Description

Technical Field

[0001] The utility model relates to the technical field of printing and drying, in particular to a printing and drying device for paper products. Background Art

[0002] In the paper printing industry, drying is a vital link. With the continuous development of printing technology and the increasing market requirements for paper product quality and output, paper printing drying equipment is also constantly evolving. Paper printing has gradually developed from traditional manual printing to today's mechanized large-scale printing. The demand for drying equipment has also changed from simple drying functions to high efficiency, high quality, low energy consumption and other aspects. At the same time, the improvement of environmental protection requirements has also prompted continuous technological innovation in drying equipment, which must not only ensure drying effects but also reduce the impact on the environment. Various new types of paper materials and inks continue to emerge, which also puts forward higher adaptability requirements for drying equipment.

[0003] Among the existing paper product printing and drying devices, some use a relatively simple hot air drying structure, which usually generates heat through a heating source and then uses a fan to blow the hot air toward the paper products. The heating source is generally resistance wire heating or ordinary hot steam heating. During the hot air transmission process, there is a lack of effective filtering and processing structure. The air is directly extracted from the outside and heated, and then blown toward the paper products through a fixed air duct. The setting of the air outlet is mostly fixed in direction and position and cannot be adjusted.

[0004] The current paper product printing and drying technology has the problem of not effectively treating hot air. Due to the lack of filtering devices, during the drying process, dust and impurities in the air are easily attached to the surface of the paper product with the hot air flow, affecting the printing quality. Moreover, if the air contains moisture, it will directly act on the paper product and ink without treatment, which will cause uneven drying of the ink and the occurrence of blurring. At the same time, the fixed air outlet cannot adjust the direction and distribution of hot air according to the actual situation of the paper product, resulting in large differences in the heating of paper products in different areas, which in turn leads to uneven drying and affects product quality. Therefore, a paper product printing and drying device is proposed to solve the above problems. Utility Model Content

[0017] 2. In the utility model, the second electric push rod retracts to move the sliding block, and the sliding column slides in the slide groove to drive the locking plate to move downward, thereby releasing the lock on the ash filter screen and the drying screen. Then the first electric push rod pushes the push plate forward, and the push plate pushes the ash filter screen and the drying screen to move, thereby rotating the isolation door. This solves the problem that cleaning and replacing the filter screen in the past was cumbersome and time-consuming, and affected the normal operation of the equipment. It improves maintenance efficiency, ensures the continuous and stable operation of the equipment, and reduces poor drying effects and equipment failures caused by filter screen problems.
