In this embodiment, one end of the ink wiping cloth 9 sequentially penetrates through the interiors of the first guide piece 13, the second guide piece 14 and the third guide piece 15 and extends to the outside of the placing frame 1, the first guide piece 13, the second guide piece 14 and the third guide piece 15 play a role in preliminary limiting the ink wiping cloth 9, the situation that the ink wiping cloth 9 falls when the ink wiping wheel body 2 and the feeding wheel body 3 move downwards is avoided, and the usability of the device is improved.

Specifically, the inside of rack 1 is fixed and is provided with first spacing post 16, first spacing post 16 is located wipes black pinch roller 10 under, the inside of rack 1 is fixed and is provided with the spacing post 17 of second, the spacing post 17 of second is located pay-off pinch roller 11 under, first spacing post 16 with wipe black pinch roller 10 between the distance specification be greater than the spacing specification between the spacing post 17 of second and the pay-off pinch roller 11.

In this embodiment, the distance between the first limit column 16 and the ink wiping pressing wheel 10 is greater than the distance between the second limit column 17 and the feeding pressing wheel 11, when the cylinder 8 drives the ink wiping wheel body 2 and the feeding wheel body 3 to ascend, the ink wiping wheel body 2 firstly drives the ink wiping cloth 9 to abut against the ink wiping pressing wheel 10 to rotate clockwise, so that the ink wiping cloth 9 moves, before the ink wiping cloth 9 on the surface of the feeding wheel body 3 contacts with the feeding pressing wheel 11, the actual walking length of the ink wiping cloth 9 continuously ascending is equal to the rotating distance of the ink wiping wheel driven by the ascending cylinder 8, and the use of a user is facilitated.

The utility model discloses a theory of operation and use flow: when the ink wiping wheel is used, the positions of the ink wiping wheel body 2 and the feeding wheel body 3 in the figures 1 to 3 are the highest points, the positions of the ink wiping wheel body 2 and the feeding wheel body 3 in the figures 4 to 6 are the lowest points, the ink wiping pressing wheel 10 and the feeding pressing wheel 11 press the ink wiping cloth 9 on the surfaces of the ink wiping wheel body 2 and the feeding wheel body 3 at the highest points, the outer surfaces of the ink wiping wheel body 2 and the feeding wheel body 3 are wrapped with soft rubber round rollers, (directional bearings are arranged inside the ink wiping wheel body 2 and the feeding wheel body 3 and only can rotate clockwise by taking the figure 3 as reference), the first spring friction plate 6 and the second spring friction plate 7 respectively press the ink wiping wheel body 2 and the feeding wheel body 3 to generate friction force, the air cylinder 8 is closed to move downwards, so that the air cylinder 8 drives the supporting connecting rod to link the ink wiping wheel body 2 and the feeding wheel body 3 to descend to the lowest points together, and the ink wiping wheel body 2 and the feeding wheel body 3 can only rotate clockwise, the ink wiping wheel body 2 and the feeding wheel body 3 are not rotated in the downward movement process, the ink wiping cloth 9 pressed on the ink wiping wheel body 2 and the feeding wheel body 3 does not rotate clockwise or move, the ink wiping cloth 9 is cloth with strong water absorption, is placed on the placing frame 1 in a coiled material mode and is inserted in gaps, can be easily rotated, and enough length can be designed and reserved according to actual needs;

when the cloth strip moves at the lowest point, the first limiting column 16 and the second limiting column 17 respectively block the ink wiping pressing wheel 10 and the feeding pressing wheel 11, enough gaps are reserved between the ink wiping pressing wheel 10 and the ink wiping wheel body 2 and between the feeding pressing wheel 11 and the feeding wheel body 3, the ink wiping cloth 9 is in a loose state without the pressing of the ink wiping pressing wheel 10 and the feeding pressing wheel 11, so that the ink wiping cloth 9, the ink wiping pressing wheel 10 and the feeding pressing wheel 11 (the ink wiping pressing wheel 10 and the feeding pressing wheel 11 only show that the blocking edges of the figure 5 and the figure 6 are cut away for convenience), the cloth strip is recalibrated, and the cloth strip cannot deviate in the moving process;

when the cylinder 8 is started to drive the ink wiping wheel body 2 and the feeding wheel body 3 to move upwards to the highest point, the friction force between the first spring friction plate 6 and the ink wiping wheel body 2 and the friction force between the second spring friction plate 7 and the feeding wheel body 3 enable the ink wiping wheel body 2 and the feeding wheel body 3 to rotate clockwise (clockwise rotation with reference to the figure 3), the limit positions of the first limit column 16 and the second limit column 17 are different, when the cylinder 8 drives the ink wiping wheel body 2 and the feeding wheel body 3 to ascend, the ink wiping wheel body 2 firstly drives the ink wiping cloth 9 to abut against the ink wiping pressing wheel 10 to rotate clockwise, the ink wiping cloth 9 moves, before the ink wiping cloth 9 on the surface of the feeding wheel body 3 is contacted with the feeding pressing wheel 11, the continuously ascending ink wiping cloth 9 walks by the actual length which is equal to the distance of the rotation of the ink wiping wheel driven by the ascending cylinder 8, at the moment, the ink wiping cloth 9 on the surface of the feeding wheel body 3 is contacted with the feeding pressing wheel 11 to be pressed tightly, and because the outer diameter of the ink wiping wheel friction circle 4 is larger than that of the feeding wheel friction circle 5, the surface linear velocity of the corresponding ink wiping wheel body 2 is larger than that of the feeding wheel body 3, so that the ink wiping cloth 9 clamped by the opposite surfaces of the ink wiping wheel body 2 and the ink wiping pressing wheel 10 and the opposite surfaces of the feeding wheel body 3 and the feeding pressing wheel 11 slides, and cloth strips between the ink wiping pressing wheel 10 and the feeding pressing wheel 11 are in a tensioned state, and the ink wiping is convenient;

the cylinder 8 is in a movement period from the highest point to the lowest point when the cylinder 8 descends, the ink wiping cloth 9 moves for a corresponding distance, the ink wiping state is in a state that the cylinder 8 ascends to the highest point, the position A in fig. 3 is the highest point, the tangent point position of the highest point A is the ink wiping position, the bottom surface of the ink wiping cloth contacts the point A, the ink wiping bottom surface (reference figure 3 is taken as a reference) moves from right to left to wipe ink, the bottom surface is wiped to clean one section of the ink wiping cloth 9 which has wiped the bottom surface, the section of the ink wiping cloth 9 is wet and dirty, the cylinder 8 moves to the lowest point and then moves to the highest point for a period, (the dirty ink wiping cloth 9 moves for a certain distance), the brand new clean ink wiping cloth 9 moves to the tangent point of the A, the next bottom surface to be wiped is waited, and the operation of the device is completed.
