The 75-type rubber extruder is a key piece of equipment widely used in the rubber products manufacturing field. It is mainly used to plasticize rubber raw materials through heating, shearing and pressurizing, and continuously extrude them into specific shapes through molds. This equipment plays a significant role in multiple industries such as tire manufacturing, sealing strip production, wire and cable coating, and hose manufacturing.
In the naming of the 75-type rubber extruder, “75” usually refers to the diameter of the screw being 75 millimeters. This parameter directly determines the production capacity and application scope of the equipment. Generally speaking, the larger the diameter of the screw, the more rubber can be extruded per unit time, which is suitable for large-scale production needs. The 75-type equipment has good applicability in medium and small-sized production lines, meeting the requirements of production efficiency while also having high flexibility and operational convenience.
This equipment is mainly composed of a transmission system, a heating and cooling system, a screw barrel assembly, a mold adjustment device, and a control system, etc. Among them, the design of the screw is particularly crucial. It not only affects the plasticizing effect of rubber but also determines the density and uniformity of the extruded products. Modern 75-type rubber extruders mostly adopt screws made of high-performance alloy steel, which have good wear resistance and corrosion resistance and can meet the requirements of long-term continuous operation.
In addition, the 75-type rubber extruder is usually equipped with advanced temperature control systems and pressure control systems to ensure that the rubber maintains stable physical properties during the extrusion process. Some high-end models are also equipped with PLC control systems to achieve automated control of the entire extrusion process, thereby improving production efficiency and the consistency of product quality.
In practical applications, the 75-type rubber extruder can be equipped with molds of different shapes according to the product requirements, thus producing rubber products with various cross-sectional shapes, such as circular, rectangular, and irregular sealing strips. Operators can adjust the temperature, pressure, and extrusion speed according to the process requirements to achieve the best molding effect.
Overall, the 75-type rubber extruder has become an indispensable important equipment in the rubber processing industry due to its compact structure, simple operation, and strong adaptability. With the development of automation and intelligent technology, the functions and performance of this equipment are constantly improving, providing a strong guarantee for the high-quality and high-efficiency production of rubber products.
