Description

Technical Field

[0001] This utility model relates to the field of noise reduction barrier technology, specifically a noise reduction barrier for mobile packaging box cardboard production. Background Technology

[0002] In the cardboard production process, high-speed equipment operation and material collisions generate a significant amount of noise. This not only damages workers' hearing health but also, over time, can lead to irritability, difficulty concentrating, and other negative emotions, reducing work efficiency and production quality. Noise barriers effectively block and absorb noise, significantly reducing noise levels inside and outside the workshop, creating a relatively quiet and comfortable working environment for workers and protecting their physical and mental well-being. Simultaneously, reducing noise pollution to the surrounding environment avoids noise disputes with nearby residents, helping companies establish a positive social image and achieve sustainable development.

[0003] The utility model with announcement number CN221895606U discloses a noise reduction structure for a sound barrier. Its structure comprises: a horizontal support, an arc-shaped truss, a vertical support, sound barrier unit panels, a support assembly, a docking assembly, a snap-fit ​​assembly, an installation mechanism, and a push-pull assembly. This utility model, by providing the support assembly, snap-fit ​​assembly, and docking assembly, facilitates installation and disassembly for workers. By providing the installation mechanism and push-pull assembly, workers only need to push the sound barrier unit panels in during installation and push the push-pull rod during disassembly, thus improving the efficiency of installation and disassembly.

[0004] While the aforementioned utility model offers advantages in terms of ease of installation and disassembly, it lacks foldability. In space-constrained environments like paper mills, its large size occupies significant space when not in use or during transport, leading to cramped layouts and hindering the storage and passage of other equipment and materials. Furthermore, its near-immobility makes it difficult to flexibly adjust its position according to the needs of different production areas within the paper mill. Once installed and fixed, any change in noise reduction location requires complete disassembly and reassembly, consuming considerable manpower and time, significantly reducing its ease of use and practicality. Therefore, to address these issues, a mobile noise barrier for packaging cardboard production is proposed. Utility Model Content

[0005] To address the technical problems of noise reduction barriers in comparative technologies, which lack foldability and fail to meet the production needs of paper mills, as well as their poor mobility and inability to meet the requirements for flexible position adjustment, this utility model provides a mobile noise reduction barrier for the production of cardboard packaging boxes.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A noise reduction barrier for mobile packaging cardboard production includes a support frame composed of several arrayed foldable frames, which are fixedly connected as a whole by several sets of longitudinal connecting frames; retractable wheel legs are fixedly installed on the bottom of both sides of each row of foldable frames; wherein, several sets of symmetrically arranged insertion holes are provided on the foldable frames, and barrier plates can be detachably installed on the sides and top of the support frame, and several insertion shafts are fixedly provided on the back of the barrier plates, which are inserted and connected to the insertion holes.

[0007] In one possible implementation, the foldable frame includes two symmetrically arranged pillars, each pillar having a top beam rotatably connected to its top, and the ends of the two top beams being rotatably connected to each other. The two top beams are equipped with matching rotation locking devices for fixing the two top beams together.

[0008] In one possible implementation, the rotating locking element includes two sets of bolt cylinders respectively fixedly disposed at the ends of corresponding top beams, wherein a locking bolt passes through the bolt cylinder and is frictionally connected to the bolt cylinder.

[0009] In one possible implementation, a side connector is fixedly provided on the inner wall of the top of the top beam, which is rotatably connected to the end of the top beam, and the two top beams in each row of foldable frames are rotatably connected by a middle connector.

[0010] In one possible implementation, the retractable wheel outrigger includes an outrigger frame fixedly mounted on the inner wall of the bottom of the support column, wherein a threaded support rod is provided with a threaded connection, and a universal wheel is rotatably connected to the bottom end of the threaded support rod.

[0011] In one possible implementation, the support leg frame has a receiving groove that is wider than the width of the caster wheel, and the top of the caster wheel is machined with a reverse slope.

[0012] In one possible implementation, several sets of symmetrically arranged connecting feet are fixedly installed on both sides of the support column, and the longitudinal connecting frame is made of two intersecting connecting rods welded together, with the two ends of the connecting rods connected to the corresponding connecting feet by bolts.

[0013] In one possible implementation, the barrier plate consists of three parts: a rigid substrate, a porous sound-absorbing plate, and an outer cladding layer, with the three parts arranged sequentially from the inside to the outside.

[0014] In summary, this utility model has the following beneficial technical effects: The foldable frame allows the entire support skeleton to be folded through the rotating connection between the top beam and the support column, as well as the rotating connection between the top beams. When the noise barrier is not needed, it can be quickly disassembled by pulling out the barrier panels, thus folding the support skeleton up. This significantly reduces its space occupation, making it convenient for storage and transportation, and is especially suitable for production workshops with limited space. The design of the retractable wheel outriggers allows the noise reduction barrier to switch between mobile and fixed support modes according to actual needs. Specifically, the omnidirectional wheels facilitate the movement of the noise reduction barrier and can be flexibly adjusted according to changes in the production layout. At the same time, the design of the receiving groove and the ramp allows the omnidirectional wheels to be stored when movement is not required, so that the support column is in direct contact with the ground, increasing the stability of the noise reduction barrier.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2As shown in the figure, this embodiment provides a noise reduction barrier for mobile packaging box cardboard production, including a support frame, which is composed of several arrayed foldable frames 1, and the foldable frames 1 are fixedly connected to each other by several sets of longitudinal connecting frames 2; retractable wheel legs 5, which are fixedly installed on the bottom of both sides of each row of foldable frames 1; wherein, several sets of symmetrically arranged insertion holes 3 are provided on the foldable frames 1, and barrier plates 4 can be detachably installed on the sides and top of the support frame, and several insertion shafts 41 are fixedly provided on the back of the barrier plates 4, which are inserted and connected to the insertion holes 3.

