Description

Technical Field

[0001] This utility model relates to the technical field of roller printing devices, specifically a gravure ink uniform roller printing device. Background Technology

[0002] As is well known, gravure ink, also called gravure liquid ink, is a stable, colored colloidal dispersion system. A roller printing device is used to evenly apply ink to the product to be printed. Typically, the roller printing device is mounted on a printer. Ink is applied to the roller printing device, and then the device prints the ink onto the surface of the product, thus achieving the purpose of roller printing.

[0003] A search revealed a Chinese patent (publication number: CN220808902U) that discloses a gravure ink uniform roller printing device. This device utilizes the cooperation of a stabilizing rod, a pressure plate, and a threaded rod. When the threaded rod is rotated, the threaded connection between the threaded rod and the mounting plate causes the threaded rod to move on the mounting plate, which in turn moves the pressure plate, pressing it against the inner wall of the device. This allows the scraper of the device to be positioned and installed on the printer. The device consists of two corresponding mounting plates that fix the printing cylinder, which are connected to a connecting frame via bolts. However, the device requires complete disassembly and assembly of the printing cylinder, making operation inconvenient. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model discloses a gravure ink uniform roller printing device, comprising a fixed frame 1, which consists of a connecting plate 2 and two fixed plates 3. The two fixed plates 3 are respectively fixedly connected to both ends of the connecting plate 2. One end of the fixed plate 3 is provided with a slot, and a connecting component 16 is installed on the slot. The connecting component 16 includes an insert plate 14 and an insert block 15. The insert block 15 is fixedly connected to one end of the insert plate 14, and the insert plate 14 has a mounting hole near the other end. A roller printing cylinder 21 is installed between the two mounting holes. The roller printing cylinder 21 consists of a cylinder body and a central rod. The central rod is fixedly connected to the cylinder body and passes through the two mounting holes. The length of the cylinder body is equal to the distance between the two insert plates 14. The fixed plate 3 is fixedly fixed with... A threaded tube 17 connected to a slot is fixedly connected to the external threaded tube 17. A slot corresponding to the threaded tube 17 is opened on the external threaded tube 17. A limiting component 20 is threadedly connected to the external threaded tube 17. The limiting component 20 includes a threaded cap 18, which is threadedly connected to the external threaded tube 17. An insert rod 19 is fixedly connected to the inner top wall of the threaded cap 18. As the threaded cap 18 rotates on the external threaded tube 17, the insert rod 19 enters the slot of the insert block 15, fixing the insert block 15 and the fixing plate 3. When it is necessary to remove the printing cylinder 21 from the device, the insert plate 14 can be removed from the fixing plate 3 by rotating the threaded cap 18 on the external threaded tube 17 and removing it. Then, the printing cylinder 21 can be removed from the insert plate 14.

[0023] A cleaning component 4 is installed in the middle of the connecting plate 2. The cleaning component 4 includes an electric telescopic rod, which is located on one side of the middle of the connecting plate 2. A scraper is connected to the telescopic end of the electric telescopic rod. A pressure sensor is installed on the scraper. Multiple slide rods that are slidably connected to the connecting plate 2 are connected to the scraper. By activating the electric telescopic rod, the electric telescopic rod drives the scraper to move, thereby making the pressure sensor at the center of the scraper contact the printing cylinder 21. This allows the scraper to maintain optimal force to scrape the ink off the surface of the printing cylinder 21, thus preventing the scraper from wearing out after prolonged contact with the printing cylinder 21 and failing to completely remove the ink from its surface.

[0024] An adjustment assembly 10 is rotatably connected to the connecting plate 2. The adjustment assembly 10 includes a rotating rod 6, a rotating handle 7 installed in the middle of the rotating rod 6, a rotating block 8 connected to the rotating rod 6, and threaded rods 9 fixedly connected to both ends. The threads of the two threaded rods 9 are in opposite directions.

[0025] A groove 5 is provided in the middle of the connecting plate 2, and the rotating handle 7 is placed in the groove 5. Both ends of the connecting plate 2 are provided with sliding grooves, and a fixing component 22 is slidably connected in the sliding grooves. The fixing component 22 includes an internal threaded cylinder 12, which is threadedly connected to the threaded rod 9. One end of the internal threaded cylinder 12 is fixedly connected to a connecting plate 11, and a clamping plate 13 is connected to the connecting plate 11. The outer wall of the internal threaded tube is multifaceted. By rotating the rotating handle 7, the threaded rod 9 drives the internal threaded cylinder 12 to slide in the sliding groove, and the two clamping plates 13 move to both sides, so that the clamping plates 13 open to both sides, and then the clamping plates 13 abut against the inner wall of the printing equipment, thereby installing the equipment on the printing equipment. Then, when the printing cylinder 21 rotates, the ink on the surface of the printing cylinder 21 can be quickly cleaned.

[0026] In summary, when the printing cylinder 21 needs to be removed from the gravure ink uniform roller printing device, the threaded cap 18 is rotated to disengage it from the external threaded tube 17, and the insert rod 19 is inserted. Then, the insert plate 14 is removed from the fixing plate 3, and the printing cylinder 21 is disassembled from the insert plate 14, thus avoiding the need to disassemble the entire device and making the removal of the printing cylinder 21 convenient.

[0027] When the device needs to be removed from the printing equipment as a whole, the threaded rod 9 is rotated in the inner threaded cylinder 12 by turning the handle 7. Then the inner threaded cylinder 12 slides into the groove inside the connecting plate 2, so that the clamping plate 13 is disengaged from the printing equipment, thus facilitating removal.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
