[0002] In composite material (such as carbon fiber) weaving processes, the spindle is the core yarn storage and feeding device of the weaving machine. It is a small spool or roll used to store and orderly release carbon fiber filaments (or prepreg yarn). During the weaving process, multiple spindles move alternately on tracks according to a predetermined pattern, interweaving the yarns to weave the filaments into preforms with specific structures such as tubular or sheet-like shapes.

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1: Reference Figures 1-12 A spindle for a weaving device, comprising: a horizontal plate 1; Vertical plate 2 is connected to the horizontal plate 1. The horizontal plate 1 and the vertical plate 2 form the spindle seat body. When assembling the spindle seat body, the horizontal plate 1 and the vertical plate 2 can be assembled by welding or bolting. The manufacturer of the device can adjust it according to the actual situation. The optical axis 3 is installed on the vertical plate 2, and the working part of the optical axis 3 is placed in the quadrilateral groove that runs through the middle of the vertical plate 2. A slider 4 is slidably connected to the optical axis 3, and an end of a spring 5 is connected to the slider 4. The other end of the spring 5 is connected to the vertical plate 2. A yarn tube rotating disk 6 is rotatably connected to the slider 4, and the yarn tube rotating disk 6 is in frictional engagement with the brake mechanism 7 on the slider 4. The yarn tube 8, rotatably connected to the slider 4, is concentrically connected to the yarn tube rotating disk 6. The yarn tube 8 is used to store the yarn. When weaving begins, the end of the yarn drawn from the yarn tube 8 of the spindle is placed inside the weaving machine. Under the traction force of the weaving machine, the yarn is continuously pulled out from the yarn tube 8. The traction force is transmitted to the yarn tube rotating disk 6 through the yarn tube 8 and the yarn tube shaft 45. The brake mechanism 7 holds the yarn tube rotating disk 6 tightly, preventing it from rotating initially. The braking reaction force is transmitted to the slider 4 through the yarn tube rotating disk 6 and the yarn tube shaft 45, causing the slider 4 to overcome the elastic force of the spring 5 on the optical axis 3 and slide a certain distance along the optical axis 3. When the slider 4 slides to the set stroke and the traction torque is greater than the braking torque, the yarn tube rotating disk 6 slips relative to the brake mechanism 7, and drives the yarn tube 8 and the yarn tube shaft 45 to rotate on the slider 4 to release the yarn. When releasing the yarn, the yarn passes through the universal wheel mechanism 9 connected to the vertical plate 2. The universal wheel mechanism 9 guides the yarn to prevent it from breaking during pulling. In addition, when the traction force fluctuates during the yarn feeding process, the slider 4 slides slightly near the set stroke to achieve tension compensation; when the yarn is completely fed out or the yarn breaks, causing the tension to disappear, the slider 4 is reset to the initial position under the action of the spring 5, the sensing clip triggers the limit switch, the braiding machine alarms and stops, and after replacing the yarn tube, the yarn can be fed again to enter the next cycle. By adjusting the friction force applied by the brake mechanism 7 to the yarn tube rotating disk 6, the mechanism can accurately adapt to the tension of various yarns to meet the weaving needs of various fibers, preventing yarn fuzzing and breakage during weaving. This not only improves the continuity of weaving but also avoids yarn waste during weaving.

