Description

Technical Field

[0001] The utility model specifically relates to a passivation device, in particular to a steel strip surface passivation device. Background Art

[0002] Surface passivation is a critical step in the steel strip production process. It aims to form a protective oxide film or coating on the steel strip's surface to enhance its corrosion resistance and extend its service life. For precision applications such as electronic component packaging and high-end packaging materials, strict control is required over the thickness of the passivation film on the steel strip surface. Excessively thick or thin passivation layers can affect the performance of the final product. For example, an excessively thick passivation film can make subsequent processing difficult, while an excessively thin film may not provide adequate protection.

[0003] However, in the prior art, although there are passivation devices that meet the passivation requirements of steel strips, most of these devices do not have the function of adjusting the thickness of the passivation film and cannot perform detailed processing according to the differences in the passivation liquid, which makes the device limited in controlling the thickness and uniformity of the passivation film. Therefore, it is necessary to design a steel strip surface passivation device that can adjust the thickness of the passivation film. Utility Model Content

[0004] In order to overcome the shortcoming that the existing passivation device cannot control the thickness of the passivation film, the technical problem to be solved is: to provide a steel strip surface passivation device that can adjust the thickness of the passivation film.

[0005] The technical solution is: a steel strip surface passivation device, including a frame, a discharge drum, a coiling drum, a passivation box, a guide rod, a sliding plate, a sponge roller and an L-shaped support rod. The discharge drum and the coiling drum are respectively installed at the head and tail ends of the frame, and a passivation box is provided in the middle of the frame. The outer walls of the frame in the length direction are respectively fixedly connected with L-shaped support rods, and the upper and lower parts of the L-shaped support rods are fixedly connected. The sliding plate is slidably connected to the guide rods, and a sponge roller is provided between the two opposite guide rods. The sponge roller is rotatably connected to the sliding plate.

[0006] As a further preferred solution, a first conveyor roller is rotatably connected to one side of the passivation box, a second conveyor roller is rotatably connected to the middle of the passivation box, the first conveyor roller and the second conveyor roller are arranged in parallel at the bottom of the passivation box, and a third conveyor roller is rotatably connected to the middle of the frame, the third conveyor roller is arranged above the passivation box and is parallel to the second conveyor roller above and below, and the first conveyor roller, the second conveyor roller and the third conveyor roller are used to limit the moving route of the steel strip.

[0007] As a further preferred solution, one end of the screw rod away from the sliding plate is connected to the output shaft of the motor installed on the L-shaped support rod, and the screw rod is threadedly connected to the sliding plate.

[0008] As a further preferred solution, it also includes a mounting frame and a fan. One side of the rack is fixedly connected to the mounting frame, and a group of fans are installed on the upper and lower parts of the mounting frame.

[0009] As a further preferred solution, the scale plate is fixedly connected to the L-shaped support rod, and the scale plate is arranged in the middle of the L-shaped support rod to measure the gap between the upper and lower sponge rollers.

[0010] As a further preferred solution, the unwinding drum, the third conveying roller and the winding drum are on the same horizontal plane.

[0011] The utility model has the following advantages: 1. The utility model can flexibly control the thickness of the passivation film by adjusting the gap between the sponge rollers through the motor-driven screw. This design meets the different requirements of different passivation solutions for the thickness of the passivation film, improving the applicability and flexibility of the equipment.

[0012] 2. The utility model can timely dry the surface of the steel strip by installing multiple sets of fans inside the mounting frame, effectively preventing the steel strip from sticking during the subsequent winding process, and ensuring the quality and production efficiency of the steel strip.

