Description

technical field [0001] The invention relates to the technical field of slitting a coiled sheet, in particular to a precision automatic longitudinal slitting device. Background technique [0002] The slitting equipment for processing coiled sheets is divided into transverse shearing machine and slitting machine, among which the slitting machine is the most widely used. The slitting machine is also called a slitting unit or a slitting line. Then the blades in the slitting machine are cut into strips of the width required by customers, and finally the strips are rolled into small rolls for the next process. Small rolls can also be used by manufacturers of transformers, motors, and auto parts. . The thickness of the raw material is generally 0.6mm~5mm, and the material of the metal coil is generally cold-rolled, hot-rolled carbon steel, silicon steel, stainless steel, galvanized and other metal materials. [0003] The current longitudinal slitting machine mainly includes a hyd...

Problems solved by technology

[0004] However, as the production progresses, the degree of tightness between the layers of the coiled sheet on the uncoiler is different. In some places, the layer is very tight, while in some places it is very loose, resulting in the coiled sheet fed into the slitting machine The instantaneous speed changes greatly, and the instantaneous speed exceeds the normal range, which eventually leads to burrs on the coiled sheet after slitting, and the strip width exceeds the error range, which cannot meet the customer's requirements. The instantaneous speed of the coiled board inside changes greatly, and the instantaneous speed exceeds the normal range, which seriously affects the flatness of the product

Therefore, in order to solve this situation, workers need to control the rotation speed of the uncoiler from time to time to make the motor accelerate or decelerate, which obviously increases the labor intensity, and the production output is very low, and the products are difficult to meet the large market demand.
