Description

TECHNICAL FIELD

[0001] The utility model relates to the field of batching, in particular to a powder continuous batching device. BACKGROUND

[0002] In the prior art, dynamic weighing is usually used for continuous batching of powder. However, the dynamic weighing has low calibration accuracy and high calibration difficulty. In addition, during the continuous batching process, manual material receiving is required, and the received material is weighed and compared with the dynamic weighing data to calibrate the dynamic weighing. Furthermore, the dynamic weighing has large measurement deviation during the start and stop stages, and the small amount of manually received material cannot offset the measurement deviation during the start and stop stages, resulting in large measurement deviation of the dynamic weighing during calibration, which leads to low batching accuracy and low product quality during production. To solve the problem of low accuracy of dynamic continuous batching, the prior art usually adds a transition bin at the front end of the dynamic weighing, and a weighing device is added to the transition bin. This method can improve the calibration accuracy during dynamic calibration, but the calibration amount is still small, which cannot offset the measurement deviation of the dynamic weighing during the start and stop stages. With the increase of production capacity, the calibration accuracy will still cause large weight deviation. In actual production, the weighing value of the transition bin is still dynamically fluctuating. Although the static weighing principle is used, the material is still in a dynamic flow state during the weighing process. The batching accuracy of the dynamic weighing is controlled by the descending rate of the weighing value. The essence is still dynamic weighing. Although the calibration accuracy is improved, it is still difficult to offset the measurement deviation of the dynamic weighing during the start and stop stages and still causes large batching weight deviation.
