Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a spinning spindle abnormal vibration triggering device that can efficiently guide the yarn. Background Technology

[0002] During the production of nylon 6 filament, filament drift frequently occurs, meaning that one or more filaments from the molten stream ejected from the spinneret break 5-10 cm away from the spinneret. In severe cases, such as multiple filaments breaking, the entire bundle may break. In less severe cases, the broken ends of the filaments are blown out of the main bundle by the side airflow and scattered outside. This type of broken filament drift is easy to detect and can be handled by operators during inspections. However, some filament varieties have a large number of spinneret holes, which can only be addressed by the spinneret... Only broken filaments on the outer periphery of the spinneret are blown out. Broken filaments in the central area of ​​the spinneret are blocked and cannot drift away from the filament bundle. At this point, the broken filament in the center is instantly carried into the subsequent process by the main filament bundle, and it continues to coil, potentially forming a bundle without breaking again. This phenomenon is instantaneous. Furthermore, in the case of multi-hole spinnerets, some varieties have as many as 70-136 holes. A single broken filament or a small number of broken filaments continuing to travel and merging into the main filament bundle is extremely difficult to detect, remove, or intervene with. This results in defects in the spindle cake at that location, especially within the inner layer of the cake and the inner side of the filament bundle, making quality inspection very difficult. With current methods, it is impossible to detect a small number of broken filaments in the center of the cake. When these defective silk bundles flow into downstream users, especially garment manufacturers, the users need to stretch the silk bundles and weave them into fabric. The abnormal central silk threads are prone to unwinding, breakage, or fuzzing, making the entire section of fabric unusable and causing losses in both upstream and downstream processes of the textile manufacturing process.

[0003] Based on this, this utility model designs a spinning spindle abnormal vibration triggering device that can efficiently guide the yarn, in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency spinning spindle abnormal vibration triggering device. During the spinning process, any broken yarn will cause an abnormal yarn bundle diameter. When the abnormal yarn passes through the guide hook, it will cause abnormal vibration. This device utilizes this vibration to detect the vibration of each guide hook and amplifies the abnormal vibration through a vibration transmission rod. This allows for effective detection of broken yarns trapped inside the yarn bundle. An alarm light is used to provide visual warning, and the alarm light and time are recorded simultaneously. This allows for the identification of each abnormal yarn cake and the spinning time, facilitating the removal and re-inspection of abnormal yarns, and effectively improving the yield rate of spun products.

[0005] This invention is achieved as follows: a spinning spindle abnormal vibration triggering device that can efficiently guide the yarn, comprising: Guide rod, connecting rod, detection rod, vibration transmission rod, and warning light; Both the guide rod and the detection rod are horizontally mounted straight rods; The connecting rod is an S-shaped bent rod, and the guide rod and the detection rod are connected by the connecting rod. The detection rod is located on the rear side of the guide rod. The guide rod can be locked to the lower end of the connecting rod in a lateral sliding manner, and the detection rod can also be locked to the upper end of the connecting rod in a lateral sliding manner. The guide rod is provided with multiple guide hooks, which extend out from the front side of the guide rod; The detection rod has multiple detection holes, each of which vertically penetrates the side wall of the detection rod, and each of the detection holes is equipped with a warning light; The lower end of the warning light has a raised electrode point, and the outer wall of the warning light has another electrode. The vibration transmission rod is a rigid long rod, and the lower end of the vibration transmission rod is fitted onto the guide wire hook through a threaded, detachable ring. The upper end of the vibration transmission rod is also provided with an outer contact ring and an inner contact ring. The outer contact ring is sleeved inside the inner contact ring, and the outer contact ring and the inner contact ring are connected as an integral structure. The outer contact ring is non-contactingly placed inside the lower opening of the detection hole, and the inner contact ring is non-contactingly placed outside the electrode point; The electrode points and outer wall electrodes of the warning light are connected by an outer contact ring and an inner contact ring to form a complete circuit.

