Description

Technical Field

[0001] This utility model relates to the technical field of chromatography equipment, and in particular to a multifunctional dynamic axial column packing machine. Background Technology

[0002] An axial packing machine is a device used to pack packing material into a chromatographic column. It is mainly used in liquid chromatography and gas chromatography in the field of chemical analysis. This machine ensures that the packing material is uniformly and tightly packed into the column by applying pressure in the axial direction of the chromatographic column, thereby ensuring the separation effect.

[0003] Traditional column packing methods rely mainly on manual operation, such as manually packing and compacting chromatographic packing materials. The operation process is cumbersome, time-consuming, labor-intensive, and the quality is difficult to guarantee. In addition, the pressure inside the chromatographic column varies greatly, which can lead to problems such as packing material loss and column deformation, affecting the performance and stability of the chromatographic column. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes a multifunctional dynamic axial column loading machine. The clamping component facilitates the fixing of the end of the forming tube, the driving component drives the forming wheel to rotate, and the feeding unit feeds the forming tube, effectively ensuring the efficiency of bending the tube. In addition, the feeding unit achieves the purpose of automatically feeding the bending tube through a compact mechanical structure, avoiding the use of electrical equipment and saving resources.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a multifunctional dynamic axial column loading machine, including a support base, a support frame fixedly disposed at the middle of the rear end of the support base, a mounting groove disposed at the middle of the support base, a sealing element disposed in the mounting groove, a support ring disposed in the lower part of the support frame and coaxially disposed with the mounting groove, a push rod coaxially disposed with the support ring, and a pushing assembly for pushing the push rod, wherein a chromatographic column body is disposed in the mounting groove.

[0006] By adopting the above technical solution, the sealing component facilitates sealing of the lower end face of the chromatographic column body, the support ring clamps and fixes the outer periphery of the chromatographic column body, and the pushing component pushes the push rod to squeeze the packing material inside the chromatographic column body. This facilitates the application of axial pressure to the chromatographic column body to ensure that the packing material is uniformly and tightly packed inside the column. Compared with manual packing, it can provide a consistent pressure distribution, ensure uniform distribution of packing particles, reduce column efficiency variability, and make the mechanized packing process faster and more stable.

[0007] As a preferred embodiment, the mounting groove is configured to be semi-through, and the inner wall of the mounting groove is configured to be a smooth arc surface.

[0008] By adopting the above technical solution, the design of the mounting groove enables the chromatographic column body to be assembled and sealed more conveniently and stably. Its semi-through structure can firmly support the lower end face of the chromatographic column body, preventing shaking and falling off, while the smooth arc inner wall can reduce the friction between the chromatographic column body and the mounting groove, improving the efficiency of installation and disassembly.

[0009] As a preferred embodiment, the sealing element includes a sealing plug disposed in the mounting groove and a sealing column disposed in the inner cavity of the sealing plug. The outer periphery of the sealing plug is tangential to the inner wall of the mounting groove, and the outer periphery of the sealing column is tangential to the inner cavity of the chromatographic column body.

[0010] By adopting the above technical solution, the sealing component achieves complete sealing and isolation of the chromatographic column body by installing the sealing plug in the mounting groove and tightly tangent to the inner wall of the groove, and then placing the sealing column in the inner cavity of the sealing plug so that its outer circumference is tightly tangent to the inner cavity of the chromatographic column body. This effectively prevents fluid leakage at the connection part of the chromatographic column, thereby ensuring the normal operation of the chromatographic column and the accuracy of the results.

[0011] As a preferred embodiment, the inner wall of the support ring is tangential to the outer periphery of the chromatographic column body, and the inner wall of the support ring is provided with a rubber ring.

[0012] By adopting the above technical solution, and by setting the inner wall of the support ring tangentially to the outer periphery of the chromatographic column body, and by setting a rubber ring on the inner wall of the support ring, the problem of poor fixation reliability of the chromatographic column body is solved, effectively preventing loosening between the chromatographic column body and the support ring, and ensuring the stable operation of the chromatographic column body.

[0013] As a preferred embodiment, support rods are fixedly provided on both sides of the support ring, and the end of the support rod that is connected away from the support ring is fixedly connected to the support frame.

[0014] By adopting the above technical solution, the stability of the chromatographic column body is improved by fixing support rods on both sides of the support ring. These support rods are fixedly connected to the support frame away from the support ring connection end, forming a clamping structure. When the chromatographic column body is embedded in the support ring, the support rods will act as a fixing device through the connection with the support frame.

[0015] As a preferred embodiment, the push rod includes a push rod and a sealing ring disposed at one end of the push rod relative to the column body, the sealing ring being made of rubber.

