Description

Technical Field

[0001] This invention belongs to the field of foil making machine technology, and particularly relates to a foil making machine that facilitates the winding of electrolytic copper foil. Background Technology

[0002] The copper foil forming machine is a core piece of equipment in the electrolytic copper foil production process. Its main function is to generate copper foil on the surface of the cathode roller through electrolysis, and after a series of subsequent processing steps (such as cleaning or drying), the copper foil is wound up to form copper foil rolls that can be used by downstream industries. In modern electronics, information technology, and new energy fields, electrolytic copper foil is a key basic material, and its quality and production efficiency directly depend on the technical performance of the copper foil forming machine.

[0003] Existing copper foil production machines typically consist of an electrolysis system, a cleaning and drying system, and a winding system. Among these, the winding system, as a crucial step after copper foil formation, primarily functions to neatly and tightly wind the cleaned and dried copper foil onto a core for subsequent storage, transportation, and processing. Existing copper foil production machines typically rely on manual methods such as using tape to secure the initial section of the winding process or employ complex mechanical pressing devices.

[0004] However, manual pasting is not only labor-intensive and increases labor costs, but also relies entirely on experience to control the pasting force and position. This can easily lead to problems such as loosening or wrinkling of the initial section of the copper foil due to insufficient pasting, or local stretching and deformation of the copper foil due to excessive pasting, which seriously affects the stability of the winding quality. Mechanical pressing devices often cannot flexibly adjust the pressing force, and after the initial section is fixed, the retraction process is cumbersome and slow, which can easily interfere with the already wound copper foil, causing scratches on the copper foil surface. At the same time, it will also prolong the roll change time and reduce production efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a foil-making machine that makes electrolytic copper foil easy to rewind, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a foil-making machine that facilitates the winding of electrolytic copper foil, so as to solve the problems in the background technology mentioned above.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A copper foil production machine for easy winding of electrolytic copper foil includes an electrolysis system, a cleaning and drying system, and a winding system. The cleaning and drying system and the winding system are all installed on the same frame, and the cleaning and drying system is located between the electrolysis system and the winding system.

[0009] The winding system includes a pressure roller assembly, a winding roller, an outer bearing, a core, a pressing mechanism, a centering clamping mechanism, an electrical control mechanism, and an installation limiting mechanism. The pressure roller assembly is rotatably mounted on the frame and located on one side of the winding roller. The electrical control mechanism and the installation limiting mechanism are symmetrically mounted on the left and right sides of the frame. Outer bearings are fixed on the outer walls at both ends of the winding roller. The installation limiting mechanism fixes the winding roller through the outer bearings. A centering clamping mechanism is installed on the inner wall of the winding roller. One end of the centering clamping mechanism passes through a slotted hole on the winding roller and contacts the inner wall of the core. The other end of the centering clamping mechanism extends to the outside of one end of the winding roller and is connected to an electrical control mechanism. The other end of the winding roller is connected to another electrical control mechanism.

[0010] The pressing mechanism includes an annular sliding sleeve, a locking screw, a mounting block, a slider, a sealing plate, a spring, a pressure needle, and a Z-shaped lever. The annular sliding sleeve is symmetrically and slidably mounted on the outer walls of the left and right sides of the take-up roller. A locking screw that abuts against the outer wall of the take-up roller is threaded onto the annular sliding sleeve. A mounting block is radially fixed on one side of the annular sliding sleeve. A slider is radially slidably mounted inside the mounting block. A sealing plate is fixed on the top of the mounting block. A spring is installed between the top of the slider and the bottom of the sealing plate. A pressure needle and a Z-shaped lever are fixed on the left and right sides of the slider, respectively. The pressure needle is located outside the core.

[0011] As a further technical solution of the present invention, the inner diameter of the annular sliding sleeve is larger than the outer diameter of the take-up roller, and the pressure needle adopts a rod-shaped structure made of a metal material.

[0012] As a further technical solution of the present invention, the take-up roller is composed of two semi-circular rotating bodies connected together by bolts, and a centering clamping mechanism is installed between the two semi-circular rotating bodies.

