[0019] As Figures 1-4 shown, the abrasive belt polishing machine of the present invention includes a frame 01, and two sets of first polishing mechanisms 02 and second polishing mechanisms 03 with the same structure are symmetrically arranged on one side of the frame 01. The first polishing mechanism 02 and the second polishing mechanism 03 are provided with a gap for placing the workpiece. On the other side of the frame, there is a driving mechanism for synchronously driving the first polishing mechanism 02 and the second polishing mechanism 03 to work synchronously.

[0020] The paste application device 04 automatically applies polishing paste to the polishing mechanism at intervals. It is more efficient and more evenly applied than the traditional manual application of polishing paste on the workpiece.

[0021] The first polishing mechanism 02 includes two adjusting devices 05 fixedly installed on the frame, and a tensioning assembly 06 located between the two adjusting devices 05. The two adjusting devices 05 are located on one side of the frame, and the tensioning assembly 06 is located on the other side of the frame. A first pulley 07 is arranged on one of the adjusting devices 05, a second pulley 08 is arranged on the other adjusting device 05, a tensioning wheel 09 is rotatably installed on the tensioning assembly 06, and an abrasive belt 26 is sleeved on the first pulley 07, the second pulley 08, and the tensioning wheel 09.

At the bottom of the sliding groove 11, a number of threaded holes are arranged in a "one" shape. A connecting plate 12 is slidably connected in the sliding groove 11. When it is necessary to adjust the position of the connecting plate 12 in the sliding groove 11, a thrust is applied to the connecting plate 12 to move the connecting plate 12 in the sliding groove 11. After moving to the set position, the connecting plate 12 is fixed by passing a fastener through the connecting plate 12 and connecting it to the threaded hole at the bottom of the sliding groove 11. The first pulley 07 is arranged on the connecting plate 12. Thus, the tightness of the abrasive belt 26 is adjusted.

[0023] As Figure 3 shown in the figure, the tensioning assembly 06 includes a support base 13 fixedly installed on the frame. A first cylinder 14 is fixedly installed on the support base 13.

One end of the driving shaft 16 passes through the bearing seat 17 and extends outside the bearing seat 17. The driving shafts 16 on the first polishing mechanism 02 and the second polishing mechanism 03 are adjacent to each other.

[0025] The driving mechanism includes a driving motor 18 fixedly installed on the frame and two belt pulleys 19 with the same structure. One of the belt pulleys 19 is fixedly connected to the driving shaft 16 on the first polishing mechanism 02, and the other belt pulley 19 is fixedly connected to the driving shaft 16 on the second polishing mechanism 03. The two belt pulleys 19 are drivingly connected to the output end of the driving motor 18 by a V-belt 20.

[0026] As Figure 2 shown in the figure, the paste applying device 04 includes a connecting seat 21 fixedly installed on the frame. A second cylinder 22 is fixedly installed on the connecting seat 21. The output end of the second cylinder 22 is arranged perpendicular to the abrasive belt 26. A receiving shell 23 is fixedly installed at the output end of the second cylinder 22. A third cylinder 24 is fixedly installed in the receiving shell 23. A clamping plate 25 is fixedly installed at the output end of the third cylinder 24. The clamping plate 25 and the inner wall of the receiving shell 23 form an installation chamber for placing the polishing paste. The output end of the second cylinder 22 extends and retracts to apply the polishing paste to the abrasive belt 26. The third cylinder 24 is used to fix the polishing paste.
