[0004] The aforementioned patent places corrugated paper on a conveyor belt for dust removal. However, it is difficult to clean the bottom surface of the corrugated paper thoroughly during the dust removal process. To address the aforementioned technical shortcomings, we propose a high-efficiency dust removal device for the clean production of corrugated cardboard boxes. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency dust removal device for the cleaning production of corrugated cardboard boxes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency dust removal device for cleaning corrugated cardboard box production includes a corrugated cardboard dust removal box and a dust removal assembly. Conveying rollers are symmetrically and rotatably installed inside the corrugated cardboard dust removal box. The dust removal assembly includes two symmetrically arranged rotating rollers rotatably mounted on the inner wall of the corrugated cardboard dust removal box. Long brushes are evenly distributed on the outer wall of the rotating rollers. An exhaust pipe is fixedly installed on the outer wall of the corrugated cardboard dust removal box, and the exhaust pipe is connected to the inner side of the box. An exhaust fan is fixedly installed at the outer end of the exhaust pipe, and a dust filter is installed at the exhaust fan's air outlet. A dust collection box is connected to the lower side of the exhaust pipe, and a door is rotatably installed on the side of the dust collection box.

[0008] Furthermore, a central support assembly is provided at the middle position of the two rollers. The central support assembly includes a mounting side plate, which is screwed onto the inner wall of the corrugated paper dust collector. A connecting rod is fixedly installed on the side of the mounting side plate, and a central support connecting rod is fixedly connected to the end of the connecting rod.

[0009] Furthermore, both ends of the intermediate support connecting rod are connected to the side of the conveyor roller, but the two ends of the intermediate support connecting rod do not contact the side of the conveyor roller.

[0010] Furthermore, the rotating rollers are symmetrically distributed along the upper and lower sides of the central bearing connecting rod.

[0011] Furthermore, the corrugated paper dust collector has openings on both sides, and a connecting plate is fixedly installed inside the opening, with the connecting plate close to the side of the conveyor roller.

[0012] Furthermore, a protective cover is installed on the outer wall of the corrugated paper dust collector, and a drive assembly is provided inside the protective cover.

[0015] Compared with related technologies, the high-efficiency dust removal device for the cleaning production of corrugated cardboard boxes proposed in this utility model has the following beneficial effects:

[0016] This utility model describes a high-efficiency dust removal device for cleaning corrugated cardboard boxes. Through its dust removal components, when corrugated paper is conveyed inside the corrugated paper dust removal box, it is positioned between two rotating rollers. As the rollers rotate, the long-bristled brushes on their outer sides directly contact the upper and lower sides of the corrugated paper, sweeping up dust. At this time, an exhaust fan is activated, drawing the dust into the exhaust cylinder. The dust then slides down through the exhaust fan's filter screen and is collected in the lower dust collection box. Through the coordinated action of the components in the dust removal assembly, the upper and lower sides of the corrugated paper are simultaneously dusted, resulting in a more thorough dust removal effect and enhanced practicality.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-5A high-efficiency dust removal device for the cleaning production of corrugated cardboard boxes includes a corrugated cardboard dust removal box 1 and a dust removal component 4. Conveying rollers 7 are symmetrically and rotatably installed on the inner side of the corrugated cardboard dust removal box 1. The dust removal component 4 includes two symmetrically arranged rotating rollers 45, which are rotatably installed on the inner wall of the corrugated cardboard dust removal box 1. Long brushes 46 are evenly distributed on the outer wall of the rotating rollers 45. An exhaust cylinder 41 is fixedly installed on the outer wall of the corrugated cardboard dust removal box 1, and the exhaust cylinder 41 is connected to the inner side of the corrugated cardboard dust removal box 1. An exhaust fan 44 is fixedly installed at the outer end of the exhaust cylinder 41, and a dust filter screen is provided at the air outlet of the exhaust fan 44. A dust collection box 42 is connected and installed below the exhaust cylinder 41, and a door 43 is rotatably installed on the side of the dust collection box 42.

[0025] In this method, a central support assembly 8 is provided at the middle position of the two rotating rollers 45. The central support assembly 8 includes a mounting side plate 81, which is screwed onto the inner wall of the corrugated paper dust collector 1. A connecting rod 82 is fixedly installed on the side of the mounting side plate 81, and a central support connecting rod 83 is fixedly connected to the end of the connecting rod 82. The two ends of the central support connecting rod 83 are connected to the side of the conveying roller 7, but the two ends of the central support connecting rod 83 do not contact the side of the conveying roller 7.

