Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of brush manufacturing, and more specifically, to a filament twisting device for brush manufacturing. Background Technology

[0002] In brush production, the twisting process is the core step in combining materials such as fiber filaments and bristles into bundles. The tightness and regularity of the twisted filament bundles directly determine the durability and performance of the brush, while the performance of the twisting device affects production efficiency and product consistency. As the brush industry develops towards refinement and large-scale production, the shortcomings of traditional brush twisting equipment have become increasingly apparent: existing equipment produces poorly tight filament bundles after twisting, easily resulting in misalignment and disorder, and lacks an integrated winding function after twisting, making direct winding inconvenient and severely restricting the production process and product quality.

[0003] The core drawback of traditional yarn twisting equipment stems from insufficient structural design: On the one hand, the lack of precise guiding and clamping mechanisms results in uneven stress on the fibers and bristles during twisting, with some fibers not being fully wrapped and adhered, leading to loose yarn bundles and easy shedding during use. Simultaneously, the absence of a regularized structure during twisting makes the yarn bundles prone to axial misalignment and radial disorder, affecting the accuracy of subsequent fiber implantation processes. On the other hand, existing equipment focuses solely on the twisting function and lacks an integrated winding module. After twisting, the yarn bundles must be manually transferred to the winding equipment, which is prone to secondary entanglement and disarray during the transfer process, increasing labor intensity and extending the production cycle.

[0004] Therefore, developing a filament twisting device for brush production that can improve the tightness and regularity of filament twisting and has a direct winding function has become an urgent need to solve the pain points of traditional equipment and optimize the brush production process. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a filament twisting device for brush production, which solves the technical problems of poor filament tightness after twisting, easy misalignment and disorder, and lack of integrated winding function after twisting, making it inconvenient to directly wind up.

[0006] According to one aspect, at least one embodiment of this disclosure provides a filament twisting device for brush production, comprising: The equipment frame and the upright plate, wherein the upright plate is fixed to the surface of the equipment frame; A wire twisting assembly, wherein the wire twisting assembly is disposed on the equipment frame and the upright plate; The rear groove and the winding assembly are provided, wherein the rear groove is formed on the side surface of the equipment frame and the winding assembly is disposed in the rear groove; The wire twisting assembly includes a rotating disk, which is rotatably mounted inside the vertical plate. The rotating disk has several wire twisting holes on its surface and a boss on its side surface. The boss has several anti-deviation grooves on its surface, and the number and position of the anti-deviation grooves correspond to the wire twisting holes.

[0007] As a further technical solution, an external gear is provided around the outer surface of the rotating disk, and a drive gear that is driven to rotate by electricity is provided on the side surface of the vertical plate. The drive gear meshes with the external gear, and a fixed seat is provided on the surface of the equipment frame.

[0008] As a further technical solution, a shaped cluster cover is installed on the fixed base, and a vertical frame is provided on the surface of the equipment frame. A pair of pressing wheels are rotatably connected inside the vertical frame. The pair of pressing wheels are vertically distributed up and down, and the pair of pressing wheels are a cam and a concave wheel, respectively.

[0009] According to another aspect, in at least one embodiment of the present invention, the winding assembly includes a pair of side grooves, the side grooves being formed on both sides of the rear groove, and telescopic cylinders being horizontally installed on both sides of the rear groove, with the output end of the telescopic cylinders connected to a movable frame.

[0010] As a further technical solution, the movable frame is located in the rear groove, and rotating inner seats are rotatably connected to the side surfaces of the movable frame. A take-up reel is fitted between the rotating inner seats, and one of the rotating inner seats on one side is driven to rotate by electricity.

[0011] As a further technical solution, a pair of retaining rotating columns are vertically rotatably connected in the rear groove, and the retaining rotating columns are located at the middle position relative to the take-up reel.

[0012] As a further technical solution, support wheels are rotatably connected to both sides of the rear groove, and the support wheels are attached to the bottom ends of the take-up reel.

[0013] As a further technical solution, the front end of the molded cluster cover has a trumpet-shaped opening structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the wire twisting assembly solves the problems of poor wire twisting tightness and easy misalignment in traditional equipment through multi-structure collaborative design. The wire twisting holes of the rotating disk correspond to the anti-deviation grooves, ensuring that the metal wires are twisted along a preset trajectory and avoiding deviation and disorder; the gear transmission drives the rotating disk to rotate at a uniform speed, ensuring uniform twisting density and improving the tightness of the bristle bundle; the forming bundle cover regularizes the twisting shape, and the trumpet-shaped opening facilitates the introduction of wires; the pressure wheel, which cooperates with the cam and concave wheel, provides appropriate pressure, further enhancing the twisting firmness and preventing loosening.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3 As shown, a filament twisting device for brush production according to an embodiment of the present disclosure is illustrated, comprising: The equipment frame 1 and the upright plate 2 are fixed to the surface of the equipment frame 1; A wire twisting assembly 4 is disposed on the equipment frame 1 and the upright plate 2; The rear groove 3 and the winding assembly 5 are provided. The rear groove 3 is formed on the side surface of the equipment frame 1, and the winding assembly 5 is disposed in the rear groove 3. The wire twisting assembly 4 includes a rotating disk 4-1, which is rotatably mounted inside the vertical plate 2. The rotating disk 4-1 has several wire twisting holes 4-2 on its surface. The rotating disk 4-1 has a boss 4-3 on its side surface, and the boss 4-3 has several anti-deviation grooves 4-4 on its surface. The number and position of the anti-deviation grooves 4-4 correspond to the wire twisting holes 4-2. An external gear 4-5 is arranged around the outer surface of the rotating disk 4-1. A drive gear 4-6, which is electrically driven to rotate, is arranged on the side surface of the vertical plate 2. The drive gear 4-6 meshes with the external gear 4-5. A fixed seat 4-7 is arranged on the surface of the equipment frame 1. A shaped bundle cover 4-8 is installed on the fixed seat 4-7. A vertical frame 4-9 is arranged on the surface of the equipment frame 1. A pair of pressure rollers 4-10 are rotatably connected inside the vertical frame 4-9. The pair of pressure rollers 4-10 are vertically distributed and are a cam and a concave roller, respectively.

