Technical Field
[0001] The utility model relates to the technical field of doubling machines, in particular to a doubling device capable of automatically cutting off threads and leaving tails. Background Art
[0002] In the yarn manufacturing process, a doubling machine is often used to combine single raw yarn into multiple yarns. In order to ensure the quality of the yarn, the raw yarn needs to be stably transported during the doubling process, while avoiding the breakage of the raw yarn. When the yarn breaks, the machine needs to be stopped in time and the yarn needs to be spliced.
[0003] In combination with the actual application of the existing technology, it is found that when the raw yarn breaks or the raw yarn bobbin is completely unwound, it cannot be detected in time and effectively, and it cannot be stopped quickly, which is not conducive to ensuring the quality of the strands, thereby affecting the quality of subsequent weaving. Therefore, we propose a yarn doubling device that can automatically break the thread and leave the tail, so as to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a yarn doubling device that can automatically break the thread and leave the tail, so as to solve the problem that the current yarn doubling machine proposed in the above background technology cannot timely and effectively monitor the yarn breakage or the yarn relaxation after complete feeding during the actual yarn doubling textile operation, which is not conducive to rapid shutdown and affects the yarn quality.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a yarn doubling device capable of automatically cutting off the yarn and leaving the tail, comprising: a support base and a yarn base installed on the front side of the support base;
[0006] Also includes:
[0007] A yarn drum, wherein the yarn drum is correspondingly rotated and clamped on the upper side of the support base;
[0008] A light sensing mechanism, wherein the light sensing mechanism is fixedly mounted on the top front side of the support base through a mounting frame, and a front hook is mounted on the end of the light sensing mechanism, and an optical fiber sensor is arranged on the inner side of the front hook;
[0009] The optical fiber sensor is composed of a first optical fiber tube, a second optical fiber tube, an optical fiber sensor amplifier and a controller. The first optical fiber tube and the second optical fiber tube are fixed in parallel, and the first optical fiber tube and the second optical fiber tube are connected to the controller via the optical fiber sensor amplifier.
[0010] A top seat, the top seat is fixedly connected to the top of the support base, and a wire hook located above the mounting frame is installed at the front bottom of the top seat, and an electronic tensioner and a tension sensor are installed in sequence above the wire hook;
[0011] A single spindle assembly is arranged on the top outer side of the top seat, and a lifting handle located at the top end of the top seat is arranged on the inner side of the single spindle assembly.
[0012] Preferably, a yarn detection sensor fixed on the surface of the yarn base is arranged below the yarn tube, and the yarn tube and the yarn detection sensor are arranged correspondingly.
[0013] Preferably, the number of the photosensitive sensing mechanisms is consistent with the number of the yarn bobbins.
[0014] Preferably, the controller output signal is connected to a control board inside the single spindle assembly.
[0015] Preferably, a front roller located at the top of the top seat is provided on the top rear side of the single spindle assembly, and the front roller is close to the winding mechanism on the inner side of the lifting handle.
[0016] Preferably, a winding drum connecting seat is installed on the outer side of the end of the lifting handle.
[0017] Compared with the prior art, the utility model has at least the following beneficial effects: the yarn doubling device capable of automatically cutting off the yarn and leaving the tail can timely and effectively monitor the yarn status, thereby ensuring rapid and timely shutdown, ensuring the tail is left, and thus facilitating wiring and ensuring the quality of the spinning;
[0018] 1. In this scheme, a first optical fiber tube, a second optical fiber tube, an optical fiber sensor amplifier and a controller are provided. A single strand of yarn tube corresponds to a group of optical fiber sensors. Through signal detection, a threshold is set in the optical fiber sensor amplifier. When the amount of light input detected by the optical fiber sensor is less than the set threshold, the optical fiber sensor amplifier will output a high level (24V) to the connected controller. Taking three strands of yarn as an example, as long as the controller detects a high level signal in the three optical fiber sensor amplifiers, the controller will immediately output a signal to the single spindle control board of the doubling machine. The single spindle control board of the doubling machine will stop working immediately after receiving this signal to realize the tail retention function, so as to facilitate the joint and ensure the yarn quality;
