Preferably, the mixing mechanism is provided with 3;

[0018] Specifically, each mixing mechanism includes a vertically arranged mixing tank 1, a vertically arranged mixing shaft 2 is installed in the mixing tank 1, the bottom of the mixing shaft 2 is rotatably installed at the bottom of the mixing tank 1, the top of the mixing shaft 2 penetrates the top of the mixing tank 1 from the inside to the outside, and extends to the outside of the mixing tank 1, a rotary dynamic seal is installed at the junction of the mixing shaft 2 and the mixing tank 1, a driving device 4 for driving the mixing shaft 2 to rotate is installed on the mixing tank 1, and a stirring rod 3 is installed on the mixing shaft 2 in the mixing tank 1; the driving device 4 is used to drive the mixing shaft 2 to drive the stirring rod 3 to rotate in the mixing tank 1, so as to achieve stirring and mixing of the PVC and PVC processing aids entering the mixing tank 1, and ensure the mixing effect;

Three stirring rods 3 are arranged on each mixing shaft 2, and the three stirring rods 3 are respectively arranged at the lower part, the middle part and the upper part of the mixing shaft 2;

[0020] In order to ensure the reliability of the installation of the mixing shaft 2 and the mixing tank 1, a sealing cover 5 is installed at the bottom of the mixing tank 1, the bottom of the mixing shaft 2 is inserted into the sealing cover 5, and is installed on the mixing tank 1 in the sealing cover 5 through a bearing and a bearing seat, and a rotary dynamic seal 6 is also installed at the junction of the sealing cover 5 and the mixing shaft 2, so that the junction of the mixing shaft 2 and the bottom of the mixing tank 1 can be isolated to avoid being blocked by the materials in the mixing tank 1, and ensure that the mixing shaft 2 can work normally and stably;

[0021] In order to realize the feeding and discharging operation of the mixing tank 1, a feed port I7 and a feed port II8 are respectively arranged on both sides of the top of the mixing tank 1, and a discharge pipe I9 and a discharge pipe II10 are connected at the bottom of the mixing tank 1. In two adjacent mixing mechanisms, the discharge pipe I9 of the mixing tank 1 of the previous mixing mechanism is connected with the feed port I7 of the mixing tank 1 of the next mixing mechanism. The feed port I7 is used for feeding PVC or one of the PVC processing aids, the feed port II8 is used for feeding another PVC processing aid, the discharge pipe I9 is ​​used to feed the discharge of the mixing tank 1 of the previous mixing mechanism into the mixing tank 1 of the next mixing mechanism, so as to continue to add different PVC processing aids for mixing operations, and the discharge pipe II10 is used to directly output the PVC product obtained by mixing in the mixing tank 1;
