Description

Technical Field

[0001] This application relates to the technical field of steam sterilization, and particularly to a steam sterilization device for oral liquid bottle gaskets. Background Art

[0002] During the production of medicinal oral liquid bottles, a gasket is installed at the mouth of the oral liquid bottle or on the bottle cap. The gasket can isolate the oral liquid from the bottle cap, prevent the leakage of the oral liquid, play a sealing role, thereby protecting the oral liquid from contamination and oxidation, and extending the shelf life of the oral liquid. At the same time, the gasket can prevent the direct contact between the oral liquid and the bottle cap, avoiding the chemical reaction between the substances in the bottle cap and the oral liquid, thereby protecting the quality of the drug.

[0003] Before the gasket is installed, it needs to be sterilized. Currently, the conventional sterilization method is steam sterilization. Since the temperature of the steam is much higher than the tolerance temperature of general bacteria, it can quickly denature the proteins in the bacteria, resulting in the destruction of the cell structure and the disorder of metabolism, making them lose their viability, thereby achieving the sterilization effect. High temperature can also inhibit the reproduction of bacteria and reduce their viability. At the same time, the high humidity of the steam can increase the wetness of the bacterial surface, making the bacteria more vulnerable to the influence of high temperature.

[0004] Since the number of gaskets to be sterilized is large, the gaskets will pile up together during sterilization, making the steam unable to fully sterilize the piled-up gaskets, thus affecting the final sterilization effect and efficiency of the gaskets. Summary of the Invention

[0008] Optionally, two air supply pipes are provided on the top of the sterilization cylinder, each of which is connected to the air inlet channel, and the two air supply pipes are respectively used to connect to external steam equipment and dry hot air equipment to provide steam and dry hot air to the sterilization cylinder respectively.

[0009] Optionally, each of the through holes includes a first acceleration hole and a second acceleration hole from bottom to top, and a plate is placed In A sealing member is movably provided between the first acceleration hole and the second acceleration hole. When the placement plate moves upward, the sealing member moves to prevent the first acceleration hole from being connected to the second acceleration hole; when the placement plate moves downward, the sealing member moves to connect the first acceleration hole and the second acceleration hole.

[0010] Optionally, each of the through holes also includes a connecting channel connecting the first acceleration hole and the second acceleration hole, the seal is vertically slidably connected in the connecting channel, a return member is provided on the top of the seal, the top of the return member is connected to the inner wall of the placement plate, and the bottom end is connected to the top surface of the seal, the seal closes the first acceleration hole when it moves downward, and opens the first acceleration hole when it moves upward.

[0011] Optionally, the first acceleration hole and the second acceleration hole are both configured to be tapered with a diameter gradually decreasing from bottom to top.

[0012] Optionally, a toggle piece is slidably disposed on the top surface of the placement plate. The toggle piece is horizontal and disposed along the radial direction of the placement plate. The toggle piece is slidably connected to the central axis through a connecting rod. The toggle piece is always in close contact with the top surface of the placement plate to continuously flip the gasket.

[0013] Optionally, one end of the connecting rod is hinged to the toggle piece, and the other end is slidably connected to the central axis through a sleeve. The connecting rod is hinged to the sleeve, and a torsion spring is provided at the end where the connecting rod is hinged to the sleeve. One end of the torsion spring is connected to the connecting rod, and the other end is connected to the sleeve. The torsion spring is used to keep the connecting rod close to the central axis, and the length of the toggle piece is smaller than the radius of the placement plate.

