[0023] Among them, the use of the sprayer 108 for spraying can effectively acidify the surface of the stainless steel rod, ensuring the basic function of the device, and setting two sprayers 108 can ensure the acidification effect, and there will be no shortage of acidizing liquid, which improves the reliability of the device.

[0024] A protective shell 112 is installed in the middle of the upper surface of the horizontal plate 106, and the outer side of the sprayer 108 is slidably connected to the side wall of the protective shell 112. Storage boxes 117 are installed on both sides of the upper side of the horizontal plate 106 and located outside the protective shell 112. The bottom pipeline of the storage box 117 is connected to the side wall of the protective shell 112. A pipeline is arranged in the side wall of the protective shell 112, and the two ends of the pipeline are respectively connected to the sprayer 108 and the storage box 117. The top of the storage box 117 is provided with a heating A relay 113 is installed in the center of the top of the protective shell 112, and wires 114 are set at both ends of the relay 113. The two wires 114 are connected to the motor 115 and the motor 2 116 respectively. The output end of the motor 115 is connected to the rotating gear 110, and the output end of the motor 2 116 is connected to the rotating gear 2 111. The rotation directions of the motor 115 and the motor 2 116 are opposite, and the motor 115 and the motor 2 116 will not be started at the same time.

[0025] Specifically, the relay 113 is used to control the motor 115 and the motor 2 116, so that the rotating gear 110 and the rotating gear 2 111 cooperate with each other, so that the two sprayers 108 can slide back and forth in the slide groove 107.

The conveyor belt 102 is arranged above the rotating shaft 104, and the discharge belt 1021 is arranged below the rotating shaft 104.

[0028] Specifically, the stainless steel rods are lowered section by section on the inclined rotating shafts 104, so that the stainless steel rods can be turned over better without manual turning. In addition, the discharge belt 1021 can be used to directly transport the stainless steel rods to the next step for drying after spraying, thereby ensuring the acidification effect.

[0029] The working principle and use process of the utility model are as follows: first, the device is started and each structure is checked to see if it is working properly. Then, the stainless steel rod that needs to be acidified is conveyed through the conveyor belt 102. When the stainless steel rod falls onto the rotating shaft 104, it rolls downward along the rotating shaft 104 driven by gravity and inertia. At the same time, the relay 113 controls one of the motors 115 or 116 to start, thereby driving the corresponding rotating gear 110 or the rotating gear 2 111 to drive the gear belt 109 to move, and finally drives the two sprayers 108 to slide and spray in the chute 107. Finally, the stainless steel rod after spraying falls onto the discharge belt 1021 and is conveyed to the next process.
