Kneader And Single Screw Electric Wire Extrusion Line for HFFR Material Application

Specification:

Description1:

This machine is used for insulating or sheathing LSZH cables. It features a specialized screw for LSZH material, and the compression ratio is strictly controlled to ensure a smooth extrusion process. It also has a heating and cooling system tailored to the needs of the machine to ensure the optimal operating temperature. Additionally, there is a user-friendly PLC control panel for quick adjustments to production configuration and settings.


Feature:

Using a specialized screw for LSZH material and strictly controlling the compression ratio based on the material's unique characteristics.
Ensuring the tensile strength, elongation, and surface finish of LSZH material by choosing a squeezing mold for insulation and a semi-squeezing mold for sheathing.

The entire line is controlled by PLC with a human-machine interaction interface, using digital control technology and PLC programs for a reliable and flexible control system.

The cooling system of the entire line is crucial for extruding LSZH material, therefore, a special heating and cooling temperature control system is adopted.


Description2:

A kneader and single screw electric wire extrusion line for HFFR (Halogen-Free Flame Retardant) material application refers to a production line specifically designed to extrude electric wires using a kneading machine and a single screw extruder, with a focus on using HFFR materials. Here's a description of the key components and features:

1. Kneader Machine:

   • The kneader machine is used to mix and knead the HFFR material. It typically consists of a cylindrical chamber with intermeshing rotor blades.
   • The kneader ensures thorough dispersion and uniform distribution of additives and fillers in the HFFR compound. This process helps achieve consistent flame-retardant properties and electrical insulation performance.
   • The machine may feature variable speed control, temperature control systems, and monitoring capabilities to optimize the kneading process.

2. Single Screw Extruder:

   • The single screw extruder is a key component of the extrusion line. It receives the kneaded HFFR compound from the kneader and further melts and processes the material.
   • The extruder consists of a heated barrel with a single rotating screw. The screw conveys and compresses the material, generating heat through mechanical and electrical energy input.
   • The extruder may feature a control system for temperature, screw speed, and pressure, ensuring precise control over the extrusion process.
   • It may also include a degassing system to remove volatiles and gases generated during the melting and extrusion of the HFFR material.

3. Die Design:

   • The extrusion line incorporates a die specifically designed for electric wire production using HFFR material. The die shapes and sizes the extruded wire to the desired dimensions.
   • The die design ensures uniformity and accuracy in the wire's cross-sectional shape and dimensions, important for achieving consistent electrical properties and insulation performance.

4. Cooling and Sizing:

   • After extrusion, the wire passes through a cooling and sizing system. This system consists of water baths or air cooling units that help solidify and cool the extruded wire.
   • Sizing tools are used to precisely control the wire's diameter and shape, ensuring compliance with specifications and standards.

5. Haul-off Unit and Cutting System:

   • The extrusion line includes a haul-off unit, also known as a caterpillar unit, which pulls the extruded wire at a controlled speed. This maintains consistent dimensions and tension during the production process.
   • A cutting system is employed to cut the extruded wire into desired lengths. It may include a blade or a guillotine cutter for accurate and clean cuts.

6. Control System and Automation:

   • The extrusion line features a control system that integrates and monitors the various components and processes. It enables precise control of parameters such as temperature, speed, and pressure.
   • Automation features, such as touchscreen interfaces and PLC technology, enhance productivity and quality control by automating certain tasks and providing real-time monitoring and data logging capabilities.

7. Safety Features:

   • Safety features are implemented throughout the extrusion line to ensure a safe working environment. These may include emergency stop buttons, safety interlocks, and guarding.

8. Maintenance and Serviceability:

   • The extrusion line is designed for ease of maintenance and serviceability. It may include features such as quick-change components, easy access for cleaning and maintenance tasks, and diagnostic systems to identify and troubleshoot issues.

It's worth noting that the specific features and configurations of a kneader and single screw electric wire extrusion line for HFFR material application can vary depending on the manufacturer and the specific requirements of the wire production process. It's advisable to consult with the manufacturer or supplier to confirm the available features and specifications that meet your specific needs.
