What does "Quick Weighing Value" mean

The fast weighing value (fast feeding value) in weighing usually refers to the feeding parameter set in the process of quantitative packaging or weighing to quickly approach the target weight, representing the amount of feeding that should be stopped in advance when using a faster feeding speed (fast feeding). Simply put, it is the target weight value of the machine during the rapid feeding stage. The following is the specific explanation:

1. Simple explanation

Function: Control the node at which the machine stops during the "rapid feeding" stage (when the speed is the fastest) to prevent over-feeding.

For example:

For example, packaging 50 kilograms of rice:

Set the quick weighing value to 45kg → The machine will fill at the maximum speed. Once it reaches 45kg, it will automatically switch to slow feeding.

If it is set at 48kg, it may be overloaded due to inertia. If it is set too low (such as 40kg), it will affect the packaging speed.

2. Why is quick weighing necessary?

Ensure speed: Fill with the maximum flow rate during the rapid stage to save time.

Ensure accuracy: Switch to a slow speed when approaching the target to avoid overcharging (for example, if the grain hits the scale platform, it will cause weight fluctuations).

3. How to set it up reasonably?

General rule: Quick weighing value ≈ 80% to 90% of the total weight

50kg packaging → Quick weighing value set at 40 to 45kg

25kg packaging → Quick weighing value set at 20 to 22kg

Adjust according to the materials:

Good fluidity (such as rice and wheat) : It can be set higher (85% to 90%) because it is less likely to get stuck.

Dust-prone/fragile (such as flour, feed) : Set it lower (80% - 85%) to reduce impact and dust.

4. Common Questions

Question 1: The quick weighing value is set too high (such as 48kg)

Result: Inertia caused it to reach 50.5kg, which is overweight!

Solution: Lower the fast weighing value (such as 45kg) to leave room for the slow speed stage.

Question 2: The quick weighing value is set too low (such as 30kg)

Result: The packaging speed is slow and the efficiency is low.

Solution: Appropriately increase the quick weighing value, but the inertial error needs to be tested.

In a nutshell: "Quick weighing is the braking point for a machine to 'charge ahead'. Setting it too early wastes time, while setting it too late can easily lead to overloading!" When debugging, first set it at 85% of the total weight, and then make fine adjustments according to the actual situation.
