Description

Technical Field

[0001] This utility model relates to the field of yarn breakage detection technology, and in particular to a yarn breakage detection device for a spinning frame. Background Technology

[0002] The ring spinning frame is the core equipment in the textile industry for twisting and winding yarn from roving to fine yarn. Its working principle involves high-speed rotation of spindles to draft, twist, and wind the roving, ultimately forming fine yarn that meets the required yarn count. As the final stage of the spinning process, the operational stability of the ring spinning frame directly affects yarn quality (such as evenness and hairiness index) and production efficiency (daily output of a single machine can reach 50-150 kg). To ensure stable operation of the ring spinning frame and prevent it from continuing to operate even when yarn breaks, a yarn breakage detection device is installed. While existing yarn breakage detection devices can detect yarn breaks, they have certain limitations. During production, the ring spinning frame produces multiple yarns with different output directions. Existing devices have a fixed detection angle when detecting yarn breaks and cannot be adjusted according to actual production needs. Therefore, the device's application range is limited, and it cannot be adjusted based on the number of yarns. Utility Model Content

[0003] This invention proposes a yarn breakage detection device for a spinning machine to solve the problem that the detection angle of existing devices is fixed and cannot be adjusted according to actual production needs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a yarn breakage detection device for a spinning machine, comprising a support member and a detection member. One side of the support member is open along its own length to form a connecting groove. The detection member includes a connecting part and a rotating plate. The connecting part is slidably connected to the inside of the connecting groove, and the rotating plate is rotatably connected to one side of the connecting part. A detection part for detecting yarn breakage is fixedly connected to the side of the rotating plate away from the connecting part, and a second limiting rod is screwed onto the rotating plate. The second limiting rod is located on one side of the detection part, and the free end of the second limiting rod extends to the other side of the rotating plate and contacts the base plate.

[0005] Preferably, the connecting part includes a substrate, and N substrates are provided in total, where N≥2. The substrates are slidably connected to the inside of the connecting groove. A first limiting rod is provided on both sides of the substrate. Two side grooves are symmetrically opened on the outside of the support member along the connecting groove. The side grooves are connected to the connecting groove, and the connecting groove is located between the two side grooves. The free end of the first limiting rod passes through the side groove and is screwed into the substrate.

[0006] Preferably, two guide rollers are symmetrically rotatably connected to the side of the rotating plate away from the substrate, and the circumferential surface of the guide rollers is recessed to form an annular groove.

[0007] Preferably, the detection part includes a guide ring, on which a guide hole is provided for the yarn to pass through, and a visual inspection camera is fixedly connected to the inner wall of the guide hole.

[0008] Preferably, the support member includes a guide rail plate, and the connecting groove and the side groove are both formed on the guide rail plate.

[0009] Preferably, a connecting plate is fixedly connected to the side of the guide rail plate away from the connecting groove, and a fixing screw is screwed onto the connecting plate.

[0010] Compared with the prior art, this application has the following advantages:

[0011] (1) The device is connected to the support through the connecting part and rotated around the connecting part by the rotating plate. Then, the position of the detection piece can be adjusted by the second limit rod, so that the detection piece can easily detect yarns input at different angles, thus expanding the scope of application of the device.

[0012] (2) By engaging the base plate with the connecting groove on the guide rail plate and by screwing the first limiting rod with the base plate, the number of yarns detected by the device can be adjusted according to the actual situation, further expanding the application range of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6 As shown, a yarn breakage detection device for a spinning machine includes a support member 1 and a detection member 2. The support member 1 has an open connecting groove 12 formed on one side along its own length direction. The detection member 2 includes a connecting part and a rotating plate 23. The connecting part is slidably connected to the inside of the connecting groove 12, and the rotating plate 23 is rotatably connected to one side of the connecting part. A detection part for detecting yarn breakage is fixedly connected to the side of the rotating plate 23 away from the connecting part, and a second limiting rod 29 is screwed onto the rotating plate 23. The second limiting rod 29 is located on one side of the detection part, and the free end of the second limiting rod 29 extends to the other side of the rotating plate 23 and contacts the base plate 21.

