At the same time, each spray head 34 is correspondingly connected to a control valve 35.

[0019] In this embodiment, the feeding rack 1, the main frame 2, and the painting component 3 constitute the main body structure of the liquefied gas tank painting device involved in this application.

[0020] Among them, the main frame 2 is set as a rectangular frame structure with a hollow interior and an open upper side.

[0021] It should be noted that before spraying the liquefied gas tank, lift its bottom up to have some gaps so that it is placed on the conveyor belt 111 at the bottom of the inclined rack 112, and then it can be conveyed by means of the friction force of the conveyor belt 111. When the spraying is completed, directly lift it out of the main frame 2, which can save one lifting operation. For a full and heavy liquefied gas tank, it plays a role in reducing the burden during batch spraying.

[0022] Refer to Figure 1 , the feeding rack 1 is set as a right-angled triangle frame structure with a hollow interior. The outer end of the feeding roller 114 at the top is connected to a feeding motor 116 through a belt pulley 113 and a transmission belt 115. At the same time, the feeding motor 116 is installed inside the feeding rack 1. A guiding plate 13 is connected to the outside of the guiding roller 14, and the guiding plate 13 is set to be inclined towards the turntable 23. Both the guiding roller 14 and the transition roller 12 are freely rotating rollers.

[0023] In this embodiment, the belt pulley 113 is simultaneously connected to the outer end of the feeding roller 114 and the outer end of the output shaft of the feeding motor 116, and the two belt pulleys 113 are connected through a transmission belt 115, so as to drive the conveyor belt 111 to drive.

[0024] As a preferred implementation method, by setting the guiding plate 13 and the guiding roller 14, it is convenient to slide the liquefied gas tank onto the turntable 23.

[0025] Reference Figure 1 Figure 1 , a rotary motor 25 is connected to the lower end of the turntable 23, a ring groove seat 26 is arranged outside the rotary motor 25, a support rod 24 is connected to the lower end of the turntable 23, and the lower end of the support rod 24 is slidably connected to a ring groove cavity formed in the upper end of the ring groove seat 26. A photoelectric sensor 22 is arranged outside the turntable 23, and the photoelectric sensor 22 protrudes above the upper end surface of the turntable 23. At the same time, the photoelectric sensor 22 is electrically connected to the electric push rod 213 through an external controller.

[0026] As a preferred embodiment, by arranging the support rod 24 and the ring groove seat 26, an auxiliary support effect on the rotation of the turntable 23 is achieved.

[0027] As a preferred embodiment, by arranging the photoelectric sensor 22, when the liquefied gas tank is placed at the middle position of the turntable 23, it can be detected and sensed, and then the electric push rod 213 can be started.

A guide rod 214 is connected through the outer arc surface of the arc-shaped plate 211, and the guide rod 214 slidably penetrates through the outer wall of the main frame 2.

[0029] As a preferred embodiment, the clamping effect is achieved by arranging the arc-shaped plates 211, and the balls 212 achieve rolling friction with the outer wall of the liquefied gas tank, reducing the frictional resistance generated by clamping.

[0030] During use, start the feeding motor, move the liquefied gas tank to the low end of the inclined rack, and then convey it upward by means of a conveyor belt. Keep the liquefied gas tank stable by hand during the process, and then slide the liquefied gas tank towards the turntable inside the main frame through the transition roller and the guide roller until the bottom of the liquefied gas tank is placed on the turntable. At the same time, when it is detected by the photoelectric sensor, the electric push rod can be started to push the arc-shaped plate towards the liquefied gas tank until the balls contact the outer wall of the liquefied gas tank. Then start the rotary motor and the paint pump, so that the liquefied gas tank rotates automatically during the painting process to complete uniform spraying.
