Description

Technical Field

[0001] This invention belongs to the field of bottle cap padding technology, and particularly relates to a bottle cap padding device for headspace injection bottles. Background Technology

[0002] Headspace vials are high-performance, low-cost sample processing devices specifically designed for sample preparation in chromatographic analysis. They are primarily used in the injection process of gas chromatography or GC-MS, and are particularly suitable for the qualitative and quantitative analysis of volatile components in liquid or solid samples. A cap gasket is typically required inside the headspace vial cap, necessitating the use of a cap gasket device.

[0003] Chinese patent disclosure (CN106112468A) discloses an automatic bottle cap padding device, which includes a conveyor line for conveying bottle caps. Several storage racks are arranged side-by-side on one side of the conveyor line, each containing vertically stacked pads. A pad pusher plate is mounted on the conveyor line, connected to a drive cylinder, and has several first positioning arc grooves arranged side-by-side on its inner side. A bottle cap pusher plate is mounted on the other side of the conveyor line, connected to the drive cylinder, and has several second positioning arc grooves arranged side-by-side on its inner side. A pressing mechanism for pressing the pads into the bottle caps is located above the conveyor line. This automatic bottle cap padding device can automatically pad bottle caps, is simple in structure and easy to implement, has high padding efficiency, and provides accurate positioning during padding, significantly reducing the defect rate. While current gasket-adding devices can also install gaskets on bottle caps, they simply press the gasket into the bottle cap during installation. Although this method can install the gasket, residual air remains in the contact area between the gasket and the bottle cap, failing to guarantee a complete fit between the gasket and the bottle cap. Consequently, the actual installation effect of the gasket cannot be guaranteed. Furthermore, the cleaning effect inside the bottle cap cannot be guaranteed before gasket installation, resulting in poor practical application performance. To solve this problem, there is an urgent need for a bottle cap gasket-adding device for headspace sampling bottles. Summary of the Invention

[0004] The purpose of this invention is to address the problems of current gasket installation devices, which, while capable of installing gaskets on bottle caps, merely press the gasket into the bottle cap. This method achieves gasket installation, but residual air remains in the contact area between the gasket and the bottle cap, failing to guarantee a complete fit and thus compromising the actual installation effect. Furthermore, the cleanliness of the bottle cap before gasket installation cannot be guaranteed, resulting in poor practical application. Therefore, this invention proposes a gasket installation device for headspace sampling bottles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bottle cap padding device for headspace injection vials, comprising a machine base, a controller fixedly installed on one outer wall of the machine base, a frame fixedly installed on the top surface of the machine base, a door installed on the outer side of the machine base via hinges, a movable groove provided on the top surface of the machine base such that the frame is positioned above the movable groove, a drive motor fixedly installed on one outer wall of the machine base, a drive stud fixedly installed at one end of the output shaft of the drive motor, a bottle cap storage mechanism movably installed outside the drive stud, and synchronously realizing the movement of the storage mechanism along the extension direction of the drive stud, such that the extension direction of the drive stud corresponds to the extension direction of the movable groove, the bottle cap storage mechanism is used for stable storage of bottle caps, and a padding mechanism is provided on the frame for continuous padding of bottle caps.

[0006] By adopting the above technical solution and by providing a bottle cap storage mechanism and a padding mechanism, this design not only enables the automatic installation of the pads, but also achieves automatic positioning of the bottle caps during the pad pressing process. The positioning effect is directly proportional to the downward pressure, and even under high downward pressure, the bottle caps will not be misaligned, greatly improving the processing accuracy of the equipment and enhancing its application effect.

[0011] As a further description of the above technical solution: The storage tray has multiple bottle cap storage slots inside, which are open upwards and arranged in a ring shape. Each of the multiple bottle cap storage slots is equipped with a bottle cap clamping and positioning component. The bottle cap clamping and positioning component includes a horizontal spring sleeve shaft and a vertical spring sleeve shaft. The horizontal spring sleeve shaft is radially distributed outward with the center of the vertical spring sleeve shaft as the axis. The outer side of the horizontal spring sleeve shaft is slidably mounted on the bottom of the moving block along the axial direction. At the same time, the moving block is arranged in a vertical direction.

