The utility model utilizes the cooperation of a first mounting plate, a second mounting plate, a first sleeve, a second sleeve, a feeding shaft, a spring, a load-bearing plate, a connecting rod and a limiting plate to facilitate the limiting of coils of different widths, thereby avoiding the deviation of the cutting position where the slicing knife contacts the coil, thereby improving the quality of the slitting at the factory.

The moving block 403 is slidably connected to the rectangular slot 401, and the middle part of the moving block 403 is fixedly connected to a force roller 404. During the processing of the slitting machine, when the conveyed raw material is too tight, the raw material passes through the force roller 404 and exerts a certain force on it, so that the connecting spring 402 is compressed, driving the moving block 403 to slide upward in the rectangular slot 401 to avoid the raw material from being too tight and tearing. When the conveyed raw material is too loose, under the action of the gravity of the force roller 404 and the elastic potential energy of the connecting spring 402, the moving block 403 is driven to slide downward in the rectangular slot 401, thereby adjusting the tension of the raw material, avoiding the raw material from being too loose and entangled, and ensuring the stable operation of the slitting machine.
