[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-8 A crushing device for processing plastic granules includes a first crushing box 1, a feeding port 2 fixed to the top of the first crushing box 1, a second crushing box 3 fixed to the bottom of the first crushing box 1, a first U-shaped frame 4 fixed to the bottom of the second crushing box 3, a second U-shaped frame 5 fixed to the bottom of the first U-shaped frame 4, a first vertical rotating rod 8 rotatably connected to both ends inside the first crushing box 1, a plurality of first crushing blades 9 evenly distributed and fixed to the outer side of the first vertical rotating rod 8, a second vertical rotating rod 16 rotatably connected to the inside of the second crushing box 3, a third vertical rotating rod 17 rotatably connected to the inside of the second vertical rotating rod 16, a second crushing blade 10 fixed to the outer side of the top of the second vertical rotating rod 16 and the third vertical rotating rod 17, and a rotating mechanism for rotating the first vertical rotating rod 8, the second vertical rotating rod 16 and the third vertical rotating rod 17 is provided at the bottom of the second crushing box 3;

[0024] The rotating mechanism includes a first drive motor 6, a second U-shaped frame 5 with one end bolted to the first drive motor 6, a first bevel gear 13 fixed to the output end of the first drive motor 6, a second bevel gear 14 meshing with the bottom of one end of the first bevel gear 13, a third bevel gear 15 meshing with the top of one end of the first bevel gear 13, a circular rotating tube 24 fixed inside the second bevel gear 14, the circular rotating tube 24 passing through the interior of the second U-shaped frame 5 and rotatably connected to the second U-shaped frame 5 via a bearing, a third vertical rotating rod 17 passing through the interior of the circular rotating tube 24 and slidably connected to the circular rotating tube 24, a second vertical rotating rod 16 passing through the interior of the third bevel gear 15 and fixedly connected to the third bevel gear 15, and a lifting mechanism for vertically raising and lowering the third vertical rotating rod 17 is provided at the end of the second U-shaped frame 5 away from the first drive motor 6.

[0025] The rotating mechanism also includes a first gear 11, which is disposed inside the first U-shaped frame 4. A second vertical rotating rod 16 passes through the interior of the first gear 11 and is fixedly connected to the first gear 11. Both ends of the first gear 11 are meshed with second gears 12. A first vertical rotating rod 8 passes through the interior of the second gear 12 and is fixedly connected to the second gear 12. The first vertical rotating rod 8 passes through the top of the first U-shaped frame 4 and is rotatably connected to the first U-shaped frame 4 via a bearing. The first vertical rotating rod 8 passes through the interior of the first crushing box 1 and is rotatably connected to the first crushing box 1 via a bearing.

[0026] Multiple vertical sliders are fixed on the outer side of the bottom of the third vertical rotating rod 17. The inside of the circular rotating tube 24 is provided with a vertical groove that matches the vertical sliders. The third vertical rotating rod 17 and the circular rotating tube 24 are slidably connected by the cooperation of the vertical sliders and the vertical grooves. By setting the vertical sliders and the vertical grooves, the third vertical rotating rod 17 can slide vertically inside the circular rotating tube 24, thereby adjusting the distance between the top of the third vertical rotating rod 17 and the top of the second vertical rotating rod 16.

[0027] Here, the operation of the first drive motor 6 causes the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 causes the second bevel gear 14 and the third bevel gear 15 to rotate, and the rotation directions of the second bevel gear 14 and the third bevel gear 15 are opposite. The rotation of the second bevel gear 14 causes the circular rotating tube 24 to rotate, and the rotation of the circular rotating tube 24 causes the third vertical rotating rod 17 to rotate. The rotation of the third bevel gear 15 causes the second vertical rotating rod 16 to rotate, and thus the second vertical rotating rod 16 and the third vertical rotating rod 17 can rotate, and the rotation directions of the second vertical rotating rod 16 and the third vertical rotating rod 17 are opposite, so that the two second crushing blades 10 can crush the plastic particles with opposite rotation.

[0028] The rotation of the second vertical rotating rod 16 causes the first gear 11 to rotate, the rotation of the first gear 11 causes the two second gears 12 to rotate, the rotation of the two second gears 12 causes the first vertical rotating rod 8 to rotate, and in turn causes the multiple first crushing blades 9 to rotate, so that the plastic particles can be crushed by the rotation of the multiple first crushing blades 9.

