Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent manufacturing, and in particular to an automated device for producing double-row hole twisted wire brushes. Background Technology
[0002] Twisted wire brushes are industrial cleaning tools commonly used for metal surface treatment, with functions such as rust removal, deburring, and weld cleaning. To improve cleaning efficiency and extend service life, twisted wire brush structures, in which steel wires are fixed to the brush plate in a twisted bundle, have been increasingly adopted in industrial production in recent years. Traditional twisted wire brushes are mostly single-row structures, with a ring of mounting holes on the outer edge of the brush plate, through which bundles of steel wires are inserted and twisted.
[0003] With increasing industrial demand for high-strength, high-density brush filament arrangements, the twisted-filament brush structure with double-row holes has begun to be widely used. (Reference) Figure 1 In this structure, the brush disc has two concentric rings of mounting holes, forming inner and outer rows of bristles to improve the grinding capacity per unit area. However, in automated production, existing single-row hole production equipment cannot produce double-row hole structures. Because the inner and outer row mounting holes are located at different radial positions, using single-row hole production equipment results in uneven torque transmission due to differences in distance from the center of the brush disc when performing the same twisting operation at different row positions. Specifically, the same torque applied to the inner row of steel wire bundles results in a stronger tension due to the shorter lever arm; while applied to the outer row of steel wire bundles, the actual tension is weaker due to the longer lever arm, leading to problems such as inconsistent bristle tension and structural instability.
[0004] Currently, there is a lack of effective automation solutions to address this uneven stress problem. Existing equipment is mostly an extension of single-row structures and does not fully consider the mechanical adaptation and control compensation under double-row structures. Summary of the Invention
[0005] The purpose of this invention is to provide an automated device for producing double-row twisted wire brushes. Addressing the issue of torque transmission differences caused by inconsistent radial positions of the double-row brush filaments, this invention achieves precise alignment and fitting of the inner and outer rows of holes in the twisted wire brush by incorporating a laterally movable twisting mechanism linked to the feeding path. This effectively solves the technical problems of inconsistent filament tension and structural instability caused by the inability of existing single-row equipment to match lever arm changes in a double-row environment.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:
[0007] An automated device for producing double-row hole twisted wire brushes includes a frame and a component mounted on the frame:
[0008] The chip assembly includes an intermittently rotating workstation, with the brush disk of the twisted wire brush mounted on the workstation.
[0009] The wire twisting mechanism includes a wire twisting bracket and a twisting head. The twisting head has a groove that can be adapted to the outer ring of the wire twisting brush. The inner wall of the groove has a through hole that is coaxially connected to the mounting hole of the brush disk. The frame is provided with a wire twisting transverse movement mechanism that can drive the wire twisting bracket to reciprocate along the radial direction of the brush disk. The twisting head is rotatably connected to the wire twisting bracket. The wire twisting bracket is provided with a rotating device for driving the twisting head to rotate about the linear direction of the wire twisting transverse movement mechanism as the axis. The wire twisting mechanism also includes a pin inserted into the twisting head and a pin pushing mechanism suitable for driving the pin to slide along the axial direction of the twisting head.
[0010] The feeding mechanism is suitable for conveying the twisted wire bundle to the work station, so that the twisted wire bundle passes through the mounting hole of the brush plate and the through hole of the twisting head.

The transmission assembly includes a first pulley on the output shaft of the rotating device, a second pulley on the twisting head, and a synchronous belt connecting the first pulley and the second pulley; wherein the diameter of the second pulley is larger than the diameter of the first pulley.
[0014] Further configuration: The hook wire mechanism includes a first hook wire support and a hook wire lifting mechanism mounted on the first hook wire support, with the hook wire mounted on the output shaft of the hook wire lifting mechanism; it also includes a second hook wire support and a hook wire lateral movement mechanism mounted on the second hook wire support, the hook wire lateral movement mechanism driving the first hook wire support to move laterally, thereby enabling the hook wire to move laterally while being lifted.
