Water-based paint preparation production line

The invention discloses a water-based paint preparation production line, the dosage of water needing to be added is determined by an operator, and a lifting rod is pulled to drive a piston to be lifted upwards in a transfer barrel, so that air in the transfer barrel is compressed; a water storage bag located above the transfer barrel conveys water into the transfer barrel through pressure and gravity, the operator observes that the amount of output liquid reaches a preset threshold value through the scale label, then the piston is compressed again, the liquid water is outputted into the dilution barrel through the liquid outlet needle head, and thus the amount of water entering the diluting cylinder is constant, and the dilution degree of the water-based paint is ensured. 本发明公开了一种水性涂料制备生产线，通过操作人员确定好需要加入水的剂量，并通过拉动所述提升杆，带动所述活塞在所述转运筒内向上提升，从而压缩所述转运筒内的空气，使得位于所述转运筒上方的所述存水袋通过压强和重力将水输送至所述转运筒内，操作人员通过所述刻度标贴观察输出液体的量到达预设阈值，然后再次压缩所述活塞，将液体水通过所述出液针头输出至所述稀释筒内，从而使得进入到稀释筒的水量恒定，保证了水性涂料的稀释度。