[0012] As a further description of the above technical solution: A positioning clip is fixedly installed at the top of the movable block. The movable block is slidably connected to the side sliding groove provided on the top surface of the bottle cap storage slot. The longitudinal spring sleeve shaft is longitudinally fixedly installed in the central hole provided on the top surface of the bottle cap storage slot. A pressure bearing shaft is slidably installed on the outside of the longitudinal spring sleeve shaft. The pressure bearing shaft is connected to the movable block by a connecting belt. One end of the vent pipe passes through and extends to the inside of the bottle cap storage slot. The top end of the pressure bearing shaft is located outside the central hole.

[0013] As a further description of the above technical solution: The padding mechanism includes an electrically controlled push rod, which is fixedly installed on the top surface of the frame. One end of the output shaft of the electrically controlled push rod is fixedly installed with a mounting plate. A bottom shell is fixedly installed on the bottom surface of the mounting plate. Bottle pad storage boxes are fixedly installed at both ends of the bottom shell. A side-push cylinder is provided on the side wall of the bottle pad storage box. An internal hole is provided inside the bottom shell. A padding pressing component is provided inside the internal hole. A pad feeding groove is provided between the bottle pad storage box and the internal hole. A supporting soft pad is provided inside the internal hole.

[0014] As a further description of the above technical solution: The padding and pressing assembly includes a pressing cylinder, which is fixedly installed inside the built-in hole. A pressing shell is fixedly installed at one end of the output shaft of the pressing cylinder. An internal motor is fixedly installed on the top surface of the pressing shell.

[0015] As a further description of the above technical solution: The inner side of the pressing shell is provided with an inner rotating groove, and a rotating cylinder with a rotating ring is rotatably installed on the inner side of the inner rotating groove. The drive toothed roller and the toothed groove provided on the inner surface of the rotating cylinder mesh with each other for transmission. Several pressing convex balls are rotatably arranged on the bottom surface of the rotating cylinder. The pressing convex balls are spheres with a diameter of 12mm. The several pressing convex balls are used to remove air between the contact area between the gasket and the bottle cap, further improving the installation firmness of the gasket.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a bottle cap storage mechanism and a padding mechanism are provided. During processing, the headspace sample bottle caps requiring padding are placed inside multiple bottle cap storage slots. After installation, the drive motor is turned on, driving the drive stud to rotate. The drive stud drives the bottle cap storage mechanism to move, positioning the bottle cap storage slot directly below the pressing shell. At this time, the side-push cylinder is activated, pushing the bottle pad stored in the padding storage box to move laterally and being pushed into the support pad inside the built-in hole through the padding delivery slot. At this time, the pressing cylinder is activated, pushing the pressing shell downwards. The pressing shell and the rotating cylinder drive the pad downwards, allowing the rotating cylinder to enter the bottle cap storage slot. The gasket is pressed into the bottle cap through a groove. At this time, the bottle cap is subjected to greater pressure, which can press down the bearing shaft. The downward movement of the bearing shaft pulls the positioning clips inward through various connecting belts. Each positioning clip can automatically position the bottle cap during the gasket installation process. Through this design, not only can the gasket be automatically installed, but the bottle cap can also be automatically positioned during the gasket pressing process. Moreover, the positioning effect is directly proportional to the downward pressure. Even under high downward pressure, it will not cause the bottle cap to shift, which greatly improves the processing accuracy of the equipment and enhances the application effect of the equipment.

[0017] 2. In this invention, a rotatable rotating cylinder is provided within the padding and pressing assembly, and several pressing protrusions are provided on the bottom surface of the rotating cylinder. After the pad is pressed into the bottle cap, the built-in motor can be automatically turned on, driving the drive toothed roller to rotate. The drive toothed roller can drive the rotating cylinder with toothed grooves to rotate, and the several pressing protrusions of the rotating cylinder can continuously roll on the surface of the pad. Since there are many contact points between the pressing protrusions and the pad, this process can effectively eliminate air between the contact area between the pad and the bottle cap, further improving the installation firmness of the pad. In addition, during this process, the bottle cap is still firmly positioned by each positioning clip, and the stability can be guaranteed.

