge efficiency of the mixing tank 1031 by automatically unloading material from the discharge port 1035.

[0113] After the side frames 1012 and the base 1011 are installed on the frame 101, in order to further improve the protection of the mixing tank 1031, a protective cover 109 is installed on each side of the side frame 1012 of the frame 101. The overall shape of the protective cover 109 is designed as an arc plate structure, so that the shape of the protective cover 109 matches the outer surface shape of the mixing tank 1031. The two protective covers 109 are located above the base 1011. One side of the two protective covers 109 is movably connected to one of the side frames 1012, and then the other side of the two protective covers 109 is locked to the other side frame 1012 by a movable buckle, so that the protective cover 109 and the side frame 1012 form an assembly relationship of flip-open or flip-close. A safety switch can be installed on the movable buckle connection between the protective cover 109 and the side frame 1012. This safety switch forms an interlock relationship with the mixing tank 1031, the mixing claw 1022, and other mechanisms. The switch is detected during the operation of the mixing tank 1031 or the mixing claw 1022. When the protective cover 109 is opened, the mixing tank 1031 and the mixing claw 1022 will automatically stop (safety protection).

[0114] Therefore, after the mixing drum 1031 is installed on the rotary support mechanism 1032 of the frame 101, protective covers 109 are added to both sides of the frame 101 to protect the normal revolution of the mixing drum 1031 in mixing the target mixture.

[0115] like Figures 3-5 As shown, based on the above technical solution description, the material feeding operation of the mixing tank 1031 is further optimized. A blowing mechanism 106 is provided on the base 1011 below the bottom of the mixing tank 1031. Specifically, the blowing mechanism 106 has a fixed seat 1061 and air nozzles 1062. The fixed seat 1061 is installed on the base 1011, and the air nozzles 1062 are connected to the fixed seat 1061. In this embodiment, six to eight air nozzles 1062 can be provided. The air nozzles 1062 are connected to the air source end through air pipes. During assembly, each air nozzle 1062 needs to face the periphery of the discharge port 1035. In practical applications, an anti-fouling layer is provided around the discharge port 1035. After the mixing tank 1031 feeds material, the anti-fouling layer reduces the residual material remaining around the discharge port 1035. Then, the blowing mechanism 106 is activated to blow high-pressure gas through the nozzle 1062 to remove residual material around the discharge port 1035. After blowing with the nozzle 1062, clean water from the water pipe assembly 10d installed on the support plate 1021 is used to wash the mixing tank 1031 and the mixing claws 1022. This efficiently and thoroughly completes the cleaning of the mixing mechanism.

[0116] In this way, by opening a discharge port 1035 in the middle of the bottom of the mixing tank 1031, the material discharge efficiency is higher and the material discharge is more thorough than that of the mixing tank 1031 with a discharge port 1035 on the side wall. Then, a blowing mechanism 106 is provided at the bottom of the mixing tank 1031. After the mixing tank 1031 finishes discharging material through the discharge port 1035, the air nozzle 1062 of the blowing mechanism 106 blows high-pressure gas to clean the residual material on the side of the discharge port 1035, so as to make the material discharge of the mixing tank 1031 more thorough and prevent material blockage.

[0117] The mixing tank 1031 is provided with a cover plate 107, which has multiple holes through which the mixing status of the target mixture inside the mixing tank 1031 can be observed. The cover plate 107 is movably connected to the side frames 1012 on both sides of the frame 101 by multiple crossbars or a horizontal movement switch. In actual operation, the cover plate 107 is opened by horizontal rotation, which solves the problem of the cover plate 1021 above blocking the opening of the cover plate 107, and also avoids the trouble of taking up too much space when opening it upwards.

[0118] A scraping mechanism 108 is fixed below the supporting horizontal plate 1021. The scraping mechanism 108 is mainly used to remove the residual material left on the inner wall of the mixing tank 1031 during unloading. Specifically, the upper end of the scraping mechanism 108 is fixedly connected to one side of the supporting horizontal plate 1021 and extends vertically downward into the mixing tank 1031. The scraping mechanism 108 mainly includes a scraper 1081 and a vibrator 1082. When the vibrator 1082 is powered on, it can vibrate the scraper 1081. Since the scraper 1081 is in close contact with the inner wall of the mixing tank 1031, when the mixing tank 1031 rotates, the mixing tank 1031 revolves relative to the scraper 1081. Then, the vibrator 1082 vibrates the scraper 1081 so that the scraper 1081 scrapes the inner wall of the mixing tank 1031. The residual material scraped off by the scraper 1081 falls down under the action of gravity.

