Embodiment
Below in conjunction with the accompanying drawing of the present invention, the technical scheme to the embodiment of the present invention carries out clear, complete description.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of disclosed paper transport device, including frame 1, paper are defeated
Send band component 2, vacuum cup 3, drive mechanism 4, active roller group 5, and return idler group 6, the drive mechanism 4, active
Roller group 5 and return idler group 6 are arranged in frame 1.Active roller group 5 is connected with drive mechanism 4, and drive mechanism 4 drives
Active roller group 5 is rotated, and then passes through the rotation of the drive return idler of sheet transfer belt component 2 group 6.Sheet transfer belt component 2
The active roller group 5 and the periphery of return idler group 6 are looped around, it is as active roller group 5 is rotated and is rotated.Vacuum cup 3
It is similarly installed in frame 1, and in sheet transfer belt component 2.When sheet transfer belt component 2 is rotated, vacuum cup 3 will be treated
Paper adsorption is conveyed on sheet transfer belt component 2, sheet transfer belt component 2 exports paper by frictional force.
In the present embodiment, the drive mechanism 4 is located at the top of return idler group 6, and the active roller group 5 is located at driven
