Description

Technical Field

[0001] This invention relates to the field of strip grinding, and in particular to a grinding brush disc forming device. 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 designed with multiple brush discs mounted on a roller shaft. Each brush disc includes a brush plate with multiple circumferentially distributed filament holes on its inner side. Resin filaments are threaded through these filament holes, forming two strands of filament at both ends of the brush plate. These two strands of filament are folded in half radially away from the brush plate to form a filament bundle. The filament bundle is then fixed to the two strands of filament by hot-melt welding to facilitate the polishing of the strip steel surface.

[0003] When forming this type of grinding brush, workers at different stations need to manually perform multiple forming processes sequentially. Workers need to thread the pre-determined length of filaments one by one through multiple filament holes on the brush, forming two strands of filaments. Then, the two strands of filaments at each filament hole are folded outward one by one to form multiple bundles of filaments protruding from the brush, completing the filament planting process of the brush. After the filament planting is completed, because the two strands of filaments folded outward are elastic, they are easy to spread outward. At this time, the two strands of filaments need to be pressed tightly onto the end face of the brush, and then the multiple bundles of filaments are fixed one by one using a hot melt welding machine. This manual operation is inefficient, and the labor and time costs are high when the grinding brush is produced on a large scale. Summary of the Invention

[0004] This invention provides a grinding brush disc forming device. By arranging a rotary mechanism for transferring brush discs between a seeding mechanism and a hot-melt welding mechanism, multiple brush discs without seeded wire are fed one by one onto the wire pressing assembly of the rotary mechanism. The brush discs without threaded wire are processed by seeding wire and wire bundle welding in sequence through the rotary mechanism to become grinding brush discs with grinding function. This improves the automation level of grinding brush disc processing, reduces the time and cost of manual processing of grinding brush discs, and improves the forming efficiency of grinding brush discs.

[0005] The technical solution of this invention is implemented as follows: A brush disc forming device, comprising: The machine base is a support component for the forming device. The machine base has material station 2, first processing station and second processing station arranged in sequence along the circumference. Material station 2 is used to place the brush plate without wire threading. Multiple wire holes are evenly distributed along the circumference on the end face of the brush plate. The multiple wire holes form a mating area on the end face of the brush plate. A rotary mechanism, located between material station 2, the first processing station, and the second processing station, includes a rotary table and a stepper drive. The rotary table is equipped with a wire pressing assembly, which includes an upper pressure plate and a lower pressure plate that rotate circumferentially along a vertical axis. The upper and lower pressure plates are respectively fitted into the mating areas on the upper and lower ends of the brush plate. Multiple radial pressure rods, each corresponding to a wire hole on the brush plate and capable of radial extension and retraction, are evenly distributed circumferentially on the outer periphery of both the upper and lower pressure plates. The stepper drive can drive the rotary table to rotate circumferentially along the vertical axis, allowing the brush plate to gradually switch between material station 2, the first processing station, and the second processing station. The seeding mechanism, located at the first processing station, includes a support frame with a threading mechanism and a cutting mechanism arranged longitudinally on the support frame. The threading mechanism can thread a preset length of filament into one of the filament holes of the brush plate, and the cutting mechanism can cut the threaded preset length of filament, dividing the preset length of filament into two strands located on the upper and lower sides of the brush plate. The seeding mechanism is also provided with a folding mechanism that forces the two strands of filament to overlap outward into a filament bundle. Above and below the folding mechanism are respectively provided an upper push-pull assembly and a lower push-pull assembly for acting on the radial pressure rod of the upper pressure plate and the radial pressure rod of the lower pressure plate to extend and press the two strands of filament. A hot melt welding mechanism, located at the second processing station, includes a hot melt welding machine with a welding head that can fix the wire bundle; After the brush plate is fed into the wire pressing assembly, the stepper drive drives the rotary table to rotate and moves the brush plate to the first processing station, where one of the wire holes on the brush plate is used for wire planting. Then, the upper and lower pressure plates rotate and align the next wire hole with the wire, alternating until all wire holes on the brush plate are planted. After the brush plate is planted, the stepper drive rotates the rotary table again, moving the brush plate to the second processing station, where one of the wire bundles on the brush plate is aligned with the welding head to complete the wire bundle welding. Then, the upper and lower pressure plates rotate at a predetermined angle and align the next wire bundle with the welding head, alternating until all wire bundles on the brush plate are welded and become the grinding brush plate.

[0006] Preferably, the brush plate and the upper pressure plate are also included. The brush plate and the upper pressure plate can be grasped and placed on the upper end of the lower pressure plate in sequence, or the upper pressure plate and the formed brush plate can be removed from the upper end of the lower pressure plate in sequence. The brush plate forming mechanism can replace manual labor and make the brush plate forming process more efficient.

[0007] Preferably, the rotary table has three mounting positions: a full mounting position corresponding to the first and second processing positions, and a half mounting position corresponding to material station 2. The full mounting position has an upper pressure plate and a lower pressure plate that align vertically; the half mounting position has a lower pressure plate. After the gripping mechanism picks up the brush and feeds it to the lower pressure plate, it picks up the upper pressure plate of the previous full mounting position and aligns it with the upper end of the lower pressure plate of the half mounting position, thus transforming the previous full mounting position into a half mounting position with only the lower pressure plate. Then, the rotary table rotates and aligns the lower pressure plate of the previous half mounting position with material station 2. This process is repeated to feed multiple brushes one by one to the various mounting positions on the rotary table, eliminating the need for manual placement of the brushes and improving feeding efficiency.

[0008] Preferably, after all the mounting positions on the rotary table have been filled with brushes, the previous mounting position adjacent to material station 2 only has a lower pressure plate and a pre-formed grinding brush mounted on the upper end of the lower pressure plate. Then the rotary table rotates and turns the pre-formed grinding brush back to align with material station 2. The pre-formed grinding brush is then removed by a gripping mechanism. This process is repeated to unload all the grinding brushes on the rotary table one by one, eliminating the need for manual removal of the grinding brushes and improving unloading efficiency.

[0009] Preferably, there is an empty waiting station between material station 2 and the second processing station. The rotary table has a full mounting position corresponding to the waiting station. When the brush plate is feeding or the grinding brush plate is unloading, the gripping mechanism grabs the upper pressure plate from the full mounting position corresponding to the waiting station and aligns it with the lower pressure plate in the half mounting position. The wire pressing assembly at the waiting station can increase the number of brush plates fed on the rotary table, and at the same time, it can prevent the gripping mechanism from moving to the full mounting position corresponding to the hot melt welding mechanism, thus avoiding interference between the gripping mechanism and the hot melt welding machine when gripping the upper pressure plate.