[0020] Example 2: Reference Figures 1-12 The braking mechanism 7 includes: a fastener 71, a brake band 72, a tension spring 73, and a tension spring post 74. The slider 4 cooperates with the fastener 71 to fix the end of the brake band 72. The brake band 72 is in frictional contact with the side wall of the yarn tube rotating disk 6. The other end of the brake band 72 is connected to the end of the tension spring 73. The other end of the tension spring 73 is connected to the slider 4 through the tension spring post 74. The tension spring post 74 has a structure with a threaded part at the bottom. The threaded part is threadedly connected to the threaded hole structure of the slider 4. By turning the tension spring post 74, its extension length on the slider 4 is changed, and the tension of the tension spring 73 is adjusted, thereby changing the magnitude of the frictional force applied by the brake band 72 to the side wall of the yarn tube rotating disk 6. Before the mechanism starts working, in order to meet the tension of different yarns, the relative position of the tension spring column 74 on the slider 4 is adjusted. When it is necessary to increase the friction of the brake mechanism 7, the tension spring column 74 is screwed down to move it downward (i.e., increase the extension length). After the tension spring column 74 is moved downward, the tension spring column 74 is fixed on the slider 4. At this time, the length of the tension spring 73 becomes larger, and the friction applied by the brake band 72 to the side wall of the yarn tube rotating disk 6 increases synchronously. When it is necessary to reduce the friction of the brake mechanism 7, the tension spring column 74 is rotated in the opposite direction to move it upward (i.e., reduce the extension length). After the tension spring column 74 is moved upward, the tension spring column 74 is fixed on the slider 4. At this time, the length of the tension spring 73 becomes shorter, and the friction of the brake band 72 applied to the side wall of the yarn tube rotating disk 6 is reduced simultaneously. In order to improve the adjustment efficiency of the position of the tension spring column 74, the tension spring column 74 has a structure with a threaded part at the bottom, and the threaded part is threadedly connected to the threaded hole structure of the slider 4. Furthermore, the fastener 71 is preferably a bolt. The threaded connection between the bolt and the support plate 75 can reduce the difficulty of connecting the two. The bolt and the through hole at the end of the brake band 72 are engaged to reduce the difficulty of positioning the brake band 72 and improve the accuracy of the installation of the brake band 72, so that it can rub precisely with the yarn tube rotating disk 6 and prevent the component from breaking due to excessive local wear of the brake band 72 caused by improper friction. The nut of the bolt and the support plate 75 are engaged to fix the end of the brake band 72, which further reduces the difficulty of connecting the components and improves the stability of the component connection. The side wall of the support plate 75 is connected to the slider 4 by bolt 2, and the tension spring column 74 is connected to the support plate 75. Braking friction is the mechanical benchmark for yarn tension. Matching these two forces essentially involves adjusting the braking resistance to adapt to the breaking thresholds of different fibers, achieving the core tension control requirement of "no loosening during release and no breakage during pulling." The specific formula for matching friction and tension is as follows: ,in The friction force between the brake band and the rotating disc of the yarn tube. This represents the coefficient of friction between the brake band and the rotating disc of the yarn tube, where N is the normal force exerted by the brake band on the rotating disc of the yarn tube. Indicates the stiffness of a tension spring. This indicates the amount of spring elongation generated by adjusting the tension spring post. The formula describes how the braking mechanism precisely controls yarn tension by adjusting the thread position of the tension spring post. When the tension spring post is screwed on to extend it further, the tension spring is further stretched, generating a greater pulling force. This pulling force is converted into frictional resistance on the yarn tube and the turntable through the brake band. This frictional force must be overcome to drive the yarn tube to rotate, thus achieving adjustable tension control—different yarn materials require different tensions. This mechanism allows for precise adaptation to the weaving needs of various fibers, preventing excessive tension from causing yarn breakage or insufficient tension from causing loose weaving. The braking mechanism 7 further includes a second brake band and a second tension spring. The bottom ends of two second tension springs are connected to the support plate 75. The second tension springs are symmetrically arranged on both sides of the yarn tube rotating disk 6. The top end of the second tension spring is connected to the end of the second brake band. The second brake band is in frictional engagement with the top side wall of the yarn tube rotating disk 6. By adding two second tension springs, the length of the second brake band is reduced, thereby reducing the manufacturing cost of the brake band component.

