一种贵金属刺绣针防过热机构
By embedding a heat-conducting component inside the embroidery needle shaft and installing an air-cooling component in the gap between the needle shafts, the problem of overheating due to friction in embroidery needles is solved, achieving effective cooling of the needle tip and tail, preventing needle tip deformation, and ensuring the stability and lifespan of the embroidery needle.

AI Technical Summary
During the high-intensity production process of embroidery machines, the embroidery needles overheat due to frequent contact and friction with the fabric. The heat concentrates at the needle tip, causing the needle tip to bend and deform, which in turn exacerbates friction and heat generation, creating a vicious cycle.
A heat-conducting component is embedded inside the embroidery needle shaft, and an air-cooling component is installed in the gap between the needle shafts. The heat-conducting component is used to conduct heat from the needle tip to the tail, and the air-cooling component is used to cool the entire needle shaft, including the needle tip and the tail, thereby forcibly cooling and dissipating heat.
It effectively avoids overheating and deformation of the needle tip, and ensures that heat does not accumulate at the needle tip and tail through a dynamic cooling path, thus maintaining the stability and service life of the needle shaft.
