Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass rotating body winding machinery technology, and in particular to an adjustable yarn sheet wide yarn separating device. Background Technology
[0002] Yarn separating devices are key equipment (components) used in industries such as composite materials, textiles, chemical fibers, and nonwoven fabrics to separate, comb, or guide yarns. Their core function is to separate, arrange, or combine multiple yarns or fiber bundles according to specific requirements to ensure the smooth progress of subsequent processing (such as winding, braiding, weaving, needle punching, hydroentangling, etc.). Therefore, their performance directly determines the efficiency of subsequent processes and product quality.
[0003] However, traditional yarn splitting devices generally suffer from technical defects such as lack of adjustment function or limited adjustment range. Specifically, existing technologies mostly adopt rigid structural designs, such as fixed yarn guides, yarn splitting plates with preset angles, or non-adjustable pneumatic nozzles. This results in the yarn splitting path, yarn spacing, and tension control parameters being fixed during the equipment manufacturing stage. As a result, if it is necessary to adapt to yarns with different linear densities, elastic moduli, or surface properties (such as glass fiber and carbon fiber winding processes) during the production process, the entire yarn splitting assembly must be manually disassembled and replaced to adjust the parameters. This is not only time-consuming and labor-intensive, and the adjustment accuracy is difficult to guarantee, but also leads to a significant decrease in production efficiency due to downtime for modification.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of this utility model.
[0030] Reference Figure 1-4An adjustable yarn width separating device, through ingenious structural design, can quickly adjust the yarn width online according to diverse production needs, ensuring orderly yarn separation and smooth entry into subsequent processing steps, thereby improving production efficiency and product quality. Specifically...
[0031] The device includes a yarn separating comb fixing plate 3, which serves as the basic support structure for the entire device and provides a stable platform for the installation of other components. Preferably, the yarn separating comb fixing plate 3 is rectangular in shape, which gives the fixing plate sufficient strength and stability to withstand various forces generated during the yarn separating process and ensure that the device will not shake or deform during operation.
[0032] A yarn separating comb bracket I1 and a yarn separating comb bracket II2 are installed on the yarn separating comb fixing plate 3. The yarn separating comb bracket I1 and the yarn separating comb bracket II2 are used as core adjustment components to cooperate with each other to facilitate yarn separating operation. Both the yarn separating comb bracket I1 and the yarn separating comb bracket II2 include a bracket body, one end of which is hinged to the yarn separating comb fixing plate 3. This not only achieves installation but also facilitates relative rotation between the bracket body and the yarn separating comb fixing plate 3 for adjustment as needed, thus better realizing the yarn separating operation. Preferably, one end of the bracket body of the yarn separating comb bracket I1 and the yarn separating comb bracket II2 is hinged to the yarn separating comb fixing plate 3 through the same hinge shaft, and is arranged in a V-shape on the yarn separating comb fixing plate 3. This not only optimizes the spatial structure, allowing the yarn to separate more smoothly when passing through the yarn separating area, reducing friction and tangling between the yarns, but also provides convenience for subsequent adjustment operations. By adjusting the included angle between the two bracket bodies, the width of the yarn sheet can be easily changed to adapt to the production needs of different specifications and types of yarn.
[0033] To facilitate the adjustment and fixation of the support body, an adjusting bolt 8 is screwed onto the other end of the support body. An adjusting groove 10 that cooperates with the adjusting bolt 8 is provided on the yarn comb fixing plate 3. When the support body is adjusted, the adjusting bolt 8 always moves along the adjusting groove 10. The position of the support body can be adjusted by manually tightening or loosening the adjusting bolt 8.
[0034] Preferably, the adjusting bolt 8 is a hexagonal bolt, which has high strength and stability and can withstand large adjustment forces, ensuring that it will not loosen or be damaged during adjustment. A wing nut 7 is also installed on the hexagonal bolt for easy operation. The operator can easily tighten or loosen the adjusting bolt 8 by simply rotating the wing nut 7 without using special tools. The adjusting groove 10 is an arc-shaped groove that matches the rotation trajectory of the bracket body, allowing the adjusting bolt 8 to move smoothly within the arc-shaped groove, further improving the flexibility and accuracy of adjustment.
