Description

Technical Field

[0001] This utility model relates to the field of wood board edge scraping technology, and in particular to a glue scraping device and a wood board edge banding machine. Background Technology

[0002] During operation, the edge banding machine uses a scraper to scrape the sides of the board. A common problem during the scraping process is that as the board moves, the wood fibers produced after scraping can get stuck between the edge banding wheel and the part of the board to be processed, causing the edge banding wheel to bounce and seriously affecting the subsequent processing quality of the board.

[0003] Therefore, CN202020975233.4 discloses a scraping and blowing structure for an edge banding machine. The wood fibers generated when scraping the edge of the board are designed according to the direction of the air outlet. Under the action of airflow, the wood fibers will not get stuck between the first edge banding wheel / second edge banding wheel and the board, effectively avoiding the jumping problem of the first edge banding wheel / second edge banding wheel and ensuring the scraping and edge banding quality of the board.

[0004] However, directly blowing away the filaments through the air blowing structure still has many problems. After being blown out by the airflow, the landing point of the filaments is not fixed, making subsequent cleaning more troublesome. In addition, the automatic edge banding machine consists of multiple continuous workstations. Tiny flying debris generated by other workstations will drift to a farther location after being blown away by the air blowing structure, affecting the surrounding hygiene. Utility Model Content
