Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, specifically a tower rewinding machine for ultra-wide stripe. Background Technology

[0002] In the power cable manufacturing industry, the wrapping process is a key step in ensuring the insulation and protective performance of cables. Traditionally, wrapping tape is supplied in the form of sheet reels, especially for wide cables exceeding 40mm in width. With the increasing demands for production efficiency and continuous operation in the cable industry, and the growing market demand for long-length cables, developing specialized rewinding equipment capable of converting sheet reels into tower-type reels with greater tape capacity has become an important technological development direction for improving the automation level and production efficiency of the wrapping process.

[0003] According to CN113247700B, an automatic rewinding machine for wires and cables is disclosed. This technology discloses that "an automatic rewinding machine for wires and cables has an electric push rod and a controller respectively installed on the upper end of the base. A tensioning frame is installed at the top of the electric push rod. A conductor roller is rotatably mounted on the inner wall of the tensioning frame. A tension detection component is installed at the upper end of the tensioning frame. A wire locking box is installed above the side wall of the tensioning frame. The wire locking box has an opening and a wire locking component is installed on the wire locking box. Tensioning rollers are installed on both sides above the tensioning frame, and the tensioning rollers rotate on both sides." The technical solution includes a mounting frame, a reverse lifting assembly between the mounting frames on both sides of the tensioning rollers, and the bottom end of the reverse lifting assembly is set on the base. It has the technical effects of "the proximity switch on the tensioning frame and the photoelectric switch group in the locking box determine whether the passing wire is disconnected or loose, and make appropriate adjustments to the tension of the motor or tensioning frame in the rewinding machine. When the cable reel stops, the controller will de-energize the electromagnet, thereby fixing the wire clamp plate to the wire and preventing the wire from loosening during the rewinding process".

[0004] Traditional sheet reels have limited storage capacity due to their flat structure, requiring frequent production interruptions for reel replacement during the wrapping process. This not only severely impacts the continuous operation efficiency of the production line but may also lead to joints between wrapping layers, affecting product quality. Furthermore, wide strips are prone to lateral shifts and vibrations during high-speed transport due to their wide width. Additionally, dust and debris generated during processing continuously accumulate on the strip surface. All these factors directly affect the accuracy of the wrapping process and the insulation performance of the final product. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tower-type rewinding machine for ultra-wide strip materials. It adopts an integrated dust removal and guide belt system to simultaneously clean the surface of the strip material during the conveying process. Through the coordinated control of the transverse and longitudinal slide tables, it achieves precise spiral arrangement of the strip material, efficiently converting the sheet-like strip reel into a tower-type roll with a larger storage capacity, ensuring a stable and efficient rewinding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tower-type rewinding machine for ultra-wide strip, comprising a base frame, a support fixed to the top of the base frame, and a rewinding mechanism mounted on the support for rewinding the strip. The rewinding mechanism includes:

[0007] The main components include a belt feeding and discharging component mounted on a support for belt feeding and discharging operations, and a belt take-up component mounted on the support for belt take-up operations.

[0008] The guide assembly includes a crossbeam mounted on the unloading belt component. Several guide rollers are rotatably mounted on the front end of the crossbeam. The guide rollers have circumferentially distributed air holes. The rear ends of the several guide rollers are connected by the same air pipe. A connector is fixed to the right end of the air pipe. A belt clamping component is provided on the crossbeam for fixing the belt when the machine stops.

[0009] Preferably, the clamping component includes an upper mounting plate fixed to the top of the cross frame, a cylinder mounted at the bottom of the upper mounting plate, an upper pressure head fixed at the output end of the cylinder, a lower mounting plate fixed at the bottom of the cross frame, and a lower pressure head fixed at the top of the lower mounting plate.

[0010] Preferably, the discharge belt component includes a longitudinal linear slide mounted on the outer wall of the right end of the bracket, a transverse linear slide mounted on the slider of the longitudinal linear slide, a vertical frame mounted on the slider of the transverse linear slide, and the horizontal frame fixed to the upper end of the vertical frame, and a position sensor mounted on the horizontal frame.

