Glass fiber cloth is an inorganic non-metallic material with excellent performance. It has excellent properties such as non-flammability, high temperature resistance, electrical insulation, high tensile strength, good chemical stability, and good corrosion resistance, making it an ideal reinforcing material, and is widely used in various industries and many occasions. At present, the equipment for glass yarn mainly includes yarn frame, yarn guide, sizing, shaping, drying, traction, warping and winding processes. The function of the warping machine is to wind the warp yarn wound on the yarn frame in parallel on the warp beam or weaving beam according to the number, length and amplitude required by the process design, for use in the drawing and machine process.

[0005] The second object of the present invention is to provide a detection method for a yarn breakage detection device of a warp doubling machine, aiming to avoid the situation where abnormal yarn breakage cannot be detected and intercepted in time, which directly affects the overall quality of the warp weaving beam and the warp yarn.

[0006] The present invention provides a yarn breakage detection device for a warping machine, comprising: a warping machine frame, rollers and warp yarns, characterized in that it comprises a laser detection device, and the laser detection device is installed on the lower side of the rollers;

[0007] The warping machine frame includes a frame base, a first warping machine shaft frame and a second warping machine shaft frame, wherein the first warping machine shaft frame and the second warping machine shaft frame are both connected to the frame base;

[0008] The laser detection device comprises a laser transmitter and a laser receiver;

[0038] The technical solution of the present invention is to set a laser transmitter 4 and a laser receiver 5, and set the laser transmitter 4 and the laser receiver 5 on the lower side of the roller 9. When yarn breakage occurs, the laser transmitter 4 and the laser receiver 5 can feed back the yarn breakage signal, so that the warp winding machine stops working, avoiding the situation where the yarn breakage abnormality cannot be detected and intercepted in time, which directly affects the overall quality of the warp weaving shaft and the warp yarn.

[0039] The laser detection device also includes a fixing bracket 6, through which the laser transmitter 4 is mounted on the first warping machine frame 2, and the laser receiver 5 is mounted on the second warping machine frame 3.

[0042] S1: Install the laser transmitter 4 on the first warping machine shaft frame 2 through the fixing bracket 6;

[0043] S2: Mount the laser receiver 5 on the second warping machine shaft frame 3 through the fixing bracket 6;

[0044] S3: start the warping machine;

[0045] S4: When the warp yarns are normally aligned, the laser transmitter 4 and the laser receiver 5 operate normally, and the warping machine operates normally;

[0046] S5: When the warp yarn breaks, the broken yarn enters the detection range of the laser transmitter 4 and the laser receiver 5, and the broken yarn cannot pass the laser, and the laser receiver 5 cannot receive the signal, that is, the yarn is determined to be broken, and the signal is transmitted to the PLC controller, and the PLC controller shuts down the warping machine. In step S5, the signal of yarn breakage is also transmitted to the alarm indicator 7, and the alarm indicator 7 sounds an alarm. In step S5, the warping machine can also be shut down directly through the power controller 8.

[0047] The control system corresponding to the PLC controller is also equipped with a data recording function, which can save information such as the time and location of each yarn break for a long time, helping factory managers to carry out quality control and process optimization.
