[0002] In packaging printing, paper printing, and other fields, gravure printing presses are widely used due to their advantages such as high printing precision and good color reproduction. The doctor blade assembly is one of the core components of a gravure printing press, and its main function is to scrape off excess ink from the printing plate surface to ensure clear printing patterns and uniform colors.

[0003] Traditional gravure printing presses typically use a multi-bolt fixing structure to secure the doctor blade and other components to their corresponding mounting positions on the printing press. In actual production, due to changes in printing materials and ink types, the doctor blade needs to be replaced or cleaned periodically; additionally, wear and tear on the doctor blade after prolonged use necessitates timely disassembly and maintenance.

[0004] However, traditional bolt-fixed structures have the following drawbacks: they require special tools such as wrenches for disassembly and assembly, and operators need to tighten multiple sets of bolts one by one. This not only makes the operation cumbersome, but also makes it difficult to operate due to the hidden location of the bolts or the narrow space. This seriously affects the downtime maintenance efficiency of the printing press and indirectly reduces production capacity. Utility Model Content

[0029] In one embodiment of this utility model, such as Figures 1-6As shown, a unit-type gravure printing machine is provided, including a frame 1. A printing worktable 2 is provided on the top of the frame 1. A tilting motor 3 is installed on one side of the bottom of the frame 1. A movable frame 4 is rotatably connected to the inner side of the frame 1. The movable frame 4 is rotatably connected to the frame 1. A tilting mechanism is provided on the movable frame 4. The movable frame 4 is rotatably mounted on the frame 1 through the tilting mechanism. The tilting mechanism includes a tilting motor 3 and a tilting rod 30. The tilting motor 3 is fixed to the bottom of the frame 1. The tilting rod 30 is connected to the tilting motor 3 and the movable frame 1 through the tilting mechanism. The movable frame 4 is fixedly connected. The yaw motor 3 drives the yaw rod 30 to move linearly, which in turn drives the movable frame 4 to move. Since the movable frame 4 is rotatably connected to the frame 1, the movable frame 4 will rotate on the frame 1, thereby adjusting the angle between the doctor blade assembly and the printing plate. A drive motor 5 is installed inside the top of the movable frame 4. Two transmission screws 6 rotate inside the movable frame 4. One end of the two transmission screws 6 is connected to the output end of the drive motor 5. The surfaces of the two transmission screws 6 are threaded with connecting seats 7. A connecting plate 8 is fixed to the bottom of the connecting seat 7. The internal structure of the connecting plate 8 contains a doctor blade assembly, which includes a doctor blade 9, a positioning block 10, and a fixing seat 11. The doctor blade 9 and the fixing seat 11 are fixed together by rivets. The fixing seat 11 is fixed to both sides of the positioning block 10. A fixing frame 12 is fixed to the top of the positioning block 10. A locking block 13 is fixed to the top of the connecting plate 8. The locking block 13 has a locking mechanism inside for fixing the fixing frame 12 and the locking block 13. By adopting a quick-release design for the doctor blade assembly, no special tools are needed for disassembly and assembly. The doctor blade assembly can be quickly disassembled and assembled simply by operating the locking mechanism, which greatly improves the ease of disassembly and assembly and the efficiency of use, and reduces maintenance costs. In addition, by setting the transmission screw 6, the connecting plate 8, and the connecting seat 7, the doctor blade assembly can move smoothly at the bottom of the movable frame 4, thereby ensuring the uniformity of the doctor blade and the printing quality. At the same time, the movable connection design between the movable frame 4 and the frame 1, as well as the drive of the yaw motor 3 and the drive motor 5, allows the doctor blade assembly to be flexibly adjusted according to different printing needs, further improving the applicability of the equipment and the printing effect.

[0030] Reference Figure 4 - Figure 5As shown, in this embodiment: the locking mechanism includes a handwheel 14 threadedly connected to the side wall of the locking block 13. A push block 15 is fixed to one end of the handwheel 14 inside the locking block 13. Two pressure plates 16 slide inside the locking block 13, located at opposite ends of the push block 15. Two locking rods 17 are fixed to the other side of the pressure plates 16. Locking grooves 18 matching the two locking rods 17 are provided at both ends of the inner side of the fixing bracket 12. Springs 19 are fitted onto the surface of each locking rod 17. One end of the spring 19 is fixed to the inside of the locking block 13, and the other end is fixed to the pressure plate 16. The push block 15 is elliptical in shape. Rotating the handwheel 14 causes the push block 15 to rotate. Due to the elliptical shape of the push block 15, during rotation, the two ends of the push block 15 will... Do not press the two pressure plates 16 to the sides. When the two pressure plates 16 are pressed, they will drive the two locking rods 17 to move to the sides and insert into the locking grooves 18 at both ends of the inner side of the fixing frame 12, thereby locking the fixing frame 12. This achieves quick installation and fixing of the doctor blade assembly, which is convenient to operate and does not require special tools, greatly improving disassembly efficiency. When it is necessary to disassemble the doctor blade assembly, simply turn the handwheel 14 in the opposite direction to drive the push block 15 to rotate in the opposite direction. The two ends of the push block 15 will gradually separate from the two pressure plates 16. At this time, the two springs 19 will push the two pressure plates 16 to move towards the middle. The two pressure plates 16 will drive the two locking rods 17 to move towards the middle until the two locking rods 17 are respectively disengaged from the locking grooves 18 at both ends of the inner side of the fixing frame 12, thereby releasing the locking of the fixing frame 12 and completing the disassembly of the doctor blade assembly.

