Description

Technical Field

[0001] This invention relates to the field of biodegradable fiberboard production technology, specifically to an environmentally friendly production device and method for biodegradable fiberboard. Background Technology

[0002] Biodegradable fiberboard is an environmentally friendly board material made primarily from plant fibers (such as wood residues, crop straw, and bamboo fiber). It is produced through processes like pressing and molding, using biodegradable adhesives (rather than traditional, non-biodegradable chemical adhesives). In natural environments (such as soil and composting conditions), it is gradually decomposed into harmless substances by microorganisms, thus avoiding long-term environmental burden. It is widely used in various fields, serving as packaging materials such as cushioning linings for electronic products, food, and daily necessities, and as transport pallets, replacing traditional, non-biodegradable plastic packaging boards.

[0003] As an important category of environmentally friendly building materials, biodegradable fiberboard's production core lies in the precise mixing of various raw materials such as plant fibers, degrading agents, and adhesives into a uniform masterbatch. The mixing quality directly determines the board's degradation performance, mechanical strength, and service life.

[0004] However, traditional production equipment often uses a single-direction rotating impeller, resulting in a simple mixing trajectory. For raw materials with significant density differences (such as lightweight plant fibers and heavy biodegradable agents), centrifugal force easily leads to stratification, causing localized material enrichment. Furthermore, the impeller cannot move forward or backward or switch between forward and reverse rotation, making it difficult to adequately agitate the raw materials in different areas of the mixing chamber. In particular, unmixed materials tend to remain in the corners of the chamber walls, causing uneven composition of the masterbatch. This mixing defect directly leads to inconsistent degradation rates and insufficient localized strength in biodegradable fiberboard, reducing product yield. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an environmentally friendly production device and method for biodegradable fiberboard, solving the following problems: for raw materials with large density differences (such as lightweight plant fibers and heavy biodegrading agents), centrifugal force easily leads to "stratification," resulting in localized material enrichment; at the same time, the stirring paddle cannot achieve forward and backward movement and forward and reverse rotation, making it difficult to fully agitate the raw materials in different areas of the mixing chamber, especially since unmixed raw materials are easily left in the corners of the chamber walls, causing uneven composition of the masterbatch.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an environmentally friendly production device for biodegradable fiberboard, comprising a processing table, an electric slide rail provided on the inner side wall of the top of the processing table, a T-shaped moving plate slidably connected to the inner wall of the electric slide rail, a support plate fixedly connected to the surface of the rear end of the processing table, a storage bin being passed through and fixedly connected to the inner wall of the top of the support plate, a monitoring sensor provided on the outer side wall of the support plate, and a mixing and feeding mechanism provided on the right side wall of the T-shaped moving plate;

[0007] The mixing and feeding mechanism is used to fully crush and mix various raw materials for biodegradable fiberboard, so that they conform to the production masterbatch of biodegradable fiberboard.

[0010] Preferably, a side scraper is fixedly connected to the side of turntable b away from the center point of turntable a, and the side scraper is in contact with the inner arc surface of the mixing box.

[0011] Preferably, the rotating shaft is elastically connected to the inner wall of the rotating sleeve b by a reset spring, and a protrusion is fixedly connected to the outer arc surface of the rear end of the rotating shaft.

[0012] Preferably, the top of the outer wall of the T-shaped moving plate is in contact with the discharge port at the bottom of the storage tank, the bottom of the outer wall of the trapezoidal support block is in contact with the surface of the processing table, the left side of the top of the mixing box is hinged to the top of the right side wall of the T-shaped moving plate, and the bottom of the baffle is in contact with the surface of the processing table.

[0013] Preferably, a circular groove is provided on the right side wall of the mixing box, the turntable a is rotatably connected to the inner wall of the circular groove of the mixing box, the output shaft of the motor passes through and is rotatably connected to the center of the half gear, the three sets of gears mesh with the outer wall of the half gear, and the outer wall of the three sets of gears meshes with the inner side of the internal gear ring.