[0014] In summary, the present application includes at least one of the following beneficial effects: 1. By arranging multiple layers of placement trays in the sterilization cylinder, a larger number of gaskets can be sterilized at one time, and a certain number of gaskets can be placed on each layer of placement trays, so that the gaskets to be sterilized in each layer are not piled up together, and steam can easily penetrate the gasket layer. A toggle piece is slidably arranged on the top surface of each placement tray, and the length of the toggle piece is less than the diameter length of the placement tray. The toggle piece is connected to the central axis through a connecting rod, one end of the connecting rod is hinged to the toggle piece, and the other end is slidably connected to the central axis through a sleeve. The connecting rod is hinged to the sleeve, and a torsion spring is arranged at one end of the connecting rod and the sleeve. The torsion spring is used to keep the connecting rod close to the central axis, so that the connecting rod does not rotate with the central axis, but only opens or closes along the radial direction of the placement tray. When the placement tray rotates with the central axis, the guide block at the bottom of the placement tray moves to the interference block on the sealing tray. When the cam is in motion, the guide block will slide upward along the surface of the interference block, and the guide block will drive the placement plate to move upward. Similarly, when the guide block slides downward along the surface of the interference block, the guide block will drive the placement plate to move downward synchronously. When the placement plate moves upward, the placement plate drives the toggle member to move upward. At this time, the angle between the connecting rod and the central axis increases, and the toggle member moves toward the edge of the placement plate along the radial direction of the placement plate, so that the toggle member toggles and turns over the gasket at the edge of the placement plate; when the placement plate moves downward, the toggle member follows the downward movement, and the angle between the connecting rod and the central axis decreases. The toggle member moves toward the inner circle direction of the center of the placement plate, thereby toggling and turning over the gasket in the inner circle area of ​​the placement plate. The toggle member is continuous during the entire movement process, and can turn over the gasket on the inner circle to the edge, or turn over the gasket on the edge to the inner circle, so as to fully stir the gasket so that the gasket surface is fully in contact with the high-temperature steam. 2. A first accelerating hole and a second accelerating hole are provided on the placement plate, and a sealing member is movably provided between the first accelerating hole and the second accelerating hole, and the top of the sealing member is connected to the inner wall of the placement plate through a restoring member. When the placement plate moves upward, the volume of the closed space between the placement plate and the sealing plate above it decreases, while the volume of the cavity below the placement plate increases, so that the pressure of the cavity above the placement plate is greater than the pressure of the cavity below the placement plate. Therefore, under the action of the pressure and the restoring force generated by the restoring member, the sealing member moves downward to block the first accelerating hole, and at the same time, the air inlet is opened, and steam is sucked into the cavity below the placement plate from the air inlet; when the placement plate moves downward, the volume of the cavity above the placement plate increases. The volume of the lower cavity decreases, and the air inlet is closed and the air outlet is opened, so that the pressure in the cavity below the placement plate increases. The sealing member moves upward under the pressure to connect the first acceleration hole, so that the steam sucked into the cavity below the placement plate can be ejected upward through the first acceleration hole and the second acceleration hole after being pressurized. The pressurized steam is ejected from the second acceleration hole at an accelerated speed, so that the steam can be sprayed on the surface of the gasket more evenly. The speed of the ejected steam can be further controlled by increasing or decreasing the diameter of the acceleration hole. The ejected steam can be used to effectively impact the gasket, so that the gasket can turn over or roll under the impact of the steam, so that the steam spraying is more even.

[0017] The following further describes this application in detail with reference to the Figures 1-6 accompanying drawings.

[0018] An embodiment of this application discloses a steam sterilization device for oral liquid bottle gaskets. Referring to Figures 1 to 3 , the steam sterilization device for oral liquid bottle gaskets includes a sterilization cylinder 1. Legs 11 are fixed to the bottom of the sterilization cylinder 1, and the sterilization cylinder 1 can be stably placed on the ground through the legs 11. An air supply pipe 12 is fixed to the top of the sterilization cylinder 1. There are two air supply pipes 12, and both are connected to the internal space of the sterilization cylinder 1. The two air supply pipes 12 can be respectively externally connected to a steam device and a dry hot air device. Among them, the steam device can provide high-temperature steam for sterilization to the sterilization cylinder 1, which can be a device such as an electric heating high-temperature steam generator, and the dry hot air device can provide dry hot air flow to the sterilization cylinder 1, which can be a hot air blower or other devices. After sterilizing the gasket, the steam device can be closed. At this time, the dry hot air device passes dry hot air flow into the sterilization cylinder 1, and the dry hot air flow can dry the gasket after steam sterilization, thereby reducing subsequent processing steps of the gasket and improving the production efficiency of the gasket. In order to facilitate the switching between steam and dry hot air flow, solenoid valves can be respectively installed on the two air supply pipes 12, and the air supply switching of the two air supply pipes 12 can be automatically controlled through an external control unit.

