Description

Technical Field

[0001] This invention relates to the field of cardboard waste recycling and packaging technology, specifically to an integrated device for recycling and packaging waste from packaging cardboard boxes. Background Technology

[0002] Packaging cartons are packaging containers made primarily of corrugated cardboard. They are lightweight, sturdy, inexpensive, and easy to process. They not only effectively protect the contents from physical damage such as impact and vibration, but also have excellent printability. They play an important role in brand display and information transmission. After use, they need to be recycled to provide high-quality raw materials for new paper products, which helps improve the efficiency of reuse in practice.

[0003] In existing technologies, the typical workflow for recycling and packaging waste cardboard boxes usually begins with a conveyor belt feeding waste cardboard boxes into a shredder for shredding. The shredded, fluffy paper scraps are then conveyed into a compression chamber via a conveyor. A high-power hydraulic cylinder drives a pressure head to compress the material in the chamber at high intensity to reduce its volume. Finally, after compression, an automatic bundling mechanism bundles the dense paper blocks to form neat recycling bales for subsequent transportation and recycling.

[0004] When shredding packaging cardboard waste, the loose waste can bridge or arch at the exit, causing inconsistent material flow into the compression chamber, or even interruptions. This not only directly disrupts the continuity of the compression process and reduces the efficiency of the entire production line, but also results in inconsistent material levels within the compression chamber. Consequently, the compressed bales are uneven in density, loose in shape, and prone to springing back, severely impacting the quality of the recycled bales and their storage and transportation value. Furthermore, frequent shutdowns for unblocking increase equipment maintenance costs and the intensity of manual intervention.

[0005] While this method can solve the problem of loose waste bridging or arching at the outlet and ensure smooth feeding, the compressed blocks exhibit springback due to their inherent characteristics. If springback cannot be effectively suppressed, the compressed blocks will expand rapidly after being pushed out, necessitating pressure holding operations. Although pressure holding can be achieved through hydraulic cylinders, prolonged use of hydraulic cylinders without mechanical pressure holding forces the motor and oil pump in the hydraulic system to operate continuously to maintain pressure. This leads to a significant increase in energy consumption and a sharp rise in hydraulic oil temperature. High temperatures accelerate oil oxidation and deterioration, as well as the aging of sealing elements. This not only exacerbates the wear rate of key hydraulic components such as oil pumps and valves, shortening their service life, but also causes a gradual decrease in pressure holding due to increased leakage within the system. Ultimately, the compressed blocks will still spring back even under insufficient pressure holding conditions, severely affecting the stability of the finished product quality. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an integrated waste recycling and packaging device for cardboard boxes. This device not only solves the problem of material bridging but also addresses how to mechanically maintain pressure on the compressed blocks, thus resolving the issues raised in the background art.

[0007] The present invention provides the following technical solution: an integrated device for recycling and packaging waste from packaging cartons, including a base, a compression pushing bin fixedly installed on the upper surface of the base, a support frame fixedly installed on the upper surface of the base, and an arch-breaking and pressure-holding mechanism provided on the left side of the upper surface of the compression pushing bin. The arch-breaking and pressure-holding mechanism has a push-limiting mechanism at one power output end that converts the waste material compression force into a limiting force, and a locking constant pressure mechanism at the other power output end that converts the waste material compression force into a locking force; the locking constant pressure mechanism has an arch-breaking mechanism at its power output end that converts the downward pressure into a rotational force. The arch-breaking and pressure-holding mechanism is composed of a pushing limit mechanism, a locking constant pressure mechanism, and an arch-breaking mechanism.

[0008] Preferably, the pushing and limiting mechanism includes a mold box, a connecting frame, a top plate, a main compression cylinder, a connecting block, a rounded corner block one, a compression block, a connecting spring, a telescopic rod, and a rounded corner block two.

Locking grooves are formed on both sides of the mold box.

[0009] Preferably, the locking constant pressure mechanism includes a receiving frame, a rack, an L-shaped plate, a rotating shaft, a gear, a gear, a locking block, and a rack.

