Quantitative filling machine

Abstract

The invention relates to a filling device, and especially relates to a quantitative filling machine for separate filling of liquid beverages and medicines; the filling machine comprises a filling tube, a liquid storage tank, a filling head, and a delivery mechanism; the filling tube is provided with electric-control filling valves, and flowmeters; a control system connected with each of the electric-control filling valves and flowmeters is disposed; the filling head is connected with the liquid storage tank through the filling tube. Present mechanical filling valves are substituted by the electric control filling valves; the filling amount is controlled by the control system according to monitoring signals of the flowmeters; and thus the quantification has high precision; When one filling is completed, no liquid supplement is required for a measuring cup, and thus the filling speed is high; no ejector pin mechanism, measuring cup and liquid-supplement mechanism thereof, or tray elevating mechanism is required to be disposed, and thus the structure is simple with less parts, and the machine is convenient for use and maintenance; the electric-control filling valves and flowmeters can be replaced directly; the machine is convenient for dismounting, and only has requirements for the corresponding relation of a container bottle and the filling head; therefore the maintenance, adjustment and calibration are simple, and the equipment utilization rate is high.

Description

technical field [0001] The invention relates to filling equipment, in particular to a quantitative filling machine for subpackaging liquid beverages and medicines. Background technique [0002] In the sub-packaging of liquid beverages and medicines, quantitative filling machines are required for filling. The existing quantitative filling machine is a mechanical structure, including a frame, a liquid storage tank, a liquid level control device for the liquid storage tank, a filling pipe, a filling head, a conveying device for a container bottle, and a tray installed on the conveying device. , Tray lifting mechanism, measuring cup, filling valve, ejector mechanism, etc. When working, the container bottle is placed on the tray, stepping along with the conveying device and corresponding to the filling head at each filling position, and then the container bottle rises with the tray under the action of the tray lifting mechanism and acts on the ejector mechanism through the bottl...

AI Technical Summary

Problems solved by technology

Therefore, the existing quantitative filling machines have the following problems: 1. Affected by the accuracy of the measuring cup, the flow state and foaming during liquid replenishment, the quantitative accuracy is low; 2. After a filling is completed, the measuring cup needs to be replenished with liquid , so the filling speed is slow; 3. Due to the lack of lubrication means, the ejector mechanism, filling valve, and liquid replenishment mechanism wear a lot, and maintenance needs to be carried out after filling a certain amount to avoid problems such as lax closing and jamming of the ejector rod. High maintenance cost and low utilization rate of equipment; 4. In order to avoid the influence of wear and corrosion on product quality, the service life of parts is short; The corresponding relationship between the height difference of the container bottle, the ejector mechanism and the container bottle is strictly required, so the maintenance and adjustment are cumbersome
