[0002] Nonwoven fabrics are textiles formed without the need for spinning or weaving. They are made by orienting or randomly arranging textile staple fibers or filaments to form a fiber network structure, which is then reinforced using mechanical, thermal bonding or chemical methods. Nonwoven fabrics are new textile products that are flexible, breathable and flat, and are formed by directly using polymer chips, staple fibers or filaments through various fiber network forming methods and consolidation techniques.

[0003] In the nonwoven fabric manufacturing process, the wide nonwoven fabric produced needs to be cut, and a certain amount of waste fabric is generated by cutting. It is necessary to collect the rejected nonwoven fabric or the nonwoven fabric discarded in daily life. The nonwoven fabric is a multi-fiber mixed injection composite material, and the material itself is a composite material combining short plant fibers and polypropylene fibers. The collection of the waste material is different from the online collection and utilization of conventional spunmelt composite fabrics. The composite material combining short plant fibers and long polypropylene fibers cannot be added by being collected and utilized through in-line screw melting. In the prior art, a patent with application number "201410840299.1" and title "Automatic collection and recycling machine for fiberboard cutting material and fiber recycling method" (Patent Document 1) discloses a fiber lumber collection and recycling device, which realizes the collection of discarded fiber lumber through the structure of a crusher and a cyclone separator, etc., but the collected fiber cannot be directly reused, and the collection and utilization efficiency is low.

[0004] Therefore, there is an urgent need for a system for recovering and utilizing waste nonwoven fabrics that is highly efficient in terms of recovery and utilization and that produces high-quality recycled finished products. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor all belong to the technical scope of the present invention.

[0021] The present invention aims to solve the problems existing in the prior art and to provide a system and method for recovering and utilizing waste nonwoven fabric, which uses an agitator to drop fibers in a receiving box evenly across the width of the conveyor belt, and the conveyor belt transports the fibers that are uniform in the width direction into a wood pulp pipe for direct utilization, thereby improving the efficiency of recovering and utilizing the waste fabric and at the same time helping to improve the quality of the finished product formed by mixing the fibers transported evenly in the width direction with the wood pulp.

[0022] In order to make the above objects, features and advantages of the present invention more apparent and comprehensible, the present invention will be described in more detail below with reference to the drawings and specific embodiments.

[0023] With reference to Figures 1 to 4, a system for recovering and utilizing waste nonwoven fabric is provided, comprising a processing unit, a fiber distributor 10 and a conveyor belt 11, the processing unit crushes the waste fabric and defibrates it into fibers, the fiber distributor 10 comprises a receiving box 13 and an agitator 14, the top of the receiving box 13 is connected to the fiber outlet of the processing unit, a dispersed fiber outlet 15 is installed at the bottom of the receiving box 13, a plurality of rows of agitators 14 are uniformly installed at the dispersed fiber outlet 15, each row comprises at least one agitator 14, one end of the conveyor belt 11 is located below the dispersed fiber outlet 15, and the other end is connected to a wood pulp pipe 12 of the nonwoven fabric manufacturing system, and the communication manner is as follows: The wood pulp pipe 12 has a rectangular supply port arranged along its width direction. The length of the supply port is the same as the width of the wood pulp pipe 12. A flow guide plate 22 can be installed outside the supply port to guide the fibers. When the wood pulp pipe 12 is installed vertically using gravity as the wood pulp power source, the supply port is opened on one side of the wood pulp pipe 12, one end of the flow guide plate 22 is welded to the lower edge of the supply port and the other end is installed tilted upward. Baffles 23 are installed on both sides of the flow guide plate 22 to guide the fibers from both sides. In order to prevent the fibers from escaping from the wood pulp pipe 12 and to prevent the wood pulp inside the wood pulp pipe 12 from escaping through the supply port, when a transport pump is used as the wood pulp power source and the wood pulp pipe 12 is installed horizontally, the supply port is opened at the top of the wood pulp pipe 12 and the guide plate can be designed in an annular bell-mouth shape, with the large-diameter end of the bell-mouth shape facing upward and the small-diameter end matching the shape of the supply port and welded to the edge of the supply port to receive and guide the fibers into the wood pulp pipe 12.The width of the dispersed fiber discharge port 15 and the width of the conveyor belt 11 are the same as the width of the wood pulp pipe 12. This width refers to the width along the width direction of the conveyor belt 11. The arrangement direction of the stirrers 14 in the same row is the same as the conveying direction of the conveyor belt 11, and the rotation directions of the stirrers 14 in adjacent rows are opposite. At the end of the processing unit, this device uses the receiving box 13 to receive the recovered fibers, and uses the stirrers 14 and the conveyor belt 11 to convey them to the wood pulp pipe 12 for mixing with the wood pulp, realizing the direct utilization of the fibers, improving the recycling efficiency of waste cloth. During the process of the stirrer 14 dispersing the fibers, the rotation directions of the stirrers 14 in adjacent rows are installed in the opposite direction. When installed in the same direction, it can avoid the problem that the fibers are more on one side and less on the other side along the width direction of the conveyor belt 11. The fibers in the receiving box 13 are uniformly dropped onto the conveyor belt 11 by gravity along the width direction of the conveyor belt 11, and the fibers uniformly conveyed in the width direction can uniformly cover the flow width surface of the square wood pulp pipe 12, which is helpful for improving the quality of the finished product formed by mixing with the wood pulp.

