The effectiveness of the stretch film dispenser directly impacts the quality of the final packaged product. A well-designed dispenser ensures consistent tension, minimal film waste, and secure wrapping.

4. Vertical Movement System

To ensure complete coverage of the PVC pipe coil, the machine incorporates a vertical movement system for the film dispenser. This system typically includes:

• Vertical guide rails: Provide a stable track for the dispenser’s up and down movement.
• Motor-driven mechanism: Powers the vertical motion, often using a ball screw or chain drive system.
• Position sensors: Monitor and control the dispenser’s height relative to the coil.

The precision of the vertical movement system is crucial for achieving uniform coverage from top to bottom of the coil, regardless of its height.

5. Control Panel and Interface

The control panel serves as the brain of the PVC pipe coil packing machine. Modern machines often feature:

• Touchscreen interface: Allows for easy input of packing parameters and machine control.
• Programmable logic controller (PLC): Manages the coordination of all machine components.
• Recipe storage: Enables quick setup for different coil sizes and wrapping patterns.
