Description

Technical Field

[0001] This invention relates to the field of automated equipment for the production and manufacturing of insulation boards, specifically an automatic stacking device for the production and manufacturing of insulation boards. Background Technology

[0002] In the current rapid development of the building materials industry, insulation boards, as a core material for energy-saving buildings, are experiencing continuous expansion in production scale and output. In the insulation board production process, the stacking stage is a crucial node connecting production, warehousing, and transportation, directly impacting production efficiency and the smoothness of subsequent logistics. With the popularization of automated production concepts, traditional manual stacking methods are no longer sufficient to meet the demands of large-scale, high-paced production. The industry's need for efficient and stable automated stacking devices is increasingly urgent. Especially since insulation boards are mostly lightweight and fragile board structures, the stacking process must balance efficiency and safety to avoid boards falling off or being damaged due to improper operation. This places higher demands on the adsorption and fixing capabilities, dimensional adaptability, and stacking accuracy of automated stacking devices.

[0003] While some automated insulation board stacking equipment exists on the market, most devices have significant defects in the adsorption and fixing process. Traditional devices often employ a single pneumatic suction cup or mechanical clamping structure. The former is prone to adsorption and sealing failure due to dust and debris residue on the insulation board surface, leading to board detachment during transfer; the latter may damage the insulation board surface due to improper clamping force control, affecting product quality. Furthermore, existing devices typically have a fixed gripping range. When dealing with insulation boards of different lengths and widths, frequent machine stops are required to change clamps or manually adjust equipment parameters, extending production cycles and increasing labor costs, making it difficult to meet the flexible production needs of diverse varieties and small batches.

[0004] Furthermore, existing automated stacking devices still have shortcomings in stacking stability and precision control. Some devices lack an effective centering adjustment mechanism, and after the insulation boards are placed in the stacking area, the boards are prone to shifting, causing the stack to tilt. This requires manual re-adjustment and reduces stacking efficiency. Even if some devices are equipped with a closing structure, they cannot adaptively adjust the closing range according to the length-to-width ratio of the insulation boards. When the length and width of the boards differ significantly, incomplete closing or excessive compression can easily occur, affecting stack neatness and potentially causing hidden damage to the boards. These problems not only restrict the improvement of automation levels in insulation board production but also increase production costs and quality control difficulties for enterprises. There is an urgent need for a new type of automated stacking device that can solve the problems of adsorption reliability, size adaptability, and stacking precision. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic stacking device for the production of insulation boards, which solves the problems of easy adsorption and detachment of insulation boards during stacking, difficulty in adapting to different sizes, easy stacking deviation, and the need for manual cleaning and adjustment, thereby improving stacking efficiency and stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic stacking device for insulation board manufacturing, comprising a material gripping robot, a control chamber fixedly installed at the drive end of the material gripping robot, the bottom end of the control chamber fixedly installed at the top center of a square channel steel support, adjusting rods movably installed at the four edges of the bottom end of the square channel steel support via limiting bushings, pneumatic suction cups fixedly installed at the ends of the adjusting rods, a rotating column movably installed inside the control chamber, a driving bevel gear fixedly installed at the top of the rotating column, threaded rods movably installed around the inner sidewalls of the control chamber, short shafts fixedly installed at the inner ends of the threaded rods, driven bevel gears provided on the outer diameter of the middle part of the short shafts, and the bottom ends of the driven bevel gears meshing with the top of the driving bevel gears, movable blocks threadedly connected to the outer diameter of the threaded rods, L-shaped extension rods fixedly installed at both ends of the movable blocks, and retracting plates fixedly installed at the ends of the extension rods extending to the outside of the control chamber.

[0007] Preferably, a rotating disk is movably mounted on the bottom center of the square channel steel bracket via a movable shaft. Four extension frames are evenly fixedly mounted on the outer wall of the rotating disk. Each extension frame has a straight groove. A positioning pin is fixedly mounted on the inner side of the bottom of the adjusting rod, and the end of the positioning pin extends into the inside of the straight groove on the corresponding side. An electric cylinder is movably mounted on one side of the bottom of the square channel steel bracket, and the end of the electric cylinder is movably mounted on one side of the top of the rotating disk.

[0008] Preferably, the square channel steel support has weight-reducing through holes at all four corners, an adsorption chamber is fixedly installed inside each weight-reducing through hole, a negative pressure chamber is opened at the bottom of each adsorption chamber, and a negative pressure fan is fixedly installed in the middle of each adsorption chamber.

