The screw needs to maintain a constant temperature during operation to ensure the plasticization quality of the plastic raw materials. At present, the commonly used screw heating methods mainly include electric heating and oil heating. However, these heating methods have some problems. The traditional heating system lacks fine temperature adjustment ability, resulting in inaccurate temperature control of the extruder screw and affecting the plasticization effect of the plastic raw materials. Since the heating power cannot be adjusted according to actual needs, the traditional system often has high energy consumption, which is not conducive to cost control and energy conservation. When the temperature changes, the response speed of the traditional system is slow, and it is difficult to quickly adjust to the ideal working temperature, affecting production efficiency and product quality.

[0056] It can be understood that when adjusting the coolant flow rate of the cooling channel 3 and the temperature of the heating element 2, the present utility model adopts a dynamic feedback mechanism. By recording the temperature change ΔT of the heating tile and the time interval Δt between the two temperature readings, the present utility model calculates the temperature change rate P of the heating tile. This change rate reflects the fluctuation speed of the heating tile temperature and is an important indicator for measuring the temperature control effect.

The temperature control system of the present utility model can quickly respond to the temperature change of the extruder screw, timely adjust the heating and cooling parameters, and ensure the stability and efficiency of temperature control. Since the present utility model can provide stable and precise temperature control, it can speed up the production process, improve the working efficiency of the extruder screw, and thus enhance the overall production efficiency. The design of the present utility model takes into account safety factors, adopts reliable heating and cooling technologies, reduces potential safety risks such as electric shock or oil leakage, and provides a safer working environment for operators. By optimizing the heating and cooling processes, the present utility model helps to reduce the wear of the extruder screw, extend the service life of the equipment, and reduce maintenance costs. By precisely controlling the temperature of the extruder screw, the present utility model helps to improve the quality of the final plastic product and meet the high-standard industrial application requirements.

[0058] In this preferred embodiment, adjusting the coolant flow rate of the cooling channel 3 according to the temperature change rate P specifically includes:

[0059] The temperature change rate of the heating tile is P, and the preset temperature change rates of the first heating tile P1, the second heating tile P2, the third heating tile P3, the fourth heating tile P4, and the fifth heating tile P5 are set, and P1 < P2 < P3 < P4 < P5; the coolant flow rates of the primary cooling channel V1, the secondary cooling channel V2, the tertiary cooling channel V3, the quaternary cooling channel V4, and the quinary cooling channel V5 are preset, and V1 < V2 < V3 < V4 < V5;

[0060] According to the magnitude relationship between the temperature change rate P of the heating tile and the preset temperature change rates of each heating tile, determine the coolant flow rate of the cooling channel;

[0061] When P ≤ P1, determine that the coolant flow rate of the cooling channel is the coolant flow rate V1 of the primary cooling channel;

[0062] When P1 < P ≤ P2, determine that the coolant flow rate of the cooling channel is the coolant flow rate V2 of the secondary cooling channel;

[0063] When P2 < P ≤ P3, determine that the coolant flow rate of the cooling channel is the coolant flow rate V3 of the tertiary cooling channel;

[0064] When P3 < P ≤ P4, determine that the coolant flow rate of the cooling channel is the coolant flow rate V4 of the quaternary cooling channel;

[0065] When P4 < P ≤ P5, determine that the coolant flow rate of the cooling channel is the coolant flow rate V5 of the quinary cooling channel.

[0066] It can be understood that the present utility model realizes the hierarchical control of the coolant flow rate of the cooling channel 3 by comparing the temperature change rate P of the heating tile with the preset temperature change rates P1 to P5 of different levels of heating tiles. This control strategy allows the system to dynamically adjust the coolant flow rate according to the actual temperature change rate, thereby precisely controlling the temperature of the heating tile. Specifically, when the actually measured temperature change rate P of the heating tile is less than or equal to the first preset temperature change rate P1, the system will select the lowest coolant flow rate V1 of the primary cooling channel 3. If P is between P1 and the second preset temperature change rate P2, the system will increase the coolant flow rate to the coolant flow rate V2 of the secondary cooling channel 3. And so on, as P increases, the coolant flow rate will be increased to V3, V4, and V5 in sequence, corresponding to higher temperature change rate levels. This hierarchical control method enables the cooling system to more flexibly adapt to the temperature change of the heating tile, ensuring the optimal cooling effect under different working conditions. In this way, the present utility model not only improves the accuracy of temperature control, but also can effectively reduce energy consumption while ensuring the heating efficiency, improving the operating efficiency and overall economy of the extruder screw.

