Description

Technical Field

[0001] This utility model relates to the field of brush bristle processing technology, and more specifically, it relates to a bristle take-up device for brush bristle processing. Background Technology

[0002] Brush filaments are fine filaments made of materials such as nylon, PP, and PBT, and are widely used in industrial brushes, cleaning brushes, and beauty brushes. Their manufacturing process includes extrusion, stretching, slitting, and winding, resulting in filaments that are wear-resistant, corrosion-resistant, and highly flexible. Depending on the application, parameters such as the diameter, hardness, and color of the brush filaments can be customized to meet the needs of different scenarios, such as polishing, dust removal, and surface treatment.

[0003] Existing brush filaments are mainly wound up by a set of take-up wheels during the filament winding process. For example, the filament winding device for brush filament processing provided in patent documents such as CN212151126U and CN221777300U requires the filament spool to be disassembled and a new take-up wheel to be installed after winding is completed. During the unloading and reloading of the take-up wheel, the operation needs to be stopped, which affects the efficiency of brush filament winding. In addition, in the existing technology, after replacing the new take-up wheel, the ends of the brush bristles need to be manually wrapped around the take-up wheel to fix the brush bristles, which is not convenient for automated operation. Furthermore, after fixing the brush bristles to the new take-up wheel, there is no corresponding fixing structure, which makes it easy for the connection between the brush bristles and the take-up wheel to loosen and detach, affecting the brush bristle take-up effect. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a brush filament taking-up device to solve the technical problems mentioned in the background art, such as low brush filament taking-up efficiency, the need for manual filament feeding, easy loosening, and affecting the filament taking-up effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a wire take-up device for brush filament processing, including a take-up frame. Two take-up shafts are staggered vertically on the take-up frame via bearings, and a drive assembly is provided in conjunction with the take-up shafts. A take-up wheel is mounted on the take-up shaft. A mounting frame is provided at the feed end of the take-up frame via an XYZ three-axis drive platform. A fixed clamping plate is provided on the side of the mounting frame near the take-up wheel. A movable clamping plate is provided at the bottom of the fixed clamping plate. A first electric push rod is provided on the fixed clamping plate in conjunction with the movable clamping plate. A cutting frame is movable along the XY direction on the side of the fixed clamping plate near the take-up wheel. A cutting blade is provided at the bottom of the cutting frame. A hot press plate is provided on the side of the cutting frame near the fixed clamping plate. A guide wheel is movably adjustable on the feed end side of the mounting frame. A clamping frame is provided on the take-up wheel.

[0006] Preferably, the take-up frame is equipped with a guide frame, the guide frame is equipped with a ball screw, and a screw nut and a screw motor are provided in conjunction with the ball screw. The guide wheel is mounted on the screw nut through a bracket structure. When the screw motor is started, the ball screw is controlled to reciprocate, so that the screw nut can carry the guide wheel to reciprocate relative to the take-up wheel, thereby achieving uniform winding of the brush filaments when they are taken up on the take-up wheel.

[0007] Preferably, the mounting bracket is equipped with a vision tracking camera, which can locate the position of the brush filaments during cutting, thereby enabling more precise clamping and fixing of the brush filaments and subsequent cutting operations.

[0008] Preferably, the top of the cutting frame is provided with a second electric push rod, the second electric push rod is provided with a moving block, and a movable telescopic structure is provided between the moving block and the fixed clamping plate. When the second electric push rod is activated, the cutting frame can be controlled to move the cutting blade, thereby cutting the brush filaments that have been collected.

[0009] Preferably, two sets of fixed clamps are symmetrically arranged on the mounting frame. The movable telescopic structure includes a third electric push rod. A fixed frame is provided on the fixed clamp near the cutting blade. The third electric push rod is set on the fixed frame. The moving block is set at the output end of the third electric push rod. Activating the third electric push rod controls the movement of the moving block, thereby controlling the movement of the second electric push rod to drive the cutting frame and the hot press plate. This allows for convenient hot pressing of the cutting end of the bristles, forming a protrusion at the cutting end. After being fixed in the clamping frame, this prevents the bristles from unwinding during winding and improves the winding stability of the bristles.

