The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Such as Fig. 1 to 3, the automatic material-dispensing system of the Wood-plastic material of present embodiment comprises 10 raw material cabin 1(wherein: 3 are used for the major ingredient storehouses of three kinds of main materials of carrying, 7 auxiliary material storehouses that are used for seven kinds of auxiliary materials of carrying), scroll feeder 2, static batching weighing storehouse 3, mixing agitator 4, industrial computer, main electrical control cabinet etc.
Scroll feeder 2 comprises: major ingredient, auxiliary material scroll feeder, static batching weighing storehouse 3 comprises: major ingredient, the static batching weighing of auxiliary material storehouse, mixing agitator 4 comprises: first, second, and third mixing agitator.
The major ingredient scroll feeder is connected on the bottom discharge mouth in each major ingredient storehouse, the auxiliary material scroll feeder is connected on the bottom discharge mouth in each auxiliary material storehouse, the static batching weighing of major ingredient storehouse links to each other with the discharging opening of each major ingredient scroll feeder respectively, the static batching weighing of auxiliary material storehouse links to each other with the discharging opening of each auxiliary material scroll feeder respectively, major ingredient, the static batching weighing of auxiliary material storehouse is provided with LOAD CELLS, the first mixing and blending machine links to each other with the bottom discharge mouth in the static batching weighing of major ingredient storehouse, the second mixing and blending machine links to each other with the bottom discharge mouth in the static batching weighing of auxiliary material storehouse, the 3rd mixing and blending machine and first, the bottom discharge mouth of the second mixing and blending machine links to each other, granulator links to each other with the bottom discharge mouth of the 3rd mixing and blending machine, and host computer is suitable for arranging the dosage of each raw material, proportion parameter and reception are from the feedback signal of described LOAD CELLS; Main electrical control cabinet links to each other with described host computer, is used for the duty of each scroll feeder of control, each mixing and blending machine; Described scroll feeder is by being suitable for realizing that the reinforced variable-frequency motor of speed change drives.The bottom discharge mouth in described each static batching weighing storehouse is provided with the blow-off valve by described main electrical control cabinet control.
