Description

Technical Field

[0001] The present invention relates to the technical field of winding heads, and more specifically, to an anti-tangling and broken wire alarm mechanism for a winding head. Background Art

[0002] A winding head is a working unit in a spinning machine for winding silk threads. During the winding production process, the entanglement and breakage of silk threads are common problems. When a silk thread breaks, if it cannot be detected and processed in time, it will cause production interruption and affect production efficiency. Summary of the Invention

[0003] The present invention provides an anti-tangling and broken wire alarm mechanism for a winding head, which can overcome certain or some defects of the prior art.

[0004] An anti-tangling and broken wire alarm mechanism for a winding head according to the present invention includes a mechanism main body for being arranged at a spinning machine and cooperating with the winding head. The mechanism main body includes a housing and an alarm component arranged at the housing. A wire arranging component is arranged at the housing. The wire arranging component includes a fixed arm and a rotating arm hinged to one end of the fixed arm. A wire guiding member for the silk thread to pass through is arranged at the other end of the rotating arm. A tension spring is arranged between the fixed arm and the rotating arm, and the tension spring is used to provide an elastic force for keeping the fixed arm and the rotating arm in contact with each other. The alarm component includes a controller arranged at the housing, a first contact arranged at the wire guiding member, and a second contact arranged at the fixed arm and cooperating with the first contact. The controller is used to send an alarm instruction to the terminal when the first contact is connected to the second contact.

[0005] Through the setting of the wire arranging component, the silk thread can be guided to wind according to a predetermined path, so that the silk thread is arranged in an orderly manner at the winding head, avoiding the chaotic entanglement of the silk thread, ensuring the smooth progress of the winding process, and cooperating with the setting of the alarm component. When the silk thread is normally wound, due to the pulling force during the winding of the silk thread, the wire guiding member maintains a relatively stable position along with the movement of the silk thread. As shown in Figure 5 As shown, the first contact and the second contact are in a separated state. At this time, the first contact and the second contact are not connected, and the controller does not work. When the silk thread breaks, the pulling force originally acting on the wire guiding member disappears. Under the action of the elastic force of the tension spring, the rotating arm will rotate, so that the first contact is connected to the second contact. At this time, the controller detects the signal that the first contact is connected to the second contact and sends an alarm instruction to the terminal, thereby realizing the real-time monitoring and timely alarm of the silk thread breakage situation, shortening the production stagnation time caused by the broken wire, and thus improving the overall efficiency of the spinning production. Compared with the prior art, the present disclosure utilizes the pulling force generated between the silk thread and the wire guiding member during the winding process and cooperates with the setting of the alarm component, so that when a broken wire occurs, the first contact and the second contact can be instantaneously contacted and connected, and an alarm instruction is sent through the controller. The structure is simple, the alarm response is rapid and reliable, and the production cost is low.

[0006] It is understandable that the setting of the tension spring and the rotating arm enables the silk thread to enter the winding head of the subsequent winding at a more appropriate angle, avoiding unnecessary tension changes of the silk thread due to unreasonable path.

[0007] Preferably, the wire guiding member includes a mounting seat with an upward opening, a mounting ring for the silk thread to penetrate is formed at the mounting seat, a cooperating member cooperating with the mounting seat is formed at the fixed arm, and a penetrating interval for mounting the silk thread is formed between the cooperating member and the mounting seat.

[0008] Through the setting of the mounting ring, a clear penetration channel is provided for the silk thread, avoiding situations such as deviation, distortion, and falling off of the silk thread.

[0009] It is understandable that the setting of the penetrating interval enables the cooperating member and the mounting seat not to interfere with the normal movement of the silk thread when the silk thread presses down on the mounting seat.

[0010] Preferably, a notch is formed at one end of the mounting seat away from the rotating arm, and a second wire guiding roller is rotatably provided at the notch.

[0011] Through the setting of the second wire guiding roller, the friction between the silk thread and the wire guiding member is reduced, and the risks of silk thread wear and breakage are reduced.

[0012] Preferably, a convex portion protruding downward is formed at the bottom wall of the cooperating member, the first contact is provided at the bottom wall of the convex portion, a concave portion recessed downward is formed at the top wall of the mounting seat, and the second contact is provided at the bottom wall of the concave portion.

[0013] Through the above structure, precise positioning is provided for the first contact and the second contact, improving the cooperation accuracy between the first contact and the second contact.

[0014] Preferably, a through groove is formed at the top wall of the fixed arm, a first wire guiding roller is rotatably provided at the through groove, and a pressing roller assembly cooperating with the first wire guiding roller is slidably provided in the fixed arm; wherein, both the first wire guiding roller and the pressing roller assembly are located obliquely above the second wire guiding roller on the side close to the housing.

[0015] The pressing roller assembly is slidably arranged in the fixed arm and cooperates with the first wire guiding roller. By adjusting the distance and pressure between the pressing roller assembly and the first wire guiding roller, the tension of the silk thread can be effectively adjusted. When the tension of the silk thread is too large, the pressing force can be appropriately reduced; when the tension of the silk thread is too small, the pressing force is increased, so as to keep the silk thread at an appropriate tension during the winding process and ensure the winding quality.

