[0009] The beneficial effects of the utility model are:

[0010] 1. The upper and lower disc blades are fitted together to form a scissor-like structure, which can ensure stable slitting. When the feed roller on the feed rack is feeding, the adjustment screw is moved left and right through the adjustment seat, driving the adjustment column to adjust the left and right position of the apex on the feed roller. The position of the two different rubber seams of the apex corresponds to the upper and lower disc blade edges, which facilitates precise slitting. The adjustment column can prevent the slitting reaction force from affecting the stable front and back feeding of the apex during the slitting process, avoiding the deviation of the apex feeding direction due to the slitting reaction force, which helps to improve the slitting accuracy. When the position of the different rubber seams of the apex is not in the center position, the left and right adjustment screws are used to control the adjustment columns on the left and right adjustment seats respectively to adjust the left and right positions of the apex in the feeding direction.

[0011] 2. During long-term use, the tapered roller bearings that connect the upper and lower cutter shafts are subject to thrust, which can easily cause a gap between the cutting edges of the upper and lower disc blades, affecting the slitting accuracy. By controlling the adjusting bolt to push the adjusting ring, the adjusting ring pushes the cutter shaft through the inner ring of the tapered roller bearing, so that the disc on the cutter shaft fits against the other disc to eliminate the gap, which is beneficial to ensure accuracy.
