From the aspect of carrying and feeding, the previous transport device may lack effective anti-skid measures, and the hardware fittings are prone to falling during transportation, which not only affects the feeding efficiency, but also may cause damage to the fittings. When the fittings enter the rust cleaning equipment, there is a lack of buffer design, which causes the fittings to enter with a large impact force, which damages the internal structure of the equipment and the fittings themselves, reduces the service life of the equipment and the quality of the fittings,

[0003] In terms of rust cleaning operation, the traditional stirring method cannot fully mix and contact the rust cleaning agent with the hardware fittings, the rust cleaning effect is poor, and the rust cleaning efficiency is low. Moreover, after rust cleaning, the separation speed of the rust cleaning agent and the hardware fittings is slow, which prolongs the entire rust cleaning process and affects the production progress. At the same time, improper treatment of the liquid and impurities after rust cleaning without effective filtration and classification collection not only wastes resources, but also increases the subsequent processing cost, and may also cause wear and tear to the equipment due to impurity residues. In addition, the traditional rust cleaning tool usually has a single function and cannot be flexibly adjusted according to different rust layer conditions, which cannot meet the diversified rust cleaning demands.

[0029] Working principle: First is the loading stage, hardware accessories are placed in the lower end of the conveyor 3, because the conveyor 3 is upwardly inclined, and the inner belt surface is bonded with an arc-shaped rubber stopper 301, which can effectively prevent the accessories from sliding off, and the accessories move upward with the belt, and after reaching the high end, they enter the rust removal tank 1 through the feeding port 101. The inclined rubber buffer sheet 102 at the bottom of the inner wall of the feeding port 101 can buffer the impact force when the accessories enter, avoiding damage to the inside of the rust removal tank 1 and the accessories themselves. After entering the rust removal tank 1, the rotating motor 601 is started to drive the rotating rod 602 to rotate, and the stirring rods 603 of different lengths and staggered arrangement on the rotating rod 602 and the outer rotating brush head 604 operate together. The stirring rods 603 promote the rust removal agent to fully mix with the hardware accessories, and the rotating brush head 604 directly brushes the surface of the accessories to enhance the rust removal effect. At the same time, the vibration motor 8 at the bottom of the rust removal tank 1 works to make the tank body vibrate, accelerate the separation of the rust removal agent and the hardware accessories, and also make the liquid and impurities after rust removal flow out more smoothly through the discharge pipe 7. In the cleaning and discharging link, the scraper 605 at the bottom of the rotating rod 602 rotates with the rotating rod 602, and the bottom of the brush material is attached to the inner bottom end of the rust removal tank 1, which cleans the residual rust, impurities and attached accessories, and helps them to flow out of the discharge pipe 7 with the liquid.
