However, the existing technology relies on the cutting machine to cut the bar stock. The length of the bar stock cut by the cutting machine is fixed and cannot be adjusted each time, which greatly wastes the bar stock and has low adaptability. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a bar sawing device that can change the cutting length of the bar, improve the utilization rate of the bar, and has high adaptability.

[0004] To solve the above problems, the present invention adopts the following technical solution:

The waste discharge outlet 91 is connected to the bottom of the front side of the waste discharge trough 9.

[0036] In this design, the transmission driver drives the front transmission wheel to rotate. The rotation of the front transmission wheel causes the transmission belt to move, which in turn moves the connecting piece along the through hole. This movement of the connecting piece causes the cutting seat to slide back and forth along the slide rail assembly, moving it to a preset position. The bar stock to be processed is then fed into the clamping module through the feed inlet. The bottom of the bar stock is supported by two cutting rollers. The clamping block driver drives the right clamping block to approach the corresponding left clamping block, clamping the bar stock between the left and right clamping blocks. Then, the extension and retraction of the second drive cylinder... The end-driven cutter head support descends, causing the cutting blade on the cutter head support to saw the bar stock to be processed. After sawing, the transmission drive drives the cutting seat to move backward, so that one end of the bar stock clamped by the clamping mechanism located on the rear side is conveyed between the feeding roller and the feeding drive wheel. The extension end of the first drive cylinder drives the connecting seat to descend, so that the feeding drive wheel on the connecting seat contacts the bar stock on the feeding roller. The clamping mechanism located on the rear side releases the bar stock, and the second drive device drives the feeding drive wheel to rotate, so that the feeding drive wheel sends the bar stock out through the feeding port.

[0037] During bar stock processing, debris is generated. The debris falls into the waste discharge trough at the bottom. Since the waste discharge trough slopes downward from back to front, the debris is discharged through the waste discharge outlet along the slope.

[0038] After a long period of operation, the transmission belt may become loose. By rotating the threaded adjusting rod, the threaded adjusting rod drives the slide block to move backward along the slide groove, causing the transmission wheel inside the slide block to move backward, so that the two transmission wheels tighten the transmission belt.
