Description

Technical Field

[0001] This utility model relates to the field of fiber fabric production technology, and more specifically, to a winding device with controllable tension of ultrafine fibers. Background Technology

[0002] Microfiber is a type of fabric with a fiber diameter between 0.1 and 0.5 denier and less than 5 micrometers. Its adsorption capacity, water absorption speed, and water absorption volume are 7 times that of ordinary fibers. During the production process, microfiber fabrics usually require the use of a winding device to wind up the formed fabric.

[0003] Chinese patent CN217837752U discloses a winding device for chemical fiber fabrics, including a fixed side plate. A motor is installed on the side wall of the fixed side plate, and the output shaft of the motor is fixedly connected to one end of a winding roller. One end of the winding roller is rotatably connected to the fixed side plate. A material unloading mechanism sleeved on the outer wall of the winding roller is fixedly provided on the side wall of the fixed side plate near the motor. A guide roller is also rotatably connected to the side wall of the fixed side plate, and a gear is fixedly connected to one end of the guide roller. However, when using this device to wind the fabric into the winding roller, it cannot apply an adjustable tension to the fabric, making the fabric relatively loose during the winding process. This leads to wrinkles easily forming on the winding roller, affecting the winding effect. Utility Model Content

[0004] This invention provides a fine fiber tension controllable winding device, which solves the technical problem in the prior art that the fabric cannot be subjected to adjustable tension during the winding process, which leads to wrinkles easily forming on the winding roller.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A tension-controllable winding device for ultrafine fibers includes a base, on which a first bracket and a second bracket are mounted. Mounting plates are rotatably connected to both sides of the first bracket, and a winding roller is mounted between the two sets of mounting plates. A drive motor is also mounted on the first bracket, with one end of the output shaft of the drive motor connected to one side of the mounting plate. An insertion groove is provided inside the winding roller, and a clamping assembly is provided on the winding roller to fix and press the fiber fabric passing through the insertion groove. A set of support rollers is rotatably connected to the inner wall of the second bracket, and a first electric telescopic rod is mounted at the top of the second bracket. One end of the output shaft of the first electric telescopic rod is connected to a first connecting frame, and a pressure roller is rotatably connected to the first connecting frame. A transmission assembly is provided between one side of the support roller and one side of the mounting plate. A second electric telescopic rod is mounted at the top between the first and second brackets, with one end of the output shaft of the second electric telescopic rod fixedly connected to a second connecting frame, and a lifting roller is rotatably mounted on the second connecting frame.

[0007] Furthermore, the transmission assembly includes a first pulley fixedly connected to one side of the mounting plate, a second pulley fixedly connected to one side of the support roller, and a transmission belt sleeved between the first pulley and the second pulley.

[0008] Furthermore, the clamping assembly includes a sliding groove disposed on the take-up roller and connected to the insertion groove, a pressure block slidably disposed inside the sliding groove, mounting holes being provided on both sides of the pressure block, and threaded holes corresponding to the mounting holes being provided on both sides of the insertion groove.

[0009] Furthermore, a number of bolt holes are provided between the mounting plate and both sides of the take-up roller, and the positions of the bolt holes between the mounting plate and the take-up roller correspond to each other.

[0010] Furthermore, a scale rod is provided on one side of the base, and a pointer for pointing to the scale rod is provided on one side of the second connecting frame.

[0011] Furthermore, the surface of the support roller is provided with structural texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the take-up roller can take up the fabric, and the support roller and the pressure roller can clamp the fabric, so that the fabric between the take-up roller and the support roller maintains a fixed length. By controlling the lifting roller to abut against the fabric between the take-up roller and the support roller, a certain tension can be applied to the fabric. The user can flexibly adjust the tension on the fabric when it is taken up onto the take-up roller according to the material and thickness of the fabric by adjusting the height of the lifting roller. This ensures that the fabric is kept taut before being taken up onto the take-up roller, and does not wrinkle on the take-up roller due to slack, thus ensuring the take-up effect.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-6A tension-controllable take-up device for ultrafine fibers includes a base 1, on which a first bracket 2 and a second bracket 3 are mounted. Mounting plates 4 are rotatably connected to both sides of the first bracket 2, and a take-up roller 5 is mounted between the two mounting plates 4. A drive motor 6 is also mounted on the first bracket 2. One end of the output shaft of the drive motor 6 is connected to one side of the mounting plate 4. When the drive motor 6 is started, its output shaft drives the mounting plate 4 to rotate, which in turn drives the take-up roller 5 mounted between the two mounting plates 4 to rotate. The take-up roller 5 has an insertion groove 7 inside, which allows fiber to be inserted into the roller. The end of the fiber fabric passes through it. A clamping assembly is also provided on the take-up roller 5. This clamping assembly can fix and press the fiber fabric passing through the insertion groove 7, thus fixing the end of the fiber fabric to the take-up roller 5 under pressure. When the take-up roller 5 rotates, it can wind up the fiber fabric. A set of support rollers 8 is rotatably connected to the inner wall of the second bracket 3. A first electric telescopic rod 9 is installed at the top of the second bracket 3. One end of the output shaft of the first electric telescopic rod 9 is connected to a first connecting frame 10. A pressure roller 11 is rotatably connected to the first connecting frame 10, and the pressure roller 11 is located below the support rollers. Above the support roller 8, the output shaft of the first electric telescopic rod 9 can drive the pressure roller 11 to move up and down. When the take-up roller 5 takes up the fiber fabric, the fiber fabric can pass between the support roller 8 and the pressure roller 11. By controlling the output shaft of the first electric telescopic rod 9 to drive the pressure roller 11 to move downward, the fiber fabric can be pressed against the surface of the support roller 8. At this time, the fabric will be in close contact with the surface of the support roller 8. A transmission component is provided between one side of the support roller 8 and one side of the mounting plate 4. When the take-up roller 5 and the mounting plate 4 rotate, the transmission component can drive the support roller 8 to rotate synchronously. A second electric telescopic rod 12 is installed at the top between the first bracket 2 and the second bracket 3. One end of the output shaft of the second electric telescopic rod 12 is fixedly connected to a second connecting frame 13. A lifting roller 14 is rotatably mounted on the second connecting frame 13. The output shaft of the second electric telescopic rod 12 can drive the second connecting frame 13 to move up and down. When the second connecting frame 13 is controlled to drive the lifting roller 14 to move downward, the lifting roller 14 can press the fiber fabric located between the take-up roller 5 and the support roller 8 downward, so that the fabric will be subjected to a certain tension under the pressing action of the lifting roller 14 before it is wound onto the take-up roller 5.

