Description

Technical Field

[0001] This application relates to the field of stoppering devices, and more particularly to a vacuum stoppering device. Background Technology

[0002] Vacuum stoppering devices have been widely used in the filling and stoppering process of the food, pharmaceutical, and cosmetic industries.

[0003] In related technologies, vacuum-assisted stoppering devices mainly include a vacuum structure, a stoppering sleeve assembly, and a drive structure. During operation, the rubber stopper is first placed into the stoppering sleeve assembly, and the drive structure moves the device above the part to be stoppered. Subsequently, the vacuum structure descends and tightly seals against the stopper inlet of the part to be stoppered, and the vacuum pump is activated to create a vacuum. Once the set vacuum level is reached, the drive structure pushes the stoppering sleeve assembly to press the rubber stopper into the part to be stoppered. Under atmospheric pressure, the rubber stopper slides to the surface of the liquid, completing the stoppering process.

[0004] However, the rubber stopper may detach prematurely due to gravity or pressure difference before the vacuum is fully established, resulting in residual air bubbles inside the syringe and affecting the sealing effect. Utility Model Content

[0005] This application provides a vacuum stopper device to prevent residual air bubbles in the syringe from affecting the seal during the stoppering process.

[0006] This application provides a vacuum plugging device, comprising:

[0007] A stopper assembly, on which a rubber stopper is placed, is used to push the rubber stopper into the workpiece to be processed;

[0008] A vacuum assembly includes a vacuum guide plug arm and a vacuum component. The vacuum guide plug arm has a guide plug cavity for the rubber stopper to pass through, so that the rubber stopper moves into the workpiece to be processed. The vacuum component is connected to both ends of the guide plug cavity to simultaneously extract gas from the guide plug cavity.

Both the first vacuum channel and the second vacuum channel are connected to the vacuum component to simultaneously extract gas from the guide plug cavity.

[0011] In one possible implementation, the guide plug cavity is configured as a plurality of such cavities, which are arranged side by side and are all connected to the first vacuum channel and the second vacuum channel.

[0012] In one possible implementation, the vacuum guide plug arm is provided with a vacuum nozzle, which is in communication with the guide plug cavity and is used to connect with the workpiece to be processed.

[0013] In one possible implementation, the stopper assembly includes a mounting arm and at least one stopper, the mounting arm being connected to the drive assembly, and the stopper being disposed on the mounting arm for pushing the rubber stopper into the workpiece to be processed.

[0014] In one possible implementation, the stopper includes a first stopper rod, a second stopper rod, and a guide sleeve. The first stopper rod is connected to the drive assembly, the second stopper rod is coaxially connected to the first stopper rod, and the guide sleeve is slidably sleeved on the first stopper rod and the second stopper rod.

[0015] The guide sleeve is configured to abut against the vacuum guide plug arm to seal one end of the guide plug cavity, and the second plug rod is configured to partially slide out of the guide sleeve, abut against the rubber plug, and be inserted into the guide plug cavity.

[0016] In one possible implementation, an elastic element is provided inside the guide sleeve, the elastic element being connected to the first stopper rod, and the elastic element being configured to drive the first stopper rod to slide relative to the guide sleeve in a direction away from the vacuum guide arm.

[0019] In one possible implementation, the first stopper rod passes through the mounting arm, and a mounting block is detachably connected to the top of the first stopper rod, the mounting block abutting against the mounting arm.

[0020] This application provides a vacuum plugging device, comprising a plugging assembly, a vacuum assembly, and a drive assembly.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] Existing vacuum-sealed stopper devices mainly consist of a vacuum structure, a stopper sleeve assembly, and a drive structure. The friction between the stopper and the sleeve is controlled by the inner diameter of the sleeve to secure the stopper and prevent premature slippage. However, controlling the inner diameter of the sleeve requires balancing the amount of stopper deformation with the friction. If the inner diameter is too large, the stopper may slip due to insufficient friction; if the inner diameter is too small, it may cause excessive deformation of the stopper, especially for coated stoppers, potentially causing irreversible damage to the coating. Furthermore, existing devices often rely on a single vacuum chamber to adsorb the stopper through a vacuum nozzle. However, if the vacuum is not fully established, the stopper may detach prematurely due to gravity or pressure difference, leaving air bubbles inside the syringe and affecting the sealing effect.

