Dehumidifying room special for offset print corrugated package and dehumidifying method thereof

Abstract

The invention discloses a dehumidifying room special for offset print corrugated package. The dehumidifying room special for offset print corrugated package comprises a room provided with a temperature and humidity detection sensor and a single chip microcomputer controller, wherein the signal output interface of the temperature and humidity detection sensor is connected with the signal input interface of the single chip microcomputer controller, a left sealing door and a right sealing door are respectively arranged at two ends of the front side wall of the room, two dry air generators controlled by the single chip microcomputer controller are respectively arranged at two ends of the room, a strong convection fan controlled by the single chip microcomputer controller is arranged at opposite corner positions of the room respectively, a natural humidity suction air pipe is vertically and upwards arranged at the top of the room, and the front side wall or / and the rear side wall of the room is a wall provided with a large-area double-layer vacuum glass window. The dehumidifying room has the advantages that the dehumidifying room is designed for offset print corrugated carton products needed to be adhered with face paper, utilizes an air hot-cold natural convection principle, performs humidity suction on the products needing humidity suction by utilizing negative pressure produced by strong convection of dry air and accordingly is high in humidity suction efficiency and capable of saving energy and protecting environment.

Description

technical field [0001] The invention relates to offset printing corrugated packaging products, in particular to a special dehumidification room for offset printing corrugated packaging and a dehumidification method thereof. Background technique [0002] Offset printing corrugated packaging products such as corrugated cardboard, corrugated paper packaging boxes (boxes), etc., in the production process, the surface paper that has been treated on the surface must be pasted on the corrugated sheet of the selected corrugated type to make the box to be die-cut. Then the finished products of corrugated packaging boxes (boxes) are made by a fully automatic box gluer. The above-mentioned corrugated carton sheets after lamination are mounted in a wet method, which is also called a cold setting method. The semi-finished corrugated box produced in this way has a moisture content of 15-25% per square meter. Such high humidity will inevitably make the corrugated box very soft, making the...

AI Technical Summary

Problems solved by technology

At present, dehumidifiers are often used to dehumidify the moisture in offset printed corrugated products. However, when the humidity of the laminated corrugated boxes is above 15%, the dehumidification effect is basically not achieved, which not only consumes a lot of energy. Large, and a large dehumidifier dehumidifies only a few thousand qualified products a day

There is also a drying method to dehumidify the finished product, but the temperature required for drying is high, which is easy to cause product deformation, especially for products whose surface has been treated with a film, drying will cause the product to be damaged due to surface damage at any time. scrapped due to damage
