Description

Technical Field

[0001] This utility model relates to the field of strip grinding, and in particular to a wire threading mechanism. Background Technology

[0002] Strip steel is typically manufactured using a hot-rolling process. Before actual use, rust and oxide scale may form on the surface of the strip steel, requiring brushing and polishing with a brush roller. To facilitate disassembly and maintenance, an existing brush roller structure is configured with multiple abrasive discs mounted on a roller shaft. Each abrasive disc includes a brush plate, and the inner side of the brush plate has multiple circumferentially distributed filament holes. Multiple parallel filaments made of resin material are threaded through the filament holes. These parallel filaments are folded in half radially away from the brush plate, forming two strands of filaments on either side of the brush plate. The two strands of filaments are fixed together to form a bundle of filaments for polishing the surface of the strip steel.

[0003] The manual threading method is too inefficient. To improve the threading efficiency, the applicant previously designed a threading mechanism patent with publication number CN112353088, which adopts a horizontal layout structure. After the thread conveying mechanism transports the prepared wire forward, the wire cutting mechanism cuts the prepared wire to obtain a cut wire of a predetermined length. Then, the thread conveying mechanism continues to transport the wire and pushes the cut wire into the wire hole of the brush plate, so that the two ends of the cut wire are located on both sides of the brush plate. However, this threading mechanism has shortcomings.

[0004] The entire threading mechanism, including the thread conveying mechanism and the thread cutting mechanism, adopts a horizontal layout, which requires a large layout space.

[0005] When the slicing mechanism cuts and forms the cut wire, the cut wire is 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 easily deforms and spreads outward after being subjected to force, which can easily lead to misalignment between the prepared wire and the cut wire, affecting the wire threading quality and efficiency. Summary of the Invention

[0006] This utility model provides a wire threading mechanism. The various working mechanisms on the threading mechanism are arranged longitudinally on the frame, saving the volume and space occupied by the threading mechanism. At the same time, relying on the cooperation of the wire conveying mechanism, the wire clamping mechanism, and the wire cutting mechanism, after the prepared wire is pulled into place, the wire of the predetermined length is cut and the threading is completed. It is not necessary to press the cut wire with the prepared wire, thus avoiding the threading efficiency in the wire hole due to misalignment between the prepared wire and the cut wire during the threading process.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A wire threading mechanism, comprising:

[0009] Frame; support components configured for the wire threading mechanism;

[0010] Brush disk; The brush disk itself has a vertical axis and can rotate along its own axis. Multiple wire holes are evenly distributed circumferentially on the end face of the brush disk.

[0011] The wire conveying mechanism is located above the brush plate. It can transport the prepared wire from top to bottom and make the prepared wire pass through one of the wire holes of the brush plate to form a traction section that extends beyond the lower end face of the brush plate.

[0012] The wire clamping mechanism is located below the brush plate and includes a drive unit and a wire clamping assembly corresponding to the position of the traction section. After the wire clamping assembly clamps the traction section, the drive unit drives the wire clamping assembly to move downward to pull the prepared wire into place.

[0013] The shredding mechanism is located between the brush plate and the shredding mechanism. After the shredding mechanism pulls the prepared shredding material downward into place, the shredding mechanism can cut the prepared shredding material, so that the cut shredding material of the predetermined length is inserted into the shredding hole.

[0014] Preferably, the wire feeding mechanism includes a wire feeding assembly arranged on the frame. The wire feeding assembly includes a wire feeding component with a through-hole for receiving pre-loaded wire. A clamping cylinder is connected to the wire feeding component. The clamping cylinder has a telescopic pressure rod inserted into the through-hole for clamping or releasing the pre-loaded wire. There are two wire feeding assemblies, including an upper wire feeding assembly and a lower wire feeding assembly arranged sequentially on the frame. The upper wire feeding assembly is connected to an upper wire feeding cylinder and is driven by the upper wire feeding cylinder to move longitudinally along its lower edge. When the telescopic pressure rod in the upper wire feeding assembly extends to clamp and transport the pre-loaded wire downward, the telescopic pressure rod in the lower wire feeding assembly retracts. When the telescopic pressure rod in the upper wire feeding assembly retracts to release the pre-loaded wire and return to its original position, the telescopic pressure rod in the lower wire feeding assembly extends to clamp the pre-loaded wire. This process is repeated alternately until the lower end face of the brush plate forms the traction section. The wire feeding mechanism can stably transport the pre-loaded wire downward in an alternating transport manner, ensuring that the lower end face of the brush plate forms the traction section.

