Description

Technical Field

[0001] The invention relates to the field of plate and strip grinding, and in particular to a wire threading mechanism and a wire threading method. Background Art

[0002] The plate and strip are usually made by hot rolling process. Before actual use, rust, oxide scale, etc. will appear on the surface of the plate and strip, and the surface of the plate and strip needs to be brushed by a brush roller. In order to facilitate disassembly and maintenance, an existing brush roller structure is configured to be equipped with multiple grinding brush discs on the roller shaft. The grinding brush disc includes a brush disc, and the inner side of the brush disc is provided with multiple wire holes evenly distributed along the circumferential direction. A plurality of side-by-side material wires made of resin material are passed through the wire holes. The multiple side-by-side material wires are folded in half along the radial direction away from the brush disc to form two strands of material wires located on both sides of the brush disc. The two strands of material wires are fixed to each other and form a wire bundle for grinding the surface of the plate and strip.

[0003] The manual wire threading method is too inefficient. In order to improve the wire threading efficiency, the applicant previously designed a wire threading mechanism patent with the announcement number CN112353088. It adopts a horizontal layout structure. After the wire transporting mechanism transports the prepared wire forward, the wire cutting mechanism cuts the prepared wire to obtain a predetermined length of cut wire. Then, the wire transporting mechanism continues to transport the wire and pushes the cut wire into the wire hole of the brush disc, so that the two ends of the cut wire are located on both sides of the brush disc respectively; however, this wire threading mechanism has shortcomings.

[0004] The wire transport mechanism and wire cutting mechanism in the entire wire threading mechanism are both arranged horizontally, which requires a large layout space.

[0005] When the wire cutting mechanism cuts and forms the cut wire, the cut wire is actually no longer connected to the prepared wire. When the prepared wire continues to press and force the cut wire into the wire hole, the wire itself is elastic and is easily deformed and spread outwards after being subjected to force, which can easily cause the prepared wire and the cut wire to be misaligned, affecting the wire threading quality and efficiency. Summary of the Invention

[0006] The present invention provides a wire threading mechanism, in which various working mechanisms on the wire threading mechanism are arranged longitudinally on a frame, saving the volume and space occupied by the wire threading mechanism. At the same time, relying on the cooperation of a wire transport mechanism, a wire clamping mechanism, and a wire cutting mechanism, after the prepared wire is pulled into place, the wire of a predetermined length is cut and the wire threading is completed. There is no need to use the prepared wire to press the cut wire, thereby avoiding the influence of the wire threading efficiency in the wire hole due to the misalignment of the prepared wire and the cut wire during wire threading.

[0007] Furthermore, a wire threading method is provided, in which a wire transport mechanism and a wire clamping mechanism cooperate with a brush plate that rotates gradually at a predetermined angle, so that wire threading is completed one by one at each wire hole on the brush plate, thereby improving the wire threading quality and efficiency.

After the wire clamping assembly clamps the traction section, the driving member drives the wire clamping assembly to move downward to pull the prepared wire downward into place. The wire cutting mechanism is arranged between the brush plate and the wire transport mechanism. After the wire clamping mechanism pulls the prepared wire downward into place, the wire cutting mechanism can cut the prepared wire so that the cut wire of a predetermined length is passed into the wire hole into place.

The head of the wire folding frame is the wire folding end, and the wire folding end is provided with a strip groove extending toward the inner side of the wire folding frame.

The wire folding frame is provided with a wire folding cavity running through from top to bottom; the brush disc is inserted into the strip groove, and the corresponding wire hole on the brush disc is in the wire folding cavity; when the cut wire is passed into place in the wire hole, the cut wire is divided into two strands of wire located on both sides of the brush disc, and at this time the wire clamping mechanism releases the traction section, and the driving assembly drives the wire folding frame to move in a direction away from the brush disc, so that the upper wire folding part and the lower wire folding part overlap the two strands of wire outward into a wire bundle; the wire folding mechanism enables the two strands of wire to be quickly overlapped into a wire bundle, thereby improving the wire folding efficiency.

