[0020] Depend on Figure 1-6 The utility model includes a bottom plate 1, and an inverted L-shaped support frame 2 is fixedly installed at the middle position of both sides of the bottom plate 1, and the horizontal and vertical parts of the two support frames 2 are located above the bottom plate 1. A frame 3 that can move up and down is arranged between the two support frames 2, and a top plate 5 that can move up and down is arranged between the frames 3. A mounting groove is opened at the bottom of the top plate 5, and a cutting knife 7 is installed in the mounting groove. A knife groove 8 is opened at the bottom of the frame 3, and the bottom end of the cutting knife 7 is movably inserted in the knife groove 8 at the bottom of the frame 3. Two second hydraulic rods 6 are fixedly installed on the top of the frame 3, and the telescopic ends of the two second hydraulic rods 6 pass through the top of the frame 3 and are fixedly connected to the top of the top plate 5. When cutting the foam tape, the second hydraulic rod 6 is first controlled to drive the top plate 5 moves up to the top between the frames 3, and then places the foam tape on the bottom plate 1 and below the frame 3, and then controls the first hydraulic rods 4 on the two first support frames 2 to push the frame 3 down to its bottom and contact with the top of the foam tape, and then controls the second hydraulic rods 6 to push the top plate 5 down between the frames 3, so that the cutting knife 7 at the bottom of the top plate 5 passes through the knife groove 8 at the bottom of the frame 3 to cut the foam tape, and after the cutting is completed, the second hydraulic rod 6 contracts and drives the top plate 5 and the cutting knife 7 to move up together, so that the cutting knife 7 is lifted back to the knife groove 8 at the bottom of the frame 3, and when the cutting knife 7 moves up, the bottom of the frame 3 is always pressed on the top of the foam tape, so as to avoid the cutting knife 7 from pulling up the cut foam tape when moving up.

[0021] like Figure 3 and Figure 4As shown, vertical first positioning rods 9 are fixedly installed between the two ends of the top and bottom of the inner wall of the frame 3, first through holes 10 are opened at the tops of the two ends of the top plate 5, and the first through holes 10 at the two ends of the top plate 5 are respectively movably connected to the two first positioning rods 9 between the frames 3. The first positioning rods 9 can make the top plate 5 more stable when moving up and down between the frames 3, thereby avoiding the cutting knife 7 from being deflected when cutting the foam tape.

[0022] like Figure 1 and Figure 2 As shown, a first hydraulic rod 4 is fixedly installed on the top of the horizontal parts of the two support frames 2, and the telescopic ends of the two first hydraulic rods 4 penetrate the horizontal parts of the corresponding support frames 2 and are respectively fixedly connected to the two ends of the top of the frame 3. By controlling the telescopic first hydraulic rod 4, the height of the downward position of the frame 3 can be adjusted at will, thereby facilitating the pressing of foam tapes of different thicknesses.
