A wire winding device with a swing arm guide structure and its winding method

Abstract

This invention discloses a wire winding device with a swing arm guide structure and its winding method, belonging to the technical field of winding devices. This invention constructs a three-section swing arm guide structure along the winding path—entry positioning, intermediate pre-tensioning, and exit width limiting—to collaboratively solve the problems of slack rebound and interlayer skipping during the winding of low-rigidity paper rope from three dimensions: path constraint, tension stability, and arrangement accuracy. By forming an enclosed structure with evenly distributed arc-shaped abutment plates around the circumference of the detection ring, and utilizing the essential difference in radial hardness between the moisture-absorbing expansion section and the knotted defect section, the system's equivalent stiffness is designed between the two, achieving automatic identification of flexible over-diameter release and rigid defect triggering. Through dual elastic energy storage elements, the work done during the process of the arc-shaped abutment plates being pushed open is converted into potential energy for temporary storage. This energy is released at the instant the defect section detaches, driving the marker head to eject and complete pigment transfer, achieving temporal self-coupling of detection and marking without sensor intervention, and the marker position is naturally synchronized with the defect section.

Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and specifically to a wire winding device with a swing arm guiding structure and a winding method thereof. Background Art

[0002] Paper ropes are linear flexible materials made from plant fiber paper tapes through twisting or winding. Due to their biodegradable and renewable characteristics, they are widely used in fields such as agricultural product bundling, gift packaging, and horticultural binding as substitutes for traditional plastic tying wires. The winding device for paper ropes is a key equipment at the end of its production line, responsible for orderly winding the continuously produced paper ropes onto a winding cylinder to form a finished roll for use in subsequent packaging stations.

[0003] Existing paper rope winding devices usually adopt a scheme of driving the winding cylinder to rotate by a motor and guiding the wire into the cylinder with a fixed or simple reciprocating wire guiding mechanism. The wire is led out from the wire supply rack and guided to the surface of the winding cylinder through a wire guiding hole or a wire guiding roller, and the traction force generated by the rotation of the winding cylinder continuously winds and binds the wire. Some improved schemes add a tension wheel or a weight type tension compensator on the wire guiding path to cope with the transient mismatch between the wire supply speed and the winding speed. In terms of quality inspection, existing schemes usually use a through-hole ring with a fixed aperture to conduct on-line inspection of the wire. If there is no interference when the wire passes through the through-hole ring, it is judged as qualified; if interference occurs, it triggers a stop alarm.

[0004] However, the above-mentioned winding devices still have the following defects: As a plant fiber twisted product, the radial stiffness and tensile strength of paper ropes are much lower than those of metal wires or chemical fiber wires. The existing wire guiding paths lack a multi-stage constraint design for this low stiffness characteristic. There is no effective radial limit for the suspended section of the wire between the wire supply rack and the winding cylinder, and only the end traction force is relied on to maintain the posture. When the equipment vibrates or the winding speed fluctuates, causing transient changes in tension, the low stiffness paper ropes are extremely prone to radial跳动 and axial偏摆, resulting in layer-to-layer wire jumping and local stacking. More critically, the paper ropes will exhibit local over-diameter phenomena due to moisture absorption and swelling and knotting and splicing during transportation. The two are extremely similar in appearance size characterization (both show a sudden increase in radius), but their physical natures are completely different. Moisture absorption and swelling are reversible flexible deformations (automatically恢复 after drying), and knotting and splicing are irreversible rigid structural defects (which will cause jamming during subsequent automatic unwinding). The existing through-hole ring detection method can only determine "whether it is over-diameter", and its discrimination basis is a size threshold rather than the material mechanics property, and it cannot distinguish the above two types of over-diameters with completely different natures, resulting in either all being cut off, causing a large amount of waste, or all being released, allowing defective products to flow into the subsequent process. Summary of the Invention

[0005] The purpose of this invention is to provide a wire winding device and its winding method with a swing arm guide structure, so as to solve the problems in the prior art where low-stiffness wires such as paper ropes experience slack jumping and interlayer skipping during winding due to the lack of multi-level radial constraints on the conductor path, and the online detection process cannot distinguish between moisture absorption expansion and knotting defects, which are two different types of over-diameter defects, thus leading to misjudgment.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: A wire winding device with a swing arm guide structure includes: a winding table, on which a driving component is installed; a swing arm assembly, which is installed on one side of the winding table, the swing arm assembly including a winding block, on which a detection component is installed; The detection component includes a detection ring mounted on one side of the winding block, and a plurality of evenly distributed feedback components are mounted around the detection ring.

