During its production and processing, the base paper roll is first re-rolled into a toilet paper roll roll of the required diameter. However, the length of this paper roll is very long and cannot be directly used for packaging and sale. Therefore, the paper roll needs to be cut and cut into toilet paper rolls of various lengths sold on the market.

[0003] The traditional cutting method is to place the paper roll on the cutting table, manually push it to the cutting knife position, and then the cutting knife moves from one side of the paper roll to the other side to cut it, and then the cutting knife returns to its original position, and the operator pushes the paper roll forward again, and the long paper roll is cut into sections of paper rolls in this way. However, the disadvantage of this device is that the paper roll needs to be pushed forward manually, which is time-consuming and labor-intensive, and the cutting efficiency is low. In addition, it is also dangerous to manually push the paper roll close to the cutting knife. Therefore, the utility model proposes a large paper roll slitting device to solve the above problems.
