[0002] In the production of furniture cabinets, steel plates are used as cabinet panels, and the color of the steel plates themselves is relatively monotonous. In order to add specified colors and patterns to the surface of the cabinet panels, the existing processing methods are mainly thermal transfer methods: wrapping heat-resistant transfer paper with specified patterns on the surface of the cabinet panels. After heating, the patterns of the ink layer on the transfer paper will be transferred to the cabinet panels. They are not easy to fade, the patterns are realistic, and the product grade is high. They are widely used in high-temperature resistant metal materials such as aluminum alloy doors and windows, anti-theft doors, fire doors, steel and wood furniture, filing cabinets, computer cases, household appliances, metal accessories, etc.

[0003] However, in the existing cabinet board transfer work, the transfer paper is mainly wrapped on the cabinet board manually. Figure 1 The existing cabinet panel includes a main body and flanges around it, which are then manually transferred to a heating mechanism for transfer, which is time-consuming and labor-intensive, and has a relatively low work efficiency.

Through the above structure, when the outer edge wrapping swing frame drives the outer edge soft plate to approach the outer side surface of the flange of the cabinet board, the front of the outer edge soft plate first contacts the outer side surface of the flange of the cabinet board, and under the obstruction of the outer side surface of the flange of the cabinet board, the driving rack moves outward relative to the outer edge wrapping swing frame, thereby driving the driving gear to rotate, and the rotational power is transmitted to the inner edge wrapping swing frame through the inner edge wrapping synchronous belt and the two inner edge wrapping synchronous wheels, driving the inner edge wrapping swing frame to swing close to the upper end of the side wing of the transfer paper, and then the upper end of the side wing of the transfer paper is turned upside down and attached to the inner side surface of the flange of the cabinet board, at which time the reset spring deforms and stores energy to complete the edge wrapping work.

Then, the clamping assembly is driven by the stretching driving mechanism to move in the opposite direction, and at the same time, the unwinding driving mechanism drives the unwinding roller to rotate in the corresponding direction, so that the transfer paper is stretched out and covered on the wrapping workbench. At this time, the hemming mechanism is located below the transfer paper.
