Description

Technical Field

[0001] This utility model relates to the field of infrared spectrophotometer technology, specifically to a tablet pressing device for an infrared spectrophotometer. Background Technology

[0002] The pelleting device of an infrared spectrophotometer is mainly used to mix the sample with a potassium bromide (KBr) matrix and press it into a transparent sheet for infrared transmission spectroscopy analysis. The pelleting mold is usually made of stainless steel and includes a base, a push rod, and a mold sleeve. The sample and KBr powder are placed in the mold sleeve and a uniform sheet is formed by pressure.

[0003] Currently, when grinding potassium bromide powder is poured into the mold, the small aperture of the mold not only makes it difficult to insert the potassium bromide, but also makes it easy for the potassium bromide to fall onto the edge of the mold hole wall. In view of this, we propose a tablet pressing device for an infrared spectrophotometer. Utility Model Content

[0004] The purpose of this invention is to provide a tablet pressing device for an infrared spectrophotometer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tablet pressing device for an infrared spectrophotometer, comprising a main frame, an annular slide rail fixedly installed between the inner walls of both sides of the main frame, an mounting frame slidably installed on the inner side wall of the annular slide rail, a hollow guide tube slidably installed through one end of the mounting frame, a guide rod slidably installed through the other end of the mounting frame, a first limiting block fixedly installed at the upper end of both the guide rod and the hollow guide tube, and a metal funnel slidably installed through the top of the first limiting block on the right side;

[0007] Preferably, a servo motor is fixedly installed on the inner wall of the top of the main frame. The output end of the servo motor is fixedly connected to the mounting bracket and is located in the middle of the guide rod and the hollow guide tube. The central axis of the output end of the servo motor coincides with the central axis of the annular slide rail.

[0008] Preferably, the first hydraulic cylinder, the second hydraulic cylinder, and the guide rod are vertically aligned, and the outer diameter of the pressure head mold is the same as that of the clamping block.

[0009] Preferably, an electric slide rail is fixedly installed on the rear side of the bottom inner wall of the main frame, and a mold sleeve is fixedly installed on the slider part of the electric slide rail. The central axes of the mold sleeve, the pressure head mold, and the hollow guide tube are in the same vertical plane, and the inner diameter of the mold sleeve is the same as that of the pressure head mold.

[0013] Compared with the prior art, this utility model provides a tablet pressing device for an infrared spectrophotometer, which has the following beneficial effects:

[0014] 1. The tablet pressing device of this infrared spectrophotometer activates the electric slide rail and controls the mold sleeve to move directly below the hollow feed tube. Then, the ground potassium bromide powder is poured into the metal funnel. The potassium bromide powder falls into the inner hole of the mold sleeve through the inner hole of the metal funnel and the hollow feed tube. When potassium bromide powder adheres to the inner wall of the metal funnel and the hollow feed tube, the metal funnel can be pressed down to compress the spring. Then, the hand pressing the metal funnel is lifted. The hollow feed tube and the metal funnel will then spring back under the action of the spring and vibrate up and down, thereby shaking the potassium bromide powder on the inner wall into the mold sleeve.

[0015] 2. The tablet pressing device of this infrared spectrophotometer controls the servo motor to rotate at a specified angle, causing the mounting bracket to slide along the inner wall of the annular slide rail until the metal funnel moves to the front side and stops. This facilitates the unblocking and cleaning of the inner hole of the metal funnel and the hollow feed tube, preventing potassium bromide powder from adhering to the inner wall.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please refer to Figure 1-5 The tablet pressing device for an infrared spectrophotometer includes a main frame 1. An annular slide rail 9 is fixedly installed between the inner walls of the two sides of the main frame 1. An mounting frame 8 is slidably installed on the inner side wall of the annular slide rail 9. A hollow guide tube 18 is slidably installed through one end of the mounting frame 8, and a guide rod 14 is slidably installed through the other end of the mounting frame 8. A first limiting block 12 is fixedly installed at the upper end of both the guide rod 14 and the hollow guide tube 18. A metal funnel 16 is slidably installed through the top of the first limiting block 12 on the right side.

[0029] The second hydraulic cylinder 7 is fixedly installed on the outer wall of the bottom of the main frame 1. The output end of the second hydraulic cylinder 7 passes through the main frame 1, and a mold base 11 is fixedly installed on the output end of the second hydraulic cylinder 7. A locking block 10 is fixedly installed on the other side of the mold base 11. The first hydraulic cylinder 2 is fixedly installed on the top outer wall of the main frame 1, and its output end passes through the main frame 1. A first pressure block 3 is fixedly installed on the output end of the first hydraulic cylinder 2. A pressure head mold 15 is fixedly installed at the lower end of the guide rod 14. More specifically, by controlling the servo motor 4 to rotate at a specified angle, the mounting bracket 8 slides along the inner wall of the annular slide rail 9 until the metal funnel 16 moves to the front side and stops, which facilitates the unblocking and cleaning of the inner hole of the metal funnel 16 and the hollow guide tube 18.

