Description

Technical Field

[0001] This utility model relates to the field of temperature control technology for coating equipment, specifically to a multi-channel online temperature monitoring and recording system for PTFE high-temperature tape coating equipment. Background Technology

[0002] Polytetrafluoroethylene (PTFE) high-temperature tapes possess excellent high-temperature resistance, chemical corrosion resistance, and superior insulation properties, making them widely used in high-end manufacturing fields such as electronics, electrical appliances, and aerospace for insulation coating, baking tray lining, and welding protection. In its production process, the high-temperature curing process after coating is the core step that determines the tape's final physical properties, adhesive strength, and appearance quality. This process is typically carried out in continuously operating tunnel-type drying equipment, requiring extremely precise and stable temperature control within the drying tunnel. Traditional temperature control often relies on a single temperature detection point at the inlet or outlet of the drying tunnel, employing simple "on-off" or PID fixed-frequency exhaust control. For multi-channel drying tunnels that are tens of meters long and interconnected, this single-point detection cannot reflect the true temperature field distribution inside the tunnel, especially in the middle section. This leads to discrepancies between the preset and actual temperatures. Changes in ambient temperature and material conveying speed can disrupt the thermal balance. Fixed-frequency exhaust control has a slow response, making it difficult to maintain the constant temperature environment required by the process. This results in uneven curing of PTFE tape, affecting product consistency, and exhibiting low temperature control accuracy and lag.

[0003] Therefore, it is necessary to invent a multi-channel online temperature monitoring and recording system for PTFE high-temperature tape coating equipment to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-channel online temperature monitoring and recording system for PTFE high-temperature tape coating equipment. This system solves the problems of single-point detection failing to reflect the internal temperature of the drying tunnel during actual use, resulting in uneven curing of PTFE tape, affecting product consistency, low temperature control accuracy, and delayed response.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-channel online temperature monitoring and recording system for PTFE high-temperature tape coating equipment includes a platform. The top of the platform supports multiple interconnected tunnel-type drying tunnels. An exhaust vent is provided in the middle of the interconnected tunnel-type drying tunnels. A conveying end for conveying materials into the tunnel-type drying tunnels is provided on one side of the platform, and a winding end for recycling materials is provided at the other end of the platform. A temperature sensor for real-time monitoring of the drying tunnel temperature is provided inside each tunnel-type drying tunnel. An intelligent control system electrically connected to the temperature sensor and the exhaust vent is formed.

[0006] As a preferred embodiment of this utility model, the intelligent control system includes a temperature control mechanism, which is used to set the preset temperature required by the process, receive and display the temperature of each temperature sensor, and control the exhaust rate of the exhaust vent.

[0007] In a preferred embodiment of this utility model, the exhaust port is connected to a variable frequency fan, and the temperature control mechanism changes the exhaust rate by adjusting the operating frequency of the variable frequency fan.

[0008] As a preferred embodiment of this utility model, the number of interconnected tunnel-type drying channels is 5 to 8 sections.

[0009] As a preferred embodiment of this utility model, the bottom end of the platform is provided with multiple columns, and the bottom end of the platform is provided with a set of tunnel-type drying tunnels, each of which is hinged with a sealed side door.

[0010] As a preferred embodiment of this utility model, the intelligent control system further includes an alarm module that triggers a critical point alarm when the real-time temperature data is lower than a preset low temperature threshold or higher than a preset over-temperature threshold.

[0011] As a preferred embodiment of the present invention, the intelligent control system further includes a data recording module, which is configured to continuously record and store temperature data from the temperature sensor and the corresponding timestamp.