[0014] Preferably, a guide assembly is provided in the wire folding chamber, comprising two opposing guide plates, one of which is connected to a guide cylinder. When the wire transport mechanism transports the prepared wire downward, the piston rod of the guide cylinder extends to bring the two guide plates closer together, forming a guide groove for guiding the prepared wire into the wire hole. When the wire folding frame moves away from the brush plate, the piston rod of the guide cylinder retracts to move the two guide plates apart to avoid the outwardly folded strands of wire. While guiding the wire into the wire hole, the guide assembly also takes into account the problem of the guide plate avoiding the strands of wire during folding, preventing the two strands of wire from interfering with the guide plate when folded in half.

The outer periphery of the wire pressing disc and the periphery of the lower wire pressing disc are evenly distributed with radial slide grooves corresponding to the wire holes one by one, and a radial pressure rod is slidably connected in the radial slide groove. The end surface of the wire pressing disc facing away from the brush disc is evenly distributed with radial guide grooves connected by multiple radial slide grooves along the circumferential direction, and the radial pressure rod is provided with a protrusion that exceeds the end surface of the wire pressing disc facing away from the brush disc and is slidably connected in the radial guide groove; the brush disc divides the two wire pressing discs into an upper wire pressing disc and a lower wire pressing disc The frame is also provided with an upper push-pull rod and a lower push-pull rod located on the upper and lower sides of the brush disc, and the upper push-pull rod and the lower push-pull rod are driven by an upper push-pull cylinder and a lower push-pull cylinder respectively; the upper push-pull rod is on the inner side of the protrusion of the upper wire pressing disc, and the lower push-pull rod is on the inner side of the protrusion of the lower wire pressing disc; when the wire folding frame overlaps the two strands of wire outward into a wire bundle, the upper push-pull cylinder and the lower push-pull cylinder respectively drive the upper push-pull rod and the lower push-pull rod to move in the direction away from the brush disc and act on the corresponding protrusions, so that the corresponding radial pressure rods extend out and press the two strands of wire against the corresponding end faces of the brush disc; ensure that the formed wire bundle remains fixed and does not spread outward, so as to facilitate fixing the wire bundle.

[0016] Preferably, a linkage assembly is provided on the wire folding mechanism, which includes a first support plate and a second support plate that are sequentially away from the wire folding frame, a first cross bar is connected between the first support plate and the second support plate, and the wire folding frame is arranged on the first support plate; the driving assembly includes a first driving cylinder and a second driving cylinder that act on the second support plate, the piston rod of the first driving cylinder is retracted and drives the wire folding frame to move in a radial direction away from the brush plate to make room for the radial pressure rod to extend radially; when the radial pressure rod is extended and presses the stranded wire, the piston rod of the second driving cylinder is retracted and drives the wire folding frame to move in a radial direction away from the brush plate The second driving cylinder can form a step-by-step drive for the second support plate to make up for the response time difference between the driving assembly and the upper push-pull cylinder and the lower push-pull cylinder, so that when the piston rod of the first driving cylinder is extended and retracted to make room for the corresponding radial pressure rod, the two strands of wire are still stuck in the strip groove and do not spread outward. After the radial pressure rod presses the strands of wire, the extension and retraction of the piston rod of the second driving cylinder is completely separated from the formed wire bundle, ensuring that after the wire folding mechanism folds the wire, the corresponding movable pressure rod can smoothly compress the wire bundle.

