Description

Technical Field

[0001] This utility model relates to the field of paper drying technology, and in particular to a high-efficiency paper dryer with alternating double-sided drying. Background Technology

[0002] The development of the high-efficiency double-sided alternating paper dryer stems from the efficiency bottlenecks and paper quality defects inherent in traditional single-sided drying technology. In the printing, packaging, and other paper processing fields, single-sided drying easily leads to uneven heating of the paper, causing warping, deformation, or moisture residue, affecting subsequent printing accuracy and finished product strength. Simultaneously, a single drying process prolongs the production cycle and increases energy consumption. In recent years, with increasingly stringent environmental regulations and rising production capacity demands, the industry urgently needs innovative equipment that can simultaneously achieve uniform heating on both sides, shorten drying time, and reduce energy consumption.

[0003] Existing application number CN201921299826.7 proposes a paper dryer for easy paper conveying, including a drying chamber and a paper conveying mechanism; the paper conveying mechanism includes a drive shaft and a driven shaft, with a drive gear sleeved on the drive shaft and a driven gear sleeved on the driven shaft; paper is placed in a mesh tray, and the paper passes through the drying chamber through the paper inlet and paper outlet; the bottom of the drying chamber is connected to a heat exchange chamber, with an air inlet on the side of the heat exchange chamber and a heat exchange tube inside the heat exchange chamber; the air outlet of the exhaust fan is connected to the drying chamber in sequence through a first pipe and a second pipe; the top of the drying chamber is connected to the exhaust fan through an exhaust pipe, and the air outlet of the exhaust fan enters the drying chamber through a return air pipe to form a closed loop. This paper dryer, which facilitates paper transport, ensures stable paper transfer. It uses hot air generated by heat exchange between air and heat exchange tubes in the heat exchange chamber to dry the paper and recovers the hot air back to the drying box, reducing energy consumption and saving production costs. However, the existing technology still has the problem of uneven drying effect on both sides of the paper, making it difficult to achieve simultaneous and efficient drying on both sides. This can easily lead to deformation or wrinkling of the paper due to overheating on one side. Furthermore, manual intervention is required to collect the paper after drying, resulting in poor production continuity. Utility Model Content
