[0001] This utility model relates to the field of printing roller technology, specifically to an assembled electro-engraving printing roller. Background Technology
[0002] Electro-engraved printing rollers are high-precision rollers manufactured using advanced electronic engraving technology, widely used in gravure printing processes in packaging printing, decorative materials, and specialty paper industries. Their core principle involves using digital control and high-energy electron beams or diamond engraving needles to precisely engrave micro-grooves on the surface of a copper-plated roller, forming image areas, thereby achieving precise ink transfer and high-fidelity reproduction of the pattern.
[0003] After prolonged use, the surface of the engraved printing roller will wear down and need to be replaced. Existing engraved printing rollers are usually one-piece structures, and the old rollers and shafts are typically scrapped, leading to resource waste. Furthermore, existing engraved printing rollers are usually connected to the machine body, requiring the entire roller to be replaced each time a different printing pattern is changed. This is especially problematic for small-batch, multi-variety printing, which necessitates frequent roller replacements and involves installing rollers of different diameters and lengths, making replacement cumbersome and reducing work efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] like Figure 1-5As shown, this utility model discloses an assembled electro-engraving roller, including a rotating shaft 1. A roller sleeve assembly is provided on the rotating shaft 1. The roller sleeve assembly includes roller sleeves A2 and B3 located on the upper and lower sides of the rotating shaft 1, respectively. Roller sleeves A2 and B3 are both connected to the rotating shaft 1 via an installation assembly. The installation assembly includes an installation plate 4 fixedly disposed on the upper and lower sides of the rotating shaft 1, an installation disc 5 slidably disposed on the rotating shaft 1 and located on the left and right sides of the installation plate 4, an insert plate 6, a spring 7, a locking ring A8, and a locking ring B9. A convex ring A10 and a convex ring B11 are fixedly disposed on the outer side of the installation disc 5. The diameter of convex ring A10 is larger than the diameter of convex ring B11. A slot A12 is provided on the side wall of the installation plate 4 away from the rotating shaft 1. The spring 7 is located inside the slot A12. The insert plate 6 is inserted into the slot A12 and slidably connected to the mounting plate 4. The two ends of the spring 7 are fixedly connected to the rotating shaft 1 and the insert plate 6, respectively. The roller sleeves A2 and B3 are each provided with a slot B13 on the side wall facing the rotating shaft 1. The roller sleeves A2 and B3 are sleeved on the mounting plate 5 and abut against each other. The convex ring B11 is located on the left and right sides of the roller sleeves A2 and B3. The convex ring A10 is located on the side of the convex ring B11 away from the roller sleeves A2 and B3. The insert plate 6 is inserted into the slot B13 and abuts against the roller sleeves A2 and B3. The locking rings A8 and B9 are respectively sleeved on the roller sleeves A2 and B3 and are fixedly connected to each other by bolts.In use, roller sleeves A2 and B3 are placed on the upper and lower sides of the rotating shaft 1, respectively. The insert plate 6 is inserted into the slot B13 to abut against roller sleeves A2 and B3, aligning them with the rotating shaft 1. Roller sleeves A2 and B3 are pressed down, causing the insert plate 6 to compress the spring 7 and retract into the slot A12, allowing roller sleeves A2 and B3 to be fitted onto the mounting plate 5. Locking rings A8 and B9 are then fitted onto roller sleeves A2 and B3, respectively, and bolts are used to secure them together, ensuring roller sleeves A2 and B3 are firmly held onto the mounting plate 5. This completes the installation of roller sleeves A2 and B3. When roller sleeve A2... When the surface indentation of roller sleeve B3 shows wear and needs replacement, remove locking rings A8 and B9 from roller sleeves A2 and B3, then separate roller sleeves A2 and B3 from mounting plate 5 and insert plate 6. This completes the disassembly of roller sleeves A2 and B3. Then, install new roller sleeves A2 and B3 onto mounting plate 5 using locking rings A8 and B9. This completes the replacement of roller sleeves A2 and B3 without replacing the rotating shaft 1 or other components, facilitating the replacement of roller sleeves A2 and B3 and avoiding resource waste. When it is necessary to install roller sleeves A2 and B3 of different diameters, the original roller sleeves A2 and B3 are... 3. Remove the large-sized roller sleeves A2 and B3 and place them onto the convex ring A10 or B11. Spring 7 will push the insert plate 6 to adapt to the inner diameter of roller sleeves A2 and B3, allowing them to insert into the slot B13 and connect with roller sleeves A2 and B3. Then, use locking rings A8 and B9 to install roller sleeves A2 and B3 onto the mounting plate 5, which facilitates the installation of roller sleeves A2 and B3 of different diameters. When roller sleeves A2 and B3 of different lengths need to be installed, push the mounting plate 5 to slide it on the rotating shaft 1, so that the length of the mounting plate 5 matches that of roller sleeves A2 and B3. Then, install roller sleeves A2 and B3. Mounted on mounting plate 5, it facilitates the installation of roller sleeves A2 and B3 of different diameters. In summary, this invention has the beneficial effects of avoiding resource waste and facilitating the installation of roller sleeves A2 and B3 of different diameters and lengths. It solves the problem that existing electro-engraving rollers are usually one-piece structures, and the old rollers and rotating shafts 1 are usually scrapped after replacement, resulting in resource waste. Existing electro-engraving rollers are usually connected to the machine body, and each time a printing pattern is changed, the entire electro-engraving roller needs to be replaced. This involves the installation of electro-engraving rollers of different diameters and lengths, which makes replacement cumbersome and reduces work efficiency.
