To achieve automated production, automated capping devices must be used in conjunction with automated filling lines to perform the capping operation, thereby improving the efficiency of automated production. However, existing aluminum capping devices for sealing plant-based beverages have some problems in practical applications. For example, plant-based beverages often contain fruit pieces, fibers, and other ingredients, which may remain at the bottle opening. If fruit pieces remain at the bottle opening during the capping process, it can lead to unstable capping and affect the sealing effect. Utility Model Content

The second venting component is disposed on the side of the first venting component close to the central axis of the second connecting plate, and the side of the first venting component close to the central axis of the second connecting plate is in contact with the second venting component.

[0034] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0035] Please see Figure 1-9 This application provides an aluminum capping device for sealing plant-based beverages, comprising: a feeding mechanism 1, a capping mechanism 2, and a clamping mechanism 3. The feeding mechanism 1 is provided with a capping station, the clamping mechanism 3 is provided on both horizontal sides of the capping station, and the capping mechanism 2 is provided on the vertical upper side of the capping station. The feeding mechanism 1 is used to transport the container bottle 4 to the capping station, and the clamping mechanism 3 is used to clamp and fix the container bottle 4 at the capping station. The capping mechanism 2 includes a capping assembly 21 and a cleaning assembly 22. The capping assembly 21 is used to carry the cap 5 that matches the container bottle 4 at the capping station and rotate it to fasten to the bottle mouth of the container bottle 4. The cleaning assembly 22 cleans the bottle mouth of the container bottle 4 during the process of the capping assembly 21 rotating and fastening the cap 5 to the bottle mouth of the container bottle 4.

[0036] Understandably, existing aluminum capping devices for sealed plant-based beverages suffer from instability when fruit particles remain at the bottle opening. This application designs a device that effectively cleans residue from the bottle opening and stabilizes the capping process. The feeding mechanism 1 transports the container bottle 4 to the capping station, the clamping mechanism 3 secures the container bottle 4, and the capping assembly 21 of the capping mechanism 2 carries the cap 5 and screws it onto the bottle opening. Simultaneously, the cleaning assembly 22 cleans the bottle opening during the capping process. Specifically, the feeding mechanism 1 transports the container bottle 4 to the capping station, and the clamping mechanism 3 clamps and secures the container bottle 4; the capping assembly 21 carries the cap 5 down to the bottle opening, and the cleaning assembly 22 cleans the bottle opening; the capping assembly 21 screws the cap 5 onto the bottle opening, completing the capping operation. By incorporating the cleaning assembly 22, the bottle opening is cleaned before capping to remove residue, ensuring a clean bottle opening and thus improving the stability and sealing of the capping process.

[0037] Furthermore, the capping assembly 21 includes: a vertical linear motor 211, a first connecting plate 212, a rotary motor 213, a second connecting plate 214, a first cylinder, and a first clamping member 215. The first connecting plate 212 is connected to the moving end of the vertical linear motor 211, and the rotary motor 213 is connected to the first connecting plate 212. The vertical linear motor 211 drives the rotary motor 213 to move vertically up and down. The upper side of the second connecting plate 214 is connected to the rotary drive end of the rotary motor 213, and two first cylinders are connected to the second connecting plate 214. The two first cylinders are at the same distance from the central axis of the second connecting plate 214. The rotary motor 213 is used to drive the second connecting plate 214 to rotate around its central axis. There are two first clamping members 215, which correspond one-to-one with the first cylinders. The first clamping members 215 are connected to the telescopic end of the first cylinders. The two first clamping members 215 form a first clamping space for clamping the bottle cap 5. The two first cylinders are used to drive the two first clamping members 215 to move closer or further away from each other, so that the bottle cap 5 located in the first clamping space is clamped or released.

[0038] In this embodiment, a vertical linear motor 211 drives a rotary motor 213 to move vertically up and down, thereby moving the capping assembly 21 up and down. The rotary motor 213 drives a second connecting plate 214 to rotate around its central axis, thus rotating the capping assembly 21. A first cylinder drives first clamping members 215 to move closer or further apart, clamping or releasing the bottle cap 5. Through the cooperation of these structures, precise control and stable operation of the capping assembly 21 are achieved. In actual operation, the first cylinder drives the first clamping members 215 to clamp the bottle cap 5. Subsequently, the vertical linear motor 211 drives the capping assembly 21 to descend to the bottle opening, the rotary motor 213 rotates, and the bottle cap 5 is screwed onto the bottle opening. After capping, the first cylinder drives the first clamping members 215 to release the bottle cap 5, and the vertical linear motor 211 drives the capping assembly 21 to rise. Throughout the process, all components work together to ensure the stability and sealing of the capping.

