Description

Technical Field

[0001] The utility model relates to the technical field of carton printing, in particular to a low-consumables watermark carton printing device. Background Art

[0002] Watermark carton printing typically involves rolling an inking roller over a cartridge filled with water-based ink. This roller then transfers the ink to a substrate, and finally, an embossing roller embosses a specific color pattern onto the substrate. Existing printing technologies often use a doctor blade to scrape excess ink from the inking roller and return it to the cartridge, minimizing ink usage and reducing ink loss.

[0003] During the printing process, since the ink is squeezed by the squeegee, the scraped ink is easily mixed with agglomerated ink particles in the ink cartridge after it is re-collected into the ink cartridge. When these ink particles are transferred to the inking roller for printing on the cardboard, the particles are prone to ink dragging, thereby affecting the printing effect. In view of this, we propose a low-consumption watermark carton printing device. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a low-consumption watermark carton printing device to solve the technical problem that during the printing process, due to the ink being squeezed by the ink scraper, the scraped ink is easily mixed with agglomerated ink particles in the ink cartridge after being re-collected into the ink cartridge, and these ink particles are easily dragged when transferred to the inking roller for printing on the cardboard, thereby affecting the printing effect.

[0024] The auxiliary component 8 includes a support bracket 801, a group of support brackets 801 are fixed to the inner wall of the ink cartridge 6, a magnetic groove 802 is opened on the inner side of the support bracket 801, and a filter box 803 is set on the surface of the support bracket 801, wherein the filter box 803 is engaged with the inside of the ink cartridge 6, and the distance between the support bracket 801 and the adjacent inner wall of the ink cartridge 6 is greater than the width of the filter box 803, and a filter screen 804 is provided at the bottom inside the filter box 803, and a group of clamping plates 805 are fixed to the outer surface of the filter box 803. Furthermore, the clamping plates 805 are made of metal, and the filter box 803 forms a magnetic clamping structure with the magnetic groove 802 through the clamping plates 805. The utility model uses the ink scraper 705 to effectively scrape the excess ink on the surface of the inking roller 5, thereby reducing ink loss. The scraped ink falls into the filter box 803, and the filter screen 804 effectively blocks the ink particles in a condensed state, preventing the ink particles in a condensed state from entering the ink cartridge 6, thereby reducing the phenomenon of particles dragging ink. When it is necessary to process the ink particles on the surface of the filter screen 804, since the filter box 803 is directly moved upward and its part will be blocked by the inking roller 5, a little force is applied to move the card plate 805 to the left out of the magnetic suction groove 802, and then the filter box 803 is moved to the left as a whole, so that the filter box 803 can be easily taken out.

[0025] It is worth noting that the ink scraping assembly 7 includes a support plate 701, a group of support plates 701 are fixed to one side of the top of the ink cartridge 6, and a rotating frame 702 is engaged on the inner side of a group of support plates 701, wherein the support plate 701 and the ink cartridge 6 are integrally formed, and the rotating frame 702 forms a rotating structure with the support plate 701 through a clamping shaft, and the two ends of the rotating frame 702 are fixed with a clamping shaft, and the end of the front clamping shaft away from the rotating frame 702 is connected to the motor 703, and a positioning frame 704 is provided on the outside of the motor 703, and a scraper 705 is engaged inside the rotating frame 702, and the rotating frame 702 and the scraper 705 are connected by bolts 706. Furthermore, the head of the scraper 705 is matched and engaged with the inside of the rotating frame 702, and the scraper 705 forms a detachable structure with the rotating frame 702 through bolts 706. The utility model effectively drives the rotating frame 702 to rotate through the motor 703, thereby facilitating the azimuth adjustment of the scraper 705 inside the rotating frame 702. When the rotating frame 702 is rotated and adjusted to the opening facing upward, the bolt 706 is removed, and the scraper 705 can be easily moved up and removed, making it easy to disassemble and replace the scraper 705.

[0026] Working principle: the cardboard 3 is transported on the conveyor belt surface in the conveyor belt assembly 2, and the pattern on the surface of the cardboard 3 is printed between the embossing roller 4 and the inking roller 5. When the inking roller 5 is working, the excess ink on the surface of the inking roller 5 is scraped by the scraper 705 to reduce ink loss. The scraped ink falls into the filter box 803, and the filter screen 804 blocks the condensed ink particles to prevent the condensed ink particles from entering the ink cartridge 6, thereby reducing the ink drag phenomenon of particles. When the printing is completed, when the ink particles on the surface of the filter screen 804 need to be processed, since the filter box 803 is directly moved up, its part will be blocked by the inking roller 5. Therefore, a little force is used to move the card plate 805 to the left out of the magnetic suction groove 802, and then the filter box 803 is moved to the left as a whole, so that the filter box 803 can be taken out conveniently. The motor 703 drives the rotating frame 702 to rotate. When the rotating frame 702 is rotated and adjusted to the opening upward, the bolt 706 is removed, and the scraper 705 can be easily moved up and pulled out of the rotating frame 702 for disassembly and replacement.
