Description

Technical Field

[0001] The utility model relates to the technical field of ink scraping devices, in particular to an adjustable ink scraping device for intaglio printing. Background Technique

[0002] Intaglio printing is a direct printing method that directly imprints the ink contained in the intaglio pits onto the printing substrate. The shade levels of the printed image are determined by the size and depth of the pits. If the pits are deeper, more ink is contained, and the ink layer left on the printing substrate after imprinting is thicker; on the contrary, if the pits are shallower, the ink content is less, and the ink layer left on the printing substrate after imprinting is thinner. Currently, when intaglio printing machines on the market are printing, in order to avoid the situation that the surface of the intaglio printing roller is not clean during printing, resulting in printing defective products, a scraper is used to scrape off the excess ink on the surface of the printing roller. However, most ink scraping devices have a single structure. When the ink scraping blade is worn, it will affect the scraping of the ink, thereby affecting the effect of intaglio printing. For this reason, we propose an adjustable ink scraping device for intaglio printing. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an adjustable ink scraping device for intaglio printing. The elasticity of the spring can make the auxiliary scraper automatically fit the surface of the intaglio printing roller, thereby preventing the scraper from being worn and affecting the ink scraping effect. And using bolts for fixation is also convenient for subsequent disassembly and assembly, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an adjustable ink scraping device for intaglio printing, including an ink cartridge and an adjusting frame;

[0005] Ink cartridge: Fixing seats are fixed at both ends of the left side surface. A through groove is opened inside the fixing seat. The lifting rod is slidably connected to the through groove inside the fixing seat. The front and rear ends of the adjusting frame are respectively rotatably connected to the shaft holes on the surfaces of two corresponding lifting rods. A screw rod is threadedly connected to the screw hole on the surface of the adjusting frame. The right end of the screw rod is rotatably connected to the middle of the left side surface of the knife seat. An auxiliary unit is arranged on the top surface of the knife seat, and an adjusting unit is arranged on the outer side surface of the lifting rod;

[0006] Among them: It also includes a scraper, and the scraper is inserted into the inside of the knife seat.

[0007] The lifting rod slides inside the fixing seat to adjust the height of the scraper. At the same time, rotating the screw rod can adjust the distance between the scraper and the intaglio printing roller to meet different ink scraping requirements. The scraper can scrape off the excess ink on the surface of the intaglio printing roller, thus facilitating intaglio printing.

[0008] Furthermore, the auxiliary unit includes an auxiliary tool holder, a sliding rod, a connecting seat, a spring and an auxiliary scraping blade. There are two connecting seats which are respectively fixed on both sides of the top surface of the tool holder. A spring is installed inside the connecting seat. A sliding rod is slidably connected inside the connecting seat. The left end of the sliding rod is fixedly installed with the right end of the spring. The right end of the sliding rod is connected to one side of the left surface of the auxiliary tool holder. An auxiliary scraping blade is inserted into the auxiliary tool holder. When the spring extends, the auxiliary scraping blade fits with the surface of the gravure printing roller, so that when the scraping blade wears, it will not affect the ink scraping effect, thereby improving the ink scraping effect.

[0009] Furthermore, the adjusting unit includes an adjusting wheel, a placement groove, a return spring, a locking rod and a support plate. The adjusting wheel is installed at the end of the adjusting frame. The placement groove is opened on the outer side surface of the lifting rod. A return spring is provided inside the placement groove. The bottom end of the return spring is connected to the top surface of the support plate which slides inside the placement groove. A locking rod corresponding to and mating with the locking hole on the outer side of the adjusting wheel is fixed on the front side of the top surface of the support plate. When the return spring contracts, the locking rod is inserted into the locking hole on the surface of the adjusting wheel, so as to lock after the angle of the scraping blade is adjusted, to prevent the scraping blade from loosening and affecting the ink scraping of the gravure printing roller.

[0010] Furthermore, it further includes an elastic bump and a fixing hole. The elastic bump is fixed at the bottom end of the left side surface of the lifting rod. The fixing holes are evenly opened on the left side surface of the fixing seat. The elastic bump is correspondingly clamped with the fixing hole to facilitate the adjustment and fixing of the height of the lifting rod.

[0011] Furthermore, it further includes a bolt and a main bolt. The bolt passes through the through hole on the top surface of the auxiliary tool holder and is threadedly connected to the screw hole on the top surface of the auxiliary scraping blade. The main bolt passes through the through hole on the top surface of the tool holder and is threadedly connected to the screw hole on the top surface of the scraping blade. Using the bolt and the main bolt facilitates the quick disassembly and assembly of the auxiliary scraping blade and the scraping blade respectively.

[0012] Furthermore, it further includes a limiting rod. There are two limiting rods which are fixedly installed on the left side surface of the tool holder corresponding to the front and back. The limiting rod is slidably connected to the limiting hole on the surface of the adjusting frame. The limiting rod slides inside the limiting hole to increase the stability when the scraping blade is adjusted.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: The adjustable ink scraping device for gravure printing of the present utility model has the following advantages:

[0014] 1. By sliding the lifting rod inside the fixing seat to adjust the height of the scraping blade, and at the same time rotating the screw rod, the distance between the scraping blade and the gravure printing roller can be adjusted to meet different ink scraping requirements. The scraping blade can scrape off the excess ink on the surface of the gravure printing roller, thereby facilitating gravure printing.

[0015] 2. The auxiliary scraper is attached to the surface of the gravure printing roller by spring extension, so that when the scraper wears, it will not affect the ink scraping effect, thus improving the ink scraping effect.

[0016] 3. The locking rod is inserted into the locking hole on the surface of the adjusting wheel by the contraction of the return spring, so as to lock the scraper after adjusting the angle of the scraper, preventing the scraper from loosening and affecting the ink scraping of the gravure printing roller.
