Description

Technical Field

[0001] This utility model relates to the field of unwinding equipment technology, and in particular to a multifunctional unwinding device. Background Technology

[0002] In the manufacturing process of copper-clad laminates, copper sheets are typically wound in rolls onto spools for easy transport and subsequent processing. For example... Figure 1 The shown roll 101 consists of two parts: a hollow core 102 for winding the copper plate roll 100, and a base 103 fitted outside the hollow core 102 to support the bottom of the copper plate roll 100 and ensure the stability of the roll. For subsequent processes to proceed smoothly, the copper plate roll 100 needs to be unwound. There are two unwound methods: internal unwound and external unwound. Internal unwound unwound unwinds the copper foil by applying force from inside the core, while external unwound unwinds by using an external device to rotate the core. These two unwound methods typically require separate devices, resulting in complex structures and cumbersome operations. Utility Model Content

To this end, this invention proposes a multifunctional unwinding device that integrates an outer unwinding component and an inner unwinding component into one unit, realizing a multifunctional operation that allows for switching between inner and outer unwinding.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multifunctional unwinding device, comprising:

[0006] The external unwinding assembly includes a first rotating shaft structure for placing the entire roll and a first driving structure for driving the first rotating shaft structure to rotate.

[0007] The inner loose winding assembly includes an expansion fixing assembly for driving the hollow winding core to rotate and a clamping mechanism for fixing the base; the expansion fixing assembly includes a second rotating shaft structure that can be inserted into the inner hole of the hollow winding core, at least two top plates circumferentially distributed on the outside of the second rotating shaft structure, and a second driving structure for driving the second rotating shaft structure to rotate, wherein the second rotating shaft structure can cause the top plates to expand radially outward, thereby clamping the inner wall of the hollow winding core.

[0008] According to some embodiments of the present invention, the second rotating shaft structure includes a vertically arranged first rotating shaft seat, an inflatable airbag structure disposed within the first rotating shaft seat, and a top block structure disposed outside the airbag structure that can pass through the first rotating shaft seat and connect to the top plate.

[0009] According to some embodiments of the present invention, the top block structure includes a plurality of arc-shaped plates disposed on the outer side of the airbag structure, a plurality of first sliding blocks disposed on the outer sidewall of the arc-shaped plates, and a second sliding block disposed on the inner sidewall of the top plate and slidably connected to the first sliding blocks. The first rotating shaft seat has a transverse through groove that cooperates with the second sliding block.

[0010] According to some embodiments of the present invention, the first sliding block has a vertically arranged T-shaped groove, and the second sliding block has a T-shaped protrusion that slides in conjunction with the T-shaped groove.

[0011] According to some embodiments of the present invention, the second rotating shaft structure further includes a return spring disposed between the inner sidewall of the first rotating shaft seat and the arc-shaped plate.

[0012] According to some embodiments of the present invention, the clamping mechanism includes a plurality of first clamping blocks disposed on the periphery of the base and conforming to the shape of the base, and a third driving structure for driving the first clamping blocks to clamp laterally toward the base.

[0013] According to some embodiments of the present invention, the second rotating shaft structure further includes a base rotating seat disposed outside the first rotating shaft seat and a rotating base disposed below the first rotating shaft seat and the base rotating seat.

[0017] This utility model has at least the following beneficial effects:

[0018] This multi-functional unwinding device integrates an outer unwinding assembly and an inner unwinding assembly, enabling flexible switching between inner and outer unwinding. The outer unwinding assembly uses a first rotating shaft structure to drive the entire roll to rotate; the inner unwinding assembly clamps the roll core from the inside through an expansion fixing assembly and drives the roll core to rotate.

[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0027] An embodiment of this utility model provides a multifunctional unwinding device, such as... Figure 1-5 As shown, it includes:

[0028] The external unwinding assembly 201 includes a first rotating shaft structure 202 for placing the entire roll 101 and a first driving structure 203 for driving the first rotating shaft structure 202 to rotate.

[0029] The inner loosening assembly 301 includes an expansion fixing assembly 302 for driving the hollow core 102 to rotate and a clamping mechanism 303 for fixing the base 103. The expansion fixing assembly 302 includes a second rotating shaft structure 307 that can be inserted into the inner hole of the hollow core 102, at least two top plates 304 circumferentially distributed outside the second rotating shaft structure 307, and a second driving structure 305 for driving the second rotating shaft structure 307 to rotate. The second rotating shaft structure 307 can cause the top plates 304 to expand radially outward, thereby clamping the inner wall of the hollow core 102.