[0015] Further configuration: The shredding mechanism includes:
[0016] A first cutter post and a second cutter post, wherein the output end of the shredding traverse mechanism is drivenly connected to the second cutter post, and the shredding lifting mechanism is disposed on the second cutter post and its output end is drivenly connected to the first cutter post; and
[0017] A vertical blade and a rotary blade are mounted on the first tool holder, and a driver is provided to drive the rotary blade to rotate.
[0018] Further configuration: A transmission structure is provided between the output shaft of the driver and the rotating blade, the transmission structure including a first gear on the output shaft of the driver and a second gear on the rotating blade; the diameter of the second gear is smaller than the diameter of the first gear.
[0019] Further configuration: The feeding mechanism includes:
[0020] The first feeding rack, on which the first feeding rack is equipped with the first wheel set;
[0021] The second feeding rack is equipped with a second set of wheels.
[0022] The feeding frame reciprocating mechanism drives the second feeding frame to reciprocate relative to the first feeding frame, so that the first wheel set and the second wheel set clamp the twisted wire bundle;
[0023] A power source outputs rotational motion, which is applied to the first or second wheel set to clamp and feed the twisted wire bundle; and
[0024] The feeding rack lateral movement mechanism acts on the first feeding rack so as to drive the second feeding rack to move laterally as well.
[0025] Further configuration: Both the first wheel set and the second wheel set are equipped with clamps to form clamping channels for holding the twisted wire bundle.
[0026] Further configuration: The first wheel set includes a driving wheel and at least one driven wheel, the driving wheel and the driven wheel are connected by a conveyor belt, and the clamp is disposed on the conveyor belt for moving with the conveyor belt to clamp and transport the twisted wire bundle.
[0027] Further configuration: The chip mechanism also includes a workstation support, the workstation is rotatably connected to the workstation support, and the workstation support is provided with a drive device that drives the workstation to rotate.
[0028] In summary, the present invention has the following beneficial effects:
[0029] First, in this invention, by setting a twisting wire transverse movement mechanism that can reciprocate along the radial direction of the brush disk, and a twisting head with a perforated and slotted structure, the twisting wire mechanism can complete the processing of single-row hole twisted wire brushes under a single equipment structure, and after lateral offset, it can adapt to the position of double-row holes on the outer ring of the brush disk, realize the continuous twisting operation of inner and outer row holes, and greatly improve the production efficiency and consistency of double-row twisted wire brushes.
[0030] Furthermore, the twisting support, feeding mechanism, and filament cutting mechanism are all equipped with laterally movable structures to adapt to twisting brush structures with different diameters, ensuring consistent twisting quality. Each mechanism can move outwards or inwards to the appropriate position when processing the inner and outer rows of holes, keeping the twisting path always coaxially aligned with the brush plate holes. This ensures consistency in the force path, tension angle, and torque transmission during the rotational twisting process. Compared to traditional fixed-path structures, this solution can dynamically adjust the working position to meet the uniform twisting requirements under different lever arm conditions of the double rows, resulting in more stable filament formation and significantly improved structural consistency.
[0031] Secondly, in this invention, the torque compensation design improves the symmetry of brush bristle tension and extends service life. The equipment's structural design fully considers the distance difference between the twisting head and the brush plate holes. Through the cooperation of the twisting bracket and the rotating device, the twisting head rotates around the axis of the lateral movement, enabling stable twisting action at each hole position. The pusher mechanism slides along the axis of the twisting head, allowing the twisted bristle bundle to obtain axial positioning and support before twisting, effectively preventing swaying, misalignment, or deflection during high-speed rotation. During the twisting process, even with changes in the inner and outer row lever arms, the axial stability of torque transmission and the balanced release of torque can still be achieved, thereby reducing the loosening and fatigue failure of the outer row brush bristles due to insufficient force, and improving the durability and uniformity of the brush bristles.
