Description

Technical Field

[0001] This utility model relates to the field of powder tableting, and specifically to a continuous powder tableting device. Background Technology

[0002] A powder compaction device is a specialized instrument used to compress loose powder samples into solid, uniform tablets under specific pressure. Its core working principle involves using hydraulic or mechanical drive to apply high pressure to the powder in a mold, overcoming the voids and resistance between powder particles, causing plastic deformation and mechanical engagement, thereby forming a sample tablet with a specific shape, mechanical strength, and density. This device is widely used in sample pretreatment processes for elemental analysis techniques such as X-ray fluorescence spectroscopy. The prepared sample tablets have smooth surfaces and uniform composition, effectively eliminating particle size and mineral effects in powder samples, greatly improving the accuracy and reliability of analytical results, making it an indispensable sample preparation tool in the laboratory.

[0003] Chinese patent CN221540764U discloses a solid powder sample tableting device, belonging to the field of tableting devices. It includes a powder tableting machine, a worktable, and a tableting mold. By installing a positioning mechanism on the worktable, the tableting mold is placed on the top surface of the positioning table. Manually rotating a knob drives a bidirectional adjusting threaded rod, causing two adjusting blocks to move relative to each other through threaded holes on the side walls along the bidirectional adjusting threaded rod in a transverse opening. This causes the arc-shaped clamping plates mounted on the L-shaped rod on the top surface to move synchronously, thereby positioning and fixing the tableting mold between the symmetrical arc-shaped clamping plates and placing it directly below the stamping screw. This achieves rapid positioning of the tableting mold without the need for repeated manual adjustments, saving time and effort. Furthermore, it ensures more uniform force distribution on the tableting mold during the stamping process, improving the tableting effect and efficiency of solid powder samples. However, this device still has the following problems: 1. After the device compresses the powder into tablets, the upper mold needs to be replaced before the tablets can be removed, which is a rather cumbersome process.

[0004] 2. When aligning the mold, the device requires manual adjustment of the positioning knob by turning the knob, which is quite time-consuming.
