[0002] Sound-absorbing cloth, also known as speaker cloth or acoustically transparent cloth, is commonly used in microphones, audio equipment, and other devices to protect speaker units, prevent dust from entering, and modify the sound to a certain extent, thereby improving the performance and lifespan of the audio equipment. During the production process of sound-absorbing cloth, the yarn can easily be carried into the shuttle opener, causing weft breakage and affecting the production of the mesh fabric. Therefore, anti-weft breakage devices are needed to ensure the normal production of the mesh fabric.

However, it is difficult to reduce the frictional changes experienced by the weft yarn during implementation, and the fibers attached to the weft yarn tend to accumulate in the weft bobbin, causing path blockage and further increasing the risk of weft yarn breakage. Therefore, we provide a mesh fabric anti-weft breakage device to solve the above problems. Utility Model Content

[0024] This utility model provides a device for preventing weft breakage in mesh fabric.

[0025] Please see Figure 1 , Figure 3 and Figure 4 The device includes a weft breakage prevention bracket 1, which can be installed on the loom to provide support for the use of the device. This allows the device to reduce the risk of breakage during the weft weaving process and prevent frequent loom shutdowns caused by weft breakage, thereby reducing production efficiency. The structural components shown in the accompanying drawings of this application are all illustrative examples. The specific implementation should be adapted and optimized based on the functional requirements, assembly conditions and process limitations in the actual application scenario, including structural parameters, size specifications and connection methods.

[0026] Please see Figure 1 and Figure 2 The anti-weft breakage bracket 1 has an internally fixed connection to an installation rod 2. A set of fixing rings 3 are fixedly connected to the outer surface of the installation rod 2. Each fixing ring 3 has a guide ceramic head 4 on its outside. The installation rod 2 provides support for the installation of the fixing rings 3 and the guide ceramic head 4. The fixing rings 3 provide support for the installation of the guide ceramic head 4. The guide ceramic head 4 is a guide support point for the yarn, ensuring that the yarn is transported along a predetermined path. The guide ceramic head 4 is made of zirconia ceramic material. The yarn inlet is designed with a 60° flared opening, and the outlet is designed with a 15° tapering angle. The surface of the guide ceramic head 4 is relatively smooth, which can effectively reduce the friction force encountered by the weft yarn when it passes through, making the weft yarn smoother during the transport process, reducing the tension changes caused by friction, and thus reducing the occurrence of weft breakage.

[0027] Multiple miniature springs 5 ​​are provided between the fixing ring 3 and the guide ceramic head 4. The two ends of each miniature spring 5 are fixedly connected to the fixing ring 3 and the guide ceramic head 4 respectively. The miniature springs 5 ​​are used to support the use of the guide ceramic head 4. By setting multiple miniature springs 5, when the yarn passes through the guide ceramic head 4, the guide ceramic head 4 can adjust its angle to a certain extent according to the stress change of the yarn, thereby absorbing part of the tension peak of the yarn, effectively reducing the risk of yarn breakage due to excessive tension, and improving the quality and efficiency of mesh weaving.

[0028] Please see Figure 1 , Figure 3 and Figure 4 A set of fans 7 are fixedly installed on the top surface of the anti-weft breakage bracket 1. Each fan 7 has an output shaft rotatably installed inside. When the fan 7 is started, it can generate a certain suction force, which can suck the fiber fabric attached to the surface of the yarn in the guide ceramic head 4 towards the fan 7. The operating frequency of the fan 7 is set to be low. Because the yarn fiber is light, even if the fan 7 runs at a low frequency, it can still suck the fiber out of the guide ceramic head 4, thereby avoiding the accumulation of fiber in the guide ceramic head 4 and causing blockage of the guide ceramic head 4, and ensuring the normal passage of the yarn.

[0029] Each output shaft is fixedly connected to a transmission rod 8 at its end. Each transmission rod 8 is fixedly connected to a corresponding connecting rod 608. When the fan 7 is running, the output shaft inside rotates, which drives the fan blades to rotate, thereby generating airflow to adsorb fibers. The rotation of the output shaft can drive the transmission rod 8 to rotate, thereby providing power for the rotation of the subsequent connecting rod 608, providing power for the self-cleaning operation of the device, and simplifying the power structure of the device.

