Description

Technical Field

[0001] The invention relates to the pharmaceutical field, and in particular to a medicine pretreatment crushing and grinding device for medicine granulation. Background Art

[0002] Drug granulation is the process of making drug powder into granules. In the pharmaceutical industry, many drug raw materials exist in the form of powders, which have problems such as poor fluidity, easy to fly, and difficult to mix evenly. Granulation can improve the fluidity of drugs and make them easier to handle in subsequent production processes (such as tableting, capsule filling, etc.).

[0003] In order to better granulate the pharmaceutical raw materials, various pharmaceutical raw materials need to be ground and crushed first. Currently, most of the drug grinding is done by hand grinding machines, which have low grinding efficiency and low grinding quality. Mechanical grinding is difficult to control the size of the grinding particles. Often the grinding accuracy of a single machine cannot be adjusted, which is not convenient for flexible adjustment according to the actual situation of the drug, and is relatively inconvenient in actual use.

[0004] For this reason, it is necessary to invent a medicine pretreatment pulverizing and grinding device for medicine granulation. Summary of the invention

[0005] To this end, the present invention provides a medicine pretreatment pulverizing and grinding device for medicine granulation to solve the problems in the background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a drug pretreatment pulverizing and grinding device for drug granulation, comprising a casing, a grinding block and a grinding seat are arranged inside the casing, the grinding block is located at the top of the grinding seat and is movably connected to the casing, the grinding seat is slidably connected to the casing, and an adjusting component that can control the grinding seat to move up and down is arranged at the bottom of the grinding seat, the top of the grinding block is fixedly connected to a vertical shaft, the top of the vertical shaft extends to the top of the casing and is fixedly connected to a bevel gear 1, the top of the casing is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a bevel gear 2, the bevel gear 2 is located on one side of the bevel gear 1 and is meshed with the bevel gear 1, a plurality of blocks are fixedly connected to the inner wall of the top of the casing, a plurality of extrusion components are arranged inside the grinding block, a plurality of feed holes are arranged on the top of the grinding block, a track groove is opened at the top of the casing, and a feed hopper is slidably embedded in the track groove.

[0007] Preferably, the extrusion assembly includes a column slidably embedded in the grinding block, the bottom end of the column is fixedly connected to a pressure plate, the top of the column is fixedly connected to a pressure block, the top of the pressure block is provided with an inclined surface, and the pressure block is fixedly connected to one side close to the grinding block with two springs, the two springs are respectively located on both sides of the column, and the bottom end of the spring is fixedly connected to the surface of the grinding block.

[0008] Preferably, a limiting column is sleeved inside the spring, the top of the limiting column is fixedly connected to the pressing block, and the bottom end of the limiting column extends into the interior of the grinding block and is slidably connected to the grinding block.

[0009] Preferably, the adjustment assembly includes a base fixedly mounted on the bottom inner wall of the casing, an air cavity is opened inside the base, a piston rod 1 is embedded in one end of the air cavity, the top end of the piston rod 1 extends to the outside of the base and is fixedly connected to the bottom of the grinding seat, a piston rod 2 is embedded in the other end of the air cavity, a screw is embedded in the piston rod 2, one end of the screw extends to the outside of the casing and is fixedly connected to a knob, and the screw is threadedly connected to the piston rod 2.

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention arranges a grinding block, a grinding seat, an adjustment component and a plurality of extrusion components in the grinding block inside the housing. In actual use, the motor drives the grinding block to rotate, and the top of the pressing block will contact the bottom surface of the clamping block in stages. Due to the inclined surface at the top of the pressing block, the pressing block will be squeezed and shrink downward when in contact, so that the column slides down inside the grinding block, thereby driving the pressing plate to press down.
