Direct Extruder Parallel Winding Pet Strap Semi-auto Winder

Direct Extruder Parallel Winding Pet Strap Semi-auto Winder
Overview

The CQ800 semi-automatic PET strap winder supports direct parallel winding from the extruder. After cooling, the strap enters the winding station directly from the extruder exit, eliminating the need for accumulator stands or buffer equipment. This direct integration effectively shortens the total production line length, reduces strap exposure time, and lowers contamination and stretching risks. The machine uses a dancer constant tension system to automatically compensate for minor speed fluctuations between extrusion and winding, ensuring smooth operation. Available with 1 or 2 mandrels, the CQ800 can be directly linked to the extruder line for efficient extrusion-to-winding integrated production, ideal for new plants or those wanting to optimize line layout.

Key Features
  • Direct connection - Eliminates accumulator and buffer rollers, simplifies line.
  • Speed adaptive - Dancer constant tension automatically compensates extrusion/winding speed differences.
  • Shortens line length - Reduces equipment footprint, lowers building cost.
  • Reduces contamination - Short exposed strap path lowers dust and oil pick-up.
  • Prevents stretching - Fewer rollers reduce accidental strap deformation.
  • Easy installation - Place after extruder cooling section; no line modification needed.
  • Automation ready - Can communicate with extruder PLC for coordinated control.
Frequently Asked Questions
Q1: Does direct extruder integration require retrofitting my existing line?
No. Simply place the CQ800 1-2 meters after the extruder cooling bath or air-cooling section, then re-thread. Your existing accumulator can be kept or removed.
Q2: How does the winder handle extruder speed fluctuations?
The dancer constant tension system continuously senses strap sag or tension and automatically adjusts winding motor torque and speed to absorb differences, ensuring smooth winding.
Q3: When winding two straps (dual-mandrel model), can each side have its own speed control?
Both straps share the same extruder speed, but each winding station has an independent dancer tension control, allowing individual tension adjustments for minor side-to-side differences.
Q4: If the extruder stops temporarily, will the winder stop automatically?
Yes. By connecting signals, the extruder stop signal can be sent to the winder PLC, which will slow down and stop to avoid strap accumulation or tearing.
Q5: Does direct integration improve strap quality?
Yes. The shortened path from extrusion to winding reduces friction and bending over intermediate rollers, resulting in better surface finish and improved dimensional stability.