[0009] Preferably, an air jet pipe is fixedly installed at the top center of each adsorption chamber, and the end of each air jet pipe extends to one side of the corresponding pneumatic suction cup and is fixedly installed with a nozzle. A density rubber ring is fixedly installed on the outer side of the bottom of each adsorption chamber.

[0010] Preferably, a compression spring is fixedly installed on the outer diameter of the short shaft near the threaded rod, and the end of the compression spring abuts against the outer end of the driven bevel gear on the corresponding side.

[0011] Preferably, a chuck is fixedly installed on the outer diameter of the short shaft away from the threaded rod, and a number of round hole slots are opened on the inner side of the driven bevel gear. A number of round head pins are fixedly installed on the end of the chuck near the driven bevel gear, and the ends of the round head pins extend into the interior of the corresponding round hole slot.

[0012] Preferably, limit guide rods are fixedly installed on both sides of the inner wall of the control room near each threaded rod, and the outer diameter of the limit guide rods is movably installed on the inner sides of the corresponding movable block.

[0013] Preferably, a worm gear is fixedly installed on the outer diameter of the middle part of the rotating column, and a geared motor is fixedly installed on one side of the control room. The drive end of the geared motor extends into the interior of the control room and a worm is fixedly installed thereon. The worm is meshed with the inner end of the worm gear.

[0014] This invention provides an automatic stacking device for the production of insulation boards. It has the following advantages:

[0015] 1. This invention innovatively employs a dual adsorption structure of "pneumatic suction cup + negative pressure chamber." A negative pressure fan draws air from the negative pressure chamber to create a strong negative pressure, which, combined with the adsorption effect of the pneumatic suction cup, achieves dual fixation of the insulation board. This design effectively avoids the problem of insulation boards falling off during transfer due to insufficient adsorption force. Especially considering the lightweight and easily deformable nature of insulation boards, the dual adsorption ensures stability during transfer without damaging the board, reducing material loss and safety risks during production.

[0016] 2. This invention utilizes an adjustment mechanism comprised of an electric cylinder, a rotating disk, an extension frame, and adjusting rods. By controlling the contraction and extension of the piston rod of the electric cylinder, the rotating disk is driven to rotate. Furthermore, through the cooperation of the straight slot of the extension frame and the positioning pin, the four adjusting rods are driven to simultaneously contract inward or extend outward, ultimately achieving flexible adjustment of the pneumatic suction cup's gripping range. This design breaks through the limitation of traditional stacking devices being "single-size adaptable," meeting the gripping needs of insulation boards of different lengths and widths. It eliminates the need for frequent fixture changes or equipment parameter adjustments, significantly improving the equipment's versatility in diverse production scenarios and reducing equipment investment costs for enterprises.

[0017] 3. This invention is equipped with a centering adjustment system consisting of a geared motor, worm gear, bevel gear transmission mechanism, and a centering plate. After the sheet material is placed in the stacking area, the geared motor drives the transmission components to move all the centering plates synchronously inward, precisely centering the sheet material in the stacking area. More importantly, this system has an "adaptive length-to-width ratio" adjustment capability: when the length-to-width ratio of the sheet material is different, the centering plate that first contacts the edge of the sheet material will automatically stop the rotation of the threaded rod through a structure of "driven bevel gear compressing the clamping spring, and round-headed pin engaging with the round hole slot," while the centering plates that have not contacted the sheet material can continue to move until longitudinal centering is completed. This design completely solves the problems of "sheet material misalignment and stacking tilt" in traditional stacking, significantly improving the neatness and stability of the stack, and providing convenience for subsequent warehousing and transportation.

