The cleaning component 2 is designed to maintain cleanliness during the printing process. The ratchet 21 is designed to provide a stable limiting effect, and secondly, the pawl 22 is used to achieve the limiting effect of the ratchet 21. Secondly, the winch drum 23 on the ratchet 21 is designed to realize the rotation of the ratchet 21 to bring it to the winch drum 23, and then the force is transmitted to the connecting column 25 through the connecting line 24. At this time, the connecting column 25 can achieve stable up and down movement under the pull of the connecting line 24, and then the design of the connecting shaft 27 makes the connecting column 25 move when moving. Finally, the handle 26 on the outer side of the winch drum 23 is designed to facilitate the user to rotate the entire cleaning component 2.

[0032] Furthermore, if Figure 1 As shown: a printing plate roller 4 is installed on the adjacent side of the two printing base frames 1, and a transfer roller 5 is installed on the adjacent side of the two printing base frames 1. The transfer roller 5 is used to transfer printing materials or packaging bags, and the printing plate roller 4 is used to print the packaging bags.

[0033] In order to solve the problem that the cleaning cotton is inconvenient to remove after long-term use, such as Figure 1 , Figure 3 and Figure 4 As shown: the outer side of the cleaning component 2 is fixedly connected with a disassembly component 3, the disassembly component 3 includes a positioning column 31, the inner wall of the positioning column 31 is fixedly connected to the connecting shaft 27, the outer side of the connecting shaft 27 is sleeved with a spring 32, the outer side of the connecting shaft 27 is slidably connected with a sliding column 33, one end of the spring 32 is fixedly connected to the positioning column 31, and the other end of the spring 32 is fixedly connected to the sliding column 33, and the outer side of the connecting shaft 27 is sleeved with a cleaning cotton 34, one of the inner walls of the connecting shaft 27 is provided with a card slot 35, and the end of the other connecting shaft 27 close to the card slot 35 is fixedly connected with a card block 36, and the outer side of the card block 36 is slidably connected to the card slot 35, and the outer side of the cleaning component 2 is fixedly connected with the disassembly component 3.

[0034] Working principle:

[0035] like Figure 1 - Figure 4 As shown:

[0036] When in use: first, the transfer roller 5 transfers the packaging bag to be printed to the printing plate roller 4. When the packaging bag passes through the printing plate roller 4 and the transfer roller 5, the printing of the packaging bag can be achieved. Secondly, when the printing plate roller 4 needs to be cleaned, the handle 26 is held and pushed, and then the ratchet 21 is driven to rotate. When the ratchet 21 rotates, the winch drum 23 drives the connecting line 24 to move the connecting column 25 to the top. At the same time, the movement of the connecting column 25 drives the connecting shaft 27 to slide on the slide groove of the printing base 1, which can drive the cleaning cotton 34 to move to the surface of the printing plate roller 4. When the cleaning cotton 34 contacts the printing plate roller 4, the printing plate roller 4 is cleaned by the cleaning cotton 34. The cleaning cotton 34 can be directly removed, and the sliding column 33 is pulled to slide toward the positioning column 31, and the new cleaning cotton 34 is installed. After the installation is completed, the two connecting shafts 27 are overlapped, and the block 36 is engaged in the slot 35. At this time, the sliding column 33 is released, and under the pressure of the spring 32, the cleaning cotton 34 is moved close to each other and fit together to complete the replacement of the cleaning cotton 34.
