a support shaft positioned at the left end of the die-cutting roller penetrates outside the rack positioned at the left side, a power shaft is coaxially and fixedly connected to the tail end of the support shaft positioned at the left end of the die-cutting roller, and a one-way bearing is coaxially assembled on the power shaft; the outer ring of the one-way bearing is coaxially and fixedly connected with a driving gear, and the inner ring of the one-way bearing is fixedly connected with a power shaft.
Compared with the prior art, the beneficial effects of the utility model reside in that:
(1) the transverse moving module drives the turning module to move parallel to the axial direction of the die-cutting roller, so that the roller surface of the die-cutting roller is turned and repaired on line, the die-cutting roller does not need to be stopped and removed, and the influence on the production efficiency is small;
(2) the power shaft of the die-cutting roller is driven by the one-way bearing, so that the situation that the roller surface of the compensating die-cutting roller cannot be matched with the cutting die roller to rotate synchronously due to the reduction of the linear speed is solved, and the die-cutting quality is guaranteed.
The invention is further described with reference to the drawings and embodiments.

Detailed Description
As shown in fig. 1 to 2, the wear repair compensation mechanism for the carton die-cutting roller comprises a left frame 1 and a right frame 1 which are separated, an axial horizontal die-cutting roller 2 is arranged between the frames 1, and a supporting shaft 3 which is rotatably matched with the frames 1 is coaxially and fixedly connected with the left end and the right end of the die-cutting roller 2;
a transverse moving module 4 and a turning module 5 which is driven by the transverse moving module 4 to move parallel to the axial direction of the die-cutting roller 2 are arranged between the frames 1, and the turning module 5 provides a turning tool 51 for turning the roller surface of the die-cutting roller 2;
the supporting shaft 3 positioned at the left end of the die-cutting roller 2 penetrates out of the rack 1 positioned at the left side, the tail end of the supporting shaft 3 positioned at the left end of the die-cutting roller 2 is coaxially and fixedly connected with a power shaft 31, and a one-way bearing 6 is coaxially assembled on the power shaft 31; the outer ring of the one-way bearing 6 is coaxially and fixedly connected with a driving gear 7, and the inner ring of the one-way bearing 6 is fixedly connected with a power shaft 31.
In the technical scheme, the wear repairing and compensating mechanism of the carton die-cutting roller 2 drives the turning module 5 to move in parallel to the axial direction of the die-cutting roller 2 through the transverse moving module 4, so that the roll surface of the die-cutting roller 2 is turned and repaired on line without stopping to remove the die-cutting roller 2, and the influence on the production efficiency is small. Particularly, in the case that the diameter of the die-cutting roller 2 is reduced due to the repair method, and further the roller surface of the die-cutting roller 2 cannot be matched with a knife-die roller for synchronous rotation due to the reduction of the linear velocity, the power shaft 31 of the die-cutting roller 2 is driven by the one-way bearing 6, so that the die-cutting roller 2 obtains a margin space for passive rotation when being matched with the knife-die roller, the linear velocity of the die-cutting roller 2 is compensated in a self-adaptive manner, and the die-cutting quality is guaranteed.
Further, the traverse module 4 is provided with a screw rod 41 which is axially parallel to the die-cutting roller 2, two ends of the screw rod 41 are rotationally matched with the frame 1, and the frame 1 is provided with a servo motor 42 for driving the screw rod 41 to rotate; the traverse module 4 is also provided with a linear guide rail 43 parallel to the screw rod 41, a sliding seat 44 in sliding fit is arranged on the guide rail, the sliding seat 44 and the screw rod 41 form transmission fit of the screw rod 41, and the turning module 5 is arranged on the sliding seat 44. Because the slide seat 44 and the screw rod 41 form a transmission fit of the screw rod 41, and the slide seat 44 is in sliding fit with the guide rail, the servo motor 42 drives the slide seat 44 and the turning module 5 on the slide seat 44 to move along the axial direction of the die-cutting roller 2, so that the surface of the die-cutting roller 2 is subjected to online turning repair by matching with the rotation of the die-cutting roller 2, the die-cutting roller 2 does not need to be stopped for removing, and the influence on the production efficiency is small.
Furthermore, the length direction of the guide rod of the turning tool 51 is arranged along the radial direction of the die cutting roller 2, and the cutting edge of the turning tool 51 is tangent to the roller surface of the die cutting roller 2.
