Description

Technical Field

[0001] This utility model relates to the field of steel coil processing technology, specifically to an automatic steel coil unwinding machine. Background Technology

[0002] Steel coils, also known as rolled steel, are steel products that are hot-pressed or cold-pressed into coils. To facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.), automatic uncoiling machines are used to unwind the steel coils from the rolls during the processing of steel coils.

[0003] For example, a steel coil uncoiling machine with announcement number CN220431682U and announcement date of 2024.02.02 includes a frame, a coil rotatably clamped on the frame, a clamping groove on the frame, a pressing component movably clamped in the clamping groove, an electric telescopic rod installed on the frame via a fixed platform, the telescopic end of the electric telescopic rod abutting against the pressing component; an assembly groove is provided on the coil, a limit component is provided in the assembly groove, and a positioning component is provided at the opening of the assembly groove.

[0004] In the existing technology, it is not possible to fix the steel coil roll quickly and conveniently, which results in a long time when fixing the steel coil roll to be unwound on the unwinding machine, resulting in slow unwinding efficiency of the steel coil. Therefore, there is an urgent need to design an automatic steel coil unwinding machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic steel coil unwinding machine to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic steel coil unwinding machine includes a stand, a guide seat, and a support seat. A fixed roller is rotatably connected to one side of the stand, and a top holding block is slidably connected inside the fixed roller. An anti-detachment plate is provided on the outer wall of the top holding block, and a spring connected to the anti-detachment plate is provided on the inner wall of the fixed roller. A long neck screw is threaded into one end of the fixed roller, and a pressing block and a rotating wheel are respectively provided at both ends of the long neck screw. A bearing seat is provided at one end of the fixed roller.

[0008] Furthermore, at the junction of the extrusion block and the top holding block, and with the rotating wheel located outside the fixed roller, a motor is fixedly installed on the inner wall of the stand, and one end of the fixed roller is installed on the output shaft of the motor.

[0009] Furthermore, a support block is rotatably connected inside the support base, and the support block is in contact with the bearing seat. A motor is fixedly installed on the outer wall of one side of the support base, and the support block is installed on the output shaft of the motor.

[0010] Furthermore, a feeding seat is slidably connected to the top of the guide seat, and movable wheels are rotatably connected to the outer walls on both sides of the feeding seat via bearings, and the movable wheels are tumbled inside the guide seat.

[0011] Furthermore, a transmission block is fixedly installed on the outer wall of the bottom of the feeding seat, and a second motor is fixedly installed on the inner wall of one side of the stand. A screw is installed on the output shaft of the second motor, and the transmission block is threadedly sleeved on the outside of the screw.

[0012] Furthermore, a hydraulic cylinder is fixedly installed on the inner wall of the bottom of the feeding seat, and a support is installed on the output end of the hydraulic cylinder, and a support block is fixedly installed on the outer wall of the top of the support.

[0013] Furthermore, a controller is fixedly installed on the outer wall of one side of the stand, and motors one, two, and three are electrically connected to the controller.

[0014] In the above technical solution, this utility model provides an automatic steel coil unwinding machine.

[0015] By using a fixed roller, a top holding block, an anti-detachment plate, a spring, a long neck screw, an extrusion block, and a rotating wheel, the rotating wheel drives the long neck screw to rotate, which in turn moves the top holding block to press against the inclined surface of the top holding block. This allows the top holding block to move outward from the fixed roller. Multiple top holding blocks can quickly and easily hold and fix the inner wall of the steel strip roller, making the fixing efficiency of the steel strip roller faster and thus improving the efficiency of unwinding the steel coil.

[0016] With the set bearing seat, support seat, support block and motor one, motor one can drive the support block to rotate, so that the support block rotates to the bottom of the bearing seat, which can support the bearing seat, improve the support force of the fixed roller on the steel strip roller, and prevent the fixed roller from being pressed down and tilted by the steel strip roller.

[0017] The system consists of a feeding seat, moving wheels, transmission block, motor 2, screw, support, support block, and hydraulic cylinder. Motor 2 drives the screw to rotate and thread the transmission block, which in turn moves the feeding seat to the fixed roller, thus achieving automatic feeding of the steel strip roller. Hydraulic cylinder 2 moves the support and support block upward, raising and lowering steel strip rollers with different steel strip thicknesses to different heights. This allows steel strip rollers with different steel strip thicknesses to be fitted over the fixed roller, making it very flexible to use. Attached Figure Description

[0027] This utility model provides an automatic steel coil unwinding machine, including a stand 1, a guide seat 10, and a support seat 11. A fixed roller 2 is rotatably connected to one side of the stand 1, and a top holding block 3 is slidably connected inside the fixed roller 2. An anti-detachment plate 4 is provided on the outer wall of the top holding block 3, and a spring 5 connected to the anti-detachment plate 4 is provided on the inner wall of the fixed roller 2. A long neck screw 6 is threaded into one end of the fixed roller 2, and a pressing block 7 and a rotating wheel 8 are respectively provided at both ends of the long neck screw 6. A bearing seat 9 is provided at one end of the fixed roller 2. The rotating wheel 8 drives the long neck screw 6 to rotate and push the pressing block 7 to move and press the top holding block 3, so that the top holding block 3 presses against the inner wall of the steel strip roller, which can quickly fix the steel strip roller.

