Description

Technical Field

[0001] This invention relates to the field of cotton swab processing equipment technology, and more specifically, to a cotton swab processing device for removing stray hairs. Background Technology

[0002] Cotton swabs are widely used hygiene products in medical, cosmetic, and cleaning fields, with huge demand every year. Their quality directly affects the safety and comfort of use. Therefore, multiple aspects of their processing need to be controlled.

[0003] The invention patent with publication number CN116831817A discloses an automatic production equipment for medical cotton swabs. It describes that the equipment includes a processing box, a feeding frame at one end of the processing box, and a cotton swab wooden rod stored inside the feeding frame. A conveyor belt is provided at the other end of the processing box, with one end of the conveyor belt extending into the processing box. A reinforcement component and a detection component are provided above the conveyor belt away from the processing box. With the reinforcement component, after the cotton swabs are processed, they continue to be transported by the conveyor belt towards the recycling box. At this time, the reinforcement component reinforces the cotton balls at both ends of the cotton swab, making the cotton balls fit the cotton swab wooden rod better. At the same time, the detection component detects whether the cotton balls at both ends of the cotton swab are reinforced in place after reinforcement, thereby ensuring the quality of the cotton swabs.

[0004] In actual use, the cotton swabs mentioned above will have some loose fibers at the head. These loose cotton fibers (loose fibers) have a high residual rate, which affects the cleanliness of the product and the safety during use. In addition, the wooden shaft at the tail of some cotton swabs may have burrs, which will lead to poor comfort during use.

[0005] Based on this, the present invention discloses a cotton swab processing device for removing stray hairs. Summary of the Invention

[0006] To address the issues raised in the background art, such as the presence of loose cotton fibers (hair) at the head of cotton swabs, which have a high residual rate affecting product cleanliness and safety during use, and the presence of burrs on the wooden shaft of some cotton swabs leading to poor comfort during use, this invention provides a cotton swab processing device for removing hair.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Therefore, the present invention provides a cotton swab processing device for removing stray hairs, see [link to relevant documentation]. Figure 1 - Figure 3 As shown, it includes a cotton swab processing device 1, a guide plate 2 installed on the cotton swab processing device 1, a hair removal box 3 installed at one end of the cotton swab processing device 1 near the guide plate 2, a hair removal chamber 4 opened inside the hair removal box 3, a hair removal device installed on one side inside the hair removal chamber 4, the hair removal device includes a first suction pipe 8 and a second suction pipe 19, a combing box 5 installed on the top of the hair removal box 3, a combing chamber 6 opened inside the combing box 5, a combing component installed in the combing chamber 6, a first collection box 7 installed at one end of the top of the combing box 5, a grinding component installed on the side of the hair removal chamber 4 away from the hair removal device, and a transfer port 33 opened through both ends of the hair removal box 3. The cotton swabs are manufactured and shaped on the cotton swab processing device 1 and transported one by one to the working range of the guide plate 2. Under the guidance of the guide plate 2, the cotton swabs are neatly arranged and enter the working range of the lint removal box 3. The lint removal operation is carried out inside the lint removal chamber 4. With the cooperation of the combing component inside the combing chamber 6 and the grinding component in the lint removal chamber 4, the lint removal effect of the cotton swabs is achieved, ensuring the quality of the cotton swabs.

