[0002] Plastic spraying guns are used in many fields. At present, flame spraying guns are mainly equipped with flame nozzles and plastic powder nozzles on the gun body. The flame nozzles will emit flames, so the flame nozzles have a higher temperature. The plastic powder produced 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, so that a large amount of liquefied plastic is easy to stick near the flame nozzle, and these sticky plastics may be blocked. Flame outlet and plastic powder outlet

Embodiment Construction
[0018] refer to figure 1 with figure 2 As shown, a plastic spraying gun that is not prone to clogging proposed by the present invention includes a plastic spraying gun main body, a plastic powder storage bottle 2, a powder gas mixing auxiliary device and a flame stabilizer;
[0019] The main body of the plastic spraying gun includes a gun shaft 11 and a gun handle 12. The gun shaft 11 is provided with a combustible gas introduction channel 111, a powder gas mixing chamber 112, a mixed gas delivery channel 113, an exhaust channel 114 and a plurality of oxygen introduction channels 115. The introduction channel 111, the powder gas mixing chamber 112, the mixed gas delivery channel 113 and the exhaust channel 114 are connected in sequence and arranged coaxially. The oxygen introduction channel 115 is arranged obliquely. The channels 115 are evenly distributed along the circumference of the exhaust channel 114; the plastic powder storage bottle 2 is detachably installed on the g...

The powder-gas mixing auxiliary device comprises a first communication tube and a spiral rod, the plastic powder storage bottle and the combustible gas guide-in passage are communicated through the first communication tube, and the spiral rod is mounted in the powder-gas mixing cavity and coaxial with the same. The flame stabilizer comprises a flame stabilizing frame and an ignition device, the flame stabilizing frame is detachably mounted on the gun barrel and positioned at the exhaust passage, and the ignition device is mounted on the flame stabilizing frame. The plastic spraying gun is convenient to use and effective in improvement of plastic spraying effects.
Description
technical field [0001] The invention relates to the field of plastic spraying, in particular to a plastic spraying gun which is not prone to clogging. Background technique [0002] Plastic spraying guns are used in many fields. At present, flame spraying guns are mainly equipped with flame nozzles and plastic powder nozzles on the gun body. The flame nozzles will emit flames, so the flame nozzles have a higher temperature. The plastic powder produced 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, so that a large amount of liquefied plastic is easy to stick near the flame nozzle, and these sticky plastics may be blocked. Flame ejection port and plastic powder ejection port. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a plastic spraying gun that is not prone to clogg...
