Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PP plate, more specifically, it relates to a continuous carrying and stacking device for PP plate production and a working method. BACKGROUND

[0002] PP plate (polypropylene plate) is a kind of thermoplastic plate made of polypropylene as the main raw material, which has the characteristics of light weight, corrosion resistance, easy processing, etc., and is widely used in industrial, construction, advertising, packaging and other fields.

[0003] In the prior art, PP plates can be divided into various types according to their internal structures; solid PP plates have high strength and rigidity, and are suitable for occasions with high load-bearing requirements; honeycomb PP plates have a honeycomb structure inside, have good compression resistance and sound and heat insulation performance, and are often used in applications with high lightweight requirements; corrugated PP plates have a wavy surface structure, and are often used for building exterior walls, roof materials, etc.; multi-layer composite PP plates are composed of multiple layers of PP materials or other materials with different properties, which enhances wear resistance, flame resistance, thermal insulation, etc.

[0004] Among them, the last step in the production of honeycomb PP plates is carrying and stacking, and the stacked honeycomb PP plates can form a stable stacking structure, which is convenient for overall carrying and transportation by using forklifts, pallet trucks and other equipment.

[0005] The carrying and stacking of existing honeycomb PP plates is generally carried out by workers using forklifts or manual carrying tools to carry the honeycomb PP plates to the designated position and stack them; however, since the honeycomb core of the honeycomb PP plate has poor lateral compression resistance, when two stacks of honeycomb PP plates are in close contact, the lateral contact surfaces will exert pressure on each other, and the honeycomb core cannot effectively resist this lateral extrusion, resulting in compression deformation of the core layer, and further causing the two stacks of honeycomb PP plates to "lean together" (both inclined to the middle). This inclination not only destroys the neatness and stability of the stack, but also may cause damage to the honeycomb PP plates during subsequent carrying and use.

[0006] In addition, since the lightweight of the honeycomb PP plate depends on the hollow structure, the longitudinal bending stiffness is low (especially for long plates), and when the stacking height of the honeycomb PP plates is high, elastic or plastic bending deformation is easy to occur under continuous pressure. This deformation will cause the middle part of the honeycomb PP plate to sink due to the loss of support, while the four corners will be raised due to the relatively complete edge structure; this phenomenon not only affects the appearance quality of the plate, but also may cause further damage during transportation and use, and even affect the normal use of the product.

[0007] Therefore, the present application proposes a continuous carrying and stacking device for PP plate production and a working method to improve the existing problems. SUMMARY

[0017] The application is further provided that: the pressing member comprises a first support, a first gear rotatably connected in the first support, a second support arranged at one side of the first gear, a second gear rotatably connected in the second support, a chain sleeved on the first gear and the second gear, rotating plates symmetrically rotatably connected on the two sides of the first support, an adjusting cylinder arranged at the side of the rotating plate away from the first support, a spring rotatably connected at the expansion end of the adjusting cylinder, and a pressing plate arranged at the end of the second support away from the second support; the end of the first support away from the first gear is connected to the bottom of the partition plate, the end of the rotating plate away from the first support is rotatably connected to the corresponding side wall of the second support, the end of the adjusting cylinder away from the spring is rotatably connected to the bottom of the partition plate, and the end of the spring away from the adjusting cylinder is connected to the side wall of the corresponding rotating plate.

