[0003] Ceramics come in many varieties, the most common being porcelain, pottery, and bricks. Different raw materials and firing processes affect the appearance, strength, and performance of ceramics.

Furthermore, the structure of sintering equipment is inconvenient for material management, and equipment maintenance and cleaning are also difficult. Based on this, those skilled in the art provide an intelligent production system and sintering equipment for alumina ceramics. Summary of the Invention

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0051] Example 1

[0052] Please see Figure 1 This embodiment provides an intelligent production system and sintering equipment for alumina ceramics, the process of which includes the following steps:

[0053] First, the raw materials need to be selected. High-purity alumina powder is used, and its particles are usually required to be fine and uniform in order to improve the density and performance of the final product.

[0054] Then, the material is granulated by a mixing and granulation equipment, shaped by a molding equipment, dried by a drying equipment, sintered by a sintering equipment, and finally finely processed by a post-processing and quality monitoring equipment, while the quality is monitored in real time.

[0055] In the mixing and granulation process, alumina powder is mixed with appropriate additives (such as binders and dispersants) and uniformly mixed using methods such as ball milling and vibratory milling. Then, granulation is performed to form particles suitable for molding.

[0056] Commonly used molding methods include compression molding, injection molding, and cold isostatic pressing. These methods are used to press the particles into the desired shape. The molded ceramic body is then dried to remove excess moisture and prevent cracking during subsequent sintering.

[0057] The dried material blank is placed in a sintering equipment for sintering, usually at a temperature between 1400-1700°C. The sintering process promotes the bonding between particles and improves the density and mechanical properties of the material.

[0058] The sintered material needs to be post-processed. After sintering, it needs to be machined, polished or surface treated to achieve specific surface finish and dimensional accuracy. During this process, its quality is intelligently monitored.

[0059] Based on this, sensor modules are installed on all the manufacturing equipment, and signals are transmitted via IoT wireless communication modules. The sensor modules include pressure sensors, temperature sensors, humidity sensors, etc. During the entire manufacturing process, the sensor modules monitor parameters such as temperature and pressure in real time and transmit the data to a smart terminal. The smart terminal connects to the sensor modules and the manufacturing equipment, and also transmits signals via IoT wireless communication modules. The smart terminal receives and analyzes the data from the sensor modules, uses time series analysis to build a production model, automatically adjusts equipment parameters and feeds them back to the manufacturing equipment. Multiple manufacturing devices optimize the production process through collaborative optimization, thereby achieving intelligent manufacturing processes that improve production efficiency, reduce energy consumption, and ensure product consistency and stable performance.

[0060] Time series analysis algorithms are statistical methods that identify and predict future trends by analyzing time series data. Time series data consists of observations collected in chronological order, typically within the same time interval (e.g., hourly, daily, or monthly). The core objective of time series analysis is to extract patterns from this historical data and use these patterns to make future predictions or detect anomalies.

[0061] In this intelligent alumina ceramic production system, the implementation of time series analysis algorithms typically involves the following steps:

[0062] 1. Data collection and preprocessing; 2. Selection of appropriate time series analysis algorithms; 3. Model training and evaluation; 4. Model prediction and equipment adjustment; 5. Model training and updating; 6. Feedback and optimization.

[0063] In this intelligent production system for alumina ceramics, temperature control of the sintering furnace is crucial, as temperature stability directly affects the sintering quality of the ceramics. Temperature fluctuations occur during high-temperature operation, sometimes even exhibiting a clustering effect (fluctuations are concentrated at certain times). To address these temperature fluctuations, the GARCH (Generalized Autoregressive Conditional Heteroskedasticity) model can be used to model and predict temperature fluctuations in the sintering furnace.

