[0020] The fixed grinding structure includes: a support plate 5, four first electric push rods 6, two adjustment frames 7, six adjustment rods 8, six adjustment bolts 9, two pressing frames 10 and a grinding assembly;

[0021] The two ends of the support plate 5 are respectively connected to the two sides of the mounting frame 1 and are located at the upper end of the conveyor belt 4. The four first electric push rods 6 are respectively installed on the walls on both sides of the mounting frame 1. The two adjustment frames 7 are respectively installed on the telescopic ends of the four first electric push rods 6. One ends of the six adjusting rods 8 are respectively movably embedded in the two adjusting frames 7. The six adjusting bolts 9 are respectively movably embedded in the upper walls of the two adjusting frames 7. One ends of the two clamping frames 10 are respectively connected to the other ends of the six adjusting rods 8. The grinding assembly is fixedly installed on one side of the mounting frame 1.

[0022] When polishing the leather, the staff first adjusts the positions of the six adjusting rods 8 in the adjusting frame 7 according to the specifications of the leather, changes the overall spacing of the two clamping frames 10, and then fixes the adjusting rods 8 by adjusting bolts 9. The staff then replaces the grinding roller 18 in the polishing assembly.
