Description
[Technical field]
[0001] The utility model relates to the field of wood board processing, in particular to a wood board cleaning device. [Background technology]
[0002] Paint board is a common thermal transfer product, which mainly uses a thermal transfer machine to print patterns and text on the surface of the wood board. During the thermal transfer process, the wood board will contact the thermal transfer film and thermal transfer paper in the thermal transfer machine, so that the pattern and text are transferred to the surface of the wood board. Before thermal transfer, the wood board needs to be cleaned to remove surface dirt, make the surface of the wood board clean, and improve adhesion.
[0003] Currently, the cleaning of wooden boards is mainly done by brushing with multiple high-speed rotating brushes. However, since the linear speed of the outer circle of the brush is greater than the linear speed of the inner circle of the brush, the surface of the wooden board brushed by the brush is brushed to different degrees and unevenly, which may cause uneven adhesion on the surface of the wooden board and affect the aesthetics of the subsequent painted board after thermal transfer. For example, after long-term use, the paint on the painted board will fall off unevenly. [Contents of the utility model]
