New Compound Rubber Mixing And Extruder Replaces Traditional Rubber Mixing Mill

New Compound Rubber Mixing And Extruder Replaces Traditional Rubber Mixing Mill
Product introduction:
The rubber mixing line extruder is a key equipment in the rubber mixing production line, with the following characteristics:
1. Structural composition:
- Screw assembly:
- Material and process: The screw is usually made of high-quality alloy steel. After special heat treatment and surface treatment process, it has high hardness, strength and wear resistance, and can withstand the huge friction and shear force in the rubber mixing process. For example, some screws will be nitrided to improve surface hardness and corrosion resistance.
- Type and design: There are various types of screws, including single screw, twin screw and multi-screw. Different types of screws are suitable for different rubber mixing needs. The single-screw extruder has a simple structure and low cost, which is suitable for some simple rubber mixing and extrusion operations; the twin-screw extruder has better mixing effect and extrusion stability, and can achieve efficient mixing and extrusion of rubber; the multi-screw extruder has advantages in the mixing of complex rubber formulas and the production of high-performance rubber products.
- Barrel:
- Material and structure: The barrel is generally made of high-quality steel, and the inner wall is finely processed to ensure good finish and dimensional accuracy. The barrel is usually equipped with heating and cooling devices. The heating methods include electric heating, steam heating or thermal oil heating, and the cooling methods include water cooling or air cooling. In this way, the temperature in the barrel can be accurately controlled according to the process requirements of rubber mixing, ensuring that the rubber is mixed and extruded within a suitable temperature range.
- Feeding port: The design of the feeding port must ensure that the rubber raw materials can enter the barrel smoothly, and must be able to control the feeding speed and amount. Some advanced extruders are also equipped with an automatic feeding system, which can automatically adjust the feeding speed according to the set process parameters to improve the degree of automation and production efficiency of production.
- Die and mold: The die is the part that connects the barrel and the mold. Its function is to evenly transport the mixed rubber in the barrel to the mold. The design of the die must ensure smooth flow of rubber to avoid blockage or uneven pressure. The mold is designed according to the shape and size requirements of the rubber product, which determines the shape and dimensional accuracy of the extruded rubber product.
2. Working principle:
- Mixing process: After the rubber raw material enters the barrel from the feed port, it moves forward under the rotation of the screw. The rotation of the screw will produce shear, extrusion and stretching effects on the rubber raw material, so that the rubber and various compounding agents (such as fillers, plasticizers, vulcanizers, etc.) are fully mixed to achieve rubber mixing. During the mixing process, the temperature and pressure in the barrel will change continuously, and need to be controlled by heating and cooling devices and screw speed adjustment to ensure the mixing effect and quality of the rubber.
- Extrusion process: The mixed rubber enters the die under the push of the screw, and then is extruded through the mold to form a rubber product of the desired shape and size. During the extrusion process, the pressure in the die and the mold must be kept stable to ensure the dimensional accuracy and surface quality of the rubber product.
3. Performance advantages:
- Efficient mixing capacity: It can quickly and evenly mix rubber with various compounding agents, greatly improving the mixing efficiency and quality of rubber. Compared with traditional mixing equipment such as open mills, extruders have better mixing effects and can meet the production requirements of high-performance rubber products.
- Precise extrusion control: The shape, size and weight of extruded rubber products can be precisely controlled to ensure the consistency and stability of the products. By adjusting parameters such as the screw speed, barrel temperature and pressure, the extrusion process can be precisely controlled to meet the production requirements of different rubber products.
- Continuous production capacity: It can achieve continuous production and greatly improve production efficiency. Compared with intermittent production equipment, extruders can run continuously without interruption, reducing the number of equipment starts and stops and the pause time in production, improving production efficiency and equipment utilization.
- Good adaptability: It is suitable for mixing and extruding rubber of various types and formulations, and has a wide range of applications. Whether it is natural rubber, synthetic rubber or rubber composite materials, they can be mixed and extruded through extruders to produce various rubber products such as rubber tubes, rubber sheets, rubber strips, rubber seals, etc.
4. Operation and maintenance:
- Easy operation: Modern rubber mixing line extruders are usually equipped with advanced automatic control systems. Operators only need to enter relevant process parameters on the control panel, and the equipment can run automatically. The operation interface is friendly, easy to operate and master, and reduces the technical requirements for operators.
- Easy maintenance: The structural design of the equipment is reasonable, and the connection and disassembly between the components are convenient, which is convenient for daily maintenance and maintenance. For example, key components such as screws and barrels can be easily disassembled and installed for regular inspection, cleaning and maintenance. At the same time, the replacement of equipment wearing parts such as seals and bearings is also relatively convenient, reducing the maintenance time and cost of the equipment.
