Description

Technical Field

[0001] This application relates to the field of ultra-thin stainless steel production, and in particular to a double-opening automatic switching rewinding device. Background Technology

[0002] In the field of ultra-thin stainless steel production, existing technologies focus on developing products with a mirror-like finish. These products, named for their smooth, mirror-like surface, are widely used in areas with extremely high requirements for surface smoothness, such as exterior decoration of new energy vehicles and smooth reflective components for high-end consumer goods. With the continuous growth of market demand, higher requirements are being placed on the production efficiency and quality of these products. In the processing flow, to ensure the product achieves a mirror-like finish, multiple fine grinding processes are required, accompanied by rigorous subsequent processing such as washing, drying, and heat treatment. After completing these processes, how to efficiently and without damage re-roll the sheet metal has become a pressing technical challenge.

[0003] Currently, the industry commonly uses shaft-type winding devices, which work by winding stainless steel strips via a drive shaft after all surface treatments are completed. However, when a roll of material is wound up, the production line (including upstream processes such as grinding, cleaning, and heat treatment) needs to be stopped or its efficiency reduced to replace the winding shaft. This process limits production efficiency, and shutdowns after critical processes like heat treatment severely impact the surface quality of ultra-thin stainless steel sheets, failing to meet the demands of continuous, stable, and efficient production lines for ultra-thin stainless steel production. Utility Model Content

[0004] To address the problem of low winding efficiency in the production of ultra-thin stainless steel, this application provides a double-opening automatic switching winding device.

[0005] The technical solution of the double-opening automatic switching winding device provided in this application is as follows: A double-opening automatic switching winding device includes a base and a winding mechanism slidably mounted on the base; the winding mechanism includes at least two drive winding seats, each drive winding seat is slidably moved from the base through a drive component, and the drive winding seat is provided with a winding roller for winding ultra-thin stainless steel. When winding, only one drive winding seat's winding roller performs winding. When the winding roller of one drive winding seat completes winding, the drive component drives the drive winding seat away from the ultra-thin stainless steel discharge area. At the same time, another drive component drives the drive winding seat to be wound to move until the winding roller contacts the ultra-thin stainless steel and winds it up.

[0006] By adopting the above technical solution, the double-opening automatic switching winding device sets at least two drive winding seats. The drive assembly makes each drive winding seat slide, so that only one drive winding seat can be used for winding. After one winding roll finishes winding, the drive assembly can drive the wound drive winding seat away from the discharge area, and at the same time drive the drive winding seat to be wound to move so that the winding roll contacts the ultra-thin stainless steel and continues to wind. This alternating operation method can effectively ensure the continuity of the winding process, reduce downtime caused by changing winding rolls, and improve winding efficiency.

[0007] Optionally, the drive take-up station is equipped with a drive component that drives the take-up roller to rotate.

[0008] By adopting the above technical solution, a driving component is set in the drive winding seat to drive the winding roller to rotate, so that the winding roller can operate actively to realize the winding operation of ultra-thin stainless steel. This driving method can provide stable and controllable power for the winding process, ensure the smooth winding operation, guarantee winding quality and efficiency, and facilitate flexible adjustment of parameters such as winding speed according to actual needs.

[0009] Optionally, a slider module is provided on the side of the winding drive unit near the base, and the base is provided with a slide rail for the slider module to slide and connect.

[0010] By adopting the above technical solution, at least one set of sliders is provided on the side of the winding drive seat near the base, and the base is provided with a slide rail for the sliders to slide and connect. This structure enables a stable sliding connection between the winding drive seat and the base, allowing the winding drive seat to maintain a smooth and accurate trajectory during movement, reducing movement deviation and shaking, ensuring the positional accuracy of the winding drive seat and its winding roller during operation, and thus improving the stability and reliability of the winding process.

[0011] Optionally, the drive assembly includes a lead screw, two supports, a sleeve, and a drive motor for driving the lead screw to rotate. The two supports are mounted on a base and have mounting holes. The lead screw passes through the two mounting holes and is rotatably connected to the supports. The sleeve passes through the lead screw and is threadedly engaged with it. The sleeve is located between the two supports. The sleeve is fixedly connected to a drive take-up unit. The drive motor drives the lead screw to rotate, thereby causing the drive take-up unit to move away from or towards the ultra-thin stainless steel discharge area.

[0012] By adopting the above technical solution, the drive winding seat can move stably and accurately on the lead screw, allowing the drive winding seat to move away from or closer to the ultra-thin stainless steel discharge area according to actual needs. This effectively improves the flexibility and accuracy of winding and unwinding operations, helps ensure the stability of ultra-thin stainless steel during winding and unwinding, and thus improves production efficiency and product quality.

[0013] Optionally, a support assembly is also included, which includes a tray, a lifting component, and a base. The base is slidably connected to the base, and the lifting component is installed on the base. The lifting component drives the tray to rise and fall. When the winding seat needs to unload material, the lifting component drives the tray to contact the ultra-thin stainless steel coil.

