Description

Technical Field

[0001] This invention belongs to the field of comprehensive utilization technology of solid waste, specifically a plastic recycling device. Background Technology

[0002] Solid waste refers to solid and mud-like substances discarded by humans in production and daily life activities. It includes solid particles separated from wastewater and exhaust gases. All solid or semi-solid substances generated by human activities that no longer have any use value to their owners and are therefore discarded are collectively referred to as solid waste. Most solid waste still contains components needed by other production industries. Through certain technological processes, it can be transformed into raw materials for relevant departments and industries, or even used directly, thereby achieving social recycling of resources, reducing the amount of waste disposal, and benefiting social development.

[0003] Plastic products are very common in our daily lives, resulting in a huge amount of plastic solid waste. In order to achieve comprehensive utilization of solid waste, it is necessary to recycle and regenerate plastic solid waste. The plastic solid waste recycling process mainly involves: collecting waste plastics, sorting and cleaning them, crushing them into small pieces, melting and plasticizing them, extruding them into molds, cooling and solidifying them to obtain recycled plastic products. This process reduces environmental pollution, saves resources, and promotes sustainable development.

[0004] A Chinese patent with publication number CN118418336A discloses a plastic recycling device, including a plastic cleaning module. A conveying module is installed on the upper side of the plastic cleaning module, and a crushing box is installed at the lower end of the plastic cleaning module. The device mainly uses the cleaning components in the cleaning section to clean the surface once, and then uses the restoration section to clean the scratches or dirt a second time by heating at high temperature. This solves the problem of large surface area and many impurities, thereby improving the recycling quality of plastic.

[0005] While the above-mentioned technical solutions can clean impurities from the surface of sheet-shaped plastics, after the sheet-shaped plastics are conveyed to the next crushing process, the crushing components process the sheet-shaped plastics. Due to the elasticity of the sheet-shaped plastics, they tend to bounce and move in all directions during crushing and adhere to both sides, making it difficult for the cutting head to cut them. This results in longer crushing time, affects the crushing effect, and makes it difficult to recycle the plastics, thus having certain limitations. Therefore, the present invention provides a plastic recycling device to solve the above problems. Summary of the Invention

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Combination Figure 1 and Figure 2As shown in the embodiment of the present invention, a plastic recycling device is applicable to a plastic solid waste crusher, including a mounting plate 1, a support section 2 fixedly connected to the top of the mounting plate 1, a crushing section 3 fixedly connected to the top of the support section 2, a feeding port 4 opened at the top of the crushing section 3, a crushing blade 6 rotated inside the crushing section 3, one end of the crushing blade 6 being connected to the output end of a servo motor, the crushing blade 6 having a rotating shaft, two electromagnets 61 fixedly connected to the outside of the rotating shaft, a swing plate 7 installed on the inner wall of the crushing section 3, a processing component rotated to the end of the swing plate 7, the processing component squeezes the crushed sheet-shaped plastic solid waste by swinging the upper and lower parts sequentially in the horizontal direction, facilitating the processing of the sheet-shaped plastic. The residue after crushing solid waste undergoes secondary processing. A high-temperature melting box 8 is fixed between the crushing section 3 and the support section 2. A forming box 9 is fixed to the bottom of the high-temperature melting box 8 and inside the support section 2. A discharge hopper 5 is fixed to the bottom of the support section 2. During operation, this equipment is primarily used in the crushing workshop of a plastic solid waste plant. During the crushing process, sheet-shaped plastic solid waste splashes in all directions, often landing on the two inner walls of the crushing section 3. This prevents the crushing blades 6 from contacting the remaining sheet-shaped plastic solid waste, making secondary crushing difficult. Consequently, the time required for subsequent plastic solid waste regeneration into granules increases. Using this embodiment of the invention, the cleaned waste sheet-shaped plastic solid waste is first fed into the crushing section 3. The sheet-shaped plastic waste is fed into the crushing section 3 through four inlets. After contact with the crushing blades 6, the waste is broken into multiple fragments. These fragments splash onto the inner walls of the crushing section 3. The servo motor is then energized, causing the crushing blades 6 to rotate. The crushing blades 6, in turn, rotate the electromagnet 61. As the electromagnet 61 rotates, its longer portion contacts the processing component. Each rotation of the electromagnet 61 attracts the processing component once. The electromagnet 61 and the processing component are magnetically matched; the electromagnet 61 is the positive pole, and the processing component is the negative pole. The rotation of the electromagnet 61 attracts the processing component. The top of the processing component moves towards the crushing blade 6, squeezing the plastic solid waste fragments that are splashing to both sides towards the center. The plastic solid waste fragments are crushed again by the crushing blade 6, reducing the amount of plastic solid waste fragments hidden on the inner walls of the crushing section 3, thus saving time spent on the recycling of plastic solid waste. After the processing component is adsorbed, it rotates past the magnetic position, and the electromagnet 61 loses its magnetism and automatically resets. Then, the plastic solid waste fragments are melted in the high-temperature melting box 8. After melting, the plastic solid waste is extruded by extrusion, and then cooled by the forming box 9 to produce granules. Finally, the plastic solid waste granules are cut by rotation and discharged through the discharge hopper 5, realizing the recycling process.

