Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of light steel keel corner processing equipment, specifically, to an automatic corner unloading machine for light steel keels. Background Technology

[0002] In the construction industry, light steel keel is widely used in interior decoration of hotels, airport terminals, train stations, shopping malls, factories, office buildings and other places due to its light weight, high strength and adaptability to waterproofing, shock resistance, dustproofing, sound insulation, sound absorption and constant temperature. It is especially used for the decorative design of non-load-bearing walls and building roofs with lightweight boards such as paper-faced gypsum board and decorative gypsum board.

[0003] Light steel keel is typically made from high-quality continuous hot-dip galvanized steel strip, rolled using a cold bending process. The uncoiling and pre-treatment of the steel coil are crucial in the production of light steel keel corner products. However, existing uncoiling machines have significant drawbacks in handling the uncoiling of steel coils for light steel keel corners. Due to uneven internal stress distribution during production, transportation, and storage, and the potential impact of compression and collisions, it is difficult to flatten the steel coil during uncoiling. Unflattened coils can compromise the dimensional accuracy of the light steel keel during subsequent processing, easily leading to bending, twisting, and other shape defects. This not only affects the appearance quality of the light steel keel but may also reduce its mechanical properties, such as load-bearing capacity and stability, ultimately impacting the safety and reliability of the final building structure.

[0036] like Figures 1-5 As shown, it illustrates an automatic corner feeding machine for light steel keel according to an embodiment of the present disclosure, comprising:

[0037] The base plate 1 and the bracket 2 are fixed on the base plate 1.

[0038] The front frame 3 and the conveying assembly 6 are fixed on the surface of the base plate 1, and the conveying assembly 6 is mounted on the front frame 3.

[0039] Leveling component 5 is mounted on bracket 2;

[0040] Install the unwinding assembly 4, which is set on the surface of the base plate 1;

[0041] The unwinding assembly 4 includes a fixed frame 4-1, which is fixed to the surface of the base plate 1. A central shaft 4-2 is fixedly connected to the side surface of the fixed frame 4-1. An unwinding reel frame 4-3 is rotatably connected to the central shaft 4-2. A protective cover 4-4 is fixedly connected to the side surface of the fixed frame 4-1. The unwinding reel frame 4-3 is rotatably connected inside the protective cover 4-4. A discharge port 4-5 is opened on the side surface of the protective cover 4-4. A notch 4-6 is opened at the bottom of the protective cover 4-4. A telescopic cylinder 4-7 is provided on the surface of the base plate 1. A connecting frame 4-8 is provided at the output end of the telescopic cylinder 4-7. A pair of pulleys 4-9 are rotatably connected to the side end face of the connecting frame 4-8. A side support wheel 4-10 is rotatably connected to the bottom of the connecting frame 4-8.

[0042] In some examples, to achieve stable unwinding of the steel coil, an unwinding assembly 4 is designed. This assembly includes a fixing frame 4-1 fixed to the surface of the base plate 1. The fixing frame 4-1 is a basic support structure. A central shaft 4-2 is fixedly connected to the side surface of the fixing frame 4-1 and rotatably connected to an unwinding reel frame 4-3. The steel coil can be fitted onto the unwinding reel frame 4-3, and the material is unwound by rotation. A protective cover 4-4 is fixedly connected to the side surface of the fixing frame 4-1 to provide protection for the steel coil. The unwinding reel frame 4-3 is rotatably connected inside the protective cover 4-4, and the material is discharged outward from the discharge port 4-5 opened on the side surface of the protective cover 4-4. The unwinding process is designed to ensure orderly unwinding. The bottom of the protective cover 4-4 has a notch 4-6. A telescopic cylinder 4-7 is installed on the base plate 1 and is located directly below the notch 4-6. A connecting frame 4-8 is fixed to the output end of the telescopic cylinder 4-7. A pair of pulleys 4-9 are rotatably connected to the side end face of the connecting frame 4-8. These pulleys can support the bottom of the unwinding tray 4-3 during the unwinding process, providing support force and making the steel coil rotate more smoothly. The side support wheel 4-10 is rotatably connected to the bottom of the connecting frame 4-8, which can support the steel coil from the side, enhancing its stability and ensuring that the steel coil will not tilt or shake during the telescopic process, making the entire unwinding process stable and efficient.

[0043] like Figures 1-5 As shown, this embodiment proposes a leveling component 5 including a pair of second cylinders, which are respectively installed on the top and bottom of the bracket 2. The output end of the second cylinder is connected to a rectangular plate 5-2. A pair of round rods 5-3 are provided on the surface of the rectangular plate 5-2. The round rods 5-3 are movably connected to the bracket 2. Side openings 5-3 are provided on both ends of the rectangular plate 5-2. Leveling rollers 5-5 are rotatably connected to both sides of the rectangular plate 5-2. A pair of elongated holes 5-6 are provided on the top and bottom of the bracket 2. A straightening roller 5-7 is slidably connected between the pair of opposite elongated holes 5-6. The top and bottom of the straightening roller 5-7 are connected to fixing nuts 5-8 by threaded screws. The straightening roller 5-7 is located inside the side openings 5-3.

