Description

Technical Field

[0001] The present application relates to the technical field of papermaking machinery, and in particular to an automatic pulp board supply system and method. Background Art

[0002] Paper is a sheet of fiber products used for writing, printing, painting or packaging. The traditional pulping process for pulp molding involves a series of carefully designed steps to ensure the quality of the final product. First, the required pulp sheets are accurately weighed and then soaked in water to soften the fibers. After sufficient water soaking, the pulp sheets are transferred to the beater. During the beating process, a strict 5% pulp-water ratio is followed to ensure the uniformity and consistency of the pulp. After the beating is completed, the resulting water slurry is transferred to the mixing tank, where waterproofing and oil-proofing agents are added in specific proportions to give the pulp waterproof and oil-proof properties. After these processing steps, in order to adapt to the needs of the production line, the water slurry needs to be diluted and adjusted to a water-slurry ratio of 0.4% to obtain a water slurry suitable for production. Finally, these treated water slurries are directly transferred to the supply tank to provide a continuous supply of pulp for the production line.

[0003] In order to further improve the efficiency and convenience of pulp use, the above-mentioned pulping system is generally designed and installed in the attic position, that is, the top floor of the factory building. This layout uses the effect of gravity to allow the prepared pulp to flow smoothly from the pulping system to the forming machine. In addition, in order to ensure the stable transportation of pulp, the system is also equipped with a pump to assist the pulp transportation process.

[0004] In the field of papermaking industry, raw material pulp board plays a vital role and is an indispensable part of the entire production process. Especially in the pulping process, a certain amount of raw material pulp board must be put in each time the pulping operation is carried out to ensure the smooth progress of the production process. Since the entire pulping process is completed in a high attic, this means that after the pulp board is purchased and transported to the factory, it must be lifted from the ground to the attic in some way and properly placed inside the pulper. This process currently involves a lot of manual operations, so it requires a lot of human resources to complete. In view of this, there is obvious room for improvement in this link, in order to reduce labor costs and improve production efficiency. Summary of the invention

[0005] In order to facilitate the supply of pulp boards, the present application provides an automatic pulp board supply system.

[0006] In the first aspect, the present application provides an automatic pulp board supply system adopting the following technical solution: A pulp board automatic supply system, comprising a loading mechanism, a traveling and hanging mechanism, a conveying mechanism, a unloading mechanism and a pulping machine, wherein the loading mechanism is used to convey the pulp boards stacked in piles from the ground to the attic, the loading mechanism comprises a lifting elevator and a receiving pallet, the receiving pallet is arranged on the lifting elevator and is used to place the pulp boards, and the lifting elevator controls the receiving pallet to move up and down in the vertical direction; One end of the traveling and hanging mechanism is close to the upper end of the lifting elevator, and the other end is close to the conveying mechanism. The traveling and hanging mechanism is used to transfer the pulp board on the receiving pallet to the conveying mechanism, and the traveling and hanging mechanism is located above the conveying mechanism; A lifting platform is provided at the conveying end of the conveying mechanism, and the lifting platform and the beater are arranged in sequence along the conveying direction of the conveying mechanism, and the lifting platform is used to lift the pulp board conveyed by the conveying mechanism; The unloading mechanism is used to transfer the pulp board on the lifting platform to the beater, and the unloading mechanism includes a baffle, a pushing assembly and a guide block. The baffle is arranged between the lifting platform and the beater, and the baffle is used to block the pulp board on the lifting platform; the pushing assembly is used to push the part of the pulp board exceeding the baffle into the beater, and the guide block is arranged on the side of the baffle facing the beater, and is used to guide the pulp board.

[0007] By adopting the above technical solution, during the production process, the staff first places the stacked pulp boards on the receiving pallet, and then uses the lifting motor to control the receiving pallet to move vertically upward, so as to lift the pulp boards from the ground to the attic.

[0008] Then the hoisting mechanism is operated, and the hoisting mechanism hoists the pulp board onto the conveying mechanism. Then the conveying mechanism is used to transport the pulp board to the lifting platform. The baffle can block the pulp board and prevent the pulp board from falling directly from the lifting platform into the beater.

[0009] When unloading, the pusher assembly is operated to push the topmost pulp board toward the beater, and the part of the pulp board that exceeds the baffle will fall into the beater along the guide block. The height of the pulp board is adjusted by the lifting platform. After the pusher assembly completes one push, the lifting platform is controlled to rise to a certain height so that the pulp board can be pushed into the beater again by the pusher assembly, and so on and so forth until all the pulp boards are completely dropped into the beater, thus achieving dispersed unloading. The entire pulp board supply process is highly automated and does not require excessive reliance on manual labor, thus reducing the labor intensity of personnel.

