Why Does the Weighing Belt of the Automatic Weighing Machine on the Assembly Line Go Off-Center?

The primary reasons involve aspects such as installation, material distribution, belt condition, and maintenance. Below are the specific causes and adjustment methods:

Common Causes of Belt Misalignment

Installation Issues

Roller or drum installation not perpendicular: The roller assembly axis is not perpendicular to the belt centerline, causing uneven force distribution; the drum axis is not perpendicular to the frame centerline, or the drum is not level enough. Incorrect tensioner adjustment: The belt tension on both sides is uneven, leading to excessive force on one side.

Material Distribution Impact

Long-term overloading of materials or deviation of the discharge point from the belt center results in uneven tension on both sides of the belt. Adhesive materials accumulate on the drums or belt, forming a conical surface, causing the belt to shift.

3. Belt inherent issues

The aging, wear, or misaligned joints of the automatic weighing machine belt can lead to inconsistent lengths or elasticity on both sides. The belt tension is not suitable (too loose causes side-to-side swaying, while too tight puts excessive local stress).

4. Lack of Maintenance

Material residue on the rollers and drum wasn't cleaned promptly. Belt wear was not regularly inspected, nor were damaged parts replaced.
