Film roller for metallized film slitter

Abstract

A film roller for metallized film slitter relates to the technical field of machining equipment for capacitor materials and comprises a metal roller body; a central rotary shaft is arranged in the metal roller body; a roller sleeve is sleeved outside the metal roller body; mutually connected diamond-shaped lines are printed at the surface of the roller sleeve; the diamond-shaped lines are fully distributed on the circumferential surface of the whole roller sleeve; diamond-shaped areas in the diamond-shaped lines are upwards convex. Due to the special design on the roller film, the friction force generated when the roller film is contacted with the film is increased, the film can be better driven to move, no static is generated basically, the slitting quality of the film is improved and the generation of wrinkles is reduced.

Description

technical field

[0001] The invention relates to the technical field of capacitor material processing equipment, in particular to a metallized film slitting machine film roll for capacitors. Background technique

[0002] Film capacitor is a capacitor with superior performance, which has the following main characteristics: non-polarity, high insulation resistance, excellent frequency characteristics, small dielectric loss, and small volume and large capacity. Therefore, film capacitors have a wide range of uses and can form different series of products, such as high specific energy storage capacitors, anti-electromagnetic interference capacitors, anti-radiation capacitors, safety film capacitors, long-life capacitors, high-reliability capacitors, and high-voltage full-film capacitors Wait. With the development of digital, high-frequency, multi-functional, and thin, light, small, and portable electronic machines, capacitors will inevitably develop in the direction of small siz...
