Description

Technical Field

[0001] This invention relates to the field of shield tail brush production technology, and in particular to a shield tail brush thread rolling machine. Background Technology

[0002] With the rapid development of rail transit, the application of tunnel boring machines (TBMs) required for rail transit construction is becoming more and more widespread, and the demand for tail brushes is also surging. The quality of the tail brush bristles is also a major concern for customers, such as the straightness, pattern, and length of the bristles.

[0003] Chinese patent CN201820093535.1 discloses a wire feeding and rolling mechanism for a shield tail brush rolling mill. The mechanism includes a rolling mill with a knitting gear set, a knitting reverse gear set, and a rubber roller set sequentially arranged on one side. The knitting reverse gear set is connected to a knitting reverse transmission gear via a transmission shaft. The rubber roller set is connected to a rubber roller set transmission gear via a transmission shaft. The knitting reverse transmission gear and the rubber roller set transmission gear are connected to a drive gear via a chain. The drive gear is connected to a motor. The rolling mill is equipped with a motor speed regulator. The diameter of the rubber roller set transmission gear is smaller than that of the knitting reverse transmission gear, while the diameter of the rubber rollers in the rubber roller set is larger than that of the knitting reverse gear in the knitting reverse gear set. The knitting reverse gear set and the rubber roller set drive the brush filaments to move through meshing force and friction, and the brush filaments drive the knitting positive gear set to rotate. This improves production efficiency, reduces scrap rate, increases part lifespan, and saves costs.

[0004] However, this technical solution primarily focuses on the mechanical optimization of the wire feeding and rolling processes, and its functionality remains relatively limited. It lacks effective means for efficient and automated processing and quality control of the rolled brush filaments, particularly addressing issues such as bending, tangling, and uneven distribution of the filaments after rolling and cutting. The straightness and uniformity of the brush filaments, as key indicators directly affecting the sealing performance of the tail brush, still require subsequent manual or semi-automatic intervention in this solution. This not only increases production costs and labor expenses but also makes it difficult to guarantee product quality stability and consistency. Furthermore, this solution does not address integrated continuous production processes such as automated bending and intelligent bundling of the brush filaments; overall production efficiency and the degree of automation in process connections still need improvement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a shield tail brush filament rolling machine. Through the coordinated operation of a bundling mechanism, a filament rolling device, a cutting device, a driving device, and integrated combing and bending devices, and by introducing a closed loop consisting of a pressure sensor and an integrated control system, this machine achieves fully automated continuous production and online intelligent quality control of the entire process of brush filaments, from bundling, calendering, and fixed-length cutting to intelligent combing and precise bending.

[0016] A storage cabinet is provided under the cabinet, and a load-bearing beam is provided inside the cabinet. A strapping machine is installed on the load-bearing beam.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) This invention overcomes the technological challenge of efficient and non-destructive combing of wave bristles, greatly improving efficiency and protecting the integrity of the bristles: In response to the characteristic that the bristles are easy to entangle after embossing, this invention innovatively integrates two technologies: mechanical vibration to break adhesion and flexible self-adaptation of comb teeth. The design of the elastic baffle and the reset spring in the displacement component generates high-frequency micro-vibration during the combing process, which effectively breaks down the electrostatic adsorption and mechanical connection between the bristles, making them loose in advance. At the same time, the comb teeth are hinged through the movable column and can be deflected in a controlled manner. During combing, they can adaptively avoid resistance points and smooth uneven areas, avoiding bristle damage or pattern destruction caused by rigid combing. The two work together to significantly improve combing efficiency and effect while maximizing the protection of the physical and functional integrity of the bristles.

[0019] (2) This invention achieves a leap in intelligent closed-loop quality control and product quality consistency in the production process. By integrating pressure sensors at both ends of the bottom beam and linking them with the central control system, this invention constructs an online real-time monitoring and feedback system. This system can not only accurately measure the weight of the brush bristle bundle, but also perceive the uniformity of the bristle bundle distribution in real time through multi-point pressure differences. The control system dynamically adjusts the combing action based on this data, forming an intelligent closed loop of monitoring-analysis-execution-re-optimization. This fundamentally advances quality control from post-inspection to real-time process control, ensuring that each bundle of produced brush bristles reaches the optimal state of high straightness and uniform density, thereby ensuring the reliability and consistency of the sealing performance of the final shield tail brush product.

