The spring is used to facilitate the push of the slider and the baffle to reset. By setting a torsion spring, the baffle can be easily rotated to reset horizontally. Attached Figure Description

[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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a stainless steel coil unwinding device includes a frame 11. A rotating shaft 12 is rotatably connected to the top of the frame 11. An unwinding roller 13 is fixedly connected to the end of the rotating shaft 12. One end of the unwinding roller 13 has a limiting ring. A groove 14 is formed at the end of the unwinding roller 13 away from the limiting ring. A slider 15 is slidably connected in the groove 14. A shaft 16 is rotatably connected to the middle of the slider 15. A support 18 is fixedly connected to the shaft 16. A baffle 19 is fixedly connected to the top of the support 18. A rope wheel 17 is fixedly connected to the middle of the shaft 16. A pull rope 25 is fixedly connected to the rope wheel 17. The frame 11 is provided with a tightening assembly capable of pulling the pull rope 25; the tightening assembly includes a hydraulic cylinder 21, a pull rod 23, and a connecting arm 22. The hydraulic cylinder 21 is fixedly connected to the frame 11, the connecting arm 22 is fixedly connected to the output end of the hydraulic cylinder 21, the pull rod 23 is rotatably connected to the top end of the connecting arm 22, the rotating shaft 12 has a sliding hole inside, the end of the sliding hole has multiple through slots 24, the pull rod 23 is slidably connected to the sliding slots 14, the unwinding roller 13 has multiple rope holes 26 inside, the pull rope 25 passes through the rope holes 26 and its end is fixedly connected to the pull rod 23;

[0024] In the initial state of use, the baffle 19 is placed horizontally. The operator passes the steel coil through the baffle 19 and places it on the unwinding roller 13. After placement, the hydraulic cylinder 21 is activated, which pulls the connecting arm 22 and the pull rod 23 to move. The connecting arm 22 and the pull rod 23 are rotatably connected. The pull rod 23 moves and pulls the pull rope 25. The pull rope 25 is wound around the rope wheel 17. The pull rope 25 pulls the rope wheel 17, the shaft 16, the baffle 19 and the support 18 to rotate, thereby causing the baffle 19 to unfold. The baffle 19 is used to limit the steel coil, and the slider 15 can slide in the slide groove 14. This allows for convenient limiting of steel coils of different widths. With the above settings, the steel coil can be automatically limited and prevented from falling off, making it convenient for operators to use and reducing the safety hazards caused by manual installation of the baffle 19.

[0025] Furthermore, such as Figure 4 As shown, a first pulley 31 is rotatably connected to one end of the rope hole 26 near the rotating shaft 12, and a second pulley 32 is rotatably connected inside the through groove 24; a spring 4 is fixedly connected to the inner wall of the slide groove 14, and the end of the spring 4 is fixedly connected to the side wall of the slider 15; a torsion spring is installed at the rotatable connection between the rotating shaft 12 and the slider 15.

[0026] In use, the first pulley 31 and the second pulley 32 are used to guide the pull rope 25 and reduce the sliding of the pull rope 25 and the friction between the end of the through groove 24 and the rope hole 26, thereby reducing the wear on the pull rope 25. The spring 4 is used to facilitate the push of the slider 15 and the baffle 19 to reset. The torsion spring is provided to facilitate the rotation of the baffle 19 to reset horizontally.

[0027] Furthermore, such as Figure 1-5 As shown, a roller shaft 51 is rotatably connected to the side of the baffle 19. A through groove 52 is provided at the corresponding position of the baffle 19 and the roller shaft 51, and the side of the roller shaft 51 passes through the through groove 52. In use, the roller shaft 51 passes through its through groove 52 and can rotate accordingly. The roller shaft 51 is used to contact the baffle 19 instead of the steel coil. When relative sliding friction occurs between the steel coil and the baffle 19, the friction between the surface of the steel coil and the side wall of the baffle 19 can be reduced, thereby protecting it and reducing wear.

[0028] Furthermore, such as Figure 4 As shown, a seat 61 is fixedly connected to one end of the unwinding roller 13 away from the limiting ring. A buffer pad 62 is fixedly connected to the side of the seat 61 near the slide groove 14. The buffer pad 62 is located on the side of the slide groove 14. In use, the seat 61 is used to limit the slider 15, and the rubber buffer pad 62 is used to buffer the slider 15 and protect it after the slider 15 is reset.

[0029] Furthermore, such as Figure 1-5 As shown, the end of the baffle 19 is arranged in a triangular structure. When in use, the end of the baffle 19 is arranged in a triangular structure, and after the baffle 19 is laid flat, it can be conveniently inserted into the stainless steel roll.

[0030] Working principle: In the initial state, the baffle 19 is placed horizontally. The operator passes the steel coil through the baffle 19 and places it on the unwinding roller 13. After placement, the hydraulic cylinder 21 is activated, pulling the connecting arm 22 and the pull rod 23 to move. The connecting arm 22 and the pull rod 23 are rotatably connected. The pull rod 23 moves and pulls the pull rope 25, which is wound around the rope wheel 17. The pull rope 25 pulls the rope wheel 17, the shaft 16, the baffle 19, and the support 18 to rotate, thereby unfolding the baffle 19. The baffle 19 limits the steel coil, and the slider 15 can slide within the groove 14, which facilitates the limiting of steel coils of different widths. With the above settings, the steel coil can be automatically limited and prevented from detaching, making it convenient for operators to use and reducing the safety hazards caused by manual installation of the baffle 19. The first pulley 31 is also included. The second pulley 32 can be used to guide the pull rope 25 and reduce the sliding of the pull rope 25 and the friction between the end of the through groove 24 and the rope hole 26, thereby reducing the wear on the pull rope 25. The spring 4 is used to facilitate the push of the slider 15 and the baffle 19 to reset. The torsion spring can facilitate the horizontal reset of the baffle 19. In use, the roller 51 passes through its through groove 52 and can rotate accordingly. The roller 51 contacts the baffle 19 instead of the steel coil. When relative sliding friction occurs between the steel coil and the baffle 19, the friction between the surface of the steel coil and the side wall of the baffle 19 can be reduced, thereby protecting them and reducing wear. The seat 61 can limit the slider 15. The rubber buffer pad 62 can buffer the slider 15 and protect it after the slider 15 is reset.
