[0004] The existing utility model realizes the cooling of the alloy drawing equipment by the double blades on the two sides of the heat sink, and the cooling effect is more obvious than that of the single copper blade, thereby eliminating the hot spot phenomenon caused by the long-term erosion of the drawing holes on the two sides of the alloy drawing equipment with long service life, and making the heat distribution of the alloy drawing equipment more uniform, but since the alloy drawing equipment has long service life and the bushing temperature required by superfine yarn is high, the 12-drawing equipment is changed to 6-drawing equipment, and since there is no special heat sink for 12-drawing superfine yarn, the space for installing the heat sink is limited, and it is impossible to independently install 12 heat sinks in the existing installation space, the yarn bundles are easily separated incorrectly during on-site yarn bundle separation, and the alloy drawing equipment heat sink is easily corroded and deformed, thereby affecting the quality of the original yarn, and it is necessary to improve. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of superfine yarn drawing cooling and separating device, its advantage is that heat distribution is more uniform, and it is convenient to carry out fixed point quick yarn separation.
