Spiral ribbon-free vibrating pharmaceutical powder mixing device

Abstract

The invention discloses a spiral ribbon-free vibrating pharmaceutical powder mixing device, relating to the field of pharmaceutical production equipment. The spiral ribbon-free vibrating pharmaceutical powder mixing device comprises a base, an elastic support frame, a vibration source mechanism, an elastic transition connection assembly and a mixing tank, wherein the elastic support frame is composed of a sliding guide column, a hinged block, a spring I, a lower bottom plate and an upper cover plate, the vibration source mechanism is composed of a motor and a cam, the motor is fixedly mountedon the base, the cam is fixedly connected with an output shaft of the motor, the elastic transition connection assembly is composed of a rotating wheel, a sliding connecting rod and an elastic hingedblock, the rotating wheel is fixedly connected with the sliding connecting rod and is in contact with the cam, the sliding connecting rod is hinged with the elastic hinged block and is connected withthe base in a sliding manner, the mixing tank is hinged with the hinged block and is fixedly connected with the elastic hinged block. The spiral ribbon-free vibrating pharmaceutical powder mixing device has a simple and reasonable structure; with a vibrating rolling type mixing way, the mixing speed and the mixing efficiency are both enhanced; by abandoning a conventional spiral ribbon stirring structure, pharmaceutical powder can be cleaner.

Description

technical field [0001] The invention relates to the field of pharmaceutical production equipment, in particular to a screwless belt vibration pharmaceutical powder mixing device. Background technique [0002] In the field of pharmaceuticals, the operation process of dispersing two or more solid powders of two or more components in a mixing equipment to achieve a uniform state is called mixing. The purpose of mixing is to disperse the drug powder and auxiliary material powder evenly. , to achieve the state of "random and complete mixing", which is convenient for subsequent preparation production, so that the content of the preparation is uniform, and the quality of the tablets is ensured. There will be a stirring ribbon, and the stirring ribbon is located in the mixing tank, and the stirring ribbon is installed on the rotating shaft. In order to reduce the mechanical wear of the bearing on the rotating shaft and the mixing tank, it is generally necessary to lubricate the bear...