[0010] Preferably, the arch-breaking mechanism includes a fixed frame, a temporary storage hopper, a baffle plate, a rack, a gear, a rotating rod, and transverse blades. The front of the fixed frame is fixedly installed on the back of the upper side of the support frame. The front of the temporary storage hopper is fixedly installed on the back of the fixed frame.

One end of the transverse blade is fixedly installed on the outer surface of the rotating rod, and multiple sets of transverse blades are provided. The front of the rack meshes with the outer surface of the gear, and the left side of the rack is fixedly installed on one side of the receiving frame.

[0011] Preferably, the first rounded corner block is driven by the power of the main compression cylinder to push the second rounded corner block, causing the compression block to slide down the inner wall of the mold box. After being pressed down, the compression block maintains pressure on the waste block. When the compression block moves upward, the power of the main compression cylinder drives the first rounded corner block to enter the lower surface of the second rounded corner block, thus moving the compression block upward. A stop block is fixedly installed on the back of the connecting frame, and when the receiving frame installed on the upper surface of the compression block passes through the stop block, the first rounded corner block moves to the upper surface of the second rounded corner block, thus solving the limitation on the compression block and allowing the compression block to fall.

[0016] Preferably, a fixing plate is fixedly installed on the right side of the upper surface of the base, and an ejection cylinder is installed on the right side of the fixing plate. A push block is fixedly installed at one end of the output shaft of the ejection cylinder, and the outer surface of the push block is slidably installed with the outer surface of the compression push chamber.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This integrated waste recycling and packaging device for cardboard boxes utilizes a locking constant pressure mechanism, including rack one, gear one, gear two, rack two, and locking blocks. After locking, the main compression cylinder can immediately unload and retract, causing the motor and oil pump in the hydraulic system to stop working. This eliminates the huge energy waste and system overheating caused by prolonged hydraulic pressure holding, reduces operating costs, and effectively avoids problems such as high-temperature deterioration of hydraulic oil, aging of seals, and accelerated wear of components. It comprehensively improves the reliability and service life of the hydraulic system, extends the equipment maintenance cycle, and reduces overall operation and maintenance costs.

[0018] 2. This integrated waste recycling and baling device for packaging cartons converts the downward power of the main compression cylinder into the arch-breaking action of the transverse blades and the mechanical pressure-holding action of the locking block. This achieves efficient coordination between the feeding and compression processes, eliminates the bridging problem of loose waste at the outlet of the temporary storage hopper, ensures that the material entering the mold box is continuous and uniform, achieves continuous pressure holding without energy consumption, suppresses the rebound of paper fibers, and produces high-quality recycled bales with uniform density, regular shape, and resistance to loosening, thereby improving the storage and transportation value of the product.

[0019] 3. This integrated waste recycling and packaging device for packaging cartons, through the use of a push-limiting mechanism, rounded corner block one and rounded corner block two, etc., works in conjunction with the stop block to reliably realize the pressing, limiting and lifting reset of the compression block. It combines the power source of the arch-breaking mechanism with the main compression system, simplifies the structure and control, avoids product quality fluctuations caused by the decrease in holding pressure, ensures the stability and safety of packaging operations, and is suitable for high-intensity industrial continuous production environments.

[0022] 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.