[0021] Example 3: Reference Figures 1-12 The universal wheel mechanism 9 includes: a support member 92, a guide wheel 93, and a ceramic eye 94. The support member 92 is provided at the top of the upright plate 2 away from the slider 4. The bottom of the support member 92 is rotatably connected to a bearing 91. The bearing 91 is connected to the upright plate 2 by a hollow bolt 95. The guide wheel 93 is rotatably connected to the support member 92. The through hole of the ceramic eye 94 above the guide wheel 93 is inclined towards the side wall of the guide wheel 93. The ceramic eye 94 is rotatably connected to the support member 92 and is fixed to the adjusted angle position by a locking screw. The locking screw is slidably connected to the ceramic eye 94 (the direction of movement of the locking screw when sliding is parallel to the axis of the guide wheel 93). The bottom of the ceramic eye 94 is arranged around the rotation center of the guide wheel 93 on the support member 92. The support member 92 is provided with a circumferential array of multiple screw holes around the rotation center. When adjusting the angle, first rotate the ceramic eye 94 to any angle, and then rotate the locking screw to make it threadedly connected to a screw hole to complete the angle adjustment of the ceramic eye 94. The yarn thread led from the yarn tube 8 passes through the hollow bolt 95, is guided by the guide wheel 93, and then passes through the inclined through hole of the ceramic eye 94. The orientation of this through hole guides the yarn thread to fit against the side wall of the guide wheel 93 at a specific angle, thereby reducing the tangling and friction of the yarn thread during yarn feeding. The ceramic eye 94 is connected to the support member 92 by a universal ball joint or hinge structure. The ceramic eye 94 can adjust its tilt angle relative to the support member 92 within a set range, and the adjusted angle position is fixed by locking screws. When the relative position, direction, or angle between the spindle and the yarn inlet of the braiding machine changes slightly during the weaving process, the support member 92 can be adaptively rotated around its connection point with the top of the upright plate 2, thereby always maintaining the smooth guidance of the yarn thread by the ceramic eye 94 and the guide wheel 93, keeping the yarn thread output direction consistent with the tension direction, and avoiding hard bending.

[0022] The universal wheel mechanism 9 optimizes the yarn exit path, further solving the problems of fuzzing and breakage of special yarns, and achieving continuous weaving and efficient operation; During yarn feeding, the process transforms the yarn guide from a "hard bend" to a "smooth roll," allowing the yarn to conform to the guide wheel with minimal bending stress and no tangential scraping. This avoids the brittle breakage caused by sharp angles, which is a major concern for carbon fibers, and eliminates fuzzing from repeated folding. Essentially, it's a "machining protection threshold for the yarn path" tailored for brittle fibers. Therefore, determining the optimal angle between the ceramic eye 94 through hole and the guide wheel axis 93 is crucial. The following formula is used to calculate this angle. ,in This indicates the optimal tilt angle of the ceramic eye through-hole relative to the guide wheel axis. Indicates the radius of the guide wheel. This indicates the guiding distance from the ceramic eye to the contact point of the guide wheel. For example, if the radius of the guide wheel 93 is R=15mm and the distance from the ceramic eye 94 to the guide wheel side wall is L=40mm, we can substitute θ≈20°. The actual adjustment range is set to 15°-35°, preferably 25°. At this time, the angle between the yarn exit direction and the traction force is ≤8° and the bending radius is ≥30mm, which meets the allowable bending requirements of carbon fiber.

[0023] Example 4: Reference Figures 1-12 The top of the upright plate 2 is threadedly connected to the bottom of the hollow bolt 3 95. The shoulder of the hollow bolt 3 95 is located above the top of the upright plate 2 and contacts the bottom of the bearing 91. The bearing 91 is inserted into the top of the hollow bolt 3 95. The top of the hollow bolt 3 95 is threadedly connected to a nut 96. The nut 96 and the shoulder cooperate to clamp the bearing 91, which reduces the difficulty of connecting the components and improves the disassembly efficiency between the components.

[0024] Example 5: Reference Figures 1-12The upright plate 2 is provided with two optical axes 3. The two end sidewalls of the optical axes 3 respectively contact and cooperate with a groove 21. The groove 21 is opened on the upright plate 2. After the end sidewall of the optical axis 3 contacts and cooperates with the groove 21, the optical axis 3 can be initially positioned. When the other sidewall of the optical axis 3 contacts and cooperates with the end face of the pressure plate 22, the positioning of the optical axis 3 in the mechanism is completed. Alternatively, based on the actual situation, it is preferable to open a second groove on the end face of the pressure plate 22, so that the second groove contacts the other sidewall of the optical axis 3. At this time, the upright plate 2 and the pressure plate 22 cooperate to clamp the optical axis 3. To improve the stability of the installation, the pressure plate 22 and the upright plate 2 need to be connected by bolts.

[0025] Example 6: Reference Figures 1-12 To improve the smoothness of sliding between the slider 4 and the optical axis 3, two through holes 41 can be opened longitudinally on the slider 4. A linear bearing 42 is inserted into the through hole 41, and the optical axis 3 slides in the linear bearing 42.

[0026] Example 7: Reference Figures 1-12 Since a quadrilateral groove is provided through the middle of the upright plate, in order to ensure that the moving slider 4 will not collide with the top wall of the upright plate 2, a limit rod 43 is threadedly connected to the bottom end of the slider 4. The top end of the limit rod 43 is set towards the top wall of the upright plate 2. When the slider 4 moves into position, the top end of the limit rod 43 contacts the top wall of the upright plate 2 to prevent the slider 4 from directly colliding with the upright plate 2.