[0024] During use, the device is first placed next to the outlet of the fiber fabric machine. When the fabric extends from the outlet, it can pass between the support roller 8 and the pressure roller 11. Then, the end of the fabric is passed through the insertion groove 7 inside the take-up roller 5 and pressed and fixed onto the take-up roller 5 by the pressure assembly. At this time, the pressure roller 11 can be controlled to move downward so that the fabric can make close contact with the surface of the support roller 8. Under the action of frictional resistance between the fabric and the surface of the support roller 8, the fabric can slide relative to the support roller 8. When the drive motor 6 is started to drive the take-up roller 5 to rotate, the take-up roller 5 can take up the fabric. At the same time, the support roller 8 can rotate synchronously with the take-up roller 5 under the action of the transmission assembly, so that the fabric is taken up. During the process, the length of the fabric section between the take-up roller 5 and the support roller 8 can be kept fixed. At this time, the lifting roller 14 is controlled to move downward by the second electric telescopic rod 12. When the lifting roller 14 contacts the fabric between the take-up roller 5 and the support roller 8, it can generate downward tension on the fabric. By adjusting the height of the lifting roller 14, the tension on the fabric can be adjusted. Therefore, the user can flexibly adjust the tension on the fabric when it is wound onto the take-up roller 5 according to the material and thickness of the fabric, so that the fabric can be kept taut before being wound onto the take-up roller 5, so that the fabric will not wrinkle on the take-up roller 5 due to looseness, and also avoid the fabric from being damaged under large tension.

[0025] For further details, please refer to Figure 1-6 The transmission assembly includes a first pulley 15 fixedly connected to one side of the mounting plate 4, a second pulley 16 fixedly connected to one side of the support roller 8, and a transmission belt 17 sleeved between the first pulley 15 and the second pulley 16. During the rotation of the mounting plate 4 and the take-up roller 5, the first pulley 15 will be driven to rotate. At this time, the second pulley 16 will be driven to rotate synchronously through the transmission action of the transmission belt 17. Therefore, the support roller 8 can maintain synchronous rotation with the take-up roller 5 under the driving action of the second pulley 16.

[0026] For further details, please refer to Figure 1-6The clamping assembly includes a slide groove 18 disposed on the take-up roller 5 and connected to the insertion groove 7, and a pressure block 19 disposed inside the slide groove 18. The pressure block 19 can slide inside the slide groove 18. Mounting holes 20 are provided on both sides of the pressure block 19. Threaded holes 21 corresponding to the mounting holes 20 are also provided on both sides of the insertion groove 7. When the fiber fabric passes through the insertion groove 7, the pressure block 19 can be pressed into the slide groove 18. At this time, the pressure block 19 will extend into the insertion groove 7 and press on the fiber fabric. By using screws to pass through the mounting holes 20 and screw them into the threaded holes 21, the pressure block 19 extending into the insertion groove 7 can be fixed. Under the pressing action of the pressure block 19, the end of the fabric passing through the insertion groove 7 cannot fall out of the insertion groove 7, thereby achieving a fixed connection between the end of the fabric and the take-up roller 5.

[0027] For further details, please refer to Figure 1-6 Several sets of bolt holes 22 are provided between the mounting plate 4 and the two sides of the take-up roller 5, and the positions of the bolt holes 22 between the mounting plate 4 and the take-up roller 5 correspond to each other. When the take-up roller 5 is placed between the two sets of mounting plates 4, the take-up roller 5 can be fixedly connected between the two sets of mounting plates 4 by passing bolts through the corresponding bolt holes 22 and tightening nuts on the ends of the bolts. The take-up roller 5 can be separated from the two sets of mounting plates 4 by removing the bolts passing through the bolt holes 22. After the take-up roller 5 has finished winding the fabric, the take-up roller 5 can be removed from the two sets of first brackets 2.

[0028] For further details, please refer to Figure 1-6 A scale bar 23 is provided on one side of the base 1, and a pointer 24 for pointing to the scale bar 23 is provided on one side of the second connecting frame 13. When the user controls the lifting height of the lifting roller 14 to adjust the tension generated on the fabric, the height position of the lifting roller 14 can be accurately understood by observing the reading of the scale bar 23 pointed to by the pointer 24, which facilitates more precise adjustment of the tension generated on the fabric.

[0029] For further details, please refer to Figure 1-6 The surface of the support roller 8 is provided with a textured surface. When the pressure roller 11 moves downward to press the fabric onto the surface of the support roller 8, the textured surface of the support roller 8 can ensure that there is a large frictional resistance between the fabric and the support roller 8, thus preventing relative sliding between the fabric and the support roller 8 during the winding process. This ensures that the length of the fabric between the winding roller 5 and the support roller 8 can remain fixed, thereby ensuring that the lifting roller 14 can exert a stable tension on the fabric located between the winding roller 5 and the support roller 8.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