[0018] 3. In this invention, by incorporating an airflow dust removal component within the bottle cap storage mechanism, after the bottle cap is installed, as the bottle cap storage mechanism moves to below the padding mechanism, the outer gear disc meshes with the built-in gear plate within the equipment, simultaneously driving multiple fan blades to rotate. These fan blades generate airflow within the air cylinder, which flows into the top plate. After being accelerated by two airflow speed-increasing worm gears within the top plate, the airflow is discharged through the outlet pipe into the bottle cap storage slot. This high-speed airflow, after acceleration, carries away some dust from inside the installed bottle cap. After the padding and pressing component completes the installation of the pad, the motor drives the storage plate to rotate, allowing the padding and pressing component to move above other bottle caps without pads and continue its work. This design enables automatic cleaning of accumulated dust inside the bottle cap during the process of moving to below the padding and pressing component after installation. The high airflow velocity provides a strong cleaning effect. Furthermore, this processing method allows for rapid batch processing of bottle caps, improving the overall efficiency of the equipment.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely 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 scope of protection of the present invention.

[0033] Please see Figures 1-11This invention provides a technical solution: a bottle cap padding device for headspace sampling bottles, comprising a machine base 5, a controller 1 fixedly installed on one outer wall of the machine base 5, a frame 3 fixedly installed on the top surface of the machine base 5, a door 6 installed on the outer side of the machine base 5 via a hinge, a movable groove 4 provided on the top surface of the machine base 5, a drive motor 8 fixedly installed on one outer wall of the machine base 5, a drive stud 9 fixedly installed at one end of the output shaft of the drive motor 8, a bottle cap storage mechanism 7 movably installed outside the drive stud 9, the bottle cap storage mechanism 7 being used for stable storage of bottle caps, and a padding mechanism 2 provided on the frame 3, the padding mechanism 2 being used for continuous addition of bottle cap pads.

[0034] The bottle cap storage mechanism 7 includes a slider 75, which is slidably mounted on a guide rail on the inner wall of the bottom surface of the machine base 5 via a bottom groove 73. The slider 75 is threaded onto the outside of the drive stud 9 via a threaded hole inside it. A control motor 72 is fixedly mounted on the top of the slider 75. A storage tray 71 is fixedly mounted on one end of the output shaft of the control motor 72. An internal toothed plate 10 is fixedly mounted on the bottom surface of the movable groove 4. A bottom hole is provided at the bottom of the storage tray 71, and an airflow dust removal component 74 is provided inside the bottom hole.

[0035] The storage tray 71 has multiple bottle cap storage slots 76 inside, and each of the multiple bottle cap storage slots 76 has a bottle cap clamping and positioning component 77 inside. The bottle cap clamping and positioning component 77 includes a transverse spring sleeve shaft 773 and a longitudinal spring sleeve shaft 775. The top surface of the bottle cap storage slot 76 has a central hole and a side sliding groove. The transverse spring sleeve shaft 773 is horizontally fixedly installed in the side sliding groove. A moving block 772 is slidably installed on the outside of the transverse spring sleeve shaft 773. A positioning clamping strip 771 is fixedly installed on the top of the moving block 772. The moving block 772 is slidably connected to the side sliding groove. The longitudinal spring sleeve shaft 775 is vertically fixedly installed in the central hole. A pressure bearing shaft 776 is slidably installed on the outside of the longitudinal spring sleeve shaft 775. The pressure bearing shaft 776 and the moving block 772 are connected by a connecting belt 774. One end of the vent pipe 747 passes through and extends to the inside of the bottle cap storage slot 76. The top of the pressure bearing shaft 776 is located outside the central hole.