[0023] Please see Figure 1 , Figure 5 and Figure 6An integrated device for recycling and packaging waste from cardboard boxes includes a base 1, a compression pushing bin 10 fixedly installed on the upper surface of the base 1, a support frame 2 fixedly installed on the upper surface of the base 1, and an arch-breaking and pressure-holding mechanism provided on the left side of the upper surface of the compression pushing bin 10. The power output end of the arch breaking and pressure holding mechanism is equipped with a push limiting mechanism that converts the waste material compression force into a limiting force, and the other power output end of the arch breaking and pressure holding mechanism is equipped with a locking constant pressure mechanism that converts the waste material compression force into a locking force; the power output end of the locking constant pressure mechanism is equipped with an arch breaking mechanism that converts the downward pressure into a rotational force. The arch-breaking and pressure-holding mechanism is composed of a pushing limit mechanism, a locking constant pressure mechanism, and an arch-breaking mechanism. The pushing limit mechanism includes a mold box 15, a connecting frame 17, a top plate 18, a main compression cylinder 19, a connecting block 20, a rounded corner block 1 21, a compression block 22, a connecting spring 23, a telescopic rod 24, and a rounded corner block 25. The bottom of the mold box 15 is fixedly installed on the left side of the upper surface of the compression push chamber 10. The bottom of the connecting frame 17 is fixedly installed on the upper surface of the mold box 15. The lower surface of the top plate 18 is fixedly installed on the upper surface of the connecting frame 17. The bottom end of the main compression cylinder 19 is installed on the top end of the top plate 18. The upper surface of the connecting block 20 is fixedly installed on one end of the output shaft of the main compression cylinder 19. The upper surface of the rounded corner block 1 21 is fixedly installed on the lower surface of the connecting block 20. The outer surface of the compression block 22 is slidably connected to the inside of the mold box 15. A rectangular groove 26 is opened inside the compression block 22. One end of the connecting spring 23 is fixedly installed on the left side inside the rectangular groove 26. One end of rod 24 is fixedly installed inside the rectangular groove 26 on the left side. The left side of rounded corner block 25 is fixedly installed to the other end of connecting spring 23 and telescopic rod 24. One side of the lower surface of rounded corner block 21 is fitted to the right side of the upper surface of rounded corner block 25. Locking grooves 16 are provided on both sides of mold box 15. Rounded corner block 21 is driven by the power of main compression cylinder 19 to push rounded corner block 25, so that compression block 22 slides down the inner wall of mold box 15. After being pressed down, the compression block 22 maintains pressure on the waste block. When the compression block 22 moves upward, the power of the main compression cylinder 19 drives the rounded corner block 21 to enter the lower surface of the rounded corner block 25, which in turn drives the compression block 22 to move upward. The back of the connecting frame 17 is fixedly installed with a stop block 27, and when the receiving frame 28 installed on the upper surface of the compression block 22 passes through the stop block 27, the rounded corner block 21 moves to the upper surface of the rounded corner block 25, which solves the limitation on the compression block 22 and allows the compression block 22 to fall.

[0024] Specifically, by driving the limiting mechanism and locking constant pressure mechanism, the compression force of the waste material is rationally converted, providing stable pressure during compression to ensure that the waste material is fully compressed and shaped, thus improving the packaging quality. On the other hand, a pressure-holding operation can be performed after compression to prevent the waste material from rebounding, ensuring a sustained and stable compression effect. The anti-arching mechanism set at the power output end of the locking constant pressure mechanism can convert the downward pressure into rotational force, effectively solving the arching problem that may occur during the compression process, ensuring the smooth progress of the compression process, and enabling the waste material to be compressed evenly and tightly, further improving the packaging effect. The main compression cylinder 19 provides powerful and stable power, which is transmitted to the rounded corner block 21 via the connecting block 20. The fitting design of the rounded corner block 21 and the rounded corner block 25 ensures precise power transmission, enabling the compression block 22 to slide stably down the inner wall of the mold box 15, achieving precise compression of the waste material and avoiding deviation or instability during compression, thus improving the compression quality. During the upward movement of the compression block 22, the main compression cylinder 19 drives the rounded corner block 21 into the lower surface of the rounded corner block 25, which in turn drives the compression block 22 to move upward smoothly. The operation is simple and the control is precise. When the receiving frame 28 mounted on the upper surface of the compression block 22 passes the stop block 27 on the back of the connecting frame 17, the rounded corner block 1 21 can move to the upper surface of the rounded corner block 25, releasing the restriction on the compression block 22 and allowing it to fall. This flexible up-and-down movement control mechanism allows the device to quickly and accurately adjust the position of the compression block 22 according to different work requirements, improving the applicability and work efficiency of the device. Moreover, after the compression block 22 is pressed down, it performs a pressure-holding operation on the waste block, which can effectively maintain the compressed state of the waste, prevent the waste from rebounding, and ensure a long-lasting and stable compression effect. At the same time, a rectangular groove 26 is opened inside the compression block 22, and a connecting spring 23 and a telescopic rod 24 are set in it. The connecting spring 23 and the telescopic rod 24 are connected to the rounded corner block 25, which can play a certain buffering role during the compression process, reducing the damage to the device caused by excessive instantaneous pressure and extending the service life of the device.

