There is a discharge port on the right side, which contains hidden grooves, hidden buckles and bolts inside for easy adjustment and fixation. There is a second chassis on the top, and the feed port and the filter form a snap-fit ​​structure to filter impurities in the raw materials and facilitate the replacement of the filter. The overall design is intended to improve the quality and efficiency of cable material production;

[0004] However, when the patent is in use, the stirring efficiency of the stirring rod is low, thereby affecting the processing efficiency of the equipment.