[0030] A first suction pipe 8 is installed on one side of the opening space inside the hair removal chamber 4. An air suction nozzle is fixed to the bottom of the first suction pipe 8. A second suction pipe 19 is installed inside the hair removal chamber 4 away from the first suction pipe 8. An air suction nozzle is fixed to the bottom of the second suction pipe 19. The center lines of the first suction pipe 8 and the first connecting hose 9 are on the same horizontal line, and the working range of the air suction nozzle covers the movement trajectory of the cotton swab head. A first connecting hose 9 is installed on the first suction pipe 8. The end of the first connecting hose 9 is connected to one end of the combing box 5. An air pump 10 is installed on the first connecting hose 9. A second collection box 21 is set at the top of the hair removal box 3 away from the combing box 5. A second connecting hose 20 is installed on the second suction pipe 19. The end of the second connecting hose 20 is connected to the second collection box 21. A fan 22 is installed on the top of the second collection box 21. The suction nozzle adopts a conical flared structure, which can increase the fiber passing speed and avoid lint accumulation on the tube wall. When removing impurities from the cotton swab, the air pump 10 is used to set the first suction tube 8 to negative pressure mode, mainly capturing longer free impurities. The fan 22 is used to set the second suction tube 19 to high-pressure pulse mode, specifically adsorbing shorter fibers. A gradient negative pressure field is constructed through the first suction tube 8 and the second suction tube 19 to achieve dual-stage pressure control and realize the classification and capture of impurities of different sizes.

[0031] During operation, when the cotton swab enters the working range of the hair removal device inside the hair removal chamber 4, the suction nozzle at the bottom of the first suction pipe 8 generates suction, drawing the free cotton fibers from the swab head into the first suction pipe 8. The cotton fibers then enter the combing box 5 through the first connecting hose 9. Some cotton fibers adhering to the swab head enter the working range of the second suction pipe 19. The free ends of the cotton fibers at the bottom of the second suction pipe 19 are sucked up and placed vertically. Under the cutting effect of the cutting blade 25 in the grinding component, the vertical cotton fibers are cut off. These cut cotton fibers are drawn into the second suction pipe 19 and then collected into the second collection box 21 through the second connecting hose 20, achieving a multi-stage hair separation effect, enabling the classification and capture of hair of different sizes, and improving the accuracy of hair sorting.

[0032] For details, see Figure 4 - Figure 7As shown, the combing assembly includes a barrier net 11. The barrier net 11 is fixed to one end of the combing cavity 6 near the first connecting hose 9. A vertical first transmission belt 12 is installed inside the combing cavity 6. Rolling brushes 13 are equidistantly installed on the outer structural surface of the first transmission belt 12. The movement trajectory of the rolling brushes 13 contacts the net body of the barrier net 11. A through hole is opened through the top of the combing cavity 6. The combing cavity 6 is connected to the collection cavity inside the first collection box 7 through the through hole. A vertical second transmission belt 14 is installed inside the combing cavity 6 near the first transmission belt 12. Scraping comb teeth 15 are equidistantly installed on the outer structural surface of the second transmission belt 14. The top of the scraping comb teeth 15 passes through the through hole and is inserted into the collection cavity of the first collection box 7. The movement trajectory of the scraping comb teeth 15 does not contact the inner wall of the opening of the through hole. The movement trajectory of the scraping comb teeth 15 intersects with the movement trajectory of the rolling brushes 13. The rolling brush 13 on the first transmission belt 12 and the scraping comb 15 on the second transmission belt 14 move in opposite directions. The rolling brush 13 moves at a certain linear speed to collect loose cotton fiber bundles, while the scraping comb 15 moves at a lower speed than the rolling brush 13 to peel off the cotton fibers and guide them to the collecting comb 16. The differential speed movement between the scraping comb 15 and the rolling brush 13 can reduce the shearing force on the main fibers and ensure the quality of the collected cotton fibers for subsequent reuse. The barrier net 11 is coated with PTFE and, together with the periodic scraping of the rolling brush 13, achieves zero-residue operation.

[0033] A flip-up plate 18 is installed on the outer side of the end of the first collection box 7 away from the first connecting hose 9. Collection combs 16 are fixed at equal intervals on the vertical inner wall of the flip-up plate 18 near the connecting hole. The rotation trajectory of the scraping comb 15 intersects with the working position of the collection comb 16. The intersection angle between the collection comb 16 and the scraping comb 15 is 45 degrees, ensuring that the stripped cotton fibers can fall into the interior of the depilatory chamber 4. After a certain amount of cotton fibers are collected inside the first collection box 7, the cotton fibers can be removed by flipping the flip-up plate 18, which facilitates the subsequent cleaning of the interior of the first collection box 7.

