[0002] Hot stamping transfer film is a thin film used to hot stamp patterns or text onto the surface of various materials. It is typically composed of a substrate, a color layer, an adhesive layer, and a protective layer. After production, hot stamping transfer film needs to be cut into different widths to meet various application requirements. Patent publication number CN216831211U discloses a cutting device for hot stamping film production, including a worktable. Two electric telescopic rods are bolted to the top outer wall of the worktable near both side edges. The tops of the two electric telescopic rods on the same side are bolted to the same horizontal plate. Two support plates are fixedly connected to the top outer wall of the horizontal plate. The tops of the four support plates are fixedly connected to the same top plate. A first vertical plate and a second vertical plate are fixedly connected to the bottom outer wall of the top plate near both side edges. Circular rollers and crossbars are fixedly connected to the outer walls of the two first vertical plates and the two second vertical plates on opposite sides. This utility model relates to a cutting device for transfer film production. The device can cut the transfer film and allows the operator to easily adjust the cutting width of the transfer film as needed during use, thus improving the device's practicality. However, this cutting device cannot adjust the tension of the transfer film when cutting it. When the tension of the transfer film changes, it is easy to cause irregular cutting of the transfer film, which is not conducive to the processing of the transfer film. Therefore, we propose a hot stamping transfer film cutting device. Utility Model Content
