[0025] In this embodiment, the first servo motor 38 is used to drive the vertical rod 34, and the second servo motor 39 is used to drive the threaded rod 310. When the transmission rod 31 drives the partition plate 32, the second servo motor 39 can synchronously drive the threaded rod 310. The movable plate 37 is threadedly connected to the threaded rod 310 through the hollow threaded cylinder 317. During the rotation of the threaded rod 310, the height of the movable plate 37 will be changed by the hollow threaded cylinder 317. There are three movable plates 37, one of which is set on the threaded rod 310, and the other two movable plates 37 are sleeved on the thin rod 312. The connecting block 35 is installed at the end of the movable plate 37. The height of the movable plate 37 can be changed to adjust the height of the stirring blade 36.

[0028] How to use and working principle of this device: First, open the sealing cover 7 and pour the raw materials of the plastic products into the mixing box 1. At this time, it is necessary to ensure that the electric telescopic rod 8 pushes the blocking plate 9 to the bottom of the mixing box 1. After pouring the raw materials, cover the sealing cover 7; The mixing assembly 3 is started to stir the raw materials of the plastic product. The reduction motor in the hollow box 5 drives the transmission rod 31 through the belt transmission assembly 6. The transmission rod 31 drives the partition plate 32 during rotation. The vertical rod 34 drives the connecting block 35. The stirring blades 36 on the connecting block 35 are used to mix the raw materials together. During the mixing process, the second servo motor 39 drives the threaded rod 310. When the threaded rod 310 rotates, the movable plate 37 is lifted. The movable plate 37 drives the connecting block 35 to adjust the height of the stirring blade 36 so that the stirring blade 36 contacts the raw materials at different heights. There are three movable plates 37, one of which is set on the threaded rod 310, and the other two movable plates 37 are sleeved on the thin rod 312. The three movable plates 37 are connected together by the first single-head rotating rod 314, the double-head rotating rod 315 and the second single-head rotating rod 316. When the uppermost movable plate 37 starts to move, it will synchronously drive the lower movable plate 37, and the displacement of the lower movable plate 37 is smaller than the displacement of the upper movable plate 37, so as to ensure that the two movable plates 37 can be pulled out to a sufficient distance to allow the stirring blade 36 to rotate in the vertical direction. After adjusting the height of the stirring blade 36, the first servo motor 38 drives the vertical rod 34, and the limiting convex strip 311 on the outer wall of the vertical rod 34 drives the worm gear 321 through the worm 319. The worm gear 321 drives the stirring blade 36 during rotation. After mixing with the raw materials, the electric telescopic rod 8 drives the sealing plate 9 to move downward, so that the raw materials fall into the charging box 2, thereby completing the mixing and collection of the raw materials.