[0030] In this embodiment, a servo motor 4 is fixedly installed on the top inner wall of the main frame 1. The output end of the servo motor 4 is fixedly connected to the mounting bracket 8 and is located in the middle of the guide rod 14 and the hollow guide tube 18. The central axis of the output end of the servo motor 4 coincides with the central axis of the annular slide rail 9. More specifically, through the symmetrical design, the device is more stable and has less vibration when the servo motor 4 drives the mounting bracket 8 to rotate.

[0031] In this embodiment, the first hydraulic cylinder 2, the second hydraulic cylinder 7, and the guide rod 14 are vertically aligned, and the outer diameters of the pressure head mold 15 and the clamping block 10 are the same. More specifically, both the pressure head mold 15 and the clamping block 10 can mate with the inner holes at both ends of the mold sleeve 6.

[0032] In this embodiment, an electric slide rail 5 is fixedly installed on the rear side of the bottom inner wall of the main frame 1. A mold sleeve 6 is fixedly installed on the slider part of the electric slide rail 5. The inner hole of the mold sleeve 6 is not connected vertically. The central axes of the mold sleeve 6, the pressure head mold 15, and the hollow guide tube 18 are in the same vertical plane. The inner diameter of the mold sleeve 6 is the same as that of the pressure head mold 15. More specifically, by controlling the operation of the electric slide rail 5, the mold sleeve 6 can be controlled to move directly below the pressure head mold 15 or the hollow guide tube 18.

[0033] In this embodiment, the lower port of the metal funnel 16 is connected to the upper port of the hollow guide tube 18, and the lower end of the hollow guide tube 18 has the same specifications as the pressure head mold 15. More specifically, the ground potassium bromide powder is poured into the metal funnel 16. At this time, the potassium bromide powder will fall into the inner hole of the mold sleeve 6 through the inner hole of the metal funnel 16 and the hollow guide tube 18, which facilitates the pouring of potassium bromide powder.

[0034] In this embodiment, springs 13 are fitted on the outer walls of both the guide rod 14 and the hollow guide tube 18. The two ends of the springs 13 contact the first limiting block 12 and the mounting bracket 8, respectively. More specifically, the springs 13 reset the guide rod 14 and the hollow guide tube 18. Then, by pressing down on the metal funnel 16 and compressing the springs 13, and then lifting the hand that was pressing the metal funnel 16, the hollow guide tube 18 and the metal funnel 16 will spring back under the action of the springs 13 and vibrate up and down, thereby shaking the potassium bromide powder on the inner wall into the mold sleeve 6.

[0035] In this embodiment, a second limiting block 17 is fixedly installed on the outer wall of both the guide rod 14 and the hollow guide tube 18, and the second limiting block 17 contacts the mounting bracket 8. More specifically, the second limiting block 17 has a limiting effect on the guide rod 14 and the hollow guide tube 18, and restricts the state of the spring 13, so that the spring 13 is always in a compressed state.

[0036] In actual operation, when this device is used, firstly, the electric slide rail 5 is activated, and the mold sleeve 6 is moved to directly below the hollow guide tube 18, so that the lower end of the hollow guide tube 18 is aligned vertically with the inner hole of the mold sleeve 6. Then, the ground potassium bromide powder can be poured into the metal funnel 16. At this time, the potassium bromide powder will fall into the inner hole of the mold sleeve 6 through the metal funnel 16 and the inner hole of the hollow guide tube 18. When potassium bromide powder adheres to the inner wall of the metal funnel 16 and the hollow guide tube 18, the metal funnel 16 can be pressed down to compress the spring 13, and then the hand pressing the metal funnel 16 can be lifted. Then, the hollow guide tube 18 and the metal funnel 16 will spring back under the action of the spring 13 and vibrate up and down, thereby shaking the potassium bromide powder on the inner wall into the mold sleeve 6. Inside the sleeve 6, the mold sleeve 6 is controlled to move to the top of the mold base 10 and then stops. Next, the second hydraulic cylinder 7 is controlled to extend, causing the mold base 10 and mold base 11 to move upward until the mold base 10 is inserted into the inner hole at the bottom of the mold sleeve 6 and the mold base 11 contacts the bottom of the mold sleeve 6 and stops. Finally, the first hydraulic cylinder 2 is controlled to extend, causing the first pressure block 3 to press down the first limit block 12 and compress the spring 13. At this time, the pressure head mold 15 will be inserted into the inner hole at the top of the mold sleeve 6 and apply pressure to the potassium bromide powder, thereby achieving tableting. By controlling the servo motor 4 to rotate at a specified angle, the mounting bracket 8 slides along the inner wall of the annular slide rail 9 until the metal funnel 16 moves to the front and stops, which facilitates the unblocking and cleaning of the inner hole of the metal funnel 16 and the hollow guide tube 18.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
