Wet mixing granulator, and solid preparation production line applying wet mixing granulator

Abstract

The invention provides a wet mixing granulator, and a solid preparation production line applying the wet mixing granulator. The wet mixing granulator comprises a material cylinder, a rotary shaft, a granulation cutter and a stirring paddle. The stirring paddle is fixed onto the rotary shaft; the rotary shaft is driven by a power device I to rotate; the granulation cutter is driven by a power device II to rotate; a first connecting rod is fixedly connected with the rotary shaft in a sleeved way; a first powder scraper blade pressing against an inner wall of the material cylinder is fixed to oneend of the first connecting rod; a second connecting rod capable of axially moving along the rotary shaft is arranged on the rotary shaft; a second powder scraper blade pressing against the inner wall of the material cylinder is fixed to one end of the second connecting rod; the first powder scraper blade is located on the upper end of the granulation cutter; the second powder scraper blade and the granulation cutter are located on the same height; the first powder scraper blade and the second powder scraper blade are arranged in a staggering way; a guide bar is arranged at one side, close tothe granulation cutter, of the interior of the material cylinder, and is located on the outer side of a cutting trace of the granulation cutter; the rotary shaft rotates to drive the first powder scraper blade and the second powder scraper blade to rotate circumferentially; when moving to one side of the granulation cutter, the second powder scraper blade presses against the outer side of the guide bar and moves in an extending direction of the guide bar.
