A corrugated metal sheet member fabrication system comprising:
- a material feeder, a roller-ramming unit, a cutting unit, a conveyer, and a finished product receiving rack, said material feeder being adapted to feed a metal sheet material to said roller-ramming unit, said roller-ramming unit being adapted to roller-ramming a metal sheet material into a corrugated metal sheet material, said cutting unit comprising a base having two sliding rails and a reciprocating cutting-off device supported on said base and adapted to cut each corrugated metal sheet material received from said roller-ramming unit into finished products of a predetermined size, the reciprocating cutting-off device having a bottom wall and a rear side, a screw transmission mechanism being configured to drive the reciprocating cutting-off device forwards/backwards along the two sliding rails, said conveyer comprising a belt frame and a conveying belt supported on said belt frame and adapted to deliver the finished products from said reciprocating cutting-off device to said finished product receiving rack, said reciprocating cutting-off device of said cutting unit having two sliding grooves arranged in parallel on the bottom wall thereof and respectively coupled to the two sliding rails at the base of said cutting unit,
- wherein:
- two movable frames having rear ends are respectively slidably arranged in parallel along two opposite sides of said belt frame of said conveyer, each having a front end respectively connected to the rear side of said reciprocating cutting-off device of said cutting unit;
- a front driven roller is pivotally connected between the front ends of said movable frames;
- a rear driven roller is pivotally connected between the rear ends of said movable frames;
- said belt frame of said conveyer has a driven roller pivotally provided at a front side thereof and spaced between the front driven roller and rear driven roller at said movable frames at an elevation above the front driven roller and rear driven roller at said movable frames;
- said conveying belt of said conveyer extends over the driven roller at the front side of said belt frame, the front driven roller and rear driven roller at said movable frames, and a driving roller at a rear side of said belt frame;
- a driving roller is pivotally provided at the belt frame of said conveyer and a transmission mechanism configured to rotate the driving roller to move said conveying belt in carrying the finished products from said reciprocating cutting-off device to said finished product receiving rack;
- when said reciprocating cutting-off device of said cutting unit is moved forwards and backwards, said movable frames are moved synchronously, and therefore said conveying belt is moved with said movable frames forwards to an extended position and backwards to a retrieved position;
- when said movable frames are moved forwards, a front side of said conveying belt is kept spaced above the base of said cutting unit for receiving the finished products from said reciprocating cutting-off device and delivering collected finished products to said finished product receiving rack.
