DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-5As shown, the utility model provides a strip steel unwinding device that is easy to adjust, including an unwinding device body 1, which is suitable for unwinding strip steel, the unwinding device body 1 includes an unwinding bracket 2, a hydraulic cylinder 3 is fixedly installed on the top of the rear side of the unwinding bracket 2, an adjustment unit is arranged at the front end of the unwinding bracket 2, and a resistance unit is arranged in front of the adjustment unit. The adjustment unit includes a hydraulic rod 31 arranged on the output end of the hydraulic cylinder 3, a fixing ring 1 32 is fixedly sleeved on the outer surface of the rear end of the hydraulic rod 31, a fixing ring 2 33 is fixedly sleeved on the outer surface of the front end of the hydraulic rod 31, and the outer surfaces of the surroundings of the fixing ring 2 33 are fixed A support vertical plate 34 is installed, and a movable groove 35 is opened inside the support vertical plate 34. A rotating shaft 1 36 is fixedly installed on the outer surfaces of the four sides of the fixed ring 1 32. A pushing rod 37 is rotatably installed at the inner axis of the rotating shaft 1 36. A rotating shaft 2 38 is rotatably installed on the other end of the pushing rod 37. The rotating shaft 2 38 is slidably connected to the rear outer surface of the support vertical plate 34. A connecting rod 39 is fixedly installed on the other end of the rotating shaft 2 38. The other end of the connecting rod 39 passes through the movable groove 35 and extends on the front outer surface of the support vertical plate 34. A fitting ring plate 310 is fixedly installed on the other end of the connecting rod 39.

[0027] Furthermore, during the uncoiling process, as the outer ring diameter of the strip steel coil becomes smaller, the hydraulic rod 31 can be driven to extend and retract through the output end of the hydraulic cylinder 3. At this time, the push rod 37 changes its own inclination angle under the extension and retraction of the hydraulic rod 31, and its two ends rotate at the internal axis of the rotating shaft 1 36 and the rotating shaft 2 38. The movement of the rotating shaft 2 38 around causes the surrounding fitting ring plates 310 to move relative to each other, tightly fitting on the outer surface of the strip steel coil, thereby preventing the outer ring of the strip steel coil from loosening.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, a cavity 311 is opened on the inner surface of the fitting ring plate 310, and fixed cross bars 312 are fixedly installed on both sides of the interior of the cavity 311, and a roller 313 is rotatably sleeved on the outer surface of the fixed cross bar 312.

[0030] Furthermore, when the steel strip is pulled, the outer surface of the steel strip contacts the roller 313 on the inner surface of the fitting ring plate 310, and the pulling causes the roller 313 to rotate on the outer surface of the fixed cross bar 312, thereby reducing the friction between the fitting ring plate 310 and the steel strip and promoting smoothness.

[0031] Example 3

[0032] like Figure 1-5As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the resistance unit includes a resistance plate 314 arranged on the outer surface around the front end of the hydraulic rod 31, a piston column 315 is fixedly installed on the inner surface of the resistance plate 314, a limiting plate 316 is fixedly installed on the other end of the piston column 315, a sleeve 317 is movably sleeved on the outer surface of the limiting plate 316, a return spring 318 is fixedly installed on the inner bottom end of the sleeve 317, and the other end of the return spring 318 is fixedly installed on the outer surface of the bottom end of the limiting plate 316.

[0033] Furthermore, by placing the strip coil roller and the crane at the front end of the uncoiling bracket 2, the roller core is correspondingly inserted into the front end outer surface of the hydraulic rod 31. At this time, the contact plate 314 contacts the inner wall of the roller core, and cooperates with the elastic driving force of the return spring 318 to prompt the piston column 315 to move outward, thereby prompting the piston column 315 to push the contact plate 314 to fit tightly against the inner wall of the roller core.

[0034] The working principle of the easily adjustable strip unwinding device is described in detail below.

[0035] like Figure 1-5 As shown, when in use, the strip steel coiling roller is placed at the front end of the uncoiling support 2 with the crane, so that the roller core is correspondingly inserted into the front end outer surface of the hydraulic rod 31. At this time, the abutment plate 314 abuts against the inner wall of the roller core, and the elastic driving force of the return spring 318 is cooperated to cause the piston column 315 to move outward, thereby causing the piston column 315 to push the abutment plate 314 to fit closely against the inner wall of the roller core. In the uncoiling process, as the outer ring diameter of the strip steel coiling roller becomes smaller, the hydraulic rod 31 can be extended and retracted through the output end of the hydraulic cylinder 3. At this time, the push rod 37 is in the hydraulic The pressure rod 31 changes its inclination angle under the extension and contraction, and its two ends rotate at the internal axis of the rotating shaft 1 36 and the rotating shaft 2 38. The movement of the rotating shaft 2 38 around causes the surrounding fitting ring plates 310 to move relatively, tightly fitting on the outer surface of the strip steel roll roller to prevent the outer ring of the strip steel roll from loosening. When the strip steel plate is pulled, the outer surface of the strip steel plate contacts the roller 313 on the inner surface of the fitting ring plate 310, and the pulling causes the roller 313 to rotate on the outer surface of the fixed cross bar 312, thereby reducing the friction between the fitting ring plate 310 and the strip steel plate and promoting smoothness.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
