Description

Technical Field

[0001] This invention belongs to the technical field of waste plastics, and more specifically, it is a multifunctional processing device for recycling waste plastics. Background Technology

[0002] This multi-functional waste plastic recycling device is used in the process of recycling waste plastics to clean, dry, crush, and pack them. It can improve the processing efficiency of waste plastics and optimize the processing method.

[0003] Patent document CN111571871A discloses a pre-treatment device for recycling waste plastic bottles, including a mounting box. A feeding device extending into the top of the mounting box is installed therein. A baffle is welded to each of the left and right sides inside the mounting box. A compression mechanism is installed above the two baffles and on the mounting box itself. A feeding mechanism is installed at the top inside the mounting box. A crushing mechanism is installed below the baffles inside the mounting box. A washing box is installed below the mounting box on the ground, and a turning mechanism extending into the washing box is installed therein. This device facilitates the compression, crushing, and cleaning of plastic bottles.

[0004] The aforementioned device has certain shortcomings in waste plastic processing. Waste plastic processing involves multiple steps, requiring separate cleaning, drying, crushing, and packaging. Different operations require different equipment, and the device can only perform crushing, failing to complete the entire processing flow sequentially. This reduces the efficiency of waste plastic processing and limits its functionality. Secondly, the device lacks an auxiliary puncture function. When crushing waste plastic, the plastic bottles need to be pre-opened to prevent them from bursting during compression. Thirdly, the device lacks an auxiliary drying structure. The washed plastic bottles contain a large amount of moisture, and direct crushing can easily corrode the equipment. Furthermore, the crushed plastic particles contain a large amount of moisture, increasing the number of subsequent processing steps and reducing its effectiveness. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional processing device for recycling waste plastics, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. The processing of waste plastics involves multiple steps, requiring separate cleaning, drying, crushing, and packaging operations. Different operations require different equipment. The aforementioned device can only perform crushing and cannot complete the entire processing flow sequentially, thus reducing the processing efficiency of waste plastics and having limited functionality.

[0008] 2. The above device does not have an auxiliary puncture function. When crushing waste plastics, the plastic bottles need to be opened beforehand to avoid the plastic bottles bursting when squeezed.

[0009] 3. The above-mentioned device does not have an auxiliary drying structure. The cleaned plastic bottles contain a lot of moisture. Direct crushing will easily cause the equipment to rust. Moreover, the crushed plastic particles contain a lot of moisture, which increases the number of subsequent processing steps and reduces the effectiveness of the device.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A multifunctional processing device for recycling waste plastics includes a fixed base and a washing tank. The washing tank is fixedly installed on the upper end of the fixed base. A washing roller for washing waste plastics is movably installed on the inner side of the upper end of the washing tank. Both ends of the washing roller and the washing tank are movably connected by sliding lifting components. The sliding lifting components have an inverted T-shaped structure. A crushing bin for crushing waste plastics is fixedly installed on the upper end of the washing tank, located on one side of the washing roller. A drying trough for use with the washing roller is provided between the washing roller and the crushing bin. The drying trough has a semi-circular cross-section and several sets of air holes on its outer surface. A telescopic frame for packaging waste plastic granules is movably installed on the inner side of one end of the washing tank, and two sets of sliding racks are movably installed on the inner side of the telescopic frame.

[0012] As a further technical solution of the present invention, a cylindrical mesh plate is fixedly installed on the outer surface of the cleaning drum, and several sets of arc-shaped protrusions are fixedly installed on the inner side of the cleaning drum. One side of a set of sliding lifting parts is provided with a motor for driving the cleaning drum to rotate. A fixed top rod is provided between the fixed base and the cleaning box. The user puts the waste plastic into the cleaning box and starts the motor to drive the cleaning drum to rotate. Water passes through the cylindrical mesh plate and enters the interior of the cleaning drum. During the rotation of the cleaning drum, the waste plastic inside is cleaned. At the same time, the arc-shaped protrusions can collide with the waste plastic when the cleaning drum rotates, preventing the waste plastic from accumulating.

[0013] As a further technical solution of the present invention, an arc-shaped cover plate is movably installed on one side of the cleaning drum. The cleaning drum and the arc-shaped cover plate are movably connected by a rotating shaft. Both sides of the cleaning box are provided with sliding grooves for use with sliding lifting parts. Users can place waste plastic products into the cleaning drum by opening the arc-shaped cover plate and closing the arc-shaped cover plate to prevent the waste products in the cleaning drum from breaking and falling out.