[0027] 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. Example

[0028] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides an automatic stacking device for the production of insulation boards, such as... Figure 1As shown, the device includes a material-grabbing robot 1. As the core component for movement and positioning, the material-grabbing robot 1 can flexibly control the movement of the entire stacking device within space, enabling the transfer of the device from the insulation board storage area to the stacking area. It is a key actuator ensuring the continuity of the stacking operation process. A control chamber 2 is fixedly installed at the drive end of the material-grabbing robot 1. The control chamber 2 provides a closed installation space for the internal transmission components and control structure, protecting internal parts from external dust and impurities, while also providing support for the stable operation of each component. The reasonable layout of its internal structure directly affects transmission efficiency and adjustment accuracy. The bottom end of the control chamber 2 is fixedly installed at the top center of a square channel steel support 3. The square channel steel support 3, as the main load-bearing frame of the device, must not only withstand the insulation... The weight of the plate and each component also needs to provide an installation foundation for parts such as the adjusting rod 4 and the adsorption chamber 11. The channel steel material combines strength and lightweight characteristics, reducing the load pressure on the gripping robot 1 while ensuring structural stability. Adjusting rods 4 are movably installed at the four edges of the bottom of the square channel steel bracket 3 via limiting bushings. These limiting bushings constrain the movement direction of the adjusting rods 4, ensuring that they can only retract or expand horizontally, preventing deviation during adjustment. The adjusting rod 4 is a key component connecting the square channel steel bracket 3 and the pneumatic suction cup 5. It can adjust the position of the pneumatic suction cup 5 through its own extension and retraction. Pneumatic suction cups 5 are fixedly installed at the ends of the adjusting rods 4. The pneumatic suction cups 5 are the adsorption components that directly contact the insulation board, using their own... The adsorption force initially fixes the insulation board, forming a double fixing structure with the negative pressure adsorption of the adsorption chamber 11, effectively improving the stability of the insulation board during the transfer process. A rotating column 18 is movably installed inside the control chamber 2. The rotating column 18 can rotate around its own axis inside the control chamber 2. Its top end is fixedly connected to the driving bevel gear 19, and its bottom end is fixedly connected to the worm gear 31. It is the core shaft component for transmitting power, transmitting the rotational power of the worm gear 31 to the driving bevel gear 19. The driving bevel gear 19 is fixedly installed at the top of the rotating column 18. The driving bevel gear 19, through meshing with the surrounding driven bevel gears 22, synchronously transmits the rotational power of the rotating column 18 to multiple driven bevel gears 22, realizing the splitting and synchronous transmission of power, providing power for the synchronous rotation of the threaded rod 20. The power base consists of threaded rods 20 movably mounted on all four sides of the inner wall of the control chamber 2. These threaded rods 20 can rotate under the support of the inner wall of the control chamber 2. The threads on their outer walls engage with the internal threads of the movable block 27, converting their rotational motion into linear motion of the movable block 27, which in turn drives the extension rod 29 and the retracting plate 30 to move. Short shafts 21 are fixedly mounted on the inner ends of the threaded rods 20. One end of the short shaft 21 is fixed to the threaded rod 20, and the other end is fixed to the chuck 24. This allows the rotational power of the driven bevel gear 22 to be transmitted to the threaded rod 20, while also providing a mounting carrier for the compression spring 23 and the driven bevel gear 22. Driven bevel gears 22 are mounted on the outer diameter of the middle part of the short shaft 21, and the bottom ends of the driven bevel gears 22 are meshed with the top of the driving bevel gear 19.Driven bevel gear 22 obtains rotational power through meshing with driving bevel gear 19, and transmits the power to threaded rod 20 through short shaft 21. When the length-to-width ratio of the insulation board is different, the compression spring 23 can be used to achieve disengagement and engagement with chuck 24, preventing threaded rod 20 from rotating synchronously with it. Each threaded rod 20 has a threaded movable block 27 connected to its outer diameter. Driven by the rotation of threaded rod 20, movable block 27 can move linearly along the direction of limit guide rod 28. The extension rod 29 fixed at both ends can transmit its own movement to closing plate 30, connecting threaded rod 20 and closing plate 30. The key component, the movable block 27, has L-shaped extension rods 29 fixedly installed at both ends. These L-shaped extension rods 29 can change the direction of force transmission, extending the linear movement of the movable block 27 inside the control room 2 to the outside of the control room 2. This, in turn, drives the closing plate 30 to close the insulation panels in the stacking area. The ends of the extension rods 29 extend to the outside of the control room 2 and are fixedly installed with the closing plate 30. The closing plate 30 directly contacts the insulation panels in the stacking area, pushing them to the center of the stacking area through its inward movement. The closing range can be adaptively adjusted according to the size of the insulation panels to ensure the neatness and stability of the stacking.

