[0002] CN215516033U discloses a fixing device for a deviation-correcting mechanical structure, comprising a frame, a support beam, a pressure roller, a pressure roller lifting hydraulic cylinder, and a variable-frequency first motor. A pressure roller lifting hydraulic cylinder is provided at the entrance of the frame to fix the pressure roller to a pressure roller swing frame, the pressure roller swing frame is connected to the support beam via a pin, and one axial end of the pressure roller is connected to the variable-frequency first motor via a coupling. In the existing fixing device for the deviation-correcting structure, a roller pressing member is provided to press the surface of the wound steel coil during the winding process of the steel strip, which is conducive to better fitting the steel strip during winding. However, during the winding process, the pressing position of the roller pressing member is single and the pressing range is limited. When the steel strip is winding and the tail of the steel strip is swung, the force acting on the single roller pressing member is large, which is not conducive to stable winding of the tail end of the steel strip. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fixing device for a deviation-correcting mechanical structure.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a fixing device for a correction mechanical structure, including a mounting seat, the vertical section surface of the mounting seat is slidably connected to a movable frame, the top of the bending section of the movable frame is rotatably connected to a winding roller, the top of the movable frame is rotatably connected to a flip frame, the end of the flip frame is connected to a pressing bracket through an elastic support member, the bottom end of the pressing bracket is connected to a first pressing roller, an arc-shaped electric telescopic rod is fixedly connected to the surface of the pressing bracket, and the telescopic end of the arc-shaped electric telescopic rod is connected to a second pressing roller.

[0005] It should be understood that in the process of the winding roller winding the steel strip, by adjusting the flip angle of the flip frame, the first pressing roller is driven to press the surface of the steel coil, so that the steel strip is close to the steel coil during the winding process, which is beneficial to reducing the volume of the entire steel coil. After the pressing adjustment is completed by the first pressing roller, the second pressing roller is pushed by the arc-shaped electric telescopic rod to press the steel coil close to the initial position of the steel strip winding. On the one hand, the pressing points on the steel coil are increased, which is beneficial to increase the pressing range and enhance the stability of the winding. On the other hand, when the steel coil is wound to the tail end, the second pressing roller is close to the initial position of the steel strip winding, which is beneficial to press the winding tail end of the steel strip close to reduce the swing amplitude of the tail end.

[0006] As an optional technical solution, two slide rails are fixedly provided on the mounting seat, and four sliding blocks slidably connected to the slide rails are fixedly connected to the movable frame at positions corresponding to the two slide rails.

[0007] It should be understood that the sliding connection between the slider and the slide rail plays a role in slidingly mounting the movable frame on the longitudinal section of the mounting seat;

[0008] As an optional technical solution, the flip frame further includes an electric cylinder, which is fixedly mounted on the surface of the movable frame. A connecting rod is rotatably connected between the end of the telescopic rod of the electric cylinder and the end of the flip frame away from the first pressing roller.

[0009] As an optional technical solution, the elastic support member includes two first support rods, a groove block is fixedly connected between the two first support rods, the groove block is fixedly connected to the end of the pressing bracket away from the first pressing roller, the two first support rods are slidably inserted into the end of the flip frame, and a second support spring is sleeved on the surface of the two first support rods, and the two ends of the second support spring are respectively fixedly connected to the end of the flip frame and the inner wall of the groove block.

[0010] As an optional technical solution, the arc-shaped electric telescopic rod includes an arc-shaped track, which is fixedly mounted on the surface of the pressing bracket. An arc-shaped plate is slidably inserted inside the arc-shaped track, and an arc-shaped rod is slidably inserted inside the arc-shaped plate. A first support spring is sleeved on the surface of the arc-shaped rod, and the two ends of the first support spring are respectively fixedly connected to the ends of the arc-shaped plate and the arc-shaped rod. The end face of the arc-shaped rod is connected to the second pressing roller. A driving assembly is also included for driving the arc-shaped plate to move in the arc-shaped track.

[0011] As an optional technical solution, the driving assembly includes a mounting bracket and an arc-shaped rack. The mounting bracket is fixedly mounted on the surface of the pressing bracket, and the arc-shaped rack is fixedly connected to the arc-shaped surface of the arc-shaped plate. A first motor is fixedly mounted on the end of the mounting bracket, and a driving gear is fixedly connected to the output end of the first motor, which is engaged with the arc-shaped rack.

[0012] As a further optimized technical solution, a gas spring is fixedly installed on the inner bottom surface of the groove block, and a pressure sensor is fixedly connected to the end of the flip frame. The end of the gas spring contacts and squeezes the pressure sensor.

[0013] It should be understood that by setting up a pressure sensor and a gas spring, during the pressing process, the entire pressing bracket will produce relative movement with the end of the flip frame, and the pressing bracket will synchronously drive the gas spring inside the groove block to squeeze the pressure sensor. The tighter the pressure is pressed, the greater the pressure detected by the pressure sensor.

[0014] If further explanation is needed, in the process of the winding roller winding the steel strip, the steel coil will gradually become thicker, which will react to the first pressing roller and the second pressing roller, and then indirectly act on the pressing bracket. The pressing bracket will act on the pressure sensor through the groove block and the gas spring. When the pressure sensor reaches a value close to the limit, the flip frame is adjusted to flip and the first pressing roller and the second pressing roller are raised to a specified height to avoid jamming. The whole process realizes the automatic recognition of the change in the thickness of the steel coil, which is conducive to timely and active adjustment of the flip frame to control the first pressing roller and the second pressing roller to maintain a reasonable pressure degree, which is conducive to avoiding jamming.

