Provided is a rotary atomization painting device that can adjust balance in a state in which a bell cup and an inner member are integrally assembled and can achieve an increase in yield and a reduction in the number of manufacturing steps. A rotary atomization painting device including a rotary atomizer head configured to rotate to atomize paint, the rotary atomizer head having: a bell cup that is formed into a bell shape to cause paint to be formed into a thin film; and an inner member that is arranged inside the bell cup and forms a paint reservoir, the inner member having a plurality of weight mounts on which weights are selectively mountable.

A sprayer includes a housing assembly, a spray nozzle assembly and a fan assembly. The housing assembly is connected to the spray nozzle assembly. The housing assembly is configured to hold liquid, and the fan assembly is configured to generate air flow. The spray nozzle assembly is configured to atomize and spray the liquid from the housing assembly, and blowout the air flow generated by the fan assembly. When the blowing is needed, the air flow generated by the fan assembly passes through the spray nozzle assembly and flows outward. When the spraying is needed, the spray nozzle assembly atomizes and sprays the liquid from the housing assembly. The sprayer is capable of blowing and spraying, which enables the spray to have an improved applicability.

A rotary atomizing coating device includes a rotary atomizing head. The rotary atomizing head includes a first bell cup, a second bell cup, and an inner member. The outer peripheral surface of the inner member is provided with paint discharge holes. The paint discharge holes communicate with a paint supply passage. The first bell cup includes a plurality of through holes. The plurality of through holes are disposed near the paint discharge holes. The plurality of through holes communicate with the second bell cup.

A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

A spray system includes a spray applicator configured to apply a fluid to a target. The spray system also includes a rotary bell cup of the spray applicator, a splash plate of the spray applicator coupled to the rotary bell cup, and a fluid tip of the spray applicator. The fluid tip is configured to output the fluid onto the rotary bell cup. The fluid tip includes a fluid tip passage extending along a longitudinal fluid tip axis of the fluid tip. The longitudinal fluid tip axis intersects with the splash plate of the spray applicator. The fluid tip also includes a fluid exit port configured to output the fluid from the fluid tip passage onto the rotary bell cup. The fluid exit port extends along a fluid exit axis disposed at an angle relative to the longitudinal fluid tip axis of the fluid tip.

A spray nozzle includes a transmission component and a fan blade assembly. The fan blade assembly is connected to the transmission component, and can rotate with respect to the transmission component to create a vacuum inside the fan blade assembly, so that the liquid to be atomized under atmospheric pressure can enter the fan blade assembly through the transmission component. The fan blade assembly can also drive the liquid in the fan blade assembly to rotate so as to atomize the liquid and eject it from the fan blade assembly. The liquid in the fan blade assembly rotates with the fan blade assembly. A sprayer includes a body and the spray nozzle.

A sprayer includes a spray nozzle, a blower and a sprayer housing. The sprayer housing is configured to contain a liquid. The spray nozzle and the sprayer housing are connected. The spray nozzle is configured to spray the liquid out from the sprayer housing. The blower is fixedly connected with the spray nozzle, and the spray nozzle is connected to the sprayer housing through the blower. The blower is rotatable with respect to the sprayer housing so as to adjust the angle of the blower with respect to the sprayer housing, thereby enabling the angle of the spray nozzle to be adjusted with respect to the sprayer housing. The angle of the spray nozzle with respect to the sprayer housing is adjustable, so the spray nozzle is capable of ejecting the liquid at different angles with respect to the sprayer housing without moving the sprayer.

To provide a production method capable of producing an antiglare film-coated substrate having excellent antiglare performance in a short time, an antiglare film-coated substrate having excellent antiglare performance, and an article provided with the substrate. A method for producing an antiglare film-coated substrate 1 comprising a substrate 3 and an antiglare film 5 formed on the substrate 3, characterized by comprising a step of preparing a coating composition comprising at least one of a silica precursor (A) and particles (C), and a liquid medium (B), wherein the liquid medium (B) contains a liquid medium (B1) having a boiling point of at most 150° C. in an amount of at least 86 mass % based on the total amount of the liquid medium (B), a step of electrically charging and spraying the coating composition by using an electrostatic coating apparatus having an electrostatic coating gun having a rotary atomizing head, to apply it on the substrate 3 to form a coating film, and a step of firing the coating film to form an antiglare film 5.

A bell cup multi-tool and method is provided for ergonomic straight-line force applications. The multi-tool includes a manipulator for providing the straight-line pressure to a distributor in a bell cup for installation or removal. The multi-tool also includes a base for securing the bell cup in a desired orientation.

The coating machine is provided with an air motor (3), a rotational shaft (4) that is rotatably supported by the air motor (3), a feed tube (5) that extends to a tip end of the rotational shaft (4) through the inside of the rotational shaft (4), a rotary atomizing head (6) that is mounted to the tip end of the rotational shaft (4), and a shaping air ring (7) that surrounds an outer periphery of the rotary atomizing head (6) and an axial tip end of which is arranged in back of a paint releasing edge (6D) of the rotary atomizing head (6).
