In general, the length of the moving blade and the fixed blade cover the width of the strip. In the existing production process, when strip wires with the length of 300mm or less are produced, the straightness tolerance of the cutting edges of the movable cutter and the fixed cutter can be controlled within 0.01mm, but when the length exceeds 300mm, for example: when producing strip silk of 1000mm length, the straightness accuracy tolerance of moving sword and stationary knife blade will be more than 0.2mm, can't satisfy the requirement that the interval between moving sword blade and the stationary knife blade is 0.02 mm.

However, the width of the strip coil processed by the prior art is too wide and is 800-1000mm, if the strip coil is directly transversely cut into strip threads, larger-width shredding equipment is needed, and the shredding equipment is not available in domestic and international markets at present, because the requirements of the large-width shredding equipment on the materials, the processing precision and the assembly of parts and production workshops are extremely high, the processing difficulty is higher, even if the strip threads with too large lengths are barely processed, the strip threads still need to be cut into short cut tobacco threads meeting the length requirements of cigarettes, the investment and the processing procedures are increased, the rejection rate of the subsequent cigarette production is increased, the quality of the cigarettes is influenced, the cost is increased, and the resource is wasted, so that the prior art is not preferable.
