Description

Technical Field

[0001] This invention relates to the field of gypsum board facing paper transportation technology, and in particular to a protective device for transporting gypsum board facing paper rolls. Background Technology

[0002] The finished gypsum board facing paper rolls are stored and transported lying flat, with the axis of the paper roll pointing in the direction of travel of the transport vehicle (container, car), similar to the transport of steel coils. The reason why the paper rolls cannot be placed with the axis perpendicular to the surface is that the two ends of the paper rolls must not be damaged, otherwise the gypsum board cannot be produced.

[0003] Currently, transporting paper rolls in a flat, horizontal manner still presents the problem of damaging the rolls. Traditional transport protection involves fixing right-angled triangular blocks to both sides of the roll, with the pointed ends of the blocks against the bottom of the roll and the beveled surfaces supporting the roll's curved surface. However, the inventors found in practical use that while the blocks can impede the roll's rolling during transport and prevent large-scale damage, they easily cause significant damage to the roll's surface. Since the roll's circumference increases towards the surface, this can result in tens of meters of the cover paper being scrapped, causing annual losses of up to millions of yuan for companies due to transport damage. Summary of the Invention

[0004] The purpose of this invention is to provide a protective device for transporting gypsum board facing paper rolls, which can effectively protect the paper rolls during transportation and minimize damage to the surface of the paper rolls. At the same time, it can be quickly installed on both sides of the paper rolls for protection after the paper rolls are placed in place.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] The present invention provides a protective device for transporting gypsum board facing paper rolls, which is disposed on both sides of the paper roll to prevent the paper roll from rolling in the transport vehicle. It includes a thrust stop, a flexible support belt, and a tensioning mechanism, wherein:

[0007] The thrust stop includes an anti-slip seat with a rough bottom surface that contacts the transport vehicle. The anti-slip seat has a rectangular groove, and multiple sets of parallel rotating rollers are arranged in the rectangular groove. The outer circumference of each roller is covered with an elastic anti-slip pad. When the roller is not under pressure, the rough bottom surface of the anti-slip seat is higher than the lower edge of the roller. As the pressure on the roller increases, the anti-slip pad is gradually compressed so that the lower edge of the roller can remain flush with the rough bottom surface of the anti-slip seat.

[0008] The tensioning mechanism includes an active roller, a tensioning roller, a fixed roller, and a load-bearing assembly. The two ends of the flexible support belt are respectively fixed to the active roller and the fixed roller. The tensioning roller is disposed between the active roller and the fixed roller and is used to tension the flexible support belt. The load-bearing assembly includes a support arm for supporting the active roller and the tensioning roller and a drive rack fixed to both sides of the support arm. The support arm is slidably mounted on the anti-slip seat through a horizontally arranged groove, and the roller is provided with rolling gears at both ends that cooperate with the drive rack, so that when the support arm slides horizontally along the anti-slip seat, the drive rack can rotate the roller through the rolling gears.

[0009] Preferably, the flexible support belt is a belt woven from para-aramid fibers.

[0010] Preferably, both the driving roller and the fixed roller include a fastening assembly for fixing the flexible support belt. The fastening assembly includes a clamping ring and a locking bolt for fixing the clamping ring. The clamping ring presses the end of the flexible support belt against the outer side of the driving roller or the fixed roller, and the inner side of the clamping ring is evenly provided with clamping teeth. The clamping ring also has an outlet for leading out the flexible support belt. The clamping ring has a hinged end located on the outer side of the driving roller or the fixed roller, and a locking end fixed to the driving roller or the fixed roller by the locking bolt.

[0011] Preferably, it further includes a lever assembly for driving the rotation of the drive roller, the drive roller being fixedly mounted on the drive shaft, the lever assembly including a ratchet fixedly mounted on the drive shaft and a pawl disposed on the side of the support arm, and the drive shaft also having a wrench mounted on it via a one-way bearing.

[0012] Preferably, the support arm includes a vertically arranged support box and a support platform that slides vertically with the support box. The tension roller is arranged at the top of the support platform through a tension shaft, and a cantilever frame for assembling the drive roller is provided on the side of the support platform away from the fixed roller.

[0013] Preferably, the pawl is mounted on a fixed block located on the side of the cantilever frame, and the fixed block has a movable rod provided by a threaded structure. The pawl is controlled by the movable rod to extend into or out of the tooth gap of the ratchet.

[0014] Preferably, an elastic rubber pad is provided between the bottom end of the support platform and the bottom surface of the support box that houses it.

[0015] Preferably, the anti-slip pad has evenly spaced arc-shaped recesses along the outer circumference of the roller.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] First, the paper roll transport protection device of the present invention has the advantages of convenient installation and proper installation. After the paper roll is placed in place by a forklift, it is only necessary to place one on each side of the paper roll close to the curved surface of the paper roll, and then continuously press the wrench to move the thrust seat toward the paper roll a certain distance to press against the paper roll and maintain sufficient clamping force. In contrast, the prior art can easily loosen the pad by manually placing the pad.

