Description

Technical Field

[0001] This application relates to the technical field of steel coil processing, and in particular to a steel coil feeding auxiliary strip removal device. Background Technology

[0002] Steel coils are metal products made by rolling steel into a coil shape. They are one of the core semi-finished or finished product forms in the steel industry. Steel coil production is based on continuous casting and rolling technology. High-temperature heated steel billets are rolled multiple times in a rolling mill to form strips of uniform thickness and fixed width, which are then coiled for easy storage, transportation, and subsequent processing.

[0003] A steel coil feeding auxiliary stripping device, disclosed on the Chinese Patent Network (publication number CN222224648U), includes: a base; a cutter with an inclined blade on one side, the distance between the inclined blade and the cutter axis gradually increasing from one end of the cutter to the other; and a power unit mounted on the base, with the cutter mounted on the drive end of the power unit at the end where the inclined blade is farther from the cutter axis. The power unit drives the cutter to move along the cutter axis. The base is installed on the rack of a three-in-one steel coil feeder, aligning the end of the cutter with the gap between the outer circumference of the steel coil and the binding strap. The power unit drives the cutter to move towards the gap between the outer circumference of the steel coil and the binding strap, cutting the binding strap under the action of the inclined blade. This reduces the safety hazards associated with manual cutting of binding straps and improves the safety of personnel operation.

[0004] The solution also has the following problems: the device does not have a buffer mechanism when the cutting blade contacts the steel coil. If the force is too great when it contacts the steel coil, the cutting blade may break. In addition, there is no limit to the steel coil, which will cause the steel coil to be stretched open during cutting. Therefore, there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a steel coil feeding auxiliary strip unwinding device. Utility Model Content

[0006] The purpose of this utility model is to provide a steel coil feeding auxiliary strip removal device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel coil feeding auxiliary strip removal device, comprising a support base, a fixed shaft vertically mounted on the outer side of the support base, four sets of first sliding grooves with the fixed shaft as the center of a circular array on the outer side of the support base around the fixed shaft, a sliding rod installed inside the first sliding groove, a slider slidably mounted on the outer ring surface of the sliding rod, a limiting roller extending in the same direction as the fixed shaft mounted outside the slider, and a fixing ear also mounted on the outer side of the support base away from the fixed shaft on the side of the limiting roller, the fixing ear being closer to the fixed shaft on the side with water... An electric telescopic rod is mounted on a flat surface. A fixed frame is mounted on the free end of the electric telescopic rod. A threaded rod is mounted between the inner sidewalls of the fixed frame. A movable frame is mounted on the outer ring surface of the threaded rod. The movable frame has symmetrical second sliding grooves at both ends away from the threaded rod. A return spring is mounted on the opposite ends of the second sliding groove. A movable block is mounted on the opposite end of each return spring. An adjusting rod is hinged to the outside of each movable block. A support plate is hinged to the end of each adjusting rod away from the movable block. A cutting blade is mounted on the outer side of the support plate away from the two adjusting rods.

[0008] Preferably, a first servo motor is embedded on the side of the support base away from the fixed axis. A rotating rod is mounted on the output shaft of the first servo motor. Connecting rods are hinged to both ends of the rotating rod. A connecting block is installed between two sliders on both sides of the support base. The two ends of the connecting rod are rotatably connected to the rotating rod and the connecting block, respectively.

[0009] Preferably, the outer ring surface of the slide bar is slidably connected to the inside of the slider, and the first servo motor and the fixed shaft are located on the same central axis.

[0010] Preferably, a second servo motor is installed at one end of the fixed frame. The output shaft of the second servo motor passes through the fixed frame and is connected to one end of the threaded rod. The outer ring surface of the threaded rod is threadedly connected to the inside of the movable frame.

[0011] Preferably, the outer side of the movable block is slidably connected to the inside of the second slide groove, and both ends of the adjusting rod are rotatably connected to the movable block and the support plate.

[0012] Preferably, a telescopic rod is installed on the outside of the movable frame and between the two second slide grooves, and the end of the telescopic rod away from the movable frame is connected to the support plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This steel coil feeding auxiliary strip removal device uses a first servo motor output shaft to drive a rotating rod to rotate. When the rotating rod rotates, the connecting rod pushes the connecting block to move radially, driving the slider to slide synchronously along the sliding rod. This ensures that the four limit rollers always maintain equidistant contact with the outer circle of the steel coil, thereby limiting the movement of the steel coil. When the cutting blade contacts the outside of the steel coil, it will squeeze the support plate, which in turn squeezes the movable block to slide inside the second slide groove and compresses the return spring through two sets of adjusting rods. This buffers the cutting blade and prevents it from breaking if the contact force is too great. The device is easy to operate and has better practicality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0021] A steel coil feeding auxiliary strip removal device, as described in the following figure Figure 1 - Figure 4The system includes a support base 1, with a fixed shaft 2 vertically mounted on its outer surface. Four sets of first sliding grooves 101, centered on the fixed shaft 2, are formed on the outer surface of the support base 1 around the fixed shaft 2. A sliding rod 3 is installed inside each first sliding groove 101. A slider 4 is slidably mounted on the outer ring surface of the sliding rod 3. A limiting roller 5, extending in the same direction as the fixed shaft 2, is mounted on the outside of the slider 4. A fixing ear 6 is also mounted on the outer surface of the support base 1 on the side of the limiting roller 5 away from the fixed shaft 2. An electric telescopic rod 7 is horizontally mounted on the side of the fixing ear 6 closest to the fixed shaft 2. A mounting plate is installed on the free end of the electric telescopic rod 7. A fixed frame 8 is provided, and a threaded rod 9 is installed between the inner side walls of the fixed frame 8. A movable frame 10 is installed on the outer ring surface of the threaded rod 9. The movable frame 10 has two symmetrical second slide grooves 1001 on the side away from the threaded rod 9. A return spring 11 is installed on the opposite ends of the second slide groove 1001. A movable block 12 is installed on the opposite end of the return spring 11. An adjusting rod 13 is hinged to the outside of the movable block 12. A support plate 14 is hinged to the end of the adjusting rod 13 away from the movable block 12. A cutting blade 15 is installed on the side of the support plate 14 away from the two adjusting rods 13.

