Description

Technical Field

[0001] This invention relates to the field of comprehensive recycling of solid waste, and in particular to a system and method for recycling and granulating carbon-based packaging box waste. Background Technology

[0002] Carbon-based packaging box waste consists of waste plastic scraps, scrapped boxes, and broken materials generated after carbon-based packaging boxes have been used and scrapped. These materials can be processed through crushing, water control, hot-melt extrusion, and cooling pelletizing to make black carbon-based recycled plastic pellets, which can then be used for production, thus realizing the reuse of solid waste. In the recycling of carbon-based packaging box waste, crushing is a crucial step. Current technologies mostly utilize the gravity of the waste material itself, employing a crushing mechanism followed by screening. Unscreened material is then sent to another crushing mechanism for further processing. However, due to the varying shapes of the carbon-based packaging box waste, the effectiveness of the first crushing process is unreliable. The amount of unscreened waste material after the first crushing is uncertain, leading to inconsistent discharge flow rates. This disrupts the feeding rhythm of subsequent screening, water control, and hot-melting processes, making it difficult to control the material's moisture content and melting / plasticizing effect. This directly results in uneven extrusion thickness, large deviations in pellet size, and unstable quality of the finished pellets.

[0003] Therefore, it is necessary to propose a carbon-based packaging waste recycling and granulation system and method to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a carbon-based packaging waste recycling and granulation system and method, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A carbon-based packaging box waste recycling and granulation system comprises a carbon-based packaging box waste crushing mechanism, a water control mechanism, a hot melt machine, an extrusion molding mechanism, a cooling mechanism, and a cutting mechanism. The carbon-based packaging box waste crushing mechanism is used to crush carbon-based packaging box waste. The water control mechanism is used to remove moisture adhering to the surface of the crushed carbon-based packaging box waste; The hot melt machine is used for segmented constant temperature heating of dehydrated and cleaned carbon-based packaging box waste fragments, gradually softening and melting the solid plastic fragments into a high-temperature viscous molten colloid. The extrusion molding mechanism is used to extrude completely molten carbon-based plastic colloid into a continuous and straight plastic strip with uniform thickness through a strip-shaped discharge hole customized in the die head. The cooling mechanism is used to air-cool or water-cool the plastic strip, allowing the high-temperature strip to cool and solidify rapidly. The cutting mechanism is used to cut the cooled and solidified plastic strips into uniform cylindrical plastic granules to complete the recycling granulation process. The carbon-based packaging box waste crushing mechanism includes a crushing box with a feed inlet at the top and a discharge outlet at one end near the bottom. Two crushing gears are rotatably connected to the inner wall of the crushing box near the feed inlet, meshing with each other. A first motor is fixedly connected to the outer surface of the crushing box, and a first transmission column is fixedly connected to the output end of the first motor. The end of the first transmission column away from the first motor is fixedly connected to one of the crushing gears. A second transmission column is rotatably connected to the surface of the crushing box below the two crushing gears. Sprockets are fixedly connected to the surfaces of both the first and second transmission columns, and the two sprockets are driven by a chain. A screen plate is slidably connected to the inner wall of the crushing box between the crushing gears and the second transmission column, and the screen plate is fitted to the second transmission column. The inner wall of the crushing box has through holes at both ends of the screen plate. A U-shaped plate is slidably connected to the surface of the crushing box next to the through holes. A rotating plate is mounted on the surface of the U-shaped plate by a torsion spring. An L-shaped column is rotatably connected to the lower surface of the rotating plate. A connecting column is rotatably connected to the end of the L-shaped column away from the rotating plate. A rotating sleeve is slidably connected to the surface of the connecting column. Movable rods are slidably connected to the ends of the two rotating sleeves away from the L-shaped column. Lifting plates are rotatably connected to the ends of the two movable rods away from the rotating sleeves. The lifting plate is slidably connected to the crushing box. A movable block is slidably connected to the upper surface of the lifting plate. An adjusting column is rotatably connected to the surface of the movable block. A third transmission column is rotatably connected to the end of the adjusting column away from the movable block. A reducer is installed at the end of the third transmission column away from the adjusting column. A reducer is installed at the end of the second transmission column away from the sprocket. A positioning column is rotatably connected to the middle of the surface of the rotating sleeve. The ends of the two positioning columns away from the rotating sleeve are fixedly connected to the crushing box. A rotating column is fitted onto the surface of the L-shaped column. The rotating column is connected to the crushing box by a torsion spring. A receiving box is slidably connected to the end of the two rotating columns away from the L-shaped column. A fixing block is fitted onto two sides of the receiving box. Both fixing blocks are fixedly connected to the inner wall of the crushing box.

