The die cutting roller in the prior art is used as a cutting board in a die cutting process, and the biggest problem is roller surface abrasion caused by cutting by matching with a cutter. In order to enhance the damage resistance of the die-cutting roller, the prior art mostly adopts a metal smooth roller with a hard metal layer plated on the outer surface as the die-cutting roller, or adopts a mode of mounting a serrated knife on a knife die roller to reduce the matching surface acting on the die-cutting roller as much as possible. Nevertheless, surface wear of die-cutting rolls is unavoidable, and a die-cutting roll with further increased wear resistance is desired.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome foretell prior art weak point, provide a carton die-cutting roller of axial displacement compensation endurance loss, its technical scheme as follows.
The carton die-cutting roller with the damage compensated by axial movement comprises a left frame and a right frame which are separated, wherein an axial horizontal die-cutting roller is arranged between the frames, and a supporting shaft which is in running fit with the frames is coaxially and fixedly connected with the left end and the right end of the die-cutting roller;
a linear bearing which is coaxially sleeved and matched with the supporting shaft is arranged on the rack so as to ensure that the die-cutting roller obtains a displacement stroke in the axial direction;
the supporting shaft at the left end of the die-cutting roller penetrates out of the rack at the left side from the linear bearing, the tail end of the supporting shaft at the left end of the die-cutting roller is coaxially and fixedly connected with a power shaft, and the surface of the power shaft is provided with a key groove which is parallel to the axial direction;
the support shaft positioned at the right end of the die-cutting roller penetrates out of the rack positioned on the right side from the linear bearing, and the rack is provided with an axial driving mechanism connected with the tail end of the support shaft at the outer side, and the axial driving mechanism drives the die-cutting roller to move along the axial direction.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the die-cutting roller is driven by the axial driving mechanism to move along the axial direction, so that the working surface of the die-cutting roller matched with the knife die roller at each time has different axial positioning, the abrasion of the die-cutting roller matched with the knife die roller at each time is more uniformly dispersed, and the abrasion resistance of the die-cutting roller is further enhanced.
The invention is further described with reference to the drawings and embodiments.

Detailed Description
As shown in fig. 1 and 2, the carton die-cutting roller with axial movement compensation and damage resistance comprises a left and a right separated frames 1, wherein the frame 1 is provided with a die-cutting roller 2 which is axially horizontal, and a supporting shaft 3 which is rotatably matched with the frame 1 is coaxially and fixedly connected with the left and the right ends of the die-cutting roller 2;
a linear bearing 4 which is coaxially sleeved and matched with the supporting shaft 3 is arranged on the frame 1 so as to ensure that the die-cutting roller 2 obtains a displacement stroke in the axial direction;
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 from the linear bearing 4, 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 5, and the surface of the power shaft 5 is provided with a key slot 51 which is arranged in parallel to the axial direction;
the supporting shaft 3 positioned at the right end of the die-cutting roller 2 penetrates out of the rack 1 positioned at the right side from the linear bearing 4, the rack 1 is externally provided with an axial driving mechanism 6 connected with the tail end of the supporting shaft 3, and the die-cutting roller 2 is driven by the axial driving mechanism 6 to axially displace.
In the technical scheme, the carton die-cutting roller system with axial movement compensation and damage resistance is connected with an external rotation driving mechanism through a power shaft 5 so as to realize the driving of the die-cutting roller 2; the die-cutting roller 2 is driven to axially displace by the axial driving mechanism 6, so that the working surface of the die-cutting roller 2 matched with the cutting die roller 9 at each time has different axial positioning, the abrasion caused by the die-cutting roller 2 matched with the cutting die roller 9 at each time is more uniformly dispersed, and the abrasion resistance of the die-cutting roller 2 is further enhanced; the key groove 51 is formed parallel to the axial direction of the power shaft 5 and also matches the axial moving stroke of the die cutting roll 2.
As an improvement of the above technical solution, the axial driving mechanism 6 includes a servo motor 61 fixedly installed outside the frame 1, the servo motor 61 has an output shaft 62 vertically arranged, a rotating disc 63 is fixedly connected to the end of the output shaft 62, and a driving shaft 64 eccentrically matched with the output shaft 62 is arranged on one side of the rotating disc 63 away from the output shaft 62; the end of the supporting shaft 3 positioned at the right end of the die-cutting roller 2 is fixedly connected with a guide disc 7, and the periphery of the guide disc 7 is provided with an annular guide groove 71 coaxially aligned with the supporting shaft 3; the distal end of the drive shaft 64 is placed in the annular guide groove 71, and the distal end of the drive shaft 64 is slidably fitted to the side wall of the annular guide groove 71.
Since the drive shaft 64 is eccentrically fitted to the output shaft 62, the drive shaft 64 is caused to perform a circular motion with respect to the output shaft 62, so that the drive shaft 64 can obtain a reciprocating stroke in the axial direction of the die cutting roll 2. Considering that the end of the driving shaft 64 is disposed in the annular guide groove 71, the reciprocating stroke of the driving shaft 64 along the axial direction of the die-cutting roller 2 is axially moved by pushing and pulling the die-cutting roller 2 by the guide disk 7, thereby realizing the axial movement compensation of the working surface of the die-cutting roller 2.
Further, the distal end of the driving shaft 64 is provided with a ball bearing 65 coaxially installed, and an outer circumferential surface of the ball bearing 65 is engaged with a side wall of the annular guide groove 71.
In a preferred embodiment, the turntable 63 is circular in axial projection, as shown in fig. 3.
Various other modifications and alterations of the disclosed structure and principles may occur to those skilled in the art, and all such modifications and alterations are intended to be included within the scope of the present invention.