[0064] The intelligent terminal receives and analyzes data from the sensor module, establishes a production model based on time series analysis, automatically adjusts equipment parameters, and feeds them back to the manufacturing equipment. This includes using a GARCH model to control the temperature of the sintering equipment, specifically in the following manner:

[0065] S1. The sensor module is installed inside the sintering furnace to monitor temperature fluctuations and transmit the temperature data to a smart terminal via an IoT wireless communication module; the sensor records the temperature changes inside the furnace in real time, and these data constitute a time series.

[0066] S2. The smart terminal trains a GARCH model based on temperature data to capture the clustering effect of temperature fluctuations. The temperature time series is set as follows: ,in The conditional variance is , where Y t The temperature value at the current moment. Z is the error term. t It is white noise. The conditional variance, i.e., the magnitude of temperature fluctuation, is represented by α0, called the constant term (or intercept term), which represents the minimum baseline value of temperature fluctuation under the condition of no fluctuations or shocks. It sets the starting point for the conditional variance, i.e., the basic fluctuation level. α1 is called the "ARCH term" coefficient, representing the square of the prior period error (…). The value indicates the extent to which past fluctuations (i.e., drastic or abnormal temperature fluctuations) have influenced the current temperature fluctuation. β1 is called the "GARCH term" coefficient, representing the previous conditional variance (…). The value of α0 indicates the persistence of the current fluctuation. A larger value indicates a stronger persistence of the fluctuation, suggesting that the temperature fluctuation tends to continue the previous fluctuation pattern. By estimating parameters such as α0, α1, and β1, the model predicts temperature fluctuations to adjust the control response accordingly.

[0067] S3. Based on the GARCH model, the system predicts temperature fluctuations and adjusts the heating power of the sintering furnace in advance to smooth temperature changes. If the predicted fluctuations exceed the tolerance range, the intelligent terminal dynamically adjusts the heating or cooling rate to maintain temperature stability. At the same time, data is shared among the sintering equipment to collaboratively optimize temperature control.

[0068] S4. With continuous data input, the GARCH model automatically updates its parameters to better adapt to actual temperature fluctuations. This adaptive characteristic enables continuous optimization of temperature control strategies as production conditions change.

[0069] In summary, time series analysis algorithms, through precise prediction and automated adjustment, ensure high efficiency in the production process and stable product quality in the intelligent alumina ceramic production system. This method can respond to changes in the production environment in real time, thereby optimizing the production process and reducing production costs.

[0070] Example 2

[0071] Please see Figures 2 to 14 This embodiment provides a sintering equipment for intelligent production of alumina ceramics, which is one part of the intelligent production in Embodiment 1. The specific structure of the sintering equipment is as follows: it includes a base 1, the bottom of which is provided with multiple support feet, which play an anti-slip and buffering role, making it more stable. At the same time, a furnace body 2 is set in the middle of the upper end of the base 1. The furnace body 2 is the sintering equipment, which is used to fire alumina ceramics. A furnace cover 3 is installed at the upper end of the furnace body 2. The furnace cover 3 is used to seal the furnace body 2 and ensure the sealing effect during ceramic firing.

[0072] A lifting mechanism 4 is provided on the upper end of the base 1 on the outside of the furnace body 2. The lifting mechanism 4 is connected to the furnace cover 3, which can drive the furnace cover 3 to move up or down, thereby opening the furnace cover 3 or sealing the furnace body 2 during firing.

[0073] Furthermore, a material rack 5 is provided inside the furnace body 2. The top of the material rack 5 is connected to the furnace cover 3. When the furnace cover 3 rises or falls, the material rack 5 also moves along with it. When the furnace cover 3 rises, it can drive the material rack 5 to extend out of the furnace body 2, so as to place alumina ceramic raw materials or remove the fired ceramics. When the furnace cover 3 falls, the material rack 5 moves down and is placed inside the furnace body 2.

[0074] In this embodiment, the improvement is aimed at the material rack 5. In the prior art, the material rack 5 is just a simple support plate structure, which cannot realize multi-layer placement, classified placement, etc., and has limitations in use. Moreover, after the support plate has been placed with materials for a long time and fired at high temperature, it is easy to wear and have raw materials stuck to it, which requires cleaning. It is also not easy to disassemble and replace.

