DETAILED DESCRIPTION

[0024] Example 1

[0025] like Figures 1-6As shown, the present embodiment proposes a waste recycling device for producing plastic particles, which includes a frame 1, a lower hopper 2, a plastic separation box 3, a rotating part 4 and an electromagnet adsorption mechanism.

[0026] The plastic separation tank 3 is mounted on the frame 1 and comprises an integrally connected feed tube 31, a separation tank 32, a screening tank 33, an iron collection tank 34, and a discharge tube 35. The feed tube 31, separation tank 32, screening tank 33, and discharge tube 35 are interconnected from top to bottom. The lower hopper 2 is connected to the top of the feed tube 31. Crushed waste plastic is added to the lower hopper 2, which then passes through the feed tube 31 and into the separation tank 32.

[0027] The iron collecting box portion 34 is connected to the separation box portion 32 and is located on a lateral side of the screening box portion 33. The outer bottom end of the iron collecting box portion 34 is rotatably connected to a box door 341, and a door lock is installed on the box door 341.

[0028] The rotating member 4 is rotatably arranged on the separation box portion 32, with a cavity on the inside and a plurality of adsorption grooves evenly distributed around the central axis on the outside. The adsorption grooves are U-shaped open structures, and the side walls of the adsorption grooves are used to adsorb iron materials through an electromagnet adsorption mechanism.

[0029] The electromagnet adsorption mechanism creates a magnetic attraction force in the cavity. When the rotating member 4 rotates counterclockwise, in the process of the adsorption trough rotating from the feed barrel 31 to the screening box 33, the electromagnet adsorption mechanism adsorbs the iron in the material into the adsorption trough through the rotating member 4. The plastic in the material moves with the rotating member 4. When the adsorption trough rotates to connect with the screening box 33, the plastic in the material falls into the screening box 33 and is eventually discharged downward from the discharge barrel 35. When the adsorption trough rotates from connecting with the screening box 33 to connecting with the iron collection box 34 and the separation box 32, that is, when the adsorption trough rotates to connect with the iron collection box 34, the magnetic attraction force in the adsorption trough area is lost, and the iron in the adsorption trough falls into the iron collection box 34 due to its own gravity. The iron is collected by the iron collection box 34. When the iron needs to be cleaned, the door lock is opened, the box door 341 is opened, and the iron in the iron collection box 34 is cleaned out.

[0030] The separation box portion 32 is a circular hollow structure, leaving an area connected to the feed cylinder portion 31, the screening box portion 33 and the iron collection box portion 34. The outer peripheral surface of the rotating member 4 contacts the inner peripheral surface of the separation box portion 32. When the rotating member 4 rotates and transports the material received from the feed cylinder portion 31, the material is received in the inner side of the adsorption tank, and the separation box portion 32 limits the material. A connecting cylinder portion 13 is coaxially provided at one axial end of the rotating member 4, and a fixed cylinder 10 is provided on the separation box portion 32. The connecting cylinder portion 13 is coaxially rotatably provided on the fixed cylinder 10, and the connecting cylinder portion 13 is rotatably connected to the separation box portion 32. The position of the fixed cylinder 10 remains unchanged, and the connecting cylinder portion 13 can rotate, and when rotating, it can drive the rotating member 4 to rotate.

[0031] The electromagnet adsorption mechanism includes a main station 9 coaxially arranged on the fixed cylinder 10 and multiple groups of magnetic attraction components evenly distributed around the fixed cylinder 10. The main station 9 is externally connected to the wire passing through the fixed cylinder 10, and the wire is connected to the external power supply. Figure 2 As shown, the cavity of the rotating member 4 includes a central cavity and branch cavities evenly distributed around the central cavity and all connected to the central cavity, and each branch cavity corresponds to a group of magnetic attraction components.

