Description

Technical Field

[0001] The utility model relates to the technical field of foil cold rolling and calendering, in particular to a foil rewinding device. Background Art

[0002] With the continuous advancement of technology, high-end fields such as photovoltaic solar energy and 5G smartphones are rapidly developing, driving increasing demand for stainless steel foil. In the traditional stainless steel foil production process, semi-finished steel strip is typically rewound onto solid reels via a specialized rewinder, then transferred to a 20-high rolling mill for calendering. After rolling, the finished product is transferred to a specialized rewinder for rewinding onto reels for the next process. However, in recent years, the thickness of stainless steel foil required in high-end fields has become increasingly thinner, reaching only 10 to 30 μm. Such thin steel strips are prone to edge damage during transportation, impacting product quality. Furthermore, this traditional production method is inefficient and cannot meet the current market demand for high-end stainless steel foil. Therefore, there is an urgent need for new production technologies or equipment that can both prevent foil damage during transportation and improve production efficiency to meet the rapidly growing needs of high-end fields such as photovoltaic solar energy and 5G smartphones.

[0033] like Figure 1 As shown, this embodiment provides an online foil rewinding device, which includes a rolling mechanism 2 and a rewinding mechanism 3.

[0034] The rolling mechanism 2 includes a first frame 211, a first coiler 21, a rolling mill 23 and a second coiler 25. The first frame 211 supports the first coiler 21, the rolling mill 23 and the second coiler 25. The rolling mill 23 is located in the middle of the first frame 211 and is used to roll the foil 1 to improve the quality and performance of the foil 1 product. The first coiler 21 and the second coiler 25 are distributed on both sides of the rolling mill 23 and are used to coil the foil 1 during the rolling process.

[0035] Preferably, in order to guide the running direction of the foil 1 during the rolling process and ensure that the foil 1 passes through the rolling mill 23 smoothly for processing without causing wear, the rolling mechanism 2 also includes a first guide 22 and a second guide 24, both of which are arranged on the first frame 211, the first guide 22 is arranged between the first coiler 21 and the rolling mill 23, and the second guide 24 is arranged between the second coiler 25 and the rolling mill 23. When the rolling mill 23 is performing the rolling operation, no matter which end of the foil 1 moves to the first frame 211, the first guide 22 and the second guide 24 can support and guide the foil 1, thereby further ensuring production quality.

[0036] The rewinding mechanism 3 includes a second frame 311, a first unwinder 31, a tension measuring assembly 33 and a second unwinder 36. The second frame 311 serves as a supporting structure of the rewinding mechanism 3 and carries the tension measuring assembly 33. The tension measuring assembly 33 is arranged on the second frame 311. The first unwinder 31 and the second unwinder 36 are respectively located on both sides of the tension measuring assembly 33. The first unwinder 31 is located on the first frame 211 and on the side of the second coiler 25 away from the rolling mill 23. During the rewinding process, the first unwinder The machine 31 can be used to receive the rolled steel coil transferred from the rolling mechanism 2, and transfer the rolled steel coil to the second unwinder 36 through the rewinding mechanism 3 to wind the foil 1 into a finished coil. It can also be rolled up at the position of the second unwinder 36, and the steel coil is transferred to the first unwinder 31 in reverse through the rewinding mechanism 3 to prepare for extended rolling. This reduces the number of times the foil coil is lifted and transferred back and forth in the traditional production mode or avoids lifting the foil coil, greatly reduces the risk of damage to the edge of the foil coil, and improves production efficiency.

[0037] Preferably, the rewinding mechanism 3 also includes a third guide member 32 and a fourth guide member 34, and the third guide member 32 and the fourth guide member 34 are both arranged on the second frame 311, the third guide member 32 is arranged between the first rewinder 31 and the tension measuring assembly 33, and the fourth guide member 34 is arranged between the second rewinder 36 and the tension measuring assembly 33.

[0038] Preferably, the third guide member 32 and the fourth guide member 34 are equidistant from the tension measuring assembly 33, so that the foil 1 forms a wrap angle of approximately 60 degrees on the third guide member 32, the tension measuring assembly 33, and the fourth guide member 34, guiding the running direction of the foil 1 during the rewinding process while also ensuring the stability of the foil 1 during the rewinding process and the uniformity of the tension applied thereto.

[0039] Preferably, a limiting groove is provided on the first frame 211, and the second winder 25 and the first rewinder 31 are both located in the limiting groove.

[0040] Furthermore, a limit groove is arranged at one end of the first frame 211 close to the rewinding mechanism 3, the second coiler 25 is arranged at the end of the limit groove away from the rewinding mechanism 3, and the first unwinder 31 is arranged at the end of the limit groove close to the rewinding mechanism 3. The limit groove provides a connection position for the series connection of the rolling mechanism 2 and the rewinding mechanism 3, and can also provide storage space for the steel coils rewound from the rewinding mechanism 3 to the rolling mechanism 2 for rolling, so that the steel coils can be transferred to the rolling mechanism 2 without transshipment and lifting, and at the same time, it will not affect the normal production of the rolling mechanism 2.