[0022] Reference Figure 1 - Figure 2 A first servo motor 16 is embedded on the side of the support base 1 facing away from the fixed shaft 2. A rotating rod 17 is mounted on the output shaft of the first servo motor 16. Connecting rods 18 are hinged to both ends of the rotating rod 17. A connecting block 19 is installed between the two sliders 4 on both sides of the support base 1. The two ends of the connecting rod 18 are rotatably connected to the rotating rod 17 and the connecting block 19, respectively. The output shaft of the first servo motor 16 drives the rotating rod 17 to rotate. When the rotating rod 17 rotates, the connecting rod 18 pushes the connecting block 19 to move radially, driving the slider 4 to slide synchronously along the slide bar 3, ensuring that the four limiting rollers 5 always maintain equidistant contact with the outer circle of the steel coil, thereby achieving the limitation of the steel coil. The outer ring surface of the slide bar 3 is slidably connected to the inside of the slider 4. The first servo motor 16 and the fixed shaft 2 are located on the same central axis. The first servo motor 16 and the fixed shaft 2 are coaxially designed to eliminate the inability of the four limiting rollers 5 to fit and limit the outside of the steel coil due to center offset.

[0023] Reference Figure 3 - Figure 4 A second servo motor 20 is installed at one end of the fixed frame 8. The output shaft of the second servo motor 20 passes through the fixed frame 8 and is connected to one end of the threaded rod 9. The outer ring surface of the threaded rod 9 is threadedly connected to the inside of the movable frame 10. The second servo motor 20 drives the threaded rod 9 to rotate, and the movable frame 10 is translated axially along the fixed frame 8 through the threaded connection, thereby driving the cutting blade 15 to cut the cable ties on the outside of the steel coil.

[0024] Reference Figure 3 - Figure 4 The outer side of the movable block 12 is slidably connected to the interior of the second slide groove 1001. Both ends of the adjusting rod 13 are rotatably connected to the movable block 12 and the support plate 14. A telescopic rod 21 is installed on the outside of the movable frame 10 and between the two second slide grooves 1001. The end of the telescopic rod 21 away from the movable frame 10 is connected to the support plate 14. When the cutting blade 15 contacts the outside of the steel coil, it will squeeze the support plate 14, thereby squeezing the movable block 12 inside the second slide groove 1001 and compressing the return spring 11 through the two sets of adjusting rods 13. The telescopic rod 21 plays a fixed guiding role, thereby buffering the cutting blade 15 and preventing the cutting blade from breaking if the contact force is too large.

[0025] The implementation principle of the steel coil feeding auxiliary strip removal device in this embodiment is as follows: During the strip removal process of the steel coil, the take-up roller of the steel coil is first placed on the fixed shaft 2. The output shaft of the first servo motor 16 drives the rotating rod 17 to rotate. When the rotating rod 17 rotates, the connecting rod 18 pushes the connecting block 19 to move radially, driving the slider 4 to slide synchronously along the sliding rod 3, ensuring that the four limiting rollers 5 always maintain equidistant contact with the outer circle of the steel coil, thereby achieving the limitation of the steel coil. The first servo motor 16 is coaxial with the fixed shaft 2, eliminating the inability of the four limiting rollers 5 to fit and limit the outer circle of the steel coil due to center offset. The electric telescopic rod 7 can be used to... The cutting blade 15 is brought close to the cable ties on the steel coil. The second servo motor 20 drives the threaded rod 9 to rotate. The movable frame 10 is axially translated along the fixed frame 8 through a threaded connection, thereby driving the cutting blade 15 to cut the cable ties on the outside of the steel coil. When the cutting blade 15 contacts the outside of the steel coil, it will squeeze the support plate 14. This will cause the movable block 12 to slide inside the second slide groove 1001 and compress the return spring 11 through the two sets of adjusting rods 13. The telescopic rod 21 plays a fixed guiding role, thereby buffering the cutting blade 15 and preventing it from breaking if the contact force is too large. The operation is convenient and the practicality is better.
