Abstract
Description
Technical Field
[0001] This invention relates to the field of waste filament recycling technology, and in particular to a waste filament recycling and processing device for the textile industry. Background Technology
[0002] The core function of waste filament recycling and processing in the textile industry revolves around waste filaments (such as broken filaments, scraps, and waste fibers) generated in textile production. These waste filaments are essentially typical solid wastes in the textile industry and possess the properties of recyclable solid materials.
[0003] A search revealed CN114606604A, which proposes a "feeding device for recycling waste filaments in the textile industry." This device includes a recycling box and a feeding hopper. A support plate is fixed inside the recycling box, and a guide plate is fixed on the inner wall of the recycling box. The output end of the guide plate is located above the support plate. A pushing mechanism is provided on the upper surface of the support plate, and a cutting mechanism is provided at the output end of the pushing mechanism. The cutting mechanism includes a rotating roller and cutting blades evenly distributed on the surface of the rotating roller. The rotating roller is rotatably mounted on the side wall of the support plate, and a feeding mechanism is provided below the support plate. The cutting mechanism also includes a motor mounted on the side wall of the recycling box. A rotating shaft is connected to the output end of the motor and is rotatably mounted on the side wall of the support plate. The rotating shaft is coaxially fixed with the rotating roller. The rotating roller has a hollow structure, and its outer surface is evenly distributed with air holes communicating with its interior. By setting up an air collection box and an elastic airbag, high-speed airflow can be periodically ejected from the air holes. This high-speed airflow can blow off the waste filaments wrapped around the rotating roller and cutting blades, preventing the cutting blades from being affected by the entanglement of waste filaments.
[0004] The aforementioned device uses a single hollow chamber as the airflow channel for its rotating roller. When the airflow enters the roller through the connecting pipe, it diffuses randomly within the chamber due to the lack of effective airflow guidance and balanced pressure distribution. This random diffusion directly leads to significant differences in the air jet pressure at different positions along the roller's axial direction. Specifically, the air jet pressure is significantly higher near the connecting pipe due to the strong initial impact force and low loss of the airflow. However, in the roller's edge region far from the connecting pipe, the airflow pressure decreases significantly during transmission due to chamber space diffusion and resistance losses. Because of this large difference in axial air jet pressure, the waste wire blowing effect is poor in the area far from the connecting pipe, increasing the risk of waste wire entanglement at this location. While the pressure valve on the connecting pipe ensures sufficient airflow strength to blow away waste wire each time, it cannot change the problem of random airflow diffusion caused by the single hollow chamber of the roller, nor can it balance the pressure difference between the ends near and far from the connecting pipe.
[0005] According to the search, CN118480884B proposes "a waste filament recycling device for non-woven fabric processing". Through the linkage of crushing mechanism and washing mechanism, it can crush non-woven fabric in water. Moreover, while crushing the non-woven fabric, the violent shaking caused by the water flow can further finely crush the non-woven fabric, making the non-woven fabric crushed more uniformly.
