[0021] Please see Figures 1-4In this embodiment, a hot-press wrapping device for printing and packaging is provided, including a processing table 10. A lower mold 1 is provided on the upper surface of the processing table 10, and guide frames 2 are fixedly mounted on both sides of the processing table 10. A top plate 3 is fixedly mounted on the upper end of the two guide frames 2. A first hydraulic cylinder 4 is mounted on the top plate 3. An upper mold 5 is connected to the piston rod of the first hydraulic cylinder 4. A packaging film 6 is provided on the lower surface of the upper mold 5 and the upper surface of the lower mold 1, and the packaging film 6 is wrapped around the guide frames 2. A product packaging cavity 7 is opened on both the upper mold 5 and the lower mold 1, and an electric heating coil 8 is provided on the lower surface of the upper mold 5. The electric heating coil is a low-temperature electric heating element, which can be made of a PTC constant temperature heating element. It can be manufactured into various shapes and specifications using ceramic technology. The most common shapes are strip, sheet, and ring. The heating coil 8 can use a rectangular ring-shaped PTC heating element, which is a mature existing technology and will not be described in detail. It should be noted that a heat-conducting metal layer is fixedly connected to the lower surface of the heating coil 8 to prevent damage caused by the cutting blade 9 during cutting. A metal washer 80 is set on the upper surface of the lower mold 1 below the heating coil 8. A cutting groove 81 is opened in the metal washer 80, and the cutting blade 9 is set in the cutting groove 81. A through groove 13 is opened on the inner surface of the lower mold 1, which is connected to the cutting groove 81. The cutting blade 9 passes through the cutting groove 81 and the through groove 13 and extends into the interior of the processing table 10. The cross-section is rectangular. A second hydraulic cylinder 12 is fixedly installed at the bottom of the processing table 10. A connecting plate 11 is fixedly connected to the piston rod at the top of the second hydraulic cylinder 12, and the connecting plate 11 is fixedly connected to the cutting blade 9. By setting an electric heating ring 8 inside the upper mold 5, the packaging film 6 at the metal gasket 80 of the lower mold 1 can be thermally pressed. After pressing, the cutting blade 9 can be driven to penetrate into the cutting groove 81 to cut the edge of the pressed packaging film, thus completing the packaging and cutting work of the packaged product in one step, eliminating the hassle of multiple processing steps and improving processing efficiency. Specifically, the books or corresponding products to be packaged are placed between the upper mold 5 and the lower mold 1. The product cavity 7 is located between two packaging films 6. Then, the first hydraulic cylinder 4 is activated to drive the upper mold 5 to press down, pressing the product into the packaging product cavity 7. During the pressing process, the guide frame 2 can effectively tension the packaging film 6 to prevent wrinkles. After pressing, the heating coil 8 can effectively heat-press the edges of the two packaging films 6 to complete the sealing. After sealing, the second hydraulic cylinder 12 is activated to drive the connecting plate 11 and the cutter 9, so that the cutter 9 penetrates into the cutting groove 81 to cut the edges of the pressed packaging film. This completes the packaging and cutting of the product in one step, eliminating the need for multiple processing steps and improving processing efficiency.

[0022] In this embodiment, the guide frame 2 includes a tension roller 21 and a guide roller 22 rotatably mounted on the frame body. The guide frame 2 has a slide groove 23, and a slider 25 is movably mounted on the slide groove 23 via a spring 24. A connecting shaft is rotatably mounted on the slider 25, and the tension roller 21 is rotatably mounted on the connecting shaft. By utilizing the cooperation of the slide groove 23, the spring 24, and the slider 25, the tension roller 21 on the guide frame 2 can keep the packaging film 6 in a taut state at all times, thereby effectively preventing wrinkles from appearing on the packaging film 6 during processing.