[0006] Preferably, two sides of the sieve plate are rotatably connected to wheels, and cams are symmetrically fixedly connected to the surface of the second transmission column, with the wheels and cams being fitted together.

[0007] Preferably, the surface of the feed inlet is symmetrically provided with first inclined grooves.

[0008] Preferably, a vertical plate is fixedly connected to the lower surface of the U-shaped plate, and both vertical plates are slidably connected to the crushing box.

[0009] Preferably, a friction plate is fixedly connected to the surface of the fixing block, and both friction plates are installed in conjunction with the receiving box.

[0010] Preferably, the lifting plate is symmetrically fixedly connected to connecting sleeves on the surface away from the rotating sleeve, and both connecting sleeves are slidably connected to the crushing box.

[0011] Preferably, a limiting groove is formed on the upper surface of the lifting plate, and the movable block is slidably connected to the limiting groove.

[0012] A method for recycling and granulating carbon-based packaging box waste includes the carbon-based packaging box waste recycling and granulation system described above, and the method includes the following steps; S1: The carbon-based packaging waste is placed on the surface of the first inclined chute. The first motor drives the first transmission column to rotate. The crushing gear rotates with the first gear. Since the two crushing gears are meshed, they are adjusted to rotate simultaneously and in opposite directions to crush the carbon-based packaging waste. The second transmission column rotates with the first transmission column. The cam and the wheel cooperate to continuously drive the screen plate to move up and down during the adjustment of the second transmission column, separating the crushed carbon-based packaging waste. The incompletely crushed carbon-based packaging waste slides down the surface of the screen plate and is placed on the surface of the rotating plate. The speed is reduced by a reducer. The third transmission column rotates slower than the second transmission column. The adjusting column rotates with the third transmission column, which drives the movable block to rotate. The movable block and the limiting groove move relative to each other. The lifting plate is adjusted and moved. Due to the setting of the positioning column, the rotating sleeve is adjusted and rotated with the lifting plate. The movable rod and the rotating sleeve move relative to each other. The connecting column and the rotating sleeve move relative to each other. The rotating plate and the U-shaped plate are both adjusted and moved upward. Then the U-shaped plate is adjusted and moved to the highest position. As the adjusting column continues to be adjusted and rotated, the rotating plate is adjusted and rotated until the movable block is adjusted to the lowest position. The rotating plate stops being adjusted and rotated. The carbon-based packaging box waste that has been crushed on the surface of the rotating plate slides to the feed inlet and is crushed again. This cycle ensures that the carbon-based packaging box waste is fully crushed and processed. As the screen plate separates the waste carbon-based packaging boxes, the crushed waste accumulates on the surface of the receiving box. When a certain amount is reached, under the action of gravity, as the rotating plate and U-shaped plate are adjusted to move upward, the receiving box can overcome the elastic force of the torsion spring set between the rotating column and the crushing box and move downward until the receiving box is connected to the discharge port, so that the crushed waste carbon-based packaging boxes can be discharged, thus achieving quantitative discharge. When the adjusting column is adjusted and rotated back to its initial position, that is, during the process of the movable block moving from a low position to a high position, the rotating plate is adjusted to rotate in the opposite direction. The L-shaped column, the rotating plate, and the U-shaped plate are all adjusted to move downward. The L-shaped column contacts the rotating column, the rotating column is adjusted to rotate, and the receiving box is adjusted to move upward, so that the receiving box is reset. S2: The crushed material enters the water control mechanism, which uses the dual action of high-speed centrifugal drying and filtration to remove the water or surface moisture adhering to the waste material. Simultaneously, it filters and screens out sand, light paper scraps, and fine carbon residue impurities mixed in the crushed material, reducing the material moisture content to the hot melt standard, preventing bubbling, smoke, and hollow particles during high-temperature hot melt, and ensuring uniform texture of subsequent melting. S3: The dehydrated and cleaned carbon-based plastic scraps are fed into the hot melt machine at a uniform speed and heated at a constant temperature in stages. The solid plastic scraps are gradually softened and melted into a high-temperature viscous molten colloid. The molten waste is continuously compacted by using a spiral push and stirring method to remove residual air and trace amounts of moisture from the material, allowing the carbon-based filler and plastic matrix to fully integrate. S4: The fully molten carbon-based plastic colloid is pushed into the extrusion die head under high pressure by the spiral thrust of the hot melt machine. Through the customized strip-shaped discharge hole of the die head, the scattered molten colloid is extruded into plastic strips of uniform thickness and continuous straightness, shaping the basic shape of the granules and ensuring that the output thickness is consistent. S5: The freshly extruded high-temperature plastic strip is extremely hot, soft and easily deformed. It is immediately sent to the cooling mechanism and rapidly cooled down by water or air cooling to allow the high-temperature strip to cool and solidify quickly. After hardening, the plastic strip meets the hardness standard, does not stick, does not deform, and has the hardness to be cut. S6: The continuous plastic strip that has been cooled and hardened is conveyed at a constant speed to the cutting station. It is cut to a fixed length by a high-speed rotating cutter and precisely cut according to the set specifications. It is then cut into uniform cylindrical plastic granules, and finally qualified carbon-based recycled plastic granules are produced, completing the entire recycling granulation process.

