Description
Technical Field
[0001] The utility model relates to the technical field of spectrometer sampling, in particular to an automatic sampler for a spectrometer. Background Art
[0002] A spectrometer, also known as a spectrometer, is a device that uses light detectors such as photomultiplier tubes to measure the intensity of spectral lines at different wavelengths. It uses the capture of light information to develop photographic film or use computerized automatic numerical instruments to display and analyze, thereby detecting what elements are contained in an object.
[0003] Currently, before detecting powdered objects, operators are required to use a sampler to pressurize the powdered objects into a thin sheet shape. However, during the sample preparation process, due to the different internal stresses and tensions of the powdered objects, the sampler may cause cracks and corner defects in the shaping of the powdered objects.
[0004] According to the above, how to solve the problem of the integrity of the tableting of powdered articles under normal conditions is the technical difficulty that the present invention needs to solve. Utility Model Content
[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.
[0006] To this end, the technical solution adopted in this utility model is:
[0007] An automatic sampler for a spectrometer comprises a material loading mechanism and a powder clamping mechanism, wherein the material loading mechanism comprises a reinforced vertical cylinder with a recessed hole built therein, a base located directly below the reinforced vertical cylinder, a positioning clamping ring movably mounted on the top of the reinforced vertical cylinder, a booster rod penetrating into the interior of the reinforced vertical cylinder, a top seat mounted on the top of the booster rod, a beam rod welded to the edge of the bottom surface of the top seat, and a cushion block placed inside the reinforced vertical cylinder; the powder clamping mechanism installed in the material loading mechanism comprises a vertical shaft movably mounted at the center of the top surface of the reinforced vertical cylinder, a base movably mounted on the top of the vertical shaft, a limit slip ring movably mounted inside the reinforced vertical cylinder, two guide sliders mounted outside the limit slip ring, a push rod mounted inside the limit slip ring, and a spring connected to the bottom end of the push rod.
[0008] In a preferred example, the utility model can be further configured as follows: the top of the reinforcing vertical cylinder is also provided with vertical holes distributed in a ring shape, and the inner diameter length of the vertical holes at the top of the reinforcing vertical cylinder is the same as the inner diameter length of the cushion block.
[0009] By adopting the above technical solution, a concave hole adapted to the top of the push rod is opened at the bottom of the inner cavity of the vertical hole at the top of the reinforced vertical cylinder. When the cushion block is pressurized by the booster rod, the top of the push rod pushes the bottom of the cushion block upward, thereby facilitating the quick removal of the cushion block.
[0010] In a preferred example, the utility model can be further configured as follows: four holes adapted to the beams are opened at the edge of the top of the reinforced vertical tube, and the four holes at the top of the reinforced vertical tube are located outside the vertical hole.
[0011] By adopting the above technical solution, the four holes opened inside the reinforced vertical tube are used to limit the beam rod, and the length of the holes in the reinforced vertical tube is set to twice the length of the beam rod, so that the top seat and the booster rod can be stably pressurized.
[0012] In a preferred example, the utility model can be further configured as follows: the top and bottom ends of the inner side of the positioning clamp ring are respectively provided with outwardly protruding T-shaped ring buckles, and the T-shaped ring buckles at both ends of the inner side of the positioning clamp ring are respectively adapted to the sliding groove outside the base and the ring groove outside the top end of the reinforcing vertical tube.
[0013] By adopting the above technical solution, the base is tightly constrained to the top of the reinforced vertical cylinder by using a positioning clamp ring. When the base rotates, it is subject to the dual constraints of the vertical axis and the positioning clamp ring, which can ensure the safe use of the base and prevent powder from falling onto the workbench.
[0014] In a preferred example, the utility model can be further configured as follows: the booster rod is made of solid stainless steel metal.
[0015] By adopting the above technical solution, the booster rod is made of solid stainless steel, which can ensure the strength of the booster rod when it is under pressure.
[0016] In a preferred example, the utility model can be further configured as follows: a hexagonal protruding end is provided on the outside of the base, and a cylindrical hole groove is provided inside the hexagonal protruding end that is symmetrically adapted to the vertical hole at the top of the reinforced vertical cylinder.
[0017] By adopting the above technical solution, the external hexagonal end of the base is used to fit and rotate with the vertical hole on the top of the reinforced vertical cylinder. When the powder is introduced into the vertical hole on the top of the reinforced vertical cylinder and spread on the pad, the powder is scraped off by the external hexagonal end of the base, thereby achieving rapid combing and flattening of the powder.
[0018] In a preferred example, the utility model can be further configured as follows: annularly distributed notches are provided inside the limiting slip ring, and the annularly distributed notches inside the limiting slip ring are respectively adapted to a plurality of ejector rods.
[0019] By adopting the above technical solution, multiple push rods are constrained as a whole, so that the multiple push rods can clamp multiple groups of cushion blocks and exert balanced upward thrust to ensure the integrity of the tableting powder on the top of the cushion block.
[0020] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0021] 1. In the utility model, a reinforcing vertical cylinder with multiple vertical holes on the top is provided, and through holes distributed in an annular shape are provided on the outside of the reinforcing vertical cylinder. The through holes on the outside of the reinforcing vertical cylinder are connected with the vertical holes on its top. At the same time, the booster rod is combined with the continuous pressurization of the powder on the top of the cushion block in the vertical hole on the top of the reinforcing vertical cylinder under the pressure of the oil pressure equipment. After shaping, the cushion block is pushed upward by the guide slider and the push rod, so that the powder spread on the top of the cushion block can be safely withdrawn after being pressed into tablets.
[0022] 2. In the utility model, a guide slider and a push rod are movably installed inside the reinforced vertical cylinder, and a spring is connected to the bottom end of the push rod. When the oil pressure equipment vertically pressurizes the top seat, the air pressure in the inner cavity of the vertical hole on the top of the reinforced vertical cylinder is adjusted by the external through hole of the reinforced vertical cylinder, so that the powder spread on the top surface of the cushion block can be evenly pressurized, and the problem of difficulty in withdrawing the cushion block due to excessive pressure can be avoided.
