It should be noted that, in order to improve the maintenance efficiency, as shown in fig. 1, a maintenance cart 60 may be further added to the slitting system of the material tape, the maintenance cart 60 has a liftable operating platform, and the maintenance cart 60 moves through the wheels at the bottom end. The maintenance trolley 60 can be used in conjunction with the slitting table 10a provided in this embodiment to perform maintenance on the slitting knives 14 in the slitting table 10a provided in this embodiment. Wherein, the operator is located on the operation platform of the maintenance trolley 60, and makes the pushing cylinder 31 work to make the slitting knife 14 separate from the driving motor 30 and move for a certain distance, at this moment, the operator can directly draw out the slitting knife 14 for maintenance. The slitting knives 14 of the first slitting station 10a and the second slitting station 10a, respectively, can be acted upon by the lifting feature of the maintenance trolley 60.

It should be noted that the slitting workbench 10a is further provided with a safety protection net 70, and the safety protection net 70 is arranged above the slitting knife 14 to prevent hands and the like from being involved in the slitting knife 14.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
