Description

Technical Field

[0001] This utility model relates to the field of floating rollers, specifically to a floating roller device for a winding machine. Background Technology

[0002] In the water-plating production of composite copper foil, a fixed-roller-to-roller winding method is used. During this winding process, wrinkles are easily formed on the film surface, which is the primary challenge affecting product yield. The wrinkles mainly stem from the following factors: First, the base film of the composite copper foil (such as PET or PP) is extremely thin and has low tensile strength, making it highly sensitive to tension fluctuations. Second, the surface of the water-plated copper foil is soft, and its adhesion is not yet stable; any minor friction, scratch, or stress concentration can lead to irreversible damage. Third, during production line operation, parallelism errors of the guide rollers, minor fluctuations in the transmission system, and uneven thickness of the film material itself can all lead to uneven lateral tension distribution, which in turn causes longitudinal wrinkles. To reduce wrinkles, the tension control during water-plating winding needs to be uniform and stable.

[0003] Therefore, a floating roller device is needed to control tension stability. Existing floating rollers are integral and have the limitation of responding to tension changes as a whole. This makes it inconvenient to finely control the lateral tension distribution of the film (especially composite copper foil). If there are wrinkles on one side of the film, it is inconvenient to make individual adjustments. Moreover, since floating rollers are generally made of rigid materials, they are prone to damage to more sensitive materials.

[0004] Therefore, it is necessary to invent a floating roller device for a winding machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a floating roller device for a winding machine. Through the cooperation of a lifting component, a self-adjusting component, and a floating roller, the floating roller is upgraded from a passive tension buffer device to an active film tension distribution management platform. It offers multiple adjustments and protects the film, thus solving the limitations of existing floating rollers, which are integral and can only respond to tension changes as a whole. This makes it difficult to finely control the lateral tension distribution of the film (especially composite copper foil). If there are wrinkles on one side of the film, it is inconvenient to make individual adjustments. Furthermore, since floating rollers are generally made of rigid materials, they are prone to damage to sensitive materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floating roller device for a winding machine, comprising: a support frame for supporting the entire device; The guide rollers, located inside the support frame, are used to guide and support the film. A floating roller, disposed between guide rollers, includes a floating fixed roller, a floating moving roller that rotates outside the floating fixed roller, and a flexible sleeve roller that is fixedly wrapped around the outside of the floating moving roller. Two lifting components are symmetrically distributed, and each lifting component is equipped with a self-adjusting component. The two self-adjusting components are connected by a floating roller, and a connecting component is provided at the connection between the self-adjusting component and the floating roller; The height of the floating roller can be adjusted by the lifting component and the self-adjusting component, thereby adjusting the membrane tension.

[0007] As a preferred embodiment of the present invention, the support frame includes a first upright plate and a second upright plate, the first upright plate and the second upright plate are symmetrically arranged, and a connecting cavity is installed in the middle part of the interior of the first upright plate and the second upright plate, and the two connecting cavities are symmetrically distributed.

[0008] As a preferred embodiment of the present invention, the guide roller includes a first fixed roller and a second fixed roller, both of which are fixedly connected between a first vertical plate and a second vertical plate. A first set of rollers is rotatably connected to the outer side of the first fixed roller, and a second set of rollers is rotatably connected to the outer side of the second fixed roller.

[0009] In a preferred embodiment of this utility model, a limiting groove is provided on the outer side of the floating fixed roller, and a limiting protrusion is fixedly connected to the inner side of the floating moving roller. The limiting protrusion cooperates with the limiting groove, and a connecting bearing is provided between the floating fixed roller and the floating moving roller.

[0010] As a preferred embodiment of this utility model, the flexible roller is made of an elastic material with a predetermined hardness. This predetermined hardness allows the flexible roller to deform under external force, thereby adapting to the unevenness of the membrane material and providing sufficient support to flatten the membrane material.

