Embodiment 2

[0066] In the dry granulator of this embodiment, on the basis of the first embodiment, the feeding mechanism described in the first embodiment is further limited. Such as Figure 5 , Figure 6 and Figure 7 As shown, the feeding mechanism also includes a housing structure 12. The housing structure 12 includes a flat material part and a mounting part. A feeding channel is formed between the flat material part and the material receiving part 2. A storage bin for storing materials. Preferably, the edge line of the flat material part is parallel to the material receiving plate 14, so that the material passing through the feeding channel is evenly laid on the material receiving part 2. It should be noted that the structure of the flat material part can be set according to actual needs.

[0067] Specifically, the accommodating structure 12 in this embodiment is a U-shaped structure in a top view, and the feeding structure 13 is connected to the accommodating structure 12 to block...

Embodiment 3

[0079] The dry granulator of this embodiment further defines the rolling mechanism described in the first embodiment on the basis of the first embodiment.

[0080] Among them, such as Figure 8-Figure 11 As shown, the telescopic assembly includes a first hinge 29, a second hinge 30 and a third drive 31, the first hinge 29 is hinged with the first pressure roller 3, and the second hinge 30 is hinged with the second pressure roller 4; The first hinged part 29 and the second hinged part 30 are respectively connected with a third driving part 31 , and the third driving part 31 is adapted to drive the first hinged part 29 and the second hinged part 30 to move toward each other. Specifically, the third driving member 31 is disposed between the first hinge member 29 and the second hinge member 30 .

[0081] Since the first hinged part 29, the second hinged part 30 and the press roller are hingedly connected, the processing accuracy and assembly accuracy of the telescopic assembly will...

Abstract

The invention relates to the technical field of particle preparation, in particular to a dry type granulator. A rolling mechanism comprises a first driving part and a rolling assembly connected with the first driving part; the rolling assembly comprises a first compression roller, a second compression roller and a telescopic assembly, the first compression roller is arranged above the second compression roller, and the first end of the first pressing roller is hinged to the first end of the second pressing roller. The telescopic assembly is connected with the second end of the first pressing roller and the second end of the second pressing roller. The granulating mechanism comprises a second driving part and a granulating assembly connected with the second driving part, wherein the second driving part is suitable for driving the granulating assembly to act; the rolling assembly and the granulating assembly are arranged in the box body, and the first driving piece and the second driving piece are arranged outside the box body; the feeding mechanism is connected with the rolling mechanism so as to feed materials to the position between the first pressing roller and the second pressing roller. The dry type granulator is compact in structure and can be operated by a single person, the structural design better conforms to human engineering, and the granulation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of particle preparation, in particular to a dry granulator. Background technique [0002] In the pharmaceutical industry, it is widely involved in the processing of various active pharmaceutical raw materials and one or more excipients. Most of these raw materials are fine powders with different particle sizes, uneven density, poor fluidity, and easy layering. These raw materials must be processed through a granulation process. The existing dry granulation system mainly includes a rolling device and a granulation device, wherein the material is pressed into a sheet or strip by the rolling device, and then the sheet or strip is cut into granules by the granulation device shape. Contents of the invention [0003] Therefore, the present invention provides a dry granulator. [0004] Technical scheme of the present invention is: [0005] A dry granulator, comprising a rolling mechanism, a granulation mecha...
