Description

Technical Field

[0001] The invention relates to the technical field of steel strip production, and in particular to a copper-plated steel strip winding device. Background Art

[0002] Steel strip is a thin steel strip obtained by rolling, physical and chemical surface treatment of thicker raw steel strip. The most efficient steel strip production line on the market is to continuously unwind the rolled raw steel strip, and the raw steel strip continuously passes through the pre-arranged processing equipment to finally obtain a thin steel strip that meets the requirements, and then reel it up to obtain the finished product. In the step of reeling the steel strip, the common winding roller winding method is adopted, that is, the steel strip is rolled into a roll by continuous winding of a continuously rotating winding roller, wherein one end of the winding roller is connected to a power mechanism to drive the winding roller to rotate, and the other end is suspended to facilitate the removal of the rolled product steel strip from the winding roller.

[0003] The patent application document with publication number CN117383309A discloses a winding device for steel strip packaging, including a supporting base plate, a supporting ring frame fixedly connected to the top of the supporting base plate, a motor fixedly connected to the upper part of the supporting ring frame, a winding roller clamped on the output shaft of the motor, a winding transmission mechanism is arranged on the motor, a winding guide mechanism is arranged on the supporting base plate, and the winding guide mechanism is connected to the winding transmission mechanism. When in use, the motor is started, the winding roller winds the steel strip, the squeezing convex rod presses the steel strip, and the tension of the steel strip can be adjusted so that the winding roller can better wind the steel strip, and the guide groove wheel can guide the steel strip during the winding process, so that the steel strip on the winding roller is more evenly distributed, and the wound steel strip is not easy to loosen.

[0004] In the process of winding the steel strip, in order to avoid wear on the side of the steel strip, most related technologies use a suspended method to wind the steel strip, that is, the side of the steel strip does not contact the supporting structure. However, as the amount of steel strip wound on the outer side of the winding roller gradually increases, the self-weight of the steel strip may cause the wound part of the steel strip to collapse downward due to lack of support, affecting the winding effect of the steel strip. Summary of the invention

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 6 As shown, a copper-plated steel strip winding device of the present invention comprises a frame 1, on which a winding mechanism, a clamping mechanism and a supporting mechanism are provided.

[0031] The winding mechanism includes a winding roller 2 and a driving assembly. The winding roller 2 is longitudinally rotatable and is arranged on the frame 1. The winding roller 2 is formed by a plurality of arc plates 21. Each arc plate 21 can move along the radial direction of the winding roller 2. A driving structure 1 is provided on the frame 1 for driving the plurality of arc plates 21 to move synchronously along the radial direction of the winding roller 2 to change the effective diameter of the winding roller 2. The driving assembly is used to drive the winding roller 2 to rotate around its own axis to wind up the steel strip 5.

[0032] Specifically, Figures 1 to 3 As shown, by driving the multiple arc plates 21 to move synchronously in the direction away from the axis of the winding roller 2 through the driving structure 1, the effective diameter of the winding roller 2 can be increased. At this time, there is a gap between two adjacent arc plates 21. One end of the steel strip 5 to be wound is inserted into the gap between the two arc plates 21 and fixed. Then, the driving component drives the winding roller 2 to rotate, so that the steel strip 5 can be gradually wound on the outside of the winding roller 2, and the inner wall of the steel strip 5 is tightly against the outer wall of the winding roller 2. After the winding is completed, the driving structure 1 drives the multiple arc plates 21 to move synchronously in the direction close to the axis of the winding roller 2, so as to reduce the effective diameter of the winding roller 2. At this time, the outer wall of the winding roller 2 is separated from the inner wall of the steel strip 5, so that the wound steel strip 5 can be taken off from one end of the winding roller 2.

[0033] The clamping mechanism includes multiple groups of clamping components, and the multiple groups of clamping components are arranged in a circumferential array along the winding roller 2. In the present embodiment, the clamping components are provided in two groups, and the two groups of clamping components are symmetrically arranged on both sides of the winding roller 2. Each group of clamping components includes a clamping roller 31, and an elastic member 32 is provided between the clamping roller 31 and the frame 1. The clamping roller 31 can move according to the thickness of the steel strip 5 wound on the outer side of the winding roller 2, so that the side wall of the clamping roller 31 remains in contact with the steel strip 5.

