The rubber single screw extruder with a screw diameter of 75mm is introduced as follows:

- Working principle:
- The rubber material enters the extruder from the hopper and is transported forward along the inner wall of the barrel under the rotation of the screw. The rotation of the screw produces shearing, compression and stirring effects on the material, so that the material is gradually plasticized, melted, and forms a uniform melt.
- Under the push of the screw, the material is extruded through the head and the die to form the required shape of rubber products, such as rubber strips, rubber tubes, etc.
- Structural composition:
- Screw: It is the core component of the extruder with a diameter of 75mm. The screw usually has different pitches and groove depths to realize the functions of conveying, compressing and plasticizing the material.
- Barrel: It wraps the screw and provides space for plasticization and conveying of the material. The inner wall of the barrel is usually specially treated and has good wear resistance and corrosion resistance.
- Transmission device: It is used to drive the screw to rotate, usually composed of a motor, a reducer, a coupling, etc., to provide the required speed and torque for the screw.
- Feeding device: used to add rubber materials to the extruder, common ones include hoppers and feeders.
- Die and die: The die is a component connecting the barrel and the die, used to evenly distribute the plasticized material to the die. The die determines the shape and size of the extruded product.
- Temperature control device: heats or cools the barrel, screw and die to control the temperature of the material to ensure that the material is plasticized and extruded within the appropriate temperature range.
- Performance characteristics:
- Extrusion capacity: The screw diameter of 75mm determines that it has a certain extrusion capacity and can meet the needs of specific scale production. The extrusion volume per hour will vary depending on the type of rubber material, formula and process parameters.
- Plasticizing effect: Through reasonable screw design and parameter setting, the rubber material can be effectively sheared, compressed and stirred to fully plasticize the material and ensure the quality of the extruded product.
- Adaptability: It can be applied to the extrusion processing of a variety of rubber materials, such as natural rubber, synthetic rubber, etc. At the same time, for rubber materials of different hardness and viscosity, better extrusion effects can be achieved by adjusting process parameters.
- Stability: During operation, it can maintain a relatively stable extrusion state to ensure the dimensional accuracy and quality stability of the extruded products.
- Operation and maintenance: The operation is relatively simple, and trained operators can easily master the operation method of the equipment. At the same time, the maintenance of the equipment is relatively convenient, which is convenient for daily cleaning, lubrication and component inspection.
- Application areas:
- Rubber product production: It can be used to produce various rubber strips, rubber tubes, rubber sheets and other products, which are widely used in sealing, shock absorption, insulation and other parts in the automotive, construction, electronics, machinery and other industries.
- Rubber extrusion molding: In the rubber extrusion molding process, such as the extrusion of rubber profiles and the coating of rubber cables, the extruder can play an important role.
- Continuous production of rubber products: It is suitable for large-scale and continuous production of rubber products, which can improve production efficiency and reduce production costs.
