Description

Technical Field

[0001] The present invention relates to the field of forming and processing technology, and in particular to a fireproof material continuous forming and processing device and method based on PLC control. Background Art

[0002] With increasing fire safety requirements in the construction, transportation, and industrial sectors, the market demand for fireproof materials is growing. To meet the demands of large-scale production, continuous forming and processing equipment for fireproof materials has emerged. Currently, a variety of equipment for continuous forming and processing of fireproof materials are available on the market. While these equipment have achieved continuous production of fireproof materials to a certain extent, they still have many shortcomings in terms of production efficiency, product quality, degree of automation, and working environment.

[0003] Most of the existing continuous forming and processing equipment for fireproof materials lack multi-variable linkage closed-loop control logic. Usually, the key parameters of the fireproof material extrusion speed, conveyor belt running speed and cooling airflow intensity are independently controlled, and no effective linkage is achieved. When the extrusion speed increases, the conveyor belt linear speed and the cooling airflow intensity cannot be adjusted synchronously according to the preset ratio. This can easily lead to material accumulation problems, because the conveyor belt speed cannot keep up with the extrusion speed, causing the fireproof materials to pile up during the transportation process, affecting the continuity of production and product quality. At the same time, uneven cooling also occurs from time to time. Since the cooling airflow intensity cannot be adjusted accordingly according to the extrusion speed and conveyor belt speed, some fireproof materials may not be cooled sufficiently, while some may be over-cooled, thereby reducing the molding quality of the fireproof materials.

[0004] Most existing continuous forming and processing equipment for fireproofing materials lacks a comprehensive dust collection system. The conveying of fireproofing materials generates a large amount of dust. Without effective dust collection measures, this dust can spread throughout the workshop, polluting the work environment and posing a serious health threat to operators. It can also cause dust to adhere to the fireproofing materials, resulting in impurity contamination and lowering product quality.

[0005] Existing devices also have shortcomings in the molding and pressing of fireproof materials. The coordination between the molding hydraulic cylinder and the telescopic pressure rod is not precise enough, making it difficult to effectively mold and press the fireproof materials, and the fireproof materials cannot reach the required shape and density, and cannot meet different production needs. Existing continuous molding and processing devices for fireproof materials are not effective in cooling the molding mold. Some devices do not deliver cold air to the molding mold through the coordination of components such as the gas transmission serpentine pipe, filter tank, cold air delivery steering connecting pipe, cold air delivery pipe and cold air box, resulting in untimely cooling of the molding mold, slow molding speed of the fireproof material and low production efficiency. At the same time, due to the excessively high temperature of the molding mold, it may also affect the molding quality of the fireproof material, causing problems such as deformation and cracking.

[0006] Most existing devices do not have a dual pressure-displacement feedback loop. It is not possible to monitor the tensioning force in real time using a pressure sensor installed on the connecting arm of the pneumatic adjustment rod, nor is it possible to detect changes in the position of the tensioning roller using a displacement encoder built into the pneumatic cylinder adjustment rod. Therefore, when the conveyor belt becomes loose or too tight, the PLC cannot dynamically adjust the output pressure of the pneumatic cylinder based on the collected data. Furthermore, when encountering sudden belt breakage or material jamming, existing devices cannot react in a timely manner, unable to immediately reduce the extrusion motor speed and suspend conveying, which can easily lead to equipment damage, increased maintenance costs, and increased downtime. Therefore, a continuous forming and processing device and method for fireproof materials based on PLC control are proposed. Summary of the Invention

[0022] Compared with existing technologies, this invention offers significant advantages: The PLC incorporates a multivariable, closed-loop control logic with built-in multivariable coupling control algorithms. This system controls the fireproofing material extrusion speed via the fireproofing material extrusion motor, the conveyor belt speed via the fireproofing material forming conveyor belt power motor, and the cooling airflow intensity via the cooling air box regulating valve. As the extrusion speed increases, the PLC automatically increases the conveyor belt speed by a preset ratio and increases the cooling air flow rate, preventing material accumulation and uneven cooling.

[0023] By installing conveyor belt rotating rollers at both ends of the conveyor belt main frame and nesting the fireproof material forming conveyor belt, and at the same time using the fireproof material forming conveyor belt power motor to provide power, it is possible to achieve stable and efficient transportation of fireproof materials, ensure the continuity of the production process, and improve production efficiency.

