Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of brush processing, and more specifically, to a brush brush deburring device. Background Technology

[0002] In the brush manufacturing process, after the brushes are formed (such as toothbrushes, cleaning brushes, and industrial brushes), the front bristles need to be de-brittled to remove short, stray hairs and impurities left after trimming, ensuring the neatness and cleanliness of the bristles. This process directly affects the user experience and product competitiveness. As specialized processing equipment, the de-brittle removal device for brush processing directly determines processing efficiency and brush quality through its ability to collect loose hairs and its continuous processing. As brush products become more refined and aesthetically pleasing, the shortcomings of traditional de-brittle removal methods are becoming increasingly apparent: existing de-brittle removal devices are generally inconvenient for collecting fallen hairs, and the processing methods are inconsistent, causing not only hair contamination but also extending the production cycle, making it difficult to meet the demands for efficient and clean processing.

[0003] Traditional methods for removing lint often involve manual handheld blowers or simple brushes. Lint is easily blown into the workshop air or accumulates on the workbench, polluting the work environment and requiring extra time for cleaning. Furthermore, the scattered lint may re-adhere to the brush surface, affecting the removal efficiency. At the same time, existing devices are mostly single-function structures, requiring manual transfer of the brush to the next process (such as quality inspection or packaging) after lint removal. This makes it impossible to achieve a continuous operation of lint removal, collection, and transfer, requiring frequent manual intervention in intermediate steps, which disrupts the processing rhythm. The problem of low efficiency is particularly prominent in mass production.

[0004] Therefore, developing a brush-removal device with efficient hair collection capabilities and continuous processing is an urgent need to improve brush quality and production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a brush brush processing device for removing broken hairs, which solves the technical problems that existing brush brush processing devices are generally inconvenient to collect fallen broken hairs and have inconsistent processing methods.

[0006] According to one aspect, at least one embodiment of this disclosure provides a brush-processing hair removal device, comprising: The equipment frame and the material conveyor belt are mounted on the equipment frame; Several bosses and a feeding conveyor assembly are provided. The bosses are evenly distributed around the side surface of the material conveyor belt. The feeding conveyor assembly is mounted on the equipment frame. The feeding conveyor assembly is mounted on the material conveyor belt and the equipment frame. The outer casing and the lint assembly are provided, with the outer casing fixed to the outside of the equipment frame and the lint assembly disposed inside the outer casing. The shredding assembly includes a transmission port, which is opened on the outer box along the conveying direction of the material conveyor belt. A transmission frame is provided on the side surface of the outer box, one end of which is located inside the outer box. A shredding blade holder is vertically rotatably connected to one end of the transmission frame located inside the outer box.

[0007] As a further technical solution, a rotating wheel driven by electricity is provided at the other end of the transmission frame, and a driven wheel is provided at the lower end of the crushing blade holder. The rotating wheel and the driven wheel are connected by belt drive, and the crushing blade holder is located at the transmission port.

[0008] As a further technical solution, both sides of the outer casing are horizontally linearly connected with baffles, the baffles having an L-shaped structure and being attached to the outside and top of the outer casing, and a material conveyor belt is provided on the outside of the equipment frame.

[0009] As a further technical solution, a bracket is provided on the top of the equipment frame, and a telescopic cylinder is installed vertically downward on the top of the bracket. A push-out block is provided at the output end of the telescopic cylinder, and the telescopic cylinder is located above the feeding conveyor belt.

[0010] According to another aspect, in at least one embodiment of the present invention, the feeding and conveying assembly includes a plurality of docking slots, all of which are formed on the surface of the boss. A rectangular sleeve is inserted into the docking slot, and the rectangular sleeve is fixedly connected to the docking slot by bolts.

[0011] As a further technical solution, a pair of horizontal bars are fixedly connected inside the rectangular sleeve. Clamping sleeves are slidably fitted at both ends of the horizontal bars. Springs are fitted at both ends of the horizontal bars. The clamping sleeves are in the shape of a horizontal U-shape. Inclined plates are provided at both the upper and lower ends of the clamping sleeves.