[0025] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8The constant pressure locking mechanism includes a receiving frame 28, a rack 29, an L-shaped plate 30, a rotating shaft 31, a gear 32, a gear 33, a locking block 34, and a rack 41. The front of the L-shaped plate 30 is fixedly installed with the back of the compression pusher hopper 10. The outer surface of the rotating shaft 31 is rotatably installed with the inner wall of the L-shaped plate 30. The inside of the gear 32 is fixedly installed with the outer surface of the rack 29. The inside of the gear 33 is fixedly installed with the outer surface of the rack 29. The upper surface of the rack 41 meshes with the outer surface of the gear 33. The back of the locking block 34 is fixedly installed with the front of the rack 41. The right side of the rack 29 meshes with the outer surface of the gear 32. The top of the rack 29 is fixedly installed with one side of the receiving frame 28. The bottom of the receiving frame 28 is fixedly installed with the upper surface of the compression block 22. When the locking block 34 moves through the rack 41, it can enter the locking groove 16 to limit and lock the compression block 22.

[0026] Specifically, the constant pressure locking mechanism is connected to the compression block 22 via the receiving frame 28. When the compression block 22 completes the compression action and reaches a specific position, the receiving frame 28 drives the rack 29 to move. Since the rack 29 meshes with gear 32 and gear 33 respectively, its movement drives gear 33 to rotate, which in turn drives the meshing rack 41 to move, ultimately causing the locking block 34 to enter the locking groove 16, thereby achieving the limiting and locking of the compression block 22. This effectively prevents the compression block 22 from moving unexpectedly during pressure holding or other operations, ensuring the quality and stability of waste material compression and packaging. During the compression and pressure maintenance process of the compression block 22, the constant pressure locking mechanism fixes the compression block 22 in a specific position through the cooperation of the locking block 34 and the locking groove 16, so that it can continuously apply stable pressure to the waste. Stable pressure can ensure that the waste is fully compacted, reduce the voids inside the waste, improve the density and strength after baling, and avoid the waste rebound or loose baling caused by unstable pressure, thereby ensuring the effect of waste recycling and baling.

[0027] Please see Figure 1 , Figure 9 and Figure 10The arch-breaking mechanism includes a fixed frame 6, a temporary storage hopper 7, a baffle plate 36, a rack 37, a gear 38, a rotating rod 39, and a transverse blade 40. The front of the fixed frame 6 is fixedly installed on the back of the upper side of the support frame 2. The front of the temporary storage hopper 7 is fixedly installed on the back of the fixed frame 6. The lower surface of the baffle plate 36 is fixedly installed on the left side of the upper surface of the temporary storage hopper 7. The outer surface of the rotating rod 39 is rotatably installed on the inner wall of the baffle plate 36. The inside of the gear 38 is fixedly installed on one end of the rotating rod 39. One end of the transverse blade 40 is fixedly installed on the outer surface of the rotating rod 39, and multiple sets of transverse blades 40 are provided. The front of the rack 37 meshes with the outer surface of the gear 38. The left side of the rack 37 is fixedly installed on one side of the receiving frame 28. A valve 8 is installed at the outlet of the temporary storage hopper 7. A discharge pipe 9 is installed at the outlet of the valve 8. The outer surface of the bottom end of the discharge pipe 9 is installed inside the compression pushing bin 10.

