Description

Technical Field

[0001] This application relates to the field of paper embossing device technology, and more specifically, to a paper embossing roller cleaning structure. Background Technology

[0002] Paper used in daily life, including toilet paper, facial tissues, and napkins, is mostly made of two or more layers of paper. In order to prevent the layers from peeling off easily during use, paper processing equipment is generally equipped with embossing rollers to emboss the multi-layered paper. The embossed patterns make it less likely for the multi-layered paper to peel off during use.

[0003] When embossing paper, paper scraps and residues easily adhere to the surface of the embossing roller. If these residues are not cleaned in time, they will be pressed back into the paper surface by the embossing roller, forming white spots or causing localized bulges in the paper, resulting in substandard paper appearance quality.

[0004] Some embossing rollers have a cleaning component on the outside to clean paper residue on the embossing roller. However, paper residue adhering to the cleaning component also needs to be cleaned in time. Otherwise, the paper residue on the cleaning component will stick to the embossing roller, or the cleaning effect on the embossing roller will be reduced. Utility Model Content

[0034] Reference Figure 1-6 ,

[0035] A paper embossing roller cleaning structure is characterized by comprising: a driving component 1, a fixing frame 2, an embossing roller 21, a cleaning roller 22, and a scraper 24; the driving component 1 is a servo motor or a drive motor, preferably a drive motor in this embodiment. The embossing roller 21, the cleaning roller 22, and the scraper 24 are all fixedly mounted on the fixing frame 2; specifically, the cleaning structure also includes a pressure roller, the rotation direction of which is different from that of the embossing roller 21, and the paper passes between the pressure roller and the embossing roller 21. The pressure roller and the embossing roller 21 cooperate to emboss patterns on the paper. The driving component 1 drives the cleaning roller 22 to rotate. The outer wall surface of the cleaning roller 22 is provided with bristles 232, which contact the outer wall surface of the embossing roller 21. The cleaning roller 22 is located on the side of the embossing roller 21 away from the paper. The scraper 24 is located on the side of the cleaning roller 22 away from the embossing roller 21. Specifically, after the embossing roller 21 engages with the pressure roller, paper residue adheres to the embossing roller 21. The cleaning roller 22 rotates in the opposite direction to the embossing roller 21. After the bristles 232 on the cleaning roller 22 contact the outer wall surface of the embossing roller 21, the bristles 232 can clean the paper residue from the embossing roller 21. The scraper 24 is provided with multiple scraping parts 241, which are block-shaped structures. In other embodiments, the scraping parts 241 are rod-shaped structures. Gaps are provided between the multiple scraping parts 241, forming a comb-like structure. The end of the scraping part 241 facing the cleaning roller 22 contacts the cleaning roller 22. The drive unit 1 can drive the cleaning roller 22 to rotate, and the bristles 232 provided on the cleaning roller 22 can clean the paper scraps and residues on the embossing roller 21, preventing the paper scraps from being pressed back into the paper to form white spots or bumps, reducing paper appearance defects, and improving the quality pass rate of the embossed paper. The scraper 24, which is provided on one side of the cleaning roller 22 and has multiple scraper parts 241 with gaps between the scraper parts 241, can promptly scrape off the paper scraps and residues adhering to the bristles 232 of the cleaning roller 22, preventing them from secondary contaminating the embossing roller 21 or reducing the cleaning effect.

[0036] Specifically, the cleaning structure also includes a mounting plate 23. The mounting plate 23 is provided with bristles 232; the side of the mounting plate 23 facing away from the bristles 232 contacts the outer wall surface of the embossing roller 21. In this embodiment, the side of the mounting plate 23 facing away from the bristles 232 makes surface contact with the outer wall surface of the embossing roller 21. At least two mounting plates 23 are provided. In this embodiment, four mounting plates 23 are provided. Because the bristles 232 are in long-term contact with the outer wall surface of the embossing roller 21, friction causes the bristles 232 to fall off, reducing their number and consequently decreasing their cleaning effect on the embossing roller 21. Therefore, in this embodiment, the mounting plate 23 and the embossing roller 21 are detachably connected so that the mounting plate 23 can be replaced when the cleanliness of the bristles 232 on the embossing roller 21 decreases.

