Description

Technical Field

[0001] This utility model relates to the field of rapid detection technology for broken yarn in a doubling machine, specifically a rapid detection alarm device for broken yarn in a doubling machine. Background Technology

[0002] When twisting and feeding yarn, the yarn of the doubling machine passes through the yarn storage cylinder, the spindle turntable, and the yarn guiding device, and then the yarn is wound onto the winding device. During the twisting process, due to the contact and wear of the various parts and the tension of the yarn itself, the yarn may break, which needs to be detected and dealt with in time.

[0003] For example, Chinese Patent CN100434577C discloses a wire breakage detection mechanism for a doubling machine, which includes a needle positioning plate, a needle tube, and a needle slidably inserted into the inner cavity of the needle tube. The needle positioning plate has a conductive element, the lower part of the needle tube passes through the conductive element, and an insulator is provided between the needle tube and the conductive element. A guide notch is opened along the axial direction on the side wall of the needle tube, and the upper part of the needle has an extension arm that extends through the guide notch to the outside of the needle tube. In practical applications, the needle positioning plate is electrically connected to the power supply, and an indicator light can be electrically connected to the needle tube. The yarn passes through the underside of the extension arm to support the needle. When the yarn breaks, the needle loses its support, causing the extension arm to descend to the second working position. This allows the extension arm to contact the needle positioning plate and conduct the circuit, illuminating the indicator light connected to the needle tube. This allows the operator to observe the breakage from a distance without needing to be present at the twisting machine for maintenance. Traditional yarn breakage detection in twisting machines relies mainly on electrical signal detection, which is complex, prone to errors, and difficult to repair when a malfunction occurs. Therefore, a rapid yarn breakage detection alarm device for twisting machines is proposed to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a rapid detection and alarm device for yarn breakage in a doubling machine, which has the advantages of simple principle and accurate detection, and solves the problem of complex principles in traditional methods.

[0006] Preferably, a connecting rod is fixedly installed at the other end of the arm, and one end of the connecting rod is fixedly connected to the outer surface of the turntable. A fixed seat is provided inside the turntable, and the turntable is rotatably connected to the fixed seat. One end of the fixed seat is fixedly connected to the outer surface of the mounting base. A guide groove is provided on the outer surface of the fixed seat, and the guide groove is arc-shaped. A guide rod is inserted into one end of the guide groove, and one end of the guide rod is fixedly connected to the inner wall of the turntable. The arm tilts to one side due to its own weight, causing the turntable to rotate along the fixed seat. At the same time, the guide rod on the inner wall slides against the guide groove.

[0007] Preferably, the arm is a two-section telescopic structure, with an inner frame inside one end of the arm, and the arm is slidably connected to the inner frame. The arm length can be adjusted by sliding one end of the arm along the inner frame.

[0008] Preferably, a knob is provided on the outer surface of the top end of the other end of the machine arm, and the knob is threadedly connected to the outer surface of the machine arm. Several slots are provided on the outer surface of the top end of the inner frame, and the bottom end of the inner frame matches the slots.

[0009] (III) Beneficial Effects Compared with the prior art, this utility model provides a rapid detection and alarm device for yarn breakage on a doubling machine, which has the following beneficial effects: The machine arm is supported by the tension of the yarn as it passes around the guide wheel. When the yarn breaks, the machine arm loses its support and falls to one side due to its own weight. This causes the turntable to rotate along the fixed base. At the same time, the guide rod on the inner wall slides against the guide groove, and the protrusion on the surface of the turntable rotates downwards. This causes the push-button switch on the top of the alarm to be pressed, triggering the alarm and alerting the worker to take action. It is a relatively simple process. Attached Figure Description

[0012] 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.

[0013] Please see Figure 1-4 The present invention provides the following technical solution: a quick detection alarm device for broken yarn of a twisting machine, including a mounting base 1, an alarm 11 fixedly mounted on the outer surface of the mounting base 1, a turntable 2 rotatably mounted on the outer surface of the mounting base 1 above the alarm 11, a protrusion 21 integrally provided on the bottom outer surface of the turntable 2, and a push-button switch 12 provided on the top outer surface of the alarm 11. In this embodiment, a connecting rod 32 is fixedly installed at the other end of the robotic arm 3, and one end of the connecting rod 32 is fixedly connected to the outer surface of the turntable 2. A fixed seat 22 is provided inside the turntable 2, and the turntable 2 is rotatably connected to the fixed seat 22. One end of the fixed seat 22 is fixedly connected to the outer surface of the mounting base 1. A guide groove 23 is provided on the outer surface of the fixed seat 22, and the guide groove 23 is arc-shaped. A guide rod 24 is inserted into one end of the guide groove 23, and one end of the guide rod 24 is fixedly connected to the inner wall of the turntable 2. The robotic arm 3 tilts to one side due to its own weight, causing the turntable 2 to rotate along the fixed seat 22. At the same time, the guide rod 24 on the inner wall slides against the guide groove 23. In this embodiment, the robotic arm 3 is set on the outer surface of the turntable 2. A guide wheel 31 is installed on the outer surface of one end of the robotic arm 3. The robotic arm 3 is a two-section telescopic structure. An inner frame 34 is provided inside one end of the robotic arm 3, and one end of the robotic arm 3 is slidably connected to the inner frame 34. One end of the robotic arm 35 is slidably pulled along the inner frame 34 to adjust the length of the robotic arm 35.

[0014] Among them, a knob 33 is provided on the outer surface of the top end of the other end of the arm 3, and the knob 33 is threadedly connected to the outer surface of the arm 3. Several slots 35 are opened on the outer surface of the top end of the inner frame 34, and the bottom end of the inner frame 34 matches the slots 35. When adjusting, first rotate the knob 33 so that one end of the knob 33 disengages from the slot 35 of the inner frame 34, thereby releasing the restriction between the inner frame 34 and the arm 35.

[0015] The working principle of this embodiment is as follows: After the yarn is twisted, it passes around the guide wheel 31. The tension of the yarn itself is used to lift the machine arm 3 upward for support. When the yarn breaks, the machine arm 3 loses support and falls to one side due to its own weight. This causes the turntable 2 to rotate along the fixed base 22. At the same time, the guide rod 24 on the inner wall slides against the guide groove 23. The protrusion 21 on the surface of the turntable 2 rotates downward and presses the push-button switch 12 on the top of the alarm 11, triggering the alarm and reminding the worker to handle the situation. The length of the machine arm 3 can be adjusted according to the usage. When adjusting, first turn the knob 33 so that one end of the knob 33 disengages from the slot 35 of the inner frame 34, thereby releasing the limit between the inner frame 34 and the machine arm 35. Then, slide one end of the machine arm 35 along the inner frame 34 to adjust the length of the machine arm 35. After adjustment, reset the knob 33 and insert it into the corresponding slot 35 for limit fixation.