[0012] As a further technical solution, a support platform is provided around the outer surface of the equipment frame, and the support platform slides against the lower end face of the material conveyor belt.

[0013] As a further technical solution, the bottom of the outer box is an inclined surface, and one side of the bottom of the outer box is an open structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the lint removal assembly solves the problems of scattered lint and discontinuous processing in traditional devices through a closed lint removal and continuous transfer design. The shredder rotates at high speed inside the closed outer box, accurately removing lint from the brush end face. An L-shaped baffle prevents lint from overflowing, and an inclined bottom guides the lint to be discharged in a concentrated manner, avoiding environmental pollution. The feeding conveyor belt and the ejector block work together to automatically transfer the brush after lint removal, eliminating the need for manual transfer and realizing the lint removal operation.

[0015] The belt drive between the rotating and driven wheels ensures stable hair removal force, and the transmission port is adapted to the conveyor belt's conveying direction to guarantee precise brush alignment. This structure not only improves the efficiency and cleanliness of hair removal but also eliminates manual intervention in the processing stage, significantly shortening the production cycle and meeting the needs of mass production of brushes.

[0024] like Figures 1-4 As shown, it illustrates a brush-processing lint removal device according to an embodiment of the present disclosure, comprising: The equipment frame 1 and the material conveyor belt 2 are mounted on the equipment frame 1. Several bosses 3 and a feeding conveyor assembly 6 are provided. The bosses 3 are evenly arranged around the side surface of the material conveyor belt 2. The feeding conveyor assembly 6 is arranged on the equipment frame 1. The feeding conveyor assembly 6 is arranged on the material conveyor belt 2 and the equipment frame 1. The outer box 4 and the lint assembly 5 are fixed to the outside of the equipment frame 1, and the lint assembly 5 is disposed in the outer box 4. The shredding assembly 5 includes a transmission port 5-1, which is located on the outer casing 4 along the conveying direction of the conveyor belt 2. A transmission frame 5-2 is provided on the side surface of the outer casing 4. One end of the transmission frame 5-2 is located inside the outer casing 4, and a shredder holder 5-3 is vertically rotatably connected to one end of the transmission frame 5-2 inside the outer casing 4. A electrically driven rotating wheel 5-4 is provided inside the other end of the transmission frame 5-2. A driven wheel 5-5 is provided at the lower end of the shredder holder 5-3. The rotating wheel 5-4 and the driven wheel 5-5 are connected by a belt. The crushing blade holder 5-3 is located at the transmission port 5-1. Both sides of the outer casing 4 are horizontally linearly driven connected with baffles 5-6. The baffles 5-6 have an L-shaped structure and are attached to the outside and top of the outer casing 4. The outer side of the equipment frame 1 is provided with a feeding conveyor belt 5-7. The top of the equipment frame 1 is provided with a bracket 5-8. The top of the bracket 5-8 is vertically downwardly mounted with a telescopic cylinder 5-9. The output end of the telescopic cylinder 5-9 is provided with a push-out block 5-10. The telescopic cylinder 5-9 is located above the feeding conveyor belt 5-7.

[0025] In some examples, to achieve thorough removal and centralized collection of loose hairs from the downward-moving brush end face and prevent loose hairs from scattering and contaminating the equipment or environment, a loose hair assembly 5 is designed. This assembly includes a transmission port 5-1 on the outer casing 4 along the conveying direction of the conveyor belt 2, providing a channel for the brush end face to enter the outer casing 4 for hair removal. This ensures that when the brush moves with the conveyor belt, the end face to be removed can accurately extend into the outer casing 4 and contact the crushing blade holder 5-3, avoiding deviation that would lead to incomplete hair removal. The transmission frame 5-2 on the side surface of the outer casing 4 provides mounting support for the crushing blade holder 5-3 and the rotating wheel 5-4. One end of the transmission frame 5-2 is located inside the outer casing 4 and is vertically rotatably connected to the crushing blade holder 5-3. The other end is electrically driven rotating wheel 5-4, which drives the driven wheel 5-5 at the lower end of the crushing blade holder 5-3 to rotate via a belt, thereby causing the crushing blade holder 5-3 to rotate at high speed. The blades on its surface can cut and comb the loose hairs from the brush end face, thoroughly removing the loose hairs. The L-shaped baffles 5-6 connected to the horizontal linear drive on both sides of the outer box 4 can be adjusted in position by linear drive. During the hair removal operation, the baffles 5-6 fit against the outside and top of the outer box 4 to form a closed hair removal space. This prevents the hair fragments generated by crushing from falling from the gaps in the outer box 4 or the transmission port 5-1, and also guides the hair fragments to fall into the bottom of the outer box 4 under the action of gravity (for easy subsequent centralized cleaning).