[0036] This application provides a vacuum plugging device, comprising a plugging assembly, a vacuum assembly, and a drive assembly. The vacuum assembly includes a vacuum guide arm and a vacuum element. The vacuum guide arm has a guide cavity for the rubber plug to pass through, allowing it to move into the workpiece. The vacuum element is connected to both ends of the guide cavity to simultaneously extract gas from it. The plugging assembly holds the rubber plug and pushes it into the workpiece. The drive assembly is connected to both the plugging assembly and the vacuum guide arm to adjust their positions. By simultaneously vacuuming the upper and lower ends of the guide cavity, the rubber plug is secured within the cavity, ensuring smooth movement and improving product quality and production efficiency. This avoids the problem of rubber plugs automatically slipping into the workpiece before reaching the ideal vacuum pressure, resulting in a large number of residual air bubbles.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] This application provides a vacuum plugging device, referring to... Figure 1 and Figure 2 The vacuum stopper device includes a stopper assembly 100, a vacuum assembly 200, and a drive assembly 300.

[0039] The stopper assembly 100 holds a rubber stopper 110, which is used to push the rubber stopper 110 into the workpiece 1 to be processed. The vacuum assembly 200 includes a vacuum guide arm 210 and a vacuum element 220. The vacuum guide arm 210 has a guide cavity 211 for the rubber stopper 110 to pass through, allowing it to move into the workpiece 1. The vacuum element 220 is connected to both ends of the guide cavity 211 to simultaneously extract gas from it. The drive assembly 300 connects to the stopper assembly 100 and the vacuum guide arm 210 to adjust their positions.

[0040] By simultaneously evacuating the upper and lower ends of the guide plug cavity 211, the rubber stopper 110 can be stabilized within the guide plug cavity 211, ensuring that the rubber stopper 110 moves smoothly into the workpiece 1 to be processed, thus improving product quality and production efficiency. This avoids the problem of the rubber stopper 110 easily slipping into the workpiece 1 to be processed when the ideal vacuum pressure is not reached, resulting in a large number of residual air bubbles in the workpiece 1 to be processed.

[0041] In the example of this application, the component to be processed 1 is a syringe. The syringe material includes, but is not limited to, borosilicate glass, COP, etc., and the rubber stopper 110 includes, but is not limited to, coated rubber stopper 110, non-coated rubber stopper 110, etc., especially suitable for adding coated rubber stopper 110 to ready-to-use (RTU) pre-filled syringes.

[0042] The drive assembly 300 includes a first drive member 310 and a second drive member 320. The first drive member 310 is connected to the insert assembly 100 to adjust the position of the insert assembly 100. The second drive member 320 is connected to the vacuum guide arm 210 to adjust the position of the vacuum guide arm 210.

[0043] For example, the first drive component 310 includes a first lifting shaft and a drive structure. The insert assembly 100 is mounted on the lifting shaft, and the drive structure is connected to the lifting shaft. The drive structure is configured to drive the lifting shaft to move up and down. The drive structure can be a hydraulic cylinder, an electric push rod, etc.

[0044] For example, the second drive unit 320 includes a second lifting shaft and a drive structure. The first lifting shaft of the first drive unit 310 is coaxially arranged with the second lifting shaft, the second lifting shaft is sleeved on the first lifting shaft, and the drive structure is connected to the second lifting shaft to drive the second lifting shaft to move up and down. Furthermore, the insert assembly 100 is located directly above the vacuum guide arm 210. The drive structure can be a hydraulic cylinder, an electric push rod, etc.

