In order to achieve the purpose, the utility model relates to a broken thread detection device of a warping machine, which comprises a creel, a yarn divider and a warping machine, wherein the yarn output by cheese on the creel enters a warping shaft of the warping machine for winding after passing through the yarn divider; two guide rollers are arranged between the creel and the yarn distributor, the two guide rollers are positioned at the same horizontal height, all yarns are conveyed from the lower ends of the guide rollers side by side, a first frame is arranged below the two guide rollers, a second frame is arranged above the two guide rollers, a row of guide holes in the vertical direction are arranged on the first frame along the axial direction of the guide rollers, each guide hole corresponds to the yarns below the guide rollers side by side one by one, a support rod is arranged in each guide hole, a guide wheel is arranged at the top of each support rod, an annular yarn guide groove is arranged on the circumferential surface of each guide wheel, a balancing weight is arranged on each support rod at the lower end of each guide hole, a limit plate is arranged on each support rod above the first frame, a pressure spring is sleeved on each support rod between each limit plate and the first frame, an upward connecting rod is arranged on each support rod, and a current-conducting, the upper end of the connecting rod is provided with a conductive ball, and the conductive plate and the conductive ball are respectively connected with an alarm through leads.

According to the technical scheme, the yarns can be real silks, namely silk yarns, according to actual application. The yarn is output from the bobbin yarn on the creel, passes through the lower part of the guide roller, enters the yarn divider and is wound on the warping shaft of the warping machine; in the process, the supporting rod in the guide hole and the guide wheel above the supporting rod are used for upwards supporting and tensioning the yarns, and the upward acting force is provided by the elasticity of the pressure spring and the gravity difference of the balancing weight to upwards tension the yarns. At this moment, a gap exists between the conductive ball at the end part of the connecting rod on the supporting rod and the conductive plate through selection of the balancing weight, and the pressing action of the yarn on the supporting rod disappears when the yarn is broken, so that the conductive ball is contacted with the conductive plate under the elastic action of the pressure spring to realize alarming. Above-mentioned in-process utilizes mechanical structure to realize the continuation detection to all yarns, and detection stability is high, can select suitable balancing weight according to the tension requirement of actual yarn moreover to ensure that tensile controllable is changeable.

As optimization, the warping machine further comprises a controller, wherein the controller is connected with the alarm and the warping machine; the yarn guiding device is characterized in that a first press rod is arranged on each of the first racks on two sides of the guide hole, two ends of each first press rod are connected to the first racks through first cylinders respectively, the first press rods are located below yarns, second press rods are arranged on the second racks corresponding to the first press rods, two ends of each second press rod are connected to the second racks through second cylinders, the corresponding first press rods and the corresponding second press rods are located on the same vertical plane, and the first cylinders and the second cylinders are controlled to move by controllers. Among the above-mentioned scheme, the intercommunication signal direct transfer to controller of alarm or electrically conductive ball and current conducting plate, the controller can control the warper and stop at once, so can avoid broken end yarn to get into the warper and influence the warping effect. The controller can control first cylinder, second cylinder simultaneous action simultaneously, and under the condition that takes place the broken string promptly, first depression bar, second depression bar move immediately and with all yarn centre gripping, and the warper is shut down simultaneously, can carry out the position with the yarn of broken end and prescribe a limit to, avoid the yarn to cause the confusion under external factors's influence and between the yarn on every side, also made things convenient for the follow-up joint of operation workman to the broken yarn to handle, promoted work efficiency.

The utility model provides a broken string detection device of warper, it can effectively realize carrying out the stable detection that lasts to the yarn through reasonable structural design, reacts when it takes place the broken string at once to control the warper and shut down, promote the stability and the reliability of warping process.
