Description

Double-pressure roller paper tape stabilizing and winding device

Technical Field

The utility model belongs to automatic industrial equipment, concretely relates to coiling mechanism is stabilized to two compression roller paper tapes.

Background

The paper tape is a flexible material, and the hardness of the paper tape is very low no matter which material is used, so that the paper tape can be greatly deformed by slight force at any point, the strength of the paper tape is not high, and the shearing force which can be borne by the paper tape is very small.

In some cases where high precision is required, particularly in laser punches, the size and spacing of the holes are subject to tight tolerances, sometimes even only a few tens of microns in diameter. Such high precision holes can easily result in the size and spacing of the holes being punched out to outside tolerances if the tape is not uniformly stressed.

On the current perforating machine tool, a tension control device is generally arranged on a paper tape to ensure the constant force of the paper tape during perforating, but the problem still occurs during winding. The paper tape is accomodate with the mode of rolling up at present nothing exception, and the back is accomplished in punching at a paper tape promptly, all can roll up the paper roll to a new book and form the scroll, saves the volume, and does not have the dog-ear, and the mechanical conditions is stable. However, due to the flexible nature of the paper tape, the instantaneous force applied should be tangential when the tape is wound onto a reel. Ideally, the direction of this force should be constant so that the wound roll is tight and undamaged. However, in the punching machine, there are necessarily unfettered forces such as friction and air flow, and particularly, the air flow moves irregularly. These factors, together with the flexibility of the paper tape, make it impossible to stably wind the paper tape as steel, and the winding process is necessarily accompanied by irregular vibrations, which, even if very small, may in some cases cause the holes already machined in the paper tape to be subjected to varying torques or shear forces, and in high precision machining, the precision of these holes is often destroyed, and in extreme cases, the paper tape is destroyed. In addition, the winding of the paper tape can generate uneven gaps, so that the stability of the paper roll is poor, and untight paper roll is easy to scatter in the conveying and transporting process, thereby causing unnecessary troubles.

In order to ensure the processing progress and the winding stability of the whole punched paper tape, a sensor is generally used for linking a tension control device, and the tension control device is used for stabilizing the paper tape. However, the tension control device is generally installed before the paper tape punching station, the stability of the paper tape after punching is limited, and the cost is greatly increased because the tension control device is a complex integrated system and a set of tension controller is added.