[0014] As a further technical solution of the present invention, the sliding lifting component includes a T-shaped carriage and a lifting rod. The lifting rod is located at the upper middle part of the T-shaped carriage. The upper end of the lifting rod is provided with a docking shaft for use with the cleaning drum. By using the sliding lifting component, the cleaning drum can be lifted and moved for adjustment. When the waste plastic is dried after washing, the user starts the lifting rod and lifts the cleaning drum by electric lifting, so that the cleaning drum moves upward. The water in the cleaning drum is separated by the columnar mesh plate. The cleaning drum is moved as a whole by the T-shaped carriage and moved to the top of the drying tank. Then, the lifting rod drives the cleaning drum to move downward, so that the semi-circular drying tank is semi-enclosed and docks with the cleaning drum, allowing the cleaning drum to rotate inside the drying tank.

[0015] As a further technical solution of the present invention, a docking strip is fixedly installed on the lower side of the T-shaped carriage, and several sets of electric rollers are movably installed on the lower part of the docking strip. Both ends of the docking strip are fixedly installed with buffer heads. By rotating the electric rollers, the T-shaped carriage can be driven as a whole, so that the T-shaped carriage drives the washing drum to move laterally. After the waste plastic in the washing drum is dried, the washing drum is lifted again by the lifting rod, and the washing drum is moved to the upper part of the crushing box by the T-shaped carriage. The arc-shaped cover is opened to discharge the waste plastic in the crushing box for crushing.

[0016] As a further technical solution of the present invention, two sets of dryers are fixedly installed at the lower part of the drying tank. The dryers and the drying tank are connected and fixed through air guide pipes. When the cleaning drum moves to the inside of the drying tank, the dryers and air guide pipes can be used to heat the inside of the drying tank with hot air. With the rotation of the cleaning drum, the hot air passes through the cylindrical mesh plate to dry the waste plastic inside the cleaning drum.

[0017] As a further technical solution of the present invention, the crushing bin includes two sets of crushing rollers and two sets of piercing rollers. The two sets of piercing rollers are movably installed on the upper part of the two sets of piercing rollers. The upper end of the crushing bin is provided with a feed inlet. Several sets of spikes are fixedly installed on the outer surface of the piercing rollers. The user pours the cleaned and dried waste plastic into the crushing bin. By using the rotation of the piercing rollers, the spikes can be used to pierce the bottle-shaped plastic products. At the same time, during the rotation of the piercing rollers, the bottle-shaped plastic products are flattened, thereby expelling the air inside the bottle-shaped plastic products and preventing them from being squeezed and bursting during the crushing process.

[0018] As a further technical solution of the present invention, one end of the two sets of piercing rollers is directly driven by gears, and the other end of the piercing rollers and the crushing rollers are driven by a chain and gears. The lower end of the crushing box is provided with an inclined discharge port. The user drives one set of piercing rollers to rotate by a motor, and the gear drive structure enables one set of piercing rollers to drive the other set of piercing rollers, so that the two sets of piercing rollers rotate synchronously. At the same time, the chain and gears enable the two sets of piercing rollers to drive the two sets of crushing rollers respectively, so that the two sets of crushing rollers rotate synchronously.

[0019] As a further technical solution of the present invention, a movable push plate is movably installed on the inner side of the fixed base, an inclined panel is fixedly installed on the side of the movable push plate, and docking slide buckles are fixedly installed at both ends of the movable push plate. The upper end of the sliding rack is provided with a fixed tooth head, a screen is fixedly installed on the inner side of one end of the crushing box, and a side rotating cover plate is provided at one end of the fixed base.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting up a sliding lifting component and a washing drum, the multi-functional waste plastic recycling processing device allows for flexible adjustment of the washing drum's position using the sliding lifting component. This enables the washing drum to be used in conjunction with the crushing bin, drying tank, and washing tank. Depending on the processing stage of the waste plastic, the waste plastic inside the washing drum is moved to the corresponding position. The washing drum is moved via the sliding lifting component, thus connecting the crushing bin, drying tank, and washing tank in series, achieving continuous washing, drying, crushing, and packaging operations. This integrates the entire waste plastic processing flow, effectively improving the processing efficiency of waste plastic. During operation, the washing drum can be raised, lowered, and moved using the sliding lifting component. Initially, the washing drum is placed inside the washing tank. Starting the motor drives the washing drum to rotate, and water passes through the cylindrical mesh plate into the interior of the washing drum. During the rotation of the washing drum, the waste plastic inside is washed. Simultaneously, the arc-shaped protrusions further enhance the cleaning process. The washing drum rotates and collidees with waste plastics to prevent their accumulation. After washing, during the drying process, the user activates the lifting rod to electrically lift the washing drum, moving it upwards. A cylindrical mesh separates the water inside the drum, and a T-shaped carriage moves the drum as a whole, placing it above the drying trough. The lifting rod then drives the drum downwards, causing the semi-circular drying trough to partially enclose the drum, allowing it to rotate inside for drying. Once the waste plastics are dried, the lifting rod is used again to raise the drum, and the T-shaped carriage moves it to the top of the shredder. The curved cover is then opened to discharge the waste plastics from the shredder for further crushing. The sliding lifting mechanism allows for flexible adjustment of the washing drum's position, facilitating the entire waste plastic processing operation and improving work efficiency.

