Description

A capacitor wrapping paper film cutting device Technical Field

The invention belongs to the field of power capacitor processing equipment, and in particular relates to a capacitor wrapping paper film cutting device.

Background Art

With the rapid development of China's UHV technology, the insulation performance of capacitors is required to be stronger and the service life is required to be longer. Power capacitors with higher high-voltage resistance are needed to meet market demand. Since only the insulating paper was wound around the outside of the capacitor core, it was changed to a combination of insulating paper and film, which was wound around the outside of the capacitor core. The original cutting circular blade, accompanied by the linear motion of the rodless cylinder, the circular blade rolls naturally and cuts the insulating paper horizontally. At present, the film is added. When cutting together, it is easy to arch the paper film upward, especially at the starting point of the knife, and the paper film cannot be cut, or even arch the film halfway through the cutting, or the tail paper film is damaged. For paper films that are not completely tightened by the tension shaft, the failure rate is higher. Even with a sharp straight blade, the cutting effect is still poor. The insulating paper is brittle and easy to cut, and the film is thick and tough, so the cutting reliability is not high. This causes frequent penetration of the paper film, wastes operation time, and affects production efficiency.

In addition, due to the large number of specifications of capacitors, the excess part of the upper edge of the insulating paper needs to be cut off, and the cutter is always exposed. Workers are prone to safety problems when stringing the paper film and cleaning, which poses a great safety hazard. Moreover, when newly installed insulating paper rolls are used, manual intervention is required to start cutting the paper, and the work is relatively cumbersome.

Specifically, the blade assembly is further divided into a motor and reduction box assembly 303, an elastic coupling 304, a seated double bearing assembly 305 and a rotating blade shaft assembly 306. The motor drives the reduction box, which in turn drives the seated double bearing assembly 305 and the second blade 308 to operate.

The motor and reduction box assembly 303 is composed of a motor, a reduction box, and a bracket, and is used to output rotational power. The motor uses a DC motor with a DC 24V safety voltage, 30W, and 421 rpm. The reduction box uses a planetary gear reduction box. The motor and reduction box are combined into one, and the speed can be adjusted. The bracket uses an angle iron bracket, which is connected to the motor and reduction box assembly 303 on one side and fixed on the connecting plate 302 on the other side.

It has eight sharp arc surfaces, and can cut paper film in a point-like manner. It has a large cutting force and is easy to cut paper film. It is more stable and reliable to cut paper film in irregular arcs at high speed. The octagonal blade runs in the forward cutting direction to cut paper film. The above-mentioned round nut 309 adopts a hexagonal nut with fine pitch thread and a small helix angle. The nut is not easy to loosen and has a large tightening torque. The spiral direction: left-handed (reverse thread), the nut and the rotating shaft run together, and the reverse force of the nut tightens the flange and the second blade 308 to prevent the nut from loosening.

The working process of this embodiment is now described: the insulating paper and film are placed at the starting end of the discharge shaft of the wrapping machine, and the driving roller rotates to drive the insulating paper and film to move in a straight line. The first blade 206 extends from the first protective cover 205 by the double-rod cylinder 202, inserts the insulating paper, and cuts the excess part of the insulating paper as the insulating paper moves in a straight line. The waste paper winding machine (not shown in the figure) rolls up the excess insulating paper. Subsequently, the paper film will enter the next step of the process along the horn guide port of the second protective cover 310. It is necessary to manually place the paper film (insulating paper and film) on the surface of the core, fix the paper film with a water-soluble tape, and set the tension by the tension shaft controller. Under the guidance of the discharge shaft of the wrapping machine, the main shaft of the wrapping machine drives the core to rotate, and the paper film is wrapped around the core. After rotating a number of circles, it stops rotating. The motor of the transverse cutting component 3 automatically starts a few seconds in advance, and the octagonal blade runs smoothly. The clamping wheel presses the paper film, and the rodless cylinder 301 rises slowly from bottom to top in a straight line, and the octagonal blade runs at high speed to cut the paper film from bottom to top. After the work is completed, the first blade 206 will automatically retract into the first protective cover 205.