[0031] Reference Figure 5 As shown in this embodiment: both sides of the locking block 13 are fixed with limit blocks 20, and both ends of the two pressure plates 16 are provided with limit grooves 21 that match the limit blocks 20. Through the cooperation of the limit blocks 20 and the limit grooves 21, the pressure plates 16 are limited to prevent them from shifting or shaking during movement, thus improving the stability and reliability of the locking mechanism. At the same time, the design of the limit blocks 20 and the limit grooves 21 simplifies the structure of the locking mechanism, making it more compact and easier to install and use in small screen printing machines. In actual operation, users can easily disassemble and assemble the squeegee assembly by turning the handwheel 14, which greatly improves the ease of operation and efficiency of the equipment.

[0032] Reference Figure 5 As shown in this embodiment: an anti-slip pad 22 is fitted on the surface of the long shaft end of the handwheel 14. One side of the anti-slip pad 22 abuts against the outer surface of the locking block 13. By setting the anti-slip pad 22, the firmness between the handwheel 14 and the locking block 13 is increased, and loosening is avoided, which would affect the fixing effect.

[0033] Reference Figure 1 and Figure 3 As shown in this embodiment: vertical plates 23 are provided at both ends of the movable frame 4, a clamping plate 24 is fixed at the bottom of the vertical plate 23, and fastening bolts 25 are provided at both ends of the top of the clamping plate 24. A limit frame 26 is provided at the top of the printing worktable 2. With the clamping plate 24, fastening bolts 25 and limit frame 26, when printing is required, the movable frame 4 is rotated to a suitable position by the drive of the yaw motor 3 and the drive motor 5, and the clamping plate 24 is inserted into the outside of the limit frame 26. The clamping bolts 25 are used to fix the clamping plate 24 and the limit frame 26, which can limit the position of the movable frame 4 and prevent the movable frame 4 from moving or shaking during the printing process, thus ensuring the stability and quality of printing.

[0034] Furthermore, a control box 31 is fixed on the side of the frame 1. The control box 31 is electrically connected to the yaw motor 3 and the drive motor 5 respectively, and is used to control the working status of the yaw motor 3 and the drive motor 5.

[0035] Working Principle: The quick-release design of the doctor blade assembly eliminates the need for special tools during assembly and disassembly. Simply operating the locking mechanism allows for rapid assembly and disassembly, significantly improving ease of use and reducing maintenance costs. Furthermore, the transmission screw 6, connecting plate 8, and connecting seat 7 ensure smooth movement of the doctor blade assembly at the bottom of the movable frame 4, guaranteeing uniform ink application and printing quality. Simultaneously, the movable connection between the movable frame 4 and the machine frame 1, along with the oscillation motor 3 and drive motor 5, allows for flexible adjustment of the doctor blade assembly according to different printing needs, further enhancing the equipment's applicability and printing effect. This is achieved by rotating handwheel 1. 4. The push block 15 is rotated. Since the push block 15 is elliptical in shape, during rotation, the two ends of the push block 15 will press the two pressure plates 16 to the sides respectively. After being pressed, the two pressure plates 16 will drive the two locking rods 17 to move to the sides and insert into the locking grooves 18 at both ends of the inner side of the fixing frame 12, thereby locking the fixing frame 12. This achieves quick installation and fixing of the doctor blade assembly, which is convenient to operate and does not require special tools, greatly improving disassembly efficiency. When it is necessary to disassemble the doctor blade assembly, simply turn the handwheel 14 in the opposite direction to drive the push block 15 to rotate in the opposite direction. The two ends of the push block 15 will gradually separate from the two pressure plates 16. At this time, the two springs 19 will push the two pressure plates 16 to the sides respectively. As plate 16 moves towards the center, the two pressure plates 16 drive the two locking rods 17 to move towards the center until the two locking rods 17 disengage from the locking grooves 18 at both ends of the inner side of the fixing frame 12. This releases the locking of the fixing frame 12, thus completing the disassembly of the doctor blade assembly. The cooperation of the limiting block 20 and the limiting groove 21 limits the pressure plate 16, preventing it from shifting or shaking during movement, thus improving the stability and reliability of the locking mechanism. Simultaneously, the design of the limiting block 20 and the limiting groove 21 simplifies the structure of the locking mechanism, making it more compact and easier to install and use in small screen printing machines. In actual operation, the user only needs to turn the handwheel 14. The easy and quick assembly and disassembly of the doctor blade assembly greatly improves the ease of operation and efficiency of the equipment. The anti-slip pad 22 increases the firmness between the handwheel 14 and the locking block 13, preventing loosening and affecting the fixing effect. With the setting of the clamping plate 24, fastening bolts 25 and limiting frame 26, when printing is required, the movable frame 4 is rotated to the appropriate position by the drive of the yaw motor 3 and the drive motor 5, and the clamping plate 24 is inserted into the outside of the limiting frame 26. The fastening bolts 25 are used to fix the clamping plate 24 and the limiting frame 26, which can limit the position of the movable frame 4 and prevent the movable frame 4 from moving or shaking during the printing process, thus ensuring the stability and quality of printing.

[0036] The unit-type gravure printing machine provided in this application allows for quick fixing and disassembly of the squeegee assembly via a locking mechanism, eliminating the need for special tools. Operators only need to turn the handwheel 14 to lock or unlock, shortening assembly and disassembly time, reducing maintenance time, and improving production efficiency.
