Description
Technical Field

[0002] China is currently a major textile country in the world, and its textile industry occupies an important position in the national economy. The current textile equipment is generally a mechanical equipment for processing yarn or processing yarn into fabric. Therefore, the operation of its textile equipment is inseparable from the yarn, and the running yarn generally has tension. When the external force is greater than the limit tension of the yarn, it will cause the yarn to break. After the yarn breaks, the textile equipment needs to be stopped in time to avoid greater losses.
[0003] Generally, textile equipment needs to be equipped with a yarn break detection device to control the stop of the textile equipment. The existing yarn break detection device usually uses a device that places the yarn on a pressure sensor or other device that senses the yarn tension. When the yarn breaks, the tension changes, causing the detection device to alarm. However, due to the difference in material and thickness, the tension of the yarn itself is also different. The yarn break detection device in the prior art usually cannot adjust the size of the yarn tension it adapts to. When the yarn is replaced, the original yarn break detection device is prone to misjudgment or failure due to the change in tension. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1
[0021] like Figure 1-3 As shown, a tension-adjustable yarn breakage automatic detection device comprises a housing 1, the housing 1 is an inverted "L" shape, a limit slot 3 is provided at one end of a head 2 of the housing 1, and the function is to limit the upper and lower positions of a subsequent tension transmission member 9, a sensing slot 4 is provided below the head 2, a first rotating shaft 5 is provided inside the head 2, a second rotating shaft 6 is provided in the middle of the housing 1, an elastic force adjustment block 7 rotating around the second rotating shaft 6 is provided on the inner lower side of the housing 2, and an elastic force adjustment structure is provided at the bottom of the elastic force adjustment block 7;
[0022] The automatic detection device also includes a V-shaped elastic component 8 arranged in the shell 1. When the opening of the V-shaped elastic component 8 becomes smaller and smaller, the mutual elastic force between its two wings becomes greater. One end of the V-shaped elastic component 8 is connected to a tension transmission component 9 extending outside the limit groove 3 and rotating around the first rotating shaft 5. Specifically, a connecting groove is opened on the back of the tension transmission component 9, and one end of the V-shaped elastic component 8 is inserted into the connecting groove. The end of the tension transmission component 9 facing away from the V-shaped elastic component 8 is provided with a bridge block 24 for bridging the yarn. The tension of the yarn is used to apply pressure to the bridge block 24 so that the entire tension transmission component rotates downward, forming a countermeasure against the elastic force of the V-shaped elastic component 8. When the yarn breaks and loses tension, the tension transmission component 9 loses the pressure and countermeasure against the V-shaped elastic component 8 and rotates upward. The other end of the V-shaped elastic component 8 is connected to the elastic force adjustment block 7. Specifically, a connecting column 25 is provided at one end of the elastic force adjustment block 7. The other end of the V-shaped elastic component 8 is wound into a loop and arranged on the connecting column 25. A sensor component is provided at the bottom of the tension transmission component 9. The function of the sensor component is to use the change in the position of the tension transmission component 9 to alarm the disconnection situation. The shell 1 is connected to the upper cover as a whole through the mounting structure. The upper cover has the same shape as the shell 1, both of which are inverted "L" shape. In this embodiment, the mounting structure includes a plurality of mounting holes 27 arranged on the shell 1, and a plurality of mounting columns are provided on the upper cover, which are compatible with the mounting holes 27 in number, position and shape. The shell is closed by the cooperation between the mounting holes 27 and the mounting columns.
[0023] In this embodiment, the elastic force adjustment block 7 is fan-shaped, and an adjustment slot 10 is provided at the bottom of the housing 1. The housing 1 is provided with a plurality of slots 11 at annular intervals at the bottom of the elastic force adjustment block 7. In this embodiment, three slots 11 are provided, and slopes are provided on both sides of the slots 11. The slopes are provided to facilitate the user to adjust the elastic force adjustment block 7 and the adjustment of the block below the elastic force adjustment block 7. An elastic strip 23 and a handle 13 for manually moving the elastic force adjustment block 7 are provided at the bottom of the elastic force adjustment block 7. A block 12 matching the shape of the slot 11 is provided at one end of the elastic strip 23. When the elastic force adjustment block 7 is rotated upward for adjustment, the opening of the V-shaped elastic component is reduced, and the elasticity of its two wings is greater, so that the elastic force of the acceptable yarn is greater.