[0006] The above-mentioned equipment crushes the components in water. While this method can assist in crushing and reduce the splashing of waste fibers, it has significant disadvantages compared to a standalone crushing method. The main issue is that underwater crushing places higher demands on the equipment's sealing and waterproofing. For example, the cylinders in the crushing mechanism and the motors in the screening mechanism require additional waterproofing treatment. This not only increases the equipment's manufacturing cost and maintenance difficulty but may also lead to component corrosion and circuit failure due to long-term water immersion, thus shortening the equipment's lifespan. Compared to a standalone crushing method, this method is more direct, efficient, and safer in terms of operation. Summary of the Invention
[0007] The purpose of this invention is to solve the problem in the prior art where the air pressure is significantly higher near the connecting pipe due to the strong initial impact force and low loss of the airflow, while the air pressure is greatly reduced in the edge area of the rotating roller far from the connecting pipe due to factors such as diffusion of the chamber space and resistance loss during the transmission process. Therefore, this invention proposes a waste filament recycling and processing device for the textile industry.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a waste filament recycling and processing device for the textile industry, comprising: a recycling box, a rotating roller, and a support plate. The support plate is fixedly connected to the interior of the recycling box. Both ends of the rotating roller are rotatably connected to the inner wall of the recycling box and the support plate, respectively. An air collection box is installed on the outer wall of the recycling box. A cutting blade is fixed to the outside of the rotating roller. Air holes communicating with the interior are evenly distributed on the outer surface of the rotating roller. An airflow balancing structure is installed inside the rotating roller. The interior of the rotating roller is hollow. The airflow balancing structure includes a guide cylinder fixed inside the rotating roller, and three airflow balancing structures equidistantly arranged outside the guide cylinder. The roller is divided into four independent sub-cavities by three partitions. The guide tube has four directional guide holes evenly distributed, each corresponding to one of the four independent sub-cavities. The center of the guide tube is connected to the gas collection box through a connecting pipe, and the guide tube rotates around the connecting pipe. The diameter of the four directional guide holes gradually increases from the end closer to the connecting pipe to the end farther away from the connecting pipe to compensate for the pressure loss of the airflow along the roller axis. The recovery box is equipped with an air pump, which is connected to the gas collection box through a pipeline. The inside of the guide tube is provided with four sets of equidistantly distributed dynamic pressure regulating structures to cooperate with the directional guide holes.
[0009] As a further embodiment of the present invention, the dynamic pressure regulating structure includes a support rod inside the guide tube, the support rod being provided with a first groove, a movable plate being slidably connected to the support rod along the first groove, a first spring being fixed inside the guide tube, and one end of the first spring being fixedly connected to the movable plate, a conical block being fixed to the movable plate, the conical block being located inside the directional guide hole, and the conical block including a thick end and a thin end.
[0010] As a further embodiment of the present invention, the air hole is provided with a sealing structure inside, which is used to prevent waste wire from entering the inside of the roller through the air hole when the equipment is not in operation.
[0011] As a further embodiment of the present invention, the sealing structure includes four thin sheets made of elastic material fixed to the inner wall of the vent, and the surface of the thin sheets is provided with guide wire grooves, the inside of the guide wire grooves is provided with blades, and the inside of the directional flow hole is provided with a spiral groove.
[0012] As a further embodiment of the present invention, the cutting blade is provided with a cooling structure inside, the cooling structure cooperates with the airflow in the independent sub-cavity, the inside of the cutting blade is a hollow groove, the hollow groove is connected to an air inlet, the air inlet extends into the inside of the independent sub-cavity, the side of the cutting blade is provided with an exhaust port, and the exhaust port is equipped with a one-way valve.
[0013] As a further embodiment of the present invention, the cooling structure further includes a metal conductive rod fixed to the cutting blade, one end of the metal conductive rod being located inside an independent sub-cavity, and the other end of the metal conductive rod extending into the interior of the hollow groove.
[0014] As a further embodiment of the present invention, the bottom of the recycling bin is provided with an impurity collection structure and a collection box. The impurity collection structure includes a second groove on the inner wall of the recycling bin, a slider is slidably connected to the second groove, a third spring is provided inside the second groove and connected to the bottom of the slider, the slider and the collection box are provided with insertion holes, and a pin is inserted into the insertion holes of the slider and the collection box, thereby realizing the installation and removal of the collection box.
[0015] As a further embodiment of the present invention, the impurity collection structure further includes an emergency box that can be pulled out at the bottom of the recycling box and located at the bottom of the collection box. The side wall of the emergency box is equipped with a plate-shaped magnet, and the bottom of the collection box is fixed with an iron plate. The magnet and the iron plate cooperate with each other.
