Description

A waste recycling device for cardboard box manufacturing Technical Field

[0001] This invention relates to the field of waste recycling technology, specifically to a waste recycling device for cardboard box manufacturing. Background Technology

[0002] Cardboard boxes, as a primary packaging material, are widely used in commodity transportation and warehousing. With the booming development of e-commerce and the continuous expansion of the logistics industry, the consumption of cardboard boxes has exploded, resulting in a sharp increase in the amount of waste cardboard boxes. According to industry statistics, express delivery packaging alone generates millions of tons of waste cardboard boxes annually. How to efficiently and environmentally recycle these waste paper resources has become a critical issue that the packaging industry and the environmental protection sector urgently need to address.

[0003] Existing cardboard waste recycling processes, such as hydraulic pulping, deinking, and drying, suffer from high water consumption, difficult wastewater treatment, high drying energy consumption, and can lead to severe keratinization and irreversible curling and twisting of fibers, shortening fiber length and reducing bonding strength. Recycled cardboard boxes often need to incorporate a large amount of virgin fiber or increase the basis weight to meet strength requirements. Moreover, starch glue, polyvinyl acetate adhesive, and printing inks are widely used in cardboard box production. Some of these substances are detached during traditional hydraulic pulping, forming sticky impurities. These adhesives are very easy to deposit on the surface of papermaking wires, pressure rollers, and drying cylinders, causing production obstacles. At the same time, they remain in the finished paper, forming defects and weak areas. Although some technologies have attempted to alleviate the adhesive problem by pre-treating with alkaline solutions or adding chemical dispersants, the effects are limited and increase chemical consumption and the burden of subsequent wastewater treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a waste recycling device for cardboard box manufacturing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A base is included, a disintegration chamber is connected to the top of the base, multiple sets of metal rollers are rotatably arranged between the inner walls of the disintegration chamber, multiple sets of elastic components are connected to both sides of the disintegration chamber, auxiliary components are connected between the multiple sets of metal rollers, a whistle shell is connected to the other end of the disintegration chamber, a drive motor is connected to one side of the whistle shell, the output end of the drive motor extends into the whistle shell and is connected to a feeding auger, a spray unit is connected to the top of the whistle shell, a forming component is connected to the other end of the spray unit, a reinforcing member is connected between the forming component and the spray unit, a frequency conversion ultrasonic generator is connected to the surface of the reinforcing member, a reinforcing ring is connected to one side of the inner wall of the forming component, an anti-interference motor is connected to one side of the reinforcing ring, the output end of the anti-interference motor passes through the reinforcing ring and is connected to a drying component, and a sealing support frame is connected between one end of the drying component and the forming component.

A suction pipe is connected to the input end of the water pump, and a discharge pipe is connected to the output end. Multiple atomizing nozzles are connected to one side of the discharge pipe, and the atomizing nozzles are fixedly mounted on the top of the whistle housing.

[0009] Preferably, the molding component includes an insulating shell, a molding hollow cylinder is rotatably disposed inside the insulating shell, a permanent magnet is connected to the surface of the molding hollow cylinder, an electromagnetic coil is connected to the surface of the insulating shell, a plurality of micro-holes are opened inside the insulating shell, and a quick-connect pipe is rotatably disposed on one side of the molding hollow cylinder.

[0013] Preferably, the dissociation chamber is arranged in a vortex shape, and both the inner surface and the surface of the metal roller are provided with an insulating ceramic coating.

[0014] In summary, the beneficial effects of this invention are as follows: This application uses a high-voltage electric field to break the bond between adhesives and fibers, combined with targeted degradation by bio-enzymes and ultrasonic-assisted separation, forming a multi-stage adhesive treatment system. This is more environmentally friendly than simply using chemicals and can more effectively remove adhesives, reducing their deposition on subsequent papermaking equipment and damage to the quality of finished paper.

