Quality detection device for production of strawboards

The invention relates to the field of paperboard production, in particular to a quality detection device for production of strawboards, which comprises a detection frame. Two pieces of transparent glass are arranged in the detection frame at equal intervals, a [-shaped mounting frame is arranged above each piece of transparent glass, and paper is conveyed in the detection frame in a [shape and is attached to the surface of the corresponding transparent glass; an appearance marking mechanism for marking paper appearance defects is arranged in each [-shaped mounting frame; the two appearance marking mechanisms are used for detecting and marking the thickness of the paperboard and appearance defects of the two faces of the paperboard, so that the labor intensity of workers is reduced, the paperboard detection efficiency is improved, and the product production quality is ensured. 本发明涉及纸板生产领域，具体是涉及一种黄纸板生产用质量检测装置，包括检测框；检测框内部等距设置有两个透明玻璃，每个透明玻璃上方设置有匚形安装架，纸张在检测框内呈匚形形状进行输送并且贴合对应透明玻璃表面；每个匚形安装架内均设置有用于对纸张外观缺陷进行标记的外观标记机构；通
