Description

Technical Field

[0001] This invention relates to the field of waste paperboard recycling, specifically to a device for manufacturing reinforced packaging paperboard from recycled waste paperboard and its usage method. Background Technology

[0002] With rapid economic growth and the development of logistics, the market demand for packaging cartons is increasing. Packaging cartons are a good packaging material due to their low cost and recyclability. Cartons are made from cardboard, which requires high strength. Currently, recycled waste cardboard is typically processed using recycling equipment. However, to increase the strength of recycled cardboard, reinforced packaging cardboard manufacturing equipment is needed.

[0003] A search revealed Chinese patent CN216330467U, which discloses a laminating device for packaging paperboard. The feeding assembly includes a conveyor roller for conveying the lower paperboard and an inclined conveyor belt for conveying the upper paperboard, located above the conveyor roller. The conveyor roller and conveyor belt respectively transport the upper and lower paperboards into the laminating assembly. An adhesive application assembly is located between the conveyor roller and the laminating assembly and applies adhesive to the lower paperboard. A pressing assembly is located on one side of the laminating assembly. An upper pressing cylinder and a lower pressing cylinder are located at the discharge ends of the conveyor belt and the conveyor roller, respectively. The upper and lower pressing cylinders drive an upper pressure plate and a lower pressure plate to move towards each other, aligning and pressing the ends of the upper and lower paperboards together. This invention prevents misalignment of the upper and lower paperboards during lamination, reducing paperboard waste and avoiding the tedious subsequent cutting process.

[0004] However, the aforementioned patents have the following problems: Although the upper and lower pressing cylinders drive the upper and lower pressing plates to move towards each other and align and press the ends of the upper and lower paperboards together, thus preventing misalignment during lamination, the purpose of laminating paperboard is to increase its strength. However, the increase in strength from laminating two rectangular paperboards together is relatively low, which may result in insufficient strength during use and affect the paperboard's usability.

The surface of each linkage gear is fixedly connected with a fixing rod rotatably connected to the inside of the base plate through a bearing seat.

