Description

Technical Field

[0001] This utility model relates to the field of paper product technology, and in particular to a paper product processing device. Background Technology

[0002] Chinese Patent CN221118089U discloses a paper product processing equipment. Specifically, it discloses a method where a heater heats the air inside a blower box. A fan rotates, causing the air inside the blower box to flow upwards, allowing the hot air to enter a sealed space above the drum plate, thus heating the paper surface. A motor drives fan blades to rotate, allowing the moisture evaporated from the paper to escape from the sealed space. This design, by creating a sealed drying space, effectively reduces heat loss in the drying device. The paper-wound drum is placed in two placement slots. By sequentially flipping up cover plates one and two, the free end of the paper rests on two conveyor rollers at the top of the drum plate. The paper is then covered with cover plate one and cover plate two, causing the two conveying rollers at the bottom of cover plate one and cover plate two to squeeze the paper. This design facilitates the installation of the paper. In the above patent, because hot air enters unidirectionally through the air inlet hole at the bottom of the tube plate, there is a lack of uniform airflow design, which leads to uneven heating of the paper and may produce local over-drying or under-drying areas. In addition, the filter screen is located on the inner wall of cover plate two, and its cleaning mechanism is not clearly defined. It is easily clogged by paper scraps, reducing the dehumidification efficiency. The roll paper is placed in the U-shaped placement groove, and during winding, it is driven by motor one to drive shaft one. There is a lack of tension adjustment mechanism, which easily leads to paper wrinkling and breakage. Therefore, there is an urgent need for a paper product processing device that can solve the problems of uneven heating of paper, avoid filter screen clogging and inaccurate paper tension control.
