The high-quality mesh panel extruder temperature control and cooling system is a key link in the rubber processing process. Together, they ensure that the rubber material maintains an appropriate temperature during the extrusion process, thereby producing products of good quality. The following is a detailed discussion of the temperature control and cooling system of the high-quality mesh panel extruder.

I. The Importance of Temperature Control

Rubber is a heat-sensitive material, and its fluidity, plasticization degree and physical properties all change with temperature. During the rubber extrusion process, an appropriate temperature can endow the rubber compound with good fluidity, which is conducive to extrusion molding. Meanwhile, the control of temperature can also affect the curing degree of rubber. Both excessively high and low temperatures will have adverse effects on the physical properties of rubber. Therefore, correctly controlling the temperature of the extruder is important for determining the quality of rubber products.

Ii. Temperature Control Methods

The temperature control method of high-quality mesh panel extruder is generally to form a closed circuit for control in the sequence of measurement, regulation operation, target control, etc. That is, to accurately measure the temperature of the controlled object, identify the error between it and the specified temperature, modify the operation quantity, and maintain the temperature of the controlled object to a certain extent. The specific temperature control methods include pneumatic regulation and electric regulation.

Pneumatic regulation: In the pneumatic regulation temperature control device, the temperature measurement element detects the temperature of each section of the high-quality mesh panel extruder and converts it into an electrical signal, which is then input into the temperature display regulator. One signal is sent to the measurement display section to show the actual temperature, and the other signal is sent to the adjustment section and compared with the set temperature to obtain the deviation value. The regulator then outputs a signal to control the heating system and the cooling system after calculation according to the corresponding mathematical rules. When the measured temperature of the barrel deviates from the set temperature value, the pneumatic regulator issues a signal instruction based on the magnitude and nature of the deviation to control the opening degree of the pneumatic actuators in the heating system and cooling system, thereby achieving accurate temperature control.

Electric regulation: In the temperature control device of electric regulation, the on-off signal sent by the temperature regulator often has a proportional nature. When the measured temperature of the barrel is higher than a certain range of the set temperature value, the temperature regulator sends a signal to connect the power supply of the electric actuator controlling the cooling water system and cut off the power supply of the heating system at the same time, causing the temperature of the barrel to drop. When the temperature drops and falls below the set temperature by a certain range, the temperature regulator sends a signal to connect the power supply of the heating system and simultaneously cut off the power supply of the electric actuator that controls the cooling water system, causing the barrel temperature to rise. Through such repeated heating and cooling, the temperature value of the system tends to the set value, thereby achieving constant temperature control.

Iii. Cooling System

The cooling system of high-quality mesh panel extruder is mainly used to reduce the temperature of components such as the barrel, screw and mold, to prevent material degradation, equipment damage and decline in product quality caused by excessive temperature. The cooling system is usually composed of a cooling water circulation system and a cooling medium.

Cooling water circulation system: The cooling water circulation system delivers cooling water to various components of the extruder that require cooling, such as the barrel, screw, and mold, through a circulation pump. The cooling water flows inside the component, absorbs heat and then flows back to the water storage tank. It is cooled again through the cooler and then recycled again. This kind of system has the advantages of simple structure, low operation and low cost.

Cooling medium: The cooling medium can be water, oil or other liquids. When choosing a cooling medium, factors such as its thermal conductivity, chemical stability, stability and cost need to be taken into consideration. Water is a commonly used cooling medium because it has the advantages of high thermal conductivity, low cost and easy availability. However, in some special circumstances, such as when heating at a relatively high temperature is required, other cooling media may need to be adopted.

Iv. Optimization of Temperature Control and Cooling System

In order to improve the production rate and product quality of high-quality mesh panel extruder, it is necessary to optimize the temperature control and cooling system. Specific optimization measures include:

The adopted temperature control technologies: such as PID temperature control technology, fuzzy control technology and other control technologies are used to achieve accurate temperature control.

Optimize the design of the cooling system: such as increasing the number of cooling water channels, changing the layout of the cooling water channels, and raising the flow rate of the cooling medium, etc., to enhance the cooling effect.

Increase equipment maintenance: Regularly maintain and service the temperature control and cooling systems to ensure their normal operation and accurate temperature control.

To sum up, the temperature control and cooling system of high-quality mesh panel extruder is a key link in determining the quality of rubber products. By adopting temperature control technology, optimizing the design of the cooling system and increasing equipment maintenance, precise temperature control can be achieved, thereby enhancing production rate and product quality.