[0030] The multi-functional unwinding device combines an outer unwinding assembly 201 and an inner unwinding assembly 301, enabling it to adapt to the unwinding operations of various copper-clad laminate (CCL) rolls 101. The CCL roll 101 is inserted into and placed on the first rotating shaft structure 202 of the outer unwinding assembly 201. The first rotating shaft structure 202 has a vertically arranged columnar structure that can be inserted into the inner hole of the hollow core 102 of the roll 101. The first driving structure 203, including a drive motor, cylinder, and hydraulic motor, can drive the first rotating shaft structure 202 to rotate as a whole, thereby driving the roll 101 to rotate as a whole, facilitating the outer unwinding operation of the CCL.

[0031] The inner loosening assembly 301 clamps and drives the core 102 to rotate from inside, while the clamping mechanism 303 clamps the base 103 to prevent the external copper plate from rotating, thus achieving the inner loosening operation. The hollow core 102 of the copper-clad laminate roll 101 is fixed by the expansion fixing assembly 302. Specifically, a vertically arranged second rotating shaft structure 307 can be inserted into the inner hole of the hollow core 102. The second rotating shaft structure 307 expands its outer top plate 304 radially outward through methods such as slider ejection and expansion ejection, so that the top plate 304 abuts against and presses against the inner sidewall of the hollow core 102, thereby fixing the hollow core 102. The second driving structure 305, such as a drive motor, cylinder, or hydraulic motor, drives the second rotating shaft structure 307 to rotate, thereby driving the connected top plate 304 and the hollow core 102 to rotate. The end of the roll material 100, which is fixed to the hollow core 102, also rotates accordingly, achieving the inner loosening effect. The clamping mechanism 303 clamps the hollow core base 103 from the outside inwards. It can also be a clamping structure such as a fastening clamp on the upper side of the base 103, ensuring that the base 103 remains fixed during unwinding and does not rotate with the hollow core 102, thus improving the accuracy and reliability of the inner unwinding. This device integrates the outer unwinding component 201 and the inner unwinding component 301. When the clamping mechanism 303 is not clamping the base 103, the inner unwinding component 301 can still rotate synchronously with the outer unwinding component 201, achieving a multi-functional switchable operation between inner and outer unwinding. The outer unwinding component 201 can have the same structure as the inner unwinding component 301, facilitating easy switching between inner and outer unwinding functions.

[0032] In some embodiments, such as Figure 2-5 As shown, the second rotating shaft structure 307 includes a vertically arranged first rotating shaft seat 308, an inflatable airbag structure 309 disposed within the first rotating shaft seat 308, and a top block structure 310 disposed outside the airbag structure 309 that can pass through the first rotating shaft seat 308 and connect to the top plate 304.

[0033] The airbag structure 309 inside the first rotating shaft seat 308 is inflated by an air pump or other structures, achieving lateral expansion. This causes the top block structure 310, located on the outer wall of the airbag structure 309, to also push outward laterally, thereby driving the top plate 304 to expand radially outward. The operation is simple and easy to control, enabling rapid clamping of the inner wall of the core. The second drive structure 305 can simultaneously drive the first rotating shaft seat 308, the airbag structure 309, and other structures, achieving rotation of the entire second rotating shaft structure 307.

[0034] Furthermore, such as Figure 3-5As shown, the top block structure 310 includes a plurality of arc-shaped plates 311 disposed on the outer side of the airbag structure 309, a plurality of first sliding blocks 312 disposed on the outer side wall of the arc-shaped plates 311, and a second sliding block 313 disposed on the inner side wall of the top plate 304 and slidably connected to the first sliding blocks 312. The first rotating shaft seat 308 has a transverse through groove 314 that cooperates with the second sliding block 313.

[0035] The arc-shaped plate 311 expands uniformly outward as the airbag structure 309 inflates, protecting the airbag structure 309 while facilitating the pushing of the top plate 304. Multiple first sliding blocks 312 are provided on the outer wall of the arc-shaped plate 311, while second sliding blocks 313, slidably connected to the first sliding blocks 312, are provided on the inner wall of the top plate 304. This sliding connection reduces instability in the pushing direction when the airbag structure 309 inflates, reduces vertical vibration interference, and enables the lateral pushing of the top plate 304. The first sliding blocks 312 and second sliding blocks 313 can be connected in various ways, such as a sliding block and a horizontal push block, or a vertical guide groove and a vertical guide block.

[0036] Furthermore, such as Figure 3 , 5 As shown, the first sliding block 312 has a vertically arranged T-shaped groove 315, and the second sliding block 313 has a T-shaped protrusion 316 that slides in conjunction with the T-shaped groove 315.

