[0002] On aluminum can production lines, it is often necessary to smoothly transport cans from one process to the next.

[0013] To make the structure and function of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0014] See appendix Figure 1-9 A device for the stable transport of aluminum cans includes a vacuum chamber 1, which is L-shaped with rounded corners. One side wall of the chamber near the can is configured with a perforated mesh structure 11, on which several adsorption holes 12 are formed. A conveyor belt 2 is wound around the outer surface of the vacuum chamber 1 and covers the perforated mesh structure 11. The conveyor belt 2 has several through holes 21, the diameter of which is smaller than the diameter of the bottom of the can and allows airflow to pass through. The through holes 21 communicate with at least a portion of the adsorption holes 12. A negative pressure source is connected to the vacuum chamber 1. The negative pressure source adsorbs the bottom of the can through the adsorption holes 12 and the through holes 21, causing the can to be suspended on the conveyor belt 2.

[0015] The rounded L-shaped cross-section design allows the conveyor belt 2 to smoothly transition when turning, avoiding stress concentration or interruption of adsorption force caused by right-angle turns, and ensuring that the tank can be stably adsorbed even in the arc section.

[0016] To ensure that the adsorption force can effectively act on the bottom of the can, the diameter of the through hole 21 is designed to be smaller than the minimum inner diameter of the can bottom, ensuring that the can bottom will not fall out of the through hole 21 or get stuck, while allowing airflow to pass smoothly. When the conveyor belt 2 is running in a cycle, the through hole 21 on it will periodically overlap and align with at least some of the adsorption holes 12 on the vacuum chamber 1, forming a through airflow channel.

[0017] When the equipment is running, the negative pressure source continuously draws in to maintain a stable negative pressure environment inside the vacuum chamber 1. This negative pressure is transmitted to the surface of the conveyor belt 2 through the adsorption hole 12 and the through hole 21, thereby firmly adsorbing the bottom of the can and making the can float on the conveyor belt 2 in a suspended conveying state detached from the lower tray.

[0018] It also includes a conveying mechanism, which comprises a chain 41, several rubber claws 42 fixed on the chain 41, and a drive assembly for driving the chain 41 to rotate. The drive assembly includes a motor 43, a belt 44, a flywheel 45, a drive shaft 46, a driving synchronous pulley 47, a synchronous belt 48, a driven synchronous pulley 49, a reducer 50, a transmission shaft 51, a first sprocket 52, a first chain 53, a second sprocket 54, a rigid shaft 55, and a third sprocket 56. The motor 43 drives the flywheel 45 to rotate via the belt 44. The flywheel 45 is mounted on the drive shaft 46, and the other end of the drive shaft 46 is connected to the driving synchronous pulley 47. The active synchronous pulley 47 drives the driven synchronous pulley 49 mounted on the reducer 50 via the synchronous belt 48. The output shaft of the reducer 50 is connected to the drive shaft 51. The first sprocket 52 is mounted on the drive shaft 51 and rotates synchronously with the drive shaft 51. The first sprocket 52 drives the second sprocket 54 via the first chain 53. The second sprocket 54 and the third sprocket 56 are mounted together on the rigid shaft 55. The rotation of the third sprocket 56 drives the chain 41 to move, thereby driving the rubber claw 42 to move. The rubber claw 42 includes three parallel arc-shaped plates with gaps, used to move the can to the vicinity of the conveyor belt 2.

[0019] The system also includes a conveyor support 5, which is positioned between the conveying mechanism and the conveyor belt 2. This support is used to convey the can from the gripper 42 to the conveyor belt 2. The conveyor support 5 comprises three parallel, spaced-apart long horizontal plates, which are interspersed with three curved plates. At the moment of transfer, the gripper 42 pushes the can forward to above the conveyor support 5. As the chain 41 drives the gripper 42 downward or backward, the three curved plates gradually withdraw from the gaps between the three long horizontal plates. At this point, the bottom of the can is smoothly supported by the three long horizontal plates, thus achieving a shock-free and damage-free transition of the can from the moving gripper 42 to the fixed conveyor support 5. Subsequently, the end of the conveyor support 5 smoothly connects with the beginning of the conveyor belt 2, and the can smoothly enters the negative pressure adsorption zone of the conveyor belt 2.

[0020] It also includes a guide channel 6, which is located on the side of the vacuum chamber 1 near the can. One end of the guide channel 6 is close to the conveying bracket 5, and the other end is provided with a can outlet 14. The interior forms the running channel for the can.

[0021] It also includes a connecting part 7 and a housing 8. The guide channel 6 is connected to the housing 8 through the connecting part 7. The housing 8 is disposed outside the device, and the negative pressure source is disposed through the housing 8.

[0022] It also includes a support roller and a drive motor 3 for driving the support roller to rotate. The support roller includes an active roller 91 and a driven roller 92. The active roller 91 is connected to the drive motor 3 for driving the conveyor belt 2 to rotate in a cycle. The active roller 91 and the driven roller 92 are respectively located outside the two ends of the vacuum cavity 1. The conveyor belt 2 is wound around the vacuum cavity 1 and the support roller.

[0023] After the drive motor 3 starts, it drives the active roller 91 to rotate. The active roller 91 drives the conveyor belt 2 to make continuous cyclic rotation between the surface of the vacuum chamber 1 and the support roller by friction. In order to ensure the stable placement of the can, the width of the conveyor belt 2 is configured to be greater than the maximum diameter of the can body, so that the bottom of the can completely rests in the belt area without exceeding the edge.

[0024] The vacuum chamber 1 has an air extraction port 13 on its top surface, and the air extraction port 13 is connected to the negative pressure source through a pipeline.

[0025] The width of the conveyor belt 2 is greater than the diameter of the can; the diameter of the adsorption hole 12 is greater than the diameter of the through hole 21.