[0019] A feed inlet 13 is opened on the side wall of the sterilization cylinder 1, and a sealing door 14 is hinged to the position of the sterilization cylinder 1 corresponding to the feed inlet 13. The gasket to be sterilized can be put into the interior of the sterilization cylinder 1 from the feed inlet 13. After the sealing door 14 is closed, it can block the feed inlet 13, so that the interior of the sterilization cylinder 1 remains in a sealed state. The sterilization cylinder 1 includes an outer cylinder 15 and an inner cylinder 16 arranged coaxially. The inner diameter of the outer cylinder 15 is greater than the outer diameter of the inner cylinder 16, so that an air inlet channel 17 is left between the outer cylinder 15 and the inner cylinder 16 for externally connecting to a gas supply device. Specifically, the feed inlet 13 is opened at the corresponding positions of the outer cylinder 15 and the inner cylinder 16 at the same time, so that the gasket can pass through the outer cylinder 15 and the inner cylinder 16 and be put into the interior of the inner cylinder 16. The sealing door 14 is hinged to the side wall of the outer cylinder 15 through a hinge, and a sealing strip is embedded in the inner side wall of the sealing door 14, so that the sealing door 14 can form a good sealing effect with the outer cylinder 15 after being closed.

[0020] Specifically, the air supply pipe 12 is fixed to the top wall of the outer cylinder 15, and the air supply pipe 12 is connected to the air inlet channel 17, so that the external air supply equipment can provide high-temperature steam or dry hot air flow to the air inlet channel 17 through the air supply pipe 12. Correspondingly, a drain pipe 18 is fixed to the bottom of the outer cylinder 15, and the drain pipe 18 is also connected to the air inlet channel 17, so that the water after the steam condenses can be discharged from the drain pipe 18. A solenoid valve can be fixed to the drain pipe 18, and the solenoid valves on the drain pipe 18 and the air supply pipe 12 can be directly controlled by an external control unit and PLC control logic, so as to facilitate the control of the air intake and drainage actions. The specific PLC control logic is relatively common and common, as long as the functions of air supply and drainage can be achieved, it will not be repeated here.

[0021] The sterilization cylinder 1 is coaxially penetrated and rotatably connected with a central axis 2 from bottom to top. The bottom of the central axis 2 passes through the outer cylinder 15, and the top is rotatably connected to the top wall of the inner cylinder 16. A driving member 21 is arranged on the top of the central axis 2. The driving member 21 can be a small servo motor. The output shaft of the driving member 21 is coaxially fixed with the central axis 2, and the driving member 21 is fixed to the top of the outer cylinder 15. The driving member 21 can drive the central axis 2 to rotate along the vertical axis.

[0022] Reference Figures 2 to 4 , a plurality of placement disks 3 and sealing disks 4 are coaxially arranged inside the inner cylinder 16, and the circumferential sides of the placement disks 3 and the sealing disks 4 are sealed and connected to the inner wall of the inner cylinder 16 through sealing rubber rings, and the sealing disks 4 are correspondingly arranged on the upper and lower sides of each placement disk 3. Specifically, in the embodiment of the present application, three placement disks 3 are preferably arranged, and the three placement disks 3 are arranged at intervals along the length direction of the central axis 2, each placement disk 3 is arranged coaxially with the central axis 2, and a limiting plate (not shown) is fixed on the side wall of the central axis 2 corresponding to the position of each placement disk 3, the limiting plates are arranged at intervals in the circumferential direction on the side wall of the central axis 2, and are arranged in a divergent shape along the axis of the central axis 2, the limiting plates are inserted into the inner side wall of the corresponding placement disk 3, and the limiting plates are vertically slidably connected to the placement disk 3, so that each placement disk 3 can rotate synchronously with the central axis 2 and can also slide along the axial direction of the central axis 2. The top surface of the placement tray 3 is used to place the gaskets to be sterilized. Multiple placement trays 3 are used to place gaskets, so that the sterilization cylinder 1 can sterilize a large number of gaskets at a time. At the same time, more gaskets can be distributed on each layer of the placement tray 3, so that the gaskets to be sterilized in each layer are not piled up together, which makes it easier for subsequent steam to penetrate the gasket layer, effectively improving the effect of steam sterilization. In other embodiments of the present application, the number of placement trays 3 can be increased or decreased according to the actual height of the sterilization cylinder 1, so that the placement trays 3 can accommodate a sufficient number of gaskets.