[0119] Thus, by setting a scraping mechanism 108 on the support plate 1021 of the mixing mechanism for scraping off the residual target mixture on the inner wall of the mixing tank 1031, the vibrator 1082 of the scraping mechanism 108 is energized to make the scraper 1081 vibrate. Since the mixing tank 1031 revolves relative to the scraper 1081, when the mixing tank 1031 is revolving and discharging, the vibrating scraper 1081 will scrape off the residual target mixture splashed on the inner wall of the mixing tank 1031, thereby solving the problem that the inner wall of the mixing tank 1031 is not cleaned properly when discharging material in the past.

[0120] As attached Figures 1-2 As shown, the mixing system also includes a mixing and feeding belt conveyor 104a, a mixing and oscillating belt conveyor 104b, and a mixing and homogenizing belt conveyor 104c. The mixing and feeding belt conveyor 104a is located below the discharge port 1035 of the mixing tank 1031. The discharge end of the mixing and feeding belt conveyor 104a is connected to the feed end of the mixing and oscillating belt conveyor 104b. The target mixture formed by the mixing claws 1022 and the mixing tank 1031 falls into the mixing and feeding belt conveyor 104a through the discharge port 1035 of the mixing tank 1031 and is then transported to the mixing and oscillating belt conveyor 104b for initial homogenization. The discharge end of the stirring oscillating belt conveyor 104b is connected to the feed end of the stirring homogenizing belt conveyor 104c. The stirring oscillating belt conveyor 104b conveys the target mixture after the initial homogenization to the stirring homogenizing belt conveyor 104c for secondary homogenization. The target mixture after homogenization by the stirring homogenizing belt conveyor 104c is then conveyed to the material distribution mechanism.

[0121] In this way, the target mixture after mixing is further homogenized by the two-stage belt conveyors 104b and 104c, which continuously mix and homogenize the target mixture, providing a more uniform target mixture for subsequent fabrication and effectively ensuring the production quality of the inorganic board 1002.

[0122] The vacuum fabric distribution system 30 also includes a fabric distribution frame 306, a fabric distribution frame 307, and a lifting mechanism 308; the fabric distribution mechanism mainly includes a feeding hopper 301, a weighing belt conveyor 302, a material dispersing mechanism 303, and a fabric distribution trolley 309. The fabric distribution trolley 309 is movably arranged on the fabric distribution frame 306, and is equipped with a fabric homogenization belt conveyor 3091 and a fabric transition belt conveyor 3092.

[0123] The feeding hopper 301 is installed above the weighing conveyor belt 302, so that the feeding port of the feeding hopper 301 is aligned with the weighing conveyor belt 302. Therefore, the target mixture in the mixing tank 1031 is homogenized by the mixing and homogenizing conveyor belt 104c and then conveyed to the feeding hopper 301 and falls onto the weighing conveyor belt 302. The discharge end of the weighing conveyor belt 302 is set above the material homogenizing conveyor belt 3091, and the material dispersing mechanism 303 is set at the discharge end of the weighing conveyor belt 302. The weighing conveyor belt 302 is equipped with a weighing sensor, so the target mixture can be weighed to a set amount through the weighing conveyor belt 302 to accurately control the amount of target mixture added and ensure the production quality of the subsequent inorganic plate 1002. After being weighed, the target mixture on the weighing belt conveyor 302 is dispersed by the material dispersing mechanism 303 to prevent large clumps or excessively viscous target mixture from falling into the cloth homogenizing belt conveyor 3091 and affecting the cloth dispersing effect.

[0124] The fabric homogenizing conveyor belt 3091 homogenizes the target mixture to make the weighed target mixture more uniform. Another material dispersing mechanism 303 is provided at the discharge end of the fabric homogenizing conveyor belt 3091, which is used to further disperse the homogenized target mixture. The fabric transition conveyor belt 3092 is located below the fabric homogenizing conveyor belt 3091, so the target mixture on the fabric homogenizing conveyor belt 3091, after homogenization and dispersion, first falls onto the fabric transition conveyor belt 3092.

