Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This implementation example Figures 1-11As shown. Example

[0023] A plastic waste recycling and reprocessing device includes a support 1, a sorting pool 2 disposed on the inner side of the support 1, a conveyor 4 disposed at one end of the support 1, a mounting frame 5 disposed on the top of the support 1 and near the conveyor 4, a cutting assembly disposed on the inner side of the mounting frame 5, a cutting table 17 disposed on the top of the support 1 and directly below the cutting assembly, the cutting table 17 and the conveyor 4 being disposed on the same plane, a feeding assembly disposed between the cutting table 17 and the conveyor 4, a driving unit disposed inside the cutting table 17, the driving unit cooperating with the feeding assembly, a sorting assembly disposed on the inner side of the sorting pool 2, and an arc-shaped guide plate 14 disposed at one end of the support 1, the arc-shaped guide plate 14 being located below the cutting table 17.

[0024] The slitting assembly includes a slitting section 6, a cam 28, and a drive shaft 29. The slitting section 6 is located inside the mounting bracket 5. The top of the slitting section 6 is open, and the bottom of the slitting section 6 has several sets of telescopic holes at equal intervals. One end of the drive shaft 29 passes through the slitting section 6, and the other end is movably connected to the inside of the slitting section 6. The cam 28 is located at equal intervals on the outside of the slitting section 6, and the cam 28 is a combination of three semi-cylindrical units.

[0025] A drive motor 7 is provided on the drive shaft 29 protruding from one end of the dividing section 6. The output end of the drive motor 7 is connected to the drive shaft 29 through a coupling. The drive motor 7 is fixedly installed on the side of the mounting bracket 5 through a motor frame. The entire cutting assembly is driven by the drive motor 7, and the width of the strip plastic can be adjusted according to the speed of the drive motor 7.

[0026] The slitting assembly also includes a pressure rod 24, a pressure block 25, a cutting blade 26, and a spring post 27. The pressure block 25 is movably disposed within the telescopic hole. The spring post 27 is disposed at the bottom of the slitting section 6 and located on both sides of the telescopic hole. The cutting blade 26 is disposed at the bottom end of the pressure block 25. The pressure rod 24 is disposed through the cutting blade 26. The pressure block 25 is fitted onto the spring post 27 via side lugs on both sides. A slitting blade is disposed at the bottom end of the pressure rod 24 to perform strip cutting on the plastic sheet. The spring post 27 fitted onto the side lugs is used to limit and reset the pressure block 25, thereby ensuring consistent operation of the entire slitting assembly.

[0027] The feeding assembly includes a rack 22, a pressure roller 15, a drive roller 16, and a drive unit. The rack 22 is fixedly installed on the side of the feeding assembly. The pressure roller 15 and the drive roller 16 are arranged between the slitting table 17 and the conveyor table 4. The pressure roller 15 and the drive roller 16 are installed on the inner surface of the conveyor table 4 through a connecting piece. The drive roller 16 is connected to the conveyor table 4 through a ratchet bearing and can only rotate clockwise. The component connected to the conveyor table 4 is provided with a sliding groove, and a spring is provided inside the sliding groove. The surface of the slitting table 17 is provided with a telescopic hole through which the rack 22 passes. The drive unit is movably installed on the inner side of the slitting table 17.

[0028] The drive unit includes a one-way gear 23, which meshes with the drive roller 16. The rack 22 is arranged in a "7" shape and has teeth on its surface. There are two sets of one-way gears 23 symmetrically arranged at both ends of the drive motor 7.

[0029] The surface of the slitting table 17 is provided with several sets of square slots 21 at equal intervals. The square slots 21 are used in conjunction with the feeding assembly. Sheet-shaped plastic pieces pass through the pressure roller 15 and the drive roller 16. The plastic is cut by the cutting blade 26 and enters the square slots 21 and is discharged and collected through the arc-shaped guide plate 14.

