When the device is in operation, the movable knife rest 30 reciprocates up and down to combine or separate the movable knife 32 with the fixed knife 22. When the movable knife rest 30 moves downwards to enable the movable knife 32 to be combined with the fixed knife 22, the movable knife 32 is matched with the fixed knife 22 to cut off the material, and one-time cutting is completed. After one shearing is finished, the movable cutter frame 30 is lifted upwards, the movable cutter 32 is separated from the fixed cutter 22 so as to carry out the next shearing, and in some technical schemes, the movable cutter frame 30 is driven by a hydraulic oil cylinder to realize the up-and-down reciprocating motion. The above actions are repeatedly executed in this way, so that the materials can be continuously processed. It should be understood that the movable blade 32 and the stationary blade 22 should have cutting edges with shapes and positions adapted to each other so as to be smoothly combined.

With further reference to fig. 3, the first column structure 11 is provided with a first guide rail 15 slidably engaged with the movable knife holder 31; the second column structure 12 is provided with a second guide rail 16 in sliding fit with the movable knife holder 31; the first guide rail 15 is located ahead of the second guide rail 16 in the feeding direction S. The movable knife 32 is arranged along a direction from the first guide rail 15 to the second guide rail 16, and when the movable knife 32 is obliquely arranged in a horizontal plane, that is, when the arrangement direction of the movable knife 32 forms an acute angle with the feeding direction S, the first guide rail 15 and the second guide rail 16 form a tandem positional relationship.

Referring to fig. 3, an inner side of the gantry 10 is located between the first inner side surface 13 and the second side surface 14, and an outer side of the gantry 10 is located outside the first inner side surface 13 and the second side surface 14, wherein the outer side of the gantry 10 includes a left outer side of the gantry 10 and a right outer side of the gantry 10.