[0016] By adopting the above technical solution, when the support rod is pushed forward, the sealing ring can ensure that the sample flows smoothly in the chromatographic column, while preventing any leakage, ensuring the sealing of the chromatographic column, and effectively improving the chromatographic separation effect and analytical accuracy.

[0017] As a preferred embodiment, the pushing assembly includes a slider fixedly disposed at the other end of the pushing support rod, connecting rods fixedly disposed on both sides of the upper end face of the slider, and an electric telescopic shaft connected to each of the connecting rods, wherein the end of the electric telescopic shaft away from the connecting rod is fixedly connected to the support frame.

[0018] By adopting the above technical solution, the support frame is precisely pushed by a slider fixed to the other end of the push rod, connecting rods fixed to both sides of the upper end face of the slider, and an electric telescopic shaft component connected to each connecting rod, thereby realizing the push rod's movement within the chromatographic column body cavity.

[0019] As a preferred embodiment, the system further includes a slide groove on the support frame that is adapted to the slider, the slide groove being arranged in the height direction of the support frame.

[0020] By adopting the above technical solution, and by setting a groove on the support frame that is aligned with the height direction of the slider, the movement stability and accuracy of the slider are improved.

[0037] like Figures 1 to 4 As shown, a multifunctional dynamic axial column packing machine includes a support base 1, a support frame 2 fixedly disposed at the middle of the rear end of the support base 1, a mounting groove 10 disposed at the middle of the support base 1, a sealing element 7 disposed in the mounting groove 10, a support ring 5 disposed in the lower part of the support frame 2 and coaxially disposed with the mounting groove 10, a push rod 4 coaxially disposed with the support ring 5, and a pushing assembly for pushing the push rod 4. A chromatographic column body 100 is disposed in the mounting groove 10. In this invention, the sealing element 7 facilitates sealing of the lower end face of the chromatographic column body 100, the support ring 5 clamps and fixes the outer periphery of the chromatographic column body 100, and the pushing assembly pushes the push rod 4 to squeeze the packing material in the chromatographic column body 100, thereby facilitating the application of axial pressure to the chromatographic column body 100 to ensure that the packing material is uniformly and tightly packed in the column. Compared with manual packing, it can provide a consistent pressure distribution, ensure uniform distribution of packing particles, reduce column efficiency variability, and the mechanized packing process is faster and more stable.

[0038] Please refer to details. Figure 1 , Figure 2 , Figure 3 and Figure 4 A multifunctional dynamic axial column packing machine includes a support base 1, a support frame 2 fixedly disposed at the middle of the rear end of the support base 1, and a mounting groove 10 disposed at the middle of the support base 1. The mounting groove 10 is semi-through, and the inner wall of the mounting groove 10 is a smooth arc surface. This design of the mounting groove 10 allows the chromatographic column body 100 to be assembled and sealed more conveniently and stably. Its semi-through structure can firmly support the lower end face of the chromatographic column body 100, preventing shaking and falling off, while the smooth arc inner wall can reduce the friction between the chromatographic column body 100 and the mounting groove 10, improving the efficiency of installation and disassembly. At the same time, the sealing element 7 inside the mounting groove 10 can perfectly seal the chromatographic column body 100 and the mounting groove 10, ensuring that the components do not leak during the experiment, effectively improving the service life of the chromatographic column body 100 and the accuracy of the experimental results.

[0039] Please refer to details. Figure 4A sealing element 7 is disposed within the mounting groove 10. The sealing element 7 includes a sealing plug disposed within the mounting groove 10 and a sealing column 71 disposed within the cavity of the sealing plug. The outer periphery of the sealing plug is tangential to the inner wall of the mounting groove 10, and the outer periphery of the sealing column 71 is tangential to the inner cavity of the chromatographic column body 100. By installing the sealing plug within the mounting groove 10 and ensuring its outer periphery is tightly tangential to the inner wall of the groove, and then placing the sealing column 71 within the cavity of the sealing plug and ensuring its outer periphery is tightly tangential to the inner cavity of the chromatographic column body 100, the sealing element 7 achieves complete sealing and isolation of the chromatographic column body 100, effectively preventing fluid leakage at the column connection, thereby ensuring the normal operation of the chromatographic column and the accuracy of the results. Its working principle lies in the tight fit between the sealing plug and the mounting groove 10, and between the sealing column 71 and the chromatographic column body 100, forming a robust sealing barrier that prevents media leakage and the ingress of external contaminants. During use, due to the precise fit between the sealing plug and the mounting groove 10, and between the sealing column 71 and the chromatographic column body 100, the chromatographic column can be effectively isolated, ensuring that the fluid flows only within the chromatographic column cavity without leakage, thereby guaranteeing the sealing performance of the chromatographic column and improving the accuracy and reliability of chromatographic analysis.

