Abstract

The invention discloses a cold firework spark spraying machine. The cold firework spark spraying machine comprises a storage device, a feeding device, an electric heating device, an air supply device,a material suction pipe and a spark spraying pipe. The electric heating device is arranged on the feeding device. The storage device communicates with a feeding port of the feeding device. The material suction pipe is sleeved with the center in the spark spraying pipe. The lower portion of the material suction pipe communicates with a discharging port of the feeding device. The spark spraying pipe communicates with the air supply device. An air supply port of the air supply device is formed in the part, located behind a discharging port of the material suction pipe, of the spark spraying pipe. The cold firework spark spraying machine has the advantages that work is stable, and cold firework spraying form is good.

Description

technical field [0001] The invention belongs to cold pyrotechnic equipment, in particular to a cold pyrotechnic spraying machine. Background technique [0002] As a new type of stage atmosphere rendering equipment, cold pyrotechnic spraying machine is welcomed by the industry. The existing cold fireworks spraying machine is to use the screw feeding device to send the heated metal powder to the intersection of the feeding pipe and the spraying pipe, and then send air to the spraying pipe through the air supply device, and use the positive pressure airflow to send the metal powder It is sprayed out from the spray tube and burns to form cold fireworks. There are still some problems in the use of this spray machine: one is that the center of the spray is not correct, and it deviates from the center of the spray tube, which affects the spray effect; Metal powder bonding is easy to occur at the junction of the flower tubes and the wall of the flower spray tube, which affects its ...
