Abstract
The utility model discloses a longitudinal deviation correction device of an unwinding mechanism of a printing machine, which is arranged on the unwinding mechanism of the printing machine. The unwinding mechanism consists of a fixed base, a movable base, a frame, an unwinding roller, an unwinding roller bracket and a paper guide roller, wherein the middle of the movable base is fixedly provided with a longitudinal thruster; the front end of the thruster butts against the middle part of a push rod; the thruster is connected with an electric control box; the electric control box is connected with and controls an inductive head; and the inductive head is arranged at one side of the paper guide roller at the side surface of the frame and used for detecting the longitudinal deviation signal of the paper on the paper guide roller. When in working, the inductive head detects the longitudinal position deviation signal of the paper roll on the paper guide roller, and the signal is processed by an automatic control system in the electric control box after being transmitted to the electric control box, and then the automatic control system timely controls the thruster to push forward or pull backward so as to calibrate the longitudinal position of the movable base and realize timely control for longitudinal deviation of the unwinding device.
Description
Technical field
The utility model belongs to the printing machinery technical field, relates to the vertical deviation correcting device of a kind of printing machine unreeling structure.
Background technology
In the prior art, the printing machine unreeling structure is made up of firm banking, mobile base, frame, let off roll, let off roll support and dancing roll, mobile base is installed on the firm banking by slip locating shaft and slideway, frame is installed on the mobile base, frame one side is equipped with dancing roll, the coil paper support is installed with a rotating shaft in the frame upper end, one end of coil paper support is equipped with let off roll, coil paper is installed on the let off roll, on mobile base, the front end of coil paper support is equipped with a paper guiding roll to the coil paper support with a cylinder supports.This unwinding device after printed web is installed on the let off roll, is suitably adjusted the mode that the lengthwise position deviation of coil paper can adopt people's formula to regulate in use, and the precision of adjustment is lower and require great effort time-consuming.
Technical scheme
For solving problems of the prior art, improve the centering capacity of coil paper lengthwise position deviation in the printing equipment unwinding device, realize the real-time adjustment of coil paper along track bias in the production process, the utility model provides a kind of printing machine unreeling structure vertical deviation correcting device, in the process of unreeling, lengthwise position to band pull coil paper detects in real time, and instant correction.
The technical scheme that realizes the present utility model purpose is: at longitudinal thrust device of the middle part of mobile base fixed installation, the thruster front end withstands on a horizontal push rod middle part, the two ends of push rod are fixed on the firm banking with fixed leg, thruster is connected on the electric cabinet, connect on the electric cabinet and control an inductive head is arranged, inductive head is installed in dancing roll one side of frame side, detects vertical offset signal of paper on the dancing roll.Inductive head can be a spot type inductive head, can use a servomotor on the thruster, and electric cabinet is connected with servomotor, controls the working condition of thruster by the control servomotor.
When this device work, inductive head detects the lengthwise position deviation signal of coil paper on the dancing roll in real time, detected signal is after passing to electric cabinet, handle by the robot control system(RCS) in the electric cabinet, robot control system(RCS) is controlled immediately and is pushed away or post-tensioning before thruster carries out afterwards, the lengthwise position of calibration activities base, thus the calibration coil paper vertically unreel the position, realize instant control to the unwinding device along track bias.