[0010] Preferably, the surface of the hot press plate, the side of the fixed clamping plate, and the side of the movable clamping plate are provided with an anti-stick coating. The anti-stick coating can prevent the bristles from sticking together after being hot-pressed by the hot press plate, thereby improving the smoothness of separation between the hot press plate, the fixed clamping plate, the movable clamping plate, and the bristles.

[0011] Preferably, the drive assembly includes a motor mounted on the take-up frame, with the back of the take-up shaft extending to the back of the take-up frame. Both the extended end of the take-up shaft and the output end of the motor are equipped with drive wheels. A drive belt is provided between two cooperating drive wheels. Starting the motor controls the rotation of the corresponding drive wheel. The cooperation between the drive wheel and the drive belt controls the cooperating drive wheel to rotate the take-up shaft, thereby achieving the rotation drive of the take-up wheel and thus realizing the take-up operation of the brush filaments. Here, the cooperation between the drive wheel and the drive belt can be a sprocket and chain belt, or a synchronous pulley and synchronous belt gear meshing transmission.

[0012] Preferably, both the fixed clamp and the movable clamp are provided with anti-slip protrusions on their surfaces, and the upper and lower anti-slip protrusions mesh with each other. The anti-slip protrusions can further improve the stability of the fixed clamp and the movable clamp when they clamp and fix the brush bristles. The meshing structure can achieve the clamping and holding of the brush bristles between the fixed clamp and the movable clamp, avoiding the brush bristles from coming off during movement and improving the stability of the bristle winding process.

[0013] Compared with known public technologies, the technical solution provided by this utility model has the following beneficial effects: 1. This utility model features two sets of staggered take-up shafts and take-up wheels, allowing seamless switching as one set of take-up wheels immediately takes over after the other set finishes taking up the wire. Traditional devices require stopping the machine to replace the take-up wheels, while this utility model, through its dual-station design, significantly reduces downtime during unloading and loading, improving the overall efficiency of brush filament processing. Furthermore, the automated switching mechanism further reduces the frequency of manual intervention, making it suitable for continuous production needs.

[0014] 2. This utility model, through the coordinated action of an XYZ three-axis drive platform, a fixed clamping plate, a moving clamping plate, and a vision tracking camera, can accurately capture the position of the bristles and automatically complete clamping, cutting, and hot-pressing fixation. The hot-pressing plate heat-presses the tail end of the bristles into a protrusion, which, together with the clamping frame on the take-up wheel, achieves a firm fixation, avoiding the tediousness and instability of traditional manual winding, and preventing loosening and detachment of bristles during the take-up process. This design not only reduces labor intensity but also ensures the standardization and consistency of the bristle feeding process.

[0015] 3. In this utility model, the hot-pressing plate forms anti-detachment protrusions at the tail end of the brush bristles. Combined with the mechanical fixation of the clamping frame, this provides double protection for the connection strength between the brush bristles and the take-up wheel. The anti-slip protrusions on the surfaces of the fixed clamping plate and the moving clamping plate further improve the clamping stability and prevent the brush bristles from sliding or loosening during the feeding and winding process. In addition, the anti-stick coating design avoids hot-pressing adhesion and ensures smooth separation of the components, thereby improving the reliability and long-term performance of the device.

[0016] 4. This utility model, in conjunction with a movable guide wheel, can provide uniform guidance during the brush bristle winding process, so that the brush bristles are evenly wound on the winding wheel, thereby improving the winding effect. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The above-mentioned wire taking-up device for brush filament processing includes a wire taking-up frame 1. Two wire taking-up shafts 2 are staggered vertically on the wire taking-up frame 1 via bearings, and a drive assembly is provided in cooperation with the wire taking-up shafts 2. A wire taking-up wheel 3 is installed on the wire taking-up shaft 2. A mounting frame 4 is provided at the feeding end of the wire taking-up frame 1 via an XYZ three-axis drive platform. A fixed clamping plate 5 is provided on the side of the mounting frame 4 near the wire taking-up wheel 3. A movable clamping plate 6 is provided at the bottom end of the fixed clamping plate 5. A first electric push rod 7 is provided on the fixed clamping plate 5 in cooperation with the movable clamping plate 6. A cutting frame 8 is provided on the side of the fixed clamping plate 5 near the wire taking-up wheel 3 in the XY direction. A cutting blade 9 is provided at the bottom end of the cutting frame 8. A hot pressing plate 10 is provided on the side of the cutting frame 8 near the fixed clamping plate 5. The hot pressing plate 10 is preferably electrically heated. A guide wheel 11 is movable and adjustable on the feeding end side of the mounting frame 4. A clamping frame 12 is provided on the wire taking wheel 3.