[0020] (3) This invention optimizes the production process through highly integrated design, improves equipment reliability and automation. This invention creatively integrates multiple functions such as clamping, transportation, bending guidance and unloading into a set of mechanisms including the opening and closing plate and the driving device. After the combing slide and the opening and closing plate have completed clamping and combing, they can directly serve as carriers to accurately transfer the bristle bundle to the bending station. During bending, the inner wall of the opening and closing plate naturally forms a bending guide surface and can adaptively open under bending pressure, reserving deformation space for bristle folding. After bending, it can be fully opened to automatically unload. This highly integrated design with multiple functions eliminates the need for additional transfer and special mechanisms, simplifies the equipment structure, reduces the failure rate, and realizes a smooth and fully automated production connection from combing to bending.

Therefore, they should not be construed as limitations on this invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Example 1: As Figures 4-16As shown, this embodiment provides a shield tail brush thread rolling machine, including a cabinet 1 and a bundle mechanism 2 on one side of the cabinet 1. A thread rolling mechanism 3 is provided on the cabinet 1. The thread rolling mechanism 3 includes a processing table 301 on the cabinet 1, an electrical control box 302 on the processing table 301, an integrated control system 303 on the electrical control box 302, a thread rolling device 31 on the processing table 301, a cutting device 32 on one side of the thread rolling device 31, and a drive mechanism on one side of the cutting device 32. Device 33, the drive device 33 is equipped with a combing device 34 and a bending device 35; the drive device 33 includes: a drive base plate 331, which is mounted on the processing table 301; a drive frame 332, which is fixedly connected to the drive base plate 331; a drive motor 3321, which is mounted on one side of the drive frame 332; and a drive screw 3322, which is movably connected inside the drive frame 332; the comb... The processing device 34 includes: a combing slide plate 341, which is movably connected to the drive frame 332; two sets of bottom beams 3411 located under the combing slide plate 341; a drive nut 3412 mounted on the two sets of bottom beams 3411; two sets of pressure sensors 3413 embedded at both ends of the bottom beams 3411; and two sets of opening and closing plates 342, which are movably connected inside the combing slide plate 341. 42 are symmetrically distributed; limiting edge 3421 is provided on both sides of the opening and closing plate 342; opening and closing end 3422 is provided at the contact end of the two sets of opening and closing plates 342; movable end 3423 is provided at the other end of the two sets of opening and closing plates 342; torque plate 3424 is provided on the movable end 3423; the combing slide plate 341 is provided with positioning component 343, displacement component 344, adjustment component 345 and combing component 346.

[0042] In this embodiment, the entire automated operation of the wire rolling machine is centrally controlled by the electrical control box 302 and the integrated control system 303, including motor start / stop, cylinder action, cutting sequence, etc. Four sets of pressure sensors 3413 on the bottom beam 3411 can detect the weight of the brush segments in real time, ensuring the accuracy of brush segment feeding. Simultaneously, the different data detected by the four sets of pressure sensors 3413 distributed at the four corners indicates the distribution of the brush segments, and the integrated control system 303 makes subsequent adjustments. The drive device 33, through the cooperation of the drive screw 3322 and the drive nut 3412, drives the motor... The rotational motion of 3321 is converted into the precise linear reciprocating motion of the combing slide plate 341 along the drive frame 332, thereby realizing the collection and moving of the brush filaments after the filaments have been rolled. The brush filaments are then transported to the bending device 35 for bending. During bending, the cylinder on the bending device 35 drives the pressure knife to move down and contact the center of the brush filament segment and apply pressure, causing the brush filament segment to bend and fold into two segments. The pressure pushes open the two sets of opening and closing plates 342 to create a pre-reserved deformation space for the brush filament segment to fold and stand upright. At the same time, the two sets of opening and closing plates 342 guide and restrict the brush filament segment during bending, and allow the brush filament segment to move down for unloading.

[0043] The thread rolling device 31 includes: a rubber roller 311, which is mounted on the processing table 301; a thread rolling base 312, which is located on one side of the rubber roller 311; two sets of thread rolling rollers 313, which are movably connected to the thread rolling base 312; a thread rolling motor 314, which is mounted on the thread rolling base 312; and two sets of adjusting cylinders 315, which are located on the thread rolling base 312.

[0044] In this embodiment, the brush bristles are continuously pulled and moved to the subsequent work station by the contact friction between the rubber roller 311 and the brush bristles. When the brush bristles pass through the rolling roller 313, they are subjected to the pressure teeth on the two sets of rolling roller 313, which roll the brush bristles in both directions to form a wave-like bend. The two sets of adjusting cylinders 315 adjust the distance between the two sets of rolling roller 313 in real time, thereby adapting to the processing of brush bristles of different diameters or controlling the rolling depth to ensure the consistency of the brush bristle pattern.

