Description

Technical Field

[0001] This invention relates to the field of textile machinery manufacturing technology, and in particular to a device for opening and separating waste textiles. Background Technology

[0002] The opening and sorting of waste textiles is mainly accomplished by an opening and separating machine. This includes opening, combing, and separating waste fibers, yarns, fabrics, and clothing, followed by a series of cleaning and carding processes to obtain recycled fibers. Currently, commonly used opening and separating machines and cleaning and carding equipment employ ordinary fiber-holding combing methods for strong opening, which causes significant fiber damage. In particular, the mixture of fibers and yarns undergoes approximately 10 cleaning and carding processes to continuously open and remove impurities, further exacerbating the damage to the overall fibers. Therefore, a reasonable design is needed that combines the principles of opening and the trajectory of fiber movement to ensure that fibers opened first are separated first, and fibers opened later are separated later, truly achieving timely separation of fibers and yarns and differentiated opening and combing based on intensity.

[0003] In recent years, those skilled in the art have conducted a series of studies and proposed corresponding methods and devices for timely separation of fibers and yarns. For example, a utility model patent with application number 202221314106.5 proposes a fiber separation device for fiber regeneration. This device uses a conveyor belt to separate rags and fibers. The principle is that after the mixture of fibers, yarns, and rags is fed into the device, it is affected by airflow. Utilizing the different gravitational effects of materials in various states, a parabolic falling trajectory is used to separate and collect the fibers and rags in sections, facilitating subsequent spinning or centralized re-opening and carding. This patented technology avoids repeated opening of fibers, which damages their physical properties. However, it still has some problems: First, the fiber separation device for fiber regeneration is an independent unit and needs to be used in conjunction with an existing opening and separating machine, rather than being organically integrated, increasing the process and cost; second, the degree of automation and production efficiency are low; third, the fed fiber and rag compound is tightly entangled, making it difficult to immediately disperse and fall through a single airflow, resulting in only average practical effect. For example, invention patent application number 202410394014.X proposes a waste textile opening machine. This device replaces the output structure of the opening and separating machine with a fiber and fabric block separation unit. It achieves more thorough separation of fibers and fabric blocks through negative pressure suction. Regenerated fibers directly enter the next process, while fabric blocks are collected for repeated opening, improving automation and production efficiency, and reducing the overall manufacturing cost and floor space of the equipment. This device avoids damage to the physical properties of fibers from repeated opening and can perform opening, separation, and collection online simultaneously. However, it still has some problems: the device uses an opening unit to open up the waste fabric, resulting in a composite of loose fibers, yarns, and fabric scraps. It moves forward by airflow and is also lifted and partitioned by vertical upward airflow. The final partitioned flow is then achieved by an airflow dividing plate. The theoretical design is good, but it ignores the fact that the entanglement of the fiber, yarn, and fabric scrap composite is very serious. It is difficult for the vertical upward airflow to achieve obvious spatial partitioning, or even to blow it up. The control of airflow is too high and too precise. At the same time, the composite of fiber, yarn, and fabric scraps contains many impurities, which can easily clog the air inlet, thus making it impossible to stably and effectively eject vertical airflow. Therefore, the device designed in this patent does not have much practical significance.

[0004] Therefore, it is necessary to develop a new device to achieve better and more stable timely and effective separation of fibers, yarns, and fabric pieces, while also enabling a continuous opening and collection cycle, shortening the processing flow of waste textiles and reducing the number of production lines required. Summary of the Invention