[0015] Preferably, the lower wire feeding assembly is driven by a lower wire feeding cylinder and moves longitudinally. The wire feeding component in the lower wire feeding assembly is connected to a downwardly extending guide tube, and the wire inlet hole on the wire feeding component in the lower wire feeding assembly is set on the guide tube. Before the upper wire feeding assembly is driven by the upper wire feeding cylinder, the telescopic pressure rod in the lower wire feeding assembly extends and presses the prepared wire in the guide tube. The lower wire feeding cylinder drives the lower wire feeding assembly to move downward so that the lower end of the guide tube is aligned with the corresponding wire hole on the brush plate. While guiding the wire into the wire hole, the guide tube can restrict the wire that is passing through the wire inlet hole to be inside the tube, preventing the wire that is passing through the wire inlet hole from spreading outward. At the same time, the lower wire feeding cylinder can drive the wire feeding component in the lower wire feeding assembly to move downward so that the lower end of the prepared wire is at the upper end of the wire hole, so as to prepare before the wire feeding mechanism starts feeding.

[0016] Preferably, the shredding mechanism includes a fixed cutter and a movable cutter mounted on the frame and horizontally opposite each other. A shredding cylinder is connected to the movable cutter. When the prepared shreds are pulled downward into place by the shredding mechanism, the shredding cylinder drives the movable cutter to approach the fixed cutter to cut the prepared shreds.

[0017] Preferably, the wire clamping mechanism includes a wire clamping base and a wire clamping assembly, and the driving component is a wire clamping cylinder connected to the lower end of the wire clamping base; the wire clamping assembly includes a first wire clamping member and a second wire clamping member disposed on the wire clamping base, at least one of the first wire clamping member and the second wire clamping member is connected to a clamping cylinder, the clamping cylinder drives the first wire clamping member and / or the second wire clamping member to move to clamp the traction section, and then the wire clamping cylinder drives the wire clamping assembly to move downward to pull the prepared wire downward into place.

[0018] Preferably, the frame is equipped with a wire folding mechanism, which includes a wire folding frame and a drive assembly for horizontally moving the wire folding frame. The head of the wire folding frame is the wire folding end, and the wire folding end has a strip groove extending inward from the wire folding frame. The strip groove divides the wire folding end into an upper wire folding part and a lower wire folding part. The wire folding frame has a wire folding cavity that runs vertically through it. The brush plate is inserted into the strip groove, and the corresponding wire hole on the brush plate is located in the wire folding cavity. When the cut wire is inserted into the wire hole, the cut wire is divided into two strands of wire located on both sides of the brush plate. At this time, the wire clamping mechanism releases the traction section, and the drive assembly drives the wire folding frame to move away from the brush plate, 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.

[0019] Preferably, the folding cavity is equipped with a guiding assembly, which includes two opposing guide plates, one of which is connected to a guiding cylinder. When the wire feeding mechanism transports the prepared wire downwards, the piston rod of the guiding cylinder extends, bringing the two guide plates closer together to form a guiding groove for guiding the prepared wire into the wire hole. When the folding frame moves away from the brush plate, the piston rod of the guiding cylinder retracts, moving the two guide plates apart to avoid the outwardly overlapping strands of wire. While guiding the wire into the wire hole, the guiding assembly also considers the issue of the guide plate avoiding the strands of wire during folding, preventing interference between the two strands of wire and the guide plate when folded.

[0020] Preferably, the brush disc is mounted on a wire pressing assembly. Multiple wire holes on the end face of the brush disc form a mating area. The wire pressing assembly includes a circumferentially rotatable support shaft. The top of the support shaft has two wire pressing discs mating with the upper and lower sides of the brush disc and located within the mating area. Radial grooves corresponding one-to-one with the wire holes are evenly distributed on the outer periphery of both the upper and lower wire pressing discs. Radial pressure rods are slidably connected within these radial grooves. Multiple radial guide grooves communicating with the radial grooves are evenly distributed circumferentially on the end face of the wire pressing disc facing away from the brush disc. The radial pressure rods have protrusions extending beyond the end face of the wire pressing disc facing away from the brush disc and slidably connected within the radial guide grooves. 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 equipped with upper and lower push-pull rods located on the upper and lower sides of the brush disc. The upper and lower push-pull rods are driven by an upper push-pull cylinder and a lower push-pull cylinder, respectively. The upper push-pull rod is located inside the protrusion of the upper pressure plate, and the lower push-pull rod is located inside the protrusion of the lower pressure plate. When the folding frame overlaps the two strands of material into a bundle, the upper and lower push-pull cylinders drive the upper and lower push-pull rods to move away from the brush disc and act on the corresponding protrusions, so that the corresponding radial pressure rods extend and press the two strands of material onto the corresponding end faces of the brush disc. This ensures that the formed bundle remains fixed and does not spread outward, so as to fix the bundle.

