Continuous Winding Machine for Long FRP Products
Continuous winding machine that impregnates, winds and cures fiber in one pass, producing long FRP pipes and profiles with even wall thickness at steady output....
Product Overview
The continuous winding machine is continuous forming equipment for long composite products. Once the fiber is impregnated with resin, it is laid down, wound and cured continuously on a driven mandrel or forming die, and the product comes off the line without interruption. The machine runs in an unbroken sequence with a steady forming rhythm, and suits batch production of pipes, profiles and other products that can be formed continuously.
Structure and Components
The machine is made up mainly of the frame and bed, the drive and haul-off mechanism, the winding spindle or rotary forming die, the guide eye and resin bath, tension control, the curing tunnel and the electrical cabinet. The bed provides overall support and the guide rail datum; the haul-off mechanism carries the product forward continuously; the winding unit lays down the fiber; the curing tunnel completes resin curing; and the control system coordinates the speed and parameters of each section.
Working Principle
Reinforcing fiber is impregnated with resin in the bath and then led by the guide eye onto the surface of the continuously moving forming die or mandrel, where fiber layers are laid down one by one as the product advances and the winding motion works in step. On reaching the designed number of layers, the product enters the curing zone to set, then passes through haul-off and cutting to give cut-to-length products. Controlling winding angle, layer count, haul-off speed and curing conditions keeps wall thickness even and structural performance stable.
Performance Features
The machine forms products continuously without interruption, so output is higher than with batch winding. Haul-off and winding speeds are interlocked and coordinated, so specifications stay consistent along the product length. Fiber placement and angle are adjustable to suit products of different section and wall thickness. Electrical parameters can be set and stored by product type, which simplifies changeover and batch production management.
Suitable Products
The machine suits FRP pipes, profiles and other long composite products that can be formed continuously, and can serve part processing in water supply and drainage, chemical anti-corrosion, power protection and environmental protection fields. Product section size, length and wall thickness are determined together with die specifications and output requirements.
Selection and Maintenance
When selecting a machine, combine product section size, length, wall thickness, fiber type and daily output to define forming die specifications, haul-off stroke and curing tunnel configuration. In daily use, keep the guide rails, drive and haul-off parts clean and lubricated, check tension, guide eye, resin bath and curing system status regularly, and replace wear parts as specified to keep the machine running reliably.
FAQ and Operating Tips
Before start-up, check that the product process parameters match the die and speed settings, then run the machine without load to confirm that all sections act in step. During production, watch the resin pick-up, lay-up evenness and curing result, and stop for inspection promptly if lay-up deviation or haul-off faults appear. After shutdown, clean residual resin from the resin bath and guide eye, lubricate the drive parts and keep running records.
