Composite Strap Production Line

Product Description:

Composite Strap Production Line also called Polyester Fiber Flexible composite strap extruder machine line. Polyester fiber flexible composite strap extruder production line is an advanced equipment specially designed for producing high-strength and durable polyester fiber composite straps. The production line mixes polyester fiber with other materials and forms a composite strap with high tensile strength and excellent wear resistance through an extrusion process. The equipment includes core parts such as automatic feeding system, extruder, cooling system, traction device and automatic winding system.

Characteristics of Composite strap production line include:

Raw Material Handling and Preparation

  • Raw Materials: The primary materials include polyester or polypropylene resin, fiberglass, or other reinforcing fibers.

  • Material Storage: Silo or storage tanks for raw materials to ensure a continuous supply.

  • Feeding System: Precise feeders for accurate dosing of raw materials.

Extrusion Process

  • Extruder: A twin-screw extruder is typically used to melt and mix the raw materials uniformly.

  • Die Head: The die head shapes the molten material into the desired strap profile.

  • Calibrating Unit: Ensures the strap maintains its shape as it cools.

Reinforcement Integration

  • Fiberglass or Reinforcement Integration: Incorporation of reinforcing fibers into the molten plastic to enhance strength. This could involve a roving frame that feeds continuous fibers into the extruder.

  • Tension Control System: Maintains the correct tension of the reinforcing fibers as they are integrated into the strap.

Cooling and Solidifying

  • Cooling Tank or Bath: The extruded strap passes through a water bath or air cooling system to solidify.

  • Cooling Rollers: Additional rollers to aid in the cooling process and maintain the strap's shape.

Stretching and Orientation

  • Orientation Unit: This unit stretches the strap to align the molecular structure and enhance tensile strength.

  • Heating and Stretching: Often involves heating the strap slightly before stretching to achieve better orientation.

Surface Treatment

  • Printing and Marking: Optionally, the strap can be printed with logos, specifications, or other markings.

  • Embossing: Surface embossing for additional grip and aesthetic appeal.

Cutting and Winding

  • Cutting System: Automated cutters that cut the strap to the desired length.

  • Winding Machine: Collects the strap onto rolls or spools for easy handling and packaging.

Quality Control

  • Inspection Systems: Online inspection systems check for defects in the strap, such as thickness variations, surface defects, and strength consistency.

  • Testing Equipment: Off-line testing for tensile strength, elongation, and other mechanical properties.

Automation and Control Systems

  • PLC Systems: Programmable logic controllers for precise control of the production process.

  • HMI (Human-Machine Interface): User-friendly interfaces for monitoring and controlling production parameters.

  • Data Logging: Systems to log production data for quality control and traceability.

Environmental Control

  • Dust and Fume Extraction: Systems to manage any dust or fumes generated during production.

  • Recycling Systems: Reprocessing of scrap or off-spec material back into the production line.

Maintenance and Safety Features

  • Safety Guards and Interlocks: Ensuring operator safety around machinery.

  • Maintenance Access: Design considerations for easy access to components for maintenance and cleaning.