[0010] The reason why the pulp sheets need to be dispersed and fed is, on the one hand, to avoid a large number of pulp sheets falling into the beater at the same time and splashing water, and on the other hand, a small amount of pulp sheets can be fully crushed and dissociated after entering the beater, thereby improving the beating effect.

[0011] Preferably, the conveying mechanism includes a support seat, a first conveying roller and a second conveying roller, a plurality of first conveying rollers are provided, and all of them are rotatably connected to the support seat, and each of the first conveying rollers forms a first conveying surface, and the first conveying surface is inclined upward in a direction close to the lifting platform; a plurality of second conveying rollers are provided, and all of them are rotatably connected to the support seat, and each of the second conveying rollers forms a second conveying surface, and the second conveying surface is located between the lifting platform and the first conveying surface and is horizontally arranged, and the first conveying surface and the second conveying surface are both used for conveying the pulp board.

[0012] By adopting the above technical solution, the support seat is used as a carrier, and the hoisting mechanism will first place the pulp board on the first conveying roller. Under the conveying action of the first conveying roller, the pulp board will gradually raise its position and approach the second conveying roller. Then, under the conveying action of the second conveying roller, the pulp board will be transported to the lifting platform. Although the pulp board will have inertia, the presence of the baffle can prevent the pulp board from falling from the lifting platform.

[0013] Preferably, the pushing assembly includes a driving member and a pushing plate, the pushing plate is movably arranged and is located above the baffle, the pushing plate is used to push the pulp plate on the lifting platform, and the driving member is connected to the pushing plate and is used to control the linear movement of the pushing plate.

[0014] By adopting the above technical solution, when pushing the material, the driving member is operated, and the driving member controls the push plate to move in the direction close to the beater. The movement of the push plate can push a part of the pulp plate to the material guide block, and then fall into the beater.

[0015] Preferably, it also includes a frame, the lifting platform is slidably connected to the frame, a slide groove is opened on the frame in the vertical direction, a rolling wheel is rollingly connected in the slide groove, a fixed seat is connected to the bottom of the lifting platform, and the fixed seat is connected to the rolling wheel; a plurality of rollers are connected to the lifting platform, each of the rollers forms a support plane, and the support plane is used to support the pulp board.

[0016] By adopting the above technical solution, when the fixed seat and the lifting platform rise, the rolling wheel will roll in the slide groove, and the force of rolling friction is smaller than that of sliding friction, which can improve the stability and smoothness of the fixed seat and the lifting platform when they are raised and lowered.

[0017] The rollers on the lifting platform can achieve rolling friction in contact with the lower surface of the pulp board, thereby reducing the friction force of the pulp board when it moves on the lifting platform and reducing the damage to the pulp board.

[0018] Preferably, a scissor-type lift is provided below the fixing seat, and the scissor-type lift is used to control the synchronous lifting of the fixing seat and the lifting platform.

[0019] By adopting the above technical solution, a scissor-type lift is a common device used to drive lifting. By relying on the scissor-type lift, the fixed seat can be controlled to move up and down on the frame to realize the lifting and lowering of the lifting platform.

[0020] Preferably, the cross-section of the slide groove is U-shaped, and the rolling wheel includes a first wheel, a second wheel, a third wheel, a fourth wheel, a fifth wheel, a first connecting shaft, a second connecting shaft and a third connecting shaft. The first wheel and the second wheel are coaxially arranged and connected by the first connecting shaft, and the first wheel and the second wheel can be rotatably connected to the first connecting shaft; the third wheel and the fourth wheel are coaxially arranged and connected by the second connecting shaft, and the third wheel and the fourth wheel can be rotatably connected to the second connecting shaft; both ends of the third connecting shaft are respectively connected to the first connecting shaft and the second connecting shaft, and the fifth wheel is rotatably connected to the third connecting shaft.

[0021] By adopting the above technical solution, when the fixed seat moves, the first wheel, the second wheel, the third wheel, the fourth wheel and the fifth wheel will all rotate in the slide groove, relying on multi-point contact to improve the stability of the rolling wheel when rolling in the slide groove.

