Description

Technical Field

[0001] The utility model relates to the technical field of uncoilers, and particularly relates to a pneumatic expansion and contraction scroll shaft device for the taper head of an uncoiler. Background Art

[0002] The main equipment of an aluminum foil slitter includes an uncoiler, an intermediate guide roller, a driving roller, a knife shaft, and a double coiler. The large coil is slit into small aluminum foil coils with equal or unequal widths by the aluminum foil slitter. The aluminum foil slitter uses a double taper head uncoiler. The aluminum foil large coil with a steel sleeve is transported to the position of the uncoiler by an upper coil car, and is automatically centered and leveled. Then, the two taper heads move towards each other to clamp the coil. Conversely, the two taper heads on the uncoiler move away from each other to loosen, and the coil or the steel sleeve is removed. Among them, on the uncoiling side of the aluminum foil slitter, pinhole detectors are respectively installed on the coiling sides of the two coilers to online detect the quality defects on the surface of the aluminum foil. According to the data results detected by the pinhole detectors, the defective parts on the edge are cut off and changed into narrow-width coils, so as to improve the product yield and reduce the scrap rate.

[0003] After the pinhole detector has been used for detection for a period of time, it is necessary to check the surface of the aluminum foil again through the pinhole detector, and the defect data results of the two detections are compared to prevent the surface defects of the aluminum foil from not being detected, which affects the production quality of the aluminum foil coil. The existing technology usually takes the small aluminum foil coil after slitting off the coiler, and then places it on the uncoiler of other aluminum foil slitters to re-uncoil and detect the defects on the surface of the aluminum foil. The operation is troublesome, and there is a problem of inconvenient detection of the surface quality defects of the slit aluminum foil. Moreover, the efficiency of detecting the surface quality of the aluminum foil is low. At the same time, the aluminum foil slitter for detecting the surface quality defects of the aluminum foil again cannot slit the large aluminum foil coil, which affects the production efficiency of the aluminum foil. Summary of the Invention
