[0063] The material strip that has been cut into multiple sections can be bent into a ring through the cooperation of the clamping and wrapping assembly 43 and the hole-drawing belt auxiliary forming tool 312. The forming tool is pressed against the middle of the material strip, while the ends of the material strip are sucked and clamped by the clamping suction cups 434. When the clamping suction cups 434 rotate synchronously with the wrapping rotating rod 433, the ends of the material strip that are sucked and clamped will also be bent against the sides of the forming tool to form a ring-shaped hole-drawing belt structure. Specifically, in this embodiment, the clamping suction cups 434 are film suction cups. Compared with ordinary suction cups, film suction cups are more stable and reliable when holding the material strip, and will not cause problems such as loosening due to loose grip.

[0064] The welding assembly 44 includes a welding frame 441, a plurality of second lifting mechanical arms 442, and a plurality of ultrasonic welding guns 443. The welding frame 441 is mounted on the sixth slide rail 18 and can slide along the sixth slide rail 18. The welding frame 441 is also provided with a second adjustment slide rail (not shown). The plurality of second lifting mechanical arms 442 are mounted on the second adjustment slide rail of the welding frame 441 and can be adjusted in spacing relative to each other. The plurality of ultrasonic welding guns 443 are respectively mounted on the plurality of second lifting mechanical arms 442 and can be moved up and down by the second lifting mechanical arms 442. The plurality of ultrasonic welding guns 443 are also respectively arranged in upper and lower correspondence with the plurality of clamping and coating assemblies 43.

[0065] The ends of the wound-tie structure, bent into a ring, remain disconnected. The welding assembly 44 then begins operation. The welding frame 441 slides along the sixth rail 18, positioning the ultrasonic welding gun 443 above the wound-tie structure. The second lifting arm 442 then drives the ultrasonic welding gun 443 downward until its lower end contacts the joint at the end of the wound-tie structure. The ultrasonic welding gun 443 then ultrasonically welds the two ends of the wound-tie structure together, forming a complete, ring-shaped wound-tie.

[0066] The first tooling transfer assembly 31 and the film-wrapping gripper assembly 43 each include a scissor-type pitch converter 314, which comprises a plurality of pitch-varying links (not shown) and a plurality of articulated shafts (not shown). The pitch-varying links are arranged in a crosswise arrangement, with the articulated shafts respectively connected to the ends of adjacent pitch-varying links and the intersections of the intersecting pitch-varying links. The articulated shafts at the intersections are also respectively connected to the outsides of the lifting frames 311 or the film-wrapping slides 431 and the bottom of the second mounting frame 421. The scissor-type pitch converter 314 constrains the movement of the lifting frames 311 or the film-wrapping slides 431, thereby ensuring that the spacing between the lifting frames 311 or the film-wrapping slides 431 remains consistent regardless of their sliding motion.

[0067] The film-clamping and wrapping assembly 43 also includes an adjustment rod 437, which is mounted on the film-clamping carriage 431 and meshes with the racks of the respective support seats 432. The adjustment rod 437 can be rotated to adjust the spacing between the opposing support seats 432. The film-clamping and wrapping assembly 433 also includes a second sensor (not shown), which is mounted on the film-clamping carriage 431 and located to one side of the third programmable drive motor 417. The adjustment rod 437 adjusts the relative spacing between the support seats 432, thereby enabling the material-clamping suction cup 434 to absorb and clamp material strips of varying lengths for bend and wrap film forming.

[0068] The second loading assembly 51 includes a second loading frame 511, a third loading frame 512, a plurality of active loading rollers 513, a plurality of loading motors 514, and a plurality of driven rollers 515. The second loading frame 511 is mounted on the front side of the second frame 12, the third loading frame 512 is mounted on the second frame 12 and is located above the sixth slide rail 18, the plurality of active loading rollers 513 and the plurality of loading motors 514 are mounted on the second loading frame 511, and the loading motor 514 is power-connected to the active loading rollers 513. The plurality of driven rollers 515 are mounted on the second loading frame 511 and the third loading frame 512, respectively.

[0069] The first roller conveyor assembly 52 and the second roller conveyor assembly 53 have identical structural designs, each comprising a plurality of drive rollers 521, a conveyor belt 522, and a conveyor motor 523. The plurality of drive rollers 521 are mounted on the second frame 12. The conveyor belt 522 is sleeved around the drive rollers 521 and driven by the drive rollers 521 for rotation. The conveyor motor 523 is mounted on the second frame 12 and is in power connection with the drive rollers 521. The first roller conveyor assembly 52 also includes a lifting roller frame 524 and a flattening roller 525. The lifting roller frame 524 is mounted on the second frame 12 and located at the feed end of the first roller conveyor assembly 52. The flattening roller 525 is mounted on the lifting roller frame 524 and can be adjusted to rise and fall.

