Description

Technical Field

[0001] The invention relates to the technical field of cotton wool recovery equipment, and in particular to a textile cotton wool recovery device. Background Art

[0002] Belly cotton is a byproduct of the textile manufacturing process. It primarily originates from the removal of impurities and neps from raw cotton by equipment like blowrooms and carding machines. Belly cotton primarily consists of a mixture of short fibers, neps, and a small amount of impurities, and is considered textile waste. In actual production, belly cotton typically forms irregular, large clumps.

[0003] In existing technologies, large, irregular clumps of cotton wool from the belly of a car can instantly clog the lint recovery device's suction port, requiring the lint recovery device to be shut down and manually cleared.

[0007] Optionally, the driving disk includes a first driving member, a disk body and a hinge column, the output end of the first driving member is coaxially connected to the disk body to drive the disk body to rotate, the hinge column is arranged on the edge of the disk body, and one end of the first connecting rod is rotatably mounted on the hinge column.

[0008] Optionally, the second cleaning member includes a second driving member, a third driving member, a cleaning rod and several breaking pieces, the output end of the second driving member is connected to the third driving member to drive the third driving member to insert or withdraw from the insertion hole along the radial direction of the cleaning section, the output end of the third driving member is coaxially connected to the cleaning rod to drive the cleaning rod to rotate along its axial direction, the outer surface of the cleaning rod is recessed inward to form several mounting cavities, several of the mounting cavities are arranged at intervals along the circumference of the cleaning rod, and several breaking pieces are rotatably mounted in the mounting cavities, and the breaking pieces are configured to be completely accommodated in the mounting cavity when passing through the insertion hole and to protrude from the cleaning rod when the cleaning rod rotates.

[0009] Optionally, a plurality of breaking pieces are provided in each of the installation cavities, and the plurality of breaking pieces are arranged in the installation cavity at intervals along the axial direction of the clearing rod.

[0010] Optionally, the breaking piece includes an interconnected mounting portion and a breaking portion, the mounting portion being rotatably mounted in the mounting cavity, and the mounting portion being completely accommodated in the mounting cavity when the breaking piece passes through the insertion through hole and when the clearing rod rotates, the breaking portion being completely accommodated in the mounting cavity when the breaking piece passes through the insertion through hole, and being completely accommodated in the mounting cavity when the clearing rod rotates, the breaking portion being located outside the mounting cavity and protruding from the clearing rod.

[0011] Optionally, the broken portion is formed into any one of the following shapes: a conical structure, a triangular pyramid structure, or a triangular columnar structure.

[0013] Optionally, the control unit is electrically connected to the first cleaning member and the second cleaning member to control the operating states of the first cleaning member and the second cleaning member.

[0014] Beneficial effects: 1. Through the above technical solution, the textile lint recovery device of the present invention can effectively prevent and alleviate inlet blockage. Specifically, the radial dimension of the first inlet section gradually decreases, forming a converging channel, which helps guide and gather irregular, large clumps of cotton wool toward the removal section. The radial dimension of the second inlet section gradually increases, forming a diverging channel, which helps restore airflow or reduce flow rate behind the removal section, reducing the risk of downstream blockage. The key design is the removal section, which is configured as an independent annular structure with an inner diameter that is the same as the minimum inner diameter of the first and second inlet sections. This means that under normal operating conditions, the inner wall of the removal section smoothly connects with the minimum inner diameter of the inlet section, ensuring the continuity of the airflow channel and minimal resistance, allowing airflow and lint to pass smoothly. Furthermore, the outer diameter of the removal section is larger than the minimum outer diameter of the first and second inlet sections. This provides a structural basis for the movement of the removal section itself (driven by the first removal member) without immediately disrupting the integrity of the suction port, ensuring the continued suction effect of the suction port.

[0015] Second, the present invention enables online unclogging without stopping the machine. When cotton accumulates within the tapering first inlet section and becomes or threatens to become blocked in the cleaning section, the first cleaning element is activated, driving the cleaning section to move radially along the first inlet section. This radial movement (which produces vibration, swaying, or a small degree of expansion and contraction) directly impacts the cotton clumps clogged in the cleaning section. This mechanical disturbance can loosen, break up, or displace the clogged cotton clumps, allowing them to resume flow or be drawn in.

[0016] Third, for stubborn blockages that are difficult to completely loosen by radial movement of the cleaning section alone, the present invention also provides a second cleaning piece as a more proactive means of intervention. Specifically, the cleaning section is provided with an insertion hole extending along its radial direction, so as to allow the second cleaning piece to enter the location where the blockage occurs inside the cleaning section. The second cleaning piece is configured to be able to extend into the interior of the cleaning section through this insertion hole. Once inserted, its core function is to directly destroy the blocked car belly cotton ball. The destruction operation is also carried out when the device is in operation (suction). The second cleaning piece extends into the core area of ​​the blockage and physically decomposes the large cotton balls into smaller fragments through its own structure (the specific destruction method can be cutting, stirring, etc.). These small fragments are more easily carried away by the airflow, thereby completely clearing the blockage.