[0011] In a preferred embodiment of this utility model, the lifting assembly includes a mounting frame, which is installed inside the connecting cavity. A precision push rod is mounted on the top of the mounting frame, and an output rod is fixedly connected to the output end of the precision push rod. The output rod passes through the top of the mounting frame and a lifting block is fixedly connected to its end.

[0012] As a preferred embodiment of this utility model, the lifting block has mating grooves on both sides, and multiple rolling columns are rotatably connected to the inner sides of the mounting frame, with the rolling columns mating with the mating grooves.

[0013] In a preferred embodiment of this utility model, a fine-tuning block is slidably connected inside the lifting block. A through hole is provided inside the fine-tuning block, and a limiting rod passes through the through hole. The limiting rod is fixedly connected to the lifting block, and a return spring is sleeved on the outside of the limiting rod. The two ends of the return spring are fixedly connected to the lifting block and the fine-tuning block, respectively.

[0014] As a preferred embodiment of this utility model, the mounting frame has a lifting groove on the side near the floating roller, the lifting groove cooperates with the fine-tuning block, and a dustproof curtain is installed on the inner wall of the lifting groove.

[0015] In a preferred embodiment of this utility model, the connecting assembly includes a spherical rod, which is fixedly connected to the outer end of the fine-tuning block. An arc-shaped groove is formed on the outer side of the spherical rod, and a rotating bead is provided inside each arc-shaped groove. A spherical cover is fitted on the outer side of the spherical rod, and a clearance groove that cooperates with the rotating bead is formed on the inner side of the spherical cover. Both ends of the clearance groove are tapered. A connecting plate is fixedly connected to the end of the spherical cover, and the connecting plate is fixedly connected to the floating fixed roller. A dust cover is fitted on the outer side of the spherical rod and the spherical cover.

[0016] Compared with the prior art, the technical effects and advantages provided by this utility model in the above technical solution are as follows: By using pressure sensors to monitor the film's position on the roller surface in real time, the system can instantly identify deviation or wrinkling tendencies. Once a difference in tension is detected on both sides of the film, the PLC controller will immediately instruct the precision push rod on the side with greater tension to rise slightly, or instruct the precision push rod on the side with less tension to fall slightly, forming a small tilt angle so that the film automatically and smoothly returns to the center position. This fundamentally avoids frequent downtime, material waste, and product scrap caused by film misalignment, serpentine movement, or wrinkling. For wide-format and extremely thin composite copper foil, this is a key guarantee for achieving stable and continuous production. Specifically, two pressure sensors are installed between the floating fixed roller and the floating moving roller, located at both ends inside the floating moving roller. When the film tension does not meet the standard, the user detects the internal pressure value through the sensors and activates the precision push rod through the PLC controller to adjust the height of the floating roller, thereby adjusting the film tension. The user activates the precision push rod, which drives the lifting block at the end of the output rod to rise and fall according to the pressure value. The inner side of the mating groove on the side of the lifting block contacts the rolling column, thereby rising and falling inside the mounting frame. The height of the floating roller is set by adjusting the height of the lifting block, thus making the floating roller cooperate with the film. The flexible roller is made of silicone-free, low-exudation, and antistatic polyurethane (PU). Its surface is seamless and smooth, and its Shore A hardness is between 60° and 80°. If the film has slight lateral thickness unevenness or impurities, the surface of the flexible roller can undergo slight deformation to adapt and avoid hard scratches. When minor adjustments are needed, or when the precision push rod does not respond promptly, the fine-tuning block can float slightly up and down on the outside of the limit post for further fine-tuning. A damping telescopic component is provided between the fine-tuning block and the lifting block, and the return spring can drive the fine-tuning block to return to its original position inside the lifting block. The fine-tuning block slides inside the lifting groove for easy limiting. The dust curtain can protect the internal parts of the mounting frame from external dust, preventing it from entering and hindering the operation of internal parts, causing jamming.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides, for example Figure 1-10 A floating roller device for a winding machine, as shown, includes: Support frame 001 is used to support the entire device; The guide roller 002, located inside the support frame 001, is used to guide and support the film; The floating roller 003 is disposed between the guide rollers 002 and includes a floating fixed roller 301, a floating moving roller 302 that rotates outside the floating fixed roller 301, and a flexible sleeve roller 303 that is fixedly wrapped around the outside of the floating moving roller 302. Two lifting components 004 are symmetrically distributed, and a self-adjusting component 005 is installed inside the lifting component 004; The two self-adjusting components 005 are connected by a floating roller 003, and a connecting component 006 is provided at the connection between the self-adjusting component 005 and the floating roller 003. The height of the floating roller 003 can be adjusted by the lifting component 004 and the self-adjusting component 005, thereby adjusting the tension of the membrane material.