[0022] 2. By setting up a crushing bin, this multi-functional waste plastic recycling device utilizes the piercing rollers and crushing rollers within the crushing bin to sequentially pierce and crush waste plastics, preventing the plastic bottles from bursting during crushing. During operation, the user pours the cleaned and dried waste plastics into the crushing bin. The rotation of the piercing rollers, combined with the spikes, pierces the plastic bottles. Simultaneously, the rotating piercing rollers flatten the plastic bottles, expelling air and preventing bursting during crushing. The user drives one set of piercing rollers with a motor, and a gear drive mechanism enables one set of piercing rollers to drive another set, ensuring synchronous rotation. A chain and gears further drive the two sets of crushing rollers, ensuring synchronous rotation of both sets. This synchronized rotation of the piercing and crushing rollers improves the stability of the crushing bin during use. The piercing and crushing rollers effectively enhance the crushing effect of waste plastics.

[0023] 3. By setting up a drying trough and a telescopic frame, this multi-functional waste plastic recycling processing device can use the drying trough in conjunction with the washing drum to dry the waste plastic inside the washing drum. The drying trough adopts a semi-circular structure design, while the outer surface of the washing drum is a cylindrical structure, allowing the drying trough to be locked onto the outside of the washing drum. When the washing drum moves to the inside of the drying trough, the dryer, in conjunction with the air guide pipe, can heat the inside of the drying trough with hot air. Combined with the rotation of the washing drum, the hot air passes through the cylindrical mesh plate to dry the waste plastic inside the washing drum, allowing the hot air to fully enter the interior of the washing drum, effectively improving the drying effect of the waste plastic inside the washing drum. Secondly, the telescopic frame uses the fixing teeth of the sliding rack to fix packaging bags of different sizes, facilitating the bagging of the crushed plastic particles after the waste plastic crushing operation is completed in the crushing bin.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0033] like Figure 1-6 As shown, a multifunctional processing device for recycling waste plastics includes a fixed base 1 and a washing tank 9. The washing tank 9 is fixedly installed on the upper end of the fixed base 1. A washing roller 8 for washing waste plastics is movably installed on the inner side of the upper end of the washing tank 9. Both ends of the washing roller 8 and the washing tank 9 are movably connected by a sliding lifting component 13. The sliding lifting component 13 has an overall inverted T-shaped structure. A crushing box 6 for crushing waste plastics is fixedly installed on the upper end of the washing tank 9 on one side of the washing roller 8. A drying trough 7 for use with the washing roller 8 is provided between the washing roller 8 and the crushing box 6. The drying trough 7 has a semi-circular cross-section and several sets of air holes on its outer surface. A telescopic frame 4 for packing waste plastic particles is movably installed on the inner side of one end of the washing tank 9. Two sets of sliding racks 29 are movably installed on the inner side of the telescopic frame 4.

[0034] A cylindrical mesh plate 11 is fixedly installed on the outer surface of the cleaning drum 8, and several sets of arc-shaped protrusions 15 are fixedly installed on the inner side of the cleaning drum 8. A motor 14 for driving the cleaning drum 8 to rotate is provided on one side of a set of sliding lifting parts 13. A fixed top rod 18 is provided between the fixed base 1 and the cleaning tank 9. The user puts the waste plastic into the cleaning tank 9 and starts the motor 14, which drives the cleaning drum 8 to rotate. Water passes through the cylindrical mesh plate 11 and enters the interior of the cleaning drum 8. During the rotation of the cleaning drum 8, the waste plastic inside is cleaned. At the same time, the arc-shaped protrusions 15 can collide with the waste plastic when the cleaning drum 8 rotates, preventing the waste plastic from accumulating.

