What are the factors that affect the stable operation of the checkweigher?

What factors are easily affected by the checkweigher during operation:

1. The packaging of the measured items, including bags, cans, and bottles. The weight tolerance between the same packaging, whether the bottom of the cans and bottles is flat, the bottom diameter, and the height will affect the vibration generated when the measured items enter the scale.

2. The material of the measured items, transparent items and reflective items, will affect the induction of the photoelectric switch; but we can effectively avoid this problem by using the non-photoelectric weight recognition mode to check the weight.

3. The speed of the measured items, the faster the belt speed, the shorter the system reading time, the greater the impact on the accuracy; the number of items detected per minute will also affect the accuracy.

4. The shape of the measured items, the bottom of the special-shaped items is uneven, and the vibration is large when entering the scale, which also has a great impact on the accuracy.

5. The weight of the measured items, the heavier the items, the lower the accuracy.

6. The characteristics of the measured items, including liquid, solid, and powder. When liquid items enter the weighing platform, the conveyor belt of the weighing platform is moving, and the shaking of the liquid inside will cause the center of gravity of the items to change; when solid items enter the weighing platform, the vibration generated by the object is large and lasts for a long time, and the system must enable secondary filtering to resist vibration; when powdered items enter the weighing platform, the powder in the package may also flow, which will also cause the center of gravity of the item to change.
