Description

Technical Field

[0001] This utility model relates to the technical field of filling and capping machines, and in particular to a capping system. Background Technology

[0002] Crimping is a process used in industries such as pharmaceuticals and food to seal bottled products. Taking a filling and capping machine in the pharmaceutical field as an example, its crimping system is mainly used to achieve the crimping and sealing of the cap and the liquid bottle.

[0003] Existing capping devices typically include end pressing sections, capping blades, and other structures. For example, Chinese Patent No. CN104743481B discloses a capping device that, during operation, a drive mechanism drives a hollow shaft 10 to move downwards; after the pressing head 41 contacts the cap, the hollow shaft 10 continues to move downwards... until the capping blade 80 rotates to the corresponding position of the bottle and cap, the capping operation can be performed; an external drive mechanism drives the pressing head shaft 40 to rotate the pressing head 41, and the support component at the bottom of the bottle also rotates, so that the capping blade 80 can complete the capping operation while the bottle and cap are rotating together.

[0004] In the above scheme, during the capping process, the external drive mechanism drives the pressure head shaft, which in turn drives the bottle, the cap, and the bottle support components to rotate. The bottle is subjected to concentrated force on one side of the pressure head shaft, which can easily lead to uneven force distribution, affecting its stability and thus affecting the capping effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a capping system.

[0021] Preferably, the bearing portion further includes a bushing and an elastic element;

[0022] The bushing is fitted around the outer periphery of the connecting shaft and is circumferentially limited and axially slidingly connected to the connecting shaft.

[0023] The bushing is rotatably mounted to the connecting part via a bearing.

[0024] The elastic element is connected between the bushing and the placement seat so that when there is no force on the upper end of the liquid bottle, it drives the placement seat, the base plate and the connecting shaft to move axially upward synchronously.

[0025] Preferably, it also includes a limiting sleeve, which is detachably installed in the placement groove;

[0026] The inner wall of the limiting sleeve is used to abut against the outer wall of the liquid bottle.

[0027] Preferably, the bottom wall of the placement groove is provided with an anti-slip pad;

[0036] This utility model provides a capping system in which, when the supporting unit moves to the processing area, the capping device moves down to abut against the cap on the liquid bottle, while the driving device moves up to connect with the supporting unit. This achieves axial positioning of the supporting unit and the liquid bottle, ensuring their stability. Simultaneously, the driving device drives the supporting unit and the liquid bottle to rotate synchronously, thus realizing the capping process. In other words, the capping system provided by this utility model, through the cooperation of the supporting unit and the capping device and driving device distributed at the upper and lower ends of the supporting unit, can achieve axial positioning of the supporting unit and the liquid bottle during the capping process, ensuring their stability and thus guaranteeing the capping effect.

[0051] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0052] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] See Figures 1 to 11 This utility model embodiment provides a capping system for use in conjunction with the annular conveying device 100 of a filling and capping machine.

[0055] The capping system includes a capping device 1, a drive device 2, and a carrier device 3. The drive device 2 is located below the capping device 1, and a processing area is formed between the two. The carrier device 3 includes a connecting part 31 and a supporting part 32 for placing the liquid bottle 200.

[0056] Specifically, the connecting part 31 is used to connect the annular conveying device 100 and the carrying part 32 so that it can drive the carrying part 32 and the liquid bottle 200 to the processing area; the carrying part 32 is rotatably mounted on the connecting part 31. When the carrying part 32 runs to the processing area, the capping device 1 can move down to abut against the cap 300 at the upper end of the liquid bottle 200, and the driving device 2 can move up to connect with the carrying part 32 so as to drive the carrying part 32 and the liquid bottle 200 to rotate circumferentially.

[0057] It is easy to understand that in the above scheme, when the supporting part 32 moves to the processing area, the capping device 1 can move down to abut against the cap 300 on the liquid bottle 200, while the driving device 2 can move up to connect with the supporting part 32. This achieves axial positioning of the supporting part 32 and the liquid bottle 200, ensuring their stability. Simultaneously, the driving device 2 drives the supporting part 32 and the liquid bottle 200 to rotate synchronously, thus realizing the capping process. In other words, the capping system provided by this utility model, through the supporting part 32 and the capping device 1 and driving device 2 distributed at the upper and lower ends of the supporting part 32, works together to achieve axial positioning of the supporting part 32 and the liquid bottle 200 during the capping process, ensuring their stability and thus guaranteeing the capping effect.

