Problems solved by technology

In the process of controlling the liquid level of the filling port and the device thereof described above, there is a problem of the length of time that the filling liquid flows through the filling liquid processing station between the delivery pump and the filling port. The processing effect of the perfusion liquid treatment station on the perfusion liquid is affected (for example, in the fresh milk filling equipment, the fresh milk sterilization treatment station located between the delivery pump and the filling port, if it flows through the fresh milk sterilization treatment If the time of the station is long, the quality of the fresh milk will deteriorate. If the time of flowing through the fresh milk sterilization treatment station is short, the fresh milk will not meet the sterilization requirements, which will affect the shelf life of fresh milk products); The flow rate changes greatly, and the surface of the filling liquid in the container fluctuates greatly, which makes the surface of the filling liquid in the container unstable, and the level control of the filling liquid in the container is not accurate, etc.

Embodiment Construction

[0016] Further details will be given below with reference to the accompanying drawings: the method and device for controlling the liquid level at the filling port of a fresh milk (or other liquid food such as beverages) filling machine will be described as an example. The cylindrical packaging material 9 moves downward in the direction indicated by the arrow, and the bottom of the cylindrical packaging material 9 is sealed by a sealing device at the sealing part 15 of the packaging material. Together with the cylindrical packaging material 9, a square cylindrical packaging material 14 is formed. During the downward movement of the cylindrical packaging material 9, the upper and lower parts of the square cylindrical packaging material 14 are sealed, and the sealing part 15 of the packaging material and the square The cylindrical packaging materials 14 together form a continuous square cylindrical container 16 . One end of the filling port 10 is fixed on the fixed frame 8, and t...

Abstract

A method and apparatus for controlling the poured liquid level features that a delivering pump controlled by a programmable controller PLC6 is used to pump the liquid from the liquid storage tank through a sterilizing unit to a packing container.

Description

[0001] 1. The fields mentioned [0002] The invention relates to a method and a device for controlling the liquid level of a filling port, in particular to a method and a device for controlling the liquid level of a filling port of a liquid filling machine. 2. Background technology [0003] At present, there are two methods and devices for controlling the liquid level of the filling port: one is that the delivery pump continuously transports the filling liquid into the container through the pipeline and the liquid flow control valve, and when the liquid level detection sensor detects that the filling liquid in the container When the liquid level is higher than the set liquid level height, the liquid level controller reduces the opening of the liquid flow control valve, so that the perfusion liquid flow delivered to the container through the liquid flow control valve is reduced. When the liquid level detection sensor When it is detected that the liquid level of the perfusion li...