[0013] As a further technical solution of the present invention, the centering and clamping mechanism includes a centering shaft, an inner bearing, a rotating seat, an eccentric guide groove, a fixed seat, a radial guide groove, a sliding column, and a clamping block. The centering shaft is disposed between two semi-circular rotating bodies, and the outer walls of both ends of the centering shaft are connected to the inner walls of both ends of the take-up roller through the inner bearing. One end of the centering shaft extends to the outside of the take-up roller and is connected to an electrical control mechanism. The rotating seats are equidistantly distributed on the outer wall of the centering shaft along the axial direction of the centering shaft. The fixed seat is fixed on the inner wall of one of the semi-circular rotating bodies and is disposed parallel to one side of the rotating seat. The rotating seat has eccentric guide grooves that slide in cooperation with the outer wall of the sliding column in a circumferential direction. The fixed seat has radial guide grooves that slide in cooperation with the outer wall of the sliding column in a circumferential direction. A clamping block is fixed at one end of the sliding column, and the clamping block corresponds to the strip hole opened on the take-up roller.

[0014] As a further technical solution of the present invention, the electrical control mechanism includes a motor frame, a control motor, a flange, an axial sleeve, and a fixed cylinder. The motor frame is symmetrically fixed on the left and right sides of the frame. The control motor is fixed on the motor frame. The flange is installed on the output end of the control motor. The fixed cylinder is fixed to the outer wall of the take-up roller and the centering shaft respectively by pins. An axial sleeve is horizontally slidably installed on one side of the fixed cylinder. The axial sleeve is fixedly connected to the flange by locking bolts. The flange is concentric with the axial sleeve, the fixed cylinder, the centering shaft, and the take-up roller respectively.

[0015] As a further technical solution of the present invention, the installation limiting mechanism includes a bearing seat, a pressure plate, an elastic pad, a stud, a throttle, and a locking plate. The bearing seat is symmetrically fixed on the left and right sides of the frame. A pressure plate is rotatably installed on one end of the bearing seat. The pressure plate is located on the top of the bearing seat. A connection port is opened on one end of the pressure plate. An elastic pad that contacts the outer bearing is installed on the inner wall of the pressure plate. A stud is rotatably installed on the other end of the bearing seat. A throttle is threaded on the stud. The stud cooperates with the connection port. A locking plate that intermittently contacts the pressure plate is fixed on the other end of the throttle.

[0016] As a further technical solution of the present invention, the pressure roller assembly includes a rotating frame, a pressure roller body, a pressure roller sleeve, and a hydraulic press. The rotating frame and the hydraulic press are symmetrically and rotatably installed on the left and right sides of the frame. The output end of the hydraulic press is connected to the middle of the rotating frame. The pressure roller body is installed between the two rotating frames, and the pressure roller sleeve is fixed in the middle of the pressure roller body.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The installation limiting mechanism can quickly fix the take-up roller, so that the core can stably wind up the copper foil. Two electrical control mechanisms are connected to the centering clamping mechanism and the take-up roller respectively. One electrical control mechanism works with the centering clamping mechanism to complete the centering clamping and fixing of the core, which improves the accuracy and efficiency of core installation, ensures that the core is always in the center position during the winding process, and makes the wound copper foil more uniform and neat, effectively improving product quality. At the same time, it reduces manual operation, reduces labor intensity, and improves the degree of production automation.

[0019] After the starting section of the copper foil is attached to the outer wall of the core, the Z-shaped lever is released. The spring drives the slider to move back quickly through its own elastic force. The slider drives the pressure needle to move back quickly and press the starting section of the copper foil onto the outer wall of the core. This ensures that the copper foil remains tightly attached during the winding process, avoiding loosening or wrinkles, and improving the winding efficiency and quality of the foil making machine.

