The taking assembly 3 is installed on the fixed-length servo assembly 4 and can be detached.

[0033] After loading, the feeding assembly 1 holds the workpiece to keep it stable, and the sawing assembly 2 moves downward to cut the end of the workpiece and then resets. Then the cycle begins: the feeding assembly 1 feeds forward by a certain distance, the taking assembly 3 holds the workpiece, the feeding assembly 1 releases the workpiece, the taking assembly 3 pulls the workpiece backward by a fixed length under the traction of the fixed-length servo assembly 4, the feeding assembly 1 clamps the workpiece to keep it stable, and the sawing assembly 2 moves downward to cut the workpiece and then resets. After a workpiece of a specified length is cut, it is blown off to the collection part, the fixed-length servo assembly 4 resets, the feeding assembly 1 resets and holds the workpiece, and a new cycle begins. When the fixed-length servo assembly 4 pulls the workpiece backward by a fixed length, the sensor placed in front of the sawing assembly 2 cannot detect the workpiece, and the remaining workpiece length is not enough to cut a finished product. At this time, the waste will be put into the waste box.
