Description

Technical Field

[0001] The utility model relates to the technical field of paper core slitting machines, in particular to an automatic deviation correcting device of a paper core slitting machine. Background Art

[0002] As the name suggests, paper core tubes are made of paper. Usually, they are: core rolling materials such as toilet paper core, transparent adhesive sealing paper core, tin foil plastic wrap paper core; packaging paper tube paper cans such as tea cans, perfume cans, potato chip cans, and round outer packaging of some food products; protective paper packaging such as calligraphy and painting paper tubes, LED lamp paper tubes, and chemical raw material paper tubes.

[0003] During the production of paper core tubes, a longer paper core tube needs to be cut into the required size. A slitting machine is usually used for cutting the paper core tube. When the longer paper core tube is cut to the end, the paper core tube becomes shorter and the paper core tube needs to be fixed, which makes it difficult for the cutting knife to cut the shorter paper core tube according to the required size. If the paper core tube is not fixed, the shorter paper core tube is moved to a place where the cutting knife can cut. During cutting, the paper core tube is easy to deviate with the rotation of the cutting knife. If the paper core tube is fixed, it is not easy to cut according to the required size, which easily causes certain waste. Utility Model Content
