The metallized thin film slitter comprises an unwinding roller, a transition roller, a tension regulating roller, a guide roller, an energizing roller group, a cutting mechanism, a static electricity eliminating roller, a constant speed roller and a winding roller, wherein a magnetic roller is arranged between the static electricity eliminating roller and the constant speed roller, and in contact with an insulating layer of a metallized thin film strip; a thin film strip and a conducting plate are arranged above the metallized thin film strip; the lower end of the thin film strip is in contact with a conducting layer of the metallized thin film strip; the upper end of the thin film strip is electrically connected with the head end of the conducting plate; and a second grounding wire is arranged outside the conducting plate and electrically connected with the tail end of the conducting plate. In the metallized thin film slitter, the static electricity eliminating device, namely the static electricity eliminating roller, is simple in structure and low in equipment cost, and can be utilized for effectively eliminating static electricity on the metallized thin film strip; meanwhile, the conducting layer of the metallized thin film strip can be protected from damage, and the quality of a slit product can be guaranteed; and the implementation effect is good and the application value is high.

Description

technical field [0001] The invention relates to a metallized film cutting machine with a static elimination device, which belongs to the technical field of capacitors. Background technique [0002] After the metallized film is coated in the vacuum coating machine, a raw material film with a large area and volume is formed. The raw material film must be cut into several metallized film strips by a film slitting machine, and the metallized film strips are then rewound. Produced in standard compliant metallized film rolls. [0003] The metallized film slitting machine is composed of unwinding mechanism, cutting mechanism, winding mechanism and various functional rollers. Its working principle is: the raw material film released from the unwinding mechanism enters the cutting mechanism through the tension detection roller and the empowering roller, and the raw material film is cut to form several metallized film strips, and the metallized film strips are collected by the winding...

AI Technical Summary

Problems solved by technology

However, since the metal roller is only in contact with the insulating layer in the metallized film strip, and the conductive layer in the metallized film strip has no special static elimination device, some static electricity will still remain in the conductive layer in the metallized film strip.

If the metal roller with grounding wire is used to eliminate the static electricity of the conductive layer in the metallized film strip, since the conductive layer in the metallized film strip is an aluminum-plated layer or a tin-plated layer, the conductive layer in the metallized film strip is in contact with the metal roller At this time, the conductive layer in the metallized film strip rubs against the roller body of the metal roller. If the metal roller chooses a common drive roller with a lower cost, the surface roughness of the common drive roller is large, and it is easy to damage the conductive layer in the metallized film strip, resulting in Product quality declines; if a mirror roller with a very small surface roughness is used, although the conductive layer in the metallized film strip will not be scratched, the production cost of the mirror roller is very high, and its maintenance cost is high, which is not conducive to market competition
