Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a fabric winding and unwinding device. Background Technology

[0002] In industrial production, fabric unwinding and winding devices are widely used in various continuous processing flows, such as coating, laminating, and drying. Especially in the drying process of ceramic fiber felt rolls, it is typically necessary to unwind the rolled fabric and send it into the drying equipment, where it is dried before being rewound. Existing unwinding and winding equipment can be divided into fully automatic and semi-automatic types based on their level of automation.

[0003] Currently, fully automated unwinding and winding equipment is mostly installed on complex, continuous production lines with multiple collaborative processes. It enables automatic loading and unloading, tension control, deviation correction, and centering, significantly improving production efficiency and reducing manual intervention. However, such equipment is complex in structure, expensive to manufacture, and requires a high level of technical expertise from maintenance and operators. In applications such as drying ceramic fiber felt rolls, where the process is relatively simple and the production pace is slow, using fully automated equipment not only increases equipment investment and operating costs but also increases the overall complexity of the system, which is detrimental to process optimization and cost control.

[0004] On the other hand, while traditional semi-automatic unwinding and winding devices are simple in structure and low in cost, they generally have functional limitations. For example, tension adjustment relies on manual experience and lacks an effective correction mechanism, leading to uneven winding, wrinkles, or even deviation. Especially after the fabric has passed through the drying equipment, it is more prone to positional shifts due to temperature changes and material elasticity. If this cannot be corrected in time, it will directly affect the quality of the roll material and the efficiency of subsequent processing.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0022] like Figures 1 to 5The fabric unwinding and winding device shown includes an unwinding device 2 and a winding device 3 respectively disposed on both sides of a drying device 1, and a collecting device 4 disposed corresponding to the unwinding device 2. The unwinding device 2 includes a first support 21 and an unwinding shaft 22 disposed thereon. The unwinding shaft 22 drives the unwinding of the fabric through a first power device 23. A first transition roller group 24, a first adjusting roller 25, and a first positioning roller 26 are sequentially disposed on the first support 21 along the fabric conveying direction. The winding device 3 includes a second support 31 and a first winding shaft 32 disposed thereon. The first winding shaft 32 drives the winding of the fabric through a second power device 33. A second positioning roller 34, a second adjusting roller 35, and a second transition roller group 36 are sequentially disposed on the second support 31 along the fabric conveying direction.

[0023] This application discloses a semi-automatic unwinding and winding device that can be used for drying ceramic fiber felt rolls. The operation does not require full automation, and manual intervention is required for loading and unloading at the unwinding device 2 and the winding device 3. Compared with the fully automatic unwinding and winding device 2, in the process of drying and then rewinding the felt roll after unwinding, the semi-automatic unwinding and winding device 2 of this application meets the process requirements while having lower cost and simpler operation.

[0024] In the specific implementation process, the first power unit 23 serves as the driving force for the unwinding shaft 22, actively unwinding the upper drum. The fabric is manually pulled and sequentially wound around the first transition roller group 24, the first adjusting roller 25, and the first positioning roller 26. At the same time, the grid used to separate the fabric in the felt roll is wound onto the second take-up shaft 42, and the third power unit 43 provides the winding power. After passing through the drying equipment 1, the fabric is sequentially wound around the second positioning roller 34, the second adjusting roller 35, and the second transition roller group 36, and finally wound onto the first take-up shaft 32, with the second power unit 33 providing the winding power. The first adjusting roller 25 and the second adjusting roller 35 are used to adjust the tension of the fabric during the unwinding and winding process, respectively, to ensure the smooth operation of the unwinding and winding process.

[0025] In this embodiment, as Figure 2 As shown, the first adjusting roller 25 is disposed on the first swing frame 27, and the first swing frame 27 is rotatably connected to the first support 21. The first swing frame 27 includes two first swing arms 271 disposed opposite to each other. The two ends of the first adjusting roller 25 are rotatably connected to one end of the two first swing arms 271 respectively. The two first swing arms 271 are fixedly connected by the first connecting rod 272 and are rotatably connected to both sides of the first support 21 respectively.