[0040] Please refer to details. Figure 1 , Figure 2 and Figure 3 A support ring 5 is disposed in the lower part of the support frame 2 and coaxially with the mounting groove 10. The inner wall of the support ring 5 is tangential to the outer periphery of the chromatographic column body 100, and a rubber ring is provided on the inner wall of the support ring 5. By tangenting the inner wall of the support ring 5 to the outer periphery of the chromatographic column body 100 and providing a rubber ring on the inner wall of the support ring 5, the problem of poor fixation reliability of the chromatographic column body 100 is solved, effectively preventing loosening between the chromatographic column body 100 and the support ring 5, and ensuring the stable operation of the chromatographic column body 100. This structure significantly enhances the connection reliability between the chromatographic column body 100 and the support ring 5, and can effectively prevent problems such as detachment and movement during the operation of the chromatographic column body 100, ensuring the smoothness and accuracy of the operation of the chromatographic column body 100.

[0041] Please refer to details. Figure 1 , Figure 2 and Figure 3 To ensure the stability of the support ring 5 in clamping and fixing the chromatographic column body 100, support rods are fixedly installed on both sides of the support ring 5. The end of the support rod that is away from the support ring 5 is fixedly connected to the support frame 2. By fixing support rods on both sides of the support ring 5, the stability of the chromatographic column body 100 is improved. These support rods are fixedly connected to the support frame 2 at the end away from the support ring 5, forming a clamping structure. When the chromatographic column body 100 is embedded in the support ring 5, the support rods will act as a fixing device through their connection with the support frame 2.

[0042] Please refer to details. Figure 1 , Figure 2 and Figure 3 A push rod 4, coaxially arranged with the support ring 5, includes a push support rod 41 and a sealing ring 411 located at one end of the push support rod 41 relative to the column body 100. The sealing ring 411 is made of rubber. When the push support rod 41 moves forward, the sealing ring 411 ensures that the sample flows smoothly within the column while preventing any leakage, thus guaranteeing the column's airtightness and effectively improving chromatographic separation and analytical accuracy. This simple structural design effectively solves the sealing problem of traditional chromatographic columns, improving the efficiency and accuracy of chromatographic experiments.

[0043] Please refer to details. Figure 1 , Figure 2 and Figure 3 A pushing assembly for pushing the push rod 4 includes a slider 3 fixedly mounted on the other end of the pushing support rod 41, connecting rods 611 fixedly mounted on both sides of the upper end face of the slider 3, and an electric telescopic shaft 61 connected to each connecting rod 611. The end of the electric telescopic shaft 61 connected away from the connecting rod 611 is fixedly connected to the support frame 2. Through the slider 3 fixed on the other end of the pushing support rod 41, the connecting rods 611 fixed on both sides of the upper end face of the slider 3, and the electric telescopic shaft 61 connected to each connecting rod 611, the support frame 2 is precisely pushed, thereby pushing the push rod 4 within the cavity of the chromatographic column body 100. Its working principle is as follows: when the electric telescopic shaft 61 extends, the connecting rods 611 move accordingly, pushing the slider 3 to move along the direction of the pushing support rod 41, ultimately achieving the purpose of pushing the support frame 2; conversely, when the electric telescopic shaft 61 retracts, the slider 3 will return to the initial position, thereby achieving the automatic reset of the support frame 2.

[0044] Please refer to details. Figure 1 , Figure 2 and Figure 3 To ensure the stability of the slider 3 during axial movement, a groove 21 adapted to the slider 3 is also provided on the support frame 2. The groove 21 is set in the height direction of the support frame 2. By setting a groove 21 on the support frame 2 that is consistent with the height direction of the slider 3, the movement stability and accuracy of the slider 3 are improved. When the slider 3 moves along the support frame 2, it will always cooperate with the groove 21 to maintain a smooth and stable state, and finally achieve the purpose of axial movement.

[0045] In this embodiment, the chromatographic column body 100 is placed in the mounting groove 10, the sealing member 7 ensures the sealing of the lower end face of the chromatographic column, the support ring 5 is coaxially arranged with the mounting groove 10 to clamp and fix the outer periphery of the chromatographic column body 100, and the push rod 4 is coaxial with the support ring 5. When the electric telescopic shaft 61 extends, the connecting rod 611 moves accordingly, pushing the slider 3 to move along the direction of the push support rod 41, squeezing the packing inside the chromatographic column, and then applying axial pressure to make the packing uniformly and tightly fill the column. In this way, the mechanized filling process is faster and more stable. By changing the force of the push component, the packing density can be adjusted to achieve precise control of the packing under different experimental conditions.

[0046] Conversely, when the electric telescopic shaft 61 retracts, the slider 3 will return to its initial position, thereby achieving automatic reset of the support frame 2 and driving the push rod 4 to leave the inner cavity of the chromatographic column body 100.

[0047] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
