Automatic spraying equipment for outer surface of valve body

Abstract

The invention relates to automatic spraying equipment for the outer surface of a valve body. The automatic spraying equipment mainly solves the problems that existing automatic spraying equipment is low in product percent of pass, low in production efficiency and uneven in coating. The automatic spraying equipment is characterized in that trolleys (3) are connected to a caterpillar type conveying device (1), and a valve body locating disc (4) capable of rotating is mounted above the trolleys (3); a spraying station is arranged in a spraying chamber (2), the caterpillar type conveying device (1) drives the trolleys (3) to move and stops when the trolleys (3) arrive at the spraying station, and a first spray gun (5) capable of doing up-down reciprocating motion and a second spray gun (6) capable of doing reciprocating rotation motion are correspondingly arranged on the two sides of the spraying station. The automatic spraying equipment for the outer surface of the valve body is controlled through a PLC, spraying of various paint can be conducted automatically, the coating thickness is adjustable, the spraying accuracy rate is high, and no dead corner exists in the spraying process; and the automatic spraying equipment is suitable for valve bodies of various specifications and has the beneficial effects of being high in product percent of pass, high in production efficiency, even in coating and free of contaminating the environment.

Description

technical field [0001] The invention relates to the field of spraying on the outer surface of a valve, in particular to an automatic spraying equipment on the outer surface of a valve. Background technique [0002] The valve body is the main part of the valve. The outer surface of the valve body needs to be sprayed during the process of processing to prevent the valve body from being corroded, enhance the physical properties of the valve body, and prolong the service life of the valve body. Existing spraying equipment for the outer surface of the valve includes a spraying room and a pneumatic spraying machine. Usually, the valve body is transported to the spraying room for manual spraying, and the operator holds a spray gun to spray the valve body. In order to reduce the labor intensity of operators, in recent years, some automatic spraying equipment has also appeared. The conveying device is used to transport the valve body to the spraying room. There are multiple spray gun...
