Adjusting Cutting Blades on a String Bean Head and Tail Cutting Machine

Practical Maintenance Tips to Prevent Wear and Improve Cutting Accuracy

Regular adjustment of triangle blades is a key part of maintaining a string bean head and tail cutting machine. When blade positioning is incorrect, cutting performance may drop, and long-term friction can cause unnecessary wear to both the blades and the drum.

Each triangle blade should be positioned close to the drum surface. The goal is firm contact without excessive pressure. If the blade is set too tight, friction will occur during operation, leading to faster wear. If it is too loose, the machine may fail to remove the bean heads and tails cleanly.

Adjustment is done by fine-tuning each blade handle individually. This allows the blade to follow the drum smoothly while maintaining consistent cutting performance. After adjustment, the machine should run smoothly without abnormal noise or resistance.

The accompanying maintenance video provides a clear visual demonstration of this adjustment process. It helps operators and service technicians understand how to check blade alignment, make precise adjustments, and confirm correct operation.

Performing this adjustment regularly helps ensure stable production, reduces downtime, and extends the working life of the cutting components.
