[0002] In the process of recycling waste textile fibers, there is a problem that urgently needs to be solved in the feeding section: after the fabric pieces are fed into the hopper by air conveying or curtain conveying, the fabric pieces will be stacked in layers and disorderly, which will lead to processing difficulties due to the accumulation and adhesion of the fabric pieces, and will not be conducive to subsequent needle punching and flexible disassembly. Summary of the Invention

[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a material handling assembly, the material handling assembly comprising: The feeding hopper has a discharge port; A negative pressure conveying component includes a rotatable rotary conveying surface, at least partially located at the discharge port, and a negative pressure zone is formed in the portion of the rotary conveying surface located at the discharge port. The rotary conveying surface has an upstream side and a downstream side, and a first distance L1 is between the sidewalls of the upstream side and the corresponding side of the discharge port. The thickness of the single-layer fabric sheet is L, satisfying: L≤L1<2L; As the negative pressure conveyor operates, under the constraint of the first spacing, the upstream side of the rotary conveyor surface adsorbs and carries out the single-layer fabric sheet.

[0005] In some embodiments of the first aspect, each segment of the rotary conveyor surface is formed with a negative pressure zone, and the second distance between the sidewalls of the downstream side and the corresponding side of the discharge port is L2, satisfying: 0≤L2<L, so that when the negative pressure conveyor runs, the single-layer fabric adsorbed on the downstream side of the rotary conveyor surface is detached under the limitation of the second distance.

[0006] In some embodiments of the first aspect, the negative pressure conveyor includes: A rotatable rotating body has an inner cavity formed inside, and adsorption holes are distributed on the outer peripheral surface of the rotating body. The adsorption holes are connected to the inner cavity, and the outer peripheral surface of the rotating body constitutes the rotary conveying surface. The outer peripheral surface of the rotating body has multiple protrusions arranged laterally. A negative pressure system is provided, which is connected to the inner cavity. The negative pressure system is used to draw in the inner cavity to form a negative pressure zone on the outer circumferential surface of the rotating body.

[0007] In some embodiments of the first aspect, the rotating body further includes a wire mesh cage and a rotatable negative pressure suction roller, the wire mesh cage being arranged around the negative pressure suction roller, the wire mesh cage and the negative pressure suction roller being coaxially arranged, the outer surface of the wire mesh cage forming the rotary conveying surface, and the air inlet of the negative pressure suction roller being connected to the negative pressure system.

[0008] In some embodiments of the first aspect, the sidewalls on the upstream side and the corresponding side of the discharge port are arranged parallel to each other, the sidewall on the discharge port corresponding to the upstream side is an upper sidewall, the end of the upper sidewall is lower than the highest point of the upstream side, and the distance between the end of the upper sidewall and the upstream side is the first distance; further, the upper sidewall is movably arranged to be able to adjust the first distance.

[0009] In some embodiments of the first aspect, the sidewalls on the downstream side and the corresponding side of the discharge port are arranged parallel to each other, the sidewall on the discharge port corresponding to the downstream side is a lower sidewall, and the distance between the end of the lower sidewall and the downstream side is the second distance.

[0010] In some embodiments of the first aspect, the end of the upper sidewall is a pointed tip, and the end of the lower sidewall is a pointed tip.

[0011] In some embodiments of the first aspect, the bottom of the feeding hopper is provided with an air supply hole, which is in communication with the inner cavity of the hopper.

[0012] In some embodiments of the first aspect, the material handling assembly further includes a transition transfer member located downstream of the negative pressure conveyor along the conveying direction of the single-layer fabric sheet. The transition transfer member is used to receive and convey the single-layer fabric sheet processed by the negative pressure conveyor.

[0013] Secondly, embodiments of this application also provide a flexible fabric dismantling machine, which includes a material handling component as described in any of the above embodiments.

