[0003] Patent No. CN212472022U discloses a raw material premixing device for processing stretch film. The utility model adds the raw materials required for processing plastic film into a mixing box through two feeding pipes respectively, thereby improving the efficiency of adding materials. The added raw materials enter the mixing box through the two ends of the distribution pipe, and the added raw materials can be divided into two sides inside the mixing box to avoid the added raw materials from piling up in the same place, which is not conducive to the mixing of the raw materials. The mixing motor drives the driving shaft to rotate forward and reverse. When the driving shaft rotates, the bottom of the driving shaft drives the driven gear to rotate through the main gear, thereby driving the first vertical stirring rod and the second vertical stirring rod to rotate, the transverse stirring rod rotates in the horizontal direction, and the first vertical stirring rod and the second vertical stirring rod rotate in the vertical direction, which changes the rotation direction of the raw materials at the bottom of the mixing box, so that the raw materials inside the mixing box are mixed evenly, and the mixing speed is accelerated.

In terms of position, a plurality of guide holes 424 are provided on the mixing blade 423, and the mixing driving member 41 drives the mixing member 42 matched therewith to rotate. When the mixing driving member 41 works, it drives the two groups of mixing members 42 to work synchronously to mix the raw materials in two directions, thereby further improving the mixing effect. Specifically, the driving motor 411 drives the driving gear 412 to rotate, and at this time, the driving gear 41252 drives the mixing gears 421 on both sides to rotate. When the mixing gear 421 drives the mixing shaft 422 to rotate on the mounting frame 3, the mixing blade 423 performs the mixing operation of the wrapping film raw materials. The setting of the guide holes 424 is used to reduce the resistance generated by the mixing blade 423 when the wrapping film raw materials are mixed.
