[0022] Please see Figure 1-6This utility model provides a technical solution: a quick-assembly and disassembly fixing structure for a printing plate roller, including a printing plate roller 1, an mounting sleeve 2, a mounting shaft 3, a positioning buckle groove 4, a positioning buckle block 5, a splicing slot 6, a fixing bolt 7, a mounting shaft groove 8, a movable locking block 9, a toggle block 10, a toggle groove 11, a connecting spring 12, a telescopic groove 13, a disassembly groove 14, a stop block 15, a stain-removing liquid nozzle 16, a water nozzle 17, a disassembly block 18, a water guide pipe 19, a stain-removing liquid conduit 20, and a fixing block 21. The mounting sleeve 2 is fitted onto the outer wall of the printing plate roller 1, and the mounting shaft 3 is rotatably mounted at both ends of the printing plate roller 1. The printing plate roller 1 is locked in place by the movable locking block 9 and the mounting shaft groove 8 through a push-locking engagement. The movable locking block 9 has a trapezoidal structure, which allows the printing plate roller 1 to... The mounting sleeve 2 is designed for quick and easy installation, fitting snugly around the printing roller 1. Its metal frame structure allows for effective protection by enclosing the printing roller 1. The lower ends of both sides of the inner wall of the mounting sleeve 2 have splicing slots 6, with positioning buckles 5 protruding from the upper front and rear sides of the inner wall of the splicing slots 6. Fixing blocks 21 are inserted into the inner wall of the splicing slots 6, with positioning grooves 4 on the upper front and rear sides of the fixing blocks 21. The fixing blocks 21 are connected to the splicing slots 6 via the positioning grooves 4 and positioning buckles 5, and are further secured to the splicing slots 6 with fixing bolts 7. This design allows for quick and easy disassembly and assembly of the locking structure, making it suitable for various applications. The installation effect is excellent. The positioning buckle 5 is inserted into the positioning buckle groove 4. The mounting sleeve 2 and the fixing block 21 are inserted through the sides with fixing bolts 7. The fixing block 21 has a mounting shaft groove 8 on its inner side. The mounting shaft 3 is inserted into the mounting shaft groove 8. The lower end of the inner wall of the mounting shaft groove 8 has a telescopic groove 13. The inner wall of the telescopic groove 13 is fixedly connected to the connecting spring 12. One end of the connecting spring 12 is fixedly connected to the movable locking block 9. The movable locking block 9 is elastically telescopically connected to the telescopic groove 13 through the connecting spring 12. The movable locking block 9 is also positioned and moved by the telescopic groove 13 through the toggle block 10 and the toggle groove 11. This makes it easy to move and extend the movable locking block 9, which is convenient for quick disassembly and easy to use. The lower end of the movable locking block 9 is fixedly connected to the toggle block 10. A sliding groove 11 is provided at the lower end of the inner wall of the shrinkage groove 13. The sliding block 10 is slidably inserted into the expansion groove 13. A disassembly groove 14 is provided at the lower rear side of the mounting sleeve 2. The front edges of the upper and lower ends of the inner wall of the disassembly groove 14 are fixedly connected to the abutment block 15. A disassembly block 18 is inserted into the inner wall of the disassembly groove 14. A stain-reducing liquid nozzle 16 and a water spray head 17 are connected and installed on the front side of the disassembly block 18. The stain-reducing liquid nozzle 16 and the water spray head 17 are distributed in a parallel position to the disassembly block 18 and are distributed in a perpendicular position to the printing plate roller 1. The stain-reducing liquid nozzle 16 and the water spray head 17 are positioned and inserted into the mounting sleeve 2 through the disassembly groove 14 and the disassembly block 18. The length of the stain-reducing liquid nozzle 16 and the water spray head 17 matches the length of the printing plate roller 1.This design allows for efficient spraying of the stain remover nozzles 16 and 17, and facilitates easy assembly and disassembly for maintenance and cleaning. The rear side of the disassembly / assembly block 18 is connected to a water guide pipe 19 and a stain remover conduit 20.
[0023] Working principle: When using this quick-release printing roller fixing structure, first remove the printing roller 1 of the device, then push it upwards. The movable locking block 9 retracts elastically through the connecting spring 12, thereby locking and installing it with the mounting shaft groove 8. Then it can be used for printing. When it needs to be disassembled and replaced, the movable locking block 9 can be moved to one side by the lever 10 to quickly release the lock and disassemble it quickly. The disassembly and assembly are manual to avoid failure of the electric mechanism, which may prevent disassembly and assembly. When it is necessary to adapt to different printing rollers 1, it can be disassembled and assembled as a whole through the positioning buckle groove 4, positioning buckle 5 and splicing slot 6. When it is necessary to clean the printing roller 1, the stain-reducing liquid can be sprayed onto the printing roller 1 through the stain-reducing liquid spray nozzle 16. The printing roller 1 can be rotated for full spraying. Then it can be rinsed with water spray head 17. This is the usage process of this quick-release printing roller fixing structure.