[0020] During winding, two electrical control mechanisms work synchronously and in the same direction. Another electrical control mechanism drives the winding roller to rotate, which in turn drives the core, pressing mechanism, and centering clamping mechanism to rotate synchronously. The centering clamping mechanism and the electrical control mechanism connected to it, by rotating synchronously and in the same direction with the winding roller, ensure that the core remains stable during the winding of the copper foil. The core, in conjunction with the pressure needle, can quickly wind the copper foil, resulting in a tight winding and reducing gaps inside the copper foil roll. This allows for a larger length of copper foil to be accommodated in the same volume of packaging, reducing storage and transportation costs and preventing damage caused by loose copper foil during transportation. After winding is completed, the small cross-sectional diameter of the pressure needle allows it to quickly retract from the inside of the copper foil to the outside, facilitating the rapid winding of the next core and further improving the winding efficiency of the foil production machine.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figures 1 to 11As shown, an embodiment of the present invention provides a copper foil production machine for easy winding of electrolytic copper foil, comprising an electrolysis system 100, a cleaning and drying system 200, and a winding system 300. The cleaning and drying system 200 and the winding system 300 are both mounted on the same frame, with the cleaning and drying system 200 located between the electrolysis system 100 and the winding system 300. The electrolysis system 100 is equipped with a circulating pump, a filtration system, a temperature control system, a replenishment system, a liquid level control system, and a cathode and anode devices. Its core function is to continuously deposit copper ions from the electrolyte onto the cathode through electrode reactions under the influence of an electric field, achieving the reduction process from copper ions to copper foil. This is the key initial step in copper foil production. The cleaning and drying system 200 is equipped with a peeling system, a spraying system, and a drying system, mainly used to peel off the copper foil and clean and dry the peeled copper foil.

[0037] The winding system 300 includes a pressure roller assembly 310, a winding roller 320, an outer bearing 330, a core 400, a pressing mechanism 500, a centering clamping mechanism 600, an electrical control mechanism 700, and an installation limiting mechanism 800. The pressure roller assembly 310 is rotatably mounted on the frame and located on one side of the winding roller 320. The electrical control mechanism 700 and the installation limiting mechanism 800 are symmetrically mounted on the left and right sides of the frame. Outer bearings 330 are fixed to the outer walls at both ends of the winding roller 320. The mounting limiting mechanism 800 fixes the take-up roller 320 via the outer bearing 330. A centering clamping mechanism 600 is installed on the inner wall of the take-up roller 320. One end of the centering clamping mechanism 600 passes through the strip hole 321 opened on the take-up roller 320 and contacts the inner wall of the core 400. The other end of the centering clamping mechanism 600 extends to the outside of one end of the take-up roller 320 and is connected to an electrical control mechanism 700. The other end of the take-up roller 320 is connected to another electrical control mechanism 700.

[0038] The pressing mechanism 500 includes an annular sleeve 510, a locking screw 520, a mounting block 530, a slider 540, a sealing plate 550, a spring 560, a pressure needle 570, and a Z-shaped lever 580. The annular sleeve 510 is symmetrically and slidably mounted on the outer walls of the left and right sides of the take-up roller 320. The annular sleeve 510 is threaded with a locking screw 520 that abuts against the outer wall of the take-up roller 320. The mounting block 530 is radially fixed on one side of the annular sleeve 510. The slider 540 is radially slidably mounted inside the mounting block 530. The sealing plate 550 is fixed on the top of the mounting block 530. A spring 560 is installed between the top of the slider 540 and the bottom of the sealing plate 550. The pressure needle 570 and the Z-shaped lever 580 are fixed on the left and right sides of the slider 540, respectively. The pressure needle 570 is located outside the core 400.

[0039] In the initial state, the take-up roller 320 is detached from the outside of the mounting and limiting mechanism 800, and one end of the centering and clamping mechanism 600 is hidden inside the take-up roller 320, so that the outer wall of the take-up roller 320 is in a smooth state, which makes it easy to fit the core 400 and the pressing mechanism 500 on the outside of the take-up roller 320.