[0034] Specifically, Figures 1 to 3 As shown, in the initial state, the clamping roller 31 is close to the side wall of the winding roller 2 under the action of the elastic member 32. As the thickness of the steel strip 5 wound on the outer side of the winding roller 2 gradually increases, the clamping roller 31 will be squeezed to move away from the winding roller 2. In this process, the clamping roller 31 is always in contact with the outer wall of the steel strip 5 under the action of the elastic member 32, which effectively reduces the gap between the wound steel strips 5, making the steel strip 5 on the winding roller 2 more evenly and tightly distributed, thereby making the wound steel strip 5 not easy to loosen, ensuring the winding effect.

[0035] The support mechanism includes a support plate 41, a plurality of support blocks 42 and a second drive structure. The support plate 41 is rotatably arranged at the lower end of the winding roller 2 and can rotate synchronously with the winding roller 2. Each support block 42 is in an arc shape. The support plate 41 is provided with a plurality of slide grooves that are adapted to the shape of the support block 42. Each support block 42 is longitudinally slidably matched with the support plate 41 through the corresponding slide groove, and the plurality of support blocks 42 are distributed on the support plate 41 in a spiral shape. The second drive structure is used to drive the plurality of support blocks 42 to move upward from the inside to the outside in sequence during the winding process of the steel strip 5, and to contact the part of the wound steel strip 5 to support the steel strip 5.

[0036] Specifically, Figures 1 to 4As shown, when the steel strip 5 is wound on the outside of the winding roller 2 in a bottom-suspended manner, the steel strip 5 may collapse downward due to its own weight and other reasons, affecting the final winding effect. By setting a supporting mechanism, as the steel strip 5 wound on the outside of the winding roller 2 gradually increases, the multiple support blocks 42 on the support plate 41 can be driven by the driving structure 2 to move upward from the inside to the outside in sequence to support the part of the wound steel strip 5. That is, every time the steel strip 5 wound on the outside of the winding roller 2 increases in thickness to a certain extent, a support block 42 will move upward to support the newly wound part of the steel strip 5, which can prevent the part of the wound steel strip 5 from collapsing downward. At the same time, the support block 42 moving upward only contacts the part of the wound steel strip 5, and does not It will contact with the unwound steel strip 5, thereby avoiding wear on the unwound steel strip 5. In addition, if multiple support blocks 42 are distributed in a ring shape on the support plate 41, there will be a certain gap between the two adjacent support blocks 42 inside and outside, so that the part of the steel strip 5 corresponding to this gap is still lacking support, thereby affecting the support effect on the steel strip 5. In this embodiment, multiple support blocks 42 are distributed in a spiral shape, so that the distance between any part of each support block 42 and the axis of the winding roller 2 is different, so that each layer of steel strip 5 wound on the outside of the winding roller 2 can contact with the corresponding support block 42 on the lower side, ensuring the support effect on the steel strip 5, and then ensuring the winding effect of the steel strip 5.

[0037] In some embodiments, driving structure 1 includes an electric push rod 22 and multiple connecting rods 23. The electric push rod 22 is rotatably arranged on the frame 1, and the output end extends vertically upward. The multiple connecting rods 23 are respectively arranged corresponding to the multiple arc plates 21. One end of each connecting rod 23 is hinged to the output end of the electric push rod 22, and the other end is hinged to the inner arc surface of the corresponding arc plate 21.

[0038] Specifically, Figures 1 to 3 As shown, starting the electric push rod 22 causes the output end of the electric push rod 22 to extend upward, which can drive the connecting rod 23 hinged to the output end to flip, so that the arc plate 21 hinged at the other end of the connecting rod 23 moves in the direction away from the electric push rod 22. Through the synchronous movement of multiple arc plates 21, the effective diameter of the winding roller 2 can be increased. Starting the electric push rod 22 causes the output end of the electric push rod 22 to shrink downward, which can drive the connecting rod 23 to flip in the opposite direction, so that the arc plate 21 moves in the direction close to the electric push rod 22, so as to reduce the effective diameter of the winding roller 2. By changing the effective diameter of the winding roller 2, the operation of removing the steel strip 5 can be made more efficient and convenient.