[0026] With the above-mentioned arrangement, the function of the connecting rod 83 is to guide the corrugated paper conveyed by the corrugated paper dust collector 1 from one side of the conveying roller 7 to the other side of the conveying roller 7, so that a gap is left between the two conveying rollers 7 to provide a working area for dust removal.

[0027] In this configuration, the rollers 45 are symmetrically distributed along the upper and lower sides of the connecting rod 83.

[0028] With the above configuration, the rollers 45 are symmetrically distributed along the upper and lower sides of the connecting rod 83. When the corrugated paper is conveyed on the upper side of the connecting rod 83, the long brushes 46 on the outer wall of the rollers 45 can directly and synchronously sweep the upper and lower sides of the corrugated paper, which facilitates synchronous cleaning of the upper and lower sides of the corrugated paper and improves dust removal efficiency.

[0029] In this method, the corrugated paper dust collector 1 has openings 3 on both sides, and a connecting plate 31 is fixedly installed inside the opening 3. The connecting plate 31 is close to the side of the conveying roller 7.

[0030] By setting up the connecting plate 31 in the above manner, a support and guide channel is formed between the through-hole 3 and the conveying roller 7.

[0031] In this method, a protective cover 5 is installed on the outer wall of the corrugated paper dust collection box 1, and a drive assembly 6 is provided inside the protective cover 5.

[0032] By setting up the protective cover 5 in the above manner, the drive component 6 inside can maintain a stable working environment.

[0033] In this configuration, the drive assembly 6 includes two first rotating shafts 61. A first gear 62 is fixedly mounted on the outer end of the first rotating shaft 61. A drive motor 63 is fixedly mounted on the outer wall of the corrugated paper dust collector 1. A drive gear 64 is fixedly mounted on the output end of the drive motor 63. A toothed belt 65 is fitted around the outer sides of the drive gear 64 and the first gear 62. Two second gears 67 are sequentially meshed on the lower side of the drive gear 64. A second rotating shaft 66 is fixedly mounted on the inner side of the second gear 67. The second rotating shaft 66 rotates through to the inner side of the corrugated paper dust collector 1 and is connected to the shaft coupling of the rotating roller 45. The first rotating shaft 61 rotates through to the inner side of the corrugated paper dust collector 1 and is connected to the shaft coupling of the conveying roller 7.

[0034] With the above configuration, when the drive motor 63 rotates, it drives the drive gear 64 to rotate, which in turn drives the two first gears 62 to rotate synchronously via the toothed belt. This, in turn, drives the two inner conveying rollers 7 to rotate synchronously via the two first rotating shafts 61 for conveying the corrugated paper. In addition, the drive gear 64 can also mesh synchronously to drive the two lower second gears 67 to rotate synchronously via the second rotating shaft 66, which in turn drives the two inner rollers 45 to rotate, thereby driving the long brushes 46 on the outer side of the rollers 45 to rotate and sweep.

[0035] In this method, a controller 2 is fixedly installed on the outer wall of the corrugated paper dust collection box 1. The controller 2 is electrically connected to the exhaust fan 44 and the drive motor 63 respectively.

[0036] With the above settings, controller 2 can control the working status of exhaust fan 44 and drive motor 63.

[0037] The working principle of the high-efficiency dust removal device for cleaning corrugated cardboard boxes provided by this utility model is as follows:

[0038] In use, corrugated paper is fed into the inside of the corrugated paper dust collector 1 through the inlet 3 for dust removal. The exhaust fan 44 and drive motor 63 are started synchronously by the controller 2. Driven by the drive motor 63, the conveying roller 7 and rotating roller 45 inside the corrugated paper dust collector 1 are driven synchronously by the drive assembly 6. The rotating roller 7 provides the conveying power for the corrugated paper in the corrugated paper dust collector 1. The rotating roller 45 drives the long brush 46 on the outer side to perform synchronous brushing work with the upper and lower sides of the corrugated paper. At the same time, the suction of the exhaust fan 44 can suck the dust into the inside of the exhaust cylinder 41. The dust falls into the dust collection box 42 below the exhaust fan 44 after being blocked by the dust filter screen. When a lot of dust accumulates in the dust collection box 42, the box door 43 can be opened to clean the dust inside the dust collection box 42.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