[0032] The outer circumference of the main station 9 has a groove 901 and forms an arc-shaped contact surface 91. The groove 901 faces the connection between the iron collecting box part 34 and the separation box part 32. The magnetic attraction component includes a sub-conductor 8, a cable 7, an iron core coil winding 6 and an iron absorption plate 5, which are conductively connected in sequence. The sub-conductor 8 is set on the inner wall of the central cavity and intermittently slides in contact with the contact surface 91. The iron absorption plate 5 includes a connecting plate portion and a bonding plate portion made of iron that are integrally connected. The bonding plate portion is bonded to the inner wall of the branch cavity. The magnetic attraction component rotates with the rotating part 4, and the main station 9 and the fixed cylinder 10 are stationary. When the sub-conductor 8 in the magnetic attraction component contacts the main station 9, the sub-conductor 8 conducts electricity, and the magnetic attraction component is energized, generating a magnetic attraction force on the iron absorption plate 5. The magnetic attraction force of the iron absorption plate 5 can act on the iron material in the material in the adsorption tank through the rotating part 4, and the iron material is adsorbed on the side wall of the adsorption tank. When the sub-conductor stage 8 rotates toward the groove 901, it disengages from the main stage 9, the magnetic attraction of the magnetic plate 5 disappears, and the iron material on the sidewalls of the adsorption groove falls due to gravity. The rotating member 4 is made of a rigid insulating material such as hard plastic or stainless steel. The multiple adsorption grooves on the rotating member 4 sequentially receive material falling from the feed barrel 31. Each time, a limited amount of material is received, ensuring effective adsorption of the iron material in the material.

[0033] This embodiment can separate out the doped iron material, thereby ensuring the quality of plastic separation and recycling. When the material falls from the lower hopper 2 through the feed cylinder 31, it will enter the adsorption trough that rotates to an upward distribution. The rotating part 4 drives the material in the adsorption trough counterclockwise. During this process, the electromagnet adsorption mechanism uses the magnetic plate 5 to adsorb the iron material in the material on the side wall of the adsorption trough. When the adsorption trough rotates toward the screening box part 33, the plastic in the material falls due to gravity. As the rotating part 4 continues to rotate, when the magnetic plate 5 corresponding to the adsorption trough loses its magnetic attraction, the adsorbed iron material will fall into the iron collecting box part 34 under the action of its own gravity, thereby realizing the separation of plastic and iron material.

[0034] Example 2

[0035] like Figures 1-6As shown, this embodiment proposes a waste recycling device for plastic pellet production. Compared to the first embodiment, the screening box portion 33 in this embodiment is a circular hollow structure, leaving an area for communication with the separation box portion 32. A second rotating shaft 19 is rotatably mounted on the screening box portion 33. A swing frame 20 is mounted on the second rotating shaft 19, and the swing frame 20 has dropout holes 201 evenly distributed therein. Plastic that falls from the adsorption trough of the rotating member 4 continues to fall through the dropout holes 201 and is ultimately discharged downward from the discharge barrel 35.

[0036] The plastic separation box 3 is provided with a mounting cover 11, on which is provided a power device 12 drivingly connected to the connecting cylinder 13. The power device 12 is used to drive the connecting cylinder 13 to rotate. A driving gear 14 is coaxially provided on the connecting cylinder 13. A first rotating shaft 151 is rotatably provided on the plastic separation box 3. The first rotating shaft 151 is provided with a rotating disk 16 and a driven gear 15 meshing with the driving gear 14. The driven gear 15 is smaller than the driving gear 14. The rotating disk 16 is eccentrically connected to a first connecting rod 17. The end of the first connecting rod 17 is rotatably connected to a second connecting rod 18. The end of the second connecting rod 18 is provided on a second rotating shaft 19.

