Preferably, the transmission belt assembly includes a pressing driving pulley 512, a pressing transmission belt 513, and a pressing driven pulley 514.

[0061] See also Figure 4 and Figure 5 The clamping mechanism of this embodiment includes an upper clamping belt 516 , an upper driven pulley 517 , a lower clamping belt 520 and a lower driven pulley 521 .

[0062] An upper driving pulley 515 is provided at the front end of the upper transmission shaft 508, and a lower driving pulley 519 is provided at the front end of the lower transmission shaft 509. A driven pulley 517 and a lower driven pulley 521 are rotatably provided on the inner wall of the front side of the housing 1. The upper driving pulley 515 and the upper driven pulley 517 are connected to each other through an upper clamping belt 516, and the lower driving pulley 519 and the lower driven pulley 521 are connected to each other through a lower clamping belt 520.

[0064] During operation, the portion to be printed on the sterile bag 7 is opened from the right side of the second opening 9 (see Figure 1 ), enters the printing channel between the upper clamping belt 516 and the lower clamping belt 52 (see Figure 3 ), multiple compression springs 525 drive the pressing member 524 to press down the upper clamping belt 516, thereby the upper clamping belt 516 and the lower clamping belt 520 clamp the sterile bag 7. The motor 501 drives the transmission mechanism 503 through the reducer 502, and the transmission mechanism 503 drives the upper clamping belt 516 and the lower clamping belt 520 to rotate, thereby moving the sterile bag 7 along the length direction of the second opening 9, that is, the sterile bag 7 moves from right to left, passing through the heating mechanism 504, the pressing mechanism 505 and the double printing mechanism 506 (see Figure 8), and finally the sterile bag 7 is discharged from the left side of the second opening 9, completing the printing operation.

The lower pressing roller and the upper pressing roller are arranged tangentially, and the upper pressing roller can float and adjust the pressure. When the thickness of the sterile bag 7 is small, the upper pressing roller moves downward, so that the channel between the lower pressing roller and the upper pressing roller for the sterile bag 7 to pass through becomes narrower; when the thickness of the sterile bag 7 is large, the upper pressing roller moves upward, so that the channel between the lower pressing roller and the upper pressing roller for the sterile bag 7 to pass through becomes widened, so as to adapt to the sealing needs of packaging bags of different thicknesses.

[0068] The dual printing mechanism 506 is a push-pull dual printing mechanism, specifically comprising a printing base ribbon, a printing wheel, a print head, and an ink ribbon. Specifically, the dual printing mechanism 506 is slidably connected to the fixed mounting plate 507 via a slide rail assembly.
