[0002] All vertical liquid filling machines are equipped with feed liquid tanks. The feed liquid tanks of existing vertical liquid filling machines generally do not have precise liquid level control devices. They usually use the overflow structure of float valves, and the control accuracy is not high. The height of the liquid level has a certain influence on the filling speed and filling accuracy. For the items that require high filling accuracy, the ordinary vertical liquid filling machine cannot meet the requirements.

Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:
[0013] A vertical filling machine material box liquid level control device, such as figure 1 , figure 2 As shown, it includes a liquid material tank 1, a sliding column 2, a magnetic switch 3, a floating ring 4, an annular magnetic block 5 and a control part 6, and the lower end of the sliding column 2 is vertically fixed and installed on the liquid material tank through a fixing nut 8. 1, and the sliding column 2 is located in the liquid material tank 1, and the upper end of the sliding column 2 is provided with an upper limit ring 7. The sliding column 2 is a hollow tube, and the sliding column 2 is spaced along the axial direction. An upper limit magnetic switch 31, a lower limit magnetic switch 32 and an alarm magnetic switch 33 are provided. The three magnetic switches 3 are all electrically connected to the control part 6. The annular magnetic block 5 is...

A liquid level control device for a liquid storage bin of a vertical filling machine comprises the liquid storage bin, a slide column, three magnetic sensitive switches, a floating ring, an annular magnet and a control component, wherein the slide column which is a hollow tube is vertically and fixedly mounted at the bottom of the liquid storage bin and positioned in the liquid storage bin, the three magnetic sensitive switches are axially arranged in the slide column at intervals and electrically connected with the control component, the annular magnet is inlaid in the floating ring, a combination of the floating ring and the annular magnet are sleeved on the slide column, and an inner hole of the annular magnet is larger than the outer diameter of the slide column and sleeved on the slide column. The liquid level in the liquid storage bin is detected by the floating ring inlaid with the annular magnet and converted by the corresponding magnetic sensitive switch to corresponding electrical signals, the electrical signals are sent to the control component for signal processing, and then a corresponding prompt is sent out. By the means, the corresponding signal prompt can be sent to an operator, so that the liquid level in the liquid storage bin is effectively controlled, and stable filling speed and stable filling precision are guaranteed.
