Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of high-speed stranding machines, specifically a wire breakage alarm structure for a high-speed stranding machine. Background Technology
[0002] High-speed stranding machines are mechanical devices used to strand multiple metal wires or fiber wires together. They are widely used in industries such as wire and cable, communication cables, and electronic wires. During the stranding process, wire breakage is a common problem, which not only affects production efficiency but may also lead to a decline in product quality. Therefore, a wire breakage alarm structure is particularly important in high-speed stranding machines.
[0003] The existing wire breakage alarm structure of high-speed stranding machines has the following main shortcomings:
[0004] In existing high-speed stranding machines, the breakage alarm system relies on manual monitoring of the strand cores for breakage. However, human error and fatigue are inevitable, making it difficult to maintain a high level of concentration to monitor the status of each strand at all times. Furthermore, using a single type of sensor can lead to misjudgments or missed detections if the sensor itself malfunctions or is affected by external interference such as dust affecting light propagation. This makes it impossible to accurately and promptly detect breakages. Moreover, even when a breakage alarm is detected, it is difficult to accurately pinpoint which strand has broken. When multiple strands are stranded simultaneously, operators cannot quickly determine the specific location of the problem and need to spend considerable time and effort troubleshooting. This increases machine downtime and impacts production efficiency. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a wire breakage alarm structure for a high-speed stranding machine. It aims to solve the problem that the existing wire breakage alarm structure of a high-speed stranding machine relies on a single type of sensor for monitoring, which is prone to misjudgment or missed judgment, cannot accurately and timely detect wire breakage, and is difficult to accurately identify which strand is broken, resulting in the need to spend more time and effort to troubleshoot, thus affecting production efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire breakage alarm structure for a high-speed stranding machine, comprising a frame, wherein six first wire feeding frames are arranged in a ring at the center of the front end face of the frame, and each of the six first wire feeding frames is provided with a wire feeding breakage structure at the center of the front end face, and a wire breakage alarm structure is provided at the center of the inside of the wire feeding breakage structure.
[0007] The six wire feeding and breaking structures include six second wire feeding frames, which are respectively located at the center of the front end face of the six first wire feeding frames. Each of the six second wire feeding frames has a first wire threading groove at its inner center and a sleeve at the center of its inner wall.
[0008] As a further embodiment of this utility model: each of the six second wire feeding frames has a wire hole at the center of its front end face and the center of its rear end face; each of the six second wire feeding frames has four connecting rods arranged in a rectangular pattern on its front end face; and all twenty-four connecting rods are inclined.
[0009] As a further embodiment of this utility model: each of the six sleeves is slidably connected to an inner tube at its center, and each of the six inner tubes is fixedly connected to an elastic block at one end. Each of the six elastic blocks is provided with a third threading groove at the center of its front end face.
[0010] As a further embodiment of this utility model: each of the twenty-four connecting rods at the front end of the six second wire feeding frames is provided with a detection frame, and a second wire threading groove is provided at the center of the interior of the six detection frames.
[0011] As a further embodiment of this utility model: the wire breakage alarm structure includes six touch sensors, which are respectively disposed at the center of the inner wall of the six second wire feeding frames. Six buzzers are arranged in a ring at the center of the rear end face of the frame, and a processing controller is disposed at the center of the rear end face of the frame.
[0012] As a further embodiment of this utility model: each of the six first wire feeding frames is provided with a wire feeding groove at its center, and each of the six wire feeding grooves is provided with a wire wheel at its center.
[0013] As a further embodiment of this utility model: fiber optic sensors are provided inside the six second wire-threading slots at the center of the upper and lower inner walls of the six detection frames.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model employs a dual detection method, utilizing both fiber optic sensors and touch sensors, to detect cable breaks. The fiber optic sensor determines cable breakage by monitoring changes in light propagation, while the touch sensor triggers detection based on changes in cable tension causing shifts in the position of elastic components. This dual-protection mechanism improves the accuracy of cable breakage detection and reduces false alarms. Once either the fiber optic sensor or the touch sensor detects a cable breakage signal, the processing controller receives the signal and quickly activates a buzzer to sound an alarm, promptly notifying the operator. This effectively avoids production problems caused by missed detections, reduces production downtime due to cable breaks, and improves the overall production efficiency of the high-speed stranding machine.
[0016] 2. This utility model, through the rectangular arrangement and inclined setting of connecting rods, and the cooperation of sleeves and inner tubes to connect elastic blocks, makes the cable more orderly and forms a reasonable tension distribution environment during transmission, reducing the risk of wire breakage caused by unreasonable cable layout. The setting of numerous wire slots, including the first, second, and third wire slots and wire holes, optimizes the cable routing method, allowing the cable to pass through each component stably and orderly from the wire release slot to the stranding system, better ensuring the synchronization and stability of each strand during transmission, thereby improving the stranding quality and fundamentally reducing the probability of wire breakage caused by messy routing and uneven tension.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] like Figures 1-4 As shown, this utility model provides a technical solution:
[0024] A wire breakage alarm structure for a high-speed stranding machine includes:
[0025] The frame 1 has six first wire feeding frames 2 arranged in a ring at the center of its front end face. Each of the six first wire feeding frames 2 has a wire feeding groove 3 at its center, and each of the six wire feeding grooves 3 has a wire reel 4 at its center. Each of the six first wire feeding frames 2 has a wire feeding break structure 5 at its center of its front end face. Each of the six wire feeding break structures 5 includes six second wire feeding frames 501, which are respectively located at the center of the front end face of the six first wire feeding frames 2. Each of the six second wire feeding frames 501 has a first wire threading groove 502 at its center of its center, and each of the six second wire feeding frames 501 has a wire hole 503 at the center of both its front and rear ends. Each of the six second wire feeding frames 501 has four connecting rods 504 arranged in a rectangular shape on its front end face. All twenty-four connecting rods 504 are inclined. Each of the six second wire feeding frames 501 has a sleeve 507 at the center of its inner wall. Each of the six sleeves 507 has an inner tube 508 slidably connected to its center. Each of the six inner tubes 508 has an elastic block 509 fixedly connected to one end. Each of the six elastic blocks 509 has a third wire-passing groove 510 at the center of its front end face. Each of the six second wire feeding frames 501 has a detection frame 505 at the front end face of its twenty-four connecting rods 504. Each of the six detection frames 505 has a second wire-passing groove 506 at the center of its center.
