[0026] like Figures 1-6 ;

[0027] A two-stage magnetic separation device includes a separation box 1, with a feed inlet 11 at the top of the separation box 1 through which materials are fed into the separation box 1. The separation box 1 is equipped with a magnetic separation structure 100, which is capable of two-stage magnetic separation of iron products in the materials. The magnetic separation structure 100 includes a first magnetic separation mechanism 2 and a second magnetic separation mechanism 3, which are respectively assembled inside the separation box 1. The first magnetic separation mechanism 2 is positioned above the second magnetic separation mechanism 3.

[0028] The first magnetic separation mechanism 2 includes a first electromagnetic roller 22, a first electromagnet 221, and a first adjusting plate 23. The first electromagnetic roller 22 and the first adjusting plate 23 are rotatably installed inside the separation box 1. The first electromagnets 221 are evenly embedded in the side wall of the first electromagnetic roller 22. The first electromagnetic roller 22 and the first electromagnets 221 generate magnetism when energized. When material falls onto the first electromagnetic roller 22 and the first electromagnets 221, iron products in the material can be magnetically attracted by the first electromagnetic roller 22 and the first electromagnets 221. At the same time, the first electromagnetic roller 22 and the first electromagnets 221 rotate to drive the material downward. The first adjusting plate 23 is located directly below the first electromagnetic roller 22. The first adjusting plate 23 rotates to control the falling direction of the material and iron products. A first reduction motor 27 and a second reduction motor 28 are respectively installed on the back of the separation box 1. The output end of the first reduction motor 27 is connected to the first electromagnetic roller 22 and is used to drive the first electromagnetic roller 22 to rotate. The output end of the second reduction motor 28 is connected to the first adjusting plate 23. 28 is used to drive the first adjusting plate 23 to rotate. A guide seat 21 is fixedly installed inside the separation box 1. The guide seat 21 is located on both sides of the first electromagnetic roller 22. The guide seat 21 is used to guide the material to fall, preventing the material from falling through the gaps on both sides of the first adjusting plate 23. A first guide plate 24 and a second guide plate 25 are also installed inside the separation box 1. The first guide plate 24 is used to guide the material onto the second electromagnetic roller 31, and the second guide plate 25 is used to guide the iron products into the first collecting box 26. 4. The second guide plate 25 is inclined and the lower end of the second guide plate 25 is connected to the first collection box 26 to facilitate the sliding of materials and iron products. The first collection box 26 is set on one side of the separation box 1. The first collection box 26 is used to collect iron products. An inclined plate 261 is installed inside the first collection box 26. The inclined plate 261 is used to gather the iron products in the first collection box 26 forward. The front end of the first collection box 26 is engaged with a baffle 262. Pulling the baffle 262 upward and taking it out makes it easy to take out the iron products in the first collection box 26.

[0029] Furthermore, the second magnetic separation mechanism 3 includes a second electromagnetic roller 31, a second electromagnet 32, and a second adjusting plate 33. The second electromagnetic roller 31 and the second adjusting plate 33 are rotatably installed inside the separation box 1. The second electromagnets 32 are evenly embedded in the side wall of the second electromagnetic roller 31. When the second electromagnetic roller 31 and the second electromagnets 32 are energized, they generate magnetism. When the material falls onto the second electromagnetic roller 31 and the second electromagnets 32, the iron products in the material can be attracted by the secondary magnetism of the second electromagnetic roller 31 and the second electromagnets 32. At the same time, the second electromagnetic roller 31 and the second electromagnets 32 rotate to drive the material downward. The second adjusting plate 33 is located directly below the second electromagnetic roller 31. The rotation of the second adjusting plate 33 controls the falling direction of the material and iron products, thus separating them. A third geared motor 37 and a fourth geared motor 38 are respectively installed on the back of the box 1. The output end of the third geared motor 37 is connected to the second electromagnetic roller 31, and the third geared motor 37 is used to drive the second electromagnetic roller 31 to rotate. The output end of the fourth geared motor 38 is connected to the second adjusting plate 33, and the fourth geared motor 38 is used to drive the second adjusting plate 33 to rotate. The interior of the separation box 1 is also equipped with a third guide plate 34 and a fourth guide plate 35, which are respectively inclined. A second collection box 36 is provided on the other side of the separation box 1. The third guide plate 34 is used to guide the material to fall into the second collection box 36 for collection. The fourth guide plate 35 is used to guide the iron products to fall into the first collection box 26.

[0030] The working principle of this utility model is as follows: Plastic scrap material is fed into the separation box 1 through the feed inlet 11. The first electromagnetic roller 22 and the first electromagnet 221 are energized to generate magnetism. When the material falls onto the first electromagnetic roller 22 and the first electromagnet 221, iron products in the material can be magnetically attracted by the first electromagnetic roller 22 and the first electromagnet 221. At the same time, the first geared motor 27 drives the first electromagnetic roller 22 and the first electromagnet 221 to rotate, which is used to move the material downward. The second geared motor 28 drives the first adjusting plate 23 to rotate, guiding the material to slide onto the first guide plate 24. The first guide plate 24 guides the material to fall onto the second electromagnetic roller 31. The second electromagnetic roller 31 and the second electromagnet 32 ​​are energized to generate magnetism. When the material falls onto the second electromagnetic roller 31 and the second electromagnet 32, iron products in the material can be magnetically attracted by the second electromagnetic roller 31 and the second electromagnet 32. At the same time, the third geared motor 37 drives the second electromagnetic roller 31 to rotate. The magnetic roller 31 and the second electromagnet 32 ​​rotate to move the material downwards. The fourth reduction motor 38 drives the second adjusting plate 33 to rotate, causing the material to slide onto the third guide plate 34. The material is then guided by the third guide plate 34 into the second collection box 36 for collection. The first adjusting plate 23 and the second adjusting plate 33 rotate in opposite directions. The first electromagnetic roller 22 and the first electromagnet 221 lose their magnetism and are de-energized. The iron products on the first electromagnetic roller 22 and the first electromagnet 221 slide onto the second guide plate 25 guided by the first adjusting plate 23. The iron products are then guided by the second guide plate 25 into the first collection box 26. The second electromagnetic roller 31 and the second electromagnet 32 ​​lose their magnetism and are then guided by the second adjusting plate 33 onto the fourth guide plate 35. The iron products are then guided by the fourth guide plate 35 into the first collection box 26.

[0031] In summary, by setting up a two-stage magnetic separation device, plastic debris enters the separation box 1 and undergoes two-stage magnetic separation. This not only facilitates the separation of iron products from the plastic debris, but also improves the separation effect and efficiency by using two-stage magnetic separation.
