A main transmission 25, a driving wheel 26 and a driven wheel 27 are also arranged on the saw frame 21. The main transmission 25 drives a driving wheel 26, and the driving wheel 26 drives a driven wheel 27 to run together through the band saw blade 22. A guide head 28 is also arranged on the saw frame 21. The guide head 28 serves to twist the angle of the band saw blade 22 and to guide the band saw blade 22.

The work conveying line 3 includes a movable table 31, a table base 32, a work clamp cylinder 33, and a table driving device 34. The movable table 31 moves back and forth on the table base 32. The table base 32 extends from the rear end of the band saw machine 2 across the saw frame 21 to the front end of the band saw machine 2, and the table base 32 is located below the band saw blade 22. The workpiece clamping cylinders 33 are respectively arranged on two sides of the movable workbench 31 in pairs and used for clamping the LNG marine plate workpiece to be sawed.