[0023] Further, see Figures 3 to 5, the placement tray 3 is slidably connected to the inner cylinder 16, while the position of the sealing tray 4 in the inner cylinder 16 remains fixed, and the sealing tray 4 is rotatably connected to the central shaft 2. Since both the placement tray 3 and the sealing tray 4 are hermetically connected to the inner wall of the inner cylinder 16, two independent sealed cavities are formed between the placement tray 3 and the two sealing trays 4 on its corresponding upper and lower sides. The sealed cavity between each placement tray 3 and the sealing tray 4 on its upper side is defined as the first cavity 5. Similarly, the sealed cavity between each placement tray 3 and the sealing tray 4 on its lower side is defined as the second cavity 6. Therefore, the first cavity 5 and the second cavity 6 are correspondingly provided on both the upper and lower sides of each placement tray 3, and the gaskets on each placement tray 3 are placed in the first cavity 5.

[0024] The placement tray 3 is provided with a plurality of through holes allowing steam to pass through, so that steam can enter the first cavity 5 from the second cavity 6 corresponding to each placement tray 3 through the through holes, thereby sterilizing the gasket from bottom to top. To enable the steam to circulate in the first cavity 5 and the second cavity 6 corresponding to each placement tray 3, air inlets 161 and air outlets 162 are provided on the cylinder wall of the inner cylinder 16 corresponding to each placement tray 3. Specifically, each air inlet 161 is opened on the side wall of the second cavity 6 below each placement tray 3 of the inner cylinder 16, and each air outlet 162 is opened on the side wall of the first cavity 5 above each placement tray 3 of the inner cylinder 16, and the positions where the air inlet 161 and the air outlet 162 are opened correspond to each other. The air inlet 161 communicates the air inlet passage 17 with the second cavity 6, and the air outlet 162 communicates the air inlet passage 17 with the first cavity 5, so that the steam in the air inlet passage 17 can enter the second cavity 6 through the air inlet 161, then enter the first cavity 5 upward from the second cavity 6 through the through holes to sterilize the gasket on the placement tray 3, and finally the steam re-enters the air inlet passage 17 through the air outlet 162, thereby realizing the circulation of steam in the sterilization cylinder 1.

[0025] The placement tray 3 can slide vertically up and down along the central shaft 2 inside the inner cylinder 16. At the same time, a closing plate 163 is provided on the circumferential side of the placement tray 3. One end of the closing plate 163 away from the placement tray 3 is slidably connected to the side wall of the inner cylinder 16 vertically, and a sliding groove is provided at one end of the closing plate 163 close to the placement tray 3. The edge side wall of the placement tray 3 is correspondingly slidably connected to the sliding groove of the closing plate 163, so that the placement tray 3 can rotate relative to the closing plate 163, and the closing plate 163 can also move up and down following the placement tray 3. When the closing plate 163 moves upward, it will gradually conduct the air inlet 161 and gradually close the air outlet 162, so that steam can enter the second cavity 6 through the opened air inlet 161 when the placement tray 3 moves upward; similarly, when the closing plate 163 moves downward, it will gradually close the air inlet 161 and gradually conduct the air outlet 162, so that steam can re-enter the air inlet passage 17 through the opened air outlet 162 when the placement tray 3 moves downward.

[0026] Furthermore, to enable the placement tray 3 to reciprocate vertically while rotating, a guide block 31 is fixed to the bottom surface of the placement tray 3. In the embodiment of the present application, there are two guide blocks 31, and the two guide blocks 31 are symmetrically distributed along the axis of the central shaft 2 and are located at the edge position of the placement tray 3. Correspondingly, two interference blocks 41 are fixed to the top surface of the sealing tray 4 located below the placement tray 3. The two interference blocks 41 are symmetrically distributed along the axis of the central shaft 2, and both of the two interference blocks 41 are correspondingly located on the rotation path of the guide block 31. The guide block 31 slides along the surface of the interference block 41 and the top surface of the sealing tray 4 corresponding to the lower part of the placement tray 3. In other embodiments of the present application, the number of the guide blocks 31 and the interference blocks 41 can be increased or decreased according to the actual size of the placement tray 3. It should be noted that the guide blocks 31 and the interference blocks 41 need to be set in pairs, that is, at least one pair of the guide blocks 31 and the interference blocks 41 are provided, and each pair of the guide blocks 31 or the interference blocks 41 are symmetrically distributed along the axis of the central shaft 2. In this way, when the guide block 31 rotates following the placement tray 3, the two guide blocks 31 will simultaneously contact one interference block 41 respectively. The outer surfaces of the interference block 41 and the guide block 31 are both arc surfaces with smooth transitions, so that the guide block 31 will move up or down along the smooth surface of the interference block 41 when passing through the interference block 41. During this process, the placement tray 3 will rise or fall accordingly, thereby realizing the periodic lifting movement of the placement tray 3 while rotating.