[0058] It is worth noting that this embodiment uses the example of the carrier device 3 being connected to the annular conveyor device 100, meaning that the carrier device 3 is movable. Of course, in other embodiments, the carrier device 3 can also be directly installed in the processing area. It is also worth noting that the carrier device 3 being located in the processing area indicates that the carrier device 3 can perform the capping process when it is in this position.

[0059] See Figures 1 to 11 The capping device 1 includes a pair of end capping parts 11 and side capping parts 12, and the driving device 2 includes a pair of lifting parts 21 and rotary driving parts 22. The end capping parts 11, the lifting parts 21 and the bearing parts 32 are arranged in a one-to-one correspondence. When the bearing parts 32 are located in the processing area, the central axis of the bearing parts 32 coincides with the central axis of the corresponding end capping parts 11 and the lifting parts 21, so that the liquid bottle 200 is subjected to force along the central axis direction, making the force more uniform.

[0060] Specifically, each carrier device 3 includes two bearing parts 32, and correspondingly, two end face rolled-up parts 11, two side face rolled-up parts 12, two lifting parts 21, and two rotation drive parts 22 are also provided. Of course, in other embodiments, one, three, or more bearing parts 32 may be provided, and correspondingly, one, three, or more end face rolled-up parts 11, two side face rolled-up parts 12, one lifting part 21, and one rotation drive part 22 may also be provided.

[0061] It is understandable that having multiple support units 32 facilitates the simultaneous capping process of multiple liquid bottles 200. However, correspondingly, the force exerted on the carrier device 3 during the capping process and the operation of the liquid bottles 200 is also relatively large. Therefore, in this embodiment, the support units 32 of each carrier device 3 are preferably set to two, and the annular conveyor 100 can simultaneously convey multiple carrier devices 3, which can both avoid excessive force on the carrier device 3 and increase the capping efficiency to a certain extent.

[0062] Specifically, the side capping portion 12 is located on one side of the end capping portion 11 and can be moved to align with the bottleneck 201 of the liquid bottle 200.

[0063] Furthermore, the end-face crimping part 11 can cooperate with the driving device 2 to realize the crimping process on the end face of the cap 300. That is, the end-face crimping part 11 can move downward and apply downward pressure to the upper end of the liquid bottle 200. The lifting part 21 of the driving device 2 can move upward and apply upward thrust to the lower end of the liquid bottle 200 through the bearing part 32, thereby realizing the end-face crimping process. Correspondingly, the side-face crimping part 12 can cooperate with the driving device 2 to realize the crimping process on the side of the cap 300. That is, after the end-face crimping process is completed, the side-face crimping part 12 can move radially along the bottleneck 201 and push a part of the side wall of the cap 300 to abut against the bottleneck 201. Then, the rotation driving part 22 of the driving device 2 can drive the lifting part 21, the bearing part 32 and the liquid bottle 200 to rotate synchronously, thereby completing the side-face crimping process.

[0064] Specifically, in order to reduce the number of power sources, in this embodiment, the rotary drive unit 22 includes a power source and a transmission unit that corresponds one-to-one with the lifting unit 21. The transmission unit includes a gear 221 and a connecting sleeve 222 that are fixedly connected. Two adjacent gears 221 mesh and drive each other. The connecting sleeve 222 slides axially with its corresponding lifting unit 21 and is circumferentially limited.

[0065] It is easy to understand that in the above scheme, multiple lifting sections 21 can be driven to rotate synchronously by the same power source.

[0066] It is worth noting that "axial sliding and circumferential limiting connection" means that the two connected structures can operate synchronously, and one of them can slide relative to the other. For example, a protrusion is provided on one structure, and a groove is provided on the other structure (the axial length of the groove is greater than the axial length of the protrusion), and the structure is connected by sliding between the protrusion and the groove.

[0067] Furthermore, in this embodiment, the sliding, lifting and other movements of each structure can be driven by hydraulic devices, and the rotation drive can be driven by an electric motor. These are all mature existing technologies, so they will not be described in detail.

