[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1:

[0026] A circuit board recycling and crushing device, in this embodiment, as Figures 1-4 As shown, it includes a crushing box 1 and a second servo motor 14, the top inner wall of the crushing box 1 is installed with an arc-shaped enclosure 2, and the top inner wall of the arc-shaped enclosure 2 is connected to a feed hopper 3, the inner wall of the arc-shaped enclosure 2 is provided with mutually meshing crushing rollers 4, and the outer walls of the ends of the crushing rollers 4 are connected to a driving motor 5 through a coupling, the bottom of the arc-shaped enclosure 2 is provided with a crushing chamber 6, and a rotating shaft 7 is rotatably provided at the axis center of the inner wall of the crushing chamber 6, the outer wall of the rotating shaft 7 is fixed with equidistantly distributed crushing knives 8 by bolts, and one side of the rotating shaft 7 is connected to a first servo motor 9, the bottom inner wall of the crushing box 1 is fixed with a guide plate 11 in an inclined direction, and the bottom of the guide plate 11 is rotatably provided with a sorting shell 12, the bottom of the outer wall of one side of the sorting shell 12 is tightly provided with a scraper plate 15, and the lower part of the outer wall of the other side of the sorting shell 12 is provided with an inclined connecting plate 16, and the bottom outer wall of the inclined connecting plate 16 is welded with a baffle shell 17;

[0027] Firstly, the circuit board is preliminarily extruded and crushed by the intermeshing crushing rollers 4, so that the circuit board particles to be crushed can be effectively reduced in size, and the subsequent crushing effect is greatly improved. Then, the crushed particles are secondarily crushed by the continuously rotating crushing knives 8, and are screened by the arc-shaped screen plate 10, so that the screened particles are uniform in size.

[0028] The bottom inner wall of the crushing cavity 6 is provided with a discharge slot, and the inner wall of the discharge slot is fixed with the arc-shaped screen plate 10 by screws. The inner wall of the sorting shell 12 is equidistantly bonded with the magnet strips 13, and the outer wall of one side of the sorting shell 12 is connected with the second servo motor 14 at the center.

[0029] The top outer wall of the surrounding shell 17 is provided with a mounting opening, and the inner wall of the mounting opening is mounted with the air inlet fan 18.

[0030] The inner wall of the surrounding shell 17 is provided with sliding grooves 19 on both sides, and the inner wall of the sliding grooves 19 is slidingly inserted with the sliding blocks 20. The sliding blocks 20 are welded with the partition plates 21.

[0031] After the circuit board is crushed, the particles are adsorbed by the continuously rotating magnet strips 13, so that the magnetic waste can be screened and recycled. The remaining material is separated into metal particles and plastic particles by the air force of the air inlet fan 18 and the cooperation of gravity, and the size of the air force is adjusted to separate the metal particles and the plastic particles, thereby effectively improving the subsequent recycling efficiency.

[0032] In use, the crushing device is assembled first, and the external power supply is connected. Then, the circuit board to be crushed is poured into the inside of the feeding hopper 3. At this time, the two intermeshing crushing rollers 4 preliminarily extrude and crush the circuit board, so that the overall particle size of the circuit board can be effectively reduced. After crushing, the circuit board particles fall into the inside of the crushing cavity 6. At this time, the first servo motor 9 drives the crushing knives 8 to continuously rotate, so that the circuit board can be further crushed. Due to the screening treatment of the arc-shaped screen plate 10, only the particles meeting the size can fall off. The fallen particles are first attached to the outer wall of the sorting shell 12. The magnet strips 13 adsorb and fix the particles containing magnetism, and cooperate with the scraping plate 15 to scrape them out, so as to realize separation. The remaining particles containing metal and plastic roll off from the inclined connecting plate 16. At this time, the air inlet fan 18 is started, and the plastic particles and the metal particles are separated by the interaction of the air force and the gravity. The position of the partition plate 21 is adjusted, so that the plastic particles are discharged far away.
