Description

Technical Field

[0001] This utility model relates to the field of textile equipment, specifically a yarn breakage detection device. Background Technology

[0002] Textile machinery refers to the various mechanical devices necessary for processing natural or chemical fibers into textiles. These machines play a crucial role in the modern textile industry. However, in actual use, textile machinery frequently experiences thread breakage, which not only affects production efficiency but also leads to the production of defective or even waste products.

[0003] To address this issue, several automatic shutdown devices have emerged in existing technologies. For example, a Chinese patent discloses an automatic shutdown device for yarn breakage on a silk loom. This device includes a silk loom body with a U-shaped detector mounting bracket. A laser detector is located at the opening of the U-shaped bracket and is connected to a control box via a guide rod. A closed circuit connecting the detector and the control box is embedded within the guide rod. This design effectively detects yarn breakage and automatically stops the machine when the yarn breaks, reducing the generation of defective and waste products. However, this device has high environmental requirements, such as specific requirements for light stability and cleanliness, which limits its application in certain environments. Furthermore, the use of a laser detector increases the cost and complexity of the equipment. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-7 As shown, in some embodiments, the device for detecting thread breakage includes a signal receiving mechanism 1, a fixing component 2, a guide component 3, and a detection component 4. Specifically, the signal receiving mechanism 1 is designed to be mounted on the upper part of the fixing component 2, while the guide component 3 is disposed on one side of the fixing component 2. The detection component 4 is cleverly disposed inside the fixing component 2 and corresponds to the position of the signal receiving mechanism 1 to facilitate accurate detection.

[0030] The fixing component 2 includes an arc-shaped plate 22 with multiple wire-passing grooves 23 and multiple mounting grooves 27 evenly distributed on it. These wire-passing grooves 23 are arranged in an array along the transverse direction of the arc-shaped plate 22, ensuring that multiple wires can pass through them individually. Simultaneously, the mounting grooves 27 correspond one-to-one with these wire-passing grooves 23, and are respectively positioned at the center of the wire-passing grooves 23. This arrangement allows the detection component 4 to be mounted at the center of the arc-shaped plate 22.

[0031] Specifically, the detection component 4 consists of multiple detection mechanisms, each corresponding to one of the mounting slots 27 on the fixing component 2. Each detection mechanism is tightly connected to its corresponding mounting slot 27, ensuring that every single thread can be detected. Specifically, when the thread passes through the thread guide 23, any thread breakage can be quickly and accurately detected by the detection component 4, thereby improving production efficiency and product quality.

[0032] It should be noted that the fixing component 2 in this embodiment is installed on the loom, and each warp thread on the loom passes through the guide component 3, then through the fixing component 2, passes through the thread groove 23 and the detection mechanism in sequence, and then passes out of the fixing component 2 to complete the detection operation of the thread.

[0033] After the thread passes through the guide assembly 3, the guide assembly 3 performs preliminary sorting of the thread, and then the detection mechanism and the signal receiving mechanism 1 cooperate to detect it, completing the detection operation of the thread before weaving, reducing the impact of thread breakage on the quality of the fabric, thereby improving the quality of the fabric.

[0034] Furthermore, in some embodiments, the fixing component 2 further includes a fixing frame 21, a fixing end plate 25, a lower sealing plate 26, and a support plate 29. The arc-shaped plate 22 is disposed within the fixing frame 21, which provides support for the arc-shaped plate 22. The support plate 29 is disposed at the lower part of the arc-shaped plate 22, and the detection mechanism is connected to the support plate 29, which stably supports the detection mechanism. The lower sealing plate 26 is used to fix the bottom of the fixing frame 21.

[0035] Specifically, the fixed end plate 25 is disposed on one side of the fixed frame 21. Multiple wire-passing holes 28 are provided on both sides of the fixed frame 21. These wire-passing holes 28 are evenly distributed on both sides of the fixed frame 21 and correspond one-to-one with multiple wire-passing grooves 23. The wire passes through the wire-passing hole 28 on one side, through the wire-passing groove 23, the detection mechanism, and the wire-passing groove 23, and then passes through the wire-passing hole 28 on the other side. Multiple fixed end plates 25 are provided, with each pair of fixed end plates 25 disposed on both sides of a wire-passing hole 28, and connected to the guide assembly 3 through the fixed end plates 25 to provide support.