[0013] Compared with the prior art, the present invention provides a carbon-based packaging box waste recycling and granulation system and method, which has the following beneficial effects: 1. This carbon-based packaging box waste recycling and granulation system, through its carbon-based packaging box waste crushing mechanism, can temporarily collect crushed carbon-based packaging box waste that cannot be screened by the sieve plate, and then place it back into the feed inlet for further crushing. As the crushed carbon-based packaging box waste accumulates on the surface of the receiving box, under its own gravity, the receiving box overcomes the friction between itself and the friction plate and the elastic force of the torsion spring between the rotating column and the crushing box, and moves downward. The contact area between the receiving box and the friction plate gradually decreases, and the friction gradually decreases until the receiving box connects with the discharge port, thereby quantitatively discharging the crushed carbon-based packaging box waste. In other words, regardless of the feeding situation, the crushing and discharge flow rate is stable, thus ensuring the processing effect of subsequent steps.

[0014] 2. In this carbon-based packaging waste recycling and granulation system, as the U-shaped plate and rotating plate are adjusted and moved upward together, the vertical plate blocks the through holes. The crushed carbon-based packaging waste has enough time to remain on the surface of the screen plate. The rotation of the second drive column can stably drive the two cams to rotate, so that the screen plate can move up and down continuously. The crushed carbon-based packaging waste on the screen plate surface can be quickly screened, ensuring the screening effect. Waste that meets the screening standards will not be crushed again. Qualified materials are diverted and separated in advance, and only large pieces of materials that do not meet the standards are returned for further crushing. This effectively reduces the working pressure of the two-stage crushing mechanism, reduces equipment idling and overload operation, reduces motor power consumption, and extends the service life of the equipment.

[0017] 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.

