Description

Technical Field

[0001] The utility model belongs to the technical field of temperature control, and in particular relates to an energy-saving control system for a temperature control device of a composite extruded wire. Background Art

[0002] In the tire production process, semi-finished product processing, such as the tread and sidewall composite extrusion lines, as well as the calendering and plasticizing extruders, primarily utilize electric heating and temperature control equipment. Using softened water as the temperature control medium and circulating cooling water as the cooling medium, they maintain constant temperature control for the screw, feeding, plasticizing, extrusion, and the upper, middle, and lower mold bodies of the die. By setting different process temperatures in different locations, the processing requirements of the semi-finished product are met. The temperature control devices utilize high-power electric heaters, and effective management of the temperature control and heating system is an effective measure for factories to conserve electricity.

[0003] In the temperature control device, when the temperature measuring element detects the temperature of each section of the cold feed extruder and converts it into an electrical signal, it is input into the temperature display and regulator. The actual temperature is displayed on the measurement display part, and the deviation value is compared with the set temperature on the regulation part. The regulator calculates according to certain mathematical rules and outputs a signal to control the heating and cooling systems.

[0004] The commonly used temperature control equipment system of a certain company's extrusion line currently includes 1 heat exchanger; 2 circulating water pump; 3 heater; 4 exhaust valve; 5 temperature measuring platinum thermal resistor; 6 safety valve;

[0005] During operation, softened water is pumped from the outlet of the circulating water pump into a heating tank for heating. It then passes through a degassing tank and is sent to the extruder's heated working unit, heating the unit. The softened water returning from the working unit is filtered, enters a heat exchanger, and then enters the inlet of the circulating water pump, forming a closed water circulation loop. An extruder is controlled by independent temperature control circuits for the screw, feeding, plasticizing, extrusion, and die head. Each heating power ranges from 6kW to 15kW. A platinum RTD installed in the return pipe converts the measured temperature into an electrical signal, which is input to the temperature control instrument. The temperature control instrument uses the deviation between the measured value and the set value to adjust the system's PID control to control heating or cooling. When the softened water returns above the set temperature and requires cooling, the solenoid valve in the heat exchanger's cooling circuit opens, allowing the cooling water to exchange heat with the softened water through the heat exchanger, thereby cooling the softened water. This unit forms a closed-loop system until the set temperature is reached, maintaining the temperature measurement within the set value's tolerance.

[0006] However, temperature control equipment with high power consumption should have abnormal conduction problems in the unit heating circuit, but currently only the power meter is installed on the main switch, which makes it difficult to point to the specific unit location. Utility Model Content

[0007] The purpose of the present utility model is to provide an energy-saving control system for a temperature control device of a composite extruded wire, which collects and analyzes the electric heating time of the temperature control device, actively warns and controls abnormal circuits, reduces power consumption, and solves the problems raised in the above-mentioned background technology.

[0008] In order to achieve the above-mentioned object, the utility model adopts the following technical solutions: the energy-saving control system of the composite extruded wire temperature control device includes a main controller with the function of displaying alarm information, a solid-state relay and a register D;

[0009] The total system operation time counter starts counting with 1ms pulses and stores the total time in register D. When the heating starts, the solid-state relay DC12V is turned on, and the voltage signal is simultaneously transmitted to the PLC to count at a high speed with 1ms pulses and store the heating on-time in register D. The data is archived once every hour for easy comparison on the touch screen. A total of no less than 24 hours of on-time data can be archived.

[0010] The data calculation formula is:

[0011] K heating conduction rate = D heating conduction time / D total time;

[0012] By checking the conductivity and comparing it with the conductivity under normal conditions, it is possible to find out the channels with mutations, that is, the channels with abnormal heating.

[0013] Preferably, the main controller model is FX5U PLC.

[0014] Preferably, the main controller has a built-in warning information management unit, and the warning information is displayed through the touch screen of the main controller.

[0015] Preferably, the warning information management unit includes a device classification module, a real-time proportion display unit, and an abnormal proportion warning unit.

[0016] Preferably, the equipment classification module is used to classify, manage and display different types of equipment according to equipment usage type and process operation sequence rules.

[0017] Preferably, the real-time proportion unit is used to realize the real-time proportion of each device, and cooperates with the abnormal proportion warning unit to perform color marking warnings on abnormal proportion data.

[0018] In summary, compared with the existing technology, the beneficial effects of the present invention are: the present application relates to an energy-saving control system for temperature control equipment of semi-finished treads and sidewall composite extrusion lines in tire factories, which collects and analyzes the electric heating time of the temperature control device, actively warns and controls abnormal circuits, and reduces electricity consumption.