[0036] In addition, adjustment plates 24 are provided at both ends of the fixed frame 21. These two adjustment plates 24 are used to connect with an external weaving machine. According to specific needs, the position of the device can be adjusted by adjusting the adjustment plates 24 to achieve the best detection effect.

[0037] like Figure 7 As shown, in some embodiments, the guide assembly 3 includes a connecting post 31, a guide ring 32, and two first springs 33. Specifically, the guide ring 32 is positioned at the middle of the connecting post 31 and is welded and fixed to the connecting post 31, forming a single unit. In particular, the two ends of the connecting post 31 are respectively axially connected to the fixed end plate 25, allowing the guide assembly 3 to rotate.

[0038] The first spring 33 is located on the outside of the connecting post 31. One end of the first spring 33 is fixedly connected to the fixed end plate 25, and the other end is fixedly connected to the outside of the guide ring 32. The position of the guide ring 32 is adjusted by the first spring 33. Furthermore, the design of this guide assembly 3 allows the wire to pass smoothly through the guide ring 32, while the elasticity of the first spring 33 ensures that the guide ring 32 creates some resistance for the wire to pass through smoothly, thereby detecting problems such as wire breaks. This improves the accuracy and reliability of wire breakage detection. In addition, by fixing one end of the first spring 33 to the fixed end plate 25 and the other end to the outside of the guide ring 32, precise control of the guide ring 32 is achieved, ensuring the stable operation of the wire during the detection process and reducing misjudgments caused by the instability of the guide assembly 3.

[0039] like Figure 5 As shown, in some embodiments, the detection mechanism includes a signal plate 42, a damping rod 43, a second spring 44, and a base plate 45. Specifically, the damping rod 43 is carefully positioned between the signal plate 42 and the base plate 45, a layout that helps provide the necessary damping effect during the detection process. In particular, the second spring 44 is cleverly arranged on the outside of the damping rod 43 to ensure stable elastic support during the detection process, providing a stable upward force to the damping rod 43, thereby improving the sensitivity of the detection mechanism.

[0040] Furthermore, the sidewalls of the signal board 42 and the mounting groove 27 are designed to slide together, allowing the signal board 42 to move flexibly up and down during detection, thereby improving detection sensitivity and accuracy. The base plate 45 is firmly fixed to the support plate 29, ensuring the stability of the entire detection mechanism.

[0041] Finally, a detection hole 41 is specially designed in the signal board 42, which is directly connected to the wire guide groove 23. This design allows any wire breakage when the wire passes through the wire guide groove 23 and then through the detection hole 41 to be detected in a timely manner. Through the cooperation between the signal board 42 and the signal receiving mechanism 1, and with the analysis and processing by an external processor, real-time monitoring and alarm of wire breakage can be achieved.

[0042] like Figure 3 As shown, in some embodiments, the signal receiving mechanism 1 includes a connecting plate 11 and multiple receivers 12. These receivers 12 are configured one-to-one with multiple detection mechanisms, ensuring that each detection mechanism has a corresponding receiver 12 for signal reception. The receivers 12 are fixedly connected to the connecting plate 11, a design that ensures the stability of the receivers 12 during device operation. Furthermore, the connecting plate 11 is also fixedly connected to the top of the fixed frame 21. This connection method provides good fixation of the entire signal receiving mechanism 1 to the fixed frame 21, thereby ensuring the stability of the entire device and the accuracy of detection.

[0043] like Figure 5 As shown, in some embodiments, the detection hole 41 is designed with an arc shape to better accommodate the passage of the thread. Pressure sensors are specifically provided on the wall of the detection hole 41, which can accurately detect pressure changes in the thread as it passes through the detection hole 41. In this way, the device can monitor the state of the thread in real time, and once an abnormal pressure change is detected, it can determine whether the thread has broken. This design not only improves the accuracy of detection but also enhances the stability and reliability of the device.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