[0045] For example, the drive assembly 300 also includes a third drive member, on which the first drive member 310 and the second drive member 320 are disposed. The third drive member is used to drive the first drive member 310 and the second drive member 320 to move up and down synchronously, so as to synchronously adjust the position of the vacuum guide plug arm 210 and the plugging assembly 100.

[0046] For example, the third driving component includes a third lifting shaft and a driving structure, with the third lifting shaft sleeved on the second driving shaft. The driving structure is connected to the third lifting shaft to drive the third lifting shaft to move up and down. The driving structure can be a hydraulic cylinder, an electric actuator, etc.

[0047] In one possible implementation, refer to Figure 2 and Figure 3 The vacuum guide arm 210 is provided with a first vacuum channel 212 and a second vacuum channel 213. The first vacuum channel 212 and the second vacuum channel 213 are respectively connected to the two ends of the guide cavity 211. The first vacuum channel 212 and the second vacuum channel 213 are both connected to the vacuum component 220 to simultaneously extract the gas in the guide cavity 211.

[0048] By setting a first vacuum channel 212 and a second vacuum channel 213 on the vacuum guide plug arm 210, and connecting these two channels to both ends of the guide plug cavity 211 and both connected to the vacuum component 220, the gas inside the guide plug cavity 211 is simultaneously extracted. This design ensures that the rubber stopper 110 is subjected to a uniform vacuum adsorption force within the guide plug cavity 211, thereby generating a stable vacuum environment at both ends simultaneously. This effectively solves the problem of the rubber stopper 110 prematurely falling off due to gravity or pressure difference in traditional single-vacuum chamber designs, significantly improving the stability of the rubber stopper 110 within the guide plug cavity 211. Simultaneously, it prevents the rubber stopper 110 from slipping into the syringe prematurely due to insufficient vacuum pressure, thus preventing a large number of air bubbles from remaining in the syringe, ensuring the smooth progress of the stopper insertion process and the reliability of the sealing effect.

[0049] In this example, the guide plug cavity 211 extends vertically through the vacuum guide plug arm 210, the first vacuum channel 212 is located at the upper part of the guide plug cavity 211 and communicates with the guide plug cavity 211, and the second vacuum channel 213 is located at the lower part of the guide plug cavity 211 and communicates with the guide plug cavity 211.

[0050] In one possible implementation, multiple guide plug cavities 211 are provided, arranged side by side, and all of them are connected to the first vacuum channel 212 and the second vacuum channel 213.

[0051] The first vacuum channel 212 and the second vacuum channel 213 are arranged parallel to each other along the length of the vacuum guide arm 210 to connect multiple guide cavities 211.

[0052] For example, there can be five guide plug cavities 211. In other examples, the number of guide plug cavities 211 can be set according to the actual situation, which will not be elaborated here. By setting multiple guide plug cavities 211, multiple parts to be processed 1 can be plugged at the same time, further improving efficiency.

[0053] For example, the vacuum component 220 includes a connecting nozzle and a vacuum pump. The connecting nozzle is fixedly connected to the vacuum guide arm 210. The end of the vacuum guide arm 210 is also provided with a communicating cavity, which communicates with the first vacuum channel 212, the second vacuum channel 213 and the connecting nozzle respectively. The connecting nozzle is connected to the vacuum pump.

[0054] For example, the vacuum pump can be a rotary vane vacuum pump, a diffusion pump, a turbomolecular pump, etc.

[0055] For example, a third seal 215 is provided at the end of the connecting nozzle. The third seal 215 is used to seal the gap between the connecting nozzle and the vacuum guide arm 210.

[0056] For example, the third seal 215 can be a sealing ring. Further, the sealing ring can be an O-ring.

[0057] In one possible implementation, a vacuum nozzle 214 is provided on the vacuum guide plug arm 210. The vacuum nozzle 214 is connected to the guide plug cavity 211 and is used to connect to the workpiece 1 to be processed.

