Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery manufacturing, and particularly relates to a waste textile opening and separating device. Background Art

[0002] The opening of waste textiles is mainly completed by an opening and separating machine, including opening, carding and separating waste fibers, waste yarns, waste fabrics, waste clothes and other waste textiles, and then obtaining recycled fibers through a series of cleaning and carding equipment. Currently, the commonly used opening and separating machines and cleaning and carding equipment on the market all use ordinary fiber holding and carding methods for strong opening, which will cause a large amount of damage to the fibers. Especially, it is necessary to continuously open and remove impurities from the mixture of fibers and yarns through about 10 cleaning and carding equipment, which will further exacerbate the damage to the overall fibers. Therefore, it is necessary to make a reasonable design in combination with the principle of opening and the trajectory of fiber movement, so as to realize that the fibers opened first are separated first, and the fibers opened later are separated later, and truly achieve the timely separation and opening and carding of different intensities of fibers and yarns.

[0003] In recent years, those skilled in the art have conducted a series of studies and correspondingly proposed some methods and devices for timely separating fibers and yarns. For example, in the utility model patent with the application number 202221314106.5, a ragged fiber separation device for fiber regeneration is proposed. This device uses a cloth chute to separate rags and fibers. The principle is that after the mixture of fibers, yarns, and rags is put into this device, it will be affected by the jet air. By taking advantage of the different gravitational effects of materials in various states and using the means of a falling parabola, the fibers and cloth scraps are separated and collected in different areas, which is convenient for subsequent spinning or centralized re-opening and carding. This patented technology avoids repeated opening of fibers and damaging their physical properties. However, there are still some problems: First, the ragged fiber separation device for fiber regeneration is an independent unit and needs to be used in conjunction with the existing opening and separating machine, and cannot be organically integrated with the opening and separating machine, increasing the process and cost; Second, the degree of automation and production efficiency are relatively low; Third, the entanglement between the fed fiber and cloth scrap complex is relatively tight, and it is difficult to immediately disperse and fall through a single airflow, and the actual effect is mediocre. Another example is that in the invention patent with the application number 202410394014.X, a waste textile opener is proposed. This device uses a fiber cloth block separation unit to replace the output structure in the opening and separating machine, and realizes a more thorough separation of fibers and cloth blocks through the method of negative pressure suction. The regenerated fibers directly enter the next process, and the cloth blocks are collected and re-opened, improving the degree of automation and production efficiency, and reducing the overall manufacturing cost and floor area of the equipment. This device avoids repeated opening of fibers and damaging their physical properties and can perform opening, separation, and collection simultaneously online. However, there are still some problems: This device uses an opening unit to open the waste cloth to obtain a comprehensive complex of loose fibers, yarns, and cloth scraps, which relies on the airflow to move forward, and at the same time relies on the vertically upward airflow to float and partition. Then, the airflow dividing plate is used for the final partition flow. The theoretical design is good, but it ignores the fact that the entanglement of the fiber, yarn, and cloth scrap complex is very serious. It is very difficult for the vertically upward airflow to achieve obvious spatial partitioning, and it may not even be able to blow up. The control requirements for the airflow flow rate are too high and too precise. At the same time, there are many impurities in the complex of fibers, yarns, and cloth scraps, which are very easy to block the air supply port, thus making it impossible to stably and effectively eject the vertical airflow. Therefore, the device designed in this patent does not have much practical significance.

[0004] Therefore, it is necessary to research a new device to better and more stably achieve the timely and effective separation of fibers, yarns, and cloth blocks, and at the same time, a cyclic mode of continuous opening and collection of the device can be realized, shortening the processing process of waste textiles and reducing the number of production line configurations.

The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] In order to solve the problem that fibers cannot be stably, timely and effectively separated from yarns and cloth blocks, and the device cannot achieve a continuous cycle mode of opening and collecting, a waste textile opening and separating device is proposed in this application. Figure 1 It is a schematic structural principle diagram of the waste textile opening and separating device in the embodiment of the present invention, as Figure 1As shown in the figure, the waste textile opening and separating device may include: a housing 1 having a feed inlet 11; a feeding mechanism 2, an opening mechanism 3, an air jet mechanism 4, a suction collection mechanism 5, and a blanking circulation mechanism 6 provided in the housing 1; the feeding mechanism 2 is used to convey the material input from the feed inlet 11 to the opening mechanism 3; the opening mechanism 3 includes an opening roller 31, a first holding roller 32, and a second holding roller 33. A holding port 34 for receiving the material from the feeding mechanism 2 and conveying the material to the surface of the opening roller 31 is formed between the first holding roller 32 and the second holding roller 33. The opening roller 31 opens the material and throws the formed mixture downward; the air outlet 41 of the air jet mechanism 4 can jet air to the lower area of the opening roller 31 to disperse the first material and the second material in the mixture, and the falling speed of the first material is less than that of the second material; the suction collection mechanism 5 has a suction port 51 for sucking and collecting the first material; at least a part of the blanking 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.

