[0002] At present, most motors use the power output shaft of the motor to transfer kinetic energy to the power demand mechanism. However, in the portable rotary printer technology, it involves the control of the ink cartridge nozzle. Electrical signal transmission is required between the stationary part and the rotating part of the motor. Brushes or slip rings need to be set in the printer for electrical connection. The brushes or slip rings of the rotary printer generally require more than 8-wire slip rings or brushes to meet the communication requirements of each component. The more wires the brush or slip ring has, the higher the height, which limits the size of the rotary printer and the assembly process is more complicated. In addition, the slip rings and brushes are also easily damaged during use, and it is very troublesome to replace them, which has become a technical problem that needs to be solved urgently by technical personnel in this field.

[0026] The printing control component includes a main control circuit board 410 and a drive control board 420 . The ink cartridge component includes an ink cartridge holder 510 and an ink cartridge 520 . The ink cartridge holder 510 is used to fix the ink cartridge 520 .

[0027] The motor is arranged below the top cover 110, and the power output shaft 211 of the motor is fixedly connected to the top cover 110. The main control circuit board 410, the drive control board 520, the ink cartridge holder 510 and the ink cartridge 520 are arranged from top to bottom below the motor. Below the ink cartridge 520 is the bottom cover 130, and the charging port 131 of the power supply is also arranged on the bottom cover 130. In this embodiment, the motor body 210 is directly or indirectly fixedly connected to the main control circuit board 410, the drive control board 520, the ink cartridge holder 510 and the ink cartridge 520, so that the printing control component and the ink cartridge component are driven to rotate by the motor body 210. When the motor is in working condition, since the power output shaft 211 of the motor is fixedly connected to the top cover 110 of the outer shell, the power output shaft 211 of the motor will remain stationary, and the motor body 210 will rotate. At the same time, the motor body 210 drives the printing control component and the ink cartridge component to rotate. A printing nozzle is arranged at the bottom of the ink cartridge 520 in the ink cartridge assembly. During the rotation process, the printer control component controls the nozzle to spray ink, thereby achieving the purpose of rotational printing.

[0028] like Figure 4 As shown, in some preferred embodiments, the rotary stamp printer further comprises a rotating bracket 300. In this embodiment, the rotating bracket 300 is a cylindrical structure. A hollow is provided on the side wall of the rotating bracket 300, which can effectively reduce the weight of the rotating bracket 300. A first protrusion 304 and a second protrusion 305 are also provided on the side wall of the rotating bracket 300. Screw holes are provided on the first protrusion 304 and the second protrusion 305.

The motor bracket 230 and the printing control assembly are fixedly connected to the rotating bracket 300 by screws and the first protrusion 304 and the second protrusion 305. The ink cartridge assembly is fixedly connected to the rotating bracket 300 by screws and screw holes 306. By providing the rotating bracket 300 to connect various mechanisms inside the housing together, the motor body 210 can ensure that the rotating assembly inside the housing rotates more stably during the rotation process.

[0029] like Figure 4 As shown, in some preferred embodiments, an upper limit portion 302 and a lower limit portion 308 are provided on the rotating bracket 300, the outer diameters of the upper limit portion 302 and the lower limit portion 308 are larger than the outer diameter of the bracket body 302, and the outer diameters of the two limit portions are the same, the upper limit portion 302 is provided on the top 303 of the bracket, and the lower limit portion 308 is provided on the bottom 307 of the bracket. During the rotation process, the rotating bracket 300 contacts the outer shell through the upper limit portion 302 and the lower limit portion 308, and the bracket body 301 does not contact the outer shell. The above device can reduce the contact area between the rotating bracket 300 and the outer shell, effectively reduce the friction between the rotating bracket 300 and the outer shell, and reduce the power consumption of the motor.

[0030] like Figure 5 , 6 As shown, in some preferred embodiments, the upper limit portion 302 and the lower limit portion 308 can also be set at the bracket top 304 and the bracket bottom 307, and the distance between the upper limit portion 302 and the lower limit portion 308 is greater than 1 / 2 of the height of the bracket body 301.

[0031] In some preferred embodiments, a limiting ring 140 and a connecting portion 111 are provided between the top cover 110 and the housing side wall 130, the limiting ring 140 is provided on the top of the housing side wall 120 by a first screw 141, the connecting portion 111 is fixedly connected to the limiting ring 140 by a second screw 112, the power output shaft of the motor is fixedly connected to the connecting portion 111, and in this embodiment, a limiting protrusion 142 is further provided on the inner side of the bottom of the housing side wall 120, and the inner diameter of the limiting protrusion 142 is smaller than the outer diameter of the lower limiting portion 308. By providing the limiting ring 140 and the limiting protrusion 142, the rotating bracket 300 can be prevented from shaking up and down during the rotation process.
