[0039] Please see Figure 1-3 The present invention provides a technical solution for a cored winding device:

[0040] A cored coiling device includes a three-roll bending mechanism and a coiling mechanism. The three-roll bending mechanism and the coiling mechanism are arranged sequentially along the conveying direction of the metal coil. The metal coil is first bent by the three-roll bending mechanism and then conveyed to the coiling mechanism to complete the coiling process.

[0041] I. Specific Structure of the Three-Roll Bending Mechanism

[0042] The three-roll bending mechanism includes a three-roll bending mechanism frame 24 and a motor base 34. The three-roll bending mechanism frame 24 is a frame structure used to support the bending roller assembly, the roll adjustment assembly, and the roll centering limiter assembly. The motor base 34 is fixedly installed on the ground or equipment installation platform and is used to install the three-roll bending mechanism drive motor 32 and the transmission box 35.

[0043] The bending roller assembly includes bending roller 18, bending roller 29 and bending roller 37. All three are rotatably mounted on the top of the three-roll bending mechanism frame 24 via bearings and are arranged in parallel along the roll material conveying direction. The roll material enters from above bending roller 18, passes under bending roller 29 and above bending roller 3 in sequence. The conveying of the roll material and the three-roll bending mechanism are realized through the coordinated rotation of the three rollers.

[0044] The three-roll bending mechanism drive motor 32 is a servo motor, and its output shaft is connected to the input end of the transmission box 35 via a coupling 33. The transmission box 35 contains three meshing cylindrical gears with the same number of teeth to ensure consistent output speed. Each gear's shaft extends outward to form an output end, and the input end of the transmission box 35 is connected to the shaft of one of the gears. The three output ends of the transmission box 35 are connected to one end of transmission shaft 29, transmission shaft 36, and transmission shaft 38 via universal couplings 33. The other ends of transmission shafts 29, 36, and 38 are then connected to the ends of bending rollers 18, 19, and 27 via universal couplings 33. During operation, the three-roll bending mechanism drive motor 32 starts, driving the three output ends to rotate synchronously via the gears inside the transmission box 35. This, in turn, drives bending rollers 18, 19, and 27 to rotate synchronously via the transmission shaft assembly, achieving smooth conveying of the roll material.

[0045] The reel adjustment assembly includes a reel adjustment motor 22, a screw jack 23, a reel adjustment motor 28, and a screw jack 25. Two sets of reel adjustment motors 22 and 23 are symmetrically arranged on both sides of the bottom of the three-roll bending mechanism frame 24. The output end of the reel adjustment motor 22 is connected to the drive end of the screw jack 23 via a coupling, and the telescopic end of the screw jack 23 is rotatably connected to the end of the bending roller 18 via a bearing seat. Similarly, two sets of reel adjustment motors 28 and 25 are also symmetrically arranged on both sides of the bottom of the three-roll bending mechanism frame 24. The output end of the reel adjustment motor 28 is connected to the drive end of the screw jack 25 via a coupling, and the telescopic end of the screw jack 25 is rotatably connected to the end of the bending roller 19 via a bearing seat. During operation, by controlling the forward and reverse rotation of the roller adjustment motor 22, the telescopic end of the screw jack 23 can be driven to rise and fall, thereby adjusting the height of both ends of the bending roller 18 and realizing the adjustment of the tilt angle of the bending roller 18; similarly, the tilt angle of the bending roller 19 can be adjusted by the roller adjustment motor 28 to adapt to the bending requirements of the roll material with different curvature requirements.

[0046] The roll material centering limiter assembly includes two symmetrically arranged width adjusting cylinders 37 and width limiting wheels 39. The two sets of width adjusting cylinders 37 are horizontally fixedly mounted on both sides of the top of the three-roll bending mechanism frame 24, with their telescopic ends facing each other. The width limiting wheels 39 are mounted on the telescopic ends of the corresponding width adjusting cylinders 37 via wheel seats, and the width limiting wheels 39 can rotate around the wheel seats. According to the width of the roll material to be processed, the telescopic amount of the width adjusting cylinders 37 is controlled, driving the width limiting wheels 39 on both sides to move closer or further apart, so that the distance between the width limiting wheels 39 on both sides matches the width of the roll material, thereby achieving width limiting during the roll material conveying process and preventing roll material deviation.