[0037] Specifically, the mounting plate 23 has mounting portions 231 at both ends, and the mounting portions 231 are block-shaped structures. Specifically, the cleaning roller 22 has journals at both ends for mounting bearings. The diameter of the journals is smaller than the diameter of the cleaning roller 22 body. The mounting portions 231 are disposed on the journals to prevent the mounting portions 231 from contacting the outer wall surface of the printing roller when the cleaning roller 22 rotates. The side of the mounting portion 231 facing the cleaning roller 22 is in contact with the cleaning roller 22. In this embodiment, the side of the mounting portion 231 facing the cleaning roller 22 is in surface contact with the cleaning roller 22. The mounting portion 231 has mounting holes 2311; the cleaning roller 22 has threaded holes 222 at both ends that match the diameter of the mounting holes 2311. A bolt passes through the mounting holes 2311 and is threaded into the threaded holes 222 to fix the mounting plate 23 to the cleaning roller 22. In other embodiments, the mounting plate 23 is fixed to the cleaning roller 22 by a detachable snap-fit ​​structure.

[0038] Specifically, the cleaning roller 22 has positioning parts 221 at both ends, and the positioning parts 221 are block structures. The positioning parts 221 are located on both sides of the threaded hole 222; when the mounting part 231 contacts the positioning parts 221, the mounting hole 2311 is coaxial with the threaded hole 222. The positioning parts 221 can guide the mounting part 231 to be accurately positioned, so as to ensure that the mounting hole 2311 and the threaded hole 222 are automatically coaxial, thereby improving assembly efficiency.

[0039] Specifically, the end of the scraper 24 furthest from the scraper part 241 is rotatably connected to the mounting frame 2. The operator can adjust the rotation of the scraper 24 to move the scraper part 241 away from the cleaning roller 22, providing more space for the operator to install or remove the mounting plate 23. Specifically, when cleaning the cleaning roller 22 is required, the operator can hold the scraper 24 and rotate it relative to the mounting frame 2, allowing the scraper part 241 to insert into the bristles 232. As the cleaning roller 22 rotates, the mounting plate 23 also rotates, and the scraper part 241 cleans the bristles 232.

[0040] Specifically, the scraper 241 has a guide surface 2411 and a scraping surface 2412. Paper scraps at the junction of the bristles 232 and the mounting plate 23 are the most difficult to clean. The scraping surface 2412, being tangent to the outer wall of the cleaning roller 22, allows the scraper 241 to be fully inserted into the bristles 232 to clean the paper scraps. The end of the guide surface 2411 facing the cleaning roller 22 is connected to the scraping surface 2412, and the guide surface 2411 and the scraping surface 2412 form an angle of 15-45°. In this embodiment, the guide surface 2411 and the scraping surface 2412 form a 15° angle, and the guide surface 2411 is designed to allow the scraper 241 to easily insert into the bristles 232.

[0041] Specifically, the scraper 24 also includes a pressure bar 242; the pressure bar 242 is inserted through the scraper section 241 along the length of the scraper 24. When the scraper section 241 is inserted into the bristles 232, the pressure bar 242 will contact the bristles 232. As the cleaning roller 22 rolls, the pressure bar 242 will gradually scrape from the root of the bristles 232 toward the end of the bristles 232 away from the cleaning roller 22. The pressure bar 242 can scrape off the paper residue adhering to the root of the bristles 232.

[0042] Specifically, the scraper 24 also includes: a cleaning block 243, a connecting pipe 244, and an air pump 245. The cleaning block 243 has multiple air outlets 2431 at one end facing the cleaning roller 22. One end of the connecting pipe 244 is connected to the cleaning block 243, and the other end is connected to the output end of the air pump 245. Some paper scraps are located on the bristles 232 at the end away from the mounting plate 23. The air discharged from the air outlets 2431 can blow off the paper scraps on the bristles 232 at the end away from the mounting plate 23. Specifically, the cleaning block 243 has multiple air inlets at the end away from the air outlets 2431, and the air inlets communicate with the air outlets 2431. The end of the connecting pipe 244 away from the air pump 245 is connected to the air inlets. Specifically, the cleaning block 243, the connecting pipe 244, and the air pump 245 are used for deep cleaning of the bristles 232 after the work is completed.

[0043] Specifically, the air outlet 2431 is parallel to the guide surface 2411. When the pressure rod 242 comes into contact with the bristles 232, the gas discharged from the air outlet 2431 can clean the paper scraps and residues on the bristles 232.
