In the present utility model, through the variable pitch mechanism 2, the distance between each cutter 32 can be quickly and accurately adjusted, eliminating the complicated steps of adjusting each cutter 32 one by one, shortening the time required to adjust the distance between the cutters 32, and making the relative position control between the cutters 32 more accurate;

[0023] Driving members 13 are fixedly connected to the upper ends of the two mounting plates 11, and the variable pitch mechanism 2 is lifted and lowered through the driving members 13. In the present utility model, the variable pitch mechanism 2 is lifted and lowered through the driving members 13, so that the distance between the cutter 32 and the printing material can be finely adjusted as needed to ensure the accuracy of cutting.

[0024] Further, the pitch-changing mechanism 2 includes a fixing plate 21. Both sides of the fixing plate 21 are fixedly connected to the telescopic ends of the two driving members 13. At both ends of one side of the fixing plate 21, connecting plates 22 are fixedly connected. At least two sliding rods 23 are fixedly connected between the two connecting plates 22. A plurality of connecting rods 24 are slidably connected to the sliding rods 23. Each connecting rod 24 changes its pitch through a guiding mechanism 25, and the guiding mechanism 25 is driven by a driving mechanism 26. In the present utility model, the driving mechanism 26 drives the guiding mechanism 25 to move, thereby driving a plurality of connecting rods 24 to move for pitch change, so that the distance between the cutting tools 32 can be adjusted as needed, thereby synchronously adjusting the distance between the multiple cutting tools 32 and maintaining the consistency of cutting.

[0025] Still further, the guiding mechanism 25 includes a driving plate 251. The driving plate 251 is slidably connected to the fixing plate 21. A plurality of guiding grooves 252 are formed on one side surface of the driving plate 251. A guiding column 253 is fixedly connected to one side of each connecting rod 24. The guiding column 253 is located in the guiding groove 252, and the guiding column 253 is slidably connected to the guiding groove 252. In the present utility model, when the driving mechanism 26 drives the driving plate 251 to move, at this time, the guiding column 253 guides the connecting rod 24 to move along the predetermined trajectory of the guiding groove 252, thereby realizing the precise adjustment of the distance between the cutting tools 32.

[0026] In addition, the driving mechanism 26 includes a linear groove 261 formed on the fixing plate 21. A connecting block 262 is fixedly connected to one side of the driving plate 251. The connecting block 262 is located in the linear groove 261. A fixing block 263 is fixedly connected to the upper end of the fixing plate 21. A screw rod 264 is rotatably connected to the fixing block 263. The screw rod 264 is threadedly connected to the connecting block 262. A knob 265 is fixedly connected to one end of the screw rod 264. In the present utility model, by rotating the knob 265 to drive the screw rod 264 to rotate, the rotation of the screw rod 264 drives the connecting block 262 to move in the linear groove 261 on the fixing plate 21 through a threaded action, thereby driving the driving plate 251 to move.

Fixing grooves 33 for placing the shaft of the cutter 32 are provided on both sides of the inner wall of the U-shaped frame 31. In this embodiment, one end of the fixing groove 33 penetrates through the U-shaped frame 31. The shaft of the cutter 32 rotates in the fixing groove 33. A fixing mechanism 34 for fixing the cutter 32 is further provided in the fixing groove 33. In the present utility model, since one end of the fixing groove 33 penetrates through the U-shaped frame 31, the shaft of the cutter 32 can be directly inserted into the fixing groove 33 from the outside of the U-shaped frame 31, thus realizing quick installation. When the cutter 32 needs to be replaced, only the fixing mechanism 34 needs to be released. At this time, the cutter 32 can be easily taken out through the open end of the fixing groove 33 without a complicated disassembly process.

[0028] In addition, the fixing mechanism 34 includes an installation hole 341 provided in the U-shaped frame 31. One side of the installation hole 341 penetrates through the U-shaped frame 31. An L-shaped limiting rod 342 for blocking the shaft of the cutter 32 is slidably connected in the installation hole 341. One end of the L-shaped limiting rod 342 is fixedly connected to a spring 343. One end of the spring 343 is fixedly connected to one end of the installation hole 341. In the present utility model, when the shaft of the cutter 32 is inserted into the fixing groove 33 and passes through the installation hole 341, the L-shaped limiting rod 342 is pushed by the elastic force of the spring 343 and will closely adhere to the shaft of the cutter 32, preventing its axial movement, thereby fixing the position of the cutter 32. If the cutter 32 needs to be replaced, the L-shaped limiting rod 342 can be manually pushed to make it leave the shaft of the cutter 32. At this time, the shaft of the cutter 32 can be freely taken out from the fixing groove 33, realizing the quick replacement of the cutter 32.

[0029] Working mode; during work, the knob 265 is rotated to drive the screw 264 to rotate. The rotation of the screw 264 drives the connecting block 262 to move in the linear groove 261 on the fixed plate 21 through the thread action, and then drives the driving plate 251 to move. At this time, the guide post 253 guides the connecting rod 24 to move along the predetermined track of the guide groove 252, and then drives a plurality of connecting rods 24 to move for variable pitch, so that the distance between the cutters 32 can be adjusted as needed. When the shaft of the cutter 32 is inserted into the fixing groove 33 and passes through the installation hole 341, the L-shaped limiting rod 342 is pushed by the elastic force of the spring 343 and will closely adhere to the shaft of the cutter 32, preventing its axial movement, thereby fixing the position of the cutter 32. If the cutter 32 needs to be replaced, the L-shaped limiting rod 342 can be manually pushed to make it leave the shaft of the cutter 32. At this time, the shaft of the cutter 32 can be freely taken out from the fixing groove 33, realizing the quick replacement of the cutter 32.
