[0024] It also contains:

[0025] The motor 4 is fixedly arranged in the feeding pipe 1 by bolts, a spiral feeding rod 5 is fixedly arranged on the output shaft of the motor 4, and the left end of the spiral feeding rod 5 is screwed and arranged on the left inner wall of the feeding pipe 1 through a bearing, a baffle 12 is fixedly arranged in the feeding pipe 1 at the right side of the feeding pipe 3, and the output shaft of the motor 4 is screwed and penetrated on the baffle 12 through a bearing, and the baffle 12 can provide protection for the motor 4 to prevent the masterbatch and auxiliary materials from contacting the motor 4, and heat dissipation ports 13 are provided on the side wall of the feeding pipe 1 at the front and rear sides of the motor 4, which are conducive to timely dissipating the heat of the motor 4 in the feeding pipe 1, and avoiding the motor 4 from triggering automatic protection due to overheating, and a dust cover 14 is fixedly arranged on the side wall of the feeding pipe 1 at the outer side of the heat dissipation port 13 by bolts, so as to reduce the external dust and other impurities from falling into the feeding pipe 1 and causing adverse effects on the operation of the motor 4;

[0027] A fixing frame 10, wherein the fixing frame 10 is fixedly arranged in the feeding pipe 1 by means of bolts, the right end of the spiral feeding rod 5 is screwed and penetrated on the fixing frame 10 by means of a bearing, and a synchronous driving stirring mechanism 11 is arranged on the fixing frame 10;

[0028] The synchronous drive dispersing mechanism 11 comprises:

[0029] The driving rod 11-1 is screwed through the upper side wall of the fixed cylinder 6 through a bearing, the lower end of the driving rod 11-1 is connected to the rotating cylinder 7, the upper end of the driving rod 11-1 is screwed through the bearing and inserted on the fixed frame 10, and the driving rod 11-1 is transmission-connected to the spiral feeding rod 5 through a bevel gear pair;