[0011] Preferably, the tape feeding component further includes an extension frame fixed to the outer wall of the right end of the upright frame. A first bearing is fixed to the outer wall of the extension frame, and a tape feeding shaft is rotatably mounted on the first bearing.

[0014] Beneficial effects

[0015] This invention provides a tower-type rewinding machine for ultra-wide strip materials. Compared with the prior art, it has the following advantages:

[0016] 1. Multiple guide rollers installed at the front end of the crossbeam precisely guide the belt's trajectory. Circular arrays of air holes on the surface of these rollers connect to a shared air pipe. When the connector is connected to a dust collection device, the rotating guide rollers generate continuous negative pressure through the air holes, simultaneously adsorbing surface dust as the belt passes through. This integrated dust collection design not only solves the problem of belt misalignment during transport but also enables online cleaning during production, avoiding the drawbacks of traditional external dust collection devices such as large space requirements and incomplete cleaning.

[0017] 2. The wrapping tape is moved back and forth in a horizontal reciprocating motion by a transverse linear slide table to arrange the tape, achieving a precise spiral arrangement of the tape on the take-up drum, and transforming the original sheet-like wrapping tape reel into a tower-type roll with a larger tape storage capacity; the wrapping tape is moved up and down in a vertical longitudinal motion by a longitudinal linear slide table to maintain a set minimum distance between the guide component and the tape on the inner support tensioning device, and the minimum distance is controlled by a position sensor.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a tower-type rewinding machine for ultra-wide strip, including a base frame 1, a support 2 fixed on the top of the base frame 1, and a rewinding mechanism 3 disposed on the support 2 for rewinding the strip. The rewinding mechanism 3 includes:

[0025] The main component 31 includes a tape feeding and discharging component 311 disposed on the support 2 and used to realize tape feeding and discharging operations, and a tape take-up component 312 disposed on the support 2 and used to realize tape take-up operations.

[0026] The guide assembly 32 includes a crossbeam 321 mounted on the unloading belt component 311. Several guide rollers 322 are rotatably mounted on the front end of the crossbeam 321. The guide rollers 322 are provided with circumferentially distributed air holes 323. The rear ends of the several guide rollers 322 are connected by the same air pipe 324. A connector 325 is fixed to the right end of the air pipe 324. The crossbeam 321 is provided with a belt clamping component 327 for fixing the belt when the machine stops.

[0027] In this embodiment, multiple guide rollers 322 installed at the front end of the crossbeam 321 precisely guide the running trajectory of the belt. The guide rollers 322 have a circumferential array of air holes 323 on their surface connected to a shared air pipe 324. When the connector 325 is connected to a dust collection device, the rotating guide rollers 322 generate a continuous negative pressure through the air holes 323, simultaneously adsorbing surface dust as the belt passes by. This integrated dust collection design not only solves the problem of belt misalignment during transport but also enables online cleaning during production, avoiding the disadvantages of traditional external dust collection devices such as large space requirements and incomplete cleaning.

[0028] Specifically, the clamping component 327 includes an upper mounting plate 3271 fixed to the top of the cross frame 321, a cylinder 3272 mounted at the bottom of the upper mounting plate 3271, an upper pressure head 3273 fixed at the output end of the cylinder 3272, a lower mounting plate 3274 fixed at the bottom of the cross frame 321, and a lower pressure head 3275 fixed at the top of the lower mounting plate 3274.

[0029] In this embodiment, when the equipment stops, the upper pressure head 3273 is driven to move downward by the output end of the cylinder 3272, so that the upper pressure head 3273 and the lower pressure head 3275 clamp and fix the belt between them, ensuring that the belt does not loosen when the equipment stops.

[0030] Specifically, the discharge belt component 311 includes a longitudinal linear slide 3111 installed on the outer wall of the right end of the bracket 2, a transverse linear slide 3112 installed on the slider of the longitudinal linear slide 3111, a vertical frame 3113 installed on the slider of the transverse linear slide 3112, and a horizontal frame 321 fixed to the upper end of the vertical frame 3113. A position sensor 33 is installed on the horizontal frame 321.