[0040] During installation, the outer bearings 330 at both ends of the take-up roller 320 are respectively installed in the installation limiting mechanisms 800 set on the left and right sides of the frame. The two electrical control mechanisms 700 are respectively connected to the centering clamping mechanism 600 and the take-up roller 320. The axial position of the core 400 on the take-up roller 320 is adjusted. One electrical control mechanism 700 cooperates with the centering clamping mechanism 600 to complete the centering clamping and fixing of the core 400, which improves the accuracy and efficiency of the core 400 installation, ensures that the core 400 is always in the center position during the winding process, makes the wound copper foil more uniform and neat, effectively improves product quality, and at the same time reduces manual operation, reduces labor intensity, and improves the degree of production automation.

[0041] Adjust the annular sliding sleeves 510 distributed on both sides of the core 400 to ensure that the pressure needles 570 on both sides are fully and effectively located outside the core 400, and fix the annular sliding sleeves 510 to the outer wall of the take-up roller 320 with locking screws 520; before winding the copper foil, push and pull the slider 540 with the Z-shaped lever 580, so that the slider 540 drives the pressure needles 570 to separate from the outer wall of the core 400, which can facilitate the removal of the copper foil on the pressure roller assembly 310. Pulled to the outer wall of the core 400, after the starting section of the copper foil is attached to the outer wall of the core 400, the Z-shaped lever 580 is released. The spring 560 drives the slider 540 to move back quickly through its own elastic force. The slider 540 drives the pressure needle 570 to move back quickly and press the starting section of the copper foil onto the outer wall of the core 400, ensuring that the copper foil remains tightly attached during the winding process, avoiding loosening or wrinkles, and improving the winding efficiency and winding quality of the foil making machine.

[0042] During winding, two electronic control mechanisms 700 operate synchronously and in the same direction. Another electronic control mechanism 700 drives the winding roller 320 to rotate. The winding roller 320 drives the core 400, the pressing mechanism 500, and the centering clamping mechanism 600 to rotate synchronously. The centering clamping mechanism 600 and its connected electronic control mechanism 700, by rotating synchronously and in the same direction as the winding roller 320, ensure that the core 400 remains stable throughout the winding process of the copper foil. The core 400 cooperates with the pressure needle 570. This allows for rapid winding of copper foil, resulting in a tighter coil and reducing internal gaps. This allows for the storage of more copper foil in a package of the same volume, lowering storage and transportation costs. It also prevents damage caused by loose copper foil during transport. After winding, the small cross-sectional diameter of the pressure pin 570 allows it to quickly retract from the inside of the copper foil to the outside, facilitating the rapid winding of the next core of 400 copper foil, further improving the winding efficiency of the foil production machine.

[0043] In a preferred embodiment, the pressure needle 570 is preferably a rod-shaped structure made of metal material, and the outer surface of the pressure needle 570 is smooth, which can reduce the resistance to its removal from the copper foil and facilitate the replacement of the next core 400 of the foil production machine for new copper foil winding.

[0044] Depending on the thickness and material properties of the copper foil, the clamping force of the pressure needle 570 can be adjusted by replacing the spring 560 with a different elastic coefficient, ensuring that the copper foil is firmly fixed without being damaged due to excessive pressure, thus improving the adaptability of the foil production machine to different types of copper foil.

[0045] like Figures 4 to 8 As shown, in a preferred embodiment of the present invention, the inner diameter of the annular sliding sleeve 510 is slightly larger than the outer diameter of the take-up roller 320. This not only ensures that the annular sliding sleeve 510 can slide to any position on the outer wall of the take-up roller 320, facilitating the engagement of the pressure needle 570 with cores 400 of different lengths, but also allows the locking screw 520 to quickly lock the annular sliding sleeve 510 onto the outer wall of the take-up roller 320, and greatly reduces the concentricity difference between the annular sliding sleeve 510 and the take-up roller 320, ensuring that the pressure needle 570 can effectively and fully press the copper foil onto the outer wall of the core 400, thereby improving the winding efficiency and quality of the core 400 for the copper foil.

[0046] like Figures 4 to 8As shown, in a preferred embodiment of the present invention, the take-up roller 320 is preferably composed of two semi-circular rotating bodies connected as a whole by bolts, and a hidden groove is provided on the outer wall of the take-up roller 320 to accommodate and hide the bolt head, so as to avoid it from causing motion interference to the core 400 or the annular sleeve 510. A centering clamping mechanism 600 is installed between the two semi-circular rotating bodies.