[0030] Operation process: By energizing the drive motor 7, the transmission shaft 29 is driven to rotate. The transmission shaft 29 drives the outer cam 28 to rotate. When the cam 28 moves to the lowest point, it will completely squeeze the pressure block 25, thereby driving the cutting blade 26 and the pressure rod 24 to punch and cut the plastic sheet conveyed by the conveyor table 4. The plastic sheet will be punched into sheet and strip. The sheet plastic blocks are discharged through the square slot 21 to the arc guide plate 14 for collection. The plastic strips cut into strips enter the cleaning chamber 20 opened at the front of the sorting tank 2. As the cutting proceeds, more and more plastic strips accumulate in the cleaning chamber 20. When the specified amount is cut, it can also be selected according to the requirements of recycling and processing for subsequent cleaning and sorting. It should be noted that when the pressure rod 24 moves up and down periodically with the pressure block 25, it drives the rack 22 to move along the telescopic hole. When the pressure rod 24 is moving downward, the one-way gear 23 rotates clockwise. At this time, the drive roller 16 is limited by the ratchet bearing and cannot rotate. The one-way gear 23 pushes the drive roller 16 open along the mounting groove and deflects it, and squeezes the spring. The one-way gear 23 separates from the drive roller 16 and rotates on its own. When the pressure rod 24 is moving upward, the one-way gear 23 rotates counterclockwise. At this time, the drive roller 16 moves closer to the one-way gear 23 under the action of the mounting groove and the spring and rotates the drive roller 16, thereby realizing the conveying of the plastic sheet between the pressure roller 15 and the drive roller 16 to the bottom of the slitting assembly.

[0031] Example 2: This embodiment differs from the first embodiment in that: a sorting pool 2 is provided on the inner side of the support 1, a sorting component is provided on the inner side of the sorting pool 2, a discharge trough 8 and an inlet pipe 10 are respectively provided on both sides of the sorting pool 2, and an interception component is provided on the inner wall of the sorting pool 2 located on the side of the discharge trough 8.

[0032] The outer side of the sorting tank 2 is provided with valve pipe 3, which consists of two sets of valve pipe 3 respectively located on the outer side of the sorting tank 2, one set being the input and the other the output. The middle part of the sorting tank 2 is provided with a cleaning chamber 20, which is inclined to avoid excessive accumulation of plastic strips, thereby achieving stratification.

[0033] The sorting assembly includes a deflection motor 9 and an overflow interceptor plate 11. The deflection motor 9 is located on the side of the sorting tank 2, and there are several sets of deflection motors 9. The overflow interceptor plate 11 is located on the inside of the sorting tank 2, and the side of the overflow interceptor plate 11 is fixedly connected to the output end of the deflection motor 9.

The valve seat 19 is fixedly installed on the bottom surface of the sorting tank 2 and protrudes from the inner bottom wall of the sorting tank 2. The valve plate 13 is movably disposed inside the valve seat 19. A discharge port is provided on the side of the sorting tank 2, and the discharge port is connected to the discharge trough 8. The valve plate 13 and the discharge port are initially closed. The screening of plastic strips floating on the upper layer of the sorting liquid is achieved by controlling the opening and closing degree of different valve plates 13 and the discharge port. The adjustment of the valve seat 19 and the valve plate 13 is controlled by the snap-lock positioning to control the extension and retraction length of the valve plate 13.

[0035] The rest of the structure is the same as in Example 1.

[0036] Operation process: Strip-shaped plastic strips fall into the divided cleaning chambers 20 of the sorting tank 2. Cleaning liquid is injected through the valve pipe 3 to clean the surface of the plastic strips. External stirring equipment can be used to stir and scrub the floating plastic parts to clean the surface impurities. The wastewater after cleaning is discharged through another set of valve pipes 3. Optionally, a dividing screen can be set inside the cleaning chamber 20 to separate the cleaned plastic strips from the impurities. The cleaning can be performed at least twice to ensure that there are fewer impurities on the surface of the plastic strips. The cleaned plastic strips can be put into multiple sets of divided sorting tanks 18 and sorting liquids of different densities are injected into them. The valve plate 13 in the interception component is adjusted according to the different layers of the plastic strips in the sorting liquid. Specifically, the discharge port is adjusted from small to large so that the plastic strips suspended in the upper, middle and lower layers are discharged. Optionally, a single divided sorting tank 18 can also be used to screen plastic strips by injecting sorting liquids of different densities, or multiple sets of sorting tanks 18 can be used to screen with sorting liquids of different densities. One possible solution is to use a separation liquid with a density gradient of 1.5 g / cm³ → 2.0 g / cm³ → 2.5 g / cm³, forming a gradually increasing density gradient field to accommodate the density differences of different plastics. By utilizing the density differences of materials such as PE (0.91 g / cm³), ABS (1.05 g / cm³), and PVC (1.38 g / cm³), layered floating separation can be achieved.
