Description

Technical Field

[0001] This invention belongs to the field of polymer material processing technology, specifically a dynamic temperature-controlled extrusion molding equipment for the production of insulating materials. Background Technology

[0002] Insulating materials are an indispensable basic material in industries such as power, electronics, and communications. Their quality directly affects the safe operation and service life of electrical equipment. Extrusion molding is the main process for producing insulating materials, and temperature control is the most critical link in the extrusion molding process. The accuracy of temperature control directly affects the plasticization degree, molecular structure orientation, and electrical and mechanical properties of the final product.

[0003] In existing technologies, the temperature control systems of extrusion molding equipment used for insulating material production generally suffer from the following problems:

[0004] (1) Temperature sensors are usually installed on the outer wall of the extruder barrel. They measure the barrel temperature rather than the actual temperature of the material. There is a large temperature lag and measurement error, generally within ±3-5℃, which cannot accurately reflect the true plasticization state of the material.

[0005] (2) The temperature of each section of the extruder is controlled independently by PID. The lack of coordination between the sections can easily lead to an unreasonable temperature gradient of the material in the screw, resulting in local overheating or insufficient plasticization, which affects the consistency of the product.

[0006] (3) The control algorithm uses PID control with fixed parameters, which cannot adapt to the influence of factors such as material batch differences, ambient temperature changes and equipment wear. It requires frequent manual adjustment of parameters, resulting in low control accuracy and high labor intensity.

[0007] (4) Cooling stage usually uses cooling water at a single temperature. If the cooling speed is too fast, it will cause large internal stress in the product, which will easily lead to defects such as cracking and deformation, and reduce the electrical insulation performance and mechanical strength of the product.

[0008] (5) Lack of comprehensive real-time detection of material status makes it impossible to dynamically adjust process parameters according to the actual status of materials. Production can only be carried out based on experience, resulting in large fluctuations in product quality and low pass rate.

[0009] Meanwhile, existing technologies detect temperature by installing temperature sensors on the outer wall of the barrel and use PID control algorithms for temperature regulation. However, the system still suffers from problems such as temperature measurement lag and lack of coordination in the independent temperature control of each section, which cannot meet the requirements for the production of high-performance insulation materials.

[0010] Therefore, to address the above issues, it is necessary to develop a dynamic temperature control extrusion molding equipment that can detect the actual temperature of the material in real time, achieve multi-segment coordinated temperature control, and adaptively adjust process parameters. Summary of the Invention

[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dynamic temperature-controlled extrusion molding equipment for the production of insulating materials, so as to solve the problems of lagging temperature control, uneven plasticization, large internal stress of products, and poor batch consistency in the production of insulating materials in the prior art.

[0012] To achieve the above objectives, the present invention provides the following technical solution: a dynamic temperature-controlled extrusion molding equipment for the production of insulating materials, comprising an extruder main body module, a multi-segment collaborative temperature control module, a material status real-time detection module, an adaptive PID control module, and a gradient cooling molding module.

[0013] The main extruder module is used to melt and plasticize insulating raw materials and extrude them, including a screw, barrel, drive motor and gearbox.

[0014] The multi-segment coordinated temperature control module is connected to the main extruder module and is used to perform independent and coordinated temperature control on the feeding section, plasticizing section, homogenizing section and extrusion section of the extruder.

[0015] The real-time material status detection module is installed inside the main extruder module to detect the material temperature, pressure, and screw torque at different locations inside the screw in real time.

[0016] The adaptive PID control module is electrically connected to the multi-segment collaborative temperature control module, the real-time material status detection module, and the extruder main module, respectively, and is used to dynamically adjust the temperature control parameters and screw speed based on the material status detection data.

[0017] The gradient cooling forming module is connected to the outlet of the main extruder module and is used to perform stepped cooling forming on the extruded insulation material.

[0018] Furthermore, the real-time material status detection module includes at least 6 sets of built-in temperature sensors, 3 sets of pressure sensors, and 1 set of torque sensors. The 6 sets of built-in temperature sensors are respectively installed in the middle of the feeding section, the inlet of the plasticizing section, the middle of the plasticizing section, the outlet of the plasticizing section, the middle of the homogenization section, and the inlet of the extrusion section. The sensor probes are in direct contact with the material, which can accurately measure the actual temperature of the material and eliminate the lag and error of the barrel outer wall temperature measurement.

[0019] Furthermore, the built-in temperature sensor uses an armored platinum resistance sensor with a response time of less than 0.5 seconds and a measurement accuracy of ±0.1℃. The sensor probe surface is coated with a polytetrafluoroethylene insulating coating with a thickness of 0.2-0.3mm, which ensures the insulation performance of the sensor without affecting the flow and plasticization of the material.

[0020] Furthermore, the multi-segment collaborative temperature control module includes four independent heating units and four independent cooling units, corresponding to the feeding section, plasticizing section, homogenizing section and extrusion section of the extruder, respectively. Each heating unit adopts a ceramic heating coil, which provides uniform heating and high thermal efficiency. Each cooling unit adopts a water-cooled jacket structure, which provides fast cooling speed and high control precision.