[0032] Third, the feeding mechanism, shredding mechanism and twisting mechanism of the present invention all have lateral movement capability, and can adjust their positions synchronously after the brush plate rotates, so as to achieve precise alignment when switching from the inner row hole processing position to the outer row hole processing position. At the same time, through the second cutting position setting of the shredding lateral movement mechanism, the length of the brush filament bundle is automatically adjusted when switching between rows, so as to ensure that the brush filament shape is consistent under the double row structure.
[0033] Fourth, in the transmission assembly, the diameter of the first pulley on the output shaft of the rotating device is smaller than the diameter of the second pulley on the twisting head. According to the basic principles of gear or belt drives, when the diameter of the driving pulley is smaller than that of the driven pulley, a speed reduction and torque increase effect is achieved. This means that the relatively high rotational speed output by the rotating device, after passing through this transmission assembly, will be converted into a lower rotational speed and a greater torque at the twisting head. Through this speed reduction and torque increase pulley transmission, the strong and stable torque required for the twisting head can be obtained even with standard or more compact rotating devices, ensuring that each twisted filament bundle achieves ideal tension and forming quality, thereby solving the problems of inconsistent filament tension and structural instability. This speed reduction and torque increase design can effectively reduce the workload and load on the driving rotating device, thereby reducing its wear, extending its service life, and potentially reducing operating energy consumption.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings.
[0054] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0055] An automated device for producing double-row hole twisted wire brushes, specifically designed for production. Figure 1 In this embodiment, the twisted wire bundle 30 in the double-row hole twisted wire brush is a steel wire bundle.
[0056] like Figure 2 As shown, it includes a frame 100, a chip mechanism 500 disposed on the frame 100, a wire twisting mechanism 600, a feeding mechanism 300, a wire cutting mechanism 200, and a wire hooking mechanism 400.
[0057] Among them, such as Figure 2 and Figure 3 As shown, the chip mechanism 500 is located at the center of the frame 100, including an intermittently rotating station 502. The brush 10 can be installed on the station 502 and, under the action of the drive device 503, the station 502 is intermittently rotated, thereby driving the brush 10 to rotate sequentially and align with different processing positions.
[0058] The chip mechanism 500 also includes a workstation bracket 501. The workstation 502 is rotatably connected to the workstation bracket 501. The output end of the drive device 503 is connected to the workstation 502, which can drive the workstation 502 to rotate intermittently around its axis, so as to realize the accurate switching of the brush disk 10 between the positions of each mounting hole 20, so that the brush disk 10 can complete the alignment operation of each mounting hole 20 in sequence, and cooperate with the wire twisting mechanism 600 to realize the continuous twisting operation of multiple rows and multiple bundles of steel wires.
[0059] like Figure 4 , Figure 5 and Figure 6 As shown, the wire twisting mechanism 600 is located on the outer periphery of the chip mechanism 500. It includes a twisting head 602 mounted on a wire twisting bracket 601. The twisting head 602 has a slot 608 that matches the outer ring of the brush plate 10. The inner wall of the slot 608 has a through hole 609 for coaxial alignment with the mounting hole 20 of the brush plate 10, so that the wire bundle can be inserted. The twisting head 602 is rotatably connected to the wire twisting bracket 601, and the wire twisting bracket 601 is driven by a wire twisting transverse movement mechanism 607 mounted on the frame 100, and can reciprocate along the radial direction of the brush plate 10, thereby adapting to the different radial positions of the inner and outer mounting holes 20 of the brush plate 10. The wire twisting bracket 601 is also provided with a rotating device 605 for driving the twisting head 602 to rotate around the wire twisting transverse movement direction as the axis, thereby realizing the twisting and forming of the wire bundle. The twisting mechanism 600 is also equipped with a pin 603, which passes through the hollow cavity of the twisting head 602 and cooperates with the pin pushing mechanism 604 to realize the sliding movement of the pin 603 along the axis of the twisting head 602. This is used to press and position the end of the wire bundle before twisting to ensure that the twisting process is stable.
