Description

Technical Field

[0001] The present application relates to the technical field of cold flame equipment, and in particular to a cold flame rotating waterfall-type eruption equipment. Background Art

[0002] The cold fire waterfall equipment can spray cold fire waterfalls in performances and evening parties, which can decorate the stage and enhance the performance atmosphere. In order to match the stage effect, the cold firework needs to be able to rotate when it erupts. The rotation speed and angle should be adjusted according to actual needs. Especially when used in a dynamic and rhythmic atmosphere, it needs to have a faster rotation speed and be able to quickly switch the rotation angle.

[0003] When the existing equipment rotates, the material box inside the machine will rotate with it. When the rotation angle is slightly large, the cold flame raw material (usually metal powder) in the material box will shake, causing the screw rod of the feeding motor to be unable to feed evenly or even unable to feed, resulting in poor spraying effect and a lot of residual material.

[0054] The injection pipe 41 is rotatably arranged on the frame 1, while the feeding mechanism 2 and the feeding heating mechanism 3 are kept relatively still. This can not only enable the injection pipe 41 to rotate during the eruption process to provide the required cold fireworks effect, but also ensure the stability of the supply of cold fireworks raw materials, thereby ensuring that the fireworks are continuous during the rotation process and the height of the fireworks remains stable.

[0055] The cold flame rotating waterfall-type eruption equipment provided by the present patent application has only the ejection pipe 41 rotating while other mechanisms remain relatively still, so that the rotation of the ejection pipe 41 is not affected by the feeding, heating and other mechanisms, and can rotate quickly while maintaining the stability of the eruption, and the rotation angle is wide. It can be hung at a high place, so that the ejection pipe 41 can rotate during the eruption process, with the pipe mouth facing downward, providing a cold flame effect like a waterfall. At the same time, the ejection pipe 41 is light in weight, and the energy consumption of driving its rotation is low. In addition, when packaging and transporting, only the ejection pipe 41 needs to be fixed to achieve the fixation of the entire equipment, which is convenient and fast with few hidden dangers.

In addition, by adjusting the size of the assembly hole through the locking assembly part, the device can be connected with other components of different sizes, thereby improving the wide application of the device.

[0058] Optionally, the assembly gripper includes a first gripper and a second gripper that are hingedly matched, the first gripper and the second gripper are buckled with each other to form an assembly hole, one end of the locking assembly is matched with an end of the first gripper away from the second gripper, and the other end of the locking assembly is threadedly matched with the second gripper, thereby achieving a locking connection effect through the locking assembly. For easy operation, a rotating handle can also be provided at the end of the locking assembly, which is convenient for the user to hold and perform rotational driving work.

[0059] Optionally, the assembly clamp is hingedly arranged on the mounting plate 12. By hingedly arranging the assembly clamp on the mounting plate 12, it is convenient to adjust the position of the assembly clamp so that it can be stably matched with other components. In addition, when the device is not hung, the assembly clamp can be rotated to be horizontally placed on the mounting plate 12, thereby reducing the space occupied by the device and facilitating storage and transportation.

[0060] In some embodiments, the cold flame rotating waterfall spraying device further includes a heating mechanism 3 disposed in the first housing 13, and the heating mechanism 3 includes:

[0061] A feeding pipe 31, whose feeding end is connected to the feeding mechanism 2, and whose discharging end is connected to the injection pipe 41 along the rotation axis of the injection pipe 41;

[0062] A feeding motor 33, a feeding screw 32 is connected to a rotating end of the feeding motor 33, and the feeding screw 32 is rotatably disposed in the feeding tube 31; and

[0063] The heating coil 34 is wound around the outer wall of the feeding pipe 31 .

[0064] Among them, the feeding motor 33 drives the feeding screw 32 to rotate in the feeding tube 31, and the cold flame raw material is moved forward by the feeding screw 32. At the same time, the heating coil 34 continuously heats the feeding tube 31, and the cold flame raw material absorbs heat during the movement, and the temperature reaches the set temperature, and is sent to the injection tube 41 for spraying. Preferably, a heat preservation shell 35 is also provided on the outside of the heating coil 34 to reduce heat loss.

[0065] Reference Figure 1-Figure 9 In some embodiments, the feeding mechanism 2 includes a material box 21 and a feeder, and the feeder is used to transport the raw materials in the material box 21 to the feeding pipe 31; wherein the feeder can be any driver that can realize feeding in the prior art, such as a motor. In this application, the feeder is a feeding motor, and the feeding motor transports the cold flame raw materials stored in the material box 21 to the feeding pipe 31.