[0028] The waste textile opening and separation device of this application, when opening and separating materials, inputs the material into the feed inlet. The feeding mechanism conveys the material input into the feed inlet to the gripping port of the opening mechanism. Under the action of the first gripping roller and the second gripping roller, the material at the gripping port is conveyed to the opening roller for opening. The opening roller opens the material and throws the resulting mixture downward. The air jet mechanism sprays air into the area below the opening roller to disperse the first and second materials in the mixture thrown downward by the opening roller. Since the falling speed of the first material is less than that of the second material, the suction collection mechanism sucks in and collects the first material through the suction port, while the second material falls to the material circulation mechanism below. The material circulation mechanism collects the second material and conveys it to the feeding mechanism for the next cycle of opening. In this way, the first material after opening can be continuously collected, and the second material can be continuously opened to continuously form the first material. This waste textile opening and separation device fully utilizes the characteristics of the first and second materials after opening. At the end of the opening process, it leverages the different trajectories and forces experienced by the first and second materials upon ejection, combined with an air jet mechanism for continued air dispersion, thus achieving initial separation of the two materials. Subsequently, utilizing the difference in the airborne trajectories and falling speeds of the first and second materials, a suction collection mechanism draws in and collects the first material, while the second material falls to a lower material circulation mechanism. This mechanism collects the second material and transports it to the feeding mechanism for the next cycle of opening, until all of it is converted into the first material. The waste textile opening and separation device of this application can achieve better and more stable timely and effective separation of the first and second materials, while also enabling a continuous opening and collection cycle, shortening the waste textile processing flow and reducing the number of production lines required.

[0036] In order to solve the problems of unstable, timely and effective separation of fibers from yarns and fabric pieces, and the inability of the device to achieve a continuous opening and collection cycle, this application proposes a waste textile opening and separation device. Figure 1 This is a schematic diagram illustrating the structural principle of the waste textile opening and separation device in an embodiment of the present invention, as shown below. Figure 1As shown, the waste textile opening and separation device may include: a housing 1 with an inlet 11; a feeding mechanism 2, an opening mechanism 3, an air jet mechanism 4, a suction collection mechanism 5, and a material discharge circulation mechanism 6 disposed within the housing 1; the feeding mechanism 2 is used to transport the material input from the inlet 11 to the opening mechanism 3; the opening mechanism 3 includes an opening roller 31, a first gripping roller 32, and a second gripping roller 33, with a gripping opening 34 formed between the first gripping roller 32 and the second gripping roller 33 to receive the material from the feeding mechanism 2 and transport the material to the surface of the opening roller 31; the opening roller 31... The material is loosened and the resulting mixture is thrown downwards; the air outlet 41 of the air jet mechanism 4 can spray air into the area below the loosening roller 31 to disperse the first and second materials in the mixture, with the falling speed of the first material being less than that of the second material; the suction collection mechanism 5 has a suction port 51 for sucking in and collecting the first material; at least part of the material discharge circulation mechanism 6 is located below the loosening roller 31 and the suction port 51 for collecting the second material and conveying it to the feeding mechanism 2 for the next cycle of loosening.

[0037] In this application, the waste textile opening and separation device inputs the material into the feed inlet 11 during the opening and separation process. The feeding mechanism 2 then conveys the material input into the feed inlet 11 to the gripping port 34 of the opening mechanism 3. Under the action of the first gripping roller 32 and the second gripping roller 33, the material at the gripping port 34 is conveyed to the opening roller 31 for opening. The opening roller 31 opens the material and throws the resulting mixture downwards. The air outlet 41 of the air jet mechanism 4 sprays air into the area below the opening roller 31 to disperse the first and second materials in the mixture thrown downwards by the opening roller 31. Since the falling speed of the first material is less than that of the second material, the suction collection mechanism 5 sucks in and collects the first material through the suction port 51, while the second material falls to the material circulation mechanism 6 below. The material circulation mechanism 6 collects the second material and conveys it to the feeding mechanism 2 for the next cycle of opening. The above method enables the continuous collection of the first type of material after opening, while the second type of material is continuously opened to form the first type of material. This waste textile opening and separation device fully utilizes the characteristics of the first and second types of material after opening. At the end of opening by the opening roller 31, the different trajectories and forces experienced by the first and second types of material when they are thrown, combined with the air jet mechanism 4 continuing to spray and disperse, achieves initial separation of the first and second types of material. Then, utilizing the difference in the floating trajectory and falling speed of the first and second types of material in the air, the suction collection mechanism 5 sucks in and collects the first type of material, while the second type of material falls to the material circulation mechanism 6 below. The material circulation mechanism 6 collects the second type of material and transports it to the feeding mechanism 2, thus performing the next cycle of opening until all of it becomes the first type of material. The waste textile opening and separation device of this application can achieve better and more stable timely and effective separation of the first and second types of material, while also enabling a continuous opening and collection cycle, shortening the processing flow of waste textiles and reducing the number of production line configurations.