[0070] Once the annular hole-drawing strip is formed, the components on the left second frame 12 begin to operate. First, the second loading assembly 51 and the first roller conveyor assembly 52 work together to load the base material and the surface material, respectively, using the active loading roller 513, loading motor 514, conveyor belt 522, and conveyor motor 523. The base material is guided directly onto the conveyor belt 522 of the first roller conveyor assembly 52 via a portion of driven rollers 515. The surface material, on the other hand, bypasses the first roller conveyor assembly 52 via the third loading frame 512 and another portion of driven rollers 515, directly into the high-frequency laminating device 60. Once the base material is flattened onto the conveyor belt 522 of the first roller conveyor assembly 52, the second tooling transfer assembly 32 picks up the forming tooling, along with the hole-drawing strip, from the clamping and coating assembly 43 and transfers it to the base material. The first roller conveyor assembly 52 then conveys the base material, forming tooling, and hole-drawing strip backward.

[0071] The high-frequency pressing device 60 includes a base 61, an upper frame 62, a lower electrode plate 63, an upper electrode plate 64, and a pressing cylinder 65. The base 61 is located between the first roller conveyor assembly 52 and the second roller conveyor assembly 53. The upper frame 62 is mounted above the base 61. The lower electrode plate 63 is mounted on the base 61 and is at the same height as the first roller conveyor assembly 52 and the second roller conveyor assembly 53. The upper electrode plate 64 is mounted on the upper frame 62 and is arranged opposite to the lower electrode plate 63. The pressing cylinder 65 is mounted on the upper frame 62 and can drive the upper electrode plate 64 to move up and down.

[0072] When the base material, the surface material, and the annular hole-drawing tape between them pass through the high-frequency pressing device 60, it begins operating. The pressing cylinder 65 drives the upper plate 64 downward to press the base material, the surface material, and the hole-drawing tape together. Simultaneously, the upper plate 64 and the lower plate 63 emit high-frequency ultrasonic waves. These high-pressure and high-frequency ultrasonic waves tightly bond the three materials together, forming a single, integrated composite hole-drawing tape product.

[0073] The flattening assembly 71 includes a fixed flattening frame 711, a sliding flattening frame 712, a plurality of flattening cylinders 713, a fixed flattening plate 714, and a sliding flattening plate 715. The fixed flattening frame 711 is mounted on the second frame 12 and is located in the middle of the second roller conveyor assembly 53. The sliding flattening frame 712 is mounted on the fourth slide rail 16 and can slide along the fourth slide rail 16. The plurality of flattening cylinders 713 are respectively mounted on the fixed flattening frame 711 and the sliding flattening frame 712. The fixed flattening plate 714 and the sliding flattening plate 715 are both mounted on the lower ends of the flattening cylinders 713 and are respectively arranged above and below the fixed flattening frame 711 and the sliding flattening frame 712.

[0074] The third cutting assembly 72 includes a third mounting frame 721, a sixth programmable drive motor 722, a third cutting frame 723, a third cutting wheel 724, a seventh programmable drive motor 725, a fifth transmission belt (not shown), and a plurality of avoidance rollers 726. The third mounting frame 721 is mounted on the fourth slide rail 16, and the sixth programmable drive motor 722 is mounted on one side of the third mounting frame 721 and can drive the third mounting frame 721 to slide along the fourth slide rail 16. The third mounting frame 721 is also provided with a third cutting slide rail (not shown in the figure), the third cutting frame 723 is mounted on the third cutting slide rail and can slide along the third cutting slide rail, the third cutting wheel 724 is mounted at the bottom of the third cutting frame 723, the seventh programming drive motor 725 is mounted on the other side of the third mounting frame 721, the fifth transmission belt is passed through the third cutting frame 723 and is power-connected to the seventh programming drive motor 725, and several avoidance rollers 726 are all mounted at the bottom of the third mounting frame 721 and are clamped and passed through the conveyor belt 522 of the second roller conveyor assembly 53.

[0075] The second material pulling assembly 73 includes a second material pulling carriage 731, a plurality of second material pulling clamps 732, and a plurality of second clamping cylinders 733. The second material pulling carriage 731 is mounted on the fifth slide rail 17 and can slide along the fifth slide rail 17. The plurality of second material pulling clamps 732 and the plurality of second clamping cylinders 733 are all mounted on the second material pulling carriage 731. The second clamping cylinders 733 are mounted on the second material pulling clamps 732 and can drive the second material pulling clamps 732 to open and close the clamps. The second material pulling clamps 732 are also provided with anti-slip grooves at the upper and lower clamping openings 412.

