DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 8 As shown, the utility model provides a suction device with a single-sheet material taking function, including a mounting bracket 1, the inner wall of the mounting bracket 1 is provided with two groups of friction brackets 2, the front end of the friction bracket 2 is hinged with a first cylinder 3, the output end of the first cylinder 3 is hinged with a first connecting rod 4, the bottom end of the first connecting rod 4 is hinged with a second connecting rod 5, the front end of the friction bracket 2 is hinged with two groups of second connecting rods 5, the front end of the second connecting rod 5 is provided with a disassembly structure 7, and the front end of the disassembly structure 7 is provided with a friction wheel 6.

[0027] By adopting the above scheme: by starting the first cylinder 3, the first connecting rod 4 and the second connecting rod 5 hinged to the output end of the first cylinder 3 can be driven by the first cylinder 3 to drive the position of the second connecting rod 5 and the hinge of the friction bracket 2 to rotate, thereby driving the disassembly and assembly structure 7 and the friction wheel 6 installed on the second connecting rod 5 to change the angle, so that they can contact the plate.

[0028] like Figures 1 to 8As shown, the disassembly and assembly structure 7 includes a connecting block 701, a limit block 702 and a limit ring 703. The connecting block 701 is fixed at the front end of the second connecting rod 5. The limit block 702 is fixed inside the connecting block 701. The limit ring 703 is arranged at the front end of the limit block 702. The inner wall of the connecting block 701 is provided with an internal thread, and the outer wall of the bottom end of the limit ring 703 is provided with an internal thread. The connecting block 701 and the limit ring 703 are arranged to be threadedly connected. The inner wall of the limit ring 703 is close to the outer wall of the fixed plug rod 704. The center of the limit ring 703 is provided with a socket. The outer wall of the fixed plug rod 704 fits the inner wall of the limit ring 703. The front end of the fixed plug rod 704 is fixed with a connecting plate 705. The limit block 702 is provided with four groups arranged at equal intervals about the central axis of the connecting block 701, and the side end of the connecting plate 705 is rotatably connected to the friction wheel 6.

[0029] The above scheme is adopted: by fixing the connecting block 701 at the front end of the second connecting rod 5, the shape of the limit block 702 inside the connecting block 701 can be retracted inward after the top end contacts the bottom end of the limit ring 703, and the fixed plug rod 704 is inserted into the grooves of the limit ring 703 and the limit block 702, at this time, rotating the limit ring 703 can fix the limit ring 703 to the inside of the connecting block 701 through the thread of the outer wall of the limit ring 703, and at this time, the limit block 702 can be squeezed, so that the limit block 702 shrinks, so that its inner wall contacts the outer wall of the fixed plug rod 704, and then the fixed plug rod 704 is firmly fixed to the inside of the connecting block 701 by tightening the limit ring 703, and when disassembling, it is only necessary to reversely rotate the limit ring 703 and the limit block 702 will rebound, so that the fixed plug rod 704 can be detached, so as to facilitate the quick disassembly and replacement of the fixed plug rod 704 and the connecting plate 705 and the friction wheel 6 fixed at one end of the fixed plug rod 704.

[0030] like Figures 1 to 8 As shown, four groups of connecting brackets 8 are evenly spaced on the side wall of the mounting bracket 1, an air blowing pipe 9 is fixed to the inner wall of the connecting bracket 8, two groups of supporting brackets 10 are fixed to the inner wall of the mounting bracket 1, a second cylinder 11 is fixed to the top of the supporting bracket 10, a first suction cup 12 is provided at the bottom output end of the second cylinder 11, a second suction cup 13 is fixed to the bottom end of the mounting bracket 1, and a plurality of groups of the second suction cups 13 are arranged at equal intervals about the central axis of the mounting bracket 1.

[0031] By adopting the above solution, air can be blown onto the plate through the air blowing pipe 9, and when the second air cylinder 11 is started, the first suction cup 12 installed at the bottom can be pushed to make it contact the plate.

[0032] The working principle and use process of the utility model are as follows: by starting the first cylinder 3, the first connecting rod 4 and the second connecting rod 5 hinged to the output end of the first cylinder 3 can be driven by the first cylinder 3 to drive the second connecting rod 5 to rotate at the hinge of the friction bracket 2, thereby driving the disassembly structure 7 and the friction wheel 6 installed on the second connecting rod 5 to change the angle, so that the plate can be contacted. When sucking a single sheet of a medium-thick plate stack, the second suction cup 13 is dropped above the plate stack, the second cylinder 11 pushes the first suction cup 12 to suck and lift the plate, and the air blowing pipe 9 is lifted. The second suction cup 13 starts to suck the plates after the set time is reached, so as to achieve the purpose of separating and sucking single plates of medium and thick specifications. For thin plate stacks, after the device is in place as a whole, the friction wheel 6 is pressed down by the operation of the first cylinder 3, and the mounting bracket 1 moves forward as a whole within the set time. After the friction force of the friction wheel 6 makes the top plate of the plate stack move forward by a set value, the friction wheel 6 is lifted and separated from the contact with the plate, and then the second cylinder 11 pushes the first suction cup 12 to press down except the top remaining plate stack, and the remaining second suction cups 13 start to suck the plates, so as to achieve the effect of separating and sucking single thin plates.
