DETAILED DESCRIPTION

[0031] 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 of 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. Specific embodiment 1

[0033] See also Figures 1 to 3 The utility model is a width adjustment device for steel coil stripping, comprising a base 1 and mounting frames 103 arranged at both ends of the upper surface of the base 1, and an adjustment component 2 is arranged on one side of the upper surface of the base 1; the adjustment component 2 comprises an outer fixing plate 201 and a motor 203 installed at the bottom of the outer wall thereof, and an active gear disc 2031 is installed on the output shaft of the motor 203.

[0034] Specifically, an outer support roller 101 and an inner support roller 102 are sequentially installed on the other side of the upper surface of the base 1, and the outer support roller 101 and the inner support roller 102 are located on both sides of the adjusting roller 301. Support plates 104 are fixedly connected to the front and rear ends of one side edge of the base 1. Pressing rollers 1041 are installed above and below the front and rear adjacent support plates 104. A driven gear plate 2041 is arranged above the active gear plate 2031. A threaded rod 204 is installed at the center of the rear end face of the driven gear plate 2041. The other end of the threaded rod 204 passes through the outer wall of the outer fixed plate 201 in sequence. The bearing, the threaded holes on the front end face of the outer movable seat 205 and the threaded holes on the front end face of the inner movable seat 206 are connected to the bearing on the inner wall of the inner fixed plate 202. Guide rods 2011 are fixedly connected to both sides of the inner wall of the outer fixed plate 201. The other end of the guide rod 2011 passes through the through holes on both sides of the front end faces of the outer movable seat 205 and the inner movable seat 206 in sequence and is connected to the inner wall of the inner fixed plate 202. The bottoms of the outer fixed plate 201 and the inner fixed plate 202 are fixed on the upper surface of the base 1, and mounting frames 103 are installed on both sides of the upper surfaces of the outer movable seat 205 and the inner movable seat 206.

[0035] Furthermore, the outer support roller 101 and the inner support roller 102 can support the steel coil, and the upper and lower groups of pressure rollers 1041 can flatten the steel coil. This is the prior art, so it will not be described in detail here. The operation of the motor 203 can drive the active gear plate 2031 to rotate, and the gears on the outer wall of the driven gear plate 2041 on the outer wall of the active gear plate 2031 are meshed and connected to play a transmission role. The threaded rod 204 rotates under the action of the driven gear plate 2041, wherein the outer walls of the threaded rod 204 are respectively provided with positive threads and negative threads, and the positive threads and negative threads are respectively meshed and connected with the internal threads in the walls of the threaded holes on the end faces of the outer moving seat 205 and the inner moving seat 206, playing a transmission role, so that the outer moving seat 205 and the inner moving seat 206 move in opposite directions or opposite directions.

[0036] The operation process of this embodiment is as follows: the outer support roller 101 and the inner support roller 102 support and assist in conveying the steel coil, then the motor 203 is started, the output shaft of the motor 203 rotates to drive the active toothed disc 2031 to rotate, and the gear on the outer wall of the active toothed disc 2031 is meshed with the gear on the outer wall of the driven toothed disc 2041. Therefore, when the active toothed disc 2031 rotates, the driven toothed disc 2041 is driven to rotate, and when the driven toothed disc 2041 rotates, the inner threaded rod 204 is driven to rotate, wherein the outer wall of the threaded rod 204 The front and rear ends are respectively provided with positive threads and negative threads, and the positive threads and negative threads are respectively engaged with the internal threads in the walls of the threaded holes on the end faces of the outer movable seat 205 and the inner movable seat 206. Therefore, when the threaded rod 204 rotates and with the assistance of the guide rod 2011, the outer movable seat 205 and the inner movable seat 206 can move in opposite directions, and then the distance between the front and rear mounting frames 103 and their internal limiting rollers 1031 can be adjusted simultaneously and quickly, which saves time and effort, has high work efficiency, and has a relatively simple structure. Specific embodiment 2

[0038] See also Figure 2 , 4 5. Based on the specific embodiment 1, what is different from the first embodiment is that: a clamping component 3 and a protective frame 4 are provided, the clamping component 3 includes an adjusting roller 301 and a rotating shaft 3011 installed at the center position inside the adjusting roller 301, and both ends of the rotating shaft 301 respectively penetrate the front and rear end surfaces of the adjusting roller 301 and are connected to the bearings inside the adjacent bearing seat 302, thereby solving the problem that the existing stainless steel coil strip width adjustment device supports the steel coil by the first support roller and the second support roller when in use, and this method will cause the steel coil to be relatively loose during the transportation process, affecting the subsequent steel coil flattening and striping operations. At the same time, there is a lack of protective measures during the transportation of the steel coil, and its outer edge may scratch the surrounding staff, posing a safety hazard.

[0039] Specifically, limiting rollers 1031 are installed on both sides of the interior of the installation frame 103, a protective pad 401 is provided on the inner wall of the protective frame 4, an electric push rod 303 is installed at the bottom center of the bearing seat 302, and the bottom end of the electric push rod 303 is installed on the upper surface of the base 1.

[0040] Furthermore, the adjusting roller 301 rotates under the action of the rotating shaft 3011, and the height position of the adjusting roller 301 can be adjusted by the electric push rod 303, and the surface of the steel coil can be squeezed to make the steel coil compacted. The protective pad 401 can wrap the outer edge of the steel coil inside to play a protective role.

[0041] The operation process of this embodiment is as follows: when the steel coil is supported by the outer support roller 101 and the inner support roller 102, the electric push rod 303 is started, and the telescopic end of the electric push rod 303 contracts to drive the bearing seat 302 to move downward, and the downward movement of the bearing seat 302 will drive the rotating shaft 3011 and the adjusting roller 301 on its outer wall to move downward, and make the adjusting roller 301 press down on the surface of the steel coil, so as to press the steel coil tightly to prevent the steel coil from being too loose during the transportation process, affecting the subsequent steel coil flattening and striping operations. At the same time, during the transportation of the steel coil, the steel coil will be inserted into the front and rear adjacent protective frames 4, and the two sides of the steel coil will be stuck on the outer wall of the protective pad 401, so that the outer edge of the steel coil is wrapped in the inner side of the protective pad 401, which can protect the surrounding staff and prevent the outer edge of the steel coil from scratching the surrounding staff during the transportation process, thereby improving safety performance.