[0026] The feeding conveyor belt 5-7 on the outside of the equipment frame 1 is used to receive the brushes after hair removal. The telescopic cylinder 5-9 at the top of the bracket 5-8 drives the push block 5-10 to move downward, which can push the brushes that have been de-haired on the feeding conveyor belt 2 from the boss 3 to the feeding conveyor belt 5-7, so as to realize the smooth transfer of the brushes from the hair removal station to the next process and avoid the low efficiency caused by manual transfer. The belt drive between the rotating wheel 5-4 and the driven wheel 5-5 ensures the stable rotation speed of the crushing blade holder 5-3 and guarantees uniform hair removal force. The multi-faceted design of the L-shaped baffle plate 5-6 enhances the sealing and prevents the hair fragments from spilling out. The cooperation between the push-out block 5-10 and the feeding conveyor belt 5-7 realizes the automatic transfer of the brush and improves the continuity of the process.

[0027] During operation, the brush enters the outer casing 4 via the transmission port 5-1 on the material conveyor belt 2. The shredder 5-3 rotates to remove the bristles, and the baffle plate 5-6 closes to prevent scattering. After bristle removal, the push-out block 5-10 pushes the brush onto the unloading conveyor belt 5-7. Rotational bristle removal ensures thorough removal, and the baffle plate prevents contamination. All components work together to complete the removal and transfer of broken bristles, meeting the brush processing requirements.

[0028] like Figures 1-4 As shown in the figure, the feeding and conveying assembly 6 in this embodiment includes a plurality of docking slots 6-1. The docking slots 6-1 are all formed on the surface of the boss 3. A rectangular sleeve 6-2 is inserted into the docking slot 6-1. The rectangular sleeve 6-2 and the docking slot 6-1 are fixedly connected by bolts. A pair of crossbars 6-3 are horizontally fixedly connected inside the rectangular sleeve 6-2. Clamping sleeves 6-4 are slidably fitted at both ends of the crossbars 6-3. Springs 6-6 are fitted at both ends of the crossbars 6-3. The clamping sleeves 6-4 are generally U-shaped. Inclined plates 6-5 are provided at both the upper and lower ends of the clamping sleeves 6-4.

[0029] In some examples, in order to achieve stable clamping and synchronous conveying of brushes of different specifications, and to ensure that the brushes always keep the end face to be removed facing down when moving with the material conveyor belt 2, so as to complete precise hair removal in conjunction with the hair removal component 5, a feeding conveyor component 6 is designed. This component includes a docking groove 6-1 opened in the protrusion 3 on the side surface of the material conveyor belt 2, which provides an installation base for the rectangular sleeve 6-2. The rectangular sleeve 6-2 is fixed to the docking groove 6-1 by bolts, which facilitates the replacement of different specifications of sleeves according to the brush size in the future, thereby improving the adaptability of the device to multiple specifications of brushes.

[0030] A pair of horizontally fixed crossbars 6-3 inside the rectangular sleeve 6-2 provide sliding support for the clamping sleeves 6-4. The horizontal U-shaped clamping sleeves 6-4, which are slidably fitted at both ends of the crossbars 6-3, can clamp the brush through the elastic force of the spring 6-6. When the brush is placed between the two clamping sleeves 6-4, the spring 6-6 is compressed and generates a reverse elastic force, which pushes the clamping sleeves 6-4 to adhere to the brush surface from both sides, forming a stable clamping force and preventing the brush from loosening or shifting when moving with the conveyor belt or during hair removal. The inclined plates 6-5 at both ends of the clamping sleeve 6-4 serve as guides, making it easy for operators to quickly place the brush between the clamping sleeves 6-4, avoiding low feeding efficiency due to alignment difficulties. The elastic design of the spring 6-6 allows the clamping sleeve 6-4 to automatically adjust the spacing according to the brush diameter, adapting to brushes of different thicknesses, eliminating the need for frequent replacement of clamping components and reducing operational complexity.