[0024] In some examples, in order to achieve uniform twisting and stable forming of brush filaments and avoid uneven product quality caused by filament deviation and loosening during the twisting process, a twisting assembly 4 is designed. This assembly includes a rotating disk 4-1 in the rotating set inside the upright plate 2, which provides the core rotating component for twisting. Several twisting holes 4-2 on its surface allow multiple brush filaments to pass through, and when rotating, it drives the filaments to twist around the central axis.

[0025] The boss 4-3 on the side surface of the rotating disk 4-1 and the anti-deviation groove 4-4 at the corresponding position of the wire twisting hole 4-2 can laterally limit the wire material entering the wire twisting hole 4-2, prevent the wire material from deviating from the hole opening and rubbing against the hole wall during the twisting process, and ensure that each wire material participates in the twisting along the preset trajectory. The external gear 4-5 on the outer surface of the rotating disk 4-1 meshes with the electrically driven drive gear 4-6 on the side surface of the vertical plate 2, forming a stable transmission structure. When the drive gear 4-6 rotates, it synchronously drives the external gear 4-5 and the rotating disk 4-1 to rotate. The rotation speed of the rotating disk 4-1 is controlled by the precision of the gear transmission, avoiding uneven twisting density caused by speed fluctuations.

[0026] The forming bundle cover 4-8 on the surface fixing seat 4-7 of the equipment frame 1 can further regulate the stranded wires, ensure the uniformity of the cross-sectional shape of the stranded wires, and reduce external interference.

[0027] The pair of vertically distributed pressure rollers 4-10 (cam and concave roller) rotatably connected inside the frame 4-9 can moderately press the formed stranded wire, enhance the stranding firmness of the wire, and prevent loosening during subsequent winding. The matching design of the cam and concave roller can be adapted to stranded wires of different diameters, ensuring uniform pressing force without damaging the wire.

[0028] The rotational cooperation between the rotating disk 4-1 and the vertical plate 2 ensures smooth rotation, the corresponding design of the anti-deviation groove 4-4 and the twisting hole 4-2 ensures accurate guidance, and the synergistic effect of gear transmission and pressure wheel 4-10 improves twisting stability.

[0029] During operation, the drive gear 4-6 drives the rotating disk 4-1 to twist the filaments, the anti-deviation groove 4-4 guides, the forming bundle cover 4-8 straightens, and the pressure wheel 4-10 reinforces. The multi-structure collaboration achieves stable twisting and forming, meeting the filament twisting requirements of brush production.

[0030] like Figures 1-3 As shown, this embodiment proposes that the winding assembly 5 includes a pair of side grooves 5-1, which are opened on both sides of the rear groove 3. Telescopic cylinders 5-2 are horizontally installed on both sides of the rear groove 3. The output end of the telescopic cylinders 5-2 is connected to a movable frame 5-3, which is located in the rear groove 3. Rotating inner seats 5-4 are rotatably connected to the side surface of the movable frame 5-3. A winding reel 5-5 is fitted between the rotating inner seats 5-4, and one of the rotating inner seats 5-4 is driven to rotate by electricity.

[0031] In some examples, in order to achieve stable winding of stranded yarn and quick loading and unloading of winding reel 5-5, and to avoid yarn deviation during winding or cumbersome disassembly and assembly of winding reel 5-5 affecting production efficiency, a winding assembly 5 is designed. This assembly includes side grooves 5-1 on both sides of the rear groove 3 to provide horizontal sliding guide for the moving frame 5-3. Telescopic cylinders 5-2 installed horizontally on both sides can drive the moving frame 5-3 to move closer or further away from the side grooves 5-1 in sync, thereby adjusting the distance between the two moving frames 5-3 to adapt to winding reels 5-5 of different widths. Multi-specification winding needs can be met without replacing the assembly.

[0032] The rotating inner seat 5-4, which is rotatably connected to the side surface of the movable frame 5-3, can support both ends of the winding reel 5-5. The rotating inner seat 5-4, which is electrically driven on one side, can drive the winding reel 5-5 to rotate, thereby realizing the automatic winding of the stranded yarn. The stability of the rotation drive ensures that the winding speed is uniform and avoids the yarn being wound too loosely or too tightly.

