Description

Technical Field

[0001] This application relates to the field of armored reels for steel strip coils, and more particularly to an armored reel adapted to steel strip coils with multiple inner diameters. Background Technology

[0002] Steel strip coils are widely used in industrial production, especially during transportation and storage, where armored reels are required for support and protection. Traditional armored reels typically employ a fixed structural design and are suitable for steel strip coils with specific inner diameters.

[0003] Since the inner diameter of the wound steel strip is fixed, and the structure of the armored reel is also fixed, when the inner diameter of the steel strip does not match the armored reel, it cannot be directly installed on the armored reel. The steel strip needs to be rewound or replaced with an armored reel of a different size before it can be installed on the armored reel or other winding equipment, which increases the difficulty of operation and reduces work efficiency. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide an armored reel that is adaptable to multi-inner-diameter steel strip coils.

[0005] An armored reel adaptable to multi-inner-diameter steel strip coils includes:

[0006] A fixed chassis has multiple guide grooves on its surface, arranged in a circular array around the central axis of the fixed chassis, and extending radially along the fixed chassis.

[0007] The adjustment assembly includes an inner diameter adjusting ring coaxial with the fixed chassis, multiple sliders, and guide threaded posts. Each slider engages with the guide groove. The guide threaded posts pass through the center of the fixed chassis and are perpendicular to the fixed chassis. The inner diameter adjusting ring is fitted onto the guide threaded posts. The outer circumferential surface of the inner diameter adjusting ring is tapered and can move along the extension direction of the guide threaded posts. The sliders abut against the outer circumferential surface of the inner diameter adjusting ring. When the inner diameter adjusting ring moves, the sliders slide along the guide grooves, and the inner wall surface of the steel strip coil abuts against the side of the slider opposite to the inner diameter adjusting ring.

[0008] By adopting the above scheme, since the slider is always in contact with the inner diameter adjusting ring, the edges of all sliders on the side away from the inner diameter adjusting ring are located on the same circumferential surface. When the inner diameter adjusting ring moves, the conical surface of the inner diameter adjusting ring pushes the slider to slide along the guide groove, and the inner diameter of the circumferential surface where the slider is located changes, so that multiple sliders can carry steel strip coils with different inner diameters.

[0009] In one embodiment, the adjusting assembly further includes a movable ring that abuts against the inner diameter adjusting ring, and the inner wall surface of the movable ring is threadedly connected to the guide thread post.

[0010] By adopting the above scheme, the moving ring will abut against the inner diameter adjusting ring as it moves along the threaded column, thereby pushing the inner diameter adjusting ring to move and limiting the inner diameter adjusting ring to prevent it from sliding arbitrarily along the guide threaded column.

[0011] In one embodiment, the inner wall surface of the inner diameter adjusting ring includes an abutment ring plate, the abutment ring plate is fitted with the guide threaded post and one side abuts against the moving ring, and the side of the moving ring opposite to the abutment ring plate is flush with the inner diameter adjusting ring.

[0012] By adopting the above solution, if the moving ring directly abuts against the inner diameter adjusting ring, the moving ring will occupy a large space on one side of the steel strip coil. The moving ring being located inside the inner diameter adjusting ring can save space.

[0013] In one embodiment, the outer peripheral surface of the guide thread post includes a sliding plane, and the inner wall surface of the abutment ring plate engages with the sliding plane.

[0014] By adopting the above solution, the threads on the surface of the threaded column are prevented from affecting the sliding of the inner diameter adjusting ring.

[0015] In one embodiment, the outer circumferential surface of the inner diameter adjusting ring is provided with a limiting groove, the bottom surface of the limiting groove is in the same direction as the generatrix of the outer circumferential surface of the inner diameter adjusting ring, and the slider is provided with a limiting strip that cooperates with the limiting groove.

[0016] By adopting the above solution, since the moving ring will have surface friction with the inner diameter adjusting ring during rotation, the inner diameter adjusting ring will rotate with the moving ring. The inner diameter adjusting ring will rub against the slider, causing the slider to deviate and fail to provide stable support for the steel strip coil. Through the cooperation of the limiting strip and the limiting groove, the slider will not deflect during movement.

[0017] In one embodiment, the slider includes a support portion and a sliding portion, the sliding portion cooperating with the guide groove and located at the bottom of the support portion, the limiting strip located on the support portion, and the contact surface between the support portion and the steel strip coil is curved.

[0018] By adopting the above solution, sharp edges are avoided on the contact surface between the slider and the steel strip coil, thus preventing scratches on the inner wall of the steel strip coil.

[0019] In one embodiment, the sliding part is provided with a guide hole, and the guide groove is provided with a guide rod that cooperates with the guide hole. The guide rod extends in the same direction as the guide groove.

[0020] By adopting the above solution, since the slider is prone to falling off, by setting a guide rod through the guide hole in the guide groove, it is possible to prevent the slider from falling off the guide groove, and at the same time, it is possible to prevent the slider from shifting during movement, which would lead to unstable support.