[0022] The user can place the film on the upper side of the first roller 202, then wrap it around the lower side of the floating roller 003, and then wrap it around the upper side of the second roller 204, and finally wind it up using a winding device. Furthermore, the support frame 001 includes a first upright plate 101 and a second upright plate 102, which are symmetrically arranged. A connecting cavity 103 is installed in the middle portion of both the first upright plate 101 and the second upright plate 102, and the two connecting cavities 103 are symmetrically distributed. The guide roller 002 includes a first fixed roller 201 and a second fixed roller 203, both of which are fixedly connected between the first upright plate 101 and the second upright plate 102. A first set of rollers 202 is rotatably connected to the outer side of the first fixed roller 201, and a second set of rollers 204 is rotatably connected to the outer side of the second fixed roller 203.

[0023] In use, the user rotates the first set of rollers 202 on the outside of the first fixed roller 201. A bearing is provided between the first fixed roller 201 and the first set of rollers 202, and a bearing is provided between the second fixed roller 203 and the second set of rollers 204 to reduce resistance and make it smoother during use. The first set of rollers 202 and the second set of rollers 204 are arranged in parallel.

[0024] The system includes a floating fixed roller 301, a floating moving roller 302 rotating outside the floating fixed roller 301, and a flexible sleeve roller 303 fixedly wrapped around the floating moving roller 302. The flexible sleeve roller 303 is made of an elastic material with a predetermined hardness. This predetermined hardness allows the flexible sleeve roller to deform under external force, thereby adapting to the unevenness of the film material and providing sufficient support to flatten the film. The flexible sleeve roller 303 is made of a silicone-free, low-exudation, antistatic special rubber such as polyurethane (PU), with a seamless and smooth surface and a Shore A hardness between 60° and 80°. If the film has slight lateral thickness unevenness or impurities, the surface of the flexible sleeve roller 303 can undergo slight deformation to adapt, avoiding hard scratches.

[0025] In the above structure, a limiting groove 305 is provided on the outer side of the floating fixed roller 301, and a limiting protrusion 306 is fixedly connected to the inner side of the floating moving roller 302. The limiting protrusion 306 cooperates with the limiting groove 305, and a connecting bearing 304 is provided between the floating fixed roller 301 and the floating moving roller 302.

[0026] In use, the floating moving roller 302 rotates outside the floating fixed roller 301. The connecting bearing 304 can reduce friction and facilitate rotation. The limiting protrusion 306 and the limiting groove 305 can prevent external dust from entering and prevent contamination of the internal lubricating oil. The floating fixed roller 301 is arranged in parallel with the first set of rollers 202 and the second set of rollers 204.

[0027] As a further optimization of this utility model, the lifting assembly 004 includes a mounting frame 401, which is installed inside the connecting cavity 103. A precision push rod 402 is mounted on the top of the mounting frame 401, and an output rod 403 is fixedly connected to the output end of the precision push rod 402. The output rod 403 passes through the top of the mounting frame 401 and a lifting block 404 is fixedly connected to its end. The lifting block 404 has mating grooves 405 on both sides, and multiple rolling columns 406 are rotatably connected to both sides of the interior of the mounting frame 401, with the rolling columns 406 engaging with the mating grooves 405.