[0039] In some embodiments, the driving assembly includes a rotating plate 11, a synchronizer 12, a synchronizer 13 and a driving member 14. The rotating plate 11 is rotatably arranged on the frame 1. The synchronizer 12 is connected between the rotating plate 11 and the support plate 41 so that the two can rotate synchronously. The electric push rod 22 is arranged on the rotating plate 11. The outer side of the output end of the electric push rod 22 is provided with a mounting plate 24. The synchronizer 2 13 is connected between the mounting plate 24 and the support plate 41 so that the two can rotate synchronously. The driving member 14 is arranged on the frame 1, and is used to drive the rotating plate 11 to rotate relative to the frame 1. A telescopic rod is connected between each arc plate 21 and the mounting plate 24, and the length of the telescopic rod can be adapted with the movement of the arc plate 21.

[0040] Specifically, Figures 1 to 3 As shown, when the starting driving member 14 drives the rotating plate 11 to rotate, it can drive the electric push rod 22 to rotate, and at the same time, it can drive the support plate 41 to rotate synchronously through the synchronous member 12, and drive the mounting plate 24 to rotate synchronously through the synchronous member 2 13. Through the rotation of the electric push rod 22 and the mounting plate 24, the winding roller 2 can rotate around its own axis under the transmission of the connecting rod 23 and the telescopic rod to wind up the steel belt 5.

[0041] It should be noted that each set of clamping components also includes a support frame 33, which is fixedly connected to the frame body 1, and a support rod 34 is installed on the side of the support frame 33 facing the winding roller 2, and a U-shaped frame 35 is provided on the end of the support rod 34 away from the support frame 33, and the clamping roller 31 is rotatably arranged on the U-shaped frame 35. The support rod 34 is a telescopic structure, so that the length of the support rod 34 can be adapted according to the distance between the U-shaped frame 35 and the support frame 33, and the elastic member 32 is connected between the U-shaped frame 35 and the support frame 33.

[0042] In some embodiments, the second driving structure includes four sliding rods 43 and two fixed blocks 44. The four sliding rods 43 are distributed in a cross shape, and each sliding rod 43 slides with the support plate 41 along the radial direction of the winding roller 2. A push block 431 is provided at the end of each sliding rod 43 away from the winding roller 2. The two fixed blocks 44 are respectively sleeved on the outer sides of the support rods 34 in the two groups of clamping assemblies. The support plate 41 and the winding roller 2 are driven by the driving assembly to rotate, so that the steel strip 5 can be wound. As the steel strip 5 wound on the outer side of the winding roller 2 gradually increases, the clamping roller 31 will move in the direction away from the winding roller 2, and the fixed block 44 will move synchronously with the clamping roller 31 on the corresponding side. In addition, as the support plate 41 rotates, The push block 431 is driven to rotate synchronously with the sliding rod 43 that slides with the support plate 41, and drives the push block 431 to rotate. During this process, the push block 431 can contact with the fixed block 44, and as the fixed block 44 gradually moves away from the winding roller 2, the sliding rod 43 is pushed to slide in the direction away from the winding roller 2. The upper end of each sliding rod 43 is provided with a contact surface 1 433 and a contact surface 2 434. The height of the contact surface 1 433 is lower than that of the contact surface 2 434, and the contact surface 1 433 and the contact surface 2 434 are connected by an inclined surface 432. The inclined surface 432 is inclined upward in the direction close to the axis of the winding roller 2. A contact roller 421 is provided at the bottom of each support block 42, and the contact roller 421 is in contact with the upper end of the sliding rod 43.

[0043] Specifically, Figures 1 to 6As shown, in the initial state, the contact roller 421 at the lower end of each support block 42 contacts the contact surface 433 at the upper end of the corresponding sliding rod 43. At this time, the support block 42 is in the slide groove provided on the support plate 41. As the steel strip 5 wound up on the outer side of the winding roller 2 gradually increases, the sliding rod 43 will move in the direction away from the winding roller 2 under the cooperation of the fixed block 44 and the pushing block 431. In this process, the contact roller 421 will slide along the contact surface 433 until the contact roller 421 at the lower end of the innermost support block 42 contacts the inclined surface 432 at the upper end of the sliding rod 43. At this time, as the sliding rod 43 continues to move away from the winding roller 2, the contact roller 421 will move upward under the guidance of the inclined surface 432, and drive the support block 42 located at the innermost side to move upward, so that the support block 42 is in contact with the lower side of the wound steel strip 5. The steel strip 5 is supported by the support block 42, and the steel strip 5 is supported by the support block 42.

