Description

Technical Field

[0001] The utility model relates to the technical field of steel coil spraying devices, in particular to a spraying anti-rust device. Background Art

[0002] Steel coil is a common metal product. It is usually a long strip of steel made by hot rolling or cold rolling process and rolled into a larger roll. The spray anti-rust device is a device used to prevent metal materials (such as steel coils) from rusting. It usually consists of spray equipment, anti-rust paint and corresponding control system.

[0003] In some existing spray anti-rust devices, the width of the spray mechanism is usually the same as the width of the steel coil. When spraying steel coils of different widths, other types of spray devices need to be used, which is less practical. In addition, when such spray devices spray the surface of the steel coil through the nozzle, some positions on the surface of the steel coil are prone to not being sprayed, and re-spraying is required, which reduces work efficiency.

[0004] Therefore, those skilled in the art provide a spray anti-rust device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a spray anti-rust device is proposed. By setting a first waterproof cloth, when spraying steel coils of different widths, the overall width of the water outlet is aligned with the width of the steel coil, and there is no need to use other types of spray devices, thereby improving practicality. By setting a drying mechanism, the anti-rust water can be evenly distributed on the surface of the steel coil after spraying, and the evaporation of the anti-rust water is accelerated, thereby improving work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spraying anti-rust device, comprising a conveyor belt, a spraying mechanism, a drying mechanism and a steel coil, the spraying mechanism comprising a first box body, two sliding grooves, two second screw rods and four sliders, the outer end faces of the two second screw rods are fixedly sleeved with second sprockets, a second chain is meshed between the two second sprockets, two first waterproof cloths are slidably arranged on the upper side and the lower side inner wall of the first box body, and reset springs are fixedly arranged between the four first waterproof cloths;

[0023] 2. The utility model proposes a spray anti-rust device, which controls the distance between the multiple rotating columns on the upper side and the lower side through an electric telescopic rod according to the thickness of the steel coil. When the steel coil slides between the multiple rotating columns, the multiple rotating columns are driven to rotate, so that the anti-rust water on the surface of the steel coil is distributed more evenly. When one end of the steel coil slides out from between the rotating columns, the fan accelerates the evaporation of the anti-rust water on the surface of the steel coil. By setting a drying mechanism, the anti-rust water can be evenly distributed on the surface of the steel coil after spraying, and the evaporation of the anti-rust water is accelerated, thereby improving work efficiency.

There is no need for manual spraying, which is more convenient.

[0035] A first screw rod 9 is rotatably arranged at the lower side between the end faces of one side of the conveyor belt 1. A first sprocket wheel 10 is fixedly sleeved on the front side of the first screw rod 9 and one of the outer end faces of the lower sides of the two second screw rods 203.

Therefore, the steel coil 4 can be placed on the surface of the conveyor belt 1 first, and then the rotating motor 5 is turned on to control the two positioning plates 6 to fit with the end surface of the steel coil 4. When the two positioning plates 6 fit with the end surface of the steel coil 4, the distance between the first waterproof cloths 207 in the two sliding grooves 202 is the same as the width of the steel coil 4.

[0036] The drying mechanism 3 includes a second box body 301, a spraying slot 302, an electric telescopic rod 306, a drying slot 307 and a plurality of fans 309. A U-shaped plate 303 is slidably arranged between the front and rear inner walls of the spraying slot 302. A plurality of rotating columns 304 are rotatably arranged on the lower sides between the spraying slot 302 and the front and rear inner walls of the U-shaped plate 303. The outer end surfaces of the plurality of rotating columns 304 are fixedly sleeved with a second waterproof cloth 305. The spraying slot 302 is arranged on the inner wall of one side of the second box body 301. The electric telescopic rod 306 is embedded on one side of the upper end surface of the second box body 301. The output end of the electric telescopic rod 306 is fixedly connected to the middle position of the upper end surface of the U-shaped plate 303. The drying slot 307 is arranged on the inner wall of the other side of the second box body 301. A plurality of fans 309 are respectively fixedly arranged on the upper and lower inner walls of the drying slot 307.

When the steel coil 4 enters between the upper rotating column 304 and the lower rotating column 304, the multiple rotating columns 304 will squeeze the steel coil 4, so that the anti-rust water can more thoroughly penetrate and wet the surface of the steel coil 4 during the contact process, and the steel coil 4 will continue to move to one side driven by the conveyor belt 1, and the contact between the steel coil 4 and the rotating column 304 will drive the multiple rotating columns 304 to rotate, so that the angle and direction of the anti-rust water spraying will change. At this time, the anti-rust water will more fully cover the surface of the steel coil 4, thereby achieving a more uniform distribution of the anti-rust water.

[0038] Working principle: manually place the steel coil 4 on the surface of the conveyor belt 1, then turn on the rotating motor 5, which drives the first screw rod 9 and the second screw rod 203 to rotate, so that the two positioning plates 6 are moved closer to the front and rear end faces of the steel coil 4. When the two positioning plates 6 are in contact with the end faces of the steel coil 4, turn off the rotating motor 5, then turn on the electric telescopic rod 306, and adjust the position of the U-shaped plate 303 according to the thickness of the steel coil 4. At this time, turn on the conveyor belt 1 and multiple fans 309. When the conveyor belt 1 drives When one end of the steel coil 4 on the surface slides into the first box body 201, the water pump 8 is turned on, and the water pump 8 sprays the anti-rust water in the water tank 7 to the surface of the steel coil 4 through the pipe. When one end of the steel coil 4 leaves the first box body 201 and enters the second box body 301, the multiple rotating columns 304 squeeze the surface of the steel coil 4, and the steel coil 4 drives the multiple rotating columns 304 to rotate during the movement. When one end of the steel coil 4 enters the drying tank 307, the fan 309 blows the wind to the surface of the steel coil 4.
