[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a grabbing device for grabbing a can, wherein the upper outer side of the can has an annular protrusion. The grabbing device comprises a fixed base 1, a moving assembly, a grabbing frame 10, a first grabbing assembly, a second grabbing assembly and a driving assembly 11.

[0023] like Figure 3 As shown, the shape of the can is roughly cylindrical, and the can is used for filling the solution.

[0024] like Figure 1 As shown, the moving assembly is arranged on the fixed base 1. The grabbing frame 10 is fixed on the moving assembly and is used to move under the drive of the moving assembly.

[0025] The moving assembly is used to connect the fixed base 1 and the grabbing frame 10, and drive the grabbing frame 10 to move, thereby driving the components on the grabbing frame 10 to move.

[0026] like Figure 1 As shown, the first grabbing assembly includes two grabbing claws 14 arranged opposite to each other, and both grabbing claws 14 are hinged to the grabbing frame 10; the shape of the two grabbing claws 14 after being assembled is adapted to the shape of the outer surface of the can. The second grabbing assembly is located below the first grabbing assembly and is located on the same side of the grabbing frame 10 as the first grabbing assembly. The second grabbing assembly includes two auxiliary claws 15 arranged opposite to each other, and both auxiliary claws 15 are hinged to the grabbing frame 10; the shape of the two auxiliary claws 15 after being assembled is adapted to the shape of the outer surface of the can. The driving assembly 11 is used to drive the two grabbing claws 14 to open and close. After the driving assembly 11 drives the two grabbing claws 14 to close, the upper surface of the grabbing claws 14 abuts against the lower surface of the annular protrusion of the can.

[0027] The shape of the two gripping claws 14 after being assembled is adapted to the shape of the outer surface of the can, so the two gripping claws 14 can be completely in contact with the outer surface of the can after being assembled, that is, the gripping claws 14 are in surface contact with the outer surface of the can. Similarly, the auxiliary claws 15 are also in surface contact with the outer surface of the can.

[0028] The upper surface of the grabbing claw 14 abuts against the lower surface of the annular protrusion of the can, which can reduce the shaking of the can after the grabbing device grabs the can.

[0029] Through the above arrangement, after the driving component 11 drives the two grabbing claws 14 to open, the moving component can move the first grabbing component and the second grabbing component to the position of the barrel by driving the grabbing frame 10, and then the driving component 11 drives the two grabbing claws 14 to close, and the two grabbing claws 14 can grab the barrel, because the shape of the two grabbing claws 14 after splicing is adapted to the shape of the outer surface of the barrel, and the grabbing claws 14 and the barrel are in surface contact, and there are more force points, so the stability of the two grabbing claws 14 when grabbing the barrel can be improved, and the safety risk can be reduced; and the upper surface of the grabbing claw 14 abuts against the lower surface of the annular protrusion of the barrel, which can reduce the shaking of the barrel after the grabbing device grabs the barrel. In this process, the two auxiliary claws 15 of the second grabbing component can also be closed, so that the two auxiliary claws 15 can limit the lower part of the barrel, so that the grabbing device remains stable during the moving process of the barrel, reducing the shaking of the barrel, and further improving the stability of the grabbing device when grabbing the barrel. The moving assembly can drive the barrel to move to the desired location through the first grabbing assembly and the second grabbing assembly on the grabbing frame 10, thereby eliminating the need to manually move the barrel, thereby reducing the labor intensity when transporting the barrel.

[0030] Therefore, the grabbing device provided by the embodiment of the utility model is provided with a first grabbing assembly and a second grabbing assembly on the grabbing frame 10, and the shape of the two grabbing claws 14 of the first grabbing assembly after being assembled is adapted to the shape of the outer surface of the can. After the driving assembly 11 is used to drive the two grabbing claws 14 to close, the grabbing claws 14 can be in surface contact with the can, with more force points, thereby improving the stability of the two grabbing claws 14 when grabbing the can and reducing safety risks; by making the upper surface of the grabbing claws 14 abut against the lower surface of the annular protrusion of the can, the shaking of the can can be reduced after the grabbing device grabs the can. Moreover, after the auxiliary claw 15 is closed, the lower part of the can can be limited, further improving the stability of the grabbing device when grabbing the can. By providing a moving assembly, the can can can be driven to move to the desired placement position by the first grabbing assembly and the second grabbing assembly on the grabbing frame 10, without the need to manually transfer the can, thereby reducing the labor intensity when transferring the can.

[0031] In some embodiments, Figure 3 and Figure 4 As shown, the outer side of the upper portion of the can has an annular protrusion, and the upper surface of the grab claw 14 has a plurality of protrusions arranged in an annular shape.

[0032] Exemplarily, the protrusions on the upper surface of the grab claw 14 are tooth-shaped protrusions.

[0033] Through the above-mentioned arrangement, the friction between the upper surface of the grabbing claw 14 and the lower surface of the annular protrusion of the can barrel can be increased, so that the grabbing claw 14 and the annular protrusion of the can barrel can be more firmly combined after contact, further reducing the shaking of the can barrel and improving the stability of the grabbing device when grabbing the can barrel.

[0034] In some embodiments, Figure 5 As shown, a flexible pad 16 is provided on the inner side of the auxiliary claw 15 .

[0035] For example, the material of the flexible gasket 16 may include rubber. Figure 5 As shown, the flexible gasket 16 is fixed to the inner side of the auxiliary claw 15 by four countersunk bolts 17 .

[0036] The flexible gasket 16 has a large friction coefficient, which can increase the friction between the auxiliary claw 15 and the outer wall of the can, so that the auxiliary claw 15 can better ensure the stability of the can; and the flexible gasket 16 has a large elasticity, which can reduce the wear of the can caused by the collision between the auxiliary claw 15 and the can.

[0044] Exemplarily, the reinforcing bracket 13 is connected to the grabbing arm 12 and the auxiliary arm 18 on the same side by welding.

[0045] This can increase the load-bearing capacity of the grabbing arm 12 and ensure that the grabbing claw 14 and the auxiliary claw 15 on the same side can move synchronously.

[0050] Through the above arrangement, the position of the grabbing frame 10 can be flexibly adjusted, so that the grabbing device can grab the cans and barrels, and the cans and barrels can be moved to a suitable position after the grabbing device grabs the cans and barrels.

[0051] In some embodiments, Figure 1As shown, the rotating assembly 20 includes a rotating platform 2 and a support frame 4. The rotating platform 2 is sleeved inside the fixed base 1.

[0053] Exemplarily, the bottom of the support frame 4 has a connecting plate 3 , which is fixed to the rotating platform 2 by bolts 19 .

[0054] Through the above arrangement, the components on the lifting assembly 21 can be driven to rotate together by the rotating table 2.

[0055] In some embodiments, Figure 1 As shown, the lifting assembly 21 includes a lifting frame 5 and a third driving member 6.