[0036] In the above scheme, during processing, the headspace sample bottle caps that need to be padded are placed inside multiple bottle cap storage slots 76. After the installation is completed, the drive motor 8 is turned on, which drives the drive stud 9 to rotate. The drive stud 9 drives the bottle cap storage mechanism 7 to move, so that the bottle cap storage slot 76 is located directly below the pressing shell 242. At this time, the side push cylinder 26 is turned on, which pushes the bottle pads stored in the bottle pad storage box 23 to move to the side and pushes them into the support pads in the built-in hole through the pad delivery slot.

[0037] The padding mechanism 2 includes an electrically controlled push rod 21, which is fixedly installed on the top surface of the frame 3. One end of the output shaft of the electrically controlled push rod 21 is fixedly installed with a mounting plate 22. A bottom shell 25 is fixedly installed on the bottom surface of the mounting plate 22. Bottle pad storage boxes 23 are fixedly installed on both ends of the bottom shell 25. A side-push cylinder 26 is provided on the side wall of the bottle pad storage box 23. An internal hole is provided inside the bottom shell 25. A padding pressing component 24 is provided inside the internal hole. A padding groove is provided between the bottle pad storage box 23 and the internal hole. A supporting soft pad is provided inside the internal hole. The padding pressing component 24 includes a pressing cylinder 241, which is fixedly installed inside the internal hole. One end of the output shaft of the pressing cylinder 241 is fixedly installed with a pressing shell 242. An internal motor 243 is fixedly installed on the top surface of the pressing shell 242. A drive toothed roller 248 is fixedly installed on one end of the output shaft of the internal motor 243.

[0038] Furthermore, when the pressing cylinder 241 is activated, it can push the pressing shell 242 downward. The pressing shell 242 and the rotating cylinder 244 drive the gasket downward, so that the rotating cylinder 244 enters the bottle cap storage groove 76 and presses the gasket into the bottle cap. At this time, the bottle cap is subjected to greater pressure, which can press down the pressure bearing shaft 776. The downward-moving pressure bearing shaft 776 pulls each positioning clamp 771 inward through each connecting belt 774. Each positioning clamp 771 can realize the automatic positioning of the bottle cap during the gasket installation process.

[0039] The above design not only enables automatic installation of the gasket, but also achieves automatic positioning of the bottle cap during the gasket pressing process. The positioning effect is directly proportional to the downward pressure, and even under high downward pressure, the bottle cap will not be misaligned, greatly improving the processing accuracy of the equipment and enhancing its application effect.

[0040] The inner side of the pressing shell 242 is provided with an inner rotating groove 245. A rotating cylinder 244 with a rotating ring 246 is rotatably installed on the inner side of the inner rotating groove 245. The drive toothed roller 248 meshes with the toothed grooves provided on the inner surface of the rotating cylinder 244. Several pressing convex balls 247 are rotatably arranged on the bottom surface of the rotating cylinder 244. The pressing convex balls 247 are spheres with a diameter of 12mm. The several pressing convex balls 247 are used to remove air between the contact area between the gasket and the bottle cap, further improving the installation firmness of the gasket.

[0041] By adopting the above solution, after the gasket is pressed into the bottle cap, the built-in motor 243 can be automatically turned on, driving the drive toothed roller 248 to rotate. The drive toothed roller 248 can drive the rotating cylinder 244 with toothed grooves to rotate. Several pressing protrusions 247 of the rotating cylinder 244 can continuously roll on the surface of the gasket. Since there are many contact points between the pressing protrusions 247 and the gasket, this process can effectively eliminate the air between the gasket and the bottle cap's contact area, further improving the gasket's installation firmness. In addition, during this process, the bottle cap is still firmly positioned by each positioning clip 771, ensuring stability.

[0042] The airflow dust removal assembly 74 includes an air cylinder 742, which is fixedly installed in a bottom hole. A top plate 748 is fixedly installed at the top of the air cylinder 742. Air outlet pipes 747 are fixedly installed on both outer walls of the top plate 748. Two airflow speed-increasing worm gears 741 are fixedly installed inside the top plate 748. A bottom cover 746 is fixedly installed at the bottom of the air cylinder 742. An installation shaft 743 is rotatably installed on the inner side of the air cylinder 742 via a shaft bracket 749. Multiple fan blades 744 are fixedly installed on the outer side of the installation shaft 743. The multiple fan blades 744 are located on the inner side of the air cylinder 742. An outer gear plate 745 is fixedly installed at the bottom end of the installation shaft 743. The outer gear plate 745 is located on the outer side of the air cylinder 742. The outer gear plate 745 meshes with the inner gear plate 10 for transmission. Several airflow grooves are provided on the inner wall of the air cylinder 742.