[0022] Preferably, it also includes a pneumatic cylinder, and one end of the lifting platform close to the beater is rotatably connected to the fixed seat, the bottom of the lifting platform is connected with a sliding rod, and a slider is slidably connected to the sliding rod. The pneumatic cylinder is arranged on the fixed seat, and the piston rod of the pneumatic cylinder is hinged to the slider and is used to control the slider to slide on the sliding rod, and the slider is tangent to the lower end of the roller.

[0023] By adopting the above technical solution, when only a small part of the pulp plate on the lifting platform exists, the rotating end of the lifting platform is controlled to be flush with or slightly higher than the upper end of the baffle, and then the pneumatic cylinder is operated, and the piston rod of the pneumatic cylinder is extended. Since the piston rod and the slider are hinged, the angle between the piston rod and the slider will change adaptively, so that the slider moves on the slide rod in the direction away from the baffle side, thereby realizing a certain rotation of the lifting platform, that is, the end of the lifting platform close to the baffle is lower, and the end away from the baffle is higher. Under the gravity component force, the pulp plate of the lifting platform will fall to the guide block and then enter the beater.

[0024] Among them, when the slider moves along the slide rod, since the slider is tangent to some rollers, the movement of the slider will drive these rollers to rotate in the counterclockwise direction. The rotation of the rollers plays an auxiliary feeding role to a certain extent, that is, it will generate a conveying force on the pulp board. The conveying force and the gravity component force are superimposed, which makes it easier for the pulp board to fall into the beater.

[0025] Preferably, it also includes a gas spring and an interception plate, wherein the interception plate is rotatably connected to the lower end of the guide block and is used to intercept the falling pulp plate, and the gas spring is connected to the interception plate and is used to control the rotation of the interception plate.

[0026] By adopting the above technical solution, since there is a certain height between the horizontal plane where the upper end of the baffle plate is located and the horizontal plane where the feed port of the beater is located, gravity acceleration will be generated in the process of the pulp plate falling along the guide block. The pulp plate rushes into the beater at a certain speed, in which case there is a certain possibility of causing the slurry to splash out. By adding an intercepting plate and a gas spring, the intercepting plate can block the pulp plate that slides down from the guide block and reduce its speed to 0; then the gas spring controls the intercepting plate to rotate, and the pulp plate will gradually fall into the beater along the intercepting plate, thereby reducing the initial velocity of the pulp plate when entering the beater, and further reducing the possibility of slurry splashing out.

[0027] Preferably, it further comprises a guide rod, wherein the guide rod is arranged along the moving direction of the push plate, and the push plate is slidably connected to the guide rod.

[0028] By adopting the above technical solution, the guide rod can play a guiding and limiting role in the movement of the push plate, thereby improving the stability and accuracy of the push plate during movement.

[0029] In a second aspect, the present application further provides a method for automatically supplying a pulp board, which uses an automatic pulp board supply system having all the above structures, and includes the following steps: S1. The staff puts the stacked pulp boards on the receiving pallet, and the lifting elevator lifts the receiving pallet from the ground to the loft; S2, then operate the traveling and lifting mechanism, the traveling and lifting mechanism lifts the pulp board onto the conveying mechanism, and uses the conveying mechanism to convey the pulp board to the lifting platform, and the baffle is used to block the pulp board; S3. The height of the pulp board is adjusted through the lifting platform. When unloading, the pushing assembly is operated to push the uppermost pulp board toward the beater. The part of the pulp board that exceeds the baffle will fall into the beater along the guide block to achieve dispersed unloading.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting up a loading mechanism, a crane mechanism, a conveying mechanism, a unloading mechanism and a beater, during the production process, the staff first places the stacked pulp boards on the receiving pallet, and then controls the receiving pallet to rise vertically through the lifting motor, thereby lifting the pulp boards from the ground to the attic. Next, the crane mechanism is started to lift the pulp boards to the conveying mechanism. Subsequently, the conveying mechanism transports the pulp boards to the lifting platform. The function of the baffle is to block the pulp boards and prevent them from falling directly from the lifting platform into the beater. During the unloading process, the pusher assembly is started to push the top layer of pulp boards toward the beater, and the pulp boards that exceed the baffle will slide into the beater along the guide block. The height of the pulp boards is adjusted by the lifting platform. Each time the pusher assembly completes pushing, the lifting platform will rise accordingly to ensure that the pulp boards can continue to be pushed into the beater until all the pulp boards are dispersed and unloaded. The entire pulp board supply process is highly automated, which greatly reduces the dependence on manual labor and effectively reduces the labor intensity of workers.