[0010] Preferably, the stepper drive is a first stepper motor located at the lower end of the rotary table. The first stepper motor drives the rotary table to rotate gradually, so that the brush disc passes through the first processing station and the second processing station in sequence from the material station 2 and becomes a grinding brush disc returning to the material station 2.

[0011] Preferably, the wire pressing assembly also includes a support shaft that can rotate along its own axis. The upper and lower pressure plates are located at the top of the support shaft and are circumferentially fixed to the support shaft. A second stepper motor is provided on the machine base at the corresponding position of the first and second processing stations. The second stepper motor is provided with an active seat, and the bottom of the support shaft is provided with a driven seat. The active seat and the driven seat form a clutch drive mechanism. When the seed wire or wire bundle welding is completed at one wire hole on the brush, the second stepper motor drives the active seat to link with the driven seat, so that the next wire hole on the brush rotates to a predetermined position and performs seed wire or wire bundle welding.

[0012] Preferably, the clutch drive mechanism is an electromagnetic clutch. When the electromagnetic clutch is energized, the driving seat and the driven seat form a magnetic coupling force.

[0013] Preferably, both the upper and lower pressure plates have a central hole, and a support shaft is concentrically mounted at the central hole. A control component for locking and unlocking the upper and lower pressure plates is located at the central hole. The control component includes a mating sleeve concentrically connected to the central hole of the upper pressure plate. The upper end of the support shaft has a receiving hole, and the inner wall of the receiving hole has a through-hole limiting hole. A movable limiting ball is located within the limiting hole. The mating sleeve has a limiting groove corresponding to the position of the limiting ball. The receiving groove contains... The device has a retractable movable shaft, which includes a large-diameter section and a small-diameter section. The large-diameter section of the movable shaft abuts against and engages a limiting ball in a limiting slot to keep the upper and lower pressure plates locked. The gripping mechanism includes a first gripping component and a retractable pressing component. When the gripping mechanism grips the upper pressure plate, the pressing component causes the movable shaft to retract elastically, so that the small-diameter section aligns with the position of the limiting ball. At this time, the limiting ball disengages from the limiting slot and unlocks the upper and lower pressure plates, so that the first gripping component can grip the upper pressure plate.

[0014] Preferably, the mating sleeve has a mating part that extends upward beyond the end face of the upper pressure plate, and the outer wall of the mating part is provided with a recessed annular slot. The first gripping assembly includes two opposing gripping cylinders, each gripping cylinder having a telescopic rod. When the pressing member actuates the movable shaft, the two telescopic rods extend and insert into the annular slot, forming a gripping force on the upper pressure plate.

[0015] Preferably, the material station 2 is equipped with an alignment mechanism, which includes an alignment drive and a rotating seat for supporting the brush discs. The brush discs have positioning holes, and the rotating seat has a detection element for detecting the positioning holes. The detection element and the alignment drive are both electrically connected to a controller. The alignment drive can drive the rotating seat and the brush discs to rotate. When the detection element detects the positioning holes, it sends a detection signal to the controller. The controller controls the alignment drive to stop rotating based on the detection signal, so that each brush disc is aligned to the predetermined position before feeding, thus avoiding misalignment between the first wire hole of the brush disc and the prepared wire when the brush disc is threading the wire. This ensures that each brush disc can be orderly adjusted to the predetermined position before feeding, guaranteeing the smooth processing of the seed wire.

[0016] Preferably, a through hole is provided in the middle of the rotary table, and a pushing mechanism independent of the rotary table is provided in the through hole. The pushing mechanism includes two telescopic push rods that are spaced apart vertically and are positioned opposite the upper and lower pressure plates on the mounting position of the hot melt welding mechanism. After all the wire bundles on the brush plate are welded and formed, the two telescopic push rods extend and retract, pushing the corresponding radial pressure rods on the upper pressure plate and the corresponding radial pressure rods on the lower pressure plate to retract and return to their original positions radially. Then, the stepper motor drives the brush plate on the wire pressing assembly to rotate gradually at a predetermined angle so that the next corresponding radial pressure rod is aligned with the corresponding telescopic push rod. This process is repeated alternately so that all the radial pressure rods on the upper pressure plate and all the radial pressure rods on the lower pressure plate retract and return to their original positions radially.

[0017] Preferably, the support frame is equipped with a wire feeding mechanism and a wire clamping mechanism located above and below the brush plate, respectively. The wire feeding mechanism 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. The wire clamping mechanism includes a wire clamping drive and a wire clamping assembly corresponding to the position of the traction section. After the wire clamping assembly clamps the traction section, the wire clamping drive drives the wire clamping assembly to move downward to pull the prepared wire into place. A wire cutting mechanism is provided between the brush plate and the wire feeding mechanism. After the wire clamping mechanism pulls the prepared wire into place, the wire cutting mechanism can cut the prepared wire so that the cut wire of a predetermined length is inserted into the wire hole.

[0018] Preferably, the support frame is equipped with a wire-folding mechanism corresponding to the brush plate. The wire-folding mechanism includes a wire-folding frame and a drive component for driving the wire-folding frame to move horizontally. 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 component 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, thereby improving the wire bundle forming efficiency.

[0019] Preferably, both the upper pressure plate and the lower pressure plate have multiple radial guide grooves evenly distributed circumferentially on their ends facing away from the brush plate. The radial pressure rod has a protrusion extending beyond the end face of the upper or lower pressure plate facing away from the brush plate and slidably connected within the radial guide groove. The upper push-pull assembly includes an upper push-pull rod and an upper push-pull cylinder, with the upper push-pull rod located inside the protrusion of the upper pressure plate. The lower push-pull assembly includes a lower push-pull rod and a lower push-pull cylinder, with the lower push-pull rod located inside the protrusion of the lower pressure plate. When the wire bending 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 a direction away from the brush plate and act on the corresponding protrusions, causing the corresponding radial pressure rod to extend and press the two strands of wire onto the corresponding end face of the brush plate. This keeps the two strands of wire fixed after they are overlapped into a wire bundle and prevents them from spreading outward, facilitating the next step of hot melt welding.

