Abstract:
A liquid proportioning machine includes at least two liquid storage mechanisms for storing liquid, pump bodies for pumping liquid from the liquid storage mechanisms, and liquid discharge locations connected with liquid outlets of the pump bodies and ejecting liquid; and the liquid storage mechanisms are respectively connected with the corresponding pump bodies, and a regulating mechanism for keeping a proportion for the liquid discharge speeds of the pump bodies is arranged between the pump bodies. The pump body includes a rotating shaft, and the rotating shaft rotates to cause the pump body to pump and discharge the liquid; and the regulating mechanism includes a driving shaft driven by a driving mechanism to rotate, and the driving shaft drives the rotating shafts of the liquid storage mechanisms to rotate through a transmission mechanism and maintains a proportion for the rotating speeds between the rotating shafts. The driving shaft drives any rotating shaft to rotate through a first transmission mechanism, and a second transmission mechanism is arranged between other rotating shafts and the rotating shaft directly driven by the driving shaft. In the present invention, an automatic proportioning manner is adopted, so the proportion of various kinds of liquid does not need to be manually regulated, which improves the working efficiency and the proportioning accuracy, and then the quality of the product is improved. The entire device has a low cost and great market competitiveness.
