[0022] The following further describes the present utility model in detail with reference to the embodiments:

[0023] Embodiment 1

[0024] As Figures 1-4 shown, the present utility model provides a die-cutting mechanism of a die-cutting machine, which includes a transmission frame 1. A leveling mechanism 4 is installed on the surface of the transmission frame 1. A support frame 2 is installed on the surface of the transmission frame 1. A die-cutting mechanism 3 is installed on the surface of the support frame 2. The die-cutting mechanism 3 includes a driving cylinder 30. The driving cylinder 30 is fixedly connected to the surface of the support frame 2. A moving rod 31 is installed at the output end of the driving cylinder 30. A placing block 32 is installed at one end of the moving rod 31. Connecting blocks 34 are fixedly connected to both sides of the placing block 32. A fixing rod 35 is threadedly connected to the surface of the connecting block 34. A die-cutting knife 33 is installed at one end of the fixing rod 35. A clamping component is arranged above the die-cutting knife 33. The clamping component includes a U-shaped clamping block 36 fixedly connected above the die-cutting knife 33. A hollow groove 37 is opened at the lower side of the placing block 32. The U-shaped clamping block 36 is movably clamped inside the hollow groove 37. A spring 45 is fixedly connected inside the placing block 32 at the hollow groove 37. One end of the spring 45 is fixedly connected to a support connecting rod 40. An inclined block 38 is fixedly connected to one side of the support connecting rod 40. The inclined block 38 is arranged inside the hollow groove 37. A sliding groove 41 is opened at the upper side of the placing block 32. A pull rod 39 is fixedly connected to the outside of the support connecting rod 40. And the pull rod 39 is slidably connected inside the sliding groove 41. An expansion rod 44 is arranged inside the placing block 32 at the hollow groove 37. One end of the expansion rod 44 is fixedly connected to the placing block 32. The other end of the expansion rod 44 is fixedly connected to the support connecting rod 40. And the expansion rod 44 is arranged inside the spring 45. A first hollow groove 43 is opened inside the placing block 32. The first hollow groove 43 is communicated with the hollow groove 37. A stop block 42 is fixedly connected to one side of the pull rod 39. And the stop block 42 is slidably connected inside the first hollow groove 43. The leveling mechanism 4 includes an installation frame 46. The installation frame 46 is fixedly connected to the surface of the transmission frame 1. A rotating bolt 47 is threadedly connected to the surface of the installation frame 46. A moving disk 48 is threadedly connected to the surface of the rotating bolt 47. A leveling shaft 49 is sleeved at one end of the moving disk 48;

[0025] Specifically, the transfer rack 1 is used to transfer the die-cut parts. During the transfer, the leveling shaft 49 levels the die-cut parts. By twisting the rotating bolt 47, the rotating bolt 47 drives the moving plate 48 to move up and down, and the moving plate 48 drives the leveling shaft 49 to move up and down. Thus, it is possible to flexibly adjust the leveling shaft 49 according to the size of the die-cut parts. The placing block 32 is located inside the hollow groove 37 and is fixedly connected with a spring 45. One end of the spring 45 is fixedly connected with a support connecting rod 40. The spring 45 can play a role in connecting the support connecting rod 40. At the same time, the spring 45 can also play a reset role for the support connecting rod 40 through its own elasticity. One side of the support connecting rod 40 is fixedly connected with an inclined block 38, and the inclined block 38 is arranged inside the hollow groove 37. The lower side of the inclined block 38 is set as an inclined surface. When the inclined block 38 moves into the hollow groove 37, it will squeeze the inclined surface of the inclined block 38, causing the inclined block 38 to move. And the return-shaped clamping block 36 is in the shape of a reversed N. This enables the inclined block 38 to be stuck and not easy to move, so that the die-cutting knife 33 can be connected to the lower side of the placing block 32. When the inclined block 38 moves, it will squeeze the spring 45 to contract through the support connecting rod 40. When the inclined block 38 is located in the concave part of the return-shaped clamping block 36, the spring 45 will release elastic force to automatically pop the inclined block 38 into the inside of the return-shaped clamping block 36, thus achieving the effect of automatically clamping the return-shaped clamping block 36. A chute 41 is opened on the upper side of the placing block 32. A pull rod 39 is fixedly connected to the outside of the support connecting rod 40, and the pull rod 39 is slidably connected inside the chute 41. While connecting the inclined block 38 and the spring 45, the support connecting rod 40 can also connect the pull rod 39 and play a fixing role for the pull rod 39. When the pull rod 39 is moved by the staff, the pull rod 39 can drive the support connecting rod 40 to move together, and make it more convenient for the support connecting rod 40 to be moved when needed. The placing block 32 can play a role in limiting the stop block 42 through the first hollow groove 43. When the pull rod 39 drives the stop block 42 to move, the stop block 42 can move inside the first hollow groove 43 without restricting the movement of the pull rod 39.

[0026] Next, the working principle of the die-cutting mechanism of this die-cutting machine will be specifically described.

[0027] As Figures 1-4As shown, the die-cutting knife 33 can cut the material to be processed. When the die-cutting knife 33 needs to be replaced after long-term use, the staff can first pull the pull rod 39. At the same time, the pull rod 39 will drive the support connecting rod 40 to move. At the same time, the support connecting rod 40 will squeeze the spring 45. When the spring 45 is under pressure, it will contract. At the same time, the inclined block 38 will be driven by the support connecting rod 40 to move together. When the inclined block 38 moves a certain distance driven by the pull rod 39, the inclined block 38 will cancel the limit on the return-shaped clamping block 36, so that the return-shaped clamping block 36 is no longer stuck. At this time, the return-shaped clamping block 36 can be taken out from the inside of the hollow groove 37, and the effect of separating the die-cutting knife 33 and the placing block 32 can be achieved, so as to facilitate the staff to replace the new die-cutting knife 33. The device connects the die-cutting knife 33 and the placing block 32 through a clamping mechanism, rather than a welding method, which makes it more convenient for the staff to disassemble the die-cutting knife 33 when replacing the die-cutting knife 33. Thus, the problem that it is very inconvenient to replace and disassemble the die-cutting knife of most die-cutting devices can be solved.

[0028] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