[0037] The vertically arranged T-shaped sliding structure is easy to process, while ensuring the stability and accuracy of the top plate 304 during radial movement. It further reduces the vertical jitter interference when the second sliding block 313 is pushed, effectively preventing the slider from shifting or jamming during movement, thereby improving the reliability and durability of the entire unwinding device.

[0038] Furthermore, such as Figure 3-5 As shown, the second rotating shaft structure 307 also includes a return spring 317 disposed between the inner side wall of the first rotating shaft seat 308 and the arc plate 311.

[0039] The reset spring 317 can automatically retract and reset the top plate 304 after the airbag is deflated, simplifying the operation process and improving work efficiency.

[0040] Furthermore, such as Figure 4 As shown, the clamping mechanism 303 includes a plurality of first clamping blocks 319 arranged around the base 103 and conforming to the shape of the base 103, and a third driving structure 324 for driving the first clamping blocks 319 to clamp laterally toward the base 103.

[0041] The first clamping block 319 is specifically an arc-shaped clamping block symmetrically arranged on the outer side of the base 103, matching the shape of the outer edge of the base 103. It can apply clamping force evenly, achieving precise clamping of the base 103 and ensuring stable fixation of the base 103 during unwinding. The spacing between the inner wall of the base 103 and the outer wall of the rapidly rotating hollow core 102 prevents damage due to rotational friction and also prevents the clamping force from being transmitted to the core, further improving the reliability and stability of the unwinding operation.

[0042] Furthermore, such as Figure 4 As shown, the second rotating shaft structure 307 also includes a base rotating seat 318 disposed outside the first rotating shaft seat 308 and a rotating base 325 disposed below the first rotating shaft seat 308 and the base rotating seat 318. Both the first rotating shaft seat 308 and the base rotating seat 318 can rotate on the rotating base 325, and the base 103 is placed on the base rotating seat 318.

[0043] The rotating chassis 325 provides a platform for the rotation of the first rotating shaft seat 308 and the base rotating seat 318, improving their support force and stability during rotation, and extending the lifespan of the second rotating shaft structure 307. The base rotating seat 318 is used to hold the base 103. When the clamping mechanism 303 clamps the base 103, the second rotating shaft structure 307 rotates while the base rotating seat 318 remains stationary, achieving an internal unwinding function. When the clamping mechanism 303 does not clamp the base 103, the base 103 can rotate with the hollow core 102, causing the base rotating seat 318 to rotate synchronously with the first rotating shaft seat 308, achieving the effect of overall rotation of the drum 101. This allows the internal unwinding assembly to be switched to an external unwinding mode when necessary, greatly improving the flexibility and versatility of the equipment. Furthermore, the base rotating seat 318 may also have a groove adapted to the base 103.

[0044] Furthermore, such as Figure 4 As shown, the clamping mechanism 303 also includes a fixing structure 320 disposed on one side of the base 103 for fixing the outermost loosely coiled material.

[0045] During the inner unwinding process, the outermost copper plate needs to be loosened to a suitable position and fixed before the inner unwinding can begin. Currently, this is done by sticking it with tape. However, the adhesive of the tape will gradually lose its stickiness after being torn and pasted multiple times, making it easy to loosen and cause material deformation. The fixing structure 320 can fix the copper plate at the outer end, preventing it from loosening or shifting during the unwinding process and improving the unwinding quality.

[0046] Furthermore, such as Figure 4As shown, the fixing structure 320 includes a circular track 321 surrounding the base 103, a sliding rod 322 slidably disposed on the circular track 321, and a second clamping block 323 disposed on the sliding rod 322 for fixing the copper plate.

[0047] The circular track 321 allows the sliding rod 322 to slide flexibly and adjust around the base 103, enabling the second clamping block 323 to quickly position and clamp the outer end of the coil material with different tightness. This facilitates unwinding while preventing loosening, ensuring the copper plate remains stable during unwinding and avoiding shaking or displacement, thus significantly improving the accuracy and reliability of the unwinding operation. Furthermore, a fixing block for fixing the sliding rod 322 can be provided on the circular track 321 or the base 103.

[0048] In some embodiments, such as Figure 2 As shown, the first rotating shaft structure 202 includes a vertically arranged rotating shaft 204 and a synchronous rotating seat 206 disposed below the rotating shaft 204. The synchronous rotating seat 206 is provided with a groove 205 for placing the hollow core 102 and the base 103.

[0049] The groove 205 provides stable support and positioning for the hollow core 102 and the base 103, ensuring that the drum can rotate synchronously during unwinding and preventing the drum from shifting or shaking during rotation.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
