[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4A polypropylene mixing device with uniform mixing includes a mounting base 1, a discharging pipe is fixedly arranged at the bottom of the mounting base 1, and a control valve is fixedly arranged on the discharging pipe. The discharging pipe is arranged to facilitate the uniform mixing of polypropylene and mixed materials from a mixing box 3, and the opening and closing of the discharging pipe is conveniently controlled by the arrangement of the control valve. A supporting vertical plate 2 is fixedly arranged on the top of the mounting base 1, a mixing box 3 is fixedly arranged on the top of the supporting vertical plate 2, a stirring motor 4 is fixedly arranged at the bottom of the mixing box 3, a rotating shaft 5 is fixedly arranged at the output end of the stirring motor 4, a stirring paddle 23 is fixedly arranged on the surface of the rotating shaft 5, the number of the stirring paddles 23 is all several, the several stirring paddles 23 are all located inside the mounting base 1 and are distributed in a linear array, and the several stirring paddles 23 are arranged on the surface of the rotating shaft 5. The arrangement of the stirring paddle 23 enables the stirring paddle 23 to stir the polypropylene and the mixed material at different positions, thereby reducing the mixing time of the polypropylene and the mixed material. A material discharge assembly is arranged on the top of the rotating shaft 5 for facilitating the breaking up of the material, and the material discharge assembly comprises a supporting circular plate 6, the supporting circular plate 6 is fixedly mounted on the top of the rotating shaft 5, a mounting column 7 is fixedly arranged on the top of the supporting circular plate 6, a limiting convex plate 8 is fixedly arranged on the surface of the mounting column 7, a fixing stud 9 is fixedly arranged on the top of the mounting column 7, a rotating disk 10 is overlapped on the top of the supporting circular plate 6, the number of the limiting convex plates 8 and the limiting grooves 12 are both four, and the four limiting convex plates 8 and the four limiting grooves 12 are all distributed in a circular array, the limiting convex plates 8 are made of metal material, and the four limiting convex plates 8 and the four limiting grooves 12 are arranged in a circular array. The setting of the limiting groove 12 makes it more stable for the mounting column 7 to drive the rotating disk 10 to rotate, so that after a connection between a limiting convex plate 8 and the mounting column 7 is broken, the mounting column 7 can still drive the rotating disk 10 to rotate, so that the rotating disk 10 can normally scatter the materials. A mounting hole 11 is provided through the top of the rotating disk 10, and the mounting hole 11 is overlapped with the mounting column 7. A limiting groove 12 is provided inside the mounting hole 11, and the limiting groove 12 is overlapped with the limiting convex plate 8. A limiting circular plate 13 is overlapped on the surface of the fixing stud 9, and a fixing nut 14 is threadedly provided on the surface of the fixing stud 9. Through the setting of the unloading component, it is convenient to scatter the polypropylene and the mixed material entering the mixing box 3 and throw them around the mixing box 3, so as to facilitate the dispersion of the materials in the mixing box. In the box 3, the fixing nut 14 and the limiting circular plate 13 are removed from the fixing stud 9, and the rotating disk 10 is pulled to move upward, so that the mounting column 7 and the limiting convex plate 8 are removed from the mounting hole 11 and the limiting groove 12, so as to facilitate the replacement of the damaged rotating disk 10. A box cover 15 is fixedly arranged on the top of the mounting base plate 1, and a storage component for storing materials is arranged on the top of the box cover 15. A blocking component for blocking the storage component is arranged inside the mounting base plate 1. The rotating shaft 5 is driven to rotate by the stirring motor 4, and the rotating shaft 5 drives the stirring paddle 23 and the supporting circular plate 6 to rotate. The supporting circular plate 6 drives the rotating disk 10 to rotate through the mounting column 7 and the limiting convex plate 8, so that the entering polypropylene and mixed materials are scattered by the rotating disk 10 and thrown to the surroundings of the mixing box 3.The polypropylene and the mixed material are dispersed in the mixing box 3, and the dispersed polypropylene and the mixed material are stirred and mixed again by the stirring paddle 23, thereby avoiding the situation that the mixing device can only feed materials in the same area, resulting in a long time of stirring before mixing, and avoiding the situation that the time used for uniform mixing increases and affects the preparation of polypropylene.

[0021] Specifically, the storage component includes a feed pipe 16, which is fixedly installed inside the box cover 15, a storage box 17 is fixedly arranged on the top of the feed pipe 16, and a partition plate 18 is fixedly arranged inside the storage box 17.

The rotating shaft 19 is driven to rotate by the hand-held knob 20, so that the connecting plate 21 drives the blocking plate 22 to be located at the bottom of the feed pipe 16, and then the polypropylene and the mixed material are put into the storage box 17, and the polypropylene and the mixed material are separated and placed by the partition plate 18. When the polypropylene and the mixed material need to be put into the mixing box 3, the hand-held knob 20 drives the connecting plate 21 to move through the rotating shaft 19, so that the blocking plate 22 is removed from the feed pipe 16, thereby facilitating the polypropylene and the mixed material to enter the mixing box 3 through the feed pipe 16.

[0022] The polypropylene mixing device with uniform mixing is connected to a 220V mains power supply, and the main controller can be a conventional known device for control such as a computer.

[0023] When in use: put polypropylene and mixed material into the material storage box 17, and separate the polypropylene and mixed material by the partition plate 18, drive the output end of the stirring motor 4 to drive the rotating shaft 5 to rotate, drive the stirring paddle 23 to rotate by the rotating shaft 5, and drive the supporting circular plate 6 to rotate by the rotating shaft 5, so that the supporting circular plate 6 drives the limiting convex plate 8 and the fixing stud 9 to rotate through the mounting column 7, and under the action of the limiting convex plate 8 and the limiting groove 12, the mounting column 7 drives the rotating disk 10 to rotate, and then the hand-held knob 20 is turned to drive the rotating shaft 19 to rotate, so that the rotating shaft 19 drives the connecting The plate 21 moves, and the sealing plate 22 is driven to move away from the bottom of the feed pipe 16 through the connecting plate 21. At this time, the polypropylene and the mixed material in the storage box 17 enter the mixing box 3 through the feed pipe 16. The polypropylene and the mixed material entering the mixing box 3 contact the rotating disk 10. The rotating rotating disk 10 breaks up the polypropylene and the mixed material falling on its surface, and throws the polypropylene and the mixed material to the surroundings, so that the polypropylene and the mixed material are dispersed in the mixing box 3, and the entering polypropylene and the mixed material are stirred by the stirring paddle 23, so that the polypropylene and the mixed material are evenly mixed.

[0024] In summary, the polypropylene mixing device with uniform mixing drives the rotating shaft 5 to rotate through the stirring motor 4, and the rotating shaft 5 drives the stirring paddle 23 and the supporting circular plate 6 to rotate, and the supporting circular plate 6 drives the rotating disk 10 to rotate through the mounting column 7 and the limiting convex plate 8, so that the incoming polypropylene and the mixed material are broken up by the rotating disk 10 and thrown to the surroundings of the mixing box 3, so that the polypropylene and the mixed material are dispersed inside the mixing box 3, and then the dispersed polypropylene and the mixed material are stirred and mixed again by the stirring paddle 23, thereby avoiding the situation that the mixing device can only feed in the same area, resulting in a long time of stirring for mixing, and avoiding the situation that the time used for uniform mixing increases and affects the preparation of polypropylene, and is used to solve the problems raised in the above-mentioned background technology.
