A device for removing static electricity from a paint-spraying rotary cup

Abstract

The invention relates to the field of paint spraying, in particular to a device for removing static electricity of a paint spraying spinning cup. The device comprises a paint spraying spinning cup component and at least one static electricity guiding component; the paint spraying spinning cup component comprises a spinning cup for spraying paint and a spinning cup molding hood; an opening is formed in one end part of the spinning cup molding hood; the spinning cup molding hood and one end part of the spinning cup are fixedly connected in a sleeving way by using the opening in one end part of the spinning cup molding hood; each static electricity guiding component comprises a conductive connecting part, a conductive spring and a conductive wire; each conductive connecting part can be in contact with the side wall of the spinning cup molding hood; one end part of each conductive spring and the corresponding conductive connecting part are fixedly connected; one end of each conductive wire is connected with the other opposite end part of the corresponding conductive spring; and when the spinning cup sprays paint, static electricity on the spinning cup molding hood is guided out through the conductive connecting parts, the conductive springs and the conductive wires in sequence.

Description

technical field [0001] The invention relates to the field of painting, in particular to a device for removing static electricity from a painting rotary cup. Background technique [0002] The application of the rotary cup in the modern automobile painting process is more and more extensive, and the high-speed rotation of the rotary cup usually accumulates thousands of volts or even tens of thousands of volts of high-voltage static electricity on the metal forming cover of the rotary cup. This high-voltage static electricity is not only to a certain extent Affects the performance of the bell and can cause major safety issues in the spray booth. For example, when high-voltage static electricity is close to the sharp corners of metal objects, it will cause tip discharge phenomenon, which can seriously cause sparks, which may detonate the paint in the spray booth, thus causing major safety problems. Contents of the invention [0003] Aiming at the problems existing in the prio...
