Electric feedback quantitative filling valve

Abstract

The invention relates to the field of light industrial machines, in particular to a filling valve applicable to a beer and CO2-contained beverage product linear filling machine. The filling valve is composed of an angle seat valve, a pipeline, a clamping plate, a positive electrode binding post, an insulation rubber sleeve, a filling head, a negative electrode binding post and the like. The angle seat valve and the filling head are connected together through the pipeline. The positive electrode binding post extends into a filling pipe of the filling head to make contact with filling liquid. The negative electrode binding post is installed on the insulation rubber sleeve. The positive electrode binding post and the negative electrode binding post are connected with a PLC. The filling head is sleeved by the insulation rubber sleeve which can move up and down along the filling pipe of the filling head so as to adjust the filling amount. The whole mechanism is connected with a part of a lifting platform of the linear filling machine through the clamping plate. By means of conductivity of the filling liquid, the negative electrode binding column makes contact with liquid inside the filling head, when the liquid level reaches a certain height, the liquid makes contact with the positive electrode binding post, a circuit forms an access, electric signals are transmitted to the PLC, the PLC controls an electromagnetic valve and then controls the angle seat valve to turn off the filling valve, and therefore quantitative filling is completed.

Description

technical field [0001] The patent of the invention relates to the field of light industrial machinery, and is suitable for a filling valve on a linear filling machine for beer and carbonated beverage products. Background technique [0002] With the continuous increase of the output of beer and gas-containing beverages every year, the packaging of large containers of beer and gas-containing beverages is also gradually increasing. As an important part of the beer and gas-containing beverage packaging production line, the linear filling machine has good performance. Bad, directly affects the production progress of the entire production line and the sales market. The traditional linear filling machine controls the filling liquid level by controlling the filling time. Due to the unstable filling pressure, the liquid level control is inaccurate, resulting in unsatisfactory filling. Or a large amount of waste of liquid being poured. Due to the large size of the photoelectric liqui...

AI Technical Summary

Problems solved by technology

The beneficial effect of this scheme is: the problem of inaccurate filling liquid level of the linear filling machine is solved, the insulating rubber sleeve of the filling valve can move up and down along the filling pipe of the filling head, the height can be adjusted, and it can also be replaced by itself The length and size of the wine injection tube can adapt to the requirements of different container heights and different container calibers. The filling valve can be automatically controlled with the PLC device of the filling machine, and it is suitable for all kinds of linear filling machines.
