Description

Slitting Cutting Device {CUTTING DEVICE OF SLITTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for slitter, and more particularly, to a cutting device for cutting a film or metal material for producing a capacitor at equal intervals.

As is generally known, a capacitor is a dielectric material sandwiched between electrodes and wound with a roll. The capacitor is divided into a film capacitor, an electrolytic capacitor, an oil capacitor, and a tantalum capacitor according to the material and insulating material of the dielectric. The film capacitor is excellent in low frequency and high frequency characteristics and is large in size and expensive. The electrolytic capacitor can be used for smoothing power supply because it can make high capacity at low cost. The tantalum capacitor is to use an anode metal as tantalum.

When manufacturing the above-mentioned capacitor, it is wound by using a polyester film, polypropylene film, aluminum foil, etc. selectively, and each film or the like maintains a thickness of 2 to 5 μm and maintains a width of 1.2 to 10 mm. To form. The thickness and width of the film can be formed differently according to the type of the condenser, and the cutting (cutting) of the film is usually made through a cutting device of a slitter provided with a ring knife.

In the conventional slitter cutting apparatus, as shown in FIGS. 1 to 5, the raw material F is rotated in proportion to the rotational speed of the feed roller 1 and the feed roller 1 to which the raw material F is fitted. Guide roller (2) for guiding in one direction, a top roller (3) to which the ring knife (4) is coupled to cut while rotating the raw material (F) supplied by the guide roller (2), The lower roller 5 with the knife guider 6 coupled thereto so that the ring knife 4 of the upper roller 3 can be inserted therein, and the raw material F passing through the lower roller 5 with the product rollers on both sides ( 8, 8 ') is composed of a separation roller (7) installed to be supplied to.

The feed roller 1, the guide roller 2, and each of the rollers 3, 5, 7 guide the positional movement of the raw material F, and each of the rollers 1, 2, 3, 5, 7 ,) Is powered by a control signal of a controller (not shown) and rotated with a specific rotational force.