The vortex dissociation chamber design extends the material handling path and ensures the treatment effect. The application of the insulating ceramic coating is both wear-resistant and ensures the stable operation of the high-voltage electric field. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0018] Please refer to Figures 1-8. This invention provides a technical solution: It includes a base 1, with a disintegration chamber 2 connected to the top of the base 1. Multiple sets of metal rollers 3 are rotatably arranged between the inner walls of the disintegration chamber 2, and high-frequency, high-voltage alternating current is connected to the metal rollers 3 as high-voltage electrodes. These electrodes cooperate with the tooth tips 301 to achieve a tip discharge effect, and also physically tear and loosen the waste material. The disintegration chamber 2 serves as a grounding electrode. A ring-shaped discharge gap is formed between the tooth tips 301 on the outer surface of the metal rollers 3 and the inner wall of the disintegration chamber 2. After the waste material enters the disintegration chamber 2, it falls into this gap. As the metal rollers 3 rotate, the waste material is forcibly carried into the high-voltage electric field region. Multiple sets of elastic components 4 are connected to both sides of the disintegration chamber 2, and auxiliary components 6 are connected between the multiple sets of metal rollers 3. A whistle shell 8 is connected to the other end of the disintegration chamber 2. A drive motor 9 is connected to one side of the whistle housing 8. The output end of the drive motor 9 extends into the whistle housing 8 and is connected to a feeding auger 10. A spray unit 11 is connected to the top of the whistle housing 8. A forming component 12 is connected to the other end of the spray unit 11. A reinforcing member 13 is connected between the forming component 12 and the spray unit 11. A variable frequency ultrasonic generator 131 is connected to the surface of the reinforcing member 13. The cavitation effect of the ultrasonic waves helps to further disperse the fibers and separate some of the adhesive from the fibers. A reinforcing ring 222 is connected to one side of the inner wall of the forming component 12. An anti-interference motor 16 is connected to one side of the reinforcing ring 222. The output end of the anti-interference motor 16 passes through the reinforcing ring 222 and is connected to a drying component 14. A sealing support frame 15 is connected between one end of the drying component 14 and the forming component 12.

[0019] Referring to Figure 5, the elastic component 4 includes a directional frame 41 fixedly mounted on both sides of the disintegration chamber 2. A movable traction member 42 is slidably mounted on the inner side of the directional frame 41. A traction spring 43 is connected between one side of the movable traction member 42 and the inner side of the directional frame 41. The two ends of the metal roller 3 are rotatably connected to the movable traction member 42, and a hollow motor 5 is connected to one end of the metal roller 3. Tooth tips 301 are connected to the surface of the metal roller 3. As can be seen from Figure 4, a strip-shaped hole is opened on the surface of the disintegration chamber 2 corresponding to the metal roller 3. The metal roller 3 can move along the strip-shaped hole. While moving, the metal roller 3 will move slightly along the directional frame 41 with the movable traction member 42. The elastic force of the traction spring 43 achieves floating compression, ensuring the compression of the metal roller 3 and the cardboard.

[0020] Referring to Figure 5, the auxiliary component 6 includes a connecting ring 61 that is rotatably fitted at one end of the metal roller 3. Each connecting ring 61 at one end of the metal roller 3 is connected to a spring piece 62. Each spring piece 62 is connected to a connecting ring 63 at the end that is close to each other. A squeeze roller 64 is rotatably mounted on one side of the connecting ring 63. When the metal roller 3 moves back and forth, the connecting ring 61 and the spring piece 62 pull the connecting ring 63, thereby driving the squeeze roller 64 to move. Under the action of the spring piece 62, the squeeze roller 64 always adheres to the surface of the paper entering the release chamber 2, so that the paper is pressed against the inner wall of the release chamber 2. At the same time, it is convenient for the paper to enter between the metal roller 3 and the release chamber 2 and be driven by the tooth tip 301, which plays an auxiliary squeezing role and ensures the stable operation of the paper.

[0021] Referring to Figure 7, the spraying unit 11 includes a fixed platform 111 fixedly mounted on the top of the whistle housing 8. A water pump 112 is connected to the top of the fixed platform 111. A material extraction pipe 113 is connected to the input end of the water pump 112. The other end of the material extraction pipe 113 is connected to an external agent source, which is a compound biological enzyme preparation containing cellulase, hemicellulase and laccase. A discharge pipe 114 is connected to the output end of the material extraction pipe 114. Multiple atomizing nozzles 115 are connected to one side of the discharge pipe 114. The atomizing nozzles 115 are fixedly mounted on the top of the whistle housing 8. After the waste paper is separated by the separation chamber 2 and enters the whistle housing 8, the water pump 122 extracts the compound biological enzyme preparation through the material extraction pipe 113 and discharges it through the discharge pipe 114 to the atomizing nozzles 115 and sprays it evenly on the surface of the paper.

[0022] Referring to Figures 7 and 8, the molding assembly 12 includes an insulating shell 121, a molding hollow cylinder 122 rotatably disposed inside the insulating shell 121, a permanent magnet 123 connected to the surface of the molding hollow cylinder 122, an electromagnetic coil 124 connected to the surface of the insulating shell 121, and multiple micro-holes opened inside the insulating shell 121. Through the interaction between the electromagnetic coil 124 and the permanent magnet 123, the molding hollow cylinder 122 can be driven to rotate. The multiple micro-holes inside the insulating shell 121 are used to drain excess water from the slurry. A quick-connect pipe is rotatably disposed on one side of the molding hollow cylinder 122, and an external vacuum pump is connected to the outside of the quick-connect pipe to ensure that a negative pressure is formed inside the molding hollow cylinder 122.