[0021] Preferably, the wire bending mechanism is equipped with a linkage component, which includes a first support plate and a second support plate that move away from the wire bending frame in sequence. A first crossbar connects the first and second support plates, and the wire bending frame is mounted on the first support plate. The driving component 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 extends and retracts, driving the wire bending frame to move radially away from the brush plate, so as to make room for the radial pressure rod to extend radially. When the radial pressure rod extends and presses the stranded wires, the piston rod of the second driving cylinder extends and retracts, driving the wire bending frame to move radially away from the brush plate. The direction continues to move, so that the folding frame is completely separated from the filament bundle; the first and second drive cylinders can drive the second support plate in steps to compensate for the response time difference between the drive assembly and the upper and lower push-pull cylinders. When the piston rod of the first drive cylinder extends and retracts to make room for the corresponding radial pressure rod, the two strands of filament are still stuck in the strip groove and do not spread outward. After the radial pressure rod presses the strands of filament, the extension and retraction of the piston rod of the second drive cylinder completely disengages from the formed filament bundle, ensuring that after the folding mechanism folds the filament, the corresponding movable pressure rod can smoothly press the filament bundle.

[0022] Preferably, the unthreaded wire holes on the brush are designated as wire-waiting holes, and the wire holes with wire bundles are designated as threaded holes. The brush also includes a wire-pulling mechanism mounted on the frame. This mechanism comprises a longitudinally extending movable lever and a rotating shaft. A wire-pulling drive is connected to the rotating shaft, and the rotating shaft and the movable lever are connected via a linkage. The wire-pulling drive can drive the rotating shaft to rotate and move the movable lever to the space between adjacent threaded holes and wire-waiting holes on the brush, thus drawing the wire bundles in the threaded holes to one side. This prevents the forked wire bundles from deflecting to one side of the next wire-waiting hole when threaded, allowing for smooth threading and bending of the wire bundles in the next wire-waiting hole, and preventing the formed wire bundles from being rolled into the next formed wire bundle.

[0023] Preferably, the wire drawing mechanism also includes a fixed lever adjacent to the movable lever; when the support shaft rotates and the last wire hole on the brush is threaded, wire bundles are formed in the two wire holes adjacent to the wire hole. The wire drawing drive drives the rotating shaft to rotate, causing the movable lever to move between one of the wire holes and the wire hole, and gathers the wire bundle on one side of the wire hole. At this time, the fixed lever is between the other wire hole and the wire hole, and gathers the wire bundle on the other side of the wire hole.

[0024] The beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0025] The threading mechanism of this invention can transport the prepared filament to the filament hole of the brush plate through the filament conveying mechanism, and form a traction section at the lower end of the brush plate. Then, the traction section is pulled downward into place by the filament clamping mechanism, and the filament of the predetermined length is cut by the filament cutting mechanism, thereby completing the threading process in the filament hole. The whole process adopts the method of threading first and then cutting. Compared with the method of cutting first and then threading in the prior art, there will be no misalignment between the cut filament and the prepared filament, and the reliability and efficiency of threading are higher.

[0026] In the entire threading mechanism, the thread conveying mechanism, the thread cutting mechanism, and the thread clamping mechanism are arranged longitudinally above or below the brush plate, which makes the entire threading mechanism occupy less space and optimizes the layout of the entire threading mechanism.

[0027] The wire bending frame mounted on the frame can be driven away from the brush plate by the drive component after the wire is cut and passed through the wire hole. This allows the upper and lower wire bending parts to fold the stranded wires 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.

[0028] After the filament bundle is formed, the brush can cooperate with the upper and lower push-pull rods through the filament pressing assembly to extend the radial pressure rods on the upper and lower filament pressing plates and press the stranded filaments on both sides of the brush, preventing the stranded filaments from spreading outward due to their own elasticity, which facilitates the next step of fixing the filament bundle.

[0029] When threading and folding wires, the wire pulling mechanism in this invention can pull the wire bundle on the threaded side outwards, so that the wire waiting hole can be threaded and folded normally. This avoids the wire bundle on the threaded side from splitting due to its own elasticity and getting caught in the wire bundle on the waiting hole side, thus improving the stability of the threading and folding process.

Detailed Implementation

[0047] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] This utility model has multiple embodiments, the specific embodiments of which are as follows:

[0050] like Figure 1-16 As shown, this embodiment provides a wire threading mechanism, including:

[0051] Frame 3; Support component configured as the wire threading mechanism;

[0052] Brush 9; The axis of brush 9 is vertical and can rotate along its own axis. Multiple wire holes 91 are evenly distributed circumferentially on the end face of brush 9.

[0053] The wire conveying mechanism 33 is located above the brush plate 9. The wire conveying mechanism 33 can transport the prepared wire 7 from top to bottom and make the prepared wire 7 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 face of the brush plate 9.

[0054] The wire clamping mechanism 39 is located below the brush plate 9 and includes a drive unit and a wire clamping assembly corresponding to the position of the traction section 71. After the wire clamping assembly clamps the traction section 71, the drive unit drives the wire clamping assembly to move downward to pull the pre-cut wire 7 into place; thereby transporting the pre-cut wire 7 of a predetermined length into place in one go.

