[0009] Preferably, the driving mechanism includes a driving rod, a rack, and a gear. The driving rod is fixedly connected to the piston rod end of the cylinder. The rack is fixedly connected to the end of the driving rod away from the cylinder. The gear is fixedly connected inside the baffle and movably sleeved on the rod wall of the fixed rod. The gear meshes with the rack.

[0010] Preferably, a guide slider is fixedly connected to the side wall of the rack, a rectangular opening is provided on the inner wall of the partition, a guide groove is provided on the inner wall of the partition located at the rectangular opening, and the guide slider is slidably disposed on the inner wall of the guide groove.

[0013] Preferably, a pull rod is fixedly connected to the side wall of the limiting plug, and a strip-shaped opening is provided on the inner wall of the connecting frame located in the cavity, with the rod wall of the pull rod slidably disposed on the inner wall of the strip-shaped opening.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a device for separating aluminum and plastic from waste plastic sheets, which has the following beneficial effects: 1. The device for separating aluminum and plastic from waste plastic boards uses a separation medium liquid filled at the bottom with a density between that of aluminum and plastic, which is the key to achieving aluminum-plastic separation. By utilizing the density difference between aluminum (high density) and plastic (low density), the cut aluminum particles sink to the bottom of the medium liquid, while the plastic particles float on the surface of the medium liquid, thus completing the physical separation. The discharge pipe at the bottom of the tank is used to discharge the separated aluminum particles and medium liquid.

[0015] 2. The device for separating aluminum from plastic waste boards uses a drive rod fixed at the end of a cylinder piston rod to move a rack. The rack meshes with a gear fixed inside a baffle. When the rack slides, it drives the gear to rotate, which in turn causes the baffle to rotate around the fixed rod, thus opening and closing the opening. This allows the crushed waste plastic to be placed into the separation medium liquid.

[0016] 3. This device for separating aluminum from waste plastic boards can intercept floating plastic particles through the filter screen on the inner wall of the connecting frame, preventing plastic from escaping with the liquid vapor or mixing into the aluminum particles. The activated carbon adsorption particles filled in the gaps of the filter screen can help adsorb oil or impurities on the surface of the plastic, further improving the purity of the plastic particles and facilitating subsequent recycling. The metal elastic strip in the cavity pushes the limiting block into the limiting slot of the box, firmly fixing the connecting frame in the rectangular opening. Attached Figure Description

The bottom of the housing 1 is filled with a separation medium liquid 17. A rectangular opening is provided on the inner wall of the housing 1 above the separation medium liquid 17. An opening is provided on the inner wall of the partition 5. A fixing rod 6 is fixedly connected to the inner wall of the opening. A baffle 7 is movably sleeved on the wall of the fixing rod 6. The baffle 7 is located inside the opening. A notch is provided inside the baffle 7. A cylinder 10 is fixedly connected to the side wall of the housing 1.

[0021] The top of the housing 1 is fixedly connected to the feed hopper 2, which is cone-shaped. The partition 5 is located on the inner wall of the opening and is fixedly connected to the first rubber pad 8. The first rubber pad 8 is pressed and set on the side wall of the baffle 7. The inner wall of the baffle 7 is fixedly connected to the second rubber pad 9.

[0022] A drive mechanism is provided above the baffle 7. The drive mechanism includes a drive rod 11, a rack 12 and a gear 13. The drive rod 11 is fixedly connected to the piston rod end of the cylinder 10. The rack 12 is fixedly connected to the end of the drive rod 11 away from the cylinder 10. The gear 13 is fixedly connected inside the baffle 7 and movably sleeved on the rod wall of the fixed rod 6. The gear 13 is meshed with the rack 12.

[0023] A guide slider 14 is fixedly connected to the side wall of the rack 12. A rectangular opening is provided on the inner wall of the partition 5. A guide groove is provided on the inner wall of the partition 5 located at the rectangular opening. The guide slider 14 is slidably disposed on the inner wall of the guide groove. A rubber buffer pad 15 is fixedly connected to the end of the rack 12 away from the drive rod 11. The end of the rubber buffer pad 15 away from the rack 12 is set as an arc surface.