[0060] like Figure 7 and Figure 8 As shown, the feeding mechanism 300 is located on one side of the twisting mechanism 600, and is suitable for sequentially conveying bundled steel wires to the current working position of the chip mechanism 500, so that the steel wire bundle passes through the mounting hole 20 of the brush plate 10 and the through hole 609 of the twisting head 602, forming a preliminary positioning. The feeding path and the position of the twisting mechanism 600 cooperate to form a through feeding channel, ensuring that the steel wire bundle is accurately fed into each hole.
[0061] like Figure 9 and Figure 10 As shown, the shredding mechanism 200 is located on the feeding path, downstream of the feeding mechanism 300 and upstream of the twisting mechanism 600. It includes a shredding lateral movement mechanism 208 and a shredding lifting mechanism 207 to realize horizontal displacement and positioning and vertical lifting and cutting actions. The shredding mechanism 200 has two cutting positions, which correspond to the shredding length matching requirements of the inner and outer holes, respectively.
[0062] like Figure 11As shown, the hook wire mechanism 400 is arranged on the side of the twisting wire mechanism 600 near the chip mechanism 500, including the hook wire 401 body and its support structure. The hook wire 401 can move vertically under the action of the lifting mechanism, and at the same time move horizontally through the transverse mechanism. It is used to guide or pre-deform the steel wire bundle before twisting, and to provide space and angle assistance for subsequent twisting.
[0063] Through the coordination of structural layout, action rhythm and control system, the above-mentioned mechanisms realize precise feeding, fixed-length wire cutting, top pressure positioning, synchronous wire twisting and stable forming of double-row hole twisting brush at different radial positions.
[0064] Furthermore, such as Figure 4 , Figure 5 As shown, the twisting mechanism 600 also includes a transmission assembly 610 disposed between the rotating device 605 and the twisting head 602, for transmitting rotational driving force and amplifying torque. The transmission assembly 610 includes a first pulley 611 disposed on the output shaft of the rotating device 605, a second pulley 612 disposed on the twisting head 602, and a synchronous belt 613 connecting the first pulley 611 and the second pulley 612.
[0065] The first pulley 611 is coaxially fixed to the output shaft of the rotating device 605 and is used to receive the power signal output by the rotating device 605. The second pulley 612 is coaxially connected to the toggle head 602, allowing the toggle head 602 to rotate at high speed along its own axis under the drive of the second pulley 612. A synchronous belt 613 is arranged around the first pulley 611 and the second pulley 612 for synchronous power transmission. Preferably, the diameter of the second pulley 612 is larger than the diameter of the first pulley 611. By utilizing the transmission ratio relationship of the pulleys with unequal diameters, a transmission effect of reduced speed and amplified torque is achieved at the output end, thereby enhancing the twisting ability of the toggle head 602 on the wire bundle and ensuring sufficient twisting strength and structural tightness during the brush filament forming process. This is particularly suitable for situations with high wire distribution density and large twisting load in double-row hole structures.
[0066] Through the above configuration, the transmission component 610 can not only achieve efficient power coupling between the rotating device 605 and the twisting head 602, but also utilize the speed and torque differences formed by pulleys of different diameters to achieve mechanical optimization of the brush filament twisting process, further improving the versatility and forming stability of the equipment under the double-row structure.
[0067] In a further optimized embodiment of the present invention, such as Figure 11 As shown, the hook wire mechanism 400 includes a first hook wire support 402 and a second hook wire support 403. The first hook wire support 402 is provided with a hook wire lifting mechanism 405. The hook wire 401 is installed on the output shaft of the hook wire lifting mechanism 405 and is used to perform lifting and lowering movements in the vertical direction (i.e., the vertical direction).
[0068] The second hook wire support 403 is located at the bottom or side of the hook wire mechanism 400, and is used to support and install the hook wire lateral movement mechanism 404. The output end of the hook wire lateral movement mechanism 404 is connected to the first hook wire support 402, thereby driving the first hook wire support 402 to move laterally relative to the second support in the horizontal direction. Through this structural design, the hook wire 401 can simultaneously or sequentially perform horizontal movement operations under the drive of the lateral movement mechanism while completing the vertical lifting and lowering action.