[0012] As a preferred embodiment of this utility model, the intelligent control system further includes a communication module for remote monitoring and data acquisition, used to upload process-related temperature data to a cloud server.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: In this invention, a corresponding temperature sensor is installed in each tunnel-type drying tunnel, and relevant data is displayed and recorded in a timely manner through a temperature control mechanism. By controlling the frequency-modulated motor at the exhaust port, the temperature inside the tunnel-type drying tunnel is regulated, and the waste gas generated during the production process is treated. At the process level, by dynamically adjusting the exhaust volume, the thermal balance inside the drying tunnel is precisely maintained, ensuring that the PTFE tape completes the curing process in an optimal and stable temperature environment, thereby ensuring a high degree of consistency in the physical properties of the product. At the environmental safety level, this process can effectively discharge volatile substances and other process waste gases generated during the heating of the material and guide them to subsequent treatment devices. This not only prevents the accumulation of waste gas in the drying tunnel from potentially causing adverse effects on product quality, but also meets the requirements of environmentally friendly and safe production.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] This utility model provides, for example Figure 1 The system illustrates a multi-channel online temperature monitoring and recording system for a PTFE high-temperature tape coating equipment. It includes a platform 10, with multiple interconnected tunnel-type drying tunnels 3 supported at its top. Each tunnel-type drying tunnel 3 has an exhaust vent 7 in its center. One side of the platform 10 has a conveying end 1 for feeding material 6 into the tunnel-type drying tunnel 3, and the other end has a winding end 8 for collecting the material 6. Each tunnel-type drying tunnel 3 is equipped with a temperature sensor 4 for real-time temperature monitoring. The temperature sensor 4 and the exhaust vent 7 form an electrically connected intelligent control system. By installing temperature sensors inside each tunnel-type drying tunnel 3, the actual temperature at each point can be monitored and controlled online in real-time. This allows for precise understanding of the actual temperature at each point during production, timely control of the exhaust frequency of the exhaust vent 7 via a frequency-modulated motor, control of the temperature inside the drying tunnel, and simultaneous discharge of waste gas from the drying tunnel, thereby improving the product molding effect. Each tunnel-type drying tunnel is equipped with two or more temperature sensors for real-time monitoring of the drying tunnel temperature. The main unit in the temperature control mechanism 2 is a multi-channel online temperature detection and recording system, which is used to realize remote monitoring and data acquisition communication module, and is used to upload process-related temperature data to the cloud server.

[0018] The intelligent control system includes a temperature control mechanism 2, which is used to set the preset temperature required for the process, receive and display the temperatures of each temperature sensor 4, and control the exhaust rate of the exhaust vent 7. The temperature control mechanism 2 is used to preset the temperature inside the oven and display the actual temperature inside each group of ovens, improving the accuracy of temperature control.

[0019] The exhaust vent 7 is connected to a variable frequency fan, and the temperature control mechanism 2 changes the exhaust rate by adjusting the operating frequency of the variable frequency fan. When the real-time temperature data deviates from the preset temperature threshold, the temperature is adjusted to a reasonable range by regulating the variable frequency fan.

[0020] The number of interconnected tunnel-type drying tunnels is 5 to 8 sections.

[0021] The platform 10 has multiple columns 9 at its bottom end and a set of tunnel-type drying tunnels 3 at its bottom end. Each tunnel-type drying tunnel 3 has a sealed side door 5 hinged to one side. The sealed side doors 5 facilitate cleaning and maintenance of the tunnel-type drying tunnel 3. The columns 9 support the platform 10, which divides the workplace into upper and lower levels, facilitating product processing and equipment maintenance.

[0022] The intelligent control system also includes an alarm module that triggers a critical point alarm when the real-time temperature data is lower than a preset low-temperature threshold or higher than a preset over-temperature threshold. This ensures product consistency, prevents performance differences in PTFE high-temperature tape due to temperature anomalies, and enables timely detection and resolution of equipment malfunctions.

[0023] The intelligent control system also includes a data recording module, configured to continuously record and store temperature data and corresponding timestamps from temperature sensor 4. The system automatically records all temperature data and corresponding timestamps, allowing for quick and accurate tracing of the entire temperature history during the production of the tape roll in the event of a product quality problem, thus enabling precise responsibility identification and root cause analysis.

[0024] The intelligent control system also includes a communication module for remote monitoring and data acquisition, used to upload process-related temperature data to a cloud server. This data upload function allows managers to monitor production status in real time from their offices or via mobile phones, achieving remote and transparent management.

[0025] This invention, by installing corresponding temperature sensors 4 in each group of tunnel-type drying tunnels 3, and displaying and recording relevant data in a timely manner through a temperature control mechanism 2, and controlling the frequency-modulated motor at the exhaust port 7, achieves temperature regulation inside the tunnel-type drying tunnel 3 and treats the waste gas generated during the production process. At the process level, by dynamically adjusting the exhaust volume, the thermal balance inside the drying tunnel is precisely maintained, ensuring that the PTFE tape completes the curing process in an optimal and stable temperature environment, thereby guaranteeing a high degree of consistency in the physical properties of the product. At the environmental safety level, this process can effectively discharge volatile substances and other process waste gases generated during the heating of the material 6 and guide them to subsequent treatment devices, which not only prevents the accumulation of waste gas in the drying tunnel from potentially causing adverse effects on product quality, but also meets the requirements of environmentally friendly and safe production.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
