The cutting unit is adapted to cut the lumber into an upper piece and a lower piece. The guide unit includes two guide rollers mounted to the hood body, extending into the outlet passage, and adapted to separate the upper piece from the lower piece. The cleaning unit includes an air lance for directing an air stream to the conveyor belt.
Claims13
A band saw machine for cutting a lumber, said band saw machine comprising:
- a frame body unit including a support frame module and a cleaning hood module, said support frame module having an upright base plate that is formed with an outlet port extending therethrough in a front-rear direction, said cleaning hood module including a hood body that extends rearward from said base plate in said front-rear direction, that surrounds said outlet port, and that has two first openings formed respectively in opposite sides of said hood body in a left-right direction which is perpendicular to the front-rear direction;
- a transport unit connected to said frame body unit, and including a conveyor belt that extends in said front-rear direction through said outlet port and adapted to transport said lumber from an upstream side of said outlet port which is in front of said outlet port to a downstream side of said outlet port which is behind said outlet port, said cleaning hood module cooperating with said conveyor belt to define an output passage that is communicated with said two first openings and said outlet port and that has a rear open end;
- a cutting unit connected to said support frame module, and including a first cutter module, said first cutter module including a first continuous band saw blade that has a cutting section travelling alongside said outlet port and above said conveyor belt, and that is adapted to cut said lumber into an upper piece and a lower piece;
- a cleaning unit including a first air lance that extends through one of said first openings of said hood body of said cleaning hood module for directing an air stream to said conveyor belt;
- and
- a guide unit including two upper guide rollers that are mounted rotatably on said hood body, that extend respectively through said two first openings into said outlet passage, and that are disposed in front of said first air lance, said two upper guide rollers being disposed higher than said cutting section of said first continuous band saw blade and adapted to be respectively in contact with two opposite sides of said lumber in said left-right direction to separate said upper piece of said lumber from said lower piece of said lumber.
