Routine Maintenance Details for Quantitative Feeders

Quantitative feeders are devices that integrate weighing and feeding control, often used to control the infeed volume in production lines. The accuracy of feeding directly affects the precision of ingredient proportions, and the stability of feeding directly impacts production continuity. In other words, the precision and stability of feeders directly influence the quality and quantity of production. To ensure the stability and accuracy of quantitative feeders, apart from their inherent performance, the usage and maintenance specifications during actual operation are equally important. Correct usage and maintenance can ensure long-term stability of the equipment during operation.

1.Maintenance Precautions for the Mechanical Parts of Quantitative Feeders

·Ensure good lubrication of rollers and idlers.

·Maintain the running track of the belt to prevent belt deviation.

·Keep the belt clean and promptly remove any spilled material.

·Ensure the tensioning device operates normally.

·Prevent belt scratches and cracks.

Maintaining belt cleanliness, while seemingly simple, is crucial as it ensures that the feeder only weighs the intended material, not any adhered to the belt. Additionally, leaked material accumulating or becoming lodged between the belt, idlers, or sensors can severely affect measurement accuracy. To maintain belt cleanliness, an automatic belt cleaning device can be installed.

2.Maintenance Precautions for the Electrical Parts of Quantitative Feeders

·When welding is necessary for routine maintenance on the scale body, ensure that the welding current does not pass through the feeder's weighing or speed sensors to avoid damage.

·When replacing the belt, be cautious to lift the sensor's protective bracket to prevent overload damage to the sensor.

·Long-term belt operation can cause tension changes; regular calibration and tare operations should be performed.

3.Precautions Before Calibration

·Check if the scale body is clean, if there is material stuck to the belt, if the belt tension is constant and appropriate, if the belt is running straight, if there is any material lodged between the belt, idlers, and weighing sensors, and if the rollers and each idler are flexible and operating normally. The electrical parts should focus on checking if the sensors are functioning properly.

·If any issues are found, they must be resolved promptly; calibration should not be performed with existing issues.

4.Routine Maintenance Content for Quantitative Feeders

·For the scale frame, perform daily cleaning, check for any lodged material, inspect if the fastening bolts are loose, and ensure idlers rotate freely.

·The belt, rollers, and idlers are prone to material accumulation. Adjust the spacing between the outer cleaner's rubber plate and the belt based on the actual situation to eliminate the impact of accumulated material on measurement accuracy.

·Avoid arbitrarily moving or stepping on the scale body supports to prevent damage to the weighing sensors due to overload.

·Ensure that the conveying and weighing idlers rotate freely without any stagnation. The weighing idlers should not frictionally contact the scale body or belt, as this not only affects weighing accuracy but may also damage the motor or reducer.

·If electric welding is required on the scale body, the quantitative feeder controller must be powered off. Maintenance personnel should connect the grounding wire close to the welding area; otherwise, current passing through the weighing sensors could cause damage.

·If changing materials or adjusting the feeding rate range is necessary, consider the specific circumstances and, ideally, consult with the original manufacturer for confirmation. The selection and design of quantitative feeders are based on user needs, including capacity and material characteristics. If changes are necessary, consider feasibility first and avoid unnecessary replacements. When material changes become unavoidable and existing components cannot meet the requirements, consider replacing the components accordingly.
