Technical Field
[0001] This utility model relates to the field of polishing equipment, and in particular to a surface polishing equipment for fireproof roller shutter doors. Background Technology
[0002] Fire-resistant roller shutter panels are a major component of fire-resistant roller shutters. They are typically made of non-combustible materials such as steel and inorganic fibers, and possess excellent fire-resistant and heat-insulating properties. For a certain period, together with the frame, they can meet the requirements for fire resistance stability and integrity, effectively preventing the spread of fire. In the event of a fire, the fire-resistant roller shutter panels can quickly descend, forming a robust fire barrier to protect the building structure and buy valuable time for evacuation and firefighting. Fire-resistant roller shutter panels are widely used in shopping malls, supermarkets, industrial plants, underground garages, high-rise buildings, and other places, and are an important fire-resistant partition in modern buildings.
[0003] In the prior art, there is a Chinese utility model patent with publication number "CN213106255U" and patent name "A Polishing Device for High-Speed Rolling Shutter Door Production". This patent describes a technical solution such as "a polishing machine and a worktable located below the polishing wheel of the polishing machine, the worktable is provided with several one-way wheels, the one-way wheels are provided with anti-wear rings, the worktable is provided with a connecting plate, the side plate of the connecting plate is provided with a connecting rotating hole, the side of the one-way wheel is symmetrically provided with a connecting rotating shaft, the connecting rotating shaft is rotatably connected to the connecting rotating hole, the worktable is symmetrically provided with baffles, the one-way wheels are located between the baffles, the worktable is provided with a sliding groove, the baffle is provided with a slider, and the sliding groove is slidably connected to the slider".
[0004] However, this device has significant limitations when practically applied to polishing the surface of fireproof rolling shutter doors. Firstly, both loading and unloading of the shutter panels rely on manual labor, increasing labor costs and leading to instability and inefficiency.

[0008] A fireproof roller shutter door surface polishing device includes a first roller conveyor belt and a second roller conveyor belt. A polishing mechanism is provided between the first and second roller conveyor belts. The polishing mechanism includes a polishing table, a first concave seat, a lead screw, a servo motor, a first electromagnetic chuck, a first cylinder, a movable plate, a polishing roller, and a rotary motor. The polishing table is fixedly connected between the first and second roller conveyor belts, and the first concave seat is fixedly connected to one side of the top surface of the polishing table.

[0009] Preferably, the top surface of the polishing table is provided with a groove, and the inner walls of the groove are respectively fixedly installed with first guide strips. The two side walls of the polishing table are also respectively provided with first rotating holes communicating with the groove.
[0010] Preferably, a first rotating rod is fixedly installed at each of the left and right ends of the lead screw, and the first rotating rod is movably installed in the first rotating hole. The servo motor is fixedly installed on the left side wall of the polishing table, and the output end of the servo motor is fixedly installed together with the first rotating rod at the left end. A connecting plate is fixedly installed on the left side of the bottom surface of the first electromagnetic chuck, and a screw hole is opened on the side wall of the connecting plate and threadedly connected to the lead screw through the screw hole. A first guide groove corresponding to the first guide bar is also opened on both sides of the connecting plate.
[0011] Preferably, an inverted first concave seat is fixedly installed on the right side of the top surface of the polishing table, and vertical side openings are respectively opened on the two side walls of the first concave seat, and second guide bars are fixedly installed on the two side walls inside the vertical side openings.
[0012] Preferably, the first cylinder is fixedly installed on the top surface of the first concave seat, and a movable plate is fixedly installed on the output end of the first cylinder.

[0021] 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.
[0022] like Figure 1 - Figure 4 As shown, a surface polishing device for fireproof roller shutter doors includes a first roller conveyor belt 1 and a second roller conveyor belt 2. A polishing mechanism 3 is provided between the first roller conveyor belt 1 and the second roller conveyor belt 2. The polishing mechanism 3 includes a polishing table 4, a first concave seat 8, a lead screw 11, a servo motor 13, a first electromagnetic chuck 14, a first cylinder 18, a movable plate 19, a polishing roller 23, and a rotary motor 25. The polishing table 4 is fixedly connected between the first roller conveyor belt 1 and the second roller conveyor belt 2, and the first concave seat 8 is fixedly connected to one side of the top surface of the polishing table 4. The lead screw 11 is connected to the first rotating rods at both ends. 12 is movably connected to the top surface of the polishing table 4, and one end of the first rotating rod 12 is fixedly connected to the output end of the servo motor 13 on the side wall of the polishing table 4. The first electromagnetic chuck 14 is movably connected to the lead screw 11 through the connecting plate 15 on one side of the bottom surface. The first cylinder 18 is fixedly connected to the top surface of the first concave seat 8, and the movable plate 19 is fixedly connected to the output end of the first concave seat 8. The polishing roller 23 is movably connected between the bottom side plates 21 symmetrical to the bottom surface of the movable plate 19 through the second rotating rods 24 at both ends, and one end of the second rotating rod 24 is fixedly connected to the output end of the rotary motor 25 on the outer side wall of one side of the bottom side plate 21.
