Further, at least one second feeding movable block 4 is arranged below the first feeding movable block 2. Specifically, referring to fig. 2, in the embodiment shown in fig. 2, two sides of the first feeding movable block 2 are respectively provided with one second feeding movable block 4. Further, a rotating shaft 402 is arranged at one end of the second feeding movable block 4, and the rotating shaft 402 is respectively connected with the first feeding movable block 2 and the second feeding movable block 4; the second feeding movable block 4 can rotate around the rotating shaft 402. The positioning portion 401 is disposed at the other end of the second feeding movable block 4 relative to the rotating shaft 402. More specifically, the positioning portion 401 may be in the shape of a ratchet with a sharp bottom and a wide top, and the top of the positioning portion is disposed on the second feeding movable block 4; the positioning portion 401 may also be a cylindrical structure with an inclined surface; as long as the structure can make the positioning portion 401 limit the tape in a single direction, the tape may be possible. Namely, the positioning part 401 keeps limiting the material belt towards the cylinder in-place limiting block 6; and the positioning part 401 can automatically release the limit of the material belt towards the direction of the air cylinder return limit block 5 without influencing the real-time position of the material belt.

Further, the material lifting block 9 is arranged between the guide rail 7 and the blanking female die 10, and the material lifting block 9 can be used as a moving bridge for connecting the inside and the outside of the stamping die. Specifically, before the material strip to be processed enters the inside of the stamping die, the lower end surface of the material strip to be processed firstly contacts with the upper end surface of the material lifting block 9, and the material lifting block 9 can further lift the material strip to be processed, so as to facilitate the execution of the subsequent stamping operation on the material strip. Further, the blanking die 10 is disposed at a side of the material lifting block 9, and the blanking punch 12 is disposed above the blanking die 10, so that when the material strip to be processed passes above the blanking die 10, the blanking punch 12 can perform a blanking operation on the material strip.
