Therefore, the base device 1 is beneficial to expanding the operation range of the forming machine of the present invention.

[0068] Preferably, as Figure 8 shown in the figure, the feeding device further includes a second stirring bin 67. The second stirring bin 67 is vertically arranged with respect to the stirring bin 62. The middle part of the second stirring bin 67 is connected to the outlet of the stirring bin 62.
