Description

Technical Field

[0001] This invention relates to the field of electronic-grade glass fiber cloth technology, and in particular to a warping machine for electronic-grade glass fiber yarn. Background Technology

[0002] Electronic fiberglass cloth is woven from electronic-grade fiberglass yarn, then undergoes desizing, firing, and treatment processes to form the finished electronic-grade fiberglass cloth. Fiberglass cloth is mainly used in ship hulls, storage tanks, cooling towers, ships, vehicles, tank trucks, and building structural materials. Industrially, fiberglass cloth is primarily used for heat insulation, fireproofing, and flame retardancy. When exposed to flame, this material absorbs a large amount of heat and prevents flames from passing through, thus isolating the air.

[0003] Currently, the fiberglass industry has a high demand for new types of electronic fabrics. The sizing stage is the source of electronic fabrics; only by properly sizing the yarn can high-quality electronic fabrics be produced. However, existing warping machines use three or four feeder frames, which can only produce common specifications such as 732 / 742 / 552 / 559 / 502 / 202 / 102 warp yarns with diameters between 5-8 micrometers and a warp head count between 2200-3200. In contrast, sizing machines have 700-800 tensioners and a yarn count between 700-800. With only three or four feeder frames, it is impossible to produce ultrafine yarns and higher specification warp yarns. Therefore, it is impossible to produce higher-end ultrafine thin electronic fabric products.

[0004] In view of the above reasons, the present invention proposes a warping machine for electronic-grade glass fiber yarn, which can produce warp yarns of higher specifications, thereby being used to manufacture ultra-thin electronic fabric products. Summary of the Invention

[0005] The purpose of this invention is to provide a warping machine for electronic-grade glass fiber yarn, which can produce warp yarns of higher specifications for use in manufacturing ultra-thin electronic fabric products.

[0006] This invention provides a warping machine for electronic-grade glass fiber yarn, comprising: at least five sending beam devices of different heights, a yarn separating device, and a take-up device. Each sending beam device includes a warp beam, a sending motor, a reducer, a small sending roller, a large sending roller, and a sending cylinder. The warp beam rotates under the drive of the sending motor and the reducer. The warp yarn is drawn out from the warp beam, passes around the small and large sending rollers, and is fed out at a set tension under the control of the sending cylinder. The yarn separating device includes a lower layering support, an upper layering support, a layering reed, and a reed support. The warp yarn emitted from the sending beam device is introduced through the lower or upper layering support, and after being layered by the layering reed, is fed to the take-up device according to a set width. The take-up device includes a take-up roller, a pressing roller, a tension roller, and a warp beam. The layered warp yarn is pressed down by the pressing roller and then passes around the take-up roller, and is wound on the warp beam under the stable tension provided by the tension roller.

[0007] Preferably, a tension sensor is provided on one side of the sending roller.

[0008] Preferably, the system also includes a control computer, wherein each of the tension sensors transmits the measured tension data to the control computer for display, and the control computer controls the acceleration and deceleration of the sending motor and the reducer based on the difference between the tension data and the preset tension.

[0009] Preferably, the sending cylinder is equipped with a pressure proportional valve, and the tension fluctuation correction value of one or all of the sending shaft devices can be manually adjusted by the value displayed by the pressure proportional valve, so that the tension is controlled within the fluctuation range of 5%.

[0010] Preferably, a displacement sensor is also provided at the bottom of the sending roller.

[0011] Preferably, the number of the sending shaft frame devices is six.

[0012] Preferably, the height of each of the sending shaft frame devices increases from the side away from the yarn separating device to the side closer to it, and the height increase of adjacent sending shaft frame devices is 3cm to 5cm.

[0013] Preferably, the upper layer support and the lower layer reed are mounted on the reed support, the reed density of the lower layer reed is 2.5mm to 3mm, and both the reed support and the lower layer support are disposed on the yarn separating platform.

[0014] Preferably, a pressing cylinder and a pressing wheel are provided on one side of the weaving beam. The pressing cylinder is used to control the height of the pressing wheel so that the pressing wheel presses the top of the weaving beam.

[0015] Preferably, the bottom of the warp beam is further provided with a support arm cylinder and a support arm, the clamp of the warp beam is placed on the support arm, and the height of the support arm can be adjusted under the action of the support arm cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention, by increasing the number of sending shaft frame devices, can achieve five-axis or six-axis parallel operation, thereby reducing the number of warp yarns on a single warp beam, reducing warp density, significantly improving sizing efficiency, solving the problem of warp yarn breakage during sizing, and also increasing the number of warp yarn ends on the warp beam. The number of warp yarn ends on the warp beam can be increased to a maximum of 2200-5000, exceeding the level of the same industry, and can be used to produce a variety of higher-specification fine yarns or ultrafine yarns, and thus for the production of ultrafine thin electronic cloth products;

[0018] 2. Each sending beam device of the present invention can provide stable tension for the warp yarn and can detect tension fluctuations, reduce tension fluctuations, ensure efficient production of microfiber yarn, and ensure smooth warp yarn tension when the microfiber yarn beam is wound up, thereby improving the quality of microfiber yarn.