[0047] like Figures 4 to 10 As shown, in a preferred embodiment of the present invention, the centering clamping mechanism 600 includes a centering shaft 610, an inner bearing 620, a rotating seat 630, an eccentric guide groove 631, a fixed seat 640, a radial guide groove 641, a sliding column 650, and a clamping block 660. The centering shaft 610 is disposed between two semi-circular rotating bodies, and the outer walls at both ends of the centering shaft 610 are connected to the inner walls at both ends of the take-up roller 320 respectively through the inner bearing 620. One end of the centering shaft 610 extends to the outside of the take-up roller 320 and is connected to an electronic control mechanism 700. The seats 630 are equidistantly distributed on the outer wall of the centering shaft 610 along the axial direction of the centering shaft 610. The fixed seat 640 is fixed on the inner wall of a semi-circular rotating body and is arranged parallel to one side of the rotating seat 630. The rotating seat 630 has eccentric guide grooves 631 circumferentially distributed that slide in cooperation with the outer wall of the sliding column 650. The fixed seat 640 has radial guide grooves 641 circumferentially distributed that slide in cooperation with the outer wall of the sliding column 650. One end of the sliding column 650 is fixed with a clamping block 660, which corresponds to the strip hole 321 opened on the take-up roller 320.

[0048] An electronic control mechanism 700 is connected to and drives the centering shaft 610 to rotate within the take-up roller 320. The centering shaft 610 drives the rotating seat 630 to rotate, which in turn drives the eccentric guide groove 631 to rotate. The eccentric guide groove 631, through rotation and cooperation with the radial guide groove 641, can drive the sliding column 650 and the clamping block 660 thereon to move along the radial direction of the take-up roller 320. This allows the clamping block 660 to extend and retract in the radial direction of the take-up roller 320, thereby completing the rapid centering and clamping of the core 400 and its rapid release. This improves the accuracy and efficiency of the core 400 installation, ensures that the core 400 remains in the center position during the winding process, and makes the wound copper foil more uniform and neat, effectively improving product quality. At the same time, it reduces manual operation, lowers labor intensity, and increases the degree of production automation.

[0049] In a preferred embodiment, the fixed seat 640, the rotating seat 630, the centering shaft 610 and the take-up roller 320 are all concentric, and the fixed seat 640 and the rotating seat 630 are preferably circular plate structures, and the rotating seat 630 has a central hole in the middle for the centering shaft 610 to pass through.

[0050] like Figures 4 to 10 As shown in a preferred embodiment of the present invention, the electrical control mechanism 700 includes a motor frame 710, a control motor 720, a flange 730, an axial sliding sleeve 740, and a fixed cylinder 750. The motor frame 710 is symmetrically fixed on the left and right sides of the frame. The control motor 720 is fixed on the motor frame 710. The flange 730 is installed on the output end of the control motor 720. The fixed cylinder 750 is fixed to the outer wall of the take-up roller 320 and the centering shaft 610 respectively by pins. The axial sliding sleeve 740 is horizontally slidably installed on one side of the fixed cylinder 750. The axial sliding sleeve 740 is fixedly connected to the flange 730 by locking bolts 760. The flange 730 is concentric with the axial sliding sleeve 740, the fixed cylinder 750, the centering shaft 610, and the take-up roller 320 respectively.

[0051] Initially, the axial sleeve 740 is located inside the fixed cylinder 750 and is not connected to the flange 730. The fixed cylinder 750 is fixed to the outer wall of the centering shaft 610 and the take-up roller 320 respectively. After the take-up roller 320 is installed in the installation limiting mechanism 800 through the outer bearing 330, the axial sleeve 740 is slid out of the fixed cylinder 750 and connected to the two flanges 730 set on the left and right sides of the frame respectively by locking bolts 760. A control motor 720 drives the axial sleeve 740 to rotate through the flange 730. The axial sleeve 740 drives the centering shaft 610 to rotate through the fixed cylinder 750, thereby completing the centering clamping and release of the core 400, improving the accuracy and efficiency of the core 400 installation, ensuring that the core 400 is always in the center position during the winding process, making the wound copper foil more uniform and neat, and effectively improving product quality.