[0029] The lifting mechanism includes a rectangular mounting plate 18, the top of which is fixedly connected to the first U-shaped frame 4. A second drive motor 7 is bolted to the end of the rectangular mounting plate 18 away from the second U-shaped frame 5. A rectangular rotating column 19 is fixed to the output end of the second drive motor 7. A rectangular transmission column 20 is rotatably connected to the end of the rectangular rotating column 19 near the second U-shaped frame 5. A vertical sliding column 21 is rotatably connected to the bottom of the rectangular transmission column 20 through a pin. A rectangular limiting block 22 is slidably connected to the outside of the vertical sliding column 21. The rectangular limiting block 22 is fixedly connected to the end of the second U-shaped frame 5 near the second U-shaped frame 5. A horizontal connecting plate 23 is fixed to the bottom of the vertical sliding column 21. The bottom of the third vertical rotating rod 17 is rotatably connected to the top of the horizontal connecting plate 23 through a bearing.

[0030] The rectangular limiting block 22 has a rectangular through groove inside. The vertical sliding column 21 is located inside the rectangular through groove and is slidably connected to the rectangular limiting block 22 through the rectangular through groove. The rectangular through groove allows the vertical sliding column 21 to slide vertically inside the rectangular limiting block 22, thereby guiding the vertical lifting trajectory of the vertical sliding column 21.

[0031] Here, the operation of the second drive motor 7 enables the rectangular rotating column 19 to rotate. The rotation of the rectangular rotating column 19, through the rectangular transmission column 20, enables the vertical sliding column 21 to slide vertically inside the rectangular limiting block 22. The vertical sliding of the vertical sliding column 21, through the transverse connecting plate 23, enables the third vertical rotating rod 17 to slide vertically inside the circular rotating tube 24, thereby enabling the third vertical rotating rod 17 to slide vertically inside the second vertical rotating rod 16. This allows the distance between the top of the third vertical rotating rod 17 and the top of the second vertical rotating rod 16 to be adjusted, and thus the distance between the two second crushing blades 10 can be adjusted.

[0032] The device is equipped with two synchronously rotating first vertical rotating rods 8, which enable multiple first crushing blades 9 to rotate and simultaneously shear the material multiple times, significantly improving crushing efficiency. It is especially suitable for processing high-hardness or high-toughness plastics. Two counter-rotating second crushing blades 10 can effectively solve the problem of material residue at the bottom of traditional devices, ensuring that the material is fully crushed and further improving the overall crushing efficiency. The distance between the two second crushing blades 10 can be adjusted according to the material characteristics, ensuring that different types or sizes of plastic materials can be crushed uniformly, avoiding the problem of inconsistent particle size. The rotation of the first crushing blades 9 and the second crushing blades 10 allows the material to undergo multiple shearing processes during crushing, resulting in more uniform crushed particles that meet the quality requirements of subsequent processing.

[0033] Working principle: The operation of the first drive motor 6 causes the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 causes the second bevel gear 14 and the third bevel gear 15 to rotate, and the rotation directions of the second bevel gear 14 and the third bevel gear 15 are opposite. The rotation of the second bevel gear 14 causes the circular rotating tube 24 to rotate, and the rotation of the circular rotating tube 24 causes the third vertical rotating rod 17 to rotate. The rotation of the third bevel gear 15 causes the second vertical rotating rod 16 to rotate, and thus the second vertical rotating rod 16 and the third vertical rotating rod 17 can rotate, and the rotation directions of the second vertical rotating rod 16 and the third vertical rotating rod 17 are opposite. This allows the two second crushing blades 10 to crush the plastic particles with opposite rotation.

[0034] The rotation of the second vertical rotating rod 16 causes the first gear 11 to rotate, the rotation of the first gear 11 causes the two second gears 12 to rotate, the rotation of the two second gears 12 causes the first vertical rotating rod 8 to rotate, and in turn causes the multiple first crushing blades 9 to rotate, so that the plastic particles can be crushed by the rotation of the multiple first crushing blades 9.

[0035] The operation of the second drive motor 7 enables the rectangular rotating column 19 to rotate. The rotation of the rectangular rotating column 19, through the rectangular transmission column 20, enables the vertical sliding column 21 to slide vertically inside the rectangular limiting block 22. The vertical sliding of the vertical sliding column 21, through the horizontal connecting plate 23, enables the third vertical rotating rod 17 to slide vertically inside the circular rotating tube 24, thereby enabling the third vertical rotating rod 17 to slide vertically inside the second vertical rotating rod 16. This allows the distance between the top of the third vertical rotating rod 17 and the top of the second vertical rotating rod 16 to be adjusted, and thus the distance between the two second crushing blades 10 can be adjusted.
