Abstract

The invention is applicable to the technical field of air reservoir processing, and provides a paint gun and a paint spraying method for spraying paint inside an air reservoir. The paint gun for spraying the paint inside the air reservoir comprises a paint gun body and a spray nozzle, the spray nozzle comprises a connection head and a flow-guided structure, and the flow-guided structure is arranged in the connection head; the flow-guided structure comprises a circular ring clamping piece, a connecting rod, a flow-guided rod and a flow-guided plate; an end face of one side of the circular ringclamping piece is in clamped connection with a connecting end face between a circular truncated cone structure and a cylindrical structure; the flow-guided rod extends along the central axis of the circular ring clamping piece and is fixed on one side of the axial end face of the circular ring clamping piece through the connecting rod, and the diameter of the flow-guided rod is smaller than the minimum inner diameter of the circular truncated cone structure; and the flow-guided plate is arranged at one end, far away from the circular ring clamping piece, of the flow-guided rod, and is arrangedon the outer side of a paint powder outlet of the spray nozzle. According to the paint spraying method for spraying the paint inside the air reservoir, the spray nozzle is extended into the air reservoir for spraying paint powders, so that the paint spraying efficiency of the air reservoir is improved and the manufacturing time of the air reservoir is reduced.

Description

technical field [0001] The invention belongs to the technical field of gas storage tank processing, and in particular relates to a spray gun and a paint spraying method for spraying paint inside the gas storage tank. Background technique [0002] The air storage tank is a gas storage device in the automobile braking system. The air storage tank is a cylindrical hollow cylindrical structure. The air storage tank is used to store the gas compressed by the air compressor or air pump, and is used for automobile braking, whistle and other systems. [0003] In the prior art, in order to ensure the long-term use of the gas storage tank, it is necessary to spray paint on the inside and outside of the gas storage tank after the gas storage tank is gradually processed into a cylindrical hollow cylindrical structure through steel plates, so as to protect and prevent the steel material. Oxidation, thereby prolonging the service life of the air reservoir. At present, when spraying the a...
