[0019] Figure 2 This is a three-dimensional structural diagram of the internal structure of this utility model;

[0020] Figure 3 This is a cross-sectional view of the present invention;

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 The cold flame spraying machine shown includes a housing 1. A feeding pipe 2 is fixedly connected inside the housing 1. A blowing device 3 is connected to the tail end of the feeding pipe 2, and a feeding device 4 is connected to the side wall of the feeding pipe 2.

[0024] To achieve 360° rotating spray, this invention designs a rotating spray mechanism, which includes a rotating sleeve 5 rotatably connected to a housing 1. The first end of a feeding pipe 2 is inserted into one end of the rotating sleeve 5, and the feeding pipe 2 and the rotating sleeve 5 can rotate relative to each other. A spray nozzle 6 is provided at the other end of the rotating sleeve 5, with one end inserted into the rotating sleeve 5 and the other end having a nozzle 61. A driving device 7 for driving the rotating sleeve 5 to rotate is provided between the housing 1 and the rotating sleeve 5. This design keeps the feeding pipe 2 fixed, while the rotating sleeve 5 drives the spray nozzle 6 to rotate, thereby achieving 360° spray.

[0025] Furthermore, the drive device 7 includes a motor 71 housed in the housing 1, a drive wheel 72 mounted on the output shaft of the motor 71, a driven wheel 73 mounted on the rotating sleeve 5, and a transmission belt connecting the drive wheel 72 and the driven wheel 73. The motor 71 drives the drive wheel 72 to rotate, which in turn drives the driven wheel 73 and the rotating sleeve 5 to rotate, thereby achieving the rotation of the nozzle 6.

[0026] Furthermore, a bearing 74 is provided between the rotating sleeve 5 and the housing 1 for rotatably connecting the two, so as to ensure the smooth rotation of the rotating sleeve 5.

[0027] Furthermore, the rotating sleeve 5 is located on the side of the housing 1, and the nozzle 6 is L-shaped. This structure makes it easier to achieve 360° rotating spray and makes the spray direction easier to control.

[0028] Furthermore, there is a gap B between the outer wall of the portion of the feeding pipe 2 that is inserted into the rotating sleeve 5 and the inner wall of the rotating sleeve 5. The design of the gap B not only reduces the friction and wear between the feeding pipe 2 and the rotating sleeve 5, but also supplements some air through negative pressure, which helps the cold flame material to burn and spray fully.

[0029] Furthermore, there is a gap C between the beginning of the feeding pipe 2 and the end of the nozzle 6. The gap C can prevent the feeding pipe 2 and the nozzle 6 from directly contacting each other, thereby reducing wear and forming a small buffer space, making the spraying of cold pyrotechnic material smoother.

[0030] Furthermore, the inner diameter D at the beginning of the feeding pipe 2 is smaller than the inner diameter E at the end of the rotating sleeve 5. This structural design can prevent the cold flaming material from getting clogged when entering the nozzle 6, allowing the cold flaming material to enter the nozzle 6 more smoothly and without residue from the feeding pipe 2, thereby ensuring the stability and continuity of the spray effect.

[0031] Furthermore, the feeding device 4 includes a storage hopper 41, a discharge valve 42 located below the storage hopper 41, and a screw conveyor mechanism 43 for conveying the cold flaming material falling from the storage hopper 41 into the feeding pipe 2.

[0032] For example, in this embodiment, the screw conveyor 43 adopts a single-axis screw conveyor mechanism, which includes a drive motor, a rotating screw shaft, and a fixed housing. The surface of the screw shaft is provided with screw blades. When the screw shaft rotates, the screw blades convey the cold flame material falling from the storage funnel 41 along the housing to the feeding pipe 2.

[0033] Furthermore, the blowing device 3 includes a fan 31 (such as a blower), and a concentrating pipe section 32 with a gradually decreasing inner diameter is provided between the air outlet of the fan 31 and the tail end of the feeding pipe 2 to improve blowing efficiency, increase wind speed, and make the cold flames spray higher and farther.

[0034] Furthermore, the blowing device 3, the feeding device 4, and the drive device 7 are electrically connected to a control system 8, and the control system 8 is connected to a remote control device 81. Users can remotely control various functions of the spraying machine through the remote control device 81, such as start, stop, rotation speed, spray volume, etc., thereby achieving more convenient and flexible operation.
