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] The following is a further detailed description based on the accompanying drawings: taking the method and device for controlling the filling port liquid level of a fresh milk (or other liquid food such as beverage) filling machine as an example for description. The cylindrical packaging material 9 moves downwards 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, and at the same time, it is pressed into a rectangular shape, so that the sealing part 15 is sealed by 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 and the square are sealed by the packaging material. The cylindrical packaging mater...

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 field [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 the filling port of a liquid filling machine. 2. Background technology [0003] There are currently two methods and devices for level control of the filling port: one is that the delivery pump continuously delivers the filling liquid to the container through the pipeline and the liquid flow control valve. When the liquid level detection sensor detects the filling liquid in the container When the liquid level is higher than the set height, the liquid level controller reduces the opening of the liquid flow control valve, so that the flow of the perfusion liquid 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 filling liquid in the container is lower than the set height, ...