[0020] Preferably, the seed filament mechanism is equipped with a filament pulling mechanism, which includes a movable lever extending longitudinally and a rotating shaft. A filament pulling drive is connected to the rotating shaft, and the rotating shaft and the movable lever are connected by a linkage rod. When two strands of filament in one of the filament holes on the brush plate are combined into a filament bundle, the upper and lower pressure plates rotate and align the next filament hole on the brush plate with the prepared filament for re-threading. The filament pulling drive drives the rotating shaft to rotate and moves the movable lever to the space between the adjacent threaded and unthreaded filament holes on the brush plate, so as to pull the filament bundle at the threaded filament hole position along the circumferential direction of the brush plate. This prevents the filament bundle at the threaded filament hole from branching to the unthreaded filament hole side, ensuring that the filament bundle on the threaded filament hole side will not be entangled into the next filament bundle to be formed.

[0021] The beneficial effects of the present invention, which adopts the above technical solution, are as follows: The brush disc forming device of the present invention automates the brush disc processing process. By arranging a rotary mechanism for transferring brush discs between the seeding mechanism and the hot melt welding mechanism, multiple brush discs without seeding are fed one by one onto the wire pressing assembly of the rotary mechanism. The brush discs without threading are then processed by the rotary mechanism through seeding and wire bundle welding in sequence to become brush discs with grinding function. This reduces the time and cost of manual brush disc processing and improves the forming efficiency of brush discs.

[0022] The brush disc forming device of the present invention is equipped with a gripping mechanism. The gripping mechanism can grip an unthreaded brush disc for feeding, grip a formed brush disc for unloading, and grip the upper pressure plate on the rotary table, so as to switch between the mounting position and the semi-mounting position on the rotary table, and realize the cyclic feeding and unloading of brush discs. This design allows the wire pressing component on the rotary table to be recycled, saving the time of transferring materials at each station and maximizing the processing and forming efficiency of the brush disc.

[0023] In the seed silk mechanism, when threading the silk, the method of threading first, then pulling, and then cutting is adopted. The prepared silk is pulled into place in the silk hole of the brush plate in one go, and the silk cutting mechanism forms a cut silk of a predetermined length in the silk hole. The whole threading process is smooth and efficient, which improves the efficiency of threading silk in the silk hole.

[0024] After the wire threading is completed, the wire folding mechanism folds the stranded wires on both sides of the brush plate outward into a wire bundle. The upper and lower push-pull components act on the protrusions and drive the radial pressure rod to extend outward, thereby pressing the stranded wires tightly onto the end face of the brush plate. This prevents the stranded wires on the brush plate from spreading outward due to their own elasticity, ensuring the smooth progress of the next wire bundle welding process.

[0025] After the silk is seeded in the corresponding holes on the brush plate, a silk bundle will be formed at the threaded holes. The silk bundle itself is elastic, so it is easy to fork towards the side of the unthreaded holes. When the forked silk is folded in the next silk hole, it is easy to be rolled into the next silk bundle to be formed by the folding frame. Therefore, the silk pulling mechanism in this invention can drive the movable lever to move between the threaded and unthreaded silk holes through the silk pulling drive component, and pull the silk bundle on the side of the threaded hole together to ensure that the threading and folding processing can be carried out normally at the next silk hole, thus ensuring the quality of the seeded silk on the brush plate.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-30 As shown, the specific embodiments of the present invention are as follows: This embodiment provides a brush disc forming device, including: Machine base 1, which is a support component of the forming device; the machine base 1 has a material station 2, a first processing station and a second processing station arranged in sequence along the circumference. The material station 2 is used to place the brush plate 9 without threading; the brush plate 9 has a plurality of thread holes 91 evenly distributed along the circumference on its end face; the plurality of thread holes 91 form a mating area on the end face of the brush plate 9. A rotary mechanism 6 is located between the material station 2, the first processing station, and the second processing station. It includes a rotary table 62 and a stepper drive. The rotary table 62 is equipped with a wire pressing assembly 63, which includes an upper pressing plate 631 and a lower pressing plate 638 that rotate circumferentially along the vertical axis. The upper pressing plate 631 and the lower pressing plate 638 are used to engage with the mating areas on the upper end face and the lower end face of the brush plate 9, respectively. On the outer periphery of the upper pressing plate 631 and the outer periphery of the lower pressing plate 638, a plurality of radial pressing rods 633 are evenly distributed circumferentially, corresponding one-to-one with the wire holes 91 of the brush plate 9, and can extend and retract radially. The stepper drive can drive the rotary table 62 to rotate circumferentially along the vertical axis, so that the brush plate 9 can be gradually switched between the material station 2, the first processing station, and the second processing station. The seeding mechanism 3 is located at the first processing station. The seeding mechanism 3 includes a support frame 3a, on which a threading mechanism and a cutting mechanism 36 are arranged longitudinally. The threading mechanism can thread a preset length of filament into one of the filament holes 91 of the brush plate 9. The cutting mechanism 36 can cut the threaded preset length of filament, so that the preset length of filament is divided into two strands of filament located on the upper and lower sides of the brush plate 9. The seeding mechanism 3 is also provided with a folding mechanism that forces the two strands of filament to overlap outward into a filament bundle. Above and below the folding mechanism are respectively provided an upper push-pull assembly and a lower push-pull assembly for acting on the radial pressure rod 633 of the upper pressure plate 631 and the radial pressure rod 633 of the lower pressure plate 638 to extend and press the two strands of filament. The hot melt welding mechanism 4 is located at the second processing station and includes a hot melt welding machine with a welding head 41 that can fix the wire bundle. After the brush plate 9 is fed to the wire pressing assembly 63, the stepper drive drives the rotary table 62 to rotate and moves the brush plate 9 to the first processing station, where one of the wire holes 91 on the brush plate 9 is used for wire planting. Then, the upper pressure plate 631 and the lower pressure plate 638 rotate and align the next wire hole 91 with the wire, repeating this process until all wire holes 91 on the brush plate 9 are planted with wire. After the brush plate 9 has finished planting wire, the stepper drive rotates the rotary table 62 again, moving the brush plate 9 to the second processing station, where one of the wire bundles on the brush plate 9 is aligned with the welding head 41 to complete the wire bundle welding. Then, the upper pressure plate 631 and the lower pressure plate 638 rotate at a predetermined angle and align the next wire bundle with the welding head 41, repeating this process until all wire bundles on the brush plate 9 are welded and become the grinding brush plate.