[0014] Preferably, the three sets of gears are fixedly connected to the rotation center shaft of the rotating sleeve b, the gears are rotatably connected to the inner side wall of the mixing box, the inner side of the rotating sleeve a is provided with an annular corrugated groove, and the protrusion is slidably connected to the inner wall of the annular corrugated groove of the rotating sleeve a.

[0015] Preferably, one end of the return spring is fixedly connected to the outer sidewall of the rotating shaft, and the other end of the return spring is fixedly connected to the inner sidewall of the rotating sleeve b.

[0016] Preferably, an environmentally friendly production method for biodegradable fiberboard includes the following steps:

[0017] S1. Device initialization check: Check the connection status of the electric slide rail, support plate, top storage bin, T-shaped moving plate and mixing feeding mechanism on the inner side of the top of the processing table. Ensure that the left side of the top of the mixing box is firmly hinged to the top of the right side wall of the T-shaped moving plate, and that the bottom of the baffle and trapezoidal support block are in close contact with the surface of the processing table. At the same time, activate the monitoring sensor on the outside of the support plate to put it into working state for subsequent monitoring of raw material feeding residue.

[0018] S2. Raw material loading: Load the various raw materials required for the production of biodegradable fiberboard into the storage tank according to the ratio. At this time, the T-shaped moving plate is in the initial position. Its left side structure of the T-shape blocks the bottom of the storage tank to prevent the raw materials from falling in advance and ensure that the raw materials are temporarily stored in the storage tank.

[0019] S3. Raw material quantitative feeding control: Start the electric slide rail and drive the T-shaped moving plate to move laterally to the left along the inner wall of the electric slide rail until the notch on the right side of the top of the T-shaped moving plate is completely aligned with the bottom feeding port of the storage bucket. The biodegradable fiberboard raw material in the storage bucket falls into the mixing box along the notch. When the raw material feeding amount reaches the preset value, control the electric slide rail to drive the T-shaped moving plate to move back to the right, so that the left side of the T-shaped moving plate covers the feeding port of the storage bucket again, and the feeding stops.

[0020] S4. Raw Material Mixing and Dispersing Operation: Start the motor in the mixing and feeding mechanism. The motor output shaft drives the triangular plate and turntable a to rotate synchronously. The three sets of gears rotatably connected to the surface of the triangular plate move circumferentially with the triangular plate. At the same time, the gears mesh with the outer wall of the half gear and the inner side of the inner gear ring, respectively. Under the meshing action, the gears themselves rotate. When meshing with the half gear, they rotate clockwise, and when meshing with the inner gear ring, they rotate counterclockwise. The gears drive the rotating sleeve b, whose rotation center axis is fixed, to rotate synchronously. The rotating sleeve b drives the rotating shaft to rotate through the inner guide groove. The multiple sets of stirring rods on the surface of the rotating shaft rotate with it. The rotating shaft performs alternating forward and reverse circumferential motion; simultaneously, the protrusion at the rear end of the rotating shaft slides in the annular corrugated groove inside the rotating sleeve a, driving the rotating shaft to move back and forth on the inner walls of rotating sleeve a and rotating sleeve b, and the stirring rod moves back and forth synchronously; in addition, the side scrapers fixed on the side of rotating disk a and rotating disk b away from the center point rotate synchronously with the rotating disks, scraping off the raw materials adsorbed on the inner side wall of the mixing box. Through the forward and reverse rotation, back and forth movement and circumferential revolution of the stirring rod, as well as the scraping action of the side scrapers, the raw materials are fully mixed and dispersed to form biodegradable fiberboard production masterbatch that meets the requirements.

[0021] S5. Post-mixing raw material monitoring: After the mixing and dispersing operation is completed, the monitoring sensor detects whether there is any raw material residue in the mixing box. If residue is detected, the motor is restarted to drive the stirring rod and side scraper to run for a preset time until the residual raw material is cleaned up. If no residue is detected, proceed to the next step.

