[0040] Example: such as Figure 1-10 As shown, the present invention provides a kind of technical scheme, a kind of preparation method of PLA polylactic acid of degradable straw raw material, comprises the steps:
[0041] S1: Feeding: Pour the raw materials sequentially onto the surface of the raw material stacking plate 602 located on the top of the frame 1, the weight of the raw materials will press the raw material stacking plate 602 downward, and the oval slider 605 and the shading baffle 614 will follow the raw material stacking plate 602 descend together, the light emitted by the laser lamp 617 is displayed through the light-transmitting hole 615, and the feeding is stopped;
[0042] S2: Overturning and unloading: After all the raw materials are added, the oval slider 605 moves down to the inside of the circular channel 612, the raw material accumulation plate 602 and the oval slider 605 rotate at the same time, and the surface of the raw material accumulation plate 602 ...