[0023] Referring to Figures 7 and 8, the drying assembly 14 includes a spacer cylinder 141. A partition 142 is connected between the inner walls of the spacer cylinder 141. A fixing frame 143 is connected to both sides of the partition 142. A microwave generating assembly 144 is connected to one side of each fixing frame 143. The microwave generating assembly 144 can emit microwaves to uniformly heat the wet blank on the forming hollow cylinder 122 from the inside out, achieving efficient drying. A material gathering and stirring plate 145 is connected to one end of the spacer cylinder 141. During rotation, the material gathering and stirring plate 145 can better push the material into the gap between the forming assembly 12 and the drying assembly 14, and can also prevent material accumulation. In order to monitor the drying process in real time, a temperature and humidity sensor (not shown in the figure) is connected to the surface of the spacer cylinder 141 for feedback and adjustment of the power of the microwave generating assembly 144.

[0024] Referring to Figure 7, the pre-formed wet blank needs to be dried inside the molding component 12. A reinforcing ring 222 is connected to one side of the inner wall of the molding component 12. To avoid interference from ultrasonic waves to the motor control, an acoustic shielding layer 17 is connected to one side of the reinforcing ring 222. The anti-interference motor 16 is located inside the acoustic shielding layer 17. The output end of the anti-interference motor 16 passes through the reinforcing ring 222 and is connected to a drying component 14. A sealing support frame 15 is connected between one end of the drying component 14 and the molding component 12 to ensure rotational stability.

[0025] Referring to Figures 1 and 2, in order to optimize the material flow path and extend the processing time, the dissociation chamber 2 is arranged in a vortex shape. To enhance wear resistance and electrical safety, the inner surface of the dissociation chamber 2 and the surface of the metal roller 3 are both provided with an insulating ceramic coating to prevent direct arcing between electrodes and ensure that only stable photoionization is generated.

[0026] Working principle: When the invention is in use, waste paper enters the vortex disintegration chamber 2 and is physically torn in the annular discharge gap formed between multiple sets of metal rollers 3 and the disintegration chamber 2. The tooth tips 301 on the surface of the metal rollers 3 generate a tip discharge between the metal rollers 3 and the chamber wall, forming a high-voltage electric field. This loosens the waste material on the one hand, and destroys the adhesives on the surface of the paper fibers, such as starch glue, ink and fiber bonding force, through corona discharge, causing some of them to fall off. The elastic component 4 keeps the metal rollers 3 floating and pressing the paper to ensure the tearing effect. At the same time, the squeezing roller 64 in the auxiliary component 6 is pressed tightly against the paper surface under the action of the spring 62, ensuring that the paper enters the processing stably and is effectively driven by the tooth tips 301. The initially disintegrated waste material enters the whistle shell 8. During the conveying process of the feeding auger 10, the spraying unit 11 sprays the composite biological enzyme preparation evenly on the surface of the paper through the atomizing nozzle 115. The enzyme preparation selectively degrades residual adhesive and gently cuts some of the excessively long fibers, achieving fiber modification and purification. Before entering the molding assembly 12, the variable frequency ultrasonic generator 131 on the reinforcing member 13 is activated. Its cavitation effect further promotes the dispersion of fibers in water and completely separates the loosened adhesive from the fiber surface. The slurry enters the molding assembly 12. The electromagnetic coil 124 on the insulating shell 121 interacts with the permanent magnet 123 on the molding hollow cylinder 122, driving the molding hollow cylinder 122 to rotate. At the same time, a vacuum pump connected to the quick-connect pipe creates a negative pressure inside the molding hollow cylinder 122. Moisture in the slurry is rapidly absorbed through the micropores inside the insulating shell 121, initially forming a wet paper blank on the surface of the forming hollow cylinder 122. The anti-interference motor 16 drives the drying assembly 14 to rotate inside the forming hollow cylinder 122. The microwave generating assembly 144 emits microwaves to uniformly heat and dry the wet paper blank from the inside out, which is highly efficient and energy-saving. The material gathering and stirring plate 145 pushes the material towards the outlet direction during rotation to prevent accumulation. The temperature and humidity sensor on the stationary cylinder 141 monitors and provides feedback to adjust the microwave power in real time to ensure drying quality. The acoustic shielding layer 17 protects the anti-interference motor 16 from ultrasonic waves.
