High-precision multi-stage vibration feeding device and method

Abstract

The invention provides a high-precision multi-stage vibration feeding device and method. The high-precision multi-stage vibration feeding device comprises a fixing plate, a plurality of vibration assemblies and a plurality of feeding grooves installed above the vibration assemblies, and the feeding grooves comprise the first-stage feeding groove used for bearing and conveying materials and the fine-adjustment feeding groove which is close to one end of a weighing hopper and used for adjusting and controlling precise discharging; the vibration assemblies are installed on the fixing plate through supporting parts, the supporting heights of the multiple supporting parts are distributed in a stepped mode from high to low, and a multi-stage stepped feeding groove structure is formed. The multi-stage vibration feeding grooves are arranged, the step of discharging and feeding materials and the step of discharging the materials into the weighing hopper for weighing and distributing the materials are separated for stepped feeding, meanwhile, the vibration frequencies and the working time in the different steps are controlled, and when the vibration frequency and the working time are close to a preset value, low-frequency vibration is adopted, and meanwhile work of the feeding grooves is stopped, the weighing error is effectively controlled, and the device is efficient and practical.

Description

technical field [0001] The invention relates to the technical field of ingredient weighing devices, in particular to a high-precision multi-stage vibration feeding device and method. Background technique [0002] In industrial production, especially in pharmaceutical production, it is often encountered in the control of multiple material ratios. In most cases, workers weigh different raw materials according to the required ratio, and then weigh the raw materials Add it to the heat preservation barrel in turn, and through a series of processes such as stirring and mixing, the finished product is finally obtained. In this process, not only many workers are required to cooperate with the operation, the labor intensity is high, and it is easily affected by the proficiency of the workers, and the batching accuracy is not high, which affects the quality of the final product. With the upgrading of my country's manufacturing enterprises, improving the level of automation has increa...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structure of the device for weighing and distributing medicines is relatively simple. Although it can also achieve the function of transporting medicines, it cannot effectively achieve high-precision component control for medicine collection, so that the produced packaging samples often appear total. Quantitative errors, so a new feeding device is urgently needed to solve the problems in the prior art