[0043] In the above scheme, after the bottle cap is installed, during the process of the bottle cap storage mechanism 7 moving to the bottom of the padding mechanism 2, the outer gear plate 745 can mesh and rotate with the built-in gear plate 10 in the equipment, and at the same time drive multiple fan blades 744 to rotate. The multiple fan blades 744 can generate airflow in the air cylinder 742. This airflow can flow into the top plate 748. After being accelerated by the two airflow speed-increasing worm gears 741 in the top plate 748, it can be discharged into the bottle cap storage slot 76 through the air outlet pipe 747. This high-speed airflow after acceleration can carry away some dust in the bottle cap after installation. After the padding and pressing assembly 24 completes the installation of the pad, the motor 72 drives the storage plate 71 to rotate, so that the padding and pressing assembly 24 moves to the top of other bottle caps without pads and continues to work.

[0044] With the above design, the dust inside the bottle cap can be automatically cleaned during the process of moving it under the padding and pressing component 24 after the bottle cap is installed. The high gas flow rate provides a strong cleaning effect. At the same time, this processing method can quickly complete the batch processing of bottle caps and improve the overall working efficiency of the equipment.

[0045] Working principle: During processing, the headspace sample bottle caps requiring padding are placed inside multiple bottle cap storage slots 76. After installation, the drive motor 8 is turned on, driving the drive stud 9 to rotate. The drive stud 9 drives the bottle cap storage mechanism 7 to move, positioning the bottle cap storage slots 76 directly below the pressing shell 242. At this time, the side-push cylinder 26 is activated, pushing the bottle pads stored in the bottle pad storage box 23 to move laterally and push them into the support pads in the built-in holes through the pad delivery groove. At this time, the pressing cylinder 241 is activated. The pressing cylinder 241 can push the pressing shell 242 down, and the pressing shell 242 and the rotating cylinder 244 drive the gasket down, so that the rotating cylinder 244 enters the bottle cap storage groove 76 and presses the gasket into the bottle cap. At this time, the bottle cap is subjected to greater pressure, which can press down the pressure bearing shaft 776. The downward-moving pressure bearing shaft 776 pulls each positioning clamp 771 to move inward through each connecting belt 774. Each positioning clamp 771 can realize the automatic positioning of the bottle cap during the gasket installation process. After the gasket is pressed into the bottle cap, the built-in motor 243 can be automatically turned on, driving the drive toothed roller 248 to rotate. The drive toothed roller 248 can drive the rotating cylinder 244 with toothed grooves to rotate. Several pressing protrusions 247 of the rotating cylinder 244 can continuously roll on the surface of the gasket. Since there are many contact points between the pressing protrusions 247 and the gasket, this process can effectively remove the air between the gasket and the bottle cap, further improving the installation firmness of the gasket. During this process, the bottle cap is still firmly positioned by each positioning clip 771. After the bottle cap is installed, as the bottle cap storage mechanism 7 moves to below the padding mechanism 2, the outer gear plate 745 can mesh and rotate with the built-in gear plate 10 inside the equipment, simultaneously driving multiple fan blades 744 to rotate. The multiple fan blades 744 can generate airflow in the air cylinder 742. This airflow can flow into the top plate 748, and after being accelerated by the two airflow speed-increasing worm gears 741 in the top plate 748, it can be discharged into the bottle cap storage slot 76 through the air outlet pipe 747. This high-speed airflow after acceleration can carry away some dust inside the bottle cap after installation. After the padding and pressing assembly 24 completes the installation of the pad, the motor 72 drives the storage plate 71 to rotate, so that the padding and pressing assembly 24 moves to the top of other bottle caps without pads and continues the operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
