Description
Technical Field
[0001] The utility model relates to the technical field of container conveying equipment, in particular to a container clamping device for grabbing containers. Background Art
[0002] Container clamping devices come in two types: active and passive. The passive container clamping device comprises a pair of clips hingedly connected to a base. Each clip comprises a clamping side plate and a driving side plate, located on either side of the hinged connection to the base. Each clamping side plate has a clamping portion for gripping the container's mouth provided on the inner side of its outer end. A spring is provided between the pair of clamping side plates, causing the clamping portions of the clips to constantly move toward each other, thereby gripping the container.
[0003] Liquid packaging market demands are driving increasing product differentiation, with different container sizes having varying calibers. Switching between different product sizes requires replacing all the container gripping devices used to hold the container mouths on the entire blow-fill-cap system. This requires ensuring that the gripping centers remain unchanged after replacement, thereby maintaining the same container handover position. The numerous and complex gripping devices in the entire blow-fill-cap system make disassembly, installation, and commissioning time-consuming and labor-intensive, resulting in significant downtime, disrupting production, and increasing filling costs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a compatible passive container clamping device, which is suitable for clamping containers with different calibers.
[0005] To solve the above problems, the technical solution adopted by the present invention is: a compatible passive container clamping device, including: a pair of clips hingedly connected to the base, each clip including a clamping side plate and a driving side plate, the clamping side plate and the driving side plate of each clip are respectively located on both sides of the hinged position with the base, a clip groove is provided on the inner side of each clamping side plate, a clip clamping portion is provided on the inner side of the clip at the outer end position of the clip groove, a first elastic component is provided between the pair of driving side plates, a clip limiting mechanism is provided on the base outside each driving side plate, and a slider is also movably provided on the base between the pair of clips, the slider including a slider body, a slider clamping portion is provided on the head of the slider body, the slider clamping portion is located on the side close to the clip clamping portion, and the tail of the slider body is connected to the slider driving rod.
[0006] It also includes a slider limiting mechanism, which enables the slider to have a maximum distance position for moving toward the clip clamping part and a maximum distance position for moving away from the clip clamping part. The slider driving rod can drive the entire slider to move back and forth between the maximum distance position for moving toward the clip clamping part and the maximum distance position for moving away from the clip clamping part. A second elastic component is provided between the slider driving rod and the base.
[0007] In the initial state, a pair of driving side plates are opened outwards under the action of the first elastic component and are respectively blocked by the clip limiting mechanisms, which makes the pair of clip clamping parts approach each other to the position with the minimum spacing, and the slider is limited by the slider limiting mechanism at the maximum distance position moving toward the clip clamping part under the action of the second elastic component.
[0008] The mouth of the first caliber container can squeeze the pair of clip clamping parts in the initial state, causing them to open outward and causing the pair of driving side plates to move closer to each other and respectively disengage from the clip limiting mechanisms, thereby entering the inner sides of the pair of clip clamping parts. When the maximum width position of the mouth of the first caliber container enters the inner sides of the pair of clip clamping parts, the driving side plates will open outward and reset. At this time, the elastic force of the first elastic component can prompt the pair of clip clamping parts to drive the mouth of the first caliber container to move further inward and rest against the slider clamping part, and push the slider to move away from the pair of clip clamping parts until the driving side plate moves outward and is blocked by the clip limiting mechanism and is completely reset. At this time, the mouth of the first caliber container moves into place and is clamped by the pair of clip clamping parts and the slider clamping part.

When the maximum width position of the mouth of the second caliber container enters the inner sides of the pair of clip clamping parts, the driving side plates will open outward and reset. At this time, the elastic force of the first elastic component can prompt the pair of clip clamping parts to drive the mouth of the second caliber container to move further inward and rest against the slider clamping part, and push the slider to move in the direction away from the pair of clip clamping parts until the slider moves to the maximum distance position moving away from the clip clamping part. At this time, the mouth of the second caliber container moves into place and is clamped by the pair of clip clamping parts and the slider clamping part.
[0010] The mouth diameter of the first caliber container is smaller than the mouth diameter of the second caliber container; the mouth of the first caliber container is in a clamping state and the mouth of the second caliber container is in a clamping state, and the positions of the clamping centers of a pair of clip clamping parts and the slider clamping parts in these two clamping states are the same.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.
[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the compatible passive container clamping device includes: a pair of clamps 1 respectively hinged to the base 2, each clamp 1 includes a clamping side plate 11 and a driving side plate 12, and the clamping side plate 11 and the driving side plate 12 of each clamp 1 are respectively located on both sides of the hinge position with the base 2.
[0026] Specifically, the hinged connection structure between each clip 1 and base 2 includes a cylindrical nut 101. The cylindrical body 102 of the cylindrical nut 101 is inserted through the clip mounting hole 106 on the clip 1, the mounting sleeve 104, and the base mounting hole 201 on the base 2. A bearing 105 is also provided between the cylindrical body 102 of the cylindrical nut 101 and the clip mounting hole 106, and the mounting sleeve 104 is located between the bearing 105 and the base 2. A gasket 107 and a wear-resistant washer 108 are provided between the cap body 103 of the cylindrical nut 101 and the clip 1. A stud 109 is blocked on the base 2 and threadedly fastened to the cylindrical body 102 of the cylindrical nut 101.
[0027] Each clamping side plate 11 has a clip groove 111 disposed on its inner side to accommodate the container mouth. A clip clamping portion 112 is disposed on the inner side of the clip 1 at the outer end of the clip groove 111. In this embodiment, the outer ends 113 of the pair of clamping side plates 11 are shaped like a flared mouth, guiding the container mouth toward the pair of clip clamping portions 112.
