A preheating mechanism is provided inside the fixed frame 1, consisting of a first hood 8, a finned heater 9, and a first diversion mesh plate 10. The first hood 8 is fixedly connected to the inner wall of the fixed frame 1, and the air inlet of the first hood 8 is fixedly connected to the air outlet of the air duct 5. The finned heater 9 is fixedly connected to the inner wall of the first hood 8, and the first diversion mesh plate 10 is fixedly connected to the inner wall of the first hood 8. This device is used to preheat the sheet material, facilitating the extrusion and lamination of the sheet. In the melting process, a cooling assembly is installed inside the air duct 5. The cooling assembly consists of a semiconductor cooling chip 11, a heat dissipation fan 12, a second air shroud 13, and a second diverter plate 14. There are multiple semiconductor cooling chips 11, all located inside the air duct 5, which are used to absorb heat and reduce the air temperature, thereby improving cooling efficiency. The semiconductor cooling chip 11 is fixedly connected to the inner wall of the air duct 5. The heat dissipation fan 12 is fixedly connected to the surface of the air duct 5. The second air shroud 13 is fixedly connected to the inner wall of the fixed frame 1, and the air inlet end of the second air shroud 13 is fixedly connected to the air outlet end of the air duct 5. The second diverter plate 14 is fixedly connected to the inner wall of the second air shroud 13, which is used to reduce the air temperature and blow it onto the high-temperature sheet, facilitating rapid cooling and shaping of the sheet. A pressing hot melting mechanism is installed inside the fixed frame 1, and a conveying assembly is installed on the front of the fixed frame 1.

[0021] Specifically, the downward pressing hot melt mechanism consists of an electric push rod 15, a fixed frame 16, a pressure roller 17, and a heating rod 18. The fixed frame 16 is rectangular and made of metal. The metal fixed frame 16 has higher strength, is less prone to deformation and damage under stress, and is more durable. The electric push rod 15 is fixedly connected to the inner wall of the fixed frame 1, the fixed frame 16 is fixedly connected to the output end of the electric push rod 15, the pressure roller 17 is rotatably connected to the inner wall of the fixed frame 16, and the heating rod 18 is fixedly connected to the inner wall of the pressure roller 17. It is used to heat and extrude the sheet material, which facilitates the composite hot melt operation of multiple sheets.

[0022] Specifically, the conveying assembly consists of a servo motor 19, a transmission roller 20, and a conveyor belt 21. The servo motor 19 is fixedly connected to the front of the fixed frame 1, and the output end of the servo motor 19 is rotatably connected to the inner wall of the fixed frame 1. The transmission roller 20 is fixedly connected to the output end of the servo motor 19, and the transmission roller 20 is rotatably connected to the inner wall of the fixed frame 1. The inner wall of the conveyor belt 21 meshes with the surface of the transmission roller 20, which is used to move the sheet to the right, thereby improving production continuity.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: First, stack the multiple sheets to be hot-melt laminated and place them on the top surface of conveyor belt 21. Start servo motor 19 to drive transmission roller 20 to rotate along the inner wall of fixed frame 1. Through the meshing of transmission roller 20 and conveyor belt 21, the sheets are moved to the right. Start fan 7 to draw air into air duct 5 through suction pipe 6. After the air is diverted through air duct 5, it is sent into first air hood 8. Start finned heater 9 to heat the air inside first air hood 8. After the hot air is diverted through first diversion mesh plate 10, it is blown onto the sheets below, thus preheating the sheets. Start heating rod 18 to heat the pressing... Roller 17, the electric push rod 15 is activated to push the pressure roller 17 downward to contact the sheet through the fixed frame 16. With the support plate 2, multiple sheets can be extruded and composited for hot melting. At the same time, the semiconductor cooling chip 11 is activated to absorb and release heat. The heat absorption end of the semiconductor cooling chip 11 absorbs heat from the inside of the air duct 5 to reduce the air temperature. The heat dissipation fan 12 is activated to dissipate heat from the heat release end of the semiconductor cooling chip 11. The low temperature air enters the second air hood 13 and is then blown downwards through the second diversion mesh plate 14 to the sheet below, so that the composited hot-melted sheet can be quickly cooled and shaped.

[0025] In summary, this plastic PVC sheet hot-melt device stacks multiple sheets and places them on top of the conveying assembly. The conveying assembly is then activated to move the sheets to the right. The blower 7 draws air through the suction pipe 6 into the air duct 5, preheating mechanism, and cooling assembly. The preheating mechanism heats the air and blows it onto the sheets for preheating. The pressing hot-melt mechanism, in conjunction with the support plate 2, compresses and heat-melts the sheets. The cooling assembly lowers the air temperature and blows it onto the sheets, thus rapidly cooling and shaping the heat-melted sheets. This achieves the goal of facilitating rapid cooling and shaping of the heat-melted sheets, avoiding the problem of deformation and damage caused by impacts from hard objects at high temperatures, which is common in existing hot-melt devices lacking a cooling mechanism. This significantly improves production stability and solves the problems mentioned in the background art.