[0016] As a further embodiment of the present invention, the impurity collection structure further includes a material discharge trough at the bottom of the collection box, a baffle rod fixed inside the material discharge trough, the baffle rod having a through hole, a top plate fixed at the bottom of the emergency box, the width of the top plate being smaller than the width of the through hole, a third groove provided on the inner wall of the collection box, and a lifting plate slidably connected along the third groove inside the collection box, the lifting plate initially being located inside the material discharge trough and in contact with the top of the baffle rod.
[0017] As a further embodiment of the present invention, the impurity collection structure is linked to a reminder component. The reminder component includes a recycling bin slidably connected to a reminder rod. A second spring is provided on the outside of the reminder rod. One end of the reminder rod is located inside the recycling bin and is fixed with a wedge block. The reminder rod has reminder stripes that gradually become darker from the end away from the wedge block to the end closer to the wedge block. The bottom of one end of the collection bin is provided with a bevel that cooperates with the wedge block.
[0018] The textile waste filament recycling and processing device proposed in this invention has the following advantages: 1. By setting up an airflow balancing structure and an air pump, gas can be replenished when the elastic airbag in the comparison document is unstable. This complements the elastic airbag in the first comparison document. When the air pressure in the air collection box reaches the critical value of the pressure valve on the connecting pipe, the gas in the air collection box is injected into the interior of the guide tube through the connecting pipe. Then, it enters the interior of the four independent sub-cavities through the directional guide holes. Since the diameter of the directional guide holes gradually increases from the end near the connecting pipe to the end away from the connecting pipe, it compensates for the pressure loss of the airflow along the axis of the rotating roller, so that the air pressure in each independent sub-cavity remains the same, thereby achieving airflow balancing. Each independent sub-cavity corresponds to two cutting blades, solving the problem of uneven airflow pressure along the axis of the rotating roller in the comparison document. This ensures that the waste wire blown off at each position outside the rotating roller has the same effect, preventing waste wire from wrapping around the rotating roller in positions with weak airflow.
[0019] 2. Through the dynamic pressure adjustment structure, under normal conditions (i.e., when there is no coarse waste wire entanglement), when the roller rotates at high speed, the centrifugal force pushes the movable plate to move outward against the tension of the No. 1 spring, causing the coarse end of the conical block to enter the air hole. In other words, when the centrifugal force of the roller is large, the coarse end of the conical block is located inside the air hole. However, when the cutting blade encounters coarse waste wire, the load on the roller increases, and the rotation speed decreases. The centrifugal force on the movable plate and the No. 1 spring decreases, and the No. 1 spring retracts partially and pulls the movable plate and the conical block backward along the No. 1 groove. At this time, the fine end of the conical block will come into the air hole. Compared to the coarse end being inside the air hole, the action of the fine end will increase the opening of the air hole, causing the air pressure in the independent sub-cavity to increase and the jet pressure to increase, thus achieving dynamic pressure adjustment. When the load decreases, the motor speed increases, the No. 1 spring is stretched again, the coarse end returns to the inside of the air hole, and the air pressure drops back to the normal level.
[0020] 3. This device adopts an independent drying, crushing, and airflow-assisted cleaning mode, which does not rely on a water environment. The cutting blade directly cuts the waste wire mechanically, and the airflow inside the rotating roller is ejected through the air holes to blow off the waste wire. The entire operation does not involve a water environment, and there is no need to waterproof the core components such as the motor, air pump, and guide tube, which fundamentally reduces the equipment manufacturing cost and maintenance difficulty. At the same time, the dry environment avoids the risk of component corrosion and circuit failure, extends the service life of the equipment, and solves the shortcomings of the second comparative document.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.
