Multi-station automatic accurate weighing and quantitative feeding system

Abstract

The invention belongs to the technical field of chemical machinery, and particularly discloses a multi-station automatic accurate weighing and quantitative feeding system which comprises a supporting device, a driving device, a feeding device, a feeding device and a control device, and the supporting device comprises a supporting frame and a slewing bearing on the supporting frame; the driving device comprises a power assembly and a rotary indexing table, and the power assembly is used for driving the rotary indexing table to rotate; the rotary indexing table is connected with the inner ring of the slewing bearing; the feeding device comprises a feeder and a circular bracket; the lower end of the circular bracket is fixed on the outer ring of the slewing bearing; the feeding device comprises a plurality of clamping assemblies installed on the rotary indexing table and used for clamping and conveying containers. The control device comprises a proximity switch and a controller, and the proximity switch is installed at the bottom of the rotary indexing table and located below the container. The controller is connected with the proximity switch, the power assembly and the feeder. Automatic butt joint and mixing of the feeding device and the container are achieved, accurate feeding is achieved, and the feeding efficiency and the automation degree are improved.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery, and more specifically relates to a multi-station automatic accurate weighing and quantitative feeding system. Background technique [0002] At present, in industrial processing, powder and liquid are the most used raw materials, and the demand for various powder and liquid feeding equipment is more and more urgent. Powder and some liquids can cause harm to the human body or produce toxic substances, and are not suitable for manual feeding, so automatic equipment is needed instead of feeding. However, there are many feeding equipments now, and there is a common problem in that the degree of automation is not very high, which makes human participation inevitable, and also leads to the above-mentioned problems. [0003] Secondly, because the density and volume of the liquid can be calculated, it is not too difficult to accurately quantify the liquid; for the precise quantitative powder f...

Problems solved by technology

Powder and some liquids will cause harm to the human body or produce toxic substances, so it is not suitable for manual feeding, so automatic equipment is needed instead of feeding

However, there are many feeding equipments now, and there is a common problem that the degree of automation is not very high, which makes human participation inevitable, and will also lead to the above-mentioned problems

[0003]Secondly, because the liquid can calculate the density and volume, it is not too difficult to accurately quantify the liquid; but for the precise quantitative powder feeding system, the most difficult point now is Accurate quantification of powder; due to the uneven distribution of powder, the filling rate and powder viscosity during feeding still have a large error in the quantitative feeding device.
