Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, and specifically relates to a high-buffered barrier packaging paper production drying device. Background Technology

[0002] High-barrier packaging paper typically has a multi-layered structure, mainly including an outer linerboard, a sandwich linerboard or honeycomb paper core, an EVA foam cushioning layer or other cushioning materials, and a bottom linerboard. These layers are tightly bonded together through specific processes to form a packaging paperboard structure with high strength, high cushioning performance, and good barrier properties. High-barrier packaging paper usually requires drying treatment using a microwave paperboard dryer during the production process.

[0003] Currently, in existing microwave cardboard dryers, the packaging cardboard to be dried is placed on the conveyor belt of the machine frame and then transported to the drying area of ​​the microwave dryer. Since the packaging cardboard is placed on the conveyor belt of the drying device, cardboard fragments and paper dust will also adhere to the conveyor belt. The paper dust will also enter the machine with the conveyor belt. Once it accumulates too much, it will affect the use and be extremely inconvenient to clean. Utility Model Content