[0007] Preferably, the drive assembly includes a drive block installed in the winding table, a drive disk is installed at the output end of the drive block, and a winding drum is installed on the drive disk.

[0008] Preferably, the winding block is installed on one side of the winding table, and a pressing block is installed on the winding block, and a swing arm is installed at one end of the winding block.

[0009] Preferably, the feedback component includes a feedback cylinder, a slider is slidably connected inside the feedback cylinder, and a pressing rod is installed at the bottom end of the slider.

[0010] Preferably, a limiting block is installed on the inner wall of the feedback cylinder, and the extrusion rod passes through the limiting block and extends to the outer end of the limiting block.

[0011] Preferably, a marking head is installed at the bottom end of the extrusion rod, and an arc-shaped abutment plate is installed at one end of the extrusion rod.

[0012] Preferably, a support ring is installed around the extrusion rod and inside the feedback cylinder, and multiple evenly distributed support bars are installed on the top of the limiting block, with the multiple support bars connected to the support ring.

[0013] Preferably, a compression spring is installed on the inner wall of the feedback cylinder, and one end of the compression spring is connected to the slider.

[0014] Preferably, the spring force exerted by the compression spring on the slider is less than the supporting force exerted by the multiple support bars on the support ring.

[0015] A wire winding method with a swing arm guide structure includes the following steps: S1: Pass the wire through the detection ring and the winding block in sequence, and after being pre-tightened by the pressing block, pass it around the swing arm to fix the end of the wire to the winding drum; S2: Start the drive block, the drive block drives the drive disk to rotate, the drive disk synchronously drives the winding drum to rotate, and the wire begins to be wound up. The swing arm swings back and forth with the winding process to realize wire laying. S3: During the winding process, the wire continuously passes through the detection ring, and the arc-shaped contact plates of multiple feedback components are always in radial contact with the surface of the wire to monitor the radial dimension of the wire in real time. S4: When an over-diameter section appears in the wire, if the over-diameter section is caused by soft expansion due to moisture absorption, then because of its soft material, the radial pressure applied to it by multiple arc-shaped abutment plates will cause it to be locally compressed and deformed, and the arc-shaped abutment plates will not be able to be opened. The extrusion rod will not be displaced, and it will be judged as a harmless section and will not be marked. If the over-diameter section is caused by a knot or overlap, then because of its hard material, it will open the multiple arc-shaped abutment plates radially. S5: After the arc-shaped abutment plate is opened, it drives the extrusion rod to move towards the inside of the feedback cylinder. The extrusion rod pushes the slider to compress the extrusion spring and store the first potential energy. At the same time, the support ring around the extrusion rod overcomes the holding force of multiple support bars and stores the second potential energy. The wire continues to move, causing the hard defect section to slide along the surface of the arc-shaped abutment plate. S6: When the hard defect section completely detaches from the arc-shaped abutment plate as the wire travels, the compression spring releases the first potential energy and multiple support bars release the second potential energy, which together drive the slider to move the compression rod in the opposite direction quickly. This causes the marking head at the bottom of the compression rod to pop out and abut against the surface of the wire in the defect area that just passed the detection ring, applying a visible mark to the defect area. After the marking is completed, the support bars pull the support ring back to its original position, the system returns to the inspection state, and the winding continues.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. This invention constructs a three-section swing arm guide structure on the winding path, which includes entry positioning, intermediate pre-tensioning, and exit width limiting and winding. It utilizes the winding block to establish a path reference, the pressing block to establish a constant frictional pre-tensioning force, and the swing arm guide ring hole to constrain the radial runout amplitude. The three functions work in a progressive and coordinated manner, simultaneously solving the problems of slack rebound and interlayer skipping during the winding of low-rigidity paper rope from three dimensions: path constraint, tension stability, and arrangement accuracy.

[0017] 2. This invention constructs an enclosed detection structure by evenly distributing multiple sets of arc-shaped abutment plates around the circumference of the detection ring. It utilizes the essential physical property difference of approximately one order of magnitude in radial hardness between the moisture-absorbing and expanding section of the paper rope (soft, radially compressible) and the knotted defect section (hard, radially incompressible). The equivalent positioning stiffness of the arc-shaped abutment plate system is designed between the hardness values ​​of the two, enabling automatic identification that the soft expansion section is compressed without triggering the action, while the hard defect section pushes open the arc-shaped abutment plate and triggers the action. The entire process is purely mechanical and requires no machine downtime, solving the problem that existing go-no-go rings cannot distinguish between two types of over-diameter properties based solely on size thresholds.

