Sustained release tablet tabletting device and method

Abstract

The invention discloses a sustained release tablet tabletting device and method. The sustained release tablet tabletting device comprises a platform, a tabletting opening is reserved in the platform, an ejection block is vertically arranged in the tabletting opening in a sliding manner and connected with a lifting pipe through an ejection rod, a motor is arranged at one end of the platform, and the motor is in driving connection with a material pushing block through a screw; the material pushing block is connected with excess material boxes at the two ends of the platform through pulley systems; and the side walls, facing the platform, of the excess material boxes are movable walls, the lower edges of the movable walls are hinged to the excess material boxes, ring springs are arranged at the hinged positions, the upper edges of the movable walls are bent outwards, raw material boxes are arranged above the two ends of the platform respectively, the side walls of the raw material boxes are connected with shifting rods through connecting rods, and the bottoms of the raw material boxes are transversely and slidably connected with transverse plates. The transverse plates are downwards and fixedly connected with pull rods, tension springs are connected between the pull rods and the raw material boxes, a tabletting plate is arranged above the platform and connected with a tabletting column and a lifting rod, a tablet pushing plate is arranged at one side of the platform, and a collecting box is arranged at the other side of the platform. The device is uniform and stable in filling, can timely return redundant raw materials to the raw material boxes, and saves the raw material cost.

Description

technical field [0001] The invention belongs to the technical field of sustained-release tablet compression, and in particular relates to a sustained-release tablet compression device and method. Background technique [0002] Sustained-release tablets are a type of tablet that prolongs the release and absorption of drugs in the body by appropriate methods, thereby prolonging the drug’s action time. In the production of sustained-release tablets, granules or powder need to be compressed into the final product sustained-release tablets by tableting equipment , the existing tablet press equipment is divided into single-punch tablet press machine, flower basket tablet press machine and rotary tablet press machine, but the existing equipment generally has the problems of unstable filler and excessive raw materials that cannot be recovered in time, uneven and stable filler will cause The quality of tablet pressing is not enough, and the raw material recovery is not timely and will...
