[0002] The transfer mechanism is an important equipment developed in modern industrial manufacturing to meet the transfer needs of uneven workpiece surfaces. Traditional transfer technology often finds it difficult to ensure the quality and efficiency of transfer when facing arc-surface or curved workpieces, and is prone to problems such as bubbles during the transfer process. In order to solve this problem, a transfer mechanism suitable for arc-surface transfer has emerged. This transfer mechanism usually includes a workbench, a hot stamping plate upper plate and a lower plate. The upper surface of the hot stamping plate lower plate is provided with a groove for embedding materials such as PET plastic sheets; and the lower surface of the hot stamping plate upper plate is provided with a die with an arc surface to adapt to workpiece surfaces with different curvatures. This transfer mechanism can achieve high-quality transfer on arc-surface workpieces, effectively avoiding the generation of problems such as bubbles. The transfer mechanism suitable for arc-surface transfer is increasingly widely used in various fields, providing strong support for the development of modern manufacturing.

[0003] However, the existing transfer mechanism has problems such as poor transfer effect on curved surfaces and inability to transfer to the edges of curved surfaces. On the other hand, it has poor clamping effect on shells of different specifications. Therefore, we propose a transfer mechanism suitable for curved surface transfer. Utility Model Content

[0028] Please see the attached Figure 1 -Attached Figure 5 The utility model provides a transfer mechanism suitable for arc surface transfer, including a transfer machine body 11, a box door 12 is provided on the surface of the transfer machine body 11 through a hinge, an upper cavity 13 and a lower cavity 14 are provided inside the transfer machine body 11, the upper cavity 13 and the lower cavity 14 are connected to each other, five support rods 15 are fixedly installed inside the upper cavity 13, the outer surfaces of the five support rods 15 are respectively sleeved with a paper output drum 16, a paper receiving drum 17, a first roller 18, a second roller 20 and a heating cylinder 19, a clamping structure 23 is provided below the heating cylinder 19, and the clamping structure 23 includes an AC motor 24, one end of the AC motor 24 is fixedly installed on the inner wall of the upper cavity 13, and a clamping tube 25 is fixedly installed on the output shaft surface of the AC motor 24.

[0029] Please see the attached Figure 1 The other end of the support rod 15 on which the heating cylinder 19 is sleeved is fixedly installed with a locking shell 21. The heating cylinder 19 can be replaced with different models according to different shells. The purpose of setting the locking shell 21 is that the locking shell 21 can be removed when a different model of the heating cylinder 19 needs to be replaced. After the heating cylinder 19 is installed, the locking shell 21 is installed to prevent the heating cylinder 19 from separating from the support rod 15 during rotation.

[0030] Please continue to refer to the attached Figure 1 The paper discharge roller 16, the first roller 18, the heating cylinder 19, the second roller 20 and the paper receiving roller 17 are arranged in sequence and at intervals on the flow path of the printing paper 22. In this embodiment, the paper discharge roller 16 and the paper receiving roller 17 are arranged above the heating cylinder 19 and are respectively located on both sides of the heating cylinder 19. The first roller 18 and the second roller 20 are respectively arranged on both sides of the heating cylinder 19, and the first roller 18 is located below the paper discharge roller 16, and the paper receiving roller 17 is located below the second roller 20.

[0031] Please see the attached Figure 3The surface of the clamping tube 25 is provided with a transverse groove 26 along the extension direction of the support rod 15, and two T-shaped clamping plates 27 are provided inside the transverse groove 26. A double-headed screw rod 28 is movably installed at the center of the T-shaped clamping plate 27. The T-shaped clamping plate 27 and the double-headed screw rod 28 are threadedly engaged. The two T-shaped clamping plates 27 can move synchronously toward or away from each other along the transverse groove 26. One end of the double-headed screw rod 28 away from the inner wall of the upper cavity 13 where the AC motor 24 is installed passes through the clamping tube 25, and a torque handle 29 is fixedly installed at its end. The double-headed screw rod 28 Bearings are provided between the two ends of 8 and the clamping tube 25. By rotating the torque handle 29, the double-headed screw 28 is driven to rotate, and then the two T-shaped clamping plates 27 are driven to move synchronously along the transverse groove 26 to clamp or release the shell to be transferred. By setting up an AC motor 24 and a clamping tube 25, the transfer mechanism can flexibly adjust the angle to adapt to shell surfaces with different curvatures. This flexibility ensures precise alignment and stable contact during the transfer process, improves the transfer efficiency, and can process more types of curved shells, such as the back cover of a mobile phone.

[0032] Furthermore, a plurality of slit partitions 35 are fixedly installed inside the lower cavity 14, and the plurality of slit partitions 35 are arranged at intervals. Ventilation pipes 31 are fixedly installed at both ends of the lower cavity 14, and the ventilation pipes 31 are connected to the lower cavity 14. A fixed bracket 32 ​​is fixedly installed inside each ventilation pipe 31, and an AC motor 2 33 is fixedly installed on one side of the fixed bracket 32. The output shaft of the AC motor 2 33 is fixedly installed with fan blades 34. In this embodiment, one of the fan blades 34 in the ventilation pipes 31 on both sides blows air inward when rotating, and the other draws air outward when rotating. The AC motor 2 33 and the fan blades 34 can quickly take away the heat generated during the transfer process and reduce the temperature of the shell. In thermal transfer, the heating of the ink and film will generate a lot of heat. The high-temperature shell not only easily burns the operator, but may also accelerate the aging of the ink and the deformation of the shell. Four legs are fixedly installed at the bottom end of the transfer machine body 11, and a door handle is fixedly installed on the surface of the box door 12.

[0033] Working principle:

[0034] First, open the box door 12 through the box door handle, pull the printed paper 22 out of the paper output cylinder 16, bypass the first roller 18 and place it under the heating cylinder 19, then bypass the second roller 20 and connect it to the paper receiving cylinder 17, start the heating cylinder 19 to heat, rotate the torque handle 29 counterclockwise to drive the double-headed screw 28 to separate the two T-shaped clamps 27, place the shell to be transferred between the T-shaped clamps 27, twist the torque handle 29 clockwise to clamp the shell, start the AC motor 1 24, and the output shaft of the AC motor 1 24 drives the clamping tube 25 to rotate, so that the shell rotates synchronously with the clamping tube 25 and contacts the heating cylinder 19. After the transfer is completed, place the shell between the slit partitions 35, start the AC motor 2 33 to drive the fan blades 34 to rotate to generate wind, and take away the heat between the shells. At the same time, the circulation of air is also conducive to reducing the volatilization of harmful gases, further reducing the harm to the human body. At this point, the entire work process is completed.
