Abstract
The utility model relates to a high-precision quantitative liquid supply device. A step-by-step motor drives a piston in a liquid conveying cylinder to do the step motion via a deceleration driving device and a linear driving device, and materials in the liquid conveying cylinder is output by a control valve and a conveying pipeline. Because the stepping angle of the step-by-step motor is small, the step precision is high and uniform. Materials can be accurately and quantitatively supplied by supplying different step-by-step impulse signals to the step-by-step motor according to needs the utility model can be used for threads made by tobacco and added with essence and spice, the production lines of food, the production lines of chemical industries, laboratores, and flowmeter of the calibration and verification and occasions needed by accurate liquid feed.
Description
The utility model belongs to a kind of accurate quantitative liquid feeding body device, particularly relates to a kind of quantitative device for liquid of high accuracy that is applied in occasions such as adding essence spices, food production line, laboratory in the tobacco processing line.
The occasions such as demarcation, verification that add essence spices, food production line, chemical production line, laboratory and flowmeter in tobacco processing line all need accurate quantitative liquid feeding.The common methods of liquid feeding has measuring pump method, quantity tube method, pneumatic process etc. continuously at present.The measuring pump method is not suitable for tiny flow quantity, belongs to the pulsation feed, precision is low.The disclosed quantity tube method of CN1044390A, its feed ripple amplitude is big, and adopts air bladder valve regulation feed amount, and precision is also lower.The CN2226825Y utility model patent discloses the pneumatic process feeding device, and its expectation is added on the liquid material with pressure stable and pushes away its discharge, and with air bladder valve regulation flow.Though be better than the quantity tube method, because air pressure is difficult to constantly, be subjected to the control valve accuracy limitations again, the feed precision is still not high.
The purpose of this utility model is to provide a kind of high accuracy quantitative liquid feed device, and being implemented in various range of flows particularly all can accurate feed flow under the tiny flow quantity situation.
For achieving the above object, the technical solution adopted in the utility model is: the quantitative liquid feed device of a kind of high accuracy, motor is connected with the transfusion cylinder with transmission mechanism through deceleration, the transfusion cylinder is connected with woven hose by control valve, the transfusion cylinder is the tubulose tank body that piston is arranged in, used motor is a stepper motor, and control valve is connected with transfusion cylinder top and the bottom by pipe.
Adopt above technical scheme, after the output of stepper motor is converted into rectilinear motion, promote piston and make the straight line step motion, because the step angle of stepper motor is very little, therefore the stepping accuracy of piston is high and evenly, can reach every moved further 0.0001mm even small distance more, provides different step-by-step impulse sequences to stepper motor, just can allow the corresponding step number of its stepping as required, reach purpose accurate, quantitative liquid feeding.
Embodiment at the tobacco processing line perfuming further specifies below in conjunction with the utility model:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is a kind of structural representation of transfusion cylinder;
Fig. 3 is the another kind of structural representation of transfusion cylinder.
Embodiment: magnetic valve 4 is connected with transfusion cylinder 3 upper and lower sides by pipe.Piston 13 in the transfusion cylinder 3 is driven through reducing gear and 2 decelerations of straight-line transmitting actuation mechanism with after changing rectilinear motion into by the output of stepper motor 1.Transfusion cylinder 3 can adopt piston-rodless magnetic-type as shown in Figure 2, also can adopt piston rod thrust formula as shown in Figure 3.Transfusion cylinder shown in Figure 2 is made up of cylinder body 11, end cap 12, piston 13, connection slide block 14, two end cap 12 or cylinder sidewall porose 15 are used to connect woven hose, connection slide block 14 is contained in the cylinder outer wall corresponding to piston position, magnet 16 is housed in it, between piston 13 and cylinder body 11 inwalls sealing ring 17 is housed, inside wall of cylinder fineness is higher, sliding capability between sealing ring 17 and inboard wall of cylinder block is good, connect slide block 14 and drive in the slip of cylinder outer wall, and in cylinder, slide by bigger magneticaction drive ferromagnetic pistons by the straight-line transmitting actuation mechanism.What transfusion cylinder shown in Figure 3 was different with transfusion cylinder shown in Figure 2 is to adopt piston rod 18 to drive piston to slide in cylinder.Magnetic valve 4 is connected with magnetic valve 5, and magnetic valve 5 is connected with magnetic valve 6, and magnetic valve 6 links to each other with shower nozzle 7,8 by efferent duct, and magnetic valve 9 also links to each other with shower nozzle 7,8 by pipe, and compressed air PA provides atomizing pressure via magnetic valve 9 and pipe when fragrant for shower nozzle.4,5 of magnetic valves are connected to electro connecting pressure gauge 10.
During feed flow, according to adding the flow signal that incense prescription and ratio, belt claim, computer correspondence by this device of control provides the step-by-step impulse sequence of stepper motor, and the output of the stepper motor back of slowing down drives piston by the straight-line transmitting actuation mechanism and makes step motion, and the transfusion cylinder is exported the liquid of corresponding weight.Its fragrant process is: when piston stroking upward, essence is pumped into transfusion cylinder bottom by pipe 19 and magnetic valve 4, another passage and the magnetic valve 5,6 of the existing essence in cylinder top by magnetic valve 4 of infusing simultaneously enters shower nozzle, is compressed air atomizing and sprays in the pipe tobacco.When descent of piston, the essence of transfusion cylinder bottom enters shower nozzle by the magnetic valve 4,5,6 after commutating, and essence is stand-by by pipe and magnetic valve 4 suction transfusion cylinders simultaneously.If shower nozzle stops up, electro connecting pressure gauge 10 actions switch to standby shower nozzle by computer control magnetic valve 6,9 with pipeline.
