[0037] Specifically, the working principle of the automatic seal carving knife sharpening machine is as follows: when in use, the whetstone 192 is placed on the slide rail 140, the square block 153 is moved, and the two clamping blocks 155 clamp the whetstone 192, then the square block 153 is held and the first locking member 154 is rotated. The lower end of the first locking member 154 squeezes the outer wall of the guide rod 152 to fix the square block 153 on the guide rod 152, thus achieving the clamping and fixing of the whetstone 192. According to the angle between the lower end of the seal carving knife and the whetstone 192, the slider 181 is moved to adjust the slider 181. 1 on the bracket 130, hold the slider 181 after adjustment, rotate the second locking member 182, the lower end of the second locking member 182 squeezes the outer wall of the bracket 130, so that the slider 181 is fixed on the bracket 130, then put the carving knife into the slider 181, and adjust the angle between the carving knife and the grindstone 192. After adjustment, hold the carving knife and rotate the third locking member 183. The end of the third locking member 183 squeezes the outer wall of the carving knife, so that the carving knife is fixed in the slider 181, then rotate the threaded sleeve 173 to adjust The pressure between the carving knife and the grindstone 192 is then applied to the U-shaped rod 1944 on the carving knife.

At the same time, the motor 161, the first connecting rod 162 and the second connecting rod 163 are connected to the motor 161. Under the joint action of 163, the bracket 130 can move back and forth, that is, the seal carving knife can move back and forth on the whetstone 192 to grind the seal carving knife. Under the joint action of the circulating water pump 1941, the first water pipe 1942 and the second water pipe 1943, water is sprayed onto the seal carving knife to absorb the dust generated by grinding and reduce the temperature generated by the friction of the seal carving knife; the dirty water generated by grinding passes through the filter 191, the filter 191 filters out impurities in the dirty water, and the filtrate flows back to the water tank 120 to realize the recycling of water.

[0038] The automatic seal carving knife sharpening machine can automatically sharpen the seal carving knife, saving time and effort, and can control the sharpness of the seal carving knife. In addition, multiple seal carving knives can be sharpened at one time, which improves the sharpening efficiency of the seal carving knives.
