Description

Technical Field

[0001] This utility model relates to the field of decorative paper packaging technology, specifically to a packaging device for decorative paper. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In the product structure, decorative paper mainly serves to provide decorative patterns and cover to prevent the glue from seeping out of the underlying layer. Decorative paper needs to be packaged before transportation for convenient use.

[0003] If the outer surface of the decorative paper is not pressed tightly during the packaging process, gaps may appear between the subsequently rolled-up decorative papers, thus affecting the packaging effect. Therefore, this utility model designs a packaging device for decorative paper to solve the above problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a packaging device for decorative paper, including a base, a slot on the upper surface of the base, a packaging mechanism rotatably connected to the inner surface of the base, and a detection mechanism installed inside the slot; the slot facilitates the installation of the detection mechanism, and the packaging mechanism can package the decorative paper.

[0005] The packaging mechanism includes a motor, the output shaft of which is fitted with a rotating disk. A threaded rod is mounted at the center of the inner surface of the rotating disk. A threaded ring is threaded onto the outer surface of the threaded rod. A packaging tube is fitted and slidably connected to the outer surface of the threaded rod. A patch is fixedly connected to the outer surface of the packaging tube. Decorative paper is wrapped around the outer surface of the packaging tube, and the first end of the decorative paper is secured with the patch. The threaded ring spirals down along the outer surface of the threaded rod and finally secures the upper end of the packaging tube.

[0006] Furthermore, the outer surface of the motor is fixedly connected to the inner surface of the base, the bottom of the rotating disk is rotatably connected to the upper surface of the base, and the threaded ring is positioned above the packing cylinder.

[0007] Furthermore, the detection mechanism includes a slide rail, a slide table slidably connected to the outer surface of the slide rail, a connecting plate fixedly connected to the upper surface of the slide table, a distance sensor mounted on the side of the connecting plate near the packing cylinder, disassembly components mounted on both sides of the connecting plate, a pressing component mounted on the inner surface of the disassembly component, an adhesive plate provided on one side of the pressing component, a telescopic rod fixedly connected to the side of the adhesive plate away from the packing cylinder, and an inclined plate fixedly connected to the end of the telescopic rod away from the adhesive plate. The slide rail can control the linear movement of the slide table and the connecting plate, and the distance sensor can measure the distance between the packing cylinder and the adhesive plate. As more and more decorative paper is wrapped around, the distance to the distance sensor decreases, and the distance sensor has high accuracy. The side of the adhesive plate near the packing cylinder is designed with an arc shape to facilitate subsequent adhesion to the outer surface of the packing cylinder.

[0008] Furthermore, both ends of the slide rail are fixedly connected to the inner surface of the slot, and the bottom of the inclined plate is fixedly connected to the side of the connecting plate away from the packing cylinder.

[0009] Furthermore, the pressing component includes a pressing rod, with a bent rod rotatably connected to its inner surface. A first semicircular tube is mounted on the outer surface of the bent rod, and a second semicircular plate is mounted on the inner wall of the first semicircular tube. A spring band is provided in the internal space enclosed by the first and second semicircular plates. A pressure sensor is fixedly connected to the end of the spring band away from the pressing rod, and a wire is electrically connected to the side of the pressure sensor away from the spring band. A power source is fixedly connected to the end of the wire away from the pressure sensor. The pressing rod can rotate around the outer surface of the bent rod, and appropriately presses the decorative paper during the winding process. The first and second semicircular tubes are fixedly connected to each other through a fixing pin and a fixing hole. The spring band has the same function as a spring, both having elasticity and reset functions. The pressure sensor can measure the pressure brought by the spring band. The wire and the power source are both installed on the inner surface of the first semicircular tube. When the power source needs to be replaced, the first and second semicircular tubes can be disassembled.

[0010] Furthermore, the end of the spring band away from the pressure sensor is fixedly connected to the end of the bent bar near the pressure sensor, and the pressure sensor is installed inside the first semi-circular tube.

