Description
The utility model relates to a kind of microcomputer numerical control liquid quantitatively filling apparatus, belongs to liquid filling device.
Existing liquid quantitative filling equipment, its intrinsic canning means defines its structure, and its canning means is that earlier liquid to be injected a volumetric standard quantitative, and liquid that again will the amount of reserving is discharged, and pours in the packing container, and there is following defective in this filling apparatus:
1, inefficiency is carried out in quantitative and can in two steps;
2, quantitative accuracy is difficult for guaranteeing, quantitatively specification is difficult to adjust;
3, complicated in mechanical structure, manufacturing cost is higher, inapplicable medium-sized and small enterprises.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and provides a kind of quantitatively accurate, and is simple in structure, high efficiency, the microcomputer numerical control liquid quantitatively filling apparatus of quantitative manner novelty.
The purpose of this utility model is achieved in that it comprises computer control system, D.C. regulated power supply.Also be provided with the constant device of liquid level, resistance of ducting adjusting mechanism, electromagnetic valve actuating gear.The constant device of liquid level is made of constant voltage jar, float valve, afloat contact, upper limit contact, lower limit contact, float valve is positioned within the constant voltage jar, arrange up and down and lay respectively at constant voltage jar one side and microcomputer links in upper limit contact, afloat contact, lower limit contact, the constant device of whole liquid level places the top of pipeline.Resistance of ducting adjusting mechanism constitutes by adjusting flow valve, and adjustment flow valve and solenoid valve are in series and are positioned on the fluid pipeline.In order to make system controlled by computer freely, the utility model drives with D.C. regulated power supply.The output terminal of D.C. regulated power supply links with microcomputer, microcomputer output control system respectively, the work of the direct control electromagnetic valve of output control system, and microcomputer links by output control system and solenoid valve.
Principle of work of the present utility model is: according to hydromechanical theory, the flow of liquid equals the long-pending of flow velocity, circulation area and time, be that Q=V.A.t. is in a definite system, as make liquid level, pressure keep constant, then the flow velocity V of liquid is a constant, therefore flow Q is the function of time t, so just can control filling device by control filling time t, and the utility model is realized goal of the invention by this principle.
Compared to existing technology, the utlity model has following advantage:
1, owing to improved the quantitative manner of existing quantitative filling machinery, high efficiency is finished in the quantitative and can of this device synchronously;
2, adopt system controlled by computer, multiple functional, the scope of application is extensive;
3, reasonable in design, quantitatively specification is adjusted arbitrarily, and it is many to be adapted to product category, and the enterprise that can gauge lattice are many uses.
The drawing explanation of accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the computer system control theory diagram.
Fig. 3 is the float valve structural representation.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Among the figure, total valve (1), float valve (2), constant voltage jar (3), computing machine (4), canned gauge tap (5), liquid outlet (6), solenoid valve (7), adjustment flow valve (8), lower limit contact (9), upper limit contact (10), afloat contact (11), valve body (12), spool (13), O-ring seal (14), buffer spring (15), sliding spring seat (16), stop nut (17), float (18), inlet (19).
Control System of Microcomputer of the present utility model (4) adopts single-chip microcomputer, and single-chip microcomputer links with spacing contact (9), (10), afloat contact (11) up and down, also is connected with control can switch (5), in order to control can amount.Total valve of the present utility model (1) is arranged on the pipeline, the top that constant voltage filling (3) is positioned at pipeline communicates with pipeline, float valve (2) is made up of valve body (12), spool (13), O-ring seal (14), buffer spring (15), sliding spring seat (16), stop nut (17), float (18), be installed in constant voltage and irritate in (3), spacing up and down contact (9), (10) and afloat contact (11) are arranged on the side that constant voltage is irritated (3).Adjust flow valve (8) and be connected in series on the fluid pipeline with solenoid valve (7), the end of fluid pipeline is provided with liquid outlet (6), and the front end of input duct is inlet (19).
The implementation procedure that the utility model liquid level is constant is as follows: when the liquid in the constant voltage jar flowed out, liquid level descended, and float descends thereupon and drives spool and descends, inlet is opened, and the opening of liquid on valve body wall flows into the constant voltage jar, if liquid outlet quantity is greater than the feed liquor amount, it is many that liquid level descends, and then the spool slippage is big, and the circulation bore increases, otherwise liquid level rises, float drives spool thereupon and rises, and the circulation bore is reduced gradually, and the feed liquor amount also reduces, until with the inlet sealing, stop feed liquor.Thereby liquid level is fluctuateed within the specific limits, keep relative steady state.
The effect of D.C. regulated power supply is to guarantee when power supply is unstable, and computing machine and solenoid valve be operate as normal reliably all, and it is minimum that the dispersiveness of mechanical action is reduced to, to guarantee filling accuracy.
Groundwork process of the present utility model is as follows:
Liquid is entered constant voltage jar (3) and keeps certain liquid level by valve (1) and float valve (2) by high-order fluid reservoir or water pump.The canned time is imported computing machine (4) by materials calibration and sets.When below container is placed on liquid outlet (6), filling control switch (5) closure, computing machine (4) is received signal opens solenoid valve (7) by driving circuit and output control circuit, and the can pilot lamp is bright, and the time of presetting then, valve, lamp are closed simultaneously, the full pilot lamp of container is bright, and switch behind the extracting container (5) disconnects, and pilot lamp extinguishes, counter adds " 1 ", finishes a pouring process.When liquid level low excessively, when lower limit gauge tap (9), (10), (11) closure, computer instruction alarm lamp and hummer synchronous flashing are rung, and make unit filling time in can just prolong former fix time 10%, the unit of can is all temporary transient interrupts recovering operate as normal after the lower limit gauge tap disconnected for 5 seconds.If all unit all quit work back 15 seconds, the lower limit gauge tap does not disconnect yet then that computing machine changes the tail washings bottling condition over to, according to the container number of can revise automatically the filling time with compensation because the quantitative error that liquid level descends and causes.