[0018] The continuous carrying and stacking method for PP plate production uses the continuous carrying and stacking device for PP plate production as described above, and comprises the following steps: S1. Before stacking the honeycomb PP panels, the drive cylinder is started first, pushing the drive plate to move upward, so that the separators open at equal intervals, and the corresponding separators open at equal intervals at the same time, so that the spacing between each separator is equal, and the stacking of the honeycomb PP panels is layered to bear the load, so as to distribute the pressure of the bottom layer of the honeycomb PP panels. S2. When stacking honeycomb PP panels, the honeycomb PP panels on one side are transported and stacked by a set of handling units, while the honeycomb PP panels on the other side are transported and stacked by another set of handling units. This allows the honeycomb PP panels on one side to be stacked on one side of the anti-tipping unit and on the corresponding partition plate, while the honeycomb PP panels on the other side of the anti-tipping unit are stacked on the other corresponding partition plate. This allows the anti-tipping unit to provide spaced support for the honeycomb PP panels on both sides. S3. When the honeycomb PP panels on both sides are stacked at the same time, the telescopic cylinder is activated. Its telescopic end pushes the slider and the adjusting part to move downward at the same time, so that the two racks move downward synchronously, thereby driving several rotating gears to rotate and flipping the corresponding lifting parts. During the flipping process, the lifting parts lift the corresponding honeycomb PP panels and insert them into the bottom of the corresponding honeycomb PP panels. S4. During the operation of S3, the lifting component will also be activated to provide arch support for the bottom layer of honeycomb PP panels stacked on each partition board, so that the middle part of the honeycomb PP panels is lifted upwards; at the same time, the pressing component will also be activated to press down the four corners of the top layer of honeycomb PP panels stacked on each partition board, so that the four corners of the honeycomb PP panels no longer lift up, thereby making the honeycomb PP panels stacked on each partition board more flat.

[0019] In summary, this application includes at least one of the following beneficial technical effects: (1) Through the design of the anti-tipping unit, on the one hand, it can provide spaced support for the honeycomb PP panels stacked on both sides, and on the other hand, it can lift the honeycomb PP panels stacked on both sides and insert them into the bottom of the corresponding honeycomb PP panels, so that the honeycomb PP panels stacked on both sides are kept horizontally stacked. This avoids the fact that the honeycomb core of the honeycomb PP panel has extremely poor lateral compressive strength. When the two stacks of honeycomb PP panels are close together, the lateral contact surfaces will exert pressure on each other, and the honeycomb core cannot effectively resist this lateral compression, which leads to core layer compression deformation, and then the problem of the two stacks of honeycomb PP panels "tilting towards each other" (tilting towards the middle at the same time) occurs. This ensures the quality of the honeycomb PP panels and is conducive to the neatness and stability of the honeycomb PP panel stacking.

[0020] (2) Through the design of anti-collapse unit, the stacking of honeycomb PP panels can be layered to bear the load, so as to disperse the pressure of the bottom layer of honeycomb PP panels.

[0021] (3) Through the anti-collapse unit design, the honeycomb PP board with the middle collapsed and the four corners raised can be supported by arched upwards and pressed down by the four corners at the same time. This makes the honeycomb PP board stacked on each layer of partition board more flat, avoiding the problem that when the stacking height of the honeycomb PP board is high, it is easy to undergo elastic or plastic bending deformation under continuous pressure. This deformation will cause the middle part of the honeycomb PP board to sink due to loss of support, while the four corners will be raised due to the relatively complete edge structure. This ensures the appearance quality of the honeycomb PP board, which is beneficial to the subsequent use of the honeycomb PP board. Attached Figure Description

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0038] Please see Figures 1-14 The present invention provides the following technical solutions: Example 1, see Figures 1-14 A continuous handling and stacking device for PP sheet production includes two handling units 1, an anti-tipping unit 2 between the two handling units 1, and anti-collapse units 3 symmetrically arranged on both sides of the anti-tipping unit 2.

[0039] The anti-tipping unit 2 serves two purposes: firstly, it provides spaced support for the stacked honeycomb PP panels on both sides; secondly, it lifts the stacked honeycomb PP panels on both sides and inserts them under the corresponding honeycomb PP panels, ensuring that the stacked honeycomb PP panels on both sides are horizontally stacked. This avoids the problem that the honeycomb core of the honeycomb PP panels has extremely poor lateral compressive strength. When two stacks of honeycomb PP panels are close together, the lateral contact surfaces will exert pressure on each other, and the honeycomb core cannot effectively resist this lateral compression, resulting in core layer compression deformation. This leads to the problem of the two stacks of honeycomb PP panels "tilting" (simultaneously tilting towards the middle), thus ensuring the quality of the honeycomb PP panels and contributing to the neatness and stability of the honeycomb PP panel stack.

