[0016] Compared with the prior art, the band saw machine blade depth cleaning steel brush mechanism has the following beneficial effects:

[0017] 1. The band saw machine blade depth cleaning steel brush mechanism can effectively avoid that the steel wire brush and the Dupont brush are too close to the saw teeth of the moving bimetallic band saw blade through accurate adjustment and limitation of the position of the mounting plate by the bolt in the limiting mechanism. When the band saw blade moves at a high speed, if the distance between the brush body and the saw teeth is too close, the saw teeth will quickly wear the bristles, so that the service life of the brush body is greatly shortened. The limiting mechanism ensures that the brush body and the saw teeth maintain a safe and reasonable distance, reduces the risk of excessive wear of the bristles, significantly prolongs the service life of the cleaning brush body, reduces the replacement frequency of the cleaning brush body, and saves the use cost.

[0018] 2. The band saw machine blade depth cleaning steel brush mechanism can realize more thorough cleaning of the saw teeth of the bimetallic band saw blade through the cooperative work of the steel wire brush and the Dupont brush. The steel wire brush has strong cleaning ability and can clean most of the residual metal chips. The Dupont brush can further finely clean the saw teeth and clean some small and difficult-to-clean metal chips. The double cleaning mode effectively solves the problem of incomplete cleaning of the single steel wire brush and avoids that the residual metal chips are brought into the sawing process again by the band saw teeth to participate in secondary sawing.