[0006] Furthermore, rotating rods are provided at both the upper and lower ends of the connecting rod, and each rotating rod is provided with a set screw; The guide rod and the detection rod are respectively inserted into two different rotating rods, and the guide rod and the detection rod are locked to the two different rotating rods by separate set screws; The connecting rod and the rotating rod are locked together by threads.

[0007] Furthermore, the horizontal distance between the detection rod and the guide wire rod is between 5-10 cm; The detection rod is parallel to the guide wire rod, and the detection rod is positioned above the guide wire rod.

[0008] Furthermore, the vibration transmission rod is a single long rod made of spring steel.

[0009] Furthermore, both the inner and outer contact rings are integral circular rings made of spring steel, and the inner and outer contact rings are fixedly connected. The outer diameter of the outer contact ring is smaller than the diameter of the detection hole, and the diameter difference is 1mm; The inner diameter of the inner contact ring is larger than the maximum diameter of the electrode point, and the diameter difference does not exceed 1 mm. The plane where the inner contact ring is located is within the height coverage area of ​​the electrode point.

[0010] The beneficial effects of this utility model are: 1. By adding a vibration transmission rod, this utility model forms a vibration trigger between the guide wire hook and the warning light. Once the traveling wire on the guide wire hook vibrates abnormally, the vibration transmission rod will receive the vibration. Since the vibration transmission rod is made of spring steel, after receiving the vibration, the far end will produce a larger swing amplitude, thereby causing abnormal vibration, thus effectively identifying and forming feedback on abnormal vibration. 2. The vibration trigger end of this device is equipped with an inner contact ring and an outer contact ring, which makes the positive and negative poles of the warning light electrically connected. The warning light is also connected to other external circuit systems and spinning monitoring systems, so that each vibration can be recorded and alerted, effectively tracing abnormal yarns and facilitating subsequent manual screening. This also allows for the detection of broken yarns in the center of the spinning yarn bundle. 3. The guide rod and the detection rod of this device are separate and spaced far apart. It is also equipped with a rotating rod and a set screw. The height position between the guide rod and the detection rod can be adjusted by rotating the rod. The horizontal swing position between the guide rod and the detection rod can also be adjusted by threading. It is convenient to use. Attached Figure Description

Detailed Implementation

[0014] Please see Figures 1 to 5As shown, this utility model provides a spinning spindle position abnormal vibration triggering device that can efficiently guide the yarn. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] In a specific embodiment of the technical solution of this utility model: It includes a guide rod 1, a connecting rod 2, a detection rod 3, a vibration transmission rod 4, and a warning light 5; Both the guide rod 1 and the detection rod 3 are horizontally mounted straight rods; The connecting rod 2 is an S-shaped bent rod. The guide rod 1 and the detection rod 3 are connected by the connecting rod 2. The detection rod 3 is located on the rear side of the guide rod 1. The guide rod 1 can be locked to the lower end of the connecting rod 2 by sliding laterally, and the detection rod 3 can also be locked to the upper end of the connecting rod 2 by sliding laterally. Both of them slide horizontally, which makes it easy to adjust the lateral extension position of the guide rod 1 and the detection rod 3, thereby flexibly adapting to the guiding position and guiding path of the wire, and making it easy for the wire to pass through. Multiple guide hooks 11 are provided on the guide rod 1. The guide hooks 11 extend out of the front side of the guide rod 1, and the straight rod of the rear end of the guide hook 11 extends out of the rear end of the guide rod 1. This type of guide rod needs to be locked to the guide rod 1 by a set screw 22. This structure is the commonly used installation structure of the existing guide hook 1 and has been widely used. The connecting rod 2 has rotating rods 21 at both the upper and lower ends, and each rotating rod 21 is equipped with a set screw 22; The guide rod 1 and the detection rod 3 are respectively inserted into two different rotating rods 21, and both the guide rod 1 and the detection rod 3 are locked to the two different rotating rods 21 by separate set screws 22. The connecting rod 2 and the rotating rod 21 are locked together by threads. Nuts and washers can also be added to change the height distance between the guide rod 1 and the detection rod 3. When in use, both the guide rod 1 and the detection rod 3 need to be locked together with the rotating rod 21.