[0025] A waste textile filament recycling and processing device includes: a recycling box 1, a rotating roller 2, and a support plate 3. The support plate 3 is fixedly connected to the interior of the recycling box 1. The two ends of the rotating roller 2 are rotatably connected to the inner wall of the recycling box 1 and the support plate 3, respectively. An air collection box 4 is installed on the outer wall of the recycling box 1. A cutting blade 9 is fixed to the exterior of the rotating roller 2. Air holes 44 communicating with the interior are evenly distributed on the outer surface of the rotating roller 2. An airflow balancing structure is installed inside the rotating roller 2. The interior of the rotating roller 2 is hollow. The airflow balancing structure includes a guide cylinder 5 fixed inside the rotating roller 2 and three partitions 43 equidistantly arranged outside the guide cylinder 5. Divided into four independent sub-cavities 6 by three partitions 43, the guide tube 5 has four directional guide holes 7 evenly distributed, each corresponding to one of the four independent sub-cavities 6. The center of the guide tube 5 is connected to the gas collection box 4 through a connecting pipe 8, and the guide tube 5 rotates around the connecting pipe 8. The diameter of the four directional guide holes 7 gradually increases from the end closer to the connecting pipe 8 to the end farther away from the connecting pipe 8 to compensate for the pressure loss of the airflow along the axial direction of the rotating roller 2. The recovery box 1 is equipped with an air pump 14, and the air pump 14 is connected to the gas collection box 4 through a pipeline. The inside of the guide tube 5 is provided with four sets of equidistantly distributed dynamic pressure regulating structures to cooperate with the directional guide holes 7.
[0026] It should be noted that the air pump 14 is designed to replenish gas when the elastic airbag in the comparative document 1 is unstable in inflation, thus complementing the elastic airbag in the comparative document. When the air pressure in the air collection box 4 reaches the critical value of the pressure valve on the connecting pipe 8, the gas in the air collection box 4 is injected into the interior of the guide tube 5 through the connecting pipe 8, and then enters the interior of the four independent sub-cavities 6 through the directional guide holes 7. Since the diameter of the directional guide holes 7 gradually increases from the end near the connecting pipe 8 to the end away from the connecting pipe 8 (for example, the diameter is 3mm at the near end and 5mm at the far end), it compensates for the pressure loss of the airflow along the axis of the rotating roller 2, so that the air pressure in each independent sub-cavity 6 is the same and balanced. Each independent sub-cavity 6 corresponds to two cutting blades 9, which solves the problem of uneven airflow pressure in the axial direction of the rotating roller 2 in the comparative document. This makes the waste wire blown off at each position on the outside of the rotating roller 2 have the same effect, and prevents the waste wire from getting entangled in the rotating roller 2 at positions with weak airflow.
[0027] Furthermore, the dynamic pressure regulating structure includes a support rod 10 inside the flow guide cylinder 5. The support rod 10 is provided with a first groove 11. A movable plate 12 is slidably connected to the support rod 10 along the first groove 11. A first spring 13 is fixed inside the flow guide cylinder 5, and one end of the first spring 13 is fixedly connected to the movable plate 12. A conical block 15 is fixed on the movable plate 12. The conical block 15 is located inside the directional flow guide hole 7. The conical block 15 includes a thick end 23 and a thin end 24. Specifically, the conical block 15 has a conical surface, with the larger diameter end being the thick end 23 and the smaller diameter end being the thin end 24.
[0028] It can be concluded that under normal conditions, i.e., when there is no coarse waste wire wrapped around it, the centrifugal force of the rotating roller 2 is large, which makes the centrifugal force on the first spring 13 large. At this time, the centrifugal force overcomes the resistance of the first spring 13, thereby causing the first spring 13 to be stretched, and then carrying the movable plate 12 and the conical block 15 to maintain their position. Figure 3 In other words, when the centrifugal force of the roller 2 is large, the coarse end 23 of the conical block 15 is located inside the air hole 44. However, when the cutting blade 9 encounters coarse waste wire, the load on the roller 2 increases, and the rotation speed decreases. The centrifugal force on the first spring 13 decreases, and the first spring 13 retracts part of its original position and pulls the movable plate 12 and the conical block 15 backward along the first groove 11. At this time, the fine end 24 of the conical block 15 will come into the air hole 44. Compared with the coarse end 23 being located inside the air hole 44, the action of the fine end 24 will make the opening of the air hole 44 larger, which will increase the air pressure in the independent sub-cavity 6 and enhance the jet pressure, thereby achieving dynamic pressure adjustment. When the load decreases, the motor speed increases, the first spring 13 is stretched again, the coarse end 23 returns to the inside of the air hole 44, and the air pressure drops back to the normal level.