[0033] The winding reel 5-5 is fixed by being fitted between the two rotating inner seats 5-4. When the telescopic cylinder 5-2 drives the moving frame 5-3 away, the distance between the rotating inner seats 5-4 can be widened, making it easier to take out the old winding reel 5-5 and install the new winding reel 5-5. When the moving frame 5-3 approaches, the rotating inner seats 5-4 fit tightly against both ends of the winding reel 5-5, ensuring that there is no radial wobbling when the winding reel 5-5 rotates, and ensuring the stability of the winding process.

[0034] The guiding function of the side groove 5-1 makes the sliding frame 5-3 slide smoothly and avoids misalignment between the rotating inner seat 5-4 and the take-up reel 5-5; the synchronous drive design of the telescopic cylinder 5-2 ensures that the spacing adjustment of the two sides of the sliding frame 5-3 is symmetrical and prevents the take-up reel 5-5 from being installed tilted.

[0035] During operation, the telescopic cylinder 5-2 adjusts the spacing between the moving frame 5-3 and the winding reel 5-5, driving the rotating inner seat 5-4 to rotate the winding reel 5-5. After winding is complete, the cylinder drives the spacing to expand and disassemble the winding reel 5-5. The cylinder adjustment adapts to multiple specifications, facilitating easy disassembly and assembly and improving efficiency. All components work together to achieve stable winding and quick maintenance, meeting the winding needs of brush production.

[0036] For example, such as Figure 1 As shown, a pair of retaining rotating columns 6 are vertically rotatably connected inside the rear groove 3, and the retaining rotating columns 6 are located at the middle position relative to the take-up reel 5-5.

[0037] In some examples, a pair of retaining rotating posts 6 are vertically rotatably connected within the rear groove 3 and are located in the middle of the take-up reel 5-5, forming a guiding constraint from both sides of the stranded wire take-up path. The retaining rotating posts 6 rotate synchronously with the stranded wire take-up, which can reduce frictional damage between the wire and the posts, and at the same time prevent the stranded wire from shifting to both sides during take-up, ensuring that the wire is evenly wound on the take-up reel 5-5 and avoiding local accumulation or loose winding.

[0038] For example, such as Figure 1 As shown, support wheels 7 are rotatably connected to both sides of the rear groove 3, and the support wheels 7 are attached to the bottom ends of the take-up reel 5-5.

[0039] In some examples, the support wheels 7, which are rotatably connected to both sides inside the rear groove 3, fit against the bottom ends of the take-up reel 5-5. This provides bottom support for the take-up reel 5-5, distributing the pressure of the weight of the take-up reel 5-5 and the stranded wire on the rotating inner seat 5-4, reducing wear on the rotating inner seat 5-4, and extending the service life of the components. The support wheels 7 rotate synchronously with the take-up reel 5-5, which can reduce the frictional resistance when the take-up reel 5-5 rotates, ensuring a stable winding speed. At the same time, it prevents the take-up reel 5-5 from tilting due to its own weight, ensuring stability during the winding process.

[0040] For example, such as Figure 1As shown, the front end of the molded cluster cover 4-8 has a trumpet-shaped opening structure.

[0041] In some examples, the trumpet-shaped opening at the front end of the forming bundle cover 4-8 expands the range for the filament to enter, facilitating the smooth entry of the twisted filament into the cover and avoiding the problem of inaccurate entry due to slight filament misalignment. The trumpet-shaped opening gradually narrows inward into the cover, guiding the twisted filament to gradually conform to the preset path, ensuring that the filament enters the subsequent pressing rollers 4-10 in a stable posture, thus improving the forming effect.

[0042] In practical use: Multiple metal wires are passed through the twisting holes 4-2 of the rotating disk 4-1. The ends of the wires are guided by the anti-deviation grooves 4-4 of the boss 4-3, and then pass through the forming bundle cover 4-8 and the pressing wheel 4-10 (cam and concave wheel) inside the upright frame 4-9, and finally fixed on the take-up reel 5-5. The twisting assembly 4 is started, and the drive gear 4-6 meshes with the external gear 4-5 of the rotating disk 4-1, causing the rotating disk 4-1 to rotate. Under the action of rotation, the metal wires are twisted into a tight bristle bundle. The forming bundle cover 4-8 regularizes the twisted shape, and the pressing wheel 4-10 further presses and strengthens the firmness. At the same time, the take-up assembly 5 is started. The telescopic cylinder 5-2 adjusts the distance of the moving frame 5-3 so that the rotating inner seat 5-4 clamps the take-up reel 5-5. The electric drive of the rotating inner seat 5-4 drives the take-up reel 5-5 to rotate, and the twisted bristle bundle is evenly wound up. The rotating column 6 is kept in place to prevent the wire from deviating, and the support wheel 7 assists in supporting the take-up reel 5-5. After winding is completed, the telescopic cylinder 5-2 drives the moving frame 5-3 away, and the winding reel 5-5 can be removed. The entire process realizes the continuous operation of twisting, forming and winding.
