Description

Technical Field

[0001] This utility model relates to the field of yarn breakage detection technology, specifically to an auxiliary device for yarn breakage detection. Background Technology

[0002] Yarn breakage detection is a key technology in the textile industry, used to monitor yarn breakage in real time, prevent equipment damage and production interruptions, and improve production efficiency and product quality.

[0003] Existing yarn breakage detection requires the use of corresponding yarn breakage detection sensors. Yarn breakage sensors are key devices in textile machinery used to monitor yarn breakage. Their core function is to detect the yarn status in real time through photoelectric or machine vision technology and trigger alarm or stop signals when yarn breaks in order to ensure production continuity and product quality.

[0004] In existing yarn breakage sensors, the yarn passes through the notch at the sensor end during use. However, in actual detection, yarn skips and jumps out of the notch, affecting detection accuracy. Therefore, we propose an auxiliary device for yarn breakage detection. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for detecting yarn breakage, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn breakage detection auxiliary device, comprising a base, a support column fixedly installed on the top of the base, a yarn breakage sensor connected to the top of the support column via a connecting component, and a notch provided on the outer end face of the yarn breakage sensor;

[0007] An arc-shaped plate is hinged to the notch via a damping pivot. The arc-shaped plate is a hollow structure. Multiple evenly distributed air outlets are opened on the inner wall of the arc-shaped plate. An ion air duct is fixedly connected to the middle of the outer wall of the arc-shaped plate.

[0008] By adopting the above technical solution, the device is first fixedly installed at the point of use. Then, the yarn slides into the notch along the edge of the arc-shaped plate. During use, the yarn breakage sensor monitors the breakage in real time. Simultaneously, the arc-shaped plate limits the yarn's movement, preventing yarn skipping and thus avoiding the yarn jumping out of the notch and affecting detection. The ion air duct guides the ion air into the inner cavity of the arc-shaped plate and out through the air outlet, allowing the ion air to be blown onto the yarn, further preventing it from moving towards the notch opening. The ion air also blows away any loose yarn debris by blowing it against the inner wall of the notch. Furthermore, the ion air helps prevent electrostatic adhesion, improving the blowing effect and preventing debris adhesion from affecting the detection results.

[0009] In a preferred embodiment of the present invention, the connecting assembly includes a retainer, a rotating shaft is rotatably mounted on the inner wall of the retainer, a fixing block is fixedly connected to the outer wall of the rotating shaft, the top of the fixing block is fixedly connected to the yarn breakage sensor, and a driving assembly is mounted on one side wall of the retainer.

[0010] By adopting the above technical solution, the drive component can drive the rotating shaft to rotate, thereby driving the fixed block and the yarn breakage sensor to rotate, thereby adjusting the angle of the yarn breakage sensor to adapt to the direction of the yarn.

[0011] In a preferred embodiment of this utility model, the drive assembly includes a fixed housing, which is fixed to the side wall of the retainer. A short shaft is rotatably mounted inside the fixed housing. One end of the short shaft movably passes through the fixed housing and the retainer and is fixedly connected to a rotating shaft. A worm gear is fixedly fitted on the outer wall of the short shaft. A worm is meshed on the outer wall of the worm gear. One end of the worm is rotatably connected to the inner wall of the fixed housing, and the other end of the worm movably passes through the fixed housing and is fixedly connected to a rotating block.

[0012] By adopting the above technical solution, rotating the worm gear can drive the worm wheel to rotate, thereby causing the short shaft to rotate, which in turn drives the rotating shaft to rotate, indirectly driving the yarn breakage sensor to rotate.

[0013] In a preferred embodiment of this utility model, the air outlet is inclined downward.

[0014] By adopting the above technical solution, the inclined air outlet can make the blown debris move downward, thereby improving the effect of blowing away the debris.

[0015] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application provides a yarn breakage detection auxiliary device, in which an arc-shaped plate is hinged to the notch of the yarn breakage sensor via a damping shaft. This allows the arc-shaped plate to fit against the inner wall of the notch, thereby limiting the yarn position and preventing skipped yarns from affecting the accuracy of the detection. Furthermore, the yarn can slide directly into the arc-shaped plate along its edge, thus improving the ease of threading.