[0047] II. Specific Structure of the Coiling Mechanism

[0048] The curling mechanism includes a frame 1, which is a welded frame structure and is fixedly installed on the ground. The top of the frame is equipped with a lateral adjustment component, which is used to drive the lateral sliding seat 4 to move laterally.

[0049] The lateral adjustment assembly includes a first lateral adjustment cylinder 21 and a second lateral adjustment cylinder 26. The first lateral adjustment cylinder 21 is horizontally mounted on one side of the top of the frame 1, and its telescopic end is fixedly connected to one side of the lateral sliding seat 4 via a flange. The second lateral adjustment cylinder 26 is horizontally mounted on the other side of the top of the frame 1, and its top is equipped with a lateral slide rail. The lateral slider 3 slides in cooperation with the lateral slide rail, and the lateral slider 3 is fixedly connected to the other side of the lateral sliding seat 4 via bolts. Through the telescopic drive of the first lateral adjustment cylinder 21, combined with the guiding action of the lateral slider 3 and the lateral slide rail, the lateral sliding seat 4 can be driven to move smoothly laterally.

[0050] A vertical adjustment assembly is mounted on the top of the horizontal sliding seat 4. The vertical adjustment assembly includes a vertical support 6, a vertical slide rail 8, a vertical slider 5, and a vertical adjustment cylinder 12. The vertical adjustment cylinder 12 is equipped with a control valve and a displacement sensor is installed on the vertical track to achieve precise height control of the rolled material. The vertical support 6 is fixedly mounted on the top of the horizontal sliding seat 4 by bolts. The vertical slide rail 8 is fixedly installed on one side of the vertical support 6. The vertical slider 5 is slidably connected to the vertical slide rail 8 and is fixedly connected to the lifting seat 40 by bolts. A top support 11 is mounted on the top of the vertical support 6 by bolts. The vertical adjustment cylinder 12 is vertically mounted on the top of the top support 11, and its telescopic end passes through the top support 11 and is fixedly connected to the top of the lifting seat 40. Driven by the extension and retraction of the vertical adjustment cylinder 12, and guided by the vertical slider 5 and the vertical slide rail 8, the lifting seat 40 can be driven to rise and fall smoothly in the vertical direction. As the diameter of the roll material increases, the lifting seat 40 rises continuously to avoid the roll material from bumping or hitting.

[0051] A tensioning roller 7 is rotatably mounted on the lifting base 40 via bearings. The end of the tensioning roller 7 is equipped with a chuck for clamping the end of the metal coil. A winding motor 30 and a tension adjusting cylinder 31 are bolted to the back of the lifting base 40. The winding motor 30 is a servo motor, and its output end is connected to one end of the tensioning roller 7 via a synchronous belt or gearbox to drive the tensioning roller 7 to rotate and realize the winding and coiling of the coil. The tension adjusting cylinder 31 is horizontally mounted, and its extension end is connected to the opening and closing drive end of the tensioning roller 7 via a rotating shaft. By extending and retracting the tension adjusting cylinder 31, the tension of the tensioning roller 7 can be adjusted to ensure the tightness of the coil during winding. After winding is completed, the tensioning roller 7 can be released by resetting the tension adjusting cylinder 31, making it easy to unwind the coil.