[0028] Two pressure sensors are installed between the floating fixed roller 301 and the floating moving roller 302, located at both ends inside the floating moving roller 302. The output of the pressure sensors is connected to the PLC controller. When the tension of the film does not meet the standard, the user detects the internal pressure value through the sensors and activates the precision push rod 402 through the PLC controller according to the pressure value. The precision push rod 402 is an electric push rod, which adjusts the height of the floating roller 003, thereby adjusting the film tension. When the user activates the precision push rod 402, it drives the lifting block 404 at the end of the output rod 403 to rise and fall according to the pressure value. The inner side of the mating groove 405 on the side of the lifting block 404 contacts the rolling column 406, thereby rising and falling inside the mounting frame 401. The height of the floating roller 003 is set by adjusting the height of the lifting block 404, so that the floating roller 003 can cooperate with the film. The pressure sensor monitors the film's position on the roller surface in real time, allowing the system to instantly identify any deviation or wrinkling tendency. Once a tension difference is detected on both sides of the film, the PLC controller immediately instructs the precision push rod 402 on the side with higher tension to rise slightly, or instructs the precision push rod 402 on the side with lower tension to fall slightly, creating a small tilt angle that allows the film to automatically and smoothly return to its center position. This fundamentally avoids frequent downtime, material waste, and product scrap caused by film deviation, serpentine movement, or wrinkling. For wide-format, extremely thin composite copper foil, this is a key guarantee for achieving stable and continuous production.

[0029] In a further optimization of the above embodiment, a fine-tuning block 501 is slidably connected inside the lifting block 404. A through hole 502 is provided inside the fine-tuning block 501, and a limiting rod 503 passes through the through hole 502. The limiting rod 503 is fixedly connected to the lifting block 404. A return spring 504 is sleeved on the outside of the limiting rod 503. The two ends of the return spring 504 are fixedly connected to the lifting block 404 and the fine-tuning block 501, respectively. A lifting groove 505 is provided on the side of the mounting frame 401 near the floating roller 003. The lifting groove 505 cooperates with the fine-tuning block 501. A dustproof curtain 506 is installed on the inner wall of the lifting groove 505.

[0030] When the device requires minor adjustments, or when the precision push rod 402 does not respond in time, the fine-tuning block 501 can float slightly up and down on the outside of the limit rod 503 to facilitate further fine-tuning. A damping telescopic component is provided between the fine-tuning block 501 and the lifting block 404. The return spring 504 can drive the fine-tuning block 501 to reset inside the lifting block 404. The fine-tuning block 501 slides inside the lifting groove 505 to facilitate limiting. The dust curtain 506 can protect the internal parts of the mounting frame 401 to prevent external dust from entering and hindering the operation of internal parts, causing jamming.

[0031] In the above structure, the connecting component 006 includes a spherical rod 601, which is fixedly connected to the outer end of the fine-tuning block 501. The outer side of the spherical rod 601 is provided with an arc-shaped groove, and a rotating bead 602 is provided inside each arc-shaped groove. A spherical cover 603 is fitted on the outer side of the spherical rod 601. An avoidance groove 604 that cooperates with the rotating bead 602 is provided on the inner side of the spherical cover 603. Both ends of the avoidance groove 604 are tapered. A connecting plate 605 is fixedly connected to the end of the spherical cover 603. The connecting plate 605 is fixedly connected to the floating fixed roller 301. A dust cover 606 is fitted on the outer side of the spherical rod 601 and the spherical cover 603.

[0032] When the pressure at both ends of the floating roller 003 is different, the user can adjust the precision push rods 402 on both sides according to the pressure value to operate them separately. At this time, the floating roller 003 tilts, and the connecting plates 605 at both ends of the floating fixed roller 301 drive the spherical cover 603 to rotate outside the spherical rod 601. This facilitates the compensation of the tilt angle caused by the rotation of the floating fixed roller 301. The clearance groove 604 is set to a shape with a smooth middle and tapered ends, that is, the spherical cover 603 can slide a small distance outside the spherical rod 601 without falling off. The outer dust cover 606 is made of cloth, which can protect the parts and prevent the internal parts from being contaminated.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
