Problems solved by technology

[0004] The above-mentioned prior art uses a drying box to dry paper, but the paper that has not yet entered the drying box and the paper that has entered the drying box often cause wrinkles on the dried paper due to the large dry-wet difference, resulting in The quality of the paper surface after drying is reduced, and the above-mentioned prior art utilizes the filter screen to intercept and filter the ink particles, so that when the filter screen intercepts a certain amount of ink particles, the interception effect will be lost. At this time, the filter screen needs to be replaced. Such an operation is very cumbersome

Abstract

The invention relates to the technical field of printing, in particular to an environment-friendly printing drying device. The environment-friendly printing drying device comprises a drying chamber, a hot air box, an air inlet pipe, a drying box, a condensation water collector, a circulating pipeline, a first pressure pump, a filter box, a heat exchanger, a second pressure pump, a first stop valve and a second stop valve. The drying force is gradually increased in the paper moving direction, so that wrinkles on the surface of the paper caused by shrinkage of the paper inside and outside the drying chamber due to the too large dry-wet difference are avoided, and then the surface quality of paper finished products is further improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environment-friendly printing drying device. Background technique [0002] Printing is a technology that transfers ink to the surface of paper, fabrics, plastics, leather and other materials through plate-making, ink application, and pressurization of originals such as text, pictures, photos, and anti-counterfeiting. Printing is generally ink printing. The color of ink printing is vivid, it is not easy to fade after drying, and can be stored for a long time, but the ink of the newly printed material is not dry, so it cannot be overlapped. After overlapping, the image on the material will not only change. Will contaminate each other, making the whole material dirty or even unusable. At present, the newly printed paper products or plastic products are often spread out to dry. This method has many shortcomings. The drying speed is slow, which affects the entire processing effic...
