Problems solved by technology
However, the structure of the previous proposal is too complicated, because the elastic strain and mechanical loss of the wire itself when there are multiple sets of pulleys, the influence of the rotational moment of inertia of the pulleys is more complicated than that of the film itself, and the previous proposal uses the reaction force to offset the tension of the swing wheel set. Shaking, if the material of the material is changed, or the operating conditions of the machine are different, errors will occur, and it must be re-calibrated
This reduces the processing efficiency of thin film materials

Embodiment Construction
[0034] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0035] see Figure 1A , Figure 1B and Figure 1C , which is a schematic diagram of the operation of a conveying device for film materials (such as a screen printing conveying device for roll-to-roll process). Also see figure 2 , which is a schematic diagram of the steps of the active tension control method; as shown in the figure, the active tension control method of the present invention is used in a conveying device 100 of the film material 10 . The conveying device 100 of the film material 10 is applied in an intermittent continuous feeding process (that is, the continuous film material is fed intermittently), such as the conveying device 100 of the film material 10 can be a screen printing conveying device for a roll-to-roll p...

The invention relates to an active tension control method, which is to control the torque of the tension swing wheel set to control the tension sensing wheel to measure the tension of the film material close to a tension set value, and then adjust the tension swing wheel set The speed and torque of the tension swing wheel set are close to half of the linear speed of the feeding wheel, and the tension of the film material measured by the tension sensing wheel is still close to the tension setting value, and then repeated Unwinding and feeding of the film material. The active tension control method of the present invention can solve the non-uniform tension phenomenon caused by the stop-and-go continuous intermittent movement of the discharge wheel, the tension swing wheel set and the feed wheel.
Description
technical field [0001] The invention relates to a tension control method, in particular to an active tension control method, which can solve the uneven tension phenomenon caused by the stop-and-go of the feeding wheel, the tension swing wheel set and the feeding wheel. Background technique [0002] The film is a film material, so when the film roll-to-roll process is processed, the film material is mostly conveyed to a feed wheel by a discharge wheel, and there is a tension swinging wheel set between the discharge wheel and the feed wheel. The film maintains a certain tension during conveying and processing. However, in the roll-to-roll process of film materials, such as continuous but intermittent transmission similar to screen printing, the frequent start and stop of the feed wheel often causes inertia between the feed wheel and the tension swing wheel set. And cause sloshing, which in turn affects the phenomenon of unstable tension of the film material, and finally affec...