[0030] Furthermore, such as Figure 1-2 As shown, the brush disc forming device also includes a gripping mechanism 5. The gripping mechanism 5 can sequentially grip and place the brush disc 9 and the upper pressure plate 631 onto the upper end of the lower pressure plate 638, and can also sequentially remove the upper pressure plate 631 and the formed brush disc from the upper end of the lower pressure plate 638. The gripping mechanism 5 can replace manual labor, making the brush disc forming process more efficient. Specifically, the gripping mechanism 5 has a disc gripping mode and a material gripping mode. In the disc gripping mode, the gripping mechanism 5 can grip the previous fully installed position adjacent to the semi-installed position. The upper pressure plate 631 is then aligned with the upper end of the lower pressure plate 638 in the semi-installation position; in the material gripping mode, the gripping mechanism 5 can grip the brush plate 9 without wire threading from the material table 2 and place it in the semi-installation position, or it can remove the brush plate with wire threading from the semi-installation position; the gripping mechanism 5 includes a movable robotic arm, and a gripping plate is installed at the outer end of the robotic arm. The gripping plate is provided with multiple magnetic chucks 51 evenly distributed in the circumferential direction. The magnetic chucks 51 can use magnetic force to pick up the brush plate 9, thereby realizing the feeding of the brush plate 9 and the unloading of the brush plate.

[0031] Furthermore, such as Figure 20-21As shown, to improve the feeding efficiency of the brushes 9, the rotary table 62 has three mounting positions. The mounting positions are divided into full mounting positions corresponding to the first processing station and the second processing station, and half mounting positions corresponding to the material station 2. The full mounting position has an upper pressure plate 631 and a lower pressure plate 638 that are aligned vertically; the half mounting position has a lower pressure plate 638. The gripping mechanism 5 first switches to the material gripping mode. After gripping the brushes 9 and feeding them to the lower pressure plate 638, the gripping mechanism 5 switches to the disc gripping mode and grips the upper pressure plate 631 of the previous full mounting position and aligns it with the upper end of the lower pressure plate 638 of the half mounting position, thus transforming the previous full mounting position into a half mounting position with only the lower pressure plate 638. Then the rotary table 62 rotates and aligns the lower pressure plate 638 of the previous half mounting position with the material station 2. This cycle repeats, feeding multiple brushes 9 one by one to the various mounting positions on the rotary table 62, eliminating the need for manual placement of the brushes 9 and improving feeding efficiency.

[0032] Furthermore, such as Figure 22-23 As shown, the gripping mechanism 5, in conjunction with the rotary mechanism 6, can also improve the feeding efficiency of the grinding brush discs. After all the brush discs 9 are loaded onto all the mounting positions on the rotary table 62, the previous mounting position adjacent to the material station 2 only has the lower pressure plate 638 and the already formed grinding brush disc mounted on the upper end of the lower pressure plate 638. Then, the rotary table 62 rotates and turns the formed grinding brush disc back to align with the material station 2. The gripping mechanism 5 then removes the formed grinding brush disc. This process is repeated to feed all the grinding brush discs onto the rotary table 62 one by one, eliminating the need for manual removal of the grinding brush discs and improving feeding efficiency.

[0033] Furthermore, when the gripping mechanism 5 is in the disc gripping mode, it can directly grip the upper pressure plate 631 on the mounting position corresponding to the hot melt welding mechanism 4 and align the upper pressure plate 631 with the lower pressure plate 638 on the half mounting position corresponding to the material table 2. However, the gripping mechanism 5 is prone to interference with the hot melt welding mechanism 4 when it moves. Therefore, in this embodiment, there is also an empty waiting station between the material station 2 and the second processing station. The rotary table 62 has a full mounting position corresponding to the waiting station. When the brush plate 9 is loading or the grinding brush plate is unloading, the gripping mechanism 5 grips the upper pressure plate 631 from the full mounting position corresponding to the waiting station and aligns it with the lower pressure plate 638 on the half mounting position. The wire pressing assembly at the waiting station can increase the number of brush plates 9 loaded on the rotary table 62, and at the same time, the gripping mechanism 5 does not need to move to the full mounting position corresponding to the hot melt welding mechanism 4, thus avoiding interference between the gripping mechanism 5 and the hot melt welding machine when gripping the upper pressure plate 631.

[0034] Furthermore, although the aforementioned cyclic feeding and unloading methods can improve the processing efficiency of the brush discs 9, the gripping mechanism 5 needs to remove the formed brush discs after feeding multiple brush discs 9 to their corresponding mounting positions. This removal process takes time. Therefore, to further improve the processing efficiency of the brush discs 9, in this embodiment, in addition to cyclic feeding and unloading, simultaneous feeding and unloading can also be performed. After all the mounting positions on the rotary table 62 have been filled with brush discs 9, the gripping mechanism 5 removes a pre-formed brush disc from a half-mounting position while simultaneously placing an un-filamented brush disc 9 onto the same half-mounting position. Then, the upper pressure plate 631 of the previous full-mounting position is gripped and aligned with the upper end of the lower pressure plate 638 of the half-mounting position, transforming the previous full-mounting position into a half-mounting position containing only the lower pressure plate 638 and the brush disc mounted on top of it. The rotary table 62 then rotates, causing the brush disc in the previous half-mounting position to return to the position corresponding to the material station 2. This alternating process completes the process of loading the brush discs 9. The brush plates are loaded and unloaded synchronously. Depending on the processing requirements, the operator can freely choose between the cyclic loading and unloading mode and the synchronous loading and unloading mode. When there are many brush plates 9 without wire thread on the material table 2, the operator can choose synchronous loading and unloading, so that the gripping mechanism 5 can remove the formed brush plate from the semi-installation position and load a brush plate 9 without wire thread onto the semi-installation position at the same time, thereby improving the forming efficiency of the brush plate. However, when there are few brush plates 9 without wire thread on the material table 2 or when the operator needs to unload all the formed brush plates, the operator can choose synchronous loading and unloading to avoid leaving any formed brush plates on the rotary table 62.

[0035] Furthermore, such as Figure 3 As shown, the stepper drive is the first stepper motor 61 located at the lower end of the rotary table 62. The first stepper motor 61 drives the rotary table 62 to rotate gradually, so that the brush 9 passes through the first processing station and the second processing station from the material station 2 and becomes the brush returning to the material station 2.