[0125] The fabric frame 307 is mounted on the fabric frame 306. A vacuum suction cup 5031 is provided on the side of the fabric frame 307. The fabric pneumatic system 305 is connected to the vacuum suction cup 5031 on the side of the fabric frame 307 through a pipeline.

[0126] Further description of the shaping of the bottom film of the fabric mold 1001: Under the control of the belt conveyor encoder, the conveyor belt 304 transports the fabric mold 1001 to the area below the fabric frame 307. The lifting mechanism 308 drives the fabric frame 306 to simultaneously lower the fabric frame 307 until the fabric frame 307 presses against the tough film and the four sides of the fabric mold 1001, so that a sealed inner cavity is formed between the tough film and the fabric mold 1001. The fabric pneumatic system 305 is set on both sides of the fabric frame 307. The fabric mold 1001 is provided with vacuum suction holes corresponding to the vacuum suction cups 5031 of the fabric frame 307. The fabric pneumatic system 305 has a fabric vacuum pump, which is connected to the vacuum suction holes of the fabric mold 1001 and performs vacuum treatment on the sealed inner cavity, so that the sealed inner cavity is in a vacuum state, so that the tough film adheres to the inner bottom wall of the fabric mold 1001 and is shaped into the bottom film of the fabric mold 1001.

[0127] The fabric carriage 309 reciprocates above the fabric frame 307. The fabric transition belt 3092 is mounted on the fabric carriage 309 at a 7° angle between its active and passive ends, allowing the target mixture to be distributed more evenly on the fabric transition belt 3092 and to be compacted. Therefore, as the fabric carriage 309 travels, the fabric transition belt 3092 evenly distributes the target mixture into the fabric mold 1001 of the fabric frame 307, forming a blank within the fabric mold 1001.

[0128] The rear end of the fabric feeding frame 306 is equipped with a recycling mechanism 312. When the fabric feeding trolley 309 travels to the end position of the fabric feeding, the excess target mixture on the fabric transition belt 3092 is pushed into the recycling mechanism 312. Therefore, the recycling mechanism 312 can be used to recycle the residual target mixture after the fabric is fed, so that the target mixture can be reused.

[0129] Thus, the vacuum fabric distribution system 30 has at least the following technical effects or advantages:

[0130] The vacuum fabric distribution system 30 intelligently and quantitatively distributes the target mixture using a weighing conveyor 302. This, combined with the homogenizing conveyor 3091 of the fabric distribution trolley 309 for homogenizing the weighed target mixture, and the uniform feeding of the target mixture using a transition conveyor 3092, improves the color uniformity of the subsequent blanks. Through this three-stage fabric distribution process—weighing conveyor 302, homogenizing conveyor 3091, and transition conveyor 3092—the uniformity of adjacent gaps in the target mixture reaches over 95%, and the flatness of the fabric distribution is ≤1mm. A material dispersing mechanism 303 is provided at the discharge end of both the weighing conveyor 302 and the homogenizing conveyor 3091. This dispersing mechanism effectively prevents the formation of clumps and excessive viscosity in the target mixture during fabric distribution.

[0131] The fabric vacuum pump of the fabric pneumatic system 305 is used to vacuum and shape the bottom film in the sealed inner cavity formed between the fabric mold 1001 and the tough film. This avoids the problem of the bottom film wrinkling during fabric application, which would cause wrinkles in the blank. It also solves the problem that the use of paper during fabric application would cause wrinkles that would affect the fabric thickness and make it inconvenient to process the inorganic board 1002 in the future, thus ensuring the production quality of the inorganic board 1002.

[0132] like Figure 1 and Figure 9 and Figure 11 and Figure 12 As shown, the demolding system 50 includes a first cover-support robot 501, a first flipping machine 502, and a demolding robot 503. The blank plate pressed by the pressing system 40, along with the fabric mold 1001, is transported to the demolding station of the demolding system 50. Then, the first cover-support robot 501, controlled by a servo motor, presses a spare bracket 1005 onto the blank plate inside the fabric mold 1001. By pressing the bracket 1005 onto the blank plate, subsequent handling and transportation of the blank plate are facilitated.