[0052] The transverse sliding seat 4 is also equipped with a clamping assembly for clamping the roll material. The clamping assembly includes a cylinder mounting seat 12, a clamping cylinder 17, a clamping arm mounting seat 16, a clamping arm 15, a cylinder mounting seat 24, a clamping cylinder 23, a clamping frame 10, and a pressure roller 9. The clamping arm mounting seat 16 is fixedly connected to the lifting seat 40 by bolts. The bottom end of the clamping cylinder 17 is hinged to the clamping arm mounting seat 16 through the cylinder mounting seat 12. The middle part of the clamping arm 15 is rotatably connected to the top end of the clamping arm mounting seat 16 through a pin. The telescopic end of the clamping cylinder 17 is hinged to one end of the clamping arm 15 through a pin. By driving the telescopic movement of the clamping cylinder 17, the clamping arm 15 can be rotated around the pin in the middle, thereby realizing the lifting and lowering adjustment of the other end of the clamping arm 15.

[0053] The second clamping cylinder 13 is mounted on the top of the clamping arm 15 via the second cylinder mounting seat 14, and the clamping frame 10 is rotatably mounted on the other end of the clamping arm 15 via a pin. Multiple pressure rollers 9 are evenly arranged along the width of the roll material and are mounted on one end of the clamping frame 10 via axles. The telescopic end of the second clamping cylinder 13 is hinged to the other end of the clamping frame 10 via a pin. Driven by the telescopic movement of the second clamping cylinder 13, the clamping frame 10 can rotate around its hinge point with the clamping arm 15, thereby adjusting the clamping force of the pressure rollers 9 on the roll material, ensuring that the pressure rollers 9 always fit tightly against the roll material surface, and preventing the roll material from loosening during the winding process.

[0054] III. Operating Principle of this Device

[0055] The specific operating procedure of this core-curling device is as follows:

[0056] (1) Pre-processing adjustment: According to the width of the metal coil to be processed, control the operation of the width adjustment cylinder 37 of the coil centering limiter assembly to drive the width limit wheels 39 on both sides to move to the preset position to ensure that the distance between the width limit wheels 39 on both sides is adapted to the width of the coil; at the same time, according to the requirements of the three-roll bending mechanism of the coil, control the operation of the first winding adjustment motor 22 and the second winding adjustment motor 28, and adjust the tilt angle of the first bending roller 18 and the second bending roller 19 through the first screw jack 23 and the second screw jack 25. As the coil is continuously wound up, the curvature of the coil bending is continuously reduced. Through adjustment, the coils are more closely fitted together.

[0057] (2) Coil feeding and pre-bending: The starting end of the metal coil is passed over the top of bending roller 18, the bottom of bending roller 29, and the top of bending roller 37 in sequence. The three-roll bending mechanism drive motor 32 is started, and the bending roller 18, bending roller 29, and bending roller 37 are driven to rotate synchronously through the transmission box 35 and the transmission shaft assembly, which drives the coil to be conveyed to the coiling mechanism. In this process, the precise bending of the coil arc is completed.

[0058] (3) Curling and winding: The end of the bent metal coil is clamped and fixed by the clamp at the end of the tensioning roller 7; during winding, the curling mechanism is located above the three-roller bending mechanism. The coil motor 30 is started to drive the tensioning roller 7 to rotate and begin to curl and wind the metal coil; as the curling process proceeds, the diameter of the metal coil gradually increases. At this time, the vertical adjustment cylinder 12 is controlled to move, driving the lifting seat 40 to move smoothly upward along the vertical slide rail 8. At the same time, the pressing cylinder 17 and pressing cylinder 2 13 of the pressing assembly are controlled to work together to ensure that the pressure roller 9 always fits tightly against the surface of the coil and applies a stable pressing force to the coil to prevent the coil from loosening.

[0059] (4) Unwinding complete: When the roll material is wound up to the preset diameter, the roll material motor 30 stops working; control the tension adjustment cylinder 31 to drive the tension roll material roller 7 to reset and loosen; then control the lateral adjustment cylinder 21 to drive the lateral sliding seat 4 and the wound roll material to move laterally to the preset position of the feeding trolley; finally, loosen the clamp on the tension roll material roller 7, place the roll material on the feeding trolley, and complete the entire unwinding process.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention, achieved through conventional substitutions or by achieving the same function without departing from the principles and spirit of the present invention, fall within the scope of protection of the present invention.