[0076] After the high-frequency pressing device 60 presses the multi-layer material strips into a composite hole-drawing tape product, the second roller conveyor assembly 53 will further convey the product backward. During the conveying process, the third tooling transfer assembly 33 will first clamp and extract the hole-drawing tape auxiliary forming tooling 312 remaining on the product, and slide the tooling along the seventh slide rail 19 to return the tooling to the first tooling transfer assembly 31 of the first frame 11. Then the flattening assembly 71 will press and flatten the product on the conveyor belt 522 to prevent product wrinkles from affecting the cutting process. Then the third cutting assembly 72 will flexibly cut out hole-drawing tape products of any length according to production requirements, and the cut hole-drawing tape products will be pulled from the second roller conveyor assembly 53 under the pull of the second pulling assembly 73, completing a cycle of automated production of hole-drawing tape products.

[0077] The automated hole-strap forming equipment 100 also includes a detection and replenishment device 80, which includes a detection sensor (not shown) and a replenishment rack (not shown). The detection sensor is installed between the first frame 11 and the second frame 12, aligned with the sixth slide rail 18. The replenishment rack is installed on one side of the second frame 12, aligned with the sixth slide rail 18. Sometimes, during the film clamping process, the strip at the corresponding tooling position may fall, resulting in the annular hole-strap not being properly formed. When the second tooling transfer assembly 32 transfers the forming tooling and the annular hole-strap attached to it, the detection sensor scans the forming tooling and detects whether the annular hole-strap is missing at the corresponding position. If the annular hole-strap is missing, the second tooling transfer assembly 32 transfers the forming tooling directly along the sixth slide rail 18 to the replenishment rack. An operator manually replenishes the annular hole-strap at the corresponding position, and the tooling then re-enters the first roller conveyor assembly 52 for subsequent production and processing.

[0078] Understandably Figures 23 to 24 As shown, in other embodiments, the film clamping and coating assembly 43 further includes a spline transmission and variable pitch structure 438, which includes a plurality of synchronous transmission plates 4381, a spline sliding transmission shaft 4382, a plurality of left-handed ball screws 4383, a plurality of right-handed ball screws 4384, a sixth programmable drive motor 4385, and a fifth transmission belt 4386. The plurality of synchronous transmission plates 4381 are respectively mounted on the bottom of the second mounting frame 421, and each of the plurality of synchronous transmission plates 4381 is provided with a first transmission hole 4381a and a second transmission hole 4381b. The splined sliding transmission shaft 4382 is inserted into the plurality of first transmission holes 4381a. The plurality of left-handed ball screws 4383 and the plurality of right-handed ball screws 4384 are respectively inserted into the plurality of second transmission holes 4381b, and their outer ends are respectively connected to the bottom of the film-wrapping carriage 431 on both sides. The plurality of left-handed ball screws 4383 and the plurality of right-handed ball screws 4384 are all in driving connection with the splined sliding transmission shaft 4382. The sixth programmable drive motor 4385 is installed on one side of one of the film-wrapping carriages 431. The fifth drive belt 4386 is respectively in power connection with the splined sliding transmission shaft 4382 and the sixth programmable drive motor 4385.

[0079] When the spacing between the film clamping assembly 43 and the second cutting assembly 42 needs to be adjusted, simply activate the sixth programmed drive motor 4385. This motor drives the splined sliding transmission shaft 4382 to precisely rotate, which in turn, through the transmission action of the synchronous transmission plate 4381, drives the left-hand ball screw 4383 and the right-hand ball screw 4384 to slide back and forth along the second transmission hole 4381b. The sliding ball screws can further drive the adjacent film clamping assemblies 43 to adjust the spacing between each other. The adoption of the spline transmission variable pitch structure 438, which replaces the scissor-type variable pitch structure, can further improve the variable pitch accuracy of the film clamping assembly 43 and the second cutting assembly 42.

[0080] In summary, the beneficial effects of the automatic forming equipment 100 for hole-drawn tapes of the present invention are as follows: by designing multiple groups of automatic components to cooperate with each other, the formed hole-drawn tapes can be produced quickly and efficiently, and the quality of the formed hole-drawn tapes is more solid and reliable; the corresponding automatic loading structure is designed for different material strips, which can realize fast and accurate loading processing; the design of multiple transfer structures to cyclically transfer and extract the auxiliary forming tooling of the hole-drawn tape can replace the operation of manual pick-up and placement of tooling, further improving the automation and intelligence of production and processing; the design of a slidably adjustable cutting structure can flexibly cut material strips or finished products of different lengths according to needs; the uniquely designed clamping and film-wrapping component 43 can not only realize automatic The invention can not only realize the film forming of the hole draw tape, but also can adjust the spacing between the clamping film components 43 and the spacing between the clamping suction cups 434 according to different production requirements, so as to be suitable for the film forming of hole draw tapes of various specifications; the welding component 44 can firmly weld the material strip into the hole draw tape by ultrasonic welding, and the high-frequency pressing device 60 can also press the hole draw tape with the bottom material and the top material tightly by ultrasonic welding to form an integrated composite layer material; the detection and feeding device 80 can effectively detect the possible missing problem of the hole draw tape after the film is cut and wrapped, so that the operator can promptly perform the feeding operation on the position of the missing hole draw tape; the invention has strong practicality and great promotion significance.