[0018] 3. This invention converts the work done by the arc-shaped abutment plate being pushed open by the defect segment into elastic potential energy by setting a compression spring and a support bar as dual elastic energy storage elements in the feedback component. At the moment when the tail edge of the defect segment detaches from the arc-shaped abutment plate, the potential energy is automatically released to drive the marking head to eject and impact the wire surface to complete the pigment transfer. This achieves time-sequential self-coupling of detection and marking actions, with no sensor delay, no controller response lag, and the marking position is naturally synchronized with the defect segment, solving the problem of accurately marking the defect position when the wire is continuously moving.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1 Existing wire winding devices typically employ a simple method of rotating a motor-driven drum to engage fixed wire holes when winding paper ropes or paper-based binding wires.

[0023] This method has the following problems: the paper rope itself is made of plant fiber twisting, and its tensile strength and stiffness are far lower than those of metal wire or chemical fiber thread. If there is a lack of effective tension pre-tensioning and path constraint during the winding process, the thread is very prone to loosening and rebounding, interlayer skipping, local stacking and other poor arrangement phenomena, resulting in an uneven appearance of the finished roll and frequent entanglement and jamming during subsequent unwinding.

[0024] Especially in the suspended section between the wire feeder and the winding drum, if there is no radial amplitude limiting mechanism, the wire will bounce up and down due to equipment vibration or tension fluctuations, resulting in uneven wire laying surface, which seriously affects the winding quality and subsequent automated unwinding.

[0025] like Figures 1 to 3 In this embodiment, the winding table 1 is a box-type metal frame structure with leveling feet at the bottom and a horizontal work surface on the top. A drive block 11 is installed inside the winding table 1. The drive block 11 is a geared motor with its output shaft extending vertically upward through the top surface of the winding table 1.

[0026] The output end of the drive block 11 is connected to the drive disk 12 via a key. The drive disk 12 is a flange-type disc with a positioning boss at the center of its upper surface. The winding drum 13 is a hollow cylindrical body, and its bottom center hole is fitted onto the positioning boss of the drive disk 12 and axially pressed and fixed by a lock nut.

[0027] The swing arm assembly 2 is installed on one side of the winding table 1, including a winding block 21 fixed to the side wall of the winding table, a pressing block 22 installed on the winding block 21, and a swing arm 23 installed at one end of the winding block 21. The wire passes through the guide hole of the winding block 21 in sequence, is pre-tightened by the pressing block 22, passes around the wire ring hole at the end of the swing arm 23, and is then connected to the winding drum 13.

[0028] Working principle of drive assembly and swing arm assembly: After the drive block 11 is started, the output shaft of the drive block 11 rotates, which drives the drive disk 12 to rotate synchronously. The drive disk 12 then drives the winding drum 13 to rotate around its own axis at a set speed, so as to continuously wind and bind the wire.

[0029] After the wire is led out from the wire feeder, it first passes through the guide hole of the winding block 21. The winding block 21 provides the first positioning reference point for the wire to enter the winding area. After the wire passes through the winding block 21, it passes through the pressing block 22. The pressing block 22 is a spring pre-tightening pressure plate structure. Its pressure plate end presses against the surface of the wire with a constant normal force, providing controllable frictional pre-tightening force for the wire, ensuring that the wire always maintains appropriate tension in the section between the winding block and the winding drum without loosening or shaking. After passing through the pressing block 22, the wire enters the conductor ring hole at the end of the swing arm 23. Under the action of the reciprocating drive mechanism, the swing arm 23 swings periodically back and forth along the axis of the winding drum, driving the wire to be evenly arranged layer by layer on the wall of the winding drum. At the same time, the hole wall of the conductor ring hole plays a limiting and constraining role on the vertical jump of the wire.