[0037] When the waste textile opening and separating device in this application separates and opens the materials, the materials are input into the feed inlet 11. The feeding mechanism 2 transports the materials input from the feed inlet 11 to the holding port 34 of the opening mechanism 3. Under the action of the first holding roller 32 and the second holding roller 33, the materials at the holding port 34 are transported to the opening roller 31 for opening. The opening roller 31 opens the materials and throws the formed mixture downward. The air outlet 41 of the air flow injection mechanism 4 jets air towards the lower area of the opening roller 31 to disperse the first material and the second material in the mixture thrown downward 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 and collects the first material through the suction port 51, while the second material falls to the lower material dropping and circulating mechanism 6. The material dropping and circulating mechanism 6 collects the second material and transports it to the feeding mechanism 2 for the next cycle of opening. In the above way, continuous collection of the first material after opening can be achieved, and the second material can be continuously opened to continuously form the first material. The waste textile opening and separating device makes full use of the characteristics of the first material and the second material after opening. When the opening of the opening roller 31 is completed, it utilizes the different trajectories and forces when the first material and the second material are thrown out, and combines with the air flow injection mechanism 4 to continue jetting and dispersing, thus realizing the preliminary separation of the first material and the second material. Then, by utilizing the differences in the floating trajectories and falling speeds of the first material and the second material in the air, the suction collection mechanism 5 sucks and collects the first material, while the second material falls to the lower material dropping and circulating mechanism 6. The material dropping and circulating mechanism 6 collects the second material and transports it to the feeding mechanism 2 for the next cycle of opening until all become the first material. The waste textile opening and separating device in this application can better and more stably achieve the timely and effective separation of the first material and the second material, and at the same time can realize the cyclic mode of continuous opening and collection of the device, shortening the processing process of waste textiles and reducing the number of configurations of the production line.

[0038] As Figure 1 shown, the waste textile opening and separating device may include: a housing 1 having a feed inlet 11; a feeding mechanism 2, an opening mechanism 3, an air flow injection mechanism 4, a suction collection mechanism 5, and a material dropping and circulating mechanism 6 provided in the housing 1. The feed inlet 11 may be located at the upper part of the housing 1, so that the materials input from the feed inlet 11 can automatically reach the feeding mechanism 2 under the action of gravity. The feeding mechanism 2 is used to transport the materials input from the feed 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 in parallel at the outlet of the feeding bin 21; a first conveyor belt 24, the first feeding roller 22 and the second feeding roller 23 convey the materials in the feeding bin 21 onto the first conveyor belt 24, and the first conveyor belt 24 can convey the materials to the holding port 34; a first rotating roller 25 and a second rotating roller 26 located above one end of the first conveyor belt 24 close to the holding port 34. The first rotating roller 25 is closer to the holding port 34 than the second rotating roller 26. The first rotating roller 25 is located above the end of the first conveyor belt 24, and the distance between the first rotating roller 25 and the first conveyor belt 24 is less 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 towards each other under controllable conditions so that the materials in the feeding bin 21 continue to fall through between the first feeding roller 22 and the second feeding roller 23, and the feeding speed can be controlled by the rotational speed. A baffle 27 can be arranged below the first feeding roller 22 and the second feeding roller 23. The materials conveyed downward between the first feeding roller 22 and the second feeding roller 23 are guided by the baffle 27 to fall into the first conveyor belt 24 as much as possible. As Figure 1 shown in, the baffle 27 can be inclined towards the left. The upper surface of the first conveyor belt 24 moves towards the holding port 34. Under the action of the first rotating roller 25 and the second rotating roller 26, the materials are gradually pressed and conveyed into the holding port 34 under controllable conditions. The first conveyor belt 24 can be installed on a third rotating roller 241 and a fourth rotating roller 242. One of the third rotating roller 241 and the fourth rotating roller 242 can be a driving roller, and the other can be a 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 generally arranged in parallel, such as arranged in a direction perpendicular to the paper surface.