[0044] It should be noted that the outer sliding sleeve at the output end of the electric push rod 22 is provided with a mounting ring 25, and an elastic telescopic rod 45 is connected between each sliding rod 43 and the mounting ring 25 for driving the sliding rod 43 to reset, and the length of the elastic telescopic rod 45 can be adapted according to the distance between the sliding rod 43 and the mounting ring 25.

[0045] In some embodiments, the inclined surface 432 on each sliding rod 43 is located at a different position to ensure that different parts of each supporting block 42 can move up and down synchronously.

[0046] Specifically, Figures 1 to 6As shown, since the multiple support blocks 42 are distributed in a spiral shape and at intervals, the distance between any part on each support block 42 and the axis of the winding roller 2 is different, and the distance between the multiple contact rollers 421 at the lower end of the same support block 42 and the axis of the winding roller 2 is different. If the inclined surfaces 432 provided on each sliding rod 43 are in the same position, the multiple contact rollers 421 at the lower end of the same support block 42 cannot contact the inclined surfaces 432 on the corresponding sliding rods 43 at the same time, so that the multiple contact rollers 421 cannot move upward at the same time, that is, different parts of the support block 42 cannot move upward at the same time, and thus the support effect of the support block 42 on the steel strip 5 cannot be ensured. Therefore, in this embodiment, the inclined surfaces 432 on each sliding rod 43 are provided at different positions, which can ensure that the multiple contact rollers 421 at different positions at the lower end of the same support block 42 can contact the corresponding inclined surfaces 432 at the same time, so that different parts on the same support block 42 can move upward at the same time, so as to ensure the stable support of the steel strip 5 by the support block 42.

[0047] As the steel strip 5 wound up on the outside of the winding roller 2 gradually increases, the push block 431 and the fixed block 44 can cooperate to make the sliding rod 43 move away from the axis of the winding roller 2, and make the elastic telescopic rod 45 extend to store force. In this process, the inclined surface 432 and the contact roller 421 can cooperate to make the support block 42 move upward to support the part of the wound steel strip 5. At this time, if the sliding rod 43 moves toward the axis of the winding roller 2, the support block 42 will move upward under its own gravity and the guiding effect of the inclined surface 432. Therefore, in some embodiments, the sliding rod 43 is also provided with a ratchet structure for unidirectionally locking the sliding rod 43, and the ratchet structure includes four sets of matching ratchet bars 1 46 and ratchet bars 2 47. The outer fixed sleeve at the output end of the electric push rod 22 is provided with a mounting ring 26. The four ratchet bars 1 46 are distributed in a cross shape at the lower end of the sliding rod 43, and each ratchet bar 1 46 is connected to the mounting ring 26. The four ratchet bars 2 47 are correspondingly arranged at the lower ends of the four sliding rods 43.

[0048] Specifically, Figure 1 , Figures 3 to 6As shown, when the steel strip 5 is wound, the electric push rod 22 is started, so that the output end of the electric push rod 22 extends upward, which drives the mounting ring 26 sleeved on the outer side of the output end of the electric push rod 22 to move upward, and drives the four ratchet bars 1 46 connected to the mounting ring 26 to move upward, so that the ratchet bar 1 46 cooperates with the ratchet bar 2 47 at the lower end of the sliding rod 43. At this time, the sliding rod 43 can be unidirectionally locked, so that during the winding process of the steel strip 5, the sliding rod 43 can only move in the direction away from the axis of the winding roller 2, and cannot move in the opposite direction, so as to ensure The support block 42 provides stable support for the wound steel strip 5; when the wound steel strip 5 is removed, the electric push rod 22 is started, so that the output end of the electric push rod 22 contracts downward, which will drive the mounting ring 26 to move downward, and drive the four ratchet bars 1 46 to move downward, so that the ratchet bar 1 46 and the ratchet bar 2 47 are disengaged, that is, the one-way locking of the sliding rod 43 is released. At this time, the sliding rod 43 can be moved toward the direction close to the winding roller 2 under the action of the elastic telescopic rod 45 to reset, and at the same time, the support block 42 will move downward relative to the support plate 41 to reset.