[0031] (2) By setting up a scissor-type lift, the fixed seat can be controlled to move up and down on the frame to realize the lifting and lowering of the lifting platform.

[0032] (3) By setting up a gas spring and an intercepting plate, the function of the intercepting plate is to intercept the pulp plate sliding down from the guide block and make its speed drop suddenly to zero; through the control of the gas spring, the intercepting plate can rotate, so that the pulp plate gradually slides into the beater along the intercepting plate, thereby reducing the initial speed of the pulp plate when entering the beater, and effectively reducing the probability of slurry splashing.

[0040] The present application embodiment discloses an automatic pulp board supply system. Figure 1 and Figure 2 The automatic pulp board supply system includes a loading mechanism 1, a traveling hoisting mechanism 2, a conveying mechanism 3, a unloading mechanism 4 and a beater 5. The loading mechanism 1 is used to transport the stacked pulp boards from the ground to the attic. The loading mechanism 1 includes a lifting elevator 11 and a receiving pallet 12. The receiving pallet 12 is horizontally installed on the lifting elevator 11 and is used to place the pulp boards. The lifting elevator 11 is used to control the receiving pallet 12 to move up and down in the vertical direction, thereby realizing the transportation and transfer of the pulp boards. One end of the traveling hoisting mechanism 2 is close to the upper end of the lifting elevator 11, and the other end is close to the conveying mechanism 3 and is above the conveying mechanism 3. The traveling hoisting mechanism 2 is used to horizontally transfer the pulp boards on the receiving pallet 12 to the conveying mechanism 3. The traveling hoisting mechanism 2 belongs to conventional technology, and the existing traveling hoisting equipment can be directly applied to this embodiment. Among them, a lifting platform 6 is installed at the conveying end of the conveying mechanism 3, and the lifting platform 6 is used to lift the pulp boards conveyed by the conveying mechanism 3.

[0041] Reference Figure 3 Specifically, the conveying mechanism 3 includes a support seat 31, a first conveying roller 32 and a second conveying roller 33. The support seat 31 is installed on the ground. A plurality of first conveying rollers 32 are arranged in parallel and can be rotatably connected to the support seat 31. Each first conveying roller 32 forms a first conveying surface, and the first conveying surface is inclined upward in a direction away from the traveling crane mechanism 2. A plurality of second conveying rollers 33 are arranged in parallel and can be rotatably connected to the support seat 31. Each second conveying roller 33 forms a second conveying surface, which is arranged horizontally and located between the lifting platform 6 and the first conveying surface. Both the first conveying surface and the second conveying surface are used to convey the pulp board. The first conveying surface lifts the pulp board upward, and the second conveying surface conveys the pulp board horizontally to the lifting platform 6.

[0042] A scissor lift 7 is mounted on the support seat 31, and a fixed seat 8 is connected to the bottom of the lifting platform 6. The fixed seat 8 is connected to the scissor lift 7, and the scissor lift 7 is used to control the synchronous lifting of the fixed seat 8 and the lifting platform 6. A plurality of rollers 9 are rotatably connected to the lifting platform 6, and the rotating shaft of the roller 9 is parallel to the rotating shaft of the second conveying roller 33. Each roller 9 forms a supporting plane, which is horizontally arranged and used to support the pulp board.

[0043] Combination Figure 4The beater 5 is located on one side of the lifting platform 6, and the unloading mechanism 4 is used to transfer the pulp board on the lifting platform 6 to the beater 5. The unloading mechanism 4 includes a baffle 41, a push assembly 42 and a guide block 43. The baffle 41 is located between the lifting platform 6 and the beater 5 and is fixedly connected to the support seat 31; the baffle 41 is vertically arranged to block the pulp board on the lifting platform 6.

[0044] The push assembly 42 is used to push the portion of the pulp plate that exceeds the upper end of the baffle 41 into the beater 5. The push assembly 42 includes a driving member 421 and a push plate 422. The push plate 422 is horizontally movably arranged and is located above the baffle 41. The push plate 422 is used to push the pulp plate on the lifting platform 6. The driving member 421 is connected to the push plate 422 and is used to control the linear movement of the push plate 422. The driving member 421 is a cylinder, an oil cylinder or an electric push rod. In this embodiment, the driving member 421 is a cylinder, and the piston rod of the cylinder is connected to the push plate 422. When the piston rod of the cylinder controls the push plate 422 to move in the direction close to the beater 5, the push plate 422 will push part of the pulp plate to the guide block 43, and then fall into the beater 5. Among them, a plurality of guide rods 10 are also horizontally installed above the lifting platform 6. The guide rods 10 are arranged along the moving direction of the push plate 422, and the push plate 422 is slidably connected to the guide rods 10. The guide rod 10 can guide and limit the movement of the push plate 422, thereby improving the stability and accuracy of the push plate 422 during movement.