[0045] The cutting device 32 includes: a cutting seat 321, which is located on one side of the thread rolling base 312; a hydraulic cylinder 322, which is located on the cutting seat 321; a cutting tool 323, which is movably connected to the lower part of the cutting seat 321; a trapezoidal material collection frame 324, which is located at the material feeding end of the cutting seat 321; and a limiting plate 325, which is located inside the trapezoidal material collection frame 324.

[0046] In this embodiment, the hydraulic cylinder 322 provides strong instantaneous downward pressure, driving the cutting tool 323 to quickly complete the cutting action, ensuring a flat cut. The trapezoidal collecting frame 324 is used to receive and bundle the fed brush filaments. Its trapezoidal structure facilitates the brush filaments to slide and gather. The internal limiting plate 325 can adjust the width of the effective outlet of the trapezoidal collecting frame 324 to prevent the brush filaments from becoming disordered during the accumulation process, so that they can enter the next sorting or bundling process in an orderly manner.

[0047] The drive device 33 further includes: a drive gear 3323, two sets of drive gears 3323 are respectively located at one end of the drive screw 3322 and the drive motor 3321, and the two sets of drive gears 3323 mesh; a guide rod 3324, which is connected through the drive frame 332; a guide frame 333, which is fixedly connected to the drive frame 332; a guide inclined plate 3331, two sets of guide inclined plates 3331 are located on the guide frame 333; and a guide roller 334, which is located on one side of the guide frame 333.

[0048] In this embodiment, the drive gear 3323 forms a speed reduction and transmission mechanism between the drive motor 3321 and the drive screw 3322, which can realize speed adjustment and increase torque; the guide rod 3324 is arranged parallel to the drive screw 3322, and the combing slide plate 341 cooperates with the screw nut and the guide rod 3324 to ensure the smoothness and linear accuracy of its movement process and prevent jamming; the guide frame 333 and the guide inclined plate 3331 and guide roller 334 on it together form the guide channel for the brush filaments to enter the combing device 34.

[0049] The positioning component 343 includes: a positioning frame 3431, two sets of positioning frames 3431 are mounted on the combing slide plate 341; a positioning cylinder 3432, the positioning cylinder 3432 is mounted on the positioning frame 3431; and a positioning pressure plate 3433, the positioning pressure plate 3433 is located below the output end of the positioning cylinder 3432.

[0050] In this embodiment, the positioning component 343 is used to press and fix the ends of the bristle bundle before the combing action begins. The two positioning frames 3431 are arranged symmetrically. When the bristle bundle is sent to the predetermined position, the positioning cylinder 3432 extends and drives the positioning pressure plate 3433 to move downward, firmly pressing the ends of the bristle bundle against the combing slide plate 341 or the designated anvil, preventing the bristles from moving during the subsequent combing process and ensuring the accuracy of the starting position of combing.

[0051] The displacement assembly 344 includes: a displacement slide rail 3441, two sets of displacement slide rails 3441 are fixedly connected to both sides of the combing slide plate 341; a lifting slide rail 3442, the lifting slide rail 3442 is connected to the lower part of the displacement slide rail 3441; a displacement motor 3443, the displacement motor 3443 is installed at one end of the displacement slide rail 3441; a displacement lead screw 3444, the displacement lead screw 3444 is connected through the displacement slide rail 3441; and a displacement slider 3445, the displacement slider 3445 is movably connected to the displacement slide rail 3441. 441 Inside; displacement nut 3446, displacement nut 3446 is movably connected to one side of displacement slider 3445; return spring 3447, return spring 3447 is fixedly connected inside displacement slider 3445, the other end of return spring 3447 is fixedly connected to displacement nut 3446; elastic stop plate 3448, multiple sets of elastic stop plates 3448 are fixedly connected to both sides of the inner wall of displacement slide rail 3441; lifting spring plate 3449, lifting spring plate 3449 is set inside lifting slide rail 3442.

