Description

Technical Field

[0001] The utility model relates to the technical field of deviation correction devices, in particular to a deviation correction device for processing degradable films. Background Art

[0002] During the production and transportation of degradable film, if the pressure of the tensioner is insufficient or unstable, the degradable film may deviate. Vibrations such as left and right, up and down, or rotation during transportation may also cause deviation. The degradable film needs to be properly adjusted after deviation. The deviation correction device is a mechanical device that corrects the lateral error of the coil during its forward movement. The displacement correction achieves lateral correction by changing the span of the film at the inlet and outlet.

[0003] For example, a film processing device and a film offset correction device disclosed in the authorization announcement number CN215946274U, the film offset correction device can cooperate with the roller group to convey the film, and the film offset correction device includes an airflow adjustment unit for controlling the inlet and outlet of the airflow, a translation drive unit, a correction roller, a fixed roller and an offset detector. The surface of the correction roller is formed with a plurality of airflow adjustment units connected to each other so that the airflow can enter and exit the correction wheel air holes acting on the film. The fixed roller is arranged between the correction roller and the roller group, and the surface is formed with a plurality of airflow adjustment units connected to each other so that the airflow can enter and exit the fixed wheel air holes acting on the film;

[0004] Although it is realized that when the deviation detector detects that the deviation of the film is greater than the threshold, at least the correction roller among the correction roller and the fixed roller will absorb the film and translate along the axial direction of the correction roller together with the film, so that the deviation of the film after correction is not greater than the threshold. In this way, the deviation of the film can be corrected in real time when the film has an abnormal deviation;