[0017] Preferably, the wire holes on the brush disc that have not been threaded with wire are divided into wire holes waiting for material, and the wire holes with formed wire bundles are divided into wire holes that have been threaded; it also includes a wire drawing mechanism arranged on the frame, the wire drawing mechanism includes a movable lever and a rotating shaft extending in the longitudinal direction, the rotating shaft is connected to a wire drawing drive member, and the rotating shaft and the movable lever are connected by a linkage rod; the wire drawing drive member can drive the rotating shaft to rotate, and link the movable lever to move between the adjacent wire-threaded holes and the wire holes waiting for material on the brush disc, so as to draw the wire bundles in the wire-threaded holes to one side of the wire-threaded holes; so that the forked wire bundles will not be deflected to the side of the wire hole to be threaded when the wire is threaded into the next wire hole to be threaded, so that the wire in the next wire hole to be threaded and folded can be smoothly threaded and folded, and the formed wire bundles are prevented from being drawn into the next formed wire bundles.

[0018] Preferably, the wire drawing mechanism also includes a fixed drawing rod adjacent to the movable drawing rod; when the support shaft rotates and the last wire hole to be fed on the brush disc is threaded, wire bundles are formed in the two wire-threaded holes adjacent to the wire hole to be fed, and the wire drawing drive drives the rotating shaft to rotate, so that the movable drawing rod moves to between one of the wire-threaded holes and the wire hole to be fed, and draws together the wire bundles on one side of one of the wire-threaded holes. At this time, the fixed drawing rod is between the other wire-threaded hole and the wire hole to be fed, and draws together the wire bundles on the other side of the wire-threaded hole.

[0019] A threading method comprises the following steps: S1: The wire transport mechanism transports the prepared wire downward, and the lower end of the prepared wire passes through one of the wire holes of the brush plate to form a traction section that exceeds the lower end surface of the brush plate; S2: The wire clamping mechanism clamps the traction section, and the driving member drives the wire clamping mechanism downward to pull the prepared wire downward to a predetermined position; S3: The wire cutting mechanism cuts the prepared wire so that the cut wire of the predetermined length is passed through the wire hole in place; S4: Rotate the brush plate and align the next wire hole on the brush plate with the prepared wire; S5: Repeat steps S1-S4 in sequence until all the wire holes on the brush plate are threaded with wire.

[0020] The beneficial effects of the present invention using the above technical solution are: The wire threading mechanism in the present invention can transport the prepared wire into the wire hole of the brush disc through the wire transport mechanism, and form a traction section at the lower end of the brush disc, and then use the wire clamping mechanism to pull the traction section downward into place, and use the wire cutting mechanism to cut the wire of a predetermined length, thereby completing the wire threading process in the wire hole. The whole process adopts the method of first threading and then cutting. Compared with the method of first cutting and then threading in the background technology, there will be no misalignment between the cut wire and the prepared wire, and the reliability and efficiency of wire threading are higher.

[0021] In the entire wire threading mechanism, the wire transport mechanism, the wire cutting mechanism and the wire clamping mechanism are arranged longitudinally above or below the brush disc, so that the space occupied by the entire wire threading mechanism is lower, and the layout of the entire wire threading mechanism is optimized.

[0022] The wire folding frame arranged on the frame can drive the wire folding frame away from the brush plate through the driving component after the cut wire is passed through the wire hole, so that the upper wire folding part and the lower wire folding part respectively fold the strands of wire on both sides of the brush plate outward into a wire bundle. The design is simple and ingenious, which improves the efficiency of wire bundle forming.

[0023] After the filament bundle is formed, the brush plate can cooperate with the upper push-pull rod and the lower push-pull rod through the wire pressing assembly, so that the radial pressure rods on the upper wire pressing disc and the lower wire pressing disc extend and press the stranded wire on both sides of the brush plate to prevent the stranded wire from spreading outward due to its own elasticity, making it easier to fix the filament bundle in the next step.

[0024] When threading and folding wires, the wire pulling mechanism in the present invention can pull the wire bundle on the side of the threaded wire hole outwards, so that the wire threading, wire folding and other operations can be carried out normally at the wire hole for waiting material that has not been threaded, thereby avoiding the wire bundle on the side of the threaded wire hole from bifurcation due to its own elastic force and causing it to be entangled in the wire bundle on the side of the wire hole for waiting material, thereby improving the stability of the wire threading and wire folding process.