[0021] Preferably, the mounting plate 5 has sliding holes 14 extending through its left and right sides. The rotating shaft 1 is inserted into the sliding holes 14 and slidably connected to the mounting plate 5. A slide bar 15 is fixedly installed on the inner side wall of the sliding holes 14. The rotating shaft 1 has a sliding groove 16, and the slide bar 15 is inserted into the sliding groove 16 and slidably connected to the rotating shaft 1. Because the slide bar 15 is inserted into the sliding groove 16 and slidably connected to the rotating shaft 1, it facilitates the sliding of the mounting plate 5 on the rotating shaft 1. The sliding groove 16 does not extend through the left and right side walls of the rotating shaft 1, thus preventing the mounting plate 5 from sliding off the rotating shaft 1.
[0022] Preferably, the outer walls of the mounting plate 5, the convex ring A10, and the convex ring B11 are all provided with annular grooves 17, and the inner sides of the roller sleeves A2 and B3 are all fixedly provided with inner rings 18. When the roller sleeves A2 and B3 are fitted onto the mounting plate 5, the inner rings 18 are inserted into the annular grooves 17 on the mounting plate 5 and abut against the mounting plate 5. Since the inner rings 18 are inserted into the annular grooves 17 on the mounting plate 5 and abut against the mounting plate 5 when the roller sleeves A2 and B3 are fitted onto the mounting plate 5, the inner rings 18 will hook onto the side wall of the annular grooves 17, which plays a role in restricting the sliding of the mounting plate 5. The roller sleeves A2 and B3 are restricted from sliding by the insert plate 6. Since the outer walls of the convex rings A10 and B11 are all provided with annular grooves 17, it facilitates the connection between the inner rings 18 and the convex rings A10 and B11.
[0023] Preferably, a plurality of magnets 19 are fixedly disposed above the roller sleeve B3, and a plurality of magnetic grooves 20 are formed on the bottom wall of the roller sleeve A2. An iron sheet is fixedly disposed on the top wall of each magnetic groove 20. After the magnets 19 are inserted into the magnetic grooves 20, they are magnetically attracted to the iron sheet on the top wall of the magnetic grooves 20. Because the magnetic attraction force of the magnets 19 is greater than the elastic force of the spring 7 after being inserted into the magnetic grooves 20, it serves to pre-fix the roller sleeve A2 and roller sleeve B3, facilitating the subsequent installation of the locking rings A8 and B9.
[0024] Preferably, guide bars 21 are fixedly provided on the left and right side walls of the slot A12, and guide grooves 22 are provided on the left and right side walls of the insertion plate 6. The guide bars 21 are inserted into the guide grooves 22 and slidably connected to the insertion plate 6. Since the guide bars 21 are inserted into the guide grooves 22 and slidably connected to the insertion plate 6, they serve to guide the insertion plate 6 when it slides.
[0025] Preferably, both roller sleeve A2 and roller sleeve B3 are provided with positioning holes 23, and positioning posts 24 are fixedly provided on the inner sides of both locking rings A8 and B9. When locking rings A8 and B9 are respectively sleeved on roller sleeves A2 and B3, the positioning posts 24 are inserted into the positioning holes 23 and make contact with roller sleeves A2 and B3. Since the positioning posts 24 are inserted into the positioning holes 23 and make contact with roller sleeves A2 and B3, they facilitate the positioning and installation of locking rings A8 and B9.
[0026] Preferably, the mounting plate 5 has a plurality of heat dissipation holes 25 extending through its left and right sides. The presence of these heat dissipation holes 25 facilitates heat dissipation.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