[0035] Several combs 5 are rotatably mounted on the top of the support body for separating the yarn. Specifically, the combs 5 are arranged perpendicular to the support body and are evenly spaced in a linear arrangement. A separation gap is left between two adjacent combs 5 to cooperate with the yarn, ensuring that each yarn can pass through the separation gap evenly. This avoids uneven yarn separation caused by uneven yarn distribution and effectively improves the quality and stability of yarn separation. Preferably, 10-15 combs 5 are provided on each support body.
[0036] Preferably, the comb 5 is rotatably mounted on the support body via a shaft retaining ring 6 and a deep groove bearing 4. The deep groove bearing 4 has advantages such as low coefficient of friction, smooth operation, and long service life, ensuring that the comb 5 can rotate freely under the friction of the yarn, reducing the friction between the yarn and the comb 5, and lowering the risk of yarn wear and breakage. The shaft retaining ring 6 serves as an axial positioning element, preventing the deep groove bearing 4 from moving axially during operation, thus ensuring the stability and reliability of the comb 5 installation.
[0037] Preferably, a pressure plate 9 for limiting the deep groove bearing 4 is also installed on the bracket body. The pressure plate 9 is connected to the bracket body on one side of the deep groove bearing 4 by bolts. The pressure plate 9 can effectively prevent the deep groove bearing 4 from moving when subjected to external force, ensuring that the comb 5 always stays in the correct position, thereby ensuring the accuracy and stability of yarn separation.
[0038] In actual use, the yarn comb 5 is cylindrical in shape, which makes the contact area between the yarn comb 5 and the yarn uniform and can better guide the yarn through the yarn separation gap. The top of the yarn comb 5 is hemispherical, which can reduce the friction and collision between the yarn and the top of the yarn comb 5, avoid damage to the yarn when passing through the yarn comb 5, and play a certain protective role for the yarn.
[0039] In actual production, operators can adjust the position of the adjusting bolt 8 in the arc-shaped adjusting groove 10 by rotating the wing nut 7 according to different production needs, thereby changing the included angle between the yarn separating comb bracket I and the yarn separating comb bracket II, and realizing online rapid adjustment of the yarn separating width. At the same time, since the yarn comb 5 is rotatably mounted on the bracket body through the deep groove bearing 4 and the shaft retaining ring 6, and is limited by the pressure plate 9, the yarn comb 5 can rotate freely and maintain a stable position when the yarn passes through the separating gap, ensuring that the yarn can be separated smoothly. The specific operation process is as follows:
[0040] 1. Securely install the yarn separating comb fixing plate 3 in the designated position on the textile or chemical fiber production equipment, ensuring that the connection between the fixing plate and the equipment is firm and there is no shaking.
[0041] 2. Introduce the yarn to be separated from the front end of the production equipment and slowly pass each yarn through the separation gap between adjacent combs 5.
[0042] 3. After the yarn is introduced and normal operation begins, the operator should closely observe the yarn separation process;
[0043] 4. If the yarn separation is found to be unsatisfactory during production, such as an unsuitable separation angle causing yarn tangling or uneven separation gap affecting yarn quality, the operator can make timely online adjustments. There is no need to stop the production equipment. Simply rotate the wing nut 7 on the yarn separating comb bracket that needs adjustment manually and loosen the adjusting bolt 8. Depending on the actual situation, slowly rotate the bracket body to change the angle between it and the yarn separating comb fixing plate 3, thereby adjusting the yarn separation width. After adjusting to the appropriate position, tighten the wing nut 7 again to fix the position of the bracket body.
[0044] 5. After completing the adjustment, continue to observe the yarn separation to confirm the adjustment effect. If the yarn separation effect meets the production requirements, allow the production equipment to continue operating normally; otherwise, adjust again.
[0045] The advantages of the adjustable yarn width separating device provided in this application are:
[0046] 1. The function of online quick adjustment of yarn width allows operators to adjust the yarn splitting parameters in a timely manner according to actual production needs without stopping the machine, which greatly saves adjustment time and labor costs and improves production efficiency.
[0047] 2. Precise yarn separation width adjustment and stable comb installation structure ensure that the yarn can be separated evenly and smoothly, effectively reducing the occurrence of yarn breakage, tangling and other problems, and improving product quality;
[0048] 3. The device has a reasonable structural design and the components are closely matched, which gives it high reliability and stability and makes it suitable for long-term, high-intensity production operations.
