As shown in figure 1, the zipper opening shearing mechanism of the utility model comprises a working table board 1 for conveying zipper materials. The working table plate 1 is provided with a material cutting groove 11, and a cutter mounting seat 2 is arranged below the material cutting groove 11. The cutter mounting seat 2 is provided with a cutter component, and the cutter component comprises a fixed cutter 3 which can extend out of the cutting groove 11, a movable cutter 4 which can be matched with the fixed cutter 3 to cut materials and a cutting motor 5 which is used for driving the movable cutter 4.

As shown in fig. 4, the stationary blade 3 has a rounded tip 3a for layering the fastener material, and a guide slope 3b extending downward from the rounded tip 3a for guiding the bottom layer of the fastener material to be cut. When the zipper material moves on the working bedplate 1, the arc tip 3a extends into the space between the zipper layer and the cloth layer, so that the two layers are layered. The cloth layer enters the material cutting position under the guidance of the guide inclined plane 3b and is automatically cut by the fixed knife 3 and the movable knife 4.

The bottom of the working table plate 1 is fixed with a rotary mounting seat 14, a rotary seat 12 is rotatably arranged on the rotary mounting seat 14 through a first rotary shaft 15, and the rotary seat 12 is fixedly connected with the cutter mounting seat 2.

The cutter mounting seat 2 is rotatably mounted below the working table plate 1 through a rotating seat 12, and a lifting driving cylinder 13 for driving the cutter mounting seat 2 to rotate is arranged at the bottom of the working table plate 1.

The cylinder body of the lifting driving cylinder 13 is movably connected with the cylinder mounting seat, and the piston rod of the lifting driving cylinder 13 is movably connected with the cutter mounting seat 2. The lifting driving cylinder 13 can control the position state of the cutter mounting seat 2, and the fixed cutter 3 is higher than the surface of the working bedplate 1 in the working state, so that the layering operation is facilitated; in a standby state, the cutter mounting seat 2 rotates to enable the fixed cutter 3 to retract into the material cutting groove 11, and the influence on material movement is avoided.

The cutter assembly comprises a shell 6, guide blocks 61 fixed on two sides inside the shell 6, and a sliding block 62 arranged between the guide blocks 61 in a sliding mode.
