Embodiment 1

[0054] like Figures 1 to 3 As shown, the filling detection mechanism is provided with a rotating shaft 4, and the driving device of the filling machine drives the rotating shaft 4 to reciprocate, and drives the positioning member 3 to swing through the angular range of the reciprocating rotation. The linkage 2 is sleeved on the rotating shaft 4 through the provided rotating hole, so that the linkage 2 can rotate relative to the rotating shaft 4 and is not driven by the rotation of the rotating shaft 4 itself, but only moves under the driving of the positioning member 3 .

[0055] Driven by the rotating shaft 4, the moving route of the driving member 3.1 on the positioning member 3 is arc-shaped. The swinging positioning member 3 pushes the linkage member 2 to swing on the rotating shaft 4 through the driving member 3.1.

[0056] It can be understood that the installation method of the positioning member 3 and the linkage member 2 and the rotating shaft 4 can be one of the fo...

Embodiment 2

[0060] like Figures 4 to 5 As shown, the filling detection mechanism is provided with a track 5 on which the linkage member 2 and the positioning member 3 are slidably installed.

[0061] The positioning member 3 is directly pushed and pulled back and forth by driving the cylinder 6 to make it slide back and forth on the track 5 . Or through the drive wheel 7.1 driven by the drive motor 7, the drive wheel 7.1 pushes and pulls the positioning member 3 reciprocally through the eccentrically installed drive link 7.2, so that it slides back and forth on the track 5.

[0062] It can be understood that the installation method of the positioning member 3 and the linkage member 2 and the track 5 can be one of the following methods:

[0063] like Figure 4 As shown, one is that the positioning member 3 and the linkage member 2 are installed on the same track 5, and the positioning member 3 and the linkage member 2 move in parallel and synchronously slide.

[0064] like Figure 5 A...

Abstract

A filling detection mechanism for detecting a piston pump for filling, comprising a linkage member that is linked with a piston rod provided by the piston pump, and a position measurement capable of reciprocating motion and measuring the relative position with the linkage member pieces. The positioning member is provided with a driving member capable of contacting and pushing the linkage member to move. A reset mechanism capable of resetting the piston rod and the linkage member linked with the piston rod is installed on the piston pump. The filling detection mechanism can detect whether the piston of the plunger pump is in place, so as to automatically detect the stuck and stuck state of the piston, and know that the container filling is unqualified, and directly screen the unqualified products through manual or rejection equipment. Fewer people, high efficiency, can ensure product quality.

Description

technical field [0001] The invention belongs to the field of filling equipment, in particular to a filling detection mechanism. Background technique [0002] The existing automatic filling machine pumps and fills the liquid into the container through the piston pump. When the liquid is injected into the container, the piston is pushed up by the cam; when the liquid is sucked into the piston pump, the piston is pulled down by the return spring. [0003] In order to balance the volume of liquid injected into each container and ensure the filling quality, both the upward and downward movement of the piston need to be in place. When the automatic filling machine is used for a long time, the return spring is easy to age, the elastic force generated is not enough to pull the piston in place, and even the piston is stuck or stuck, making the filling capacity small and causing the filling to be unqualified. [0004] In order to ensure product quality, one person is responsible for ...
