Description

Technical Field

[0001] The utility model relates to the technical field of printing, and more particularly to a water-based inkjet ink drying box. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In the printing industry, water-based inkjet printing technology is widely used due to its environmentally friendly, efficient, and vibrant colors. However, after being printed on paper, water-based inkjet ink requires time to dry to ensure the quality of the printed product and smooth subsequent processing. Traditional drying methods often suffer from low drying efficiency, high energy consumption, and uneven drying, which affects the production efficiency and quality of printed products.

[0004] To address these issues, a variety of drying equipment has emerged on the market, but they still have numerous shortcomings in performance and effectiveness. For example, some drying equipment utilizes large air vents, which, while increasing air flow, often results in insufficient air velocity and poor drying results. Other equipment utilizes high-temperature drying methods, which, while accelerating the ink drying process, can easily cause thermal damage to the paper, affecting the quality of the printed product.

[0005] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention. Summary of the Invention

[0007] In order to solve the above technical problems, the utility model provides an aqueous inkjet ink drying box, wherein the drying box includes a box body and a cover plate covering the front side of the box body, wherein a paper feeding channel for paper to pass through in an upward and downward direction is formed between the box body and the cover plate, and the drying box also includes an upper air duct assembly and a lower air duct assembly, wherein the upper air duct assembly includes a transversely arranged upper air duct, one end of the upper air duct is provided with an upper air inlet, the upper air inlet is located outside the box body, and a plurality of air outlet holes are opened on the side wall of the upper air duct, the lower air duct assembly includes a transversely arranged lower air duct, one end of the lower air duct is provided with a lower air outlet, the lower air outlet is located outside the box body, and an air inlet gap is opened on the side wall of the lower air duct, so that air used for drying enters the upper air duct from the upper air inlet and enters the interior of the box from the air outlet, the air inside the box enters the lower air duct from the air inlet gap, and the air in the lower air duct is discharged through the lower air outlet.

[0008] Preferably, an upper paper outlet is formed between the upper end of the box body and the cover plate, and a lower paper outlet is formed between the lower end of the box body and the cover plate. The paper feed channel is formed between the upper paper outlet and the lower paper outlet. The gas blown out from the air outlet passes through the paper feed channel and then enters the air inlet gap. The air inlet gap is a gap opened horizontally on the lower air duct.

[0009] Preferably, the upper air duct includes a first air outlet portion arranged vertically and a second air outlet portion arranged obliquely downward, and the first air outlet portion and the second air outlet portion are both provided with a plurality of the air outlet holes.

[0010] Preferably, the box body is provided with an infrared drying component for drying, an infrared reflection plate of the infrared drying component, and a plurality of infrared lamps arranged in front of the infrared reflection plate.

[0011] Preferably, the upper end of the infrared reflective plate is connected to the upper air duct, and the lower end of the infrared reflective plate is connected to the lower air duct.

[0012] Preferably, the upper air duct is installed with a horizontally arranged upper connecting bar, and the upper connecting bar has multiple upper connecting parts arranged in the horizontal direction. The down air duct is installed with multiple horizontally arranged lower connecting bars, and the lower connecting bar has multiple lower connecting parts arranged in the horizontal direction. The upper part of the infrared reflector is provided with multiple upper mounting holes arranged in the horizontal direction, and the lower part of the infrared reflector is provided with multiple lower mounting holes arranged in the horizontal direction.

[0013] Preferably, the upper and lower ends of the infrared lamp tube are connected to the upper connecting piece and the lower connecting piece respectively.

[0014] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0015] The water-based inkjet ink drying box of this utility model uses drying air to enter through the upper air inlet and then be blown out through the air outlet. Due to the small size of the air outlet, the dry air can be blown out at a higher wind speed, ensuring that the air forms a high-speed airflow when blown out, thereby achieving a faster and more uniform drying effect as the paper passes through the paper feed channel. In addition, due to the above-mentioned structural features, the drying effect is significantly improved, so the size of the drying box can be designed to be more compact, without increasing the size of the equipment to achieve sufficient drying effect. This design not only saves space and reduces material costs, but also improves the portability and installation flexibility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