[0052] Another control motor 720 drives the axial sliding sleeve 740 to rotate via the flange 730. The axial sliding sleeve 740 drives the take-up roller 320 to rotate via the fixed cylinder 750. The take-up roller 320 drives the core 400, the pressing mechanism 500, and the centering clamping mechanism 600 to rotate synchronously. The centering clamping mechanism 600 and an electrical control mechanism 700 connected to it can ensure that the core 400 remains stable during the copper foil winding process by rotating synchronously and in the same direction as the take-up roller 320. The core 400 can quickly wind the copper foil by cooperating with the pressure needle 570, making the copper foil tightly wound, reducing the gaps inside the copper foil roll, and thus allowing more copper foil of the same volume to be accommodated, reducing storage and transportation costs.

[0053] In a preferred embodiment, a key is installed on the outer wall of the axial sleeve 740, which slides in conjunction with a keyway on the inner wall of the fixed cylinder 750.

[0054] like Figures 4 to 11 As shown, in a preferred embodiment of the present invention, the installation limiting mechanism 800 includes a bearing seat 810, a pressure plate 820, an elastic pad 830, a stud 840, a throttle 850, and a locking plate 860. The bearing seat 810 is symmetrically fixed on the left and right sides of the frame. The pressure plate 820 is rotatably mounted on one end of the bearing seat 810. The pressure plate 820 is located on the top of the bearing seat 810. A connection port 821 is provided at one end of the pressure plate 820. An elastic pad 830 that contacts the outer bearing 330 is installed on the inner wall of the pressure plate 820. The stud 840 is rotatably mounted on the other end of the bearing seat 810. A throttle 850 is threaded onto the stud 840. The stud 840 cooperates with the connection port 821. A locking plate 860 that intermittently contacts the pressure plate 820 is fixed at the other end of the throttle 850.

[0055] When the outer bearing 330 is located inside the bearing housing 810, the connecting port 821 on the pressure plate 820 is rotated to engage with the stud 840. The throttle 850 is rotated to move the locking plate 860 closer to the pressure plate 820. The locking plate 860, by engaging with the pressure plate 820, stably fixes the outer bearing 330 inside the bearing housing 810, thereby completing the installation and fixing of the winding roller 320. This allows the core 400 to quickly complete the winding of the copper foil, improving the winding efficiency and quality of the foil production machine.

[0056] In a preferred embodiment, a central cylindrical structure is fixed at the center of the throttle 850, the inner wall of which is threadedly engaged with a stud 840, and a locking plate 860 with an annular structure is fixed at the bottom of the central cylindrical structure.

[0057] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the pressure roller assembly 310 includes a rotating frame 311, a pressure roller body 312, a pressure roller sleeve 313, and a hydraulic press 314. The rotating frame 311 and the hydraulic press 314 are symmetrically and rotatably mounted on the left and right sides of the frame. The output end of the hydraulic press 314 is connected to the middle of the rotating frame 311. The pressure roller body 312 is installed between the two rotating frames 311, and the pressure roller sleeve 313 is fixed in the middle of the pressure roller body 312.

[0058] The hydraulic press 314 can change the rotation angle of the rotating frame 311 by telescopic movement, thereby changing the position of the pressure roller body 312. When copper foil needs to be wound up, the hydraulic press 314 drives the pressure roller sleeve 313 on the pressure roller body 312 to rotate to a position that matches the core 400 through the rotating frame 311, so that it can apply a certain pressure to the copper foil during the winding process, ensuring that the copper foil is tightly attached during winding, avoiding wrinkles or looseness, and improving the winding quality of the foil production machine. When the wound core 400 needs to be replaced, the hydraulic press 314 drives the pressure roller sleeve 313 on the pressure roller body 312 to rotate above the core 400 and separate from it through the rotating frame 311, making it convenient to replace the next core 400 for new copper foil winding.