[0030] It should be emphasized that the core improvement of this embodiment lies in the construction of a three-section swing arm guide structure—entry positioning, intermediate pre-tensioning, and exit limiting thread arrangement—to address the low strength and low stiffness of paper rope. The winding block 21 establishes a path reference to eliminate directional deviation of the incoming thread; the pressing block 22 establishes a constant frictional pre-tensioning force without damaging the fiber surface to eliminate relaxation and rebound caused by tension fluctuations; and the guide ring hole of the swing arm 23, while achieving axial thread arrangement, limits the radial runout of the thread within the gap between the hole walls. These three components are arranged in series along the thread's travel direction, with progressive functions and coordinated cooperation, simultaneously ensuring the winding quality of the paper rope from three dimensions: path constraint, tension stability, and arrangement accuracy.

[0031] It should be noted that the preload of the pressing block 22 can be set by adjusting the compression of its internal spring. For paper ropes with a nominal diameter of 1.5 to 3.0 mm, the normal preload of the pressing block should preferably be set in the range of 0.5 to 2.0 N. This force value can effectively eliminate slack in the rope without causing the surface fibers of the paper rope to fray or break due to excessive friction. If a different diameter or material of rope is used, the operator can change the spring compression by rotating the adjusting screw on the top of the pressing block to match the new preload requirement.

[0032] It should be noted that one end of the swing arm 23 is hinged to a pin on the winding block 21, and the other end extends outward. The inner diameter of the wire ring hole at the extended end is designed to be 1.5 to 2.0 times the nominal diameter of the wire. The design motivation for this hole diameter ratio is that if the hole diameter is too large, the amplitude limiting function will be lost, and the wire's jump amplitude will be unrestrained; if the hole diameter is too small, the wire will frequently scrape against the hole wall, causing fiber damage.

[0033] When set to 1.5 to 2.0 times the nominal diameter, an annular gap of about 0.5 to 1.0 mm is left between the wire and the hole wall during normal winding. This gap allows the wire to move freely within the normal tension fluctuation range without generating additional friction, and the hole wall limits the amplitude of the jump to a safe range when abnormal jump occurs.

[0034] like Figures 1 to 3 In this embodiment, the inner wall of the guide hole of the winding block 21 is mirror-polished to a surface roughness level of Ra 0.4μm or lower. The motivation for this design is to reduce the coefficient of friction between the paper rope and the wall of the hole when the paper rope passes through, and to prevent the fibers on the surface of the paper rope from being scratched and fuzzed by the rough wall during continuous high-speed passage. The guide hole inlet end of the winding block 21 is provided with a flared inlet section with a flare angle of about 15°, so that even if the wire enters with a small angle of deflection, it can be smoothly guided into the center of the hole without getting stuck at the edge of the hole inlet and causing stress concentration.

[0035] The upper surface positioning boss of the drive disc 12 and the bottom center hole of the winding drum 13 are fitted with an H7 / h6 clearance. The mating surfaces are nitrided to improve wear resistance and ensure that the positioning accuracy does not decrease under long-term repeated loading and unloading of the winding drum. The winding drum 13 has an axial wire clamping groove on its wall, with a groove depth of about 1.0 mm and a width of about 3.0 mm, which is used to clamp the starting end of the wire. After the wire end is inserted into the clamping groove, it is clamped and fixed by the elastic edge of the groove opening, without the need for additional knotting or gluing. This facilitates operation and avoids the impact of knotting protrusions on the flatness of the first layer of wiring.

[0036] Example 2 It is understandable that in Embodiment 1, the swing arm assembly 2 guides the wire in an orderly manner through the winding block 21, the pressing block 22 and the swing arm 23 to the winding drum 13 to complete the winding.

[0037] However, in actual production, local over-diameter phenomena often occur during the conveying and unwinding process of paper rope, that is, the radial dimension of a certain section of the wire suddenly increases. The causes of this over-diameter phenomenon are divided into two categories: one is hygroscopic expansion, where local sections of the paper rope absorb moisture due to contact with moisture, such as from warehouse dampness or the conveying path passing through a humidified area. The swelling between fibers leads to an increase in radial dimension of about 15% to 30%. For example, the diameter of the damp section of a paper rope with a nominal diameter of 2.0 mm can reach 2.3 to 2.6 mm.

[0038] The second type is structural defects, namely, the knotted joint section where two short paper ropes are knotted at the ends to form a continuous long line, and the overlapping and winding section where the paper strips are not trimmed flat at the beginning of the overlap, resulting in local double-layer superposition. The outer diameter of such defective sections can be 1.5 to 2.0 times the normal value.

