DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example

[0031] like Figure 1 , Figure 2 As shown, the square hollow profile inner cavity spraying device includes a bottom plate 10 and a square profile 60, and the spraying device also includes:

[0032] A driving mechanism 30, the driving mechanism 30 is mounted on the top of the base plate 10;

[0033] The frame 20 is disposed above the bottom plate 10. The number of the frame 20 is not less than two and they are located on the same axis. In this embodiment, the number of the frame 20 is two;

[0034] The spraying mechanism 50 includes a spray head 54, a circular protrusion 52 and a rotating member 58. The rotating member 58 drives the spray head 54 to move around the square inner groove of the circular protrusion 52.

[0035] The main rod 41 is used to connect the driving mechanism 30 and the spraying mechanism 50. The driving mechanism 30 drives the spraying mechanism 50 to axially extend into the center of the inner cavity of the square profile 60, and cooperates with the square circumferential motion of the nozzle 54 to achieve uniform spraying of the square inner cavity of the square profile 60.

[0036] The working process of the spraying device of the present invention is as follows: firstly, the square profile 60 is Figure 2 As shown, it is placed on the frame 20, and then the driving mechanism 30 and the rotating member 58 work. Under the connection of the main rod 41, the driving mechanism 30 can drive the spraying mechanism 50 to move horizontally as a whole axially and extend into the center of the inner cavity of the square profile 60. At the same time, the rotating member 58 drives the spray head 54 to move in a square circle, thereby realizing automatic and uniform spraying of the square inner cavity of the square profile 60, saving time and effort and achieving good spraying effect.

[0037] The inner wall of the frame 20 is installed with a universal ball 21; by providing the universal ball 21, the sliding friction of the square profile 60 during the process of being placed on the frame 20 is changed to rolling friction, reducing resistance and facilitating the placement and removal of the square profile 60.

[0038] The bottom of the frame 20 is fixedly connected with a support leg 22 , and the support leg 22 is fixedly connected to the top of the bottom plate 10 .

[0039] The top of the bottom plate 10 is fixedly connected with a vertical plate 11, and a horizontally arranged guide cylinder 111 is fixedly inserted on the vertical plate 11, and the main rod 41 is slidably connected to the inner wall of the guide cylinder 111. The vertical plate 11 and the guide cylinder 111 play the role of auxiliary support for the main rod 41, ensuring the stability of the horizontal movement of the main rod 41 under the drive of the driving mechanism 30.

[0040] The main rod 41 has a plurality of branches 411 extending explosively from one end close to the spraying mechanism 50, and the plurality of branches 411 are used to fix the spraying mechanism 50. By providing the branches 411, not only the contact area of ​​the connection between the main rod 41 and the spraying mechanism 50 is increased, the stability of the connection is ensured, and at the same time, the connection between the branches 411 and the spraying mechanism 50 is located at the edge of the square plate 51, providing a better installation position for the rotating member 58 in the spraying mechanism 50.

[0041] The driving mechanism 30 includes a servo motor 31 fixedly mounted on the top of the base plate 10 . The output shaft of the servo motor 31 is mounted with a threaded rod 32 .

[0043] The top of the bottom plate 10 is fixedly connected with a stabilizing plate 35, and the inner side of the stabilizing plate 35 is rotatably connected to the tail end of the threaded rod 32.

The tail end of the movable tube 53 extends to the square groove of the round protrusion 52, and the head end is connected to the nozzle 54.

[0046] The head end of the rotating tube 57 is connected to the movable tube 53 through the telescopic through tube 56 .

[0047] The working process of the spraying mechanism 50 includes the square circumferential motion of the spray head 54 and the liquid supply to the spray head 54: the square circumferential motion of the spray head 54 is driven by the rotating member 58 to drive the rotating tube 57 to rotate, and the rotating tube 57 rotates to drive the hollow plate 55 to rotate synchronously. Under the connection of the telescopic through pipe 56 and the guidance of the square groove of the round protrusion 52, the hollow plate 55 rotates to drive the movable tube 53 and the spray head 54 to move in a square circumferential manner;

[0048] Liquid supply to the nozzle 54: the liquid supply member 59 supplies liquid to the rotating tube 57, the rotating tube 57 supplies liquid to the movable tube 53 through the telescopic through tube 56, and finally the liquid is sprayed out from the nozzle 54.

[0049] The rotating member 58 includes a micro motor 581 fixedly mounted on the square plate 51. The output shaft of the micro motor 581 is fixedly connected to a gear disk 583. An outer gear ring 582 is fixedly sleeved on the outer periphery of the tail end of the rotating tube 57, and the outer gear ring 582 and the gear disk 583 are meshed for transmission.
