AI Technical Summary
In existing technologies, the grinding of shoe soles is often inconsistent due to inaccurate manual judgment of the amount of grinding, which can easily lead to over- or under-grinding, affecting production efficiency and the quality of finished shoes.
A marking tool for shoemaking has been designed, including an opening component, a fixing component, and a pen. It uses an arc-shaped scale and a roller assembly to make precise lines. The fixing component keeps the distance between the pen and the shoe surface consistent. The arc-shaped scale is used to quickly confirm the marking position, and the roller assembly reduces friction and protects the shoe surface.
This technology enables precise marking on shoes, ensuring the accuracy and consistency of grinding positions, improving production efficiency, and avoiding quality problems in finished shoes.
