Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery, in particular to a capping machine. Background Art

[0002] Chinese patent document CN 219259518 U discloses a stoppering device, wherein a cap sorting component conveys sorted bottle caps to a first cap-picking plate and a second cap-picking plate respectively through a first cap-feeding track and a second cap-feeding track, the two cap-picking plates are spaced apart, and a third cap-picking plate is coaxially arranged above a bottle-discharging dial wheel, the third cap-picking plate is docked with the second cap-picking plate, to ensure that the bottle caps output by the two tracks are consistent with the bottle-moving direction, so that it is convenient to take the bottle caps without affecting the bottle-moving speed; a cap pressing assembly comprises at least two cap-picking heads, which can take the bottle caps from the first cap-picking plate and the third cap-picking plate respectively during rotation, and finally the cap pressing assembly presses at least two bottle caps into corresponding bottle bodies synchronously, the structure is simple and reasonable, and it is conducive to improving production efficiency and reducing user production costs. The plugging device has three negative pressure capping heads installed on each mounting seat, and the three negative pressure capping heads share a vacuum channel, so that the three capping heads can synchronously absorb or release the bottle caps. Under normal circumstances, they can operate stably, but when there is no plug or no bottle without plugging (that is, some capping heads are missing plugs or some capping heads are missing bottles), they will interfere with each other, affecting the stability of the equipment and the product qualification rate. At the same time, each group of capping components is directly connected to the vacuum source, resulting in mutual influence between the capping components.

[0003] In addition, for soft aerosol packaging materials, a press cap is generally used for sealing. Due to its soft texture, if the bottle cap and the bottle body are not positioned accurately, it is easy to cause the bottle cap to be skewed, and the bottom of some types of bottles is not a flat structure and cannot stand upright, resulting in the inability to directly use the existing stoppering device for press capping.

[0035] Figures 1 to 11An embodiment of the capping machine of the utility model is shown. The capping machine of this embodiment includes a capping wheel 20 and m groups of liftable capping assemblies 21 arranged along the circumferential direction of the capping wheel 20. The capping assembly 21 includes n capping heads 211 with vacuum channels inside. The capping machine also includes an air separation mechanism 7. The air separation mechanism 7 is provided with m groups of joint assemblies 71. The joint assembly 71 includes n vacuum joints 711. The vacuum joints 711 are connected to the vacuum channels inside the capping heads 211 in a one-to-one correspondence, wherein m and n are not less than 2. In this embodiment, m=8, n=3. Specifically, three vacuum channels can be respectively provided inside the lifting rod 212, the mounting seat 213 and the cap removal head 211 and connected one by one. Three vacuum joints 711 are also provided on the lifting rod 212 and connected with the internal vacuum channels. The three vacuum joints 711 on the lifting rod 212 are connected one by one with the three vacuum joints 711 of the joint assembly 71 through pipe fittings. Preferably, the gas distribution groove assembly 721 is also provided to include three arc-shaped gas distribution grooves. Of course, in other embodiments, the number of vacuum joints 711 and vacuum channels can also be adjusted.

[0036] In the capping machine of this embodiment, 8 groups of liftable capping assemblies 21 correspond to 8 groups of joint assemblies 71 on the gas distribution mechanism 7, and 3 capping heads 211 of each group of capping assemblies 21 correspond to 3 vacuum joints 711 of each group of joint assemblies 71 and are connected one by one, so that the vacuum of each capping head 211 can be controlled individually. When there is no stopper or no bottle without a stopper, there will be no mutual interference, which is conducive to ensuring the stability of the equipment and the product qualification rate, and the structure is simple and reliable.

[0037] Furthermore, in the present embodiment, eight groups of joint assemblies 71 are arranged along the circumferential direction of the gas separation mechanism 7, and eight groups of pressure cover assemblies 21 are also arranged along the circumferential direction, which is beneficial for neatly distributing the pipelines between the joint assemblies 71 and the pressure cover assemblies 21. The three vacuum joints 711 of each group of joint assemblies 71 are arranged along the radial direction of the gas separation mechanism 7, which can make full use of the area on the gas separation mechanism 7, making the overall structure of the gas separation mechanism 7 compact and occupying less space.

[0038] Furthermore, in the present embodiment, the gas separation mechanism 7 comprises a gas separation seat 72 and a gas separation turntable 73 arranged on the gas separation seat 72, and the joint assembly 71 is arranged on the gas separation turntable 73.

The gas separation seat 72 is radially provided with three groups of gas groove assemblies 721, which are arranged one by one with the three vacuum joints 711 of each group of joint assemblies 71, and the gas separation groove assembly 721 includes three arc-shaped gas separation grooves and is arranged along the circumferential direction. For details, see Figure 7 The three vacuum joints 711 corresponding to the three arc-shaped gas grooves of the same group of gas groove components 721 belong to different joint components 71, so the mutual influence between the joint components 71 can be avoided, and the structure is simple and effective.