[0039] The problem is that the two types of over-diameter wires are very similar in appearance, both showing a sudden increase in radial diameter in a certain section of the wire. However, the existing go-no-go ring detection method can only determine whether the wire is over-diameter or not, and cannot distinguish whether the over-diameter is a harmless reversible moisture absorption expansion or a harmful permanent structural defect.

[0040] If all over-diameter sections are indiscriminately treated as defects and cut off, a large amount of normal wire will be wasted because the damp sections will return to their original diameter and mechanical properties will be undamaged after natural drying. If they are ignored, the actual knotted sections will be rolled into the finished roll, causing jamming or breakage at the perforation, winding, and heat sealing stations of the subsequent automatic packaging machine. Therefore, a detection method that can distinguish between the two types of over-diameter properties in real time during the winding process is needed.

[0041] like Figures 4 to 6 To solve the above problems, a detection component 3 is installed on the end face of the winding block 21 facing the direction of the incoming wire. The detection component 3 includes a detection ring 31, which is an annular shell with a central through hole for the wire to pass through.

[0042] Multiple feedback components 4 are evenly distributed and installed on the outer circumference of the detection ring 31. In this embodiment, feedback components 4 are provided. Each set of feedback components 4 includes a feedback cylinder 41. The feedback cylinder 41 is a cylindrical shell, and the cylinder axis is fixed to the outer wall of the detection ring 31 with the radial attitude cylinder axis pointing towards the center of the detection ring.

[0043] A slider 46 is slidably connected inside the feedback cylinder 41. A pressing rod 42 is installed at the bottom of the slider 46. The pressing rod 42 passes through the limiting block 45 installed on the inner wall of the feedback cylinder and extends to the inner end of the limiting block 45. An arc-shaped abutment plate 43 is installed at the end of the pressing rod 42 facing the center of the detection ring.

[0044] The curvature of the inner arc surface of the arc-shaped abutment plate 43 is approximately matched with the curvature of the nominal outer diameter of the wire. The diameter of the inscribed circle formed by the arc-shaped abutment plates 43 is slightly larger than or equal to the nominal diameter of the wire, so that the arc-shaped abutment plate 43 forms a slight contact or micro-gap with the surface of the wire passing through the central through hole of the detection ring 31 in a natural state.

[0045] The wire continuously passes through the central through hole of the detection ring 31 at the winding speed. The arc-shaped abutment plate 43 is always in radial contact with the surface of the wire. When a section of the wire exceeds the diameter and reaches the position of the detection ring, the bulging surface of the section interacts with the inner arc surface of the arc-shaped abutment plate 43 in a radial force. If the section exceeds the diameter due to moisture absorption and expansion, its fibers become soft after fully absorbing water and have high radial compressibility. The radial pressure applied to it by the arc-shaped abutment plate 43 is sufficient to cause local compression indentation on the surface of the expanded section. That is, the expanded section is pressed back instead of pushing the arc-shaped abutment plate out. The arc-shaped abutment plate basically does not move radially outward, and the extrusion rod 42 does not move. It is determined to be a harmless section.

[0046] If the over-diameter section has a knot or overlap defect, the overlapping of its double-layer dry fiber structure results in extremely high radial hardness. The pressure applied by the arc-shaped abutment plate 43 cannot produce a considerable compression indentation on its surface. The hard defect section acts like a rigid cam, forcibly pushing the arc-shaped abutment plate 43 radially outward, causing the extrusion rod 42 to slide outward toward the feedback cylinder 41. The system determines it to be a harmful defect section.

[0047] It should be emphasized that the core improvement of this embodiment lies in the fact that the two types of paper ropes are distinguished by the essential difference in radial hardness rather than the difference in appearance size. The moisture-absorbing section is soft due to fiber swelling and has a radial compressive modulus of about 0.2 to 0.5 MPa, while the knotted section is hard due to structural overlap and has an equivalent radial compressive modulus of about 5 to 15 MPa, which is about an order of magnitude different from the other two.

[0048] By designing the equivalent positioning stiffness of the enclosure detection structure composed of multiple arc-shaped abutment plates to correspond to a radial compressive stress level of approximately 1 to 2 MPa, and ensuring that this stiffness threshold falls precisely between the two types of overdiameter hardness values, it is possible to achieve the following: the soft expansion section is compressed by the arc-shaped abutment plates without triggering the mechanism to move, while the hard defect section pushes open the arc-shaped abutment plates and triggers the mechanism to move. The entire process is purely mechanical, without electrical sensing, and requires no machine stoppage, and the identification is completed in real time during the winding process.

