Description

Technical Field

[0001] The utility model relates to the technical field of artificial board production, in particular to an artificial board surface cleaning device. Background Art

[0002] Wood-based panels are made from wood or other non-wood plant materials. After mechanical processing, they are separated into various component materials and then bonded together with or without adhesives and other additives. These primarily include three categories: plywood, particleboard, and fiberboard. Hundreds of further products and further processed products are also available.

[0003] During the production of artificial boards, their surfaces need to be veneered. However, after veneer processing, the veneer often has problems such as loose adhesion and easy falling off, which affects the quality of the product. After observation and analysis, there are several main reasons for this phenomenon: 1. After the board is sawed, the suction pipe cannot completely remove all the dust and sawdust generated after sawing, resulting in some dust and sawdust remaining on the board surface, causing the veneer on the edge of the board to be loose. 2. When the products are stacked, the sawdust left on the board surface presses a pit on the bottom of the board panel. According to the above analysis, the surface of the artificial board needs to be cleaned before veneer. The current cleaning device usually sets a cleaning roller above the board, and the cleaning roller rotates to clean the surface of the board, but sometimes sawdust will adhere to the cleaning roller. During the cleaning process, the sawdust will scratch the surface of the board, affecting the subsequent veneer effect. The existing cleaning device needs to be improved. Utility Model Content