[0055] The shredding mechanism 36 is located between the brush plate 9 and the shredding mechanism 33. After the shredding mechanism 39 pulls the prepared shredding 7 downward into place, the shredding mechanism 36 can cut the prepared shredding 7, so that the cut shredding 8 of a predetermined length is inserted into the shredding hole 91. The cut shredding 8 inserted into the shredding hole 91 fits tightly against the inner wall of the shredding hole 91 and will not fall out of the shredding hole 91 under the action of gravity.

[0056] Furthermore, the frame 3 is equipped with a guide wheel 3b, and the outer circumference of the guide wheel 3b is provided with multiple annular guide grooves, in which multiple wires are located; the wire conveying mechanism 33 includes a wire conveying assembly arranged on the frame 3, the wire conveying assembly including a wire conveying component 313, the wire conveying component 313 having a through-hole 316 for receiving the pre-prepared wire 7, after being guided by the guide grooves, the lower end of the pre-prepared wire 7 passes through the wire conveying hole, the wire conveying component 313 is connected to a clamping cylinder 314, the clamping cylinder 314 having a telescopic pressure rod 315 inserted into the wire conveying hole 316 for clamping or releasing the pre-prepared wire 7; there are two wire conveying assemblies, including an upper wire conveying assembly 31 and a lower wire conveying assembly 32 arranged sequentially on the frame 3, the upper wire conveying assembly 31 being connected to an upper wire conveying cylinder 311, the wire conveying component 313 in the upper wire conveying assembly 31 being connected to The frame 3 has a wire guide rod 312, and a support plate 3a is provided on the top of the frame 3 for mounting the upper wire guide cylinder 311. The wire guide rod 312 is slidably connected in the guide hole provided in the support plate 3a. It is driven by the upper wire guide cylinder 311 to move longitudinally along the lower edge. When the telescopic pressure rod 315 in the upper wire guide assembly 31 extends to press and transport the prepared wire 7 downward, the telescopic pressure rod 315 in the lower wire guide assembly 32 retracts. When the telescopic pressure rod 315 in the upper wire guide assembly 31 retracts to relax the prepared wire 7 and reset upward, the telescopic pressure rod 315 in the lower wire guide assembly 32 extends to press the prepared wire 7. This process is repeated alternately until the lower end face of the brush 9 forms the traction section 71. The wire guide mechanism 33 can stably transport the prepared wire 7 downward in an alternating transport manner to ensure that the lower end face of the brush 9 forms the traction section 71.

[0057] Furthermore, such as Figure 4-6As shown, the lower wire feeding assembly 32 is driven by a lower wire feeding cylinder 321 and moves longitudinally. Specifically, the frame 3 is provided with a hook plate 322 for easy connection. The hook plate 321 is mounted on a sliding plate 323, which is slidably connected to a longitudinal guide rail 325 mounted on the frame 3. The hook plate 322 has a hook hole, and the piston rod of the lower wire pressing cylinder 321 is connected to the hook hole. The wire feeding component 313 in the lower wire feeding assembly 32 is connected to a downwardly extending guide tube 324, and the wire feeding hole 316 on the wire feeding component 313 in the lower wire feeding assembly 32 is located on the guide tube 324. The upper wire feeding cylinder 311 drives the upper wire feeding assembly. Before component 31 is activated, the telescopic pressure rod 315 in the lower wire conveying component 32 extends and presses the prepared wire 7 in the guide tube 324. The lower wire conveying cylinder 321 drives the lower wire conveying component 32 to move downward so that the lower end of the guide tube 324 is aligned with the corresponding wire hole 91 on the brush plate 9. While guiding the wire into the wire hole, the guide tube 324 can restrict the wire that is passing through the wire inlet hole to stay inside the tube to prevent the wire that is passing through the wire inlet hole from spreading outward. At the same time, the lower wire conveying cylinder 321 can drive the wire conveying component 313 in the lower wire conveying component 32 to move downward so that the lower end of the prepared wire 7 is at the upper end of the wire hole 91, so as to prepare before the wire conveying mechanism 33 starts to convey wire.

[0058] Furthermore, such as Figure 3 As shown, the structure of the shredding mechanism 36 is as follows: The shredding mechanism 36 includes a fixed cutter 363 and a movable cutter 361 mounted on the frame 3 and horizontally opposite each other. A shredding cylinder 362 is connected to the movable cutter 361. When the prepared shreds 7 are pulled downward into place by the shredding mechanism 39, the shredding cylinder 362 drives the movable cutter 361 to approach the fixed cutter 363 to cut the prepared shreds 7.