[0049] It should be noted that the sliding friction between the extrusion rod 42 and the through hole of the limiting block 45, the bending stiffness of the arc-shaped abutment plate 43 itself, and the pre-tightening force component of the support strip 49 on the extrusion rod 42 in the initial position can be adjusted in actual engineering design by selecting the fit clearance and surface roughness between the through hole of the limiting block 45 and the extrusion rod 42, thereby fine-tuning the equivalent positioning stiffness threshold.

[0050] For example, for a paper rope with a nominal diameter of 2.0 mm and a tensile strength of about 20 N, the radial outward thrust required for the extrusion rod to begin sliding due to the triggering force of each set of arc-shaped abutment plates is designed to be about 1.5 to 3.0 N. This force is less than the radial force of the knotted section on the arc-shaped abutment plate of about 5 to 10 N, but greater than the radial force of the damp section on the arc-shaped abutment plate of about 0.3 to 0.8 N, thus ensuring sufficient discrimination margin.

[0051] It should be noted that the design of the evenly distributed feedback components 4 is not an arbitrary choice. The arc-shaped abutment plates 43 surround the wire from multiple directions. Regardless of whether the cross-sectional shape of the wire's over-diameter section is completely regular, the knotted section is usually irregularly raised, which can ensure that at least two sets of arc-shaped abutment plates are in effective contact with the raised surface, thus avoiding misjudgment caused by wire eccentricity when contacting a single point.

[0052] like Figures 4 to 6 In this embodiment, the design motivation for installing the detection ring 31 on the end face of the winding block 21 in the direction of the incoming wire is that the wire enters the guide through hole of the winding block 21 and the pre-tightening area of ​​the pressing block 22 only after passing through the detection ring 31. This means that the axial tension on the wire in the detection area is only the natural drooping tension on the incoming wire side, which is very small, rather than the winding tension after being pre-tightened by the pressing block, which is larger.

[0053] Lower axial tension is beneficial to the radial force detection sensitivity of the arc-shaped contact plate 43. If the wire is under high tension in the detection area, its cross-section will shrink radially due to the Poisson effect, reducing the actual apparent size of the over-diameter section and lowering the detection sensitivity.

[0054] Placing the detection ring in the low-tension area before the pressing block maximizes the preservation of the true radial dimension characteristics of the over-diameter section, improving identification accuracy. Furthermore, the inner arc surface of the curved abutment plate 43 is mirror-polished to below Ra0.2μm to reduce frictional resistance as the wire slides across its surface, ensuring unimpeded wire movement. Paper rope fibers are prone to fraying and snagging on rough surfaces; polishing effectively prevents this problem.

[0055] Example 3 Understandably, in Embodiment 2, after the detection component 3 identifies the hard defect segment through the arc-shaped abutment plate 43, the arc-shaped abutment plate 43 is radially pushed open and the extrusion rod 42 slides outward, and the system has learned that there is a defect here.

[0056] However, recognizing the existence of a defect is only the first step. More importantly, a visible mark needs to be left on the surface of the wire at the location of the defective section so that the operator can visually locate and cut off the defective section after winding.

[0057] The problem is that the wire must maintain a constant speed during the winding process. The typical winding speed is 0.5 to 2.0 m / s. It is impossible to stop winding in order to mark a defective section. Frequent start and stop not only seriously reduces production efficiency, but also poses a risk of breakage for low-strength wires such as paper rope due to the tension impact generated by each start and stop.

[0058] Therefore, the marking action must be completed instantly while the wire is continuously moving, and the marking position must accurately correspond to the defect area rather than being offset to the normal section.

[0059] Traditional external inkjet marking or labeling devices rely on electrical sensors to detect signals that trigger the control system to issue inkjet commands. This results in signal transmission delays and actuator response delays. At high linear speeds, the marking position deviation can reach tens of millimeters. For paper rope defects with a knotted section axial length of only about 5 to 15 mm, such deviations are unacceptable.

[0060] A purely mechanical solution is needed that self-couples the detection and marking actions, so that the marking time is naturally synchronized with the location of the defect segment.

[0061] like Figures 7 to 8 To address the aforementioned issues, this embodiment incorporates a precise marking mechanism based on potential energy storage and release within the feedback component 4.

