How to Prevent Bottle Jams at the Star Wheel

Overview

This guide covers the practical steps to prevent bottle jams at the star wheel. JSLT Engineering Plastics produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Verify pocket-bottle clearance. 0.5–1.5mm clearance; measure with feeler gauge.
2. Synchronize timing screw and star wheel. Bottle pitch on screw must match star wheel pitch.
3. Check guide rail alignment. Bottle leans cause pocket entry jams.
4. Inspect star wheel for wear. Worn pockets > 2mm clearance cause bottles to wobble.
5. Replace at 50% wear. Plan replacement before pocket wear causes line stops.