[0021] In one embodiment, the inner diameter adjusting ring has a baffle plate on the side opposite to the fixed base, the baffle plate is sleeved on the guide threaded post, and the baffle plate has a fastener on the side opposite to the inner diameter adjusting ring.

[0022] By adopting the above solution, since the steel strip coil is prone to slipping, the baffle plate plays a limiting role in preventing the steel strip coil from slipping off the armored reel.

[0023] In one embodiment, the fastener has a insert rod passing through the baffle on the side facing the inner diameter adjusting ring, and the movable ring has a hole that mates with the insert rod.

[0024] By adopting the above solution, after inserting the insertion rod into the insertion hole, the moving ring can be rotated by rotating the baffle. Because the baffle has a larger diameter, the rotation of the moving ring requires less effort.

[0025] In one embodiment, the insertion rod is detachably connected to the fastener, and the baffle surface is provided with a plurality of weight-reducing through holes in a circumferential array.

[0026] By adopting the above solution, when it is not necessary to use the baffle to drive the moving ring to rotate, the insert rod can be removed from the fastener, avoiding the gap between the baffle and the steel strip coil. The weight-reducing through hole can reduce the weight of the baffle and can also serve as a fulcrum for rotating the baffle.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. All the sliders are located on the same circumferential surface on the side away from the inner diameter adjusting ring. When the moving ring is rotated, the moving ring slides along the guide thread column. The moving ring drives the inner diameter adjusting ring to move. When the inner diameter adjusting ring moves, the conical surface of the inner diameter adjusting ring pushes the slider to slide along the guide groove. The inner diameter of the circumferential surface where the slider is located changes, so that multiple sliders can carry steel strip coils with different inner diameters.

[0029] 2. As the moving ring rotates, it will experience surface friction with the inner diameter adjusting ring. The inner diameter adjusting ring will rotate along with the moving ring. The friction between the inner diameter adjusting ring and the slider will cause the slider to deviate, making it unable to provide stable support for the steel strip coil. By using the limit strip and the limit groove, the slider will not deflect during movement. By using the guide rod and the guide hole, the slider can be prevented from falling out of the guide groove. At the same time, it can further prevent the slider from deviating during movement, which would lead to unstable support.

[0030] 3. The baffle plate limits the steel strip coil, preventing it from slipping off the armored disc. When the fastener is installed with the insert rod, the insert rod engages with the insertion hole in the moving ring, using the weight-reducing through hole as the force point for rotation, causing the baffle plate to rotate. The baffle plate then drives the moving ring to rotate via the insert rod. Because the baffle plate has a larger diameter, the rotation of the moving ring requires less effort.

[0038] Therefore, it is necessary to provide an armored reel that can be adapted to steel strip coils with different inner diameters.

[0039] Please see Figure 1-2 , Figure 1 An exploded view of an armored reel adapted to multi-diameter steel strip coils, provided in the first embodiment of this application, includes: a fixed base 1, an adjusting assembly 2, and a baffle 3.

[0040] Please refer to the following: Figure 3-4 , Figure 3This is a cross-sectional view of an armored reel adapted for multi-inner-diameter steel strip coils provided in this application. The fixed base 1 has multiple guide grooves 11 on its surface, with 3-5 grooves evenly distributed on the surface of the fixed base 1 in a circumferential array around the central axis of the fixed base 1, extending radially along the fixed base 1. Guide rods 12 are provided inside the guide grooves 11, extending in the same direction as the guide grooves 11. Through holes are provided on the side of the fixed base 1, through which the guide rods 12 are inserted into the guide grooves 11. The fixed base 1 is made of metal, possessing high strength and rigidity. The guide grooves 11 on its surface have a depth of 2-5 mm and a width of 10-15 mm, and can be rectangular or trapezoidal. Guide rods 12 are provided inside the guide grooves 11, with a diameter of 5-8 mm. The material can be stainless steel or high-strength alloy to improve wear resistance and corrosion resistance. The guide rods 12 are positioned along the direction of the guide grooves 11 to ensure the stability of the slider 22 during sliding.

[0041] Please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of the inner diameter adjusting ring 21. The adjusting assembly 2 includes the inner diameter adjusting ring 21, multiple sliders 22, guide threaded posts 23, and a moving ring 24. The outer circumferential surface of the inner diameter adjusting ring 21 is conical. The inner wall of the inner diameter adjusting ring 21 is provided with an abutment plate 211, which is sleeved on the guide threaded posts 23, serving as a guide and limiting element. The inner diameter adjusting ring 21 can be made of aluminum alloy or magnesium alloy, ensuring strength while reducing weight. The outer circumferential surface of the inner diameter adjusting ring 21 is provided with a limiting groove 212. The bottom surface of the limiting groove 212 extends in the same direction as the generatrix of the outer circumferential surface of the inner diameter adjusting ring 21, with a depth of 5-10 mm. In this application, the outer peripheral surface of the guide thread post 23 is polished to form two symmetrical sliding planes 231, and the inner diameter adjusting ring 21 cooperates with the sliding planes 231, thereby preventing the threads of the guide thread post 23 from obstructing the sliding of the inner diameter adjusting ring 21.

