One end of one of the installation cylinders is provided with a motor, and the output shaft of the motor is fixedly connected with the rotating shaft of one of the spiral conveying mechanisms.

[0004] In the above related technology, the following defects exist: the core layer master batch and the skin layer master batch are heated in the two installation cylinders respectively, and then discharged into the barrel for mixing. Not only is the equipment too complex and the cost is high, but also a large amount of molten core layer master batch and skin layer master batch will adhere to the installation cylinder when the molten core layer master batch and skin layer master batch are discharged into the barrel, which not only causes waste, but also affects the mixing ratio and quality. SUMMARY