[0028] By setting the rotating wheel 8 to drive the long neck screw 6 to rotate, the top holding block 3 moves and presses against the inclined surface of the top holding block 3, which can make the top holding block 3 move outward from the fixed roller 2. Multiple top holding blocks 3 can quickly and easily hold and fix the inner wall of the steel strip roller, and the efficiency of fixing the steel strip roller is faster, thereby improving the efficiency of unwinding the steel coil.

[0029] In one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the extrusion block 7 is connected to the top holding block 3, and the rotating wheel 8 is located outside the fixed roller 2. The inner wall of the stand 1 is fixedly equipped with a motor 23, and one end of the fixed roller 2 is set on the output shaft of the motor 23. The motor 23 can drive the fixed roller 2 to rotate.

[0030] In another embodiment provided by this utility model, such as Figure 1 As shown, a support block 12 is rotatably connected inside the support base 11, and the support block 12 is in contact with the bearing seat 9. A motor 13 is fixedly installed on the outer wall of one side of the support base 11, and the support block 12 is installed on the output shaft of the motor 13. The motor 13 can drive the support block 12 to rotate.

[0031] In another embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the top of the guide seat 10 is slidably connected to the loading seat 14, and the outer walls on both sides of the loading seat 14 are rotatably connected to the moving wheels 15 through bearings. The moving wheels 15 are tumbled inside the guide seat 10, which makes the loading seat 14 move more smoothly.

[0032] In one embodiment provided by this utility model, such as Figure 1 and Figure 3As shown, a transmission block 16 is fixedly installed on the outer wall of the bottom of the loading seat 14, and a motor 17 is fixedly installed on the inner wall of one side of the stand 1. A screw 18 is installed on the output shaft of the motor 17. The transmission block 16 is threaded onto the outside of the screw 18. The motor 17 can drive the screw 18 to rotate and the transmission block 16 to move, so that the transmission block 16 can drive the loading seat 14 to move.

[0033] In another embodiment provided by this utility model, such as Figure 1 and Figure 4 As shown, a hydraulic cylinder 21 is fixedly installed on the inner wall of the bottom of the loading seat 14, and a support 19 is installed on the output end of the hydraulic cylinder 21. A support block 20 is fixedly installed on the outer wall of the top of the support 19. The hydraulic cylinder 21 can drive the support 19 and the support block 20 to rise and fall.

[0034] In another embodiment provided by this utility model, such as Figure 1 As shown, a controller 22 is fixedly installed on the outer wall of one side of the stand 1, and motor 13, motor 27 and motor 323 are electrically connected to the controller 22. The controller 22 can control motor 13, motor 27 and motor 323.

[0035] Working principle: Place the steel strip roller on the support block 20 of the support 19. Turn on the motor 17 to drive the screw 18 to rotate the transmission block 16. This causes the transmission block 16 to move the feeding seat 14 towards the fixed roller 2. When the feeding roller moves to the end of the fixed roller 2, turn on the hydraulic cylinder 21 to move the support 19, the support block 20, and the steel strip roller upwards until the steel strip roller can be fitted over the fixed roller 2. Then turn on the motor 17 again to drive the screw 18 to rotate the transmission block 16. This causes the transmission block 16 to move the feeding seat 14 towards the outside of the fixed roller 2, so that the steel strip roller is fitted over the fixed roller 2. Hold the fixed roller 2 with one hand and use the other hand to... Rotating wheel 8 drives long-neck screw 6 to move extrusion block 7 to press against the inclined surface of top holding block 3, causing top holding block 3 to move towards the inner wall of steel strip roller and support the inner wall of steel strip roller, thus fixing steel strip roller on fixed roller 2. The feeding seat 14 is moved away from the upright seat 1. Motor 13 is turned on to drive support block 12 to rotate, so that support block 12 rotates to be located below bearing seat 9 and fits against the bottom outer wall of bearing seat 9, thus supporting the end of fixed roller 2 and preventing fixed roller 2 from being pressed down and tilted by steel strip roller, improving stability. Motor 23 is turned on to drive fixed roller 2 to rotate, thus automatically unwinding the steel strip on the steel strip roller fixed on fixed roller 2.
