A rotary atomization head is provided, which prevents discharged threads of a coating material from making contact with each other and from being unified. A rotary headincludes: a diffusion surfaceto diffuse the coating material toward an outer edge partby centrifugal force; and a plurality of groovesformed on the outer edge part. The plurality of groovesextends in a radial direction. The adjacent grooveshave different depths. The grooveshave the same width.

Rotary atomization head and coating device

A coating device is equipped with a rotary head, a drive unit, and an electric power supply unit. The rotary head is configured to be supplied with a coating material. The rotary head includes a diffusion surface that is configured such that the coating material is diffused toward an outer edge portion of the diffusion surface by a centrifugal force, and a plurality of groove portions that are included in the outer edge portion. The rotary head is configured to discharge a threadlike coating material from the groove portions. Also, the coating device is configured such that a diameter of the threadlike coating material is set equal to or larger than 0.03 mm and equal to or smaller than 0.1 mm and that the threadlike coating material is electrostatically atomized.

Coating device

A hopper for cleaning a coating machine in which a rotary atomizing head extends through an opening in the upper surface of a hopper housing, a thinner for cleaning the rotary atomizing coating machine and a residual coating material are sprayed on the inside, an airstream control member for preventing flow from ascending from the inside of the housing to the outside of the housing through a gap between the coating machine and the opening by the rotation of the rotary atomizing head corresponding to the gap between the coating machine and the opening, and the control member is formed with an air vent hole for supplying air to a negative pressure zone formed just below the rotary atomizing head.

Hopper for cleaning coating machine

A coating machine having a coating material discharging mechanism for discharging a previously filled coating material under pressure to an atomizing mechanism wherein a coating material bag for filling a coating material is housed in a coating material discharging chamber of a predetermined volume and an inlet/exit port of an operating fluid is disposed for exerting a pressure from the outside of the coating material bag thereby discharging the coating material under pressure, while crushing the coating material bag, whereby paint or other coating material can be discharged under pressure reliably by a small driving force.

Coating machine

A small-sized and inexpensive coating material feeding apparatus capable of feeding even a coating material comprising less miscible main agent and curing agent as in an aqueous two component mixed coating material, while uniformly mixing them, to a coating machine or a coating material tank under extremely simple control, the apparatus comprising a measuring unit having a measuring cylinder for delivering the coating material ingredients each by an amount in accordance with the mixing ratio individually and simultaneously to the coating material tank, a storage unit having a transfer cylinder for storing the coating material prepared by mixing each of the coating material ingredients previously and then delivering the same to the coating machine or the coating material tank, and a valve unit formed with a switching valve for conducting channel switching, in which the coating material ingredients delivered from the measuring cylinder are pre-mixed in the channel stirring pre-mixer and a coating material delivered from the transfer cylinder is uniformly diffused and mixed in a jetting diffusion mixer.
