[0002] A screw extruder is a device used to deform raw materials into desired shapes by extruding them through a screw. It is commonly used in industries such as plastics, rubber, food, and chemicals. It can extrude raw materials into sheets, tubes, rods, or other shapes. The working principle of a screw extruder is that a rotating screw pushes the raw material from the feed port to the discharge port. The control of pressure and temperature can affect the quality and shape of the final product. Screw extruders play an important role in industrial production, helping manufacturers improve production efficiency and product quality.
[0003] However, existing screw extruders directly feed raw materials while simultaneously stirring and heating them. This uneven feeding, stirring, and heating leads to uneven distribution of the raw materials during the extrusion process, which in turn affects the quality of the final product. Utility Model Content

[0015] Beneficial effects:
[0016] 1. The system comprises a feeding hopper, heating plate, temperature controller, transmission gears, stirring shaft, steering gear, stirring rod, heating rod, handheld component, and insulation plate. The movement of the stirring shaft and rod effectively mixes the raw materials in the feeding hopper, ensuring uniform distribution of components and stable product quality. Mechanical mixing via the stirring rod saves energy and reduces production costs compared to manual mixing or other methods. The temperature controller precisely monitors and controls the temperature of the heating rod, ensuring the uniformly mixed raw materials are heated within a suitable temperature range, preventing overheating or undercooling from affecting product quality and ensuring uniform heating. The insulation plate provides additional insulation to prevent heat loss, stabilizing the heating plate temperature and preventing internal temperatures from affecting motor and gear operation. The handheld component on top of the heating rod facilitates operator inspection and maintenance, improving operational safety, reducing downtime, and facilitating heating position adjustments. These advantages contribute to ensuring normal operation, improving production efficiency and quality, simplifying maintenance, and reducing maintenance costs.
[0017] 2. Through the arrangement of the rotating shaft, nested parts, grooves, and stirring blades, different shapes and densities of the stirring blades can generate different stirring and shearing forces, promoting better mixing of raw materials. Through continuous stirring, different components can be evenly dispersed and mixed, improving the mixing effect and product uniformity. The movement of the stirring blades can make the heat from the heating plate more evenly transferred to the raw materials, improving energy utilization efficiency and reducing energy waste. The nested connection of the grooves and nested parts can ensure a stable connection between the stirring blades and the rotating shaft, preventing loosening or detachment. This can improve the stability and reliability of the stirring blades and ensure normal operation. Attached Figure Description
