Description

Upward rotary type tablet screening machine for paliperidone palmitate bulk drug Technical Field The utility model belongs to the technical field of tablet processing and production, and particularly relates to an upward rotation type tablet screening machine for paliperidone palmitate bulk drug. Background Paliperidone palmitate is a benzisoxazole antipsychotic, and during the production process of the bulk drug, the paliperidone palmitate needs to be screened to ensure the quality of the product. In the process of screening the bulk drug, a paliperidone palmitate bulk drug upward rotary screening machine is needed. The existing paliperidone palmitate bulk drug upward rotation type screening machine is usually composed of a main body frame, a base, a supporting column and a screening box. The bottom of the screening box is provided with a feed inlet, a screening mechanism is assembled in the screening box, a motor drives a rotating shaft to drive stirring blades and the upward-rotation type screen to operate synchronously, and the downward-rotation type screen is arranged below the stirring blades. One side of the device is provided with a discharge hole, so that the classification and collection of the bulk drugs with different particle sizes are realized. The utility model discloses a convenient-to-use upward-rotation type sheet screening machine, which comprises a sheet screening machine body, a movable plate, a feeding pipe and a discharging pipe. The utility model starts the screening feeding component by arranging the control box, so that the screening feeding component screens and stably feeds materials, the problem that the existing upward rotation type screening machine can be used for adjusting the height in use, and the bending down of workers is avoided, thereby being convenient for users to use the upward rotation type screening machine, but in actual use, as the feeding port of the upward rotation type screening machine is positioned below, the material is upwards output to remove dust, so that the material is easily accumulated at a feed inlet of the upward rotation type screening machine in large quantity in use, the dust removal efficiency of the material is easily reduced when the upward rotation type screening machine outputs, and the situation is reduced by a plurality of times of small increases of a user, but the work intensity of workers is certainly increased, and the use effect of the upward rotation type screening machine is reduced. Based on the above, the existing paliperidone palmitate bulk drug upward rotary screening machine is easy to accumulate a large amount of raw materials at the feed inlet, thereby causing blocking phenomenon.
