Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic powder spraying, in particular to a spraying device for an electrostatic powder spraying production line. Background Technique

[0002] The working principle of the electrostatic powder spraying method is almost exactly the same as that of the electrostatic spraying method of general liquid coatings. The difference is that the powder spraying is dispersed instead of atomized. The coating sprayed by the electrostatic powder spray gun makes the powder particles carry negative charges while being dispersed. The charged powder particles are affected by the airflow (or other acting forces such as centrifugal force) and electrostatic attraction, and are coated on the grounded object to be coated, and then heated and melted to cure into a film. The electrostatic powder spraying method is the dominant powder coating method in the industrial coating field. The electrostatic spraying device is composed of a spray gun, an operating device, and a powder bucket.

[0003] In the prior art, the powder bucket is usually placed on the base, and fixing plates are fixedly installed around the base to prevent the spraying device from shaking during movement, which may cause the powder bucket to tip over and collide.

[0004] However, the fixing plates fixed on the surface of the base cannot be stored, resulting in an uneven surface of the base. When the fixing plates are clamped too tightly, it is troublesome to take the powder bucket. Moreover, during long-term use of the powder bucket, the powder inside is prone to adsorb on the barrel wall and caking, resulting in poor spraying effect. Content of the Utility Model

[0010] Preferably, the rotating rod is a circular plate structure with a "T"-shaped cross-section, and sliding grooves are provided on both sides of the surface of one end of the rotating rod. The sliding groove is an arc groove with a "T"-shaped cross-section, and a sliding block is slidably connected to the surface of the sliding groove, and the sliding block is a "convex"-shaped plate structure.

[0011] Preferably, limiting grooves are provided on both sides of the surface of the fixing frame, the limiting grooves are square grooves and are connected with the sliding grooves, and one end of the sliding block is inserted into the surface of the limiting groove to brake the rotating rod.
