Description

Technical Field

[0001] The utility model belongs to the technical field of plywood waste crushing, and particularly relates to a plywood waste crushing device. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by slicing wood segments into veneers or planing wood squares into thin woods and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture. During the production process of plywood, a large amount of waste is generated.

[0003] Publication (Announcement) Number: CN218924814U. The utility model belongs to the technical field of waste crushing and recycling equipment, and particularly relates to a plywood waste crushing and recycling device, including a crushing box.
