For example, after laminating a single document, if the laminating process is paused and the infrared heat radiation lamp is turned off, the temperature of the hot press roller will drop rapidly, requiring a long preheating time during subsequent heat sealing, which is time-consuming. If the heat radiation lamp is not turned off, the energy consumption is high, and it does not have the function of heating and heat preservation inside the roller.

[0004] Now, a new type of laminating machine that prevents heat loss is proposed to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are: the heat-preventing laminating machine not only realizes the function of heating and heat preservation inside the rollers, but also realizes the function of temperature monitoring and heat sealing pressure regulation;

[0016] (1) By setting up a hot press roller, a heat-conducting copper pipe, an electric heating wire, a roller shaft, a conductive slip ring, a conductive brush, a power module, a rock wool insulation layer and a ceramic lining, when in use, the geared motor drives the hot press roller to rotate at a constant speed. Under the irradiation of the infrared radiation heating lamp, the surface of the hot press roller heats up. With the help of the lower support roller below, the document below is heated while rolling, and heat sealing is completed. In the standby stage, the infrared radiation heating lamp stops working.

When it is used again, the temperature rises faster.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4 A laminating machine for preventing heat loss includes a bottom housing 1, a right housing 2 fixedly connected to the right side of the top of the bottom housing 1, a microcontroller 3 fixedly connected to the front end of the right housing 2, an outer cover 4 fixedly connected to the left side of the right housing 2, a left housing 5 fixedly connected to the left side of the top of the bottom housing 1, an infrared radiation heating lamp 6 horizontally fixedly connected between the middle positions of the opposite faces of the right housing 2 and the left housing 5, a hot press roller 8 horizontally movably connected between the bottom ends of the opposite faces of the right housing 2 and the left housing 5, a geared motor 7 installed at the bottom end inside the right housing 2, a lower support roller 19 provided below the hot press roller 8, a power module 14 fixedly connected to the right side inside the bottom housing 1, and a heat-insulating component provided inside the hot press roller 8 to prevent heat loss.

[0026] Please see Figure 1-4 A heat-preserving component is also included in a heat-preserving machine to prevent heat loss. The heat-preserving component includes a heat-conducting copper pipe 9, which is fixedly connected to the inside of the hot press roller 8. An electric heating wire 10 is installed inside the heat-conducting copper pipe 9. A roller shaft 11 is fixedly connected to the left side of the heat-conducting copper pipe 9. A conductive slip ring 12 is fixedly connected to the outside of the roller shaft 11. A conductive brush 13 is installed at the bottom of the inside of the left side shell 5. A ceramic liner 16 is provided inside the outer shell 4. A rock wool insulation layer 15 is filled between the outer shell 4 and the ceramic liner 16.

[0027] The output end of the geared motor 7 is connected to the right side of the hot press roller 8 via a coupling. The vertical center lines of the infrared radiation heating lamp 6 and the hot press roller 8 coincide. The conductive slip ring 12 and the conductive brush 13 are in contact with each other. The conductive brush 13 and the power module 14 are connected by conductivity. There is a distance between the outside of the heating wire 10 and the inner wall of the heat-conducting copper tube 9. The microcontroller 3, the heating wire 10, the conductive slip ring 12, the conductive brush 13, and the power module 14 are electrically connected. Heat loss is prevented by internal heating and insulation.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the standby phase, the infrared radiation heating lamp 6 stops working. According to the feedback from the sensor, when the temperature of the hot press roller 8 is lower than the preset threshold, the heating wire 10 in the heat-conducting copper pipe 9 conducts electricity and heats up. The heat is transferred to the surface of the hot press roller 8 through the heat-conducting copper pipe 9, so that it does not cool down, but the temperature is lower than the normal working temperature, which can reduce power consumption. When it resumes operation, the temperature rises faster. The conductive slip ring 12 and the conductive brush 13 work together to ensure power supply while ensuring rotation.

[0029] An infrared temperature sensor 17 is fixedly connected to the rear end of the outer casing 4. A sensor wiring 18 is movably connected between the microcontroller 3 and the infrared temperature sensor 17. The infrared temperature sensor 17 passes through the interior of the outer casing 4, the rock wool insulation layer 15, and the ceramic lining 16. The heights of the hot press roller 8 and the infrared temperature sensor 17 are matched. The microcontroller 3 and the infrared temperature sensor 17 are electrically connected to maintain temperature monitoring.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the infrared temperature sensor 17 monitors the surface temperature of the hot press roller 8 and feeds back the value to the display screen of the microcontroller 3 for easy reference.

[0031] Miniature electric cylinders 21 are installed on both sides of the front end of the bottom housing 1. Roller mounting frames 20 are provided on the left and right sides of the lower roller 19. A pre-grooved slot 22 is opened at the front end of the top of the bottom housing 1. The output end of the miniature electric cylinder 21 is fixedly connected to the roller mounting frame 20. The lower roller 19 and the roller mounting frame 20 are movably connected. The microcontroller 3 and the miniature electric cylinder 21 are electrically connected to facilitate the control of the heat sealing pressure.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the document to be heat-sealed passes between the hot press roller 8 and the lower support roller 19. The heat-sealing pressure, i.e. the distance between the hot press roller 8 and the lower support roller 19, can be adjusted according to the type and thickness of the document. The micro electric cylinder 21 extends or retracts, which can drive the roller mounting frame 20 and the lower support roller 19 to move up and down.

[0033] Working Principle: In operation, the reduction motor 7 drives the hot press roller 8 to rotate at a constant speed. Under the irradiation of the infrared radiation heating lamp 6, the surface of the hot press roller 8 heats up. Combined with the lower support roller 19 below, it heats the document below while rolling, completing the heat sealing process. During standby, the infrared radiation heating lamp 6 stops operating. Based on sensor feedback, when the temperature of the hot press roller 8 falls below a preset threshold, the heating wire 10 inside the heat-conducting copper tube 9 conducts electricity and heats up. This heat is transferred to the surface of the hot press roller 8 through the heat-conducting copper tube 9, preventing it from cooling down while keeping the temperature below the normal operating temperature, thus reducing power consumption. Subsequent operation results in faster heating. The conductive slip ring 12 and conductive brush 13 work together to ensure power supply while maintaining rotation. The infrared temperature sensor 17 continuously monitors the surface temperature of the hot press roller 8 and feeds the value back to the display screen of the microcontroller 3 for easy reference. The document to be heat-sealed passes between the hot press roller 8 and the lower support roller 19. The heat-sealing pressure, i.e. the distance between the hot press roller 8 and the lower support roller 19, can be adjusted according to the type and thickness of the document. The micro electric cylinder 21 extends or retracts, which can drive the roller mounting frame 20 and the lower support roller 19 to move up and down.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
