A kind of biliquid encapsulating metering system
Technical field
The utility model belongs to equipment of industrial product field, specifically relates to a kind of biliquid encapsulating metering system.
Background technology
The encapsulating machine is to cooperate electronic product, the equipment common equipment of embedding in batches, especially for the production of electronic products such as LED screen, requires encapsulating equipment can realize the accurate measurement of two or more raw material liqs mixing, proportioning mixing.In commercial production, adopt liquid gaging system to achieve the above object; Liquid gaging system adopts the gear type pump metering more on the market now; Dose the liquid material of material for containing solid, gear type pump use for a long time can cause the gear wear of gear type pump, and service life is shorter; Need often to change, otherwise the subsequent technique production process is impacted.
Therefore, design a kind of biliquid encapsulating metering system that can realize that different liquid material proportioning accuracy controls, service life are grown, the problem that the contriver faced just to above-mentioned present situation.
Summary of the invention
The utility model while is according to the bi-component liquid material of different proportion; Adopt two groups of different piston-type measurement systems of masuring room diameter; Realize the proportioning control of different liquid material through the high volume measurement mode of measuring accuracy, institute's employing masuring room is ceramic material, and is durable in use.
The technical scheme that the utility model adopted is a kind of biliquid encapsulating metering system, is made up of liquid tank, piston pump, masuring room, feeding pipe, discharging cushion valve and discharging surge chamber.Said liquid tank is communicated with the inlet of said masuring room; Said masuring room adopts ceramic material, and its piston size is just identical with the masuring room width; Said masuring room is communicated with the inlet of discharging surge chamber through feeding pipe; Said discharging surge chamber entrance is provided with the discharging cushion valve.
Further, said liquid tank, piston pump, masuring room, liquid-transport pipe-line, discharging cushion valve and discharging surge chamber respectively are two groups.
The beneficial effect of the utility model is:
1, the liquid tank of two component liquid material is communicated with one group of piston pump, masuring room, liquid-transport pipe-line, discharging cushion valve and discharging surge chamber respectively; Therefore; The bi-component liquid material of different proportion; Adopt two different cover piston-type measurement systems of masuring room diameter, guarantee the accurate discharging of liquid material respectively through the stroke of piston pump in masuring room, help realizing the accuracy control of different liquid material proportionings.
2, institute's employing masuring room is the high abrasion ceramic material, and is durable in use, and long service life need not frequent replacing.
3,, can guarantee the stability of liquid material discharging through discharging surge chamber and the design of discharging cushion valve.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.
As shown in Figure 1, a kind of biliquid encapsulating of the utility model metering system scheme drawing is made up of liquid tank 1, piston pump 2, masuring room 3, feeding pipe 4, discharging cushion valve 5 and discharging surge chamber 6.Said liquid tank 1 is communicated with the inlet of said masuring room 3; Said masuring room 3 adopts ceramic material; Said masuring room 3 is communicated with the inlet of discharging surge chamber 6 through feeding pipe 4; Said discharging surge chamber 6 entrance are provided with discharging cushion valve 5.
In above-mentioned specific embodiment, masuring room 3 is in vacuum state.The liquid material flows in masuring room 3 from the impetus of liquid tank 1 through piston pump 2, gets into discharging surge chamber 6 through feeding pipe 4 then.The impetus of piston pump 2 makes discharging cushion valve 5 upward movements that are positioned at discharging surge chamber 6 inlets simultaneously, finally embeds the outlet of discharging surge chamber 6, can guarantee the stability of liquid material discharging.The utility model while is according to the bi-component liquid material of different proportion; Adopt two different cover piston-type measurement systems of masuring room diameter; The stroke that promotes of volume through masuring room 3 and piston pump 2 is controlled the discharging situation of liquid material jointly respectively, helps realizing the accuracy control of different liquid material proportionings.In addition, adopt masuring room 3 to be ceramic material, durable in use, long service life need not frequent replacing.
