Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment parts technology, and in particular to a stopper device with a buffer platform. Background Technology
[0002] In industries such as pharmaceuticals, biotechnology, food and beverage, and chemicals, reliable container sealing is crucial for ensuring product quality, safety, and extending shelf life. Stoppering is one of the most common sealing methods. Traditional stoppering devices typically transfer force directly to the container when the stopper head presses down on the stopper. For glass bottles or certain plastic bottles, this rigid impact can easily cause the bottom or body of the container to crack, resulting in product loss and even the risk of contamination. Utility Model Content
[0003] In view of the shortcomings of current stoppering devices, this utility model provides a stoppering device with a buffer platform. Through the buffer structure design, it can effectively absorb and buffer the impact force when the stopper head presses down on the stopper body and transmits the force to the container, significantly reducing the risk of glass and plastic bottles breaking.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] According to one aspect of the present invention, a stopper applicator with a buffer platform is provided, comprising:
[0006] A stopper head is used to apply a stopper to a container;
[0007] A container placement platform is located below the stopper head and is used to support the container to be stoppered. The container and the stopper head are on the same vertical line. The container placement platform is equipped with a buffer structure inside.
[0008] The buffer structure includes an elastic element for providing elastic cushioning when the stopper head presses down on the container.
[0009] Optionally, the stopper head includes a nitrogen filling head body, a stopper rod, and a driving mechanism. The nitrogen filling head body has a first channel extending through the bottom, and the stopper rod has a second channel extending through the bottom. The second channel is connected to a vacuum passage, which is configured to evacuate the inside of the stopper rod so that the bottom of the stopper rod can hold the stopper of the sealed container. The lower end of the stopper rod is disposed in the first channel, and the upper end is connected to the driving mechanism. Under the drive of the driving mechanism, the stopper rod moves within the first channel inside the nitrogen filling head body to insert the stopper into the container opening.
[0010] Optionally, the first channel of the nitrogen filling head body is connected to a vacuum path and a nitrogen path, respectively. The vacuum path is configured to perform a vacuuming operation inside the container, and the nitrogen path is configured to fill the container with nitrogen.
[0011] Optionally, the buffer structure may further include guide posts for constraining the compression direction of the elastic element.
[0012] Alternatively, the elastic element is a spring, which is sleeved on the guide post.
[0013] Optionally, a guide sleeve is also fitted below the elastic element on the guide post, and the guide post slides within the guide sleeve.
[0014] Optionally, the stopper device may further include a container mounting plate having a plurality of mounting slots formed thereon, each mounting slot being configured with a container mounting platform.
[0015] Optionally, a pressure sensor is embedded in the mounting slot of the container mounting plate. The pressure sensor is connected to the drive mechanism. When the container pressure is detected to exceed the threshold, the drive mechanism stops the pressing and plugging action.
[0016] Optionally, the surface of the container placement platform is formed with a positioning groove that matches the outer contour of the container.
[0017] The advantages of this utility model are:
[0018] 1. Effectively buffers rigid impacts and prevents container breakage: By setting a buffer structure inside the container mounting platform, the impact force can be effectively absorbed and buffered when the stopper head presses down on the stopper and transmits the force to the container, significantly reducing the risk of glass bottles, plastic bottles and other containers breaking during the stoppering process.
[0019] 2. The device integrates efficient vacuuming and nitrogen filling functions, enabling gas replacement inside the container before sealing.
[0020] 3. The pressure sensor monitors the actual pressure on the container during the plugging process and automatically stops the plugging action when the pressure exceeds the safety threshold to prevent the container from deforming or breaking due to excessive pressure.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] like Figures 1-6 As shown, a stoppering device with a buffer platform includes: a stopper head 1 for applying a stopper to a container 3; a container platform 2 disposed below the stopper head 1 for supporting the container to be stoppered, wherein the container 3 and the stopper head 1 are on the same vertical line; the container platform 2 is provided with a buffer structure inside; the buffer structure includes an elastic element 21 for providing elastic buffering when the stopper head 1 presses down on the container.
[0032] Specifically, when the stopper head 1 moves downward to press the stopper body, the elastic element 21 (such as a spring) inside the container mounting platform 2 is compressed. The elastic element 21 deforms to absorb the impact kinetic energy and avoid rigid collision. The buffer stroke can reach 5-10mm, and the instantaneous impact force on the container is reduced by more than 70%. At the same time, the stiffness of the elastic element 21 is adjustable, which can be compatible with containers with different pressure resistance, such as glass bottles and PET bottles.