[0024] The installation of the dust collection system includes the coordination of the conveyor belt dust collection trough shell, dust collection trough holes, fire-proof material molded conveyor dust collection pipe, conveyor belt dust collection fan blades, dust collection exhaust pipe and fire-proof material molded conveyor belt dust collection motor. It can effectively remove the dust generated during the transportation process, reduce dust pollution in the workshop, improve the working environment, protect the health of operators, and also help improve product quality and avoid dust from causing impurity contamination to fire-proof materials.

[0025] The coordination of the fireproof material conveying motor, power transmission belt, and conveying roller rotating shaft provides stable rotational power for the fireproof material conveying roller, and can flexibly adjust the conveying speed according to production needs to ensure smooth conveying of fireproof materials. The setting of the tensioning roller and adjustment components, using the buckle rod to adjust the pneumatic cylinder, the pneumatic cylinder to adjust the air rod, and the pneumatic rod connecting arm to adjust the position of the tensioning roller, thereby adjusting the tension during the conveying of fireproof materials, ensuring the stability of the fireproof material conveying, and reducing problems such as slipping and offset during the conveying process. Connecting the guide conveying rollers at the upper and lower ends of the side panels and installing the middle section support platform between the conveyor belt main frame and the bottom rod can provide good support and guidance for the fireproof materials, ensuring that the fireproof materials are accurately conveyed to the designated location, and improving the accuracy and quality of production.

[0026] The combination of a forming hydraulic cylinder and a telescopic pressure rod effectively forms and compresses the fireproofing material, achieving the desired shape and density to meet diverse production requirements. The coordinated operation of components such as the air delivery serpentine, filter canister, cold air delivery diversion connection pipe, cold air delivery pipe, and cold air box delivers cold air to the forming die, cooling the die and accelerating the forming process, improving production efficiency and ensuring the quality of the fireproofing material. The coordination of the fireproofing extrusion motor, motor power transmission belt, spiral extrusion shaft, and spiral extrusion pipe ensures uniform and stable extrusion of the fireproofing material. A dual pressure-displacement feedback loop is established between the fireproofing extrusion motor and the pneumatic cylinder for adjusting the rod: a pressure sensor mounted on the pneumatic rod's connecting arm monitors the tensioning force in real time; a displacement encoder built into the pneumatic cylinder's adjusting rod detects changes in the tensioning roller's position. The PLC uses this collected data to determine whether the conveyor belt is slack or overtightened and dynamically adjusts the cylinder's output pressure. If a sudden belt break or jam is detected, the PLC immediately reduces the fireproofing extrusion motor speed and halts conveying to prevent equipment damage. BRIEF DESCRIPTION OF THE DRAWINGS

Set a gas delivery serpentine pipe 41 above the forming mold 37, connect the end of the gas delivery serpentine pipe 41 to the filter tank 42, and connect the other side of the filter tank 42 to the cold air delivery diversion connecting pipe 43; connect the cold air delivery pipe 44 to the cold air delivery diversion connecting pipe 43, connect the cold air delivery pipe 44 to the cold air box 45, and nest a connecting flange 46 on the outer pipe to deliver cold air to cool the forming mold; Step 5: Install the fireproof material extrusion component on the bottom plate of the inspection platform 1. Install the fireproof material extrusion motor 47, connect the motor power transmission belt 48 to the fireproof material extrusion motor 47, connect the other end of the motor power transmission belt 48 to the spiral extrusion rotating shaft 49, connect one side of the spiral extrusion rotating shaft 49 to the spiral extrusion tube 50, and set a spiral extrusion spiral blade 51 on the outside of the spiral extrusion tube 50 for extruding the fireproof material; Step 6, debugging and operation: Check each component of the entire device to ensure that it is firmly installed and correctly connected; turn on the power supply and air pressure source, start the fireproof material forming conveyor belt power motor 12, the fireproof material forming conveyor belt dust suction motor 17, the fireproof material conveying motor 24, the forming hydraulic cylinder 39, and the fireproof material extrusion motor 47 equipment, and check the operation of each component; adjust the buckle rod to adjust the pneumatic cylinder 29, adjust the position of the tensioning roller 27 and the fireproof material output receiving buckle rod 33 to ensure the stability of the fireproof material transportation; open the cold air box 45, check whether the cold air delivery system is working properly and whether it can achieve cooling of the forming mold; test run the device.

