[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The apparatus for preparing honeycomb paper cores from waste paper scraps according to an embodiment of the present invention includes: The pretreatment box 1 and the feeding assembly are provided. The pretreatment box 1 has a processing chamber 101. The feeding assembly is set in the processing chamber 101. The feeding assembly includes a feeding shell 21 and a partition plate 22. The feeding shell 21 has a material distribution channel 2. Multiple partition plates 22 are installed in the material distribution channel 2. A guide channel is formed between adjacent partition plates 22. The fiber protection unit 100 includes a fiber protection mechanism comprising a rotating shaft 3, paddles 4, a drive motor 23, a buffer plate 6, and a guide plate 7. The rotating shaft 3 is rotatably mounted inside the feed housing 21. Multiple paddles 4 are evenly distributed on the rotating shaft 3. One end of the rotating shaft 3 is connected to the output shaft of the drive motor 23. The drive motor 23 is fixedly mounted on the outer wall of the pretreatment box 1. A buffer plate 6 is provided at the bottom of the distribution channel 2. The buffer plate 6 is connected to the inner wall of the distribution channel 2 by a spring. A guide plate 7 is provided below the buffer plate 6. The separation unit 200 includes a separation shell, a screen frame 11, and an exhaust assembly. The separation shell has a separation chamber 8. A guide plate 7 is inclined and communicates with the inlet of the separation chamber 8. The screen frame 11 is fixedly installed at the bottom of the separation chamber 8, and a filter screen is embedded in the screen frame 11. The exhaust assembly includes an exhaust pipe and a dust collector. An exhaust pipe is provided on one side of the separation chamber 8, and the other end of the exhaust pipe is connected to the dust collector. A discharge port is provided at the bottom of the separation chamber 8. The conveying unit 300 and the forming unit 400 are configured such that the input end of the conveying unit is connected to the separating unit to receive the material output from the separating unit, and the output end of the conveying unit is connected to the forming unit. The molding unit 400 includes a molding die 16, a pressing mechanism, a heating component 18, and a cooling component. The pressing mechanism is provided on the top of the molding die 16. The pressing mechanism includes a drive rod and a pressure plate. The drive rod and the pressure plate are connected by threads. The bottom of the pressure plate has evenly distributed protrusions. The heating component 18 is provided on one side of the molding die 16. A heat-conducting plate is fixedly installed on the bottom of the heating component 18. The heat-conducting plate is in contact with the outer wall of the molding die 16. The cooling component is provided on the other side of the molding die 16. Multiple sets of cooling pipes 19 are embedded in the cooling component. The two ends of the cooling pipes 19 are connected to an inlet pipe and an outlet pipe, respectively.

[0028] Specifically, such as Figures 1 to 8 As shown, multiple sets of partition plates are installed in the material distribution channel 2, forming evenly distributed guide channels to guide waste paper into the separation chamber 8. A removable filter screen is embedded in the screen frame 11 to separate waste paper fibers from impurities. A dust collector is used to collect dust and light impurities generated during the separation process.

[0029] The cooling pipe 19 is connected to an inlet pipe and an outlet pipe at both ends to quickly reduce the temperature of the honeycomb paper core after molding. The bottom of the pressure plate has evenly distributed raised structures to compact waste paper fibers to form the product. These evenly distributed raised structures on the bottom of the pressure plate can simultaneously compact and form a regular honeycomb hexagonal structure during hot pressing, improving specific strength and compressive strength. The heating component 18 directly contacts the mold with the heat-conducting plate, and in conjunction with the rapid water cooling of the cooling pipe 19, achieves a temperature-controlled cycle of "heating-molding-cooling," significantly shortening the production cycle and preventing product cracking and deformation.

