This machine is commonly used in industrial manufacturing, woodworking, metal processing and other fields, and can perform various precise cutting and processing operations.

[0003] According to a Chinese patent document with the publication number CN213165812U, which discloses a round knife die-cutting machine belonging to the technical field of die-cutting equipment, including a machine body, a cutter and a bottom roller arranged in parallel on the machine body. An installation groove is provided on one side of the machine body. An installation seat is slidably arranged in the installation groove along the height direction of the machine body. Both ends of the bottom roller are fixed to the two side installation seats through connecting bearings. Adjustment grooves penetrating into the installation groove are symmetrically opened on the two side walls of the machine body perpendicular to the bottom roller. An adjustment rod penetrates through the bottom of the installation seat, and both ends of the adjustment rod extend out of the adjustment groove and are provided with locking bolts. A buffer assembly is arranged between the installation seat and the bottom of the installation groove.

[0005] Therefore, it is urgent to improve the deviation rectifying device of the round knife machine to solve the above existing problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a deviation rectifying device for a round knife machine. By setting a deviation rectifying mechanism, when the sensor detects that the material on the deviation rectifying roller is offset, the sensor sends a signal to the controller, and the controller controls the electric push rod to drive the deviation rectifying part to move on the support frame, and then drives the deviation rectifying roller to move, so as to adjust the position of the material on the deviation rectifying roller, thereby preventing the cut materials from not meeting the quality requirements due to position deviation, and thus greatly improving the cutting accuracy of the round knife machine.

[0007] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

Detailed implementation mode

[0027] The following will cooperate with the drawings and embodiments to elaborate in detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0028] As Figures 1 - 5 shown, the deviation rectifying device of the circular knife machine provided in this embodiment includes a frame 1 and a conveyor line 2 rotatably arranged on the frame 1. A deviation rectifying mechanism 3 is fixedly installed on the frame 1. A flattening mechanism 4 is arranged on one side of the deviation rectifying mechanism 3, and a die-cutting mechanism 5 is arranged on the other side of the deviation rectifying mechanism 3.

A deviation rectifying roller 306 is rotatably connected to the support frame 305 through a rotating rod. Electric push rods 307 are arranged on both sides of the deviation rectifying roller 306. One end of the electric push rod 307 is hinged to the fixed frame 301. The output end of the electric push rod 307 is fixedly installed with a connecting block 308. The connecting block 308 is hinged to the deviation rectifying part 304. The upper end of the connecting block 308 is fixedly installed with a sensor 309. The sensor 309 and the electric push rod 307 are electrically connected to the controller 302. When the sensor 309 detects that the material on the deviation rectifying roller 306 is offset, the sensor 309 sends a signal to the controller 302. The controller 302 controls the electric push rod 307 to drive the deviation rectifying part 304 to move on the support frame 305, and then drives the deviation rectifying roller 306 to move, so as to adjust the position of the material on the deviation rectifying roller 306, thereby preventing the cut material from not meeting the quality requirements due to position deviation, and thus greatly improving the cutting accuracy of the circular knife machine.

[0030] Furthermore, as Figure 4As shown in the figure, the flattening mechanism 4 includes two cylinders 401. The two cylinders 401 are fixedly installed on the frame 1, and the output ends of the two cylinders 401 are fixedly connected with a connecting plate 402. A flattening plate 403 is arranged below the connecting plate 402. A flattening roller 404 is rotatably connected to the flattening plate 403 through a rotating rod.

The cylinder 401 drives the connecting plate 402 to move up and down, and then drives the flattening roller 404 to move. The flattening roller 404 is attached to the material, and then the material is flattened, thereby avoiding the phenomenon of wrinkling during the cutting process of the material and affecting the normal use of the material. The buffer spring 405 can prevent the excessive pressure of the cylinder 401 and damage the material by the flattening roller 404.

By rotating the screw rod 508, the slider 506 is driven to slide inside the sliding groove 505 to adjust the distance between the pressure roller 507 and the cutter roller 504. Then, by starting the driving motor 502 to drive the rotating shaft 503, the cutter roller 504 is driven to cut the material, so as to facilitate the cutter roller 504 to cut materials of different thicknesses.

[0032] Still further, as Figure 1 shown, a feeding reel 6 is fixedly installed on one side of the frame 1. The feeding reel 6 corresponds to the deviation rectifying mechanism 3, the flattening mechanism 4 and the die-cutting mechanism 5.
