[0021] Working principle:

[0022] This device is connected to an external power source for powering drive motor 1-2-3, air pump 1-2, and drive motor 2-5-2. Drive motor 1-2-3, air pump 1-2, and drive motor 2-5-2 are all existing technologies and are purchased externally, so they will not be described in detail.

[0023] In operation, the raw material is poured into the feeding hopper 2-1 through the inlet 2-2. The drive motor 2-3 is energized, driving the spiral plate 2-6 to rotate via the rotating shaft 2-5. The rotation of the spiral plate 2-6 moves the raw material, which is then extruded through the extrusion port 2-7 onto the arc-shaped pressure plate 3-5-6. The two pressing rollers 3-5-1 are pressed against each other by the action of spring 3-3. The drive motor 3-5-2 is then energized, and the two pressing rollers 3-5-1 are positioned opposite each other. The rotation of the rollers causes the two crushing rollers 3-5-1 to rotate relative to each other. The rollers 3-5-1, rotating, crush the raw material through the extrusion grooves on the arc-shaped pressure plate 3-5-6. The crushed tablets move backward and fall onto the crushing plate 1-5, separating the tablets from the excess raw material. The tablets then move downward along the crushing plate 1-5. Powering the air pump 1-2 draws in air and sends it into the air collection pipe 1-3, from which it is then ejected from the nozzle 1-4. The ejected gas can then be used to clean the sliding tablets. The tablets are separated from the excess raw materials. The mass of the excess raw materials is less than that of the tablets. The gas blows the excess raw materials into the other side of the baffle plate 1-6 and collects them at the bottom of the outer shell 1-1. At the same time, the tablets fall on the buffer pad 1-7 to cushion them and prevent them from breaking. They are then collected through the discharge port 1-8. The flow rate of the gas ejected from the jet nozzle 1-4 is calculated by a computer. When it is necessary to roll small-diameter tablets, the countersunk bolt 3-5-7 is loosened to remove the arc-shaped pressure plate 3-5-6 in sequence. The two rolling rollers 3-5-1 are driven to push against each other again by the action of spring 3-3. At this time, the extrusion groove 1 set by the rolling roller 3-5-1 can roll small-diameter tablets. After the countersunk bolt 3-5-7 is unscrewed, the sealing plate 3-5-5 is pushed upward by the action of spring 3-5-4 and pushes against the fixing hole 3-5-3. This can block the fixing hole 3-5-3 and prevent raw materials from entering the fixing hole 3-5-3 and clogging it.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