[0029] In this embodiment, a rotating disk 6 is movably mounted on the middle of the bottom end of the square channel steel bracket 3 via a movable shaft. The movable shaft provides support and positioning for the rotation of the rotating disk 6, allowing the rotating disk 6 to rotate flexibly around the middle of the bottom end of the square channel steel bracket 3. The rotating disk 6 drives the extension frame 7 to move synchronously through its own rotation, and is the core component for power transmission in adjusting the position of the pneumatic suction cup 5. Four extension frames 7 are evenly fixedly mounted on the outer wall of the rotating disk 6. The four extension frames 7 are symmetrically distributed and can move synchronously under the drive of the rotating disk 6. The straight slots 8 opened inside each extension frame 7 cooperate with the positioning pins 9 of the adjusting rod 4, which can convert the rotational motion of the extension frame 7 into the linear motion of the adjusting rod 4. The straight slots 8 are opened inside each extension frame 7, and the straight slots 8 provide a movement channel for the positioning pins 9. When the extension frame 7 rotates, the positioning pins 9 can slide in the straight slots 8, thereby driving the adjusting rod 4 to retract or extend in the horizontal direction, realizing the adjustment of the position of the pneumatic suction cup 5. The bottom inner side of the adjusting rod 4 is fixedly equipped with positioning pins 9, and the ends of the positioning pins 9 extend into the corresponding straight grooves 8. One end of the positioning pin 9 is fixed to the adjusting rod 4, and the other end is embedded in the straight groove 8. It can transmit the movement of the extension frame 7 to the adjusting rod 4. It is a key connecting component connecting the extension frame 7 and the adjusting rod 4, ensuring that the adjusting rod 4 can move synchronously with the extension frame 7. An electric cylinder 10 is movably installed on one side of the bottom of the square channel steel bracket 3. The electric cylinder 10 provides power through the contraction and extension of its own piston rod, which can drive the rotating disk 6 to rotate around the movable axis. It is the power source for adjusting the position of the pneumatic suction cup 5. Its operation stability directly affects the adjustment accuracy of the adjusting rod 4. The end of the electric cylinder 10 is movably installed on the top side of the rotating disk 6. This installation method can smoothly convert the extension and retraction movement of the piston rod of the electric cylinder 10 into the rotational movement of the rotating disk 6, ensuring the smooth transmission of power and avoiding movement jamming.

[0030] Furthermore, weight-reducing through holes 17 are provided at the four corners of the square channel steel support 3. These through holes 17 reduce the weight of the support itself without compromising its structural strength, thus reducing the load on the material handling robot 1. Simultaneously, they provide installation space for the adsorption chamber 11, allowing it to be tightly fixed inside the square channel steel support 3. The adsorption chamber 11 is fixedly installed inside each of the weight-reducing through holes 17. The adsorption chamber 11 provides an installation cavity for the negative pressure chamber 12 and the negative pressure fan 13, protecting the internal negative pressure structure from external interference. Its bottom end contacts the insulation board, and the negative pressure of the negative pressure chamber 12 achieves adsorption of the insulation board, which is an important aspect of the dual adsorption structure. The adsorption chamber 11 is equipped with a negative pressure chamber 12 at its bottom. Under the action of the negative pressure fan 13, the negative pressure chamber 12 can form a strong negative pressure. The suction force generated by the negative pressure firmly adsorbs the insulation board to the bottom of the adsorption chamber 11. This, together with the adsorption force of the pneumatic suction cup 5, forms a double fixation, preventing the insulation board from falling off during transfer. The negative pressure fan 13 is fixedly installed in the middle of the adsorption chamber 11. The negative pressure fan 13 is the power source for generating negative pressure. When working, it can extract the air in the negative pressure chamber 12, so that the negative pressure chamber 12 forms a negative pressure. At the same time, the extracted air can be delivered to the nozzle 15 through the jet pipe 14 to achieve the cleaning function. Its operating efficiency directly affects the negative pressure adsorption effect and the cleaning effect.

