The vacuum suction cup 4 is used to adsorb the label. The sponge pressure plate 1 is used to press the label onto irregularly shaped items after labeling.

[0038] The base 6 of the labeling mechanism is slidably mounted on the linear guide rail 23. The linear guide rail 23 guides the up-and-down movement of the labeling mechanism.

[0039] The lifting cylinder 25 is mounted on the adjusting plate assembly via the lifting cylinder mounting plate 14. Specifically, the lifting cylinder mounting plate 14 is fixed on the adjusting plate 15, and the upper end of the lifting cylinder mounting plate 14 is provided with a lifting cylinder fixing plate 12, on which the lifting cylinder 25 is mounted.

[0042] The lifting cylinder 25, the tilting cylinder 26, the telescopic cylinder 27, and the magnetic switch sensor 30 communicate with the controller. The magnetic switch sensor 30 is used to detect whether the vacuum suction cup 4 or the sponge pressure plate 1 is in contact with the item. When the vacuum suction cup 4 or the sponge pressure plate 1 is in contact with the item, it feeds back a contact signal to the controller. The controller then controls the lifting cylinder 25 to lift upwards based on the received contact signal, thereby driving the labeling mechanism to move upwards.

[0043] A drag chain 21 is mounted on the linear guide rail 23 via a drag chain mounting plate 3. The drag chain mounting plate 3 has a wire groove, and the drag chain 21 is used to accommodate the cables or pipes of the labeling device.

[0044] Please see Figure 6 The labeling device of the present invention, adaptable to various shapes of items, is installed next to the label printer 100. When a flat or square item needs labeling, the workflow is as follows: The telescopic cylinder 27 extends the vacuum suction cup 4 near the label peeling mechanism of the label printer 100. After the label printer prints and peels off the label, the vacuum suction cup 4 picks up the label. Simultaneously, the air pipe 18 blows high-pressure gas to better adhere the label to the vacuum suction cup 4. Then, the telescopic cylinder 27 retracts the vacuum suction cup 4, and the air pipe 18 stops blowing gas. The lifting cylinder 25 moves the labeling mechanism downwards along the linear guide rail 23, allowing the vacuum suction cup 4 to affix the label to the flat or square item. When the magnetic switch sensor 30 detects that the vacuum suction cup 4 has contacted the item, the magnetic switch sensor 30 sends a contact signal to the controller. The controller then controls the lifting cylinder 25 to lift, and the lifting cylinder 25 immediately moves the labeling mechanism upwards, completing the labeling task.

[0045] When cylindrical or irregularly shaped items need to be labeled, the workflow is as follows: Telescopic cylinder 27 extends the vacuum suction cup 4 close to the label peeling mechanism of label printer 100. After label printer 100 prints and peels off the label, vacuum suction cup 4 picks up the label. Simultaneously, air pipe 18 blows high-pressure gas to better adhere the label to vacuum suction cup 4. Then, telescopic cylinder 27 retracts the vacuum suction cup 4, and air pipe 18 stops blowing gas. Lifting cylinder 25 moves the labeling mechanism downwards along linear guide rail 23. When magnetic switch sensor 30 detects that vacuum suction cup 4 has contacted the item, magnetic switch sensor 30 sends a contact signal to the controller, which then controls the lifting mechanism to... The lowering cylinder 25 is raised, and the lifting cylinder 25 immediately moves the labeling mechanism upward. Then, the controller controls the flipping cylinder 26 to switch the positions of the vacuum suction cup 4 and the sponge pressure plate 1, so that the sponge pressure plate 1 faces the item. The lifting cylinder 25 moves the labeling mechanism downward, and the sponge pressure plate 1 can press the label onto the irregularly shaped item. When the magnetic switch sensor 30 detects that the sponge pressure plate 1 is in contact with the item, the magnetic switch sensor 30 sends a contact signal to the controller. The controller controls the lifting cylinder 25 to be raised, and then the flipping cylinder 26 switches the positions of the sponge pressure plate 1 and the vacuum suction cup 4, so that the vacuum suction cup 4 returns to its original position facing the item. The labeling task is completed.

[0046] In summary, the labeling device of the present invention is adaptable to items of various shapes, and can label items of different shapes, and is simple to operate.