[0031] The bolt fixing of the rectangular sleeve 6-2 to the boss 3 ensures that the sleeve does not loosen when it moves synchronously with the conveyor belt. The symmetrical distribution of the crossbars 6-3 makes the clamping sleeve 6-4 bear the force evenly, avoiding the deformation of the brush due to excessive force on one side.

[0032] During operation, the brush is placed between clamping sleeves 6-4, and spring 6-6 drives clamping sleeves 6-4 to clamp it. The brush moves with the conveyor belt 2 to the lint removal assembly 5 for lint removal. After lint removal, it continues to move with the conveyor belt to the ejection station. The elastic clamping is compatible with multiple specifications, and the synchronous movement ensures accurate lint removal. All components work together to stably transport the brush and meet the lint removal requirements of the lint removal assembly 5.

[0033] For example, such as Figure 1 As shown, a support platform 7 is provided around the outer surface of the equipment frame 1, and the support platform 7 slides against the lower end face of the material conveyor belt 2.

[0034] In some examples, the support platform 7, which is designed to slide against the lower end face of the conveyor belt 2 around the outer surface of the equipment frame 1, provides full-area support for the conveyor belt 2. Since the protrusion 3 carrying the brush on the conveyor belt 2 is prone to sagging due to gravity, the support platform 7 can apply upward support from the lower end face, preventing sagging in the middle or edge of the conveyor belt from causing brush position displacement and ensuring that the brush is always accurately aligned with the transmission port 5-1 of the outer casing 4 as the conveyor belt moves.

[0035] For example, such as Figure 3 As shown, the bottom of the outer box 4 is an inclined surface, and one side of the bottom of the outer box 4 is an open structure.

[0036] In some examples, the inclined structure at the bottom of the outer casing 4 and the opening on one side can efficiently guide the lint to be discharged in a concentrated manner. After the lint removed by the shredder 5-3 falls onto the inclined bottom surface, it will automatically slide along the inclined surface towards the opening under the action of gravity, eliminating the need for manual cleaning of the inside of the outer casing 4 and reducing maintenance costs.

[0037] In practical use: Select a suitable rectangular sleeve 6-2 according to the brush specifications, and fix it in the docking groove 6-1 of the boss 3 of the conveyor belt 2 with bolts. The spring 6-6 pushes the clamping sleeve 6-4 to slide along the crossbar 6-3 to form a clamping space suitable for the brush. Put the brush into the clamping sleeve 6-4, and the inclined plate 6-5 guides the brush to fit smoothly. The clamping sleeve 6-4 firmly clamps the brush under the action of the spring 6-6, ensuring that the end face to be de-haired is facing down. Start the conveyor belt 2 to move the brush towards the lint-breaking assembly 5. At the same time, the horizontal linear drive pushes the L-shaped baffle 5-6 to fit against the outer box 4, sealing the sides and top of the transmission port 5-1. The electrically driven rotating wheel 5-4 drives the crushing blade holder 5-3 to rotate through the belt. The brush enters the outer box 4 through the transmission port 5-1 with the conveyor belt. The crushing blade holder 5-3 removes the lint from the end face, and the lint is discharged from the opening along the inclined bottom surface of the outer box 4. After the hair removal is completed, the brush moves with the conveyor belt to the top of the unloading conveyor belt 5-7. The telescopic cylinder 5-9 on the bracket 5-8 pushes the push-out block 5-10, pushing the brush from the clamping sleeve 6-4 to the unloading conveyor belt 5-7, and transferring it to the next process. The entire process realizes automatic brush feeding, hair removal and transfer without frequent manual intervention.
