High-precision weighing filling machine

Abstract

The invention relates to a filling machine, in particular to equipment which combines an automatic weighing feedback technology and a PLC (Programmable Logic Controller) control system and controls the flow according to a flowmeter for high-precision filling. Technically improved on the traditional filling equipment, the filing machine comprises the PLC control system, a weighing device, a weighing feedback system, a touch screen, a flowmeter and filling equipment. The filling equipment is characterized in that all the flowmeter, the PLC control system, the touch screen, the weighing device and the weighing feedback system are arranged on the filling equipment, wherein the PLC control system is connected with the touch screen; a signal is transmitted by the touch screen through the PLC control system; the weighing device is connected with the weighing feedback system; a signal is transmitted by the weighing device through the weighing feedback system; and finally the signals are concentrated on the filling equipment for controlling the filling quantity. The filling machine is a device which has the advantages of convenient operation, accurate filling, high degree of automatic control and capability of automatically adjusting the specific weight of materials in any degree for filling.

Description

Technical field: [0001] The invention relates to a filling machine, in particular to a device which combines automatic weighing feedback technology with a PLC control system and controls the flow rate through a flow meter for high-precision filling. Background technique: [0002] The filling machine is a well-known widely used production device, but the filling technology of the known filling machine is to control the filling time by controlling the filling volume, that is, by using the PLC control system to control the opening and closing of the solenoid valve time to control the filling volume. However, there are many troubles in the adjustment of filling technology at present. For example, after filling, it needs to be calibrated and weighed every time, and the parameters are manually set according to the filling volume of each time, especially after changing materials. The specific gravity of the material is different, and each filling head needs to be changed. Firstly,...

However, there are many troubles in the adjustment of filling technology at present. For example, after filling, it needs to be calibrated and weighed every time, and the parameters are manually set according to the filling volume of each time, especially after changing materials. The specific gravity of the material is different, and each filling head needs to be changed. The first is that the filling accuracy is not high, and the second is that manual operation takes a long time to adjust. In the process of automatic control, various problems will occur.
