Description

Technical Field

[0001] The utility model relates to the field of paper tray manufacturing equipment, and particularly relates to a paper tray quality inspection rack with an interlayer structure. Background Art

[0002] In the paper product production industry, as a common packaging material, paper trays are widely used for the packaging and protection of various products due to their tough texture and strong compressive strength. However, with the continuous growth of market demand, the requirements for the quality of paper trays are becoming increasingly strict. In order to ensure the consistency and stability of paper tray products during the production process, the quality inspection link is particularly important. Against this background, the paper tray quality inspection rack has emerged.
