The extruder barrel cooling system forms a circulating operation of the refrigeration system through the mutual cooperation between multiple cooling jackets, inlet and outlet water pipes, and a control center, and does not form scale on the outer wall of the barrel, thereby improving the refrigeration efficiency of the cooling device and reducing production costs. However, in the cooling system, each cooling jacket has only one water inlet and one water outlet. According to the law of liquid flow, the closer to the water inlet and the water outlet, the faster the flow rate of the liquid, and the farther away from the water inlet and the water outlet, the slower the flow rate of the liquid, so the cooling effect of the middle part of the cooling jacket is better, while the cooling effect of the two sides of the cooling jacket is poor, which makes the temperature of each position of the barrel in the cooling jacket inconsistent, increasing the difficulty of temperature control.

[0003] Therefore, it is necessary to propose a cable material extruder barrel to solve the above problems. Utility Model Content