[0031] In this embodiment, the lateral linear slide 3112 is used to move the wrapping tape back and forth in a reciprocating motion to arrange the tape, thereby achieving a precise spiral arrangement of the tape on the take-up drum and transforming the original sheet-like tape reel into a tower-type roll with a larger tape storage capacity. The longitudinal linear slide 3111 is used to move the wrapping tape vertically up and down, so that the guide component 32 and the tape on the inner support tensioning device 3123 maintain a set minimum distance, which is controlled by the position sensor 33.

[0032] Specifically, the tape feeding component 311 also includes an extension frame 3114 fixed to the outer wall of the right end of the upright frame 3113. A first bearing seat 3115 is fixed to the outer wall of the extension frame 3114. A tape feeding shaft 3116 is rotatably mounted on the first bearing seat 3115. A magnetic powder brake 3117 is installed at the rear end of the first bearing seat 3115 and is used to drive the tape feeding shaft 3116. An air expansion shaft 3118 is installed at the front end of the tape feeding shaft 3116.

[0033] In this embodiment, constant tension tape release control is achieved by fixing the original wrapping tape to the air expansion shaft 3118 and controlling the tension of the tape release shaft 3116 through the magnetic powder brake 3117. The instantaneous response characteristics of the magnetic powder brake 3117 effectively avoid the problem of stretching deformation or loosening of the tape due to tension fluctuations, which is especially suitable for high-precision rewinding of ultra-wide tape.

[0034] Specifically, the belt retractor 312 includes a second bearing 3121 fixed to the top of the bracket 2, a shaft 3122 rotatably mounted on the second bearing 3121, an internal support tensioning device 3123 fixed to the front end of the shaft 3122, and a drive component 3124 mounted on the base frame 1 for driving the shaft 3122.

[0035] In this embodiment, the winding drum is fixed on the inner support tensioning device 3123, and the winding drum on the inner support tensioning device 3123 is rotated by the driving member 3124 driving 3122. This achieves the winding operation.

[0036] Specifically, the guide assembly 32 also includes a rotary joint 326 installed between the guide roller 322 and the air pipe 324 to enable gas conduction when the guide roller 322 is rotating.

[0037] In this embodiment, the rotary joint 326 adopts a dynamic sealing structure. Its stationary end is connected to the fixed pipeline of the air pipe 324, while the rotating end is connected to the axial air cavity of the guide roller 322. This ensures that while the guide roller 322 completes the function of guiding the strip, the air holes 323 distributed in a circular array on its surface can continuously generate a stable negative pressure adsorption force.

[0038] The working principle and usage process of this utility model are as follows: First, by fixing the original wrapping tape to the air expansion shaft 3118, the tension of the unwinding shaft 3116 is controlled by the magnetic powder brake 3117 to achieve constant tension unwinding control; then, the take-up drum is fixed to the inner support tensioning device 3123, and the drive component 3124 drives 3122 to rotate the take-up drum on the inner support tensioning device 3123 to achieve the take-up operation;

[0039] Meanwhile, the lateral linear slide 3112 enables the wrapping tape to move back and forth laterally for tape arrangement, achieving precise spiral arrangement of the tape on the take-up drum, transforming the original sheet-like wrapping tape reel into a tower-type roll with a larger tape storage capacity; the longitudinal linear slide 3111 enables the wrapping tape to move up and down longitudinally, maintaining a set minimum distance between the guide assembly 32 and the tape on the inner support tensioning device 3123, with the minimum distance controlled by the position sensor 33;

[0040] Furthermore, multiple guide rollers 322 installed at the front end of the cross frame 321 precisely guide the running trajectory of the belt. The circumferential array of air holes 323 on the surface of the guide rollers 322 are connected to a common air pipe 324. When the connector 325 is connected to the dust collection equipment, the rotating guide rollers 322 generate a continuous negative pressure through the air holes 323, which simultaneously adsorbs the dust on the surface of the belt as it passes by.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
