Description

Automatic winding device for multilayer quantitative ring

Technical Field

The utility model belongs to ration ring winding field, concretely relates to an automatic coiling device for multilayer ration ring.

Background

At present, the domestic gas chromatograph is developed rapidly and gradually begins to compete with various domestic gas chromatographs with large imported gas chromatographs. For products such as gas chromatography, which are integrated mechanically and electronically and have tightly combined software and hardware, part standardization and automatic processing are realized, and generalization is more and more necessary for reducing the cost of the whole instrument.

The gas chromatograph aims at realizing automation of indirect sample injection analysis of gas samples or liquid samples, and the most common method is to adopt a switching valve for direct sample injection or a thermal analysis instrument and a headspace sample injector switching valve for sample injection in imported or domestic chromatographic instruments. Using a valve to control the gas sample introduction, a suitable volume of the dosing ring must be used. Generally, gas chromatographic analysis has different concentrations, different detectors and different column capacities according to different sample component contents, and most of the volumes of the quantitative rings are between 0.05mL and 5 mL.

The quantitative ring is generally limited by factors such as the size specification of a connector of the switching valve, dead volume and the like, and is generally limited by the strength of a pipeline because a large number of 1/16-inch outer diameter pipes with small diameters are adopted, the wall thickness of the pipe cannot be too thin, and the inner diameter is usually 1 mm. For a part of large-volume sample injection quantitative rings, a small amount of instruments are manufactured by adopting a metric tube with the outer diameter of 3mm and the inner diameter of 2 mm. For the most common chromatographic quantitative ring manufacture with small volume of 0.XmL, the stainless steel tube with the outer diameter of 1/16 inches made by English is short in winding length, and can be directly and manually wound into a ring shape. For the large-volume quantitative ring, the volume is usually 1-5 mL, and the required pipeline length is more than 1 m. If the quantitative ring is used in the valve box, the quantitative ring is manually wound into a spring shape with a certain appearance size so as to be convenient to install. The manual winding must be mastered with certain skills, and particularly, the quantitative rings requiring multi-layer winding are difficult to wind manually under the condition that the spring-shaped height and diameter have certain limits. The quantitative ring parts have certain differences in appearance, the diameters and the heights are difficult to be consistent, and loosening is often caused, so that batch and standardized manufacturing of the quantitative ring parts is influenced to a certain extent. For this reason, there is a need for a quantitative hoop winding manufacturing tool that can be very easily standardized.
