Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, and specifically, to a clamping mechanism for a slitting machine that is convenient for adjustment. Background Art

[0002] A slitting machine, also known as a slitting line, is used to uncoil, slit, and rewind a metal coil into a strip coil of the required width. It is applicable to processing various metal materials such as cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, and those with surface coating.

[0003] After retrieval, an adjustable clamping device for a slitting machine described in the patent with the publication number CN218311160U includes a support plate arranged on the main body of the slitting machine. Installation plates are provided at both ends of the support plate, and a cover plate is provided on the top of the support plate. A pressing plate is arranged inside the cover plate, and the pressing plate is connected to the inner wall of the cover plate through a spring. Locking mechanisms are provided at both ends of the cover plate; a first rotating shaft and a second rotating shaft are arranged between the support plates. Mounting openings are provided on the support plates at both ends of the first rotating shaft, and an installation tube rotatably connected to the first rotating shaft is arranged inside the mounting openings. A screw rod is arranged on one side of the installation tube, and a nut seat is connected to the screw rod. The nut seat is connected to the installation tube; a driving mechanism for driving the screw rod is arranged inside the support plate. In this utility model, by providing the cover plate and using the elastic force of the spring, the problem of unstable clamping of the strip steel is avoided. By providing the screw rod, when the screw rod rotates, the height of the installation tube and the first rotating shaft can be adjusted to adapt to the thickness of the strip steel.

[0004] However, the above-mentioned clamping mechanism of the slitting machine still has the following problems: The clamping mechanism adjusts the height of the first rotating shaft by rotating the screw rods on both sides in sequence. However, it is inconvenient for this clamping mechanism to simultaneously rotate and adjust the screw rods on both sides, resulting in different heights on both sides of the first rotating shaft after adjustment. Moreover, when this clamping mechanism clamps strip steels with different widths, it is inconvenient to limit both sides of the strip steel, resulting in lateral displacement of the strip steel during the rewinding process, thereby affecting the cutting accuracy of the strip steel. Summary of the Utility Model

[0005] The utility model provides a clamping mechanism for a slitting machine that is convenient for adjustment, which solves the problems in the prior art that it is inconvenient to synchronously adjust the heights of both ends of the rotating shaft and it is inconvenient to limit both sides of the strip steel, resulting in lateral displacement.

[0013] In the present utility model, the driving assembly can synchronously rotate and adjust the threaded rods inside the two support seats, so that the threaded rods rotate synchronously and perform threaded transmission with the threaded sleeves, enabling precise adjustment of the height of the second roller. It can avoid the situation where the heights on both sides of the second roller are different after adjustment, solving the problem that the existing clamping mechanism is inconvenient for synchronously adjusting the heights at both ends of the rotating shaft.

[0014] In the present utility model, the adjusting assembly can be adjusted according to the width of the strip steel, so that the limiting assembly can be stuck on both sides of the strip steel, facilitating the limitation of strip steels with different widths.

[0023] Please refer to Figure 1 With Figure 2 , the present invention provides a technical solution for a clamping mechanism for a slitting machine that is easy to adjust: A clamping mechanism for a slitting machine that is easy to adjust includes a slitting machine main body 1. On both sides of the top of the slitting machine main body 1, support seats 2 are provided. On the top of the support seats 2, mounting openings 3 are provided. Inside the mounting openings 3, threaded rods 4 are vertically provided. On the outer side of the threaded rods 4, threaded sleeves 5 are provided. On the opposite sides of the two threaded sleeves 5, support blocks 6 are provided. At the bottom of the opposite sides of the two support seats 2, a first roller 10 is jointly provided. In the middle of the two support blocks 6, a second roller 11 is jointly provided. At the top of the two support seats 2, a driving assembly 9 capable of synchronously rotating the two threaded rods 4 is jointly provided. On the top of one side of the slitting machine main body 1, a limiting assembly 7 for preventing the metal coil from undergoing lateral displacement during winding is provided. Inside one side of the slitting machine main body 1, an adjusting assembly 8 for changing the distance between the two limiting assemblies 7 according to the different widths of the metal coil is provided.