[0034] A drive assembly 17 is installed on the vertical surface of the combing box 5 and the first collection box 7 on the same side. The drive assembly 17 can drive the movement of the first transmission belt 12 and the second transmission belt 14. The width of the first transmission belt 12 is the same as the width of the second transmission belt 14. The differential speed between the rolling brush 13 and the scraping comb 15 can be adjusted by the drive assembly 17 to accommodate cotton swabs of different sizes.

[0035] A small motor 23 is installed at an eccentric position on the top of the hair removal box 3. The output shaft of the small motor 23 is inserted into the hair removal chamber 4 and a rotating shaft 24 is installed thereon. A cutting blade 25 is installed at the bottom of the rotating shaft 24. The horizontal height of the cutting blade 25 is lower than the horizontal height of the bottom suction nozzle of the second suction pipe 19. The working position of the cutting blade 25 is tangent to the top of the movement trajectory of the cotton swab head. When cotton fibers that cannot be removed stick to the cotton swab head, in order to ensure that the shape and fluffiness of the cotton fibers are not affected, the small motor 23 can be started. The operation of the small motor 23 drives the rotating shaft 24 and the cutting blade 25 to rotate. The cotton fibers pulled by the negative pressure of the bottom suction nozzle of the second suction pipe 19 will be cut along the surface of the cotton swab. The cut cotton fibers will then be collected into the second suction pipe 19 to ensure the cleanliness of the cotton swab head.

[0036] During operation, when the cotton swab enters the working range of the first suction pipe 8, the suction nozzle at the bottom of the first suction pipe 8 extracts the free cotton fibers and blows them into the combing chamber 6 of the combing box 5. The blown-in cotton fibers will wrap around the barrier net 11. The drive assembly 17 is activated, and the first transmission belt 12 drives the rolling brush 13 to move at a moving speed. At the same time, the second transmission belt 14 drives the scraping comb 15 to move at a speed lower than that of the first transmission belt 12. The rolling brush 13 scrapes and collects the cotton fibers on the barrier net 11. In the differential speed movement with the scraping comb 15, the cotton fibers on it will be peeled off and guided by the scraping comb 15 to the collecting comb 16. Finally, they are collected inside the first collection box 7. The differential speed design reduces the shearing force on the main fibers, reduces the damage rate of cotton fibers, and improves the cotton fiber recovery rate.

[0037] Further, see Figure 1 , Figure 8 As shown, the grinding assembly includes a drive motor 28. The drive motor 28 is installed on the outside of the side plate of the depilatory box 3 away from the second exhaust pipe 19. The output shaft end of the drive motor 28 is inserted into the interior of the depilatory chamber 4 and a grinding head 29 is installed thereon. An exhaust port 30 is opened on the bottom end face of the inner wall of the depilatory chamber 4, located directly below the grinding head 29. A collection hopper is fixed to the bottom end face of the depilatory box 3 at the opening of the exhaust port 30. A receiving box 31 is installed on the depilatory box 3 near the exhaust port 30. A connecting pipe is installed on the receiving box 31, and the top end of the connecting pipe is connected to the collection hopper at the bottom of the exhaust port 30. Some cotton swabs may have burrs at the end of the swab. When the cotton swab enters the working range of the grinding component, the drive motor 28 operates and the grinding head 29 rotates to grind the end of the cotton swab, so as to avoid the burrs affecting the comfort of use. At the same time, the debris generated during grinding will enter the interior of the receiving box 31 through the air extraction port 30 to prevent the cotton swab from being contaminated again during the process of removing impurities.

