Description

Technical Field

[0001] This utility model relates to the field of uncoiler technology, specifically to an auxiliary support device for an uncoiler. Background Technology

[0002] In existing technologies, metal sheets are generally sheared using a metal sheet shearing production line. During shearing, the coiled metal sheet material is placed in an uncoiler. During operation, the uncoiler continuously unwinds and releases the metal sheet material. It should be noted that, in order to facilitate the rapid feeding of the metal sheet material into the uncoiler, the uncoiler generally adopts a cantilever structure design, that is, one end of the uncoiler's main shaft is fixed, and the other end is suspended, which is a cantilever uncoiler.

[0003] During the uncoiling and unwinding process using a cantilever uncoiler, the uncoiler spindle is suspended in the air. Under the weight of the heavy metal sheet coil, the uncoiler spindle is prone to deformation without appropriate auxiliary support. Once deformed, the uncoiler spindle cannot be used. Therefore, for cantilever uncoilers, it is particularly important to use an auxiliary support structure to support the uncoiler spindle.

[0004] Therefore, we propose an auxiliary support device for an uncoiler. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary support device for an uncoiler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support device for an uncoiler, comprising a base plate, an uncoiler body disposed on the top of the base plate, a threaded rod rotatably connected to the top of the base plate on one side of the uncoiler body, slide rails fixedly mounted on both sides of the threaded rod on the top of the base plate, a movable plate slidably connected to the top of the slide rails, a connecting pipe fixedly mounted in the middle of the bottom of the movable plate, the threaded rod being threadedly connected to the middle of the connecting block, a handwheel fixedly mounted at one end of the threaded rod, a hydraulic push rod fixedly mounted in the middle of the top of the movable plate, swing rods rotatably connected to the top of the movable plate on both sides of the hydraulic push rod, a lifting plate fixedly mounted on the top of the hydraulic push rod, a support roller rotatably connected to the top of the swing rod, a connecting rod fixedly mounted in the middle of the swing rod, a push rod rotatably connected in the middle of the connecting rod, and the other end of the push rod rotatably connected to the side of the lifting plate.

[0007] Optionally, the threaded rod is located directly below the unwinding spindle of the uncoiler body, and the length of the threaded rod is the same as the length of the unwinding spindle of the uncoiler body.

[0008] Optionally, the two slide rails are symmetrically arranged on the front and rear sides of the threaded rod, and a sliding block is slidably connected to the top of the slide rails. The bottom of the moving plate is fixedly installed with the top of the sliding block.

[0009] Optionally, the two swing rods are symmetrically arranged on both sides of the hydraulic push rod, and the top of the bottom moving plate of the two sets of swing rods is rotatably connected.

[0010] Optionally, the two ends of the connecting rod are respectively fixedly installed to the middle of two swing rods in the same group, and the push rod is located between the two swing rods.

[0011] Optionally, the diameter of the support roller is greater than the width of the swing rod, and the length of the support roller is less than the width of the moving plate.

[0012] Optionally, the overall length of the extended hydraulic push rod is less than the length of the swing rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This uncoiler uses an auxiliary support device. By setting support rollers, the hydraulic push rod first moves the lifting plate downward, and pushes the pull rod to open the two swing rods and the support rollers. After the metal sheet coil is placed on the uncoiler spindle, the hydraulic push rod moves the lifting plate upward, causing the push rod to pull the swing rod, so that the support rollers are in close contact with the bottom of the metal sheet coil and provide a certain support force. As the diameter of the metal sheet coil becomes smaller, the hydraulic push rod moves the lifting plate upward continuously, always providing support force for the metal sheet coil. When the diameter of the metal sheet coil decreases to the point of separating from the support rollers, the weight of the entire metal sheet coil will not affect the uncoiler spindle.

[0015] 2. The uncoiler uses an auxiliary support device, which is equipped with a threaded rod and a slide rail. The threaded rod is rotated by a handwheel, which in turn causes the connecting block to move the moving plate along the slide rail, so that the support roller can be adjusted to a suitable position according to the width of the metal sheet coil for support.

