The method for cutting with fixed length in the prior art comprises the following steps: the aluminum belt is tiled on a conveying belt which moves at a constant speed, the conveying belt drives the aluminum belt to move at the constant speed in the horizontal direction, and a cutting knife (located in a plate shearing machine) located above the aluminum belt is used for cutting the aluminum belt (perpendicular to the axial direction of the aluminum belt) at a specified time interval, so that the track is cut into thin aluminum plates with equal length (thin aluminum plates with set length are obtained). Cutter unit in the plate shearing machine among the prior art includes cutting knife and the cutting bed of setting on the conveyer belt, and cutting bed and cutting knife cooperation are cut off the aluminium strip. However, in the cutting process, because the aluminum strip is located on the upper surface of the cutting table, the cutting table can support the aluminum strip to a certain extent, and in addition, the toughness of the aluminum strip is strong, and the cutting assembly of the plate shearing machine in the prior art cannot effectively cut the aluminum strip. In addition, the cutting line (consisting of a plate shearing machine and a conveying belt) is often connected with an upstream flattening line (used for flattening the aluminum strip), and the aluminum strip conveyed by the flattening line directly enters the cutting line for fixed-length cutting. If the flattening production line breaks down or the pressure applied to the aluminum plate is too large, resistance is often generated on the movement of the aluminum strip, the movement of the aluminum strip along the transmission direction is blocked, the actual movement speed of the aluminum strip is smaller than the movement speed of the transmission line on the cutting production line (the set speed of the movement of the aluminum strip), and then the length of the cut thin aluminum plate is smaller than the set value. There is a need for a structure or apparatus that reduces the impact of upstream lines on the cutting line.

SUMMERY OF THE UTILITY MODEL
