Description

Technical Field

[0001] The present application relates to the technical field of target plate drying, and in particular to a target plate drying device for liquid chromatography. Background Art

[0002] Currently, liquid chromatography target plates usually need to be kept dry during testing. In liquid chromatography analysis, samples are separated and transferred to the target plate for subsequent analysis or testing. If there is residual moisture or other volatiles on the target plate, they may interact with the compounds in the sample, resulting in inaccurate analysis results. Keeping the target plate dry can ensure the purity of the sample and reduce errors caused by moisture or volatiles. Therefore, in liquid chromatography analysis, a target plate drying device is usually used to remove residual moisture on the target plate to ensure the accuracy and reliability of the analysis.

[0003] Through searching, a Chinese patent with the Chinese patent announcement number of "CN213527465U" discloses an automatic target plate drying device, which includes a shell, a drying chamber is arranged in the shell, a drawer-type loading platform is arranged in the drying chamber, the drawer-type loading platform is slidably connected with the drying chamber, the drawer-type loading platform is used to place the target plate, a driving mechanism is arranged in the drying chamber, the driving mechanism is transmission-connected with the drawer-type loading platform, a negative pressure mechanism is arranged below the drying chamber, and the negative pressure mechanism is used to evacuate the drying chamber. The utility model adopts a drawer-type loading platform, which enters and exits the drying chamber driven by the driving mechanism; the target plate can be placed on the drawer-type loading platform to achieve the replacement of the target plate; the negative pressure mechanism is used to evacuate the drying chamber to form a negative pressure, accelerate air convection, and use an electromagnetic valve to control the air convection speed to ensure the steady and rapid volatilization of the liquid, thereby achieving rapid drying of the target plate. The utility model ensures the drying effect of the target plate, has a simple structure and strong practicality.

[0004] With respect to the above-mentioned related technologies, the utility model inventor found the following defects:

[0005] Although the above device can assist in automatically drying the target plate during use, during the drying process, the target plate is in a static state, and the surface structure of the target plate is relatively complex, with many cracks and gaps on its surface. It can be seen that during the overall drying of the static target plate, its tiny gaps cannot be carefully dried. It can be seen that the overall drying is not comprehensive enough and drying gaps are very likely to occur, so it needs to be improved. Utility Model Content

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The present application embodiment discloses a target plate drying device for liquid chromatography. Figure 1 As shown, it includes a base 1 and a target plate body 2, support legs 3 are fixedly installed at the four corners of the top of the base 1, a chassis 4 is fixedly installed on the top of the support legs 3, drying components 5 are fixedly installed on both sides of the chassis 4, a driving mechanism 6 is fixedly installed in the middle of the rear side of the chassis 4, a displacement mechanism 7 is fixedly installed in the middle of the chassis 4, a rotating mechanism 8 is fixedly installed on the rear side of the displacement mechanism 7, and positioning mechanisms 9 are fixedly installed on the upper and lower ends of the front of the rotating mechanism 8, and the target plate body 2 is placed on the inner side of the positioning mechanism 9;

[0033] The rotating mechanism 8 includes a vertical rod 81, which is fixedly installed at the rear end of the inner side of the displacement mechanism 7. A guide rail 82 is fixedly installed in the middle of the vertical rod 81, and a first motor 83 is fixedly installed at one end of the guide rail 82. The output end of the first motor 83 passes through the guide rail 82 and is fixedly installed with a first screw rod 84. The outer surface of the first screw rod 84 is threadedly connected with a slider 85. The first screw rod 84 is rotatably connected to the inner side of the guide rail 82, and the slider 85 is slidably connected to the inside of the guide rail 82. A linkage component 86 is movably installed on the front of the slider 85, and the front of the linkage component 86 is fixedly connected to the rear side of the positioning mechanism 9. The device body is composed of a base 1, a supporting leg 3, a chassis 4 and other components, wherein the drying component 5, the driving mechanism 6, the displacement mechanism 7 and the rotating mechanism 8 are integrated inside the chassis 4 to form a complete The target plate drying system, the coordinated work of the displacement mechanism 7 and the rotation mechanism 8 enables the target plate to achieve multi-angle rotation during the drying process, greatly improving the contact area between the target plate and the drying hot air, thereby ensuring the uniformity and efficiency of drying. The design of the positioning mechanism 9 enables target plates of different sizes to be stably fixed inside the device, avoiding problems such as uneven drying or target plate damage caused by target plate shaking. In addition, the setting of the linkage component 86 enables the reciprocating sliding of the slider 85 to synchronously drive the two sets of rotating wheels 863 to rotate, thereby driving the positioning mechanism 9 and the target plate to rotate. This design not only simplifies the operation process, but also improves the overall stability and reliability of the device. The device achieves rapid, uniform and efficient drying of the target plate through reasonable structural design and functional configuration.

