High-speed rotary type automatic injection device for liquid sample

Abstract

The invention discloses a high-speed rotary type automatic injection device for a liquid sample. The high-speed rotary type automatic injection device comprises a base plate, a rack, a two-dimensional mobile platform arranged on the rack, a sample injection assembly, a sample injection table, a sample bottle and a waste liquid bottle, wherein the two-dimensional mobile platform comprises a horizontal sliding rail assembly driven by a motor and a vertical sliding rail assembly driven by the motor; the sample injection assembly comprises a sample injection needle and a sample injection needle fixing seat; the sample injection needle fixing seat is arranged on the two-dimensional mobile platform; a piston rod of the sample injection needle is connected with a power source; the sample injection table comprises a rotary sample table driven by the motor and a sample filling tube. The device can be used for uniformly adding the liquid sample into a soft matter; in addition, when a sample solution is injected into the sample filling tube by using the sample injection needle, the problems of unsteady motion, jitter, injection failure and the like are solved by rotating the sample injection table at high speed. Meanwhile, a circuit control system is added on the device, so that automation of injection is realized, and the problems of lower accuracy, stability and working efficiency of manual injection and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of liquid sample filling, in particular to a high-speed rotary liquid sample automatic injection device, which can be used for filling liquid spices into cigarettes and other articles, so as to carry out relevant smoking evaluation and research tests. Background technique [0002] With the improvement of people's quality of life, consumers' preferences and demands for fragrance are increasing day by day. Various public places and private residences create pleasant fragrances, which can make people feel happy in the senses and eliminate fatigue and other needs. Fragrance solutions may need to be infused into gels, powders, filaments, etc., for long-lasting fragrance. [0003] With the continuous development of automation technology, automatic sampling and injection of liquids has developed rapidly. The combination of three-dimensional platform and injection needle has been applied in the fields of automatic ...

AI Technical Summary

Problems solved by technology

[0004] At present, when manually injecting flavor solution into samples with a hardness greater than liquid, such as cigarettes, the sample injection is uneven and time-consuming, which is not conducive to repeated analysis and large-scale sample preparation.