[0062] Specifically: A compression spring 47 is installed on the inner wall of the feedback cylinder 41. One end of the compression spring 47 is connected to the slider 46. When the compression rod 42 is pushed outward by the arc-shaped abutment plate 43, the slider 46 compresses the compression spring 47 to store the first elastic potential energy.

[0063] Meanwhile, the outer side of the compression rod 42 is surrounded by a support ring 48, which is located in the inner cavity of the feedback cylinder 41. Multiple evenly distributed support bars 49 are installed on the top of the limiting block 45. The multiple support bars 49 are connected to the support ring 48. In the initial state, the support bars 49 are in a naturally straightened or slightly pre-tightened state.

[0064] When the extrusion rod 42 moves the support ring 48 outward, the multiple support bars 49 are stretched to generate elastic restoring force and store a second elastic potential energy. A marking head 44 is installed at the bottom end of the extrusion rod 42 facing the central through hole of the detection ring, and the end of the marking head 44 is coated with a transferable pigment layer.

[0065] The working principle of the potential energy storage and release mark: When the hard defect segment enters the detection ring 31 and radially pushes open the arc-shaped abutment plate 43, the extrusion rod 42 slides outward, the extrusion spring 47 is compressed to store the first potential energy, and the support bar 49 is stretched to store the second potential energy.

[0066] During this process, the wire does not stop moving. The hard defect section continues to pass through the detection ring 31 along the axial direction at the winding speed, and its protruding part smoothly slides over the polished inner arc surface of the arc-shaped abutment plate 43.

[0067] During the entire period when the raised area of ​​the hard defect section continuously abuts against the arc-shaped abutment plate 43, the arc-shaped abutment plate remains in an open state, and the two potential energies are continuously maintained.

[0068] When the tail edge of the hard defect segment slides past the contact area of ​​the arc-shaped abutment plate 43 along the direction of wire travel and completely disengages from it, the arc-shaped abutment plate loses its radial outward pushing force. The compression spring 47 releases the first potential energy to push the slider 46 to quickly reset inward, and the multiple support bars 49 release the second potential energy to pull the support ring 48 to quickly reset inward. The combined force of the two potential energies drives the compression rod 42 to eject the marking head 44 towards the central through hole of the detection ring.

[0069] At this moment, the wire section passing through the central through hole of the detection ring is the area that the hard defect section has just passed through. Because the tail edge of the defect section has just left the arc-shaped abutment plate, the body of the defect section is still close to the axial position of the arc-shaped abutment plate. The marking head 44 is ejected and abuts the wire surface in this area. Under the impact pressure, the pigment is transferred to the paper rope surface to form a visible color spot.

[0070] After marking is completed, the continuous tension of the support bar 49 pulls the support ring 48 and the compression rod 42 back to their initial positioning position, the marking head 44 detaches from the wire surface, and the system returns to the inspection state.

[0071] It should be emphasized that the core improvement of this embodiment is that the work done by the arc-shaped contact plate being pushed open during the detection process is converted into elastic potential energy for temporary storage, and then this potential energy is automatically released at the moment the defect segment leaves to drive the marking head to complete the marking.

[0072] This energy storage and release mechanism creates a natural temporal coupling between the detection and marking actions. Energy is stored when the defective segment enters and released to mark it when it leaves. No external sensors, control circuits, or actuator delay compensation are required, and the marking time is automatically synchronized with the defect position.

[0073] The cable travels at a constant speed throughout the entire process without stopping. The marking action is a momentary ejection impact on the order of milliseconds, which has no effect on the cable tension or winding rhythm.

[0074] It should be noted that the axial deviation between the marking position when the marking head 44 is ejected and the actual defective section body is analyzed as follows: the deviation is equal to the axial contact width of the arc-shaped contact plate 43, which is about 2 to 3 mm, plus the distance the wire travels within the ejection time of about 1 to 2 ms, which is about 1 to 2 mm at a wire speed of 1.0 m / s, and the total deviation is about 3 to 5 mm.

[0075] For subsequent manual identification and processing, after seeing the color spot mark, the operator will leave a margin of about 10 to 20 mm before and after the mark for cutting. The marking deviation of 3 to 5 mm is far within the acceptable range and will not affect the complete removal of the defect segment.

[0076] It should be noted that the engineering significance of the parameter relationship that the elastic force of the compression spring 47 on the slider 46 is less than the supporting force of the multiple support bars 49 on the support ring 48 is to ensure reliable reset after marking is completed.

