Raw material block crushing device

Abstract

The invention discloses a raw material block crushing device. The raw material block crushing device comprises a main hydraulic cylinder, a hollow crushing box, a crushing device, a transmission device and an ejecting device; two material outlets are formed in the side wall of the hollow crushing box; the crushing device comprises a rotating motor, an upper hollow crushing disc and a lower crushing plate; the transmission device comprises an inverted U-shaped rod, a U-shaped hinging rod, a transmission straight rod and a T-shaped pushing rod; the rotating motor is fixedly arranged on the inverted U-shaped rod; the upper end of the T-shaped pushing rod penetrates through a through hole; a circular plate pushing block is arranged at the upper end of the T-shaped pushing rod; a first rotatingshaft is arranged in the U-shaped hinging rod; symmetric U-shaped hinging seats are arranged at the two ends of the bottom of the T-shaped pushing rod; second rotating shafts are arranged in the U-shaped hinging seats; the ejecting device comprises a sub hydraulic cylinder; and a material pushing plate is arranged at the tail end of a telescopic rod of the sub hydraulic cylinder. According to theraw material block crushing device, the structure is simple, raw material blocks can be initially crushed, block-shaped raw materials are changed into powders, and the powder mixing difficulty in thelater period can be reduced.

Description

technical field [0001] The invention belongs to the technical field of tablet processing equipment, in particular, the invention relates to a raw material block crushing device. Background technique [0002] APIs are the material basis for drug production, and the finished or semi-finished products of these APIs must be processed into powders suitable for taking before they become medicines. In the pharmaceutical process, it is often necessary to mix, stir, and grind a large amount of agglomerated medicines to prepare medicine powders. In the prior art, the bulk medicines are mostly directly transported into the reaction kettle without pretreatment, and are directly mixed, stirred and ground in the reaction kettle, resulting in that the block materials cannot be effectively broken and pulverized after being stirred for a long time, which affects the pharmaceutical efficiency. . SUMMARY OF THE INVENTION [0003] The invention provides a raw material block pulverizing devi...