[0059] In a preferred embodiment, the hydraulic press 314 preferably employs a hydraulic telescopic system consisting of a hydraulic cylinder and a hydraulic rod, or alternatively, a pneumatic telescopic system consisting of a pneumatic telescopic cylinder and a telescopic rod.

[0060] The working principle of this invention is:

[0061] In the initial state, the take-up roller 320 is detached from the outside of the mounting and limiting mechanism 800, and one end of the centering and clamping mechanism 600 is hidden inside the take-up roller 320, so that the outer wall of the take-up roller 320 is in a smooth state, which makes it easy to fit the core 400 and the pressing mechanism 500 on the outside of the take-up roller 320.

[0062] During installation, the outer bearings 330 at both ends of the take-up roller 320 are installed in the bearing seats 810 on the left and right sides of the frame, respectively. The connecting port 821 on the pressure plate 820 is rotated to engage with the stud 840. The throttle 850 is rotated to move the locking plate 860 closer to the pressure plate 820. The locking plate 860, by engaging with the pressure plate 820, stably fixes the outer bearings 330 in the bearing seats 810, thereby completing the installation and fixing of the take-up roller 320.

[0063] After the take-up roller 320 is installed in the installation limiting mechanism 800 via the outer bearing 330, the axial sliding sleeve 740 slides out of the fixed cylinder 750 and is connected to two flanges 730 on the left and right sides of the frame via locking bolts 760. A control motor 720 drives the axial sliding sleeve 740 to rotate via the flanges 730. The axial sliding sleeve 740 drives the centering shaft 610 to rotate via the fixed cylinder 750, thereby completing the centering clamping and release of the core 400. This improves the accuracy and efficiency of the core 400 installation, ensures that the core 400 is always in the center position during the winding process, makes the wound copper foil more uniform and neat, and effectively improves product quality.

[0064] Adjust the annular sliding sleeves 510 distributed on both sides of the core 400 to ensure that the pressure needles 570 on both sides are fully and effectively located outside the core 400, and fix the annular sliding sleeves 510 to the outer wall of the take-up roller 320 with locking screws 520; before winding the copper foil, push and pull the slider 540 with the Z-shaped lever 580, so that the slider 540 drives the pressure needles 570 to separate from the outer wall of the core 400, which can facilitate the removal of the copper foil on the pressure roller assembly 310. Pulled to the outer wall of the core 400, after the starting section of the copper foil is attached to the outer wall of the core 400, the Z-shaped lever 580 is released. The spring 560 drives the slider 540 to move back quickly through its own elastic force. The slider 540 drives the pressure needle 570 to move back quickly and press the starting section of the copper foil onto the outer wall of the core 400, ensuring that the copper foil remains tightly attached during the winding process, avoiding loosening or wrinkles, and improving the winding efficiency and winding quality of the foil making machine.

[0065] During winding, two electronic control mechanisms 700 operate synchronously and in the same direction. Another control motor 720 drives the axial sliding sleeve 740 to rotate via the flange 730. The axial sliding sleeve 740 drives the winding roller 320 to rotate via the fixed cylinder 750. The winding roller 320 drives the core 400, the pressing mechanism 500, and the centering clamping mechanism 600 to rotate synchronously. The centering clamping mechanism 600 and its connected electronic control mechanism 700, by rotating synchronously and in the same direction as the winding roller 320, ensure that the core 400 rotates smoothly during the winding of the copper foil. Throughout the process, the core 400 remains stable. By cooperating with the pressure needle 570, it can quickly wind up the copper foil, making the copper foil tightly wound and reducing the gaps inside the copper foil roll. This allows the same volume of packaging to hold more copper foil of a certain length, reducing warehousing and transportation costs. After the winding is completed, the pressure needle 570, due to its small cross-sectional diameter, can quickly retract from the inside of the copper foil to the outside, facilitating the rapid winding of the next core 400 and further improving the winding efficiency of the foil production machine.

[0066] The above describes the working principle of this electrolytic copper foil production machine, which facilitates the winding of the foil.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