[0029] Furthermore, the air hole 44 is provided with a sealing structure inside. The sealing structure is used to prevent waste wire from entering the inside of the roller 2 through the air hole 44 when the equipment is not in operation. The sealing structure includes four thin sheets 16 made of elastic material fixed to the inner wall of the air hole 44, and the surface of the thin sheets 16 is provided with wire guide grooves 17. Blades 18 are distributed inside the wire guide grooves 17, and the directional flow guide hole 7 is provided with a spiral groove 19.
[0030] It should be noted that when the roller 2 is not in operation, the four deformable sheets 16 inside the air hole 44 naturally close, directly blocking the waste filament from entering the roller 2 from the air hole 44, thereby avoiding blockage of the internal channel. When the roller 2 is in operation, the airflow blown out from the air hole 44 acts on the sheets 16, causing the sheets 16 to deform and open under the airflow pressure, allowing the airflow to pass smoothly. At the same time, when the filament enters the guide groove 17 with the external airflow, the centrifugal force generated by the rotation of the roller 2 causes the filament to actively contact the blade 18 and be cut into short segments. The short filament segments are more easily discharged with the airflow or subsequent cleaning operations, and thus will not adhere to or wrap around the outside of the roller 2.
[0031] Furthermore, the cutting blade 9 is equipped with a cooling structure inside, which works in conjunction with the airflow in the independent sub-cavity 6. The interior of the cutting blade 9 is a hollow groove 20, which is connected to an air inlet 21 that extends into the interior of the independent sub-cavity 6. An exhaust port 22 is provided on the side of the cutting blade 9, and a one-way valve 25 is installed in the exhaust port 22. The cooling structure also includes a metal conduction rod 26 fixed to the cutting blade 9. One end of the metal conduction rod 26 is located inside the independent sub-cavity 6, and the other end of the metal conduction rod 26 extends into the interior of the hollow groove 20.
[0032] Specifically, the cutting blade 9 generates heat due to friction with the waste wire, reducing its working time. The airflow temperature in the independent sub-cavities 6 is lower than that of the cutting blade 9. The airflow in the four independent sub-cavities 6 simultaneously enters the hollow groove 20 from the air inlet 21. The airflow carries away the heat of the cutting blade 9 as it flows through the hollow groove 20. As the air pressure in the hollow groove 20 increases and reaches the threshold of the one-way valve 25, the one-way valve 25 opens under the action of the air pressure, releasing the internally heated airflow. At the same time, under the action of the metal conduction rod 26, the temperature in the hollow groove 20 can be conducted out. Then, when the airflow exits from the air hole 44, it carries away this part of the temperature, thereby cooling down the cutting blade 9 and increasing its working time.
[0033] In addition, the bottom of the recycling bin 1 is provided with an impurity collection structure and a collection box 27. The impurity collection structure includes a second groove 28 on the inner wall of the recycling bin 1. A slider 29 is slidably connected to the second groove 28. A third spring 42 is provided inside the second groove 28 and connected to the bottom of the slider 29. The slider 29 and the collection box 27 are provided with insertion holes. A pin 30 is inserted into the insertion holes of the slider 29 and the collection box 27 to realize the installation and removal of the collection box 27. The impurity collection structure also includes an emergency box 45 that can be pulled out at the bottom of the recycling bin 1 and at the bottom of the collection box 27. A plate-shaped magnet 46 is installed on the side wall of the emergency box 45. An iron plate 47 is fixed to the bottom of the collection box 27. The magnet 46 and the iron plate 47 cooperate with each other.
