In order to improve the durability and service life of steel bars, rust prevention treatment has become an important step. Traditional rust prevention methods usually use brushing or soaking, which are inefficient and have poor uniformity. Atomized spraying technology uses a high-efficiency spraying device to evenly coat the rust inhibitor on the surface of the steel bars, which has better effect and higher level of automation.

[0003] Chinese patent CN213855340U discloses a rebar rust inhibitor atomizing spraying device, including a base. Two support columns are fixedly installed on the lower left and right sides of the base. A rebar storage box is fixedly installed on the lower rear of the base. A pushing device is inserted into the middle of the upper end of the base. A spraying box is fixedly installed on the upper front of the base. A spraying device is fixedly installed on the middle of the upper end of the spraying box. A feed inlet is fixedly installed on the lower front of the spraying box.

A drying device is fixedly installed on the middle upper end of the drying box. A discharge port is fixedly installed on the lower rear end of the drying box. This patent uses a spraying device for rust prevention, improving the preservation quality of rebar and reducing maintenance costs. The pushing device also improves the work efficiency of the staff.

[0004] However, the current device has the following problems: residual rust remover drips from the atomizing nozzle, causing equipment contamination and wasting rust inhibitor, which will affect the uniformity and quality of the next spraying and reduce the rust prevention effect. Therefore, we propose a steel reinforcement rust inhibitor atomizing spraying device. Utility Model Content

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-3As shown, a rebar rust inhibitor atomizing spraying device includes a support base 1. Two rotating shafts 2 are rotatably connected to the inner wall of the support base 1. One of the rotating shafts 2 is driven by a motor, which is fixedly connected to the side of the support base 1. Pushing belts 3 are rotatably connected to the circumferential surfaces of the two rotating shafts 2. Rebar is placed on the pushing belts 3, and the motor is started to rotate the rotating shafts 2, thereby pushing the rebar with the pushing belts 3. The side of the spray box 6 is equipped with an anti-drip device 4 to prevent rust inhibitor dripping from the atomizing nozzles of the spray box 6 when not in use. The anti-drip device 4 includes a moving groove 41. A trough 41 is located on the side of the spraying box 6. A baffle plate 42 is slidably connected to the inner wall of the movable trough 41. The spraying box 6 is fixedly connected to the top of the support base 1. The reinforcing steel enters the spraying box 6 through the feed inlet 9. While the rust remover is sprayed out, the atomizing nozzle at the front end atomizes the rust remover. A drying box 7 is fixedly connected to the top of the support base 1. After the reinforcing steel is sprayed, it enters the drying box 7 through the connecting pipe 8. The heater in the drying box 7 heats the air and then delivers the air. A connecting pipe 8 is fixedly connected to the top of the support base 1. A reinforcing steel storage box 11 is fixedly connected to the inner wall of the support base 1. The conveyor belt 3 feeds the reinforcing bars into the reinforcing bar storage box 11 through the discharge port 10. The side of the connecting pipe 8 is fixedly connected to the side of the spraying box 6, and the side of the connecting pipe 8 away from the spraying box 6 is fixedly connected to the side of the drying box 7. The side of the spraying box 6 away from the connecting pipe 8 is fixedly connected to the inlet 9, and the side of the drying box 7 away from the connecting pipe 8 is fixedly connected to the outlet 10. The anti-drip device 4 also includes a fixing block 43 fixedly connected to the side of the spraying box 6. An elastic telescopic rod 44 is fixedly connected to the side of the fixing block 43, and a moving block 45 is fixedly connected to the telescopic end of the elastic telescopic rod 44. The bottom of the movable block 45 is fixedly connected to the top of the shielding plate 42. An L-shaped support plate 46 is fixedly connected to the side of the support base 1. A rotating rod 47 is rotatably connected to the inner wall of the L-shaped support plate 46. The rotating rod 47 is driven by a motor, and the motor is fixedly connected to the side of the L-shaped support plate 46. A rotating ring 48 is fixedly connected to the circumferential surface of the rotating rod 47. A semi-circular block is fixed to the side of the movable block 45 away from the elastic telescopic rod 44. A semi-circular block is fixed to the circumferential surface of the rotating ring 48. The semi-circular surface of the movable block 45 is located on the movement trajectory of the semi-circular surface of the rotating ring 48.

