A multi-gun automatic spraying device capable of uniformly distributing powder

Abstract

This utility model relates to the field of powder coating technology, specifically to a multi-gun automatic spraying device capable of uniformly distributing powder. It includes a base and a multi-gun device. The top of the base is equipped with a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism includes a column, a cylinder, a ring frame, an adjustment frame, a connecting seat, an adjustment rod, and ball bearings. The first adjustment mechanism causes the cylinder and ring frame to cooperate in driving the adjustment frame to swing. The swinging adjustment frame then drives the multi-gun device to move radially, adjusting the radial angle of the multi-gun device. The second adjustment mechanism causes a motor to drive a connecting rod to swing. The swinging connecting rod then drives the multi-gun device to move axially, adjusting the axial angle of the multi-gun device. This facilitates the adjustment of both the radial and axial angles of the multi-gun device, effectively improving the spraying range and the uniformity of powder distribution.