[0021] Furthermore, the adaptive PID control module can automatically adjust the power of the corresponding heating and cooling units based on the temperature difference between two adjacent material sections detected by the real-time material state detection module, so that the temperature gradient of the material in the screw is kept within a preset range, ensuring that the material can obtain the best plasticizing effect in each section.

[0022] Furthermore, the adaptive PID control module has a built-in material property database and an ambient temperature compensation algorithm. The material property database stores the optimal temperature curves and plasticizing parameters for different grades of insulation materials. During production, simply select the corresponding material grade, and the system will automatically load the optimal process parameters. The ambient temperature compensation algorithm can automatically correct the temperature control setpoint according to the ambient temperature, eliminating the impact of ambient temperature changes on product quality.

[0023] Furthermore, the gradient cooling molding module includes a first cooling section, a second cooling section, and a third cooling section connected in sequence. Each cooling section is equipped with an independent temperature sensor, a flow regulating valve, and a circulating water pump, which can control the temperature and flow rate of the cooling medium in each section to achieve stepped cooling and effectively reduce the internal stress of the product.

[0024] Furthermore, the cooling medium temperature in the first cooling section is 30-40°C lower than the material temperature in the extrusion section, the cooling medium temperature in the second cooling section is 20-30°C lower than the first cooling section, and the cooling medium temperature in the third cooling section is room temperature. This gradient cooling method enables the material to cool slowly and evenly, avoiding internal stress caused by excessively fast cooling.

[0025] Furthermore, it also includes a human-machine interaction module, which is electrically connected to the adaptive PID control module. It is used to display equipment operating parameters, set control parameters, and store production data. The human-machine interaction module adopts a touch screen operation interface, which is simple and convenient to operate.

[0026] Furthermore, the adaptive PID control module also has a fault self-diagnosis function. When abnormal temperature, pressure or torque is detected, it can automatically issue an alarm signal and take corresponding protective measures, such as reducing the screw speed or stopping heating, to ensure equipment and production safety.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) The present invention uses a built-in temperature sensor array to directly measure the actual temperature of the material at different positions inside the screw. The response time is less than 0.5 seconds and the measurement accuracy can reach ±0.1℃. It completely solves the problems of temperature measurement lag and large error in the prior art and can accurately reflect the true plasticization state of the material.

[0029] (2) The present invention adopts multi-segment collaborative temperature control technology. The adaptive PID control module can automatically adjust the heating and cooling power of each segment according to the temperature difference between two adjacent material segments, so that the temperature gradient of the material in the screw is kept within the optimal range, ensuring uniform plasticization of the material and improving the consistency of the product.

[0030] (3) The present invention adopts an adaptive PID control algorithm, with a built-in material characteristic database and an ambient temperature compensation algorithm, which can automatically adapt to the influence of factors such as material batch differences, ambient temperature changes and equipment wear, without the need for frequent manual parameter adjustments. The temperature control accuracy can reach ±0.5℃, which greatly reduces labor intensity and improves production efficiency.

[0031] (4) The present invention adopts a three-stage gradient cooling molding technology, which can automatically adjust the temperature and flow rate of the cooling medium in each stage according to the material extrusion temperature, so that the material is cooled slowly and evenly, effectively reducing the internal stress inside the product, avoiding defects such as cracking and deformation, and significantly improving the electrical insulation performance and mechanical strength of the product.

[0032] (5) This invention has comprehensive real-time material status detection function and fault self-diagnosis function, which can monitor the equipment operating status in real time, detect and handle abnormal situations in a timely manner, ensure equipment and production safety, and improve the product qualification rate to over 99.5%.

The adaptive PID control module 4 has a built-in material characteristic database, which stores the optimal temperature curves and plasticizing parameters of more than 10 commonly used insulating materials such as polyethylene insulating material, polyvinyl chloride insulating material, and cross-linked polyethylene insulating material. At the same time, it has a built-in ambient temperature compensation algorithm, which can automatically correct the temperature control setpoints of each segment according to the ambient temperature detected by the ambient temperature sensor installed near the equipment, with a correction coefficient of 0.05℃ / ℃.

[0048] The human-machine interface module 6 uses a 10-inch color touch screen and is connected to the adaptive PID control module 4 via Ethernet. It can display operating parameters such as temperature, pressure, screw speed, and torque in real time. It supports the setting, modification, and storage of process parameters, can store at least 1,000 sets of production data, and can export data via USB interface.

[0049] The working process of this embodiment is as follows:

[0050] Production Preparation: First, select the grade of insulation material to be produced on the human-machine interface module 6. In this embodiment, cross-linked polyethylene insulation material is used as an example. The adaptive PID control module 4 automatically loads the optimal process parameters of the insulation material grade from the material characteristic database: the temperature of the feeding section 11 is 120℃, the temperature of the plasticizing section 12 is 160℃, the temperature of the homogenizing section 13 is 180℃, the temperature of the extrusion section 14 is 175℃, and the screw speed is 60rpm. At the same time, the ambient temperature sensor detects that the current ambient temperature is 25℃. The adaptive PID control module 4 automatically corrects the temperature setpoints of each section according to the ambient temperature compensation algorithm to: feeding section 11 is 121℃, plasticizing section 12 is 161℃, homogenizing section 13 is 181℃, and extrusion section 14 is 176℃.

