Description

Technical Field

[0001] The invention relates to the field of analytical instrument accessories, in particular to a portable infrared spectrum tablet pressing mold clamp device. Background Art

[0002] Infrared spectroscopy analysis requires that the particles of the object to be tested be pressed into transparent discs so that they can pass infrared light and be detected. When pressing the tablets, the force used varies from person to person. Too much force will cause the discs to stick to the mold and be difficult to remove, while too little force will cause uneven tablet pressing, affecting the accuracy of subsequent tests. In addition, the existing tablet presses used in infrared spectroscopy analysis require manual pressure to be pressed to a certain pressure and then left for several minutes to form, which makes the tablet pressing efficiency extremely low. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a portable infrared spectrum tablet pressing mold clamp device.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a method includes a lower pressing plate and an upper pressing plate whose rear end can be rotatably arranged on the lower pressing plate; the front end of the lower pressing plate is provided with a locking mechanism for locking the front end of the lower pressing plate with the front end of the upper pressing plate; it also includes a tightening mechanism for tightening the sample, the tightening mechanism includes a rotating rod arranged on the upper pressing plate and a base arranged on the lower pressing plate; the tightening mechanism also includes a heating wire arranged under the base.

[0005] The beneficial effects of the present invention are: the locking mechanism that locks the front end of the upper pressing plate and the tightening mechanism used to compress the sample ensure that when the tightening mechanism is tightened downward to compress the sample, the locking mechanism can ensure that the upper and lower pressing plates are relatively fixed, so that the rotating rod moves downward to compress the sample. At the same time, the heating wire at the bottom can soften the sample or meet the dehumidification requirements, thereby realizing the function of making a pressed sheet.

[0006] Further: the locking mechanism includes a flip bracket and a balance bracket; one end of the flip bracket is rotatably connected to the front end of the lower pressure plate, and the other end of the flip bracket is provided with a cross bar for limiting the angle between the upper pressure plate and the lower pressure plate; one end of the balance bracket can be rotatably arranged on the flip bracket.

[0007] The beneficial effects of the above further scheme are: the flip bracket is flipped to fasten the upper pressure plate, thereby ensuring that the angle between the upper and lower pressure plates is fixed, which is convenient for tightening the tightening mechanism; at the same time, the balance bracket is arranged at the bottom to ensure heat insulation from the tabletop during heating.

[0008] Further: the front end of the upper pressing plate is provided with a groove matching the cross bar.

[0009] The beneficial effect of the above further solution is that the groove provided at the front end of the upper pressing plate can ensure that the cross bar of the flip bracket is clamped in the groove, thereby ensuring that the flip bracket will not fall off from the upper pressing plate, thereby ensuring the reliability of the device.

[0010] Further: it also includes an upper blade and a lower blade constituting a scissors mechanism; the lower blade is arranged at the rear end of the lower pressing plate, and the upper blade is arranged at the rear end of the upper pressing plate and close to the lower blade.

[0011] The beneficial effect of the above further solution is that the sample can be cut conveniently by the provided scissor mechanism without the need for additional shearing tools, thereby greatly improving the work efficiency of sample preparation.

[0012] Further: the lower pressing plate and / or the upper pressing plate are provided with a weight reducing groove.

[0013] The beneficial effect of the above further solution is that the device is light in weight and easy to operate and carry by providing the weight-reducing groove.

[0014] Further: The swivel rod and base are made of high carbon steel.

[0015] The beneficial effect of the above further solution is that the use of high-carbon steel ensures that the pressing part has strong compression resistance and ensures that the device is more durable.

[0016] Further: the rotary rod is connected to the upper pressing plate through a thread, and a lever is provided at the upper end of the rotary rod.

[0017] The beneficial effect of the above further solution is that the lever ensures that the screwing is easier and more labor-saving.

[0018] Further: a spring pad is arranged on the connecting bolt between the tilting bracket and the balancing bracket.

[0019] The beneficial effect of the above further solution is that the spring pad can ensure that the connection between the flip bracket and the balance bracket is more firm and not easy to loosen.

[0020] Further: also includes a humidity sensor for detecting the humidity of the sample.

[0021] The beneficial effect of the above further scheme is: according to the "humidity" information that can be provided by the humidity sensor, the heating time is appropriately controlled to remove more water vapor from the test sample and the auxiliary sample, or to save energy consumption and shorten the test time.
