DETAILED DESCRIPTION

[0026] like Figures 1 to 4 As shown, a printing paper dust removal device includes a sticking roller 12 arranged between two conveying rollers 2, and conveying support seats 1 are arranged at both ends of the conveying rollers 2. The ends of the conveying rollers 2 are abutted against the two sides of the conveying support seats 1 through bearings to rotate;

[0027] A mounting seat 3 is fixed on the conveying support seat 1, and a bearing seat 8 that slides up and down is arranged in the mounting seat 3. Both ends of the adhesive roller 12 are against the bearing seat 8 through a coupling 10. A cover plate 4 is fixed on the top of the mounting seat 3, and a screw 5 is arranged in the cover plate 4. The end of the screw 5 is against the bearing seat 8 for rotation. A spring 7 is sleeved on the screw 5, and one end of the spring 7 is against the cover plate 4, and the other end is against the bearing seat 8.

[0028] The printing paper is transported on the conveying roller 2, and the sticky roller 12 is pressed against the printing paper to adhere to clean dust. The two ends of the sticky roller 12 are always downward under the pushing action of the spring 7, so that the sticky roller 12 can rotate closely against the printing paper, thereby achieving the purpose of dust removal. The sticky roller 12 is connected by a coupling 10, which can be quickly disassembled and replaced.

[0029] The conveying roller 2 is used to carry and convey paper. The conveying support seat 1 fixes the position of the conveying roller 2 and supports its rotation. The sticking roller 12 contacts the paper, absorbs and removes dust and impurities on the surface of the paper. The mounting seat 3 is fixed on the conveying support seat 1, and is used to install and adjust the position of the sticking roller 12. The bearing seat 8 is connected to the mounting seat 3, and the end of the sticking roller 12 is accommodated inside, allowing it to slide up and down. The cover plate 4 is fixed on the top of the mounting seat 3 to protect the internal structure. The screw 5 passes through the cover plate 4 and is connected to the bearing seat 8, which is used to adjust the pressure of the sticking roller 12. The spring 7 is located around the screw 5, one end of which is against the cover plate 4 and the other end is against the bearing seat 8, providing continuous pressure to the sticking roller 12. The coupling 10 connects the sticking roller 12 and the bearing seat 8 to facilitate the installation, disassembly and replacement of the sticking roller 12.

[0030] The printed paper passes between the conveying rollers 2. The sticky roller 12 is pressed against the surface of the paper under the action of the spring 7 and rotates as the paper moves. The surface material of the sticky roller 12 has a certain viscosity and can absorb dust and impurities on the surface of the paper. By adjusting the screw 5, the pressure of the spring 7 can be changed, thereby controlling the pressure of the sticky roller 12 on the paper, ensuring the dust removal effect while reducing damage to the paper.

[0031] The pressure of the sticking roller 12 on the paper can be adjusted as needed by the combination of the screw 5 and the spring 7. The design of the coupling 10 makes the sticking roller 12 easy to install and disassemble, and convenient for regular cleaning or replacement.

When the adhesive roller 12 needs to be replaced, the screw rod 5 is lifted and rotated so that the threaded shaft 501 is threaded with the internal threaded barrel 401, so that the adhesive roller 12 can be lifted up to have enough space for personnel to operate. By matching the threaded shaft 501 at the end of the screw rod 5 with the internal threaded barrel 401 at the bottom of the cover plate 4, the adhesive roller 12 can be easily lifted without disassembling other components, which is convenient for replacement or cleaning.

[0034] Preferably, slide rails 9 are fixedly arranged on both sides of the interior of the mounting seat 3, and the two sides of the bearing seat 8 slide against the slide rails 9 through sliders. The two sides of the bearing seat 8 abut against the mounting seat 3 through the sliding assembly, and the sliding is smoother and more reliable.

[0035] Preferably, a connecting seat 801 is fixed on the top of the bearing seat 8, and the end bearing of the screw 5 abuts against and rotates in the connecting seat 801. The screw 5 can rotate freely, and rotating the screw 5 can connect the threaded shaft 501 with the internal threaded barrel 401, which is convenient for replacing the adhesive roller 12.

[0036] Preferably, an optical axis 1001 is fixedly provided at one end of the coupling 10, and a U-shaped hoop 1002 is fixedly provided at the other end, the optical axis 1001 abuts against the inside of the bearing seat 8, through holes 1003 are provided on both sides of the U-shaped hoop 1002, the main shaft of the sticky roller 12 abuts against the inside of the U-shaped hoop 1002, and the locking bolt 11 passes through the through hole 1003 and the main shaft of the sticky roller 12, thereby connecting and fixing the two.