[0039] Furthermore, in this embodiment, a plurality of bottle body positioning grooves 201 and supporting grooves 202 for supporting the flange at the neck of the bottle are provided on the outer circumference of the capping thumbwheel 20. The bottle body positioning grooves 201 are used to position the bottle body 62 as a whole, so that the bottle body 62 is aligned with the bottle cap 61 above, and the supporting grooves 202 are used to support the flange at the neck of the bottle, so that the deformation of the bottle body can be reduced during capping, so that the bottle cap 61 can be smoothly pressed into the bottle body 62 with a relatively soft texture, and the structure is reasonable and effective.

[0040] As a preferred embodiment, a detachable supporting plate 203 is provided on the capping thumbwheel 20 (for example, a detachable connection is achieved by fasteners such as screws), and the supporting groove 202 is provided on the supporting plate 203. Compared with integrating the supporting groove 202 on the capping thumbwheel 20, it is convenient to replace the supporting plate 203, thereby adapting to bottles 62 of different specifications and reducing the workload of replacement.

[0041] Furthermore, in this embodiment, the capping wheel 20 is equipped with a bottle protection fence 204, and a limit plate 205 is provided on the bottle protection fence 204. The limit plate 205 can cooperate with the bottle body positioning groove 201 to limit the deformation and displacement of the bottle body 62 when the bottle cap 61 is pressed in, and can also cooperate with the supporting groove 202 so that the flange can be supported in the circumferential direction, reducing the deformation of the bottle body under stress, and the structure is simple and effective.

[0042] Furthermore, in the present embodiment, a bottle sorting component 11 (such as a bottle sorting bucket, etc.), a bottle conveying component 12 (such as a bottle conveying mesh belt, a bottle conveying track, etc.) and a bottle feeding dial wheel 1 are provided upstream of the capping dial wheel 20, a filling component 8 is provided on one side of the bottle conveying component 12, a bottle discharging dial wheel 3 is provided downstream of the capping dial wheel 20, a cap sorting component 4 (such as a cap sorting bucket) is provided on one side of the capping dial wheel 20, the cap sorting component 4 is provided with a first cap feeding track 41 and a second cap feeding track 42, the first cap feeding track 41 is connected to a first cap picking plate 51, the second cap feeding track 42 is connected to a second cap picking plate 52, a coaxially arranged third cap picking plate 53 is provided above the bottle discharging dial wheel 3, the third cap picking plate 53 is connected to the second cap picking plate 52, and the capping assembly 21 can take two bottle caps 61 from the first cap picking plate 51 and the third cap picking plate 53 respectively. The bottles 62 are arranged into two rows for output by the bottle sorting component 11 and then enter the bottle conveying component 12. When they are transferred to the filling component 8, the liquid medicine filling is completed and then they are transferred to the capping wheel 20 through the bottle feeding wheel 1. The cap sorting component 4 conveys the sorted bottle caps 61 to the first cap-picking plate 51 and the second cap-picking plate 52 respectively through the first cap-feeding track 41 and the second cap-feeding track 42, the pitch of the two cap-picking plates is pulled apart, and the third cap-picking plate 53 is coaxially arranged above the bottle-discharging dial 3, and the third cap-picking plate 53 is docked with the second cap-picking plate 52 to ensure that the bottle caps 61 output by the two tracks are consistent with the bottle moving direction, so that it is convenient to take the bottle caps 61 without affecting the bottle moving speed; the three cap-taking heads 211 of the capping assembly 21 can take the bottle caps 61 from the first cap-picking plate 51 and the third cap-picking plate 53 during the rotation process, and finally the capping assembly 21 presses the three bottle caps 61 into the corresponding bottle bodies 62 synchronously, which has a simple and reasonable structure and can greatly improve the production efficiency and reduce the production cost.

When the lifting rod 212 rotates with the rotating seat 23 and the capping dial wheel 20, the rolling member 214 at the lower end thereof rolls along the cam 22, thereby moving up and down, and the mounting seat 213 and each capping head 211 on the mounting seat 213 are synchronously lifted and lowered with the lifting rod 212. When each capping head 211 drops to a low position, the bottle cap 61 can be pressed into the bottle body 62, and the structure is simple and the pressing force is reliable.

[0044] Furthermore, in this embodiment, the cam 22, the first cover-shifting plate 51, the second cover-shifting plate 52 and the third cover-shifting plate 53 are respectively threadedly connected to an adjusting shaft 25, and the adjusting shaft 25 is provided with an adjusting sprocket 26, and the adjusting sprockets 26 are connected by chains (not shown in the figure).