[0031] Furthermore, each adsorption chamber 11 is fixedly installed with a jet pipe 14 at the top center. The jet pipe 14 serves as an air delivery channel, guiding the air drawn out by the negative pressure fan 13 to the nozzle 15. This ensures that the air is directionally delivered to the adsorption area of ​​the pneumatic suction cup 5, providing a guarantee for cleaning. The ends of the jet pipes 14 extend to one side of the corresponding pneumatic suction cup 5 and are fixedly installed with nozzles 15. The nozzles 15 can spray the air delivered by the jet pipes 14 in the form of a directional airflow, directly blowing on the adsorption area of ​​the pneumatic suction cup 5 to remove dust, debris, and other impurities from the surface of the insulation board, preventing impurities from affecting the adsorption sealing effect. Each adsorption chamber 11 is fixedly installed with a density rubber ring 16 on the outer side of its bottom end. The density rubber ring 16 has good sealing performance and elasticity. When the bottom end of the adsorption chamber 11 contacts the insulation board, the density rubber ring 16 can fill the gap between the adsorption chamber 11 and the insulation board, enhancing the sealing performance of the negative pressure chamber 12, ensuring that the negative pressure chamber 12 can maintain a stable negative pressure state, and improving the adsorption force.

[0032] Furthermore, a compression spring 23 is fixedly installed on the outer diameter of the short shaft 21 near the threaded rod 20, and the end of the compression spring 23 abuts against the outer end of the driven bevel gear 22 on the corresponding side. The compression spring 23 is always in a compressed state, which can apply pressure to the driven bevel gear 22 in the direction of the chuck 24 to ensure that the driven bevel gear 22 is tightly engaged with the round head pin 26 and the round hole groove 25 of the chuck 24. When needed, it can be compressed by the driven bevel gear 22 to achieve disengagement, providing conditions for the threaded rod 20 to stop rotating. The selection of its elastic coefficient directly affects the sensitivity of disengagement and engagement.

[0033] Furthermore, chucks 24 are fixedly installed on the outer diameter of the side of the short shaft 21 away from the threaded rod 20. The chucks 24 are fixedly connected to the short shaft 21 and can rotate synchronously with the short shaft 21. The round-headed pins 26 on their surfaces cooperate with the round-hole slots 25 of the driven bevel gear 22 to realize the transmission and cutting off of power. This is a key component for controlling whether the threaded rod 20 rotates with the driven bevel gear 22. Several round-hole slots 25 are opened on the inner side of the driven bevel gear 22. The round-hole slots 25 match the round-headed pins 26 of the chuck 24. When the round-headed pins 26 are inserted into the round-hole slots 25, the driven bevel gears... Wheel 22 can drive chuck 24 and short shaft 21 to rotate; when driven bevel gear 22 is under force, round hole groove 25 can disengage from round head pin 26 to achieve power cut-off. Several round head pins 26 are fixedly installed on one end of chuck 24 near driven bevel gear 22, and the ends of the round head pins 26 extend into the interior of the corresponding side round hole groove 25. The round head pins 26 have a smooth round head structure, which can flexibly disengage and engage in the round hole groove 25, reducing frictional resistance when disengaging, and ensuring that when the threaded rod 20 needs to stop rotating, the power separation between driven bevel gear 22 and chuck 24 can be quickly achieved.

[0034] Furthermore, limit guide rods 28 are fixedly installed on both sides of the inner wall of the control room 2, near each threaded rod 20. The limit guide rods 28 are arranged parallel to the threaded rods 20, which can constrain the movement direction of the movable block 27, prevent the movable block 27 from rotating with the threaded rod 20, and ensure that the movable block 27 moves only in a straight line. The accuracy of its installation position directly affects the movement accuracy of the movable block 27. The outer diameter of the limit guide rods 28 is movably installed on the inner sides of the corresponding movable block 27. This installation method allows the movable block 27 to slide smoothly along the limit guide rods 28. At the same time, the limit guide rods 28 can provide support for the movable block 27, preventing the movable block 27 from tilting or shaking during movement, and ensuring the stability of the movement of the extension rod 29 and the retracting plate 30.