[0011] Furthermore, the disassembly component includes a fixing rod, the outer surface of which is rotatably connected to an opening and closing circular plate. A first magnetic block is fixedly connected to the inner wall of the opening and closing circular plate, and a second magnetic block is attracted to the side of the first magnetic block closest to the connecting plate. The opening and closing circular plate, in conjunction with the connecting plate, fixes the first and second semi-circular tubes. The opening and closing circular plate also allows for merging or separation through the first and second magnetic blocks. When merged, it fixes the first and second semi-circular tubes; when separated, it facilitates the disassembly of the first and second semi-circular tubes.

[0012] Furthermore, both the upper and lower ends of the fixing rod are fixedly connected to the inner surface of the connecting plate, the inner surface of the opening and closing circular plate is fixedly connected to the outer surface of the first semi-circular tube, and the second magnetic block is installed on the inner surface of the connecting plate near the first magnetic block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves wrapping decorative paper around the outer surface of a packing tube and packing the decorative paper by rotating the packing tube. During the packing process, a pressing rod is used to adhere the decorative paper to the outer surface, which can prevent gaps from forming between the paper pieces during rotation and further avoid the problem of gaps affecting the packing effect due to the wrapping of decorative paper.

[0015] 2. In this invention, when the decorative paper first contacts the clamping rod, the elastic deformation of the bent rod and spring belt absorbs the squeezing force, preventing the decorative paper from detaching from the adhesive due to the initial instantaneous contact. At the same time, as the decorative paper continues to wrap around the outer surface of the packing tube, the paper thickness is detected by a distance sensor, and the distance between the clamping rod and the paper is adjusted by a slide table to ensure that the pressure of the clamping rod is always adapted to the current state of the paper. This avoids scratches or indentations on the paper surface due to excessive pressure, and also avoids loose wrapping of the paper due to insufficient pressure.

[0016] 3. This utility model uses a pressure sensor and a clamping rod to determine when the decorative paper is finished winding by the instantaneous decrease in pressure. It can then control the adhesive plate to apply adhesive to the outer surface of the decorative paper, avoiding paper springback or interlayer loosening caused by the loss of pressure at the end of the decorative paper after the clamping rod resets. At the same time, if any one of the pressure sensors on both sides of the connecting plate detects that the winding is complete, it can automatically apply adhesive, avoiding the problem of missed adhesive application due to the failure of a single sensor.

[0017] 4. This utility model utilizes the strong magnetic attraction between the first and second magnetic blocks to fix the two semi-circular tubes. The magnetic separation of the components can be overcome simply by manually rotating the opening and closing circular plate. No tools are required, and the power supply replacement time can be shortened. This avoids the problem that the pressure sensor cannot measure the extrusion pressure of the subsequent decorative paper when there is no power supply. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a packaging device for decorative paper, including a base 1, a slot 2 is provided on the upper surface of the base 1, a packaging mechanism 3 is rotatably connected to the inner surface of the base 1, and a detection mechanism 4 is installed inside the slot 2; the slot 2 is designed to facilitate the installation of the detection mechanism 4, and the packaging mechanism 3 can package the decorative paper.

[0028] First, the decorative paper is wrapped and packaged by the packaging mechanism 3. During the packaging process, the distance between the decorative paper and the detection mechanism 4 is measured by the detection mechanism 4 to facilitate proper pressing of the outer surface of the decorative paper.

[0029] The packaging mechanism 3 includes a motor 31, with a rotating disk 32 mounted on the output shaft of the motor 31. A threaded rod 33 is mounted at the center of the inner surface of the rotating disk 32. A threaded ring 34 is threadedly connected to the outer surface of the threaded rod 33. A packaging tube 35 is fitted and slidably connected to the outer surface of the threaded rod 33. A patch 36 is fixedly connected to the outer surface of the packaging tube 35. Decorative paper is wrapped around the outer surface of the packaging tube 35, and the first end of the decorative paper is secured by the patch 36. The threaded ring 34 spirals down along the outer surface of the threaded rod 33 and finally secures the upper end of the packaging tube 35. The packaging tube 35 can be made of paper material, which is environmentally friendly and cost-effective.