[0133] After the cover pressing process of bracket 1005 is completed, the blank plate, together with the fabric mold 1001 and bracket 1005, is conveyed to the first flipping station via conveyor belt 97, where it is flipped 180° by the first flipping machine 502. After the flipping process is completed, the blank plate, together with the fabric mold 1001 and bracket 1005, is conveyed to the station of the demolding robot 503 via conveyor belt 91. The inner wall of the fabric mold 1001 forms a gap area 1003 with the two sides of the blank plate, and the bottom surface of the fabric mold 1001 is set to be horizontal and smooth. Therefore, the suction cup 5031 of the demolding robot 503 can adhere to the peripheral edge of the bottom surface of the fabric mold 1001 and lift it vertically upwards by 10mm. The demolding robot 503 then remains stationary for three to five minutes, allowing air to enter from the gap area 1003 into the negative pressure layer 1004 between the bottom wall of the groove of the fabric mold 1001 and the bottom surface of the blank, thereby breaking the vacuum to separate the fabric mold 1001 from the blank. Then, the demolding robot 503 continues to lift vertically upwards to complete the demolding of the blank. In this embodiment, the fabric mold 1001 is made of rubber.

[0134] In this way, by using the suction cup 5031 of the demolding robot 503 to adhere to the peripheral edge of the bottom surface of the fabric mold 1001 and lifting it vertically upwards for demolding, gap areas 1003 are provided on the inner wall of the fabric mold 1001 and the two sides of the blank plate. When the suction cup 5031 of the demolding robot 503 adheres to the peripheral edge of the bottom surface of the fabric mold 1001 and lifts the fabric mold 1001 vertically upwards, air can enter the concave part of the fabric mold 1001 from the gap areas 1003. The negative pressure layer 1004 between the bottom wall of the groove and the bottom surface of the blank plate allows the fabric mold 1001 to separate from the blank plate. Compared with the previous demolding method of using the suction cup 5031 of the demolding robot 503 to hold the fabric mold 1001 vertically upward, this method can effectively avoid excessive gravity on both sides when the fabric mold 1001 is lifted vertically, effectively avoid the problem of internal cracks in the blank plate, improve the demolding efficiency of the blank plate, and ensure the yield and quality of the subsequent inorganic plate 1002.

[0135] like Figure 13As shown, further, the inorganic artificial stone slab production system of this application embodiment also includes a mold return system 70, which includes a second turning machine 701 and a mold cleaning machine 702. A conveyor belt 91 is provided between the second turning machine 701 and the mold cleaning machine 702. After the demolding robot 503 detaches, the fabric mold 1001 is conveyed to the second turning station via the conveyor belt 91. The fabric mold 1001 is turned 180° by the second turning machine 701. After being turned, the fabric mold 1001 is conveyed to the mold cleaning machine 702 via the conveyor belt 91 for cleaning, and then conveyed to the plate feeding belt 304 of the vacuum fabric feeding system 30 for standby.

[0136] In this way, the continuous operation between the second flipping machine 701 and the mold cleaning machine 702 of the mold return system 70 can effectively connect the work between the vacuum material feeding system 30 and the demolding system 50, and achieve the effect of efficient utilization of the material feeding mold 1001.

[0137] like Figure 1 and Figure 9 As shown, the inorganic artificial stone slab production system of this application embodiment also includes a curing system 60. The curing system 60 includes a stacking robot 601, a unloading robot 602, and a curing zone 1006. The stacking robot 601 is located at the front end of the curing zone 1006, and the unloading robot 602 is located at the rear end of the curing zone 1006. Therefore, the blank slab after demolding by the demolding robot 503, together with the bracket 1005, is conveyed together by the conveyor belt 91 to the rotating roller below the stacking robot 601. The stacking robot 601 clamps the bracket 1005 to perform a stacking action on the blank slab. The stacked blank slab, together with the bracket 1005, is conveyed to the curing zone 1006. The environment of the curing zone 1006 is set to constant temperature and humidity, with a temperature of 35-50°C and a humidity of 60%-70%. Therefore, the blank is cured into inorganic board 1002 under constant temperature and humidity conditions, with a curing cycle of 24 hours. After curing, the inorganic board 1002, together with the bracket 1005, is transported to the electric roller table below the unloading robot 602. The unloading robot 602 then unloads the multi-layered bracket 1005 containing the inorganic board 1002 onto the electric roller table.

