Abstract

The invention discloses an automatic retracting device for a spray gun. The automatic retracting device comprises a spray gun, a shield cylinder, a spring, a piston, an intake pipeline, and an exhaust pipeline. The piston is fixed at one end of the spray gun. The other end of the spray gun extends out of an exit of the shield cylinder. The piston is hermetically connected with the inner wall of the shield cylinder. The spring is sleeved on the spray gun. The intake pipeline and the exhaust pipeline are disposed in the sealed space formed by the piston and the shield cylinder.

Description

technical field [0001] The invention relates to a spray gun, in particular to an automatic advance and retreat device for a spray gun. Background technique [0002] Traditional spray guns are mainly driven by sprockets, gears, etc. to advance and retreat the spray gun, and to adjust the extension length of the spray gun. [0003] The problems of this traditional spray gun automatic advance and retreat device are: (1) The structure is complex and the processing cost is high; (2) It is impossible to accurately control the extension of the spray gun to any length; (3) It is prone to lubrication failure, jamming and other failures ; (4) The operation is cumbersome, the maintenance requirements are high, and the reliability is low. Contents of the invention [0004] In order to solve the problems existing in the prior art, the object of the present invention is to provide a spray gun automatic advancing and retreating device with simple structure, low processing cost, accurate...