[0028] Specifically, during the waste processing, waste may form an arched structure in the temporary storage hopper 7 due to accumulation or moisture, leading to poor discharge or even blockage. The arch-breaking mechanism, through the movement of the receiving frame 28, drives the rack 37 to move. The rack 37 meshes with the gear 38, which in turn drives the rotating rod 39 to rotate. The multiple sets of transverse blades 40 on the rotating rod 39 rotate accordingly, which can powerfully stir and agitate the waste in the temporary storage hopper 7, effectively breaking the arched structure formed by the waste and allowing it to fall smoothly. This avoids blockages that could affect the normal operation of the entire waste processing process, improving the equipment's efficiency and stability. The arch-breaking mechanism is connected to the receiving frame 28, realizing linkage with other actions in the compression and packaging process. When the receiving frame 28 moves under the drive of the relevant actions of the compression pushing bin 10, it will drive the arch-breaking mechanism to work in sync, which simplifies the structure of the equipment, reduces energy consumption and cost, and at the same time ensures the coordination between the arch-breaking operation and the waste compression and packaging process, making the entire equipment run more smoothly.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The top of the support frame 2 is fixedly installed with the crusher shell 3. Both sides of the crusher shell 3 are equipped with drive motors 4. One end of the output shaft of the drive motor 4 is equipped with a shearing blade 5. The bottom of the crusher shell 3 is equipped with a discharge plate 35, and one side of the discharge plate 35 is in contact with one side of the baffle plate 36. The back of the lower side of the support frame 2 is fixedly installed with a fixing frame 2 11. The back of the fixing frame 2 11 is fixedly installed with the front of the compression pusher bin 10. The right side of the upper surface of the base 1 is fixedly installed with a fixing plate 12. The right side of the fixing plate 12 is equipped with a pusher cylinder 13. One end of the output shaft of the pusher cylinder 13 is fixedly installed with a pusher block 14. The outer surface of the pusher block 14 is slidably installed with the outer surface of the compression pusher bin 10.

[0030] Specifically, drive motors 4 are installed on both sides of the crusher housing 3, which is fixedly mounted at the top of the support frame 2. The output shaft of the drive motor 4 drives the shearing blades 5 to rotate at high speed. When waste enters the crusher housing 3, the shearing blades 5 can powerfully cut and crush the waste, breaking large, irregular pieces of waste into smaller and relatively uniform particles or blocks, facilitating subsequent compression and baling, improving the efficiency and quality of waste processing, making the waste easier to compress and shape, and reducing resistance during the compression process. The bottom of the crusher housing 3 has a discharge plate 35 that fits against one side of the baffle plate 36. This design ensures that the crushed waste can fall smoothly and accurately from the crusher housing 3 into the temporary storage hopper 7. The discharge plate 35 plays a guiding and buffering role, preventing waste from splashing or clogging during the discharge process, ensuring a smooth connection between the crushing and discharge stages, and enabling the entire waste processing process to proceed continuously and stably. An ejector cylinder 13 is installed on the fixing plate 12 fixedly mounted on the right side of the upper surface of the base 1. The output shaft of the ejector cylinder 13 drives the push block 14 to slide on the outer surface of the compression push chamber 10. After the waste material is compressed and packaged in the compression push chamber 10, the ejector cylinder 13 provides a strong thrust, and pushes the compressed waste material package out of the compression push chamber 10 through the push block 14, realizing the rapid and efficient output of the waste material package, which facilitates subsequent transportation and storage, and improves the automation level and work efficiency of the entire waste material processing process.

