Description

Technical Field

[0001] The utility model relates to a container closing device, belonging to the technical field of food and medicine machinery and equipment. Background Art

[0002] Container sealing technology is widely used in the food and pharmaceutical packaging machinery fields. However, the current common method of sealing containers is to vacuum-load the closure components and then seal the container (such as plugging). This method is widely applicable and can load a variety of plugs, including soft, hard, and special-shaped ones. However, it requires a supporting vacuum system to complete the operation, resulting in a relatively complex device. In the pharmaceutical canning field, the piping system formed by the vacuum system also needs to be sterilized, which makes the operation complicated. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a device capable of loading a plug made of soft material (hereinafter referred to as the plug) to seal a container.

[0004] In order to solve the above problems, the utility model provides a container closing device, which includes a container conveying device for conveying containers, a plug sorting mechanism for conveying plugs, a plug ejecting mechanism for ejecting the plugs from the plug sorting mechanism, a plug remover for transporting the ejected plugs to above the container, a rotating mechanism for rotating the plug remover, a lifting mechanism first for lifting the plug remover, an upper plug rod for pressing the plug into the container, and a lifting mechanism second for lifting the upper plug rod.

[0005] Preferably, the upper plug rod is connected to the second lifting mechanism through a shaft rod.

[0006] More preferably, the middle portion of the plug remover is connected to a ball spline, the plug remover is connected to the rotating mechanism and the lifting mechanism through the ball spline, and the shaft is passed through the ball spline.

[0007] Furthermore, it also includes a fixing seat for limiting and protecting the ball spline.

[0008] Preferably, the container conveying device is arranged on a table, a fixed plate is provided under the table, the rotating mechanism is arranged between the table and the fixed plate, the plugging mechanism is arranged on the fixed plate, and its output end extends through the table to the discharge hole of the plugging mechanism, and a fixing frame for fixing the lifting mechanism one and the lifting mechanism two is provided on the bottom surface of the fixed plate.

[0009] Preferably, the plug remover is provided with a through hole for interference fit with the plug.

[0010] More preferably, the plug remover is disc-shaped, with through holes distributed on its edge, wherein any two through holes are simultaneously located above the discharge hole of the plug sorting mechanism and the container conveying device.

[0011] This device controls and changes the positional relationship between the plug remover and the container on the container transmission device through a lifting and rotating mechanism, such as moving away from or in contact, so as to cooperate with the plug removal and plug assembly in subsequent processes.

[0012] The plug loading device for soft materials provided by the utility model can seal containers in intermittent operation without the need for vacuum. The utility model can operate without plugging when there is no container, ensuring that plugs do not fall into the equipment, maintaining a clean environment. In addition, by changing the plug entry channel of the plug sorting mechanism and the installation angle of the plug remover, the utility model can simultaneously plug multiple containers, thereby increasing production.

[0017] In order to make the present invention more clear and easy to understand, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figure 1-2 The figure shows a container closure device provided by the present invention, which includes a container conveying device 9 for conveying a container 8, a plug sorting mechanism 2 for conveying a plug 7, a plug ejecting mechanism 3 for ejecting the plug 7 from the plug sorting mechanism 2, a plug remover 6 for transporting the ejected plug 7 to the top of the container 8, a rotating mechanism 10 for rotating the plug remover 6, a lifting mechanism 12 for lifting the plug remover 6, an upper plug rod 1 for pressing the plug 7 into the container 8, and a lifting mechanism 2 5 for lifting the upper plug rod 1. The upper plug rod 1 is connected to the lifting mechanism 2 5 via a shaft 4.

[0020] The plug remover 6 is disc-shaped, with through-holes distributed along its edge for an interference fit with the plug 7. Any two of these through-holes are located simultaneously above the discharge port of the plug sorting mechanism 2 and the container transfer device 9. The center of the plug remover 6 is connected to a ball spline 11, which connects the plug remover 6 to the rotating mechanism 10 and the lifting mechanism 12. The shaft 4 is inserted into the ball spline 11.

[0021] The container transfer device 9 is mounted on a tabletop, with a fixed plate positioned below. A rotating mechanism 10 is positioned between the two plates. The ejector mechanism 3 is also mounted on the fixed plate, with its output end extending through the tabletop to the discharge opening of the ejector mechanism 2. A mounting seat for limiting and protecting a ball spline 11 is located on the tabletop. The upper portion of the ball spline 11 is inserted into the mounting seat and can move up and down or rotate within it. A mounting bracket for securing the first and second lift mechanisms 12 and 5 is located on the bottom surface of the fixed plate.

[0022] The container conveyor 9 and the plug sorting mechanism 2 are conventional technologies. The container conveyor 9 intermittently transports containers by controlling the start and stop of the conveyor mechanism. The basic principle of the plug sorting mechanism 2 is to neatly arrange the plugs in their own plug channels through vibration.

[0023] The working process of the above device is: the plugging device is used to add plugs and then rotates intermittently. At the same time, the container conveying device intermittently conveys the material bottle. When the through hole of the plug remover is aligned with the discharge hole of the plug sorting mechanism, the plug pushing mechanism pushes out the plug in the discharge hole of the plug sorting mechanism and plugs it into the through hole of the plug remover. At the same time, the through hole with the plug already installed is rotated to the top of the unplugged container on the container conveying device / below the upper plug rod, and the end of the upper plug rod presses the plug into the bottle mouth of the container.

[0024] Example 2

[0025] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that a numerical sensor 13 is added to the container transport device 9 .

[0026] The counting sensor calculates whether there is no container on the container conveying device, and feeds back to the driving mechanism of the plugging mechanism (the servo motor driving the lifting mechanism 2), so that the plugging operation is not performed when there is no container.

[0027] Example 3

[0028] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that, in order to meet the needs of different production volumes, the plug sorting mechanism is provided with two plug feeding channels, the discharge holes of the two plug feeding channels respectively correspond to the two adjacent through holes of the plug remover, and the plug pushing mechanism is correspondingly provided with two output ends corresponding to the two through holes; the two adjacent through holes of the plug remover on the other side simultaneously correspond to the tops of the two adjacent containers on the container transmission device, and the upper plug rod is provided with two ends for pressing the plugs in the two through holes.

[0029] This embodiment performs plugging operations on multiple containers simultaneously by changing the plug entry channel of the plug sorting mechanism and the installation angle of the plug remover.