[0022] S6. Discharge of masterbatch: Start the electric slide rail and drive the T-shaped moving plate to continue moving to the right along the inner wall of the electric slide rail, which in turn drives the mixing box to move to the right. As it moves, the bottom of the trapezoidal support block gradually detaches from the surface of the processing table. The mixing box, having lost its support, tilts downward around the hinge point between itself and the T-shaped moving plate. At the same time, the baffle at the bottom right side of the mixing box detaches from the surface of the processing table as the mixing box tilts. Under the action of gravity, it rotates around the hinge point to open the discharge port of the mixing box. The mixed biodegradable fiberboard masterbatch is discharged from the discharge port along the inclined inner wall of the mixing box, completing the discharge.

[0023] S7. Device Reset and Preparation for Next Production: After material discharge is completed, control the electric slide rail to drive the T-shaped moving plate to move back to the left, and the mixing box moves to the left synchronously. When the trapezoidal inclined surface of the trapezoidal support block contacts the surface of the processing table, under the guidance of the inclined surface, the mixing box rotates upward around the hinge point to return to the center. At the same time, the baffle rotates around the hinge point to close the discharge port of the mixing box under the support of the surface of the processing table. Continue to drive the T-shaped moving plate back to the initial position, and its left side covers the discharge port of the storage bucket again. The device returns to the initial state and waits for the next batch of raw materials to be filled and processed.

[0024] This invention provides an environmentally friendly production apparatus and method for biodegradable fiberboard. It has the following beneficial effects:

[0025] 1. This invention achieves efficient and uniform mixing of raw materials through a multi-dimensional stirring structure of "forward and reverse rotation + forward and backward movement + circumferential revolution": The motor-driven triangular plate drives three sets of gears to revolve around the center, with the gears alternately meshing with the half gear (clockwise rotation) and the internal gear ring (counterclockwise rotation), so that the stirring rod synchronously achieves forward and reverse rotation; at the same time, the protrusion at the rear end of the rotating shaft slides along the annular corrugated groove of the rotating sleeve a, driving the stirring rod to move back and forth, which, together with the side scrapers driven by turntables a and b, scrapes away residues on the box wall, forming a multi-dimensional mixing trajectory of "revolution + forward and reverse rotation + forward and backward disturbance + wall cleaning". This design completely solves the problem of "layering and dead corners" in traditional stirring, ensuring uniform dispersion of components such as plant fibers, degradation agents, and adhesives.

[0026] 2. This invention relies on the synergistic design of "inclined discharge + side scraper cleaning" to achieve residue-free and environmentally friendly production: During discharge, the electric slide rail drives the T-shaped moving plate to move the mixing box to the right. After the trapezoidal support block is disengaged, the mixing box tilts around the hinge point, the baffle opens automatically, and the masterbatch is quickly discharged along the inclined box wall. At the same time, the side scraper rotates synchronously with the turntable to continuously scrape off the raw materials (especially viscous fiber materials) adsorbed on the box wall. No manual cleaning is required, saving more than 80% of cleaning time.

[0027] 3. This invention achieves automated continuous production through the linkage control of a T-shaped moving plate and each process: When the T-shaped moving plate moves to the left, its notch aligns with the material discharge port of the storage bin, precisely controlling the falling of raw materials. Simultaneously, the trapezoidal support block pushes the mixing box back to its original position and closes the baffle, completing quantitative feeding. After mixing is completed, the T-shaped moving plate moves to the right to trigger discharge, and during the movement, the left side of the T-shaped plate always blocks the material discharge port of the storage bin to prevent accidental feeding. The entire process requires no manual switching of equipment status, realizing feeding-mixing-cleaning-discharging-resetting. Attached Figure Description

[0036] The technical solutions in 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.