[0045] The guide block 43 is installed on the side of the baffle 41 close to the beater 5, and is used to guide the pulp board so that the pulp board falls into the beater 5. The guide block 43 is a right-angled triangle block, and the inclined surface of the guide block 43 serves as a guide surface. Figure 5 The guide block 43 is also provided with a gas spring 14 and an intercepting plate 13. The intercepting plate 13 is rotatably connected to the guide block 43 and is close to the beater 5. The plane where the intercepting plate 13 is located and the guide surface of the guide block 43 form an angle. The intercepting plate 13 is used to intercept the pulping plate falling from the guide block 43. The gas spring 14 is connected to the intercepting plate 13 to control the rotation of the intercepting plate 13.

[0046] Due to the height difference between the upper end of the baffle 41 and the feed port of the beater 5, the pulp board will be affected by the acceleration of gravity when falling along the guide block 43. When the pulp board rushes into the beater 5 at a certain speed, it may cause the slurry to splash out. In order to solve this problem, the process is optimized by adding an interception plate 13 and a gas spring 14. The interception plate 13 can effectively block the pulp board that slides off the guide block 43 and reduce its speed to zero; then, the gas spring 14 drives the interception plate 13 to rotate, so that the pulp board gradually falls into the beater 5 along the interception plate 13, which not only reduces the initial speed of the pulp board when entering the beater 5, but also further reduces the possibility of slurry splashing out.

[0047] According to some embodiments of the present application, optionally, please refer to Figure 6 and Figure 7 A frame 15 is also installed on one side of the support seat 31, and the fixed seat 8 is slidably connected to the frame 15. A slide groove 16 is provided on the frame 15 in the vertical direction, and the number of the slide grooves 16 is four, and each slide groove 16 is parallel to each other. A rolling wheel 17 is rollingly connected in the slide groove 16, and the fixed seat 8 is connected to the rolling wheel 17. When the fixed seat 8 and the lifting platform 6 rise, the rolling wheel 17 will roll in the slide groove 16, and the force of rolling friction is smaller than that of sliding friction, which can improve the stability and smoothness of the fixed seat 8 and the lifting platform 6 when they are lifted.

[0048] In this embodiment, the cross section of the slide groove 16 is U-shaped. Specifically, the rolling wheel 17 includes a first wheel 171, a second wheel 172, a third wheel 173, a fourth wheel 174, a fifth wheel 175, a first connecting shaft 176, a second connecting shaft 177 and a third connecting shaft 178. The first wheel 171 and the second wheel 172 are coaxially arranged and connected by the first connecting shaft 176. The first wheel 171 and the second wheel 172 can both be rotatably connected to the first connecting shaft 176, and the first connecting shaft 176 is the rotating shaft of the first wheel 171 and the second wheel 172. The third wheel 173 and the fourth wheel 174 are coaxially arranged and connected by the second connecting shaft 177. The third wheel 173 and the fourth wheel 174 can both be rotatably connected to the second connecting shaft 177. The second connecting shaft 177 serves as the rotating shaft of the third wheel 173 and the fourth wheel 174, and the second connecting shaft 177 and the first connecting shaft 176 are parallel to each other. The two ends of the third connecting shaft 178 are respectively connected to the first connecting shaft 176 and the second connecting shaft 177. The third connecting shaft 178 is perpendicular to the first connecting shaft 176. The fifth wheel 175 is rotatably connected to the third connecting shaft 178, and the third connecting shaft 178 serves as the rotating shaft of the fifth wheel 175. The fixing seat 8 is connected to the third connecting shaft 178, and the first wheel 171, the second wheel 172, the third wheel 173, the fourth wheel 174, and the fifth wheel 175 are all tangent to the slide groove 16, so that the rolling wheel 17 and the frame 15 can be contacted at multiple points.