[0024] In order to further improve the uniformity of fiber dropping, a vibrating flat screen can be installed below the dispersed fiber discharge port 15 and the stirrer 14.

[0025] During actual assembly, the distance between the dispersed fiber discharge port 15 and the conveyor belt 11 can be reduced to avoid the fibers being discrete and destroying the uniformity during the falling process. The distance between the dispersed fiber discharge port 15 and the conveyor belt 11 should be greater than the maximum height of the fibers.

[0026] The conveyor belt 11 is in the shape of a mesh curtain, and the mesh diameter of the conveyor belt 11 is less than the minimum diameter of the fiber. An air suction device 16 is installed below the conveyor belt 11, which may be a normal suction fan, and the air inlet of the air suction device 16 is installed corresponding to the conveyor belt 11. The air suction device 16 is used to provide a certain suction force for the fiber on the conveyor belt 11, so as to avoid the destruction of the uniformity of the fiber along the width direction of the conveyor belt 11 due to external wind force, and then mixed with the wood pulp to ensure the quality of the finished product formed.

[0027] The agitator 14 includes a rotating shaft 17 and a number of blades 18, which are installed on the rotating shaft 17 with an upward and downward offset, thereby increasing the dispersion area of ​​the agitator 14, improving the dispersion effect on the fibers, and further improving the uniformity of the fibers after they fall.

[0028] The transmission principle of the transmission shaft of the agitator 14 is as follows: a number of support rods 19 are installed in the receiving box 13, a motor 20 is connected to the position corresponding to the rotation shaft 17 of the support rods 19, and the output end of the motor 20 is transmission-connected to the rotation shaft 17; when selecting the support rods 19, it is possible to reduce their volume in achieving support and avoid a large impact on the falling of the fibers; it is also possible to select the top surface of the support rods 19 to be set in a cone shape with a sharp corner facing upwards, to avoid the fibers accumulating on the upper surface of the support rods 19.

[0029] A height sensor 21 is installed in the receiving box 13 to detect the storage height of the fiber in the box. The height sensor 21 is higher than the agitator 14, and can be adjusted to match the speed at which the fiber enters the receiving box 13 when actually used, to ensure that the storage height of the fiber in the receiving box 13 is not lower than the agitator 14, i.e., the fiber accumulates above the agitation area, and further ensures that each agitator 14 can operate normally, and further ensures the uniformity of the fiber along the width direction of the conveyor belt 11.

[0030] The bottom of the receiving box 13 has a bell-mouth structure, and the small diameter end of the bell-mouth structure is a dispersed fiber outlet 15, which facilitates the bottom of the receiving box 13 to be sufficiently filled with fibers and ensures that the fibers accumulate above the stirring area.

Between the supply mechanism 1 and the crusher 3, between the crusher 3 and the feeder 6, and between the feeder 6 and the separation device 7, centrifugal fans 2 are installed to realize wind-powered transport of the waste cloth, which can reduce the amount of waste cloth remaining in the transport passage compared to transport by the conveyor belt 11. The centrifugal fans 2 also provide a certain suction capacity for the supply mechanism 1, allowing the nonwoven fabric to be sucked in and enter.

[0032] The separating device 7 is a cyclone separator, and the cyclone separator is used to directly separate the fiber and the impurities; or the separating device 7 includes a separation box, an intake pipe, a fan and an impurity storage box 8, the separation box is connected to the feeder 6, the separation box is provided with an intake pipe, the intake pipe connects the separation box and the impurity storage box 8, the fan is installed in the intake pipe, and a filter net is installed at one end of the intake pipe close to the separation box, the mesh diameter of the filter net is less than the minimum diameter of the shredded waste cloth, and the fan is used to suck the lighter impurities into the impurity storage box 8 to complete the separation of the impurities and the fiber, and an exhaust port is opened in the impurity storage box 8, and a filter net is installed at the exhaust port, and the filter net is used to block the impurities separated from the fiber.

[0033] A diverter valve 4 is installed between the grinder 3 and the feeder 6 to control the flow direction of the waste cloth. The feed port of the diverter valve 4 is connected to the discharge port of the grinder 3. The diverter valve 4 has two discharge ports. The discharge ports of the two diverter valves 4 are respectively connected to the feeder 6 and a temporary storage box 5 for temporarily storing the waste cloth. When the downstream work machine breaks down or needs inspection and repair, the waste cloth can be stored in the temporary storage box 5 first, and then the waste cloth in the temporary storage box 5 can be manually transferred to the supply mechanism 1 and continued to be fed. Specifically, the structure of the diverter valve 4 can be installed in a three-way structure, and an opening and closing valve is installed at the two through holes which are the discharge ports, an exhaust port is opened in the temporary storage box 5, and a filter net is installed at the exhaust port, and the filter net is used to block the waste cloth.
