Shearing is required in the production process of automobile decorative strips, so shearing equipment for automobile decorative strip production is required. Among them, the "a cutting device for the production of plastic decorative strips" disclosed in the application number "CN210850463U" has solved the problem that when cutting plastic decorative strips, the traditional method is that the operator holds the plastic strip and puts it on the cutting machine for cutting, which greatly increases the danger of the operator, and the stability is high during cutting. The cutting accuracy is not good, and there are many disadvantages of cutting errors. However, in actual use, there are still many defects in the shearing equipment for the production of automobile decorative strips with similar structures, such as: it does not have the function of measuring the cutting length of automobile decorative strips, resulting in the inability to accurately cut the automobile decorative strips during shearing, reducing the uniformity of the cutting length of the automobile decorative strips and increasing the defective rate of the cutting of the automobile decorative strips; it does not have the anti-deviation function, resulting in the position of the automobile decorative strips being easily offset during the transmission process, resulting in the tilt of the cut of the automobile decorative strips, reducing the shearing quality and increasing the defective rate of the automobile decorative strips.