[0069] Therefore, after insertion, hook wire 401 can move laterally under the drive of the lateral movement mechanism, squeezing or deflecting the inserted wire bundle to form a preset interlaced or deformed structure. This helps to stabilize the subsequent twisting process and improves the consistency and tightness of the brush wire bundle twisting. It is particularly suitable for interference elimination and structural forming control under dense double-row brush wire arrangement. The above structure, through the cooperation of the split bracket and the linkage mechanism, realizes compound movement in the spatial direction, ensuring the accuracy and flexible adaptability of the hook wire 401's guiding action.
[0070] In a further improvement of the present invention, such as Figure 9 and Figure 10 As shown, the slicing mechanism 200 includes a first blade holder 201 and a second blade holder 202. The second blade holder 202 is located at the output end of the slicing transverse movement mechanism 208 and can reciprocate horizontally under its drive. The first blade holder 201 is located above the second blade holder 202. The slicing lifting mechanism 207 is mounted on the second blade holder 202 and is connected to the first blade holder 201 via its output end. It is used to drive the first blade holder 201 to move vertically up and down to achieve the cutting operation of the steel wire bundle.
[0071] The first cutter holder 201 is equipped with a slicing assembly, including a vertical blade 203 and a rotating blade 204, which are arranged opposite each other to form a shearing structure. The rotating blade 204 is driven to rotate by a driver 209 mounted on the second cutter holder 202. To achieve power transmission between the driver 209 and the rotating blade 204, a transmission structure is provided between the output shaft of the driver 209 and the rotating blade 204. The transmission structure includes a first gear 205 mounted on the output shaft of the driver 209 and a second gear 206 coaxially connected to the rotating blade 204.
[0072] Preferably, the diameter of the second gear 206 is smaller than that of the first gear 205, thereby forming a certain speed ratio relationship through the gear transmission structure, thereby increasing the rotational speed of the rotating blade 204, completing high-speed shearing within a unit time, improving the wire cutting efficiency, and ensuring neat cuts and smooth cross-sections, avoiding problems such as wire scattering or burrs caused by insufficient speed.
[0073] With the above-mentioned structural configuration, the shredding mechanism 200 can complete the fixed-length cutting operation at any fixed point on the feeding path. Combined with the shredding lateral movement and lifting action, it can not only adapt to the double-row hole arrangement with different row spacing, but also automatically adjust the cutting position according to the brush filament length, thereby improving the adaptability of the equipment and the precision control of the production cycle.
[0074] like Figure 7 and Figure 8 As shown, in a further optimized embodiment of the present invention, the feeding mechanism 300 includes a first feeding frame 301 and a second feeding frame 302. The first feeding frame 301 and the second feeding frame 302 are arranged opposite to each other on both sides of the feeding path, and are used to clamp and convey the twisted wire bundle 30. The first feeding frame 301 is provided with a first wheel set 303, and the second feeding frame 302 is provided with a second wheel set 305. The first wheel set 303 and the second wheel set 305 cooperate to form a clamping area.
[0075] It also includes a feeding frame reciprocating mechanism 309, which drives the second feeding frame 302 to reciprocate horizontally relative to the first feeding frame 301. This enables clamping or loosening between the first wheel set 303 and the second wheel set 305 during the early stage of feeding, allowing the twisted wire bundle 30 to move controllably between the wheel sets. To achieve continuous feeding of the wire bundle, the feeding mechanism 300 also includes a power source 308, which outputs rotational motion and acts on the first wheel set 303 or the second wheel set 305 to drive the wheel set to rotate and clamp the wire bundle for linear feeding.
[0076] Furthermore, to accommodate the array of mounting holes 20 with different row spacings on the brush plate 10, the feeding frame lateral movement mechanism 307 is set on one side of the first feeding frame 301, with its output end connected to the first feeding frame 301. It can drive the first feeding frame 301 and the second feeding frame 302 to move laterally along the radial direction of the brush plate 10, thereby shifting the feeding path as a whole, realizing the rapid switching between the inner row hole and the outer row hole positions, and improving the flexibility and automation of feeding positioning.