[0034] Please refer to Figure 5The displacement mechanism 7 includes side rails 71, which are fixedly installed in the middle of the top and the middle of the bottom of the chassis 4. The inside of the side rails 71 is rotatably connected to the second screw rod 72, and the outer surface of the second screw rod 72 is threadedly connected to the sliding rod 73. The inner rear end of the sliding rod 73 is fixedly connected to the vertical rod 81, and the rear end of the second screw rod 72 is fixedly connected to the driving mechanism 6. The side rails 71 are firmly installed at the top and bottom center positions inside the chassis 4, providing solid support for the entire displacement mechanism 7. The second screw rod 72 is the core component of the displacement mechanism 7, and its rotation is connected to the inside of the side rails 71. It is driven by the driving mechanism 6 to achieve rotational movement. When the second screw rod 72 rotates, the sliding rod 73 threadedly connected to its outer surface will move along the axial direction of the screw rod. The displacement mechanism realized by the threaded connection between the screw rod and the slide rod 73 has the characteristics of accurate positioning and smooth movement. The inner rear end of the slide rod 73 is fixedly connected to the vertical rod 81. Therefore, when the slide rod 73 moves in the side rail 71, it will drive the vertical rod 81 and the rotating mechanism 8 and positioning mechanism 9 connected thereto to move together. This design enables the device to achieve precise position adjustment of the target plate inside the chassis 4 to adapt to target plates of different sizes or different drying requirements. The driving mechanism 6 is fixedly connected to the rear end of the second screw rod 72 to provide power for the rotation of the second screw rod 72. Through the control of the driving mechanism 6, the rotation speed and direction of the second screw rod 72 can be accurately controlled, thereby achieving accurate control of the moving speed and direction of the slide rod 73.

[0035] Please refer to Figure 3-Figure 8 The linkage assembly 86 includes a side rod 861 and an articulated seat 862. The side rod 861 is fixedly installed at the upper and lower ends of the vertical rod 81. The inner end of the side rod 861 is rotatably connected to a rotating wheel 863. The back of the rotating wheel 863 is rotatably connected to a linkage rod 864. The articulated seat 862 is fixedly installed at the upper and lower ends of the front of the slider 85. The articulated seat 862 and the outer end of the linkage rod 864 are hinged. The linkage rod 864 is a key component. The back of the linkage rod 864 is rotatably connected to the rotating wheel 863, and the outer end is hinged to the articulated seat 862. This design makes it possible for the slider 85 to be moved when it is inside the guide rail 82. When sliding back and forth, the articulated seat 862 can push the linkage rod 864 to move, thereby driving the rotating wheel 863 to rotate. Since the slider 85 slides back and forth, the rotating wheel 863 will also rotate continuously accordingly, thereby driving the positioning mechanism 9 and the target plate to rotate. This linkage mechanism not only ensures the uniform rotation of the target plate during the drying process and improves the drying efficiency, but also makes the operation of the entire device easier and more reliable. At the same time, the structural design of the linkage component 86 also takes into account durability and ease of maintenance, providing a guarantee for the long-term stable operation of the device.