[0016] Preferably, a sliding groove is formed at the inner wall of the fixed arm, the pressing roller assembly includes a slider slidably arranged in the sliding groove, a pressing roller is rotatably provided at the slider, and a spring is provided between the fixed arm and the slider, and the spring is used to provide an elastic force for keeping the slider pressing towards the first wire guiding roller.

[0017] During the wire winding process, the wire tension may fluctuate due to the operation of the equipment and the movement of the wire. The pressure roller assembly can buffer this tension change to a certain extent. When the wire tension suddenly increases, the pressure roller assembly can release part of the tension through the spring; when the tension decreases, the spring can press the pressure roller toward the first wire roller to play a tensioning role. This adaptive adjustment method can keep a relatively stable tension of the wire during the winding process, which is beneficial to improving the winding quality.

[0018] It is understandable that when the wire is broken, the spring can press the pressing roller against the first wire roller, thereby clamping the broken wire to prevent the broken wire from interfering with the equipment.

[0019] Preferably, the first contact and the second contact are electrically connected to the controller via wires respectively.

[0020] The wire connects the first contact, the second contact and the controller to form a complete electrical circuit. When the contacts are connected, current can flow in the circuit. After the controller detects the current signal, it sends an alarm command to the terminal.

[0021] Preferably, a driving assembly is provided at the housing, and the cable arranging assembly is provided at the moving end of the driving assembly, and the driving assembly is used to drive the cable arranging assembly to reciprocate along the length direction of the winding head.

[0022] Through the above structure, the silk threads can be evenly distributed on the winding head. The uniform wire arrangement makes the appearance of the wound silk threads neat and tight, reduces the gaps and looseness between the silk threads, and improves the overall quality of the silk thread winding.

[0023] Preferably, a tension rod is provided at the shell, and the tension rod has a tension portion bent from the middle to both ends, and the tension portion is located obliquely above the first wire roller on one side close to the shell.

[0024] The above structure ensures that when the cable arrangement assembly reciprocates along the length direction of the winding head, the wire can be wound evenly at both ends of the winding head, thereby avoiding uneven tension caused by angle deviation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it. Example 1

[0028] See also Figures 1 - 5 The present embodiment provides a winding head anti-winding wire break alarm mechanism, which includes a mechanism body 100 for being arranged at a spinning machine and cooperating with a winding head, the mechanism body 100 includes a shell 110 and an alarm assembly arranged at the shell 110, a wire arrangement assembly 130 is arranged at the shell 110, the wire arrangement assembly 130 includes a fixed arm 210 and a rotating arm 220 with one end hinged at the fixed arm 210, a wire guide 230 for the wire to pass through is arranged at the other end of the rotating arm 220, a tension spring 240 is arranged between the fixed arm 210 and the rotating arm 220, and the tension spring 240 is used to provide an elastic force to keep the fixed arm 210 and the rotating arm 220 in close contact; The alarm component includes a controller disposed at the shell 110, a first contact 341 disposed at the guide wire 230, and a second contact 510 disposed at the fixed arm 210 and cooperating with the first contact 341. The controller is used to send an alarm instruction to the terminal when the first contact 341 is connected to the second contact 510.

[0029] The winding head anti-winding wire break alarm mechanism disclosed in the present invention can guide the wire to be wound along a predetermined path through the arrangement of the wire arrangement component 130, so that the wire is arranged in an orderly manner at the winding head, avoiding the chaotic winding of the wire, ensuring the smooth progress of the winding process, and in conjunction with the arrangement of the alarm component, when the wire is wound normally, due to the tension of the wire during winding, the wire guide 230 maintains a relatively stable position with the movement of the wire, as shown in Figure 5As shown, the first contact 341 and the second contact 510 are in a separated state. At this time, the first contact 341 and the second contact 510 are not connected, and the controller does not work. When the wire breaks, the pressure originally acting on the wire guide 230 disappears. Under the action of the elastic force of the tension spring 240, the rotating arm 220 rotates, so that the first contact 341 is connected with the second contact 510. At this time, the controller detects the signal that the first contact 341 is connected with the second contact 510, and sends an alarm instruction to the terminal, thereby realizing real-time monitoring and timely alarm of the wire breakage, shortening the production stagnation time caused by broken wire, and thus improving the overall efficiency of spinning production. Compared with the prior art, by using the tension generated between the wire and the wire guide 230 during the winding process, and cooperating with the setting of the alarm component, when the wire breaks, the first contact 341 and the second contact 510 can be instantly contacted and connected, and the alarm instruction is sent through the controller, which has a simple structure, rapid and reliable alarm response, and low production cost.

[0030] It is understandable that the arrangement of the tension spring 240 and the rotating arm 220 allows the wire to enter the subsequent winding head at a more appropriate angle, thereby avoiding unnecessary tension changes of the wire due to unreasonable paths.