[0051] Preheating stage: The adaptive PID control module 4 controls each heating unit of the multi-segment collaborative temperature control module 2 to start heating, while the material status real-time detection module 3 detects the material temperature of each segment in real time; when the temperature of each segment reaches the set value, the system automatically maintains the temperature for 30 minutes to ensure uniform temperature of the barrel and screw.

[0052] Feeding and extrusion: Start the extruder drive motor, the screw starts to rotate, and feeds the cross-linked polyethylene insulation material in the hopper into the barrel; under the conveying and shearing action of the screw, the material passes through the feeding section 11, plasticizing section 12, homogenizing section 13 and extrusion section 14 in sequence, and gradually melts and plasticizes.

[0053] Dynamic temperature control: During the extrusion process, the six built-in temperature sensors of the material status real-time detection module 3 detect the actual temperature of the material at different positions inside the screw in real time and transmit the detection data to the adaptive PID control module 4; the adaptive PID control module 4 compares the actual temperature with the set temperature and dynamically adjusts the power of each heating unit and cooling unit according to the temperature difference between two adjacent sections using an adaptive PID algorithm.

[0054] For example, when the material temperature in the middle of the plasticizing section 12 is detected to be 2°C higher than the set value, the adaptive PID control module 4 will automatically reduce the power of the second heating unit 22 and increase the cooling water flow of the second cooling unit 26 at the same time, so that the temperature of the plasticizing section 12 can be quickly restored to the set value. At the same time, the adaptive PID control module 4 will also fine-tune the power of the third heating unit 23 according to the temperature difference between the outlet of the plasticizing section 12 and the inlet of the homogenizing section 13, to ensure that the temperature transition of the material between the two sections is smooth and to avoid sudden temperature changes.

[0055] In addition, the adaptive PID control module 4 will dynamically adjust the screw speed based on the data detected by the pressure sensor and torque sensor. When the screw torque is detected to be too high, it indicates that the material is not sufficiently plasticized. The system will automatically reduce the screw speed and appropriately increase the temperature of the plasticizing section 12. When the pressure of the extrusion section 14 is detected to be too low, it indicates that the material is over-plasticized. The system will automatically increase the screw speed and appropriately decrease the temperature of the homogenizing section 13.

[0056] Gradient cooling molding: After the molten and plasticized insulating material is extruded from the extrusion section 14, it enters the gradient cooling molding module 5. The adaptive PID control module 4 automatically adjusts the temperature and flow rate of the cooling medium in each section of the gradient cooling molding module 5 according to the temperature of the extruded material detected by the sixth temperature sensor 36.

[0057] In this embodiment, the temperature of the extruded material is 175°C. The adaptive PID control module 4 automatically sets the cooling medium temperature of the first cooling section 51 to 140°C, the cooling medium temperature of the second cooling section 52 to 110°C, and the cooling medium temperature of the third cooling section 53 to 25°C. At the same time, the cooling water flow rate of each section is automatically adjusted according to the extrusion speed of the material: the flow rate of the first cooling section 51 is 6L / min, the flow rate of the second cooling section 52 is 8L / min, and the flow rate of the third cooling section 53 is 10L / min.

[0058] The insulating material passes through three cooling sections in sequence, where the temperature gradually decreases and it is slowly and evenly cooled and shaped, effectively avoiding internal stress caused by excessively rapid cooling.

[0059] Production monitoring and fault diagnosis: Throughout the production process, the human-machine interface module 6 displays various operating parameters of the equipment in real time, allowing operators to monitor the production status at any time. The adaptive PID control module 4 continuously monitors the data from each sensor. When abnormal temperature (e.g., temperature exceeding the set value ±5℃), abnormal pressure (e.g., pressure exceeding 40MPa), or abnormal torque (e.g., torque exceeding 400N・m) is detected, an audible and visual alarm signal will be automatically issued, and corresponding protective measures will be taken according to the abnormal situation. For example, when the temperature of the extrusion section 14 is detected to exceed 185℃, the system will automatically stop heating of all heating units and simultaneously increase the cooling water flow of each cooling unit. Production will resume after the temperature returns to normal.

[0060] This embodiment achieves dynamic and precise temperature control in the insulation material production process by employing technologies such as built-in temperature sensor array, multi-segment collaborative temperature control, adaptive PID control, and gradient cooling molding. Actual production testing shows that the temperature control accuracy of this equipment can reach ±0.5℃, the volume resistivity of the product is increased by more than 15%, the tensile strength is increased by more than 10%, and the product qualification rate is increased from 95% to 99.6%, achieving significant economic and social benefits.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