[0030] The outer surface of the motor 31 is fixedly connected to the inner surface of the base 1, the bottom of the rotating disk 32 is rotatably connected to the upper surface of the base 1, and the threaded ring 34 is positioned above the packing cylinder 35.

[0031] Insert the packing tube 35 vertically into the outer surface of the threaded rod 33 until the bottom of the packing tube 35 enters the inner surface of the rotating disk 32. Then, place the threaded ring 34 on the outer surface of the threaded rod 33 and rotate it until the threaded ring 34 rotates to the upper surface of the packing tube 35 and fixes it appropriately. Then, attach the first end of the decorative paper to the outer surface of the adhesive tape 36. The adhesive tape 36 fixes the end of the decorative paper. After the end is fixed, the motor 31 starts and drives the packing tube 35 to rotate. The adhesive tape 36 on the packing tube 35 can drive the decorative paper to rotate and wrap. The other side of the decorative paper is held manually by the staff to align the angle and keep it in the same horizontal direction to avoid the decorative paper being tilted during wrapping.

[0032] The detection mechanism 4 includes a slide rail 41, a slide table 42 slidably connected to the outer surface of the slide rail 41, a connecting plate 43 fixedly connected to the upper surface of the slide table 42, a distance sensor 44 installed on the side of the connecting plate 43 near the packing cylinder 35, disassembly components 45 installed on both sides of the connecting plate 43, a pressing component 46 installed on the inner surface of the disassembly component 45, an adhesive plate 47 provided on one side of the pressing component 46, a telescopic rod 48 fixedly connected to the side of the adhesive plate 47 away from the packing cylinder 35, and an inclined plate 49 fixedly connected to the end of the telescopic rod 48 away from the adhesive plate 47. The slide rail 41 can control the linear movement of the slide table 42 and the connecting plate 43, and the distance sensor 44 can measure the distance between the packing cylinder 35 and the adhesive plate 47. As more and more decorative paper is wrapped, the distance to the distance sensor 44 becomes closer and closer, and the distance sensor 44 has high accuracy. The side of the adhesive plate 47 near the packing cylinder 35 is set with an arc-shaped surface, which facilitates subsequent bonding to the outer surface of the packing cylinder 35.

[0033] Both ends of the slide rail 41 are fixedly connected to the inner surface of the slot 2, and the bottom of the inclined plate 49 is fixedly connected to the side of the connecting plate 43 away from the packing cylinder 35.

[0034] The clamping component 46 includes a clamping rod 461, a bent rod 462 rotatably connected to the inner surface of the clamping rod 461, a first semi-circular tube 463 installed on the outer surface of the bent rod 462, a second semi-circular plate 464 installed on the inner wall of the first semi-circular tube 463, a spring band 465 provided in the internal space enclosed by the first semi-circular plate and the second semi-circular plate 464, a pressure sensor 466 fixedly connected to the end of the spring band 465 away from the clamping rod 461, a wire 467 electrically connected to the side of the pressure sensor 466 away from the spring band 465, and a power supply 468 fixedly connected to the end of the wire 467 away from the pressure sensor 466. The clamping rod 461 can rotate around the outer surface of the bent rod 462 and appropriately clamp the decorative paper during the winding process. The first semicircular tube 463 and the second semicircular tube 464 are fixedly connected to each other through a fixing pin and a fixing hole. The spring band 465 has the same function as the spring, both having elasticity and reset functions. The pressure sensor 466 can measure the pressure brought by the spring band 465. The wire 467 and the power supply 468 are both installed on the inner surface of the first semicircular tube 463. When the power supply 468 needs to be replaced, the first semicircular tube 463 and the second semicircular tube 464 can be disassembled.

[0035] The end of the spring band 465 away from the pressure sensor 466 is fixedly connected to the end of the bent bar 462 near the pressure sensor 466. The pressure sensor 466 is installed inside the first semi-circular tube 463.