[0138] like Figure 1 and Figure 9As shown, the inorganic artificial stone slab production system of this application embodiment also includes a slab unloading system 90, which includes a slab removal robot 901, a slab unloading robot 902, and a stacking rack 903. The slab removal robot 901 is located at the rear end of the unloading robot 602, and is used to separate the inorganic slab 1002 from the support frame 1005, so that the support frame 1005 is completely detached from the inorganic slab 1002. The unloading robot 902 is located at the rear end of the slab removal robot 901, and the inorganic slab 1002 removed by the slab removal robot 901 is transported to the workstation of the unloading robot 902 via a roller table. A stacking rack 903 for stacking the inorganic slab 1002 is arranged at the rear end of the unloading robot 902; therefore, the inorganic slab 1002 is unloaded onto the stacking rack 903 by the unloading robot 902 for convenient transportation and use.

[0139] like Figure 1 and Figure 14 As shown, the inorganic artificial stone slab production system of this application embodiment also includes a return system 80 for recycling and conveying the tray 1005. The return system includes a third flipping machine 801 and a second covering robot 802. The third flipping machine 801 is located at the front end of the second covering robot 802. The tray 1005 disassembled by the board removal robot 901 is conveyed to the third flipping station via a conveyor belt 91. The tray 1005 is flipped 180° by the third flipping machine 801. After flipping, the tray 1005 is conveyed to the second covering robot 802 of the return system 80 via the conveyor belt 91. The second covering robot 802 picks up the tray 1005 and places it on the conveyor belt 91, which then conveys it to the station of the first covering robot 501 of the demolding system 50 for standby.

[0140] In this way, the continuous operation between the third flipping machine 801 and the second cover robot 802 of the return support system 80 can effectively connect the work between the curing system 60 and the demolding system 50, and achieve the effect of efficient utilization of the bracket 1005.

[0141] like Figure 1-14 As shown, a production process for inorganic artificial stone slabs is provided, mainly used for producing inorganic artificial stone type wall panels. This embodiment uses a pressing method to prepare inorganic artificial stone slabs as an example, and describes the process by adding powder, additives, pigments, and bone meal sequentially into a mixing tank as raw materials. The operation method of the inorganic artificial stone slab production process is as follows:

[0142] The manufacturing process of inorganic artificial stone slabs includes the following steps:

[0143] (1) Add powder to mixing tank 1031 as follows:

[0144] The powder system 20 conveys powder. Various powders in the powder tank 201 are conveyed to the powder weighing bin by the screw feeder 203 for weighing, and then conveyed to the first homogenizer 205 of the powder system 20 for initial premixing with high-pressure gas. The powder that has undergone initial homogenization in the first homogenizer 205 is conveyed to the second homogenizer 209 through the conveying pipe 208 with the high-pressure gas for mechanical secondary premixing. The second homogenizer 209 conveys the powder that has undergone secondary premixing into the premixing buffer tank 210, and then into the mixing tank 1031 for mixing.

[0145] (2) The mixing system 10 mixes the various powders in step (1). The mixing tank 1031 of the mixing system is used to hold the various powders. The first driver 1023 drives the mixing claw 1022 through the first transmission member 1024. The rotation of the mixing claw 1022 is used to mix the various powders in the mixing tank 1031. At the same time, the second driver 1033 drives the rotary support mechanism 1032 through the second transmission member 1034. The rotary support mechanism 1032 drives the mixing tank 1031 to revolve relative to the mixing claw 1022. The rotation of the mixing tank 1031 is used to mix the various powders. The mixture is stirred and mixed by combining the rotation of the stirring claw 1022 with the revolution of the stirring drum 1031 to quickly and efficiently mix various powders to form a target mixture. Then, the target mixture is quickly fed into the mixing feed belt 104a through the discharge port 1035 at the bottom center of the mixing drum 1031. The target mixture is then conveyed by the mixing feed belt 104a to the mixing oscillating belt 104b for initial homogenization. The mixing oscillating belt 104b then conveys the raw material after the initial homogenization to the mixing homogenization belt 104c for secondary homogenization.

[0146] (3) The vacuum fabrication system 30 arranges the target mixture from step (2) into a blank. The target mixture in the mixing tank 1031 is transported to the discharge hopper 301 of the vacuum fabrication system 30 by the mixing and homogenizing belt conveyor 104c. The target mixture in the discharge hopper 301 is weighed by the weighing belt conveyor 302 and then the bulking mechanism 303 is used to break up large clumps and high viscosity of the target mixture. After being broken up once, the target mixture is fed into the fabrication homogenizing belt conveyor 3091 of the fabrication trolley 309. After homogenization, the target mixture is further dispersed and falls into the fabric transfer belt 3092 of the fabric carriage 309. The sealed inner cavity of the fabric mold 1001 is vacuumed and the bottom film is shaped by using the fabric pneumatic system 305. The fabric carriage 309 of the fabric mechanism travels above the fabric frame 306 while the fabric transfer belt 3092 evenly distributes the target mixture onto the fabric mold 1001 so that the target mixture forms a blank in the fabric mold 1001.