[0030] The separation chamber 8, combined with the physical filtration of the screen frame 11 and the airflow separation of the exhaust component, forms a dual separation of "gravity + wind," which can efficiently remove non-fibrous impurities such as tape, plastic film, and staples from waste paper. The screen frame 11 adopts a detachable filter design, which makes it easy to replace the filter with different mesh sizes according to the type of waste paper, and it is easy to clean blockages, ensuring the stability of continuous production. The apparatus for preparing honeycomb paper cores using waste paper scraps in this invention solves the problems of significant fiber damage and difficult impurity removal in traditional waste paper pulping by pre-treating fibers for fiber protection and separating impurities to facilitate subsequent molding. A pressure plate with uniformly distributed raised structures on its bottom is used to compact the waste paper fibers to form the product. These uniformly distributed raised structures on the bottom of the pressure plate can simultaneously compact and form a regular hexagonal honeycomb structure during hot pressing, improving specific strength and compressive strength. The heating component 18 directly contacts the mold with the heat-conducting plate, and with rapid water cooling via the cooling pipe 19, the prepared honeycomb paper core has advantages such as regular structure, high strength, and low cost. It achieves a temperature-controlled cycle of "heating-molding-cooling," significantly shortening the production cycle, preventing product cracking and deformation, and improving production efficiency and product quality. By optimizing the fiber protection mechanism and molding process, the apparatus solves the problems of easily damaged waste paper fibers, low molding efficiency, and insufficient resource utilization in existing technologies. This technical solution further integrates multi-stage pretreatment modules and dynamic forming mechanisms to realize the conversion of scrap paper, while improving the strength performance and production efficiency of honeycomb paper cores.

[0031] Furthermore, the pretreatment box 1 also has a discharge port, and the output end of the molding die 16 is connected to the discharge port for outputting the molded material. The molding unit can be an existing molding device or molding equipment.

[0032] In some embodiments, the conveying unit 300 includes a conveyor belt assembly 13 and baffles 20. The inlet of the conveyor belt assembly 13 is connected to the discharge port, and the outlet of the conveyor belt assembly 13 is connected to the forming mold 16. Baffles 20 are fixedly installed on both sides of the conveyor belt assembly, and air vents are evenly distributed on the baffles 20. The air vents evenly distributed on the baffles can promote the humidity regulation of waste paper during the conveying process.

[0033] In some embodiments, the apparatus for preparing honeycomb paper cores from waste paper scraps further includes an airflow regulating mechanism. An airflow regulating mechanism is provided in the separation chamber 8. The airflow regulating mechanism includes an airflow distributor 9, an air supply pipe, and a fan. The airflow distributor 9 is fixedly installed on the top of the separation chamber 8. Multiple sets of air jet holes 10 are evenly opened at the bottom of the airflow distributor 9. The outlet direction of the air jet holes 10 is towards the screen frame 11. One side of the airflow distributor 9 is connected to the air supply pipe, and the other end of the air supply pipe is connected to the fan.

[0034] Specifically, such as Figures 1 to 8As shown, one side of the airflow distributor 9 is connected to an air supply pipe, and the other end of the air supply pipe is connected to a fan to deliver a stable airflow into the separation chamber 8. A discharge port is located at the bottom of the separation chamber 8, and the discharge port is connected to the inlet of the conveyor belt 13 via a flexible hose. During actual operation, the airflow distributor 9 delivers a uniform airflow above the screen frame 11 through the jet nozzle 10. The airflow disperses the waste paper fibers and distributes them evenly on the screen frame 11, while simultaneously discharging light impurities through the suction pipe. The elastic scraper 12 moves back and forth at the bottom of the screen frame 11 to promptly clean residues and prevent clogging, thereby improving separation efficiency.

[0035] In some embodiments, the conveying unit 300 further includes a humidity regulating mechanism and a temperature regulating component. The humidity regulating mechanism is provided on the conveyor belt assembly 13. The humidity regulating mechanism includes a spray head 14, a water supply pipe and a water storage tank. The spray head 14 is fixedly installed on the top of the baffle 20. The spray head 14 is connected to the water storage tank through the water supply pipe. The water storage tank is fixedly installed on the outer wall of the pretreatment chamber 1. A humidity sensor is provided below the spray head 14. The humidity sensor is fixedly installed on the inner side of the baffle 20. The temperature regulating component includes a heating plate and a temperature controller. A heating plate is provided at the bottom of the conveyor belt. The heating plate is connected to the temperature controller through a wire. The temperature controller is fixedly installed on the outer wall of the pretreatment chamber 1.

[0036] Specifically, such as Figures 1 to 8 As shown, a humidity sensor is installed below the spray head 14, fixedly mounted inside the baffle, for real-time monitoring of the waste paper's humidity. A heating plate is installed at the bottom of the conveyor belt 13, connected to a temperature controller via wires. The temperature controller is fixedly mounted on the outer wall of the pretreatment chamber 1 to regulate the heating plate's temperature. During actual operation, when the humidity sensor detects that the waste paper's humidity is below a set value, the spray head 14 sprays an appropriate amount of water onto the waste paper based on the feedback signal, ensuring the waste paper fibers are within a suitable humidity range. The heating plate's temperature is regulated by the temperature controller, further optimizing the waste paper's physical state and providing pre-set raw material conditions for subsequent forming processes.

