[0027] When the scraping block 6 actually performs the scraping operation, the scraping block 6 moves towards the inner wall of the discharge pipe 4 under the action of the scraping cylinder 5, so that the space between the scraping block 6 and the discharge pipe 4 is extruded, and because the scraping block 6 is completely sealed with the inner wall of the discharge pipe 4, the material in the discharge pipe 4 can be extruded and discharged, and as the scraping block 6 is completely attached to the inner wall of the discharge pipe 4, the material in the sealed space is completely scraped and extruded to fall into the distribution box 1 for distribution.
[0028] In combination with Figure 5 and Figure 6 , the first connecting plate 7 is arranged between the storage box and the discharge pipe 4, the first connecting plate 7 is provided with the first passing groove 8 for passing the material, and the blocking unit is arranged in the first passing groove 8.
[0029] The blocking unit comprises a blocking plate 9 made of a rectangular plate of food-grade PP material, the edge of the plate body is rounded to avoid scratching the inner wall of the clamping groove when sliding, the first clamping groove 10 is formed in the side wall of the first passing groove 8, the blocking plate 9 is inserted into the first clamping groove 10, the blocking plate 9 is connected with the first clamping groove 10 through a plurality of first springs 11 for providing elastic force, and the lower end of the blocking plate 9 is fixedly connected with the pushing plate 12.

When the scraping block 6 ascends and resets, it slides reversely along the inclined groove, generates slight counterclockwise swing, further cleans the residual ingredients adhered to the scraping plate itself, and avoids secondary pollution.

[0038] When the scraping block 6 moves upward after scraping the inner wall of the discharge pipe 4, the scraper 26 of the second scraping unit is already attached to the lower end of the scraping block 6 under the driving of the push rod 27, the scraper 26 is radially extruded with the surface of the scraping block 6, cooperates with the scraping block 6, and completely removes the residues adhered to the surface of the scraping block 6, so that the ingredients adhered to the lower end of the scraping block 6 due to the scraping operation can be scraped, when the scraper 26 returns to the original position, the first wobble block 38 arranged on the connecting block 33 contacts the first wobble block 38, drives the third spring 37 to deform, drives the scraper 26 to wobble in the vertical direction, so that the ingredients adhered to the scraper 26 fall off, and the accuracy of the preparation is further ensured.