[0040] The anti-collapse unit 3 serves two purposes: firstly, it can distribute the pressure on the bottom layer of the honeycomb PP panels by layering the stacked panels; secondly, it can simultaneously provide arched support to lift the honeycomb PP panels that have collapsed in the middle or raised at the four corners, and press the four corners down. This ensures that the honeycomb PP panels stacked on each layer of partition plate 35 have a high degree of flatness, avoiding the problem of elastic or plastic bending deformation that can easily occur under continuous pressure when the stacking height of the honeycomb PP panels is high. Such deformation would cause the middle part of the honeycomb PP panels to sink due to loss of support, while the four corners would rise due to the relatively intact edge structure. This ensures the appearance quality of the honeycomb PP panels, which is beneficial to their subsequent use.

[0041] See Figures 1-4 Specifically, the handling unit 1 includes a roller conveying mechanism 11, a transverse conveying mechanism 12 disposed below the roller conveying mechanism 11, a first lifting cylinder 13 symmetrically disposed at the bottom of the transverse conveying mechanism 12, a base 14 disposed between the roller conveying mechanisms 11, a second lifting cylinder 15 disposed at the top of the base 14, a snap-fit ​​plate 16 disposed at the telescopic end of the second lifting cylinder 15, and a logistics pallet 17 disposed at the top of the snap-fit ​​plate 16; the conveying directions of the roller conveying mechanism 11 and the transverse conveying mechanism 12 are perpendicular to each other; a guide rail 18 is also disposed at the top of the logistics pallet 17, a guide plate 19 is slidably disposed on the guide rail 18, and a support box 21 is located at the top of the guide plate 19.

[0042] In this process, when stacking honeycomb PP panels, one side of the honeycomb PP panels is transported and stacked by a set of transport units 1, while the other side of the honeycomb PP panels is transported and stacked by another set of transport units 1. This allows the honeycomb PP panels on one side to be stacked on one side of the anti-tipping unit 2 and on the corresponding partition plate 35, while the honeycomb PP panels on the other side of the anti-tipping unit 2 are stacked on the other corresponding partition plate 35. This allows the anti-tipping unit 2 to provide spaced support for the honeycomb PP panels on both sides.

[0043] The roller conveyor 11 conveys the honeycomb PP board along the axial direction M, and the transverse conveyor 12 conveys the honeycomb PP board along the radial direction N. During this process, the first lifting cylinder 13 is activated, which can drive the transverse conveyor 12 to lift and lower. When the honeycomb PP board is conveyed above the transverse conveyor 12, it can be conveyed to the logistics pallet 17 for stacking by the transverse conveyor 12.

[0044] It should be noted that the roller conveyor mechanism 11 and the transverse conveyor mechanism 12 have all the parts and drives for conveying, which will not be described in detail here.

[0045] The guide plate 19 is an electric slider. It is activated by the guide plate 19 and slides on the guide rail 18, so that the anti-rollover unit 2 slides synchronously. This is beneficial to the flexibility of the anti-rollover unit 2. At the same time, multiple sets of guide plates 19 and multiple sets of anti-rollover units 2 can be set on the guide rail 18, which is beneficial to the side support of the long honeycomb PP board.

[0046] At the same time, by activating the second lifting cylinder 15, the snap-fit ​​plate 16 and the logistics pallet 17 can be raised and lowered along with the stacking of the honeycomb PP panels.

[0047] See Figures 5-11 Specifically, the anti-rollover unit 2 includes a support box 21, a telescopic cylinder 22 disposed on the top of the support box 21, a slider 23 disposed on the telescopic end of the telescopic cylinder 22, an adjusting member 24 disposed on one side of the slider 23, a rack 25 disposed on both ends of the adjusting member 24, a rotating gear 26 evenly disposed on one side of the rack 25, and a lifting member 27 disposed on one end of the rotating gear 26.

