An automatic switching device for paint spraying lines

Abstract

This utility model discloses an automatic switching device for paint spraying pipelines, including a three-way ball valve; a main pipeline connected to the main interface of the three-way ball valve, which is connected to the equipment pipeline via a pipeline; branch pipelines connected to two secondary interfaces of the three-way ball valve, which are respectively connected to corresponding oil suction and filter pipelines; and a control component; the control component is connected to the switch handle of the three-way ball valve to drive the switch handle to rotate and switch the connection state of any branch pipeline. The device of this utility model drives a rotating arm to rotate via a drive mechanism, and the rotating arm drives the switch handle to rotate synchronously, thereby realizing the rotation of the valve core of the three-way ball valve to switch the on / off state of the branch pipelines. This automated control method avoids the resonance caused by the lifting tool trolley, which can lead to particle shedding and adhesion to the paint surface, causing coating quality problems and requiring rework. It also saves on raw material consumption and improves economic efficiency.