[0036] When in use, when there is no decorative paper on the outer surface of the packing tube 35, the distance between the packing tube 35 and the distance sensor 44 can be measured by the distance sensor 44. When the decorative paper is wrapped around the outer surface of the packing tube 35, when the decorative paper rotates to the opposite side of the distance sensor 44, the distance sensor 44 can detect the distance between the decorative paper and the distance sensor 44, and thus determine the thickness of the decorative paper. The decorative paper has a certain thickness, which can be detected by the precision distance sensor 44.

[0037] Therefore, during the winding of the decorative paper, when the first end of the decorative paper first touches the pressing rod 461, the distance sensor 44 cannot detect the thickness of the decorative paper. The decorative paper will exert an appropriate force on the pressing rod 461, and the squeezing force is relieved by the cooperation of the bent rod 462 and the spring belt 465. When the first end of the decorative paper rotates to the opposite side of the distance sensor 44, after the distance sensor 44 detects the thickness of the decorative paper, it can control the squeezing force of the pressing rod 461 on the decorative paper. That is, it controls the slide table 42 to move linearly along the outer surface of the slide rail 41, controls the appropriate distance between the pressing rod 461 and the decorative paper, so that the pressing rod 461 can squeeze the decorative paper appropriately, avoiding gaps between the decorative paper due to insufficient pressure, and avoiding friction damage between the paper and the pressing rod 461 due to excessive pressure. During the rotation of the decorative paper, it can drive the rotation of the pressing rod 461 to a certain extent.

[0038] As the decorative paper continues to wrap, the distance between the wrapped decorative paper and the distance sensor 44 decreases. The distance sensor 44 can then synchronously adjust the distance between the pressure bar 461 and the decorative paper to appropriately control the pressure exerted by the pressure bar 461 on the decorative paper, ensuring that the pressure bar 461 always maintains a suitable pressure. During the continuous wrapping process, the decorative paper also exerts appropriate pressure on the pressure bar 461, the curved bar 462, and the spring band 465. This pressure is transmitted to the pressure sensor 466, which judges the pressure in real time. Since the pressure only increases as the decorative paper wraps, the distance sensor 44 measures the distance to bring it back to an appropriate level. However, overall, the pressure sensed by the pressure sensor 466 is an intermittent increase. Only when the decorative paper is fully wrapped and the pressure bar 461 is no longer pressed against the outer surface of the decorative paper, will the pressure decrease again due to the rotation of the decorative paper, reducing it to a thinner layer. When the pressure sensed by the pressure sensor 466 suddenly decreases, the clamping rod 461 and the bending rod 462 will move towards the side closer to the packing cylinder 35 under the elasticity of the spring belt 465. This indicates that the decorative paper is wrapped. As long as either pressure sensor 466 on both sides of the connecting plate 43 senses this situation, it indicates that the decorative paper is wrapped and packed. At this time, the telescopic rod 48 is controlled to extend the adhesive plate 47. The adhesive plate 47 is used to apply adhesive to the outer surface of the decorative paper to prevent the end of the wrapped decorative paper from expanding outward under the pressure of the clamping rod 461 on one side. This further prevents the wrapped decorative paper from loosening from the inside out.

[0039] After the decorative paper is wrapped and glued, the slide table 42 moves the pressing component 46 and the glue-applying plate 47 away from the decorative paper. This prevents the decorative paper from being worn as it is pulled upwards from the packing cylinder 35 due to the tightness of the pressing rod 461. At this point, the outer surface of the decorative paper is wrapped and tightly fixed by the adhesive tape. The threaded ring 34 is rotated to remove it from the top of the packing cylinder 35. Then, the packing cylinder 35 and the decorative paper on it can be removed, thus completing the wrapping and removal of the decorative paper.