[0048] When the honeycomb PP panels on both sides are stacked simultaneously, the telescopic cylinder 22 is activated. Its telescopic end pushes the slider 23 and the adjusting component 24 to move downwards simultaneously, thereby causing the two racks 25 to move downwards synchronously. This, in turn, drives several rotating gears 26 to rotate and flips the corresponding lifting component 27 90 degrees. During the flipping process, the lifting component 27 lifts the corresponding honeycomb PP panel and inserts it under the corresponding honeycomb PP panel, keeping the honeycomb PP panels stacked on both sides horizontally. This avoids the problem that the honeycomb core of the honeycomb PP panel has extremely poor lateral compressive strength. When two stacks of honeycomb PP panels are close together, the lateral contact surfaces will exert pressure on each other, and the honeycomb core cannot effectively resist this lateral compression, resulting in core layer compression deformation. This leads to the problem of the two stacks of honeycomb PP panels "tilting towards each other" (simultaneously tilting towards the middle), thus ensuring the quality of the honeycomb PP panels and contributing to the neatness and stability of the honeycomb PP panel stacking.

[0049] See Figures 12-14Specifically, the anti-collapse unit 3 includes a vertical plate 31 symmetrically arranged in the radial N direction, a drive cylinder 32 arranged on one side of the vertical plate 31, a drive plate 33 arranged at the extension end of the drive cylinder 32, a partition 34 arranged on the side of the vertical plate 31 away from the drive cylinder 32, a partition plate 35 evenly arranged between the partitions 34, a lifting member 36 arranged on the top of the partition plate 35, and a pressing member 37 evenly arranged around the bottom of the partition plate 35.

[0050] Before stacking the honeycomb PP panels, the drive cylinder 32 is started first, pushing the drive plate 33 to move upward, so that the separators 34 open at equal intervals, and drive the corresponding separators 35 to open at equal intervals simultaneously, so that the spacing between each separator 35 is equal, and the stacking of the honeycomb PP panels is layered to bear the load, so as to distribute the pressure on the bottom layer of the honeycomb PP panels.

[0051] During the operation of the anti-rollover unit 2, the lifting component 36 is also activated, providing arch support to the bottom layer of honeycomb PP panels stacked on each layer of partition 35, causing the middle part of the honeycomb PP panels to rise upwards. Simultaneously, the pressing component 37 is also activated, pressing down on the four corners of the top layer of honeycomb PP panels stacked on each layer of partition 35, preventing the four corners of the honeycomb PP panels from lifting up. This results in a higher flatness of the honeycomb PP panels stacked on each layer of partition 35. This avoids the problem that when the stacking height of the honeycomb PP panels is high, elastic or plastic bending deformation is likely to occur under continuous pressure. Such deformation would cause the middle part of the honeycomb PP panels to sink due to loss of support, while the four corners would lift up due to the relatively intact edge structure. This ensures the appearance quality of the honeycomb PP panels, which is beneficial to the subsequent use of the honeycomb PP panels.

[0052] See Figures 1-11 Furthermore, a cavity 211 is provided inside the support box 21, and through slots 212 are symmetrically provided on both side walls of the support box 21. The cavity 211 is connected to the through slots 212. The telescopic end of the telescopic cylinder 22 passes through the top of the support box 21 and extends into the cavity 211 to connect with the slider 23. A slide rail 213 is also provided inside the cavity 211, and the slider 23 can slide on the slide rail 213.

[0053] When the telescopic cylinder 22 is activated, it pushes the slider 23 to slide on the slide rail 213. During this process, the adjusting component 24 moves downward at the same time, causing the two racks 25 to move downward synchronously in the cavity 211. This drives several rotating gears 26 through the slots 212 to rotate, and causes the corresponding lifting component 27 to flip 90 degrees. During the flipping process, the lifting component 27 lifts the corresponding honeycomb PP board and inserts it under the corresponding honeycomb PP board, so that the honeycomb PP boards stacked on both sides are kept horizontally stacked, thereby ensuring the quality of the honeycomb PP board and contributing to the neatness and stability of the honeycomb PP board stacking.

