If the piece of paper has entered the paper inlet of the full-width seal device, the second motor 14 is activated. The second motor 14 is fixed at the bottom of the housing and connected to the transmission gear set 3. The transmission gear set 3 is fixed on the housing, is located in the X-axis direction (the X-axis direction and the Y-axis direction are as shown in FIG. 1) and is connected to the upper friction wheel 4 and the lower friction wheel 5. The transmission gear set 3 is rotated by the second motor 14 when the second motor 14 is activated. The upper friction wheel 4 and the lower friction wheel 5 are further rotated as the transmission gear set 3 is rotated. The upper friction wheel 4 is located above the paper passing channel 17, and the lower friction wheel 5 is located below the paper passing channel 17, and the upper friction wheel 4 moves in an opposite direction to the lower friction wheel 5, such that a friction driving force is applied to the piece of paper, and the piece of paper is moved in the X-axis direction freely by the friction driving force.

The paper passing channel 17 includes a lower channel plate 15, a front channel upper plate 13, a sealing mechanism guide plate 9 and a seal bracket press plate 8. The lower channel plate 15 forms a lower surface of the whole paper passing channel 17, which is made of a whole piece of sheet metal part and extends to the paper outlet from the paper inlet, The lower channel plate 15 is drilled with multiple sets of small holes with each set having four small holes, and the small holes are located corresponding to the lower friction wheels respectively, such that the lower friction wheels 5 pass the small holes in the lower channel plate respectively to partly pass through the lower channel plate 15. The front channel upper plate 13, the sealing mechanism guide plate 9 and the seal bracket press plate 8 together form an upper surface of the whole paper passing channel 17. Specifically, the front channel upper plate 13 is drilled with multiple sets of small holes with each set having two small holes, and the small holes are located corresponding to the two upper friction wheels 4 adjacent to the paper inlet respectively, such that the two upper friction wheels 4 pass the two small holes in the front channel upper plate to partly pass through the front channel upper plate 13. The sealing mechanism guide plate is overlapped on the front channel upper plate, and the seal bracket press plate is overlapped on the seal bracket guide plate. The sealing mechanism guide plate and the seal bracket press plate both act as the channel to guide paper and ensure a smooth pass of the piece of paper. FIG. 3 is an enlarged schematic view of a detail A in FIG. 2. As shown in FIG. 3, the front channel upper plate 13 is bent to form a first horizontal surface 131, second horizontal surface 132, and a first inclined surface 133 connecting the first horizontal surface 131 and the second horizontal surface 132, in which the second horizontal surface 132 is lower than the first horizontal surface 131, and each of angels formed by the first inclined surface 133 and the first horizontal surface 131 and by the first inclined surface 133 and the second horizontal surface 132 is an obtuse angle. The function of this design is to provide a connection and guide between two discontinuous transmission channels, so as to prevent an front end of the piece of paper from tilting and further cause a jam. The sealing mechanism guide plate 9 is overlapped on the second horizontal surface 132 of the front channel upper plate 13 for fixing the sealing mechanism 6. The seal bracket press plate 8 is drilled with multiple sets of small holes with each set having two small holes, and the small holes are located corresponding to the two upper friction wheels 4 adjacent to the paper outlet respectively, such that the two upper friction wheels 4 pass into the corresponding small holes to partly pass through the seal bracket press plate 8.

The design of the paper passing channel described above is also referred to as an unidirectional imbricate design, which ensures a smooth paper pass, which thus prevents a paper jam.

(16) The component movable in the Y-axis direction includes a first motor 10 and a belt 11. The first motor 10 is connected to one end of the belt 11, and the sealing mechanism 7 is connected to the other end of the belt 11. The first motor 10, the belt 11 and the sealing mechanism 7 are all located in the Y-axis direction. When the piece of paper reaches the pre-set position on the X-axis, the first motor 10 is activated and the belt 11 is rotated, and the sealing mechanism 7 is further moved in the Y-axis direction as the belt 11 is rotated. The seal mechanism 7 executes a task of sealing after the seal mechanism 7 has moved to the pre-set position on the Y-axis.

(17) FIG. 5 is a schematic view of a seal replacing mechanism of the present application, in which hand-screwed screws are screwed off. As shown in FIG. 5, the full-width seal device further includes a hand-screwed screw 1 and a seal assembly press plate guiding column 2.

FIG. 6 is a schematic view showing the seal being replaced. As shown in FIG. 6, the sealing mechanism 7 includes a sealing mechanism spindle 12 and a seal 16 connected to each other. When being replaced, the seal 16 is overturned around the sealing mechanism spindle 12, which acts as a center of rotation, to be replaced with a new seal, then the seal replacing is completed. Compared with the conventional technology, the seal replacing above is more convenient and efficient.

(18) It is noted that the sealing mechanism is as shown in FIGS. 7a and 7b. FIG. 7a is a front schematic view. FIG. 7b is a back schematic view. The sealing mechanism includes a sealing mechanism bracket A1, a direct current motor A2, a cam A3, a U-shaped sensor A4, a seal assembly A5, a linear bearing assembly A6, the sealing mechanism spindle 12, a synchronous belt A8, a synchronous belt clamping block A9, a synchronous motor A10, a synchronous pulley fixing bracket assembly A11, synchronous pulleys (two) A12, the seal bracket press plate 8 and a guide wheel 14. The seal assembly A5, the linear bearing assembly A6, the synchronous belt clamping block A9 and the guide wheel 14 are fixed to the sealing mechanism bracket A1. The sealing mechanism spindle 12 passes through the linear bearing assembly A6 to provide guidance to the sealing mechanism in the Y-axis direction. The sealing mechanism is supported by the guide wheel 14, and the guide wheel 14 presses on the seal bracket press plate 8. The synchronous belt A8 is clamped into the synchronous belt clamping block. The seal assembly is moved in the Y-axis direction freely as the synchronous belt is moved by being pulled by the synchronous motor A10 via the synchronous pulleys A12. The synchronous pulley fixing bracket assembly A11 is used for fixing the synchronous pulleys. The sealing mechanism bracket is below the seal bracket press plate, and when the task of sealing is not executed, the sealing mechanism bracket is spaced from the seal bracket press plate by 2 mm, thus when the seal assembly is moved in the Y-axis direction, there is no frictional resistance between the sealing mechanism bracket and the seal bracket press plate. When the seal assembly executes the task of sealing, the cam is rotated by the direct current motor A2, and the cam will then apply a depressing force to the seal assembly, and when the seal assembly contacts the piece of paper and executes the task of sealing, the piece of paper and the seal are supported by the lower channel plate, and the sealing mechanism bracket will be moved upwards and a depressing force will be applied to the sealing mechanism bracket by the seal bracket press plate to make a seal on the piece of paper to be clear. When the cam is rotated by the direct current motor A2 for one turn and stop at a position corresponding to the U-shaped sensor A4, the task of sealing is completed.
