[0021] A plurality of printing wheel assemblies are installed on the top of the frame 1, and the printing wheel assemblies include an L-shaped plate 201 connected to the top of the frame 1 through a sliding assembly, a bearing seat 202 is installed on the L-shaped plate 201, a rotating shaft 203 is connected to the bearing seat 202, a turntable 204 is connected to the other end of the rotating shaft 203, a printing wheel 205 is connected to the end face of the turntable 204 away from the rotating shaft 203, an ink scraper 207 is also installed on the L-shaped plate 201 through an ink hanging plate shaft 206, one end of the ink scraper 207 is pressed on the printing wheel 205, an ink box 208 is provided below the printing wheel 205, and the ink box 208 is connected to the L-shaped plate 201. The printing wheel 205 is dipped with ink from the ink box 208 while rotating, so that the outer wall of the printing wheel 205 is filled with ink, and then the excess ink on the printing wheel 205 is scraped off by the scraper 207 and falls into the ink box 208.

[0022] The sliding assembly includes a linear guide rail 5 connected to the top surface of the frame 1 and a slider 6 connected to the bottom surface of the L-shaped plate 201. The slider 6 is slidably connected to the linear guide rail 5. The bottom of the L-shaped plate 201 is also threadedly connected to a first screw rod 7. One end of the first screw rod 7 is connected to a first hand wheel 8. The position of the L-shaped plate 201 is adjusted by rotating the first hand wheel 8.

[0023] Each of the printing wheel assemblies is independent and does not affect each other, so the printing wheel 205 on each printing wheel assembly can be removed separately. When disassembling, it is only necessary to remove the printing wheel 205 from the turntable 204, which is convenient and quick.

[0024] A transfer assembly is provided at the front end of the printing wheel 205, and the transfer assembly includes a mounting frame 301 installed on the frame 1, and transfer wheels 303 equal in number to the printing wheel 205 are installed on the mounting frame 301 through a transfer shaft 302.