[0034] Combination Figures 4 to 6As shown, the processing assembly includes two inclined plates 71, each with an electromagnet 72 fixedly connected to its side. Multiple extrusion plates 74 are fixedly connected to the inner wall of each inclined plate 71, and a limiting plate 75 is fixedly connected below the inner surface of each extrusion plate 74. A rubber plate 70 is fixedly connected to the bottom of each inclined plate 71. Multiple evenly distributed slots are provided on the limiting plate 75. A rotating shaft 2 is located at the top of the swing plate 7, and its outer periphery is fixedly connected to the inclined plate 71. Torsion springs are located inside the rotating shaft 2 and the swing plate 7. During operation, in the process of crushing the sheet-shaped plastic, using this embodiment of the invention, the crushing blade 6 rotates after being energized to crush the added sheet-shaped plastic. The crushing blade 6 cuts the sheet-shaped plastic into fragments, and the plastic fragments are crushed... The cutting of the blade 6 causes plastic fragments to fly in all directions. Some plastic fragments move upwards, fall down, and are cut again. Other plastic fragments move to the sides and come into contact with the swing plate 7. The rotation of the crushing blade 6 will drive the electromagnet 1 61 to move synchronously. When the electromagnet 1 61 rotates past the position of the electromagnet 2 72, the electromagnet 1 61 attracts the electromagnet 2 72, and the electromagnet 2 72 deflects. The electromagnet 2 72 drives the inclined plate 71 to deflect. The inclined plate 71 drives the rotating shaft 2 to rotate at the top of the swing plate 7. The inclined plate 71 deflects and moves towards the crushing blade 6, squeezing the flying plastic fragments back to their original position, accelerating the secondary crushing of the plastic fragments, improving the crushing efficiency, and saving the time required for plastic recycling crushing.

[0035] The top of the inclined plate 71 moves toward the direction of the crushing cutter 6, and the bottom of the rubber plate 70 moves in the opposite direction toward the inner wall of the crushing section 3. The rubber plate 70 contacts the inner wall of the crushing section 3 and shakes the inner wall of the crushing section 3 to reduce the debris adhering to the inner wall of the crushing section 3. The debris falls down through the through groove in the middle of the swing plate 7, thereby reducing the adhesion of debris to the two inner walls of the crushing section 3 by the rubber plate 70, while preventing frequent collisions from damaging the inner wall of the crushing section 3.

[0036] As the top of the inclined plate 71 moves towards the crushing cutter 6, the extrusion plate 74 blocks the plastic fragments on the crushing cutter 6. The extrusion plate 74 reduces the internal plastic fragments from splashing to both sides, preventing excessive debris from splashing onto the inner walls of the crushing section 3.