[0037] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides an embodiment of an environmentally friendly production device and method for biodegradable fiberboard, comprising a processing table 1, an electric slide rail 2 mounted on the inner wall of the top of the processing table 1, and a T-shaped moving plate 5 slidably connected to the inner wall of the electric slide rail 2. The top of the outer wall of the T-shaped moving plate 5 contacts the discharge port at the bottom of the storage bin 4. The T-shaped moving plate 5 is T-shaped, and can be driven to move laterally on its surface by the electric slide rail 2, thereby driving the mixing and feeding mechanism 6 to move. A notch is provided on the right side of the T-shaped top of the T-shaped moving plate 5. Through the movement of the T-shaped moving plate 5, the notch aligns with the discharge port at the bottom of the storage bin 4, allowing the biodegradable fiberboard raw material placed inside to fall into the mixing bin through the notch of the T-shaped moving plate 5. The material is thoroughly mixed and dispersed inside the feeding mechanism 6. The left side of the T-shaped moving plate 5 blocks the feeding port of the storage bin 4, effectively preventing the material inside the storage bin 4 from falling. A support plate 3 is fixedly connected to the surface of the rear end of the processing table 1. The storage bin 4 is fixedly connected through the inner wall of the top of the support plate 3. A monitoring sensor 7 is set on the outer side wall of the support plate 3. By setting the monitoring sensor 7, it can be determined whether the biodegradable fiberboard raw material after mixing and dispersing in the mixing box 601 has been fully fed, avoiding the residue of the previously processed material. A mixing and feeding mechanism 6 is set on the right side wall of the T-shaped moving plate 5. The mixing and feeding mechanism 6 is used to fully crush and mix the various raw materials of biodegradable fiberboard, so that they meet the production masterbatch of biodegradable fiberboard.

[0038] The mixing and feeding mechanism 6 includes a mixing box 601. The bottom end of the outer wall of the trapezoidal support block 603 contacts the surface of the processing table 1. The top left side of the mixing box 601 is hinged to the top of the right side wall of the T-shaped moving plate 5. The bottom end of the baffle 602 contacts the surface of the processing table 1. The T-shaped moving plate 5 drives the mixing box 601 to move as a whole. When the baffle 602, which is hinged at the bottom right end of the mixing box 601, is no longer in contact with the processing table 1, it will tilt and open due to its own hinge, thereby discharging the material inside the mixing box 601 outward. At the same time, as the mixing box 601 moves until the trapezoidal support block 603 is no longer in contact with the surface of the processing table 1, the mixing box 601, lacking the support of the trapezoidal support block 603, will rotate around the hinge point at its upper left corner on the side wall of the T-shaped moving plate 5, thereby tilting the mixing box 601. This allows for better discharge of the mixed and dispersed biodegradable fiberboard masterbatch. The bottom end of the trapezoidal support block 603 forms a trapezoidal shape. The inclined surface faces left, and the hinge point of the baffle 602 is also on the left. This allows the T-shaped moving plate 5 to move the mixing box 601 to the left to replenish new biodegradable fiberboard raw materials for mixing and dispersing. Simultaneously, the inclined surface of the trapezoidal support block 603 contacts the side wall of the processing table 1, thus straightening the mixing box 601 around the hinge point. At the same time, the contact between the baffle 602 and the inclined surface blocks the discharge port at the bottom of the mixing box 601. As the T-shaped moving plate 5 moves... The notch will be aligned with the discharge port of the storage hopper 4, allowing the raw material to enter the mixing box 601 through the notch. When the mixing box 601 is tilted to discharge material, the discharge port at the bottom of the storage hopper 4 will be blocked by the T-shaped deformation on the left side of the T-shaped moving plate 5 to prevent the material from falling. The bottom right side of the mixing box 601 has a discharge port, and the inner side wall of the discharge port of the mixing box 601 is hinged with a baffle 602. The bottom right side of the outer wall of the mixing box 601 is fixedly connected with a trapezoidal support block 603.

[0039] An internal gear ring 604 is fixedly connected to the right side wall of the mixing box 601. A connecting plate 605 is fixedly connected to the surface of the internal gear ring 604. A motor 607 is fixedly connected to the end of the connecting plate 605 away from the internal gear ring 604. A half gear 606 is fixedly connected to the rear end surface of the connecting plate 605 and the motor 607. The internal gear ring 604 is fixed to the side wall of the mixing box 601. It supports and fixes the motor 607 and the half gear 606 through the connecting plate 605. A triangular plate 608 is fixedly connected to the output shaft of the motor 607. Three sets of gears 610 are rotatably connected to the surface of the triangular plate 608. A turntable a609 is fixedly connected to the rotation center of the triangular plate 608. When the output shaft of the motor 607 drives the triangular plate 608 to rotate, it also drives the turntable a609 to rotate synchronously. A circular groove is opened on the right side wall of the mixing box 601. The turntable a609 is rotatably connected to the inner wall of the circular groove of the mixing box 601.