[0052] In this embodiment, the displacement component 344 is responsible for carrying and driving the adjustment component 345 and the combing component 346 to perform a combined lateral movement along the Y-axis and a vertical movement along the Z-axis. The displacement motor 3443 drives the displacement slider 3445 to move precisely along the displacement slide rail 3441 via the displacement lead screw 3444 and the displacement nut 3446. The return spring 3447 connects the displacement nut 3446 and the displacement slider 3445 to form an elastic connection. When the displacement slider 3445 contacts the equidistantly spaced elastic resistance plates 3448 during its movement, it will experience frictional resistance. The moving speed is reduced until the deformation pressure of the return spring 3447 overcomes the resistance, thereby generating vibration. The vibration of the combing assembly 346 breaks the static state of the bristles, improving the combing effect of the combing assembly 346 during subsequent combing. At the same time, the use of the return spring 3447 provides a buffer when the combing assembly 346 encounters unexpected resistance, preventing damage to the mechanism. The lifting slide rail 3442 cooperates with the lifting spring plate 3449 to allow the adjustment assembly 345 and the combing assembly 346 to be adjusted and raised at designated bending positions, ensuring adaptation to the bending operation of the bristle section.

[0053] The adjusting assembly 345 includes: an assembly plate 3451, which is mounted on the displacement slider 3445; a deflection motor 3452, which is mounted on the assembly plate 3451; a deflection column 3453, which is movably connected to the assembly plate 3451; a telescopic sleeve 3454, which is fixedly connected to the outer wall of the deflection column 3453; a telescopic slide plate 3455, which is movably connected to one end of the telescopic sleeve 3454; a telescopic motor 3456, which is mounted on one side of the telescopic sleeve 3454; a telescopic gear 3457, which is located at one end of the output shaft of the telescopic motor 3456; a rack 3458, which is fixedly connected to the inner wall of the slide groove of the telescopic slide plate 3455; and a displacement cylinder 3459, which is mounted on one side of the telescopic slide plate 3455.

[0054] In this embodiment, the adjustment component 345 provides the combing component 346 with multi-degree-of-freedom position and posture adjustment capabilities. The deflection motor 3452 can drive the deflection column 3453 to rotate, thereby causing the entire end effector to deflect around its axis by a certain angle to adapt to the tilt of the bristle bundle or to perform special combing actions. At the same time, the combing component 346 can be folded back without affecting the feeding and stacking of the bristle segments. The telescopic motor 3456 drives the telescopic slide plate 3455 to telescopically move relative to the telescopic sleeve plate 3454 through the meshing of the telescopic gear 3457 and the rack 3458, realizing the fine adjustment of the position of the combing component 346 in the X-axis direction, ensuring that the combing component 346 can be raised and lowered and penetrate the bristle bundle to ensure the combing effect. The displacement cylinder 3459 is used to drive the combing component 346 to perform a short-stroke rapid advance or retraction action, which can extend and splice the combing components 346 on both sides to increase the combing range and thus improve the combing efficiency.

[0055] The combing assembly 346 includes: a track plate 3461, which is fixedly connected to the other side of the telescopic slide plate 3455; a combing plate 3462, which is movably connected to the track plate 3461; a track groove 3463, which is disposed on the track plate 3461; a metal connecting end 3464, which is disposed at one end of the combing plate 3462; a movable groove 3465, which is opened on the combing plate 3462; comb teeth 3466, with multiple sets of comb teeth 3466 disposed in the movable groove 3465; movable columns 3467, with two sets of movable columns 3467 disposed on both sides of the comb teeth 3466; a traction plate 3468, which is fixedly connected to one side of the multiple sets of comb teeth 3466; and an electromagnet 3469, which is disposed at one end of the traction plate 3468.

[0056] In this embodiment, the combing component 346 is the end tool that directly performs the combing action. The combing plate 3462 is driven by the displacement cylinder 3459 and can slide along the track groove 3463 on the track plate 3461. The multiple sets of comb teeth 3466 are combing functional components. They are not completely rigidly fixed, but are installed in the movable groove 3465 through the movable column 3467, so that they have a certain amount of mobility. When combing the tangled brush filaments, they can avoid them and reduce damage. The traction plate 3468 connects the multiple sets of comb teeth 3466 together. When the electromagnet 3469 is energized, it generates magnetic force, which drives the traction plate 3468 by adsorbing the metal connection end 3464 or by direct action. This drives all the comb teeth 3466 as a whole to perform combing actions such as beating and turning, straightening the possibly messy brush filament bundles after cutting.

[0057] Meanwhile, the activation or deactivation of the electromagnet 3469 determines the activity state of the multiple comb teeth 3466. When the power is off, the multiple comb teeth 3466 move with the combing assembly 346. Affected by the frictional resistance of the bristle segments, the multiple comb teeth 3466 will make appropriate deflections. In conjunction with the height adjustment of the telescopic motor 3456, the unevenly stacked bristle segments can be smoothed out, ensuring that the bristle segments are evenly distributed. The uniformity of the bristle distribution is detected in real time by four sets of pharmacological sensors 3413 through pressure.

