Description

Technical Field

[0001] This utility model relates to the field of industrial machinery and equipment technology, and in particular to a rewinding machine for flexible copper foil. Background Technology

[0002] The flexible copper foil rewinding machine is a key piece of equipment widely used in the copper foil production industry. Its main function is to rewind large rolls of copper foil into smaller rolls according to specific specifications and requirements. This includes feeding, guiding, cutting, winding, and waste removal of the roll material for subsequent processing and use.

[0003] A search revealed Chinese Patent Publication No. CN204223876U, which discloses a rewinding machine. The machine includes an unwinding device, a winding device, and a motor mounted on a frame. The unwinding device comprises an unwinding roller, an unwinding clamping cylinder, an unwinding swing arm, and an unwinding swing arm transmission component. The unwinding roller is located inside the two wall panels of the rewinding machine. The piston rod of the unwinding clamping cylinder is connected to the unwinding swing arm via the unwinding swing arm transmission component. The winding device comprises a winding roller, a winding swing arm cylinder, a winding swing arm shaft, a winding swing arm, and a winding swing arm transmission component. The piston rod of the winding swing arm cylinder is connected to both ends of the winding swing arm shaft via the winding swing arm transmission component. The motor is connected to the unwinding roller via a transmission belt, and the unwinding roller is connected to the winding roller via the transmission belt. This device ensures that the produced film rolls are of uniform size and have flat, burr-free end faces. It can also produce film rolls of various sizes and widths, resulting in stable product quality and improved product qualification rate. However, in actual use, the above-mentioned device has the following problems: the unwinding roller is cumbersome to operate when installing the roll material, and it is difficult to securely install the roll material according to different inner diameter sizes, which leads to slippage during the unwinding process. Therefore, a rewinding machine is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rewinding machine for flexible copper foil, which aims to improve the problem in the prior art that the unwinding roller is difficult to securely install according to the different inner diameters of the roll.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding machine for flexible copper foil, comprising a control box, a support frame, and a base plate. A servo motor is fixedly connected to the rear side of the control box. The output end of the servo motor passes through the rear side of the control box and is fixedly connected to a connecting end. An unwinding roller is fixedly connected to the front end of the connecting end. Extrusion plates are slidably connected to the inner circumference of the unwinding roller. Limiting plates are fixedly connected to adjacent sides of multiple extrusion plates. Springs are fixedly connected to the opposite sides of multiple limiting plates. A bolt is threadedly connected to the front end of the unwinding roller. The rear end of the bolt passes through the front side of the unwinding roller and is rotatably connected to an extrusion tooth plate. A rotating seat is fixedly connected to the front side of the support frame. A mounting seat is rotatably connected to the inner side of the rotating seat. A first insertion hole is opened on the top of the mounting seat. A second insertion hole is opened on the top of the rotating seat. A screw is installed inside the second insertion hole. The bottom end of the screw passes through the inner side of the first insertion hole and is threadedly connected to a nut. A winding mechanism is provided on the front side of the control box.

[0006] The above technical solution involves tightly mounting the unwinding roller and servo motor onto the control box, rotating the nut and removing the screw to rotate the mounting base, thus opening the unwinding roller and placing the copper foil roll. To ensure the stability of the copper foil roll, the front side of the extrusion tooth plate is slid by rotating the bolt, allowing the extrusion tooth plate to press against the surrounding extrusion plates, thereby unfolding the roll outwards and firmly clamping the inner wall of the copper foil roll. This ensures the stability of the copper foil roll during unwinding.

[0007] As a further description of the above technical solution:

[0008] The winding mechanism includes two mounting frames, which are fixedly connected to the left side of the control box and the support frame, respectively. A receiving plate is fixedly connected between adjacent mounting frames. Sliding rods are slidably connected to the four corners of the bottom of the receiving plate. A connecting plate is fixedly connected to the bottom of the sliding rods. A cylinder is fixedly connected to the bottom of the connecting plate. One end of the cylinder passes through the bottom of the connecting plate and is fixedly connected to the bottom of the receiving plate. Pressure strips are fixedly connected to the top of the sliding rods. Suction plates are fixedly connected to the bottom of the two pressure strips. An air pump is fixedly connected to the front of the front mounting frame. One end of the air pump is connected to a vacuum tube. One end of the vacuum tube passes through the top of the pressure strip and is connected to the top of the suction plate.

