In order to achieve the purpose, the method adopted by the invention is as follows: a spray gun for coating comprises a gun main body, an electrostatic pipeline, a powder inlet pipeline and a mixing cavity; the utility model discloses a powder spraying gun, including rifle body, powder inlet pipe, magnet baffle, mixing chamber, power supply, the inside center pin symmetric distribution about the center pin of rifle body has two powder inlet pipe ways that advance, still be equipped with the magnet baffle that can reciprocate in the middle of the powder inlet pipe way, the polarity at two magnet baffle both ends is also about the center pin symmetry of rifle body, the magnet baffle will the powder inlet pipe way separates into two parts, it puts the thing chamber still to be equipped with in the middle of two powder inlet pipe ways, put the thing intracavity and placed the electro-magnet, wire on the electro-magnet is connected on variable frequency power supply, two ends that advance the powder pipeline all with the mixing chamber intercommunication, the mixing chamber still communicates there is the electrostatic pipeline.
As an improvement of the invention, a spout baffle is sleeved outside the rubber nozzle.
As an improvement of the invention, the two magnet baffles and the electromagnet are on the same vertical plane.
As an improvement of the invention, two ends of the magnet baffle are provided with limiting transverse plates.
As an improvement of the invention, sealing gaskets are arranged inside the powder inlet pipeline and positioned on two sides of the magnet baffle.
Has the advantages that:
the spray gun for coating carries out spraying operation by adopting the alternate circulating powder supply mode of the two powder inlet pipelines which are symmetrically distributed up and down, effectively avoids the problems of discontinuous powder supply and uneven powder supply caused by poor flowability of sprayed powder, ensures uniform spraying of the powder on a workpiece, and has simple structure and convenient operation.
Drawings
Fig. 1 is a schematic structural view of the present invention.
The components in the figure are:
1-gun body, 2-electrostatic pipeline, 3-powder inlet pipeline, 4-mixing cavity, 5-magnet baffle, 6-storage cavity, 7-electromagnet, 8-conical port, 9-rubber nozzle, 10-nozzle baffle, 11-limiting transverse plate and 12-sealing gasket.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings, it being understood that the following detailed description is illustrative of the invention only and is not intended to limit the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
A spray gun for coating as shown in fig. 1, which comprises a gun body 1, an electrostatic pipeline 2, a powder inlet pipeline 3 and a mixing chamber 4; the utility model discloses a powder spraying gun, including rifle body 1, the inside center pin symmetric distribution of rifle body has two powder inlet pipe way 3 about, still be equipped with the magnet baffle 5 that can reciprocate in the middle of the powder inlet pipe way 3, the polarity at two magnet baffle 5 both ends is also about the center pin symmetry of rifle body 1, magnet baffle 5 will powder inlet pipe way 3 separates into two parts, it puts thing chamber 6 still to be equipped with in the middle of two powder inlet pipe way 3, it has placed electro-magnet 7 in the thing chamber 6 to put, the wire on the electro-magnet 7 is connected on variable frequency power supply, two powder inlet pipe way 3 terminal all with mixing chamber 4 intercommunication, mixing chamber 4 still communicates there is electrostatic pipe 2, mixing chamber 4 is equipped with bell 8 near the head department of rifle body 1, the outside cover of bell 8 is equipped with rubber nozzle 9.
The principle of the invention is as follows: the spray gun for coating disclosed by the invention mainly utilizes two powder inlet pipelines to alternately supply powder, when electromagnets are electrified, one magnet baffle closes the powder inlet pipeline for storing dust due to opposite attraction, and the other magnet baffle opens due to like repulsion so that the dust stored in the powder inlet pipeline enters a mixing cavity for spraying; because the conducting wire on the electromagnet is connected to the variable frequency power supply, when the power supply electrode is exchanged, the polarity of the electromagnet is also exchanged, the magnet baffle which is closed before is opened, and the magnet baffle which is opened before is closed, so that the two powder inlet pipelines alternately supply powder to finish the spraying operation in cycles.
As an embodiment of the invention, a spout baffle 10 is sleeved outside the rubber nozzle 9. The nozzle baffle is used for preventing wind power from blowing away spraying dust to influence the flatness of a spraying surface, and is used for limiting the spraying range of the nozzle and preventing the powder from being sprayed to a coated part.
As an embodiment of the present invention, the two magnet baffles 5 and the electromagnet 7 are on the same vertical plane. The magnet shield in this position receives the greatest force and works alternately with the spray.
In an embodiment of the present invention, two ends of the magnet baffle 5 are provided with a limiting transverse plate 11. The spacing diaphragm is mainly for the removal of restriction magnet baffle, prevents that magnet baffle breaks away from going out.
In one embodiment of the present invention, the powder inlet pipe 3 is provided with sealing gaskets 12 at two sides of the magnet baffle 5. Mainly for guaranteeing the leakproofness of advancing the powder pipeline.
The spray gun for coating provided by the invention adopts the alternate and cyclic powder supply mode of the two powder inlet pipelines which are symmetrically distributed up and down to carry out spraying operation, effectively avoids the problems of discontinuous powder supply and uneven powder supply caused by poor flowability of the sprayed powder, ensures uniform spraying of the powder on a workpiece, and has the advantages of simple structure and convenient operation.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but any modifications or equivalent variations made according to the technical spirit of the present invention are within the scope of the present invention as claimed.