[0018] Secondly, the paper roll transport protection device of the present invention has the advantage of good support effect. After being placed in place, the flexible support belt of the present invention adaptively forms an arc shape that adheres to the paper roll of the specified size, thereby maintaining a large support area with the paper roll to provide better support effect. In contrast, the pads in the prior art cannot adapt well to paper rolls of various sizes. More importantly, during transportation, the flexible support belt of the present invention can adaptively cope with the shaking and bumping of the paper roll, thereby providing dynamic protection for the transport of the paper roll.

[0019] Furthermore, in existing technologies, wooden boards are typically laid underneath the paper roll during transport to serve as a transport platform, acting as a shock absorber and buffer. The pads are also made of wood (covered with rubber), and can be locked to the wooden boards with nails to ensure stability. However, this method suffers from drawbacks such as cumbersome removal of the pads and inconvenience in reusing them. In contrast, the paper roll transport protection device of this invention is easy to disassemble and can be reused. After transporting the paper roll to its destination, the device can be quickly removed simply by unlocking the pawl with the movable lever. Attached Figure Description

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 7 The diagram illustrates a protective device for transporting gypsum board facing paper rolls. The device is positioned on both sides of the paper roll 100 to prevent it from rolling within transport vehicles such as containers or carriages. It includes a thrust bearing 200, a flexible support belt 300, and a tensioning mechanism 400.

[0039] The thrust seat 200 includes an anti-slip seat 210 with a rough bottom surface 211 that contacts the transport vehicle. A rectangular groove 220 is provided in the anti-slip seat 210, and multiple sets of parallel rotating rollers 230 are arranged in the rectangular groove 220. The outer circumference of each roller 230 is covered with an elastic anti-slip pad 231. When the roller 230 is not under pressure, the rough bottom surface 211 of the anti-slip seat 210 is higher than the lower edge of the roller 230. As the pressure on the roller 230 increases, the anti-slip pad 231 is gradually compressed so that the lower edge of the roller 230 can remain flush with the rough bottom surface 211 of the anti-slip seat 210.

[0040] The tensioning mechanism 400 includes an active roller 410, a tensioning roller 420, a fixed roller 430, and a load-bearing assembly 440. The two ends of the flexible support belt 300 are respectively fixed to the active roller 410 and the fixed roller 430. The tensioning roller 420 is disposed between the active roller 410 and the fixed roller 430 and is used to tension the flexible support belt 300. The load-bearing assembly 440 includes a support arm 450 for supporting the active roller 410 and the tensioning roller 420 and a drive rack 457 fixed to both sides of the support arm 450. The support arm 450 is slidably mounted on the anti-slip seat 210 through a horizontally arranged slide groove 458. The roller 230 is provided with rolling gears 233 at both ends that cooperate with the drive rack 457, so that when the support arm 450 slides horizontally along the anti-slip seat 210, the drive rack 457 can rotate the roller 230 through the rolling gears 233.

[0041] Combination Figure 4 As shown, during the process of approaching and carrying the paper roll 100, the rotation of the drive roller 410 will tighten the flexible support belt 300 and cause the flexible support belt 300 to be wound on the drive roller 410. As the length of the flexible support belt 300 shortens, the bottom of the support arm 450 will slide towards the fixed roller 430, thereby driving the rack 457 to drive the rolling gear 233 to rotate and causing the thrust seat 200 to gradually approach directly below the paper roll 100.

[0042] As the flexible support belt 300 is squeezed by the outer surface of the paper roll 100 and becomes an arc shape attached to it, the pressure of the flexible support belt 300 on the paper roll 100 causes the entire device to be subjected to a downward pressure. As the drive roller 410 rotates, the squeezing pressure gradually increases, and the pressure on the device gradually increases, eventually causing the anti-slip pad 231 covered by the roller 230 to be gradually compressed, so that the lower edge of the roller 230 can remain flush with the rough bottom surface 211 of the anti-slip seat 210. Through the cooperation between the anti-slip pad 231 and the rough bottom surface 211, the thrust seat 200 generates sufficient friction with the transport vehicle when subjected to the squeezing pressure of the paper roll 100 to prevent the paper roll 100 from rolling as a whole.

[0043] It is worth mentioning that in the prior art, the transportation of paper rolls 100 typically uses containers, truck beds, etc., as transportation tools, and a flat wooden board is laid on the surface of the transportation tool to facilitate the support of the paper rolls 100. However, in this invention, it is not necessary to fix the pads to the flat wooden board with nails to ensure the stability of the paper rolls 100 during transportation. Therefore, in the transportation process, the flat wooden board can be replaced with other materials, and in particular, a flat plate or coated material with a high coefficient of friction can be provided only at the location supporting the paper rolls 100 and where the device is placed, so as to facilitate reuse and achieve the purpose of energy saving, environmental protection, and cost reduction in transportation.

