Abstract
Description
Technical Field
[0001] This application relates to the field of textile machinery testing technology, and more specifically, to a device for detecting warp yarn breakage that facilitates threading. Background Technology
[0002] In the textile industry, warp and weft are among the core parameters of fabric weaving, directly affecting the fabric texture, density, and physical properties. Warp yarns are always parallel to the selvage, while weft yarns are perpendicular to the selvage. During the weaving process, yarn breakage often occurs. If yarn breakage is not detected in time and corresponding measures are not taken, it will lead to a decline in product quality and may even damage the equipment. Although electronic detection devices on the market, such as capacitive and inductive sensors, have improved detection accuracy to some extent, they may be affected by factors such as electromagnetic interference in complex working environments, resulting in inaccurate detection results.
[0003] Therefore, a device for detecting warp breakage that is easy to thread is needed to solve the above problems. Utility Model Content
[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a warp breakage detection device for easy threading, comprising: a bracket on which two parallel and front-to-back distributed ceramic rollers are rotatably mounted; two sliding frames slidably mounted on the bracket, distributed left and right, located between the two ceramic rollers; a mounting shaft mounted between the two sliding frames, with its axis parallel to the ceramic rollers; multiple sets of detection components rotatably mounted on the mounting shaft, distributed along the axis of the mounting shaft; and a detection rod mounted between the two sliding frames, located below the mounting shaft. Each detection component includes a collar sleeved on the mounting shaft, and a deflection frame and a deflection arm fixed to the outer wall of the collar. The deflection frame and deflection arm are located on opposite sides of the axis of the collar. The detection rod is provided with multiple sets of first contacts and multiple sets of audible and visual alarms, with each first contact corresponding to one of the audible and visual alarms. Second contacts are fixedly provided on the deflection arms, with each second contact on the deflection arms corresponding to one of the multiple sets of first contacts.
[0006] With the deflection arm and deflection frame in place, when wiring is required, the warp threads are simply placed on two ceramic rollers and distributed on them. Then, the sliding frame moves upward so that the contact wheel contacts the warp threads. While tensioning the warp threads, the collar rotates on the mounting shaft, causing the deflection arm to deflect and the second contact to disengage from the first contact. This eliminates the need to repeatedly wind the warp threads, making threading easier. When the warp threads break, the detection element rotates on the mounting shaft, causing the deflection arm to deflect and the second contact to contact the first contact. Power is supplied to the audible and visual alarm through the first contact, causing the audible and visual alarm to sound an alarm.
[0007] Furthermore, multiple electric slip rings are installed on the mounting shaft, and a conductive ring is provided on the inner side of the collar portion to conduct electricity in contact with the electric slip rings. The conductive ring is electrically connected to the second contact. A controller is fixedly installed on the sliding frame, and the controller is electrically connected to the multiple electric slip rings respectively.
[0008] Furthermore, a contact wheel is rotatably provided at one end of the slip ring, and the contact wheel is located between two ceramic rollers. Multiple guide grooves distributed along the axis are provided on the outer wall of the two ceramic rollers, and the guide grooves are directly opposite the contact wheel.
[0009] Furthermore, a screw is rotatably mounted on the bracket, the screw passes through the sliding frame and is threadedly connected to the sliding frame, and a handle is fixedly connected to the upper end of the screw.
[0010] By rotating the handle, the sliding frame moves up and down under the action of the screw, which in turn drives the mounting shaft and the detection piece to move up and down, so that the contact wheel can come into contact with the warp.
[0011] Furthermore, a torsion spring is provided between the mounting shaft and the collar portion, a first baffle is provided on the outer wall of the mounting shaft, and a second baffle is provided on the inner wall of the collar portion, with both ends of the torsion spring abutting against the first baffle and the second baffle respectively.
[0012] Furthermore, a ring is rotatably mounted on the mounting shaft, and a positioning screw is threaded onto the ring. One end of the positioning screw abuts against the mounting shaft to limit the ring. A second baffle is located inside the ring.
[0013] By rotating the ring, the deformation of the torsion spring is adjusted, thereby adjusting the tension on the warp.
[0014] The beneficial effects of this application are as follows:
[0015] 1. With the deflection arm and deflection frame in place, when wiring is required, simply place the warp threads on two ceramic rollers and distribute them on the rollers. Then, move the sliding frame upward so that the contact wheel contacts the warp threads. While tensioning the warp threads, the collar rotates on the mounting shaft, causing the deflection arm to deflect and the second contact to disengage from the first contact. This eliminates the need to repeatedly wind the warp threads, making threading easier. When the warp threads break, the detection element rotates on the mounting shaft, causing the deflection arm to deflect and the second contact to contact the first contact. Power is supplied to the audible and visual alarm through the first contact, causing the audible and visual alarm to sound an alarm.
[0016] 2. By rotating the handle, the sliding frame moves up and down under the action of the screw, which in turn drives the mounting shaft and the detection piece to move up and down, so that the contact wheel can come into contact with the warp.
[0017] 3. By rotating the ring, the deformation of the torsion spring is adjusted, thereby adjusting the tension on the warp. Attached Figure Description

[0035] Reference Figure 1-7A device for detecting warp breakage that facilitates threading includes: a support 10, ceramic rollers 11, a sliding frame 12, a mounting shaft 14, a detection element 17, and a detection rod 15. The support 10 has a base plate and two side plates. Two ceramic rollers 11 are rotatably mounted between the two side plates of the ceramic rollers 11. The two ceramic rollers 11 are distributed front to back with their axes parallel to each other. The warp thread extends front to back and is guided by the two ceramic rollers 11. Multiple sets of guide grooves 21 are formed on the outer walls of the two ceramic rollers 11, through which the warp thread is guided. A sliding frame 12 is also slidably mounted vertically on the two side plates. A screw 13 is rotatably mounted on the support 10, passing through the sliding frame 12 and threadedly connected to it. A handle is fixedly connected to the upper end of the screw 13. Rotating the handle causes the sliding frame 12 to move up and down under the action of the screw 13.