[0044] In some examples, a leveling component 5 is designed to achieve the effect of leveling the steel coil during conveying. This component includes two second cylinders, which are respectively installed at the top and bottom of the support 2. The second cylinders are the basic structure, and their output ends are connected to a rectangular plate 5-2. The overall size of the rectangular plate 5-2 is larger than the width of the steel coil. When the second cylinders are activated, they can control the lifting and lowering of the rectangular plate 5-2. A pair of round rods 5-3 are provided on the surface of the rectangular plate 5-2 and are movably connected to the support 2. The round rods 5-3 play a guiding and supporting role to ensure that the rectangular plate 5-2 remains stable during movement. Notches 5-44-6 are opened on both ends of the rectangular plate 5-2, and leveling rollers 5-5 are rotatably connected to the other two sides. The rectangular plate 5-2 is pressed against both sides of the steel coil by the leveling rollers 5-5. During the conveying of the steel coil... It can perform rolling and leveling. The top and bottom of the support 2 are provided with a pair of elongated holes 5-6. A straightening roller 5-7 is slidably connected between the pair of opposite elongated holes 5-6. The straightening roller 5-7 can be adjusted in position within the elongated holes 5-6 according to the actual width of the steel coil. The straightening roller 5-7 can be pushed against both sides of the steel coil to ensure that the steel coil moves in the correct position without skewing. The top and bottom of the straightening roller 5-7 are connected with fixing nuts 5-8 by threaded screws to fix it after the position of the straightening roller 5-7 is adjusted, ensuring the stability of the straightening effect. The straightening roller 5-7 is located in the side opening 5-3 of the rectangular plate 5-2 and works in conjunction with the leveling roller 5-5. After the leveling roller 5-5 flattens the surface of the steel coil, the cooperation of the two makes the material achieve the ideal flatness, meeting the requirements of subsequent processing or use of the equipment.

[0045] like Figures 1-5 As shown, this embodiment proposes a conveying assembly 6 including a pair of conveying rollers 6-1, both of which are rotatably connected to the front frame 3. One end of each conveying roller 6-1 is provided with a transmission gear 6-2, which mesh with each other. One of the conveying rollers 6-1 is controlled to rotate by a motor.

[0046] In some examples, in order to achieve the effect of stable steel coil conveying, a conveying assembly 6 is designed. This assembly includes a pair of conveying rollers 6-1 and is rotatably connected in the front frame 3. One end of each conveying roller 6-1 is provided with a transmission gear 6-2 and they mesh with each other. The two conveying rollers 6-1 can be rotated synchronously through the transmission gear 6-2. One of the conveying rollers 6-1 is controlled to rotate by a motor, which can stably convey the steel coil.

[0047] For example, such as Figure 1 As shown, the surface of the conveyor roller 6-1 is an anti-slip structure.

[0048] In some examples, the anti-slip structural surface increases the friction with the steel coil surface, preventing slippage.

[0049] For example, such as Figure 5As shown, both ends of the connecting frame 4-8 are bent upwards, and a pair of pulleys 4-9 are attached to the surface of the unwinding frame 4-3.

[0050] In some examples, by bending the two ends of the connecting frame 4-8 upwards, the two pulleys 4-9 can be tilted at an angle, making it easier to simultaneously fit against the surface of the reel holder 4-3.

[0051] For example, such as Figure 2 As shown, the height of the discharge port 4-5 is at the same height as the axis of the unwinding reel.

[0052] In some examples, using the same height ensures that the steel coil is horizontal after being released, facilitating leveling and transport.

[0053] In actual use: The steel coil is placed on the unwinding reel frame 4-3. The telescopic cylinder 5-14-7 is activated to raise the connecting frame 4-8. The pulley 4-9 is in contact with the bottom of the unwinding reel frame 4-3, and the side support wheel 4-10 supports the steel coil from the side. The steel coil is released from the discharge port 4-5. When it passes through the leveling component 5, the second cylinder is activated to adjust the height of the rectangular plate 5-2 so that the leveling roller 5-5 presses on the steel coil. At the same time, the position of the straightening roller 5-7 is adjusted and fixed according to the width of the steel coil. The steel coil is leveled under the action of the leveling roller 5-5 and the straightening roller 5-7. Then, the motor of the conveying component 6 drives one conveying roller 6-1 to rotate. Through the transmission gear 6-2, the two conveying rollers 6-1 rotate synchronously, conveying the leveled steel coil to the subsequent processing position.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