[0016] The horizontal distance between the detection rod 3 and the guide rod 1 is between 5-10cm, so that the detection rod 3 avoids the position of the wire and avoids the detection rod 3 from obstructing the progress of the wire. The detection rod 3 is parallel to the guide rod 1, and the detection rod 3 is above the guide rod 1, so as to ensure the travel position of the wire and avoid interference between the wire and the detection rod 3. It is also necessary to avoid the wire from contacting and affecting each other with the vibration transmission rod 4. Vibration can only be generated through the guide hook 11 to the vibration transmission rod 4.

[0017] Multiple detection holes 31 are opened on the detection rod 3. Each detection hole 31 vertically penetrates the side wall of the detection rod 3. A warning light 5 is installed on each detection hole 31. The lower end of the warning light 5 is a raised electrode point 51. The lower end of the warning light 5 is an electric contact screw 52. The electric contact screw 52 is stably installed in the detection hole 31 by threads. The outer wall of the electric contact screw 52 is another electrode, which is generally the negative electrode. This electrode structure is a common structure for spiral bulbs. The vibration transmission rod 4 is a rigid long rod made of spring steel. It can maintain a certain frequency of vibration when subjected to abnormal vibration and will not immediately return to its original position. When the wire is moving normally, it will experience stable and small vibrations. After the wire stabilizes, the vibration will disappear and instead generate continuous compressive tension. Therefore, it will not trigger the warning light 5 of this device. The spring rod is actually a thin spring steel wire with high hardness and a certain degree of elasticity. The diameter of the vibration transmission rod 4 is also about 1mm, which has good elasticity. This allows it to transmit the abnormal vibration of the wire passing through the guide hook 11, which is convenient for accurate detection and warning.

[0018] The lower end of the vibration transmission rod 4 is fitted onto the guide wire hook 11 via a threaded, detachable ring. The upper end of the vibration transmission rod 4 is also provided with an outer contact ring 42 and an inner contact ring 41. The outer contact ring 42 is sleeved inside the inner contact ring 41. The outer contact ring 42 and the inner contact ring 41 are connected as an integral structure to form an integral support structure and to form a circuit connection. The outer contact ring 42 is non-contactly placed inside the lower opening of the detection hole 31, and the inner contact ring 41 is non-contactly placed outside the electrode point 51. The lower end of the warning light 5 is an electric contact screw 52, ​​which is used to screw and lock into the detection hole 31. The electric contact screw 52 has the same threaded connector structure as the common lamp, and the center point is the positive electrode point 51 of the electric contact. The electrode point 51 of the warning light 5 and the outer wall electrode are connected through the outer contact ring 42 and the inner contact ring 41 to form a complete circuit. Each warning light 5 is connected to an external controller and data monitoring system to ensure that the number of times each warning light 5 is powered on is recorded and alarmed. This data recording of the starting circuit has become a common function in the spinning traceability system. This device can be added to and integrated into this system. This device only plays a warning detection and triggering role for abnormal yarns.