[0034] Furthermore, the impurity collection structure also includes a material drop trough 31 at the bottom of the collection box 27. A baffle 32 is fixed inside the material drop trough 31, and the baffle 32 has a through hole 33. A top plate 34 is fixed at the bottom of the emergency box 45. The width of the top plate 34 is smaller than the width of the through hole 33. A third groove 35 is provided on the inner wall of the collection box 27. A lifting plate 36 is slidably connected along the third groove 35 inside the collection box 27. In its initial state, the lifting plate 36 is located inside the material drop trough 31 and contacts the top of the baffle 32.
[0035] Specifically, impurities in the waste wire are sorted and shaken into the collection box 27. As the amount of impurities increases, the weight of the collection box 27 decreases. At this time, the slider 29 slides down along the second groove 28 and compresses the third spring 42. As the weight of the collection box 27 continues to increase, the collection box 27 continues to descend and its bottom contacts the top of the emergency box 45. The top plate 34 passes through the through hole 33 and lifts the lifting plate 36 along the third groove 35 to open the discharge chute 31. Then, the impurities in the collection box 27 fall into the emergency box 45, thereby delaying the cleaning time of the collection box 27. The iron plate 47 at the bottom of the collection box 27 is strongly attracted by the magnet 46 on the inner wall of the emergency box 45, which helps to prevent the collection box 27 from resetting after the material is discharged and affecting the use of the reminder component.
[0036] In this embodiment, there is no single way to remove impurities, but all of them require pulling out the pin 30 to disassemble the collection box 27. The first way is to pull out the collection box 27 and the emergency box 45 together without separating them. The second way is to manually lift the collection box 27 to separate the iron plate 47 from the magnet 46, and then take out the collection box 27 and the emergency box 45 respectively to pour out the impurities. The method is not fixed.
[0037] Specifically, the impurity collection structure is linked to a reminder component, which includes a reminder rod 37 slidably connected to the recycling bin 1. A second spring 38 is provided on the outside of the reminder rod 37. One end of the reminder rod 37 is located inside the recycling bin 1 and is fixed with a wedge block 39. The reminder rod 37 has reminder stripes 40 that gradually become darker from the end away from the wedge block 39 to the end closer to the wedge block 39. The bottom of one end of the collection box 27 is provided with a beveled edge 41 that cooperates with the wedge block 39.
[0038] It can be concluded that when the collection box 27 sinks, its bottom inclined edge 41 will contact the wedge block 39 of the reminder component and push the wedge block 39, thereby driving the reminder rod 37 to slide outward along the recycling box 1, while compressing the external second spring 38. As the weight of the collection box 27 increases and the sinking amount increases, the length of the reminder rod 37 pushed out gradually becomes longer, and the reminder stripes 40 on its surface, from light to dark, will be gradually exposed to the outside of the recycling box 1. The depth of exposure of the reminder stripes 40 directly reflects the amount of impurities collected in the collection box 27. When the collection box 27 is full of impurities and needs to be cleaned, the reminder rod 37 is pushed out to its maximum length, and the dark reminder stripes 40 on its outside are fully visible, realizing a full material reminder.
[0039] Working principle: Through the set airflow balancing structure, the set air pump 14 can supplement gas when the elastic airbag in the comparison document 1 is unstable, complementing the elastic airbag in the comparison document. When the air pressure in the air collection box 4 reaches the critical value of the pressure valve on the connecting pipe 8, the gas in the air collection box 4 is injected into the interior of the guide tube 5 through the connecting pipe 8, and then enters the interior of the four independent sub-cavities 6 through the directional guide holes 7. Since the diameter of the directional guide holes 7 gradually increases from the end near the connecting pipe 8 to the end away from the connecting pipe 8, for example, the diameter of the hole at the near end is 3mm and the diameter of the hole at the far end is 5mm, it compensates for the pressure loss of the airflow along the axis of the rotating roller 2, so that the air pressure in each independent sub-cavity 6 is the same and balanced. Each independent sub-cavity 6 corresponds to two cutting blades 9, which solves the problem of uneven airflow pressure in the axis of the rotating roller 2 in the comparison document. In this way, the waste wire blown off at each position on the outside of the rotating roller 2 has the same effect, preventing the waste wire from getting entangled in the rotating roller 2 at the position with weak airflow.
