Problems solved by technology

[0002] In the traditional structure, the spray gun body is connected with the thermal fluid heating insulation block. When the needle valve piston rises, the fluid is directly sprayed vertically from the channel in the lower cover of the spray gun, or an L-shaped nozzle is installed to make the fluid fixed toward a Side spraying, when it is necessary to spray fluid on the inner or outer periphery of a square box or a round tank, it is necessary to insulate the entire spray gun body together with the heating part and the fluid heat supply pipe, solenoid valve, solenoid valve control line, The air pipes rotate together. Due to the limitation of the volume and self-weight of various pipelines and spray guns, the traditional spraying structure cannot rotate and spray in multiple circular cycles. At the same time, it is difficult to rotate the entire structure in a small radius space, resulting in poor spraying effect. Unable to meet market demand

Abstract

The invention relates to the technical field of glue spraying, in particular to a rotatable spray gun and a hot melt glue spray gun. The rotatable spray gun comprises a mounting seat, a glue sprayingdevice and a driving device which drives the glue spraying device to rotate. The glue spraying device comprises a spray gun body internally provided with a liquid glue accommodating cavity, and the spray gun body is fixedly arranged on the mounting seat through a base. The driving device comprises a motor, a motor seat and a driving shaft, the motor is fixedly arranged on the motor seat, the motorseat is fixedly arranged on the mounting seat through a driving shaft seat, one end of the driving shaft is connected to an output shaft of the motor, and the other end of the driving shaft is connected to a second gear. The motor drives the driving shaft to drive a first gear to enable a sleeve to rotate through the second gear. The hot melt glue spray gun further comprises a heat preservation and heating device which is fixedly arranged on the side of the spray gun body, and the heat preservation heating device can heat and heat preserve glue liquid installed on the spray gun body. The rotatable spray gun and the hot melt glue spray gun are simple in structures, reasonable in design, good in spraying glue effect and good in stability, are convenient to repair and maintain, and needs ofa market are met.