[0031] Working principle: During use, the drive motor 4 starts, driving the shearing blade 5 to rotate and shred the waste cardboard boxes fed into the crusher casing 3. The shredded material slides into the temporary storage hopper 7 through the discharge plate 35. At this time, the valve 8 is in the closed state. When the material in the temporary storage hopper 7 reaches a certain amount, the valve 8 opens, and the material enters the mold box 15 in the compression push chamber 10 through the discharge pipe 9. Subsequently, the main compression cylinder 19 starts, and its output shaft extends downward, pushing the connecting block 20 and the rounded corner block 21 downward together. In the initial stage of the downward movement of the main compression cylinder 19, the receiving frame 28, which is rigidly connected to the compression block 22, moves downward accordingly. The receiving frame 28 drives the rack 37 on its side to move downward synchronously. The rack 37 drives the meshing... Gear 38 rotates, which in turn drives the rotating rod 39 and the multiple sets of transverse blades 40 fixed thereon to rotate above the discharge port of the temporary storage hopper 7, stirring the material and breaking the formed arch, ensuring a continuous and uniform supply of material to the compression chamber. At the same time as the arch-breaking action occurs, the main compression cylinder 19 continues to move downward, overcoming the elastic force of the connecting spring 23 through the inclined surface contact of rounded corner block 1 21 and rounded corner block 25, pushing the entire compression block 22 to slide downward in the mold box 15, performing a powerful compression operation on the waste material. At the same time, the receiving frame 28 also drives the rack 29 on it to move downward, and the rack 29 drives the gear 32 meshing with it to rotate. The gear 32 drives the gear at the other end through the rotating shaft 31. The gear 23 rotates synchronously, and the gear 23 drives the meshing rack 241 to move horizontally to the right, thereby pushing the locking block 34 to move towards the locking groove 16 on the side of the mold box 15. When the compression block 22 descends to the compression end point, that is, when the waste block reaches the predetermined density, the locking block 34 is just fully inserted into the locking groove 16. Using the wedge principle or the over-center locking principle, the compression block 22 is mechanically locked in the current position. At this time, although the main compression cylinder 19 can immediately unload and lift its output shaft, driving the rounded corner block 21 to move upward, the compression block 22 itself is firmly fixed by the locking block 34, continuing to apply constant pressure to the waste block in the cavity to achieve mechanical pressure holding. During the mechanical pressure holding period, the external automatic strapping equipment can be activated to pressurize the block. The compressed waste blocks are bundled together. After bundling, the output shaft of the main compression cylinder 19 is fully retracted, causing the locking block 34 to exit from the locking groove 16 and releasing the lock on the compressed block 22. Subsequently, the ejection cylinder 13 is activated, pushing the push block 14 to push the bundled finished product block out of the compression push chamber 10. After the ejection action is completed, the ejection cylinder 13 retracts, all structures are reset, and it is ready to enter the next working cycle. The upward reset of the compressed block 22 is achieved by the main compression cylinder 19 lifting it to below the rounded corner block 25 through the rounded corner block 1 21. When passing the stop block 27, the mechanism causes the rounded corner block 1 21 to return to above the rounded corner block 25, releasing the lifting of the compressed block 22 and allowing it to fall freely to the initial position.

[0032] In this device, the drive motor 4 can be a Y-series three-phase asynchronous motor, model Y160M-4, to provide stable power for shredding. The main compression cylinder 19 and the ejection cylinder 13 must be engineering hydraulic cylinders with a rated pressure of not less than 21MPa, such as the HSG series. The model is selected according to the specific stroke and thrust. The valve 8 can be configured as a normally closed two-position two-way solenoid directional valve, such as model 2V025-08. The linkage operation between them is centrally controlled by a programmable logic controller (PLC): its workflow begins with the drive motor 4 starting to drive the shearing blade 5 to complete the shredding. After the material falls into the temporary storage hopper 7, the PLC sends a signal to energize the electromagnet of the valve 8 to open for quantitative feeding. Then the valve 8 closes and the main compression cylinder 19 extends to perform compression and triggers the locking constant pressure mechanism at the end of the stroke to achieve mechanical pressure holding. During the pressure holding period, the PLC immediately controls the hydraulic system of the main compression cylinder 19 to unload its rod and retract it. After the binding signal is completed, the PLC commands the ejection cylinder 13 to extend and eject the finished bale, thus forming an energy-saving, efficient and continuous automated cycle.