[0049] In addition, in some embodiments, please refer to Figure 8 , one end of the lifting platform 6 close to the baffle 41 is rotatably connected to the fixed seat 8, and a slide bar 18 is fixedly connected to the bottom of the lifting platform 6, and the slide bar 18 is arranged along the conveying direction of the second conveying surface. A slider 19 is slidably connected to the slide bar 18, and a pneumatic cylinder 20 is also installed in the middle of the fixed seat 8. The pneumatic cylinder 20 is located below the slider 19. The piston rod of the pneumatic cylinder 20 is hinged to the slider 19 and is used to control the slider 19 to move along the slide bar 18. When the slider 19 moves on the slide bar 18 in a direction away from the baffle 41, the lifting platform 6 will rotate. Among them, the slider 19 is tangent to the lower end of the roller 9, and the upper end of the slider 19 and the lower end surface of each roller 9 are in the same plane.

[0050] When the number of pulp plates on the lifting platform 6 is reduced to only a small number, the rotating end of the lifting platform 6 can be controlled to be flush with or slightly higher than the upper end of the baffle 41. Then the pneumatic cylinder 20 is started, and the piston rod in the cylinder will extend. Since the piston rod and the slider 19 are connected by a hinge, the extension of the piston rod will cause the angle between the slider 19 and the piston rod to be adaptively adjusted, thereby causing the slider 19 to move along the slide rod 18 to the side away from the baffle 41. This action causes the lifting platform 6 to rotate to a certain extent, that is, the end close to the baffle 41 is at a lower position, while the end away from the baffle 41 is at a higher position. Under the action of gravity, the pulp plates on the lifting platform 6 will slide toward the guide block 43 and eventually enter the beater 5.

[0051] At the same time, when the slider 19 moves on the slide bar 18, due to contact with some rollers 9, the movement of the slider 19 causes these rollers 9 to rotate counterclockwise. The rotation of the rollers 9 assists the feeding process to a certain extent, providing additional conveying force for the pulp sheet. This conveying force combined with the gravity component force helps the pulp sheet to fall into the beater 5 more smoothly.

[0052] The implementation principle of an automatic pulp board supply system in an embodiment of the present application is as follows: during the production process, the staff first places the stacked pulp boards on a receiving pallet 12, and then uses a lifting motor to control the receiving pallet 12 to move vertically upward, so as to lift the pulp boards from the ground to the attic.

[0053] Then the hoisting mechanism 2 is operated, and the hoisting mechanism 2 hoists the pulp board onto the conveying mechanism 3. Then the conveying mechanism 3 is used to convey the pulp board to the lifting platform 6. The baffle 41 can block the pulp board to prevent the pulp board from falling directly from the lifting platform 6 into the beater 5.

[0054] When unloading, the pusher assembly 42 is operated to push the uppermost pulp board toward the direction of the beater 5, and the portion of the pulp board that exceeds the baffle 41 will fall into the beater 5 along the guide block 43. The height of the pulp board is adjusted by the lifting platform 6. After the pusher assembly 42 completes one push, the lifting platform 6 is controlled to rise to a certain height so that the pulp board can be pushed into the beater 5 again by the pusher assembly 42, and so on and so forth until all the pulp boards are completely dropped into the beater 5, thus realizing dispersed unloading. The entire pulp board supply process has a high degree of automation, does not need to rely too much on manual labor, and reduces the labor intensity of personnel.

[0055] The reason why the pulp sheets need to be dispersed and discharged is, on the one hand, to prevent a large number of pulp sheets from falling into the beater 5 at the same time and splashing water, and on the other hand, a small amount of pulp sheets can be fully crushed and dissociated after entering the beater 5, thereby improving the beating effect.

[0056] Based on the above embodiment, the embodiment of the present application further provides a method for automatically supplying pulp boards, which uses the entire structure of the above automatic pulp board supply system to supply pulp boards, including the following steps: S1. The staff places the stacked pulp boards on the receiving pallet 12, and then the lifting elevator 11 hoists the receiving pallet 12 from the ground to the attic; S2, then operate the traveling and lifting mechanism 2, the traveling and lifting mechanism 2 hoists the pulp board onto the conveying mechanism 3, and the conveying mechanism 3 conveys the pulp board to the lifting platform 6, the baffle 41 is used to block the pulp board to prevent the pulp board from directly falling from the lifting platform 6 into the beater 5; S3. The pulp board is adjusted to an appropriate height through the lifting platform 6. When unloading, the pushing assembly 42 is started to push the top pulp board toward the beater 5. The part of the pulp board that exceeds the baffle 41 slides along the guide block 43 into the beater 5. Each time the pushing assembly 42 completes pushing, the lifting platform 6 will rise accordingly to ensure that the pulp board can continue to be pushed into the beater 5 until all the pulp boards are dispersed and unloading is completed, thereby realizing dispersed unloading.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