[0040] As feasible, the opening mechanism 3 may include an opening roller 31, a first holding roller 32, and a second holding roller 33. A holding opening 34 for receiving the material of the feeding mechanism 2 and conveying the material to the surface of the opening roller 31 is formed between the first holding roller 32 and the second holding roller 33. The upper first holding roller 32 rotates clockwise, and the lower second holding roller 33 rotates counterclockwise. For example, the holding opening 34 may be flush with the center horizontal line of the opening roller 31. The lower side wall of the upper first holding roller 32 may be substantially flush with the lower side wall of the first rotating roller 25, that is, on the same horizontal line. The upper side wall of the lower first holding roller 32 may be substantially flush with the upper side wall of the rotating roller close to the holding opening 34 among the third rotating roller 241 and the fourth rotating roller 242, so as to ensure that the amount of material between the first conveyor belt 24 and the first rotating roller 25 is adapted to the size of the holding opening 34, and to prevent the holding opening 34 from being unable to accommodate too much material. The opening roller 31 opens the material and throws the formed mixture downward. Correspondingly, the opening roller 31 rotates in the clockwise direction. The mixture may include a first material and a second material. Among them, the first material may be fibers that are completely opened and dispersed, and the second material may be materials such as yarns and / or cloth scraps that are not completely opened and dispersed. Due to the respective characteristics of the material properties of the first material and the second material, there are different trajectories and forces when the first material and the second material are thrown out at the end of the opening by the opening roller 31. Therefore, in the subsequent process, the air flow injection mechanism 4 is combined to continue jetting and spraying, so as to realize the preliminary separation of the first material and the second material.

[0041] Further, the air outlet 41 of the air flow injection mechanism 4 can jet air to the lower area of the opening roller 31 to blow the first material and the second material in the mixture. The opening roller 31 has opposite first side ( Figure 1 which is the right side) and second side ( Figure 1 which is the left side in the middle) in the horizontal direction. The first holding roller 32 and the second holding roller 33 are located on the first side of the opening roller 31. The air outlet 41 of the air flow injection mechanism 4 is located obliquely below the second side of the opening roller 31.

[0042] As feasible, the air jet mechanism 4 may have a plurality of air outlets 41. The air outlet 41 at the uppermost position faces the bottom of the opening roller 31, for example, it may be the lowermost bottom of the opening roller 31. The orientations of the plurality of air outlets 41 may be substantially in the horizontal direction and perpendicular to the axis of the opening roller 31. At this time, the orientation of the air outlet 41 at the upper position may be in a tangential state with the lowermost bottom of the opening roller 31. The included angle between the connection line between the air outlet 41 at the lower position and the adjacent air outlet 41 at the upper position and the horizontal direction is between 30° and 60°. The air outlet 41 at the lower position is on the second side direction of the adjacent air outlet 41 at the upper position. Generally speaking, for conventional materials, the flow rate of the gas blown out from the air outlet 41 can be controlled between 0.5 m / s and 5 m / s, and the specific value can be determined according to the type of the material. In the above structure, as the regions where the first material and the second material are partially blown and fall continuously expand, therefore, the position of the air outlet 41 also needs to be adjusted correspondingly, getting farther and farther away, so as to ensure that the blown gas can cover a larger area where the material falls.

[0043] In order to form a plurality of air outlets 41, the air jet mechanism 4 may include a plurality of air blowing pipes 42. The air blowing pipes 42 are arranged vertically and extend in the horizontal direction. A certain distance may be provided between adjacent air outlets 41, and this distance can be adjusted according to the actual situation to ensure the blowing effect.

[0044] As feasible, a sealing plate 12 is arranged in the housing 1. The sealing plate 12 is located on the second side of the opening roller 31, that is, the left side, to block the first material and the second material after being opened and dispersed. The upper end of the sealing plate 12 may be connected to the upper top wall of the housing 1, and the lower end of the sealing plate 12 may be connected to the uppermost air blowing pipe 42.