[0027] Example 8: Reference Figures 1-12 To improve the smoothness of the rotation of the yarn tube rotating disk 6 and the yarn tube 8, a deep groove ball bearing 44 is installed in the transverse through hole in the middle of the slider 4. A yarn tube shaft 45 is connected inside the deep groove ball bearing 44. The yarn tube rotating disk 6 and the yarn tube 8 are coaxially connected to the yarn tube shaft 45 in sequence. The yarn tube rotating disk 6 is located between the yarn tube 8 and the slider 4 to prevent the yarn from contacting other parts of the device during yarn feeding.

[0028] Example 9: Reference Figures 1-12It also includes: a sensing clip; the slider 4 is connected to a sensing clip, which moves with the slider 4. The sensing clip is set towards the limit switch on the braiding machine. When yarn tension exists, the braiding machine pulls the yarn slider 4 to move the sensing clip away from the limit switch. When the yarn tension disappears, the slider 4 is reset under the reset force of the spring 5, which drives the sensing clip to move and triggers the limit switch. The braiding machine alarms and stops. When performing braiding work, the slider 4 is pulled by the yarn and overcomes the pressure of the spring 5, moving away from the horizontal plate 1. When the yarn is used up or breaks during the braiding process, the slider 4 will be reset under the reset force of the spring 5, that is, the slider 4 will move towards the horizontal plate 1. As the slider 4 moves, the sensing clip connected to it moves synchronously. When the sensing clip contacts the limit switch, the braiding machine alarms and stops. This realizes the alarm steps for spinning faults and prompts the equipment operator to deal with them in time. The limit switch in the technical solution can be installed on the braiding machine. Its function is to efficiently arrange the limit switches based on the remaining space in the device for braiding machines of different sizes.

[0029] Example 10: Reference Figures 1-12 A pump 46 is connected to the slider 4. The input shaft of the pump 46 is connected to the end of the yarn tube shaft 45. A bevel gear 47 is connected to the input shaft. The bevel gear 47 meshes with a second bevel gear 48. The second bevel gear 48 is connected to a second rotating shaft 49. The second rotating shaft 49 is rotatably connected to a filter tube 491. A cam 492 is connected to the end of the second rotating shaft 49 inside the filter tube 491. The cam 492 frictionally engages with the filter screen 493 at the end of the filter tube 491. The other end of the filter tube 491 is connected through the end of a conduit 494. One end is connected to the end of the air pump 46, and the other end of the air pump 46 is connected to the end of the second conduit 495. The inside of the slider 4 is provided with an installation cavity 496. Two guide tubes 497 are connected inside the installation cavity 496. The two openings of the guide tubes 497 are opened on the side wall of the slider 4. The other end of the second conduit 495 is connected to the inner wall of the guide tube 497. The other end of the second conduit 495 is set towards an exhaust hole 498. Multiple exhaust holes 498 are opened on the side wall of the optical axis 3. The inside of the optical axis 3 is provided with a cavity, and the cavity is connected to the exhaust hole 498. The optical axis 3 has a strip-shaped groove or annular air groove extending along the axial direction of the optical axis 3 on its side wall. The strip-shaped groove or annular air groove is connected to the cavity inside the optical axis 3. The air outlet end of the guide tube 497 on the slider 4 corresponds to the position of the strip-shaped groove or annular air groove on the side wall of the optical axis 3 through the internal channel of the slider 4. When the slider 4 slides along the optical axis 3 to any working position, the air outlet end of the guide tube 497 remains connected to the cavity inside the optical axis 3 through the strip-shaped groove or annular air groove. When the yarn is unloaded, the yarn itself will produce lint and dust. The spring 5 is located above the slider 4, in the same direction as the yarn. The input shaft of the air pump 46 is connected to the yarn tube shaft 45. Therefore, when the yarn tube shaft 45 rotates, the air pump 46 can start working. After the air pressure in the conduit 495 connected to the air pump 46 increases, the air in the guide tube 497 can enter the cavity inside the optical shaft 3 through an exhaust hole 498, and then be discharged through other exhaust holes 498 located outside the slider 4. During the air discharge process, the exhaust holes 498 facing the spring 5 can blow away the dust or lint attached to it, preventing the spring 5 from being unable to deform smoothly after the accumulation of debris. This further avoids the phenomenon of tension adjustment failure of the mechanism and further avoids the phenomenon of yarn breakage. While exhausting air, the bevel gear 47 is connected to the input shaft through the air pump 46. Therefore, the rotation of the bevel gear 47 can drive the second bevel gear 48 to rotate synchronously, which in turn drives the second shaft 49 to rotate. The second shaft 49 drives the cam 492 to rotate in the filter tube 491. When the air pump 46 is working, the negative pressure in the duct 494 ensures that the air in the filter tube 491 is input into the air pump 46. The filter screen 493 can filter out dust and lint from the environment and prevent debris from accumulating inside the air pump 46 or the optical shaft 3. Furthermore, the rotating cam 492 can vibrate the filter screen 493 to clean the dust and lint adsorbed on it, thus avoiding the need for manual cleaning.