[0040] Because the roller 2 in the prior art 1 relies on the pressure valve on the external connecting pipe 8 to control the pressure, when the cutting blade 9 encounters thicker waste wire (increased load), the risk of waste wire entanglement increases, requiring higher air jet pressure. However, the pressure valve cannot be adjusted in real time, which will result in insufficient air jet when the load is high.
[0041] With the dynamic pressure adjustment structure, under normal conditions, that is, when there is no coarse waste wire wrapped around, when the roller 2 rotates at high speed, the centrifugal force pushes the movable plate 12 to overcome the tension of the first spring 13 and move it outward, so that the coarse end 23 of the conical block 15 comes into the air hole 44.
[0042] However, when the cutting blade 9 encounters coarse waste wire, the load on the rotating roller 2 increases, and the rotation speed decreases. Since the torque of the motor driving the rotating roller 2 is constant, the rotation speed decreases as the load increases. The centrifugal force on the movable plate 12 and the first spring 13 decreases, and the first spring 13 retracts part of its original position and pulls the movable plate 12 and the conical block 15 backward along the first groove 11. At this time, the thin end 24 of the conical block 15 will come into the interior of the air hole 44. Compared with the coarse end 23 located inside the air hole 44, the action of the thin end 24 will increase the opening of the air hole 44, thereby increasing the air pressure in the independent sub-cavity 6 and enhancing the jet pressure, thus achieving dynamic pressure adjustment. When the load decreases, the motor speed increases again, the first spring 13 is stretched again, the coarse end 23 returns to the interior of the air hole 44, and the air pressure drops back to the normal level.
[0043] It should be explained that if high-pressure blowing is used continuously, some waste filaments may be broken into excessively short fiber segments due to excessive pressure. These short fibers are prone to problems such as uneven mixing and reduced fiber strength during subsequent recycling and reuse. However, the dynamic pressure regulating structure in this case can avoid the damage to the morphology of waste filaments caused by excessive high pressure, prevent excessive fiber breakage, help maintain the length of recycled fibers, and improve the utilization value of waste filament recycling and the quality of finished products.
[0044] With the sealing structure, when the roller 2 is not in operation, the four deformable sheets 16 inside the air hole 44 naturally close, directly blocking the waste filament from entering the roller 2 from the air hole 44, thus avoiding blockage of the internal channel. When the roller 2 is in operation, the airflow blown out from the air hole 44 acts on the sheet 16, causing the sheet 16 to deform and open under the airflow pressure, allowing the airflow to pass smoothly. At the same time, when the filament enters the guide groove 17 with the external airflow, the centrifugal force generated by the rotation of the roller 2 causes the filament to actively contact the blade 18 and be cut into short segments. The short filament segments are more easily discharged with the airflow or subsequent cleaning operations, thus preventing them from adhering to or wrapping around the outside of the roller 2.
[0045] It should be explained that the above-mentioned airflow balancing structure includes directional guide holes 7 and independent sub-cavities 6, which ensure that the airflow pressure at each position of the roller 2 is uniform. This uniform airflow will form a stable and sufficient pressure on the sheet 16, so that the sheet 16 can overcome its own deformation resistance and open synchronously. Since the sheet 16 at all the air holes 44 bears the same balanced airflow pressure, it will not affect the airflow balancing structure. In addition, the sheet 16 is very thin and light, and the airflow consumed when opening the sheet 16 can be ignored.
