Each set of screening components includes a screening trough 3, a guide pipe 4, a screening screen 5, and a pull rod 6. A feed port 7 is provided at the top side of the mixing box 1. The guide pipe 4 is connected to the mixing box 1 and communicates with the feed port 7. The bottom end of the screening trough 3 is connected to the top end of the guide pipe 4. An annular groove 8 is provided on the inner side wall of the screening trough 3. The screening screen 5 is located in the annular groove 8 and its front and rear ends are slidably connected to the front and rear ends of the annular groove 8, respectively. A sliding hole is provided on the side of the annular groove 8 away from the mixing box 1. The pull rod 6 is slidably connected to the sliding hole and one side of the pull rod 6 is connected to the screening screen 5.

[0024] A drive assembly is installed on one side of the screening tank 3. The drive assembly drives the pull rod 6 to reciprocate. PET foam granules are poured into the screening tank 3. By rapidly pulling the pull rod 6, the screening screen 5 can be driven to slide rapidly back and forth in the annular groove 8. The screening screen 5 is always located within the annular groove 8, which prevents PET foam granules from entering the annular groove 8 during screening, reducing the possibility of the screening screen 5 getting stuck. The rapid reciprocating movement of the screening screen 5 can screen the PET foam granules in the screening tank 3. The screened granules enter the mixing box 1 through the guide pipe 4 and the feed port 7. Therefore, a PET foam granule mixing device is provided, which can process large impurities or clumps of foam granules mixed in with the PET foam granules poured into the mixing device, thereby improving the mixing effect when mixed with other material additives.

The first connecting shaft 13 is connected to the other side of the turntable 12 and is located away from the center of the turntable 12. One end of the connecting plate 14 is rotatably connected to the first connecting shaft 13, and the other end of the connecting plate 14 is rotatably connected to the second connecting shaft 15. The second connecting shaft 15 is connected to the other side of the pull rod 6. When the first motor 10 is powered on and started, the first motor 10 drives the drive shaft 11 and the turntable 12 to rotate, while simultaneously driving the first connecting shaft 13 to perform circular motion. At the same time, the connecting plate 14 and the pull rod 6 are moved in reciprocating motion to realize the drive process.

[0026] Please see Figures 1-5 It also includes a second motor 16 and a stirring shaft 17. The second motor 16 is connected to the top of the mixing box 1.

The stirring shaft 17 is provided with a spiral stirring blade 18. When the second motor 16 is powered on and started, the second motor 16 drives the stirring shaft 17 and the spiral stirring blade 18 to rotate, and the PET foam particles in the mixing box 1 are mixed and stirred by the spiral stirring blade 18.

[0027] Please see Figures 1-5 The top of the screening tank 3 is equipped with a cover 19; the cover 19 can reduce the possibility of dust being emitted and polluting the air during screening.

By rapidly pulling the lever 6 back and forth, the screening screen 5 can be driven to slide back and forth quickly within the annular groove 8. The screening screen 5 is always located within the annular groove 8, which prevents PET foam granules from entering the annular groove 8 during screening, reducing the possibility of the screening screen 5 getting stuck. The rapid back and forth movement of the screening screen 5 can screen the PET foam granules located in the screening tank 3. The screened granules enter the mixing box 1 through the guide pipe 4 and the feed inlet 7.

[0030] The first motor 10 and the second motor 16 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, so we will not go into detail here.
