Description

Technical Field

[0001] This utility model relates to the field of braiding machine technology, specifically to a yarn diameter detection device for braiding machines. Background Technology

[0002] As described in the published patent CN222434762U, the safety rope is woven from synthetic fibers and is an auxiliary rope used to connect to the safety belt. Its function is to provide double protection and ensure safety.

[0003] When making safety ropes, a braiding machine is needed to braid several threads. However, existing braiding machines require manual stopping during use and cannot be automatically stopped according to the braiding progress, resulting in a low level of intelligence.

[0004] In summary, after the applicant's rope braiding machine completes the rope braiding, it will coil the rope into a spool for easy delivery. If there are defects in the rope, since the entire spool of rope is in a coiled state, customers who use the rope to process products (the applicant does basic processing, and the applicant's customer base will also perform secondary processing on the rope) will not easily notice them during use, which will ultimately affect the end-user's experience and may even lead to safety accidents (such as for products used for safety protection).

[0005] In existing technologies, some rope and ribbon braiding machines cannot monitor the braiding quality in real time, and cannot automatically stop when there are product defects, which affects the product yield. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-9 A yarn diameter detection device for a braiding machine includes a frame 100, on which a detection bracket 101 is fixedly mounted, and on which a detection module 102 is fixedly mounted;

[0034] The detection module 102 includes a first guide component 103, a second guide component 104 and a detection component 105 arranged sequentially from bottom to top;

[0035] The first guide assembly 103 includes a first guide disk 106, on which a first guide hole 107 is formed through vertically;

[0036] The second guide assembly 104 includes a mounting base plate 108 fixedly connected to the detection bracket 101. A second guide disk 109 is mounted on the mounting base plate 108. A second guide hole 110 that aligns with the first guide hole 107 is opened on the second guide disk 109. A support rod 111 is fixedly mounted on the upper end surface of the mounting base plate 108. A connecting rod 112 that is fixedly connected to the first guide disk 106 is fixedly mounted on the lower end surface of the mounting base plate 108.

[0037] The detection component 105 includes a mounting ring 113, which is fixedly connected to the support rod 111. The mounting ring 113 is provided with a plurality of probe components 114 for wire diameter detection evenly along the circumferential direction.

[0038] The first guide hole 107 (lower plate) and the second guide hole 110 (upper plate) form a vertical guide structure through a rigid connecting rod 112, which forcibly corrects the wire path. Compared with single-stage guide, it can eliminate the lateral displacement of the wire caused by the vibration of the braiding machine and provide a low-vibration environment for probe detection.

[0039] The mounting base 108 is rigidly connected to the detection bracket 101, and the support rod 111 and the connecting rod 112 form a support frame to ensure that the detection component 105 has no displacement under high-speed weaving conditions.

[0040] The circumferentially distributed multi-probe components 114 (usually ≥8) surround the wire in a ring array, and simultaneously collect radial data of the entire cross section of the rope. Compared with single-point detection, it can identify hidden defects that are not easily detected by the naked eye, such as local broken wires, bulges, and eccentricity.

[0041] When there are defects in the rope, the probe component 114 detects the fluctuation and, combined with the algorithm analysis, the detection signal is directly connected to the braiding machine control system. After the control system makes a judgment, it triggers an emergency stop to prevent the defective section from being rolled into the finished roll (the operation of the braiding machine is relatively fast, and it is not easy to check the rope defects with the naked eye).

[0042] Ropes wound into coils are difficult to fully inspect during secondary processing (generally, random sampling is performed, which may result in missed inspections). This device enables online full inspection, ensuring that delivered products are defect-free and avoiding losses from batch recalls caused by hidden defects for downstream customers (such as safety belt manufacturers).

[0043] The wire diameter detection device of this invention for a braiding machine effectively solves the problem of existing technologies' difficulty in automatically detecting defects that affect product yield through an integrated guiding structure and real-time monitoring by multiple probes. The alignment of the first guide hole 107 and the second guide hole 110 ensures the stable vertical passage of the wire, while the multiple probe components 114 evenly distributed around the circumference can scan the wire diameter of the entire cross-section of the rope in real time. When defects such as uneven weaving, broken wires, or diameter deviations are detected, the system can immediately trigger an automatic shutdown to prevent defective products from being drawn into the finished product, significantly improving the product yield. Furthermore, it eliminates the risk of terminal safety accidents caused by hidden defects (such as insufficient strength of protective ropes) flowing into the secondary processing stage from the source, while greatly reducing reliance on manual intervention and realizing intelligent closed-loop detection of weaving quality.

[0044] In this embodiment of the present invention, the lower end face of the mounting ring 113 is provided with a plurality of mounting grooves 115 along the circumferential direction. The probe assembly 114 includes a guide plate 116 installed in the mounting groove 115. The front end of the guide plate 116 extends into the mounting ring 113. The rear end of the guide plate 116 is fixedly provided with a limiting protrusion 117. The mounting ring 113 is fixedly provided with a fastener 118 that spans across the mounting groove 115. The fastener 118 is used to limit and fix the guide plate 116 in the mounting groove 115. The fastener 118 is fixedly provided with a probe element 119.