[0040] The output shaft of motor 607 passes through and is rotatably connected to the center of half gear 606. Three sets of gears 610 mesh with the outer wall of half gear 606, and the outer walls of the three sets of gears 610 mesh with the inner side of internal gear ring 604. When triangular plate 608 is driven to rotate by motor 607, it drives the three sets of gears 610 to rotate synchronously. Simultaneously, because the rotating sleeve b612 connected to the center of gear 610 passes through the interior of turntable a609, when triangular plate 608 drives the three sets of gears 610 to rotate, the three sets of gears 610 drive the rotating sleeve b612 to rotate, and simultaneously drive turntable a609 to rotate synchronously. This allows the three sets of gears 610 to rotate circumferentially following triangular plate 608. The gear 610 meshes with the internal gear ring 604 and the half gear 606, causing the three sets of rotating sleeves b612 to drive the rotating shaft 613 and the stirring rod 614 on its surface. When the gear 610 meshes with the half gear 606, the gear 610 rotates clockwise. When it meshes with the internal gear ring 604, it rotates in the opposite direction. This causes the three sets of rotating shafts 613 to drive the stirring rod 614. While the gear 610 follows the turntable a609 around the center, it also switches between forward and reverse rotation. This allows the biodegradable fiberboard material inside the mixing box 601 to be fully mixed and dispersed, making it conform to the biodegradable fiberboard production masterbatch.

[0041] Three sets of rotating sleeves b612 are rotatably connected through the inner wall of the turntable a609. Three sets of gears 610 are fixedly connected to the rotation center shaft of the rotating sleeve b612. A rotating shaft 613 is slidably connected to the inner side wall of the rotating sleeve b612. A guide groove that fits the rotating shaft 613 is opened inside the rotating sleeve b612, so that the rotating shaft 613 can only move back and forth on the inner wall of the rotating sleeve b612. At the same time, when the rotating sleeve b612 rotates, it will drive the rotating shaft 613 to move synchronously. Multiple sets of stirring rods 614 are fixedly connected to the surface of the rotating shaft 613. The outer wall of the end of the rotating shaft 613 away from the rotating sleeve b612 contacts the rotating sleeve a611. The rear end of the rotating sleeve a611 is fixedly connected to the turntable b616. When the rotating shaft 613 rotates with the rotating sleeve b612, it will drive the rotating sleeve a611 to rotate synchronously, and at the same time, it will drive the turntable b616 to rotate synchronously. The turntable b616 can support the three sets of rotating sleeves a611.

[0042] A side scraper 615 is fixedly connected to the side of turntable b616 and turntable a609 away from the center point. The side scraper 615 contacts the inner arc surface of the mixing box 601. When turntable a609 and turntable b616 rotate circumferentially inside turntable b616, they will drive the side scraper 615 to reciprocate around the center inside the mixing box 601. This can scrape off the raw materials adsorbed inside the mixing box 601, so that the raw materials will be adsorbed inside the mixing box 601 during discharge. At the same time, it can also increase the mixing effect of the raw materials and avoid the raw materials adsorbed inside the mixing box 601, which would lead to insufficient dispersion and mixing.

[0043] The rotating shaft 613 is elastically connected to the inner wall of the rotating sleeve b612 via a return spring 617. One end of the return spring 617 is fixedly connected to the outer wall of the rotating shaft 613, and the other end is fixedly connected to the inner wall of the rotating sleeve b612. The function of the return spring 617 is to automatically reset the position of the rotating shaft 613 after it has moved the stirring rod 614. A protrusion 618 is fixedly connected to the outer arc surface of the rear end of the rotating shaft 613. The gear 610 is rotatably connected to the inner wall of the mixing box 601. The inner side of the rotating sleeve a611 is provided with... The annular corrugated groove and the protrusion 618 are slidably connected to the inner wall of the annular corrugated groove of the rotating sleeve a611. The movement of the protrusion 618 on the inner wall of the annular corrugated groove of the rotating sleeve a611 causes the rotating shaft 613 to drive the stirring rod 614 to move on the inner wall of the rotating sleeve a611 and the rotating sleeve b612. This causes the stirring rod 614 to move back and forth on the inner wall of the mixing box 601 to break up the biodegradable fiberboard raw material inside the mixing box 601. The reset spring 617 ensures that the rotating shaft 613 is always elastically supported.

