Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a dryer that uses a graphene heating plate for drying and heating, and this dryer has energy-saving characteristics. Background Technology

[0002] Currently, most photo printer drying systems on the market use infrared lamps for heating, which presents the following problems: 1. Uneven drying, posing quality risks. This can easily cause localized deformation and edge curling of the material, and the ink may dry on the surface but not on the underlying layer, affecting adhesion. 2. High energy consumption. Energy utilization efficiency is only about 30%, resulting in high electricity costs. 3. Safety hazards. The surface temperature of the lamp can reach several hundred degrees Celsius, easily causing burns or fires; strong infrared light may also damage the eyes. 4. Harsh working environment. Radiation significantly increases the ambient temperature around the equipment, especially increasing the air conditioning load in summer. 5. Short lamp lifespan. Lamp tubes are consumables with a lifespan of only about 4000 hours, requiring regular inspection and replacement.

[0003] To address the above technical deficiencies, there is a need to develop a safe, reliable, efficient, and energy-saving dryer. Utility Model Content

[0004] This utility model provides a graphene plate parallel heating dryer. The purpose of designing and developing this device is: first, to improve the image quality of the printing equipment output; second, to improve the energy utilization rate of ink drying on the substrate of the dryer; third, to provide the operator with a more suitable working environment temperature; and fourth, to improve the overall service life of the dryer.

[0005] The proposed solution is as follows: A graphene plate parallel heating dryer includes a shell 1 and a fan 2. The fan 2 is fixedly connected to the shell 1. A first graphene heating plate 3 is installed inside the shell 1. The plane of the first graphene heating plate 3 is parallel to the substrate fabric 8. The first graphene heating plate 3 includes a graphene heating film 10 and a substrate 11. The graphene heating film 10 is adhered to the substrate 11. The graphene heating film 10 includes an upper plastic layer 101, a lower plastic layer 102, a graphene paste layer 103, a silver strip 108, and a copper strip 109. The graphene paste layer 103, the silver strip 108, and the copper strip 109 are disposed between the upper plastic layer 101 and the lower plastic layer 102. The graphene paste layer 103 is printed on the lower plastic layer 102. The silver strip 108 is printed on the left and right ends of the graphene paste layer 103. The copper strip 109 covers the silver strip 108.

[0006] Preferably, a second graphene heating plate 7 is disposed inside the outer shell 1; the second graphene heating plate 7 is parallel to the first graphene heating plate 3, and the substrate fabric 8 moves between the first graphene heating plate 3 and the second graphene heating plate 7.

[0007] The beneficial effects of this utility model are as follows: First, the drying quality of the image is improved by using this dryer. The surface heating of the graphene plate ensures a uniform heat distribution across the entire width of the image, thereby achieving uniform curing of the ink from the inside out, resulting in a smooth image, strong adhesion, and long-lasting color. The fan 2 circulates airflow to repeatedly utilize the heat within the cavity, and the first graphene heating plate 3 and the second graphene heating plate 7 heat both sides of the image within the cavity, further improving the uniformity of heating and enhancing the output image quality. Second, energy efficiency is improved and energy consumption is reduced. This application uses a closed drying system, which retains most of the heat within the cavity of the shell. The fan 2 circulates airflow to repeatedly utilize the heat within the cavity. Furthermore, the energy-saving characteristics of the graphene heating method have a beneficial impact on the usage scenario. More than 90% of the heat generated by the graphene heating method acts on the substrate fabric surface, with less than 10% escaping into the air; this significantly saves electricity costs and reduces energy consumption. Third, the working environment for operators is improved. Because most of the heat is contained within the outer casing 1, it does not dissipate significantly into the surrounding environment, resulting in a suitable ambient temperature at the operating site. This is particularly beneficial for smaller individual printing shops where the working environment temperature is more comfortable. Fourth, graphene heating plates have a long service life and require no maintenance. Graphene material has good stability and slow degradation, with a service life exceeding 10,000 hours, essentially requiring no maintenance. Attached Figure Description

The graphene paste layer 103, silver strip 108, and copper strip 109 are disposed between the upper plastic layer 101 and the lower plastic layer 102. The graphene paste layer 103 is printed on the lower plastic layer 102, the silver strip 108 is printed on the left and right ends of the graphene paste layer 103, and the copper strip 109 covers the silver strip 108. This structure allows the graphene paste layer 103 to form an electric heating circuit, enabling it to heat up and operate. The silver bars 108 and copper bars 109, with their high conductivity, are used on the sides of the graphene paste layer 103 to form electrode areas, with two electrodes corresponding to the two sides of the graphene paste layer 103. The upper plastic layer 101 encapsulates the graphene paste layer 103, silver bars 108, and copper bars 109. The upper plastic layer 101 and the lower plastic layer 102 combine to form the entire graphene heating film 10 product. The upper plastic layer 101 and the lower plastic layer 102 can be made of PI (polyimide) material.

The second graphene heating plate 7 has the same structure as the first graphene heating plate 3.