[0027] Furthermore, referring to Figure 3 and Figure 6 , to enable the steam to accelerate upward and effectively impact and flip the gasket when entering the first cavity 5 from the second cavity 6. Each through hole on the placement tray 3 sequentially includes a first acceleration hole 32, a communication channel 33, and a second acceleration hole 34 from bottom to top. The communication channel 33 connects the first acceleration hole 32 and the second acceleration hole 34. The first acceleration hole 32, the communication channel 33, and the second acceleration hole 34 are connected end to end to penetrate the placement tray 3. In the embodiment of the present application, one first acceleration hole 32 corresponds to two second acceleration holes 34, and both the first acceleration hole 32 and the second acceleration hole 34 are configured as tapered holes with a gradually decreasing diameter from bottom to top. When the steam passes through the first acceleration hole 32 and the second acceleration hole 34 sequentially from bottom to top, it can be accelerated continuously twice, so that the steam obtains sufficient kinetic energy when finally ejected from the second acceleration hole 34.

[0028] Further, a seal 35 is vertically slidably arranged in the communication channel 33 of the placement tray 3. The seal 35 can be made of sealing rubber material. When the seal 35 slides up and down, it can block or conduct the first acceleration hole 32. A part of the top end of the seal 35 protruding upward is slidably connected to the placement tray 3, and a restoring member 36 is arranged above the seal 35. The restoring member 36 can be a compression spring. The top end of the restoring member 36 is fixedly connected to the inner wall of the placement tray 3, and at the same time, the bottom end is fixedly connected to the top surface of the seal 35. In the initial state, the seal 35 blocks the first acceleration hole 32.

[0029] When the placement tray 3 moves upward, the volume of the first cavity 5 above the placement tray 3 decreases, while the volume of the second cavity 6 below the placement tray 3 increases, so that the pressure in the cavity above the placement tray 3 is greater than the pressure in the cavity below the placement tray 3. Therefore, under the action of the pressure and the restoring force generated by the restoring member 36, the seal 35 moves downward to block the first acceleration hole 32. At the same time, the closing plate 163 moves upward, so that the air inlet 161 gradually opens and the air outlet 162 gradually closes. At this time, steam is inhaled from the air inlet 161 into the second cavity 6 below the corresponding placement tray 3; when the placement tray 3 moves downward, the volume of the first cavity 5 above the placement tray 3 increases and the volume of the second cavity 6 below decreases, so that the pressure in the second cavity 6 below the placement tray 3 gradually becomes greater than the pressure in the first cavity 5. At the same time, the closing plate 163 moves downward, so that the air inlet 161 gradually closes and the air outlet 162 gradually opens. The seal 35 moves upward under the action of the pressure to conduct the first acceleration hole 32, so that the steam inhaled into the second cavity 6 below the placement tray 3 can continuously move upward through the first acceleration hole 32, the communication channel 33 and the second acceleration hole 34 after being pressurized. Finally, the pressurized steam is ejected from the second acceleration hole 34 at an accelerated speed, so that the steam can be sprayed on the gasket surface more fully. Moreover, the kinetic energy of the steam ejected after being pressurized is relatively large, and the ejected steam can also be used to effectively impact the gasket, so that the gasket can be turned over or rolled under the impact of the steam, so that the gasket can obtain more sufficient spraying of the steam.