[0059] Furthermore, the structure of the wire clamping mechanism 39 is as follows: The wire clamping mechanism 39 includes a wire clamping base 396 and a wire clamping assembly. The driving component is a wire clamping cylinder 395 connected to the lower end of the wire clamping base 396. The wire clamping assembly includes a first wire clamping member 391 and a second wire clamping member 392 disposed on the wire clamping base 396. At least one of the first wire clamping member 391 and the second wire clamping member 392 is connected to a clamping cylinder 393. The clamping cylinder 393 drives the first wire clamping member 391 and / or the second wire clamping member 392 to clamp the traction section 71. Then, the wire clamping cylinder 395 drives the wire clamping assembly to move downward to pull the prepared wire 7 downward into place.

[0060] Furthermore, such as Figure 9As shown, in this embodiment, one of the first wire clamping member 391 and the second wire clamping member 392 can be connected to a clamping drive member, or both the first wire clamping member 391 and the second wire clamping member can be connected to clamping drive members. In this way, when the corresponding clamping drive members work, they can drive the first wire clamping member 391 and the second wire clamping member 392 to clamp or loosen the traction section 71. In this embodiment, only one clamping drive member is used for explanation. Specifically, in this embodiment, the first wire clamping member 391 is a wire clamping block, and the second wire clamping member 392 is a wire clamping rod. The wire clamping block and the wire clamping rod are set on a wire clamping seat 396. The clamping drive member is a clamping cylinder 393 connected to the wire clamping block and driving the wire clamping block away from or close to the wire clamping rod. The wire clamping drive member is a wire clamping cylinder 395 set at the bottom of the wire clamping seat 396.

[0061] Furthermore, in order to prevent the traction section 71 from deforming under force and affecting the clamping effect when the clamping block and clamping rod clamp the traction section 71, the clamping block is provided with a clamping part for cooperating with the clamping rod and an extension part spaced apart from the clamping part. A strip-shaped groove 393 is formed between the extension part and the clamping part to accommodate the traction section 71 and extends longitudinally; so that the traction section 71 remains stable within the strip-shaped groove 393 when clamped by the clamping assembly.

[0062] Furthermore, the clamping rod and the extension are located on the same side. To avoid interference between the clamping rod and the extension, the extension is provided with a through groove that matches the clamping rod. The clamping rod is inserted into the through groove. When the piston rod of the clamping cylinder 393 extends, the clamping block moves away from the clamping rod, and the head of the clamping rod retracts into the through groove, so that the traction section 71 enters the strip groove 393. When the piston rod of the clamping cylinder 393 retracts, the clamping block approaches the clamping rod, and the head of the clamping rod enters the limiting groove to clamp the traction section 71 located in the strip groove 393. This design ensures that the clamping rod does not interfere with the extension while the clamping block is provided with the extension, and can cooperate normally with the clamping part.

[0063] Furthermore, after the cut wire 8 is inserted into 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. To fold the two strands outward, the frame 3 is provided with a wire folding mechanism 37. The wire folding mechanism 37 includes a wire folding frame 371 and a drive assembly for driving the wire folding frame 371 to move horizontally. The head of the wire folding frame 371 is the wire folding end, and the wire folding end has a strip groove 375 extending inward to the inside of the wire folding frame 371. The strip groove 375 divides the wire folding end into an upper wire folding part 375a and a lower wire folding part 375b. The wire folding frame 371 has a... The folding cavity extends vertically; the brush plate 9 is inserted into the strip groove 375, and the corresponding wire hole 91 on the brush plate 9 is located in the folding cavity; when the cut wire 8 is inserted into the wire hole 91, the cut wire 8 is divided into two strands of wire located on both sides of the brush plate 9. At this time, the wire clamping mechanism 39 releases the traction section 71, and the drive component drives the folding frame 371 to move away from the brush plate 9, so that the upper folding part 375a and the lower folding part 375b overlap the two strands of wire outward into a wire bundle; the folding mechanism 37 makes the two strands of wire quickly overlap into a wire bundle, improving the folding efficiency.

[0064] Furthermore, such as Figure 1 As shown, a guide assembly is provided inside the folding cavity. The guide assembly includes two opposing guide plates 372, one of which is connected to a guide cylinder 374. When the wire conveying mechanism 33 transports the prepared wire 7 downward, the piston rod of the guide cylinder 374 extends, causing the two guide plates 372 to come close together and form a guide groove 373 for guiding the prepared wire 7 into the wire hole 91. When the folding frame 371 moves away from the brush plate 9, the piston rod of the guide cylinder 374 retracts, causing the two guide plates 372 to move away from each other to avoid the outwardly overlapping stranded wires. In this embodiment, the guide assembly, while guiding the wire into the wire hole, also considers the problem of the guide plate avoiding the stranded wires during folding. Thus, the guide cylinder 374 controls the movement of one of the guide plates 372, effectively preventing the two stranded wires from interfering with the guide plate 372 when folding.

[0065] Furthermore, when the guide assembly is set in the wire folding cavity, the guide plate 372 is prone to interference with the brush plate 9. Therefore, in this embodiment, both guide plates 372 are provided with avoidance grooves (not shown) that correspond to the strip grooves 375 and are used to avoid the brush plate 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 plate inserted into the strip grooves 375, so that the wire folding work can proceed smoothly.

