Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-10 This invention provides a technical solution: a hybrid rope braiding machine with a detection mechanism, based on...

[0033] Specifically, the thread placement mechanism 2 includes a placement bracket 201, which has a cross-shaped structure. The lower end of the placement bracket 201 is welded to the upper surface of the frame 1 via a support leg 202. A first bearing 203 is provided in the middle of the upper end of the frame 1. The four corners of one side of the frame 1 are fixedly connected to the mounting block 205 installed on one side of the placement box 204 through grooves. A sealing cover 206 is provided at the upper end of the placement box 204. A limiting rod 207 provided in the middle of the lower end of the sealing cover 206 is engaged with a card seat 208 provided in the middle of the lower end of the placement box 204. A thread outlet hole 209 is provided in the middle of the side of the placement box 204 near the braiding mechanism 4. In use, the thread spool is first placed inside the placement box 204 so that the thread end passes through the thread outlet hole 209 and extends to the outside of the placement box 204. Then, the limiting rod 207 provided in the lower end of the sealing cover 206 passes through the middle of the thread spool and engages with the card seat 208, thereby completing the installation and fixing of the thread spool.

[0034] Specifically, the drive mechanism 3 includes a drive motor 301. The output end of the drive motor 301 is connected to the input shaft 304 located at the lower end of one side of the gearbox 303 via a coupling 302. The output shaft 305 located at the upper end of the other side of the gearbox 303 is engaged with one end of the connecting shaft 306. At the same time, a support limiting mechanism 5 is provided on the outer side of the output shaft 305 and the connecting shaft 306. The support limiting mechanism 5 includes a support cylinder 501. The lower end of the support cylinder 501 is connected to the gearbox 303 housing via a mounting bracket 502. A second bearing 503 is provided on the inner side of the support cylinder 501. The inner side of the second bearing 503 is in contact with the outer side of one end of the connecting shaft 306. The connecting shaft 306 passes through the first bearing 203 installed in the middle of the placement bracket 201 and is detachably connected to the middle of one side of the weaving mechanism 4. In use, the drive motor 301 drives the gearbox 303 to work via the coupling 302. Then, the output shaft 305 on the gearbox 303 drives the connecting shaft 306 to rotate, which facilitates the rotation of the weaving mechanism 4, thereby performing weaving.

[0035] Specifically, the weaving mechanism 4 includes a rotating disk 401, with a wire storage box 402 installed in the center of the rotating disk 401. The wire storage box 402 has symmetrically arranged slots 403 on both sides inside, and a connecting drum 404 is positioned between the two slots 403. The connecting drum 404 is rotatably connected to the wire storage box 402 via a rod 405. A wire outlet 406 is located in the center of the outer side of the wire storage box 402. In use, the wire spool is first fitted onto the connecting drum 404, then both ends of the connecting drum 404 are slidably engaged with the slots 403. Next, the rod 405 passes through the outer side of one end of the wire storage box 402 and the inside of the connecting drum 404, extending to the outer side of the other end of the wire storage box 402, thus installing the wire spool. Then, the wire end passes through the wire outlet 406 and extends to the outer side of the wire storage box 402. The outer side of the rotating disk 401 is closed. Four first wire outlets 407 are symmetrically provided at the center of the wire storage box 402, and an extension base plate 408 is installed on the outer side of one of the four first wire outlets 407. The extension base plate 408 is connected to the rotating disk 401 through a threaded rod 409. A vertical plate 410 is installed on the outer side of the upper end of the extension base plate 408, and a second wire outlet 411 is provided on the vertical plate 410. At the same time, a first detector 412 is installed on the inner side of the middle of the upper end of the extension base plate 408. The first detector 412 is existing technology. When in use, the wire end is passed through the corresponding first wire outlet 407 and second wire outlet 411 on the rotating disk 401, so that the wire is above the first detector 412 when it is being fed. The first detector 412 detects the wire, preventing the wire from being worn and broken due to friction, which would affect the weaving process and improve the practicality of the device.