[0037] Furthermore, the water storage tank includes a tank body and a water pump. The tank body stores water, one end of the water pump is connected to the tank body, and the other end of the water pump is connected to the spray head 14.

[0038] In some embodiments, the dynamic molding mechanism includes a vibrator 17, which is fixedly installed at the bottom of the molding mold 16. The top of the vibrator 17 is fixedly connected to the bottom plate of the molding mold 16 via a connector. A displacement sensor is provided on one side of the vibrator 17 and is fixedly installed on the outer peripheral surface of the molding mold. Multiple sets of grooves are evenly distributed on the inner wall of the molding mold 16, and vent holes are provided at the bottom of the grooves. A temperature sensor is fixedly installed on the outer wall of the molding mold 16 and is connected to the heating component 18 via a wire.

[0039] Specifically, such as Figures 1 to 8 As shown, the inner wall of the forming mold 16 has multiple sets of grooves evenly distributed, and the bottom of the grooves is provided with vent holes to promote the uniform distribution of waste paper fibers. A temperature sensor is fixedly installed on the outer wall of the forming mold 16, and the temperature sensor is connected to the heating component 18 through wires to monitor the temperature of the forming mold 16. In actual operation, after the waste paper fibers enter the forming mold 16, the vibrator 17 drives the forming mold 16 to generate high-frequency vibration, so that the waste paper fibers are evenly distributed and tightly compacted in the mold. The displacement sensor monitors the vibration amplitude in real time to ensure the stability of the forming process. The heating component 18 provides heat to the forming mold 16 through a heat conduction plate, so that the waste paper fibers can be quickly shaped. The cooling pipe 19 in the cooling component uses circulating water to quickly reduce the temperature of the honeycomb paper core after forming, thereby improving production efficiency and ensuring product quality.

[0040] In some embodiments, the number of spray heads 14 is multiple, and the multiple spray heads 14 are evenly distributed along the length direction of the conveyor belt.

[0041] In some embodiments, the apparatus for preparing honeycomb paper cores from scrap waste paper further includes a flexible pad 5, which is fixedly connected to the outer side of the lever 4. The flexible pad 5 on the lever 4 performs preliminary dispersion treatment on the waste paper while preventing damage to the waste paper fibers due to mechanical action. After passing through the buffer plate 6 and the guide plate 7, the waste paper enters the separation chamber 8, a process that effectively reduces the breakage of waste paper fibers.

[0042] In some embodiments, the outer periphery of the buffer plate 6 is coated with an anti-slip layer, the anti-slip layer being made of polyurethane. A buffer plate 6 is provided at the bottom of the feeding channel 2, the buffer plate 6 being connected to the inner wall of the feeding channel 2 by a spring, and the surface of the buffer plate 6 being covered with an anti-slip layer to reduce the impact force when waste paper falls.

[0043] Furthermore, the guide channels within the material distribution channel 2 are uniformly distributed rectangular channels with a fixed width.

[0044] In some embodiments, the apparatus for preparing honeycomb paper cores from scrap waste paper further includes a scraping assembly, which includes a telescopic member and an elastic scraper 12. The telescopic member is disposed in the processing chamber 101, extends into the separation chamber 8 and is connected to the elastic scraper 12, and the elastic scraper 12 contacts the bottom of the screen frame 11.

[0045] The elastic scraper 12 contacts the screen frame 11 to clean the residue on the screen frame 11.

[0046] The rotating shaft 3 and the paddle 4 in the material distribution channel 2 perform preliminary dispersion of waste paper. The flexible pad 5 reduces mechanical damage to the waste paper fibers. The design of the buffer plate 6 and the guide plate 7 further prevents fiber breakage caused by excessive impact during the fall of waste paper. The airflow regulation mechanism in the separation chamber 8 forms a stable airflow environment through the airflow distributor 9 and the jet hole 10, which helps to evenly distribute waste paper fibers and separate impurities. The design of the elastic scraper 12 can clean the residue at the bottom of the screen frame 11 in time, avoiding blockage. The humidity regulation mechanism on the conveyor belt 13 ensures that the waste paper fibers are within a suitable humidity range through the spray head 14 and the humidity sensor. The heating plate regulates the temperature through the temperature controller to optimize the physical state of the waste paper. The dynamic forming mechanism ensures that the waste paper fibers are evenly distributed and tightly compacted in the mold through the vibrator 17 and the displacement sensor. The heating component 18 and the cooling component work together to achieve rapid shaping and cooling of the honeycomb paper core. By organically combining the above-mentioned mechanisms, this invention achieves efficient conversion of waste paper scraps, significantly improves the strength performance and production efficiency of honeycomb paper cores, and reduces resource waste, thus meeting the dual requirements of environmental protection and economic benefits.

