Specifically, when the reset spring 171 is configured to release the elastic force, the lifting rack 14 pushes against the material receiving plate 13 to lift it from the bottom of the punching profiling groove 12 to the notch of the punching profiling groove 12. When the buckle is configured to be engaged, the lifting rack 14 pulls the material receiving plate 13 to lift it from the notch of the punching profiling groove 12 to the bottom of the punching profiling groove 12. In addition, the lifting and lowering of the material receiving plate 13 is controlled, so that the diaphragms 611 that are stacked and stored to a certain amount are easily removed from the material receiving plate 13.

[0097] A driving shaft 163 is coaxially and synchronously connected between the active first wheel 161 and the active second wheel 162;

[0098] A handle wheel 18 is disposed adjacent to the outer side wall of the punching and cutting platform 1. The handle wheel 18 includes an integrally formed driving wheel 181 and a driving handle 182. The driving wheel 181 is coaxially and synchronously connected to the driving shaft 163.

[0099] The side wall of the punching and cutting material platform 1 is also provided with a ratchet 183 and a pawl 184, the ratchet 183 is coaxially and synchronously connected with the driving wheel 181, the pawl 184 is provided with a material picking handle 1841, a hinge pin 1842 and a tension spring 1843, the material picking handle 1841 is provided at one end of the pawl 184, one end of the tension spring 1843 is hooked at the end of the pawl 184 away from the material picking handle 1841, the hinge pin 1842 is located between the material picking handle 1841 and the tension spring 1843, and the other end of the tension spring 1843 is hooked on the punching and cutting material platform 1. Specifically, the pawl 184 is hinged to the punching and cutting material platform 1 through the hinge pin 1842, that is, the pawl 184 can rotate along the hinge pin 1842 as a rotating axis.

[0100] In another embodiment, if Fig.10As shown, a lifting plate 143 is synchronously connected between the first rack 141 and the second rack 142; the punching profiling groove 12 also includes an intermediate profiling groove 123 located between the first profiling groove 121 and the second profiling groove 122, and the receiving plate 13 also includes an intermediate receiving block 133 matched with the intermediate profiling groove 123, and a support rod 144 is connected to the bottom of the intermediate receiving block 133, and one end of the support rod 144 away from the intermediate receiving block 133 is connected to the lifting plate 143;

[0101] The elastic member 17 is a return spring 171 connected to the end of the lifting rack 14 away from the receiving plate 13 or a coil spring 172 connected to the driving shaft 163. Specifically, when the elastic member 17 is a return spring 171, as Figure 6 and Fig.10 As shown, the return spring 171 is arranged at one end of the lifting rack 14 away from the material receiving plate 13. When the lifting rack 14 descends, the return spring 171 is compressed to generate elastic force; the material taking handle 1841 on the ratchet 184 is moved to separate the ratchet 184 and the ratchet wheel 183 so that the return spring 171 releases the elastic force. When the return spring 171 releases the elastic force, it acts on the lifting rack 14 to push the lifting rack 14 to lift. When the elastic member 17 is a coil spring 172, as shown in FIG. Figure 10~Figure 12 As shown, the coil spring 172 is arranged on the driving shaft 163. When the driving wheel 16 is rotated in the positive direction to drive the lifting rack 14 to descend, the coil spring 172 generates a rewinding elastic force. The material taking handle 1841 on the ratchet 184 is moved to separate the ratchet 184 and the ratchet 183 so that the coil spring 172 releases the elastic force. When the coil spring 172 releases the elastic force, it acts on the driving wheel 16 and drives the driving wheel 16 to rotate in the opposite direction, and then drives the lifting rack 14 to rise through the driven wheel 15. Then, the lifting and lowering of the material receiving plate 13 is controlled, so that the diaphragms 611 that are stacked and stored to a certain amount are easily removed from the material receiving plate 13.