[0045] The front end of the guide plate 116 extends into the mounting ring 113 to form a second-level guide channel, which works in conjunction with the second guide hole 110 to correct the wire deviation angle and eliminate the detection position offset caused by uneven braiding tension.

[0046] The limiting protrusion 117 and the transverse fastener 118 form a slider buckle structure, which allows for quick replacement of the probe 119 and guide plate 116 simply by loosening the bolts. By replacing the first guide plate 106, the second guide plate 109 and the guide plate 116 with different models, different wire diameters of ropes can be adapted, while avoiding the disadvantage of traditional welded probes needing to be replaced as a whole when damaged.

[0047] The circumferential distribution of the mounting slots 115 causes the probe assembly 114 to be radially recessed and nested within the mounting ring 113, reducing the overall thickness and making it suitable for retrofitting models with narrow spaces.

[0048] In this embodiment of the present invention, a limiting groove 120 is provided at the rear end of the fastener 118. A probe connecting rod 121112 is detachably fixed in the limiting groove 120. A probe element 119 is fixed at the lower end of the probe connecting rod 121112. The probe element 119 includes a probe base 122 detachably fixed to the probe connecting rod 121112. An abutment block 123 is fixed on the inner wall of the probe base 122. A probe element 124 is limited and installed in the probe base 122. A spring element 125 is sleeved on the probe element 124. The rear end of the spring element 125 abuts against the abutment block 123, and the front end of the spring element 125 abuts against the probe element 124. A linear displacement sensor 126 is installed at the rear end of the probe base 122 and abuts against the probe element 124.

[0049] The spring component 125 pre-compresses the probe component 124 to form a constant contact force, so that the probe is in real time in contact with the surface of the rope without damaging the thread (traditional rigid probes are easy to scratch synthetic fibers), while compensating for the instantaneous jump of the thread and ensuring the stability of displacement sensing.

[0050] The abutment block 123, spring 125, and linear displacement sensor 126 constitute a multi-stage mechanical-elastic-electronic filter to suppress mechanical vibration interference.

[0051] The probe connecting rod 121112 and the probe base 122 are both detachable. If a single probe component 119 is damaged, only the single part needs to be replaced, which saves costs.

[0052] The linear displacement sensor 126 is rear-mounted to avoid fiber dust contamination.

[0053] In this embodiment of the utility model, an arc-shaped guide groove 127 is provided at the front end of the guide plate 116;

[0054] The arc-shaped structure forms a smooth transition channel, which changes the contact surface of the high-speed passing synthetic fiber rope (such as a safety rope) from point friction to surface sliding, reducing the surface scratch rate. At the same time, the adaptive wrap angle characteristic can accommodate small-amplitude sway of the wire, avoiding wire breakage caused by hard scratching when the braiding tension changes abruptly. Combined with the second guide hole 110, it forms a two-stage guide system of "rigid positioning first and then correction", which controls the lateral offset of the detection position wire within a reasonable range, provides a low-interference detection environment for the probe, and extends the service life of the guide plate 116.

[0055] In this embodiment of the present invention, the mounting base plate 108 is provided with a base plate mounting hole 128, the second guide plate 109 is aligned and engaged with the base plate mounting hole 128, the second guide plate 109 is provided with guide plate mounting holes 129 around its perimeter, and the mounting base plate 108 is fixed with a positioning post 130 that is inserted and engaged with the guide plate mounting hole 129.

[0056] The positioning post 130 mates with the guide plate mounting hole 129 to ensure that the second guide hole 110 is aligned with the first guide hole 107, thus eliminating detection distortion caused by wire threading angle deviation;

[0057] The symmetrically distributed positioning posts 130 at the four corners form a rectangular anti-torsional frame to prevent micro-displacement of the second guide plate 109;

[0058] The second guide plate 109 is easy to replace, extending the overall lifespan of the machine.

[0059] In this embodiment of the present invention, a universal joint 131 is installed at the lower end of the connecting rod 112, the upper end of the universal joint 131 is fixedly connected to the connecting rod 112, and the lower end of the universal joint 131 is fixedly connected to the first guide plate 106.

[0060] Universal joint 131 adaptively deflects in three degrees of freedom, efficiently absorbing the high-frequency vibration transmitted by the spinning wheel of the braiding machine, so that the first guide plate 106 and the second guide plate 109 maintain dynamic alignment. The composite structure of the spherical bearing and cross shaft of universal joint 131 still maintains rotational resistance when subjected to radial load, providing a steady-state detection environment for probe assembly 114.

[0061] The first guide plate 106 automatically adapts to different directions of the rope input path through three-dimensional adaptive deflection, making the rope input more stable.

[0062] In this embodiment of the present invention, a support mounting hole 132 is provided on the mounting base plate 108, and a support rod 111 is inserted into the support mounting hole 132. A plurality of insertion holes 133 are evenly provided on the support rod 111 along the length direction, and bolts for fixing the support rod 111 to the mounting base plate 108 are inserted into the insertion holes 133.

[0063] By using multiple equally spaced insertion holes 133 on the support rod 111 to cooperate with bolts, the height of the mounting ring 113 can be adjusted in multiple stages, allowing the detection module 102 to adapt to the production needs of ropes and straps of different specifications.

[0064] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