At the same time, the lower wire transport cylinder 321 can drive the wire transport part 313 in the lower wire transport assembly 32 to move downward, so that the lower end of the prepared wire 7 is to the upper end of the wire hole 91, so as to be ready before the wire transport mechanism 33 starts to transport the wire.

[0031] Further, if Figure 3 As shown, the structure of the slitting mechanism 36 is as follows: the slitting mechanism 36 includes a fixed cutter 363 and a movable cutter 361 which are arranged on the frame 3 and are horizontally opposite to each other. The movable cutter 361 is connected to a slitting cylinder 362. When the prepared wire 7 is pulled downward into place by the wire clamping mechanism 39, the slitting cylinder 362 drives the movable cutter 361 to approach the fixed cutter 363 to cut the prepared wire 7.

[0036] Furthermore, after the cut wire 8 is passed through the wire hole 91, the brush plate 2 divides the cut wire 8 into two strands located on both sides of the brush plate 9. In order to fold the two strands outward, a wire folding mechanism 37 is provided on the frame 3.

The strip groove 375 divides the wire folding end into an upper wire folding portion 375a and a lower wire folding portion 375b. The wire folding frame 371 has a A wire folding cavity running through the upper and lower parts; the brush disc 9 is inserted into the strip groove 375, and the corresponding wire hole 91 on the brush disc 9 is in the wire folding cavity; when the cut wire 8 is passed into the wire hole 91, the cut wire 8 is divided into two strands of wire located on both sides of the brush disc 9. At this time, the wire clamping mechanism 39 releases the traction section 71, and the driving component drives the wire folding frame 371 to move away from the brush disc 9, so that the upper wire folding part 375a and the lower wire folding part 375b fold the two strands of wire outward into a wire bundle; the wire folding mechanism 37 enables the two strands of wire to be quickly folded into a wire bundle, thereby improving the wire folding efficiency.

[0037] Further, if Figure 1 As shown, a guide assembly is provided in the wire folding cavity, which includes two opposing guide plates 372, one of which is connected to a guide cylinder 374; when the wire transport mechanism 33 transports the prepared wire 7 downward, the piston rod of the guide cylinder 374 extends to bring the two guide plates 372 closer together to form a guide groove 373 for guiding the prepared wire 7 to pass into the wire hole 91; when the wire folding frame 371 moves in a direction away from the brush plate 9, the piston rod of the guide cylinder 374 retracts to move the two guide plates 372 away to avoid the outwardly overlapping stranded wire. The guide assembly of this embodiment, while guiding the wire to pass into the wire hole, takes into account the problem of the guide plate avoiding the stranded wire when folding the wire, thereby controlling one of the guide plates 372 to move through the guide cylinder 374, effectively preventing the two strands of wire from interfering with the guide plate 372 when folded in half.

[0038] Furthermore, when a guide assembly is provided in the wire folding cavity, the guide plate 372 is likely to interfere with the brush disc 9. Therefore, the two guide plates 372 in this embodiment are provided with avoidance grooves (not shown) corresponding to the strip grooves 375 and used to avoid the brush disc 9. The avoidance grooves divide the entire guide plate 372 into two guide support plates. The avoidance grooves can prevent the guide plate 372 from interfering with the brush disc inserted into the strip grooves 375, thereby allowing the wire folding work to proceed smoothly.