[0035] Furthermore, a worm gear 31 is fixedly installed on the outer diameter of the middle part of the rotating column 18. The worm gear 31 is fixedly connected to the rotating column 18 and can rotate synchronously with the rotating column 18. Its meshing transmission with the worm 33 has the effect of speed reduction and torque increase, which can convert the high-speed rotation of the geared motor 32 into the low-speed stable rotation of the rotating column 18, ensuring that the driving bevel gear 19 can smoothly transmit power. A geared motor 32 is fixedly installed on one side of the control room 2. The geared motor 32 is the power source for driving the operation of the centering adjustment system and can provide stable rotational power. The worm 33 at its output end cooperates with the worm gear 31 to realize the transmission and speed reduction of power. By controlling the start, stop and direction of the geared motor 32, the movement of the closing plate 30 can be controlled. When stopped, the drive end of the geared motor 32 extends into the control room 2 and is fixedly installed with a worm gear 33. The worm gear 33 is fixedly connected to the drive end of the geared motor 32, which can transmit the power of the geared motor 32 to the worm wheel 31. The meshing structure between the worm gear 33 and the worm wheel 31 has a self-locking function, which can prevent the worm wheel 31 from rotating in the opposite direction when the geared motor 32 stops running, ensuring that the closing plate 30 can be kept in a fixed position. The inner end of the worm gear 33 is meshed with the inner end of the worm wheel 31. This meshing connection method can realize the vertical transmission of power, so that the horizontal output power of the geared motor 32 is converted into the vertical rotation power of the rotating column 18. At the same time, the transmission ratio of the worm wheel and worm gear is used to achieve deceleration, ensuring the stable operation of the centering adjustment system.

[0036] Working principle:

[0037] The device is moved to the location where the insulation board to be gripped is stored. The gripping robot 1 controls the square channel steel support 3 to move above the insulation board. When the four pneumatic suction cups 5 are about to approach the surface of the insulation board, the four negative pressure fans 13 are activated. The negative pressure fans 13 will extract the air from the negative pressure chamber 12, creating a strong negative pressure inside. At the same time, the extracted air is discharged through the jet pipe 14 and nozzle 15. The air sprayed from the nozzle 15 will blow the area that the pneumatic suction cups 5 need to adsorb, cleaning the dust and dirt on the surface of the board and improving the adsorption force of the pneumatic suction cups 5. Then, the gripping robot 1 continues to control the square channel steel support 3 to descend. The bottom of the pneumatic suction cups 5 and the adsorption chamber 11 simultaneously contact the surface of the insulation board. The strong negative pressure in the negative pressure chamber 12 will firmly adsorb the board. Simultaneously, the pneumatic suction cups 5 also adsorb and fix the insulation board. The double adsorption force firmly fixes the insulation board to the bottom of the square channel steel bracket 3, preventing the board from falling off during the transfer process. In addition, the retraction of the piston rod inside the electric cylinder 10 can be controlled to drive the rotating disk 6 to rotate. When the rotating disk 6 rotates, it will drive the four extension frames 7 on the outer wall to move accordingly. When the extension frames 7 move, they will drive the four adjusting rods 4 to retract inward or extend outward synchronously through the action of the straight groove 8 and the positioning pin 9, thereby causing the four pneumatic suction cups 5 to retract or extend accordingly, which facilitates the gripping of insulation boards of different sizes. After the gripping is completed, the gripping robot 1 moves the board to the stacking area and slowly lowers it. All negative pressure fans 13 and pneumatic suction cups 5 are turned off, and the board falls into the stack. Within the stacking area, the geared motor 32 is activated, driving the worm gear 33 to rotate. The rotating worm gear 33, through meshing transmission, drives the worm wheel 31 and the rotating column 18 to rotate, thereby driving the driving bevel gear 19 to rotate. When the driving bevel gear 19 rotates, it drives all the driven bevel gears 22 to rotate, which in turn drives all the short shafts 21 and the threaded rods 20 to rotate. When the threaded rods 20 rotate, the limiting guide rod 28 drives all the extension rods 29 and the closing plates 30 to move inward synchronously, thus closing the boards placed in the stacking area to the center position, thereby improving the stability of the board stacking. When the length-to-width ratio of the insulation boards is different, two opposite closing plates 30 will first contact the edge of the board, completing the lateral centering of the board. As the first plate closes, the other two closing plates 30 have not yet contacted the edge of the plate. At this time, the geared motor 32 continues to drive the worm gear 33 to rotate, and the driving bevel gear 19 will continue to drive all the driven bevel gears 22 to rotate, so that the two closing plates 30 that have not contacted the edge of the plate continue to move inward until the closing plate 30 contacts the edge of the plate and completes the longitudinal center closing. The threaded rods 20 of the two closing plates 30 that have previously contacted the plate will stop rotating. When the driven bevel gears 22 inside them rotate, they will compress the clamping spring 23, causing the round hole slot 25 and the round head pin 26 to continuously engage and disengage, thereby preventing the threaded rods 20 from rotating with the driven bevel gears 22. This achieves the closing of the plate to the center of the stacking area and improves the stacking stability.