[0058] Example 2: Figures 1-3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0059] The bundling mechanism 2 includes a material rack 201 located on one side of the cabinet 1. Multiple sets of material plates 202 are fixedly connected to the material rack 201. Multiple sets of material rolls 203 are movably connected to the multiple sets of material plates 202. Multiple sets of tensioning shafts 204 are movably connected to one end of the material rack 201. Tensioning wheels 205 are provided at both ends of the multiple sets of tensioning shafts 204. A crossbeam 206 is fixedly connected to one end of the material rack 201. A guide wheel set 207 and a guide plate 208 are provided on the crossbeam 206.

[0060] In this embodiment, the bundling mechanism 2 is the raw material supply unit of the equipment, used to combine, guide, and transport multiple rolls of brush filaments to the rolling mechanism 3. Multiple sets of material rolls 203 are respectively installed on the material plate 202 and can be unwound independently. Multiple brush filaments pass through a tensioning system composed of a tensioning shaft 204 and a tensioning wheel 205. This system provides stable and appropriate tension to each brush filament through friction or an adjustable resistance mechanism, preventing the brush filaments from becoming loose or tangled, and ensuring the stability of synchronous conveying of multiple filaments. The guide wheel group 207 on the crossbeam 206 performs the final horizontal and vertical positioning of the brush filaments. The guide plate 208 is provided with guide holes corresponding to the number of brush filaments, which precisely align and bundle multiple brush filaments to form a neatly arranged bundle of brush filaments, which is then fed into the rolling device 31.

[0061] A storage cabinet 101 is installed under the cabinet 1, and a load-bearing beam 102 is installed inside the cabinet 1. A strapping machine 103 is installed on the load-bearing beam 102.

[0062] In this embodiment, the cabinet 1 serves as the supporting structure for the overall equipment. The storage cabinet 101 below can be used to store tools, spare parts, or packaging materials. The load-bearing beam 102 inside the cabinet 1 enhances the structural strength and provides a stable mounting point for the bundling machine 103. The bundling machine 103 is located downstream of the wire rolling and combing process. Its function is to automatically bundle the straightened bristles obtained after wire rolling, cutting, and combing with wire or cable ties to form a specified number of bundles of semi-finished products, which are convenient for subsequent transportation and assembly into the final shield tail brush seal.

[0063] Work steps

[0064] Step 1, feeding and bundling process: Multiple rolls 203 containing brush filaments are respectively installed onto the material plate 202 of the bundling mechanism 2. Each brush filament head is pulled to pass through the tensioning system composed of tensioning shaft 204 and tensioning wheel 205 in sequence. This system provides stable and appropriate tension for each brush filament to prevent loosening or tangling. Subsequently, the brush filaments are finally positioned and bundled by the guide wheel group 207 and guide plate 208 on the crossbeam 206 to form a neatly arranged bundle of brush filaments.

[0065] Step 2, Thread Rolling Process: The bundled brush filaments are fed into the thread rolling device 31 at a uniform speed under the frictional pull of the rubber roller 311. The thread rolling motor 314 is started, driving two sets of thread rolling rollers 313 with engraved patterns to rotate in opposite directions. When the brush filaments pass through, they are rolled in both directions by the pressure teeth on the thread rolling rollers 313 to form a specific wavy pattern. During this process, two sets of adjusting cylinders 315 can adjust the gap pressure between the thread rolling rollers 313 in real time to accurately control the rolling depth and ensure the consistency and high quality of all brush filament patterns.

[0066] Step 3, Cutting process: The continuously formed wavy brush ribbon is conveyed forward to the set length and is guided by the trapezoidal collection frame 324 into the cutting device 32. The internal limiting plate 325 prevents the brush ribbon from becoming disordered and makes it stacked in an orderly manner. The integrated control system 303 issues a command, and the hydraulic cylinder 322 of the cutting device 32 drives the cutting blade 323 to cut down quickly, cutting the brush ribbon with a flat cut.

[0067] Step 4, Collection and Sorting Process: The cut bristle segments fall into the central area of ​​the combing slide plate 341 through the guide roller 334 and the guide inclined plate 3331, that is, on the two sets of opening and closing plates 342 for centralized collection. The four sets of pressure sensors 3413 embedded at both ends of the bottom beam 3411 detect the weight of the clamped bristle segments in real time. This data is fed back to the integrated control system 303 to confirm whether the feeding quantity is accurate. By analyzing the differences in the data of the four corner pressure sensors, the system can determine whether the distribution of the bristle segments in the opening and closing plates 342 is uniform, providing a basis for subsequent intelligent combing.

