Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 3 A quantitative dispensing device includes a quantitative cylinder 1 and a power pump 2. The quantitative cylinder 1 is horizontally arranged. The power pump 2 is externally powered and has a corresponding external control switch. A transparent window 101 is provided on the outer surface of the quantitative cylinder 1 to facilitate observation of the liquid content inside the quantitative cylinder 1. The transparent window 101 is provided with a scale indicating the volume of the corresponding position inside the quantitative cylinder 1. A discharge pipe 3 is fixedly connected to the bottom of the quantitative cylinder 1. A first solenoid valve 301 is installed on the discharge pipe 3. An adjustable sleeve 4 that can move up and down is provided at the bottom of the discharge pipe 3.

[0025] like Figure 1 and Figure 3 An adjusting screw 5 is threadedly connected to the center of one end of the metering cylinder 1. An adjusting piston 501 is rotatably connected to the end of the adjusting screw 5 inside the metering cylinder 1. The adjusting piston 501 is used to divide the space inside the metering cylinder 1, forming a liquid storage chamber 102 and an adjusting chamber 103 inside the metering cylinder 1. The liquid storage chamber 102 is connected to the discharge pipe 3. A control handle 6 is fixedly connected to the end of the adjusting screw 5 outside the metering cylinder 1. The adjusting screw 5 can be easily rotated by rotating the control handle 6.

[0026] like Figure 1 and Figure 2An L-shaped bracket 7 is provided on one side of the metering cylinder 1. The horizontal end of the bottom of the L-shaped bracket 7 can be fixed to an external mechanism. A horizontal fixing plate 8 is fixedly connected to the top of the L-shaped bracket 7. A metering cylinder support frame 801 and a pump support frame 802 are fixedly installed on one side of the horizontal fixing plate 8. The metering cylinder 1 is fixedly installed on the metering cylinder support frame 801, and the power pump 2 is fixedly installed on the pump support frame 802, thus providing support for the metering cylinder 1 and the power pump 2.

[0027] like Figure 1 The power pump 2 is fixedly installed with a liquid inlet hose 9, and a liquid inlet nozzle 901 is fixedly installed at the bottom of the liquid inlet hose 9. By moving the liquid inlet hose 9, the liquid inlet nozzle 901 can be placed into the container storing liquid raw materials, so that when the power pump 2 is started, the liquid raw materials in the container can be sucked in through the liquid inlet nozzle 901.

[0028] like Figure 1 and Figure 3 The outlet of the power pump 2 is fixedly equipped with an outlet pipe 10. The end of the outlet pipe 10 away from the power pump 2 is fixedly installed on the top of the metering cylinder 1. A second solenoid valve 1001 is installed on the end of the outlet pipe 10 close to the metering cylinder 1. The first solenoid valve 301 and the second solenoid valve 1001 are both existing technologies, and their models are both 2W-32.

[0029] like Figure 1 and Figure 4 The top of the adjusting sleeve 4 is provided with a connecting ring 401, and a limiting ring 302 is fixedly installed on the outer surface of the discharge pipe 3. The bottom of the discharge pipe 3 passes through the limiting ring 302 and extends into the interior of the adjusting sleeve 4. A return spring 11 is fixedly connected between the limiting ring 302 and the connecting ring 401. The return spring 11 is sleeved on the outer surface of the discharge pipe 3.

[0030] When the adjusting sleeve 4 is moved upward, the container used for liquid material recovery can be moved horizontally to below the adjusting sleeve 4. Then, the adjusting sleeve 4 is released, and the return spring 11 extends to push the adjusting sleeve 4 downward. The bottom of the adjusting sleeve 4 can descend into the container. At this time, the liquid material flowing out from the discharge pipe 3 will directly enter the container through the adjusting sleeve 4. The liquid material will not fall outside the container. After the material is collected, the adjusting sleeve 4 is moved upward, and the container can be moved horizontally to remove the container from below the adjusting sleeve 4.

[0031] like Figure 1 and Figure 4The limiting ring 302 is fixedly connected to a limiting plate 12 on one side. The horizontal end of the bottom of the limiting plate 12 is located below the connecting ring 401, which can limit the maximum distance of the adjustment sleeve 4 to descend. The L-shaped bracket 7 is fixedly connected to a winding rod 13 on one side. When the liquid inlet hose 9 is not in use, it can be wound onto the winding rod 13. The winding rod 13 has multiple through holes 131.

[0032] The working principle of the quantitative feeding device provided by this utility model is as follows:

[0033] When it is necessary to quantitatively extract liquid raw materials, the power pump 2 draws in the external liquid raw materials and delivers them into the metering cylinder 1 through the liquid inlet hose 9. After the liquid raw materials fill the storage chamber 102, the second solenoid valve 1001 is closed, the power pump 2 is turned off, and the first solenoid valve 301 is opened. The liquid raw materials that fill the storage chamber 102 can then be delivered to the external container through the discharge pipe 3 and the regulating sleeve 4 to complete the quantitative extraction.

[0034] When the adjusting screw 5 is manually rotated in different directions, the adjusting screw 5 drives the adjusting piston 501 to move in different directions inside the metering cylinder 1, adjusting the volume inside the liquid storage chamber 102. Each time a quantitative material is taken, the amount taken is equal to the volume inside the liquid storage chamber 102.

[0035] Compared with related technologies, the quantitative feeding device provided by this utility model has the following beneficial effects:

[0036] This invention uses a rotating adjusting screw 5 to drive an adjusting piston 501 to move inside a metering cylinder 1, which can adjust the volume of the liquid storage chamber 102. Each time a sample is taken, the sampled liquid material fills the liquid storage chamber 102 completely, and then enters an external container through a discharge pipe 3 to complete the quantitative extraction. This allows for the quantitative extraction of liquid material with different contents by adjusting the volume of the liquid storage chamber 102 according to actual needs.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