[0036] Please refer to Figure 6The driving mechanism 6 includes a fixed plate 61 and a worm gear 62. The worm gear 62 is rotatably connected to the upper and lower ends of the back side of the chassis 4. The front side of the worm gear 62 is fixedly connected to the rear end of the second screw rod 72. The fixed plate 61 is fixedly installed on the top rear side and the bottom rear side of the chassis 4. A second motor 63 is fixedly installed on the top of the fixed plate 61 at the top of the displacement. The output end of the second motor 63 is fixedly connected to a worm 65. The two sets of worm gears 65 are fixedly connected by a connecting shaft 64. The worm gear 62 is cleverly rotatably connected to the upper and lower ends of the back side of the chassis 4, and its front side is fixedly connected to the rear end of the second screw rod 72. This design makes it possible to directly drive the second screw rod 72 to rotate when the worm gear 62 rotates, thereby driving the sliding rod 73 to move in the side rail 71. The structure of the worm gear 62 and the worm 65 is self-locking, which can ensure that when the drive stops, the sliding rod 73 can maintain the current position without accidental movement. The fixed plate 61 serves as a support The supporting components are firmly mounted on the top rear side and the bottom rear side of the chassis 4. A second motor 63 is fixedly mounted on the fixed plate 61 at the top. The motor provides power for the entire driving mechanism 6. The output end of the second motor 63 is fixedly connected to a worm 65, and the two groups of worms 65 are fixedly connected by a connecting shaft 64, ensuring that the two worms 65 can rotate synchronously. This design not only simplifies the structure, but also improves the reliability and stability of the device. When the second motor 63 is started, it will drive a worm 65 to rotate. Since the two groups of worms 65 are connected by a connecting shaft 64, the two worms 65 will rotate synchronously. The rotation of the worm 65 will drive the worm wheel 62 meshing therewith to rotate, and then drive the sliding rod 73 to move through the second lead screw 72. In this way, the driving mechanism 6 can achieve precise control of the displacement mechanism 7 to ensure that the target plate can achieve uniform rotation and precise position adjustment during the drying process.

[0037] Please refer to Figure 2 A protective screen 53 is fixedly installed at the inner end of the drying bucket 51, and the overall cross-sectional shape of the drying bucket 51 is an isosceles trapezoid. A protective screen 53 is fixedly installed at the inner end of the drying bucket 51. This design can ensure that the hot air is evenly distributed and diffused inside the drying bucket 51, further improving the uniformity and efficiency of drying. At the same time, the overall cross-sectional shape of the drying bucket 51 adopts an isosceles trapezoidal design, which has excellent guiding and diffusive properties. The upper base of the isosceles trapezoid is narrower and the lower base is wider, so that after the hot air is output from the hot air blower 52, it can form a gradual diffusion effect inside the drying bucket 51, increase the contact area between the hot air and the target plate, and improve the drying effect. In addition, the isosceles trapezoidal structure also has a certain stability, can resist a certain degree of external impact and vibration, and ensure the stable operation of the drying component 5.

[0038] Please refer to Figure 1A box door 10 is hingedly installed at the front end of one side of the chassis 4. The outer end of the box door 10 is magnetically connected to the chassis 4 through a magnetic plate, and the box door 10 is installed in a hinged manner. This design allows the box door 10 to be flexibly opened and closed, which is convenient for users to observe and operate the target plates and components inside the chassis 4. The outer end of the box door 10 also adopts a magnetic connection with the chassis 4 using a magnetic plate. This design not only enhances the closing tightness of the box door 10, effectively prevents the leakage of hot air during the drying process, thereby ensuring the maximization of drying efficiency and energy utilization, but also provides users with a simple and safe way to fix the box door 10, without the need for additional locks or fasteners, reducing the complexity of operation. At the same time, the magnetic connection also has good durability and reliability, and can maintain a stable connection effect during long-term use, reducing the maintenance and replacement costs caused by loosening or damage of the box door 10.

[0039] Please refer to Figure 2 The drying assembly 5 includes a drying bucket 51, which is fixedly installed in the middle of both sides of the chassis 4. The inner side of the drying bucket 51 is connected to the interior of the chassis 4. A hot air blower 52 is fixedly installed on the outer side of the drying bucket 51. The output end of the hot air blower 52 is connected to the interior of the chassis 4 through the drying bucket 51. The drying assembly 5 is mainly composed of a drying bucket 51 and a hot air blower 52. The drying bucket 51 is firmly installed in the middle of both sides of the chassis 4, and its inner side is connected to the interior of the chassis 4, forming a smooth hot air circulation channel. This design allows the hot air generated by the hot air blower 52 to directly enter the interior of the chassis 4 through the drying bucket 51, and the target plate is dried in all directions. The hot air blower 52, as the core component of the drying assembly 5, is fixedly installed on the outer side of the drying bucket 51, and its output end is connected to the drying bucket 51 and the interior of the chassis 4. The parts are interconnected, ensuring a continuous supply and uniform distribution of hot air. By starting the hot air blower 52, the hot air can be sent into the interior of the chassis 4, and the target plate can be efficiently dried by utilizing the flow and diffusion of the hot air. In addition, the position layout of the drying component 5 has also been carefully considered. The drying bucket 51 is installed in the middle of both sides of the chassis 4, so that the hot air can form convection inside the chassis 4, thereby improving the uniformity and efficiency of drying. At the same time, the fixed installation of the hot air blower 52 and the drying bucket 51 also ensures the stability and durability of the entire drying component 5. The drying component 5 provides a stable and efficient hot air supply for the drying of the target plate through reasonable structural design and functional configuration. Its high efficiency and uniformity ensure that the target plate can quickly reach the required degree of drying during the drying process, thereby improving the overall performance and use effect of the device.

