Description

Technical Field

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

[0002] Existing technologies for large-format printing include laser printing and inkjet printing. Laser printing is faster and more efficient, but its color fidelity is insufficient, making it suitable for mass production. Inkjet printing, while slower, offers higher image quality. Inkjet printing produces images with ink containing a small amount of water; the use of hot airflow accelerates the evaporation of this water, allowing the image to appear on the canvas.

[0003] Instruction manual attached Figure 8 As shown in the accompanying drawing for the background technology of this application, an infrared lamp tube 19 is installed inside the housing 18. The linearly arranged fans 20 cause the heat generated by the infrared lamp tube 19 to be delivered more evenly to the canvas surface, so that the heat and airflow can play a dual evaporation role on the ink on the canvas to accelerate the evaporation of water in the ink and promote the drying and imaging of the canvas.

[0004] While this solution meets the basic requirements for air-drying and imaging, the following technical defects have been found in the long-term use of this printer's dryer: First, low energy efficiency and high energy consumption. The dryer is located on one side of the canvas 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, harsh working environment for operators. Because 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. This high working environment directly restricts the development of individual advertising businesses. Third, potential distortion of the printed image. The open baking method, which applies to different styles of printed images, may result in localized over-baking and under-baking. Furthermore, the subsequent fan blowing on the canvas causes the canvas to cool rapidly due to moisture evaporation, leading to a decrease in the realism of the printed image. Utility Model Content

[0005] This utility model provides a hot air crossflow circulating graphene heating dryer. The purpose of this application is as follows: First, it improves the energy utilization rate of the dryer for drying canvas ink; second, it provides the operator with a more suitable working environment temperature; and third, it improves the image quality of the printing equipment output.

[0006] The solution is as follows: A hot air crossflow circulating graphene heating dryer includes a mounting bracket 1, a dryer body 2, a first roller 3, and a second roller 4. The mounting bracket 1, the first roller 3, and the second roller 4 are all connected to the dryer body 2. The dryer body 2 includes a shell 5 and a cavity 8 enclosed by the shell 5. A graphene heating plate 9 is installed inside the cavity 8, and the plane of the graphene heating plate 9 is parallel to the fabric surface 12. The graphene heating plate 9 includes a graphene heating film 10 and a substrate 11. The graphene heating film 10 is adhered to the substrate. The graphene heating film 10 is located on the substrate 11. It 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. A crossflow fan 6 is installed on the outer shell 5.

[0007] Preferably, the crossflow fan 6 includes a housing 15, a motor 7, a rotor 14, and a mounting frame 16. The mounting frame 16 is fixedly connected to the housing 5. The output end of the motor 7 is connected to the rotor 14, and the rotor 14 is located inside the housing 15. The housing 15 is provided with an air inlet 13 and an air outlet 17.

[0008] Preferably, the air inlet 13 and air outlet 17 of the crossflow fan 6 are both located within the cavity 8.

[0009] The beneficial effects of this utility model are as follows: First, energy utilization efficiency is improved and energy consumption is reduced. This application adopts a closed drying method, which results in most of the heat being retained in the cavity 8 of the outer shell 5. Furthermore, the heat within the cavity 8 is repeatedly recycled using airflow through a fan, thus achieving high energy utilization efficiency and low energy consumption. Second, the comfort of the working environment for operators is improved. Since most of the heat is sealed and retained within the outer shell 5, a large amount of heat is not dissipated into the surrounding environment, resulting in a suitable ambient temperature at the operating site, especially for individual printing shops with smaller spaces. Third, the realism of the printed image is improved. The repeated recycling of heat within the cavity 8 using airflow through a fan, coupled with the use of a graphene heating plate 9 to heat the entire surface of the print within the cavity 8, improves the uniformity of heating and enhances the output image quality. Additionally, the energy-saving characteristics of the graphene heating plate 9 further improve energy efficiency, and the use of graphene heating material significantly extends the product's lifespan. Fourth, this product uses a cross-flow fan for heat dissipation, which further improves the drying quality and greatly enhances the quality of the output drawings. Attached Figure Description

[0027] It should be noted that the ink has a low water content, and the water vapor generated by evaporation inside cavity 8 can seep out directly from the gap between cavity 8 and the outside, and will not have an adverse effect on the painting due to excessive moisture inside cavity 8.