[0037] Combination Figure 7As shown, a cleaning assembly is installed on the inner wall of the inclined plate 71. The cleaning assembly is used to clean the plastic fragments left when the crushing blade 6 cuts on the outside. The cleaning assembly includes an adhesive plate 711 installed on the inner wall of the crushing section 3. An electric telescopic cylinder 712 is fixedly connected to the center of the adhesive plate 711. A rotating groove 713 is opened on the inner surface of the electric telescopic cylinder 712. A sliding rod 714 is slidably connected inside the rotating groove 713. The electric telescopic cylinder 712 has a telescopic rod inside. The sliding rod 714 is connected to the telescopic rod. The end of the telescopic rod is fixedly connected to a fixed plate 715. A rotating blade 716 is fixedly connected to the top of the fixed plate 715. The diameter of the electric telescopic cylinder 712 is adapted to the groove diameter of the limiting plate 75. The electric telescopic cylinder 712 is located below the groove of the limiting plate 75. The fixed plate 715 is connected to the telescopic rod. When the telescopic rod is retracted inside the electric telescopic cylinder 712, the length occupied by the multiple rotating blades 716 does not exceed the extrusion plate 74. During operation, during crushing... After the plastic recycling process is completed, the plastic fragments adhering to the outside of the crushing blade 6 need to be cleaned in time. In this embodiment of the invention, the internal telescopic rod of the electric telescopic cylinder 712 is rotated when energized. The rotation of the telescopic rod drives the sliding rod 714 to move. The sliding rod 714 slides along the path of the rotating groove 713. The telescopic rod rotates and extends out of the electric telescopic cylinder 712 with linear motion. The telescopic rod pushes the rotating blade 716 to move. Multiple rotating blades 716 move synchronously. After multiple rotating blades 716 come into contact with the outside of the stopped crushing blade 6, the plastic fragments adhering to the outer surface of the crushing blade 6 are scraped off by the multiple rotating blades 716 under the friction between the two. Finally, water only needs to be added from the feed port 4 to rinse the crushing blade 6 again to complete the cleaning of the plastic fragments adhering to the outer surface of the crushing blade 6. The scraping process improves the cleaning efficiency and the convenience of cleaning.

[0038] Due to the frequent movement of the inclined plate 71, which pushes the plastic fragments around the outer periphery of the crushing blade 6, and because the inclined plate 71 drives the bonding plate 711 and the electric telescopic cylinder 712 to move, the electric telescopic cylinder 712 is prone to internal vibration due to long-term movement. After prolonged vibration, the telescopic rod may easily extend out of the electric telescopic cylinder 712 and become disengaged. Therefore, when the top of the inclined plate 71 moves towards the outer periphery of the crushing blade 6, the tilting of the pressing plate 74 will cause the limiting plate 75 to tilt. The limiting plate 75 is locked on the outer periphery of the electric telescopic cylinder 712, and the limiting plate 75 forms a fixation for the electric telescopic cylinder 712. The limiting plate 75 blocks the side of the telescopic rod's extension path, preventing the electric telescopic cylinder 712 from becoming disengaged during frequent swinging.

[0039] Combination Figures 8 to 10As shown, the forming box 9 includes a gathering assembly installed inside the support section 2. The gathering assembly includes multiple receiving plates 91, with a transition plate 92 fixed between two receiving plates 91. A spring element 93 is fixed to the inner surface of the receiving plate 91 and is connected to the inner wall of the forming box 9. A rotating rod 94 is rotatably connected inside the forming box 9. An extrusion roller 95 is fixed to the outer periphery of the rotating rod 94. A second servo motor is connected to the outside of the rotating rod 94, and the output end of the second servo motor is connected to one end of the rotating rod 94. A cooling section 96 is fixed to the bottom of the forming box 9. A screen 97 is installed at the bottom of the cooling section 96. A dividing shaft 99 is rotatably connected to the center of the cooling section 96. A deflector 98 is fixedly connected to the outside of shaft 99, and a steel wire rod 90 is drivenly connected to the outer surface of rotating rod 94. Multiple guide grooves 81 are formed on the upper surface of high-temperature melting box 8, with the center of each groove recessed downwards. Multiple through holes are formed inside screen 97 to define the shape of the recycled plastic, ensuring consistent shape of the extruded recycled plastic. The screen 97 is the same size as the bottom of cooling section 96. A steering wheel is connected to the upper surface of mounting plate 1 at the bottom of support section 2, and the steel wire rod 90 is connected to the dividing shaft 99 via the steering wheel. The deflector 98 is located inside discharge hopper 5, and the bottom of cooling section 96 is connected to the top of one side of discharge hopper 5. During operation, after pre-processing such as crushing, when the sheet plastic is recycled, the plastic fragments gradually fall to the upper surface of the high-temperature melting box 8 and slide towards the central recessed position through the guide groove 81. The plastic fragments are melted by the high temperature treatment of the high-temperature melting box 8, and the melted plastic fragments gradually flow down into the interior of the forming box 9. At this time, the second servo motor is driven, which drives the rotating rod 94 to rotate. The rotation of the rotating rod 94 drives the extrusion roller 95 and the wire rod 90 to move. When the extrusion roller 95 rotates, it conveys the fallen and accumulated plastic fragments, spreads the accumulated and melted plastic fragments, and melts them. The plastic fragments continue to flow down the bottom of the molding box 9 and enter the interior of the cooling section 96. They pass through the through holes of the screen 97 and continue downward. When the rotating rod 94 rotates, it drives the steel wire rod 90 to move. The steel wire rod 90 drives the dividing shaft 99 to rotate. The rotation of the dividing shaft 99 drives the agitator 98 to move. The agitator 98 agitates the plate-shaped plastic that passes through the screen 97, and finally pushes out the recycled plastic, achieving the purpose of rapid recycling. It should be noted that the cooling section 96 needs time to cool the melted plastic fragments and will not freeze them completely in a short time to prevent them from moving downward.