[0067] In this preferred embodiment, adjusting the temperature of the heating element 2 according to the temperature change rate P specifically includes:

[0068] The temperature change rate of the heating tile is P, and the preset first heating tile temperature change rate P1, second heating tile temperature change rate P2, third heating tile temperature change rate P3, fourth heating tile temperature change rate P4, and fifth heating tile temperature change rate P5 are set, and P1 < P2 < P3 < P4 < P5; the preset temperatures of the first-level heating element N1, second-level heating element N2, third-level heating element N3, fourth-level heating element N4, and fifth-level heating element N5 are set; and N1 < N2 < N3 < N4 < N5;

[0069] Determine the temperature of the heating element according to the magnitude relationship between the temperature change rate P of the heating tile and each preset heating tile temperature change rate;

[0070] When P ≤ P1, determine that the temperature of the heating element is the temperature N1 of the first-level heating element;

[0071] When P1 < P ≤ P2, determine that the temperature of the heating element is the temperature N2 of the second-level heating element;

[0072] When P2 < P ≤ P3, determine that the temperature of the heating element is the temperature N3 of the third-level heating element;

[0073] When P3 < P ≤ P4, determine that the temperature of the heating element is the temperature N4 of the fourth-level heating element;

[0074] When P4 < P ≤ P5, determine that the temperature of the heating element is the temperature N5 of the fifth-level heating element.

[0075] It can be understood that the present utility model realizes the intelligent adjustment of the temperature of the heating element 2 by monitoring the temperature change rate P of the heating tile and comparing it with the preset temperature change rate levels P1 to P5. This method ensures that the temperature of the heating element 2 can match the actual working requirements of the heating tile, thereby improving the adaptability and efficiency of the temperature control system. Specifically, when the temperature change rate P of the heating tile is within the preset minimum change rate P1 range, the system will select the lowest temperature setting N1 to control the heating element 2. If P exceeds P1 but does not exceed P2, the system will increase the temperature setting of the heating element 2 to N2, and so on. As P increases, the temperature setting of the heating element 2 will be sequentially increased to N3, N4, and N5, corresponding to higher temperature change rate levels. This hierarchical adjustment strategy enables the heating system to quickly respond to the actual temperature change of the heating tile, not only ensuring the stability of the heating process but also helping to prevent the decrease in the working efficiency of the extruder screw due to temperature fluctuations. In addition, by precisely controlling the temperature of the heating element 2, the present utility model can also effectively reduce energy consumption, extend the service life of the equipment, and improve the quality and reliability of the extrusion molding process.

[0076] In this way, by real-time monitoring the temperature change rate of the heating tile and comparing it with the preset different levels of temperature change rates, the precise control of the temperature of the heating element is achieved. This hierarchical control strategy enables the cooling system to dynamically adjust the flow rate of the coolant according to the actual temperature change of the heating tile, thereby ensuring the optimal cooling effect under different working conditions. At the same time, by precisely controlling the temperature of the heating element, the present utility model not only improves the accuracy of temperature control but also effectively reduces energy consumption while ensuring the heating efficiency, improves the operating efficiency of the extruder screw and the overall economy. This intelligent temperature control method not only improves the adaptability and efficiency of the temperature control system but also helps to prevent the decrease in the working efficiency of the extruder screw due to temperature fluctuations, thereby improving the quality and reliability of the extrusion molding process.

[0077] In this preferred embodiment, the cooling channels 3 are arranged in a multi-loop structure inside the base body 1.

[0078] It can be understood that by arranging the multi-loop structure cooling channels 3 inside the base body 1 in the present utility model, the flow path of the coolant is increased, thereby improving the cooling efficiency and heat exchange effect. This design of the cooling channels 3 helps to reduce the temperature of the heating tile and ensure the stability of the extruder screw in a high-temperature working environment.

[0079] In this preferred embodiment, reinforcing ribs are further arranged inside the base body. The reinforcing ribs are fixed inside the base body and are adjacent to the heating element.

[0080] It is understandable that in the preferred embodiments of the present utility model, the reinforcing ribs provided inside the base are intended to improve the structural strength and stability of the heating tile. These reinforcing ribs are fixed inside the base and are located near the heating element. They can effectively support the heating element and prevent deformation or damage under high-temperature working conditions. This structural design not only enhances the durability of the heating tile but also ensures the uniform heating effect of the heating element, thereby improving the performance and reliability of the entire extruder screw heating system. By adding reinforcing ribs inside the heating tile, the present utility model further optimizes the structure of the heating tile, enabling it to better adapt to high-temperature and high-load working environments and extending the service life of the equipment.
