[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A paper surface dust removal device for corrugated paper production, combined with Figures 1 to 2 As shown, the machine includes a frame 1, on which a feeding conveyor belt 2, a dust removal box 3, and a discharging conveyor belt 7 are arranged sequentially from left to right. The feeding conveyor belt 2 is used to feed paper into the dust removal box 3; the dust removal box 3 is used to remove dust from the paper; and the discharging conveyor belt 7 is used to transport the dust-removed paper to the next process.

[0018] The dust collector 3 has an inlet 31 and an outlet 32 ​​on its left and right side walls, respectively. The inlet 31 is opposite to the outlet end of the inlet conveyor belt 2, and the outlet 32 ​​is opposite to the inlet end of the outlet conveyor belt 7. The dust collector 3 contains a dust removal mechanism 4 and a traction mechanism 5. The dust removal mechanism 4 is located near the inlet 31 and is used to remove dust from both the upper and lower surfaces of the paper simultaneously. The traction mechanism 5 is located to one side of the dust removal mechanism 4 and near the outlet 32, and is used to traction the paper. The dust collector 3 is also connected to a filter dust collection mechanism 6, which is used to filter and collect dust.

[0019] The dust removal mechanism 4 includes a lower dust removal component 41 and an upper dust removal component 42 disposed within the dust removal box 3. The lower dust removal component 41 is disposed at the bottom of the dust removal box 3 and is used to remove dust from the lower surface of the paper. The upper dust removal component 42 is located directly above the lower dust removal component 41 and is used to remove dust from the upper surface of the paper. A first lifting drive component 49 is connected to the top of the upper dust removal component 42. The first lifting drive component 49 is used to drive the upper dust removal component 42 away from and closer to the lower dust removal component 41, thereby making it suitable for dust removal of paper of different thicknesses.

[0020] The lower dust removal assembly 41 and the upper dust removal assembly 42 have the same structure and are arranged in a mirror image symmetrically. Each assembly includes a mounting box 43. Several dust removal brushes 44 are mounted on the box plate facing the paper. The side of each dust removal brush 44 facing the paper has bristles 45, and the side away from the paper has a brush shaft 46 that passes through the mounting box 43 and is rotatably mounted to it. Inside the mounting box 43 is a gear transmission assembly 47 fixedly connected to each brush shaft 46. The gear transmission assembly 47 includes several gears that mesh sequentially. A dust removal drive motor 48 is also located inside the mounting box 43. The dust removal drive motor 48 is connected to a brush shaft 46. When the dust removal drive motor 48 drives the connected brush shaft 46, it drives each dust removal brush 44 to rotate via the gear transmission assembly 47. The rotating dust removal brushes 44 remove dust from the paper surface through the bristles 45 that contact the paper surface, effectively ensuring the dust removal effect.

[0021] The first lifting drive assembly 49 includes a telescopic cylinder 491 located at the top of the dust collector 3. The telescopic rod of the telescopic cylinder 491 is positioned downwards and fixedly connected to the mounting box 43 of the upper dust collector assembly 42, thereby driving the upper dust collector assembly 42 away from and closer to the lower dust collector assembly 41. Guide sleeves 492 are respectively provided on the front and rear sides of the telescopic cylinder 491. The top of the guide sleeve 492 is fixedly connected to the top of the dust collector 3. A guide rod 493 is slidably fitted inside the guide sleeve 492. The bottom of the guide rod 493 protrudes from the guide sleeve 492 and is fixedly connected to the mounting box 43 of the upper dust collector assembly 42. When the first lifting drive assembly 49 drives the upper dust collector assembly 42 away from and closer to the lower dust collector assembly 41, the guide sleeve 492 and the guide rod 493 cooperate to provide good guidance and achieve smooth lifting.

[0022] like Figures 3 to 4 As shown, the dust removal brush 44 is circular, and several dust removal brushes 44 are arranged in two rows. The dust removal brushes 44 in each row are spaced apart along the direction perpendicular to the paper conveying direction, and the distance between the spaces is less than the diameter of the dust removal brush 44. One row of dust removal brushes 44 is embedded in the gap between the other row of dust removal brushes 44. This design can effectively ensure the comprehensive dust removal of the paper surface.

[0023] The dust collection and filtration mechanism 6 includes a suction port 61 located on the rear panel of the dust collection box 3. The suction port 61 is positioned opposite to the dust removal brush 44, and the suction port 61 is connected to a suction box 62 located on the outside of the rear panel of the dust collection box 3. Figure 5 As shown, the bottom of the dust collection box 62 is open and covered with a dust extraction fan 64; a dust collection drawer 65 is slidably installed inside the dust collection box 62, located above the dust extraction fan 64 and can be pulled outwards, and the bottom of the dust collection drawer 65 is open and covered with a dust filter 63. When the dust removal mechanism 4 removes dust from the paper surface, the dust extraction fan 64 operates, drawing out the raised dust through the suction port 61. The drawn-out dust is filtered by the dust filter 63 and remains in the dust collection drawer 65; when it is necessary to clean the dust, the dust collection drawer 65 can be pulled out and the dust emptied.

[0024] The traction mechanism 5 includes a lower traction roller 51, an upper traction roller 54, and a second lifting drive assembly 53.

[0025] The lower traction roller 51 is located on one side of the lower dust removal assembly 41. Both ends of the lower traction roller 51 are rotatably connected to the front and rear boxes of the dust removal box 3. One end of the lower traction roller 51 extends out of the dust removal box 3 and is connected to the lower traction drive motor 52. The lower traction drive motor 52 is set on the side wall of the dust removal box 3 and is used to drive the lower traction roller 51 to rotate.

[0026] The second lifting drive assembly 53 is located at the top inside the dust collection box 3, and the structure of the second lifting drive assembly 53 is the same as that of the first lifting drive assembly 49. For example... Figure 6 As shown, a mounting frame 56 is provided at the bottom of the second lifting drive assembly 53. The upper traction roller 54 is rotatably mounted on the mounting frame 56, and is arranged parallel to and directly above the lower traction roller 51. One end of the upper traction roller 54 is connected to an upper traction drive motor 55 mounted on the mounting frame 56. The upper traction drive motor 55 drives the upper traction roller 54 to rotate, and the rotation direction of the upper traction roller 54 is opposite to that of the lower traction roller 51, which can provide traction for the paper. At the same time, the upper traction roller 54 moves away from and closer to the lower traction roller 51 under the drive of the second lifting drive assembly 53, thus making it suitable for traction of paper of different thicknesses.

[0027] In use, according to the paper thickness, the upper dust removal component 42 is adjusted to a suitable height by the first lifting drive component 49, and the upper traction roller 54 is adjusted to a suitable height by the second lifting drive component 53. The feeding conveyor belt 2 feeds the paper into the dust removal box 3 located between the upper dust removal component 42 and the lower dust removal component 41. At the same time, the dust removal brushes 44 on the upper dust removal component 42 and the lower dust removal component 41 rotate, and the brush bristles 45 make full contact with the upper and lower surfaces of the paper, removing dust from the upper and lower surfaces of the paper simultaneously. The dust extraction fan 64 generates negative pressure, and the dust enters the dust collection drawer 65 through the dust suction port 61 for temporary storage. As the paper is continuously conveyed, it enters the traction mechanism 5, and the upper traction roller 54 and the lower traction roller 51 rotate in opposite directions, forming a clamping force to drive the paper out and into the discharge conveyor belt 7 for transfer to the next process.
