Description

Technical Field

[0001] This utility model relates to the field of silk felt production technology, specifically to a guide tensioning device for pre-oxidized silk felt production. Background Technology

[0002] In the production process of pre-oxidized fiber felt, the pre-oxidized fiber needs to undergo multiple processes and equipment treatments. During this process, the guidance and tension of the pre-oxidized fiber have a crucial impact on the quality of the final felt product.

[0003] Currently, the existing guiding devices used in pre-oxidized fiber felt making have a relatively simple structure, consisting of multiple guide wheels. Although this type of guiding device can guide the direction of the pre-oxidized fiber, it may break the pre-oxidized fiber when the tension is too high during the pre-oxidized fiber felt making process. If the tension is too low, the pre-oxidized fiber will slack off, affecting the density and strength of the felt. The existing guiding device only has a guiding function and cannot adjust the tension of the pre-oxidized fiber, which is inconvenient to use. Utility Model Content

[0004] This invention provides a guiding and tensioning device for pre-oxidized fiber felt making to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A guiding and tensioning device for pre-oxidized fiber felt production includes a fixing mechanism, a guiding mechanism fixedly connected to one side of the fixing mechanism, a tension adjustment mechanism provided on the surface of the guiding mechanism, a mounting component, a telescopic rod inserted into the mounting component, a guide rail fixedly connected to one end of the telescopic rod, a driving block fixedly connected to the surface of the telescopic rod, a driving plate engaging the surface of the driving block, a rotating shaft fixedly connected to one side of the driving plate, a take-up reel fixedly connected to one end of the rotating shaft, a pull wire overlapping the surface of the take-up reel, a snap-fit ​​block fixedly connected to one end of the pull wire, a rotating shaft rotatably connected to the interior of the mounting component, and pre-oxidized fiber overlapping the interior of the guide rail.

[0007] A further improvement of the present invention is that the fixing mechanism includes a fixing frame, and mounting ears are fixedly connected to the surface of the fixing frame.

[0008] A further improvement of this utility model is that a fixing rod is fixedly connected to one side of the fixing frame, and one end of the fixing rod is fixedly connected to one side of the mounting component.

[0009] A further improvement of the present invention is that the tension adjustment mechanism includes a sliding groove, one side of which is fixedly connected to one side of the mounting component, and a force-applying component is provided inside the sliding groove.

[0010] A further improvement of the present invention is that the force-applying component includes a sleeve cap, the inside of which is sleeved with the top of the sliding groove.

[0011] A further improvement of this utility model is that: the surface of the sleeve cap is threaded with a fixing screw, and one end of the fixing screw is threadedly connected to the inside of the sliding groove.

[0012] A further improvement of this utility model is that a spring is fixedly connected to the top of the inner cavity of the sleeve cap, and a sliding block is fixedly connected to one end of the spring.

[0013] A further improvement of this utility model is that: the surface of the sliding block is slidably connected to the inner wall of the sliding groove, and a snap-fit ​​component is fixedly connected to one side of the sliding block, with the inner wall of the snap-fit ​​component overlapping the surface of the snap-fit ​​block.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a guiding and tensioning device for pre-oxidized fiber felt making. Through the setting of a guiding mechanism and a tension adjustment mechanism, during the process of guiding the pre-oxidized fiber via the guide rail, when the pre-oxidized fiber tension is too high (exceeding the spring force), the pre-oxidized fiber tension pushes the telescopic rod into the mounting part, reducing the diameter of the guiding mechanism and thus reducing the pre-oxidized fiber tension. When the pre-oxidized fiber tension is low (less than the spring force), the pre-oxidized fiber tension is pulled and elongated, causing the take-up wheel to drive the rotating shaft to rotate. This causes the drive plate to push the drive block outward, allowing the telescopic rod to extend out of the mounting part, increasing the diameter of the guiding mechanism and thus increasing the pre-oxidized fiber tension. This allows for automatic adjustment of the pre-oxidized fiber tension and is more convenient to use compared to conventional guiding devices. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-6 As shown, this utility model provides a guiding tensioning device for pre-oxidized fiber felt making, including a fixing mechanism, a guiding mechanism fixedly connected to one side of the fixing mechanism, a tension adjustment mechanism provided on the surface of the guiding mechanism, the guiding mechanism including a mounting part 21, a telescopic rod 22 inserted into the mounting part 21, a guide rail 23 fixedly connected to one end of the telescopic rod 22, a driving block 24 fixedly connected to the surface of the telescopic rod 22, a driving plate 25 engaged on the surface of the driving block 24, a rotating shaft 26 fixedly connected to one side of the driving plate 25, a take-up reel 27 fixedly connected to one end of the rotating shaft 26, a pull wire 28 overlapping the surface of the take-up reel 27, a snap-fit ​​block 29 fixedly connected to one end of the pull wire 28, the surface of the rotating shaft 26 rotatably connected to the interior of the mounting part 21, and pre-oxidized fiber 210 overlapping the interior of the guide rail 23.