[0040] Please refer to Figure 7The positioning mechanism 9 includes a frame seat 91, which is fixedly mounted on the front side of the rotating wheel 863. A limiting component 92 is fixedly mounted on one side of the frame seat 91. The target plate body 2 is installed inside the frame seat 91 through the limiting component 92. The design of the positioning mechanism 9 ensures the stability and position accuracy of the target plate during the drying process. The mechanism is mainly composed of the frame seat 91 and the limiting component 92, which work together to achieve the fixation and positioning of the target plate. The frame seat 91, as the basic component of the positioning mechanism 9, is firmly mounted on the front side of the rotating wheel 863. The design takes into account the size and shape of the target plate to ensure that the target plate can be completely placed inside the frame seat 91 and maintain a certain stability. The structure of the frame seat 91 also has a certain strength and rigidity. The frame seat 91 has a fixed structure and a fixed material, and the ...

[0041] Please refer to 8. The outer end of the limit frame 923 passes through the outer rail 921 and is fixedly installed with a push plate 924. The outer surfaces of the frame seat 91 and the outer rail 921 are evenly spaced with air holes 93. The outer end of the limit frame 923 is fixedly installed with a push plate 924 by passing through the outer rail 921. This design allows the user to easily move the limit frame 923 by pushing the push plate 924 when installing or removing the target plate, thereby facilitating the insertion and removal of the target plate. The position and size of the push plate 924 are reasonably designed, which will not hinder the fixation of the target plate and ensure that the user can operate it conveniently. At the same time, the outer surfaces of the frame seat 91 and the outer rail 921 are evenly spaced with air holes 93. The setting of these air holes 93 allows hot air to pass through the frame seat 91 and the outer rail 921 smoothly, and the target plate is dried in all directions. The reasonable layout of the air holes 93 not only ensures the fluidity of the hot air, but also avoids the hot air from directly impacting the target plate, thereby ensuring the uniformity and efficiency of the drying.

[0042] Please refer to Figure 8The limit assembly 92 includes an outer rail 921, which is fixedly mounted on one side of the frame seat 91. Limit springs 922 are fixedly mounted on both ends of the inner part of the outer rail 921. The end of the limit spring 922 is fixedly mounted on a limit frame 923. The cross-sectional shape of the limit frame 923 is L-shaped. The limit frame 923 target plate body 2 is inserted between the limit frame 923 and the inner side of the frame seat 91. The outer rail 921 is stably mounted on one side of the frame seat 91 as the basic structure of the limit assembly 92. Its design takes into account the size and shape of the target plate, and provides a suitable installation position for the limit spring 922 and the limit frame 923. The limit springs 922 are mounted on both ends of the inner part of the outer rail 921. They not only play a buffering role, but also reduce the impact force when the target plate is inserted. It can also provide a certain pressing force after the target plate is fixed to ensure that the target plate will not loosen due to vibration during the drying process. The limit frame 923 is the core component of the limit assembly 92, and its cross-sectional shape is L-shaped, which can effectively limit the lateral movement of the target plate and facilitate the insertion and fixation of the target plate. One end of the limit frame 923 is fixedly connected to the limit spring 922, and the other end forms a plug-in space with the inner side of the frame seat 91. The target plate is plugged into this space. This design enables the target plate to be smoothly inserted into the fixed position through the compression of the limit spring 922 and the guidance of the limit frame 923 when inserted into the frame seat 91. Once the target plate is in place, the restoring force of the limit spring 922 will press the limit frame 923 tightly against the target plate, thereby achieving firm fixation of the target plate.