[0014] The embodiments of this application have the following advantages: This application provides a material handling assembly in which a negative pressure conveyor forms a negative pressure zone at the discharge port of the feed hopper on its rotary conveyor surface during operation. This negative pressure zone generates a continuous adsorption force. When layers of randomly stacked fabric sheets accumulate in the feed hopper and reach the discharge port, the one or more fabric sheets closest to the rotary conveyor surface are adsorbed by the negative pressure and adhere to the rotary conveyor surface. In the design, the first distance L1 between the upstream side of the rotary conveyor surface and the corresponding sidewall of the discharge port is strictly limited to between the thickness L of a single fabric layer and approximately the thickness 2L of two fabric layers. When the rotary conveyor surface, having adsorbed the fabric sheets, attempts to carry the fabric sheets away from the discharge port, this narrow channel (distance L1) acts as a forced screening mechanism. Theoretically, only a maximum of one fabric sheet is allowed to pass through this distance. The adsorption force of the negative pressure preferentially acts on the single fabric sheet closest to the conveyor surface, firmly gripping it. As this layer of fabric is pulled outward, the second layer of fabric that may be stuck or overlapped above it is effectively blocked and peeled off by the upstream hopper sidewall, thus ensuring that each successfully carried out and transferred is essentially a single layer of fabric. The rotary conveyor continues to operate, transporting the adsorbed single-layer fabric from the upstream side to the downstream side. Because the adsorption force in the negative pressure zone is uniformly distributed in the width direction, it ensures that the single-layer fabric is smoothly grasped and transported across the entire width of the conveyor surface, avoiding local accumulation or gaps, thereby achieving a uniform distribution of the fabric in the width direction.

[0015] Therefore, this technology achieves single-layer transfer of fabric sheets, solving the bottleneck of overlapping. Through a combination of sophisticated spacing design and negative pressure adsorption, it fundamentally solves the processing difficulties caused by the overlapping and adhesion of fabric sheets in the background technology. It forcibly separates multi-layered fabric sheets into single layers for transfer, providing an ideal material state for subsequent processes. Furthermore, it ensures uniform distribution of the fabric sheets across the width, and the negative pressure adsorption method can evenly grasp the fabric sheets across the entire width, avoiding the problems of excessive material in the middle, insufficient material at the edges, or localized clumping that may occur with traditional mechanical grasping or free-falling. This allows for uniform force distribution in subsequent needle punching or disassembly processes, resulting in better processing effects. Single-layer, uniformly distributed fabric sheets are a prerequisite for efficient and high-quality subsequent needle punching and flexible disassembly processes. For needle punching, single-layer fabric sheets are easier for needles to penetrate and entangle; for flexible disassembly, single-layer fabric sheets are subjected to uniform force, making it easier to loosen the fibers without damage. This component directly solves the bottleneck of upstream material supply, improving the efficiency of the entire production line and the quality of the finished product.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In the related technologies, there is a problem that urgently needs to be solved in the feeding part of the waste textile recycled fiber processing process: after the fabric pieces are fed into the hopper by air conveying or curtain conveying, the fabric pieces will be stacked in layers and disorderly, which will lead to processing difficulties due to the accumulation and adhesion of fabric pieces, and will not be conducive to subsequent needle punching and flexible disassembly.

[0026] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides a material handling component 100 for sorting stacked or wrinkled waste fabric pieces into a single layer, flat and continuously conveyed state.

[0027] The material handling assembly 100 includes a feeding hopper 110 and a negative pressure conveyor. The feeding hopper 110 has a discharge port. The negative pressure conveyor includes a rotatable conveying surface, at least partially located at the discharge port, and a negative pressure zone is formed in the portion of the conveying surface located at the discharge port. The conveying surface has an upstream side and a downstream side. The first distance 121 between the sidewalls of the upstream side and the corresponding side of the discharge port is L1. The thickness of the single-layer fabric is L, satisfying: L≤L1<2L. Through the operation of the negative pressure conveyor, under the constraint of the first distance 121, the upstream side of the conveying surface adsorbs and carries out the single-layer fabric.

[0028] In these embodiments, the feeding hopper 110 has a funnel-shaped structure that is wider at the top and narrower at the bottom, with a rectangular discharge port at the bottom for accommodating stacked waste fabric pieces (such as cut waste or garment fragments).

[0029] The negative pressure conveying component includes a rotatable conveying surface composed of a porous, breathable belt (such as a polyester fiber woven mesh belt with a pore size of 0.5 mm), wound between the driving and driven rollers and continuously rotated by a servo motor. At least part of the lower half of the conveying surface is located within the discharge port of the feed hopper 110, and a negative pressure chamber is provided below this area. The negative pressure chamber is connected to a vacuum fan via a pipe, creating a stable negative pressure adsorption zone in the area of ​​the conveying surface within the discharge port.