[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 protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides an auxiliary support device for an uncoiler, including a base plate 1, an uncoiler body 2 on the top of the base plate 1, a threaded rod 3 rotatably connected to the top of the base plate 1 on one side of the uncoiler body 2, slide rails 4 fixedly installed on both sides of the threaded rod 3 on the top of the base plate 1, a movable plate 7 slidably connected to the top of the slide rails 4, a connecting pipe fixedly installed in the middle of the bottom of the movable plate 7, the threaded rod 3 threadedly connected to the middle of the connecting block 8, a handwheel 5 fixedly installed at one end of the threaded rod 3, a hydraulic push rod 9 fixedly installed in the middle of the top of the movable plate 7, swing rods 10 rotatably connected to the top of the movable plate 7 on both sides of the hydraulic push rod 9, a lifting plate 11 fixedly installed on the top of the hydraulic push rod 9, a support roller 13 rotatably connected to the top of the swing rod 10, and a connecting rod 12 fixedly installed in the middle of the swing rod 10. A push rod 14 is rotatably connected to the middle of the connecting rod 12. The other end of the push rod 14 is rotatably connected to the side of the lifting plate 11. By setting the support roller 13, the hydraulic push rod 9 first drives the lifting plate 11 to move down. The push rod 14 opens the two swing rods 10 and the support roller 13. After the metal sheet coil is placed on the uncoiling spindle, the hydraulic push rod 9 drives the lifting plate 11 to move up, so that the push rod 14 pulls the swing rods 10, so that the support roller 13 is close to the bottom of the metal sheet coil and provides a certain support force. As the diameter of the metal sheet coil becomes smaller and smaller, the hydraulic push rod 9 drives the lifting plate 11 to move up continuously, always providing support force for the metal sheet coil. When the diameter of the metal sheet coil decreases to the point of separating from the support roller 13, the weight of the entire metal sheet coil will not affect the uncoiling spindle.

[0023] The threaded rod 3 is located directly below the uncoiling spindle of the uncoiler body 2, and the length of the threaded rod 3 is the same as the length of the uncoiling spindle of the uncoiler body 2.

[0024] Two slide rails 4 are symmetrically arranged on the front and rear sides of the threaded rod 3. A sliding block 6 is slidably connected to the top of the slide rail 4. The bottom of the moving plate 7 is fixedly installed with the top of the sliding block 6. By setting the threaded rod 3 and the slide rail 4, the threaded rod 3 is rotated by the handwheel 5, which in turn causes the connecting block 8 to move the moving plate 7 along the slide rail 4, so that the support roller 13 can be adjusted to a suitable position for support according to the width of the metal sheet coil.

[0025] Two swing rods 10 are symmetrically arranged on both sides of the hydraulic push rod 9, and the bottom moving plate 7 of the two sets of swing rods 10 are rotatably connected.

[0026] The two ends of the connecting rod 12 are fixedly installed to the middle of the two swing rods 10 in the same group, and the push rod 14 is located between the two swing rods 10.

[0027] The diameter of the support roller 13 is greater than the width of the swing rod 10, and the length of the support roller 13 is less than the width of the moving plate 7.

[0028] The overall length of the hydraulic push rod 9 after extension is less than the length of the swing rod 10.

[0029] Working principle:

[0030] The handwheel 5 drives the threaded rod 3 to rotate, which in turn causes the connecting block 8 to move the moving plate 7 along the slide rail 4. This allows the support roller 13 to be adjusted to a suitable position according to the width of the metal sheet roll for support. The hydraulic push rod 9 drives the lifting plate 11 to move down, and pushes the pull rod 14 to open the two swing rods 10 and the support roller 13. After the metal sheet roll is placed on the uncoiling spindle, the hydraulic push rod 9 drives the lifting plate 11 to move up, which causes the push rod 14 to pull the swing rods 10, so that the support roller 13 is pressed tightly against the bottom of the metal sheet roll and provides a certain support force. As the diameter of the metal sheet roll becomes smaller, the hydraulic push rod 9 drives the lifting plate 11 to move up continuously, always providing support force for the metal sheet roll. When the diameter of the metal sheet roll decreases to the point where it separates from the support roller 13, the weight of the entire metal sheet roll will not affect the uncoiling spindle.
