Description

Technical Field

[0001] This utility model relates to the field of plywood coating technology, specifically to an environmentally friendly coating device for plywood veneer. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with the fiber directions perpendicular to each other.

[0003] In the prior art, a plywood adhesive coating device with publication number CN218982142U includes a frame, on which are arranged a conveyor belt assembly for traction of plywood movement, a coating unit for applying adhesive to the plywood, and a scraping unit for evenly distributing the adhesive on the plywood and recovering excess adhesive. The scraping unit is located on the side of the coating unit away from the feed end of the conveyor belt assembly, and at least two scraping units are arranged along the conveying direction of the conveyor belt assembly. The scraping unit includes a linear module one and a linear module two. A scraper is provided at the bottom of the slide two in the linear module two. The scraping unit also includes a scraper body. The scraper body and the linear module one are located on opposite sides of the conveyor belt assembly, respectively. The scraper body has a through scraping groove on its side along the width direction of the conveyor belt, and the scraping groove also extends to the side of the scraper body facing the discharge end of the conveyor belt assembly. The shape of the scraping groove matches the shape of the horizontal plate.

[0004] Compared to the existing technology that uses a pump structure to collect excess glue, the above-mentioned plywood glue coating device has a simpler structure, lower cost, and lower energy consumption. Moreover, since there are at least two sets of scraping units, multiple sets of scraping units can be used alternately. Each time one or more plywoods are passed, the scraping unit scrapes off the glue on the horizontal board with a scraper, and the glue coating process of the plywood does not need to be stopped. However, in the above-mentioned technology, the device can only coat one side of the plywood, which is quite limited. In addition, the scraping unit of the device cannot recycle the scraped glue, which is wasteful.

[0005] In summary, we provide an environmentally friendly coating device for plywood veneer. Utility Model Content