[0028] A first elastic component is disposed between the pair of drive side plates 12. In this embodiment, the first elastic component is a first compression spring 3. A first spring mounting seat 31 is disposed on the inner side of the outer end portion of each drive side plate 12. The two ends of the first compression spring 3 are respectively mounted on the first spring mounting seats 31 of the pair of drive side plates 12. A clip limiting mechanism is disposed on the base 2 outside each drive side plate 12. In this embodiment, the clip limiting mechanism on the base 2 outside each drive side plate 12 is a limiting post 21 fixedly mounted on the base 2.
[0029] A slider 4 is movably provided on the base 2 between a pair of clips 1. The slider 4 includes a slider body 41. A slider clamping portion 42 is provided at the head of the slider body 41. The slider clamping portion 42 is located on a side close to the clip clamping portion 112. The tail of the slider body 41 is connected to a slider driving rod 43.
[0030] The slider also includes a slider limiting mechanism that allows the slider 4 to have a maximum distance position toward the clip clamping portion 112 and a maximum distance position away from the clip clamping portion. The slider driving rod 43 can drive the entire slider 4 to translate back and forth between the maximum distance position toward the clip clamping portion 112 and the maximum distance position away from the clip clamping portion 112. In this embodiment, the base 2 is provided with a guide groove 23, and the slider driving rod 43 is located within the guide groove 23.
[0031] A second elastic component is disposed between the slider drive rod 43 and the base 2. In this embodiment, the second elastic component is a second compression spring 5. A second spring mounting seat 431 is disposed on the slider drive rod 43. The two ends of the second compression spring 5 are respectively engaged with the second spring mounting seat 431 and the base mounting block 22 fixedly disposed at the end of the base 2.
[0032] The structure of the slider limiting mechanism includes: a slider slot 411 is provided at the top of the slider body 41, with first and second retaining surfaces 412 and 413 formed on both end surfaces of the slider slot 411, respectively. The gasket 107 and the wear-resistant washer 108 are located within the slider slot 411. Under the action of the second elastic component, the second retaining surface 413 of the slider slot 411 is retained by the gasket 107 and the wear-resistant washer 108, at which point the slider 4 is positioned at its maximum distance, toward the clip clamping portion 112. Under the action of an external force, the first retaining surface 412 of the slider slot 411 is retained by the gasket 107 and the wear-resistant washer 108, at which point the slider 4 is positioned at its maximum distance, away from the clip clamping portion 112.
[0033] In the initial state, a pair of driving side plates 12 are opened outward under the action of the first compression spring 3 and are respectively blocked by the clip limiting mechanism, that is, the limiting column 21, which makes the pair of clip clamping parts 112 approach each other to the position with the minimum distance. The slider 4 is limited by the slider limiting mechanism at the closest position relative to the clip clamping part 112 under the action of the second compression spring 5, that is, the second blocking surface 413 of the slider slot 411 is blocked by the gasket 107 and the wear-resistant washer 108. In this state, the slider 4 is located at the maximum distance position moving towards the clip clamping part 112.
[0034] like Figure 3 As shown, the mouth of the first caliber container 6 can squeeze the pair of clip clamping parts 112 in the initial state, causing it to open outward and causing the pair of driving side plates 12 to move closer to each other and separate from the limiting columns 21, thereby entering the inner side of the pair of clip clamping parts 112. When the maximum width position of the mouth of the first caliber container 6 enters the inner side of the pair of clip clamping parts 112, the driving side plate 12 will open outward and reset. At this time, the elastic force of the first compression spring 3 can prompt the pair of clip clamping parts 112 to drive the mouth of the first caliber container 6 to move further inward and abut against the slider clamping part 42, and push the slider 4 to move away from the pair of clip clamping parts 112 until the driving side plate 12 moves outward and is blocked by the limiting column 21 and is completely reset. At this time, the mouth of the first caliber container 6 moves into place and is clamped by the pair of clip clamping parts 112 and the slider clamping part 42.
[0035] like Figure 4As shown, the mouth of the second caliber container 7 can squeeze the pair of clip clamping parts 112 in the initial state, causing them to open outward and causing the pair of driving side plates 12 to move closer to each other and respectively detach from the clip limiting columns 21, thereby entering the inner side of the pair of clip clamping parts 112. When the maximum width position of the mouth of the second caliber container 7 enters the inner side of the pair of clip clamping parts 112, the driving side plate 12 will open outward and reset. At this time, the elastic force of the first compression spring 3 can prompt the pair of clip clamping parts 112 to drive the mouth of the second caliber container 7 to move further inward and rest on the slider clamping part 42, and push the slider 4 to move in the direction away from the pair of clip clamping parts 112, until the slider 4 moves to the maximum distance position away from the clip clamping part 112, that is, the position where the first blocking surface 412 of the slider slot 411 is blocked by the gasket 107 and the wear-resistant washer 108. At this time, the mouth of the second-caliber container 7 moves into position and is clamped by the pair of clip clamping parts 112 and the slider clamping part 42 .
[0036] The diameter of the mouth of the first-caliber container 6 is smaller than the diameter of the mouth of the second-caliber container 7. The mouth of the first-caliber container 6 is in a clamped state, and the mouth of the second-caliber container 7 is in a clamped state. In both clamped states, the position of the clamping center O of the pair of clip clamping portions 112 and the slider clamping portion 42 is the same.
[0037] It can be seen that the compatible passive container clamping device has a greatly simplified structure and is compatible with containers of two caliber models. The clamping center positions of the two caliber models of containers are the same. Therefore, the adaptability of the container clamping device is greatly improved, and the frequent replacement of the clamping device can be effectively avoided, thereby effectively saving the production cost of filling production.