[0045] Example 3: PLC-controlled continuous fireproof material forming and processing device, multi-variable linkage closed-loop control logic: The PLC has a built-in multi-variable coupling control algorithm. The fireproof material extrusion speed is controlled by the fireproof material extrusion motor 47, the conveyor belt speed is controlled by the fireproof material forming conveyor belt power motor 12, and the cooling airflow intensity is controlled by the regulating valve of the cold air box 45. When the extrusion speed increases, the PLC automatically increases the conveyor belt speed by a preset ratio and increases the cold air delivery to prevent material accumulation and uneven cooling.

[0046] A dual pressure-displacement feedback loop is established between the fireproof material conveying motor 24 and the pneumatic cylinder 29 for adjusting the rod. A pressure sensor mounted on the pneumatic rod's connecting arm 31 monitors tension in real time, while a displacement encoder built into the pneumatic cylinder's adjusting rod 30 detects changes in the position of the tensioning roller 27. Based on this collected data, the PLC determines whether the fireproof material forming conveyor belt 11 is slack or overtightened, dynamically adjusting the cylinder's output pressure. If a sudden belt break or jam is detected, the PLC immediately reduces the speed of the fireproof material extrusion motor 47 and halts conveying to prevent equipment damage.

[0047] The pneumatic tensioning mechanism is deeply integrated with PLC feedback control to achieve real-time sensing and active compensation of the tensioning state, surpassing traditional fixed or manual adjustment methods. Intelligent mold temperature prediction and cooling air adjustment algorithm: A multi-point temperature sensor array is placed inside the forming mold 37 to collect real-time temperature distribution in different areas of the mold. The PLC runs a built-in heat conduction prediction model, combining extrusion rate and material type to predict mold temperature rise trends. The electric valve opening on the cooling air delivery diversion connecting pipe 43 is automatically adjusted to dynamically control the cooling intensity of the U-shaped cooling air pipe 38. The system supports "staged cooling" mode: high cooling speed at the front end for rapid shaping, and slow cooling at the back end to reduce internal stress. This overcomes the limitations of traditional constant temperature control and introduces a predictive temperature control algorithm that balances cooling effectiveness and energy consumption optimization.

[0048] The PLC system integrates a fault knowledge base with the fault self-diagnosis and remote operation and maintenance interface, and can identify common abnormal patterns such as motor overload, insufficient air pressure, and blockage warnings. When an abnormality occurs, the fault code and treatment suggestions are automatically popped up, such as: "E203 - Fire-resistant material molding conveyor belt dust collection motor 17 is blocked, please check conveyor belt dust collection fan 14"; it supports uploading operating data to the cloud platform via industrial Ethernet or 4G module, realizing remote monitoring, parameter adjustment and firmware upgrade; it can be connected to the MES / ERP system for automatic archiving of production data and production scheduling.

[0049] The PLC is equipped with a touchscreen human-machine interface (HMI), allowing the operator to select different material types, such as calcium silicate board and magnesia fireproof board. Each material corresponds to a specific process recipe, including: extrusion speed setpoint corresponding to the fireproof material extrusion motor frequency; forming pressure threshold for the forming hydraulic cylinder; cooling time and air flow; and conveyor speed curve. The system can store 50 or more recipes, which can be recalled with a single click when switching between products, eliminating the need for resetting. This enables flexible "one machine, multiple materials" production, significantly improving the equipment's applicability and production changeover efficiency.

[0050] The PLC establishes multiple safety interlocks: If the guardrail door of maintenance platform 1 is not closed, the fireproof material extrusion motor 47 and the conveying system are prohibited from starting. If the dust collection motor 17 of the fireproof material forming conveyor belt is stopped for more than 10 seconds, an automatic alarm is triggered, indicating the risk of dust accumulation. If the telescopic pressure rod 40 does not reach the predetermined position during the downward movement of the forming hydraulic cylinder 39, it is judged as a mold jam, and the mold is immediately stopped and reversed. If the C-type buckle 34 of the buckle rod is not returned to its original position, the next batch of output is prohibited. This deep integration of mechanical safety and electrical control builds a full-link safety protection system that complies with the ISO 13849 standard.

[0051] The PLC monitors the power consumption of each motor in real time and adopts a variable frequency energy-saving strategy: during the no-material and no-load period, the speed of the fire-proof material forming conveyor belt power motor 12 is automatically reduced to the standby state; the fire-proof material forming conveyor belt dust collection motor 17 is only started when the material passes through the dust collection area, and is dormant at other times.

Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