[0018] Please see Figures 1 to 8 A carbon-based packaging box waste recycling and granulation system comprises a carbon-based packaging box waste crushing mechanism 1, a water control mechanism 2, a hot melt machine 3, an extrusion molding mechanism 4, a cooling mechanism 5, and a cutting mechanism 6. The carbon-based packaging box waste crushing mechanism 1 is used to crush carbon-based packaging box waste. The water control mechanism 2 is used to remove moisture adhering to the surface of the crushed carbon-based packaging box waste; The hot melt machine 3 is used for segmented constant temperature heating of dehydrated and cleaned carbon-based packaging box waste fragments, gradually softening and melting the solid plastic fragments into a high-temperature viscous molten colloid; The extrusion molding mechanism 4 is used for fully molten carbon-based plastic colloids. Through the die head with a customized strip-shaped discharge hole, the scattered molten colloids are extruded into plastic strips of uniform thickness and continuous straightness. Cooling mechanism 5 is used to air-cool or water-cool the plastic strip, allowing the high-temperature strip to cool down and solidify quickly. The cutting mechanism is used to cut the cooled and solidified plastic strips into uniform cylindrical plastic granules, thus completing the recycling granulation process. The carbon-based packaging box waste crushing mechanism 1 includes a crushing box 11, with a feed inlet 12 at the top and a discharge outlet 13 at one end near the bottom of the crushing box 11. Two crushing gears 14 are rotatably connected to the inner wall of the crushing box 11 near the feed inlet 12, meshing with each other. A first motor 15 is fixedly connected to the outer surface of the crushing box 11, and a first transmission column 16 is fixedly connected to the output end of the first motor 15. One end of the first transmission column 16 away from the first motor 15 is fixedly connected to one of the crushing gears 14. A second transmission column 17 is rotatably connected to the surface of the crushing box 11 below the two crushing gears 14. Both the first and second transmission columns 16 and 17 are fixedly connected to sprockets 18, which are driven by a chain. A screen plate 19 is slidably connected to the inner wall of the crushing box 11 between the crushing gears 14 and the second transmission column 17, and the screen plate 19 is fitted with the second transmission column 17. The inner wall of the crushing box 11 has through holes 110 at both ends of the screen plate 19. A U-shaped plate 111 is slidably connected to the surface of the crushing box 11 next to the through holes 110. A rotating plate 112 is mounted on the surface of the U-shaped plate 111 via a torsion spring. An L-shaped column 113 is rotatably connected to the lower surface of the rotating plate 112. A connecting column 114 is rotatably connected to the end of the L-shaped column 113 away from the rotating plate 112. A rotating sleeve 115 is slidably connected to the surface of the connecting column 114. Movable rods 116 are slidably connected to the ends of the two rotating sleeves 115 away from the L-shaped columns 113. A lifting plate 115 is rotatably connected to the ends of the two movable rods 116 away from the rotating sleeves 115. 17. The lifting plate 117 is slidably connected to the crushing box 11. A movable block 118 is slidably connected to the upper surface of the lifting plate 117. An adjusting column 119 is rotatably connected to the surface of the movable block 118. A third transmission column 120 is rotatably connected to the end of the adjusting column 119 away from the movable block 118. A reducer 121 is installed at the end of the third transmission column 120 away from the adjusting column 119. The end of the second transmission column 17 away from the sprocket 18 is installed with the reducer 121. A positioning column 122 is rotatably connected to the middle of the surface of the rotating sleeve 115. The ends of the two positioning columns 122 away from the rotating sleeve 115 are fixedly connected to the crushing box 11. A rotating column 123 is fitted onto the surface of the L-shaped column 113. The rotating column 123 is connected to the crushing box 11 by a torsion spring. A receiving box 124 is slidably connected to the end of the two rotating columns 123 away from the L-shaped column 113. A fixing block 125 is fitted onto two sides of the receiving box 124. Both fixing blocks 125 are fixedly connected to the inner wall of the crushing box 11. It should be noted that the reducer 121 is an existing planetary gear reducer.

[0019] Two of the sides of the sieve plate 19 are rotatably connected to a wheel 126, and a cam 127 is symmetrically fixedly connected to the surface of the second transmission column 17. The wheel 126 and the cam 127 are fitted together. It should be noted that the two cams 127 can rotate along with the second transmission column 17. The cams 127 are in contact with the wheel 126. The rotation of the cams 127 can stably drive the wheel 126 to rotate, thereby driving the screen plate 19 and the wheel 126 to move up and down continuously.

[0020] The surface of the feed inlet 12 is symmetrically provided with first inclined grooves 128; It should be noted that the first inclined chute 128 is designed to facilitate the sliding of carbon-based packaging waste into the crushing box 11, making feeding easier.

