Technical Field
[0001] This utility model relates to the field of yarn breakage detection technology, specifically a yarn breakage detection and stopping device for water jet weaving. Background Technology
[0002] Combining a yarn breakage detector with water-jet weaving equipment can effectively monitor yarn breaks during the weaving process and automatically stop the equipment when a yarn breakage occurs. This can prevent fabric quality problems and improve production efficiency.
[0003] The connecting wires in the broken wire detector are usually quite long for easy power connection. However, when their length is much greater than the distance between the bottom of the broken wire detector and the power socket, the connecting wires are prone to dangling on the water jet loom and coming into contact with the moving parts of the loom, causing the connecting wires to bend or be damaged. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a broken yarn detection and stop device for water jet weaving, so as to solve the problem mentioned in the background art that the connecting wire of the broken yarn detector is easy to dangle on the water jet weaving machine.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a broken yarn detection and stopping device for water jet weaving, comprising a support structure, a broken yarn detector inserted into the support structure, and a wire assembly installed on the support structure;
[0006] The wire assembly includes an extension plate fixedly mounted on a support structure. The extension plate is rotatably connected to a rotating shaft. A linear clamp is installed in the middle of the rotating shaft for mounting the wire connecting wire of the broken wire detector. A gear dial is installed at one end of the rotating shaft, and a limiting structure that meshes with the gear dial is installed on the extension plate.
[0007] Preferably, the linear clip consists of a positioning part and an extension part. The outer surface of the positioning part has three linear through slots arranged in a ring, and the outer wall of the positioning part has an arc-shaped groove that communicates with one of the linear through slots.

[0011] Preferably, the support structure includes a support frame fitted onto the bottom of the broken wire detector, and the back of the support frame has an opening groove extending to the bottom.
[0012] Preferably, a circular sleeve is installed at the extended end of the front of the support frame, and a threaded cylinder is rotatably connected inside the circular sleeve, and a lead screw seat is connected inside the threaded cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model can hold the wire of the broken wire detector with a linear clamp, and the angle of the swinging linear clamp can be adjusted so that the wire held by the linear clamp extends along a set path direction, avoiding drooping on the water jet loom and interfering with the operation of other structures.

[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] Please see Figures 1-4 This invention proposes a broken yarn detection and stopping device for water jet weaving, mainly composed of a support frame 1 and a broken yarn detector 2 inserted into the support frame 1. A wire assembly 3 is also installed on the support frame 1. The broken yarn detector 2 is installed in the area where the yarn passes through the water jet weaving machine, near the top or side of the yarn. It monitors the yarn's condition in real time by detecting yarn tension and optical changes. The broken yarn detector 2 emits a laser beam and receives the reflected signal. If the yarn breaks, the reflected signal changes, and the detector can immediately detect this change. It is typically equipped with a control signal transmission structure, designed to send a signal to the control system of the water jet weaving machine when a broken yarn occurs. Upon receiving the signal, the control system immediately triggers a stop operation for the water jet weaving equipment, helping to stop the weaving process promptly and avoid further fabric damage or waste. This signal is controlled by a PLC system in the prior art, and therefore will not be described in detail here.
[0023] As mentioned above, under normal circumstances, the connecting wire 201 of the broken filament detector 2 is quite long and easily dangles on the water jet loom. To effectively solve this problem, such as... Figures 1-3As shown, the wire assembly 3 includes an extension plate 301 fixedly mounted on the support structure 1. The extension plate 301 is rotatably connected to a rotating shaft 302. A linear clamp 303 is installed in the middle of the rotating shaft 302 for mounting the connecting wire 201 of the broken wire detector 2. A gear dial 304 is installed at one end of the rotating shaft 302. A limiting structure 305 that meshes with the gear dial 304 is installed on the extension plate 301. The limiting structure 305 includes a telescopic device 3051 installed on the bottom wall of the extension plate 301. A toothed block 3052 adapted to the gear dial 304 is installed on the top of the telescopic device 3051. The width of the toothed block 3052 is greater than the thickness of the gear dial 304, so as to provide a force application point for the operator to press the toothed block 3052 downwards. Furthermore, the telescopic range of the telescopic device 3051 is greater than the tooth depth of the gear dial 304. By inserting the connecting wire 201 of the broken wire detector 2 into the linear clamp 303, and applying downward pressure to the toothed block 3052 as needed, the telescopic device 3051 retracts inward, while the toothed block 3052 disengages from the gear dial 304. Then, rotating the gear dial 304 causes the rotating shaft 302 to rotate by a set angle, thereby adjusting the swing direction of the linear clamp 303, causing the connecting wire 201 held by the linear clamp 303 to extend along a set path. After the direction adjustment is complete, the pressure applied to the toothed block 3052 is removed, and the telescopic device 3051 returns to its original position while simultaneously moving the toothed block 3052 upward, causing it to re-engage with the gear dial 304. This effectively prevents the linear clamp 303 from swinging unnecessarily under the weight of the connecting wire 201.
[0024] Specifically, the linear clamp 303 consists of a positioning part 3031 and an extension part 3032. The outer surface of the positioning part 3031 has three annularly arranged linear through-slots 3033. The outer wall of the positioning part 3031 has an arc-shaped groove 3034 that communicates with one of the linear through-slots 3033. The bottom of the linear through-slot 3033 is at the same height as the bottom of the positioning part 3031, and the bottom of the arc-shaped groove 3034 is at the same height as the bottom of the linear through-slot 3033. The extension part 3032 is slidably connected to the positioning part 3031 through the linear through-slots 3033 and the arc-shaped groove 3034. The arc-shaped groove 3034 limits the range of vertical sliding of the extension part 3032 along the positioning part 3031, and the inner diameter of the extension part 3032 is completely consistent with the inner diameter of the positioning part 3031, fitting the diameter of the connecting wire 201, thereby ensuring the effective contact area when clamping the connecting wire 201. Furthermore, the combined length between the extension portion 3032 and the positioning portion 3031 can be adjusted according to the required length of the clamping wire 201.
[0025] The opening width of the linear clip 303 is slightly smaller than the diameter of the connecting wire 201. In addition, the inner walls of the extension portion 3032 and the positioning portion 3031 are equipped with a rubber layer, which has a certain elasticity and can shrink in thickness when squeezed. Therefore, it is convenient for the connecting wire 201, whose diameter is slightly larger than the opening width of the linear clip 303, to be squeezed into the interior of the linear clip 303. Furthermore, the elastic rubber layer increases the effectiveness of clamping the connecting wire 201.
[0026] like Figure 1 and Figure 4 As shown, the support structure 1 includes a support frame 101 fitted onto the bottom of the broken wire detector 2, and the back of the support frame 101 has an opening slot 1011 extending to the bottom. When the broken wire detector 2 is inserted, it provides a channel for the passage of the connecting wire 201.
[0027] A circular sleeve 102 is installed on the extended end of the front of the support frame 101. A threaded cylinder 103 is rotatably connected inside the circular sleeve 102, and a lead screw seat 104 is connected inside the threaded cylinder 103. By rotating the threaded cylinder 103 up or down along the outer surface of the lead screw seat 104, the circular sleeve 102 can be moved up and down accordingly. The support frame 101 then moves the broken yarn detector 2 up and down accordingly, which allows for small-scale adjustment of the height of the broken yarn detector 2 according to the height of the yarn in the water jet loom, thus improving its adaptability.