[0039] Furthermore, the aluminum cap screwing device also includes a controller, and the screwing assembly 21 also includes a first sensor assembly. The controller is electrically connected to the first sensor assembly and the vertical linear motor 211, the rotary motor 213, and the first cylinder. The controller controls the vertical linear motor 211 and / or the rotary motor 213 and / or the first cylinder to work according to the feedback information of the first sensor assembly. The first sensor assembly includes a first sensor set at the screwing station for detecting the height of the cap 5, and / or a second sensor set on the side of the first clamping member 215 near the first clamping space for detecting the clamping pressure, and / or a third sensor set at the screwing station for detecting the rotational engagement state of the cap 5 and the container bottle 4.

[0040] Understandably, in actual operation, the first sensor detects the height of the cap 5, the second sensor detects the clamping pressure, and the third sensor detects the rotational engagement state of the cap 5 and the container bottle 4. Based on the feedback from these sensors, the controller controls parameters such as the lifting speed of the vertical linear motor 211, the rotational speed of the rotary motor 213, and the clamping force of the first cylinder. Throughout the process, all components work together to ensure the stability and sealing of the capping. Optionally, the first sensor can be a laser sensor, using a laser emitter and receiver to determine whether the cap 5 has reached the preset position. Optionally, the second sensor can be a pressure sensor. Optionally, the third sensor can be a CCD camera, which captures images of the mating structure of the cap 5 and the container bottle 4, allowing the controller to determine if the fit is tight.

[0041] Furthermore, the cleaning component 22 includes an air pump 221, a first vent 222, and a second vent 223. The air pump 221 is fixedly connected to the second connecting plate 214, the first vent 222 is fixedly connected to the second connecting plate 214, and the second vent 223 is movably connected to the second connecting plate 214 in a vertical direction. The second vent 223 is located on the side of the first vent 222 close to the central axis of the second connecting plate 214, and the side of the first vent 222 close to the central axis of the second connecting plate 214 is in contact with the second vent 223. The first vent 222 has a first air passage 2221, which has a first air inlet and a first air outlet. The first air inlet is connected to the exhaust end of the air pump 221, and the first air outlet is located on the side of the first vent 222 that is in contact with the second vent 223. The second vent 223 has multiple second air passages 2231. 31 has a second air inlet and a second air outlet. Multiple second air inlets of the second vent 223 are evenly distributed vertically on the side of the second vent 223 that is in contact with the first vent 222, and the distance between adjacent second air inlets is greater than the diameter of the first air outlet. Multiple second air outlets of the second vent 223 are evenly distributed vertically on the side of the second vent 223 facing the central axis of the second connecting plate 214. When the second vent 223 is vertically... When the direction is relative to the second connecting plate 214, the first air passage 2221 and the second air passage 2231 are connected or separated. When the first air passage 2221 and the second air passage 2231 are connected, the airflow output by the air pump 221 passes through the first air passage 2221 and the second air passage 2231 to the mouth of the container bottle 4. When the first air passage 2221 and the second air passage 2231 are separated, the airflow output by the air pump 221 is blocked at the first air outlet by the second venting member 223. The movable connection between the second venting member 223 and the second connecting plate 214 has multiple options, which are existing technologies and will not be described in detail here. Optionally, the second vent 223 is not directly connected to the second connecting plate 214. Instead, the second vent 223 is movably connected to the first vent 222, thereby indirectly achieving a movable connection with the second connecting plate 214. The connection between the second vent 223 and the first vent 222 can be achieved by opening a sliding groove on the first vent 222 and providing a sliding fit on the second vent 223. The sliding fit is slidably disposed in the sliding groove, so that the second vent 223 can move vertically relative to the first vent 222 and the second connecting plate 214.

[0042] It should be explained that the air pump 221 can provide clean airflow, and the air passage design of the first air passage 222 and the second air passage 223 allows the airflow to reach the bottle mouth of the container bottle 4; the second air passage 223 is movably connected to the second connecting plate 214 in the vertical direction, and the movement of the second air passage 223 realizes the connection or separation of the air passage. When the first air passage 2221 and the second air passage 2231 are connected, the airflow reaches the bottle mouth through the first air passage 2221 and the second air passage 2231 for cleaning; when the first air passage 2221 and the second air passage 2231 are separated, the airflow is blocked, thus realizing the efficient cleaning and reliable operation of the cleaning component 22.