[0066] The feeding mechanism 2 also includes a feeding funnel 22, and the end of the feeding funnel 22 with a large inner diameter is connected to the material box 21, and the end with a small inner diameter is connected to the feeding pipe 31; the amount of cold flame raw material entering the feeding pipe 31 each time is small, or the cold flame raw material is continuously fed into the feeding pipe 31 in a small amount, thereby ensuring that the cold flame raw material in the feeding pipe 31 can be fully heated.

[0067] In some embodiments, the injection mechanism 4 is disposed in the accommodating space 15, and the injection mechanism 4 includes a connected air source 42 and an injection pipe 41, the injection port of the injection pipe 41 is disposed downward, and the injection pipe 41 is rotatably disposed on the frame 1, and the air source 42 is used to supply airflow into the injection pipe 41. The air source 42 can be disposed at one end of the injection pipe 41 and rotate synchronously with the injection pipe 41; of course, the air source 42 can also be disposed relatively statically, and the airflow is supplied from the rotation axis of the injection pipe 41.

[0068] Preferably, the gas source 42 is disposed at one end of the injection tube 41 and rotates synchronously with the rotation of the injection tube 41. The airflow supplied by the gas source 42 is along the axial direction of the injection tube 41, so that the cold flame raw material can be sprayed out more thoroughly and a better eruption effect can be achieved, forming flower-shaped cold flames or other forms of cold flames.

[0069] In some embodiments, the side wall of the injection pipe 41 is also provided with a rotating rod, the frame 1 is provided with a bearing 11 that cooperates with the rotating rod, the feeding pipe 31 and the inner cavity of the injection pipe 41 are movably sealed; the rotating axis of the rotating rod and the center of the movable seal of the feeding pipe 31 are located on the same straight line.

[0070] Preferably, a rotating rod is provided at a position symmetrical to the side wall of the injection pipe 41 and the feeding pipe 31. The rotating rod is fixedly connected to the outer wall of the injection pipe 41 and cooperates with the bearing 11 of the frame 1 to receive the power of the driving mechanism 5 to drive the injection pipe 41 to rotate; the symmetry here refers to the rotation axis of the rotating rod when it rotates (that is, the rotation axis of the injection pipe 41 when it rotates), which is located on the same straight line as the center of the movable seal of the feeding pipe 31 and the injection pipe 41, thereby ensuring that during the rotation of the injection pipe 41, the cold flame raw material transported by the feeding pipe 31 can be continuously input into the inner cavity of the injection pipe 41.

[0071] The movable seal between the feeding pipe 31 and the injection pipe 41 can be achieved by using a conventional movable sealing structure in the art, which will not be described in detail in this embodiment.

[0072] Reference Figure 1-Figure 9 , the driving mechanism 5 includes a power component 51, and the rotating end of the power component 51 is rigidly connected to the rotating rod through a connecting rod 52; the power component 51 is used to drive the connecting rod 52 to rotate, and the connecting rod 52 is rigidly connected to the rotating rod, so the rotation of the connecting rod 52 will drive the synchronous rotation of the rotating rod, thereby realizing the rotation of the driving injection tube 41. In addition, in the present application, by directly connecting the rotating end of the power component 51 to the connecting rod 52, there is no need to use other transmission components for connection, so the structure is simple and the cost is reduced. Of course, the power component 51 can use any component that can realize driving rotation in the prior art, such as a power motor, a rotating cylinder or a power motor.

[0073] In addition, the driving mechanism 5 may further include a gearbox 53, which can better control the rotation speed of the injection pipe 41. The gearbox 53 cooperates with the connecting rod 52 and the power component 51 to achieve speed control, position control, and stroke control of the injection pipe 41.

[0074] The driving mechanism 5 further includes a positioning piece 54 disposed on the frame 1, and the positioning piece 54 is used to limit the rotation range of the injection pipe 41. When the injection pipe 41 or a structure connected thereto rotates to abut against the positioning piece 54, the rotational power mechanism provides reverse power to switch the rotation direction of the injection pipe 41. One or more positioning pieces 54 may be provided, and a buffer layer may be provided on the positioning piece 54 to prevent the injection pipe 41 or the positioning piece 54 from being damaged due to collision.
