Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: a detachable printing assembly for a three-color printing machine, including an operating table 1, a rotating wheel 3 is rotatably connected to one side of the operating table 1, a printing stick 2 is arranged inside the operating table 1, both ends of the printing stick 2 are fixedly connected to connecting tubes 4, one end of the rotating wheel 3 is fixedly connected to a hollow column 5, the connecting tube 4 is slidably connected to the outer wall of the hollow column 5, the other end of the rotating wheel 3 is rotatably connected to a connecting column 6, a handle 7 is fixedly connected to the outer wall of the connecting column 6, a support column 8 is fixedly connected inside the connecting column 6, the support column 8 is rotatably connected to the inside of the rotating wheel 3, a clamping block 9 is fixedly connected to one end of the support column 8, the clamping block 9 is rotatably connected to the inside of the connecting tube 4, and a support assembly is fixedly connected to one side of the operating table 1.

[0025] Specifically, when installing the printing rod 2, first, the connecting tube 4 fixedly connected at both ends of the printing rod 2 is inserted into the outer wall of the hollow column 5 to ensure a tight connection. Then, by twisting the handle 7, force is applied to rotate the handle 7, and this action drives the rotation of the connecting column 6. The rotation of the connecting column 6 causes the movement of the support column 8 inside the rotating wheel 3, so the support column 8 starts to rotate. The rotation of the support column 8 also causes the block 9 fixedly connected at one end to start rotating inside the connecting tube 4. The design shape of the block 9 has been carefully considered, so while rotating, it will be stuck inside the connecting tube 4, firmly fixing the connecting tube 4, realizing the rapid positioning and installation of the printing rod 2, making the entire installation process efficient and convenient.

[0026] Reference Figure 1 and Figure 4 The support assembly includes a support plate 10, one side of the support plate 10 is fixedly connected to one side of the operating table 1, one side of the support plate 10 is fixedly connected to a motor 11, an output end of the motor 11 is fixedly connected to an upper rotating shaft 12, the upper rotating shaft 12 is rotatably connected to the inside of the operating table 1, a synchronous belt 18 is arranged between the upper rotating shaft 12 and the rotating wheel 3, a first cutter disc 13 is fixedly connected to the outer wall of the upper rotating shaft 12, a lower rotating shaft 15 is fixedly connected to the inside of the operating table 1, a slotting knife 14 is arranged on the outer wall of the first cutter disc 13, a second cutter disc 16 is fixedly connected to the outer wall of the lower rotating shaft 15, and an empty slot 17 is arranged inside the second cutter disc 16.

[0027] Specifically, the upper rotating shaft 12 is then driven to start rotating through the output end of the motor 11. The upper rotating shaft 12 passes through the synchronous belt 18 provided on the outer wall, thereby causing the rotating wheel 3 to start rotating synchronously, thereby starting the printing process. At the same time, the upper rotating shaft 12 is also rotated by the first cutter disc 13 fixedly connected to the outer wall. The movement of the first cutter disc 13 transmits force to the slotting knife 14 provided on the outer wall, causing the slotting knife 14 to rotate. The slotting knife 14 cooperates with the empty slot 17 on the outer wall, so that the slotting knife 14 can perform precise slotting operations on the carton. This complex and precise mechanism ensures the smooth progress of the printing process and realizes efficient slotting operations on the carton.

[0028] Reference Figure 1 A cylinder 20 is fixedly connected to one side of the operating table 1, a slider 21 is fixedly connected to the output end of the cylinder 20, a guide rail 19 is fixedly connected inside the operating table 1, the slider 21 is slidably connected to the outer wall of the guide rail 19, and a cleaning brush 22 is arranged on the top of the slider 21.

[0029] Specifically, during the printing process, the cleaning brush 22 disposed at the bottom of the printing roller 2 plays an important role. When the printing roller 2 rotates, the cleaning brush 22 is closely attached to its outer wall, effectively cleaning the dirt and ink residue adhering to the outer wall. At the same time, the slider 21 is driven to move through the output end of the cylinder 20, and it slides on the outer wall of the guide rail 19 under the force. This action enables the cleaning brush 22 disposed on the top to slide at the bottom of the printing roller 2, achieving all-round cleaning of the printing roller 2, and improving the printing quality and efficiency during the printing process.

[0030] Working principle: When installing the printing roller 2, first, insert the connecting tube 4 fixedly connected at both ends of the printing roller 2 into the outer wall of the hollow column 5, then twist the handle 7, the handle 7 is driven by the force to drive the connecting column 6 fixedly connected at one end to rotate, the connecting column 6 is driven by the force to drive the supporting column 8 fixedly connected at one end to rotate inside the rotating wheel 3, the supporting column 8 is driven by the force to drive the clamping block 9 fixedly connected at one end to rotate inside the connecting tube 4, due to the shape design of the clamping block 9, the clamping block 9 will be stuck in the connecting tube 4 to fix it while being rotated, so that the printing roller 2 can be quickly positioned and installed, and then the upper rotating shaft 12 is driven to rotate by the output end of the motor 11, and the upper rotating shaft 12 is driven by the synchronous belt 18 set on the outer wall to rotate. The rotating wheel 3 is driven to rotate synchronously to print. At the same time, the upper rotating shaft 12 also drives the first knife disc 13 fixedly connected to the outer wall to rotate. The first knife disc 13 is forced to drive the slotting knife 14 set on the outer wall to rotate. Through the cooperation between the slotting knife 14 and the empty slot 17, the slotting knife 14 slots the carton. During the printing process, the cleaning brush 22 set at the bottom of the printing roller 2 can clean its outer wall when the printing roller 2 rotates. At the same time, the slider 21 can be driven to move through the output end of the cylinder 20. The slider 21 is forced to slide on the outer wall of the guide rail 19. At this time, the slider 21 drives the cleaning brush 22 set on the top to slide on the bottom of the printing roller 2, thereby cleaning the printing roller 2 in all directions.
