Abstract

The invention discloses an automatic grinding and tabletting press. The automatic grinding and tabletting press comprises a grinding device, a sieving device and a tabletting device in sequence from top to bottom, wherein the grinding device comprises more than two layers of grinding layers which are stacked, and each grinding layer comprises more than two pairs of grinding columns which are horizontally arranged; the sieving device comprises a stainless steel screen mesh and a patch type vibrator arranged on the stainless steel screen mesh; the tabletting device comprises a tabletting room, an upper pressing pate, an upper pressing plate driving motor, an air cylinder and an air pump; the air pump is connected with the air cylinder, a piston of the air cylinder is upward and vertically arranged, and the piston of the air cylinder is arranged in the tabletting room in a sliding way; and a sample feeding hole is formed in the top of the tabletting room. According to the automatic grinding and tabletting press, the efficiency of sample grinding and tabletting is greatly improved, and the consistency of sample processing is improved.

Description

technical field [0001] The invention relates to the field of laboratory testing equipment, in particular to an automatic grinding tablet press for making infrared samples. Background technique [0002] Infrared spectroscopy is a commonly used detection method for material structure. For solid detection samples, it is generally mixed with potassium bromide, ground to a fine powder, and then pressed into tablets during sample preparation. In the prior art, for the grinding and tableting steps of solid sample preparation, it is generally manual, ground in an agate mortar, passed through a 200-mesh sieve (or observe the degree of grinding of the sample with the naked eye), and then transfer to Tablets were compressed manually in a tablet press. The method of manual sample preparation is time-consuming, inefficient, and the sample consistency deviation is large, which has a negative impact on the experimental results. Contents of the invention [0003] In order to solve the ...
