[0106] Rotate the guide rod 42. The guide rod 42 drives the spring baffle 441 to move relatively or towards each other through screw transmission, so as to drive the sliding sleeve 41 to move through the first spring 43, and further adjust the clamping position and clamping angle of the clamp 11 on the material.

[0107] In the slicing mechanism 5, the moving frame 10 drives the end seat 51, and the end seat 51 drives the cutter 54 to slice the material. At the same time, the second spring 53 elastically limits the cutter 54 to avoid rigid collision between the cutter and the material and damage to the cutting edge.

[0108] In the exhaust mechanism 6, the moving frame 10 drives the fixed rod 61 to push the piston 62. The piston 62 slides in the air cylinder 63. At this time, the air pressure in the air cylinder 63 increases. When the air pressure increases to a certain value, the one-way air outlet valve 13 conducts; at the same time, when the moving frame 10 moves downward, the rack 646 drives the gear 645 to rotate. At this time, the elastic torsion spring 644 is stressed and contracts. After that, the rack 646 and the gear 645 are disengaged. Under the elastic force of the elastic torsion spring 644, the gear 645 drives the connecting cylinder 642 to rotate reciprocally. The connecting cylinder 642 drives the exhaust pipe 643 to swing reciprocally, and the exhaust pipe 643 blows and removes impurities from the material.

[0109] In the pre-positioning mechanism 7, the outer sleeve 71 is communicated with the connecting cylinder 64. The push rod 72 is slidably and sealingly connected with the outer sleeve 71. The positioning plate 73 is fixedly connected with the push rod 72; when the piston 62 moves downward along the air cylinder 63, the air pressure in the air cylinder 63 increases. At this time, under the push of the air pressure, the push rod 72 slides in the outer sleeve 71, and the push rod 72 drives the positioning plate 73 to clamp and position the material.

[0110] The positioning plate 73 is provided with a plurality of air holes 15. The middle of the push rod 72 is penetrated, and the push rod 72 is provided with a one-way air inlet valve 14; when the moving frame 10 drives the fixed rod 61 to move upward, the fixed rod 61 drives the piston 62 to move upward in the air cylinder 63. At this time, the air pressure in the air cylinder 63 decreases. Under the action of the air pressure, the one-way air inlet valve 14 conducts, and the fine chips and impurities around the material are sucked into the air cylinder 63.

[0111] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0112] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
