Preferably, the digital control device 60 can be connected to an operation unit 200 through a wired or wireless manner. If it is wired, the operation unit 200 is a computer. If it is wireless, the operation unit 200 may be a handheld mobile device, such as a mobile phone or a tablet.

The following are the action steps used in the present invention:

As shown in FIG. 4 to FIG. 5, firstly placing the container 101 on the mobile platform 30 and detecting that the container 101 has been positioned through the detector 31 can drive the first power source 433 to use the first crank link Group 43 pulls the displacement plate 41 to the left in the figure, so that the mobile platform 30 is horizontally displaced relative to the side seat 20, and then the container 101 is pulled below the liquid outlet pipe 103. Then, the second power source 443 is actuated to The second crank connecting rod group 44 is used to push up the ejector rod 42 so that the container 101 is closer to the end of the liquid outlet tube 103 as the mobile platform 30 rises, so that when the liquid begins to be dispensed, the generation of foam can be reduced.

As shown in FIG. 2, FIG. 6 and FIG. 7, after the container 101 is positioned, the operation unit 200 is used to input the volume value of the required liquid in order to transmit a digital signal to the digital control device 60. After receiving the signal command, Then, the motor 53 is driven to use the screw 51 to drive the lifting plate 54 to rise, so that the cone lifter 102 is lifted. Then, the motor 53 starts to reverse and the lifting plate 54 is lowered by a corresponding stroke according to the required capacity value, and The liquid is dispensed into the container 101 through the liquid outlet pipe 103 to achieve the effect of automatically controlling the liquid supply amount.

Therefore, the dispensing machine capable of automatically controlling the liquid supply amount of the present invention is directly controlled and operated by the operation unit 200, and can quickly supply the liquid bottle 100 to the container 101, and when the single liquid supply amount does not reach the target value, It is also possible to automatically convert the number of operations of the packager 102 through the digital control device 60 to complete the required capacity value. For example, if the target value is 20cc and only 10cc of liquid can be discharged in a single stroke, the digital control device 60 can automatically convert and drive the dispenser 102 to operate twice, and the same value can be achieved.

As mentioned above, the dispenser capable of automatically controlling the liquid supply amount according to the present invention can achieve the purpose of automatic liquid discharge, and avoid the manual inconvenience of repeatedly adjusting the scale, and can be applied to the dispensing range of various liquids, and has better practicability. .