[0019] Both the inner contact ring 41 and the outer contact ring 42 are integral circular rings made of spring steel, and the inner contact ring 41 and the outer contact ring 42 are fixedly connected. The thickness of the inner contact ring 41 and the outer contact ring 42 does not exceed 1mm. The finer wire makes it easier to transmit vibration when connected, ensuring that each abnormal swing can trigger the circuit where the warning light 5 is located. The outer diameter of the outer contact ring 42 is smaller than the diameter of the detection hole 31, and the diameter difference is 1mm; The inner diameter of the inner contact ring 41 is larger than the maximum diameter of the electrode point 51, and the diameter difference does not exceed 1mm. The plane where the inner contact ring 41 is located is within the height coverage range of the electrode point 51. The warning light 5 and the inner contact ring 41 and outer contact ring 42 of the vibration transmission rod 4 form a nested relationship with gaps. When vibration occurs, the positive and negative poles of the warning light 5 are connected to the external circuit through the inner contact ring 41 and outer contact ring 42. Moreover, each warning light 5 has a separate detection circuit, or it can be the same detection circuit, but the microcontroller identifies different warning lights 5, so that different abnormal conditions are recorded for each different warning light 5.

[0020] A better solution is to install a trigger switch in the external circuit of the warning light 5 device. Once triggered, the light will remain constantly lit. Generally, this type of switch is a trigger switch, which is usually controlled by a circuit or PLC controller, such as a delay switch. The delay can be set to 1 hour or even longer. This application does not protect or limit the circuit and microcontroller, nor does it make any requirements on whether the light is continuously lit. It simply provides a better solution. The device itself only needs the warning light 5 to be triggered and started.

[0021] It should be noted that: Currently, there is no way to accurately detect or judge the breakage of a single filament in the center of the filament bundle, especially for high-speed filaments, which are impossible to detect even with the naked eye. Moreover, dozens of filaments are spinning simultaneously in each spinning machine, making it impossible to observe for a long time. Therefore, during the spinning process, if thick or thin filaments or a single broken filament is found stuck in the middle of the filament bundle, this device is completely unable to make a judgment.

[0022] This device has no impact on the spinning speed of the yarn, and can detect the breakage of individual yarns in a timely manner, making spinning more efficient. It can detect abnormal yarn cakes, making yarn spinning more efficient. No additional detection methods are needed, and there is no need to unfold the yarn for individual inspection. Yarn spinning is more stable and efficient, and product quality can be guaranteed.

[0023] When a broken filament occurs in the middle of the filament bundle, the bundle will also change, possibly clumping, thickening, or twisting. Each abnormal filament will be guided and constrained by the guide hook 11 during its journey. When the filament travels at high speed under high tension through the guide hook 11, it will generate obvious abnormal vibration. This device utilizes this situation to detect the vibration of each guide hook 11. The vibration of the guide hook 11 is transmitted through the elasticity of the vibration transmission rod 4, and the vibration at the guide hook 11 is detected and illuminated. At the same time, the activation time of the warning light 5 is recorded, thereby identifying each abnormal filament and tracing its source. The abnormal spinning time is also marked, which facilitates the picking out of abnormal filaments and re-pointing the inspection, effectively improving the yield rate.

[0024] When this utility model is in use, if there is an abnormality in the upstream thread, the thread will move very fast when passing through the guide hook 11, and the guide hook 11 and subsequent processes will form a stable tension on the thread. At this time, when the thread bulges abnormally, it will cause the guide hook 11 to vibrate, and the vibration amplitude will be obvious.

[0025] The vibration transmission rod 4 transmits the vibration of the guide wire hook 11 to the inner contact ring 41 and the outer contact ring 42 at the far end. When the inner contact ring 41 and the outer contact ring 42 swing, the inner contact ring 41 will come into contact with the electrode point 51, while the outer contact ring 42 will come into contact with the inner wall of the detection hole 31, thereby electrically connecting with the outer wall electrode of the electric contact screw 52 at the lower end of the warning light 5, thus forming a complete circuit. At this time, the warning light 5 will start to issue a warning, and the entire system will receive the abnormal information and record the time point. This device is only a triggering method. The subsequent circuit connection of the warning light 5 can also be set with a microcontroller or control system to make the warning light 5 continuously illuminated. It can also record and trace the start and stop of the warning light 5. This circuit system is not included in this device. This device only provides a triggering structure for wire abnormality.

Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
