Photoelectric corrective mechanism adopting rust-proof electric cylinder for coil slitting machine

Abstract

The invention discloses a photoelectric corrective mechanism adopting a rust-proof electric cylinder for a coil slitting machine. The photoelectric corrective mechanism comprises an unreeling roller, a support, guide tracks, a photoelectric sensor, the electric cylinder and a controller, wherein the electric cylinder comprises a corrugated expansion pipe connecting a bearing pipe and a thread bushing; and the photoelectric sensor comprises a cover plate, tubular supporting columns and screws arranged inside the tubular supporting columns. According to the photoelectric corrective mechanism, the deviation conditions of edges of coils can be detected constantly through the photoelectric sensor, the correction is carried out in time, the correction accuracy is high, and the working efficiency of the correction is high; screw rods are sealed through the corrugated expansion pipe, so that water is prevented from contacting the screw rods and causing corrosion and damage of the screw rods, and the failure rate of a correction device is decreased; the photoelectric sensor supports the cover plate through the tubular supporting columns, during installation, both the cover plate and a circuit board share the same connecting screws, the number of the screws is small, and the working efficiency for installation is high; and the sealing cover plate is fixed on the tubular supporting columns through screws, during manufacturing, threaded holes are not required to be formed in the U-shaped casing, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a deviation correcting device, in particular to a deviation correcting device for a coil slitting machine. Background technique [0002] Coil slitters, such as roll paper slitters, are prone to the problem of roll paper offset during the slitting process. In the prior art, when the roll paper is offset, the lateral movement of the unwinding device is manually adjusted to correct the roll paper offset problem. However, manual deviation correction cannot detect the problem of coil deviation in time, and the manual adjustment of the unwinding device's lateral movement, the deviation correction accuracy is low, and the deviation correction work efficiency is poor. Contents of the invention [0003] In view of this, the object of the present invention is to provide a photoelectric correction mechanism for a coil slitting machine using an anti-rust electric cylinder, to solve the problem that the coil deviation cannot be found in ...
