The structure is simple, the installation is convenient, and the practicability is strong.

[0050] like Figure 1 As shown, a bearing 220 is installed on the cross bar 22 , and the bearing 220 is located in the slide groove 23 .

[0051] The bearing 220 replaces the cross bar 22 in contact with the slide groove 23, thereby converting the sliding friction between the cross bar 22 and the slide groove 23 into rolling friction between the bearing 220 and the frame, thereby reducing friction resistance and extending service life, and having strong practicality.

[0052] There are multiple lifting rods 2, and a first transmission mechanism is provided between each lifting rod 2 and the rotating shaft 1.

[0053] The multiple lifting rods 2 are used to simultaneously suck the piles of trademark papers 70 in the multiple paper storage bins 7, thereby improving the work efficiency and having strong practicality.

[0054] Both sides of the guide rail 61 are provided with V-shaped guide grooves; A slide 63 is mounted on the frame, and V-shaped rollers 630 are rotatably mounted on both sides of the guide rail 61. The V-shaped rollers 630 are located in the V-shaped guide grooves. There are at least three V-shaped rollers 630 , and each V-shaped guide groove has at least one V-shaped roller 630 .

[0055] In fact, according to actual conditions, a guide rail 61 with a rectangular cross-section can be used to cooperate with the rectangular through hole opened on the frame to achieve the vertical sliding installation of the guide rail 61. This embodiment completes the vertical sliding installation of the guide rail 61 and the frame through the cooperation between the guide rail 61 and the V-shaped roller 630. It has a simple structure, is easy to install, and is highly practical.

[0056] A filter 45 is installed on the connecting pipe 420 .

[0057] The external air sucked into the connecting pipe 420 through the suction cup 41 is filtered by the filter 45 to prevent dust in the air from entering the suction mechanism through the connecting pipe 420, which is highly practical.

[0058] In this embodiment, when in use, the external mechanism drives the rotating shaft 1 to rotate, thereby driving the first cam plate 3 and the second cam plate 6 to rotate; During the rotation of the first cam plate 3, the lifting rod 2 is driven to move up and down through the first transmission mechanism; During the rotation of the second cam plate 6, the rod body 53 is driven to reciprocate through the second transmission mechanism; When the lifting rod 2 rises to the point where the suction cup 41 contacts the trademark paper 70 in the paper bank 7, the piston 51 is located at the first position, the air suction pipe 42 is connected to the connecting pipe 420 via the cylinder 52, and the free end of the cylinder 52 is blocked. At this time, the suction cup 41 is in a negative pressure state under the action of the connecting pipe 420, and the trademark paper 70 in the paper bank 7 is adsorbed; After the adsorption is completed, the lifting rod 2 moves downward, and drives the adsorbed trademark paper 70 to move downward through the suction cup 41, so that the trademark paper 70 is separated from the paper bank 7, until the trademark paper 70 reaches the box mold conveyor belt 71. At this time, the piston 51 moves downward to the second position, blocks the air suction pipe 42, and makes the connecting pipe 420 communicate with the atmosphere through the free end of the cylinder 52, the negative pressure state in the suction cup 41 is destroyed, and the suction cup 41 no longer adsorbs the trademark paper 70; At the same time, after the adsorption is completed and before the through pipe 420 is connected to the atmosphere through the free end of the cylinder 52, the piston 51 blocks the air suction pipe 42; When the suction cup 41 no longer forms suction on the trademark paper 70, the suction cup 41 is driven by the lifting rod 2 to fall below the box mold conveyor belt 71, and the trademark paper 70 is located on the box mold conveyor belt 71, and the box mold conveyor belt 71 drives the trademark paper 70 to move to the next station; When the box mold conveyor belt 71 drives the trademark paper 70 to leave from directly above the suction cup 41, the lifting rod 2 moves upward again under the action of the transmission assembly, and before the piston 51 moves to the first position, so that the suction pipe 42 is connected with the connecting pipe 420 through the cylinder 52, the piston 51 blocks the suction pipe 42 again until the lifting rod 2 rises to the suction cup 41 and contacts the trademark paper 70 in the paper library 7, and the suction pipe 42 is connected with the connecting pipe 420 through the cylinder 52, and the trademark paper 70 in the paper library 7 is adsorbed for the second time.

The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
