Employees conducted free verification of each weighing device, such as electronic price scales, platform scales, and counter scales, used in trade settlements at the various stalls and shops in the agricultural and sideline products market, and made detailed records. Verification certificates were prominently posted on the measuring equipment, and any non-compliant devices were immediately ordered to be stopped by the operators on the spot. The establishment of "Fair Scales" aims to protect the legitimate rights and interests of consumers, highlight the effectiveness and social impact of measurement work, while the re-weighting rate directly reflects consumers' trust in businesses. Cheating customers will face severe penalties.
II. Characteristics of the Weight Loss Scale Blending System:
1. Extremely high metrological control accuracy
2. Suitable for continuous or batch feeding requirements
3. Suitable for powders, granules, and other loose materials
4. The entire system is sealed, therefore it will not contaminate the environment.
5. Manual or automatic mechanical filling options available
6. During filling, the rate of filling must be sufficiently fast.
7. Explosion-proof types
8. Can connect multiple devices to the supervisory control system to form a distributed batching control system.
III. Improved Control Method for Weight Loss Scale Blending System
When the measurement of a scale reaches the feeding set value, stop feeding. After all scales have stopped feeding, the entire feeding process is complete, with a duration of T1. To enhance measurement accuracy, reduce this impact over a subsequent period, but since maintaining ingredient accuracy is crucial, T2 and T4 cannot be too small, and static measurement of the scales is performed. After measurement is complete, the Weifang flowmeter, with computer control, simultaneously releases all discharge electro-magnetic vibrators. The discharge process is similar to the feeding process, with the computer still performing dynamic monitoring. The flowmeter manufacturer, the discharge time is T3. To minimize errors, after discharge, a period T is allowed for the flowmeter consultation, followed by static measurement. With this, one batching cycle is completed, and the next batching cycle can begin. The cycle is defined as: T = T1 + T2 + T3 + T4.
Is there any dirt on or around the scale body, and are there any lumps inside the scale body?
Check for any blockages in the feeding and discharging mechanisms of the weigh hopper, as well as for any material leakage in the feeding and discharging valves.
The body's upper and lower soft connections for caking and blockage, flow meter pricing, and whether the connection structure is affected by external forces. Whether the dust removal device on the body is blocked or obstructed.
If the weighing body has limit positions, check if the limit gap is reasonable, and the limit bolt should not touch the weighing body.
Check the pressure of the air source and ensure the normal operation of the pneumatic three components.
Weight sensors and speed sensors
Sensor mounting point for any dirt or rust.
Are there any loose or deformed screws for sensors or accessories?
Sensor ground wire and return cable for looseness and rusting.
Sensor cable for any insulation damage, crushing, or kinking conditions.
Waterproof connectors for cable in and out of the junction box, check for loose cable connections, and ensure the junction box is not damp, especially when used outdoors.
Electrical Control Cabinet (Box)
Check the accuracy of the scale (calibrate the scale), especially for scales with multiple sensors (more than 3 sensors).
Check the wiring terminals of the gauge for looseness, dirt, lumps, or moisture.
Check if the instrumentation power supply is functioning properly.
Inspect the cables from the junction box to the meter for any signs of insulation damage, crushing, or kinking.
Check for insulation damage, crushing, or kinking in the communication cables from the instrument to the computer or PLC.
Check the grounding wire and grounding point of the instrument for good contact.
Regularly dust the control cabinets (boxes), especially in places with high dust levels.