[0042] Please refer to the following: Figure 6 , Figure 6This is a schematic diagram of the slider 22. The slider 22 includes a supporting part 221 and a sliding part 222. The sliding part 222 cooperates with the guide groove 11 and is located at the bottom of the supporting part 221. The sliding part 222 has a guide hole 2221 that cooperates with the guide rod 12. The inner diameter of the guide hole 2221 is slightly larger than the diameter of the guide rod 12 to ensure that the slider 22 can slide smoothly. The material of the sliding part 222 can be engineering plastics such as polyoxymethylene or nylon. These materials have self-lubricating properties and can reduce sliding friction. The surface of the supporting part 221 away from the inner diameter adjusting ring 21 is curved to contact the inner wall of the steel strip coil and avoid the sharp edges from scratching the inner wall of the steel strip coil. The side of the supporting part 221 is provided with a limiting strip 2211. The cross-section of the limiting strip 2211 is rectangular and cooperates with the limiting groove 212 on the outer circumference of the inner diameter adjusting ring 21 to prevent the slider 22 from deflecting during movement.

[0043] The guide threaded post 23 passes through the center of the fixed base 1 and is perpendicular to the fixed base 1. The guide threaded post 23 guides and supports the inner diameter adjusting ring 21. The moving ring 24 abuts against the inner diameter adjusting ring 21, and its inner wall is threadedly connected to the guide threaded post 23. By rotating the moving ring 24, the moving ring 24 moves along the guide threaded post 23, which in turn pushes the inner diameter adjusting ring 21 to move along the guide threaded post 23. The guide threaded post 23 can be made of carbon steel or stainless steel, and its length is determined according to actual needs. The outer surface of the guide threaded post 23 is threaded with a lead of 5-8 mm to ensure that the inner diameter adjusting ring 21 can move smoothly when the moving ring 24 rotates. The moving ring 24 can be made of brass or aluminum alloy. Its inner wall is threaded to match the guide threaded post 23, and its outer wall is textured with anti-slip texture for easy manual operation.

[0044] The abutment plate 211 on the inner wall of the inner diameter adjusting ring 21 is sleeved on the guide thread post 23. The abutment plate 211 can effectively prevent the inner diameter adjusting ring 21 from deflecting during movement. The side of the moving ring 24 opposite to the abutment plate 211 is flush with the inner diameter adjusting ring 21. This design allows the moving ring 24 to be located inside the inner diameter adjusting ring 21, saving space and avoiding interference with the operation of the steel strip coil.

[0045] The baffle 3 is located on the side of the adjusting ring away from the fixed base 1, and abuts against the steel strip coil to prevent the steel strip coil from slipping off the guide threaded post 23. The baffle 3 is sleeved on the guide threaded post 23, and a fastener 4 is provided on the side away from the inner diameter adjusting ring 21. The fastener 4 is sleeved on the guide threaded post 23 and threadedly connected to the guide threaded post 23. A plug rod 41 is provided on the side of the fastener 4 facing the inner diameter adjusting ring 21. The plug rod 41 passes through the baffle 3 and engages with the plug hole 241 on the moving ring 24. By rotating the baffle 3, the moving ring 24 can be rotated, thereby realizing the movement of the inner diameter adjusting ring 21.

[0046] The baffle 3 can be made of aluminum alloy or magnesium alloy. Its surface has multiple weight-reducing through holes 31 arranged in a circumferential array. The design of the weight-reducing through holes 31 not only reduces the weight of the baffle 3 but also provides the operator with a fulcrum for rotating the baffle 3, facilitating operation. The insertion rod 41 is detachably connected to the fastener 4, which can be achieved through threads or other connection methods. When it is not necessary to use the baffle 3 to drive the moving ring 24 to rotate, the insertion rod 41 can be removed from the fastener 4 to avoid gaps between the baffle 3 and the steel strip coil.

[0047] The working principle of this application is as follows: When using the armored reel for steel strip coils, multiple sliders 22 jointly support the steel strip coils. The insert rod 41 is installed on the fastener 4 and passes through the baffle 3, engaging with the insertion hole 241 on the surface of the moving ring 24. The baffle 3 is rotated with the weight reduction through hole 31 as the force point. The insert rod 41 drives the moving ring 24 to rotate. During the rotation, the moving ring 24 slides along the extension direction of the guide thread post 23, thereby driving the inner diameter adjusting ring 21 to slide along the guide thread post 23. The inner diameter adjusting ring 21 drives the slider 22 to slide along the guide groove 11, thereby making multiple sliders 22 in close contact with steel strip coils of different inner diameters, thus enabling the bearing of steel strip coils of different inner diameters. Finally, the insert rod 41 is removed, allowing the baffle 3 to abut against the side of the steel strip coil to prevent the steel strip coil from falling off.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
