[0029] This utility model of a pre-printing dust removal device for cardboard surfaces achieves efficient, reliable, and automated one-time dust removal on both the upper and lower sides of the cardboard through a dust removal roller 3, an upper roller brush assembly 5 that can precisely adhere and detach, and a guide channel 41 on the mounting frame 4. The lower dust removal roller 3 and the transport device 2 are integrated and installed inside the housing 1. This arrangement saves space and makes full use of the space in the housing 1, resulting in a more compact overall structure. The dust removal roller 3 extends directly through the notch 201 on the transport device 2 and contacts the lower surface of the cardboard, ensuring that the dust removal roller 3 can act stably, reliably, and directly on the lower surface of the cardboard. The drive assembly 6 can control the rotation of the roller brush assembly 5 relative to the mounting frame 4, so that it can precisely adhere to the upper surface of the cardboard according to the thickness and surface condition of the cardboard, ensuring that the roller brush pressure is moderate and achieving the best dust removal effect.

[0030] The transport device 2 includes a support plate 21 detachably connected to the housing 1. The support plate 21 is provided with a connecting plate 22 that can be inserted into the housing 1. A plurality of first rotating rollers 23 are spaced apart on the connecting plate 22. A conveyor belt 24 is provided between the plurality of first rotating rollers 23. The connecting plate 22 is also provided with a first drive motor 25 that can be rotatably connected to any of the plurality of first rotating rollers 23. The support plate 21 is provided with the notch 201 so that the dust removal roller 3 can partially extend above the support plate 21.

[0031] The support plate 21 is detachably connected to the housing 1, allowing the entire transport device 2 to be assembled and disassembled as a single module. The connecting plate 22 is mounted on the support plate 21 and snaps into the housing 1, making full use of the internal space of the housing 1. The first drive motor 25 and multiple first rotating rollers 23 are all mounted on the connecting plate 22, resulting in a compact layout and reducing the occupancy of external space. The notch 201 is designed to facilitate contact between the dust removal roller 3 and the lower surface of the cardboard.

[0032] The dust removal roller 3 includes a bracket 31 connected to a connecting plate 22. Multiple second rotating rollers 32 are arranged on one side of the bracket 31. A roller body 33 is also mounted on the bracket 31. The conveyor belt 24 is connected to the multiple second rotating rollers 32 to keep the conveyor belt 24 taut. A second drive motor 34 is also mounted on the connecting plate 22. A pulley assembly 35 capable of driving the roller body 33 is arranged between the second drive motor 34 and the roller body 33. The dust removal roller 3 is directly connected to the connecting plate 22 via the bracket 31, resulting in a high degree of integration between the dust removal roller 3 and the conveyor device 2. This design integrates the conveyor belt 24, the first rotating roller 23, the second rotating rollers 32, and the roller body 33 onto the connecting plate 22, making the overall structure more compact and occupying less space. The conveyor belt 24 forms a closed loop by connecting the first rotating roller 23 and the second rotating roller 32. The position of the second rotating roller 32 effectively tensions the conveyor belt 24, ensuring it remains taut during operation and preventing slippage, deviation, or slackness, thus significantly improving the stability and reliability of material conveying. After the second drive motor 34 starts, its output shaft drives the pulley assembly 35, which in turn drives the roller body 33 to roll, thereby brushing the lower surface of the cardboard to remove dust.

[0033] The dust removal roller 3 also includes an air jet component 36 disposed on the connection. The air jet component 36 is provided with a ventilation chamber 361, and an air inlet 362 at the bottom of the air jet component 36 that communicates with the ventilation chamber 361.

[0035] The mounting bracket 4 includes two uprights 42 spaced apart on the left and right sides. The two uprights 42 are connected by multiple crossbars 43. Multiple sliders 44 that can slide along the crossbars 43 on the same side are provided. A mounting plate 45 is provided between the multiple sliders 44. The drive assembly 6 is mounted on the mounting plate 45. The sliders 44 can slide along the crossbars 43, so that the mounting plate 45 and the drive assembly 6 thereon can be precisely adjusted in the horizontal direction. The sliders 44 can be fixed by tightening or loosening the screws.

[0036] The drive assembly 6 includes a rotating frame 61 rotatably connected to the mounting plate 45. The rotating frame 61 is provided with a plurality of mounting brackets 62. The rotating frame 61 is also provided with an upwardly extending extension 611. Multiple sliders 44 away from the rotating frame 61 are also provided with mounting seats 63.

[0037] When the position of the roller brush assembly 5 needs to be adjusted, the cylinder 64 is activated, and the output shaft of the cylinder 64 drives the extension 611 to move. At this time, the rotating frame 61 can rotate relative to the multiple sliders 44. During the rotation, the roller brush assembly 5 on the mounting bracket 62 gradually moves away from or closer to the upper surface of the cardboard, adjusting the pressure on the upper surface of the cardboard.

[0038] The roller brush assembly 5 includes a connecting frame 51 that can be connected to a mounting bracket 62. A third drive motor 52 is located at the end of the connecting frame 51. The output shaft of the third drive motor 52 is connected to a rotating disk 53 that can rotate with it. Multiple brush sections 54 are provided on the rotating disk 53. The multiple brush sections 54 on the rotating disk 53 allow the brush sections 54 to cover a larger cleaning area during rotation, thus improving cleaning efficiency.

[0039] The rotating disk 53 is provided with multiple mounting slots 531, and multiple brush parts 54 are detachably connected to the rotating disk 53 through the multiple mounting slots 531. Through the mounting slots 531, users can quickly replace damaged brush parts 54 without replacing the entire rotating disk 53 or the roller brush assembly 5, reducing the cost of use. At the same time, depending on the thickness and strength of the cardboard, softer or moderately hard brush parts 54 can be replaced, making it more applicable to a wider range of applications.

[0040] The housing 1 is also provided with a plurality of guide components 8, which are located on the inlet side and the outlet side of the transport device 2. Each guide component 8 includes a rotating plate 81 rotatably connected to the housing. The rotating plate 81 is provided with a plurality of slots 811. The rotating plate 81 is also provided with a transmission rod 82 that is engaged with the rotating plate 81 through the slots 811. The transmission rod 82 is provided with a plurality of transmission wheels 83 that can contact the lower surface of the cardboard. A support component 9 is provided between the rotating plate 81 and the housing to adjust the tilt angle of the rotating plate 81 relative to the guide components 8.

[0041] Through the rotating connection design of the rotating plate 81, and in conjunction with the tilt angle adjustment of the support component 9, the guide component 8 can adjust the inlet / outlet guide angle according to the thickness and warpage of the cardboard. The transmission wheel 83 rolls in contact with the lower surface of the cardboard, forming a rotation, thus avoiding the scratching of the lower surface of the cardboard by the traditional fixed guide plate.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