[0026] The wire on the reel 4 is led out from the wire feeding groove 3 inside the first wire feeding frame 2, passes through the first wire feeding groove 502 on the second wire feeding frame 501, then passes through the wire holes 503 on the front and rear faces of the second wire feeding frame 501, then passes through the second wire feeding groove 506 on the detection frame 505 at the front end of the connecting rod 504, and then continues to be transmitted through the third wire feeding groove 510 on the elastic block 509 at the end of the inner tube 508 that is slidably connected inside the sleeve 507.
[0027] The wire breakage alarm structure 6 is located at the center of the wire laying structure 5. The wire breakage alarm structure 6 includes six touch sensors 601, which are respectively located at the center of the lower inner wall of the six second wire laying frames 501. Six buzzers 603 are arranged in a ring at the center of the rear end face of the frame 1. A processing controller 604 is located at the center of the rear end face of the frame 1. Fiber optic sensors 602 are installed inside the six second wire threading grooves 506 at the center of the upper and lower inner walls of the six detection frames 505.
[0028] When electrical wires pass through these locations normally, the reflection and refraction of light are within normal limits. If a wire breaks at any point, the propagation of light changes. The fiber optic sensor 602 at the corresponding location detects this change and sends an electrical signal to the processing controller 604. When the wire is under normal tension, the inner tube 508 is in a normal position within the sleeve 507, and the front end of the elastic block 509 is in a certain position. When the wire breaks, the tension disappears, and the inner tube 508 moves under the influence of elastic force or gravity, causing the elastic block 509 to... The position of the third wire guide 510 at the front end changes, thus no longer blocking the touch sensor 601. The touch sensor 601 is triggered and sends an electrical signal to the processing controller 604. After receiving the wire breakage signal from the fiber optic sensor 602 or the touch sensor 601, the processing controller 604 quickly analyzes and processes these signals. After determining that a wire breakage has indeed occurred, the processing controller 604 drives the corresponding buzzer 603 to sound an alarm, reminding the operator that a wire breakage has occurred so that timely measures can be taken for repair and handling to avoid producing defective products.
[0029] The working principle of this utility model is as follows: The wire to be twisted is wound on the wire wheel 4 and placed in the wire feeding groove 3 inside the first wire feeding frame 2. As the twisting machine is started, the wire feeding process begins. The wire is drawn out from the wire feeding groove 3 and enters the first wire feeding groove 502 of the second wire feeding frame 501. The wire passes through the first wire feeding groove 502 in an orderly manner to ensure the stability of the wire during transmission. Then, the wire passes through the wire hole 503 at the center of the front and rear faces of the second wire feeding frame 501. After passing through the wire hole 503, the wire is transmitted to the third wire feeding groove 510 on the elastic block 509 at the end of the inner tube 508, which is slidably connected inside the sleeve 507. When the wire is under normal tension, the position of the inner tube 508 inside the sleeve 507 is fixed, and the front end of the elastic block 509 is also in a normal position, so it will not trigger the touch sensor 601. The wire passes through the second wire feeding groove 506 on the detection frame 505 at the front end of the connecting rod 504, which is arranged in a rectangular shape and is inclined.
[0030] During this process, the fiber optic sensors 602, located at the center of the upper and lower inner walls of the detection frame 505 and inside the second wire-passing groove 506, begin to function. Since the wire normally blocks light, causing reflection and refraction of light to occur in a specific state, the fiber optic sensors 602 can detect this state and thus determine that the wire is in a normal transmission state. After the above transmission process, the multiple strands enter the stranding system and are stranded according to a specific stranding method. This process requires ensuring the synchronous and stable transmission of each strand. Under normal operating conditions throughout the entire workflow, the wire tension ensures the relatively stable position of the inner tube 508 within the sleeve 507. The elastic block 509 will not touch the touch sensor 601 located at the center of the inner wall of the second wire feeding frame 501, and the entire system is in a stable working state. At the same time, the fiber optic sensor 602 monitors the changes in light in the transmission line in real time. Due to the presence of the wire, the light is stably in a specific state, and the fiber optic sensor 602 will not emit abnormal signals. Once the wire breaks, the tension disappears, and the inner tube 508 will move under its own elasticity or gravity, causing the position of the third wire feeding groove 510 at the front end of the elastic block 509 to change, thereby triggering the touch sensor 601. The touch sensor 601 will also transmit an electrical signal to the processing controller 604.
[0031] When a wire breaks at a certain point, the propagation of light at that location immediately changes. When the light that was previously blocked by the wire is no longer blocked, the fiber optic sensor 602 detects the change in light and sends the detected electrical signal to the processing controller 604. After receiving the wire break signal from the fiber optic sensor 602 or the touch sensor 601, the processing controller 604 quickly analyzes and processes these signals. After determining that a wire break has occurred, the processing controller 604 drives the corresponding buzzer 603 to sound an alarm. The alarm can promptly remind the operator that a wire break has occurred, prompting the operator to take appropriate measures for repair and troubleshooting to ensure that production can resume normally as soon as possible, while avoiding the production of more defective products and reducing production losses.
[0032] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
