Abstract
Description
Technical Field
[0001] This utility model relates to the field of tableting equipment technology, and in particular to a tableting device for infrared spectroscopy. Background Technology
[0002] When measuring the absorption characteristics of a substance in the infrared band, the substance usually needs to be prepared into a transparent and uniform thin film to ensure that infrared light can penetrate the sample and obtain an accurate spectrum. The main function of the pellet pressing device in infrared spectrometer is to convert the solid sample into a thin film form to meet the sample interface and optical path requirements of the infrared spectrometer.
[0003] For example, the announcement number CN219715217U describes a tablet pressing device for an infrared spectrometer. This device solves the problem that current infrared spectrometer tablet pressing devices are cumbersome to remove after pressing, requiring a long time and affecting work efficiency. It includes a base, a support frame connected to one side of the upper end of the base, a lead screw connected to the middle of the upper end of the support frame, a pressure plate connected to the lower end of the lead screw, a placement plate connected to the upper end of the base, and a discharge component connected to the upper end of the placement plate. This invention, through the setting of the discharge component, rotates the pull plate to one side, causing the pull rod to no longer be in a fixed state. Under the elastic potential energy of the spring, it drives the moving plate upward, which in turn drives the support rod to move, and the support plate to move the circular plate. This causes the circular plate to move the material to the outside of the mold groove, thereby automatically discharging the material, reducing the time required for material removal, and improving the material discharge efficiency.
[0004] While common infrared spectroscopy tableting devices can convert solid samples into tablets, the tableting mold is usually fixed manually by the operator, which is inconvenient and prone to error, affecting the tableting effect. In addition, a small amount of powder is scattered on the workbench surface during demolding, requiring manual cleaning and increasing the workload of the operators. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0022] like Figures 1-5As shown, this embodiment provides a tableting device for infrared spectroscopy, including a tableting machine body 1. A mounting plate 2 is fixedly installed on the upper end of the tableting machine body 1. A lead screw 3 with a crank handle at one end is threadedly connected to the middle of one end of the mounting plate 2. A worktable 4 for placing the tableting mold is fixedly installed on the tableting machine body 1. Square grooves 5 are formed on both sides of the upper end of the worktable 4. A movable arc-shaped limiting plate 7 is installed in the square grooves 5 via a drive assembly 6. A cleaning assembly 8 for cleaning the worktable 4 is installed at one end of the mounting plate 2. One end of the cleaning assembly 8 is connected to the arc-shaped limiting plate 7. An integrated control panel 9 is fixedly installed at one end of the tableting machine body 1. An anti-slip pad 10, made of rubber, is fixedly installed at one end of plate 7. During operation, the tablet press body 1 retains its existing structure. First, the powder to be tableted is placed into the tableting mold. Then, the tableting mold is manually placed on the worktable 4. Next, the drive assembly 6 is manually activated via the integrated control panel 9, causing the arc-shaped limiting plate 7 to move in opposite directions, automatically positioning the tableting mold. This eliminates the need for manual positioning, making it convenient, quick, and improving the tableting effect. The anti-slip pad 10 at one end of the arc-shaped limiting plate 7 increases the friction between the arc-shaped limiting plate 7 and the tableting mold. Then, the crank handle is manually turned, causing the lead screw 3 to rotate and move downwards for tableting. Pressure is then applied through the tablet press body 1. After tableting, the tablet press body 1 releases pressure, and the lead screw 3 is reset. Demolding then occurs. After demolding, the cleaning assembly 8 is manually activated via the integrated control panel 9 to automatically clean the powder and other impurities adhering to the surface of the worktable 4, saving time and effort and reducing the burden on operators.
[0023] like Figure 3 and Figure 4 As shown, the drive assembly 6 includes a servo motor 601, a bidirectional lead screw 602, and a round rod 603.

The round rod 603 is fixedly installed in the square groove 5 on the other side. The other end of the arc-shaped limiting plate 7 is sleeved on the outside of the round rod 603. The servo motor 601 is fixedly installed on the outside of the worktable 4. The output end of the servo motor 601 is fixedly connected to the bidirectional lead screw 602. The servo motor 601 is electrically connected to the integrated control panel 9. In use, the servo motor 601 is first manually started through the integrated control panel 9, which drives the bidirectional lead screw 602 to rotate, causing the arc-shaped limiting plate 7 to move towards each other, thus automatically positioning the tablet pressing mold. The round rod 603 plays a guiding and limiting role. After the tablet pressing is completed, the servo motor 601 is started in reverse through the integrated control panel 9 to reset and move the arc-shaped limiting plate 7.
[0024] like Figure 5As shown, the cleaning component 8 includes a small vacuum cleaner 801 and a Y-shaped tube 802. The small vacuum cleaner 801 is fixedly installed on one side of the mounting plate 2. The Y-shaped tube 802 is connected to the output end of the small vacuum cleaner 801. The small vacuum cleaner 801 is electrically connected to the integrated control panel 9. A cavity 803 is opened inside the arc-shaped limiting plate 7. A suction hole 804 is opened on the lower side of one end of the arc-shaped limiting plate 7. One end of the suction hole 804 is connected to the cavity 803. A dust conveying tube is fixedly installed on one end of the Y-shaped tube 802. 805. One end of the dust conveying pipe 805 extends into the cavity 803. During use, after demolding, the small vacuum cleaner 801 is manually started through the integrated control panel 9. The powder and other impurities adhering to the surface of the workbench 4 are conveyed into the cavity 803 through the dust suction hole 804, and then conveyed into the Y-shaped pipe 802 through the dust conveying pipe 805. Finally, the impurities are conveyed into the small vacuum cleaner 801 through the Y-shaped pipe 802 for storage, thus completing the automatic cleaning of impurities and reducing the burden on the staff.