[0058] In this application, the plugging device also includes a base for fixing the workpiece 1 to be processed. The workpiece 1 is fixed on the base, which is located at the bottom of the vacuum guide plug arm 210.

[0059] For example, the vacuum nozzle 214 is a flexible rubber nozzle. The vacuum nozzle 214 is located at the bottom inside the guide plug cavity 211 and is tightly connected to the guide plug cavity 211 to achieve a seal. When the plugging port of the workpiece 1 comes into contact with the vacuum nozzle 214, it can effectively seal the gap between the workpiece 1 and the vacuum nozzle 214, thereby achieving a seal at the bottom of the guide plug cavity 211.

[0060] In one possible implementation, refer to Figure 1 and Figure 4 The stopper assembly 100 includes a mounting arm 120 and at least one stopper 130. The mounting arm 120 is connected to the drive assembly 300. The stopper 130 is disposed on the mounting arm 120 and is used to push the rubber stopper 110 into the workpiece 1 to be processed.

[0061] For example, the vacuum plugging device further includes a plug-feeding arm 400 and a connector 500. The plug-feeding arm 400 is connected to the connector 500, which is fixed to the second drive member 320. The connector 500 is used to drive the plug-feeding arm 400 to rotate. The plug-feeding arm 400 has at least one plug-feeding groove that extends through the plug-feeding arm 400. The rubber plug 110 is placed in the plug-feeding groove. The plug-feeding arm 400 is located between the mounting arm 120 and the vacuum guide plug arm 210. When the plug-feeding arm 400 rotates to be directly above the vacuum guide plug arm 210, the plug-feeding groove coincides with the guide plug cavity 211, and the plugging member 130 pushes the rubber plug 110 into the guide plug cavity 211.

[0062] For example, the connector 500 can be a motor gear structure to drive the feeder arm 400 to rotate.

[0063] In one possible implementation, the stopper 130 includes a first stopper rod 131, a second stopper rod 132, and a guide sleeve 133. The first stopper rod 131 is connected to the drive assembly 300, the second stopper rod 132 is coaxially connected to the first stopper rod 131, and the guide sleeve 133 is slidably sleeved on the first stopper rod 131 and the second stopper rod 132.

[0064] The guide sleeve 133 is configured to abut against the vacuum guide plug arm 210 to seal one end of the guide plug cavity 211, and the second plug rod 132 is configured to partially slide out of the guide sleeve 133, abut against the rubber plug 110, and be inserted into the guide plug cavity 211.

[0065] Through the coordinated action of the first stopper rod 131, the second stopper rod 132, and the guide sleeve 133, the precise pushing and sealing operation of the rubber stopper 110 is achieved. The first stopper rod 131 is connected to the drive assembly 300, ensuring that the entire stopper 130 can be moved as needed. The second stopper rod 132 is coaxially connected to the first stopper rod 131, ensuring the stability and coaxiality of the movement. The guide sleeve 133 is slidably sleeved on the two stopper rods, serving as a guide and support.

[0066] During the operation, refer to Figure 5 The guide sleeve 133 abuts against the vacuum guide plug arm 210, sealing one end of the guide plug cavity 211 to ensure a stable vacuum environment. The second plugging rod 132 partially slides out of the guide sleeve 133, abuts against the rubber plug 110, and is inserted into the guide plug cavity 211, accurately pushing the rubber plug 110 into place. This not only improves the accuracy and reliability of plugging but also enhances the stability of the vacuum environment by sealing one end of the guide plug cavity 211, effectively preventing the rubber plug 110 from slipping or deforming during the pushing process due to vacuum instability, thereby improving the efficiency and quality of the entire plugging process.

[0067] For example, the second stopper rod 132 is threaded to the bottom end of the first stopper rod 131. The diameter of the first stopper rod 131 is larger than the diameter of the second stopper rod 132. The guide sleeve 133 has a cavity, within which both the first stopper rod 131 and the second stopper rod 132 can slide.