[0024] In this embodiment, the sensing component includes a magnet 17, and a detection circuit board 19 is provided under the tension transmission member 9. The detection circuit board 19 is provided with a Hall element 18 at a position corresponding to the magnet 17. When the tension transmission member 9 is rotated downward to the limit position, the Hall element 18 can sense the magnetic field of the magnet 17. The Hall element is a core component for detecting yarn breakage. When the yarn is broken, the magnet 17 is driven by the elastic force of the V-shaped elastic component and away from the Hall element 18. That is, when the yarn is broken, the Hall element cannot sense the magnet 17, thereby forming a yarn breakage signal. A further preferred technical solution is that the head 2 is provided with an indicator light 22 electrically connected to the detection circuit board 19, specifically, an indicator light is provided, and the specific yarn breakage is determined according to whether the indicator light is on or off or the color changes. Embodiment 2
[0025] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, an adjustment slot 10 is provided at the bottom of the housing 1, a fan-shaped gear 14 is fixedly connected to the bottom of the elastic force adjustment block 7, and a gear 15 adapted to the fan-shaped gear 14 is provided at the bottom of the housing 1. The fan-shaped gear 14 is driven by the gear 15 to rotate so that the elastic force adjustment block 7 moves upward or downward, thereby adjusting the elastic force of the V-shaped elastic component. Further, in order to be able to adapt and modify the tension of all yarn detection devices at the same time, a unified adjustment tooth plate 16 is provided under the gear 15, and multiple gears 15 share a unified adjustment tooth plate 16, and the gears 15 do not move relative to each other. Specifically, each yarn detection device is equipped with a gear, and multiple gears share a tooth plate. All yarn detection devices are adjusted simultaneously by unified adjustment of the tooth plate. In this embodiment, the adjustment method can be uniformly adjusted by electric drive to adjust the tooth plate. In some other embodiments, a mechanical adjustment method can be adopted. This application does not protect the adjustment method of the tooth plate. A further preferred technical solution is that the sensing component includes an arc-shaped light shielding plate 20, a detection circuit board 19 is provided under the tension transmission member 9, and a photoelectric tube and a light receiving component 21 are respectively provided on both sides of the arc-shaped light shielding plate 20. When the tension of the yarn just fits the yarn detection device, the tension transmission member rotates to the bottom, the arc-shaped light shielding plate 20 completely covers the photoelectric tube and the light receiving component 21, and the photoelectric sensor element does not work. When the tension of the yarn changes, the tension transmission member 9 rotates upward with the arc-shaped light shielding plate 20, and the light receiving component 21 can gradually receive the light from the photoelectric tube. The change in the yarn tension can be judged according to the amount of light received. When the yarn is completely broken, the tension transmission member 9 rotates upward to the limit position, the arc-shaped light shielding plate 20 is completely retracted, the light receiving component completely receives the light from the photoelectric tube, the indicator light is on, and the yarn is broken at this moment.
[0026] The working principle of the utility model is as follows: the yarn is laid on the tension transmission member 9, and the tension transmission member 9 is subjected to the pressure from the yarn and rotates downward around the first rotating shaft 5, so that the sensing member is connected and provides a downward elastic force for the V-shaped elastic member 8, which forms a stable confrontation with the elastic force of the V-shaped elastic member 8 itself. When the yarn breaks, the tension transmission member 9 loses the pressure from the yarn and is rebounded and rotated upward by the elastic force of the V-shaped elastic member 8, the sensing member is disconnected, and the yarn detection device alarms; when it is necessary to adapt and adjust according to the tension of the yarn, adjust the elastic force adjustment block to make it rise or fall to change the opening and closing angle of the V-shaped elastic member 8. The smaller the opening and closing angle, the greater the elastic force provided by the V-shaped elastic member 8, which can form a stable confrontation with the pressure provided by the yarn with large tension, and vice versa, so as to adapt to the tension of yarns of different materials or thicknesses and avoid allergies or failure of the yarn detection device. When the device is Figure 1 When the device is in the state of V-shaped elastic component 8, the elastic force is the smallest, which is used to adapt to the small yarn tension. Figure 2 In the state, the elastic force of the V-shaped elastic component 8 is the largest, which is used to adapt to the large yarn tension.
[0027] The utility model provides a V-shaped elastic component and uses an elastic force adjustment block to adjust the size of the opening of the V-shaped elastic component, thereby changing the elasticity of the V-shaped elastic component, thereby adjusting the size of the tension on the tension transmission member connected to the V-shaped elastic component, and realizing the tension adjustment of the yarn break detection device, which can adapt to yarns of different types and thicknesses, expand the scope of application, and reduce the replacement cost of the yarn break detection device.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