[0077] To further improve clamping stability, both the first wheel group 303 and the second wheel group 305 are equipped with clamps 306 for constraining the position of the wire bundle. The clamps 306 work in conjunction with the rotation of the wheel group to provide a stable clamping channel during the wire bundle conveying process, effectively preventing the wire bundle from slipping or shifting.
[0078] Preferably, the first wheel group 303 includes one driving wheel and at least one driven wheel. The driving wheel is connected to the driven wheel via a conveyor belt 304, forming a closed conveying loop. The clamp 306 is fixedly disposed on the outside of the conveyor belt 304, so that it moves synchronously under the drive of the conveyor belt 304, thereby continuously clamping and conveying the wire bundle during the clamping process, ensuring feeding accuracy and improving feeding cycle time. It is particularly suitable for the precise positioning and stable feeding of wire bundles of different lengths under a double-row hole arrangement. The above-mentioned feeding mechanism 300 achieves coordinated linkage of clamping, feeding and lateral movement in its structure, with strong adaptability, stable operation, good scalability and automated production efficiency.
[0079] like Figure 3 As shown, in this embodiment, the chip mechanism 500 also includes a loading mechanism 510 and a unloading mechanism 520. The loading mechanism 510 is disposed on one side of the frame 100 and is suitable for accurately installing the brush plate 10 to be processed onto the workstation 502, completing the positioning and fixing operation of the brush plate 10. The specific structure of the loading mechanism 510 is not limited, and various forms such as a robotic arm, push rod device, or pneumatic clamp 306 can be adopted according to actual needs to ensure that the brush plate 10 can be stably and efficiently assembled onto the workstation 502.
[0080] Meanwhile, the unloading mechanism 520 is located on the opposite side or below the workstation 502, and is used to push the finished twisted wire brush out of the workstation 502 after the twisting process is completed, so as to realize the automatic unloading of the finished product. The specific structure of the unloading mechanism 520 is not limited, and it can adopt a cylinder push rod, a sliding plate mechanism or a robotic arm gripping method to match the intermittent movement of the workstation 502 and the cycle requirements of finished product conveying.
[0081] The aforementioned feeding mechanism 510 and unloading mechanism 520 are respectively set to correspond to the workstation 502 of the chip mechanism 500. Through reasonable spatial layout and synchronous control, the automatic loading and unloading of the twisted wire brush before and after processing is realized, thereby improving the automation level and production efficiency of the whole machine.

[0083] In this embodiment, the driver 209, power source 308, drive device 503, and rotating device 605 are preferably all driven by servo motors. Specifically, the driver 209 is used to drive the rotating blade 204 in the slicing mechanism 200 to rotate, so as to achieve fixed-length cutting of the twisted wire bundle 30; the power source 308 is used to provide a continuous and stable rotational force to the first wheel group 303 or the second wheel group 305 in the feeding mechanism 300, so as to achieve clamping and conveying of the twisted wire bundle 30; the drive device 503 is mounted on the station bracket 501 of the chip mechanism 500, and is used to drive the station 502 to achieve intermittent self-rotation, so as to align with each mounting hole 20 on the brush plate 10 in sequence; the rotating device 605 is mounted on the twisted wire bracket 601, and drives the twisting head 602 to rotate at high speed around the twisted wire transverse direction as the axis by outputting rotational power, thereby achieving effective twisting of the wire bundle. The aforementioned driving components, through the precise control of servo motors, improve the response speed and synchronization accuracy of each action process, ensuring the consistency of the cycle time and the consistency of the finished product throughout the entire twisted wire brush processing flow.