[0035] An arc-shaped cover plate 10 is movably installed on one side of the cleaning drum 8. The cleaning drum 8 and the arc-shaped cover plate 10 are movably connected by a rotating shaft 12. Both sides of the cleaning box 9 are provided with sliding grooves that cooperate with the sliding lifting parts 13. Users can place waste plastic products into the cleaning drum 8 by opening the arc-shaped cover plate 10 and closing the arc-shaped cover plate 10 to prevent the waste products in the cleaning drum 8 from breaking and falling out.

[0036] The sliding lifting component 13 includes a T-shaped carriage 26 and a lifting rod 27. The lifting rod 27 is located at the upper middle part of the T-shaped carriage 26. The upper end of the lifting rod 27 is equipped with a docking shaft 28 for use with the cleaning roller 8. By using the sliding lifting component 13, the cleaning roller 8 can be lifted and moved. When the waste plastic is dried after washing, the user starts the lifting rod 27 to lift the cleaning roller 8 by electric lifting, so that the cleaning roller 8 moves upward. The water in the cleaning roller 8 is separated by the columnar mesh plate 11. The cleaning roller 8 is moved as a whole by the T-shaped carriage 26 and moved to the top of the drying tank 7. Then, the lifting rod 27 drives the cleaning roller 8 to move downward, so that the semi-circular drying tank 7 is semi-enclosed and docks with the cleaning roller 8, allowing the cleaning roller 8 to rotate inside the drying tank 7.

[0037] A docking strip 23 is fixedly installed on the lower side of the T-shaped carriage 26, and several sets of electric rollers 24 are movably installed on the lower part of the docking strip 23. Buffer heads 25 are fixedly installed at both ends of the docking strip 23. The rotation of the electric rollers 24 can drive the T-shaped carriage 26 as a whole, so that the T-shaped carriage 26 drives the washing drum 8 to move laterally. After the waste plastic in the washing drum 8 is dried, the lifting rod 27 is used to lift the washing drum 8 again, and the T-shaped carriage 26 moves the washing drum 8 to the upper part of the crushing box 6. The arc-shaped cover 10 is opened to discharge the waste plastic in the crushing box 6 for crushing.

[0038] Two sets of dryers 17 are fixedly installed at the bottom of the drying tank 7. The dryers 17 and the drying tank 7 are connected and fixed through the air guide pipe 16. When the washing drum 8 moves to the inside of the drying tank 7, the dryers 17 and the air guide pipe 16 can be used to heat the inside of the drying tank 7 with hot air. With the rotation of the washing drum 8, the hot air passes through the cylindrical mesh plate 11 to dry the waste plastic inside the washing drum 8.

[0039] The crushing bin 6 includes two sets of crushing rollers 19 and two sets of piercing rollers 21. The two sets of piercing rollers 21 are movably installed on the upper part of the crushing bin 6. The upper end of the crushing bin 6 is provided with a feed inlet. Several sets of spikes 22 are fixedly installed on the outer surface of the piercing rollers 21. The user pours the cleaned and dried waste plastic into the crushing bin 6. By using the rotation of the piercing rollers 21, the spikes 22 can pierce the bottle-shaped plastic products. At the same time, during the rotation of the piercing rollers 21, the bottle-shaped plastic products are flattened, thereby expelling the air inside the bottle-shaped plastic products and preventing them from being squeezed and bursting during the crushing process.

[0040] One end of the two sets of piercing rollers 21 is directly driven by gears, and the other end of the piercing rollers 21 and the crushing rollers 19 are driven by a chain 20 in conjunction with gears. The lower end of the crushing box 6 is provided with an inclined discharge port. The user drives one set of piercing rollers 21 to rotate by a motor. The gear drive structure enables one set of piercing rollers 21 to drive the other set of piercing rollers 21, so that the two sets of piercing rollers 21 rotate synchronously. At the same time, the chain 20 in conjunction with gears enables the two sets of piercing rollers 21 to drive the two sets of crushing rollers 19 respectively, so that the two sets of crushing rollers 19 rotate synchronously.

[0041] A movable push plate 2 is movably installed on the inner side of the fixed base 1. An inclined panel 32 is fixedly installed on the side of the movable push plate 2. Both ends of the movable push plate 2 are fixedly installed with docking slide buckles 31. The upper end of the sliding rack 29 is provided with a fixed tooth head 30. A screen 5 is fixedly installed on the inner side of one end of the crushing box 6. A side rotating cover plate 3 is provided on one end of the fixed base 1.

