[0040] The use method and advantages of the present invention: When the acetaminophen phenanthellamine granule preparation device is used, the working process is as follows:

[0041] When in use, firstly, put the acetaminophen and phenanthene raw materials into both sides of the box body 31, and then start the motor 32, the motor 32 drives the rotating rod 36 to rotate, the rotating rod 36 rotates to drive the bevel gear 1 37 on the surface to rotate, when the bevel gear 1 37 rotates, it drives the meshing bevel gear 2 39 to rotate, the bevel gear 2 39 rotates through the rotating rod 38, when the rotating rod 38 rotates, it drives the protrusion 313 to rotate, when the protrusion 313 rotates to the upper and lower positions, it squeezes the square frame 312 to move up and down inside the rectangular frame 310, and when the protrusion 313 rotates to the left and right positions, it passes through the square frame 31 2. Extrude the rectangular frame 310 so that it slides left and right inside the double slide groove 33, so that the connecting rod 311 fixed on the surface of the square frame 312 will form a reciprocating rectangular motion. The connecting rod 311 will drive the upper crushing plate 34 to move back and forth inside the box body 31, and extrude the raw materials through the lower crushing plate 35 to achieve the pretreatment effect without destroying the molecules inside the aminophenol and pheniramine raw materials. According to the different extrusion forces and the different spacings between the upper crushing plate 34 and the lower crushing plate 35, the extrusion effects are different and the pretreatment forces are also different.

[0042] Then the pretreated raw material will fall into the interior of the crushing box 21 and be crushed by the crushing blades 22, and then enter the interior of the machine body 1 through the discharge port 4, and at the same time, the driving motor 51 and the air pump 61 will be started, and the driving motor 51 drives the rotating rod 52 to rotate, and the rotating rod 52 rotates to drive the gear 53 to rotate, and the two gears 53 mesh and rotate relative to each other, and at the same time drive the two squeezing rollers 54 to rotate relative to each other, and when the semicircular grooves 55 opened on the surfaces of the two squeezing rollers 54 squeeze the raw materials relative to each other, at the same time, the squeezing rollers 54 will drive the side squeezing blocks 64 to rotate, and the squeezing blocks 64 will squeeze the sliding rod 65, and the sliding rod 65 will slide inside the T-shaped pipe 62, and at the same time drive the side pressing air valve 67 to slide, so that the T-shaped pipe 62 is connected with the air cavity 63, and at this time, the air pump 61 will inflate the air cavity 63 through the T-shaped pipe 62, and at the same time, the squeezing rollers 54 will drive the internal connecting pipe 57 to rotate, and the connecting pipe 57 drives the connecting pipe 81 to rotate, and the connecting pipe 81 is connected. When the connecting pipe 1 81 rotates, the triangular protrusion 1 82 on the side first squeezes the triangular protrusion 2 85. When the triangular protrusion 2 85 is squeezed, it drives the sliding pipe 83 to slide on the surface of the connecting pipe 2 84. When the connecting pipe 2 84 is completely docked with the connecting pipe 1 81, the connecting pipe 2 84 drives the internal fixed needle tube 86 to slide inside the connecting pipe 2 84, and at the same time passes through the rubber sheet 88 inside the connecting pipe 2 84, so that the gas in the air cavity 63 is transmitted to the sliding pipe 83 through the needle tube 86, and then transmitted to the inside of the connecting pipe 1 81 through the sliding pipe 83. The connecting pipe 57 inflates the inside of each semicircular groove 55 through the connecting pipe 1 81, and puts pressure on the high-density rubber 56, so that the extruded particles are fuller. Then, after the connecting pipe 1 81 rotates around the sliding pipe 83, the gas in the connecting pipe 57 will leak out, and then the high-density rubber 56 will recover. At the same time, the squeezed particles will be easier to detach, which is convenient for collection.

[0043] At the same time, when the rotating rod 1 52 rotates, it is connected to the rotating rod 2 74 through the transmission belt 73. The rotating rod 2 74 rotates inside the support block 75 and drives the Z-shaped rod 76 to rotate. When the Z-shaped rod 76 rotates, the belt-shaped arc slider 78 rotates inside the arc slide groove 77 and pushes the arc slide groove 77 to make an arc-shaped reciprocating motion on the upper surface of the support block 75 through the semicircular rod 79. When the semicircular rod 79 reciprocates in an arc, it squeezes the inclined screen 72 to make it vibrate. The inclined screen 72 moves through the telescopic rod 71. When the inclined screen 72 vibrates, the crushed materials produced during granulation are separated from the particles, and the waste materials can be further recycled.