[0084] The present invention also provides a method for producing a double-row hole twisted wire brush, comprising the following steps:
[0085] First, the initialization step of station 502 is performed, which involves installing the twisted brush disk 10 to be processed onto station 502 of the chip mechanism 500. Station 502 is rotatably connected to station bracket 501 and is driven by drive device 503 set on station bracket 501 to achieve intermittent self-rotation. After each twisting cycle of the brush filament bundle is completed, station 502 rotates by an equidistant angle, thereby sequentially aligning with the multiple mounting holes 20 on the brush disk 10, ensuring that each hole enters the processing stage in sequence.
[0086] Next, the feeding and positioning step is carried out. After the feeding mechanism 300 is started, the steel wire bundle is clamped by the first wheel group 303 and the second wheel group 305 set on the first feeding frame 301 and the second feeding frame 302, and fed into the current hole to be processed. The steel wire bundle passes through the mounting hole 20 on the brush plate 10 and the through hole 609 set coaxially with it in the inner wall of the groove 608 of the twist head 602 to achieve precise positioning.
[0087] Then, the shredding and length setting step begins. The shredding mechanism 200 is activated, and the shredding lifting mechanism 207 installed on the second blade holder 202 is brought above the feeding path by the shredding lateral movement mechanism 208 on the frame 100. This drives the first blade holder 201 to move up and down in the vertical direction, thereby driving the vertical blade 203 and the rotating blade 204 on the first blade holder 201 to cooperate in cutting the twisted wire bundle 30 at the feeding position, completing the length setting.
[0088] After the wire pretreatment is completed, the wire twisting process is performed. During this process, the wire twisting transverse movement mechanism 607 drives the wire twisting bracket 601 to move along the radial direction of the brush plate 10 to the corresponding mounting hole 20 position. The front end of the twisting head 602 is aligned with the annular groove 608 provided on the edge of the brush plate 10. After insertion and positioning, the ejector pin 603 inside the twisting head 602 is pushed out along the axial direction under the drive of the ejector pin pushing mechanism 604, pressing against the end of the wire bundle to achieve stable end fixation. Subsequently, the rotating device 605 is started, and the transmission component 610 provided in the wire twisting bracket 601 drives the twisting head 602 to rotate at high speed around its axis, realizing the twisting and knotting of the wire bundle, thereby forming a solid single bundle brush filament structure.
[0089] After completing the processing of a row of holes (such as an inner row of holes), the cycle time switching and row-to-row conversion steps are executed. At this time, the station 502 in the chip mechanism 500 rotates, driving the brush disk 10 to rotate to the processing position 502 corresponding to the outer row of holes. To match the different radial positions of the outer row of holes, the lateral movement structure of the feeding mechanism 300 and the wire twisting mechanism 600 is activated, so that the feeding path and the wire twisting position are laterally offset by a set distance to accurately align with the outer row of holes. At the same time, the lateral movement device of the wire cutting mechanism 200 also moves accordingly and adjusts the cutting length to adapt to the wire bundle length required for the new hole position, ensuring the consistency of the processing of the inner and outer row of steel wire bundles.
[0090] The subsequent hook wire 401 guiding step is executed, in which the hook wire mechanism 400 is activated, and the hook wire 401, which is mounted on the hook wire lifting mechanism 405, rises vertically and inserts into the side of the twisted wire bundle 30 that has passed through the mounting hole 20 of the brush plate 10. The lateral movement mechanism then drives the hook wire 401 to move laterally in the horizontal direction, so that the wire bundle is pre-tensioned or deflected to provide space and angle assistance for subsequent twisting.
[0091] Finally, the cycle synchronization step begins, where the control system repeats the feeding, filament cutting, twisting, and guiding processes described above. The chip mechanism 500 drives the workstation 502 to rotate sequentially to the next hole to be processed. Simultaneously, the feeding mechanism 300, filament cutting mechanism 200, filament hooking mechanism 400, and filament twisting mechanism 600 reset in sequence, preparing for the next processing cycle. This method continues in a loop until all the twisted filament bundles 30 in the inner and outer rows of holes on the brush plate 10 are processed, thus achieving efficient and automated manufacturing of the double-row hole twisted filament brush.