[0014] By adopting the above technical solution, the position of the support table can be flexibly adjusted to make it contact the ultra-thin stainless steel coil when the winding seat is unloading, so as to provide stable support for the ultra-thin stainless steel coil. This effectively avoids the deformation or shaking of the stainless steel coil due to lack of support during the unloading process, ensuring the stability and safety of the unloading operation and improving the reliability and efficiency of the overall production process.

[0015] Optionally, the side of the platform near the bottom is provided with at least one guide post for guiding the lifting and lowering of the platform, and the side of the bottom near the platform is provided with a guide groove for the guide post to be embedded.

[0016] By adopting the above technical solution, the guiding function of the towing platform during the lifting process is realized, which effectively enhances the stability of the towing platform lifting, reduces the shaking and deviation during the lifting process, and ensures that the towing platform can be lifted and lowered smoothly and accurately.

[0017] Optionally, a pulley module is provided on the side of the support away from the platform, and the support slides on the base surface via the pulley module.

[0018] By adopting the above technical solution, the support component can slide on the base surface through the pulley module, thereby moving back and forth between the two drive winding seats and quickly supporting the wound steel coil.

[0019] Optionally, the side of the tray away from the bottom has a support groove for supporting the stainless steel coil.

[0020] By adopting the above technical solution, the contact area between the drag table and the steel coil is effectively increased, making the steel coil more evenly stressed during the support process. This avoids deformation or damage caused by localized stress concentration due to insufficient contact area, further ensuring the stability and safety of the steel coil during feeding and unwinding, and improving product quality and the reliability of production operations.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting at least two drive take-up stations and using drive components to achieve sliding of each drive take-up station, the take-up operation is carried out alternately, which effectively ensures the continuity of the take-up process, reduces downtime caused by changing take-up rollers, and improves take-up efficiency.

[0022] 2. The winding drive unit and the base form a stable sliding connection through the slider module and the slide rail, so that the winding drive unit maintains a smooth and precise trajectory during movement, reducing movement deviation and shaking.

[0023] 3. The bottom support slides on the base surface via a pulley module, allowing the support component to quickly move back and forth between the two drive winding seats, providing timely support for the wound steel coil. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0032] This application discloses a double-opening automatic switching rewinding device for rewinding ultra-thin stainless steel conveyed from a production line. (See also...) Figure 1 The double-opening automatic switching winding device includes a base 1, a winding mechanism 2, and a support assembly 3 for supporting the steel coil.

[0033] Reference Figure 1 and Figure 2 The winding mechanism 2 includes at least two drive winding seats 21. In this embodiment, two drive winding seats 21 are preferred. The two drive winding seats 21 are arranged along the length direction of the base 1. Each drive winding seat 21 is provided with a winding roller 211 and a drive member 212 for driving the winding roller 211 to rotate. The winding rollers 211 of the drive winding seat 21 are all facing the ultra-thin stainless steel in the discharge area and are correspondingly arranged on both sides of the ultra-thin stainless steel. When winding, only one winding roller 211 of the drive winding seat 21 contacts and winds the ultra-thin stainless steel strip. In this embodiment, the drive member 212 is preferably a motor, which facilitates driving the winding roller 211 to rotate so as to realize the winding of the ultra-thin stainless steel. The discharge area of ​​this application refers to the area where the ultra-thin stainless steel is located after being processed by grinding, cleaning, heat treatment and other processes, and is also the area where the ultra-thin stainless steel to be wound is located.

[0034] Reference Figure 3 To ensure smooth sliding of the drive take-up unit on the base, the base is equipped with two sets of slide rails 11 for each drive take-up unit to slide. The two sets of slide rails 11 are parallel to the lead screw 221. Correspondingly, each drive take-up unit 21 has two sets of slider modules 23 fixedly installed on the side closest to the base, which cooperate with the slide rails 11. Each set of slider modules 23 contains three sliders 231. The cooperation between the sliders 231 and the slide rails 11 enables the drive take-up unit 21 to maintain a stable trajectory during movement, reducing deviations and shaking during movement, and ensuring the positional accuracy of the drive take-up unit 21 and the take-up roller 211 during operation.

[0035] Reference Figure 4The drive take-up holder 21 slides on the base 1 via drive components 22. There are two sets of drive components 22, with each drive take-up holder 21 equipped with one set. Each drive component 22 includes a lead screw 221, two supports 222, a sleeve 223, and a drive motor 224. The base 1 has a mounting groove 12 along the axis of the take-up roller 211 on the side near the drive take-up holder 21. The two supports 222 are fixedly installed in the mounting groove 12, and each support has mounting holes. The lead screw 221 is parallel to the axis of the take-up roller 211 and passes through the mounting holes of the two supports 222. The lead screws 221 of both sets of drive components 22 are located on the same straight line, and the length of each lead screw 221 is less than the total length of the base 1. The lead screw 221 and the supports 222 are rotatably connected. A lead screw 221 passes through the inner wall of a sleeve 223, and the sleeve 223 is threadedly engaged with the lead screw 221. The sleeve 223 is located between two supports 222. The outer wall of the sleeve 223 is fixedly connected to the drive take-up seat 21. The end of the sleeve 223 away from the base 1 is fixedly connected to the drive take-up seat 21. The drive motor 224 drives the lead screw 221 to rotate. When the lead screw 221 rotates, due to the threaded engagement, the sleeve 223 will move axially along the lead screw 221, thereby causing the drive take-up seat 21 to move away from or towards the ultra-thin stainless steel discharge area.

