Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0034] Combine Figure 1-2The utility model is a mixing device for the production of polystyrene particles, including a mixing tank 1, a fixed frame 4 is fixedly connected to the top of the mixing tank 1, a motor 7 is fixedly connected to the bottom of the fixed frame 4, the starting motor 7 can drive the driving shaft 8 to rotate, the output end of the motor 7 is fixedly connected to the driving shaft 8, the driving shaft 8 is rotatably connected to the mixing tank 1, the driving shaft 8 passes through the mixing tank 1 and extends into the interior of the mixing tank 1, the outer wall of the driving shaft 8 is fixedly connected to a fixed block 18, the outer wall of the fixed block 18 is fixedly connected to a uniformly distributed stirring rack 19, because the driving shaft 8 is in a rotating state, it will drive the multiple stirring racks 19 on the fixed block 18 to rotate synchronously, and the stirring rack 19 is fixed on one side close to the driving shaft 8. It is fixedly connected with a stirring blade 20, and the stirring blade 20 on the stirring frame 19 will also be driven to continuously stir and mix the raw materials inside the mixing tank 1. The outer wall of the driving shaft 8 is fixedly connected with an auger 23, and the auger 23 is located below the fixed block 18. The auger 23 on the driving shaft 8 will also rotate. The inner wall of the mixing tank 1 is fixedly connected with evenly distributed fixed columns 22, and the end of the fixed column 22 away from the mixing tank 1 is fixedly connected with a separating cylinder 21. The separating cylinder 21 and the auger 23 are rotatably connected. Because the outer sleeve of the auger 23 is provided with a separating cylinder 21, a separating effect is formed. Therefore, the auger 23 will drive the raw material spiral at the bottom of the mixing tank 1 upward to the top, thereby accelerating the mixing process.

[0035] Combine Figure 4-5 , a raw material chopping assembly is provided on the outside of the mixing tank 1, and the raw material chopping assembly includes a driving bevel gear 9, which is fixedly connected to the outer wall of the driving shaft 8. The driving bevel gear 9 is located above the mixing tank 1, and the top of the mixing tank 1 is fixedly connected to a fixing frame 11. The internal rotation of the fixing frame 11 is connected to a driven shaft 12, and the end of the driven shaft 12 close to the driving shaft 8 is fixedly connected to a driven bevel gear 10. The driven bevel gear 10 is meshed with the driving bevel gear 9. The driving shaft 8 is provided with a driving bevel gear 9, and the top of the mixing tank 1 is provided with a driven shaft 12 fixed by a fixing frame 11, and one end of the driven shaft 12 is provided with a driven bevel gear 10. The driving bevel gear 9 and the driven bevel gear 9 are connected. The moving bevel gears 10 are meshed with each other, so the rotation of the driving shaft 8 will drive the driven shaft 12 to rotate synchronously. The other end of the driven shaft 12 is rotatably connected to the shell 13. The driven shaft 12 passes through the shell 13 and extends into the interior of the shell 13. The bottom of the shell 13 is fixedly connected to the support seat 3. The outer wall of the driven shaft 12 is fixedly connected to the screening drum 14. The driven shaft 12 passes through the screening drum 14 and extends into the interior of the screening drum 14. The screening drum 14 is rotatably connected to the interior of the shell 13. The rotation of the driving shaft 8 will drive the driven shaft 12 to rotate synchronously. The other end of the driven shaft 12 is provided with a screening drum 14, which accordingly causes the screening drum 14 to rotate synchronously inside the shell 13.

[0036] Combine Figure 4-5, a feeding pipe 5 is fixedly connected to the side of the shell 13 away from the mixing tank 1, and the feeding pipe 5 passes through the shell 13 and extends into the interior of the shell 13, and the raw materials enter the shell 13 through the feeding pipe 5, and the inner wall of the screening drum 14 is fixedly connected with evenly distributed guide plates 16, and spiral blades 15 are arranged between the evenly distributed guide plates 16. When the guide plates 16 rotate with the screening drum 14, the raw materials accumulated on the side of the guide plates 16 will be driven upward by the guide plates 16. When the guide plates 16 rotate to a higher position, the guide plates 16 are tilted, and the raw materials above will slide along the tilted guide plates 16 toward the spiral blades 15, thereby improving the chopping efficiency, and the spiral blades 15 are fixedly connected to the outer wall of the driven shaft 12 and enter the shell 13 through the feeding pipe 5. After the raw materials are sorted, they will stagnate inside the screening drum 14 inside the shell 13. Because the inside of the screening drum 14 is provided with a spiral blade 15 that rotates synchronously with the driven shaft 12, it can cut larger pieces of raw materials. The bottom of the shell 13 is fixedly connected with a connecting pipe 17, and one end of the connecting pipe 17 is fixedly connected to the mixing tank 1. The two ends of the connecting pipe 17 respectively pass through the mixing tank 1 and the shell 13, and extend into the interior of the mixing tank 1 and the shell 13 respectively. Raw materials smaller than the mesh holes on the screening drum 14 will fall into the inside of the screening drum 14 and enter the interior of the mixing tank 1 through the connecting pipe 17 to start raw material mixing. The bottom of the mixing tank 1 is fixedly connected with evenly distributed supporting legs 2, and the bottom of the mixing tank 1 is fixedly connected with a discharge pipe 6. The discharge pipe 6 passes through the mixing tank 1 and extends to the interior of the mixing tank 1.

[0037] Working principle: Before using this device, the user should first check this device and confirm that the device is intact without any damage. Then, the motor 7 is started to drive the driving shaft 8 and the driving bevel gear 9 to rotate synchronously, which in turn drives the driven bevel gear 10 and the driven shaft 12 to rotate synchronously. At the same time, the driven shaft 12 will also drive the screening drum 14 to rotate inside the outer shell 13. At this time, the user feeds raw materials into the inner shell 13 through the feeding pipe 5. After the raw materials pass through the feeding pipe 5 and enter the inner shell 13, they will stagnate inside the screening drum 14 inside the outer shell 13. Because there is a spiral blade 15 inside the screening drum 14 that rotates synchronously with the driven shaft 12, larger pieces of raw materials can be chopped. At this time, raw materials smaller than the mesh holes of the screening drum 14 will fall into the inner screen drum 14 and enter the inner part of the mixing tank 1 through the connecting pipe 17 to start raw material mixing. Raw materials larger than the mesh holes of the screening drum 14 will continue to be chopped inside the screening drum 14. At the same time, because a plurality of guide plates 16 are provided inside the screening drum 14, when the guide plates 16 rotate with the screening drum 14, the raw materials accumulated on the side of the guide plates 16 will be driven upward by the guide plates 16. When the guide plates 16 rotate to a higher position, the guide plates 16 are inclined, and the raw materials above will slide along the inclined guide plates 16 toward the spiral blades 15, thereby improving the chopping efficiency. At the same time, the interior of the mixing tank 1 is also mixing the raw materials. Because the driving shaft 8 is in a rotating state, it will drive the multiple stirring frames 19 on the fixed block 18 to rotate synchronously. At the same time, the stirring blades 20 on the stirring frame 19 will also be driven to continuously stir and mix the raw materials inside the mixing tank 1. The auger 23 on the driving shaft 8 will also rotate, but because the outer sleeve of the auger 23 is provided with a separation cylinder 21, it forms a separation effect. Therefore, the auger 23 will drive the raw material spiral at the bottom of the mixing tank 1 upward to the top, thereby accelerating the mixing process.
