[0002] Plastic spraying guns are used in a wide range, mainly including flame spraying guns and electrostatic plastic spraying guns. Flame spraying guns are mainly equipped with flame nozzles and plastic powder nozzles on the gun body. The flame nozzles will eject flames, so the flame nozzles have relatively High temperature, the plastic powder sprayed through the plastic powder nozzle is liquefied under the action of high temperature. In order to ensure that all the plastic powder can be liquefied, there must be sufficient temperature at the flame nozzle, but due to the inconsistent distance between the powder and the flame nozzle, resulting in The powder close to the flame outlet is easy to gasify

The invention provides a plastic spraying gun with an excellent plastic spraying effect. The plastic spraying gun comprises a plastic spraying gun body, a powder bottle, a mixing mechanism, a gas supply mechanism and a flame holder. The plastic spraying gun body comprises a gun barrel and a gun stock. An oxygen guiding and feeding channel, a powder and gas mixing cavity and a liquid storage cavity are formed in the gun barrel. The oxygen guiding and feeding channel communicates with the powder and gas mixing cavity. The powder bottle is detachably mounted on the gun barrel. The mixing mechanism comprises a first communicating pipe, a gas guiding device and a plurality of flow guiding plates. The first communicating pipe communicates with the powder bottle and the oxygen guiding and feeding channel. The gas supply mechanism comprises a plurality of flammable gas guiding and feeding pipes and a plurality of second communicating pipes. The flame holder comprises a flame holding frame, an ignition device, a plurality of liquid storage pipes and a plurality of flow guiding pipes. The flame holding frame is detachably mounted on the gun barrel and located at gas outlets of the flammable gas guiding and feeding pipes. The ignition device is mounted on the flame holding frame. The plastic spraying gun is convenient to use, and the liquefying effect of plastic powder is excellent.