[0043] Furthermore, the cleaning component 22 also includes an elastic element 224, which is disposed between the second vent 223 and the second connecting plate 214. Before the bottle cap 5 carried by the first clamping member 215 comes into contact with the container bottle 4 clamped and fixed by the clamping mechanism 3, the second vent 223 is separated from the clamping mechanism 3, the elastic element 224 is in a released state, and the first air passage 2221 and the second air passage 2231 are staggered. After the bottle cap 5 carried by the first clamping member 215 comes into contact with the container bottle 4 clamped and fixed by the clamping mechanism 3, the lower end of the second vent 223 comes into contact with the clamping mechanism 3, the elastic element 224 is in a compressed state, and the first air passage 2221 and the plurality of second air passages 2231 are sequentially connected.

[0044] Understandably, by adding an elastic element 224 to the cleaning assembly 22, the cleaning assembly 22 only begins to work after the cap 5 abuts against the container bottle 4, avoiding interference from airflow to the bottle opening before capping, thus improving the accuracy and reliability of cleaning. In actual operation, before the cap 5 abuts against the container bottle 4, the second vent 223 separates from the clamping mechanism 3, the elastic element 224 is in a released state, the first air passage 2221 and the second air passage 2231 are misaligned, and the airflow is blocked. At this time, the capping assembly 21 continues to descend until the cap 5 abuts against the container bottle 4. After the cap 5 abuts against the container bottle 4, the lower end of the second vent 223 abuts against the clamping mechanism 3, the elastic element 224 is compressed, and the first air passage 2221 and multiple second air passages 2231 are sequentially connected, and the airflow output by the air pump 221 reaches the bottle opening through the air passages for cleaning. During the cleaning process, the capping assembly 21 continues to operate, screwing the cap 5 onto the bottle opening to complete the capping operation. Throughout the process, the elastic element 224 enables the cleaning component 22 to automatically control the flow of air and block it, thereby improving the accuracy and reliability of the cleaning process.

[0045] Furthermore, the clamping mechanism 3 includes a second cylinder 31 and a second clamping member 32. There are two second cylinders 31 and two second clamping members 32, and each second cylinder 31 corresponds to a second clamping member 32. The second clamping member 32 is connected to the telescopic end of the second cylinder 31. The two second clamping members 32 form a second clamping space for clamping the container bottle 4. The two second cylinders 31 are used to drive the two second clamping members 32 to move closer or further away from each other, so that the container bottle 4 located in the second clamping space is clamped or released. After the bottle cap 5 carried by the first clamping member 215 abuts against the container bottle 4, the lower end of the second venting member 223 abuts against the second clamping member 32 directly below it.

[0046] In actual operation, when the container bottle 4 reaches the capping station, the second cylinder 31 drives the second clamping members 32 to move closer together and clamp the container bottle 4. During the capping process, the second clamping members 32 remain clamped to ensure the stability of the container bottle 4. After the capping is completed, the second cylinder 31 drives the second clamping members 32 to move away from each other, releasing the container bottle 4. Throughout the process, the stable clamping of the clamping mechanism 3 ensures the stability and sealing of the capping. In addition, the corresponding arrangement of the two second cylinders 31 and the second clamping members 32 allows the clamping mechanism 3 to clamp the container bottle 4 more evenly, further improving the stability of the clamping.

[0047] Specifically, the clamping mechanism 3 also includes a second sensor assembly. A controller is electrically connected to the second sensor assembly and the second cylinder 31. The controller controls the operation of the second cylinder 31 based on feedback information from the second sensor assembly. The second sensor assembly includes a fourth sensor located at the capping station to detect the position of the container bottle 4, and / or a fifth sensor located on the side of the second clamping member 32 near the second clamping space to detect clamping pressure. In actual operation, when the container bottle 4 reaches the capping station, the fourth sensor detects the position of the container bottle 4, and the fifth sensor detects the clamping pressure. The controller controls the clamping force and clamping time of the second cylinder 31 based on this information to ensure that the clamping mechanism 3 can accurately clamp the container bottle 4. During the capping process, the clamping mechanism 3 maintains a clamped state to ensure the stability of the container bottle 4. After capping is completed, the controller controls the second cylinder 31 to release the container bottle 4. Throughout the process, the coordinated use of the controller and the sensor assembly ensures the accuracy and reliability of the clamping process. Optionally, the fourth sensor can be a laser sensor or a CCD positioning detection camera. Optionally, the fifth sensor can be a pressure sensor.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