[0075] Based on the above problems, the material rack 5 in this invention has a multi-layer structure, which can be placed according to different material categories, and its height is adjustable to adapt to different materials. At the same time, it is a split structure, which is easy to disassemble, making it convenient to pick up and put in materials, and also facilitating its disassembly and maintenance.

[0076] Specifically, a sealing groove is provided on the lower side of the furnace cover 3, and the sealing groove is inserted into the upper wall of the furnace body 2 to achieve a good sealing effect. In addition, a threaded seat 32 is provided on the left side of the furnace cover 3, and a limiting plate 31 is provided on its right side. The threaded seat 32 is threadedly connected to the lifting mechanism 4, while the limiting plate 31 is slidably connected to the lifting mechanism 4 to achieve the limiting effect.

[0077] The lifting mechanism 4 includes two side plates 41, located on the left and right sides of the furnace body 2 respectively. Their bottoms are fixed to the base 1. A sliding rod 44 is installed inside the right side plate 41, passing through a limiting plate 31 and fixed to the base 1. The limiting plate 31 can slide on the sliding rod 44, and the two work together to achieve a limiting function. A motor 42 is installed on the top of the left side plate 41. A lead screw 43 is connected to the motor shaft of the motor 42. The bottom of the lead screw 43 rotates on the base 1, and a screw thread is sleeved on the lead screw 43. The threaded seat 32 is connected to the inner wall of the left side plate 41, which is slidably connected to the end of the threaded seat 32 when the motor 42 is working, so that the threaded seat 43 can rotate. After the threaded seat 32 moves, the furnace cover 3 will move together. The limiting plate 31 will also move up or down on the slide rod 44 to realize the lifting and lowering of the furnace cover 3, so that it can be opened or closed.

[0078] When the furnace cover 3 rises or falls, the material rack 5 fixed at its bottom also moves along with it. The material rack 5 includes a vertical rod 51, the top of which is fixedly connected to the furnace cover 3. Multiple equally spaced insertion holes 54 are provided on the side wall of the vertical rod 51 from top to bottom. Furthermore, multiple material trays 52 are fitted onto the vertical rod 51. The material trays 52 are fixedly connected to the vertical rod 51 by pins 53, which limit the movement of the material trays 52. Similarly, removing the pins 53 allows the material trays 52 to be moved, thereby... The distance between the upper and lower material trays 52 can be adjusted to accommodate different material heights. When firing materials, they can be placed on different layers of material trays 52 according to the different types of materials. Moreover, each material tray 52 is also equipped with partitions, which can also be used to classify and place materials. If the quantity of materials is small, only one material tray 52 can be installed. In this case, it can also play the role of classifying and placing materials. The material trays 52 can be set as needed. They are fixed by pins 53, which realizes convenient installation and disassembly, and facilitates the maintenance of the material trays 52 themselves.

[0079] The tray 52 includes a base 521, a fixing seat 522 in the middle of the base 521, the fixing seat 522 is sleeved on the vertical rod 51, and a fixing hole 523 is provided on the side wall of the fixing seat 522, which corresponds to the insertion hole 54. The pin 53 is inserted into the fixing hole 523 and the insertion hole 54 to connect the fixing seat 522 and the vertical rod 51 together to form a whole, thereby realizing the installation and fixing of the tray 52.

[0080] The upper part of the base 521 is divided into multiple grooves 524 on the outer side of the fixed base 522. A movable plate 525 is placed in the groove 524. The movable plate 525 is inserted into the groove 524. The insertion form allows the movable plate 525 to be separated from the base 521. Materials can be placed on the movable plate 525 and then placed into the groove 524. At the same time, the fired ceramics can be directly removed as a whole, improving convenience.