[0147] (4) The pressing system 40 presses the blank in step (3) into a blank plate. The vacuum fabrication system 30 transports the fabrication mold 1001 carrying the blank to the vacuum station of the pressing system 40 through the plate feeding belt 304. The pressing system 40 uses the pressing vacuum pump 402 to perform constant pressure vacuuming on the blank in the fabrication mold 1001. The vibration motor 403 drives the lower pressing head 401 to rise and fall in the vertical direction. The fabrication mold 1001 is transported to the film covering machine 31 for surface film covering through the plate feeding belt 304 and the conveyor belt 91. After the surface of the fabrication mold 1001 is covered with film, it is transported to the lower pressing head 401 through the conveyor belt 91. Then, the vibration motor 403 drives the lower pressing head 401 to perform high-frequency vibration compaction and pressurization on the blank in the fabrication mold 1001 that has completed vacuuming into a blank plate.

[0148] (5) The demolding system 50 removes the fabric mold 1001 from the blank in step (4), and the pressed blank, together with the fabric mold 1001, is transported to the cover support station, the flipping station, and the demolding station of the demolding system 50 for cover support, flipping, and demolding in sequence; specifically, the demolding system 50 uses the first cover support robot 501 to perform the support 1005 cover action on the surface of the blank; after the support 1005 cover action is completed, the first flipping machine 502 performs a 180° flipping action on the blank together with the fabric mold 1001 and the support 1005; after the flipping action is completed, the blank together with the fabric mold 1001 and bracket 1005 are conveyed to the bottom of demolding robot 503 via conveyor belt 91. The inner wall of fabric mold 1001 and the two sides of blank plate form a gap area 1003. When the suction cup 5031 of demolding robot 503 adsorbs the peripheral edge of the bottom surface of fabric mold 1001 and lifts it vertically upward, air enters from the gap area 1003 into the negative pressure layer 1004 between fabric mold 1001 and blank plate to break the vacuum, thereby separating fabric mold from blank plate. Then, demolding robot 503 continues to adsorb fabric mold 1001 and lift it vertically upward to complete the demolding of blank plate.

[0149] This application provides a manufacturing process for inorganic artificial stone slabs, which has at least the following technical effects or advantages:

[0150] Before conveying various powders to the mixing tank 1031, the powder system first accurately weighs them through a powder weighing bin. The weighed powders then undergo initial premixing using high-pressure gas in a first homogenizer 205. The resulting target mixture is then mechanically premixed again using a second homogenizer 209. Compared to traditional single-stage homogenization, multi-stage homogenization effectively shortens the overall premixing time, increases powder uniformity, and is fully automated, meeting the requirements for online automated powder premixing. Then, the rotation of the stirring claw 1022 and the revolution of the mixing tank 1031 work together to thoroughly and efficiently mix the various powders into the target mixture, saving significant mixing time. The standard mixture is conveyed to the vacuum fabrication system 30, and a fabrication mold 1001 with a bottom film is used to fabricate the blank to avoid wrinkles in the blank after molding. The blank in the fabrication mold 1001 is vacuumed under constant pressure by the pressing system 40 to release the air inside the blank, so as to avoid affecting the molding quality of the blank due to the presence of air in the blank during the pressing process. After the blank is formed, the fabrication mold 1001 and the blank are separated by the demolding robot 503. By setting a gap area between the inner wall of the fabrication mold 1001 and the blank, the demolding robot 503 breaks the negative pressure layer between the fabrication mold 1001 and the blank when it lifts the fabrication mold 1001 vertically, so that the blank can be demolded smoothly and quickly.

[0151] Therefore, through the automated production steps of the above-mentioned production systems, the production efficiency and quality of the subsequent inorganic board 1002 can be effectively guaranteed, while saving a lot of production costs.

