After that, the painting mechanism 8 sprays anti-rust paint on the surface of the steel bars. By setting up this equipment, anti-rust paint can be sprayed on the hot-rolled steel bars after production, thereby preventing them from rusting when exposed to water during transportation.

At the same time, the rotating mechanism is opened, and the rotating mechanism drives the installation half ring 501 to swing back and forth as a whole, so that the three sets of steel brushes 521 can clean the steel bar without dead angles, and play the role of cleaning the surface impurities of the steel bar.

[0029] The hot-rolled steel bar rust prevention and protection device of the present invention includes an adjustment mechanism comprising a lifting plate 507, four sets of telescopic rods 508, and a first adjusting screw 509. The lifting plate 507 is connected to a rotating mechanism. The four sets of telescopic rods 508 are symmetrically installed on the front and rear sides of the bottom end of the lifting plate 507.

[0030] By setting up a lifting plate 507, telescopic rods 508, and a first adjusting screw 509, rotating the first adjusting screw 509 causes it to be threadedly connected to the work frame 1. The first adjusting screw 509 then drives the lifting plate 507 to move as a whole, and the four sets of telescopic rods 508 slide on the work frame 1. This allows the height of the cleaning mechanism 5, rinsing mechanism 6, drying mechanism 7, and painting mechanism 8 to be adjusted according to the thickness of the reinforcing bars, thus playing the role of height adjustment for the cleaning mechanism 5, rinsing mechanism 6, drying mechanism 7, and painting mechanism 8.

The first tooth 513 on the toothed plate 512 meshes with the second tooth 514 on the mounting half-ring 501. The second tooth 514 drives the mounting half-ring 501 to swing, which in turn drives the three sets of steel brush bristles 521 to swing. The swinging three sets of steel brush bristles 521 clean the reinforcing bars without dead angles, thus achieving the goal of cleaning the reinforcing bars without dead angles.

The two sets of guide plates 519 slide in the two sets of sliding grooves of the fixed plate 517.

[0034] By setting a fixed plate 517, a second adjusting screw 518, and a guide plate 519, the spacing of the three sets of steel brush bristles 521 is adjusted according to the thickness of the reinforcing bar. By rotating the three sets of second adjusting screws 518, the second adjusting screws 518 are threadedly connected to the three sets of fixed plates 517. The three sets of second adjusting screws 518 drive the three sets of portal frames 502 to move, thereby adjusting the spacing of the three sets of steel brush bristles 521, which serves to adjust the spacing of the three sets of steel brush bristles 521 according to the thickness of the reinforcing bar.

The anti-rust paint sprayed by the multiple sets of spray nozzles 802 is sprayed onto the surface of the steel bars. The exhaust gas generated when the anti-rust paint is sprayed onto the surface of the steel bars is introduced into the exhaust gas treatment equipment through the two sets of second exhaust pipes 805 and the first exhaust pipe 804 for treatment, which serves to paint the steel bars.

[0041] The hot-rolled steel bar rust prevention and protection device of the present invention, in operation, firstly rotates the first adjusting screw 509, which is threaded to 01. The first adjusting screw 509 drives the lifting plate 507 to move as a whole, and the four sets of telescopic rods 508 slide on the working frame 1, thereby adjusting the height of the cleaning mechanism 5, rinsing mechanism 6, drying mechanism 7 and painting mechanism 8 according to the thickness of the steel bar. Then, the spacing of the three sets of steel brush bristles 521 is adjusted according to the thickness of the steel bar. By rotating the three sets of second adjusting screws 518, which are threaded to three sets of fixed plates 517, the three sets of second adjusting screws 518 drive the three sets of gantry frames 50 2. Movement adjusts the spacing of the three sets of steel brush bristles 521. Then, three sets of motors 506 are turned on, which in turn drive three sets of power rollers 504. The three sets of power rollers 504 drive three sets of rotating belts 520 and the steel brush bristles 521 on them to move. The three sets of rotating belts 520 drive three sets of auxiliary rollers 505 to rotate. Then, the power mechanism 4 is turned on, which drives multiple sets of conveying mechanisms 2 through the transmission mechanism 3 to move the steel bars backward through the front multiple sets of conveying mechanisms 2. When the steel bars are inserted between the three sets of steel brush bristles 521, the three sets of steel brush bristles 521 clean the impurities on the steel bars. At the same time, the cylinder 511 is turned on, and the cylinder 511 drives... The toothed plate 512 moves back and forth, and the first tooth 513 on the toothed plate 512 meshes with the second tooth 514 on the mounting half-ring 501. The second tooth 514 drives the mounting half-ring 501 to swing, which in turn drives the three sets of steel brush bristles 521 to swing. The swinging three sets of steel brush bristles 521 clean the steel bars thoroughly. Then, the corrugated water inlet hose of the annular water pipe 601 is connected to the input end of the water supply equipment. Water enters the annular water pipe 601 through the corrugated water inlet hose and is sprayed out by multiple sets of nozzles 602. The water sprayed by the multiple sets of nozzles 602 washes away the loosened impurities on the steel bars. Then, the air inlet hose of the annular air duct 702 is connected to the fan, and the air duct... The air is introduced into the annular duct 702 through the intake hose. While the air is being introduced into the annular duct 702, it is heated by an electric heating wire. Then, the hot air is blown out through multiple sets of air outlets 701 to blow away the moisture on the surface of the steel bars. The hot air blown out by multiple sets of drying air outlets 703 dries the steel bars. Afterward, the anti-rust paint in the paint storage equipment is introduced into the annular spray pipe 801 through the feed pipe and sprayed out by multiple sets of spray nozzles 802.
