[0002] Electroengraved rollers play a vital role in many modern industrial fields, including printing and packaging. Electroengraved rollers use electronic engraving technology to create precise graphic information on the surface of metal rollers, enabling high-quality printing or pattern transfer processes. As requirements for product appearance quality and printing accuracy continue to rise across various industries, the use of electroengraved rollers is becoming increasingly widespread, leading to a corresponding increase in production scale and shipping frequency.

[0003] Currently, the common practice for transporting electroengraving rollers is to use simple wooden or plastic brackets to secure them, then wrap the rollers with a layer of plastic film or bubble wrap for protection, and finally place them in cardboard or wooden boxes for transportation. However, this traditional packaging and transport method has the following drawbacks:

[0004] The engravings on the surface of the electric engraving roller are extremely fine. During transportation, even if it is wrapped in a film or bubble film, once it is hit or bumped by external force, it may still cause friction and collision between the surface of the roller and the bracket or the inner wall of the packaging, thereby damaging the engravings and affecting the printing quality and service life of the roller.

[0005] In view of this, we propose a protective device for an electric engraving roller to solve the existing problem. Utility Model Content

Figure 6 , the electric engraving roller is fixedly connected to the roller shaft. When in use, the roller shaft is placed inside the support groove 6, and under the action of gravity, the support frame 4 is compressed in the direction close to the fixed shell 3 to support the spring 5;

[0031] Both sides of the support frame 4 are rotatably connected to a pressing plate 7, the upper end of the pressing plate 7 is fixedly connected to an arc-shaped pressing block 8, and both ends of the fixed shell 3 are fixedly connected to a driving shaft 9 that fits with the lower end of the pressing plate 7. A torsion spring is installed between the pressing plate 7 and the support frame 4, and under the action of the torsion spring, the pressing block 8 is pushed to swing away from the two ends of the electric engraving roller;

[0032] When in use, the roller is placed inside the support groove 6. Under the action of gravity, the support frame 4 is pressed toward the fixed housing 3 to compress the support spring 5. The lower end of the pressing plate 7 first contacts the driving shaft 9. The support frame 4 continues to slide toward the fixed housing 3. The driving shaft 9 pushes the pressing plate 7 to swing, thereby causing the pressing block 8 to swing toward the two ends of the electric engraving roller until the pressing block 8 and the two ends of the electric engraving roller are in contact. The pressing block 8 fixes the electric engraving roller to the current position.

[0033] A dust cover 10 is hinged at one end of the carrying shell 1. When in use, the dust cover 10 is rotated to cover the carrying shell 1 to protect the electric engraving roller.

[0034] The open end of the bearing shell 1 is fixedly connected to an extended dust ring 11, Figure 4 A sealing rubber ring 12 is installed on the extended dust ring 11. When in use, the dust cover 10 is rotated to fit the dust cover 10 and the bearing shell 1, and the sealing rubber ring 12 improves the sealing effect.

[0035] There are two compression shells 13 fixedly connected inside the dust cover 10, and a fixed compression frame 14 is slidably connected inside the compression shell 13. A compression spring 15 is installed between the fixed compression frame 14 and the compression shell 13. In the initial state, the compression spring 15 pushes the fixed compression frame 14 in the direction away from the compression shell 13. A U-shaped compression groove 16 is provided at one end of the fixed compression frame 14 away from the compression shell 13. When in use, the dust cover 10 is rotated so that the dust cover 10 and the bearing shell 1 are fitted together, and the compression groove 16 presses the roller shaft inside the electric engraving roller downward, thereby further improving the fixing effect of the electric engraving roller.

[0036] The support groove 6 and the pressing groove 16 are both rotatably connected to the roller 17. The roller shaft inside the electric engraving roller fits with the roller 17, making it easy to adjust the fixed position of the pressing plate 7 according to the length of the electric engraving roller; an arc-shaped groove is opened in the middle of the roller 17 to facilitate the fit of the roller shaft of the electric engraving roller and the roller 17. Example

[0037] Two limit plates 18 are fixedly connected inside the carrying shell 1, and the carrying plate 2 is slidably connected between the two limit plates 18. A plurality of U-shaped limit grooves 19 are provided on the two limit plates 18, and a plurality of limit shafts 20 that cooperate with the limit grooves 19 are fixedly connected on both sides of the carrying plate 2. When in use, the limit shafts 20 are placed inside the limit grooves 19, so that the carrying plate 2 slides up and down between the two limit plates 18; two pulling plates 21 are slidably connected inside the carrying shell 1, and the two pulling plates 21 are respectively located on both sides of the carrying plate 2.

The inclined surface of the support block 22 contacts the limit shaft 20, and the pulling plate 21 continues to slide, thereby driving the limit shaft 20 to slide toward the higher end of the support block 22, thereby pushing the carrying plate 2 upward to the limit position, so that the electric engraving plate is easy to be taken out from the inside of the carrying shell 1;

[0039] After use, the dust cover 10 is rotated toward the direction close to the carrying shell 1, and the pulling plate 21 is pulled to slide synchronously through the connecting rod 23. At this time, under the action of gravity, the limit shaft 20 is always in contact with the inclined surface of the support block 22. Then, the limit shaft 20 slides downward to the extreme position, and the carrying plate 2 slides downward to the extreme position, and the electric engraving roller is stored in the inside of the carrying shell 1.