[0047] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principles of this invention are further supplemented below with a specific application scenario.

[0048] First, the operator feeds scrap paper into the pretreatment chamber 1 through the feed hopper. Under gravity, the waste paper enters the sorting channel 2. At this time, the rotating shaft 3 begins to rotate under the drive of an external motor, and the paddle 4 rotates synchronously to initially disperse the waste paper. The flexible pad 5 on the outside of the paddle 4 provides cushioning when it comes into contact with the waste paper, reducing mechanical damage to the waste paper fibers. Next, the waste paper falls onto the buffer plate 6, which is connected to the inner wall of the sorting channel 2 by a spring. The anti-slip layer covering its surface effectively absorbs the impact force of the falling waste paper, preventing fiber breakage due to excessive impact. Then, the waste paper slides along the inclined guide plate 7 into the separation chamber 8, ensuring a smooth transition to the next processing stage.

[0049] After entering the separation chamber 8, the airflow distributor 9 delivers a uniform airflow above the screen frame 11 through the jet nozzle 10. The airflow disperses the waste paper fibers and distributes them evenly on the screen frame 11, while light impurities are blown up and discharged into the dust collector through the suction pipe. The elastic scraper 12 moves back and forth close to the bottom of the screen frame 11 to clean up residues in time and prevent the screen frame 11 from clogging, thereby improving the separation efficiency of waste paper fibers and impurities. After separation, the waste paper fibers fall onto the conveyor belt 13 through the discharge port and move forward with the conveyor belt 13.

[0050] During the operation of conveyor belt 13, a humidity sensor monitors the humidity of the waste paper in real time. When the humidity of the waste paper is detected to be too low, the humidity sensor sends a signal to spray head 14, which sprays an appropriate amount of water onto the waste paper according to set parameters to maintain the waste paper fibers within a suitable humidity range. At the same time, the heating plate at the bottom of conveyor belt 13 regulates the temperature through a temperature controller to optimize the physical state of the waste paper and prepare it for subsequent forming processes. The ventilation holes on the baffles promote uniform humidity distribution of the waste paper during conveying.

[0051] When the waste paper fibers reach the end of the conveyor belt 13, the vibrator 17 starts and drives the forming mold 16 to generate high-frequency vibration, so that the waste paper fibers are evenly distributed and tightly compacted in the mold. The displacement sensor monitors the vibration amplitude in real time to ensure that the vibration process is stable and meets the process requirements. The groove and vent design on the inner wall of the forming mold 16 helps to further evenly distribute the waste paper fibers and vent air, avoiding voids or uneven density during the forming process. Subsequently, the heating component 18 provides heat to the forming mold 16 through the heat conduction plate, so that the waste paper fibers can be quickly shaped. The cooling pipe 19 in the cooling component quickly reduces the temperature of the formed honeycomb paper core through circulating water, thereby completing the final forming of the honeycomb paper core. The pretreatment box 1 may also be provided with a discharge port connected to the output end of the forming mold 16 to discharge the product of the forming mold 16. In the above steps, the design features and operating principles of each mechanism work together to achieve efficient conversion of waste paper scraps. For example, the rotating shaft 3 and the paddle 4 in the material distribution channel 2 reduce the possibility of fiber shortening by dispersing the waste paper; the coordinated design of the buffer plate 6 and the guide plate 7 further reduces mechanical damage to the waste paper during transportation. The airflow regulation mechanism in the separation chamber 8 significantly improves the separation efficiency of waste paper fibers and impurities through a stable airflow environment and the cleaning function of the elastic scraper 12. The humidity regulation mechanism on the conveyor belt 13 ensures that the waste paper fibers are always within the optimal humidity range through the cooperation of the spray head 14 and the humidity sensor, while the heating plate regulates the temperature through the temperature controller to further optimize the plasticity of the waste paper. The dynamic forming mechanism, through the coordinated operation of the vibrator 17, displacement sensor, heating component 18 and cooling component, not only achieves uniform distribution and compaction of waste paper fibers, but also significantly improves the strength performance and production efficiency of the honeycomb paper core.