[0036] Furthermore, to ensure that the next wire hole 91 on the brush plate aligns with the seed wire mechanism or the hot melt welding machine when the upper pressure plate 631 and the lower pressure plate 638 rotate gradually, the wire pressing assembly 63 also includes a support shaft 636 that can rotate along its own axis. The upper pressure plate 631 and the lower pressure plate 638 are located at the top of the support shaft 636 and are circumferentially fixed to the support shaft 636. A second stepper motor 64 is provided on the machine base 1 at the corresponding positions of the first processing station and the second processing station. The brush 9 is equipped with an active seat 641 and a driven seat 637 at the bottom of the support shaft 636. The active seat 641 and the driven seat 637 form a clutch drive mechanism. The clutch drive mechanism is an electromagnetic clutch. When the seed wire or wire bundle welding is completed at one wire hole 91 on the brush 9, the electromagnetic clutch is energized. The second stepper motor 64 drives the active seat 641 to form a magnetic linkage force on the driven seat 637, so that the next wire hole 91 of the brush 9 rotates to the predetermined position and performs seed wire or wire bundle welding.

[0037] Furthermore, such as Figure 24 As shown, the upper pressure plate 631 and the lower pressure plate 638 need to remain stable after engagement. When the gripping mechanism 5 grips the upper pressure plate 631, the upper pressure plate 631 and the lower pressure plate 638 need to separate. Therefore, to meet this requirement, both the upper pressure plate 631 and the lower pressure plate 638 are provided with a central hole. A support shaft 636 is concentrically installed at the central hole position, and a control component for locking and unlocking the upper pressure plate 631 and the lower pressure plate 638 is provided at the central hole position. The control component includes a mating sleeve 66 concentrically connected to the central hole 63a position of the upper pressure plate 631. The upper end of the support shaft 636 is provided with a receiving hole, and a through limiting hole 636a is provided on the inner wall of the receiving hole. A movable limiting ball 68 is provided in the limiting hole 636a, and the mating sleeve 66 is provided with a limiting ball corresponding to the position of the limiting ball 68. The accommodating groove 662 contains a retractable movable shaft 67. A compression spring 661 is located at the lower end of the movable shaft 67, providing elastic force for its extension and retraction. The movable shaft 67 includes a large-diameter section 672 and a small-diameter section 671. The large-diameter section 672 abuts against and engages a limiting ball 68 within the limiting groove 662, thus locking the upper pressure plate 631 and the lower pressure plate 638. The gripping mechanism 5 includes a first gripping component and a retractable pressing member 52. When the gripping mechanism 5 grips the upper pressure plate 631, the pressing member 52 causes the movable shaft 67 to extend and retract elastically, aligning the small-diameter section 671 with the limiting ball 68. At this time, the limiting ball 68 disengages from the limiting groove 662, unlocking the upper pressure plate 631 and the lower pressure plate 638, allowing the first gripping component to grip the upper pressure plate 631.

[0038] Furthermore, the first gripping assembly grips the upper pressure plate 631 in the following way: the mating sleeve 66 has a mating part that extends upward beyond the end face of the upper pressure plate 631, and the outer wall of the mating part is provided with a recessed annular slot 663. The first gripping assembly includes two opposing gripping cylinders, and the gripping cylinders have telescopic insert rods 53. When the pressing member 52 actuates the movable shaft 67, the two telescopic insert rods 53 extend and insert into the annular slot 663 and form a gripping force on the upper pressure plate 631.

[0039] Furthermore, such as Figure 6 As shown, to ensure that the first wire hole 91 on the brush 9 is aligned with the wire when the gripping mechanism 5 grips the brush 9 to feed the wire and thread it, an alignment mechanism is provided on the material station 2. The alignment mechanism includes an alignment drive 24 and a rotating seat 21 for supporting the brush 9. The alignment drive 24 is a servo motor, which is installed in a U-shaped support. The brush 92 has a positioning hole 92, and the rotating seat 21 has a detection element for detecting the positioning hole 92. The detection element and the alignment drive are also included. Each of the 24 components is electrically connected to a controller. The alignment drive 24 can drive the rotating seat and brush 9 to rotate. When the detection element detects the positioning hole 92, the detection element sends a detection signal to the controller. The controller controls the alignment drive 24 to stop rotating according to the detection signal, so that each brush 9 is aligned to the predetermined position before feeding, so as to avoid the first wire hole 91 of the brush 9 being misaligned with the prepared wire 7 when the brush 9 is threading the wire. This ensures that each brush 9 can be orderly adjusted to the predetermined position before feeding, and ensures that the seed wire processing is carried out smoothly.

[0040] Furthermore, the detection element is an infrared sensor 25; the infrared sensor 25 is low in cost and highly sensitive, and can accurately detect the positioning hole 92 on the end face of the brush disk 9; specifically, the infrared sensor 25 always emits a detection beam that illuminates the end face of the brush disk 9. When the rotating seat 21 drives the brush disk 9 to rotate until the positioning hole 92 corresponds to the detection beam, the detection beam can send a signal to the controller that the detection is in place, so that the controller controls the drive to stop working, so that the brush disk 9 stops at the predetermined position.

[0041] Furthermore, the rotating seat 21 is provided with a positioning platform 22 that protrudes upward and matches the inner hole of the brush plate 9; the positioning platform 22 can facilitate the setting and positioning of the brush plate 9 and prevent the brush plate 9 from moving laterally on the rotating seat 21.

[0042] Furthermore, in order to enable the brush plate 9 to be placed quickly and accurately on the rotating seat, the upper surface of the positioning platform 22 is provided with multiple guide cones 23 near the outer periphery. The guide cones 23 are tapered structures that are narrower at the top and wider at the bottom. When the brush plate 9 is fitted, they can guide the brush plate 9. Even if there is a slight error in the position between the inner hole of the brush plate 9 and the positioning platform 22, the guide cones 23 can guide the brush plate 9 into place through the tapered surface, thereby quickly completing the installation and positioning.