[0033] Example 2
[0034] like Figures 1-6As shown, a stoppering device with a buffer platform includes: a stopper head 1 for applying a stopper to a container 3; a container platform 2 disposed below the stopper head 1 for supporting the container to be stoppered, wherein the container 3 and the stopper head 1 are on the same vertical line; the container platform 2 is provided with a buffer structure inside; the buffer structure includes an elastic element 21 for providing elastic buffering when the stopper head 1 presses down on the container.
[0035] Specifically, when the stopper head 1 moves downward to press the stopper body, the elastic element 21 inside the container mounting platform 2 is compressed. The deformation of the elastic element 21 absorbs the impact kinetic energy and avoids rigid collision. The buffer stroke can reach 5-10mm, reducing the instantaneous impact force on the container by more than 70%. At the same time, the stiffness of the elastic element 21 is adjustable, making it compatible with containers of different pressure resistance, such as glass bottles and PET bottles.
[0036] Further, the stopper head 1 includes a nitrogen filling head body 11, a stopper rod 12, and a drive mechanism 13. The nitrogen filling head body 11 has a first channel 111 extending through the bottom, and the stopper rod 12 has a second channel 121 extending through the bottom. The second channel 121 communicates with a vacuum circuit. The vacuum circuit is configured to evacuate the inside of the stopper rod 12, allowing the bottom of the stopper rod 12 to adhere to the stopper of the sealed container. The lower end of the stopper rod 12 is located within the first channel 111, and the upper end is connected to the drive mechanism 13. Driven by the drive mechanism 13, the stopper rod 12 moves within the first channel 111 inside the nitrogen filling head body 11 to insert the stopper into the container opening. When the vacuum circuit is activated, air is drawn through the second channel 121 of the stopper rod 12, creating a negative pressure at the bottom of the rod to adsorb the stopper. The cylinder, acting as the drive mechanism 13, pushes the stopper rod 12 downwards along the first channel 111 of the nitrogen filling head body 11, pressing the stopper into the container opening, while simultaneously closing the vacuum circuit. Vacuum adsorption fixes the plug, avoiding displacement caused by mechanical clamping.
[0037] Furthermore, the first channel 111 of the nitrogen filling head body 11 is connected to both a vacuum path and a nitrogen path. The vacuum path is configured to perform a vacuuming operation inside the container, and the nitrogen path is configured to fill the container with nitrogen. During the vacuuming stage: the vacuum path connects to the first channel 111 to extract air from the container to the target vacuum level; during the nitrogen filling stage: the nitrogen path injects high-purity nitrogen into the first channel 111 to replace residual oxygen until the oxygen content is <0.5%. Vacuuming and nitrogen filling are completed in a single station, improving work efficiency.
[0038] Furthermore, the buffer structure also includes a guide post 22 for constraining the compression direction of the elastic element 21. The guide post 22 penetrates vertically through the center of the elastic element 21, and the elastic element 21 moves along the axial direction of the post when compressed. This ensures that the direction of force on the container coincides with the axis of the stopper head 1, preventing sealing leaks caused by bottle neck tilting.
[0039] Furthermore, the elastic element 21 is a spring, which is sleeved on the guide post 22. The spring stiffness matches the compressive strength of the container, and it will automatically spring back after the plug is inserted.
[0040] Furthermore, a guide sleeve 23 is fitted below the elastic element 21 on the guide post 22, and the guide post slides within the guide sleeve 23. The guide sleeve 23 bears lateral forces and protects the spring from non-axial loads.
[0041] Furthermore, the stoppering device also includes a container mounting plate 4, on which multiple mounting slots 41 are formed, and each mounting slot 41 is equipped with a container mounting platform 2. The container mounting plate 4 has 12-48 mounting slots 41, each slot independently mounts a buffer container mounting platform 2, and each container mounting platform 2 corresponds to a stoppering head 1, which can greatly improve production efficiency, and a single point of failure will not affect the whole.
[0042] Furthermore, a pressure sensor is embedded in the mounting groove 41 of the container mounting plate 4. The pressure sensor is connected to the drive mechanism 13. When the container pressure exceeds a threshold, the drive mechanism 13 stops the pressing and plugging action. The pressure sensor is embedded in the bottom of the mounting groove 41 to detect the container pressure. When the pressure is greater than the threshold, the sensor sends a signal to the drive mechanism 13, which can quickly stop. The specific threshold can be adjusted according to different containers.
[0043] Furthermore, the platform of the container mounting table 2 has a positioning groove that matches the outer contour of the container. The positioning groove is machined according to the outer contour of the container and engages with the bottom of the container, ensuring that the stopper head 1 is coaxial with the container opening.
[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
