Internal dispersion chemical and pharmaceutical granulation machine

Abstract

The invention discloses an internal dispersion chemical and pharmaceutical granulation machine. The internal dispersion chemical and pharmaceutical granulation machine comprises a smashing barrel, a feeding device, a driving gear, a driven gear, a smashing roller, a dispersion disc, a rotating shaft, a driving motor, a guide plate, a screen, a vibration motor, a spring, a discharging groove, a discharging pipe and a supporting frame; the feeding device is connected to the top end of the smashing barrel; one cover plate is connected with a limiting piece installed on the shell through a handle, a first flange is arranged at a feeding opening, a second flange is installed at a discharging opening, and a first insertion plate and a second insertion plate are arranged on the outer side of the first flange and the outer side of the second flange correspondingly; the driving gear and the driven gear are arranged on the upper side of the interior of the smashing barrel side by side, are symmetrically arranged, and are in meshed connection; the smashing roller is arranged on the middle section of the interior of the smashing barrel; and in the using process, fed materials can be effectively and evenly scattered through the feeding device, the circulation effect is improved, and the using effect is good.

Description

technical field [0001] The invention relates to the field of pharmaceutical machinery, in particular to an internally dispersed chemical and pharmaceutical granule machine. Background technique [0002] Drug pulverization is the operation process of crushing large solid substances into appropriate fineness by means of mechanical force. The main purposes of pulverization are: (1) to increase the surface area of ​​the drug and promote the dissolution of the drug. (2) It is beneficial to the preparation of various pharmaceutical dosage forms. (3) Accelerate the dissolution of active ingredients in medicinal materials. (4) It is convenient to deploy, take and bring into play the medicinal effect. (5) It is convenient for drying and storage of fresh medicinal materials. [0003] The difficulty of drug crushing mainly depends on the structure and properties of the substance, but it is also closely related to the magnitude of the external force. Various crushing machines act o...

AI Technical Summary

Problems solved by technology

[0004] Traditional Chinese medicine often needs to crush medicines. There are two general crushing methods, one is manual grinding and crushing, and the other is crushing with a pulverizer. Manual grinding and crushing is not only labor-intensive, but also low in efficiency, so it is not suitable for large-scale crushing Work, the existing pulverizers generally have the disadvantages of high noise, difficult feeding control, easy clogging, poor pulverization effect, insufficient pulverization, and inconvenient movement, and cannot screen drugs and cannot meet the needs of use; urgent improvement is needed