[0043] Furthermore, such as Figure 3 As shown, after the wire bundle welding is completed, the radial pressure rods 633 of the upper pressure plate 631 and the lower pressure plate 638 are both in the extended state. If they are not reset, it will be difficult to press the stranded wires again when the wire pressing assembly 63 rotates back with the rotary table 62 to correspond with the seed wire mechanism 3. Therefore, in this embodiment, a through hole is provided in the middle of the rotary table 62, and a pushing mechanism 65 independent of the rotary table 62 is provided in the through hole. The pushing mechanism 65 includes two telescopic mechanisms that are spaced apart vertically and are sequentially opposite to the positions of the upper pressure plate 631 and the lower pressure plate 638 on the mounting position of the hot melt welding mechanism 4. Push rod 652; After all the wire bundles on the brush plate 9 are welded and formed, the two telescopic push rods 652 extend and retract and push against the corresponding radial pressure rods 633 on the upper pressure plate 631 and the corresponding radial pressure rods 633 on the lower pressure plate 638 to return to their original positions radially. Then, the second stepper motor 64 drives the brush plate 9 on the wire pressing assembly 63 to rotate gradually at a predetermined angle so that the next corresponding radial pressure rod 633 is aligned with the corresponding telescopic push rod 652. This process is repeated alternately so that all the radial pressure rods 633 on the upper pressure plate 631 and all the radial pressure rods 633 on the lower pressure plate 638 return to their original positions radially.

[0044] Furthermore, such as Figure 8-14 , Figure 18 As shown, when the seed silk mechanism 3 is threading the silk, in order to ensure threading efficiency, it does not adopt the method of cutting first and then threading the silk. Specifically, the support frame 3a is provided with a silk conveying mechanism 33 and a silk clamping mechanism 39 located above and below the brush plate 9, respectively. The silk conveying mechanism 33 can transport the prepared silk 7 from top to bottom, and after the prepared silk 7 passes through one of the silk holes 91 of the brush plate 9, it forms a traction section 71 that extends beyond the lower end face of the brush plate 9. The silk clamping mechanism 39 includes a silk clamping drive and a silk clamping assembly corresponding to the position of the traction section 71. After the silk clamping assembly clamps the traction section 71, the silk clamping drive drives the silk clamping assembly to move downward to pull the prepared silk 7 downward into place. A silk cutting mechanism 36 is provided between the brush plate 9 and the silk conveying mechanism 33. After the silk clamping mechanism 39 pulls the prepared silk 7 downward into place, the silk cutting mechanism 36 can cut the prepared silk 7, so that the cut silk 8 of a predetermined length is threaded into place in the silk hole 91.

[0045] Furthermore, the support frame 3a 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 support frame 3a, the wire conveying assembly including a wire conveying component 313, the wire conveying component 313 is provided with a wire inlet hole 316 that passes through from top to bottom and is used to accommodate 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 inlet hole, the wire conveying component 313 is connected to a clamping cylinder 314, the clamping cylinder 314 has a telescopic pressure rod 315 that is inserted into the wire inlet hole 316 and used to clamp or release 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 support frame 3a, the upper wire conveying assembly 31 is connected to an upper wire conveying cylinder 311, and the wire conveying component 31 in the upper wire conveying assembly 31... A wire guide rod 312 is connected to the upper part of the support frame 3a. The top of the support frame 3a is provided with a support plate for installing the upper wire guide cylinder 311. The wire guide rod 312 is slidably connected in the guide hole provided in the support plate. 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 plate 9 forms the traction section 71. The wire guide mechanism 33 can stably transport the prepared wire 7 downward in an alternating transport mode to ensure that the lower end face of the brush plate 9 forms the traction section 71.

[0046] Furthermore, the lower wire feeding assembly 32 is driven by a lower wire feeding cylinder 321 and moves longitudinally. Specifically, the support frame 3a is provided with a hook plate 322 for easy connection. The hook plate 322 is mounted on a sliding plate 323, which is slidably connected to a longitudinal guide rail 325 mounted on the support frame 3a. The hook plate 322 has a hook hole, and the piston rod of the lower wire feeding 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 inlet 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... Before the upper wire conveying assembly 31 is activated, the telescopic pressure rod 315 in the lower wire conveying assembly 32 extends and presses the prepared wire 7 in the guide tube 324. The lower wire conveying cylinder 321 drives the lower wire conveying assembly 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 assembly 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.

[0047] Furthermore, the structure of the shredding mechanism 36 is as follows: The shredding mechanism 36 includes a fixed cutter 363 and a movable cutter 361, which are mounted on the support frame 3a and are 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.

[0048] 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.

[0049] Furthermore, 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 provided 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 disposed 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 disposed at the bottom end of the wire clamping seat 396.

[0050] 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 is formed between the extension part and the clamping part to accommodate the traction section 71 and extend longitudinally; so that the traction section 71 remains stable in the strip-shaped groove when clamped by the clamping assembly.

[0051] 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. 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 in the strip groove. 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.

[0052] Furthermore, such as Figure 15 , Figure 19 , Figure 25 As shown, after the cut wire 8 enters the wire hole 91, wire bending processing is required. Therefore, the support frame 3a is equipped with a wire bending mechanism corresponding to the brush plate 9. The wire bending mechanism includes a wire bending frame 371 and a drive assembly for driving the wire bending frame 371 to move horizontally. The head of the wire bending frame 371 is the wire bending end, and the wire bending end has a strip groove 375 extending into the inside of the wire bending frame 371. The strip groove 375 divides the wire bending end into an upper wire bending part 375a and a lower wire bending part 375b. The wire bending frame 371 has a through-wire running vertically through it. The brush plate 9 is inserted into the strip groove 375, and the corresponding wire hole 91 on the brush plate 9 is 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; thereby improving the forming efficiency of the wire bundle.

[0053] Furthermore, the upper push-pull assembly 34 and the lower push-pull assembly 35 extend the radial pressure rod 633 as follows: Multiple radial guide grooves 632, connected by radial sliding grooves 631b, are evenly distributed circumferentially on the end face of the upper pressure plate 631 facing away from the brush plate 9 and the end face of the lower pressure plate 638 facing away from the brush plate 9. The radial pressure rod 633 has a protrusion 634 extending beyond the end face of the upper pressure plate 631 or the end face of the lower pressure plate 638 facing away from the brush plate 9 and slidably connected within the radial guide groove 632. The upper push-pull assembly includes an upper push-pull rod 341 and an upper push-pull cylinder 342. The upper push-pull rod 341 is located within the protrusion 634 of the upper pressure plate 631. Inside, the lower push-pull assembly includes a lower push-pull rod 351 and a lower push-pull cylinder 353. The lower push-pull rod 351 is located inside the protrusion 634 of the lower pressure plate 638. When the wire bending frame 371 overlaps the two strands of wire outward into a wire bundle, the upper push-pull cylinder 342 and the lower push-pull cylinder 353 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 wire onto the corresponding end face of the brush plate 9. This keeps the two strands of wire fixed after they are overlapped into a wire bundle and prevents them from spreading outward, which is convenient for the next step of hot melt welding.