[0040] Example 2:

[0041] Please see Figure 1 - Figure 6 This utility model provides a technical solution: Based on Embodiment 1, the disassembly component 45 includes a fixing rod 451, an opening and closing circular plate 452 rotatably connected to the outer surface of the fixing rod 451, a first magnetic block 453 fixedly connected to the inner wall of the opening and closing circular plate 452, and a second magnetic block 454 adsorbed on the side of the first magnetic block 453 near the connecting plate 43. The opening and closing circular plate 452, in conjunction with the connecting plate 43, fixes the first semi-circular tube 463 and the second semi-circular tube 464. The opening and closing circular plate 452 also achieves merging or separation through the first magnetic block 453 and the second magnetic block 454. When merged, it fixes the first semi-circular tube 463 and the second semi-circular tube 464; when separated, it facilitates the disassembly of the first semi-circular tube 463 and the second semi-circular tube 464.

[0042] The upper and lower ends of the fixing rod 451 are fixedly connected to the inner surface of the connecting plate 43, the inner surface of the opening and closing circular plate 452 is fixedly connected to the outer surface of the first semi-circular tube 463, and the second magnetic block 454 is installed on the inner surface of the connecting plate 43 near the first magnetic block 453.

[0043] During use, when the pressure sensor 466 detects the pressure from the clamping rod 461 and the spring band 465, the pressure sensor 466 is powered by the power supply 468 and the wire 467. However, the power supply 468 will eventually run out of power, so it needs to be replaced when it is depleted. At this time, the opening and closing circular plate 452 is rotated around the outer surface of the fixing rod 451 to overcome the attraction force between the first magnetic block 453 and the second magnetic block 454. Both the first magnetic block 453 and the second magnetic block 454 are strong magnets, which can fix the first semicircular tube 463 and the second semicircular tube 464, and can also be opened manually. Figure 6As shown, the opening and closing circular plate 452 can drive the entire pressing component 46 to separate from the connecting plate 43, revealing a large gap, which facilitates the disassembly of the second semicircular tube 464. After the second semicircular tube 464 is disassembled, it is convenient to replace the power supply 468 inside the first semicircular tube 463. Finally, the second semicircular tube 464 is installed on the outer surface of the first semicircular tube 463.

[0044] Working principle:

[0045] First, the decorative paper is wrapped around the outer surface of the packing tube 35. The decorative paper is then packed by rotating the packing tube 35. During the packing process, the clamping rod 461 is attached to the outer surface of the decorative paper to prevent gaps from forming between the papers during rotation, thus avoiding any issues that could affect the packing effect.

[0046] Secondly, when the first end of the decorative paper first contacts the pressing rod 461, the elastic deformation of the bent rod 462 and the spring band 465 absorbs the squeezing pressure, preventing the decorative paper from detaching from the adhesive tape 36 due to the initial instantaneous contact. At the same time, as the decorative paper continues to wrap around the outer surface of the packing tube 35, the paper thickness is detected by the distance sensor 44, and the distance between the pressing rod 461 and the paper is adjusted by the slide table 42 to ensure that the pressure is always adapted to the current paper condition, avoiding scratches or indentations on the paper surface due to excessive pressure, and also avoiding loose wrapping of the paper due to insufficient pressure.

[0047] Subsequently, by cooperating with the pressure sensor 466 and the clamping rod 461, the pressure is instantly reduced to detect when the decorative paper has finished wrapping. Then, the adhesive plate 47 can be controlled to apply adhesive to the outer surface of the decorative paper, avoiding paper rebound or interlayer loosening caused by the loss of pressure at the end of the clamping rod 461 after resetting. At the same time, if any one of the pressure sensors 466 on both sides of the connecting plate 43 detects that the wrapping is complete, the adhesive can be automatically applied, avoiding the problem of missed adhesive application due to the failure of a single sensor.

[0048] Finally, the two semi-circular tubes are fixed by the strong magnetic attraction of the first magnetic block 453 and the second magnetic block 454. The magnetic separation of the components can be overcome by simply rotating the opening and closing plate 452 manually, without the need for tools. The replacement time of the power supply 468 can be shortened, avoiding the problem that the pressure sensor 466 cannot measure the extrusion pressure of the subsequent decorative paper when the power supply 468 is out of power.