[0068] In one possible implementation, an elastic element 134 is provided inside the guide sleeve 133. The elastic element 134 is connected to the first stopper rod 131. The elastic element 134 is configured to drive the first stopper rod 131 to slide relative to the guide sleeve 133 in a direction away from the vacuum guide stop arm 210.

[0069] The elastic element 134 is located inside the cavity of the guide sleeve 133. One end of the elastic element 134 is connected to the bottom of the guide sleeve 133, and the other end of the elastic element 134 is connected to the end of the first stopper rod 131. The guide sleeve 133 is connected by the elastic element 134 to prevent the guide sleeve 133 from falling off.

[0070] The elastic element 134 inside the guide sleeve 133 is connected to the first stopper rod 131. Its design is to automatically push the first stopper rod 131 along the guide sleeve 133 away from the vacuum stopper arm 210 after the stoppering operation is completed, thereby causing the second stopper rod 132 to reset. This effectively avoids the complexity and potential errors of manual operation, improving the efficiency and reliability of the stoppering process. It ensures that the second stopper rod 132 can quickly return to its initial position, preparing for the next stoppering operation, reducing equipment downtime and operator workload, while also improving the automation level and continuity of the overall production process.

[0071] For example, the elastic element 134 can be a spring, which is sleeved on the second stopper rod 132. One end of the spring is fixedly connected to the bottom arm of the guide sleeve 133, and the other end is fixedly connected to the bottom of the first stopper rod 131.

[0072] For example, the second stopper rod 132 is also provided with a shoulder, which is located outside the guide sleeve 133. The shoulder is used to abut against the bottom of the guide sleeve 133, thereby restricting the position of the guide sleeve 133 and preventing the guide sleeve 133 from sliding out of the second stopper rod 132.

[0073] In one possible implementation, a first seal 135 and a second seal 136 are provided on the guide sleeve 133. The first seal 135 abuts against the second plug rod 132, and the second seal 136 abuts against the vacuum guide plug arm 210.

[0074] The first seal 135 and the second seal 136 on the guide sleeve 133 work together to seal the top of the guide plug cavity 211. The first seal 135 abuts tightly against the second plugging rod 132, ensuring that the gap between the second plugging rod 132 and the guide sleeve 133 is completely sealed during the plugging process, preventing gas leakage and maintaining a stable vacuum environment within the guide plug cavity 211. The second seal 136 abuts tightly against the vacuum guide plug arm 210, further sealing one end of the guide plug cavity 211 to prevent external gas from entering and ensuring the integrity and stability of the vacuum environment. This dual-seal design not only improves the reliability of the seal but also effectively prevents the rubber stopper 110 from slipping or deforming due to poor sealing, significantly improving the stability and success rate of the plugging process and ensuring the efficient execution of the entire plugging operation.

[0075] For example, both the first seal 135 and the second seal 136 can be sealing rings. Furthermore, the sealing ring can be an O-ring.

[0076] In one possible implementation, a third stopper rod 137 is provided on the second stopper rod 132. The diameter of the third stopper rod 137 facing the vacuum guide arm 210 is smaller than that of the second stopper rod 132. The third stopper rod 137 is used to abut against the rubber stopper 110.

[0077] This allows the third stopper rod 137 to more precisely contact the rubber stopper 110. The smaller diameter helps reduce the contact area between the third stopper rod 137 and the rubber stopper 110, thereby reducing the force required to push the rubber stopper 110 and also reducing wear on the rubber stopper 110, especially for fragile coated rubber stoppers 110. Furthermore, it ensures the rubber stopper 110 remains stable during pushing, preventing deformation or displacement of the rubber stopper 110 due to excessive contact area, thus improving the accuracy and reliability of the stopper insertion. This structural optimization of the third stopper rod 137 not only improves the pushing effect of the rubber stopper 110 but also enhances the adaptability and flexibility of the entire stopper insertion device, enabling it to better handle rubber stoppers 110 of different sizes and types.