[0054] Furthermore, such as Figure 8-9 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.

[0055] 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 groove 375 and are used to avoid the brush plate 9. The avoidance groove divides the entire guide plate 372 into two guide support plates. The avoidance groove can prevent the guide plate 372 from interfering with the brush plate inserted into the strip groove 375, so that the wire folding can proceed smoothly.

[0056] Furthermore, such as Figure 25As 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 379 completely disengages from the formed filament bundle, ensuring that after the folding mechanism 37 folds the filament, the corresponding radial pressure rod 633 can smoothly press the filament bundle.

[0057] Furthermore, since the wire hole 91 of the brush plate 9 is close to the outer peripheral edge of the brush plate 9, it is convenient for the two strands of wire to be folded together to form a wire bundle that extends beyond the outer periphery of the brush plate. 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 driving cylinder 376 is less than the extension and retraction stroke of the piston rod of the second driving cylinder 379. Specifically, when the piston rod of the first driving 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 radial 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 driving cylinder 379 is longer.

[0058] 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.

[0059] Furthermore, such as Figure 16-17 As shown, at the outer periphery of the pressure plate, a limiting part 631a is formed between every two adjacent radial grooves 631b. The radial pressure rod 633 has two opposing side extensions 633a on both sides. When the radial pressure rod 633 retracts, the two side extensions 633a abut against the corresponding limiting part 631a to prevent the entire radial pressure rod 633a from being completely retracted into the radial groove 631b.

[0060] Furthermore, the bottom end of the radial pressure rod 633 has a limiting groove 635. After the radial 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.

[0061] Furthermore, multiple weight-reducing grooves 631c are provided on the end face of the pressure plate, which are evenly distributed along the circumference, so as to make the structure of the entire pressure plate 631 lighter.

[0062] Furthermore, such as Figure 7 As shown, in order to prevent the brush plate 9 from moving circumferentially on the wire pressing assembly, the lower pressing plate 638 has a positioning protrusion 631d on its end face facing the upper pressing plate 631, and the brush plate 9 has a positioning notch 93 on its end face that matches the positioning protrusion 631d. The positioning protrusion 631d is stuck in the positioning notch 93.

[0063] Furthermore, in order to prevent the upper pressure plate 631 and the lower pressure plate 638 from moving relative to each other in the circumferential direction, the end face of the upper pressure plate 631 facing the lower pressure plate 638 is provided with a pin hole corresponding to the position of the positioning protrusion 631d, and the positioning protrusion 631d is inserted into the pin hole.

[0064] Furthermore, 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... The upper part is provided with a connecting plate 345 for mounting the upper push-pull member 341. A second guide assembly is provided between the connecting plate 345 and the first vertical plate 346. The second guide assembly includes a second crossbar. The connecting plate 345 is provided with a second guide hole that matches the second crossbar. The second guide holes are symmetrically arranged on the connecting plate 345. The number and position of the second crossbar match the second guide hole. One end of the second crossbar 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.

[0065] Furthermore, such as Figure 26 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.

[0066] Furthermore, the unthreaded wire holes 91 on the brush plate 9 are classified as wire-waiting holes, and the wire holes 91 with wire bundles are classified as wire-threaded holes. After the wire is seeded in the corresponding wire holes 91 on the brush plate 9, a wire bundle will be formed at the wire-threaded hole 91. The wire bundle itself is elastic, so it is easy to fork towards the unthreaded wire hole 91. When the forked wire is bent in the next wire hole 91, it is easy to be wound into the next wire bundle to be formed by the bending frame 371. Therefore, the seeding mechanism 3 in this embodiment is provided with a wire-pulling mechanism 38, such as... Figure 27-30As shown, the wire drawing mechanism 38 includes a movable lever 381 extending longitudinally and a rotating shaft 382. A wire drawing 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. When two strands of material wire in one of the wire holes 91 on the brush plate 9 are combined into a wire bundle, the upper pressure plate 631 and the lower pressure plate 638 rotate and align the next wire hole 91 of the brush plate 9 with the prepared material wire 7 for re-threading, the wire drawing drive drives the rotating shaft 382 to rotate, and the movable lever 381 moves to the space between the adjacent threaded wire hole 91 and the unthreaded wire hole 91 on the brush plate 9, so as to gather the wire bundle at the position of the threaded wire hole 91 along the circumferential direction of the brush plate 9; so that the wire bundle at the threaded wire hole will not fork to the side of the unthreaded wire hole, and ensure that the wire bundle on the side of the threaded wire hole will not be rolled into the next wire bundle to be formed.

[0067] Furthermore, the specific structure of the wire drawing mechanism 38 is as follows: the wire drawing drive can be directly connected to the rotating shaft 382 to drive the movable lever 381 to move, or the drive can be indirectly connected to the rotating shaft 382 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 382, ​​the swinging tooth 387 is provided with multiple teeth 387a that match the tooth grooves 389, the drive 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 382 to rotate.

[0068] 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, it is lower in cost to directly use a screw with helical grooves, while also ensuring the meshing effect between the toothed groove 389 and the tooth 387a.

[0069] Furthermore, the size of the wire-drawing mechanism 38 needs to be miniaturized. A miniaturized wire-drawing mechanism 38 is easier to install. Therefore, in this embodiment, a receiving cavity 3861 is provided on the wire-drawing seat 386. The rotating shaft 382 has a mating part that passes through the receiving cavity 3861. The swing gear 387 is fixedly connected to the mating part. The side wall of the receiving cavity 3861 is provided with a sliding guide hole 3862 that communicates with the outside. 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 making it easier for the wire-drawing mechanism to be installed in the corresponding position for wire-drawing work.

[0070] 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.

[0071] Furthermore, when threading and folding multiple wire holes one by one, it is only necessary to control the movable lever 381 to gather the wire bundles at the adjacent threaded holes. However, when threading and folding the last wire hole, the wire holes on both sides of the last wire hole have been threaded and formed wire bundles. Therefore, another lever and the movable lever 381 are required to cooperate. 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 plate 9 is threaded, wire bundles are formed in the two threaded holes adjacent to the wire hole. The wire pulling drive drives the rotating shaft 382 to rotate, so that the movable lever 381 moves to between one of the threaded holes and the wire hole and gathers the wire bundle on one side of the threaded hole. At this time, the fixed lever 38a is between the other threaded hole and the wire hole and gathers the wire bundle on the other side of the threaded hole.