[0066] Furthermore, such as Figure 10As shown, to ensure that the brush disk 9 can rotate circumferentially along its own axis and to press and fix the filament bundle after folding, the brush disk 9 is mounted on a filament pressing assembly. Multiple filament holes 91 on the end face of the brush disk 9 form a mating area. The filament pressing assembly includes a support shaft 636 that can rotate circumferentially. The top of the support shaft 636 is provided with two filament pressing discs that mate with the upper and lower sides of the brush disk 9 and are located within the mating area. The outer periphery of the filament pressing discs and the outer periphery of the lower filament pressing disc 638 are evenly distributed with filament holes 91 corresponding to each other. A radial groove 631b is provided, and a radial pressure rod 633 is slidably connected within the radial groove 631b. Multiple radial guide grooves 632, connected by the radial grooves 631b, are evenly distributed circumferentially on the end face of the pressing disc facing away from the brush disc 9. The radial pressure rod 633 has a protrusion 634 extending beyond the end face of the pressing disc facing away from the brush disc 9 and slidably connected within the radial guide groove 632. The brush disc 9 divides the two pressing discs into an upper pressing disc 631 and a lower pressing disc 638. The frame 3 also has a section 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 the upper push-pull assembly 34; the lower push-pull rod 351 and the lower push-pull cylinder 353 constitute the lower push-pull assembly 35. The upper push-pull rod 341 is located inside the protrusion 634 of the upper pressure plate 631, and the lower push-pull rod 351 is located inside the lower pressure plate 638. The inner side of the protrusion 634; when the wire bending frame 371 overlaps the two strands of material into a 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 a direction away from the brush plate 9 and act on the corresponding protrusion 634, so that the corresponding radial pressure rod 633 extends and presses the two strands of material onto the corresponding end face of the brush plate 9; ensuring that the formed bundle of material remains fixed and does not spread outward, so as to fix the bundle of material.

[0067] Furthermore, such as Figure 7As shown, the structure of the wire folding mechanism 37 is as follows: The wire folding mechanism 37 is equipped with a linkage assembly, which includes a first support plate 374a and a second support plate 374b that are sequentially moved away from the wire folding frame 371. A first crossbar 377 is connected between the first support plate 374a and the second support plate 374b. The wire folding frame 371 is disposed on the first support plate 374a. The driving assembly includes a first driving cylinder 376 and a second driving cylinder 379 that act on the second support plate 374b. The piston rod of the first driving cylinder 376 extends and retracts, driving the wire folding frame 371 to move in a radial direction away from the brush plate 9, so as to make room for the radial pressure rod 633 to extend radially. When the radial pressure rod 633 extends and presses the stranded wire, the piston rod of the second driving cylinder 379 extends... The shrinking and folding mechanism drives the folding frame 371 to continue moving away from the brush plate 9, so that the folding frame 371 is completely separated from the filament bundle. The first driving cylinder 376 and the second driving cylinder 379 can drive the second support plate 374b in stages to compensate for the response time difference between the driving assembly and the upper push-pull cylinder 342 and the lower push-pull cylinder 353. When the piston rod of the first driving cylinder 376 extends and retracts to make room for the corresponding radial pressure rod 633, the two strands of filament are still stuck in the strip groove 375 and do not spread outward. After the radial pressure rod 633 presses the strands of filament, the extension and retraction of the piston rod of the second driving cylinder 376 completely disengages from the formed filament bundle, ensuring that after the folding mechanism 37 folds the filament, the corresponding movable pressure rod 633 can smoothly press the filament bundle.

[0068] Furthermore, since the wire hole 91 of the brush plate 9 is close to the outer peripheral edge of the brush plate 9, so that the two strands of wire can be folded together to form a wire bundle that extends beyond the outer periphery of the brush plate, and after the wire bundle is formed, the length of the strands of wire attached to the end face of the brush plate 9 is less than the length of the strands of wire extending beyond the brush plate 9. Therefore, to correspond to these two lengths, the extension and retraction stroke of the piston rod of the first drive cylinder 376 is less than the extension and retraction stroke of the piston rod of the second drive cylinder 379. Specifically, when the piston rod of the first drive cylinder 376 extends and retracts and drives the wire folding frame 371 to move in a radial direction away from the brush plate 9 and make 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 plate 9. Therefore, the range of motion of the wire folding frame 371 is short at this time. Afterwards, the wire folding frame 371 needs to completely detach from the wire bundle, which requires a longer range of motion. Therefore, the extension and retraction length of the piston rod of the second drive cylinder 379 is longer.