[0045] As feasible, in order to prevent the air jet mechanism 4 from blowing the first material and the second material towards the first side and the upper oblique direction of the first side of the opening roller 31, the opening mechanism 3 may include: a plurality of blocking members 35. The plurality of blocking members 35 are located obliquely below the first side of the opening roller 31 and are distributed along the circumferential direction of the opening roller 31. A certain distance may be provided between adjacent two blocking members 35. The included angle between the connection line of adjacent two blocking members 35 and the horizontal direction is between 30° and 75°. The first holding roller 32 and the second holding roller 33 are located obliquely above the first side of the blocking members 35.

[0046] Since the falling speed of the first material is less than that of the second material, the suction port 51 of the air suction collection mechanism 5 can be used to suck and collect the first material. At least part of the blanking 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. By utilizing the differences in the floating trajectories and falling speeds of the first material and the second material in the air, the first material is sucked and collected by the air suction collection mechanism 5, while the second material falls to the blanking circulation mechanism 6 below, and the blanking circulation mechanism 6 is used for collection. The air suction collection mechanism 5 may include a first material collection box 53, and the first material collection box 53 is communicated with the suction port 51. The first material sucked by the suction port 51 is all sucked into the first material collection box 53 for collection and storage. It should be noted that the second material may be mixed with the uncollected first material. To avoid sucking the second material, the flow rate of the gas sucked by the suction port of the air suction collection mechanism 5 can be controlled between 0.05 m / s and 1 m / s.

[0047] As a feasible solution, to facilitate the efficient suction and collection of the first material, the suction port 51 is located below the air outlet 41. The orientation of the suction port 51 can be basically horizontal and perpendicular to the axis of the opening roller 31. In addition, the air suction collection mechanism 5 has a plurality of suction ports 51. As a feasible solution, 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 in the second side direction of the adjacent upper suction port 51, so as to ensure the preferential suction effect on the first material. The uppermost suction port 51 is in the first side direction of the lowermost air outlet 41.

[0048] To form a plurality of suction ports 51, the air suction collection mechanism 5 may include a plurality of suction pipes 52. The suction pipes 52 are arranged vertically and extend horizontally. A certain distance can be set between adjacent suction ports 51, and this distance can be adjusted according to the actual situation to ensure the suction and collection effect on the first material.

[0049] In a specific embodiment, the blanking recycling mechanism 6 may include: a second conveyor belt 61 and a third conveyor belt 62. The third conveyor belt 62 extends horizontally and is located below the loosening roller 31 and the air suction port 51 for collecting the second type of material. The third conveyor belt 62 extends horizontally and does not need to be completely horizontal, and may have a certain inclination angle with the horizontal direction. The leftmost side of the third conveyor belt 62 may be located to the left of the air suction port 51 of the lowermost air suction pipe 52. At least a part of the second conveyor belt 61 is in an inclined state, and one place of the inclined second conveyor belt 61 is in contact with the end of the first conveyor belt 24 to convey the second type of material on the second conveyor belt 61 to the first conveyor belt 24. The second conveyor belt 61 is located on the right side of the third conveyor belt 62, and the shown inclined second conveyor belt 61 can also collect the second type of material and convey it to the first conveyor belt 24. The rotation direction of the second conveyor belt 61 is opposite to that of the first conveyor belt 24.

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

[0051] In order to stably convey the second type of material on the second conveyor belt 61 to the first conveyor belt 24, when the end of the first conveyor belt rotates and changes direction, the second type of material on the second conveyor belt 61 is brought onto the upper surface of the first conveyor belt. One end of the first conveyor belt 24 close to the gripping port 34 is higher than the end of the first conveyor belt 24 far from the gripping port 34, and the first conveyor belt 24 is inclined at 10° - 30°.

[0052] Corresponding to the above embodiment, as feasible, the included 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° - 60° to ensure that the material is gradually compacted and conveyed into the gripping port 34 under controllable conditions.

[0053] In the above embodiment, since there is a third conveyor belt 62 below the loosening roller 31, a second conveyor belt 61 in the lower right, and a first conveyor belt 24 on the right, the entire lower right area of the loosening 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 loosening and dispersion, but also through the first conveyor belt 24, it is possible to 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 loosening roller 31. Through the collection of the blanking recycling mechanism 6 and the cyclic input of the collected material onto the first conveyor belt 24, ultimately all the materials input into the waste textile loosening and separating device can be loosened and dispersed into the first type of material and collected by the air suction collection mechanism 5.