[0022] Please see Figures 1-6 As one implementation of the guide wheel 11: a guide frame 13 is provided on the take-up frame 1, a ball screw 14 is provided on the guide frame 13, and a screw nut 15 and a screw motor 16 are provided in conjunction with the ball screw 14. The guide wheel 11 is set on the screw nut 15 through a bracket structure. When the screw motor 16 is started, the ball screw 14 is controlled to reciprocate, so that the screw nut 15 can carry the guide wheel 11 to reciprocate relative to the take-up wheel 3, thereby achieving uniform winding of the brush filaments when they are taken up on the take-up wheel 3.

[0023] Please see Figures 1-6 As one implementation of the mounting frame 4: the mounting frame 4 is equipped with a vision tracking camera 17, which can locate the position of the brush filaments during cutting, thereby enabling more precise clamping and fixing of the brush filaments and subsequent cutting operations.

[0024] Please see Figures 1-6As one embodiment of the cutting frame 8: a second electric push rod 18 is provided at the top of the cutting frame 8, a moving block 19 is provided on the second electric push rod 18, and a movable telescopic structure is provided between the moving block 19 and the fixed clamping plate 5. When the second electric push rod 18 is activated, the cutting frame 8 can be controlled to move the cutting blade 9, thereby cutting the brush filaments that have been collected.

[0025] Please see Figures 1-6 As one embodiment of the fixed clamping plate 5: two sets of fixed clamping plates 5 are symmetrically arranged on the mounting frame 4. The movable telescopic structure includes a third electric push rod 20. A fixed frame 21 is provided on the fixed clamping plate 5 near the cutting blade 9. The third electric push rod 20 is set on the fixed frame 21. The moving block 19 is set at the output end of the third electric push rod 20. When the third electric push rod 20 is activated, the movement of the moving block 19 can be controlled by the third electric push rod 20, thereby controlling the movement of the second electric push rod 18 to drive the cutting frame 8 and the hot press plate 10. This allows for convenient hot pressing of the cutting end of the brush bristles, forming a protrusion at the cutting end. This prevents the brush bristles from unwinding after being fixed in the clamping frame 12, thus improving the stability of the brush bristle winding.

[0026] Please see Figures 1-6 As one embodiment of the hot press plate 10: the surface of the hot press plate 10, the side of the fixed clamping plate 5 and the side of the movable clamping plate 6 are provided with an anti-stick coating. The anti-stick coating can prevent the bristles from sticking together after being hot-pressed by the hot press plate 10, thereby improving the smoothness of separation between the hot press plate 10, the fixed clamping plate 5 and the movable clamping plate 6 and the bristles.

[0027] Please see Figures 1-6 As one implementation of the drive assembly: the drive assembly includes a motor 22, which is mounted on the take-up frame 1, and the back of the take-up shaft 2 extends to the back of the take-up frame 1. Both the extended end of the take-up shaft 2 and the output end of the motor 22 are provided with drive wheels 23. A drive belt 24 is provided between the two cooperating drive wheels 23. When the motor 22 is started, the corresponding drive wheel 23 is controlled to rotate. Through the cooperation of the drive wheel 23 and the drive belt 24, the cooperating drive wheel 23 can drive the take-up shaft 2 to rotate, thereby realizing the rotation drive of the take-up wheel 3, and thus realizing the take-up operation of the brush filaments. Here, the cooperation between the drive wheel 23 and the drive belt 24 can be the cooperation between a sprocket and a chain belt, or the gear meshing transmission between a synchronous pulley and a synchronous belt.