[0037] In this embodiment, the power device 12 drives the connecting cylinder 13 to rotate, and the connecting cylinder 13 drives the rotating member 4 to rotate counterclockwise. The rotating member 4 receives the material from the feed cylinder 31 and conveys the material downward. The connecting cylinder 13 also drives the driven gear 15 to rotate through the driving gear 14. The driven gear 15 drives the turntable 16 to rotate through the first rotating shaft 151. The turntable 16, the first connecting rod 17, the second connecting rod 18, and the second rotating shaft 19 form a crank rocker mechanism, which can realize the reciprocating swing of the second rotating shaft 19. The second rotating shaft 19 drives the swing frame 20 to swing back and forth. The swing frame 20 lifts the material falling from the adsorption trough back and forth by swinging. When the iron material in the material moves upward, it can re-enter the inner side of the adsorption trough and be adsorbed by the iron absorption plate 5 on the side wall of the adsorption trough, thereby further increasing the adsorption capacity of the iron material. Multiple adsorption troughs collect materials in turn, and the material transfer volume is limited. It can also prevent too much material from falling onto the swing frame 20, avoiding the situation where the swing frame 20 cannot effectively lift the material, and also avoiding the situation where there is too much material, causing the iron material to be difficult to be adsorbed when it is lifted upward.

[0038] Example 3

[0039] like Figures 1-6As shown, this embodiment proposes a waste recycling device for plastic pellet production. Compared with the first embodiment, this embodiment further includes a screening adjustment component. The screening adjustment component includes a motor 22 arranged at the bottom of the swing frame 20, a screw rod 23 connected to the output end of the motor 22, an adjustment frame 21 threadedly connected to the screw rod 23, and a guide rod 24 arranged at the bottom of the swing frame 20 and slidably connected to the adjustment frame 21. The motor 22 can drive the screw rod 23 to rotate forward and reverse, and the screw rod 23 drives the adjustment frame 21 to move. The guide rod 24 is parallel to the screw rod 23 and can guide the adjustment frame 21 so that the adjustment frame 21 can move in a direction perpendicular to the swing frame 20. The top of the adjustment frame 21 has a filling platform 211 adapted to the blanking hole 201. Before deciding to discharge the plastic through the discharge barrel 35, the filling platform 211 is blocked at the blanking hole 201. When the swing frame 20 lifts the material back and forth, the material will not fall to the discharge barrel 35. The material will undergo multiple magnetic iron removal processes to effectively absorb the iron in the material. One swing cycle of the swing frame 20 has two lifting processes, which lift the material through the left and right areas respectively, so that the material moves in an inclined direction and is more easily adsorbed on the side wall of the adsorption tank. After the iron material is completely adsorbed and collected in the iron collecting box 34, the adjustment frame 21 is adjusted downward, and the filling platform 211 moves downward. A blanking channel is formed between the top of the filling platform 211 and the bottom of the blanking hole 201. When the swing frame 20 and the screening adjustment assembly swing, the plastic can effectively fall down through the blanking channel into the discharge barrel 35 and finally be discharged from the discharge barrel 35.

[0040] When discharging plastic, the position of the adjustment frame 21 can be adjusted multiple times to sequentially adjust the discharge channels of various specifications with gradually increasing sizes, thereby discharging plastic scraps of gradually increasing sizes. The plastic scraps of gradually increasing sizes are successively collected by multiple containers below the discharge cylinder 35. Plastic scraps that are too large can be crushed again.

[0041] The bottom of the adjustment frame 21 is equipped with a connecting frame 251. A first folding tube, located on the outer periphery of the screw rod 23, is connected between the connecting frame 251 and the adjustment frame 21, as well as between the adjustment frame 21 and the motor 22. This first folding tube protects the screw rod 23, preventing plastic debris from affecting the smooth transmission connection between the components. The bottom of the guide rod 24 is equipped with an end plate 252. A second folding tube, located on the outer periphery of the guide rod 24, is connected between the end plate 252 and the adjustment frame 21, as well as between the adjustment frame 21 and the swing frame 20. This second folding tube protects the guide rod 24. The folding tube is a pleated, cylindrical structure that can be folded and stretched.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
