[0002] Printing is a technology that transfers the ink from the original manuscripts such as text, patterns, photos, etc. to the surface of paper, fabrics, packaging bags, etc. through processes such as plate making, ink testing, and pressurization, so as to batch reproduce the original contents. After printing, the printed materials need to be dried to ensure the printing effect.

[0003] According to a printing drying device with application number 202021440816.3, the mounting groove is opened on the table board, the two rotating rods are symmetrically mounted in the mounting groove, the two rollers are fixedly mounted on the corresponding rotating rods, the motor is fixedly mounted on the table board, and the output shaft of the motor is fixedly connected to one of the rotating rods, the conveyor belt is rotatably sleeved on the two rollers, and the printed parts can be transported. The drying mechanism is arranged on the top of the table board, and the printed parts can be preheated to avoid direct blowing of hot air.

[0004] However, the above-mentioned drying device for printing has certain shortcomings. After drying, the hot air is directly discharged from the device, which leads to waste of heat source and cannot recycle the heat in the hot air after drying. Therefore, it is always necessary to heat the device through the heating plate, which consumes a lot of energy. In addition, when the device conveys the printed matter to the drying mechanism for drying through the conveyor belt, it cannot fix and press the printed matter on the conveyor belt, which can easily cause the printed matter to deviate and cause damage to the printing machine. For this reason, we propose a drying device for printing. Utility Model Content

[0013] 1. The drying device for printing is coordinated by a partition plate, an air inlet channel, a heat exchange plate, a blow hood, an air duct, an air outlet, a mounting plate and a heating tube. After the printed piece is dried by hot air, the hot air can enter the air inlet channel to exchange heat with the heat exchange plate, thereby recycling the heat, and the hot air is drawn out through the air duct and the air duct and introduced into the drying box for drying, realizing hot air circulation, effectively utilizing the heat in the hot air after drying, thereby reducing energy consumption.
