Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a closed-type printing press drying device, which utilizes a graphene heating plate and a fan for heating and drying. Background Technology

[0002] In existing printing techniques, the ink in the printed image contains a small amount of water. The evaporation of water can be accelerated by the action of hot airflow, allowing the image to be displayed on the substrate fabric.

[0003] Most photo printers on the market currently use an open-type infrared lamp heating drying method, as indicated in the instruction manual. Figure 7 As shown in the accompanying diagram, an infrared lamp 7 is installed inside the housing 6. A linearly arranged fan 8 ensures that the heat generated by the infrared lamp 7 is distributed more evenly to the substrate fabric. This allows the heat and airflow to achieve a dual evaporation effect on the ink on the substrate fabric, accelerating the evaporation of moisture in the ink and promoting image drying. Because the printing substrate fabric is heated from one side only, and the infrared lamps are very hot, the lamps must be at least 10cm away from the substrate fabric to prevent deformation from baking. This causes most of the heat to escape into the air, resulting in energy loss, high electricity consumption, and a high operating environment temperature.

[0004] Therefore, the existing technology has the following drawbacks: First, it has low energy efficiency and high energy consumption. The dryer is located on one side of the substrate fabric and uses an open drying method, causing most of the heat to dissipate to the outside, resulting in low energy efficiency and high energy consumption. Second, the working environment for operators is harsh. Since most of the heat is dissipated into the air, the ambient temperature at the operating site is very high, especially in individually owned printing shops where the space is already small, causing the room temperature to rise very quickly. The high working temperature directly restricts the development of individual advertising businesses. Third, the printed image may be distorted. Using this open baking method for different styles of printed images may result in localized over-baking and under-baking. Uneven heating can also cause deformation of the substrate fabric. Furthermore, the subsequent fan blowing air onto the substrate fabric causes the fabric to cool rapidly due to moisture evaporation, leading to a decrease in the quality of the machine-generated image. Utility Model Content

[0005] This utility model provides a closed graphene heating dryer. The purpose of this application is as follows: First, it improves the image quality of the printing equipment output; second, it improves the energy utilization rate of ink drying on the substrate fabric of the dryer; third, it provides the operator with a more suitable working environment temperature; and fourth, it improves the overall service life of the dryer.

[0006] The solution is as follows: A closed graphene heating dryer includes a shell 1 and a fan 2. The shell 1 forms a cavity 1-3. The fan 2 is installed in the cavity 1-3 of the shell 1. A fabric inlet and a fabric outlet are respectively provided at the top and bottom of the shell 1. A first graphene heating plate 3 is installed in the cavity 1-3. The plane of the first graphene heating plate 3 is parallel to the substrate fabric surface 12.

[0007] Preferably, the outer casing 1 includes a movable outer casing 1-1 and a fixed outer casing 1-2.

[0008] Preferably, the lower ends of the movable outer shell 1-1 and the fixed outer shell 1-2 are connected by a hinge, and the upper ends of the movable outer shell 1-1 and the fixed outer shell 1-2 are connected by a snap fastener.

[0009] Preferably, a fabric guide 4 is installed at the upper end of the fixed housing 1-2 near the fabric inlet and at the lower end near the fabric outlet.

[0010] Preferably, the guide fabric component 4 is a profile with an arc-shaped structure.

[0011] Preferably, the first graphene heating plate 3 is installed inside the movable outer shell 1-1, and the second graphene heating plate 5 is installed inside the fixed outer shell 1-2.

[0012] Preferably, the first graphene heating plate 3 and the second graphene heating plate 5 include a graphene heating film 10 and a substrate 11, wherein the graphene heating film 10 is attached to the substrate 11.

[0013] Preferably, 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, and the copper strip 109 covers the silver strip 108.

[0014] 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 image from the inside out, resulting in a smooth image, strong adhesion, and long-lasting colors. The heat within the cavities 1-3 is repeatedly recycled through airflow circulation by fan 2, and the first graphene heating plate 3 and the second graphene heating plate 5 heat both sides of the image within the cavities 1-3, 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, resulting in most of the heat being retained within the cavities 1-3 of the outer shell 1. The heat within the cavities 1-3 is repeatedly recycled through airflow circulation by fan 2. Furthermore, the inherent energy-saving characteristics of graphene heating have a beneficial impact on the application scenario; over 90% of the heat generated by graphene heating 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 comfort of the operator's working environment is improved. Since most of the heat is enclosed within the outer casing, it is not dissipated into the surrounding environment in large quantities, resulting in a suitable ambient temperature at the operating site, especially for smaller individual printing shops. Fourth, the graphene heating plate has a long service life and requires no maintenance. Graphene material has good stability and slow degradation, with a service life of over 10,000 hours, essentially requiring no maintenance. Attached Figure Description

In the working state, the plane of the first graphene heating plate 3 is parallel to the substrate fabric surface 12. The outer shell surrounds the cavity, which is a closed feature. The plane of the heating plate is parallel to the fabric surface. This embodiment adopts a surface heating method, and the substrate fabric surface 12 is heated evenly.

The upper plastic layer 101 encapsulates the graphene paste layer 103, the silver strip 108, and the copper strip 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 plastic.
