Learn how to adjust triangle blades on a string bean head & tail cutting machine. Proper blade alignment ensures precise cutting, prevents friction, and extends blade life. A practical guide for operators and maintenance teams.

Triangle Blade Adjustment for String Bean Head & Tail Cutting Machine

Proper maintenance of your string bean (yardlong bean) head and tail cutting machine is essential to ensure efficient operation and long-lasting performance. One of the most important maintenance tasks is the adjustment of the triangle blades. If the blades are not correctly aligned with the drum, it can lead to poor cutting quality, increased wear, and even potential damage to the machine.

In this guide, we show step-by-step how to adjust each triangle blade. Each blade should be set to sit closely against the drum—tight enough to cut the bean heads and tails efficiently, but not overly tight to avoid friction that could wear down the blade or the drum. Adjusting the blade handle individually ensures precise alignment and consistent cutting performance.

Proper triangle blade adjustment has several benefits:

1. **Efficient Cutting** – Correctly aligned blades remove bean heads and tails cleanly and consistently.
2. **Reduced Wear** – Avoiding excessive friction prevents premature blade and drum damage.
3. **Smooth Operation** – Well-adjusted blades ensure the machine runs quietly and smoothly, reducing downtime.
4. **Extended Blade Life** – Regular maintenance and proper adjustment prolong the service life of your blades.

The accompanying video demonstrates the full adjustment process, showing how to check the blade alignment, adjust the tension on each blade, and verify that all blades operate smoothly against the drum. This visual guide is especially useful for machine operators and maintenance staff, helping them quickly master the adjustment process and maintain optimal performance.

Regular maintenance and proper blade adjustment not only improve cutting quality but also enhance overall productivity. We recommend performing this check routinely to keep your string bean cutting machine in peak condition.