[0039] Further, if Figure 10As shown, in order to ensure that the brush disc 9 can rotate circumferentially along its own axis and to compress and fix the wire bundle after folding, the brush disc 9 is arranged on a wire pressing assembly, and a plurality of wire holes 91 on the end face of the brush disc 9 form a pair of matching areas. The wire pressing assembly includes a support shaft 636 that can rotate along the circumferential direction. The top of the support shaft 636 is provided with two wire pressing discs that are matched on the upper and lower sides of the brush disc 9 and are in the matching area. The outer periphery of the wire pressing disc and the outer periphery of the lower wire pressing disc 638 are evenly distributed with wire holes 91 corresponding to each other. The radial slide 631b is connected to the radial pressure rod 633 in a sliding manner. The end surface of the wire pressing disc facing away from the brush disc 9 is uniformly distributed along the circumference with a plurality of radial guide grooves 632 connected by the radial slide 631b. The radial pressure rod 633 is provided with a protrusion 634 that exceeds the end surface of the wire pressing disc facing away from the brush disc 9 and is slidably connected to the radial guide groove 632. The brush disc 9 divides the two wire pressing discs into an upper wire pressing disc 631 and a lower wire pressing disc 638. The frame 3 is also provided with a protrusion 634 located on the brush disc 9. The upper push-pull rod 341 and the lower push-pull rod 351 on the upper and lower sides are driven by an upper push-pull cylinder 342 and a lower push-pull cylinder 353 respectively; the upper push-pull rod 341 and the upper push-pull cylinder 342 constitute an upper push-pull assembly 34; the lower push-pull rod 351 and the lower push-pull cylinder 353 constitute a lower push-pull assembly 35; the upper push-pull rod 341 is located on the inner side of the protrusion 634 of the upper wire pressing disk 631, and the lower push-pull rod 351 is located on the inner side of the protrusion 634 of the lower wire pressing disk 638 The inner side of the protrusion 634; when the wire folding frame 371 folds the two strands of wire outward into a wire bundle, the upper push-pull cylinder 342 and the lower push-pull cylinder 353 respectively drive the upper push-pull rod 341 and the lower push-pull rod 351 to move in the direction away from the brush disc 9 and act on the corresponding protrusion 634, so that the corresponding radial pressure rod 633 extends and presses the two strands of wire tightly on the corresponding end face of the brush disc 9; ensuring that the formed wire bundle remains fixed and does not spread outward, so as to facilitate the fixing of the wire bundle.

[0040] Further, if Figure 7As shown, the structure of the wire folding mechanism 37 is as follows: a linkage assembly is provided on the wire folding mechanism 37, the linkage assembly includes a first support plate 374a and a second support plate 374b which are sequentially away from the wire folding frame 371, a first cross bar 377 is connected between the first support plate 374a and the second support plate 374b, and the wire folding frame 371 is arranged on the first support plate 374a; a driving assembly includes a first driving cylinder 376 and a second driving cylinder 379 which act on the second support plate 374b, the piston rod of the first driving cylinder 376 is retracted and drives the wire folding frame 371 to move in a radial direction away from the brush plate 9 to make room for the radial pressure rod 633 to extend radially; when the radial pressure rod 633 is extended and presses the divided wire, the piston rod of the second driving cylinder 379 is extended The first drive cylinder 376 and the second drive cylinder 379 can form a step-by-step drive on the second support plate 374b to make up for the response time difference between the drive assembly and the upper push-pull cylinder 342 and the lower push-pull cylinder 353, so that when the piston rod of the first drive cylinder 376 is extended and retracted to make room for the corresponding radial pressure rod 633, the two strands of wire are still stuck in the strip groove 375 and do not spread outward. After the radial pressure rod 633 compresses the strands of wire, the piston rod of the second drive cylinder 376 is extended and retracted to completely separate from the formed wire bundle, ensuring that after the wire folding mechanism 37 folds the wire, the corresponding movable pressure rod 633 can smoothly compress the wire bundle.

