It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, a roller printing machine includes a conveying device 1, a printing roller 2 rotatably disposed above the conveying device 1, a first driving device 3 for driving the printing roller 2 to rotate, and a scraper mechanism 4 disposed above the printing roller 2; the axial direction of the printing roller 2 is vertical to the conveying direction of the conveying device 1; the scraper mechanism 4 comprises a scraper 401, a first hydraulic device 402 for driving the scraper 401 to move up and down, and a second hydraulic device 403 for driving the scraper 401 to move left and right.

Wherein a control device (not shown in the figure) is connected to each of the first hydraulic device 402 and the second hydraulic device 403. In actual operation, the operator can adjust the working states of the first hydraulic device 402 and the second hydraulic device 403 respectively through the control device. Specifically, when the scraper 401 needs to approach the printing roller 2 downwards, an operator controls the first hydraulic device 402 through the control device to enable the first hydraulic device 402 to push the scraper 401 downwards; when the doctor blade 401 needs to approach the printing roll 2 to the left, the operator controls the second hydraulic device 403 and causes the second hydraulic device 403 to pull the doctor blade 401 to the left. In practice, the doctor blade 401 is therefore moved towards and away from the printing cylinder 2 by the operator by hydraulic means. After the scraper 401 approaches the printing roller 2 and presses the cylindrical surface of the printing roller 2, if the pressure between the printing roller 2 and the scraper 401 is too large, the operator can control the first hydraulic device 402 or the second hydraulic device 403 to adjust the contact degree between the scraper 401 and the printing roller 2. Compared with the existing roller printing machine, the position of the scraper 401 does not need to be adjusted manually, the labor intensity of operators is reduced, and meanwhile, the hydraulic device is controlled by the control device, so that the adjustment process of the scraper 401 each time can be standardized, the pressure between the scraper 401 and the printing roller 2 is consistent, and the printing quality can be improved.

Referring to fig. 1, in another embodiment, two parallel supporting plates 5 are disposed above the conveying device 1; the supporting plate 5 is used for installing the printing roller 2; specifically, the supporting plates 5 are respectively arranged on two sides of the conveying device 1 along the conveying direction of the conveying device 1; the printing roller 2 is arranged between the supporting plates 5, and a rotating shaft is fixedly arranged in the middle of the printing roller 2 in a penetrating manner; and two ends of the rotating shaft are respectively movably connected with the supporting plate 5.

Meanwhile, the first driving device 3 can be installed at the outer side of any one of the supporting plates 5, and the output shaft of the first driving device 3 can be connected with a rotating shaft which penetrates out of the supporting plate 5 through a coupler. When the first driving device 3 works normally, the rotating shaft is driven to rotate, and then the printing roller 2 is driven through the rotating shaft, so that the printing roller 2 keeps a working state.

Referring to fig. 1 and 3, in another embodiment, the operator may use both cylinders as the first hydraulic device 402 and the second hydraulic device 403.

Further, in the above embodiment, the piston rod of the first hydraulic device 402 is connected with the first pull rod 9 connected with the scraper 401, and the piston rod of the second hydraulic device 403 is connected with the second pull rod 10 connected with the hanger bar 8. Through additionally arranging the pull rod connected with the piston rod of the air cylinder, the situation that the scraper 401 cannot be in contact with the printing roller 2 due to the limitation of the length of the piston rod can be avoided.