[0030] Further, referring to Figure 5 and Figure 6, To further enhance the flipping effect of the stacked gaskets, two toggling members 37 are slidably arranged on the top surface of each placement plate 3. The toggling members 37 are horizontal and arranged along the radial direction of the placement plate 3. The two toggling members 37 are symmetrically distributed relative to the central axis 2. At the same time, a sleeve 7 is coaxially sleeved on the peripheral wall of the central axis 2 above the first cavity 5 corresponding to each placement plate 3. The position of the sleeve 7 relative to the central axis 2 remains fixed, which can be achieved by fixing it to the inner wall of the inner cylinder 16 through a fixing rod. And the sleeve 7 is slidably connected to the central axis 2. The toggling member 37 is connected to the sleeve 7 through a connecting rod 71. Both ends of the connecting rod 71 are hinged to the toggling member 37 and the sleeve 7 respectively. When the placement plate 3 rotates, the toggling member 37 does not rotate along with it, but only moves up and down during the lifting and lowering process of the placement plate 3. One end of the connecting rod 71 hinged to the sleeve 7 is provided with a torsion spring 72. One end of the torsion spring 72 is fixedly connected to the connecting rod 71, and the other end is fixedly connected to the sleeve 7. The torsion spring 72 can keep the end of the connecting rod 71 away from the central axis 2 always approaching the central axis 2, so that the toggling member 37 always closely adheres to the top surface of the placement plate 3.

[0031] To improve the flipping effect of the toggling member 37 on the gasket, the length of the toggling member 37 is less than the radius length of the placement plate 3, and along the rotation direction of the placement plate 3, the thickness of the toggling member 37 gradually increases, so that the surface of the toggling member 37 in contact with the gasket can contact the gasket at a certain inclination angle, making it easier to shovel up and flip the gasket. At the same time, a flipping piece is fixed on the surface of the toggling member 37 in contact with the gasket. The flipping piece can be made of soft silicone material, so that the flipping piece can deform itself when toggling the gasket, enhancing the flipping effect on the gasket while reducing the wear on the surface of the gasket.

[0032] When the placement plate 3 rotates following the central axis 2, it will periodically lift and lower. When the placement plate 3 moves upward, the placement plate 3 pushes the toggling member 37 upward. At this time, the angle between the connecting rod 71 and the central axis 2 increases, and the toggling member 37 will move along the radial direction of the placement plate 3 towards the edge of the placement plate 3. At this time, the toggling member 37 gradually moves from the inner circle position of the placement plate 3 to the edge of the placement plate 3. During this process, the gasket can be gradually toggled and turned over from the inside to the outside; when the placement plate 3 moves downward, the toggling member 37 follows and moves downward. At this time, the angle between the connecting rod 71 and the central axis 2 decreases, and the toggling member 37 moves towards the inner circle direction of the placement plate 3, thereby gradually toggling and turning over the gasket from the outside to the inside. Since the toggling member 37 is continuous during the entire movement process, the gasket originally located in the inner circle can be flipped to the edge position of the placement plate 3 during the movement of the toggling member 37, or the gasket at the edge position of the placement plate 3 can be flipped to the inner circle, fully stirring the gasket and making the surface of the gasket fully contact with the high-temperature steam.

[0033] The implementation principle of a steam sterilization device for an oral liquid bottle gasket in an embodiment of this application is as follows: The placement tray 3 rotates following the central shaft 2. When the placement tray 3 rotates, the guiding block 31 slides along the surfaces of the placement tray 3 and the interference block 41, enabling the placement tray 3 to perform periodic lifting and lowering movements. When the placement tray 3 moves upward, the seal 35 moves downward to block the first acceleration hole 32, and at the same time, the air inlet 161 gradually opens while the air outlet 162 gradually closes. At this time, steam is inhaled from the air inlet 161 into the second cavity 6 below the corresponding placement tray 3. When the placement tray 3 moves downward, the closing plate 163 moves downward, causing the air inlet 161 to gradually close and the air outlet 162 to gradually open. The seal 35 moves upward under the action of pressure to conduct the first acceleration hole 32, so that the steam inhaled into the second cavity 6 below the placement tray 3 is finally accelerated and ejected from the second acceleration hole 34 after pressurization, enabling the steam to be sprayed more fully on the surface of the gasket. Moreover, the kinetic energy of the steam ejected after pressurization is relatively large, and the ejected steam can also be used to effectively impact the gasket, causing the gasket to turn over or roll under the impact of the steam, so that the gasket can be sprayed more fully with steam.

[0034] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
