[0021] This application discloses a paper cutter that facilitates changing the cutting edge, such as... Figure 1 and Figure 2 As shown, the system includes a platform 2, support legs 21, and a cutting table 22. A drive mechanism 3 for driving the cutting table 22 to rotate is installed on the platform 2. The drive mechanism 3 includes a frame 31 installed on the top of the platform 2 and a drive motor 32 installed vertically in the frame 31.

The drive motor 32 is speed-controlled by a frequency converter. The output shaft of the drive motor 32 drives the rotating shaft 33 to rotate at low speed. A mounting frame 23 is installed on the top of the platform 2. A clamping mechanism 4 for pressing the paper stack 1 and a cutting mechanism 6 for cutting the edges of the paper stack 1 are installed on the mounting frame 23. When it is necessary to change the cutting edge of the paper stack 1, the drive motor 32 is started first. At this time, the output shaft of the drive motor 32 drives the rotating shaft 33 to rotate. The rotation of the rotating shaft 33 drives the cutting table 22 to rotate. The rotation of the cutting table 22 can change the cutting edge of the paper stack 1. In summary, the drive mechanism 3 is set to facilitate the change of the cutting edge of the paper stack 1, thereby reducing the labor intensity of workers.

[0022] like Figure 1 and Figure 2 As shown, the clamping mechanism 4 includes a first cylinder 41 vertically mounted at the bottom of the mounting frame 23 and a pressure frame 42 horizontally mounted on the piston rod of the first cylinder 41.

In summary, the clamping mechanism 4 facilitates the clamping of the paper stack 1.

[0023] like Figure 2 and Figure 3 As shown, the pressure frame 42 is detachably connected to the piston rod of the first cylinder 41 via the first connecting component 5.

When the tool holder 62 needs to be installed, the piston rod of the second cylinder 61 is first inserted into the sleeve 71 by moving the tool holder 62, and then the piston rod of the second cylinder 61 is fixedly connected to the sleeve 71 by the second fastening bolt 72, thereby allowing the tool holder 62 to be installed; in summary, the second connecting assembly 7 facilitates the installation of the tool holder 62.

[0028] like Figure 1 and Figure 2As shown, a movable plate 8 is fixedly connected to the top of the second cylinder 61, and an adjustment mechanism 9 for fine-tuning the position of the movable plate 8 is installed on the mounting bracket 23. The adjustment mechanism 9 facilitates the horizontal adjustment of the movable plate 8, thereby facilitating the horizontal adjustment of the cutter 63.