[0038] like Figure 1 As shown, the waste textile opening and separation device may include: a housing 1 with an inlet 11; a feeding mechanism 2, an opening mechanism 3, an air jet mechanism 4, a suction collection mechanism 5, and a material discharge circulation mechanism 6 disposed within the housing 1. The inlet 11 may be located at the upper part of the housing 1, so that the material input from the inlet 11 can automatically reach the feeding mechanism 2 under the action of gravity. The feeding mechanism 2 is used to transport the material input from the inlet 11 to the opening mechanism 3.

[0039] The feeding mechanism 2 may include: a feeding bin 21 formed below the feeding port 11; a first feeding roller 22 and a second feeding roller 23 arranged side-by-side at the outlet of the feeding bin 21; a first conveyor belt 24, on which the first feeding roller 22 and the second feeding roller 23 transport material from the feeding bin 21 to the first conveyor belt 24, which can transport material to the gripping port 34; a first rotating roller 25 and a second rotating roller 26 located above the end of the first conveyor belt 24 near the gripping port 34. The first rotating roller 25 is closer to the gripping port 34 than the second rotating roller 26, and the first rotating roller 25 is located above the end of the first conveyor belt 24. The distance between the first rotating roller 25 and the first conveyor belt 24 is smaller than the distance between the second rotating roller 26 and the first conveyor belt 24. The first feeding roller 22 and the second feeding roller 23 can rotate toward each other under controllable conditions so that the material from the feeding bin 21 continues to flow between the first feeding roller 22 and the second feeding roller 23, and the feeding speed can be controlled by the rotation speed. A baffle 27 can be provided below the first feed roller 22 and the second feed roller 23. The baffle 27 guides the material conveyed downward between the first feed roller 22 and the second feed roller 23 so that it falls onto the first conveyor belt 24 as much as possible. Figure 1 As shown, baffle 27 can tilt to the left. The upper surface of the first conveyor belt 24 moves toward the gripping opening 34. Under the action of the first rotating roller 25 and the second rotating roller 26, the material is gradually compressed and conveyed to the gripping opening 34 under controllable conditions. The first conveyor belt 24 can be mounted on the third rotating roller 241 and the fourth rotating roller 242. One of the third rotating roller 241 and the fourth rotating roller 242 can be the driving roller, and the other can be the driven roller. The third rotating roller 241 and the fourth rotating roller 242 rotate counterclockwise. The first rotating roller 25, the second rotating roller 26, the third rotating roller 241, and the fourth rotating roller 242 can be arranged generally in parallel, such as perpendicular to the paper surface.

[0040] Alternatively, the opening mechanism 3 may include an opening roller 31, a first gripping roller 32, and a second gripping roller 33. A gripping opening 34 is formed between the first gripping roller 32 and the second gripping roller 33 to receive material from the feeding mechanism 2 and convey the material to the surface of the opening roller 31. The upper first gripping roller 32 rotates clockwise, and the lower second gripping roller 33 rotates counterclockwise. For example, the gripping opening 34 may be flush with the center horizontal line of the opening roller 31. The lower sidewall of the upper first gripping roller 32 may be substantially flush with the lower sidewall of the first rotating roller 25, i.e., on the same horizontal line. The upper sidewall of the lower first gripping roller 32 may be substantially flush with the upper sidewall of the rotating roller closest to the gripping opening 34 among the third and fourth rotating rollers 241 and 242, thereby ensuring that the amount of material between the first conveyor belt 24 and the first rotating roller 25 is adapted to the size of the gripping opening 34, avoiding excessive material that the gripping opening 34 cannot accommodate. The opening roller 31 opens the material and throws the resulting mixture downwards. Correspondingly, the opening roller 31 rotates clockwise. The mixture may include a first material and a second material, wherein the first material may be fully opened and dispersed fibers, and the second material may be incompletely opened and dispersed yarns and / or fabric scraps. Due to the different material properties of the first and second materials, they have different trajectories and forces when they are thrown out at the end of the opening process by the opening roller 31. Therefore, in the subsequent process, air jetting mechanism 4 continues to spray and disperse the material, thereby achieving the initial separation of the first and second materials.