[0024] A connecting frame 18 is inserted into the inner wall of the rectangular opening of the box 1. A filter screen 19 is fixedly connected to the inner wall of the connecting frame 18. A cavity is opened in the inner wall of the connecting frame 18. A metal elastic strip 20 is fixedly connected to the inner wall of the cavity. A limit block 21 is fixedly connected to the bottom of the metal elastic strip 20. A limit slot is opened in the inner wall of the rectangular opening of the box 1. The limit block 21 is inserted into the inner wall of the limit slot. A pull rod 22 is fixedly connected to the side wall of the limit block 21. A strip-shaped opening is opened in the inner wall of the cavity of the connecting frame 18. The rod wall of the pull rod 22 is slidably disposed in the inner wall of the strip-shaped opening.

[0025] The housing 1 is the core operating space for aluminum-plastic separation. The motor 3 fixed to the top side wall provides power for cutting and crushing. The separation medium liquid 17 filled at the bottom has a density between aluminum and plastic, which is the key to achieving aluminum-plastic separation. By utilizing the density difference between aluminum (high density) and plastic (low density), the cut aluminum particles sink to the bottom of the medium liquid, while the plastic particles float on the surface of the medium liquid, thus completing the physical separation. The discharge pipe 16 at the bottom of the housing 1 is used to discharge the separated aluminum particles and medium liquid. The conical feed hopper 2 fixed at the top facilitates the centralized feeding of waste plastic boards into the device, avoiding material scattering during feeding.

[0026] The cutting spindle 4 is rotatably connected to the inner wall of the top of the housing 1. Its end is fixedly connected to the output shaft of the motor 3. After the motor 3 starts, it directly drives the cutting spindle 4 to rotate at high speed. The cutting tools on the cutting spindle 4 can cut and crush the waste plastic board fed from the feed hopper 2 into fine particles, increase the contact area between aluminum and plastic, and create conditions for subsequent density separation.

[0027] A baffle 7 is movably fitted onto a fixed rod 6 at the opening of the inner wall of the box 1. The baffle 7 can be opened and closed by rotating it. A drive rod 11 fixed at the end of the piston rod of the cylinder 10 drives the rack 12 to move. The rack 12 meshes with the gear 13 fixed inside the baffle 7. When the rack 12 slides, it drives the gear 13 to rotate, thereby causing the baffle 7 to rotate around the fixed rod 6, thus realizing the opening and closing of the opening. The crushed waste plastic can be put into the separation medium liquid 17.

[0028] The guide slider 14 on the side wall of the rack 12 is slidably disposed in the guide groove of the partition 5 to ensure that the rack 12 moves only in a straight line and to avoid misalignment between the gear 13 and the rack 12; the rubber buffer pad 15 at the end of the rack 12 can reduce the impact force when the rack 12 moves to the limit position and extend the service life of the component.

[0029] The first rubber pad 8 on the inner wall of the opening of the partition 5 is pressed against the side wall of the baffle 7, and the second rubber pad 9 on the inner wall of the baffle 7 further enhances the sealing effect, preventing fine particles from splashing out of the opening gap to the outside of the device during the cutting process, and at the same time preventing water vapor from the medium liquid from seeping upward into the cutting area and causing the components to rust.

[0030] After cutting, the aluminum-plastic granules fall into the separation medium liquid 17 through the opening of the partition 5. The aluminum granules have a higher density than the separation medium liquid 17, so they sink to the bottom of the tank 1 under the action of gravity. The plastic granules have a lower density than the separation medium liquid 17, so they float on the surface of the medium liquid, thus forming a clear initial separation.

[0031] The housing 1 is located in a rectangular opening above the separating medium liquid 17. A connecting frame 18 is inserted into it. The filter screen 19 on the inner wall of the connecting frame 18 can intercept floating plastic particles, preventing plastic from escaping with the medium liquid vapor or mixing into the aluminum particles. The activated carbon filling the gaps of the filter screen 19 can adsorb particles, which can help adsorb oil or impurities on the surface of the plastic, further improving the purity of the plastic particles and facilitating subsequent recycling. The metal elastic strip 20 in the cavity pushes the limiting plug 21 into the limiting slot of the housing 1, which firmly fixes the connecting frame 18 in the rectangular opening. When it is necessary to clean the filter screen 19 or replace the activated carbon, pull the pull rod 22 on the side wall of the limiting plug 21 to compress the metal elastic strip 20 and make the limiting plug 21 disengage from the limiting slot, so that the connecting frame 18 can be removed. The operation is convenient and does not require tools.