[0072] Furthermore, during welding, because the fixed wire bundle is composed of multiple separate elastic wires, the welding head 41 exerts a compressive force on the wire bundle when it descends. This can easily cause the multiple wires to spread out to the sides or bend upwards, resulting in an unreliable weld. Figure 4-5As shown, the hot melt welding mechanism 4 in this invention includes a welding auxiliary mechanism that cooperates with the welding head 41. The welding auxiliary mechanism includes an auxiliary power component and a positioning component. The positioning component includes a pressure plate 424 and a positioning rod 421a arranged sequentially from top to bottom. The top end of the positioning rod 421a has two opposing side stops 421b, and a constraint groove 421c is formed between the two side stops 421b for accommodating the wire bundle and corresponding to the position of the welding head 41. The auxiliary power component includes components for driving the positioning rod 421a and the pressure plate 424 respectively. A first driving member 421 and a second driving member 423 move longitudinally; the first driving member 421 drives the positioning rod 421a to move upward to approach the wire bundle, and the second driving member 423 drives the pressure plate 424 to move downward to press the wire bundle into the constraint groove 421c, so that the wire bundle remains stable in the constraint groove 421c when welding with the welding head 41; after welding is completed, the first driving member 421 drives the positioning rod 421a to move downward, and the second driving member 423 drives the pressure plate 424 to move upward, so that the wire bundle comes out of the constraint groove 421c.

[0073] Furthermore, the installation layout of the positioning component and the power component is as follows: The welding auxiliary mechanism also includes a base, and the first driving component 421 is a first cylinder mounted on the base. The first cylinder has a first piston rod that extends and retracts longitudinally and is connected to the positioning rod 421a. The first cylinder extends and retracts sensitively and rapidly, driving the positioning rod 421a to extend and retract quickly. To avoid interference with the first cylinder, a horizontal plate 426, which is spaced apart from the base, is installed on the cylinder body of the first cylinder. The second driving component 423 is mounted on the horizontal plate 426 and connected to the first cylinder. A second cylinder is staggered and has a second piston rod that extends and retracts longitudinally. An extension plate 424a is mounted on the second piston rod and is connected to a pressure plate 424 so that the position of the pressure plate 424 corresponds to the top position of the positioning rod 421a. During wire bundle welding, the pressure plate 424 needs to be close to the constraint groove 421c to press the wire bundle. The extension plate 424a can compensate for the distance between the second cylinder and the first cylinder due to the spatial layout, so that the position of the pressure plate 424 corresponds to the constraint groove 421c, thereby stably pressing the wire bundle.

[0074] Furthermore, in order to stably compress the wire bundle when the welding head 41 is working, the pressure plate 424 will press the upper surface of the wire bundle. However, completely pressing the upper surface of the wire bundle will cause the welding head 41 to interfere with the pressure plate 424. Therefore, in this embodiment, the pressure plate 424 is provided with a relief opening 425 corresponding to the position of the constraint groove 421c and used to avoid the welding head. The relief opening 425 provides welding relief space to avoid interference between the welding head 41 and the pressure plate 424, so that the welding head 41 can pass through the relief opening 425 to weld the wire bundle.

[0075] Furthermore, to ensure smooth up-and-down movement of the positioning rod 421a, a first guide assembly is installed on the horizontal plate 426. The horizontal plate 426 serves as the mounting carrier for the second cylinder and also as the mounting carrier for the first guide assembly. The first guide assembly includes two support rods symmetrically arranged on the horizontal plate 426. The top ends of the two support rods are connected to a first guide plate 422. The first guide plate 422 has a guide groove corresponding to the position of the positioning rod 421a. The positioning rod 421a moves longitudinally within the guide groove, allowing the welding auxiliary mechanism to switch between the working state and the reset state. The guide groove on the first guide plate 422 provides guidance for the positioning rod 421a. This ensures that when the welding auxiliary mechanism is in the working state, the upper end of the positioning rod 421a extends beyond the upper end of the first guide plate 422. When the welding auxiliary mechanism is in the reset state, the upper end of the positioning rod 421a retracts downward into the guide groove, without affecting the movement of the next wire bundle on the brush to the corresponding welding position.

[0076] Furthermore, in order to ensure that the pressure plate 424 moves up and down without deviation, a second guide assembly is installed on the cylinder body of the second cylinder. The second guide assembly includes a second guide plate 424c installed on the cylinder body of the second cylinder. The second guide plate 424c has symmetrically opened guide holes. A second guide rod 424b connected to the extension plate 424a is slidably connected in the guide holes. The second guide rod 424b cooperates with the guide holes to provide movement guidance for the pressure plate 424 and the extension plate 424a.

[0077] 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 spirit of the present invention, such designs should fall within the protection scope of the present invention.

The upper push-pull assembly includes an upper push-pull rod (341) and an upper push-pull cylinder (342). The upper push-pull rod (341) is located on the protrusion (634) of the upper pressure plate (631). Inside 34), the lower push-pull assembly includes a lower push-pull rod (351) and a lower push-pull cylinder (353). The lower push-pull rod (351) is located inside the protrusion (634) of the lower pressure plate (638). When the wire folding frame (371) overlaps the two strands of material into a bundle, the upper push-pull cylinder (342) and the lower push-pull cylinder (353) 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).

15. The brush disc forming device according to claim 1, characterized in that: The seed silk mechanism (3) is provided with a silk pulling mechanism (38). The silk pulling mechanism (38) includes a movable lever (381) extending longitudinally and a rotating shaft (382). A silk pulling drive is connected to the rotating shaft (382), and the rotating shaft (382) and the movable lever (381) are connected by a linkage rod (383). When two strands of material silk in one of the silk holes (91) on the brush plate (9) are stacked into a silk bundle, the upper pressure plate (631) and the lower pressure plate (638) rotate and align the next silk hole (91) of the brush plate (9) with the prepared material silk (7) for re-threading, the silk pulling drive drives the rotating shaft (382) to rotate and moves the movable lever (381) to the space between the adjacent threaded silk hole (91) and the unthreaded silk hole (91) on the brush plate (9) to gather the silk bundle at the position of the threaded silk hole (91) along the circumferential direction of the brush plate (9).