[0021] A vertical plate 129 is fixedly connected to the lower surface of the U-shaped plate 111, and both vertical plates 129 are slidably connected to the crushing box 11. It should be noted that during the upward movement of the U-shaped plate 111 and the rotating plate 112, the through hole 110 is blocked by the vertical plate 129. The crushed carbon-based packaging waste has enough time to remain on the surface of the screen plate 19. The rotation of the second transmission column 17 can stably drive the two cams 127 to rotate, so that the screen plate 19 can move up and down continuously. The crushed carbon-based packaging waste on the surface of the screen plate 19 can be quickly screened, and the screening effect is guaranteed. Waste that meets the screening standards will not be crushed again. Qualified materials are diverted and separated in advance, and only large pieces of unqualified materials are returned for further crushing. This effectively reduces the working pressure of the two-stage crushing mechanism, reduces equipment idling and overload operation, reduces motor power consumption, and extends the service life of the equipment.

[0022] A friction plate 130 is fixedly connected to the surface of the fixing block 125, and both friction plates 130 are installed in conjunction with the receiving box 124. It should be noted that as the carbon-based packaging waste accumulated on the surface of the receiving box 124 after crushing, under its own gravity, the receiving box 124 overcomes the friction between itself and the friction plate 130 and the elastic force of the torsion spring between the rotating column 123 and the crushing box 11, and moves downward. The contact area between the receiving box 124 and the friction plate 130 gradually decreases, and the friction gradually decreases until the receiving box 124 is connected to the discharge port 13, thereby quantitatively discharging the crushed carbon-based packaging waste. In other words, regardless of the feeding situation, the crushing discharge flow rate is stable, thus ensuring the processing effect of subsequent steps.

[0023] The lifting plate 117 has connecting sleeves symmetrically fixed to the surface away from the rotating sleeve 115, and both connecting sleeves are slidably connected to the crushing box 11. It should be noted that the connecting sleeve is L-shaped. The connecting sleeve is designed to connect and limit the movement of the lifting plate 117, ensuring the stability of the lifting plate 117 during the adjustment and movement process.

[0024] A limiting groove 131 is provided on the upper surface of the lifting plate 117, and the movable block 118 is slidably connected to the limiting groove 131. It should be noted that the limiting groove 131 serves as a connection and can limit the movement of the movable block 118, so that the movable block 118 can be adjusted and rotated together with the adjusting column 119, which can stably drive the lifting plate 117 to move up and down, and relative movement occurs between the movable block 118 and the limiting groove 131.