[0018] The arc-shaped plate has air outlets on its inner wall, allowing ion air to be introduced into the inner cavity of the arc-shaped plate through the ion air pipe. The ion air is then blown towards the inner wall of the notch, which can blow away the yarn debris. The ion air also helps to avoid electrostatic adhesion, which improves the blowing effect and helps to prevent debris adhesion from affecting the detection effect.

[0019] Rotating the worm gear drives the worm wheel to rotate, which in turn drives the shaft to rotate, thereby causing the yarn breakage sensor to rotate and adjust the angle to adapt to the direction of the yarn. Attached Figure Description

[0029] Please see Figure 1-4 The present invention provides a technical solution: a yarn breakage detection auxiliary device, including a base 1, a support column 11 fixedly installed on the top of the base 1, a yarn breakage sensor 14 connected to the top of the support column 11 through a connecting component, and a notch opened on the outer end face of the yarn breakage sensor 14.

[0030] An arc-shaped plate 3 is hinged to the notch via a damping pivot. The arc-shaped plate 3 is a hollow structure. Multiple evenly distributed air outlets 32 are opened on the inner wall of the arc-shaped plate 3. An ion air duct 31 is fixedly connected to the middle of the outer wall of the arc-shaped plate 3.

[0031] It should be understood that in actual use, the device is first fixedly installed at the point of use, and then the yarn is slid into the notch along the edge of the arc plate 3. During use, the yarn breakage sensor 14 monitors the yarn breakage in real time. At the same time, the arc plate 3 can limit the yarn during use, which helps to prevent the yarn from skipping and thus prevents the yarn from jumping out of the notch and affecting the detection. Meanwhile, the ion air pipe 31 can guide the ion air into the inner cavity of the arc plate 3 and out through the air outlet 32, so that the ion air can be blown towards the yarn, which helps to further prevent the yarn from moving towards the notch opening. The ion air can also be blown towards the inner wall of the notch, which can blow away the yarn debris. Furthermore, the ion air helps to prevent electrostatic adhesion, which helps to improve the blowing effect and thus prevents the debris from adhering and affecting the detection effect.

[0032] Furthermore, mounting holes are provided at the four corners of the top of the base 1, which facilitates the installation and fixation of the entire device.

[0033] Furthermore, the air outlet 32 ​​is inclined downwards, which allows the blown debris to move downwards, thereby improving the effect of blowing away the debris.

[0034] like Figure 1 and 2 As shown; the connecting assembly includes a retainer 12, a rotating shaft 13 is rotatably mounted on the inner wall of the retainer 12, a fixing block is fixedly connected to the outer wall of the rotating shaft 13, the top of the fixing block is fixedly connected to the yarn breakage sensor 14, and a drive assembly is mounted on one side wall of the retainer 12.

[0035] It should be understood that the drive assembly can drive the rotating shaft 13 to rotate, thereby driving the fixed block and the yarn breakage sensor 14 to rotate, thereby adjusting the angle of the yarn breakage sensor 14 to adapt to the direction of the yarn.

[0036] like Figure 1 and 2 As shown in Figure 3, the drive assembly includes a fixed housing 2, which is fixed to the side wall of the retainer 12. A short shaft 21 is rotatably mounted inside the fixed housing 2. One end of the short shaft 21 movably passes through the fixed housing 2 and the retainer 12 and is fixedly connected to the rotating shaft 13. A worm gear 22 is fixedly fitted on the outer wall of the short shaft 21. A worm 23 meshes with the outer wall of the worm gear 22. One end of the worm 23 is rotatably connected to the inner wall of the fixed housing 2, and the other end of the worm 23 movably passes through the fixed housing 2 and is fixedly connected to a rotating block.

[0037] It should be understood that by rotating the worm gear 23, the worm wheel 22 can be driven to rotate, thereby causing the short shaft 21 to rotate, which in turn drives the rotating shaft 13 to rotate, and indirectly drives the yarn breakage sensor 14 to rotate.