[0013] 3. The utility model can also provide sufficient time for the steel strip to contact with the passivation liquid through the distribution design of the delivery roller I and the second delivery roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment: A steel strip surface passivation device, such as Figure 1 and Figure 3 As shown, it includes a frame 1, a discharge drum 2, a winding drum 3, a passivation box 4, a guide rod 10, a sliding plate 11, a sponge roller 12 and an L-shaped support rod 16. The discharge drum 2 and the winding drum 3 are respectively installed at the head and tail ends of the frame 1, and the passivation box 4 is provided in the middle of the frame 1. The outer walls of the frame 1 in the longitudinal direction are respectively fixedly connected with L-shaped support rods 16, and the upper and lower parts of the L-shaped support rods 16 are fixedly connected. The sliding plate 11 is slidably connected to the guide rods 10, and a sponge roller 12 is provided between the two opposite guide rods 10. The sponge roller 12 is rotatably connected to the sliding plate 11.

[0021] like Figure 1 and Figure 2 As shown, a first conveyor roller 5 is rotatably connected to one side of the passivation box 4, a second conveyor roller 6 is rotatably connected to the middle of the passivation box 4, the first conveyor roller 5 and the second conveyor roller 6 are arranged in parallel at the bottom of the passivation box 4, and a third conveyor roller 7 is rotatably connected to the middle of the frame 1, the third conveyor roller 7 is arranged above the passivation box 4 and is parallel to the second conveyor roller 6 above and below, the first conveyor roller 5, the second conveyor roller 6 and the third conveyor roller 7 are used to limit the moving route of the steel strip, and provide sufficient time for the steel strip to contact with the passivation liquid.

[0022] like Figure 3 As shown, one end of the screw rod 9 away from the sliding plate 11 is connected to the output shaft of the motor 8 mounted on the L-shaped support rod 16, and the screw rod 9 is threadedly connected to the sliding plate 11. Here, the motor 8 drives the screw rod 9 to rotate, and the screw rod 9 drives the sliding plate 11 to move up and down.

[0023] like Figure 4 As shown, it also includes a mounting frame 13 and a fan 14. The mounting frame 13 is fixedly connected to one side of the frame 1, and a group of fans 14 are installed on the upper and lower parts of the mounting frame 13. Here, the fan 14 is used to air dry the surface of the steel strip to prevent the steel strip from sticking during the subsequent winding process.

[0024] like Figure 1As shown, the scale plate 15 is fixedly connected to the L-shaped support rod 16, and the scale plate 15 is set in the middle of the L-shaped support rod 16. Here, the gap between the upper and lower sponge rollers 12 can be measured by the scale marked on the scale plate 15, and the movement of the sponge roller 12 can be precisely controlled.

[0025] When the surface of the steel strip needs to be passivated, this device can be used. The steel strip raw material is placed on the discharge drum 2, and then the steel strip is pulled so that the steel strip passes under the first conveyor roller 5 and the second conveyor roller 6 inside the passivation box 4, and then the steel strip is passed around the left side of the third conveyor roller 7. After that, the steel strip with passivation liquid is inserted into the gap between the two sponge rollers 12, and the passivation liquid is evenly covered on the surface of the steel strip through the sponge rollers 12, while the excess passivation liquid on the surface of the steel strip is cleaned. When it is necessary to control the thickness of the passivation film for different passivation liquids, the gap between the sponge rollers 12 can be adjusted to meet the needs. When it is necessary to thicken the passivation film on the surface of the steel strip, the motor 8 is started, and the motor 8 drives the screw 9 to rotate counterclockwise. The screw 9 drives the sliding plate 11 to move toward the motor 8, thereby driving the two sponge rollers 12 to separate from each other, increasing the gap between the two sponge rollers 12, so that the two sponge rollers 12 do not squeeze the steel strip too much, reducing the amount of passivation liquid cleaned on the surface of the steel strip, thereby forming a thickened passivation film. When a thinner passivation film is required, the motor 8 drives the screw 9 to rotate clockwise, which drives the sliding plate 11 closer to each other, driving the two sponge rollers 12 closer to each other, thereby reducing the gap between the two sponge rollers 12. The two sponge rollers 12 further squeeze the steel strip and scrape the passivation liquid on the steel strip surface, thus forming a thinner passivation film. After the passivation film thickness is processed, the steel strip enters the mounting frame 13, and the fan 14 air-dries the steel strip surface. The air-dried steel strip is then reeled onto the coil drum 3, completing the passivation process of the steel strip.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