[0069] Furthermore, if the first drive cylinder 376 and the second drive cylinder 379 are arranged side by side to drive the wire bending frame 371 in steps, the extension and retraction of either the first drive cylinder 376 or the second drive cylinder 379 will inevitably drive the piston rod of the other cylinder, affecting the smoothness of the wire bending frame 371's movement. Therefore, to achieve the goal of driving the wire bending frame 371 in steps, the first drive cylinder 376 is mounted on the first support plate 374a, and the second drive cylinder 379 is mounted on the first longitudinal plate 378 near the first support plate 374a. The piston rods of the first drive cylinder 376 and the second drive cylinder 379 are opposite to each other and connected together. Specifically, a bushing is provided between the piston rods of the first drive cylinder 376 and the second drive cylinder 379. The piston rods of the first drive cylinder 376 and the second drive cylinder 379 are inserted into the bushing and locked with screws. This achieves the goal of driving the wire bending frame 374 in steps while saving space for the drive assembly.

[0070] Furthermore, such as Figure 15 As shown, at the outer periphery of the pressure plate, a limiting part 631a is formed between every two adjacent radial grooves 631b. The movable pressure rod 633 has two opposing side extensions 633a on both sides. When the movable pressure rod 633 retracts, the two side extensions 633a abut against the corresponding limiting part 631a to prevent the entire movable pressure rod 633a from being completely retracted into the radial groove 631b.

[0071] Furthermore, the bottom end of the movable pressure rod 633 has a limiting groove 635. After the movable pressure rod 633 extends, the stranded filaments are within the limitation of the limiting groove 635, preventing the stranded filaments from spreading to both sides.

[0072] Furthermore, multiple weight-reducing grooves 631c are provided on the end face of the pressing disc, which are continuous and evenly distributed along the circumference, so as to make the structure of the entire pressing disc 631 lighter.

[0073] Furthermore, such as Figure 2As shown, the specific structure of the upper push-pull assembly 34 is as follows: A horizontal plate 343 for mounting the upper push-pull assembly 34 is provided on the frame 3. The horizontal plate 343 has a clearance hole 344 for the guide tube 324. The upper push-pull assembly 34 includes a first vertical plate 346 mounted on the support frame 3. The upper driving component 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 component 341. To ensure smooth movement of the upper push-pull rod 341, the first vertical plate 346 has a mounting... The upper push-pull member 341 has a connecting plate 345. A second guide assembly is provided between the connecting plate 345 and the first vertical plate 346. The second guide assembly includes a second horizontal bar 344. The connecting plate 345 has a second guide hole that matches the second horizontal bar 344. The second guide holes are symmetrically arranged on the connecting plate 345. The number and position of the second horizontal bar 344 match the second guide hole. One end of the second horizontal bar 344 acts on the upper push-pull member 341, and the other end passes into the second guide hole, thereby guiding the upper push-pull member 341 to move.

[0074] Furthermore, such as 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 spaced apart on the support frame 3, and a third crossbar 355 is connected between the two mounting plates 352; the lower push-pull member 351 is mounted on the mounting plate 352 near the wire bending frame 371, and the second driving member is a lower push-pull cylinder 353 acting on the mounting plate 352 away from the wire bending frame 371; to ensure smooth movement of the lower push-pull rod 351, the support frame 3 is provided with a second vertical plate 354 for mounting the lower push-pull cylinder 353, and the second vertical plate 354 is provided with a third guide hole for sliding cooperation with the third crossbar 355; the third guide holes are symmetrically arranged on the second vertical plate 354, and the number and position of the third crossbar 355 match those of the third guide holes; this guides the lifting movement of the lower push-pull member 351.

[0075] Furthermore, the wire holes 91 on the brush plate 9 that are not yet threaded are classified as wire holes awaiting material, while the wire holes 91 containing wire bundles are classified as threaded holes; for example... Figure 11-13As shown, to ensure that the filament bundles at the threaded holes do not fork and deflect towards the waiting filament holes due to their own elasticity, the threading mechanism also includes a filament-pulling mechanism 38 mounted on the frame 3. The filament-pulling mechanism 38 is located on the side of the filament clamping seat 396 in the filament clamping mechanism 39. The filament-pulling mechanism 38 can move synchronously with the filament clamping mechanism 39 to approach or move away from the lower end of the brush plate 9. The filament-pulling mechanism 38 includes a movable lever 381 extending longitudinally and a rotating shaft 382. A filament-pulling drive is connected to the rotating shaft 382, ​​and the rotating shaft 382 is connected to the movable lever 381 through a linkage rod 383. The filament-pulling drive can drive the rotating shaft 382 to rotate and move the movable lever 381 to the adjacent threaded holes and waiting filament holes on the brush plate 9 to pull the filament bundles in the threaded holes to one side of the threaded holes. This allows the filament bundles in the next waiting filament hole to be threaded and folded smoothly, preventing the formed filament bundles from being rolled into the next formed filament bundles.

