[0002] The paper machine slitting device is a device used to cut large rolls of tissue paper or paper rolls into small pieces. It is commonly found in toilet paper production lines or processing plants. It is mainly composed of a paper roll support device, a cutting device, a transmission system, a control system, a safety device and an adjustment device. The working principle is to feed a large roll of tissue paper into the cutting device, cut it with a cutter, and finally obtain tissue paper blocks of the required size, thereby improving production efficiency and product quality.

[0003] The existing paper machine slitting device usually uses a conveying system to transport the rolled paper towels to the cutting device for slitting.