[0044] Secondly, in this invention, the flexible support belt 300 should be made of a belt woven from a flexible fiber material with high modulus and high strength to cope with the extrusion pressure on the paper roll 100 during transportation, such as para-aramid fiber commonly used in engineering materials.

[0045] Furthermore, the flexible support strip 300 should be replaced promptly after multiple transports to prevent losses caused by the material of the flexible support strip 300 breaking down after repeated transports. Therefore, in some embodiments, such as Figure 6 As shown, both the active roller 410 and the fixed roller 430 include a fastening assembly 460 for fixing the flexible support belt 300, so as to facilitate the timely and convenient periodic replacement of the flexible support belt 300. The fastening assembly 460 includes a clamping ring 461 and a locking bolt 462 for fixing the clamping ring 461. The clamping ring 461 presses the end of the flexible support belt 300 against the outer side of the active roller 410 or the fixed roller 430, and the inner side of the clamping ring 461 is evenly provided with clamping teeth 463. The clamping ring 461 is also provided with an outlet 464 for leading out the flexible support belt 300. The clamping ring 461 has a hinged end on the outer side of the active roller 410 or the fixed roller 430, and a locking end fixed to the active roller 410 or the fixed roller 430 by the locking bolt 462. The fastening assembly 460 allows for easy disassembly and installation of the flexible support belt 300, and ensures the stability of the ends of the flexible support belt 300 during use.

[0046] Combination Figure 3 As shown, in order to facilitate the rotation of the drive roller 410 and ensure that the device is quickly installed before the paper roll 100 is transported, the device also includes a lever assembly 500 for driving the drive roller 410 to rotate. The drive roller 410 is fixedly mounted on the drive shaft 411. The lever assembly 500 includes a ratchet 510 fixedly mounted on the drive shaft 411 and a pawl 520 provided on the side of the support arm 450. The drive shaft 411 is also equipped with a wrench 540 through a one-way bearing 530. Thus, by continuously turning the wrench 540 counterclockwise, the construction worker can control the drive shaft 411 to rotate counterclockwise synchronously via the one-way bearing 530. This causes the drive roller 410 to wind up the flexible support belt 300. After the ratchet 510 rotates synchronously with the drive shaft 411, the pawl 520 locks the position of the ratchet 510 to position the drive shaft 411. Then, the construction worker turns the wrench 540 clockwise to reset it. Due to the action of the one-way bearing 530, the wrench 540 and the drive shaft 411 are in a relative rotational state during the reset process, thus the wrench 540 is successfully reset, and the next turning process can then begin.

[0047] Combination Figure 5As shown, in some embodiments, the support arm 450 includes a vertically arranged support box 451 and a support platform 452 that slides vertically with the support box 451. The tension roller 420 is mounted on the top of the support platform 452 via a tensioning shaft, and a cantilever frame 453 for assembling the drive roller 410 is provided on the side of the support platform 452 away from the fixed roller 430. An elastic rubber pad 454 is provided between the bottom end of the support platform 452 and the inner bottom surface of the support box 421 in which it is housed. Figure 5 As shown, during the installation process, when the support arm 450 moves toward the paper roll 100, as the flexible support belt 300 gradually presses against the surface of the paper roll 100, the tension roller 420 also gradually approaches the paper roll 100 until it touches the paper roll 100. At this time, the flexible support belt 300 at the fixed roller 430 may not be fully in place yet. In order to further ensure that the flexible support belt 300 is installed in place, the height of the support arm 450 can be reduced to a certain extent in the vertical direction, that is, the elastic pad 454 is compressed. Thus, when the height of the support arm 450 is reduced, the flexible support belt 300 can be further wound up so that the fixed roller 430 is closer to the paper roll 100, which means that the flexible support belt 300 at the fixed roller 430 has a better adhesion to the paper roll 100.

[0048] After transportation is completed, this device needs to be disengaged promptly and conveniently so that the paper roll 100 can be removed by a forklift, such as... Figure 3 As shown, the pawl 520 is therefore mounted on a fixed block 455 located on the side of the cantilever 453, and the fixed block 455 has a movable rod 456 provided by a threaded structure. The pawl 520 is controlled to extend into or retract from the tooth gap of the ratchet 510 by the movable rod 456. Thus, the pawl 520 can be disengaged from the ratchet 510 simply by turning the end of the movable rod 456, thereby disengaging the device. In addition, in some embodiments, the stability of the threaded structure between the movable rod 456 and the fixed block 455 can be further ensured by conventional manual means such as using shims.

[0049] like Figure 7 As shown, in some embodiments, the anti-slip pad 231 has evenly distributed arc-shaped recesses 232 along the outer circumferential surface of the roller 230. These evenly distributed arc-shaped recesses 232 on the anti-slip pad 231 allow air to escape when the anti-slip pad 231 is compressed and deformed, forming a uniform micro-suction cup structure that adheres to the flat plate supporting the device, thereby increasing the pressure-bearing capacity of the thrust seat 200.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