[0078] In one possible implementation, a first stopper rod 131 is mounted on a mounting arm 120, and a mounting block 138 is detachably connected to the top of the first stopper rod 131, with the mounting block 138 abutting against the mounting arm 120.

[0079] For example, a first stopper rod 131 passes through a mounting arm 120, and a mounting block 138 is threadedly connected to the top of the first stopper rod 131 and abuts against the upper surface of the mounting arm 120 to prevent the mounting arm 120 from separating from the first stopper rod 131 from the top.

[0080] For example, a limiting shoulder 139 is also provided on the first stopper rod 131. The limiting shoulder 139 is fixed on the first stopper rod 131 and is located at the bottom of the mounting arm 120 to limit the movement of the bottom of the mounting arm 120.

[0081] The specific process of cutting in line is as follows:

[0082] Reference Figure 2 The feeding arm 400 delivers the rubber stopper 110 to the bottom of the stopper assembly 100 and the top of the vacuum guide arm 210.

[0083] Next, refer to Figure 5 The first driving component 310 drives the stopper assembly 100 to descend, pressing the rubber stopper 110 into the guide stopper cavity 211 of the vacuum guide stopper arm 210.

[0084] Subsequently, the first driving member 310 and the second driving member 320 descend simultaneously, causing the vacuum nozzle 214 to press tightly against the syringe bottle opening. At this time, the first sealing member 135, the second sealing member 136, the third sealing member 215, and the vacuum nozzle 214 work together to form a sealed cavity for the entire system.

[0085] Vacuum component 220 begins to draw a vacuum, and the first vacuum channel 212 and the second vacuum channel 213 simultaneously generate a vacuum, thereby firmly fixing the rubber stopper 110 inside the guide plug cavity 211. This avoids the problem of the rubber stopper 110 automatically sliding into the syringe before the ideal vacuum pressure is reached due to a single vacuum chamber, and prevents a large number of air bubbles from remaining in the syringe.

[0086] Once the required vacuum level is reached, the first drive unit 310 continues to descend. At this time, the guide sleeve 133 will be blocked above the vacuum guide arm 210, and the first stopper rod 131 will compress the elastic element 134, causing the second stopper rod 132 and the third stopper rod 137 to continue to descend, pressing the rubber stopper 110 into the syringe bottle mouth.

[0087] Finally, the vacuum is broken. At this point, the pressure outside the syringe is greater than the pressure inside the syringe, and the external atmospheric pressure will completely force the rubber stopper 110 into the syringe, completing the stoppering process.

[0088] The vacuum plugging device provided in this application embodiment comprises a plugging assembly 100, a vacuum assembly 200, and a drive assembly 300. The vacuum assembly 200 includes a vacuum guide arm 210 and a vacuum element 220. A guide cavity 211 is provided within the vacuum guide arm 210 for the passage of a rubber plug 110, allowing the plug 110 to move into the workpiece 1 to be processed. The vacuum element 220 is connected to both ends of the guide cavity 211 to simultaneously extract gas from it. The plugging assembly 100 holds the rubber plug 110 and is used to push the rubber plug 110 into the workpiece 1 to be processed. The drive assembly 300 is connected to both the plugging assembly 100 and the vacuum guide arm 210 to adjust their positions. By simultaneously evacuating the upper and lower ends of the guide plug cavity 211, the rubber stopper 110 can be stabilized within the guide plug cavity 211, ensuring that the rubber stopper 110 moves smoothly into the workpiece 1 to be processed, thus improving product quality and production efficiency. This avoids the problem of the rubber stopper 110 easily slipping into the workpiece 1 to be processed when the ideal vacuum pressure is not reached, resulting in a large number of residual air bubbles in the workpiece 1 to be processed.

[0089] Finally, it should be noted that other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope. The scope of this application is limited only by the appended claims.
