[0002] An existing patent (publication number: CN216757182U) discloses a screening equipment for pharmaceutical production. It includes a base frame and a sieve frame. The bottom of the sieve frame has multiple sieve holes, and one side of the sieve frame has multiple mounting holes. A horizontal shaft is rotatably mounted in each of these mounting holes. Multiple stirring rods are fixedly mounted on the outside of the horizontal shaft, and a first bevel gear is fixedly connected to the right end of the horizontal shaft. Two mounting plates are fixedly mounted on the right side of the sieve frame, and a common rotating shaft is rotatably mounted on the side of the two mounting plates that are close to each other. A transmission gear and multiple second bevel gears are fixedly sleeved on the outside of the rotating shaft. However, this device, where "the bottom of the sieve frame has multiple sieve holes," relies on the sieve frame above the base frame for screening. Because the sieve frame requires manual feeding, if there is a large amount of raw material to be screened, the operator needs to manually feed the material into the sieve frame in batches, which is inconvenient and affects the efficiency of the equipment. Summary of the Invention

If there is too much raw material, it is fed into the storage hopper, and then the conveying motor on the upper part of the conveying cylinder drives the spiral shaft to rotate. The spiral shaft drives the spiral blades inside the conveying cylinder to rotate, while the pharmaceutical raw materials at the bottom of the storage hopper are conveyed in batches through the conveying cylinder to the inside of the roller screen for screening. During this process, there is no need for the operator to manually feed the materials in batches, avoiding the accumulation of raw materials inside the roller screen, thereby increasing the working efficiency of the equipment.
