The specific embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As shown in Figure 2, the control setup of a kind of liquid medicine filling of the utility model embodiment, comprise filling control assembly 1, flow counter 3 and can pipeline 7, can pipeline 7 is provided with the adjustable control group of caliber 5, and filling control assembly 1 is adjusted the caliber of the adjustable control group 5 of caliber according to the different phase of pouring process.By the caliber of the adjustable control group 5 of filling control assembly 1 adjusting caliber, can realize the change of can pipeline 7 calibers, solve the precision problem of flow control, it is simple in structure, with low cost, and the speed of production of whole production line can not be affected yet.
In the present embodiment, the control group 5 that caliber is adjustable is for having the control group of two or more different tube diameters mozzles.It is preferably the pneumatic diaphragm valve of often opening, it can not close can pipeline 7, latus rectum is big in the time of can being made as unlatching, latus rectum is little when closing, latus rectum is little in the time of also can being made as unlatching, the big form of latus rectum when closing, filling control assembly 1 are according to the caliber of the adjustable control group 5 of the different phase adjustment caliber of pouring process, and the caliber that then can change can pipeline 7 is to adjust flow.Also be provided with the on and off switch assembly 6 that links to each other with filling control assembly 1 on the can pipeline 7, on and off switch assembly 6 is used for the keying of can pipeline 7, is the closed type pneumatic diaphragm valve, and control group 5 and on and off switch assembly 6 that caliber is adjustable are series on the can pipeline 7.In this structure, the effective drift diameter of can pipeline 7 should be greater than the little latus rectum of the adjustable control group 5 of caliber, could switch to less latus rectum at the big latus rectum of the adjustable control group 5 of caliber after, play the purpose that reduces flow.When having a plurality of filling control loop, and under the situation of the filling speed unanimity in each filling control loop, each control group in a plurality of filling control loop all only need be provided with a control element (as: electromagnetic valve), can control simultaneously, structure is simpler, and cost is lower.
As shown in Figure 3, the control setup of a kind of liquid medicine filling of another embodiment of the utility model, comprise filling control assembly 1, flow counter 3 and can pipeline 7, be in series with the control group that has different tube diameters more than two on the can pipeline 7, filling control assembly 1 is selected the control group conducting of different tube diameters according to the residing stage of pouring process; Perhaps be parallel with two above control groups on the can pipeline 7, filling control assembly 1 is selected the control group conducting of different tube diameters summation according to the residing stage of pouring process.
In the present embodiment, can pipeline 7 is provided with the on and off switch assembly 6 that links to each other with filling control assembly 1, the control group and the on and off switch assembly 6 that have different tube diameters more than two are the closed type pneumatic diaphragm valve, their parallel with one another being connected on the can pipeline 7 are closed or are opened by control assembly 1 control.In this kind structure, the effective drift diameter of can pipeline 7 should be more than or equal to the latus rectum sum of all control groups in parallel, could play the purpose that reduces fluid flow after closing wherein certain control group.
Among each embodiment, be equipped with manual control cock 8 on the can pipeline 7, can be by the open and close in the whole can of manual control cock 8 controls loop.
Control process: when connecting with on and off switch assembly 6 with the adjustable control group 5 of caliber is example.During the beginning can, control group 5 and on and off switch assembly 6 that caliber is adjustable are opened simultaneously, and filling speed is fast, and flow is big.When being filled to a certain degree (can pass through to set), the adjustable control group 5 of filling control assembly 1 control caliber is closed, so that soup is flow through by the adjustable control group 5 less latus rectums of caliber.Because of the latus rectum of the adjustable control group 5 of caliber reduces, the effective cross sectional area of can pipeline is diminished, thereby can reduce the influx of each components and parts, so but the can amount of accurately controlling medicinal liquid at the response time inner liquid medicine.When flow counter 3 reached the can amount, flow counter 3 was sent signal and is given filling control assembly 1 closing on and off switch assembly 6, and then finishes can.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.