[0076] Furthermore, the specific structure of the wire-drawing mechanism 38 is as follows: the wire-drawing drive component can be directly connected to the rotating shaft 1 to drive the movable lever 381 to move, or the drive component can be indirectly connected to the rotating shaft 1 through a transmission assembly; in this embodiment, the rotating shaft 382 is set on a wire-drawing seat 386, and the wire-drawing seat 386 is provided with a transmission assembly, which includes a transmission rod 388 slidably connected to the wire-drawing seat 386, the transmission rod 388 is provided with multiple tooth grooves 389, and a swinging tooth 387 is fixedly connected to the shaft body of the rotating shaft 1, the swinging tooth 387 is provided with multiple teeth 387a that match the tooth grooves 389, and the drive component is a wire-drawing cylinder 384. The piston rod of the wire-drawing cylinder 384 is indirectly connected to the transmission rod 388 through a transition connecting plate 385. The extension and retraction of the piston rod of the wire-drawing cylinder 384 can drive the transmission rod 388 to slide on the wire-drawing seat 386, so that the tooth grooves 389 and the teeth 387a cooperate to drive the rotating shaft 1 to rotate.

[0077] Furthermore, compared to opening standard toothed grooves on the shaft of the transmission rod 388, the transmission rod 388 in this embodiment is lower in cost and easier to process. That is, the transmission rod 388 is a screw, and the toothed groove 389 is a helical groove set on the screw. Compared to opening standard toothed grooves on the transmission rod 388, directly using a screw with helical grooves is lower in cost, while also ensuring the meshing effect between the toothed groove 389 and the tooth 387a.

[0078] Furthermore, the size of the wire-drawing mechanism 38 needs to be miniaturized. A miniaturized wire-drawing mechanism 38 is easier to install into the corresponding position of the wire-threading mechanism. Therefore, in this embodiment, a receiving cavity 3861 is provided on the wire-drawing seat 386, and a mating part is provided on the rotating shaft 1 that passes through the receiving cavity 3861. The swing gear 387 is fixedly connected to the mating part. A sliding guide hole 3862 communicating with the outside is provided on the side wall of the receiving cavity 3861, and the transmission rod 388 is slidably connected in the sliding guide hole 3862. The receiving cavity 3861 can accommodate the transmission component in the wire-drawing seat 386, reducing the space it occupies in the wire-drawing mechanism, optimizing the structural layout of the wire-drawing mechanism, and facilitating the installation of the wire-drawing mechanism into the wire-threading mechanism for wire-drawing work.

[0079] 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 that is inserted into the sliding guide hole 3862; 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, so that the transmission rod 388 is connected to the transition connecting plate 385; a threaded rod is connected to the piston rod of the wire drawing cylinder 384; 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 engaged, they are locked by a nut, so that the piston rod is connected to the transition connecting plate 385.

[0080] Furthermore, when threading and folding wires one by one in multiple wire holes, it is only necessary to control the movable lever 381 to gather the wire bundles at adjacent threaded holes. However, when threading and folding wires in the last wire hole, the wire holes on both sides of the last wire hole have already been threaded and formed wire bundles. Therefore, another lever and the movable lever 381 are required for coordination. Figure 14 As shown, the wire-pulling mechanism 38 in this embodiment also includes a fixed lever 38a adjacent to the movable lever 381. When the support shaft 636 rotates and the last wire hole on the brush 9 is threaded, wire bundles are formed in the two wire-pulled holes adjacent to the wire hole. The wire-pulling drive drives the rotating shaft 382 to rotate, so that the movable lever 381 moves between one of the wire-pulled holes and the wire hole, and pulls the wire bundle on one side of one of the wire-pulled holes together. At this time, the fixed lever 38a is between the other wire-pulled hole and the wire hole, and pulls the wire bundle on the other side of the wire hole together.

[0081] The threading mechanism, in this embodiment, provides a threading method, including the following steps:

[0082] S1: The wire conveying mechanism 33 conveys the prepared wire 7 downwards, and the lower end of the prepared wire 7 passes through one of the wire holes 91 of the brush plate 9 to form a traction section 71 that extends beyond the lower end face of the brush plate 9.

[0083] S2: The wire clamping mechanism 39 clamps the traction section 71, and the drive member drives the wire clamping mechanism 39 to move downward, so as to pull the prepared wire 7 downward to the predetermined position.

[0084] S3: The shredding mechanism 36 cuts the prepared shreds 7, so that the cut shreds 8 of the predetermined length are inserted into the shred hole 91.

[0085] S4: Rotate the brush 9 and align the next wire hole 91 on the brush 9 with the prepared wire 7;

[0086] S5: Repeat steps S1-S4 in sequence until all wire holes 91 on the brush plate 9 are threaded. Through this threading method, each wire hole 91 on the brush plate 9 is threaded one by one, which improves the threading quality and efficiency and facilitates efficient threading of multiple brush plates 9 in batches on the threading mechanism.

[0087] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
