Description

Technical Field

[0001] The utility model relates to the technical field of reel assisting technology, in particular to an automatic rubber sleeve device. Background Art

[0002] In the field of metallurgical manufacturing, a coiler is generally used to wind the finished strip, that is, the finished strip is wound on the outer wall of the coiler's drum. Before winding the finished strip, a rubber sleeve is often put on the fan-shaped plate on the outer wall of the coiler's drum to prevent the outer wall of the drum from scratching the strip surface. The drum is composed of four fan-shaped plates. The coiler is provided with a pull rod that can slide along the axial direction. When the pull rod slides, the fan plates can be driven away from or close to each other, thereby changing the size of the coil core of the coiler. After the winding is completed, the finished strip can be removed from the coiler by changing the size of the coil core through the pull rod.

[0003] According to customer needs, coilers are often used to coil steel coils with different inner diameters, and at this time the rubber sleeve needs to be replaced. Currently, the rubber sleeve is installed by machining keyways and drilling threaded holes on the fan-shaped plate, or machining threaded holes on the end face of the fan-shaped plate, and then directly clamping the baffle into the keyway and tightening it with screws, or directly pressing the baffle onto the end face of the fan-shaped plate and then tightening it with bolts. However, machining the slots on the fan-shaped plate has a certain impact on the strength of the fan-shaped plate, and it is inconvenient to disassemble and replace the rubber sleeve at the equipment production site, which consumes manpower and material resources and affects equipment maintenance time. Utility Model Content

[0004] In order to quickly disassemble and assemble the rubber sleeve on the fan-shaped plate, the present application provides an automatic rubber sleeve device.

[0005] The present application provides an automatic rubber sleeve device, which adopts the following technical solution:

[0007] Optionally, the drive assembly includes a spring, both ends of which are fixedly connected to the telescopic blocking column and the fan-shaped plate respectively; when the spring is in a natural state, the telescopic blocking column extends out of the fan-shaped plate and abuts against the end face of the rubber sleeve.

[0008] Optionally, a pressure plate is fixedly connected to the fan-shaped plate, and a through hole is opened on the pressure plate for the telescopic blocking column to pass through; an abutment plate is provided on the telescopic blocking column; when the abutment plate abuts against the pressure plate, the telescopic blocking column extends out of the fan-shaped plate and the spring is in a compressed state.

[0009] Optionally, the telescopic blocking column is a polygonal column, the through hole is a matching polygonal hole, and the multi-deformable hole is used to prevent the telescopic blocking column from rotating on its own during operation.

[0010] Optionally, the telescopic stop column passes through the fan plate along the radial direction of the fan plate, and the driving assembly also includes a hook head, which is rotatably connected to the inner wall of the fan plate, and the rotation axis of the hook head is perpendicular to the axis of the fan plate. One end of the hook head is located on the moving path of the pull rod, and the other end of the hook head is hooked to the telescopic stop column; the pull rod slides to drive the hook head to rotate, and the hook head rotates to drive the telescopic stop column to slide.

[0011] Optionally, the sector plate is rotatably connected to a rotating shaft via a self-lubricating bearing, and the hook head is rotatably connected to the rotating shaft.

[0012] Optionally, the fan-shaped plate is provided with a mounting hole for the rotating shaft to pass through, and one end of the rotating shaft is provided with a cotter pin for preventing the rotating shaft from detaching after passing through the mounting hole.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The embodiment of the present application discloses a novel automatic rubber sleeve 13 blocking device, which is used to fix the rubber sleeve 13 when the winder 1 is winding normally; when the rubber sleeve 13 needs to be replaced, the device releases the limit on the rubber sleeve 13; the device includes four telescopic blocking columns 21, and the four telescopic blocking columns 21 are respectively arranged on four fan-shaped plates 12, and the telescopic blocking columns 21 are slidably connected to the fan-shaped plates 12 along the radial direction of the fan-shaped plates 12, and the fan-shaped plates 12 are provided with empty grooves for sliding of the telescopic blocking columns 21 along their own radial direction; a driving component for driving the telescopic blocking columns 21 to slide is provided in the empty grooves and the fan-shaped plates 12.

[0023] In the embodiment of the present application, the driving assembly includes a spring 22 and a hook 23; an abutment plate 25 is provided on the telescopic blocking column 21, and a step surface is provided in the empty groove; the two ends of the spring 22 are fixedly connected to the abutment plate 25 and the step surface, respectively, and the abutment plate 25 is closer to the outer surface of the fan-shaped plate 12; when the spring 22 is in a natural state, the telescopic blocking column 21 extends out of the fan-shaped plate 12 and abuts against the end face of the rubber sleeve 13, thereby limiting the rubber sleeve 13.

[0024] At the same time, in order to prevent the telescopic blocking column 21 from moving, a pressure plate 24 is also provided on the fan-shaped plate 12. The pressure plate 24 is fixedly connected to the empty slot by bolts, and a through hole is provided on the pressure plate 24 for the telescopic blocking column 21 to pass through; when the abutment plate 25 abuts the pressure plate 24, the spring 22 is in a compressed state, thereby providing a certain compression force to prevent the telescopic blocking column 21 from moving.

[0025] In this embodiment, the fan-shaped plate 12 is provided with a mounting hole along its width direction, and a rotating shaft 26 and a self-lubricating bearing are passed through the mounting hole. One end of the rotating shaft 26 passes through the mounting hole and is connected to a cotter pin 27, a hook head 23 and a retaining ring 28, so that the rotating shaft 26 is rotatably connected to the fan-shaped plate 12. The retaining ring 28 and the cotter pin 27 are installed on the rotating shaft 26 to prevent the rotating shaft 26 from detaching from the mounting hole during operation. Then the hook head 23 is rotatably connected to the rotating shaft 26 through the self-lubricating bearing; and one side of the hook head 23 is located on the moving path of the pull rod 11, and the other end is hooked to the lower end of the telescopic stop column 21.

[0026] When the pull rod 11 hits the end face of the hook head 23 and continues to move to the left, the hook head 23 rotates along the rotating shaft 26, and the hook head 23 hooks the telescopic stop column 21, forcing the telescopic stop column 21 to drop to 2-3 mm below the surface of the sector plate 12, which makes it easier to remove the rubber sleeve 13 from the reel.

[0027] When the reel is retracted to the unloading state, there is still a certain gap between the pull rod 11 and the end face of the hook head 23. Under the action of the spring 22, the telescopic blocking column 21 is higher than the outer circle of the fan-shaped plate 12. During the unloading process of the steel coil, the telescopic blocking column 21 blocks the rubber sleeve 13, so the rubber sleeve 13 will not move with the steel coil.

[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