[0028] Please see Figures 1-6As one embodiment of the fixed clamping plate 5 and the movable clamping plate 6: both the fixed clamping plate 5 and the movable clamping plate 6 are provided with anti-slip protrusions 25, and the upper and lower anti-slip protrusions 25 mesh with each other. The setting of anti-slip protrusions can further improve the stability of the fixed clamping plate 5 and the movable clamping plate 6 when clamping and fixing the brush bristles. The meshing structure can realize the brush bristles biting and clamping between the fixed clamping plate 5 and the movable clamping plate 6, avoiding the situation of the brush bristles coming off during the movement, and improving the stability of the bristle winding process.

[0029] The complete working principle and steps of the above embodiments are as follows: This utility model sets two sets of take-up shafts 2, which are staggered vertically. In this way, after one set of take-up wheels 3 has finished taking up the wire, another set of take-up wheels 3 can be used to take up the wire during the unloading process, thereby reducing downtime and improving the wire taking up efficiency of the brush. This utility model is equipped with a fixed clamping plate 5, a movable clamping plate 6 and a cutting blade 9 in conjunction with the take-up wheel 3. In this way, when a set of take-up wheels 3 has finished taking up the wire and stopped working, under the positioning function of the visual positioning camera, the movable clamping plate 6 can be controlled to move to the lower part of the corresponding brush wire, while the fixed clamping plate 5 is positioned above the brush wire. Then, the first electric push rod 7 is controlled to move, causing the moving clamping plate 6 to move upward, thereby cooperating with the fixed clamping plate 5 to clamp and fix the brush filaments; Then, the second electric push rod 18 is activated. The second electric push rod 18 can control the cutting frame 8 to move the cutting blade 9, thereby cutting the brush filaments that have been collected. At the same time, the hot press plate 10 is preheated, and then the third electric push rod 20 is controlled to retract, so that the cutting frame 8 carries the hot press plate 10 to move towards the fixed clamping plate 5 and the moving clamping plate 6, so as to hot press the brush bristle tail end located outside the fixed clamping plate 5 and the moving clamping plate 6, so that the brush bristle tail end is deformed by heat to form a protrusion. Then, the mounting frame 4 is controlled by the XYZ three-axis drive platform to move the fixed clamping plate 5 and the moving clamping plate 6, thereby carrying the brush bristles to the top of the corresponding take-up wheel 3. Then, the brush bristles are controlled to descend so that the brush bristle segments between the two sets of fixed clamping plates 5 are positioned at the clamping frame 12 on the take-up wheel 3. The brush bristles are then controlled to descend so that they come into contact with the surface of the take-up wheel 3 and move into the clamping groove formed by the opening end of the clamping frame 12 and the surface of the take-up wheel 3. Thus, the brush bristles are clamped and fixed on the surface of the take-up wheel 3 by the clamping frame 12, thereby achieving automatic brush bristle feeding during the brush bristle feeding process and reducing the need for manual brush bristle feeding. Furthermore, this utility model uses a hot press plate 10 to perform hot pressing, so that the protrusion formed by hot pressing is located at the outer end of the winding of the clamping frame 12. In this way, the brush filaments can be further prevented from detaching from the clamping frame 12, thus improving the winding stability. After the above actions are completed, the control mounting frame 4 drives the fixed clamping plate 5, the moving clamping plate 6 and other components to detach from the winding wheel 3, waiting for the next round of operation. The XYZ three-axis drive platform described in this utility model is a known existing mobile drive structure, and will not be described in detail here. The assembly sequence between the components has been described in detail in this utility model. The components can be driven by a controller, which is a known prior art and will not be described in detail here. The feed end of the guide wheel of this utility model is connected to the tensioning wheel group of the brush filaments during the conveying process, which is used to realize the conveying and tensioning of the brush filaments during the winding process. This is a known structure and will not be described in detail in this utility model.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
