Weighing device for in-line filler

Abstract

The invention relates to a weighing device for in-line filler, which comprises a control cabinet, a PLC system, a weighing device, a weighing feedback system, a high-accuracy operational amplifier, a solenoid valve, a touch screen, data wires and a control screen for control cabinet. In the invention, the high-accuracy operational amplifier is integrated with the weighing device and the control cabinet, the computation results of the high-accuracy operational amplifier are displayed on the control cabinet via a screen, the weighing device is arranged on one side of the control cabinet in a fixed connection manner and the high-accuracy operational amplifier and the weighing feedback system are connected with the PLC system of the filler by data wires. During the filling by the filler, the filler controls the flow rate via the solenoid valve and the PLC system performs the adjustment through the touch screen or control screen for control cabinet. The weighing device for in-line filler is a high filling accuracy device which is convenient to operate, has high degree of automated control and can fill the materials with automatic adjustment regardless that how the proportion of the materials changes.

Description

Technical field: [0001] The invention relates to a filling machine, in particular to a weighing device capable of automatic in-line filling machine. 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, the filling accuracy is not high, and secondly, manual operation takes a long time to adjust. In the...

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.