[0023] like Figure 2 As shown, the top surface of the polishing table 4 is provided with a groove 5, which provides space for the movement of the connecting plate 15. The inner walls of the groove 5 are respectively fixedly installed with first guide bars 6, which guide the movement of the connecting plate 15. The two side walls of the polishing table 4 are also respectively provided with first rotating holes 7 that communicate with the groove 5. The first rotating holes 7 are used to cooperate with the first rotating rod 12 to realize the rotation operation.
[0024] like Figure 4 As shown, first rotating rods 12 are fixedly installed at the left and right ends of the lead screw 11, and the first rotating rods 12 are movably installed in the first rotating hole 7. The servo motor 13 is fixedly installed on the left side wall of the polishing table 4, and the output end of the servo motor 13 is fixedly installed together with the first rotating rod 12 at the left end. A connecting plate 15 is fixedly installed on the left side of the bottom surface of the first electromagnetic chuck 14, and a screw hole 16 is opened on the side wall of the connecting plate 15 and threadedly connected to the lead screw 11 through the screw hole 16. The two sides of the connecting plate 15 are also respectively opened with the first guide bar 6. The first guide groove 17 is used to guide the curtain panel to the top surface of the first electromagnetic chuck 14. The first electromagnetic chuck 14 can use the principle of electromagnetic attraction to fix the curtain panel and prevent it from shifting during processing. The servo motor 13 is turned on to drive the output end to rotate the lead screw 11 through the first rotating rod 12. This allows the first electromagnetic chuck 14 to move to the right along the lead screw 11 and the first guide bar 6 through the screw hole 16 and the first guide groove 17 on the bottom connecting plate 15. This allows the curtain panel to move automatically through the polishing roller 23 for surface polishing.
[0025] like Figure 3 As shown, an inverted first concave seat 8 is fixedly installed on the right side of the top surface of the polishing table 4, and vertical side openings 9 are respectively opened on the two side walls of the first concave seat 8. The vertical side openings 9 provide space for the movement of the movable plate 19. The second guide strips 10 are fixedly installed on the two inner side walls of the vertical side openings 9, and the second guide strips 10 provide guidance for the movement of the movable plate 19.
[0026] like Figure 4As shown, the first cylinder 18 is fixedly installed on the top surface of the first concave seat 8, and a movable plate 19 is fixedly installed on the output end of the first cylinder 18. Second guide grooves 20 corresponding to the second guide strip 10 are respectively opened on the two side walls of the movable plate 19. A set of symmetrical bottom side plates 21 are also fixedly installed on the bottom surface of the movable plate 19. Second rotating holes 22 are opened on the side walls of the bottom side plates 21. Second rotating rods 24 are fixedly installed at the front and rear ends of the polishing roller 23, and the second rotating rods 24 are movably installed within the second rotating holes 22. The rotary motor 25 is fixedly mounted... Installed on the outer wall of the front bottom side plate 21, and the output end of the rotary motor 25 is fixedly installed together with the second rotating rod 24 at the front end, the first cylinder 18 is turned on to drive the output end to push the movable plate 19 downward, so that the movable plate 19 moves along the second guide bar 10 through the second guide groove 20 in the vertical side opening 9. The height of the polishing roller 23 can be adjusted according to the thickness of the curtain panel. After the polishing roller 23 contacts the surface of the curtain panel, the second rotating rod 24 is turned on to drive the output end to drive the polishing roller 23 to rotate, so as to polish the surface of the curtain panel passing below.