[0041] Furthermore, since the wire hole 91 of the brush disc 9 is close to the outer peripheral edge of the brush disc 9, the two strands of wire can be folded in half to form a wire bundle that extends beyond the outer periphery of the brush disc, and after the wire bundle is formed, the length of the stranded wire attached to the end face of the brush disc 9 is smaller than the length of the stranded wire extending beyond the brush disc 9. Therefore, to correspond to these two lengths, the telescopic stroke of the piston rod of the first drive cylinder 376 is smaller than the telescopic stroke of the piston rod of the second drive cylinder 379. Specifically, when the piston rod of the first drive cylinder 376 is telescopic and drives the wire folding frame 371 to move in a radial direction away from the brush disc 9 and makes room for the movable pressure rod 633 to extend radially, the wire folding end only needs to just leave the end face of the brush disc 9, so the range of movement of the wire folding frame 371 at this time is shorter; afterwards, the wire folding frame 371 needs to be completely separated from the wire bundle, and the required range of movement is longer, so the telescopic length of the piston rod of the second drive cylinder 379 is longer.

[0042] Furthermore, if the first drive cylinder 376 and the second drive cylinder 379 are arranged side by side to drive the wire folding frame 371 in steps, then when the first drive cylinder 376 or the second drive cylinder 379 is extended or retracted, the piston rod of the other cylinder will inevitably be driven to move, affecting the smoothness of the movement of the wire folding frame 371. Therefore, in order to meet the purpose of driving the wire folding frame 371 in steps, the first drive cylinder 376 is arranged on the first support plate 374a, and the second drive cylinder 379 is arranged on the first longitudinal plate 378 close to the side of the first support plate 374a, and the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379 are relative and connected together; specifically, there is a shaft sleeve between the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379, and the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379 are inserted into the shaft sleeve and locked by screws; thereby, while meeting the step-by-step drive of the wire folding frame 374, the layout space of the drive component is saved.

[0043] Further, if Figure 15 As shown, at the outer periphery of the wire pressing disk, a limiting portion 631a is formed between every two adjacent radial slots 631b, and the movable pressure rod 633 has two opposite side extensions 633a on both sides. When the movable pressure rod 633 is retracted, the two side extensions 633a are abutted against the corresponding limiting portions 631a to prevent the entire movable pressure rod 633a from being completely retracted into the radial slot 631b.

[0044] Furthermore, the bottom end of the movable pressure rod 633 has a limiting groove 635. After the movable pressure rod 633 is extended, the stranded wire is within the limitation of the limiting groove 635, preventing the stranded wire from spreading to both sides.

[0045] Furthermore, a plurality of weight-reducing grooves 631c are provided on the end surface of the wire pressing disc, which are through-through and evenly distributed along the circumferential direction, so as to make the structure of the entire wire pressing disc 631 lighter.

[0046] Further, if Figure 2As shown, the specific structure of the upper push-pull assembly 34 is as follows: a horizontal plate 343 for installing the upper push-pull assembly 34 is provided on the frame 3, and a avoidance hole 344 for avoiding the guide tube 324 is provided on the horizontal plate 343. The upper push-pull assembly 34 includes a first vertical plate 346 set on the support frame 3, and the upper driving member is an upper push-pull cylinder 342 connected to the first vertical plate 346. The piston rod of the upper push-pull cylinder 342 is connected to the upper push-pull member 341; in order to ensure the smooth movement of the upper push-pull rod 341, a first vertical plate 346 is provided for installing The connecting plate 345 of the upper push-pull member 341 is provided with a second guide assembly between the connecting plate 345 and the first vertical plate 346. The second guide assembly includes a second cross bar 344. The connecting plate 345 is provided with a second guide hole matching the second cross bar 344. The second guide holes are symmetrically arranged on the connecting plate 345. The number and position of the second cross bar 344 match those of the second guide holes. One end of the second cross bar 344 acts on the upper push-pull member 341, and the other end passes through the second guide hole, thereby guiding the lifting activity of the upper push-pull member 341.