[0036] During the winding operation, only one winding roller 211 of the drive winding station 21 is in the winding state. After the winding roller 211 of one drive winding station 21 completes the winding task, the drive assembly 22 drives the drive winding station 21 away from the ultra-thin stainless steel output area and supports the steel coil through the support assembly 3, providing stable support for the steel coil, and then the steel coil is transferred. At the same time as the drive winding station 21 moves away from the ultra-thin stainless steel output area, another drive winding station 21 to be wound moves to the steel strip winding position through the action of the drive assembly 22, and drives the winding roller 211 through the drive component 212 to start winding the steel strip conveyed on the production line. This alternating operation mode ensures the continuity of the winding process, effectively reduces the downtime caused by changing the winding roller 211, and thus significantly improves the winding efficiency.

[0037] Reference Figure 1 and Figure 5The unwinding and winding device also includes a support assembly 3, which is located between two drive winding seats 21. The support assembly 3 is used to provide auxiliary support for the steel coil when the drive winding seats 21 are unwinding. The support assembly 3 includes a platform, a lifting component 32, and a base 33. The base 33 is slidably connected to the base 1. The lifting component 32 is specifically a cylinder, which is fixed to the base 33. The cylinder piston rod is fixedly connected to the side of the platform near the base 33, and is used to drive the platform 31 to move up and down. When the ultra-thin stainless steel coil obtained from winding needs to be unloaded, the lifting component 32 will drive the platform 31 to rise until the platform 31 contacts the ultra-thin stainless steel coil, thereby providing stable support for the ultra-thin stainless steel coil and preventing it from falling during the unloading process.

[0038] Reference Figure 1 and Figure 5 To further enhance the stability of the platform's lifting and lowering, four guide pillars 311 are extended from the side of the platform adjacent to the base 33. Both the platform and the base 33 are preferably quadrilateral structures, with the four guide pillars 311 located at the four corners of the platform. The side of the base 33 closest to the platform has guide grooves 331 corresponding to the four guide pillars 311. The guide pillars 311 are embedded in or pass through the guide grooves 331, achieving a plug-in connection between the platform and the base 33. During the lifting and lowering process of the platform, the guide pillars 311 embedded in the guide grooves 331 guide the platform, improving the stability and accuracy of the lifting and lowering.

[0039] Reference Figure 1 and Figure 5 To enable flexible movement of the support assembly 3 on the base 1, two sets of pulley modules 34 are provided on the side of the base 33 away from the guide post 311. These two sets of pulley modules 34 are symmetrically arranged on the side of the base 33 adjacent to the drive winding seat 21. Each set of pulley modules 34 includes two spaced-apart pulleys 341, which are fixedly connected to the base 33. Through the rolling action of the pulleys 341, the support assembly 3 can slide on the base 1 according to actual production needs, facilitating support operations for ultra-thin stainless steel coils at different positions.

[0040] Reference Figure 1 The support table has a support groove 312 on the side away from the bottom support 33. The support groove 312 is trapezoidal in shape and is adapted to the size and shape of the ultra-thin stainless steel coil after winding. When the support table 31 rises to contact the ultra-thin stainless steel coil, the support groove 312 can better fit the ultra-thin stainless steel coil, providing it with uniform and stable support force, preventing the steel coil from rolling off, and ensuring the stability and safety of the ultra-thin stainless steel coil during winding and unloading.

[0041] The implementation principle of the above embodiment is as follows: At the beginning of the winding operation, the winding roller 211 of one of the driving winding seats 21 in the device winds the steel strip conveyed on the production line under the action of the driving component 212, while the other driving winding seat 21 is in a standby state. When the winding roller 211 of the driving winding seat 21 finishes winding, the driving motor 224 in its corresponding driving component 22 operates, driving the lead screw 221 to rotate. Because the lead screw 221 is threadedly engaged with the sleeve 223, the sleeve 223 will be displaced along the axial direction of the lead screw 221. The displacement of the sleeve 223 drives the driving winding seat 21 away from the ultra-thin stainless steel output area. At the same time, the support component 3 slides to the bottom of the steel coil through the pulley 341, the cylinder piston rod extends, the driving platform 31 rises along the guide column 311, and the support groove 312 contacts the steel coil, providing stable support for the steel coil. Afterwards, the support component 3 and the steel coil can be transferred away with the help of external transfer equipment.

[0042] During the above process, another drive winding seat 21 to be wound up drives the lead screw 221 to rotate through the drive motor 224 of its drive assembly 22, so that the sleeve 223 drives the drive winding seat 21 to the steel strip winding position. The drive component 212 drives the winding roller 211 to start winding, realizing alternating operation, ensuring winding continuity, and improving winding efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