[0015] As an optional technical solution, the first pressing roller includes a first pressing ring, the first pressing ring is fixedly connected to the end of the pressing bracket, and the first roller is rotatably connected inside the first pressing ring.

[0016] As an optional technical solution, the second pressing roller includes a second pressing ring, the second pressing ring is fixedly connected to the end surface of the arc rod, and the second roller is connected inside the second pressing ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By setting the first pressing roller and the second pressing roller, on the one hand, the points of pressing on the steel coil are increased, which is beneficial to increasing the range of pressing and enhancing the stability of winding. On the other hand, when the steel coil is wound to the tail end, the second pressing roller is close to the initial position of the steel strip winding, which is beneficial to pressing the winding tail end of the steel strip and reducing the swing amplitude of the tail end.

[0019] During the process of the winding roller winding the steel strip, the steel coil will gradually become thicker, which will react to the first pressing roller and the second pressing roller, and then indirectly act on the pressing bracket. The pressing bracket will act on the pressure sensor through the groove block and the gas spring. When the pressure sensor reaches a value close to the limit, the turning frame is adjusted to turn over, and the first pressing roller and the second pressing roller are raised to a specified height to avoid jamming. The whole process realizes the automatic recognition of the change in the thickness of the steel coil, which is conducive to timely and active adjustment of the turning frame to control the first pressing roller and the second pressing roller to maintain a reasonable pressure degree, which is conducive to avoiding jamming.

[0028] The specific mounting seat 1 has a transverse section 101 and a longitudinal section 102;

[0029] During the process of winding the steel strip by the winding roller 3, by adjusting the flip angle of the flip frame 4, the first pressing roller is driven to press the surface of the steel coil, so that the steel strip is close to the steel coil during the winding process, which is beneficial to reducing the volume of the entire steel coil. After the pressing adjustment is completed by the first pressing roller, the second pressing roller is pushed by the arc-shaped electric telescopic rod 7 to press the steel coil close to the initial position of the steel strip winding. On the one hand, the pressing points on the steel coil are increased, which is beneficial to increase the pressing range and enhance the stability of the winding. On the other hand, when the steel coil is wound to the tail end, the second pressing roller is close to the initial position of the steel strip winding, which is beneficial to press the winding tail end of the steel strip close to reduce the swing amplitude of the tail end.

[0030] As an optional embodiment, two slide rails 9 are fixedly provided on the mounting base 1 , and four sliders 10 slidably connected to the slide rails 9 are fixedly connected to the movable frame 2 at positions corresponding to the two slide rails 9 .

[0031] It should be understood that the sliding connection between the slider 10 and the slide rail 9 plays a role in slidingly mounting the mobile frame 2 on the longitudinal section 102 of the mounting base 1;

[0032] Specifically, a threaded drive assembly is provided at the bottom end of the movable frame 2, and the threaded drive assembly includes a second motor 28. The second motor 28 is fixedly mounted on the top surface of the transverse section 101 of the mounting seat 1, and the output end is fixedly connected to a threaded rod 29. A threaded sleeve 30 is threadedly connected to the surface of the threaded rod 29. The threaded sleeve 30 is fixedly mounted on the side wall of the movable frame 2 near the bottom end. When it is necessary to move and fine-tune the winding roller 3 to align the winding direction of the steel strip, the second motor 28 is started, and the second motor 28 drives the threaded rod 29 to rotate. The threaded rod 29 will threadably drive the threaded sleeve 30 to move, and the threaded sleeve 30 synchronously drives the movable frame 2 to move to achieve deviation correction adjustment.

[0034] It should be understood that when the turning frame needs to be adjusted in turning angle, the electric cylinder 11 is started, the telescopic end of the electric cylinder 11 acts on the connecting rod 12, and the connecting rod 12 links the turning frame 4 to turn, thereby realizing the turning adjustment of the turning frame 4.

[0038] It should be understood that after the first pressing roller completes the pressing, the driving assembly drives the arc plate 17 to move in the arc track 16. The arc plate 17 drives the second pressing roller to further press the surface of the steel coil under the elastic support of the arc rod 18 and the first support spring 19. Cooperating with the first pressing roller, it not only increases the pressing points and expands the pressing range, but also increases the pressure on the initial position close to the steel coil winding, which is beneficial to further improve the stability of the steel coil winding process.

[0043] It should be understood that by setting up the pressure sensor 25 and the gas spring 24, during the pressing process, the entire pressing bracket 5 will produce relative movement with the end of the flip frame 4, and the pressing bracket 5 will synchronously drive the gas spring 24 inside the groove block 14 to squeeze the pressure sensor 25. The tighter the pressing, the greater the pressure detected by the pressure sensor 25.

[0044] If further explanation is needed, in the process of the winding roller 3 winding the steel strip, the steel coil will gradually become thicker, which will react to the first pressing roller and the second pressing roller, and then indirectly act on the pressing bracket 5. The pressing bracket 5 will act on the pressure sensor 25 through the groove block 14 and the gas spring 24. When the pressure sensor 25 reaches a value close to the limit, the turning frame 4 is adjusted to turn over, and the first pressing roller and the second pressing roller are raised to a specified height to avoid jamming.
