Abstract
Description
Technical Field
[0001] This utility model relates to the field of ribbon weaving machine technology, and in particular to a ribbon weaving machine monitoring structure for a yarn breakage alarm device. Background Technology
[0002] Ribbon looms are widely used in textile production. Their main function is to weave yarn into various ribbons. During the operation of the ribbon loom, yarn breakage is a common fault. If yarn breakage is not detected and dealt with in time, it will lead to defects in the woven ribbons, affecting product quality. It will also cause waste of raw materials and a reduction in production efficiency.
[0003] Currently, although some weaving machines are equipped with yarn breakage monitoring devices, these devices have some shortcomings. For example, some monitoring devices use mechanical contact detection, which can easily cause wear to the yarn, affecting its strength and service life. Other monitoring devices are not sensitive enough and cannot issue an alarm in time when the yarn is slightly loose or about to break, resulting in the fault not being dealt with in a timely manner.
[0004] Therefore, this utility model proposes a weaving machine monitoring structure for a yarn breakage alarm device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a weaving machine monitoring structure for a yarn breakage alarm device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a weaving machine monitoring structure for a yarn breakage alarm device, including a rotating wheel assembly, which consists of a spinning wheel and connecting shafts arranged on both sides, and further includes a rotating groove on each side of the spinning wheel that is close to each other.
[0007] The detection assembly consists of an annular frame rotatably connected within a rotating groove. Positive magnetic plates are arranged within the annular frame, and the included angles between two adjacent positive magnetic plates are equal. A detection sensor is provided on the side of the spinning wheel closest to the annular frame, and a matching detection sensor is also provided on the side of the annular frame that is adapted to the spinning wheel.
[0008] Furthermore, a triggering component is provided on the spinning reel between the two annular frames. The triggering component is composed of an inner reel, and mounting seats are provided on both sides of the inner reel.
[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the triggering component forms a stable support structure between the two ring frames through the inner wire reel and the mounting seats on both sides. The inner wire reel can adapt to changes in yarn tension, and the mounting seats provide a stable assembly base for related components. This not only ensures the coordinated operation of the triggering component and the detection component, but also enhances the stability of the overall structure, reduces monitoring errors caused by loose components, and improves the reliability of wire breakage monitoring and the continuity of device operation.
[0010] Furthermore, the mounting base is provided with an annular tube frame, and a negative magnetic absorbing plate is provided on the outer side of the annular tube frame, and the negative magnetic absorbing plate is compatible with the positive magnetic absorbing plate.
[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the annular tube frame on the mounting base provides stable support for the negative magnetic plate, which is compatible with the positive magnetic plate on the annular frame. The magnetic attraction enables precise alignment and linkage between components. This magnetic attraction not only ensures synchronization during rotation but also reduces mechanical contact wear and improves structural durability. At the same time, the magnetic attraction sensing changes assist the detection component in accurately capturing the yarn state, enhancing the sensitivity and response speed of yarn breakage monitoring, and ensuring stable and efficient operation of the device.
[0012] Furthermore, the triggering component is provided with a defense line winding component, which is composed of a defense line winding wheel. The defense line winding wheel is provided with an arc-shaped anti-slip pad, which is distributed in a ring and the included angle between two adjacent arc-shaped anti-slip pads is equal.
[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: the anti-slip wheel on the trigger component guides the yarn direction through the arc-shaped anti-slip pad. The circularly distributed pad can evenly disperse the yarn tension, avoiding entanglement or deviation caused by excessive local force. The anti-slip design enhances the fit stability between the yarn and the wheel body, reduces damage caused by sliding friction, and at the same time, the regular distribution pattern ensures that the yarn running trajectory is consistent, providing a stable baseline state for subsequent monitoring, improving the overall device's accuracy in identifying abnormal yarn breakage, and ensuring a continuous and smooth weaving process.
[0014] Furthermore, an alarm light is provided on one side of the spinning reel located on the connecting shaft, and the input end of the alarm light is electrically connected to the output end of the detection sensor.
[0015] The advantages of adopting the above-mentioned further solution are: the alarm light on the side of the spinning wheel is electrically connected to the detection sensor, which can be activated in time when the sensor detects a broken thread signal. The light warning is intuitive and eye-catching, which can quickly remind the operator to deal with the abnormality, avoid the waste of raw materials or webbing quality problems caused by the failure to detect the broken thread in time, shorten the fault response time, reduce downtime losses, and at the same time, there is no need for continuous manual monitoring, reducing labor costs and ensuring that the weaving process is carried out efficiently and orderly.
[0016] Furthermore, the diameter of the annular frame is larger than the diameter of the annular tube frame, and the positive and negative magnetic attracting plates are distributed in equal positions.
[0017] The beneficial effects of adopting the above-mentioned further scheme are: the diameter of the ring frame is larger than that of the ring tube frame, which provides sufficient space for the relative movement of the two and avoids structural interference; the positive and negative magnetic attraction plates are distributed in corresponding positions to ensure uniform and stable magnetic attraction, guarantee the coordination and accuracy of component linkage, reduce monitoring delays or misjudgments caused by alignment deviations, enhance the stability of device operation, further improve the reliability of wire breakage monitoring, and help the weaving process to be continuously efficient.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, the ring frame rotates flexibly within the rotating groove of the detection assembly. The positive magnetic attracting plates inside are evenly distributed in a ring. In conjunction with the matching detection sensors on the spinning wheel and the ring frame, changes in the rotation state can be accurately captured. The regular distribution of the magnetic attracting plates ensures the stability of the sensing signal. The dual sensors work together to enhance the monitoring sensitivity, enabling timely detection of motion deviations caused by yarn abnormalities. This provides a reliable basis for yarn breakage warning, while reducing external interference and improving the accuracy and stability of the device's monitoring. Attached Figure Description

The regular distribution of the magnetic attracting plates ensures stable sensing signals. The synergistic effect of the dual sensors enhances monitoring sensitivity, enabling timely detection of movement deviations caused by yarn abnormalities, providing a reliable basis for yarn breakage warnings, while reducing external interference and improving the accuracy and stability of the device's monitoring.
[0033] A trigger assembly 3 is installed on the spinning reel 11 between two annular frames 21.
