Problems solved by technology

During the liquid suction process, due to the tension of the liquid, the liquid blocks the recovery exhaust channel with a small diameter, and the exhaust and pressure relief cannot be effectively realized.
[0004] In addition, the existing electronic liquid filling devices are only provided with one filling valve for controlling the filling flow.
When filling liquid, in order to speed up the

Embodiment Construction

[0011] The electronic liquid filling machine in the prior art includes a material cylinder for containing the liquid to be filled into the liquid container, an electronic liquid filling device for filling the liquid in the material cylinder into the liquid container, A container pushing mechanism for pushing the liquid container to / from a position where it can be filled by the electronic liquid filling device and a rotating disk for driving the electronic liquid filling device and the material cylinder to rotate relative to the container pushing mechanism. Since the present invention only relates to the improvement of the electronic liquid filling device, it only focuses on the structure and operation of the electronic liquid filling device, and omits the electronic liquid filling machine which is the same as the prior art and is similar to the present invention. Improve instructions for other parts that are not relevant.

Abstract

The invention provides an electronic liquid filling device which is used for filling a liquid material (20) in a material cylinder (21) into a liquid container (15) and comprises a vacuumizing passage and a pressure-relieving passage. In a working state, one end of the vacuumizing passage is communicated with the liquid container (15), the other end of the vacuumizing passage is connected with a vacuum chamber (18) through a vacuum valve (26), one end of the pressure-relieving passage is communicated with the liquid container (15), and the other end of the pressure-relieving passage is connected with a pressure-relieving chamber (19) through a pressure-relieving valve (17). The pressure-relieving passage and the vacuumizing passage are two mutually independent passages. In a state when the liquid filling is finished, one end of the vacuumizing passage is arranged below the liquid level of the liquid container (15), and one end of the pressure-relieving passage is arranged above the liquid level of the liquid container (15).

Description

technical field [0001] The invention relates to an electronic liquid filling device. Background technique [0002] There are mainly two types of liquid filling devices: mechanical and electronic. Among them, the mechanical liquid filling structure is complex, it is difficult to form a complete isobaric filling, and the liquid level deviation in the container is relatively large after filling. Since the mid-1990s, companies such as KHS and KRONES have successively launched a series of electronic liquid filling devices. These electronic liquid filling devices use probes to control liquid levels, and pneumatic diaphragm valves to control liquids and gases. The switch can realize complete isobaric filling, and the liquid level control is relatively accurate, but the electrical control is complicated, the manufacturing and maintenance costs are high, and the liquid level adjustment workload is heavy when used in different bottle types. [0003] In order to overcome the defects ...
