Description

Technical Field

[0001] This utility model relates to a steel surface polishing device, and pertains to the field of steel polishing technology. Background Technology

[0002] Steel, as an important metallic material, is widely used in various industries. Polishing is a crucial step in steel processing, aiming to remove burrs, oxides, and dirt from the surface, improving surface quality, aesthetics, and corrosion resistance. In practice, steel plates often require polishing on both sides. A single polishing roller is typically used to polish the upper surface of the plate. However, this method necessitates frequent reloading and re-polishing, severely impacting the efficiency of the polishing process. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a steel surface polishing device to solve the problems existing in the prior art. The specific technical solution is as follows:

[0004] A steel surface polishing device includes a housing with an inlet and an outlet located in the middle of the front and rear sides of the housing. A feeding device is installed inside the housing. An upper polishing roller and a lower polishing roller are symmetrically arranged inside the housing. The upper and lower polishing rollers are rotatably connected to a movable frame, with one end passing through the movable frame and connected to a first motor fixedly mounted on the movable frame. A limiting sleeve is fixedly connected to the middle of the movable frame. A telescopic rod of a cylinder is slidably connected inside the limiting sleeve. A buffer spring is provided between the telescopic rod and the movable frame. The cylinder is fixedly connected to a fixed frame.

[0005] Preferably, the movable frame is provided with a guide channel, the guide channel is connected to a water inlet pipe, the water inlet pipe is connected to a water tank set on the box body, a water pump is provided on the water inlet pipe, and the movable frame is provided with a plurality of water spray nozzles facing the upper polishing roller or the lower polishing roller and communicating with the guide channel.

[0006] Preferably, the feeding device includes a plurality of guide rollers rotatably connected to the housing on both sides of the upper polishing roller, and a plurality of conveying rollers rotatably connected to the housing on both sides of the lower polishing roller, wherein the gap between the conveying rollers and the guide rollers is used to convey steel.

[0007] Furthermore, positioning plates are symmetrically arranged between the conveying rollers and guide rollers on both sides of the upper polishing roller, and the telescopic rod of the electric push rod is fixedly connected to the middle of the outer side of the positioning plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-2As shown, a steel surface polishing device includes a housing 1. The housing 1 has an inlet 2 and an outlet 3 located in the middle of its front and rear sides, respectively. A feeding device for conveying steel plates is installed inside the housing 1. The inlet 2 and outlet 3 correspond to the front and rear ends of the feeding device. An upper polishing roller 4 and a lower polishing roller 5 are symmetrically arranged inside the housing 1. The upper polishing roller 4 and the lower polishing roller 5 are rotatably connected to a movable frame 6, with one end passing through the movable frame 6 and connected to a first motor 7 fixedly mounted on the movable frame 6. A limiting sleeve 8 is fixedly connected to the middle of the movable frame 6. A telescopic rod of a cylinder 9 is slidably connected inside the limiting sleeve 8. A buffer spring 10 is provided between the telescopic rod and the movable frame 6. The cylinder 9 is fixedly connected to a fixed frame 21. The cylinders 9 installed at the top and bottom of the housing 1 operate simultaneously, causing the moving frame 6 corresponding to the upper polishing roller 4 to move down and the moving frame 6 corresponding to the lower polishing roller 5 to move up, leaving only a gap between them for the steel plate to pass through. When the steel plate is conveyed to this gap, the upper polishing roller 4 and the lower polishing roller 5 polish the front and back of the steel plate. The buffer spring 10 acts as a buffer, leaving room for movement between the upper polishing roller 4 and the lower polishing roller 5 and the steel plate, thus avoiding rigid collisions.

[0016] The movable frame 6 is equipped with a guide channel 11, which is connected to a water inlet pipe 12. The water inlet pipe 12 is connected to a water tank 13 mounted on the housing 1. A water pump 14 is mounted on the water inlet pipe 12. The movable frame 6 has multiple water spray nozzles that face the upper polishing roller 4 or the lower polishing roller 5 and are connected to the guide channel 11. The water sprayed from the nozzles falls directly onto the upper polishing roller 4 and the lower polishing roller 5. When the upper polishing roller 4 and the lower polishing roller 5 come into contact with the steel plate during polishing, they can achieve a cooling effect.

[0017] The feeding device includes multiple guide rollers 15 located on both sides of the upper polishing roller 4 and rotatably connected to the housing 1, and multiple conveying rollers 16 located on both sides of the lower polishing roller 5 and rotatably connected to the housing 1. The gap between the conveying rollers 16 and the guide rollers 15 is used to convey steel. The conveying rollers 16 are powered by a drive mechanism, such as a second motor. The specific principle and transmission relationship are existing technologies and will not be described in detail here.

[0018] Positioning plates 17 are symmetrically arranged between the conveying rollers 16 and guide rollers 15 on both sides of the upper polishing roller 4. A telescopic rod of an electric push rod 18 is fixedly connected to the center of the outer side of the positioning plate 17, and the electric push rod body is installed on the outside of the housing 1. The bottom of the positioning plate 17 has multiple arc-shaped recesses corresponding to the conveying rollers 16, and these recesses are set close to the conveying rollers 16. The positioning plate 17 is located between the guide rollers 15 and the conveying rollers 16, occupying little space. By adjusting the position of the positioning plate 17, steel plates of different sizes can be polished, avoiding the problem of uncertain positioning when the steel plate is too small, which would affect the polishing effect. This invention, through the adjustment of the position of the positioning plate 17, ensures that the steel plate is precisely positioned between the positioning plates 17, preventing misalignment during polishing.

[0019] An upper air pipe 19 is provided on the top wall of the housing 1 between the upper polishing roller 4 and the discharge port 3, and a lower air pipe 20 is provided on the bottom wall of the housing 1 between the lower polishing roller 5 and the discharge port 3. The upper air pipe 19 and the lower air pipe 20 are connected to an external blower. The air pipes are set near the discharge port 3 to blow away debris from the upper and lower surfaces of the polished steel plate, and to dry the moisture on the surface.

[0020] The working principle of this utility model is as follows:

[0021] The steel plate to be polished is fed into the feed inlet 2 and conveyed by the conveying roller 16. Simultaneously, the guide roller 15 presses the steel plate, fixing it vertically. The positions of the upper polishing roller 4 and lower polishing roller 5 are pre-adjusted to allow the steel plate to pass through the gap. As the steel plate passes through this gap, it exerts pressure on the rollers, which is cushioned by the buffer spring 10. The rollers adhere well to both sides of the steel plate, resulting in a good polishing effect. Water sprayed onto the rollers via the moving frame 6 cools them during polishing. A blower near the outlet 3 dries the upper and lower surfaces of the steel plate, ensuring a clean and tidy finish when exiting the outlet.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
