How to adjust the sharpening speed of electric scissors in garment factory? It is better to have a picture.

I do this. I usually adjust it myself. The main adjustment is the sharpening pliers. Grind the knife to the middle to see if it is attached to the blade and there is a spring for sharpening it. It is best to remove the blade when installing the spring. But you can't adjust the spring too tightly, so the blade is not durable. Whether the wheels on both sides have left the blade body. Basically, most of them still depend on experience.
