When in use, the longitudinal knife 6 is reinforced by the reinforcing blade 16, thereby ensuring that the die-cutting of the longitudinal knife 6 is more stable when in use.
[0021] From the above description, it can be seen that the utility model has the following beneficial effects: when in use, the horizontal knife 5 is installed through the sliding opening 7, and when in use, the horizontal knife 5 is driven to extend and retract by adjusting the electric rod 8, and at the same time, the vertical knife 6 is driven to move and adjust by adjusting the screw 11 and the adjusting nut 10, so that the size of the die cutting can be quickly adjusted.
[0022] Example 2: Please refer to Figures 1 to 3As shown, on the basis of the first embodiment, the utility model provides a technical solution: a total of four longitudinal knives 6 are provided, two of which are located at the two ends of the middle outer sleeve 3, and the remaining two longitudinal knives 6 are installed in the middle of the middle outer sleeve 3 through an adjusting block 9, an adjusting nut 10 and an adjusting screw 11; the adjusting block 9, the adjusting nut 10 and the adjusting screw 11 are symmetrically installed at the two ends of the inner main roller 4, and the ends of the adjusting screw 11 are connected by a transmission mechanism 12.