[0027] like Figure 1 As shown, a set of symmetrically inverted second concave seats 26 are also fixedly installed on the top surface of the second roller conveyor belt 2, and a second cylinder 27 is fixedly installed on the top surface of the second concave seat 26. A second electromagnetic chuck 28 is fixedly installed on the output end of the symmetrical second cylinder 27. After the curtain panel is processed, the second cylinder 27 can be turned on to push the second electromagnetic chuck 28 to magnetically attract the curtain panel, and the magnetic curtain panel is lifted and placed on the second roller conveyor belt 2 to move to the next processing step, which facilitates the automatic unloading operation of the curtain panel. The first electromagnetic chuck 14 and the second electromagnetic chuck 28 are both long table shapes to adapt to the polishing table 4 and the curtain panel.
[0028] The specific polishing principle and process of fireproof roller shutter doors through the coordinated use of the first roller conveyor belt 1, the second roller conveyor belt 2, and the polishing mechanism 3 are as follows:
[0029] After the first roller conveyor belt 1 transports the curtain panel of the fireproof roller shutter door that needs polishing to the first electromagnetic chuck 14, the switch of the first electromagnetic chuck 14 can be turned on to energize it. This energizes the first electromagnetic chuck 14, generating a magnetic field that magnetically holds the curtain panel on the top surface, preventing displacement during polishing and affecting the polishing effect. Then, the servo motor 13 installed on the left side wall of the polishing table 4 is turned on. The servo motor 13 drives the first rotating rod 12 to rotate within the first rotating hole 7, causing the first rotating rod 12 to drive the lead screw 11 to rotate. This allows the connecting plate 15 to pass through the screw hole 16 on the side wall and the first guide groove 17 on both sides, following the groove 5 on the top surface of the polishing table 4 along the lead screw 11 and the first guide bar 6. Moving inward to the right, the connecting plate 15 will drive the first electromagnetic chuck 14 to move synchronously to the right until the curtain plate magnetically fixed on the top surface of the first electromagnetic chuck 14 is placed below the polishing roller 23, at which point the movement stops. The first cylinder 18 mounted on the top surface of the first concave seat 8 is then activated. The first cylinder 18 will drive the output end to push the movable plate 19 downward. The movable plate 19 will move downward through the second guide grooves 20 on both sides along the second guide bar 10 within the vertical side openings 9 on both sides of the first concave seat 8 until the polishing roller 23 contacts the curtain plate surface according to the curtain plate thickness. Then, the rotary motor 25 will be activated to drive the output end to rotate the second rotating rod 24 within the second rotating hole 22 on the side wall of the bottom side plate 21. The second rotating rod 24 will then drive the polishing roller 23... The curtain panel rotates and polishes its surface during this process. The first electromagnetic chuck 14 continuously moves the curtain panel to the right, ensuring it is fully polished as it passes under the polishing roller 23. After polishing, the first electromagnetic chuck 14 moves the polished panel above the second roller conveyor belt 2. Simultaneously, the switch is turned off, releasing the magnetic attraction of the first electromagnetic chuck 14 and activating the second cylinder 27 on the top surface of the second concave seat 26. The second cylinder 27 pushes the second electromagnetic chuck 28 downwards. Once the second electromagnetic chuck 28 contacts the polished curtain panel on the top surface of the first electromagnetic chuck 14, the switch is turned on. The second electromagnetic chuck 28 is energized to magnetically attract the curtain panel. After attraction, the second cylinder 27 drives the second electromagnetic chuck 28 upward to remove the polished curtain panel from the first electromagnetic chuck 14. During this process, the rotary motor 25 stops, and the output end of the first cylinder 18 drives the polishing roller 23 upward back to its original position via the movable plate 19. Simultaneously, driven by the servo motor 13, the first electromagnetic chuck 14 moves to the left back to its original position to prepare for the next polishing of the curtain panel. After the first electromagnetic chuck 14 has completely moved away from under the second electromagnetic chuck 28, the second cylinder 27 drives the output end again to push the second electromagnetic chuck 28 downward. Once the curtain panel contacts the second roller conveyor belt 2, the switch is turned off, the curtain panel is no longer magnetically attracted, and the curtain panel moves upward.To achieve automated material feeding, the polished curtain panel is then conveyed to the next processing step via the second roller conveyor belt 2. This system enables automated feeding, surface polishing, and unloading of fireproof roller shutter curtain panels, eliminating the need for manual operation. It is simple to operate, saves significant time and effort, reduces the workload of workers, and improves work efficiency. It is also suitable for polishing the surface of fireproof roller shutter panels with ferromagnetic materials.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
