Description

Technical Field

[0001] This utility model relates to the field of sublimation transfer paper technology, specifically to a staged temperature and humidity controlled drying oven for sublimation transfer paper. Background Technology

[0002] Sublimation transfer is a new process that uses an inkjet printer containing sublimation transfer ink to print images such as portraits, landscapes, and text onto sublimation transfer inkjet paper in a mirror manner. The paper is then heated to about 200°C by a heat transfer device, causing the heat transfer ink on the paper to sublimate and penetrate into the substrate, thus realistically transferring the color image from the paper onto materials such as textiles, ceramic cups, ceramic plates, ceramic slabs, and metals.

[0003] In the prior art, application number 202422513596.7 discloses an oven for sublimation transfer paper, including a box body, an inlet, and an outlet. The inlet is located at the left end of the box body, and the outlet is located at the right end of the box body. A limiting drying component is provided on the box body. The above device completes the drying operation of the sublimation transfer paper in the box body in one go. Constant temperature drying results in a large amount of heat energy being wasted in the inefficient evaporation stage, causing significant damage and low efficiency. It cannot match the optimal drying parameters for different moisture contents and cannot dynamically control the temperature and humidity. Setting up a large number of drying devices to complete the staged drying operation will greatly occupy the area of ​​the workshop and require staff to frequently walk in front of large equipment, which greatly reduces work efficiency.

When the servo motor 9 is started, the output shaft of the servo motor 9 drives the winding drum 11 to rotate clockwise, which can perform the winding treatment of the processed sublimation transfer paper. The temperature controller 3 is connected to the electric heater through wires. Heat pipe 21 is electrically connected. The sublimation transfer paper to be dried enters the first tank 14 through the feed port on the left side of the first tank 14, and is guided and conveyed by guide roller 23.

During the pre-drying process, the first pneumatic butterfly valve 17 and the first centrifugal fan 18 can be activated. A high-humidity environment is created upon initial contact of the wet paper, and the moisture can be quickly removed by the first centrifugal fan 18. To maintain ambient humidity while pre-drying the sublimation transfer paper, the sublimation transfer paper, after being processed in the pre-drying tank 5, sequentially enters the third tank 24, which is arranged in a ring at equal intervals. The paper is then conveyed between the third tanks 24 via an arc-shaped feeding tube 25. The paper is fed sequentially onto heating rollers 34 inside the third tank 24. The electric heating wires 35 inside the heating rollers 34 are electrically connected to a temperature controller 3 via wires, controlling the temperature inside the third tank 24 to increase in a stepped manner. The temperature is controlled to increase gradually via the arc-shaped feeding tube 25. During the internal material feeding process, the humidity sensor 32 can monitor the humidity of the surface of the conveyed sublimation transfer paper in real time. If the humidity does not reach the appropriate standard, the water injection pipe 29 can be connected to the external water pump equipment and clean water can be injected into the arc-shaped water supply pipe 30. Then, water mist is sprayed into the corresponding arc-shaped material supply square pipe 25 through the atomizing nozzle 31 and comes into contact with the sublimation transfer paper. The humidity can be dynamically compensated during the drying process. In addition, the drying tanks 6 arranged in a ring at equal intervals do not occupy a large area, making it convenient for staff to operate and inspect them uniformly.