[0015] This invention also discloses a method of using a reinforced packaging paperboard device manufactured from recycled waste paperboard. The method of using the aforementioned reinforced packaging paperboard device manufactured from recycled waste paperboard includes the following steps: S1. Apply glue to both sides of the cardboard, then place the cardboard on the opposite side of the upper and lower pressing plates. Through the cooperation of the drive motor and the drive rod, the cardboard enters the interior of the working box. Start the pressing motor, so that the two threaded rods drive the sliding block to slide downward, thereby making the upper pressing plate move synchronously. Through the cooperation of the upper and lower pressing plates, the cardboard is pressed, and the shape of the cardboard changes. S2. When the cardboard is pressed, the cardboard is limited by the setting of the limiting mechanism. After the cardboard is pressed, the upper pressing plate and the lower pressing plate are moved out of the working box shell by the drive motor, so that the connecting rod drives the drive tooth plate to move, so that the linkage gear rotates, so that the linkage component drives the drive gear to rotate, so that the four adjusting tooth plates move upward, which drives the lower bearing plate to move upward. S3. Start the electric push rod to make the lower pressure plate move downward synchronously, so that the cardboard on the lower support plate and the upper support plate come closer to each other and stick to the pressed cardboard, thereby connecting the three cardboards with glue; S4. When the moving plate moves to the outside of the working box housing, it makes the moving plate fit with the L-shaped plate, which causes the L-shaped plate to move synchronously with the pull rope, causing the two moving blocks to move, which causes the locking block to disengage from the locking rod. Then, through the elastic force of the return spring, the limiting plate and the adjusting block are reset, releasing the limiting mechanism from limiting the cardboard.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the setup of the base plate, working box assembly, pressing mechanism, bearing mechanism, and limiting mechanism, and through the cooperation of the drive motor and drive rod, the cardboard, upper pressing plate, and lower pressing plate enter the interior of the working box housing. The pressing motor is activated, causing the upper pressing plate to approach the lower pressing plate and squeeze the cardboard on opposite sides, thereby changing the shape of the cardboard and forming a wavy bend. Through the cooperation of the pressing mechanism and the bearing mechanism, the two square cardboards move closer to each other, so that the two cardboards and the two sides of the wavy cardboard are attached. At the same time, through the cooperation of the lower pressing plate and the lower bearing plate, the three cardboards are pressed together, and then glued together to complete the reinforcement of the packaging cardboard, making it stronger than two-layer composite cardboard. This avoids the packaging cardboard having low strength, which would result in insufficient strength during use and affect the use of the packaging cardboard. 2. Through the configuration of the working box assembly, pressing mechanism, bearing mechanism and limiting mechanism, when the moving plate moves the packaging paperboard, the packaging paperboard moves to the placement plate. At the same time, the pushing plate moves synchronously with the moving plate, thereby causing the pushing plate to push the locking rod to move, causing the adjusting block to move on the placement plate, thereby causing the rotating plate to rotate, so that one side of the rotating plate is in contact with the packaging paperboard, limiting and fixing the packaging paperboard to be pressed. Moreover, through the cooperation of the locking rod and the locking block, the limiting of the packaging paperboard is more stable, thereby making the packaging paperboard more stable during pressing and avoiding misalignment of the packaging paperboard due to displacement. 3. Through the design of the working box assembly, pressing mechanism, bearing mechanism, limiting mechanism, and release mechanism, when one of the packaging paperboards is pressed, the moving plate moves in the opposite direction. This, along with the limiting mechanism, prevents the pressed packaging paperboard from moving outside the working box housing along with the upper and lower pressing plates, thus facilitating further processing of the packaging paperboard. When the moving plate is attached to the L-shaped plate, it drives the L-shaped plate to move, causing the pull rope to move the moving block. This disengages the locking block and locking rod, resets the adjusting block, and resets the rotating plate. The rotating plate no longer limits the packaging paperboard, facilitating subsequent operations by the staff. 4. Through the structural design of the working box assembly, pressing mechanism, driving mechanism, bearing mechanism, limiting mechanism, and release mechanism, when the moving plate moves, it synchronously drives the connecting plate to move, causing the driving tooth plate to move synchronously. The movable groove makes the driving tooth plate more stable during movement. When the driving tooth plate moves, it synchronously drives the linkage gear to rotate, which in turn drives the drive gear to rotate, causing the adjusting tooth plate to move the lower bearing plate. At the same time, through the electric push rod and the lower pressure plate, the upper bearing plate moves downward, so that the three packaging cardboards are glued together, which facilitates the processing of packaging cardboard and improves the efficiency of packaging cardboard reinforcement.

[0021] Please see Figures 1-11In this embodiment of the invention, a device for manufacturing reinforced packaging paperboard from recycled waste paperboard includes a base plate 1 and a working box assembly 2. The working box assembly 2 includes a working box shell 201 fixedly connected to the upper surface of the base plate 1. Support plates 202 are fixedly connected to both sides of the inner bottom wall of the working box shell 201. Movable grooves 203 are formed on both sides of the inner bottom wall of the working box shell 201 near the support plates 202. Electric push rods 204 are fixedly connected in a rectangular array to the upper surface of the working box shell 201. The output ends of the four electric push rods 204 are fixedly connected to a lower pressure plate 205 slidably connected inside the working box shell 201. A pressing mechanism 3 is installed inside the working box assembly 2. The assembly mechanism 3 includes two drive motors 301 respectively installed at the two edges of one side of the working box assembly 2. A fixing plate corresponding to the two drive motors 301 is fixedly connected to one side of the working box housing 201. The two drive motors 301 are respectively fixedly connected to the two edges of one side of the working box housing 201. The output ends of the two drive motors 301 are fixedly connected to drive rods 302 that are rotatably connected to the working box assembly 2. The two drive rods 302 are rotatably connected to the working box housing 201. The surfaces of the two drive rods 302 are threadedly connected to movable plates 303. The two movable plates 303 are slidably connected to the corresponding support plates 202. The upper surfaces of the two movable plates 303 are fixedly connected to... A U-shaped plate is connected to each of the two drive motors 301. A pressing motor 304 is fixedly connected to the upper surface of each of the two moving plates 303. A threaded rod 305 is fixedly connected to the output end of each pressing motor 304. Sliding blocks 306 are threaded onto the surfaces of both threaded rods 305. An upper pressing plate 307 is fixedly connected to the opposite sides of the two sliding blocks 306. Sliding grooves 308, corresponding to the sliding blocks 306, are arranged in a path array on the opposite sides of the two moving plates 303. A lower pressing plate 309, opposite to the upper pressing plate 307, is fixedly connected to the inner bottom wall of several sliding grooves 308. One end of each threaded rod 305 is connected to the lower pressing plate 309 via a bearing seat. The assembly includes a 9-rotation connection, in which a stabilizing rod 310 is fixedly connected inside each of the four sliding grooves 308, and a stabilizing block fixedly connected to the upper pressing plate 307 is slidably connected to the surface of each stabilizing rod 310. A pushing plate 311 is fixedly connected to one side of each of the two moving plates 303. The assembly also includes a carrying mechanism 4, installed inside the work box assembly 2, for placing the corresponding cardboard; a limiting mechanism 5, installed on the inner wall of the work box assembly 2, for limiting the cardboard during pressing; a releasing mechanism 6, installed on the surface of the work box assembly 2, for releasing the limiting mechanism 5; and a driving mechanism 7, jointly installed on the surfaces of the two moving plates 303, for driving part of the carrying mechanism 4 to move.