[0047] Further, if Figure 8 As shown, the specific structure of the lower push-pull assembly 35 is as follows: the lower push-pull assembly 35 includes two mounting plates 352 arranged at intervals on the support frame 3, and a third cross bar 355 is connected between the two mounting plates 352; the lower push-pull member 351 is installed on the mounting plate 352 on the side close to the wire folding frame 371, and the second driving member is a lower push-pull cylinder 353 acting on the mounting plate 352 on the side away from the wire folding frame 371; to ensure smooth movement of the lower push-pull rod 351, a second vertical plate 354 for mounting the lower push-pull cylinder 353 is provided on the support frame 3, and a third guide hole for sliding cooperation with the third cross bar 355 is provided on the second vertical plate 354; the third guide holes are symmetrically arranged on the second vertical plate 354, and the number and position of the third cross bar 355 match the third guide holes; to guide the lifting movement of the lower push-pull member 351.

[0048] Furthermore, the wire holes 91 on the brush plate 9 that are not threaded with wire are classified as waiting wire holes, and the wire holes 91 that have formed a wire bundle are classified as threaded wire holes; Figure 11-13As shown, in order to ensure that the wire bundle at the wire-threaded hole will not be deflected toward the wire-threaded hole after bifurcation due to its own elasticity, the wire-threading mechanism also includes a wire-drawing mechanism 38 arranged on the frame 3, and the wire-drawing mechanism 38 is arranged at the side position of the wire clamping seat 396 in the wire clamping mechanism 39, and the wire-drawing mechanism 38 can move synchronously with the wire clamping mechanism 39 to approach or move away from the lower end of the brush plate 9; the wire-drawing mechanism 38 includes a movable lever 381 and a rotating shaft 382 extending in the longitudinal direction, and the rotating shaft 382 is connected to the movable lever 381, and the rotating shaft 382 is connected to the movable lever 381 through a linkage rod 383; the wire-drawing drive member can drive the rotating shaft 382 to rotate, and link the movable lever 381 to move between the adjacent wire-threaded hole and the wire-threaded hole to be fed on the brush plate 9, so as to draw the wire bundle in the wire-threaded hole to one side of the wire-threaded hole; so that the wire in the next wire-threaded hole to be fed can be smoothly threaded and folded, thereby avoiding the formed wire bundle from being entangled in the next formed wire bundle.

[0049] Furthermore, the specific structure of the wire drawing mechanism 38 is as follows: the wire drawing driving member can be directly connected to the rotating shaft 1 to drive the movable drawing rod 381 to move, or the driving member can be indirectly connected to the rotating shaft 1 through a transmission assembly; in this embodiment, the rotating shaft 382 is arranged on a wire drawing seat 386, and the wire drawing seat 386 is provided with a transmission assembly. The transmission assembly includes a transmission rod 388 slidably connected to the wire drawing seat 386, and the transmission rod 388 is provided with a plurality of tooth grooves 389. A swinging tooth member 387 is fixedly connected to the shaft body of the rotating shaft 1, and the swinging tooth member 387 has a plurality of tooth portions 387a matching the tooth grooves 389. The driving member is a wire drawing cylinder 384, and the piston rod of the wire drawing cylinder 384 is indirectly connected to the transmission rod 388 through a transition connecting plate 385. The piston rod of the wire drawing cylinder 384 can drive the transmission rod 388 to slide on the wire drawing seat 386 by retracting and extending, so that the tooth grooves 389 cooperate with the tooth portions 387a to drive the rotating shaft 1 to rotate.

[0050] Furthermore, compared with providing a standard tooth groove on the rod body of the transmission rod 388, the transmission rod 388 in this embodiment has lower cost and is easier to process, that is, the transmission rod 388 is a screw rod, and the tooth groove 389 is a spiral groove arranged on the screw rod; compared with providing a standard tooth groove on the transmission rod 388, directly using a screw rod with a spiral groove has lower cost, and at the same time can also ensure the meshing effect of the tooth groove 389 and the tooth portion 387a.