[0036] according to Figure 1 , Figure 8 and Figure 9As shown, the detection mechanism 6 is installed on the upper end of the frame 1 near the middle position, and the detection mechanism 6 is equipped with an adjustment guide mechanism 7 on the side near the weaving mechanism 4.

[0037] Specifically, the testing mechanism 6 includes a testing box 601. The lower end of one side of the testing box 601 is connected to the upper end of the frame 1 via a fixing rod 602. The testing box 601 has symmetrically arranged first through holes 603 and second through holes 604 on both sides. Lower conveying rollers 605 are respectively arranged on both sides inside the testing box 601. A box cover 606 is installed on the upper end of the testing box 601, and an electric hydraulic cylinder 607 is symmetrically installed about the middle of the lower end of the box cover 606. The output end of the electric hydraulic cylinder 607 is connected to both sides of a horizontal plate 608. Multiple upper extrusion rollers 609 are installed on the lower end of the horizontal plate 608. A second detector 610 is installed on the lower end of the box cover 606 near the second through hole 604. The second detector 610 is for absorbing technology. An extension plate 611 is installed on the side of the testing box 601 near the second through hole 604. The extension plate 611 is equipped with a first guide roller 612. In use, one end of the woven mixed rope is passed through the first through hole 603 and the second through hole 604 on the test box 601, so that the mixed rope inside the test box 601 is located between the lower conveying roller 605 and the upper extrusion roller 609. When the mixed rope needs to be tested, the electric hydraulic cylinder 607 pushes the horizontal plate 608 down, so that the extrusion roller 609 installed at the lower end of the horizontal plate 608 extrudes the mixed rope to test its toughness and tensile strength. Then, under the action of the second detector 610, it is ensured that the mixed rope is not damaged after the toughness and tensile strength test, thus determining that the mixed rope is qualified and improving the practicality of the device during processing. Then, the first guide roller 612 guides and conveys the tested mixed rope.

[0038] Specifically, the adjusting guide mechanism 7 includes a mounting base 701, with a lower roller 702 rotatably connected to the inner center of the mounting base 701. Lifting plates 703 are provided on both sides of the upper end of the mounting base 701. The bottoms of the two lifting plates 703 are connected to the output ends of electric telescopic rods 704 provided on the inner sides of the mounting base 701. An upper roller 705 is rotatably connected between the two lifting plates 703. In use, the woven mixed rope is guided and conveyed by passing it between the lower roller 702 and the upper roller 705. When the woven mixed ropes are of different sizes, the two lifting plates 703 can be raised and lowered by the corresponding electric telescopic rods 704, thereby adjusting the distance between the lower roller 702 and the upper roller 705, thus making it suitable for conveying and guiding mixed ropes of different sizes.

[0039] according to Figure 1 and Figure 10As shown, the winding mechanism 8 is installed on the other side of the upper end of the frame 1, and a bracket 9 is installed on the outer side of the upper end of the winding mechanism 8. At the same time, a second guide roller 10 is installed on the inner side of the upper end of the bracket 9. A third guide roller group 11 is installed on the lower end of the bracket 9 near the detection mechanism 6. The third guide roller group 11 is located above the winding mechanism 8. When in use, the finished mixed rope that has passed the toughness and tensile strength test is passed through the upper end of the second guide roller 10 and then passed down through the middle of the third guide roller group 11 to connect with the winding mechanism 8 for winding.

[0040] Specifically, the winding mechanism 8 includes a fixed base 801, and there are two fixed bases 801. Each of the two fixed bases 801 has a drive baffle 802 symmetrically arranged on one side. A winding drum 803 is arranged between the two drive baffles 802. A support frame 804 is arranged inside the winding drum 803. Fixed insertion holes 805 are symmetrically opened on both sides of the winding drum 803. In use, one end of the mixed rope is first passed through the fixed insertion hole 805 on one side of the winding drum 803. Then, the drive baffle 802 drives the winding drum 803 to rotate, thereby winding up the mixed rope.