[0054] See Figures 1-11 Furthermore, the lifting component 27 includes a housing 271, a miniature cylinder 272 disposed within the housing 271, a telescopic plate 273 disposed at the telescopic end of the miniature cylinder 272, a connecting rod 274 disposed at the end of the telescopic plate 273 away from the miniature cylinder 272, torsion springs 275 symmetrically sleeved on the connecting rod 274, and rubber heads 276 disposed between the torsion springs 275; one end of the housing 271 is open and the other end is closed, the closed end of the housing 271 is connected to the side wall of the corresponding rotating gear 26, the telescopic plate 273 can slide within the housing 271, and a groove 2731 is also provided at the end of the telescopic plate 273 away from the miniature cylinder 272, and both ends of the connecting rod 274 are connected to the inner wall corresponding to the groove 2731.

[0055] During the rotation of gear 26, the sleeve 271 also rotates, changing from a vertical to a horizontal position. During this process, the rubber head 276 moves against the side of the honeycomb PP panel, undergoing angular deformation due to compression, and the torsion spring 275 also undergoes torsional deformation. When the sleeve 271 becomes horizontal, the rubber head 276 is positioned between the two honeycomb PP panels. Then, the micro cylinder 272 is activated, pushing the rubber head 276 between the two honeycomb PP panels via the telescopic plate 273, causing the telescopic plate... 273. Lift the corresponding honeycomb PP board and insert it under the corresponding honeycomb PP board to keep the stacked honeycomb PP boards on both sides horizontally stacked. This avoids the problem that the honeycomb core of the honeycomb PP board has extremely poor lateral compressive strength. When two stacks of honeycomb PP boards are close together, the lateral contact surfaces will exert pressure on each other. The honeycomb core cannot effectively resist this lateral compression, which leads to core layer compression deformation. This results in the problem of the two stacks of honeycomb PP boards "tilting towards each other" (tilting towards the middle at the same time). This ensures the quality of the honeycomb PP board and is beneficial to the neatness and stability of the honeycomb PP board stack.

[0056] The soft and elastic design of the rubber head 276 reduces damage to the side core layer of the honeycomb PP board.

[0057] Example 2, while addressing the issue of poor lateral compressive strength in the honeycomb core of existing PP panels, where the lateral contact surfaces exert pressure on each other when two stacks of PP panels are pressed together, leading to core compression deformation and subsequent tilting (both tilting towards the center), still fails to resolve the problem of elastic or plastic bending deformation under continuous pressure when the stacking height of PP panels is high. This deformation causes the middle portion of the PP panels to sag due to loss of support, while the four corners warp due to the relatively intact edge structure. Therefore, the following solution is proposed: SeeFigure 12 Furthermore, a drive groove 311 is provided on one side wall of the upright plate 31, and a displacement groove 312 is provided on the other side wall. The drive groove 311 and the displacement groove 312 are connected, and the drive plate 33 can slide in the drive groove 311.

[0058] See Figure 12 Furthermore, the partition 34 includes a scissor bar mechanism 341 and displacement blocks 342 evenly arranged on one side of the scissor bar mechanism 341; the displacement blocks 342 can be connected to the corresponding hinge rods of the scissor bar mechanism 341, one of the hinge rods of the scissor bar mechanism 341 is connected to the side wall of the corresponding upright plate 31, the displacement blocks 342 can slide in the corresponding displacement groove 312, and the two ends of the partition plate 35 are connected to the hinge rods of the corresponding scissor bar mechanism 341.

[0059] Before stacking the honeycomb PP panels, the drive cylinder 32 is started first, pushing the drive plate 33 to move upward in the drive groove 311, so that the scissor bar mechanism 341 opens at equal intervals, thereby causing the corresponding displacement block 342 to slide in the displacement groove 312, and driving the corresponding partition plate 35 to open at equal intervals simultaneously, so that the spacing between each partition plate 35 is equal, and the stacking of honeycomb PP panels is layered to bear the load, so as to distribute the pressure of the bottom layer of honeycomb PP panels.

[0060] It should be noted that the scissor lever mechanism 341 consists of two shearing rods, which are hinged together by a hinge rod. This is existing technology and will not be described in detail here.

