Abstract
The utility model belongs to the field of thin-film capacitor coilers, and particularly relates to a dynamic tension control device of a coiler. The dynamic tension control device of the coiler comprises a PLC, signal input equipment and an electric proportional valve, wherein the signal input equipment and the electric proportional valve are connected with the PLC, the electric proportional valve is connected with an air cylinder, the air cylinder is connected with a tension mechanism, the signal input equipment sets initial tension, coiling acceleration and a coiling initial speed and then transmits the setting signals to the PLC, the PLC works out the needed tension, converts the tension into analog signals and outputs the analog signals to the electric proportional valve, and the electric proportional valve converts the analog signals of the tension into air pressure to control the tension mechanism to provide tension. The dynamic tension control device of the coiler has the advantages of being capable of timely adjusting the tension generated by the frictional force of a guide wheel on a thin film, and improving the reliability of products.
Description
Technical field
The utility model belongs to thin-film capacitor winding machine field, specifically a kind of dynamic tension control setup of up-coiler.
Background technology
Up-coiler constant pressure coiling when carrying out winding film can cause electric capacity tight inside but loose outside, every circle film is the internally certain contraction of circle formation all, therefore the convergent force that outer ring is subject to is less than inner ring, thereby form tight inside but loose outside, and on plug the similar rubber plate that wraps up on iron pipe of coiled film, the larger hardness of diameter is lower, when thermal finalization, the power that inside contracts that inner ring is received can be greater than the convergent force that outer ring is subject to, and further aggravates this phenomenon.Outside, due to the pine of reeling, easily causes loss excessive, and capacity attenuation, near plug place coiling tension, easily causes film local damage.Meanwhile, because the tension force compositing factor of thin-film capacitor upper film is a lot, except swing arm exert oneself and the control of tension motor, guide wheel is also one of larger factor to the effect of film.When accelerating, guide wheel makes memberane stress become large to the friction wheel of film; When slowing down, guide wheel diminishes tension force to the friction force of film, has further aggravated phenomenon tight inside but loose outside.
Summary of the invention
How problem to be solved in the utility model makes film uniform tension in order in winding process better, and a kind of dynamic tension control setup of up-coiler is provided.
The utility model provides following technical scheme:
The dynamic tension control setup of up-coiler, it comprises PLC controller and the signal input device being connected with PLC controller, electric Proportion valve, electric Proportion valve is connected with cylinder, cylinder is connected with tension mechanism, signal input device passes to PLC controller setting signal after setting initial tension, coiling acceleration/accel and coiling rate of onset, PLC controller converts analog signal output to electric Proportion valve after calculating needed tension force, and electric Proportion valve converts the analog signal of tension force to air pressure size control tension mechanism tension force is provided.
Described tension mechanism comprises swing arm, tension arm and mistake roller, and tension arm is connected with swing arm, crosses roller and is located at tension arm end.
Described signal input device is touch-screen.
The utility model has the advantages that the tension force that energy timely adjustment guide wheel produces the friction force of film, the reliability of improving product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is mechanical mechanism schematic diagram.
The specific embodiment
As Fig. 1, shown in Fig. 2, the dynamic tension control setup of up-coiler, it comprises PLC controller and the signal input device being connected with PLC controller, electric Proportion valve, electric Proportion valve is connected with cylinder 1, cylinder is connected with tension mechanism, signal input device is set initial tension, after coiling acceleration/accel and coiling rate of onset, setting signal is passed to PLC controller, PLC controller converts analog signal output to electric Proportion valve after calculating needed tension force, electric Proportion valve converts the analog signal of tension force to air pressure size control tension mechanism tension force is provided, tension mechanism comprises swing arm 2, tension arm 3 and excessively roller 4, tension arm 3 is connected with swing arm 2, cross roller 4 and be located at tension arm 3 ends, generally, signal input device is touch-screen.
Unreel 7 pairs of films and carry out anti-rollly after crossing roller 5,4,6, to rolling 8, carrying out rolling successively, when accelerating rolling, 1 action of PLC controller control cylinder, makes swing arm reduce certain tension force and offsets the tension force of part guide wheel to the friction force generation of film; When slowing down, swing arm increases certain tension force and offsets the tension force that part guide wheel produces the friction force of film.
