Description

Technical Field

[0001] This utility model relates to the field of capping mechanism technology, specifically a capping mechanism for a vacuum capping machine. Background Technology

[0002] A vacuum capping machine is a device used to tighten and loosen caps on containers such as glass and plastic bottles after dispensing. It is mainly used to remove air from the bottle after filling and before sealing, thereby increasing the product's shelf life and freshness. Vacuum capping machines are commonly used for vacuum packaging of food, honey, condiments, and bottled foods, and are suitable for industries such as light industry.

[0003] The vacuum capping machine uses a sealed structure that fully forms a vacuum chamber, allowing the bottle to be completely placed in the vacuum chamber for vacuuming and capping. It utilizes mature electrical control technology and high-performance pneumatic components to achieve the rotational drive of the cylindrical, fully sealed vacuum chamber.

[0004] However, traditional vacuum capping machines lack a bottle-limiting structure during capping, which easily leads to bottles tipping over during actual processing. The machines cannot effectively hold and limit the bottles, causing them to fall and become damaged, affecting product quality and reducing overall work efficiency. Therefore, this invention proposes a capping mechanism for a vacuum capping machine. Utility Model Content

[0005] The purpose of this invention is to provide a capping mechanism for a vacuum capping machine to solve the problems mentioned in the background art.

[0011] Preferably, a vacuum tube connector is fixedly installed on the outer wall of the back side of the vacuum shroud.

[0012] Preferably, the vacuum hood is positioned over the outside of the capping head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 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.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0024] Please see Figure 1-4 An embodiment of this utility model provides a capping mechanism for a vacuum capping machine, comprising a lower base plate 1, with columns 2 fixedly installed at the four corners of the upper surface of the lower base plate 1 by welding, an upper top plate 3 fixedly installed between the tops of the four columns 2, and side plates 4 fixedly installed between the upper top plate 3 and both sides of the lower base plate 1 by welding, with pneumatic cylinders 5 fixedly installed on the outer walls of the two side plates 4 by bolts, the output end of the pneumatic cylinder 5 being movably connected to a pneumatic rod, a connecting plate 6 fixedly installed at the top of the pneumatic rod, a connecting column 7 fixedly installed on one side of the outer wall of the connecting plate 6, and a bottle-holding component 8 fixedly installed between the tail ends of the two connecting columns 7, the bottle-holding component 8 adopting an arc-shaped structure design;

[0025] As described above, when the external bottle is placed directly below the capping mechanism of this utility model, the two pneumatic cylinders 5 can drive the pneumatic rod to retract. When the pneumatic rod retracts inward, it will drive the two bottle-holding parts 8 at the bottom to retract inward simultaneously through the connecting column 7. At this time, the distance between the two bottle-holding parts 8 is shortened. Thus, the two inwardly retracting bottle-holding parts 8 can hold and limit the bottle that needs to be capped, which can effectively prevent the bottle from tipping over or becoming unstable during capping, avoid the bottle from falling and being damaged, effectively improve the processing quality of the product during capping, and eliminate the need to pick up the tipped bottle, which can effectively improve the overall work efficiency and has good practicality.

[0026] Furthermore, the capping mechanism of this utility model has its own bottle-holding structure for limiting and clamping the bottle body. Therefore, there is no need to make additional modifications to the vacuum capping machine. It has the structural integrity of vacuum capping and bottle holding, and the overall structure is more convenient to use. Simply install the capping mechanism of this utility model on a traditional vacuum capping machine to achieve a good bottle-holding effect. It can be applied to more traditional vacuum capping machines. At the same time, the overall structure of the bottle-holding component is simple, easy to install and maintain, has lower manufacturing and maintenance costs, and is more practical.

[0027] In this embodiment, the two bottle-holding components 8 are arranged in a mirror image opposite each other. Anti-slip pads are glued to the inner walls of both bottle-holding components 8. The anti-slip pads are silicone anti-slip pads. The silicone anti-slip pads can improve the contact effect with the bottle body and have good anti-slip properties. At the same time, the silicone material can improve the flexible contact effect with the bottle body, avoid hard contact that may damage the quality of the glass material, and improve the overall use effect.

