Threaded rods 9 and sliding rods are installed above the plate 10 and inside the processing box 1, and a moving seat 21 is connected between the threaded rod 9 and the sliding rod. One end of the threaded rod 9 passes through one side of the processing box 1 and is connected to the driving motor 8. A rolling roller 17 is mounted at the bottom of the moving seat 21, and a plurality of groups of crushing thorns 19 are installed around the surface of the rolling roller 17. A plurality of groups of counterweight cavities 18 are evenly opened inside the rolling roller 17, and a counterweight rod 20 is inserted inside the counterweight cavity 18. The purpose of setting the counterweight rod 20 is to change the degree of extrusion and crushing of the circuit board by adjusting the counterweight, so as to better meet the crushing requirements.

[0032] In one embodiment, several groups of second rotating structures 16 are staggeredly installed below the screening plate 10, one end of the second rotating structure 16 is connected to a guide plate 11, and several groups of electromagnets 12 are evenly installed on the surface of the guide plate 11. A collecting box 14 is installed below the guide plate 11 at the bottom end of the processing box 1, and a collecting cavity 15 is symmetrically opened inside the collecting box 14. The electromagnet 12 is provided to realize the adsorption operation of the magnetic material in the circuit board to facilitate subsequent recycling.

[0033] In one embodiment, the first rotating structure and the second rotating structure 16 are both composed of a motor and a rotating shaft.

[0034] In one embodiment, a feed port 2 is installed in the middle of the top surface of the processing box 1. The provision of the feed port 2 facilitates the entry and use of waste circuit boards that need to be processed, and facilitates subsequent processing.

[0035] In one embodiment, a base 13 is fixedly installed on the bottom surface of the processing box 1, and the entire device can be fixed by the base 13, so as to enhance the overall stability in use.

[0036] In one embodiment, the crushing spikes 19 are increasingly sharp and have an increasing density. The structural changes of the crushing spikes 19 are intended to achieve a more detailed crushing operation on the circuit board.

[0037] In one embodiment, the rotation dimension of the guide plate 11 is smaller than the internal dimension of the processing box 1 , and the rotation dimension is set to ensure that the guide plate 11 can be smoothly rotated and adjusted inside the processing box 1 .

[0038] In one embodiment, the size of the holes on the surface of the screening plate 10 gradually decreases, and the change in the holes is to achieve a more detailed classification operation of the crushed circuit boards.

[0039] Working principle: In actual use, personnel can add the waste circuit boards that need to be crushed and sorted into the device through the feed port 2. At this time, the fallen circuit boards fall back to the surface of the carrying plate 4. At this time, the push plates 5 can be driven to approach each other through the ejection of the hydraulic rods 22 on both sides. At this time, the crushing cones 3 on the surface of the push plates 5 will be interlaced and inserted with each other. At this time, the larger blocks of circuit boards can be stabbed and crushed. Then, after the preliminary crushing is completed, the baffle 7 can be turned down by the rotation of the first rotating structure 6. At this time, the circuit boards will fall naturally due to gravity. The fallen circuit boards will fall on the topmost screening plate 10, and then fall on the screening plates 10 at different positions in turn. After the circuit boards fall on the screening plate 10, the operation of the drive motor 8 can drive the threaded rod 9 to rotate back and forth, thereby driving the moving seat 21 to move back and forth. At this time, the rolling roller 17 at the bottom of the moving seat 21 will roll the circuit boards on the surface. Since the surface of the rolling roller 17 is provided with crushing thorns 19, the circuit board can be crushed very well. Since the shape of the crushing thorns 19 is becoming more and more sharp and the density is becoming larger and larger, the circuit board can be crushed more densely step by step, thereby improving the overall crushing effect. After passing through the lowest screening plate 10, the circuit board will continue to fall and be diverted to the corresponding collecting chamber 15 through the guide plate 11. The guide plate 11 is provided with an electromagnet 12 to adsorb the magnetic material in the circuit board. After a certain amount is adsorbed, the direction of the guide plate 11 can be flipped through the second rotating structure 16 so that it points to the inside of the collecting chamber 15 on the other side. At this time, the magnetic material can be collected by releasing the electromagnet 12, thereby reducing the subsequent manual classification operation, improving the overall operation efficiency, and reducing the labor intensity of personnel. The device as a whole has the advantages of good crushing effect, multi-stage crushing, and classified collection.
