The application fields of laser materials are very wide, and they have been rapidly promoted in industries such as food, medicine, daily chemicals, tobacco and alcohol, clothing, gift packaging, and decorative materials.

[0003] Curing, also known as curing, is the process of placing the composite film into a curing chamber. It is the process in which the main agent and curing agent of the polyurethane adhesive react and cross-link and interact with the surface of the composite substrate. The main purpose of curing is to allow the main agent and curing agent to fully react within a certain period of time in order to achieve the required composite strength. Curing control is mainly the control of curing temperature and curing time.

[0004] During the maturation operation, it is often necessary to heat the air through equipment such as drying lamps to control the temperature inside the maturation chamber at a high and stable level. Currently, this is often achieved by heating the air and then transporting it to the inside of the maturation chamber. However, current equipment often directly heats the outside air and then discharges it to achieve air circulation to maintain the temperature inside the cavity, which requires high energy consumption and high cost.

[0005] Therefore, how to maintain the cavity temperature inside the curing chamber while saving energy is a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Reference Figure 1-3 , an embodiment of the utility model is proposed, a aging device for laser film production, comprising an equipment box 1, both sides of the equipment box 1 are transversely penetrated with inlet and outlet ports 2, the front and rear ends of the lower surface of the equipment box 1 are fixedly connected with support plates 3, and a conveyor belt 4 is transversely arranged between the top ends of the two support plates 3, and the two ends of the conveyor belt 4 extend outward through the two inlet and outlet ports 2 respectively;

[0023] A first hot air box 5 with a hollow interior and adapted to the length of the conveyor belt 4 is laterally fixedly connected between the two support plates 3 and below the conveyor belt 4. A plurality of first air outlets 6 are vertically penetrated through the upper surface of the first hot air box 5. The bottom end of the first hot air box 5 is connected to a plurality of first air ducts 7. The other ends of the plurality of first air ducts 7 penetrate through the rear surface of the equipment box 1, bend upward and extend to the top end of the rear surface of the equipment box 1. The top end of the rear surface of the equipment box 1 is connected to a plurality of first exhaust pipes 8, and the plurality of first air ducts 7 are respectively connected to the plurality of first exhaust pipes 8.

[0024] A second hot air box 9 which is hollow inside and matches the length of the conveyor belt 4 is fixedly connected transversely inside the equipment box 1 and located above the conveyor belt 4. A plurality of second air outlets 10 are vertically penetrated through the bottom end of the second hot air box 9. A plurality of second air ducts 11 are connected to the top end of the second hot air box 9. The other ends of the plurality of second air ducts 11 penetrate the rear surface of the equipment box 1, bend downward and extend to the bottom end of the rear surface of the equipment box 1. A plurality of second exhaust pipes 12 are connected to the bottom end of the rear surface of the equipment box 1. The plurality of second air ducts 11 are respectively connected to the plurality of second exhaust pipes 12.

[0025] Exhaust fans are disposed inside the plurality of first exhaust pipes 8 and the plurality of second exhaust pipes 12 .

[0026] The outer surfaces of the plurality of first air ducts 7 and the plurality of second air ducts 11 at the rear side of the equipment box 1 are fixedly connected with device tubes 13 , the interiors of the plurality of device tubes 13 are provided with heating wires 14 , and the outer surfaces of the plurality of device tubes 13 are covered with heat insulation sleeves 15 .

[0027] When the device is running, multiple exhaust fans will start, and then air can be drawn from the outside into the interior of the device. The air entering from the outside enters the interiors of multiple first exhaust pipes 8 and multiple second exhaust pipes 12 respectively through multiple exhaust fans, and then enters the interiors of multiple first air ducts 7 and multiple second air ducts 11 respectively, and finally enters the interiors of the first hot air box 5 and the second hot air box 9 and is discharged through multiple first air outlets 6 and multiple second air outlets 10. In this process, the air is heated by the heating wires located on the outer surfaces of the multiple first air ducts 7 and the multiple second air ducts 11. When the air returns to the interior of the equipment box 1 again, its temperature is increased and can mature the laser film.

[0028] The hot air discharged from the multiple first air outlets 6 rises and is then drawn into the interior of the second air duct 11 through the multiple second exhaust pipes 12. At the same time, the hot air discharged from the multiple second air outlets 10 descends and is then drawn into the interior of the first air duct 7 through the multiple first exhaust pipes 8. In this way, the high-temperature air inside the equipment can be circulated back and forth. In this process, since the air itself has a certain amount of heat, the heat required to heat it again will become smaller, thereby reducing production costs.

[0029] The heat insulating sleeves 15 on the outer surfaces of the multiple device tubes 13 all have a heat insulating effect, which can have a heat preservation effect and improve the heating capacity of the multiple heating wires 14.

[0030] Furthermore, a plurality of drying lamps 16 are transversely fixedly connected inside the equipment box 1 and between the second hot air box 9 and the conveyor belt 4 .

[0031] The plurality of drying lamps 16 further increase the temperature inside the device, thereby improving the curing efficiency.

[0032] The device is also provided with a thermometer inside, through which the temperature inside the equipment box 1 is detected in real time, so that the staff can adjust the temperature of the heating structure.

[0033] Furthermore, a plurality of air inlet holes 17 are transversely penetrated through the rear surface of the equipment box 1, an electrically controlled telescopic rod 18 is vertically fixedly connected to the rear surface of the equipment box 1 and below the air inlet holes 17, a closing plate 19 adapted to the plurality of air inlet holes 17 is fixedly connected to the output shaft surface of the electrically controlled telescopic rod 18, and the closing plate 19 fits tightly to the rear surface of the equipment box 1.

[0034] At the beginning, outside air is drawn into the interior of the device through multiple air inlet holes 17. Filters are fixedly connected to the interior of the multiple air inlet holes 17 to filter dust in the air to prevent it from affecting the final quality of the laser film. After the hot air inside the equipment is circulated, the air inlet holes 17 can be closed by controlling the movement of the closing plate 19 through the electrically-controlled telescopic rod 18 to maintain the stability of the hot air circulation inside the device.

[0035] Furthermore, the top ends of the two inlet and outlet ports 2 are fixedly connected with door curtain strips 20 .

[0036] The door curtain strip 20 can cover most of the inlet and outlet 2 to prevent excessive outside air from entering the interior of the device through the inlet and outlet 2 and affecting the operation of the device.

[0037] Furthermore, a plurality of air holes 21 are formed through the surface of the conveyor belt 4 .

[0038] The multiple air holes 21 enable the hot air to move smoothly inside the device, thereby ensuring the smoothness of the entire hot air circulation.

[0039] A plurality of support pads 22 are fixedly connected to the bottom end of the equipment box 1. The plurality of support pads 22 can lift the equipment box 1 as a whole off the ground to prevent the bottom end from directly contacting the ground and being worn.

[0040] During operation, when the device is in operation, the exhaust fans in the multiple exhaust pipes operate to draw outside air into the interior of the device, and then enter the first hot air box 5 and the second hot air box 9 after being heated through the first air duct 7 and the second air duct 11, and then be discharged through the first hot air box 5 and the second hot air box 9. The high-temperature air discharged by the two is sucked into the first exhaust pipe 8 and the second exhaust pipe 12 respectively, and then enters the first air duct 7 and the second air duct 11 again to form a reciprocating cycle. During the circulation process, since the gas inside the equipment itself has been heated, when the air needs to be heated again, a particularly high temperature is not required, thereby reducing the energy consumption of the device and reducing the operating cost.

[0041] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
