The nut seat 213 is fixedly connected with the feeding support 221 , and the feeding support 221 can move synchronously with the nut seat 213 . When the feeding motor 211 rotates forward, the nut seat 213 and the feeding support 221 move from the retracted position to the slitting position, and the material is pushed toward the slitting assembly 300 . When the feeding motor 211 is reversed, the nut seat 213 and the feeding support 221 move from the slitting position to the retreating position. At this time, the material remains at the current position until the next time the feeding motor 211 rotates forward, the material is pushed forward. Compared with pushing the material through multiple intermittent one-way movements, the reciprocating motion for pushing the material can reduce the moving stroke of the feeding drive, save the required space, and make the entire structure more compact, which is conducive to the miniaturization of the device.

In some embodiments, a first sliding rail 272 is fixedly connected to the bottom plate 223 of the feeding assembly, a first sliding block 271 is fixedly connected to the feeding support 221, and the first sliding block 271 cooperates with the first sliding rail 272.

In this way, when the material is pushed, the material pushing member 240 is in elastic contact with the material, which can prevent the material from being damaged compared with the rigid contact. Specifically, the pressing portion at the free end of the pushing member 240 for pressing the material can be connected with the main body of the pushing member 240 through a spring. Alternatively, the pressing portion at the free end of the pushing member 240 for pressing the material can be selected from an elastic material.

Generally, the electrostatic brush includes a whole piece of release paper 610 , on the whole piece of release paper 610 are arranged multiple rows of double-sided tapes 620 arranged at intervals and extending longitudinally, and pasted on the top of the double-sided tapes 620 with multiple rows of spaced arrangements And the laterally extending bristles 630 are distributed with multiple rows of longitudinally extending aluminum foil tapes 640 above the bristles 630 , and the positions of the aluminum foil tapes 640 correspond to the positions of the double-sided tapes 620 . When pushing the material, the bottom end of the pushing member 240 abuts against the edge of the aluminum foil tape 640, so as to push the whole piece of release paper 610 forward. Before cutting, the length of each cutting and the number of cuttings are calculated and input to the display screen 520 . After all the bristles 630 on a whole piece of release paper 610 are cut, the length of the bristles that fall at the last section may be different from the lengths that fell before, so it needs to be picked out manually and placed separately. After all the bristles 630 on each release paper are cut, the device will automatically turn off. After placing the next release paper in a predetermined position, press the switch 530 again to turn on the device. When placing the release paper, move it to the position where the pusher 240 can abut against the raised edge of the second aluminum foil tape 640 , that is, it is placed in place.

Preferably, the free end of the pushing member 240 is in a "V" shape. In this way, when the material is pushed, its free end can be stably stuck at the edge of the aluminum foil tape 640 and is not easily separated from it.

Of course, in other embodiments, the above-mentioned cutting device can also be used for cutting other materials. When the pushing member 240 pushes the material, components such as a suction cup may be arranged at the bottom end of the pushing member 240 to adsorb and fix the material and push it forward.