[0030] Crucially, a first gap 121 is formed between the upstream side of the rotary conveyor surface (i.e., the side closest to the fabric pile inside the feed hopper 110) and the corresponding side wall of the discharge port. Let the thickness of the single-layer fabric to be processed be L (e.g., L≈1.2mm for pure cotton knitted fabric). In this embodiment, L = 1.2 mm, therefore L1 is set to 1.5 mm. This gap is precisely controlled by adjusting the height limit plate of the discharge port.

[0031] When the stacked fabric pieces in the feed hopper 110 fall to the discharge port due to gravity, the bottom layer of fabric pieces comes into contact with the rotary conveyor surface. Due to the negative pressure adsorption, the rotary conveyor surface can only adsorb and move the bottom single-layer fabric piece that is in direct contact with it upstream. The second and subsequent layers of fabric pieces are physically restricted by the distance L1 between the discharge port sidewall and the rotary conveyor surface (L1 is less than 2L, which is insufficient to accommodate two layers of fabric pieces passing through simultaneously), and are thus effectively blocked from entering the adsorption zone. This achieves automatic single-layer separation and stable output, avoiding uneven disassembly or equipment jamming caused by multiple layers of fabric pieces entering the subsequent needle punching components at the same time.

[0032] In some embodiments, each section of the rotary conveyor surface is formed with a negative pressure zone, and the second distance 122 between the sidewalls on the downstream side and the corresponding side of the discharge port is L2, satisfying: 0≤L2<L, so that the single-layer fabric adsorbed on the downstream side of the rotary conveyor surface is detached under the constraint of the second distance 122 when the negative pressure conveyor is running.

[0033] In these embodiments, negative pressure chambers are provided along the entire running path of the rotary conveyor surface (including the section located in the discharge port and its downstream extension), or a segmented negative pressure control system is used to enable each segment of the rotary conveyor surface to form a negative pressure zone, but the local negative pressure intensity can be dynamically adjusted according to process requirements.

[0034] When the rotary conveyor surface with a single layer of fabric adsorbed on it moves to the downstream side of the discharge port (i.e., the side away from the fabric pile and towards the needle punching assembly), a second gap 122 is formed between it and the corresponding side wall of the discharge port.

[0035] In this embodiment, the gap between the rotary conveyor surface and the sidewall is smaller than the thickness of the single-layer fabric. When the fabric moves to this area with the conveyor surface, its edges are slightly squeezed or scraped by the sidewall. Simultaneously, although negative pressure adsorption still exists in this area, the limited physical gap prevents the fabric from completely adhering to the conveyor surface, leading to localized airtightness disruption and a significant decrease in negative pressure adsorption. The combined effect of these two factors causes the single-layer fabric to automatically detach from the rotary conveyor surface upon reaching the downstream end, smoothly transitioning to the subsequent conveyor belt or directly into the needle-punching assembly.

[0036] Optionally, to further ensure the reliability of separation, a local negative pressure shut-off valve can be installed on the discharge port side (such as using baffle partitions to form negative pressure on the hopper side and no negative pressure on the discharge port side) or the negative pressure can be weakened. However, even without active control, effective separation can be achieved by relying solely on mechanical constraints or gravity.

[0037] In some embodiments, the negative pressure conveying component includes a rotatable rotating body 120 and a negative pressure system. The rotating body 120 has an inner cavity 125, and its outer peripheral surface has suction holes that communicate with the inner cavity 125. The outer peripheral surface of the rotating body 120 forms a rotating conveying surface. Multiple protrusions are laterally arranged on the outer peripheral surface of the rotating body. The negative pressure system communicates with the inner cavity 125 and is used to draw suction from the inner cavity 125 to form a negative pressure zone on the outer peripheral surface of the rotating body 120.

