Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of board processing, in particular to a fiberboard's edge cutting and material collecting device. BACKGROUND

[0002] In the production process of fiberboard, edge cutting is needed to ensure size accuracy and edge flatness. On the one hand, edge cutting can remove irregular parts of the blank edge to ensure that the cost meets the target size; on the other hand, edge cutting can eliminate process defects such as burrs and cracks to improve the appearance and processing performance of the board; on the other hand, the cut-off corners can be recycled to reduce raw material waste.

[0003] The prior art "CN221136188U-Automatic edge cutting saw for board" discloses a scheme of cutting the blank with a saw blade. The blank of this process has been hot-pressed into a shape, and the corners have a high hardness. The traditional way to recycle the corners is to collect them and transport them to a pulverizer in another area by a conveyor belt. The above-mentioned components do not work together, resulting in a large footprint of the entire corner recycling system and the need for manual intervention in the corner collection process, which still has room for improvement in work efficiency.

[0010] As an improvement to the above solution, the column is connected to the ground by bolts, and the spacing between two adjacent columns can be changed to adjust the cutting width of the two saw blades.

[0011] This invention offers the following advantages: The suspended design of the cutting unit facilitates the addition of a crushing unit to the side of the conveyor belt. During the cutting process, large or long wood chips fall into the crushing unit, are crushed, and then removed from the site by a negative pressure unit. Simultaneously, dust generated during cutting is also promptly removed by the negative pressure unit, significantly reducing dust levels in the working environment and effectively improving the working conditions.