[0040] Working principle: In the process of crushing sheet-shaped plastics, using the embodiment of this invention, the crushing blade 6 rotates after being energized to crush the added sheet-shaped plastics. The crushing blade 6 cuts the sheet-shaped plastics into fragments. The plastic fragments are splashed in all directions due to the cutting of the crushing blade 6. Some plastic fragments move upward and are cut again after falling. Other plastic fragments move to both sides and come into contact with the swing plate 7. The rotation of the crushing blade 6 will drive the electromagnet 1 61 to move synchronously. When the electromagnet 1 61 rotates past the position of the electromagnet 2 72, the electromagnet 1 61 attracts the electromagnet 2 72, and the electromagnet 2 72 deflects. The electromagnet 2 72 drives the inclined plate 71 to deflect. The inclined plate 71 drives the rotating shaft 2 to rotate at the top of the swing plate 7. The inclined plate 71 deflects and moves towards the crushing blade 6, squeezing the splashed plastic fragments back to their original position, accelerating the secondary crushing of the plastic fragments, improving the crushing efficiency, and saving the time required for plastic recycling crushing.

[0041] The top of the inclined plate 71 moves toward the direction of the crushing cutter 6, and the bottom of the rubber plate 70 moves in the opposite direction toward the inner wall of the crushing section 3. The rubber plate 70 contacts the inner wall of the crushing section 3 and shakes the inner wall of the crushing section 3 to reduce the debris adhering to the inner wall of the crushing section 3. The debris falls down through the through groove in the middle of the swing plate 7, thereby reducing the adhesion of debris to the two inner walls of the crushing section 3 by the rubber plate 70, while preventing frequent collisions from damaging the inner wall of the crushing section 3.

[0042] As the top of the inclined plate 71 moves towards the crushing blade 6, the extrusion plate 74 blocks the plastic fragments on the crushing blade 6. The extrusion plate 74 reduces the internal plastic fragments from splashing to both sides, preventing excessive debris from splashing onto the inner walls of the crushing section 3.

[0043] After pre-processing such as crushing, during the recycling of the sheet-shaped plastic, the plastic fragments gradually fall onto the upper surface of the high-temperature melting chamber 8 and slide towards the central recessed position through the guide groove 81. The plastic fragments are melted by the high-temperature melting chamber 8, and the melted plastic fragments gradually flow down into the interior of the molding box 9. At this time, the second servo motor is driven, which drives the rotating rod 94 to rotate. The rotation of the rotating rod 94 drives the extrusion roller 95 and the wire rod 90 to move. When the extrusion roller 95 rotates, it conveys the fallen and accumulated plastic fragments and spreads the accumulated and melted plastic fragments. The plastic sheet continues to flow down the bottom of the forming box 9 and enters the interior of the cooling section 96. It passes through the through holes of the screen 97 and continues downward. When the rotating rod 94 rotates, it drives the steel wire rod 90 to move. The steel wire rod 90 drives the dividing shaft 99 to rotate. The rotation of the dividing shaft 99 drives the agitator 98 to move. The agitator 98 agitates the sheet-shaped plastic that passes through the screen 97 and finally pushes out the recycled plastic, achieving the purpose of rapid recycling. It should be noted that the cooling section 96 needs time to cool the melted plastic fragments and will not freeze them completely in a short time to prevent them from hindering downward movement.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