[0077] After the marking head 44 is ejected onto the wire surface, if there is no restoring force to pull it back, the marking head will continue to press against the running wire surface. On the one hand, this will cause unnecessary frictional resistance and affect the winding tension. On the other hand, the continuous contact with the pigment layer will form continuous drag marks rather than discrete color spots on the wire surface, thus losing the positioning function of the position marking.

[0078] The pulling force of the support bar 49 on the support ring 48 always points away from the initial positioning position on the wire surface, and this pulling force is greater than the pushing force of the compression spring 47 on the slider. Therefore, after the marking head completes the pigment transfer within the extremely short time of the ejection impact (approximately 1 to 2 ms), the continuous pulling force of the support bar 49 quickly pulls the marking head back from the wire surface, ensuring that the marking is point-contact rather than dragging, thus achieving accurate discrete color spot marking.

[0079] like Figures 7 to 8 In this embodiment, the transferable pigment layer at the end of the marking head 44 adopts a microcapsule structure design: the pigment microcapsules are thin-walled polymer spheres with a diameter of about 50 to 100 μm, which encapsulate quick-drying ink inside, and a large number of microcapsules are adhered to the elastic pad on the end face of the marking head in a single-layer close-packed manner.

[0080] When the marking head impacts the surface of the thread, the microcapsules in the area in contact with the thread surface rupture under the impact pressure, releasing ink. The ink seeps into the gaps between the fibers on the surface of the paper rope, forming indelible stains. The microcapsules in the areas not in contact with the thread remain intact and do not release ink.

[0081] The design motivation for this microencapsulated pigment layer is that each marking consumes only a small number of microcapsules in the contact area, and the marking head can achieve hundreds to thousands of markings before the pigment layer needs to be replaced, reducing the maintenance frequency.

[0082] In addition, the design of the elastic pad allows the end face of the marking head to adapt to the micro-undulations of the wire surface, ensuring sufficient contact area, full pigment transfer, and clear color spot at the moment of impact.

[0083] The support bar 49 is made of 65Mn spring steel wire with a diameter of about 0.3 to 0.5 mm. It is radially and evenly connected between the top of the limit block 45 and the support ring 48.

[0084] A wire winding method with a swing arm guide structure includes the following steps: S1: Pass the wire through the detection ring 31 and the winding block 21 in sequence, and after being pre-tightened by the pressing block 22, pass it around the swing arm 23 to fix the end of the wire to the winding drum 13; S2: Start the drive block 11, drive block 11 drives drive disk 12 to rotate, drive disk 12 synchronously drives winding drum 13 to rotate, start winding the wire, and swing arm 23 swings back and forth with the winding process to realize wire laying. S3: During the winding process, the wire continuously passes through the detection ring 31, and the arc-shaped abutment plates 43 of multiple feedback components 4 are always in radial contact with the surface of the wire to monitor the radial dimension of the wire in real time. S4: When the wire has an over-diameter section, if the over-diameter section is caused by soft expansion due to moisture absorption, then because of its soft material, the radial pressure applied to it by multiple arc-shaped abutment plates 43 will cause it to be locally compressed and deformed, and the arc-shaped abutment plates 43 will not be able to be opened. The extrusion rod 42 will not be displaced, and it will be determined as a harmless section and will not be marked. If the over-diameter section is caused by a knot or overlap, then because of its hard material, the multiple arc-shaped abutment plates 43 will be opened radially. S5: After the arc-shaped abutment plate 43 is opened, it drives the extrusion rod 42 to move towards the inside of the feedback cylinder 41. The extrusion rod 42 pushes the slider 46 to compress the extrusion spring 47 to store the first potential energy. At the same time, the support ring 48 around the extrusion rod 42 overcomes the holding force of multiple support bars 49 to store the second potential energy. The wire continues to move, causing the hard defect section to slide along the surface of the arc-shaped abutment plate 43. S6: When the hard defect section completely detaches from the arc-shaped abutment plate 43 as the wire travels, the compression spring 47 releases the first potential energy and multiple support bars 49 release the second potential energy, which together drive the slider 46 to move the compression rod 42 in the opposite direction quickly, so that the marking head 44 at the bottom of the compression rod 42 pops out and abuts against the surface of the wire in the defect area that just passed the detection ring 31, and applies a visible mark to the defect area. After the marking is completed, the support bar 49 pulls the support ring 48 back to its original position, the system returns to the inspection state, and the winding continues.