[0019] 3. In this invention, the heights of the various sending shafts are different, and the sent warp yarns run on separate layer paths, effectively preventing the warp yarn ends from rubbing together and causing yarn breakage. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] like Figure 1-3As shown, the present invention provides a warping machine for electronic-grade glass fiber yarn, comprising: at least five sending beam frame devices 101 of different heights, a yarn separating device 102, and a take-up device 103. The sending beam frame device 101 includes a warp beam 3, a sending motor 6, a reducer 7, a small sending roller 4, a large sending roller 2, and a sending cylinder 5. The warp beam 3 rotates under the drive of the sending motor 6 and the reducer 7, drawing out the warp yarn wound on it and passing it around the small sending roller 4 and the large sending roller 2. The small sending roller 4 and the large sending roller 2 are controlled by the sending cylinder to deliver the warp yarn at a set tension. The yarn separating device 102 includes a lower layer support 9, an upper layer support 10, a layer reed 11, and a reed support 12. The lower layer support 9 and the upper layer support 10 are provided with multiple evenly arranged guide rollers. The warp yarns emitted by the sending shaft holder device 101 are introduced through the lower layer support 9 or the upper layer support 10. The reeds 11 have the same reed density, so that the warp yarns emitted by multiple sending shaft holder devices 101 are uniformly layered under the action of the layer reeds 11. After layering, they are sent to the take-up device 103 according to the set width. The take-up device 103 includes a take-up roller 16, a pressing roller 17, a tension roller 19 and a warp beam 21. The pressing roller 17 is located on top of the take-up roller 16 and is arranged close to and tangential to it. The warp yarns pass through the gap between the two. The tension roller is located on one side of the take-up roller 16. The warp beam 21 is located below the take-up roller 16. After being pressed down by the pressing roller 17, the layered warp yarns are wound around the take-up roller 16 and wound on the warp beam 21 with a specific width under the stable tension provided by the tension roller 19.

[0030] In this embodiment, a tension sensor 23 is provided on one side of the sending roller 4. The tension sensor 23 can sense the tension of the warp yarn. The warping machine also includes a control computer 18. Each tension sensor 23 transmits the measured tension data to the control computer 18 for display on the sending tension display page. The control computer 18 can detect the tension fluctuation of each sending roller 101 at any time. Based on the difference between the tension data and the preset tension, the control computer 18 controls the sending motor 6 and the reducer 7 to accelerate or decelerate, thereby adjusting the tension of the warp yarn.

[0031] In this embodiment, a pressure proportional valve can be installed on the air intake pipe of the sending cylinder 5 according to the tension fluctuation. The value displayed by the pressure proportional valve can be manually adjusted to adjust the tension fluctuation correction value of a single or all sending shaft bracket devices 101, so that the tension is controlled within the fluctuation range of 5%.

[0032] In this embodiment, a displacement sensor 24 is also provided at the bottom of the large sending roller 2. The displacement sensor 24 can detect the displacement of the warp yarn, and can detect the yarn breakage phenomenon in time.

[0033] In this embodiment, there are six warp beam sending devices 101. By increasing the number of sending beam sending devices 101, the number of warp beam heads of a certain specification is 3000. With six warp beams combined, 3000 / 6 = 500 warp beam heads, the warp density is reduced when the sizing machine produces 500 warp beam heads, resulting in a significant sizing effect. The sizing LOI is 5.8%, solving the problem of warp yarn breakage during sizing, with a defect rate of only 0.10%. The height of each sending beam sending device 101 increases from the side furthest from the yarn separating device 102 to the side closest to it. The increase in height between adjacent sending beam sending devices 101 is 3cm to 5cm. This method ensures that the warp yarns sent out by each sending beam sending device 101 run along a separate layer path, effectively preventing warp yarn heads from rubbing together and causing breakage.

[0034] In this embodiment, the upper layer support 10 and the layer reed 11 are installed on the reed support 12. The layer reed 11 is detachably installed on the reed support 12 by fixing screws 13. The reed density of the layer reed 11 is 2.5mm to 3mm. The reed support 12 and the lower layer support 9 are both set on the yarn separating platform 8.

[0035] In this embodiment, a yarn pressing cylinder 15 is provided on one side of the weaving shaft 21. The top of the yarn pressing cylinder 15 is provided with a yarn pressing wheel that is rotatably connected to it. The yarn pressing cylinder 15 is used to control the height of the yarn pressing wheel so that the yarn pressing wheel presses on the top of the weaving shaft 21 and can be finely rotated as the warp yarn is wound up.

[0036] In this embodiment, the bottom of the warp beam 21 is also provided with a support arm cylinder 20 and a support arm 22. One end of the support arm cylinder 20 is rotatably connected to the support arm 22, and the other end can slide and adjust along the arc-shaped slide. The clamp of the warp beam 21 is placed on the support arm 22, so that the height of the support arm 22 can be adjusted by the movement of the support arm cylinder 20. A step stool 14 is also provided on one side of the warp beam 21, which allows workers to easily climb up to inspect the working condition of the warp beam 21 and other structures.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