[0152] Furthermore, after the powder system adds powder to the mixing tank in step (1), additives, pigments, and aggregates are added to the mixing tank sequentially through the additive system, pigment system, and aggregate system to mix with the powder; wherein,

[0153] The additive system 21 delivers additives. Cooling water in the chiller 21a1 is pumped to the cooling water transfer tank 21b1 via pump 21f. The cooling water in the cooling water transfer tank 21b1 is then transported to the additive mixer 21e via pipeline. The alkali water in the alkali water tank 21a2 is pumped to the alkali water transfer tank 21b2 via pump 21f. The alkali water in the alkali water transfer tank 21b2 is metered by the alkali water metering device 21c and then transported to the additive mixer 21e via pipeline. The emulsion in the emulsion tank 21a3 is pumped to the emulsion transfer tank 21b3 via pump 21f. The emulsion in the emulsion transfer tank 21b3 is metered by the emulsion metering device 21d and then transported to the additive mixer 21e via pipeline. The additive mixer 21e mixes the cooling water, alkali water, and emulsion and then transports the mixture to the mixing tank 1031 to mix with the target mixture.

[0154] The pigment system 22 conveys pigments. The pigments in the pigment system 22 are conveyed by the screw feeder 203 and metered by the metering device before being conveyed to the mixing tank 1031 to mix with the target mixture and additives.

[0155] The aggregate system 23 transports aggregates. The aggregates in the aggregate tank 231 are quantitatively transported to the first aggregate weighing bin 233 by the discharge conveyor 232. After the first aggregate weighing bin 233 performs the initial weighing, the aggregates are transported to the second aggregate weighing bin 234 by the multi-stage conveyor belt 91 for secondary weighing. The aggregates weighed in the second aggregate weighing bin 234 are transported to the mixing tank 1031 through pipelines to mix with the target mixture, additives, and pigments.

[0156] In this way, by sequentially adding additives, pigments, aggregates and powders into the mixing tank through the additive system, pigment system and aggregate system, the quality of the finished inorganic board 1002 is effectively improved.

[0157] Furthermore, the production process of inorganic artificial stone slabs also includes the following steps: curing system 60 for curing the blank slabs, unloading system 90 for unloading the inorganic slabs 1002, and return support system 80 for recovering the support brackets 1005.

[0158] After step (5), the curing system 60 cures the blank plate. The blank plate, which has completed the demolding process, is transported together with the bracket to the stacking station of the curing system 60. The stacking robot 601 holds the bracket 1005 to stack the blank plate. After the blank plate is stacked, it is transported to the curing area 1006 of the curing system 60 for constant temperature and humidity curing into the finished inorganic board 1002. After curing, the unloading robot 602 unloads the multi-layer bracket 1005 containing the inorganic board 1002 onto the electric roller table.

[0159] The unloading system 90 is used to unload the cured inorganic board 1002. The unloading system 90 includes a board removal robot 901, a board unloading robot 902, and a stacking rack 903. The inorganic board 1002, cured by the curing system 60, together with the bracket 1005, is transported to the board removal station of the unloading system 90 via an electric roller table. The unloading system 90 uses the board removal robot 901 to unload the inorganic board 1002 from the bracket 1005. The inorganic board 1002, after being removed from the bracket 1005, is transported to the board unloading station of the unloading system 90 via an electric roller table. Then, the board unloading robot 902 unloads the inorganic board 1002 onto the stacking rack 903 to complete the sorting and stacking of the inorganic board 1002.

[0160] The return system 80 is used to retrieve the bracket 1005 on the inorganic plate 1002. The bracket 1005 disassembled by the plate removal robot 901 is transported to the third flipping station via the conveyor belt 91. The third flipping machine 801 flips the bracket 1005 180°. After the flipping process is completed, the bracket 1005 is transported to the station of the second cover robot 802 via the conveyor belt 91. The second cover robot 802 transports the flipped bracket 1005 to the conveyor belt 91 and then to the demolding system 50 for recycling.

[0161] Furthermore, the inorganic artificial stone slab production process also includes the step of the mold recovery system 70 recovering the fabric mold 1001: the mold recovery system 80 recovers the fabric mold 1001 after step (5). The demolding robot 503 picks up the fabric mold 1001 that has been removed from the inorganic board 1002 and places the fabric mold 1001 on the conveyor belt 91 to the second flipping station. The second flipping machine 701 flips the fabric mold 1001 180°. Then the mold cleaning machine 702 cleans it. After cleaning, the fabric mold 1001 is conveyed to the vacuum fabric system 30 by the conveyor belt 91 for recycling.

[0162] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