[0022] In this embodiment: After applying glue to both sides of a cardboard, it is placed on the opposite sides of the upper pressing plate 307 and the lower pressing plate 309, so that the cardboard is in contact with the lower pressing plate 309. The drive motor 301 is started, and its output end drives the drive rod 302 to rotate, causing the two moving plates 303 to move into the working box housing 201. This causes the upper pressing plate 307 and the lower pressing plate 309 to move synchronously, thus moving the cardboard. When the cardboard moves into the working box housing 201, it is limited by the setting of the limiting mechanism 5. Then, the pressing motor 304 is started, and its output end drives the threaded rod 305 to rotate inside the sliding groove 308, thereby causing the upper pressing plate 307 to move downward and approach the lower pressing plate 309. The cooperation between plate 307 and lower pressing plate 309 changes the shape of the packaging paperboard, making it wavy, thus completing the pressing of one packaging paperboard. Then, the drive rod 302 rotates in the opposite direction, causing the moving plate 303 to move the upper pressing plate 307 and lower pressing plate 309 out of the working box housing 201. Through the setting of the limiting mechanism 5, the wavy packaging paperboard is clamped inside the working box housing 201. Then, through the cooperation between the carrying mechanism 4 and the pressing mechanism 3, the two paperboards placed on the carrying mechanism 4 are brought closer to each other, so that the two paperboards are close to the two sides of the wavy packaging paperboard. Through the setting of glue, the three paperboards are bonded together, thus processing the three paperboards into one packaging paperboard, improving the strength of the packaging paperboard. Please refer to this carefully. Figure 1 , Figure 2 , Figure 5 and Figure 7 The drive mechanism 7 includes four connecting rods 701 that are fixedly connected to the outside of the two movable plates 303 respectively. Each pair of corresponding connecting rods 701 are fixedly connected to one side of a drive gear plate 702 that is slidably connected inside the movable groove 203. Both sides of the surface of the drive gear plate 702 are meshed with linkage gears 703. The surface of each linkage gear 703 is fixedly connected with a fixed rod that is rotatably connected to the inside of the base plate 1 through a bearing seat. The surfaces of the two linkage gears 703 are meshed with linkage components 704. One end of each linkage component 704 is fixedly connected with a drive gear 705. The surfaces of the four drive gears 705 are meshed with an adjusting gear plate 706 that is slidably connected to the working box housing 201.

