Description
- 1. Field of Invention
- The present invention relates to a capping device, and more particularly to a single knife capping device which is capable of making a wide variety of sealing caps, such as those used in pharmaceutical or food industry.
- 2. Description of Related Arts
- A conventional capping machine usually comprises a sealing device, a knife assembly, a supporting device, a transmission device, a dynamics wheel assembly, and a driving wheel. Before the capping machine is operated, a predetermined cap is placed on an opening of a bottle. The driving wheel is then arranged to move the bottle and the cap to a position underneath the sealing device and on top of the supporting device. When the capping machine operates, the supporting device moves the bottle and the cap toward the sealing device, which is arranged to rotatably engage with the cap so as to drive the cap to rotate with respect to the bottle. At the same time, the knife assembly is driven by the dynamics wheel assembly to move toward the sealing device for pressing against the cap and the bottle so as to tighten the engagement between the cap and the bottle. The knife assembly and the supporting device are then moved back to their original position for completing a pressing cycle. An advantage of this type of conventional capping machine is that it has simple structure. However, a major disadvantage is that the sealing performance is rather unstable, especially when a friction between the cap and the bottle is not sufficiently large enough. Moreover, when the supporting member moves the bottle upwardly toward the sealing device, the cap may fall off the bottle very easily.
- The invention is advantageous in that it provides a capping machine which is simple in structure, stable when operating and is capable of performing high quality capping procedures.
- According to the present invention, the foregoing and other objects and advantages are attained by providing a capping machine, comprising a depressing member, a cap pressing device connected to the depressing member, a supporting device, a transmission device, a first driving wheel, a second driving wheel, and an actuating wheel, wherein the first driving wheel is rotatably connected to the depressing member, wherein the depressing member comprises a driver member, while the cap pressing device comprises a driver ring, wherein the driver member is received in the driver ring, wherein the depressing member is engaged with the first driving wheel such that the first driving wheel is arranged to drive the depressing member and the cap pressing device in a vertical direction, wherein the depressing member is driven to rotate by the transmission device, while the supporting device is also rotatably connected to the transmission device so as to rotate with the depressing member in a synchronized manner.
- The capping machine further comprises an auxiliary ring movably mounted on the cap pressing device, a gear assembly mounted on the cap pressing device at a position underneath the auxiliary ring, and a resilient element mounted between the auxiliary ring and the gear assembly for normally exerting an upward force to the cap pressing device.
- The present invention has the following advantages over conventional arts:
-
- 1. The capping machine of the present invention is simple in structure, stable in operation and is capable of producing high quality performance. The engagement between the bottle cover and the bottle is of very high quality and has very good aesthetic appearance.
- 2. In the present invention, the supporting device is also rotatably connected to the transmission device so as to rotate with the depressing member in a synchronized manner. This substantially resolves the problem of uneven capping of bottle which exists in conventional arts. Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

- Referring to
FIG. 1 of the drawings, a capping machine according to a preferred embodiment of the present invention is illustrated, in which the capping machine comprises a main frame, adepressing member 1, a cappressing device 2 connected to thedepressing member 1, a supportingdevice 3, atransmission device 4, afirst driving wheel 5, asecond driving wheel 6, and an actuatingwheel 16. The firstdriving wheel 5 is mounted on the main frame, and is rotatably connected to thedepressing member 1. Thedepressing member 1 comprises a driver member 7, while the cappressing device 2 comprises adriver ring 8, wherein the driver member 7 is received in thedriver ring 8. Thedepressing member 1 is engaged with the first drivingwheel 5 such that the first drivingwheel 5 is arranged to drive thedepressing member 1 and the cap pressingdevice 2 in a vertical direction with respect to the main frame. Moreover, thedepressing member 1 is driven to rotate by thetransmission device 4. The capping machine further comprises afirst driving arm 12 connecting between the cappressing device 2 and thesecond driving wheel 6, asecond driving arm 13 provided at a lower end portion of the cappressing device 2, and apressing knife 14 mounted to thesecond driving arm 13, wherein the cappressing device 2 is driven to move by thesecond driving wheel 6 so as to drive thesecond driving arm 13 and thepressing knife 14 to move towards or away from thedepressing member 1. On the other hand, the supportingdevice 3 is also rotatably connected to thetransmission device 4 so as to rotate with thedepressing member 1 in a synchronized manner. - There may exist a gap between the driver member 7 and the
driver ring 8. The capping machine further comprises anauxiliary ring 9 movably mounted on the cappressing device 2, agear assembly 10 mounted on the cappressing device 2 at a position underneath theauxiliary ring 9, aresilient element 11 mounted between theauxiliary ring 9 and thegear assembly 10 for normally exerting an upward force to the cappressing device 2. Moreover, theresilient element 11 can also be used to minimize the gap between the driver member 7 and thedriver ring 8. When the cappressing device 2 is driven to move downwardly, the driver member 7 and thedriver ring 8 ensure a relatively constant distance between the pressing knife and a depressinghead 15 of thedepressing member 1. This enables consistent pressing performance of the capping machine of the present invention. - The capping machine of the present invention operates as follows: the capping machine is for sealing a bottle by a predetermined bottle cap. The bottle and the bottle cap are arranged to be placed in between the
depressing head 15 and the supportingdevice 3. Thedepressing member 1 is then driven to move downwardly along the main frame by the firstdriving wheel 5. As such the bottle and the bottle cap are sandwiched between thedepressing member 1 and the supportingdevice 3. At the same time, thedepressing member 1 and the supportingdevice 3 are driven to rotate in a synchronized manner. Thedepressing head 15 is arranged to bias against the bottle cap while the cappressing device 2 is also driven to move downwardly as guided by the driver member 7 and thedriver ring 8. At the same time, the pressingknife 14 is driven to move horizontally by thesecond driving wheel 6 to press against an engaging portion between the bottle cap and the bottle for sealing the bottle by the bottle cap. After the sealing of the bottle is accomplished, the pressingknife 14 is driven to move away from the bottle cap by thesecond driving wheel 6, while thedepressing member 1 and the cappressing device 2 are moved upwardly to release the pressing vertical pressing force against the bottle and the bottle cap. This completes one pressing cycle. From the above-mentioned operation, it can be appreciated that the bottle will be evenly sealed by the bottle cover. Moreover, since thedepressing member 1 and the supportingdevice 3 are aligned with each other, the bottle cap will engage with the bottle in a smooth and tight manner. This provides a stable, desirable and reliable technical effect of the present invention. - One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting. It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purpose of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
