Abstract

The invention relates to the technical field of feeding setting, in particular to a rotation rationing feed device and a metering method thereof. The rotation rationing feed device comprises an outer shell, a rotating wheel, a feed port and a discharge port, wherein the rotating wheel is arranged in the outer shell in a rotatable mode, the rotating wheel is provided with a plurality of blades arranged evenly, the feed port and the discharge port are formed in the outer shell, and sector spaces containing materials are formed between every two adjacent blades. The rotation rationing feed device further comprises a weighing device, the connecting lines of the supporting points of the feed device are located on one side of the center of equipment, the weighing device is arranged on the other side of the center of the equipment, and the weighing device is located on the central line of the connecting lines of the supporting points. According to the metering method of the rotation rationing feed device, weighing and calculation are carried out on the materials in each sector space, adjustment on the rotating speed of the rotating wheel is carried out aiming at the materials in each sector space, the metering accuracy of rotation type rationing feed equipment can be improved effectively, and the stability of the instant feeding rate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of feeding arrangement, in particular to a rotary quantitative feeding device and a metering method thereof. Background technique [0002] The metering control method of the rotary quantitative feeding equipment on the market adopts the continuous metering control method: the effective fan-shaped weighing section weighs the weight of the instant material, and the product of the weight and the instant speed is the instant flow rate, and then according to the production needs The design flow rate is adjusted by electrical control to adjust the real-time speed of the rotary wheel of the equipment, so that the real-time flow rate of the delivery is equal to the design flow rate, and the purpose of quantitative delivery is achieved. [0003] Due to the mechanical characteristics of the rotary quantitative feeding equipment: it is impossible to evenly distribute the material in the fan-shaped space between the bla...

Problems solved by technology

[0003] Due to the mechanical characteristics of the rotary quantitative feeding equipment: it is impossible to evenly distribute the material in the fan-shaped space between the blades of the rotary wheel of the rotary quantitative feeding equipment, that is: in each fan-shaped space in the effective fan-shaped weighing section The amount of material is different and the difference will be very large, which will cause a large deviation in the centroid of the material, especially the electrical control system needs to adjust the speed of the rotary wheel of the equipment in real time, which will further increase each The difference in the amount of material in the fan-shaped space and the deviation of the material centroid, while the continuous measurement control method is to calculate the material in the effective fan-shaped weighing section according to the uniform distribution, and the position of the centroid of the material is unchanged, which will be very large. The degree of influence on the quantitative feeding accuracy of the product cannot ensure the stability of the instantaneous feeding rate, which brings great economic losses to the actual production, and even cannot meet the needs of many production processes.