[0036] A mounting shaft 14 and a detection rod 15 are fixedly arranged between two sliding frames 12, with both ends of the mounting shaft 14 and the detection rod 15 fixed to the two sliding frames 12 respectively. The axes of the mounting shaft 14 and the detection rod 15 are parallel to the axis of the ceramic roller 11, and the detection rod 15 is located below the mounting shaft 14. A detection element 17 is sleeved on the mounting shaft 14. The detection element 17 includes a collar portion 22 sleeved on the mounting shaft 14, and a deflection frame 26 and a deflection arm 24 fixed on the outer wall of the collar portion 22. The deflection frame 26 and the deflection arm 24 are located on both sides of the axis of the collar portion 22. The detection rod 15 is provided with multiple sets of first contacts 19 and multiple sets of audible and visual alarms 20. The first contacts 19 correspond one-to-one with the audible and visual alarms 20. When one of the first contacts 19 is energized, the corresponding audible and visual alarm 20 sounds an alarm. A second contact 25 is fixedly mounted on the deflection arm 24, and the second contacts 25 on the multiple deflection arms 24 correspond one-to-one with multiple sets of first contacts 19. Multiple slip rings 16 are mounted on the mounting shaft 14, and a conductive ring 23 is provided inside the collar portion 22 to conduct electricity in contact with the slip rings 16. The conductive ring 23 is electrically connected to the second contacts 25. A controller 18 is fixedly mounted on the sliding frame 12, and the controller 18 is electrically connected to the multiple slip rings 16. When the detection element 17 is in its extreme position, one end of the deflection arm 24 contacts the outer wall of the detection rod 15. At this time, the second contacts 25 contact the first contacts 19 and energize the audible and visual alarm 20. The controller 18 controls the energization of the slip rings 16.
[0037] A contact wheel 27 is rotatably mounted on one end of the slip ring 16. The contact wheel 27 is located between two ceramic rollers 11. Multiple guide grooves 21 distributed along the axis are provided on the outer wall of the two ceramic rollers 11, and the guide grooves 21 are directly opposite the contact wheel 27. It should be noted that the deflection arm 24 is relatively heavy. In its natural state, under the action of gravity, one end of the deflection arm 24 rests against the detection rod 15, at which time the contact wheel 27 is tilted up.
[0038] After multiple warp threads are placed on two ceramic rollers 11, each warp thread is located in a number of guide grooves 21. Rotating the screw 13 causes the sliding frame 12 to move upwards, bringing the contact wheel 27 into contact with the warp threads and taut them. This causes the detection element 17 to rotate on the mounting shaft 14, deflecting the deflection arm 24. The second contact 25 then stops contacting the first contact 19 and energizing it. When the warp threads break, the detection element 17 rotates on the mounting shaft 14, deflecting the deflection arm 24 and bringing the second contact 25 into contact with the first contact 19. The first contact 19 then powers the audible and visual alarm 20, causing it to sound an alarm.
[0039] In one embodiment, a torsion spring 28 is provided between the mounting shaft 14 and the collar portion 22. A first baffle 31 is provided on the outer wall of the mounting shaft 14, and a second baffle 32 is provided on the inner wall of the collar portion 22. The two ends of the torsion spring 28 abut against the first baffle 31 and the second baffle 32 respectively, so that the detection element 17 can quickly return to the limit position through the torsion spring 28.
[0040] In one embodiment, a ring sleeve 30 is rotatably mounted on the mounting shaft 14, and a positioning screw 33 is threaded onto the ring sleeve 30. One end of the positioning screw 33 abuts against the mounting shaft 14 to limit the movement of the ring sleeve 30. A second baffle 32 is disposed inside the ring sleeve 30. When the ring sleeve 30 is rotated, the torsion spring 28 deforms under the action of the first baffle 31 and the second baffle 32. When the screw 13 is rotated, causing the contact wheel 27 to move upward, the contact wheel 27 contacts the warp thread, causing the torsion spring 28 to continue to deform, at which point the tension force on the warp thread is relatively large.
[0041] Working process or usage method:
[0042] 1. The warp threads are distributed on two ceramic rollers 11 and sequentially set in multiple guide grooves 21. At this time, the warp threads are located directly above multiple contact wheels 27. Then, by rotating the screw 13, the sliding frame 12 moves upward, so that the contact wheels 27 abut against the warp threads. At this time, the warp threads are tensioned and the detection element 17 rotates on the mounting shaft 14, so that the second contact 25 disengages from the first contact 19. Then, the controller 18 controls the electric slip ring 16 to be energized.
[0043] 2. When a wire break occurs, the torsion spring 28 causes the detection element 17 to return to its limit position. At this time, the second contact 25 contacts the first contact 19 and supplies power to the audible and visual alarm 20, which then sounds an alarm.
[0044] 3. When it is necessary to adjust the warp tension, by rotating the ring 30, since one end of the deflection arm 24 is abutting against the mounting shaft 14, the ring 22 cannot rotate, which will cause the torsion spring 28 to deform. Then, when the contact wheel 27 moves upward, the second contact point 25 will disengage from the warp 29 and generate a greater tension on the warp.