[0068] When the electromagnet 3469 of the combing component 346 is de-energized, the multiple comb teeth 3466 are in a freely deflectable state. Driven by the deflection motor 3452 and the displacement component 344, the comb teeth 3466 move in the bristle bundle. When encountering resistance, the comb teeth 3466 adaptively deflect and avoid the resistance in the movable groove 3465 through the movable column 3467, reducing damage to the steel wire. At the same time, they smooth out raised or sparse areas. Throughout the combing process, the pressure sensor 3413 continuously monitors the pressure distribution changes, forming a closed loop of detection-combing-re-detection. The integrated control system 303 dynamically adjusts the combing path and force according to real-time data until the bristle bundle is completely straight and evenly distributed, and the sensor data reaches equilibrium.

[0069] Step 5, Preparation process: The positioning cylinder 3432 of the positioning component 343 drives the positioning pressure plate 3433 to press down, fixing the two ends of the bristle segment;

[0070] The telescopic motor 3456 drives the combing assembly 346 to lift and lower as a whole through the telescopic gear 3457 and rack 3458 mechanism, so that the combing plate 3462 can extend and retract to adapt to the thickness of the bristle section;

[0071] The deflection motor 3452 drives the deflection column 3453 to rotate, thereby causing the entire end effector to deflect around its axis by a certain angle, deflecting the combing plate 3462 upward and perpendicular to the bristle section, so as to adapt to the tilt of the bristle bundle or to perform special combing actions.

[0072] The displacement cylinder 3459 of the adjustment component 345 is activated, pushing the combing plates 3462 of the combing components 346 on both sides to extend and splice along the track groove 3463, expanding the combing range. Then, the telescopic motor 3456 is driven in the opposite direction to make the combing plates 3462 retract and descend, and to move the comb teeth 3466 to be able to penetrate the bristle bundle.

[0073] Step Six, Combing Process: The displacement component 344 starts working, and the displacement motor 3443 drives the displacement slider 3445 to move laterally back and forth with the combing component 346. The combing component 346 combs the brush bristles by moving back and forth within the bristle section, and organizes the brush bristle bundles that may be messy, bent or tangled after rolling and cutting into a straight, uniform and orderly state, thereby ensuring the sealing performance, service life and consistency of the final shield tail brush product.

[0074] During the movement, the displacement slider 3445 will intermittently contact the elastic baffle 3448 on the inner wall of the displacement slide rail 3441, generating frictional resistance. This resistance is converted into high-frequency micro-vibration of the entire combing assembly 346 through the deformation and release of the return spring 3447. This vibration can effectively break the electrostatic adsorption or slight entanglement between the steel wires, making the bristle bundle loose, thereby effectively improving the combing efficiency while reducing damage to the bristles.

[0075] When the electromagnet 3469 of the combing component 346 is de-energized, the multiple comb teeth 3466 are in a state of free deflection. When encountering resistance during movement, the comb teeth 3466 adaptively deflect and avoid resistance in the movable groove 3465 through the movable column 3467, thereby reducing damage to the steel wire.

[0076] Step 7, bending process: After the combing is completed, the drive device 33 is started again, and the combing slide 341 holding the combed and straightened brush filament bundle is precisely moved to the working position of the bending device 35.

[0077] The cylinder of the bending device 35 drives the pressure knife to move downward and apply pressure to the center of the brush filament bundle. During the pressing process, the pressure first pushes open the two sets of opening and closing plates 342, leaving space for the bending deformation of the brush filament bundle. The inner wall of the opening and closing plates 342 also guides and restricts the bending process of the brush filament bundle, ensuring that the bending shape is regular. Under the continuous action of pressure, the middle part of the brush filament bundle is bent and folded to form two sections.

[0078] After the bending action is completed, the opening and closing plate 342 is fully opened, and the folded brush filament bundle automatically falls off under the action of gravity, completing the unloading.

[0079] Step 8, Bundling Process: After unloading, the formed brush filament bundles fall into the working area of ​​the bundling machine 103 located at the end of the equipment. The bundling machine 103 automatically bundles the bent brush filament bundles with wire or cable ties to form neat bundled semi-finished products. The bundled products can be collected in the storage cabinet 101 or directly transferred for subsequent assembly into complete shield tail brush seals.
