[0063] Working principle:

[0064] The raw materials are stored by the first storage tank 1, and are sent to the feeding mechanism 4 by the conveying assembly 3. After one-time screening, the raw materials are sent to the pressure mechanism 5 for processing. After processing, the raw materials are sent to the whole-grain mechanism 6 for final whole-grain processing by the conveying assembly 3, and the final whole-grain finished products are stored by the second storage tank 2. In the conveying assembly 3, the connection is completed by the adapter pipe 301, and the driving effect is achieved by the vacuum feeding machine 303 through force. The raw materials are pumped to the output end of the vacuum feeding machine 303 through the feeding hose 302 for waiting to be put. The vacuum feeding machine 303 is driven by the electric sliding rail 304, and the position of the vacuum feeding machine 303 is adjusted to realize the adjustment function of the feeding position of the vacuum feeding machine 303. The raw materials are put into the corresponding drop point of the flared channel 305 by the vacuum feeding machine 303.

The finished products are sent to the adapter pipe 301 position based on the slope structure of the processing chamber 502. After the raw materials enter the connecting channel 503 through the inlet channel 504, the raw materials are pushed between the upper pressure roller 506 and the lower pressure roller 507 in batches by the pressure assembly 505. The upper pressure roller 506 and the lower pressure roller 507 rotate in opposite directions to press the raw materials into a sheet shape. The sheet-shaped raw materials are further operated by the upper pressure roller 506 and the lower pressure roller 507, and are matched with the structure of the inclined channel 509 to contact the circular rotary cutter. The cutting effect is realized by the rotation of the center shaft of the cutting knife roller 508. The processing frame 601 receives the raw materials discharged from the flared channel 305. After internal processing is completed, the raw materials are transferred to the adapter channel 602. The adapter channel 602 of the feeding mechanism 4 is connected with the flared channel 305, and the adapter channel 602 of the whole-grain mechanism 6 is connected with the second storage tank 2.

The first driving motor 403 drives the stirring roller 404 to rotate, so that the raw materials can be continuously contacted with the coarse screen 401 in batches to be screened in turn. In the whole-grain mechanism 6, the final screening is realized by the fine screen 603, and the second mounting plate 604 provides support for the operation of the second driving motor 605. The driving shaft 606 rotates during the operation of the second driving motor 605, and exerts force on the shaft sleeve 608 to drive the roller body 607 to rotate. The adjustable cutter rollers can be sleeved on the surface of the driving shaft 606 according to the requirements. The sliding shaft 613 is forced by pulling the splicing plate 614 to extend or contract to a certain length. During the movement of the sliding shaft 613, the friction plate exerts force on the damping turntable 612 to further exert force on the other group of sliding shafts 613 to move to a certain position. The splicing between the cutter groups is completed by the cooperation of the buckle 616 and the card slot 615.The knife assembly is assembled to the inside of the adaptive mounting groove 609 to realize the adjustment function of the transverse and longitudinal spacing of the blade 611 in the adjustable knife roller, and then is adapted to the pressure mechanism 5 to ensure the whole grain effect and the flexibility of the whole grain work, and avoid the occurrence of the carding and the like.