[0043] The implementation principle of a target plate drying device for liquid chromatography in the embodiment of the present application is as follows: by setting a drying mechanism to cooperate with a rotating mechanism 8, the device can be used to start the hot air blower 52 to blow hot air into the inside of the chassis 4 during use. The hot air acts on the outer surface of the target plate, which can achieve a good drying effect. In the drying process, the first motor 83 can be started to rotate forward and reverse to reciprocate. At this time, the first screw rod 84 can be driven to reciprocate inside the guide rail 82. The rotation of the first screw rod 84 can drive the slider 85 inside the guide rail 82 to slide inside the guide rail 82. Since the screw rod rotates back and forth, the slider 85 can be driven to slide back and forth inside the guide rail 82. During the sliding of the slider 85, the linkage rod 864 at the outer end of the hinge seat 862 is pushed. The outer end of the linkage rod 864 is hinged to the back of the rotating wheel 863. At this time, the linkage rod 864 pushes the two sets of rotating wheels 863 and the slider 85 slides back and forth, so that the two sets of rotating wheels 863 can be driven to rotate synchronously. The rotation of the two sets of rotating wheels 863 can drive the positioning mechanism 9 to be in a rotating state. By driving the positioning mechanism 9 to rotate, the target plate inside it can be driven to rotate, so that the target plate can evenly contact the outer shell to dry the hot air, and the centrifugal force generated during its rotation can also throw out the excess water. It can be seen that, on the one hand, the device can increase its contact area with the drying hot air and improve its overall drying uniformity. On the other hand, the rotary design can throw out the water by the centrifugal force, so as to improve its overall drying efficiency. In addition, the overall drying is more uniform during the drying process, which further improves the overall drying efficiency of the device.

[0044] By setting the displacement mechanism 7 and the driving mechanism 6, the device can be operated by starting the second motor 63 during use, and the second motor 63 is used to drive the worm 65 inside the fixed plate 61 to rotate. The rotation of the worm 65 can drive the worm wheel 62 to rotate, and the worm 65 is connected to each other by the connecting shaft 64, so that the two groups of worm wheels 62 and the worm 65 can be synchronously driven to be in a rotating state, and the two groups of worm wheels 62 can be synchronously driven to synchronously drive the second screw rod 72 inside the side rail 71 to rotate. The rotation of the second screw rod 72 can assist in driving the sliding rod 73 inside the side rail 71 to slide. The sliding rod 73 displaces the side rail 71 to slide back and forth inside, so that the device can automatically adjust the positioning mechanism 9 to extend and retract from the inside of the chassis 4, so that the device can automatically adjust the position of the target plate, and the overall drying efficiency of the device can be improved.

[0045] By setting the positioning mechanism 9, during the use of the device, the push plate 924 is first moved by toggling, and the limit spring 922 inside the outer rail 921 can be pushed to contract by the push plate 924. The contraction of the limit spring 922 can cause the limit frame 923 to interactively move toward both sides, and the inner side of the limit frame 923 is stretched open. At this time, the target plate body 2 can be placed inside the frame seat 91, and the push plate 924 is released. The limit spring 922 loses its limit and resets. The limit spring 922 resets to push the limit frame 923 to slide inwardly. The limit frame 923 slides inwardly, and at this time, the limit frame 923 can fit on both sides of the target plate body 2. The two sides of the body 2 are fitted and connected, which can stably clamp and position the target plate body 2, so that the target plate body 2 can be stably located on the inner side of the frame seat 91. When the rotating mechanism 8 drives the frame seat 91 to rotate, it can assist in pushing the target plate body 2 inside the frame seat 91 to rotate. The rotation of the target plate body 2 can assist in quickly drying the target plate body 2, and the inner side of the frame seat 91 adopts a spring limit design, which can have a certain buffering function, convenient for clamping target plates of different sizes, and at the same time have a certain buffering effect, which can improve its overall stability, avoid damage to the target plate, and improve its drying effect. The setting of the air vent 93 can assist in air conduction and ventilation, and can improve its overall ventilation and drying effect.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
