Two groups of described front and back running roller, each group upper roll wheel is organized lower roll wheel with each and is respectively two, the conveyer belt that last group of lower roll wheel is connected with transmission shaft be arranged on two lower roll wheels on turning cylinder inner side.
In frame, be fixed with spring support, an adjusting screw(rod) and spring support are threaded connection, and spring is fixedly connected with adjustment screw rod one end.
Described spring is extension spring.
Subrack and the through hole of adjusting screw rod are caught on respectively in described extension spring two.
One end of described printing gripper shoe is bent downwardly, and curved end is fixedly connected with the sidewall of holding up of front subrack first end.
Described power transmission shaft is connected by bearing with support, and the turning cylinder of upper roll wheel is connected with support by bearing, and the turning cylinder of lower roll wheel is connected with subrack by bearing.
The present invention drives lower roll wheel to rotate by stepper motor through Timing Belt, the two groups of lower roll wheels in front and back synchronously rotate, simultaneously by the tension of spring, make lower roll wheel corresponding upper roll wheel be rotated by contacting friction simultaneously, and then print media is carried after by forward direction.
When thicker print media, such as thick envelope enters franking machine, effect due to spring, can be by the downward jack-up of lower roll wheel, and then thicker print media can successfully be carried, owing to printing gripper shoe, be arranged in the subrack of front roller wheel, print gripper shoe and also move down, smooth the passing through of print media energy; The printing surface of print media, no matter namely the thickness of the distance medium of the upper surface of print media and printhead is all substantially in par position, has improved the print quality of printing different-thickness medium.The printing that print speed of the present invention is fast, simple in structure, can adapt to different thickness media.
In subrack, offer the through hole consistent with power transmission shaft external diameter, subrack can be rotated around this fulcrum of power transmission shaft, the swing that before and after having facilitated, subrack is carried thickness part.
Adjusting screw(rod) is installed on spring support, is facilitated the elasticity of regulating spring, be conducive to send maintenance and the installation of part device.
The stiff end of printing support plate is bent downwardly, and compares the level installation of printing gripper shoe, has reduced while entering part and the touching of gripper shoe, makes into part smooth.