[0042] This multi-functional waste plastic recycling processing device, by setting up a sliding lifting component 13 and a washing drum 8, allows for flexible adjustment of the washing drum 8's position during use. The washing drum 8 can be used in conjunction with the crushing bin 6, drying tank 7, and washing tank 9. Depending on the processing stage of the waste plastic, the waste plastic inside the washing drum 8 is moved to the corresponding position. By moving the washing drum 8 through the sliding lifting component 13, the crushing bin 6, drying tank 7, and washing tank 9 are connected in series, achieving continuous washing, drying, crushing, and packaging operations. This integrates the entire waste plastic processing flow, effectively improving the processing efficiency of waste plastic. During operation, the washing drum 8 can be raised, lowered, and moved using the sliding lifting component 13. Initially, the washing drum 8 is placed inside the washing tank 9. The motor 14 is started, driving the washing drum 8 to rotate. Water passes through the cylindrical mesh plate 11 and enters the interior of the washing drum 8. During the rotation of the washing drum 8, the waste plastic inside is washed. Simultaneously, the arc-shaped protrusions 15... The design allows the washing drum 8 to collide with the waste plastic during rotation, preventing its accumulation. When drying is required after washing, the user activates the lifting rod 27 to electrically lift the washing drum 8, causing it to move upwards. The cylindrical mesh plate 11 separates the water inside the washing drum 8, and the T-shaped slide 26 moves the washing drum 8 as a whole, placing it above the drying trough 7. The lifting rod 27 then drives the washing drum 8 downwards, causing the semi-circular drying trough 7 to partially enclose the washing drum. 8. The washing drum 8 rotates inside the drying tank 7 to dry the waste plastic. After the waste plastic in the washing drum 8 is dried, the washing drum 8 is lifted again by the lifting rod 27 and moved to the upper part of the crushing box 6 by the T-shaped slide 26. The arc-shaped cover 10 is opened to discharge the waste plastic in the crushing box 6 and crush it. The position of the washing drum 8 can be flexibly adjusted by the lifting and moving operation of the sliding lifting part 13, which facilitates the whole set of waste plastic processing operations and improves its working efficiency.

[0043] By setting up a crushing bin 6, when using this multi-functional waste plastic recycling device, the piercing roller 21 and crushing roller 19 inside the crushing bin 6 can sequentially complete the piercing and crushing operations of waste plastics, preventing the waste plastic bottles from exploding during crushing. During operation, the user pours the cleaned and dried waste plastics into the crushing bin 6. The rotation of the piercing roller 21, in conjunction with the spike 22, pierces the bottle-shaped plastic products. Simultaneously, as the piercing roller 21 rotates, it flattens the bottle-shaped plastic products, thereby expelling the air inside and preventing them from bursting. During the crushing process, a crushing and bursting phenomenon occurs. The user drives a set of piercing rollers 21 to rotate via a motor. The gear drive structure enables one set of piercing rollers 21 to drive another set of piercing rollers 21, making the two sets of piercing rollers 21 rotate synchronously. At the same time, the chain 20, in conjunction with the gear, enables the two sets of piercing rollers 21 to drive the two sets of crushing rollers 19, making the two sets of crushing rollers 19 rotate synchronously. This synchronous rotation of the two sets of piercing rollers 21 and the two sets of crushing rollers 19 improves the stability of the crushing box 6 during use. The setting of piercing rollers 21 and crushing rollers 19 can effectively improve the crushing effect of waste plastics.

[0044] By setting up the drying trough 7 and the telescopic frame 4, when this multi-functional waste plastic recycling processing device is used, the drying trough 7 can work in conjunction with the washing drum 8 to dry the waste plastic inside the washing drum 8. The drying trough 7 adopts a semi-circular structure design, while the outer surface of the washing drum 8 is a cylindrical structure, which allows the drying trough 7 to be locked on the outside of the washing drum 8. When the washing drum 8 moves to the inside of the drying trough 7, the dryer 17 and the air guide pipe 16 can heat the inside of the drying trough 7 with hot air. With the rotation of the washing drum 8, the hot air passes through the cylindrical mesh plate 11 to dry the waste plastic inside the washing drum 8, allowing the hot air to fully enter the interior of the washing drum 8, effectively improving the drying effect of the waste plastic inside the washing drum 8. Secondly, the telescopic frame 4 uses the fixing teeth 30 of the sliding rack 29 to fix packaging bags of different sizes, which facilitates the bagging of the crushed plastic particles after the waste plastic crushing operation is completed in the crushing bin 6.