[0041] Furthermore, the air outlet 41 of the air jet mechanism 4 can spray air into the area below the opening roller 31 to disperse the first and second materials in the mixture. The opening roller 31 has opposing first sides in the horizontal direction ( Figure 1 (right side) and second side ( Figure 1 (The middle is on the left), the first gripping roller 32 and the second gripping roller 33 are located on the first side of the opening roller 31. The air outlet 41 of the air jet mechanism 4 is located diagonally below the second side of the opening roller 31.

[0042] As an option, the airflow injection mechanism 4 can have multiple air outlets 41, with the uppermost air outlet 41 facing the bottom of the opening roller 31, for example, the very bottom of the opening roller 31. The orientation of the multiple air outlets 41 can be substantially horizontal, perpendicular to the axis of the opening roller 31. In this case, the orientation of the upper air outlet 41 can be tangent to the bottom of the opening roller 31. The angle between the line connecting the lower air outlet 41 and the adjacent upper air outlet 41 and the horizontal direction is between 30° and 60°, with the lower air outlet 41 located on the second side of the adjacent upper air outlet 41. Generally, for conventional materials, the flow velocity of the gas blown from the air outlet 41 can be controlled between 0.5 m / s and 5 m / s, with the specific value determined according to the type of material. In the above structure, as the area where the first and second materials are partially blown away and fall continuously expands, the position of the air outlet 41 also needs to be adjusted accordingly, moving further and further away, to ensure that the blown gas can cover a larger area where the materials fall.

[0043] To form multiple air outlets 41, the airflow jetting mechanism 4 may include multiple air blowing pipes 42, which are arranged vertically and extend horizontally. Adjacent air outlets 41 may be spaced a certain distance apart, which can be adjusted according to actual conditions to ensure the blowing effect.

[0044] As an option, a sealing plate 12 is provided inside the housing 1. The sealing plate 12 is located on the second side, i.e. the left side, of the opening roller 31 to block the first and second materials after opening and dispersion. The upper end of the sealing plate 12 can be connected to the upper top wall of the housing 1, and the lower end of the sealing plate 12 can be connected to the uppermost air pipe 42.

[0045] As a feasible solution, to prevent the airflow jetting mechanism 4 from blowing the first and second materials toward the first side and above the first side of the opening roller 31, the opening mechanism 3 may include: a plurality of baffles 35 located below the first side of the opening roller 31 and distributed circumferentially along the opening roller 31. Adjacent baffles 35 may have a certain spacing. The angle between the line connecting two adjacent baffles 35 and the horizontal direction is between 30° and 75°. The first gripping roller 32 and the second gripping roller 33 are located above the first side of the baffles 35.

[0046] Since the falling speed of the first material is less than that of the second material, the suction port 51 of the suction collection mechanism 5 can be used to suck in and collect the first material. At least part of the material discharge circulation mechanism 6 is located below the opening roller 31 and the suction port 51 to collect the second material and convey it to the feeding mechanism 2 for the next cycle of opening. Utilizing the difference in the floating trajectory and falling speed of the first and second materials in the air, the suction collection mechanism 5 sucks in and collects the first material, while the second material falls to the material discharge circulation mechanism 6 below and is collected by the material discharge circulation mechanism 6. The suction collection mechanism 5 may include a first material collection box 53, which is connected to the suction port 51. All the first material sucked in by the suction port 51 is sucked into the first material collection box 53 for collection and storage. It should be noted that the second material may contain uncollected first material. To prevent the second material from being sucked in, the flow rate of the gas drawn in through the suction port of the suction collection mechanism 5 can be controlled between 0.05 m / s and 1 m / s.