[0044] An environmentally friendly production method for biodegradable fiberboard includes the following steps:

[0045] S1. Device initialization check: Check the connection status of the electric slide rail 2, support plate 3, top storage tank 4, T-shaped moving plate 5 and mixing and feeding mechanism 6 on the inner side of the top of the processing table 1. Ensure that the top left side of the mixing box 601 is firmly hinged to the top right side wall of the T-shaped moving plate 5, and that the bottom of the baffle 602 and trapezoidal support block 603 are in close contact with the surface of the processing table 1. At the same time, activate the monitoring sensor 7 on the outside of the support plate 3 to put it into working state for subsequent monitoring of raw material feeding residue.

[0046] S2. Raw material loading: The various raw materials required for the production of biodegradable fiberboard are loaded into the storage tank 4 according to the ratio. At this time, the T-shaped moving plate 5 is in the initial position. Its T-shaped left side structure blocks the bottom discharge port of the storage tank 4 to prevent the raw materials from falling in advance and to ensure that the raw materials are temporarily stored in the storage tank 4.

[0047] S3. Raw material quantitative feeding control: Start the electric slide rail 2 and drive the T-shaped moving plate 5 to move laterally to the left along the inner wall of the electric slide rail 2 until the notch on the right side of the top of the T-shaped moving plate 5 is completely aligned with the bottom feeding port of the storage bucket 4. The biodegradable fiberboard raw material in the storage bucket 4 falls into the mixing box 601 along the notch. When the raw material feeding amount reaches the preset value, control the electric slide rail 2 to drive the T-shaped moving plate 5 to move back to the right, so that the left side of the T-shaped moving plate 5 covers the feeding port of the storage bucket 4 again, and the feeding stops.

[0048] S4. Raw material mixing and dispersing operation: Start the motor 607 in the mixing and feeding mechanism 6. The output shaft of the motor 607 drives the triangular plate 608 and the turntable a609 to rotate synchronously. The three sets of gears 610 rotatably connected to the surface of the triangular plate 608 move circumferentially with the triangular plate 608. At the same time, the gears 610 mesh with the outer wall of the half gear 606 and the inner side of the inner gear ring 604 respectively. Under the meshing action, the gears 610 themselves rotate. When meshing with the half gear 606, they rotate clockwise, and when meshing with the inner gear ring 604, they rotate counterclockwise. The gears 610 drive the rotating sleeve b612, which is fixed to its rotation center axis, to rotate synchronously. The rotating sleeve b612 drives the rotating shaft 613 to rotate through the inner guide groove. The multiple sets of gears on the surface of the rotating shaft 613... The stirring rod 614 moves in a circumferential motion, alternating between forward and reverse rotation, along with the rotating shaft 613. Simultaneously, the protrusion 618 at the rear end of the rotating shaft 613 slides within the annular corrugated groove on the inner side of the rotating sleeve a611, causing the rotating shaft 613 to reciprocate back and forth along the inner walls of the rotating sleeves a611 and b612. The stirring rod 614 moves back and forth synchronously. Furthermore, the side scraper 615, fixed on the side of the turntables a609 and b616 away from the center point, rotates synchronously with the turntables, scraping off the raw materials adsorbed on the inner wall of the mixing box 601. Through the forward and reverse rotation, back and forth movement, and circumferential revolution of the stirring rod 614, as well as the scraping action of the side scraper 615, the raw materials are fully mixed and dispersed to form a biodegradable fiberboard production masterbatch that meets the requirements.

[0049] S5. Monitoring of raw materials after mixing: After the mixing and dispersing operation is completed, the monitoring sensor 7 detects whether there is any raw material residue in the mixing box 601. If residue is detected, the control motor 607 is restarted to drive the stirring rod 614 and the side scraper 615 to run for a preset time until the residual raw material is cleaned up.