[0061] See Figure 13 Furthermore, the lifting member 36 includes a spring sheet 361, a compression cylinder 362 symmetrically arranged at both ends of the spring sheet 361, and a miniature telescopic column 363 arranged below the spring sheet 361; the top of the partition plate 35 is provided with a placement groove 351, the spring sheet 361 is located in the placement groove 351, and the spring sheet 361 is horizontally aligned with the top of the partition plate 35.

[0062] In this process, two compression cylinders 362 are activated simultaneously to compress both ends of the spring sheet 361, causing it to deform and arch upwards. During this process, the micro telescopic column 363 is also activated, extending its telescopic end to apply an upward force to the spring sheet 361, allowing it to arch upwards and provide arched support for the bottom layer of honeycomb PP panels stacked on each layer of partition plate 35. This lifts the middle part of the honeycomb PP panels upwards, preventing elastic or plastic bending deformation that can easily occur under continuous pressure when the stacking height of the honeycomb PP panels is high. Such deformation would cause the middle part of the honeycomb PP panels to sink due to loss of support, thus ensuring the appearance quality of the honeycomb PP panels and facilitating their subsequent use.

[0063] See Figure 14 Furthermore, the pressing component 37 includes a first support 371, a first gear 372 rotatably connected to the first support 371, a second support 373 disposed on one side of the first gear 372, a second gear 374 rotatably connected to the second support 373, a chain 375 sleeved on the first gear 372 and the second gear 374, a rotating plate 376 symmetrically rotatably connected to both sides of the first support 371, an adjusting cylinder 377 disposed on the side of the rotating plate 376 away from the first support 371, and a chain 375 rotatably connected to the adjusting cylinder 376. The spring 378 at the telescopic end of the 77 and the pressing plate 379 disposed at the end of the second support 373 away from the second support 373; the end of the first support 371 away from the first gear 372 is connected to the bottom of the partition plate 35, the side wall of the rotating plate 376 away from the first support 371 is rotatably connected to the corresponding side wall of the second support 373, the end of the adjusting cylinder 377 away from the spring 378 is rotatably connected to the bottom of the partition plate 35, and the end of the spring 378 away from the adjusting cylinder 377 is connected to the side wall of the corresponding rotating plate 376.

[0064] When the four corners of the honeycomb PP panels stacked on each layer of partition 35 are raised, the drive cylinder 32 is activated again, and the drive plate 33 pulls the partition 34 to retract at equal intervals. At this time, the pressing plate 379 will press the corresponding four corners of the honeycomb PP panels simultaneously. Since the pressing piece 37 is placed vertically, the rotating plate 376 is vertically distributed, and the spring 378 is in a normal tension state. During this process, the adjusting cylinder 377 will also be activated, continuously extending and retracting. By pulling the spring 378, it drives the rotating plate 376 to rotate, thereby causing the pressing plate 379 to also move. And because the rotating plate During rotation, 376 will also drive the second gear 374 to rotate. The chain 375 limits the movement between the second gear 374 and the first gear 372. Therefore, the second gear 374 will rotate and mesh within the chain 375, so that the pressing plate 379 always remains horizontal when pressing. This avoids the problem of elastic or plastic bending deformation that easily occurs under continuous pressure when the stacking height of the honeycomb PP board is high. Such deformation will cause the four corners of the honeycomb PP board to curl up due to the relatively intact edge structure, thus ensuring the appearance quality of the honeycomb PP board and thus benefiting the subsequent use of the honeycomb PP board.

[0065] See Figures 8-9Furthermore, the adjusting component 24 includes a double-rod double-acting cylinder 241 and plug-in blocks 242 symmetrically arranged at both ends of the double-rod double-acting cylinder 241; one side of the double-rod double-acting cylinder 241 is connected to the side wall of the slider 23; a plug-in groove 251 is also provided on the side wall of the rack 25 away from the rotating gear 26, and the plug-in block 242 can be inserted into the corresponding plug-in groove 251. The rack 25 is located in the cavity 211, and the rotating gear 26 is located in the through groove 212. The two ends of the rotating gear 26 are rotatably connected to the inner wall of the through groove 212, and the rotating gear 26 can mesh with the rack 25 for transmission.