[0025] A method for recycling and granulating carbon-based packaging box waste includes the aforementioned carbon-based packaging box waste recycling and granulation system, and the method includes the following steps; S1: The carbon-based packaging box waste is placed on the surface of the first inclined groove 128. The first motor 15 drives the first transmission column 16 to rotate. The crushing gear 14 rotates with the first gear. Since the two crushing gears 14 mesh, the two crushing gears 14 are adjusted to rotate simultaneously, and the two rotate in opposite directions to crush the carbon-based packaging box waste. The chain sprocket 18 drives the second transmission column 17 to rotate with the first transmission column 16. The cam 127 cooperates with the wheel 126. During the adjustment and rotation of the second transmission column 17, the screen plate 19 can be continuously driven to move up and down to separate the crushed carbon-based packaging box waste. The carbon-based packaging box waste that is not completely crushed slides down the surface of the screen plate 19 and is placed on the surface of the rotating plate 112. The speed is reduced by the reducer 121. The third transmission column 120 rotates slower than the second transmission column 17. The adjusting column 119 rotates together with the third transmission column 120, thereby driving the movable block 118 to rotate. The movable block 118 and the limiting groove 131 move relative to each other, and the lifting plate 117 is adjusted and moved. Due to the setting of the positioning column 122, the rotating sleeve 115 is adjusted and rotated along with the lifting plate 117. During the rotation, the movable rod 116 and the rotating sleeve 115 move relative to each other. The connecting column 114 and the rotating sleeve... Relative movement occurs between 115, and both the rotating plate 112 and the U-shaped plate 111 are adjusted to move upward. Then, the U-shaped plate 111 is adjusted to move to the highest position. As the adjusting column 119 continues to be adjusted and rotated, the rotating plate 112 is adjusted and rotated until the movable block 118 is adjusted to the lowest position. The rotating plate 112 stops being adjusted and rotated, and the carbon-based packaging box waste that has been crushed on the surface of the rotating plate 112 slides down to the feed inlet 12 for crushing again. This cycle ensures that the carbon-based packaging box waste can be fully crushed. As the screen plate 19 screens, the crushed carbon-based packaging box waste accumulates on the surface of the receiving box 124. When a certain amount is reached, under the action of gravity, as the rotating plate 112 and U-shaped plate 111 are adjusted to move upward, the receiving box 124 can overcome the elastic force of the torsion spring set between the rotating column 123 and the crushing box 11 and move downward until the receiving box 124 is connected to the discharge port 13 to discharge the crushed carbon-based packaging box waste, thus achieving quantitative discharge. When the adjusting column 119 is adjusted and rotated back to its initial position, that is, during the process of the movable block 118 moving from a low position to a high position, the rotating plate 112 is adjusted to rotate in the opposite direction. The L-shaped column 113, the rotating plate 112 and the U-shaped plate 111 are all adjusted to move downward. The L-shaped column 113 contacts the rotating column 123. The rotating column 123 is adjusted to rotate, and the receiving box 124 is adjusted to move upward, so that the receiving box 124 is reset. S2: The crushed material enters the water control mechanism 2, which uses the dual action of centrifugal high-speed spin drying and draining filtration to remove the water or surface moisture adhering to the surface of the waste material. Simultaneously, it filters and screens out the sand, light paper scraps, and fine carbon residue impurities mixed in the crushed material, reducing the material moisture content to the hot melt standard, preventing bubbling, smoke, and hollow particles during high-temperature hot melt, and ensuring uniform texture of subsequent melting. S3: The dehydrated and cleaned carbon-based plastic scraps are fed into the hot melt machine 3 at a uniform speed and heated in sections at a constant temperature. The solid plastic scraps are gradually softened and melted into a high-temperature viscous molten colloid. The molten waste is continuously compacted by using a spiral push and stirring method to remove residual air and trace amounts of water vapor inside the material, so that the carbon-based filler and plastic matrix can be fully integrated. S4: The fully molten carbon-based plastic colloid is pushed into the extrusion die head under high pressure by the spiral thrust of the hot melt machine. Through the customized strip-shaped discharge hole of the die head, the scattered molten colloid is extruded into plastic strips of uniform thickness and continuous straightness, shaping the basic shape of the granules and ensuring that the output thickness is consistent. S5: The freshly extruded high-temperature plastic strip is extremely hot, soft and easily deformed. It is immediately sent to the cooling mechanism 5 and rapidly cooled down by water or air cooling, so that the high-temperature strip can be quickly cooled, solidified and shaped. After hardening, the plastic strip has the required hardness, does not stick, does not deform, and has the hardness to be cut. S6: The continuous plastic strip that has been cooled and hardened is conveyed at a constant speed to the cutting station. It is cut to a fixed length by a high-speed rotating cutter and precisely cut according to the set specifications. It is then cut into uniform cylindrical plastic granules, and finally qualified carbon-based recycled plastic granules are produced, completing the entire recycling granulation process.

