Description
Technical Field
The utility model mainly relates to a technical field of pay-off structure, concretely relates to accurate steady pay-off structure.
Background
The accurate steady pay-off structure principle effect: the package printing material is sleeved on the discharging shaft and is transmitted by the rotation of the feeding roller and the intermittent traction roller through the corrector, so that the printing material is conveyed to the printing group for printing. In the process of printing material conveying, the existing method is as follows: firstly, the feeding shaft mechanically and manually adjusts the tightness of the printing material; secondly, the feeding roller is driven by a common variable frequency motor; the single tension roller coordinates the tension of forward pulling or backward pulling; and the tension roller only has a tension spring.
The disadvantages of such a feeding structure are: firstly, the tension of a discharging shaft is manually and mechanically fixed and adjusted, the same tension of a printing material from a large roll to a small roll cannot be guaranteed, so that the printing material is too tight to cause stretching deformation, the printing material is too loose to cause left-right swinging, the measurement accuracy of a correction sensor cannot be guaranteed, secondly, a common variable frequency motor is adopted by a material conveying roller, and the rotation accuracy is not high. The start and stop reactions are slow and have an impact on the printing material transport process. And thirdly, the single tension roller coordinates the forward pulling and backward pulling tension, so that the swing range of the tension roller is large, the tension force is large and small, and the printing effect is influenced. And fourthly, only a tension spring which is pulled downwards is provided, the tension roller moves upwards to be tightened because the tension of the tension spring is large, and the printing material which is printed downwards by the tension roller is loosened because the tension of the tension spring is small, so that the material feeding instability of the printing material is caused.