[0028] In this embodiment, in order to ensure normal capping operation, a capping motor 9 is fixedly installed at the center of the upper surface of the lower base plate 1 by bolts. A rotating shaft 10 is fixedly connected to the output shaft of the capping motor 9. A capping head 11 is fixedly installed on the outer wall of the bottom end of the rotating shaft 10. Thus, the capping motor 9 can drive the capping head 11 at the bottom end to rotate through the rotating shaft 10, thereby ensuring normal capping operation.

[0029] In this embodiment, in order to ensure the normal vacuum capping operation of the bottle, a vacuum upper plate is sleeved on the outside of the rotating shaft 10 through a bearing. The bearing structure is designed so that when the rotating shaft 10 rotates, the vacuum upper plate will not rotate synchronously due to the action of the bearing ring, thus ensuring the normal use of the vacuum structure. A vacuum cover 12 is fixedly installed on the outer wall of the vacuum upper plate, and the vacuum cover 12 covers the outside of the capping head 11.

[0030] For details, please refer to the appendix of the instruction manual. Figure 2As shown, a vacuum tube connector 13 is fixedly installed on the outer wall of the back of the vacuum chamber 12. The vacuum tube connector 13 can be connected to an external vacuum pump pipe, so that the bottle inside the vacuum chamber 12 can be vacuumed.

[0031] Working principle: When in use, the capping mechanism of this utility model can be installed on a vacuum capping machine to ensure normal use. The capping mechanism of this utility model can be connected to an external vacuum pump pipeline through the vacuum pipe connector 13, so as to perform vacuum treatment on the bottle inside the vacuum cover 12.

[0032] In actual use, the outer bottle is conveyed to the bottom of the capping mechanism via a conveying structure or a robotic arm. At this time, the two pneumatic cylinders 5 drive the pneumatic rod to retract. When the pneumatic rod retracts inward, it drives the two bottle-holding parts 8 at the bottom to retract inward synchronously through the connecting column 7. At this time, the distance between the two bottle-holding parts 8 is shortened. In this way, the two inwardly retracting bottle-holding parts 8 can hold and limit the bottle to be capped, which can effectively prevent the bottle from tipping over or becoming unstable during capping, avoid the bottle from falling and being damaged, effectively improve the processing quality of the product during capping, and eliminate the need to pick up tipped bottles, which can effectively improve the overall work efficiency and has good practicality.

[0033] The silicone anti-slip pads improve the contact between the silicone pads and the bottle, providing better anti-slip properties. The silicone material also enhances the flexible contact with the bottle, preventing damage to the glass material from hard contact and improving the overall usability.

[0034] After the bottle-holding structure holds the bottle tightly, the vacuum pump can evacuate the cavity of the bottle through the vacuum pipe and vacuum hood 12 to prevent air from entering the bottle. Then, the capping motor 9 can drive the capping head 11 at the bottom to rotate through the rotating shaft 10, thereby completing the normal vacuum rotary capping process and ensuring the normal capping use of the vacuum capping agent.

[0035] After vacuum capping is completed, the bottle holder 8 moves outward and unfolds under the action of the pneumatic cylinder 5. At this time, the bottle holder 8 releases the bottle body after vacuum capping, the conveying structure operates, and the capped bottle body is sent out. The subsequent bottle body enters directly below the capping mechanism and is processed in a cyclical manner in the above way, thus completing the cyclical automated vacuum capping operation.

[0036] In summary, the capping mechanism of this utility model inherently possesses a bottle-holding structure for limiting and clamping the bottle body. Therefore, no additional modifications or additions are required to the vacuum capping machine. It features an integrated structure for both vacuum capping and bottle holding, making the overall structure more convenient to use. Simply installing the capping mechanism of this utility model on a traditional vacuum capping machine will achieve a good bottle-holding effect. It can be applied to a wider range of traditional vacuum capping machines. Furthermore, the bottle-holding component has a simple overall structure, is easy to install and maintain, has lower manufacturing and maintenance costs, and is more practical.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
