Nano carbon heating films, also called nano carbon electrothermal films, graphene electrothermal films and the like, are called heating films or electrothermal films for short, and are widely applied to multiple fields of heating, electric appliances, greenhouses and the like. The processing method is mainly characterized in that nano carbon slurry is printed on a base film in a screen printing mode to form nano carbon conducting layers which are sequentially arranged, and then flexible electrodes are respectively connected in series at two ends of each nano carbon conducting layer and then film covering is carried out to form a finished product.
The processing procedure needs to carry out continuous step-by-step transport to the base film, and overspeed device tensioner, deviation correcting device etc. are indispensable. At present, the deviation correcting device is mostly completed by adopting a deviation correcting integrated machine (also called an electronic deviation correcting machine), as shown in fig. 5 and fig. 6, the structure of the deviation correcting device roughly comprises a deviation correcting roller frame which is transversely and rotatably installed through a roller frame rotating shaft, the roller frame rotating shaft is usually eccentrically arranged, two deviation correcting rollers are rotatably installed on the deviation correcting roller frame, wherein the deviation correcting roller which is far away from the roller frame rotating shaft is usually arranged at the lagging position of material conveying; when the deviation detector detects that the base film deviates, a signal is given to the deviation correction controller, the deviation correction controller controls the deviation correction driving motor to drive the deviation correction roller frame to rotate, the swing amplitude of the deviation correction roller far away from the rotating shaft of the roller frame is large, the deviation correction roller with large swing plays a role in laterally dragging the base film, and after the deviation correction roller deviates, the base film can slide along the axial direction of the deviation correction roller under the action of tensioning force of the base film, and the deviation correction is realized until the base film is deflected.
The inventor discovers that in the process of using the prior art, the base film can return to a certain degree in the return process of the deviation rectifying roller after the base film is rectified, so that secondary deviation is formed, and the deviation rectifying integrated machine can repeat the deviation rectifying action for a plurality of times. The reason is analyzed, and mainly is that the deviation correcting roller swings around the rotating shaft of the roller frame, so that the swinging angle is large, relative movement does not exist between the roller surface and the base film in the tangential direction of the swinging route, and the base film is soft, so that the static friction force of adhesion is large, and the base film is deviated again when swinging and returning. The prior art has poor effect when used in the deviation rectification work of the base film, and the base film is easy to deform or wrinkle due to repeated deviation rectification, so that the screen printing quality is influenced.
