Description

Technical Field

[0001] The utility model belongs to the technical field of fully sealed quantitative feeders, in particular to an automatic cleaning fully sealed quantitative feeder. Background Art

[0002] The fully sealed quantitative feeder operates on the same principle as a belt scale. As material passes through the belt, weight and speed signals are transmitted to a secondary instrument. The instrument uses amplification, A / D conversion, and calculations to determine flow rate and accumulated weight. Based on the user-set quantitative value (PID parameters), the instrument performs self-tuning and outputs a control current proportional to the flow rate to a variable frequency controller. The variable frequency controller changes the motor speed, thereby varying the feed rate to achieve quantitative feeding.

[0003] Traditional fully sealed quantitative feeders, due to the stickiness of some materials, can cling to the conveyor belt during feeding. This long-term accumulation can affect production efficiency and product quality. Furthermore, as materials enter the belt inside the fully sealed quantitative feeder, they can accumulate. This accumulation can lead to uneven material distribution, affecting the accuracy of the metering sensor. To address this, we propose an automatic cleaning fully sealed quantitative feeder.
