Turntable-type quantitative feeder

Abstract

The invention relates to a turntable-type quantitative feeder, comprising a charging hopper which is internally provided with a spiral feeding passage with an inlet end and an outlet end; the outlet end is provided with a distributor which is internally provided with a space for containing articles; the internal bottom surface of the distributor is a slope surface which inclines downwards gradually from the center to the external edge; the internal space of the distributor is divided into a plurality of distribution bins by a plurality of screens that are arranged along the radial direction; the dimension parameter of each distribution bin is matched with the total volume of the material in the distribution bins; the distribution bins can rotate around a central line; each distribution binsequentially passes by the outlet end of the feeding passage during the rotation process and takes away the fallen materials; the lower end of the charging hopper is also provided with a material outlet; during the rotation process of the distribution bins, each charging bin is sequentially communicated with the material outlet; and the materials in the bins slide out by the material outlet. By controlling the rotation speed of the distribution bin, the amount of the materials at the material outlet can be controlled exactly, thus realizing the feeding quantization.

Description

technical field [0001] The invention relates to a turntable type quantitative feeder for material feeding control. Background technique [0002] At present, the feeding of rolling body materials mainly depends on firstly vibrating the feeding, and then controlling the feeding amount of the materials by weighing. Specifically: first, slide the rolling element material from the loading hopper to the vibrating feeder, and vibrate the hopper to slide the material to the discharge hopper. When the weighing sensor on the discharge hopper reaches the limit value, stop the vibration, and the discharge hopper is sent to the furnace. . [0003] The above-mentioned method of firstly discharging the material through vibration and then relying on the load cell to weigh the output amount, although the feeding amount of the material can be known intuitively. However, it takes a long time to wait for the discharge hopper on the load cell to completely stop vibrating, so when using the loa...

AI Technical Summary

Problems solved by technology

This situation of reading data when shaking will inevitably cause errors in weighing, and because the general loading is weighed in batches, the error of each batch of weighing will add up to become larger, therefore, The weight error of the feed material weighed by the above-mentioned weighing sensor is very large

In addition, the sensor is easily damaged and malfunctions, which affects the weighing