[0009] The above technical solution involves starting an air pump to work with suction plates to adsorb the copper foil at the tail end when the copper foil at the other end is rolled back. Since the copper foil joint uses an adhesive tape joint, when the two are pressed together, the cylinder is activated to press the pressure plate to squeeze the copper foil, thus completing the rapid jointing process.

[0010] As a further description of the above technical solution:

[0011] The winding mechanism also includes two conveying rollers, which are rotatably connected between adjacent parts of the mounting frame.

[0012] The above technical solution involves installing conveyor rollers on both sides of the receiving plate, which effectively ensures the tension between them and provides the conveying endpoint.

[0013] As a further description of the above technical solution:

[0014] Tension adjusting rollers are installed between adjacent parts of the control box and the support frame, and roller columns are rotatably connected between adjacent parts of the control box and the support frame.

[0015] The above technical solution involves installing a pressure sensor on the tension regulating roller, which can accurately detect the tension of the copper foil during the conveying process and make timely adjustments.

[0016] As a further description of the above technical solution:

[0017] An adjustment device is fixedly connected to the left side of the control box, and an adjustment seat is threadedly connected to the inner side of the adjustment device.

[0018] The above technical solution involves an internal threaded rod for the adjusting device, with an adjusting seat mounted on the threaded rod. By activating the adjusting device, the adjusting seat can slide left and right.

[0019] As a further description of the above technical solution:

[0020] A drive device is fixedly connected to the left side of the adjustment device, and a take-up roller is rotatably connected between the drive device and the adjacent adjustment seat.

[0021] The above technical solution involves installing a take-up roller between the adjusting seat and the driving device. The driving device can drive the take-up roller to rotate, thereby achieving the take-up processing of copper foil.

[0022] As a further description of the above technical solution:

[0023] Support columns are fixedly connected to the four corners of the bottom of the base plate, and rubber seats are fixedly connected to the bottom ends of the multiple support columns. Reinforcing plates are fixedly connected to the outer walls of the support columns.

[0024] The above technical solution involves supporting and fixing the entire device with multiple support columns, and using rubber seats to improve stability.

[0025] As a further description of the above technical solution:

[0026] A controller is fixedly connected to the left side of the control box. The controller is electrically connected to the cylinder, air pump, servo motor, adjustment device and drive device respectively.

[0027] The above technical solution allows for convenient and simple operation and control of the operating equipment throughout the entire device via a controller.

The unwinding roller 12 and the connecting end 5 are integrally formed to improve the overall support strength. Extrusion plates 13 are slidably connected to the inner circumference of the unwinding roller 12. Limiting plates 14 are fixedly connected to adjacent sides of the multiple extrusion plates 13. Multiple limiting plates 14 are fixedly connected to springs 15 on opposite sides. Extrusion plates 13 are slidably mounted around the inner perimeter of the unwinding roller 12.

The extrusion plates 13 are in contact with each other and with the grooves on the extrusion toothed plate 16. When the rotating bolt 17 drives the extrusion toothed plate 16 to slide forward, the grooves press against each other, thus compressing the extrusion plates 13 and causing them to unfold outwards. This quickly achieves the effect of rapidly adhering to the inner wall of the copper foil roll, completing the fitting and installation. A rotating seat 6 is fixedly connected to the front side of the support frame 3. A mounting seat 7 is rotatably connected to the inner side of the rotating seat 6.

The extrusion plates 13 are in contact with each other and the grooves on the extrusion tooth plate 16. When the rotating bolt 17 drives the extrusion tooth plate 16 to slide forward, the grooves are squeezed against each other, thereby extruding the extrusion plate 13 in all directions.