[0025] According to the above structure, the reinforcing steel is placed on the pusher belt 3, and then the drive assembly of the pusher belt 3 is activated to move the pusher belt 3, thereby pushing the reinforcing steel into the spray box 6 for spraying. While pushing the reinforcing steel, the motor corresponding to the rotating rod 47 is activated. The output shaft of the motor causes the rotating rod 47 to rotate. The rotation of the rotating rod 47 drives the rotating ring 48 to rotate. The rotation of the semicircular block of the rotating ring 48 will abut against the semicircular block of the moving block 45, thereby causing the moving block 45 to drive the shielding plate 42 to move along the moving groove 41 away from the rotating ring 48. At the same time, the moving block 45 will squeeze the elastic telescopic rod 44. At this time, the shielding plate 42 is no longer located at the bottom of the nozzle of the spray box 6, and then the rotating rod 47 is activated. When the motor stops, the nozzle of the spray box 6 can spray the steel bars. After the steel bars are sprayed, the motor corresponding to the rotating rod 47 is restarted, causing the rotating rod 47 to rotate. The rotation of the rotating rod 47 drives the rotating ring 48 to rotate. The semicircular block of the rotating ring 48 rotates without contacting the semicircular block of the moving block 45. At this time, the elastic telescopic rod 44 will drive the moving block 45 and the shielding plate 42 to reset through its own elasticity. This allows the shielding plate 42 to shield the atomizing nozzle of the spray box 6 again, preventing residual rust remover from dripping into the atomizing nozzle of the spray box 6, preventing environmental pollution, reducing rust inhibitor waste, and ensuring that the atomizing nozzle is kept clean when not in use, thus extending the service life of the equipment and improving the stability of the spraying effect.

[0026] like Figures 4-5 As shown, the side of the shielding plate 42 is provided with an anti-pollution device 5 to prevent dirt from contaminating the reinforcing steel bars of the pushing belt 3. The anti-pollution device 5 includes a movable plate 51, the side of which is fixedly connected to the side of the shielding plate 42. A placement plate 52 is fixedly connected to the side of the support base 1. A limit plate 53 is fixedly connected to the bottom of the L-shaped support plate 46. A square fixing rod 54 is fixedly connected to the side of the placement plate 52. The end of the square fixing rod 54 away from the placement plate 52 is fixedly connected to the side of the limit plate 53. A square fixing rod 54 is slidably connected to the outer wall of the square fixing rod 54. A square sliding sleeve 55 is fixedly connected to a connecting plate 56 on its side. The inner wall of the connecting plate 56 is slidably connected to the outer wall of the square fixed rod 54. A cleaning plate 57 is fixedly connected to the top of the square sliding sleeve 55. A semi-circular block is fixed to the side of the moving plate 51. A semi-circular block is fixed to the side of the connecting plate 56 away from the square sliding sleeve 55. The circular surface of the semi-circular block of the connecting plate 56 is located on the movement trajectory of the circular surface of the semi-circular block of the moving plate 51. A spring is provided between the placement plate 52 and the square sliding sleeve 55. The top of the cleaning plate 57 is in contact with the bottom of the push belt 3.

[0027] According to the above structure, each time the shielding plate 42 moves away from the rotating ring 48, it will drive the moving plate 51 to move, so that the semicircular block of the moving plate 51 no longer abuts against the semicircular block of the connecting plate 56. Therefore, the connecting plate 56 will move along the square fixed rod 54 towards the limiting plate 53 under the action of the corresponding spring force through the square sliding sleeve 55. The movement of the square sliding sleeve 55 drives the cleaning plate 57 to move. When the elastic telescopic rod 44 drives the moving block 45 and the shielding plate 42 to reset through its own elastic force, the semicircular block of the moving plate 51 will abut against the semicircular block of the connecting plate 56 again, so that the connecting plate 56 will squeeze the spring corresponding to the square sliding sleeve 55 through the square sliding sleeve 55. This causes the square sliding sleeve 55 to drive the cleaning plate 57 to move back and forth on the surface of the push belt 3 indirectly, removing dirt and residue on the push belt 3, preventing contamination of the steel bar surface, ensuring uniform spraying of rust inhibitor, improving the rust prevention effect of the steel bar, extending the service life of the equipment, and reducing the amount of subsequent cleaning work.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
