Description

Technical Field

[0001] The utility model belongs to the technical field of paper-faced gypsum boards, and particularly relates to a drying device for producing impact-resistant paper-faced gypsum boards. Background Technique

[0002] A paper-faced gypsum board is a building material mainly made of building gypsum. After adding fibers, additives and appropriate light fillers, it is mixed with water to form a slurry, which is then poured on paper and covered with an upper layer of paper. Its main use is as an interior partition wall and ceiling material in buildings. An impact-resistant paper-faced gypsum board is a building material that improves its impact resistance by improving materials and processes on the basis of ordinary paper-faced gypsum boards.

[0003] A patent with the publication number CN215766318U in the prior art relates to a drying device for producing paper-faced gypsum boards, including a box body.

A driving roller is also provided in the box body, and multiple driving rollers are evenly arranged at the geometric center of the box body and span the front and rear inner walls of the box body.

[0004] Through the pressing device in the above solution, the surface of the paper-faced gypsum board can be pressed, thus effectively reducing the possibility of deformation of the paper surface of the paper-faced gypsum board. However, when the paper-faced gypsum board is dried, it is pressed by the pressing device and is in a static state. This makes it difficult for the high-temperature air flow blown by the blowing device to dry the inside of the paper-faced gypsum board, thereby reducing the drying effect of the drying device.
