Description

Technical Field

[0001] This utility model relates to the technical field of polishing devices, specifically a polishing device for cold-rolled stainless steel coils. Background Technology

[0002] The cold-rolled stainless steel coil polishing equipment is used to polish the surface of cold-rolled stainless steel coils to improve their surface finish.

[0003] A search revealed Chinese Patent Publication No. CN222818608U, which discloses a polishing device for cold-rolled stainless steel coils, relating to the field of polishing technology. The device includes a polishing box and polishing components. A slag collection box is connected to the lower end of the polishing box. Polishing components, which facilitate the adhesion of debris and reduce its impact on the polishing effect, are housed inside the polishing box. The polishing components include a support plate, side-mounted rods, cleaning brushes, and polishing wheels. A side-mounted rod is mounted on the upper side of the support plate, and a cleaning brush is mounted on the side of the side-mounted rod. A polishing wheel is mounted on the end of the support plate. This cold-rolled stainless steel coil polishing device uses six vertically arranged polishing wheels to polish both sides of the cold-rolled stainless steel coil. The polished debris falls directly into the slag collection box, reducing debris residue on the surface of the cold-rolled stainless steel coil and in the polishing box. The side-mounted rods and cleaning brushes promptly remove any remaining debris after polishing to prevent it from affecting subsequent polishing.

[0004] However, in this polishing device, the steel coil is placed in a coil on a tray and looped around the central rod. As the diameter of the steel coil changes as it is discharged, when the diameter of the steel coil is large and exceeds the distance between the two side baffles, the steel coil will rub against the side walls of the side baffles when it enters the polishing box. Over time, this friction will cause the side baffles to wear out and become damaged, reducing the efficiency of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a polishing device for cold-rolled stainless steel coils. This device solves the problem that in polishing devices, steel coils are placed in coils on a tray and fitted onto a central rod. Because the diameter of the steel coil changes as it is discharged, when the diameter is large and exceeds the distance between the side baffles, the coil rubs against the side walls of the baffles upon entering the polishing chamber. Prolonged friction causes wear and damage to the side baffles, reducing the device's efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for cold-rolled stainless steel coils, comprising a polishing box, a base plate fixedly installed on both sides of the lower end of the polishing box, a support plate fixedly installed on the top of each base plate, a sleeve rod rotatably connected to the front side wall of each support plate, a baffle fixedly sleeved to the rear end of each sleeve rod, first rotating rollers symmetrically rotatably connected to the front side wall of each support plate, and the axis between two adjacent first rotating rollers being coaxial with the central axis of the sleeve rod, and a second rotary motor fixedly installed on the rear side wall of each support plate, the output shaft of the second rotary motor being fixedly connected through the support plate and the rear end of the sleeve rod.

[0007] Preferably, a polishing roller is rotatably connected between the upper two side walls of the polishing box. A groove is provided inside the bottom surface of the polishing box, and a movable plate is slidably connected inside the groove. A second rotating roller is rotatably connected at equal intervals inside the top surface of the movable plate. A cylinder is fixedly installed at the bottom of the polishing box. The output shaft of the cylinder is fixedly connected to the bottom of the movable plate through the bottom side wall of the polishing box. The central axis of the movable plate is on the same axis as the central axis of the polishing roller, so that the steel coil entering the polishing box can be moved upward conveniently for tensioning, support and polishing.

[0008] Preferably, a first rotary motor is fixedly installed on the rear side wall of the polishing box. The output shaft of the first rotary motor is fixedly connected to the rear end of the polishing roller through the interior of the side wall of the polishing box. A dust collection box is fixedly installed at the upper end of the polishing box. A dust collection pipe is fixedly installed at the dust collection end of the dust collection box. A connecting pipe is fixedly installed at the front end of the dust collection pipe. Branch pipes are fixedly installed at both ends of the connecting pipe. Strip-shaped dust collection nozzles are fixedly installed between the two side walls at both ends of the polishing box. The bottom of the branch pipe and the lower end of the strip-shaped dust collection nozzle are fixedly connected to the upper end of the strip-shaped dust collection nozzle through the top of the polishing box. The strip-shaped dust collection nozzles are all located above the moving plate, which facilitates dust collection during polishing.

[0009] Preferably, a limiting ring is slidably sleeved on the front end of the sleeve rod, and a threaded tube is fixedly installed on the front side wall of the limiting ring, with the central axis of the threaded tube and the central axis of the limiting ring on the same axis. The threaded tube is threadedly sleeved on the front end of the sleeve rod, thereby facilitating the limiting of the position of the placed steel coil.

[0010] Preferably, sealing plates are fixedly installed on both the front and rear sidewalls of the movable plate, and the sidewalls of the sealing plates are respectively in contact with the two sidewalls inside the polishing box, so as to prevent the generated debris from falling below the movable plate.

[0011] Preferably, the bottom of the polishing box is symmetrically and fixedly equipped with support blocks, which facilitates the support of the polishing box position.

[0012] This utility model provides a polishing device for cold-rolled stainless steel coils. It has the following beneficial effects: This cold-rolled stainless steel coil polishing device, when used, by setting the first rotating rollers between the polishing box and the connecting rod, enables the steel coil to be locked between the adjacent first rotating rollers when it enters the polishing box and moves to the outside of the polishing box. This can conveniently protect the moving steel coil and prevent friction damage. This cold-rolled stainless steel coil polishing device, when in use, by extending the front end of the first rotating roller to the front end of the threaded tube, can effectively prevent the moving steel coil from being completely between the two first rotating rollers, thus strengthening the limitation of the steel coil's position.