[0023] In this embodiment: after the upper pressing plate 307 and the lower pressing plate 309 are pressed together, the moving plate 303 moves in the opposite direction, thereby driving the connecting rod 701 to move synchronously, so that the two driving tooth plates 702 slide inside the corresponding movable groove 203. The movable groove 203 makes the two driving tooth plates 702 more stable when moving. When the driving tooth plates 702 move, the linkage gear 703 rotates, thereby causing the linkage component 704 to mesh and rotate synchronously, driving the driving gear 705 to rotate, thereby causing the four adjusting tooth plates 706 to move upward synchronously, driving part of the bearing mechanism 4 to move, thereby causing one of the packaging paperboards to move upward and fit with the pressed paperboard, completing the partial reinforcement of the packaging paperboard; Please refer to this carefully. Figures 1-7 The bearing mechanism 4 includes a lower bearing plate 401 slidably connected to the inside of the working box housing 201. One side of each of the four adjusting toothed plates 706 is fixedly connected to the two edges of the lower bearing plate 401.

Upper bearing plates 406 rotatably connected to the inside of the working box housing 201 are fixedly connected to the surfaces of each of the two rotating rods 404. The lower pressure plate 205 corresponds to the upper bearing plate 406.

[0024] In this embodiment: By setting up the upper support plate 406 and the lower support plate 401, two packaging paperboards are placed on their upper surfaces. When the adjusting tooth plate 706 moves the lower support plate 401, the electric push rod 204 is activated at the same time, causing its output end to move the lower pressure plate 205 downward synchronously. This causes the packaging paperboards on the surfaces of the two upper support plates 406 to move downward. By setting up the rotating rod 404, the two upper support plates 406 are bent, causing the packaging paperboards on the upper support plates 406 to move downward and adhere to the corrugated packaging paperboard. By setting up the glue, the packaging paperboards are adhered to the corrugated packaging paperboard, thereby completing the reinforcement of the packaging paperboards. By setting up the torsion spring 405, after the reinforcement of the packaging paperboards is completed, the electric push rod 204 is reset. By the elastic force of the torsion spring 405, the two upper support plates 406 are reset synchronously, thus facilitating the secondary bearing of the upper support plates 406. Please refer to this carefully. Figure 2 and Figures 8-10The limiting mechanism 5 includes through slots 501 on both sides of the inner wall of the working box housing 201. A rotating rod 502 is fixedly connected inside the through slots 501. A limiting plate 503 corresponding to the lower pressing plate 309 is slidably sleeved on the surface of the rotating rod 502. A return spring 504 fixedly connected to the through slots 501 is fixedly connected to both edges of one side of the limiting plate 503. A placement plate 505 corresponding to the limiting plate 503 is fixedly connected inside the two through slots 501. An adjustment mechanism 8 corresponding to the limiting plate 503 is slidably connected to the upper surface of the placement plate 505.

[0025] In this embodiment: the movement of the moving plate 303 causes the pushing plate 311 to move synchronously, thereby causing the adjusting mechanism 8 to move, and causing the limiting plate 503 to rotate inside the through groove 501 via the rotating rod 502, thereby causing one end of the limiting plate 503 to fit against the packaging paperboard, thereby limiting the packaging paperboard, making the packaging paperboard more stable when pressed by the upper pressing plate 307 and the lower pressing plate 309, and avoiding misalignment of the packaging paperboard; Please refer to this carefully. Figures 8-10 The adjustment mechanism 8 includes an adjustment block 801 slidably connected to the upper surface of the placement plate 505. Both sides of the lower surface of the adjustment block 801 are fixedly connected to the placement plate 505 with connecting springs 807. An elastic block 802 corresponding to the limiting plate 503 is slidably connected inside the adjustment block 801.

A moving block 805 slidably connected to the working box housing 201 is movably sleeved on the surface of the snap-fit ​​block 804. A spring assembly 806 fixedly connected to the working box housing 201 is fixedly connected to the two edges of one side of the moving block 805. Two snap-fit ​​springs 808 are fixedly connected symmetrically on one side of the snap-fit ​​block 804. The snap-fit ​​block 804 is slidably connected inside the moving block 805.

