Abstract

The invention relates to a grinding tableting machine. A cutter blade and a first power element are arranged in a crushing chamber; the cutter blade is rotationally connected onto the output end of the first power element; the sieving part comprises a filter screen; the filter screen is transversely arranged in a casing and is connected with the inner wall of the casing; a second power element, areverse conical collection hopper and a tableting cabin are arranged in the tableting chamber; a feeding opening is formed above the tableting cabin; an upper end opening of the reverse conical collection hopper is arranged under the filter screen; a lower end opening of the reverse conical collection hopper is formed in the feeding opening position of the tableting cabin; the output end positionof the second power element corresponds to the feeding opening position of the tableting cabin; the second power element is used for tightly pressing the powder into the tableting chamber; The grinding tableting machine has the advantages of high grinding efficiency and efficient tablet making. The uncertain factor influence of manual operation is reduced; the experiment accuracy is greatly improved.

Description

technical field [0001] The invention relates to the field of sample grinding, in particular to a grinding tablet pressing machine. Background technique [0002] Infrared spectroscopy is widely used to identify compounds and determine molecular structures. It can perform qualitative and quantitative analysis of substances. It has the characteristics of strong characteristics and high sensitivity. It is a commonly used detection method for substance structures. [0003] When detecting solid samples by infrared spectroscopy, the solid samples must first be ground and pressed into tablets. In the prior art, the solid samples are put into an agate mortar for grinding, and then the ground fixed samples are put into a tablet press for pressing. Tablets, agate mortar grinding samples and tablet press tableting are both done manually, so the particle size deviation of sample grinding is relatively large, and it takes a long time and is inefficient, resulting in large experimental err...