[0047] As a feasible option, to facilitate efficient intake and collection of the first material, the suction port 51 is located below the outlet 41. The orientation of the suction port 51 can be substantially horizontal, perpendicular to the axis of the opening roller 31. Furthermore, the suction collection mechanism 5 has multiple suction ports 51. As a feasible option, the angle between the line connecting the lower suction port 51 and the adjacent upper suction port 51 and the horizontal direction is between 30° and 60°. The lower suction port 51 is located on the second side of the adjacent upper suction port 51, thereby ensuring preferential intake of the first material. The uppermost suction port 51 is located on the first side of the lowermost outlet 41.

[0048] To form multiple air intakes 51, the air collection mechanism 5 may include multiple air intake pipes 52, which are arranged vertically and extend horizontally. Adjacent air intakes 51 may be spaced a certain distance apart, which can be adjusted according to actual conditions to ensure effective collection of the first material.

[0049] In one specific embodiment, the material feeding and recycling mechanism 6 may include a second conveyor belt 61 and a third conveyor belt 62. The third conveyor belt 62 extends horizontally below the opening roller 31 and the suction port 51 for collecting a second type of material. The third conveyor belt 62 extends horizontally, but does not need to be completely horizontal; it may have a certain angle with the horizontal. The leftmost side of the third conveyor belt 62 may be located to the left of the suction port 51 of the lowermost suction pipe 52. At least partially, the second conveyor belt 61 is inclined, and one part of the inclined second conveyor belt 61 contacts the end of the first conveyor belt 24 to transfer the second type of material on the second conveyor belt 61 to the first conveyor belt 24. The second conveyor belt 61 is located to the right of the third conveyor belt 62, and the inclined second conveyor belt 61 may also collect the second type of material and transfer it to the first conveyor belt 24. The rotation direction of the second conveyor belt 61 is opposite to the rotation direction of the first conveyor belt 24.

[0050] In the above embodiment, the second conveyor belt 61 can be driven by the fifth rotating roller 611, the sixth rotating roller 612, and the seventh rotating roller 613, and the trajectory of the second conveyor belt 61 is triangular. The third conveyor belt 62 can be driven by the eighth rotating roller 621 and the ninth rotating roller 622.

[0051] In order to ensure that the second material on the second conveyor belt 61 is stably conveyed to the first conveyor belt 24, the second material on the second conveyor belt 61 is brought into the upper surface of the first conveyor belt when the end of the first conveyor belt rotates and changes phase. The end of the first conveyor belt 24 near the grip opening 34 is higher than the end of the first conveyor belt 24 away from the grip opening 34, and the first conveyor belt 24 is inclined at 10°-30°.

[0052] Corresponding to the above embodiment, as a feasible option, the angle between the line connecting the first rotating roller 25 and the second rotating roller 26 and the first conveyor belt 24 is between 30° and 60°, so as to ensure that the material is gradually compressed and conveyed to the gripping opening 34 under controllable conditions.

[0053] In the above embodiment, since the opening roller 31 has a third conveyor belt 62 below it, a second conveyor belt 61 on the lower right, and a first conveyor belt 24 on the right, the entire lower right area of ​​the opening roller 31 is surrounded by conveyor belts. Not only can the second conveyor belt 61 and the third conveyor belt 62 effectively collect the second type of material after opening and dispersing, but the first conveyor belt 24 can also prevent the first type of material and the second type of material from spreading and overflowing to the right and upper right sides of the opening roller 31. The material is collected by the material circulation mechanism 6 and circulated back to the first conveyor belt 24. Finally, all the material input into the waste textile opening and separation device can be opened and dispersed into the first type of material and collected by the suction collection mechanism 5.
