Problems solved by technology

[0007] Aiming at the problem that the existing filling device cannot accurately control the liquid level, the present invention provides a non-contact liquid filling device. When filling liquid materials into the container, when the liquid level in the filled container rises to the measurement After the catheter extends into the end nozzle, the internal pressure changes and the pressure detector is triggered to control the filling action of the filling unit, so as to ensure that the liquid levels of the filled liquid materials in all containers are consistent. Achieved the effect of precisely controlling the height of the filling liquid level

Embodiment 1

[0060] like figure 1 As shown, the non-contact liquid filling device of this embodiment includes,

[0061] Filling unit 1, which is used to fill liquid materials into containers;

[0062] The detection and control unit 2 is used to detect the height of the liquid material in the container to be filled, and to control the start and stop of the filling unit 1;

[0063] The detection and control unit 2 includes a measuring catheter 20 and a pressure sensor 21;

[0064] One end of the measuring conduit 20 extends into the container to be filled, and the other end is connected to the pressure sensor 21;

[0065] The pressure sensor 21 detects the pressure change in the measuring conduit 20 and is connected with the filling unit 1 to control the start and stop of the filling unit 1 .

[0066] In the prior art, the filling device cannot effectively control the liquid level in the same production line to be consistent. The reason is that in addition to the defects of the filling va...

Embodiment 2

[0072] like figure 1 As shown, the non-contact liquid filling device of this embodiment is further improved on the basis of Embodiment 1, and further includes a three-way valve 3, and two of the flow channel ports of the three-way valve 3 are connected to the measuring conduit 20 Among them, another flow channel port communicates with the liquid suction pipe 30;

[0073] The liquid suction pipe 30 is used to extract liquid materials.

[0074] The three-way valve 3 of this embodiment is arranged on the measuring conduit 20 outside the container, and the three-way valve 3 is divided into three paths, two of which are connected to the measuring conduit 20, and one of which is connected to the suction pipe 30. When filling liquid materials, the three-way The valve 3 connects the two paths connected to the measuring conduit 20 so that the pressure sensor 21 can effectively detect the pressure change in the measuring conduit 20. After the filling stops, the three-way valve 3 is swi...

Embodiment 3

[0077] The non-contact liquid filling device of this embodiment is further improved on the basis of Embodiments 1 and 2, and the height of the end face of the measuring conduit 20 protruding into the container to be filled is consistent with the set height of the filling liquid level .

[0078] With this setting, after the liquid is pumped through the liquid suction pipe 30, the final liquid level in the container stays at the height of the measuring conduit 20 protruding into the end surface, that is, the set height of the filling liquid level, thus ensuring that each filling The liquid level heights are consistent.

Abstract

The invention discloses a non-contact liquid filling device, which belongs to the technical field of filling. It includes a filling unit, which is used to fill liquid materials into the container; a detection and control unit, which is used to detect the height of the liquid material in the filled container, and control the start and stop of the filling unit; the detection and control unit includes measuring conduits and pressure sensors ; One end of the measuring conduit extends into the container to be filled, and the other end is connected to the pressure sensor; the pressure sensor detects the pressure change in the measuring conduit, and is connected with the filling unit signal to control the start and stop of the filling unit. When the present invention fills the liquid material into the container, when the liquid level in the filled container rises to the point where the measuring catheter extends into the mouth of the end, the pressure in the measuring catheter will change, triggering the pressure detector, so as to control the filling. The filling action of the filling unit, so as to ensure that the liquid level of the filled liquid material in all containers is consistent, and achieve the effect of accurately controlling the filling liquid level.

Description

technical field [0001] The invention belongs to the technical field of liquid filling, and more specifically relates to a non-contact liquid filling device. Background technique [0002] In the hydration production line of the beverage industry, when it comes to the packaging of liquids, most of them use filling valves for filling. The accuracy requirements of the filled liquid level height are getting higher and higher, and many users have put forward requirements for the consistency of the liquid level height after liquid filling, which is a challenge for traditional filling valves. [0003] In the existing liquid filling procedures, most manufacturers use mechanical filling valves for liquid filling. This filling device is popular because of its low cost and convenient processing. However, the filling accuracy of mechanical filling valves Poor, the filling volume is difficult to control, and the valve closing time is long, which may easily cause large deviations in filli...
