Description

Technical Field

[0001] The invention relates to the technical field of coal quality detection, and in particular to a cup-shaped body holding and wrapping sample mechanism. Background Art

[0002] Carbon and hydrogen are the main components of coal organic matter, and together with oxygen, they account for more than 95% of coal organic matter; and nitrogen is the only element in coal that exists completely in organic form. Therefore, understanding the carbon, hydrogen and nitrogen content in coal is of great significance for understanding the properties of coal, checking the test results of other indicators, and estimating indicators such as heat, materials, and pollutant emissions during the coal application process.

[0003] The experimental samples of carbon, hydrogen and nitrogen element analyzers in the coal quality testing instrument industry on the market are in powder form. In order to ensure that the sample analysis results are accurate and effective, ultra-thin (thickness of about 0.02mm) tin foil cups are usually required to hold and wrap the test samples. When wrapping, all the air inside the samples and tin foil cups needs to be exhausted. How to realize a stable, reliable, efficient, high-qualified and low-cost tin foil cup automatic sample packaging mechanism is an urgent problem to be solved in this field. The automatic sample packaging mechanism of the current existing technology is complex, with high processing precision, poor operating stability and high cost. Summary of the invention

[0027] The following will combine with the drawings to describe in detail the preferred embodiments of the present invention and further elaborate on the present invention.

[0028] First, it will be combined with Figures 1 - 2A cup-shaped body holding and packaging sample mechanism according to an embodiment of the present invention is described, which is used to hold and package the cup-shaped body (i.e., tinfoil cup) containing the sample of the element analyzer, and wrap the cup-shaped body containing the sample into a water drop shape, which has a wide range of application scenarios.

[0029] like Figures 1 - 2 As shown, the cup-shaped sample-holding and packaging mechanism of the embodiment of the present invention comprises a bracket 1, a conveying module and a wrapping module.

[0030] Specifically, Figures 1 - 2 As shown, the conveying module is connected to the bracket 1 and is used to convey the cup-shaped body containing the sample. The conveying module includes: a pressing sleeve 21, an elastic tube 22 and a through hole 23. The pressing sleeve 21 is arranged at the top of the bracket 1. The pressing sleeve 21 is a hollow structure, which is used to provide space for the cup-shaped body containing the sample to enter the elastic tube 22; the top of the elastic tube 22 is connected to the top of the pressing sleeve 21 and the wrapping module, and the elastic tube 22 is connected to the pressing sleeve 21. The elastic tube 22 can be a rubber elastic tube 22, a silicone elastic tube 22 or a mesh elastic tube 22. The pressing sleeve 21 can open the top of the elastic tube 22 to be enough to hold the cup-shaped body containing the sample into the elastic tube 22; the through hole 23 is opened at the bottom of the bracket 1, and the through hole 23 is connected to the bottom of the elastic tube 22, which is used to convey the water drop-shaped package sample after the wrapping treatment.

[0031] Further, if Figures 1 - 2 As shown, the conveying module includes: a guide sleeve 24, which is inserted into the through hole 23, and the guide sleeve 24 is a hollow structure. The top of the guide sleeve 24 is connected to the bottom of the elastic tube 22, and is used to guide the discharge of the drop-shaped package body after the packaging process.

[0032] Further, if Figures 1 - 2 As shown, the axial center lines of the guide sleeve 24, the elastic tube 22 and the pressing sleeve 21 are on the same straight line, ensuring the smoothness of the entire sample wrapping process and the balance during sample wrapping.

[0033] Specifically, Figures 1 - 2As shown in the figure, the wrapping module is connected to the bracket 1 and the conveying module, and is used to wrap the cup-shaped body containing the sample conveyed by the conveying module into a water droplet shape. The wrapping module includes: a slider 31 and an elastic locking ring 32. The slider 31 is arranged on the bracket 1 in a liftable manner. One end of the slider 31 is provided with a guiding port 311, and the guiding port 311 is sleeved on the elastic tube 22. Inside one end of the slider 31, there is a placement cavity 312, and the placement cavity 312 is communicated with the guiding port 311. The slider 31 can be connected to an external driving mechanism (such as a linear mechanism like an electric cylinder or a cylinder), and the slider 31 is driven by the external driving mechanism to move up and down on the bracket 1; the elastic locking ring 32 is arranged in the placement cavity 312, the elastic locking ring 32 is sleeved on the elastic tube 22, and the elastic locking ring 32 follows the slider 31 to slide up and down along the axial direction of the elastic tube 22. The elastic locking ring 32 is a rubber ring or a spring ring. The elastic deformation of the elastic locking ring 32 and the elastic tube 22 is used to complete the wrapping of the foil cup containing the sample. The wrapping force is evenly distributed in the circumferential direction and automatically adjusts the wrapping space according to the shape of the object to be wrapped.

[0034] Further, as Figures 1 - 2 shown, the outer diameter a of the elastic locking ring 32 is smaller than the diameter b of the placement cavity 312, which can provide a certain expansion space for the elastic locking ring 32 by the placement cavity 312.

[0035] Further, as Figures 1 - 2 shown, the outer diameter a of the elastic locking ring 32 is larger than the diameter c of the guiding port 311, preventing the elastic locking ring 32 from disengaging from the guiding port 311.

[0036] Further, as Figures 1 - 2 shown, the thickness of the elastic locking ring 32 is equal to or greater than the height of the placement cavity 312, ensuring that the elastic locking ring 32 can follow the slider 31 to slide up and down along the axial direction of the elastic tube 22.

[0037] During operation, the slider 31 is driven by an external driving mechanism to move on the bracket 1. The slider 31 drives the elastic locking ring 32 to move to the lower end of the elastic tube 22. The cup-shaped body containing the sample enters the elastic tube 22 through the hollow structure of the pressing sleeve 21; then the slider 31 is controlled to move upward, driving the elastic locking ring 32 to move upward. Through the elastic deformation of the elastic tube 22 and the elastic locking ring 32, the cup-shaped body containing the sample is tightly wrapped into a water droplet-shaped wrapped sample body; the slider 31 continues to move upward, the elastic tube 22 loosens, and the water droplet-shaped wrapped sample body disengages from the tightly clamped position of the elastic locking ring 32 and falls to the guiding sleeve 24 under the action of gravity and is discharged through the hollow structure of the guiding sleeve 24, completing the entire wrapped sample process.

[0038] As Figures 1 - 2 shown, for the cup-shaped body clamping and wrapping mechanism according to the embodiment of the present invention, the structure of the present invention is compact and simple, the cost is low, the wrapping effect is better, and there is no need to adjust to adapt to the wrapping of samples of different sizes.
