[0033] (Example 1)

[0034] like Figs. 1 to 3 The octagonal enclosure forming and gripping mechanism shown includes a base plate 1 and a middle plate 2 arranged coaxially and in parallel. The base plate 1 is fixedly mounted, and four sets of support plate assemblies 3 are evenly arranged circumferentially at the end away from the middle plate 2. Each set of support plate assemblies 3 is slidably connected to the base plate 1 along the radial direction of the base plate, and a suction plate assembly 4 is provided on it for adsorbing the octagonal enclosure. The middle plate 2 is movably mounted along the axial direction of the base plate. Each set of support plate assemblies 3 is hinged to the outer circumferential surface of the middle plate 2 with a swing rod 5. The axial movement of the middle plate 2 drives the swing rod to swing, thereby pushing the support plate assembly 3 closer to or away from the center of the middle plate, realizing the opening and forming of the octagonal enclosure.

[0035] Specifically, a top plate 6 is provided parallel to the top of the intermediate plate 2. Reinforcing rods 8 are vertically fixed to the bottom plate 1 around the perimeter of the top plate 6, thus securing it to the bottom plate 1. A top support cylinder 7 is fixedly mounted at the center of the top plate 6. The piston rod of the top support cylinder 7 is vertically downward and connected to the intermediate plate 2. The extension and retraction of the top support cylinder 7 drives the intermediate plate 2 to move axially along the bottom plate 1. To improve the stability of the axial movement, this embodiment includes multiple guide rod assemblies 9 vertically connected between the intermediate plate 2 and the top plate. These guide rods provide direction for the axial movement of the intermediate plate 2, ensuring it moves in a straight line and preventing deviation or rotation. This improves the overall system's operational accuracy and supports the weight of the intermediate plate as a moving component, helping to distribute the load and reduce pressure on other components. To further reduce the load, this embodiment includes multiple weight-reducing holes 2-1 evenly distributed on the intermediate plate 2, thereby reducing the weight of the intermediate plate 2, lowering the load, and extending the service life of the top support cylinder 7.

[0036] The bottom of the base plate 1 is provided with a linear guide rail assembly 10 corresponding to the support plate assembly 3. The slider of the linear guide rail assembly 10 is fixedly connected to the base plate 1, and the guide rail is fixedly connected to the support plate assembly 3, thereby realizing the sliding connection between the support plate assembly 3 and the base plate 1. Two sets of linear guide rail assemblies 10 are arranged in parallel at the bottom connection between each set of support plate assembly 3 and the base plate 1. This improves the load capacity and helps maintain better parallelism and straightness, avoiding uneven sliding force on the support plate assembly 3 that may occur under certain conditions, thus preventing excessive local wear of the guide rail and extending its service life.

In order to reduce the weight of the support plate assembly 3, the T-shaped support frame of the embodiment is made of aluminum alloy profile, which not only has light weight, but also has better overall structural strength and support performance. In addition, a plurality of reinforcing plates 3-4 are arranged on the rear side of the support plate 3-3 in parallel, so that the structural strength of the support plate 3-3 is improved, the support plate 3-3 is prevented from being deformed under pressure in the process of opening the octagonal cover, and the forming effect of the octagonal cover is affected.

[0038] A through hole is arranged on the support plate 3-3, the suction plate assembly 4 comprises a suction plate air cylinder 4-1 fixedly connected to the rear side of the support plate 3-3, a connecting plate 4-2 and a vacuum suction nozzle 4-3 are vertically and fixedly connected to the end of the piston rod of the suction plate air cylinder 4-1 in sequence, the vacuum suction nozzle 4-3 is opposite to the through hole, and under the driving of the suction plate air cylinder 4-1, the vacuum suction nozzle 4-3 is translated to the other side of the through hole and is in contact with the inner side of the octagonal cover, so that the vacuum suction is realized, the automatic grabbing is completed, the suction plate assembly 4 is installed on the existing mechanical arm, the suction plate assembly 4 is convenient to transfer, the overall structure is simple, and the grabbing efficiency is high.

[0039] The working process of the embodiment is as follows:

[0040] In the initial state, when the supporting air cylinder 7 is retracted, the support plate 3-3 is in the retracted state, and the vacuum suction nozzle 4-3 does not expose the support plate 3-3.

[0041] When working, after the octagonal cover is pre-opened by a certain distance by manual operation or a previous device, the structure of the embodiment is deep into the cover. When the supporting air cylinder 7 is extended, the middle plate 2 is driven to move, the swing lever 5 drives the sliding seat 3-1 to move outward, so that the eight support plates 3-3 are synchronously extended outward. The support plate 3-3 is synchronously supported outward until the support plate 3-3 is supported to the inner wall of the octagonal cover, so that the octagonal cover is formed into an octagonal shape, and the opening and forming are completed. At this time, the suction plate air cylinder 4-1 drives the vacuum suction nozzle 4-3 to extend and suck the inner side of the octagonal cover, so that the octagonal cover is grabbed by the suction force and the supporting force, and the automatic grabbing is realized.

[0042] The utility model is used for being placed in the pre-opened octagonal cover, the swing lever 5 is driven to move through the liftable middle plate 2, then four groups of support plate assemblies 3 installed on the bottom plate 1 and sliding along the radial direction are driven to approach each other and separate, so that the octagonal cover is completely opened and formed, the inner side of the octagonal cover is adsorbed through the suction plate assembly 4, the automatic grabbing is realized, the suction plate assembly 4 is convenient to transfer, the suction plate assembly 4 can be matched with the subsequent station of the automatic packaging line, and the packaging efficiency is improved.