[0041] according to Figure 2 It can be seen that the tension measuring assembly 33 includes a base 331, a support 332, a tension sensor 333 and a measuring roller 334, wherein the base 331 and the support 332 are rotatably connected, the tension sensor 333 is arranged between the base 331 and the support 332, and is used to measure the pressure applied to it by the support 332, and the measuring roller 334 is arranged on the upper surface of the support 332, and the axis direction of the rotational connection between the base 331 and the support 332 is parallel to the axis direction of the measuring roller 334. When measuring the tension, the tension borne by the foil 1 will be transmitted to the measuring roller 334, and then to the support 332. The support 332 drives the measuring roller 334 to rotate in a first direction along the axis direction of the rotational connection between the base 331 and the support 332 to apply pressure to the tension sensor 333, and the tension borne by the foil 1 is measured by the tension sensor 333.

[0042] like Figure 1 As shown, the foil online rewinding device also includes a tension control system 4, which is communicated with the tension sensor 333 and the second unwinder 36 respectively. The tension control system 4 is used to adjust the rotation speed of the second unwinder 36 according to the tension detected in real time by the tension sensor 333 to achieve constant tension rewinding. When the tension sensor 333 detects that the tension exceeds or is less than the preset value, the tension control system 4 automatically adjusts the rotation speed of the second unwinder 36 to maintain the tension at the preset value, ensuring that the foil 1 will not be stretched, wrinkled, or other undesirable phenomena during the rewinding process.

[0043] Preferably, in order to make the tension measured by the tension sensor 333 more accurate, the tension measuring assembly 33 also includes a fixing part 335, a groove is provided on the upper surface of the support 332, and the measuring roller 334 is provided in the groove on the upper surface of the support 332, and the dimension of the groove along the axial direction of the measuring roller 334 is larger than the dimension of the measuring roller 334 along the axial direction, so that the position of the measuring roller 334 on the upper surface of the support 332 can be adjusted along the axial direction of the rotating shaft 3312 along the groove, and the fixing part 335 is threadedly connected to one side wall of the groove in a direction perpendicular to the axial direction of the measuring roller 334, and the end of the fixing part 335 can make the measuring roller 334 abut against the other side wall of the groove in a direction perpendicular to the axial direction of the measuring roller 334. When the position of the measuring roller 334 needs to be adjusted, the fixing part 335 is first loosened to allow the measuring roller 334 to slide in the groove. After adjusting it to the appropriate position, the fixing part 335 is tightened.

[0044] Preferably, the rewinding mechanism 3 also includes a correction component 35, which includes a detection sensor, a control unit and an execution unit. The correction component 35 is a prior art, which uses a photoelectric sensor, an ultrasonic sensor or an inductive sensor to be installed at an appropriate position on the coil running path to monitor the edge position of the coil in real time. The electrical signal output by the sensor is transmitted to the control unit, which processes and analyzes the signal and determines whether the edge of the coil has deviated and the direction and degree of the deviated position by comparing it with the preset standard position. According to the detected deviated situation, the control unit uses a specific control algorithm to calculate the corrective action to be performed, and the execution unit calculates the corrective action to be performed according to the detected deviated situation. According to the instructions of the control unit, corresponding actions are performed to adjust the position of the coil. Common execution units include electric push rods, hydraulic cylinders or pneumatic cylinders. The execution unit can push or pull the guide device of the coil to make the edge of the coil return to the correct position; the correction component 35 is located between the fourth guide 34 and the second unwinder 36, and the foil 1 is passed through the detection sensor. The detection sensor and the control unit are communicated and connected, and the control unit is communicated and connected with the execution unit. When the correction component 35 detects that the edge of the foil 1 transferred from the previous process is not neat, the correction component 35 can automatically correct the deviation so that the foil 1 is neatly rewound onto the first unwinder 31 or the second unwinder 36 to avoid edge damage.

[0045] The steps for rewinding in preparation for rolling:

[0046] The foil 1 transferred from the previous process is first installed on the second unwinder 36. The edge of the foil 1 passes through the fourth guide 34, the tension measuring component 33 and the third guide 32 through the correction component 35, forming a wrap angle of about 60 degrees and then is wound onto the first unwinder 31.

[0047] Set the preset tension, start the equipment, and under the real-time monitoring of the correction component 35, the steel coil transferred from the previous process is neatly rewound onto the first unwinder 31 to prepare for calendering and rolling production. At this time, it does not affect the normal rolling operation of the rolling mill 23.

[0048] The steps for rewinding the rolled steel coil are as follows:

[0049] After rolling, the steel coil rolls from the second coiler 25 to the workstation of the first unwinder 31, passes through the third guide 32, the tension measuring assembly 33 and the fourth guide 34, and the foil 1 forms a wrap angle of approximately 60 degrees. The edge of the foil 1 passes through the correction assembly 35 and is wound on the second unwinder 36.

[0050] Set the preset tension and start the equipment. The tension of the foil 1 is detected in real time by the tension sensor 333. When the tension exceeds or is less than the preset value, the tension control system 4 automatically adjusts the speed of the second unwinder 36 to achieve constant tension rewinding. Under the control of the correction component 35, the edge of the foil 1 is neatly wound onto the second unwinder 36 without any damage to the edge.

[0051] Through rational structural design and advanced technological applications, this new online foil rewinding device enables the direct rewinding of rolled coils, as well as the neat online rewinding of coils transferred from previous processes. This overcomes the edge damage caused by the back-and-forth transport of foil in traditional production models while significantly improving production efficiency. This device boasts a compact structure, easy operation, strong deviation correction capabilities, and accurate tension control, meeting the stringent foil requirements of the high-end manufacturing industry and possessing broad application prospects.