[0051] Furthermore, the volume of the wire drawing mechanism 38 needs to be miniaturized, and the miniaturized wire drawing mechanism 38 is easier to install in the corresponding position of the wire threading mechanism. Therefore, in this embodiment, a accommodating chamber 3861 is provided on the wire drawing seat 386, and the rotating shaft 1 has a matching portion that is penetrated in the accommodating chamber 3861, and the matching portion is fixedly connected to the swinging tooth 387, and the side wall of the accommodating chamber 3861 is provided with a sliding guide hole 3862 that communicates with the outside world, and the transmission rod 388 is slidably connected in the sliding guide hole 3862; the accommodating chamber 3861 can accommodate the transmission assembly in the wire drawing seat 386, reduce the space it occupies in the wire drawing mechanism, optimize the structural layout of the wire drawing mechanism, and facilitate the installation of the wire drawing mechanism to the wire threading mechanism for wire drawing.

[0052] Furthermore, the connection relationship between the transition connecting plate 385, the transmission rod 388, and the wire drawing cylinder 384 is as follows: the transition connecting plate 385 is provided with a connecting sleeve inserted into the sliding guide hole 3862, and the end of the transmission rod 388 is provided with a screw hole corresponding to the position of the connecting sleeve. The screw passes through the connecting sleeve and is screwed into the screw hole to connect the transmission rod 388 to the transition connecting plate 385; a threaded rod is connected to the piston rod of the wire drawing cylinder 384, and an internal threaded sleeve corresponding to the threaded rod is connected to the transition connecting plate 385. After the threaded rod and the internal threaded sleeve are matched, they are locked by a nut to connect the piston rod to the transition connecting plate 385.

[0053] Furthermore, when multiple holes for wire to be fed are threaded and folded one by one, it is only necessary to control the movable lever 381 to pull together the wire bundles at the adjacent holes that have been threaded. However, when the last hole for wire to be fed is threaded and folded, the wire holes on both sides of the last hole for wire to be fed have been threaded and formed into wire bundles, so another lever is required to cooperate with the movable lever 381; Figure 14 As shown, the wire-drawing mechanism 38 in this embodiment also includes a fixed lever 38a adjacent to the movable lever 381; when the support shaft 636 rotates and causes the last wire-waiting hole on the brush plate 9 to be threaded, wire bundles are formed in the two wire-threaded holes adjacent to the wire-waiting hole, and the wire-drawing drive member drives the rotating shaft 382 to rotate, so that the movable lever 381 moves to between one of the wire-threaded holes and the wire-waiting hole, and draws together the wire bundles on one side of one of the wire-threaded holes. At this time, the fixed lever 38a is between the other wire-threaded hole and the wire-waiting hole, and draws together the wire bundles on the other side of the wire-threaded hole.

[0054] Based on the wire threading mechanism, this embodiment provides a wire threading method, including the following steps: S1: The wire transport mechanism 33 transports the prepared wire 7 downward, and causes the lower end of the prepared wire 7 to pass through one of the wire holes 91 of the brush plate 9 to form a traction section 71 that extends beyond the lower end surface of the brush plate 9; S2: The wire clamping mechanism 39 clamps the pulling section 71, and the driving member drives the wire clamping mechanism 39 to move downward to pull the prepared wire 7 downward to a predetermined position; S3: The cutting mechanism 36 cuts the prepared wire 7 so that the cut wire 8 of a predetermined length is inserted into the wire hole 91 in place; S4: Rotate the brush plate 9 and align the next wire hole 91 on the brush plate 9 with the prepared wire 7; S5: Repeat steps S1-S4 in sequence until all the wire holes 91 on the brush disc 9 are threaded with wire. Through this threading method, the wire is threaded one by one in each wire hole 91 on the brush disc 9, thereby improving the threading quality and efficiency, and facilitating efficient threading of multiple brush discs 9 in batches on the threading mechanism.

[0055] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