[0030] Example 11: Reference Figures 1-12The yarn tube shaft 45 has an opening 500 at its end away from the air pump 46. Multiple annular cavities 501 are provided inside the yarn tube shaft 45, concentrically connected to the opening 500. Two sliding grooves 502 are formed on the inner wall of each annular cavity 501. The inner wall of each sliding groove 502 is connected to the end of a spring 503. The other end of the spring 503 is connected to a mounting plate 504. The mounting plate 504 is connected to a lifting lock block 505, which slides within the annular cavity 501. The top of the lifting lock block 505 is inserted into a slot 506 in the yarn tube 8. The slot 506 is located within a mounting through hole in the yarn tube 8. An inclined surface 507 is provided on the top of the lifting lock block 505 away from the slider. A sliding connection is provided within the opening 500. The unlocking rod 508 is connected to multiple unlocking discs 509, which correspond one-to-one with the annular cavity 501. The unlocking disc 509 is longitudinally connected to the ends of two unlocking rods 510, and the other end of each unlocking rod 510 is set towards a transverse groove 511. The transverse groove 511 is set on the end face of the lifting lock block 505 away from the slide groove 502. The yarn tube shaft 45 is provided with an annular cavity 512, which is connected to the opening 500. The side wall of the unlocking rod 508 placed in the annular cavity 512 is connected to the mounting plate 513. The mounting plate 513 is connected to the inner wall of the annular cavity 512 through a spring 514. The unlocking rod 508 slides in cooperation with the opening 500.

[0031] After the yarn in the mechanism is used up, the yarn tube 8 needs to be disassembled and new yarn wound around it. At this time, the unlocking rod 508 can be pressed towards the slider 4. After the spring 514 is compressed, the unlocking rod 508 is rotated. The unlocking disc 509 moves towards the lifting lock block 505 first, and the unlocking rod 510 moves synchronously and is inserted into the transverse groove 511. The transverse groove 511 is a spiral groove or inclined groove opened along the circumference of the lifting lock block 505. The bottom of the groove has an inclined surface or a spiral angle along the axial direction of the lifting lock block 505. The rotating unlocking disc 509 drives the second unlocking rod 510 to move along the transverse groove 511. The end of the second unlocking rod 510 slides in contact with the inclined or spiral surface of the transverse groove 511. Under the drive of circumferential rotation, an axial force is generated, which drives the lifting locking block 505 to move downward. After the spring 503 is compressed, the top of the locking block 505 disengages from the slot 506. At this time, the yarn tube 8 can be directly removed from the yarn tube shaft 45. After releasing the unlocking rod 508, the spring 503 and the second spring 514 return to their original positions. Then, the yarn tube 8 after the yarn has been replaced can be directly inserted. When connected to the yarn tube shaft 45, the inclined surface 507 contacts and engages with the side wall of the mounting through hole in the middle of the yarn tube 8, and the spring 503 is compressed. After the locking block 505 is inserted into its corresponding slot 506, the yarn tube 8 is fixed on the yarn tube shaft 45. Since the spring 503 is installed in the mechanism and the yarn tube 8 and the yarn tube shaft 45 are in a rotating state during operation, the locking block 505 can be stably inserted into the slot 506. Moreover, the end face of the locking block 505 facing the slider 4 is a vertical end face, so there will be no axial movement of the yarn tube 8.