[0023] With the above technical solution, before production, the connecting part is engaged with the connecting groove 12 on the support 1, so that the connecting part is installed on the connecting part. The connecting part supports the rotating plate 23, and then the rotating plate 23 is pulled to rotate around the connecting part, thereby driving the detection part to rotate and adjusting the angle of the detection part. After the angle of the detection part is adjusted, the second limiting rod 29 on the rotating plate 23 is rotated. The second limiting rod 29 abuts against the connecting part, thereby fixing the angle of the rotating plate 23 and the detection part, making it easy to adjust the detection part according to the input angle of the yarn and improving the convenience of using the device.

[0024] Specifically, in one embodiment, regarding the aforementioned connection portion, as... Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the connecting part includes a base plate 21, and there are N base plates 21 in total, where N≥2. The base plates 21 are slidably connected to the inside of the connecting groove 12. A first limiting rod 22 is provided on both sides of the base plate 21. Two side grooves 13 are symmetrically opened on the outside of the support member 1 along the connecting groove 12. The side grooves 13 are connected to the connecting groove 12, and the connecting groove 12 is located between the two side grooves 13. The free end of the first limiting rod 22 passes through the side groove 13 and is screwed into the base plate 21.

[0025] In this embodiment, the substrate 21 is engaged with the connecting groove 12 on the support member 1, so that the substrate 21 is installed on the connecting part. The first limiting rod 22 passes through the side groove 13 and is screwed to the substrate 21 to fix the substrate 21 to the required position. Then, according to the above steps, the required number of substrates 21 are fixed on the connecting part. After all the substrates 21 are installed, the rotating plate 23 is pulled to rotate around the connecting part, thereby driving the detection part to rotate and adjusting the angle of the detection part. After the angle of the detection part is adjusted, multiple yarns can be detected simultaneously through the detection part.

[0026] To make the yarn move more smoothly, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, two guide rollers 24 are symmetrically rotated and connected to the side of the rotating plate 23 away from the base plate 21, and the circumferential surface of the guide rollers 24 is recessed to form an annular groove 25.

[0027] In this embodiment, before the yarn passes through the detection section, the yarn passes through two guide rollers 24 and cooperates with the annular groove 25 to make the yarn transport smoother and improve the efficiency of yarn detection.

[0028] Furthermore, in this utility model, regarding the aforementioned detection part, as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the detection part includes a guide ring 26, on which a guide hole 27 is provided for the yarn to pass through, and a visual inspection camera 28 is fixedly connected to the inner wall of the guide hole 27.

[0029] In this embodiment, after the yarn passes through the guide hole 27 on the guide ring 26, the yarn is inspected by the visual inspection camera 28.

[0030] Specifically, in one embodiment, regarding the aforementioned support member 1, as... Figures 1-4 As shown, the support member 1 includes a guide plate 11, and a connecting groove 12 and a side groove 13 are both formed on the guide plate 11.

[0031] In this embodiment, before using the device, the guide rail plate 11 is fixed at the position to be fixed. After the guide rail plate 11 is fixed, the substrate 21 is engaged with the connecting groove 12 on the support member 1, so that the substrate 21 is installed on the connecting part. The first limiting rod 22 passes through the side groove 13 and is screwed to the substrate 21 to fix the substrate 21 to the required position, so that the required number of substrates 21 are fixed on the connecting part.

[0032] In addition, in this utility model, to facilitate the fixing of the guide rail plate 11, such as... Figures 1-4 As shown, a connecting plate 14 is fixedly connected to the side of the guide rail plate 11 away from the connecting groove 12, and a fixing screw 15 is screwed onto the connecting plate 14.

[0033] In this embodiment, when it is necessary to fix the guide rail plate 11, the guide rail plate 11 is placed at the position where it needs to be fixed, and then the fixing screw 15 is passed through the connecting plate 14 and rotated. The fixing screw 15 is used to press the connecting plate 14, thereby fixing the guide rail plate 11.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