[0066] When it is necessary for the two racks 25 to rise and fall synchronously, the double-rod double-acting cylinder 241 can be activated, so that the plug blocks 242 at both ends of the double-rod double-acting cylinder 241 extend simultaneously and plug into the corresponding plug slots 251; when it is necessary to connect a rack 25 alone, the double-rod double-acting cylinder 241 only needs to extend the corresponding plug block 242.

[0067] It should be noted that the double-rod double-acting cylinder 241 controls the movement on both sides through two independent air inlets.

[0068] In the existing technology, some manufacturers package each honeycomb PP panel individually with aluminum foil insulation bags before stacking. However, uneven expansion of the aluminum foil insulation bags can cause uneven support surfaces of the upper honeycomb PP panels. Pressure may be concentrated on a few contact points of the bottom honeycomb PP panels in some areas, which may cause the honeycomb core of the bottom honeycomb PP panels to be crushed at high pressure points, forming permanent depressions. At the same time, the stack may tilt to the other side (outside), further increasing the lateral shear force on the bottom honeycomb PP panels.

[0069] Therefore, by placing the anti-tipping unit 2 on the outside of the stacked honeycomb PP panels and then activating one side of the anti-tipping unit 2 through the adjusting component 24, the problem of the stack possibly tilting to the other side (outside) can be avoided, thereby ensuring the stability of the honeycomb PP panel stacking.

[0070] As for the problem that the honeycomb core of the bottom honeycomb PP board may be crushed at high pressure points, forming permanent dents, the separator 34 can be used to load the stacked honeycomb PP boards in layers to reduce the damage to the bottom honeycomb PP board caused by the superimposed gravity; the lifting member 36 at the same time provides limiting support for the central area with more contact points, restricting its free expansion.

[0071] Example 3: A continuous handling and palletizing method for PP sheet production, using the continuous handling and palletizing device for PP sheet production as described above, includes the following steps: S1. Before stacking the honeycomb PP panels, the drive cylinder 32 is started first, pushing the drive plate 33 to move upward, so that the separators 34 open at equal intervals, and drive the corresponding separators 35 to open at equal intervals at the same time, so that the spacing between each separator 35 is equal, and the stacking of the honeycomb PP panels is layered to bear the load, so as to distribute the pressure of the bottom layer of the honeycomb PP panels.

[0072] S2. When stacking honeycomb PP panels, one side of the honeycomb PP panels is transported and stacked by a set of transport units 1, and the other side of the honeycomb PP panels is transported and stacked by another set of transport units 1. This allows the honeycomb PP panels on one side to be stacked on one side of the anti-tipping unit 2 and on the corresponding partition plate 35, while the honeycomb PP panels on the other side of the anti-tipping unit 2 are stacked on the other corresponding partition plate 35. Thus, the anti-tipping unit 2 provides spaced support for the honeycomb PP panels on both sides.

[0073] S3. After the honeycomb PP panels on both sides are stacked simultaneously, the telescopic cylinder 22 is activated. Its telescopic end pushes the slider 23 and the adjusting member 24 to move downwards simultaneously, so that the two racks 25 move downwards synchronously, thereby driving several rotating gears 26 to rotate and flip the corresponding lifting member 27 by 90 degrees. During the flipping process, the lifting member 27 lifts the corresponding honeycomb PP panel and inserts it into the bottom of the corresponding honeycomb PP panel.

[0074] S4. During the operation of S3, the lifting component 36 will also be activated to provide arch support for the bottom layer of honeycomb PP panels stacked on each layer of partition 35, so that the middle part of the honeycomb PP panels is lifted upwards; at the same time, the pressing component 37 will also be activated to press down the four corners of the top layer of honeycomb PP panels stacked on each layer of partition 35, so that the four corners of the honeycomb PP panels no longer lift up, thereby making the honeycomb PP panels stacked on each layer of partition 35 have a high degree of flatness.

[0075] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
