Problems solved by technology
[0003] There may be so-called "overspray" during the spraying process, that is, powder spraying material that does not adhere to the surface of the workpiece. Dust is the main reason why the coating material cannot be closely combined with the workpiece, and the subsequent spraying particles drag the dust to the coating surface to form the retention in the coating, which affects the quality of the workpiece

Embodiment
[0019] figure 1 It is a structural schematic diagram of an electric arc wire material spray gun with a dust blowing mechanism of the present invention, as figure 1 As shown, the structure of the present invention includes a gun body 1 composed of a shell and a wire feeding mechanism placed inside the shell, a conductive tip and a compressed air pipe. Because the structure and principle of the spray gun are common knowledge in the art, it will not be discussed here. To repeat, the present invention also includes a dust blowing mechanism. The dust blowing mechanism includes a clamping sleeve 2 clamped on the outside of the shell and an air blowing unit connected to the clamping sleeve 2. One end of the blowing unit is connected to the clamping sleeve 2 through the toggle unit. Sliding connection, the other end of the air blowing unit is provided with a soot blowing port 6 facing away from the shell.
[0020] Specifically, the air blowing unit includes an intake hose connected t...

The invention discloses an electric arc wire material spray gun with a dust blowing mechanism, which includes a gun body composed of a casing, a wire feeding mechanism placed inside the casing, a conductive nozzle and a compressed air pipe. The invention also includes a dust blowing mechanism , the dust blowing mechanism includes a clamping sleeve clamped on the outside of the housing and a blowing unit connected to the clamping sleeve, one end of the blowing unit is slidably connected to the clamping sleeve through a toggle unit, The other end of the air blowing unit is provided with a soot blowing port facing away from the housing. The present invention adopts the electric arc wire material spray gun with dust blowing mechanism of the above structure. By setting the dust blowing mechanism, the soot blowing port can be adjusted to the direction of moving toward the spray gun by moving the vertical lever, so that Blow off the fine dust adhering to the workpiece and the unmelted and oversprayed spraying materials before the coating, avoiding the influence of the residue in the coating on the combination of the coating and the workpiece.
Description
technical field [0001] The invention relates to a hand-held electric arc wire material coating technology, in particular to an electric arc wire material spray gun with a dust blowing mechanism. Background technique [0002] Arc spraying is to contact two metal wires with positive and negative charges and usually the same chemical composition to generate an electric arc, instantly generate high heat to melt the tip of the wire, and then compress the air to atomize the molten wire spray material, and then accelerate Spray onto the surface of the substrate to form a coating after cooling. [0003] There may be so-called "overspray" during the spraying process, that is, powder spraying material that does not adhere to the surface of the workpiece. Dust is the main reason why the coating material cannot be closely combined with the workpiece, and the subsequent spraying particles drag the dust to the coating surface to form retention in the coating, affecting the quality of the...