[0018] Based on the above basic scheme, the main support frame is composed of several arrayed and foldable racks 1. The foldable racks 1 are fixedly connected by longitudinal connecting frames 2, which not only ensures the overall stability but also has a folding function, making it convenient for storage and transportation to save space. Retractable wheel legs 5 are fixedly installed on the bottom of both sides of each row of foldable racks 1, which can flexibly switch between fixed support and rolling support working modes to meet different usage needs. Barrier plates 4 can be detachably installed on the sides and top of the support frame. They are connected to the insertion holes 3 on the foldable racks 1 through the insertion shaft 41 on the back of the barrier plate 4, so as to achieve quick installation and disassembly and facilitate maintenance and replacement.

[0019] As a supplement to the specific implementation scheme of the foldable feature of the foldable rack 1, such as Figure 2 As shown, the foldable rack 1 includes two symmetrically arranged support columns 11. Each support column 11 is rotatably connected to a top beam 12, and the ends of the two top beams 12 are rotatably connected to each other. The two top beams 12 are equipped with matching rotating locking parts 13, which are used to fix the two top beams 12 together. The inner wall of the top of the top beam 12 is fixedly provided with a side connecting part 14, which is rotatably connected to the end of the top beam 12. The two top beams 12 in each row of foldable racks 1 are rotatably connected by a middle connecting part 15. The above scheme can ensure the reliability of the overall rotating connection of the foldable rack 1, providing the necessary structural foundation for its rotation and folding. At the same time, the rotating locking part 13 can keep the foldable rack 1 in a stable support state during operation, so that it has the load-bearing capacity.

[0020] Among them, such as Figure 4 As shown, the rotating locking component 13 includes two sets of bolt cylinders 131 respectively fixedly installed at the ends of the corresponding top beam 12. A locking bolt 132 is inserted into the bolt cylinder 131. The locking bolt 132 is frictionally connected to the bolt cylinder 131. Based on the above structure, the top beam 12 is fixed and unlocked by the insertion, removal and friction of the locking bolt 132 in the bolt cylinder 131.

[0021] like Figure 3As shown, the retractable wheel support leg 5 includes a support leg frame 51 fixedly installed on the inner wall of the bottom of the support column 11, wherein a threaded support rod 52 is provided with a threaded connection, and a universal wheel 53 is rotatably connected to the bottom end of the threaded support rod 52. The support leg frame 51 has a receiving groove 55, the width of which is wider than the width of the universal wheel 53, and the top of the universal wheel 53 is machined with a reverse slope 54. The above structural design allows the noise reduction barrier to switch between two modes of mobile support and fixed support according to actual needs. Specifically, the universal wheel 53 facilitates the movement of the noise reduction barrier and can flexibly adjust its position according to changes in the production layout. At the same time, the design of the receiving groove 55 and the reverse slope 54 allows the universal wheel 53 to be stored when it is not needed, so that the support column 11 directly contacts the ground, increasing the stability of the noise reduction barrier.

[0022] like Figure 2 - Figure 3 As shown, several sets of symmetrically arranged connecting legs 16 are fixedly installed on both sides of the support column 11. The longitudinal connecting frame 2 is made of two cross connecting rods welded together, and the two ends of the connecting rods are bolted to the corresponding connecting legs 16. The longitudinal connecting frame 2 connects multiple foldable frames 1 into an integral support frame, thereby enhancing the stability of the structure.

[0023] In addition, the barrier plate 4 is composed of three parts: a rigid substrate, a porous sound-absorbing plate, and an outer cladding layer. These three parts are arranged sequentially from the inside to the outside. In the above structure, the porous sound-absorbing plate can effectively absorb the noise generated during the production of packaging box cardboard, the rigid substrate ensures the structural strength of the barrier plate 4, and the outer cladding layer improves its durability and aesthetics. The overall noise reduction effect is significant.

[0024] The working principle and usage process of this utility model: During the production of cardboard packaging boxes, the assembled noise reduction barriers are moved to the areas requiring noise reduction, and their positions are adjusted according to the production layout. When the noise reduction barrier needs to be moved, it is pushed, and the casters 53 allow for flexible movement. Once moved to the designated position, if the ground is uneven, the threaded support rod 52 can be rotated to adjust the height of the telescopic wheel legs 5, ensuring the noise reduction barrier remains stable. During production, the barrier panels 4 effectively absorb and isolate noise generated by the equipment, creating a relatively quiet working environment for the staff.

[0025] When the noise barrier is not needed, first remove the barrier panel 4 from the support frame by gently pulling out the connector shaft 41. Then loosen the bolts between the longitudinal connecting frame 2 and the connecting leg 16 and remove the longitudinal connecting frame 2. Next, pull out the locking bolt 132 to unlock the top beam 12 and fold the foldable frame 1 to reduce its space occupation. Finally, organize and store the folded foldable frame 1 and the disassembled parts for future use.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
