[0024] As shown in Figure 1-2, a grinding device for tablet production includes a grinding box 1. A feed port 2 is provided at the upper end of the grinding box. The material to be ground enters the grinding box from the feed port. Two grinding rollers 3 are symmetrically provided in the grinding box. The two grinding rollers are connected to a drive motor. The two drive motors drive the two grinding rollers to rotate. The two grinding rollers rotate in opposite directions, thereby grinding the material. Under the action of gravity, the material enters the feed port between the two grinding rollers for grinding. Each grinding roller is provided with a cleaning brush 4 on the side of the grinding box body close to the grinding box. The cleaning brush includes a cleaning rod 401 And the brush head 402, the cleaning brush can brush off the residual material attached to the grinding roller to ensure the grinding quality. Two discharge channels 8 are symmetrically provided below the two grinding rollers, and the ground material falls into the discharge channel. Each discharge channel is provided with a scraper device 9, and the scraper device scrapes the material to the bottom of the discharge channel. A dividing device is provided below the two discharge channels, and the material flows from the discharge channel into the dividing device. A storage box 14 is provided below the dividing device, and the material flows into the storage box after being screened by the dividing device.

[0025] There are mounting holes on both sides of the grinding box. Each cleaning rod is arranged in the mounting hole. The cleaning rod can slide in the mounting hole. A fixing block 5 is provided above the mounting hole. The fixing block is fixedly connected to the outer wall of the grinding box. A positioning screw 6 is slidably connected to the fixing block along the height direction of the grinding box. The cleaning rod is provided with a strip hole 4011 matching the positioning screw along the length direction. A positioning nut 7 is provided on the positioning screw. The positioning screw passes through the fixing block and the strip hole in turn to fix the cleaning rod. The positioning screw and the positioning nut are locked together to fix the cleaning rod on the grinding box. The cleaning rod and the brush head are detachably connected by bolts. The brush head will be worn after a period of use. Regular replacement of the brush head can ensure the cleaning quality of the cleaning brush.

[0026] Each scraper device includes two rotating shafts and two closed-loop chains 901. The two rotating shafts are rotatably connected to the two ends of the grinding box. Two sprockets 902 are fixedly sleeved at both ends of each rotating shaft. The two chains are respectively sleeved on two pairs of sprockets on the same side. The chains are connected to the sprockets for transmission. One of the rotating shafts is connected to a transmission motor. Scraper plates 903 are evenly spaced between the two chains. The lower end of each scraper plate is in conflict with the surface of the discharge channel. The transmission motor drives the sprocket to rotate, and the sprocket drives the chain to rotate, thereby driving the scraper plate on the chain to move. The scraper plate can scrape off the residual material attached to the surface of the discharge channel, thereby effectively improving the grinding efficiency. Each scraper plate is detachably connected to the two chains by bolts. The scraper plate will also wear out after long-term use.

After the material enters the distributing box, the vibration motor drives the distributing box to vibrate, which can quickly screen the ground material into the storage box. The storage box is arranged between the two bases, and the material can fall directly from the distributing box into the storage box. A handle is provided on one side of the storage box, which is convenient for the operator to move the storage box. Four wheels are provided at the lower end of the storage box to facilitate the operator to push the storage box.

[0028] How it works

[0029] The material to be ground enters the grinding box from the feed port, and the material falls between the two grinding rollers for grinding. The ground material falls into the discharge channel, and the cleaning brush brushes off the remaining material on the grinding roller, and also falls into the discharge channel. The scraping device scrapes the material on the discharge channel to the bottom of the discharge channel, and the material falls from the discharge channel into the distribution box. The vibration motor drives the distribution box to vibrate, and the material that meets the standards falls into the storage box from the sieve holes at the bottom of the distribution box. The operator moves the storage box to move the qualified, ground material to the next processing flow.
