Description

TECHNICAL FIELD

[0001] The utility model relates to paper processing technical field, concretely relates to a drying and pressing device for paper processing. BACKGROUND

[0002] Paper is a kind of sheet material made of plant fiber, and is widely used in writing, printing, packaging and other fields. Its main raw materials include wood pulp, straw pulp and waste paper pulp, among which wood pulp is the most commonly used raw material. Paper has the characteristics of lightness, softness and strong plasticity, and has certain environmental protection due to its recyclability. As an important basic material, paper plays an indispensable role in modern society. In the papermaking process, pressing and drying are two crucial process steps, which directly affect the quality and performance of paper. The main purpose of pressing is to remove water from paper and improve the density and flatness of paper. In the prior art, such as the paper processing drying and pressing equipment disclosed in Chinese Utility Model Publication No. CN210262492U, the transmission mechanism, pressing mechanism and drying mechanism are installed on the rack, the transmission mechanism includes a conveyor belt, a transmission motor and a transmission shaft, the transmission shaft is rotatably connected to the rack, and the conveyor belt is sleeved on the outer surface of the transmission shaft. The second air cylinder controls the abutment block to start descending and contact with the paper placed in the inside of the placing disc. Since the abutment block is located in the drying box, the abutment block is irradiated by the heat lamp for a long time, thereby improving the temperature of the abutment block itself. When the abutment block contacts the paper, the paper in the placing disc is dried by the temperature of the abutment block itself. Under the control of the second air cylinder, the abutment block is in close contact with the paper, which can further improve the drying degree of the paper and indirectly improve the quality of the finished paper, avoiding the incomplete drying of the paper.

[0003] The use of placing disc to carry paper, the paper pulp will cause blockage in the water collecting tank during the pressing process, resulting in poor drainage effect or liquid overflow, affecting the pressing effect of paper. During the paper drying process, the drying mechanism can only dry the front surface of the paper, and the back surface of the paper is in the drying blind area, which can easily cause the back surface of the paper to be still wet after the paper drying process is completed, affecting the quality of the finished paper.