[0024] Please refer to Figure 3 , the limiting assembly 7 includes a support tube 71 fixedly connected to the top of the support plate 86. Inside the support tube 71, a slider 72 is slidably connected. At the top of the slider 72, a support rod 73 is fixedly connected. At the top of the support rod 73, a limiting frame 74 is fixedly connected. By respectively clamping the limiting frames 74 on both sides of the strip steel, as the strip steel moves, the limiting frames 74 on both sides can prevent the strip steel from undergoing lateral displacement and avoid the strip steel being affected during shearing.

[0025] Please refer to Figure 4 , the adjusting assembly 8 includes a bidirectional screw 81 rotatably connected to the top of the inner cavity of the slitting machine main body 1. On both sides of the bidirectional screw 81, support sleeves 83 are threadedly connected. Horizontally, a sliding hole 85 is opened at the top of the slitting machine main body 1. At the top of the support sleeve 83, a connecting rod 84 is fixedly connected. The top of the connecting rod 84 passes through the sliding hole 85 and is fixedly connected to a support plate 86. At the top of one side of the slitting machine main body 1, a driving motor 82 is fixedly connected. One end of the output shaft of the driving motor 82 passes through one side of the slitting machine main body 1 and is fixedly connected to the bidirectional screw 81. By controlling the driving motor 82 to drive the bidirectional screw 81 to rotate, the bidirectional screw 81 and the support sleeve 83 perform threaded transmission, driving the two limiting frames 74 to move in opposite directions, so that the limiting frames 74 are respectively clamped on both sides of the strip steel.

[0026] Please refer to Figure 5 As shown in Figure 5 , the driving assembly 9 includes a driving frame 91 fixedly connected to the tops of two support seats 2. The middle parts of the left and right inner walls of the driving frame 91 are respectively rotatably connected with worm gears 92. A driving rod 93 is commonly connected to the opposite sides of the two worm gears 92. The top end of the threaded rod 4 passes through the driving frame 91 and is fixedly connected with a worm wheel 96. The rear sides of the worm wheels 96 are respectively meshed and connected with the worm gears 92. The middle part of the driving rod 93 is fixedly connected with a first bevel gear 94. The middle part of the top end of the driving frame 91 is rotatably connected with a winch 97. The bottom end of the winch 97 is fixedly connected with a second bevel gear 95. One side of the second bevel gear 95 is meshed and connected with the first bevel gear 94. Rotating the winch 97 drives the meshing transmission between the second bevel gear 95 and the first bevel gear 94. The worm gears 92 on both sides are driven to rotate in the same direction through the driving rod 93, so that the worm gears 92 are respectively meshed and transmitted with the worm wheels 96 on both sides, driving the threaded rods 4 on both sides to rotate synchronously, preventing the heights of the two ends of the second roller 11 from being different after adjustment.

[0027] The working principle and usage process of the present utility model are as follows: Install the strip steel on the outside of the first roller 10. According to the height of the strip steel, rotate the winch 97 to drive the meshing transmission between the second bevel gear 95 and the first bevel gear 94. The worm gears 92 on both sides are driven to rotate in the same direction through the driving rod 93, so that the worm gears 92 are respectively meshed and transmitted with the worm wheels 96 on both sides, driving the threaded rods 4 on both sides to rotate synchronously. According to the screw thread transmission between the threaded rod 4 and the thread sleeve 5, the second roller 11 can be driven to move up and down, so that the second roller 11 presses on the top of the strip steel, clamping the strip steel. Then, according to the width of the strip steel, control the driving motor 82 to drive the bidirectional screw rod 81 to rotate, so that the bidirectional screw rod 81 is in screw thread transmission with the support sleeve 83, driving the two limiting frames 74 to move in opposite directions, so that the limiting frames 74 are respectively stuck on both sides of the strip steel. As the strip steel moves, the limiting frames 74 on both sides can prevent the strip steel from undergoing lateral displacement, avoiding the influence on the strip steel during shearing.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