[0038] In these embodiments, the rotating body 120 is a horizontally arranged cylindrical roller. The rotating body 120 has a closed inner cavity 125, and its outer circumferential surface is evenly distributed with multiple adsorption holes, which are through holes. These adsorption holes communicate with the inner cavity 125, so that when the inner cavity 125 is under negative pressure, adsorption force can be generated at various points on the outer circumferential surface. This outer circumferential surface constitutes the rotary conveying surface.

[0039] The negative pressure system includes a vacuum blower and a rotary sealing joint. The vacuum blower is connected to the rotary sealing joint via a pipe. The rotary sealing joint is installed at one end of the shaft of the rotating body 120, achieving a dynamic airtight connection of the inner cavity 125 during rotation. Thus, the negative pressure system can continuously draw air from the inner cavity 125, forming a continuous and uniform negative pressure zone on the entire outer circumference of the rotating body 120.

[0040] The rotating body 120 is driven by a servo motor via a synchronous belt, and the speed is adjustable to adapt to different fabric types.

[0041] In this embodiment, by adjusting the bottom height of the feeding hopper 110, when the stacked fabric pieces fall into the discharge port, the bottom layer of fabric pieces is attracted by the negative pressure of the outer circumference of the rotating body 120 and is carried upstream as it rotates; while the second and above layers of fabric pieces are effectively blocked because they cannot pass through the gap at the same time, thereby achieving high-precision single-layer output.

[0042] When the rotating body 120 rotates to the downstream side (i.e., the side away from the fabric pile and facing the needle punching assembly), a second gap 122 is formed between its outer peripheral surface and the corresponding sidewall of the discharge port. Since this gap is smaller than the thickness of a single layer of fabric, when the rotating body 120 with the fabric adsorbed runs to this area, the edge of the fabric is slightly squeezed by the sidewall, causing it to locally lift up, breaking the seal between it and the adsorption hole, and causing the negative pressure adsorption force to drop sharply. Although the inner cavity 125 still maintains negative pressure, due to the failure of airtightness, the fabric automatically detaches from the outer peripheral surface of the rotating body 120 under the action of gravity and subsequent tension, and smoothly enters the downstream conveying channel.

[0043] It should be noted that the outer circumference of the rotating body is decorated with 4 to 10 protrusions to agitate the cloth pieces in the hopper, overcome the adhesion between the cloth pieces, increase the friction of the rotating body surface, and improve the negative pressure adsorption effect.

[0044] In some embodiments, the rotating body 120 further includes a mesh cage 124 and a rotatable negative pressure suction roller 123. The mesh cage 124 is arranged around the negative pressure suction roller 123. The mesh cage 124 and the negative pressure suction roller 123 are coaxially arranged. The outer surface of the mesh cage 124 forms a rotary conveying surface. The air inlet of the negative pressure suction roller 123 is connected to the negative pressure system.

[0045] In these embodiments, the negative pressure suction roller 123 is supported on the frame by bearings and is driven by a servo motor to rotate about its central axis. A rotary sealing joint is installed at one end of its shaft, which is connected to the negative pressure system, so that the air inlet can continuously draw in external gas during rotation.

[0046] The mesh cage 124 is a cylindrical porous structure made of woven stainless steel wire or rolled perforated steel plate to ensure high air permeability and prevent clogging by fine fibers. The mesh cage 124 is arranged around the outside of the negative pressure suction roller 123, and the two are coaxially arranged. The mesh cage 124 rotates while the negative pressure suction roller 123 remains stationary.

[0047] The outer surface of the mesh cage 124 forms the rotary conveying surface, which is used to directly contact and adsorb the fabric. When the negative pressure system is started, air enters the inner cavity 125 of the mesh cage 124 through the pores, and is then sucked out through the air inlet on the negative pressure suction roller 123, thereby forming a uniform negative pressure zone on the outer surface of the mesh cage 124 to achieve the adsorption and conveying of the fabric.

[0048] In some embodiments, the sidewalls on the upstream side and the corresponding side of the discharge port are arranged parallel to each other. The sidewall on the discharge port corresponding to the upstream side is the upper sidewall, and the lowest point of the upper sidewall is lower than the highest point of the upstream side. The distance between the lowest point of the upper sidewall and the upstream side is a first distance 121. The sidewalls on the downstream side and the corresponding side of the discharge port are arranged parallel to each other. The sidewall on the discharge port corresponding to the downstream side is the lower sidewall, and the distance between the end of the lower sidewall and the downstream side is a second distance 122.