[0026] In this embodiment, during the pre-oxidized fiber felt-making process, the pre-oxidized fiber 210 is guided by the groove on the surface of the guide rail 23. During the guiding process, when the tension of the pre-oxidized fiber 210 is greater than the pulling force of the spring 323, the guide rail 23 pushes the telescopic rod 22 to move into the mounting component 21 under the action of the tension of the pre-oxidized fiber 210, thereby reducing the overall diameter of the guiding mechanism, reducing the required length of the pre-oxidized fiber 210 winding on the surface of the guiding mechanism, and further reducing the tension of the pre-oxidized fiber 210 to avoid breakage due to excessive tension.

[0027] Example 2

[0028] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the fixing mechanism includes a fixing frame 11, the surface of the fixing frame 11 is fixedly connected to a mounting ear 12, one side of the fixing frame 11 is fixedly connected to a fixing rod 13, one end of the fixing rod 13 is fixedly connected to one side of the mounting component 21, the tightness adjustment mechanism includes a sliding groove 31, one side of the sliding groove 31 is fixedly connected to one side of the mounting component 21, and a force-applying component 32 is provided inside the sliding groove 31.

[0029] In this embodiment, when the tension of the pre-oxidized wire 210 is too low, it is less than the tension of the spring 323. Under the action of the spring 323, the sliding block 324 is pulled to slide along the inner wall of the sliding groove 31, thereby causing the snap-fit ​​piece 325 to pull the snap-fit ​​piece 29 upward, which in turn stretches the wire 28. This causes the take-up wheel 27 to drive the rotating shaft 26 to rotate. Under the action of the rotating shaft 26, the groove on the surface of the drive plate 25 pushes the drive block 24 to move outward, thereby causing the drive block 24 to drive the telescopic rod 22 to extend out of the mounting piece 21, expanding the overall diameter of the guide mechanism, increasing the required length of the pre-oxidized wire 210 winding on the surface of the guide mechanism, and thus increasing the tension of the pre-oxidized wire 210, so that the tension of the pre-oxidized wire 210 can be automatically adjusted.

[0030] Example 3

[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the force-applying component 32 includes a sleeve cap 321, the inside of the sleeve cap 321 is sleeved with the top of the sliding groove 31, the surface of the sleeve cap 321 is threaded with a fixing screw 322, one end of the fixing screw 322 is threaded with the inside of the sliding groove 31, the top of the inner cavity of the sleeve cap 321 is fixedly connected with a spring 323, one end of the spring 323 is fixedly connected with a sliding block 324, the surface of the sliding block 324 is slidably connected with the inner wall of the sliding groove 31, one side of the sliding block 324 is fixedly connected with a snap-fit ​​component 325, and the inner wall of the snap-fit ​​component 325 overlaps with the surface of the snap-fit ​​block 29.

[0032] In this embodiment, by simultaneously removing the fixing screw 322, the snap-fit ​​block 29 can be removed from the surface of the snap-fit ​​part 325, and the force-applying part 32 with different spring tensions can be replaced. This changes the adjustable tension of the device, thereby adapting to different process requirements and making it easier to use.

[0033] The working principle of the guiding and tensioning device for pre-oxidized fiber felt making will be explained in detail below.

[0034] like Figure 1-6As shown, during the pre-oxidized fiber felt-making process, the pre-oxidized fiber 210 is guided by the groove on the surface of the guide rail 23. During the guiding process, when the tension of the pre-oxidized fiber 210 is greater than the tension of the spring 323, the guide rail 23 pushes the telescopic rod 22 into the mounting part 21 under the action of the tension of the pre-oxidized fiber 210, thereby reducing the overall diameter of the guiding mechanism, reducing the required length of the pre-oxidized fiber 210 winding on the surface of the guiding mechanism, and further reducing the tension of the pre-oxidized fiber 210 to avoid breakage due to excessive tension. When the tension of the pre-oxidized fiber 210 is too small, the tension is less than the tension of the spring 323. Under the action of the tension of the spring 323, the sliding block 324 is pulled to slide along the inner wall of the sliding groove 31, thereby causing the snap-fit ​​part 325 to pull the snap-fit ​​block 29 upward. The tension wire 28 is then stretched, causing the take-up reel 27 to drive the rotating shaft 26 to rotate. Under the action of the rotating shaft 26, the groove on the surface of the drive plate 25 pushes the drive block 24 outward, thereby causing the drive block 24 to drive the telescopic rod 22 to extend out of the mounting part 21, expanding the overall diameter of the guide mechanism, increasing the required length of the pre-oxidized wire 210 winding on the surface of the guide mechanism, and thus increasing the tension of the pre-oxidized wire 210. This allows the tension of the pre-oxidized wire 210 to be automatically adjusted, making it easier to use. At the same time, after removing the fixing screw 322, the snap-fit ​​block 29 can be removed from the surface of the snap-fit ​​part 325, and the force-applying part 32 with different spring tensions can be replaced. This changes the adjustable tension of the device, thereby adapting to different process requirements and making it easier to use.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