[0068] Specifically, the support part 32 includes a placement seat 321, a base plate 322, and a connecting shaft 323 whose upper and lower ends are fixedly connected to the placement seat 321 and the base plate 322, respectively; the upper end of the placement seat 321 is provided with a placement groove 3211 for accommodating the liquid bottle 200; the lower end of the base plate 322 is provided with an abutment groove 3221 for abutting against the lifting part 21.

[0069] Furthermore, the abutment groove 3221 can be configured as an flared structure with a gradually increasing diameter from top to bottom, and the abutment groove 3221 and the lifting part 21 are tightly abutted together, and there can be sufficient friction between the two (such as increasing the surface roughness). Of course, the abutment groove 3221 and the lifting part 21 can also be circumferentially limited and connected (such as setting mutually cooperating protrusions and grooves).

[0070] Furthermore, the bearing part 32 also includes a bushing 324 and an elastic element 325; the bushing 324 is sleeved around the connecting shaft 323 and is circumferentially limited and axially slidably connected to the connecting shaft 323; the bushing 324 is rotatably mounted on the connecting part 31 through a bearing; the elastic element 325 is connected between the bushing 324 and the placement seat 321 so that when the upper end of the liquid bottle 200 is not under force, it drives the placement seat 321, the base plate 322 and the connecting shaft 323 to move axially upward synchronously.

[0071] It is easy to understand that when the upper end of the liquid bottle 200 is subjected to the abutting force of the end face crimping part 11, and the abutting groove 3221 at the lower end of the base plate 322 abuts against the upper end of the lifting part 21, the rotary drive part 22 can drive the placement seat 321, the base plate 322, the connecting shaft 323, the bushing 324, the elastic element 325, and the liquid bottle 200 to rotate axially synchronously to realize the crimping process. When the crimping process is completed, the end face crimping part 11 moves upward, the lifting part 21 moves downward, and the elastic element 325 can drive the placement seat 321, the base plate 322, and the connecting shaft 323 to move upward relative to the bushing 324, which facilitates the separation of the base plate 322 from the upper end of the lifting part 21.

[0072] See Figure 9 and Figure 10 It also includes a limiting sleeve 4, which is detachably installed in the placement groove 3211; the inner side wall of the limiting sleeve 4 is used to abut against the outer side wall of the liquid bottle 200.

[0073] Specifically, the limiting sleeve 4 and the placement groove 3211 are connected by threads.

[0074] It is easy to understand that different specifications of liquid bottles 200 usually have different diameters. In order to ensure the limiting effect on different liquid bottles 200, a limiting sleeve 4 that is adapted to different liquid bottles 200 can be set. The limiting sleeve 4 is threadedly connected to the placement groove 3211, which also facilitates the disassembly and stable installation of the limiting sleeve 4.

[0075] Furthermore, the bottom wall of the placement tank 3211 is provided with an anti-slip pad 5 to increase the friction force on the liquid bottle 200.

[0076] Furthermore, the anti-slip mat 5 can be made of elastic rubber or elastic silicone.

[0077] Due to prolonged use, the anti-slip pad 5 can easily adhere tightly to the bottom wall of the placement groove 3211 under pressure, making it difficult to disassemble. In order to reduce the difficulty of disassembly, in this embodiment, the bottom wall of the placement groove 3211 is connected to the outer wall of the placement seat 321 through the connecting channel 6.

[0078] Furthermore, the connecting channel 6 is configured as a downward-sloping straight channel.

[0079] It is easy to understand that when it is necessary to disassemble the anti-slip pad 5, an auxiliary tool (such as a push rod) can be used to penetrate the connecting channel 6 or gas can be introduced into the connecting channel 6 to push the anti-slip pad 5 away from the bottom wall of the placement groove 3211, making it easier to disassemble the anti-slip pad 5.

[0080] See Figures 1 to 11 In this embodiment, the connecting part 31 includes a first connecting plate 311, a second connecting plate 312, and a third connecting plate 313 that are detachably connected; the first connecting plate 311 is used to connect to the annular conveyor 100; the second connecting plate 312 is connected to the end of the first connecting plate 311 away from the annular conveyor 100; the third connecting plate 313 is detachably installed above the second connecting plate 312; the bearing part 32 is rotatably installed on the second connecting plate 312 and the third connecting plate 313, thereby facilitating the assembly of the carrier device 3.

[0081] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