[0081] Furthermore, a protective plate 526 is provided on the upper part of the moving tray 525. The protective plate 526 is in direct contact with the material and can prevent adhesion, thus avoiding affecting the sintering quality of the material. The protective plate 526 is installed on the upper surface of the moving tray 525 and plays a protective role for the entire tray 52. ​​The moving tray 525 has a fixing component 527 inside, and the protective plate 526 is fixed to the moving tray 525 through the fixing component 527. The protective plate 526 and the moving tray 525 are not fixedly connected, but have a separate structure. Therefore, when the protective plate 526 has wear problems, it can be replaced separately without replacing the entire moving tray 525. The protective plate 526 is smaller and lighter, making it easier to replace and saving resources.

[0082] The movable tray 525 is equipped with handles 5251 at both ends, which can be easily lifted and transported. Two slots 5252 are provided on the movable tray 525 for insertion and fixing with the protective plate 526. The movable tray 525 has a hollow structure inside, in which a fixing component 527 is installed. The hollow structure includes a cavity 5255 in the middle, and a through hole 5256 is provided on the outside of the cavity 5255. A through groove 5254 is provided on both the left and right sides of the cavity 5255. A sliding groove 5253 is provided at the end of the through groove 5254, and the sliding groove 5253 communicates with the slot 5252.

[0083] The fixing component 527 includes a rotating shaft 5271, which is installed in the through hole 5256. The outer end of the rotating shaft 5271 is provided with a rotating hole 5272, and its inner end is located in the cavity 5255 and is rotatably connected to its side wall. Steel wires 5273 are connected to both sides of the rotating shaft 5271. The steel wires 5273 pass through the through groove 5254 and are connected to the limiting rod 5274 located in the slide groove 5253. One end of the limiting rod 5274 near the slot 5252 is set as an oblique smooth surface, and the other end is provided with a spring 5275. The spring 5275 can support the limiting rod 5274 to move away from the rotating shaft 5271, thereby fixing the protective plate 526. In use, the bottom of the protective plate 526 is inserted into the slot 5252.

[0084] The lower end of the protective plate 526 is provided with a plate 5261 corresponding to two slots 5252. The side wall of the plate 5261 is provided with a limiting hole 5262, and the bottom of the plate 5261 is provided with a slope 5263. When the protective plate 526 is installed, the plate 5261 is aligned with the slot 5252 and then pressed down. The plate 5261 will move down in the slot 5252. At the same time, its slope 5263 will squeeze the limiting rod 5274, causing it to move into the slide groove 5253 and squeeze the spring 5275. After it continues to move down, the limiting rod 5274 will be inserted into the limiting hole 5262 under the action of the spring 5275, thereby achieving the fixed limiting of the protective plate 526.

[0085] When removing it, an external tool is inserted into the rotating hole 5272, and then the rotating shaft 5271 is rotated. After the rotating shaft 5271 rotates, it can wind the steel wire 5273. When the steel wire 5273 is wound, it will pull the limiting rod 5274 to move towards each other in the sliding groove 5253, thereby disengaging it from the limiting hole 5262. In this way, the protective plate 526 can be removed. Then, the rotating shaft 5271 is released, and under the action of the spring 5275, the limiting rod 5274 can return to its original position.

[0086] It should be noted that a control panel and display screen can be installed on the side plate 41 of the lifting mechanism 4 to realize intelligent operation of the entire system. Existing technology can be used, and the specific structure and principle will not be described in this application.

[0087] In this invention, the material rack 5 is composed of a vertical rod 51 and multiple material trays 52 that can be detachably installed. This allows the material trays 52 to be set as needed and according to the volume of the materials. At the same time, they can be placed in layers and classified for easy access. They can adapt to different working scenarios and have good practicality. This overcomes the limitations of the prior art, which only uses a support plate to place materials. Moreover, the protective plate 526 on the material tray 52 is easy to disassemble and can be easily replaced after being damaged during long-term use, which is conducive to disassembly and maintenance.

[0088] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