[0031] In this embodiment, the wire guide 230 includes a mounting seat 350 with an opening facing upward, a mounting ring 360 for the wire to pass through is formed at the mounting seat 350, a mating piece 340 mating with the mounting seat 350 is formed at the fixed arm 210, and a through-passing area for the wire to be installed is formed between the mating piece 340 and the mounting seat 350.

[0032] The 360-degree setting of the mounting ring provides a clear through-channel for the wire to prevent the wire from being deflected, twisted, or falling off.

[0033] It can be understood that the setting of the through-interval ensures that when the thread presses down the mounting seat 350 , the matching piece 340 and the mounting seat 350 will not interfere with the normal movement of the thread.

[0034] In this embodiment, a notch is formed at one end of the mounting seat 350 away from the rotating arm 220 , and a second wire roller 370 is rotatably disposed at the notch.

[0035] By disposing the second wire roller 370, the friction between the wire and the wire guide 230 is reduced, thereby reducing the risk of wire wear and breakage.

[0036] In this embodiment, a convex portion protruding downward is formed at the bottom wall of the mating piece 340, and the first contact 341 is arranged at the bottom wall of the convex portion. A concave portion recessed downward is formed at the top wall of the mounting seat 350, and the second contact 510 is arranged at the bottom wall of the concave portion.

[0037] Through the above structure, accurate positioning is provided for the first contact 341 and the second contact 510, thereby improving the matching accuracy between the first contact 341 and the second contact 510.

[0038] In this embodiment, a through groove 310 is formed at the top wall of the fixed arm 210, and a first wire roller 320 is rotatably provided at the through groove 310. A clamping roller assembly 330 that cooperates with the first wire roller 320 is slidably provided in the fixed arm 210; wherein the first wire roller 320 and the clamping roller assembly 330 are both located obliquely above the second wire roller 370 on the side close to the shell 110.

[0039] The pressure roller assembly 330 can be slidably disposed in the fixed arm 210 and cooperate with the first wire roller 320. By adjusting the distance and pressure between the pressure roller assembly 330 and the first wire roller 320, the tension of the wire can be effectively adjusted. When the wire tension is too large, the pressure can be appropriately reduced; when the wire tension is too small, the pressure is increased, so that the wire maintains appropriate tension during the winding process to ensure the winding quality.

[0040] In this embodiment, a slide groove 410 is formed on the inner wall of the fixed arm 210, and the clamping roller assembly 330 includes a slider 420 slidably arranged in the slide groove 410, and a clamping roller 430 is rotatably arranged on the slider 420. A spring 440 is arranged between the fixed arm 210 and the slider 420, and the spring 440 is used to provide an elastic force to keep the slider 420 pressed toward the first wire roller 320.

[0041] During the wire winding process, the wire tension may fluctuate due to the operation of the equipment and the movement of the wire. The pressure roller assembly 330 can buffer this tension change to a certain extent. When the wire tension suddenly increases, the pressure roller assembly 330 can release part of the tension through the spring 440; when the tension decreases, the spring 440 can press the pressure roller 430 toward the first wire roller 320 to play a tensioning role. This adaptive adjustment method can keep a relatively stable tension of the wire during the winding process, which is beneficial to improving the winding quality.

[0042] It is understandable that when the wire is broken, the spring 440 can press the pressing roller 430 against the first wire roller 320, thereby clamping the broken wire to prevent the broken wire from interfering with the equipment.

[0043] In this embodiment, the first contact 341 and the second contact 510 are electrically connected to the controller through wires, respectively.

[0044] The wire connects the first contact 341, the second contact 510 and the controller to form a complete electrical circuit. When the contacts are connected, current can flow in the circuit. After the controller detects the current signal, it sends an alarm instruction to the terminal. Example 2

[0045] See Figure 1 This embodiment also provides a winding head anti-winding wire breakage alarm mechanism, which differs from Embodiment 1 in that a driving component 120 is provided at the shell 110, and a cable arrangement component 130 is provided at the moving end of the driving component 120, and the driving component 120 is used to drive the cable arrangement component 130 to reciprocate along the length direction of the winding head.

[0046] Through the above structure, the silk threads can be evenly distributed on the winding head. The uniform wire arrangement makes the appearance of the wound silk threads neat and tight, reduces the gaps and looseness between the silk threads, and improves the overall quality of the silk thread winding.

[0047] In this embodiment, a tension rod 140 is disposed at the housing 110 . The tension rod 140 has a tension portion bent from the middle to both ends. The tension portion is located obliquely above the first wire roller 320 on the side close to the housing 110 .

[0048] Depend on Figure 1 or Figure 5 It can be seen that when connecting the wire to the winding head, the wire is first laid on the tension portion of the tension rod 140 and then passes through the cable assembly 130 and connected to the winding head to complete the connection of the wire.

[0049] The above structure ensures that when the cable arrangement assembly 130 moves back and forth along the length direction of the winding head, the wire can be wound evenly at both ends of the winding head, thereby avoiding uneven tension caused by angle deviation.