[0026] In this embodiment: when the moving plate 303 moves into the working box housing 201, the pushing plate 311 moves synchronously, thereby pushing the locking rod 803 to move, which in turn causes the adjusting block 801 to move on the upper surface of the placement plate 505, and thus causes the adjusting block 801 to move against the lower surface of the limiting plate 503. Through the setting of the elastic block 802, the limiting plate 503 rotates, thereby limiting the packaging cardboard. When the locking rod 803 moves to the locking block 804 and is in contact with it, the movement of the pushing plate 311 causes the locking block 804 to retract into the moving block 805, thereby compressing the locking spring 808, causing the locking rod 803 to move to one side of the locking block 804. Through the elastic force of the locking spring 808, the locking block 804 limits the locking rod 803, thereby keeping the position of the limiting plate 503 unchanged, and making the limiting plate 503 more stable in limiting the packaging cardboard. Please refer to this carefully. Figures 1-10 The release mechanism 6 includes two L-shaped plates 601 that are slidably connected inside the support plate 202 and correspond one-to-one with the two movable plates 303. A release spring 602 is fixedly connected to one side of each of the two L-shaped plates 601. Two corresponding pull ropes 603 are movably inserted into the interior of each of the two release springs 602. The two pull ropes 603 are slidably connected inside the support plate 202. One end of each pull rope 603 passes through the support plate 202 and is fixedly connected to one side of the movable block 805. The other end of each pull rope 603 is fixedly connected to the L-shaped plate 601.

[0027] In this embodiment: after the packaging cardboard is pressed into a wavy shape, the moving plate 303 moves to the outside of the working box housing 201, thereby causing the moving plate 303 to push the L-shaped plate 601 to move synchronously, causing the L-shaped plate 601 to pull the pull rope 603 to move inside the support plate 202, thereby causing the moving block 805 to move inside the working box housing 201, causing the locking block 804 to disengage from the locking rod 803, no longer limiting the locking rod 803, and thus the adjusting block 801 is reset by the elastic force of the connecting spring 807, thereby causing the limiting plate 503 to reset, no longer limiting the packaging cardboard, which facilitates further processing of the packaging cardboard, and through the cooperation of the spring assembly 806 and the locking spring 808, the L-shaped plate 601 and the moving block 805 can be reset with the moving plate 303, thereby facilitating the secondary use of the release mechanism 6 and the adjusting mechanism 8.

[0028] The following describes a method for using a device for manufacturing reinforced packaging paperboard from recycled waste paperboard, comprising the following steps: S1. Apply glue to both sides of the cardboard, then place the cardboard on the opposite side of the upper pressing plate 307 and the lower pressing plate 309. Through the cooperation of the drive motor 301 and the drive rod 302, the cardboard enters the interior of the working box housing 201. Start the pressing motor 304, so that the two threaded rods 305 drive the sliding block 306 to slide downward, thereby making the upper pressing plate 307 move synchronously. Through the cooperation of the upper pressing plate 307 and the lower pressing plate 309, the cardboard is pressed, so that the shape of the cardboard changes. S2. When the cardboard is pressed, the cardboard is limited by the setting of the limiting mechanism 5. After the cardboard is pressed, the upper pressing plate 307 and the lower pressing plate 309 are moved out of the working box housing 201 by the drive motor 301, thereby causing the connecting rod 701 to drive the drive tooth plate 702 to move, causing the linkage gear 703 to rotate, thereby causing the linkage component 704 to drive the drive gear 705 to rotate, thereby causing the four adjusting tooth plates 706 to move upward, which in turn causes the lower bearing plate 401 to move upward. S3. Start the electric push rod 204 to make the lower pressure plate 205 move downward synchronously, so that the cardboard on the lower support plate 401 and the upper support plate 406 approach each other and stick to the pressed cardboard, thereby connecting the three cardboards with glue. S4. When the moving plate 303 moves to the outside of the working box housing 201, the moving plate 303 comes into contact with the L-shaped plate 601, thereby causing the L-shaped plate 601 to drive the pull rope 603 to move synchronously, causing the two moving blocks 805 to move, thereby causing the locking block 804 to disengage from the locking rod 803, and thus the limit plate 503 and the adjusting block 801 are reset by the elastic force of the return spring 504, releasing the limit mechanism 5 from limiting the cardboard.
