Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a swing device for a spraying machine pipe. Background Art

[0002] Nowadays, various stage performances mostly use spray fireworks to create an atmosphere and promote the climax of the performance, which has achieved good results. However, most spray machines currently spray upward or downward, which is not convenient for flexible adjustment of the spray direction, resulting in a greatly reduced application range of the spray machine. Therefore, it is necessary to provide a spray machine that can change the spray direction for use.

[0003] Chinese patent CN202321265401.0 discloses a spraying machine that can change the spraying direction. By starting the double-axis servo motor to rotate forward, both rotating rods rotate forward. Under the transmission of the belt, the bidirectional threaded rod also rotates forward. The threaded block drives the connecting block, connecting rod and sliding rod to move left together, so that the spraying machine swings to the left. When the double-axis servo motor reverses, it can be seen from the above that the spraying machine swings to the right, achieving the purpose of facilitating the adjustment of the spraying angle. However, during use, the belt is very easy to slip, resulting in differential rotation of the screw rod, which affects the service life. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a swing device for a spray machine pipe with stable transmission, simple structure and low cost.

[0007] In this way, when in use, the rack is driven to move back and forth through the moving structure, and the reciprocating movement of the rack is converted into the reciprocating rotation of the gear, and then the spray machine pipe is driven to swing back and forth through the air inlet pipe to change the spraying direction of the spray machine.

[0008] Among them, the moving structure includes a reciprocating screw, both ends of the reciprocating screw are connected to the support through bearings, one end of the reciprocating screw passes through the support and is fixedly connected to the output shaft of the servo motor, the servo motor is fixedly installed on the support, and the reciprocating screw is provided with a nut slider that can move back and forth along the reciprocating screw, and the nut slider is fixedly connected to the rack.

[0009] Among them, a guide rod is fixedly installed in the support, and the guide rod is located below the reciprocating screw. The lower end of the nut slider is penetrated by a guide hole that slidably cooperates with the guide rod.

[0010] Wherein, a protrusion is fixed in the middle of the rack, and the support is provided with a sliding groove that slidably cooperates with the protrusion.

[0011] Wherein, a rubber pad is fixed to the lower end of the support.

[0012] In summary, the swing device for the spray flower machine pipe has the advantages of stable transmission, simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