[0038] Fixed shafts 26 are equidistantly fixed to the inner wall of the depilatory chamber 4 near the grinding head 29. A rotating pressure roller 27 is rotatably sleeved on the outer end of the fixed shaft 26 near the first suction pipe 8. A partition 32 is fixed to the inner wall of the depilatory chamber 4. The partition 32 is sleeved on the outer side of the fixed shaft 26 and close to the rotating pressure roller 27. The bottom end face of the partition 32 and the top end face of the transfer port 33 are on the same horizontal plane. The partition 32 can separate the working space of the grinding component and the depilatory device to avoid interference and ensure the cleanliness of the recovered cotton fibers. After the cotton swab enters the depilatory chamber 4 through the transfer port 33, the rotating pressure roller 27, in cooperation with the fixed shaft 26, rotates in conjunction with the cotton swab processing device 1 to press the cotton swab tightly into the structural groove of the cotton swab processing device 1, preventing the cotton swab from falling out of the structural groove of the cotton swab processing device 1 under the action of suction, and ensuring the smooth operation of the depilatory device and the grinding component.

[0039] During operation, after the cotton swab enters the depilatory chamber 4 through the transfer port 33, it immediately enters the working range of the rotating pressure roller 27. As the cotton swab processing device 1 continuously feeds the cotton swab, the rotating pressure roller 27 rotates in coordination with the cotton swab processing device 1, so that the cotton swab is always tightly pressed in the structural groove in the cotton swab processing device 1. After the cotton swab enters the working range of the grinding component, the drive motor 28 drives the grinding head 29 to rotate and grind the end of the cotton swab. At the same time, the debris generated during grinding will enter the receiving box 31 through the air extraction port 30. Under the spatial separation effect of the partition 32, secondary contamination of the cotton swab is avoided, and the cleanliness of the recycled cotton fibers is guaranteed.

[0040] In summary, this effectively solves the problem of some loose cotton fibers (hair) remaining at the head of the cotton swab, which affects the cleanliness of the product and the safety during use. In addition, some cotton swabs have burrs on the wooden shaft at the tail, which leads to poor comfort during use.

[0041] Working principle: When removing hair from cotton swabs, the cotton swab processing device 1 transports the formed cotton swabs one by one to the working range of the guide plate 2. Under the guidance of the guide plate 2, the cotton swabs will move neatly into the working range of the hair removal box 3 and enter the hair removal chamber 4 through the transfer port 33. As the cotton swab processing device 1 continues to feed the cotton swabs, the rotating pressure roller 27 contacts the cotton swabs and rotates in coordination with the transport of the cotton swab processing device 1, which can press the cotton swabs tightly into the structural groove of the cotton swab processing device 1.

[0042] When the cotton swab enters the working range of the first suction pipe 8 along with the cotton swab processing device 1, the suction nozzle at the bottom of the first suction pipe 8 generates suction, which draws the cotton fibers in the free state of the cotton swab head into the first suction pipe 8. The cotton fibers enter the combing chamber 6 of the combing box 5 through the first connecting hose 9, and then wrap around the barrier net 11. The drive assembly 17 is activated, and the first transmission belt 12 drives the rolling brush 13 to move at a moving speed. At the same time, the second transmission belt 14 drives the scraping comb 15 to move at a speed lower than that of the first transmission belt 12. The rolling brush 13 scrapes and collects the cotton fibers on the barrier net 11. In the differential speed movement with the scraping comb 15, the cotton fibers on it will be guided by the glass and the scraping comb 15 to the collecting comb 16, and finally collected inside the first collection box 7. The differential speed design reduces the shearing force on the main fibers, reduces the damage rate of cotton fibers, and improves the cotton fiber recovery rate.

[0043] Some cotton fibers adhering to the head of the cotton swab will enter the working range of the second suction pipe 19. The free ends of the cotton fibers at the bottom of the second suction pipe 19 will be sucked up and placed in a vertical position. Under the cutting effect of the cutting blade 25 in the grinding component, the vertical cotton fibers will be cut off. These cut cotton fibers will be drawn into the second suction pipe 19 and then collected into the second collection box 21 through the second connecting hose 20, realizing the multi-stage hair separation effect and improving the hair sorting accuracy.

[0044] Finally, after the cotton swab enters the working range of the grinding component, the drive motor 28 drives the grinding head 29 to rotate and grind the end of the cotton swab. At the same time, the grinding debris will enter the interior of the receiving box 31 through the air extraction port 30. Under the spatial separation effect of the partition 32, secondary contamination of the cotton swab is avoided.