[0030] Please see Figure 3 and Figure 4 Each guide ceramic head 4 is equipped with a recycling mechanism 6 above it. The recycling mechanism 6 includes a ventilation hole 601 inside the anti-weft breakage bracket 1. Through the setting of the recycling mechanism 6, the operation of the fan 7 can realize the self-cleaning of the fiber by the device, avoid the fiber fabric attached to the weft thread from clogging the guide tube, reduce the probability of weft thread breakage, reduce the frequent shutdown of the loom due to weft breakage, improve the production efficiency of the loom, prevent the fabric from being defective due to weft breakage, improve product quality, reduce the workload of weft breakage repair, and reduce production costs.

[0031] A barrier screen plate 602 is fixedly connected inside the ventilation hole 601. A cleaning plate 603 is movable on the outer surface of the barrier screen plate 602. A transmission disc 607 is fixedly connected to the end of the cleaning plate 603. The barrier screen plate 602 has holes of a certain size inside, which can block the fabric fibers adsorbed by the fan 7. The surface of the cleaning plate 603 has bristles. When the cleaning plate 603 rotates on the surface of the barrier screen plate 602, it can clean the fibers accumulated on the surface of the barrier screen plate 602 together. When the fibers gather to a certain extent, they will gradually form a clump. At this time, the clump of fibers will be thrown into the collection tank 604 under the action of centrifugal force as the cleaning plate 603 rotates, which facilitates the device to recycle the yarn fibers and reduce the waste of raw materials.

[0032] The transmission disc 607 is rotatably connected to the barrier screen plate 602. A connecting rod 608 is fixedly connected to the outer surface of the transmission disc 607. The connecting rod 608 passes through the barrier screen plate 602 and is rotatably connected to the barrier screen plate 602. When the fan 7 is running, the transmission rod 8 will drive the connecting rod 608 to rotate. The rotation of the connecting rod 608 will drive the transmission disc 607 to rotate. The rotation of the transmission disc 607 will drive the cleaning plate 603 to perform self-cleaning work on the surface of the barrier screen plate 602, thereby preventing fibers from clogging the barrier screen plate 602, simplifying the power structure of the device and improving the energy utilization efficiency of the device.

[0033] The anti-weft breakage bracket 1 has a collection groove 604 inside, and a recycling box 605 is slidably installed on the bottom surface of the anti-weft breakage bracket 1. The recycling box 605 is adapted to the collection groove 604. The bottom of the recycling box 605 also has a hole of a certain diameter. The ventilation hole 601 is designed with a slightly larger bottom diameter. When the fan 7 starts to adsorb the fibers in the guide ceramic head 4, most of the airflow will be directly drawn in through the ventilation hole 601. A small amount of gas will be released along the collection groove 604 and through the hole on the bottom surface of the recycling box 605, thereby causing the yarn ball to stay in the recycling box 605, which makes it convenient for the staff to recycle the yarn fibers.

[0034] The bottom surface of the anti-weft breakage bracket 1 is fixedly connected to a support frame 606, and the recycling box 605 is slidably connected to the support frame 606. The support frame 606 serves to limit and support the recycling box 605, enabling the recycling box 605 to stably collect yarn fiber clumps. Workers can remove the recycling box 605 from the support frame 606 to recycle the fiber clumps collected in the recycling box 605, thereby reducing the production cost of the mesh fabric.

[0035] Working principle: During use, the operator first fixes the anti-weft breakage bracket 1 in a suitable position, then passes the weaving yarn through the guide ceramic head 4. When the loom starts, the control fan 7 starts simultaneously. The guide ceramic head 4 can support and guide the passing yarn, and adjust its angle to a certain extent according to the stress change of the yarn, thereby absorbing part of the yarn tension peak and reducing the risk of yarn breakage. The fan 7 can adsorb the fiber material accumulated in the guide ceramic head 4, preventing fiber accumulation from clogging the guide ceramic head 4 and ensuring the normal passage of the yarn. At the same time, the fan 7 can also drive the cleaning plate 603 through the transmission rod 8 to clean the surface of the barrier screen plate 602, sweeping the fiber fabric accumulated on the surface of the barrier screen plate 602 into the recycling box 605. The operator can take out the recycling box 605 to recycle the fiber material, thereby reducing the waste of raw materials.