8. A method for recycling and granulating carbon-based packaging box waste, comprising the carbon-based packaging box waste recycling and granulation system as described in any one of claims 1-7, characterized in that, The method for recycling and granulating carbon-based packaging box waste includes the following steps; S1: The carbon-based packaging box waste is placed on the surface of the first inclined groove (128). The first motor (15) drives the first transmission column (16) to rotate. The crushing gear (14) rotates with the first gear. Since the two crushing gears (14) mesh, the two crushing gears (14) are adjusted to rotate at the same time, and the two rotate in opposite directions to crush the carbon-based packaging box waste. The chain sprocket (18) drives the second transmission column (17) to rotate with the first transmission column (16). The cam (127) cooperates with the wheel (126). During the process of the second transmission column (17) being adjusted to rotate, it can continuously drive the screen plate (19) to move up and down to separate the crushed carbon-based packaging box waste. The carbon-based packaging box waste that is not completely crushed slides down along the surface of the screen plate (19) and is placed on the surface of the rotating plate (112). The speed is reduced by the reducer (121). The third transmission column (120) rotates slower than the second transmission column (17). The adjusting column (119) rotates together with the third transmission column (120), thereby driving the movable block (118) to rotate. The movable block (118) and the limiting groove (131) move relative to each other. The lifting plate (117) is adjusted and moved. Due to the setting of the positioning column (122), the rotating sleeve (115) is adjusted and rotated along with the lifting plate (117). During the rotation, the movable rod (116) and the rotating sleeve (115) move relative to each other. The connecting column (114) moves. Relative movement occurs between the rotating sleeve (115) and the rotating plate (112) and the U-shaped plate (111). Both are adjusted to move upward. Then the U-shaped plate (111) is adjusted to move to the highest position. As the adjusting column (119) continues to be adjusted and rotated, the rotating plate (112) is adjusted and rotated until the movable block (118) is adjusted to the lowest position. The rotating plate (112) stops being adjusted and rotated. The carbon-based packaging box waste that has been crushed on the surface of the rotating plate (112) slides down to the feed inlet (12) and is crushed again. This cycle ensures that the carbon-based packaging box waste can be fully crushed. As the screen plate (19) screens, the crushed carbon-based packaging box waste accumulates on the surface of the receiving box (124). When it reaches a certain amount, under the action of gravity, as the rotating plate (112) and U-shaped plate (111) are adjusted to move upward, the receiving box (124) can overcome the elastic force of the torsion spring set between the rotating column (123) and the crushing box (11) and move downward until the receiving box (124) is connected to the discharge port (13) to discharge the crushed carbon-based packaging box waste, thus achieving quantitative discharge. When the adjusting column (119) is adjusted and rotated back to its initial position, that is, during the process of the movable block (118) moving from a low position to a high position, the rotating plate (112) is adjusted to rotate in the opposite direction, and the L-shaped column (113), the rotating plate (112) and the U-shaped plate (111) are all adjusted to move downward. The L-shaped column (113) contacts the rotating column (123), the rotating column (123) is adjusted to rotate, and the receiving box (124) is adjusted to move upward, so that the receiving box (124) is reset. S2: The crushed material enters the water control mechanism (2), and the water or surface moisture adhering to the surface of the waste material is removed by the double action of centrifugal high-speed spin drying and water filtration. Simultaneously, the sand, light paper scraps, and fine carbon residue impurities mixed in the crushed material are filtered and screened to reduce the moisture content of the material to the hot melt standard, and prevent bubbling, smoke and hollow particles during high-temperature hot melt, so as to ensure that the subsequent melting texture is uniform. S3: The dehydrated and cleaned carbon-based plastic scraps are fed into the hot melt machine (3) at a uniform speed and heated in sections at a constant temperature. The solid plastic scraps are gradually softened and melted, and transformed into a high-temperature viscous molten colloid. The molten waste is continuously compacted by using a spiral push and stirring method to discharge the residual air and trace amount of water vapor inside the material, so that the carbon-based filler and plastic matrix can be fully integrated. S4: The completely molten carbon-based plastic colloid is pushed into the extrusion die head under high pressure by the spiral thrust of the hot melt machine (3). The scattered molten colloid is extruded into a plastic strip with uniform thickness and continuous straightness through the strip-shaped discharge hole of the die head, and the basic shape of the granules is shaped to ensure that the thickness of the discharge is consistent. S5: The extruded high-temperature plastic strip is extremely hot and soft and easily deformed. It is immediately sent to the cooling mechanism (5) and water or air cooling is used to quickly cool it down so that the high-temperature strip can be quickly cooled, solidified and shaped. After hardening, the plastic strip has the required hardness, does not stick, does not deform, and has the hardness to be cut. S6: The continuous plastic strip that has been cooled and hardened is conveyed at a constant speed to the cutting station. It is cut to a fixed length by a high-speed rotating cutter and precisely cut according to the set specifications. It is then cut into uniform cylindrical plastic granules, and finally qualified carbon-based recycled plastic granules are produced, completing the entire recycling granulation process.
