A single roller deviation correction device during travel

Abstract

The invention discloses a single-roller rectification device during proceeding. The single-roller rectification device comprises a movable track mechanism and a film detecting mechanism, wherein connecting plates are fixedly connected to two ends of the upper surface of a lower fixed bracket of the movable track mechanism respectively, and are connected with an upper movable bracket through deflection mechanisms; guide roller brackets are fixedly connected to two ends of the upper movable bracket, and a rectification guide roller is arranged between the guide roller brackets; a pusher is mounted between the lower fixed bracket and the upper movable bracket; the film detecting mechanism comprises a fixed detection frame, guide plain shafts are mounted on the detecting fixed frame, a screw rod is arranged between the guide plain shafts, a bar-shaped support frame is fixedly connected to one end of the screw rod, two ends of the support frame are nested on the guide plain shafts, and the other end of the screw rod is connected with a synchronous motor; the guide plain shafts are further sleeved with a sliding block which is in threaded connection with the screw rod; and a detecting head is mounted on the sliding block. According to the single-roller rectification device, the film can be rectified to a suitable position precisely in a high-speed proceeding process, and is not prone to wrinkling or scrapping.

Description

technical field [0001] The invention belongs to the technical field of printing packaging and coating material processing machinery, and relates to an integrated device with a deviation-correcting structure, in particular to a deviation-correcting device adapted to high-speed movement of a material film. Background technique [0002] With the continuous development of the global economy, printing, composite flexible packaging products, and coating material products have been more and more widely used. At the same time, labor costs and raw material costs have increased, and users have also put forward higher quality requirements for the use of such equipment. Requirements, which put forward higher requirements for the equipment for processing these products. Especially higher requirements are put forward on the speed of processing equipment. Now there are 300-500m / min equipment. After the film passes through a very long drying oven, the deviation phenomenon is very serious. ...

AI Technical Summary

Problems solved by technology

[0004] 1. During the high-speed movement of the material film, the correction roller cannot correct the material to a reasonable position;

[0005] 2. During the high-speed movement of the material film, if the correction swing is too large, it is easy to cause the material film to wrinkle or form the material film to be scrapped;

[0006] 3. Most of them cannot meet the requirement that the machine speed is above 250m / min;

[0007] 4. The deviation correction accuracy is not high;

[0008] 5. Unable to meet the requirements of various flexible packaging and coating materials