[0049] The bottom of the feed hopper 110 is provided with a rectangular discharge port, which has clearly defined upper and lower side walls along the conveying direction. The wire mesh cage 124 is horizontally arranged inside the discharge port, with its axis perpendicular to the conveying direction. The wire mesh cage 124 is driven by a servo motor to rotate continuously, so that its first half circumference (facing the fabric pile) is the upstream side and the second half circumference (facing the needle punching assembly) is the downstream side.

[0050] The upper sidewall is located at the top of the discharge port, corresponding to the upstream side of the rotating body 120. The upper sidewall is a horizontal or slightly inclined plane, and its lowest point (i.e. the position closest to the wire mesh cage 124) is lower than the highest point of the upstream side (i.e. the outer circle vertex of the wire mesh cage 124 on the upstream side).

[0051] The lower sidewall is located at the bottom of the discharge port, corresponding to the downstream side of the rotating body 120. The lower sidewall is parallel to the outer circular contour of the downstream side (usually a horizontal plane), forming a second distance 122 between them.

[0052] In some embodiments, the end of the upper sidewall is a pointed tip, and the end of the lower sidewall is a pointed tip.

[0053] In these embodiments, the discharge port at the bottom of the feed hopper 110 is provided with an upper sidewall and a lower sidewall along the conveying direction, corresponding to the upstream and downstream sides of the negative pressure conveying component, respectively.

[0054] Crucially, the ends of the upper and lower sidewalls are both pointed structures. The pointed end refers to the edge of the sidewall facing the rotating body 120 being machined into an acute angle or a small radius rounded corner, specifically in any of the following forms: a cutting edge (angle ≤ 30°), a rounded transition (radius R ≤ 0.5 mm), or a chamfered edge (chamfer size 0.3–0.8 mm).

[0055] The tip of the upper sidewall is located at the measurement reference point of the first spacing 121, directly opposite the highest point on the upstream side of the mesh cage 124. When the fabric is attracted by the mesh cage 124 and carried upstream, its upper edge must slide under the upper sidewall. The tip structure allows the fabric to slide off the sidewall without obstruction, preventing multiple layers from being mis-fed due to jamming at the edges.

[0056] The tip of the lower sidewall is located at the measurement reference point of the second spacing 122, directly opposite the lowest point on the downstream side of the mesh cage 124. When the fabric detaches from the mesh cage 124 on the downstream side, its lower edge will lightly touch the lower sidewall. The tip design ensures that the fabric slides smoothly, avoiding the accumulation of short fibers or the formation of wrinkles at the right-angled edges.

[0057] In some embodiments, the upper sidewall can rotate about one end of a pin, and the position of the other end can change the first spacing to accommodate different material thicknesses.

[0058] In some embodiments, the bottom of the feed hopper 110 is provided with an air supply hole, which is connected to the inner cavity 125 of the hopper.

[0059] In other words, the bottom of the lower side wall is provided with an air supply hole, which can effectively optimize the airflow state inside the feed hopper 110, provide a more suitable airflow environment for the mesh cage 124 to adsorb the cloth sheet, and thus ensure the stability and efficiency of the adsorption process.

[0060] In some embodiments, the material handling assembly 100 further includes a transition transfer member located downstream of the negative pressure conveyor along the conveying direction of the single-layer fabric sheet. The transition transfer member 200 is used to receive and convey the single-layer fabric sheet processed by the negative pressure conveyor 200.

[0061] In these embodiments, the transition transfer component is a conveyor curtain, which consists of a conveyor curtain, a front guide roller, and a rear guide roller. Its main function is to receive the fabric pieces transferred by negative pressure adsorption and to smoothly and continuously transport the fabric pieces to the next process, ensuring that the fabric pieces remain flat during the transfer process and providing a stable material supply for subsequent processing.

[0062] In some embodiments, this application also provides a flexible fabric dismantling machine, which includes a material handling component 100 as described in any of the above embodiments.

[0063] Since the material handling component 100 has the above-mentioned technical effects, the flexible fabric disassembly machine including the material handling component 100 should have the same technical effects, which will not be elaborated here.

[0064] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0065] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