[0026] See details Figure 2As shown, the first adjusting roller 25 is rotatably connected to the first support 21 via the swing arm on the first swing frame 27. The first adjusting roller 25 and the first connecting rod 272 are located at the two ends of the swing arm on the first swing frame 27, so that the first swing frame 27 remains vertical under the gravity of the first adjusting roller 25. The first adjusting roller 25 is located at the bottom of the first swing frame 27. When the fabric passes around the first adjusting roller 25, it can provide tension to the fabric under its gravity.

[0027] In this embodiment, as Figure 4 As shown, the second adjusting roller 35 is mounted on the second swing frame 37, which is rotatably connected to the second support 31 and driven to rotate by the first cylinder 373. The second swing frame 37 includes two opposing second swing arms 371, the middle of which is rotatably connected to the second support 31. The two ends of the second adjusting roller 35 are rotatably connected to one end of the second swing arm 371, and the other ends of the two second swing arms 371 are fixedly connected by the second connecting rod 372. The first cylinder 373 is mounted on the second support 31 and connected to the second connecting rod 372.

[0028] See details Figure 4 As shown, the second swing frame 37 is driven by the first cylinder 373 and the position of the second adjusting roller 35 on it is adjusted, thereby adjusting the tension of the fabric during the winding process.

[0029] Furthermore, the first transition roller group 24 includes a first guide roller 241 and a second guide roller 242 disposed between the unwinding shaft 22 and the first adjusting roller 25; the second transition roller group 36 includes a third guide roller 361 and a fourth guide roller 362 disposed between the first take-up shaft 32 and the second adjusting roller 35. By setting transition roller groups in the unwinding device 2 and the take-up device 3, the conveying path and state of the fabric are optimized.

[0030] In this embodiment, see further details. Figure 4 and Figure 5 As shown, a connecting bracket 38 is provided on the side of the second bracket 31 facing the drying equipment 1, and a second positioning roller 34 is provided on the connecting bracket 38. A correction sensor 381 is provided on the connecting bracket 38 near the end of the second positioning roller 34. The correction sensor 381 near the second positioning roller 34 detects the position of the fabric in the drying equipment 1 that guides the winding equipment 3.

[0031] Further, see Figure 5As shown, a web-correcting assembly 39 is provided at the bottom of the second bracket 31. The web-correcting assembly 39 includes a base 391 and a first guide rail 392 and a second cylinder 393 mounted thereon. The second bracket 31 is mounted on the first guide rail 392 via a first roller 394 at its bottom and is driven to move along the length direction of the first guide rail 392 by the second cylinder 393. The first guide rail 392 is arranged parallel to the first take-up shaft 32. When the fabric shifts in position in its width direction, the second cylinder 393 drives the second bracket 31 to move as a whole along the width direction of the fabric, ensuring the take-up quality of the fabric on the first take-up shaft 32.

[0032] Furthermore, a vertical baffle 395 is provided on one side of the length of the first guide rail 392. A limiting groove 396 is provided on the vertical baffle 395 corresponding to the rotation axis of the first roller 394. The first roller 394 is slidably connected to the limiting groove 396 via a support shaft 397 located at its rotation axis. The vertical baffle 395, in conjunction with its upper limiting groove 396, ensures the smooth rolling of the first roller 394 on the first guide rail 392.

[0033] In this embodiment, as Figure 3 As shown, the third support 41 is located below the first support 21, and a second guide rail 44 is provided corresponding to the third support 41. The third support 41 is tactilely connected to the second guide rail 44 via a second roller 45 at its bottom. The grid is actively wound onto the drum by the second take-up shaft 42 driven by the third power device 43, realizing the active collection of the grid. The grid collection tension can be adjusted by adjusting the motor torque of the third power device 43. An explosion-proof motor is selected to meet the CT4 explosion-proof requirements. After the grid on the drum is wound up, the third support 41 is manually pushed out from under the first support 21 along the second guide rail 44 for easy replacement of the upper drum.