[0046] Through the cooling structure, the cutting blade 9 generates heat due to friction with the waste wire, reducing its working time. The airflow temperature in the independent sub-cavities 6 is lower than that of the cutting blade 9. The airflow in the four independent sub-cavities 6 enters the hollow groove 20 simultaneously from the air inlet 21. The airflow carries away the heat of the cutting blade 9 as it flows through the hollow groove 20. As the air pressure in the hollow groove 20 increases and reaches the threshold of the one-way valve 25, the one-way valve 25 opens under the action of the air pressure, releasing the internally heated airflow. At the same time, under the action of the metal conduction rod 26, the temperature in the hollow groove 20 can be conducted out. Then, when the airflow exits from the air hole 44, it carries away this part of the temperature, thereby cooling the cutting blade 9 and increasing its working time. Since the airflow balancing structure has ensured that the airflow pressure in the four independent sub-cavities 6 is balanced, and the airflow entering the hollow groove 20 through the air inlet 21 is the same, it will not affect the airflow balancing structure.
[0047] With the impurity collection structure in place, referring to Comparative Document 1, impurities in the waste wire are sorted and shaken off into the collection box 27. As the amount of impurities increases, the weight of the collection box 27 decreases. At this time, the slider 29 slides down along the second groove 28 and compresses the third spring 42. As the weight of the collection box 27 continues to increase, the collection box 27 continues to descend and its bottom contacts the top of the emergency box 45. The top plate 34 passes through the through hole 33 and lifts the lifting plate 36 along the third groove 35. The purpose is to open the material drop chute 31. Then the impurities in the collection box 27 fall into the interior of the emergency box 45, thereby delaying the cleaning time of the collection box 27. The iron plate 47 at the bottom of the collection box 27 is strongly attracted by the magnet 46 on the inner wall of the emergency box 45, which helps to prevent the collection box 27 from resetting after the material is discharged and affecting the use of the reminder component.
[0048] When the collection box 27 sinks, its bottom inclined edge 41 contacts the wedge block 39 of the reminder component and pushes the wedge block 39, thereby driving the reminder rod 37 to slide outward along the recycling box 1, while compressing the external second spring 38. As the weight of the collection box 27 increases and the sinking amount increases, the length of the reminder rod 37 pushed out gradually increases, and the reminder stripes 40 on its surface, from light to dark, will be gradually exposed to the outside of the recycling box 1. The depth of exposure of the reminder stripes 40 directly reflects the amount of impurities collected in the collection box 27. When the collection box 27 is full of impurities and needs to be cleaned, the reminder rod 37 is pushed out to its maximum length, and the dark reminder stripes 40 on its outside are fully visible, realizing a full material reminder.
[0049] Based on the combined structure of the impurity collection system and the warning components, it can be concluded that when the collection box 27 is full of impurities, the warning components will be triggered first. As the weight of the impurities accumulates, the collection box 27 continues to sink. Then, the dark warning stripes 40 on the surface of the warning rod 37 become fully visible, conveying a full signal to the worker. After seeing the warning, the worker can open the door of the recycling box 1 and pull out the latch 30 to remove the collection box 27 for cleaning. If the equipment is in a state of intense operation and it is inconvenient to stop immediately, the collection box 27 will continue to carry impurities and sink further until its bottom contacts the top of the emergency box 45. The top plate 34 at the bottom of the emergency box 45 will penetrate the through hole 33 of the baffle 32, lifting the lifting plate 36 along the third groove 35 to open the drop chute 31. The impurities in the collection box 27 will then fall into the emergency box 45. Through this design, the emergency box 45 can temporarily hold the impurities, effectively delaying the cleaning time of the collection box 27, adapting to working scenarios where the equipment cannot be stopped immediately, and ensuring the continuous operation of the recycling process.