[0017] In summary, the present invention utilizes a unique three-stage suction port structure (particularly a radially movable annular cleaning section) and a two-stage cleaning mechanism (a first cleaning member drives the cleaning section to move radially and disturb it, while a second cleaning member inserts into a through hole and extends into the interior to physically damage it). This allows for the effective prevention, mitigation, and removal of blockages at the suction port caused by irregular, large clumps of cotton wool, without stopping the equipment. This effectively addresses the key pain points mentioned in the background art, namely, "inconvenient cleaning" and "resulting in shutdown of the cotton wool recovery device and low cotton wool recovery efficiency," significantly improving the continuity and efficiency of cotton wool recovery.

DETAILED DESCRIPTION

[0022] First, it should be noted that the textile lint recovery device of the present invention is an improvement over existing lint recovery devices. The present invention will not elaborate on the structures and processes known in the prior art, such as negative pressure generation and lint collection. The main improvement of the present invention lies in the suction port structure of existing lint recovery devices.

[0023] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, the present invention provides a textile cotton recycling device 100, including a suction port 1, a first cleaning member 2 and a second cleaning member 3. The suction port 1 includes a first inlet section 11, a cleaning section 12 and a second inlet section 13 connected in sequence. In the direction from the first inlet section 11 to the second inlet section 13, the radial size of the first inlet section 11 gradually decreases, and the radial size of the second inlet section 13 gradually increases. The cleaning section 12 is set to an annular structure, and the inner diameter of the cleaning section 12 is the same as the minimum inner diameter of the first inlet section 11 and the second inlet section 13. The outer diameter of the cleaning section 12 is larger than the minimum outer diameter of the first inlet section 11 and the second inlet section 13. The first cleaning member 2 is connected to the cleaning section 12 to drive the cleaning section 12 to move radially along the first inlet section 11. The cleaning section 12 is provided with an insertion hole 121 extending radially thereof. The second cleaning member 3 is configured to be able to extend into the cleaning section 12 through the insertion hole 121 and be used to destroy the cotton in the belly.

[0025] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present invention, the working process / working principle of the above-mentioned implementation method is first described below.

[0026] When the suction port 1 is clogged, due to the variable diameter design of the first inlet section 11 and the second inlet section 13, the blockage of the cotton wool in the suction port 1 will only occur in the cleaning section 12 with the smallest inner diameter. At this time, the first cleaning member 2 can be activated, so that the first cleaning member 2 drives the cleaning section 12 to move radially in the first inlet section 11, thereby acting on the cotton wool mass blocked in the cleaning section 12, mechanically disturbing it, and loosening, breaking or displacing the blocked cotton wool mass, so that it can resume flow or be sucked in. At the same time, the second cleaning member 3 can be inserted into the cleaning section 12 along the insertion hole 121 to destroy the blocked cotton wool mass, further ensuring that it can resume flow or be sucked in.

[0027] Through the above technical solution, first, the textile cotton wool recovery device 100 of the present invention can effectively prevent and alleviate the inlet blockage. Specifically, first, the radial dimension of the first inlet section 11 gradually decreases to form a tapered channel, which helps to guide and gather irregular large-lump-shaped cotton wool to flow to the cleaning section 12. The radial dimension of the second inlet section 13 gradually increases to form a gradually expanding channel, which helps to restore the airflow or reduce the flow rate behind the cleaning section 12, reducing the risk of downstream blockage. The most critical thing is the design of the cleaning section 12, which is set to an independent annular structure, and its inner diameter is the same as the minimum inner diameter of the first inlet section 11 and the second inlet section 13. This means that under normal working conditions, the inner wall of the cleaning section 12 is smoothly connected with the minimum inner diameter of the inlet section, ensuring the continuity and minimum resistance of the airflow channel, and the airflow and cotton wool can pass smoothly. At the same time, the outer diameter of the cleaning section 12 is larger than the minimum outer diameter of the first inlet section 11 and the second inlet section 13. In this way, a structural basis is provided for the movement of the cleaning section 12 itself (driven by the first cleaning member 2 ) without immediately destroying the integrity of the suction port 1 , thereby ensuring the continuity of the suction effect of the suction port 1 .

[0028] Second, the present invention enables non-stop online unclogging. When cotton accumulates within the tapering first inlet section 11 and becomes or threatens to become blocked in the cleaning section 12, the first cleaning element 2 is activated, driving the cleaning section 12 radially along the first inlet section 11. This radial movement (which results in vibration, swaying, or a small degree of expansion and contraction) directly impacts the cotton clumps clogged in the cleaning section 12. This mechanical disturbance can loosen, break up, or displace the clogged cotton clumps, allowing them to resume flow or be drawn in.

[0029] Third, for stubborn blockages that are difficult to completely loosen by the radial movement of the cleaning section 12 alone, the present invention also provides a second cleaning member 3 as a more proactive means of intervention. Specifically, the cleaning section 12 is provided with an insertion hole 121 extending along its radial direction, so as to allow the second cleaning member 3 to enter the position where the blockage occurs inside the cleaning section 12. The second cleaning member 3 is configured to be able to extend into the interior of the cleaning section 12 through this insertion hole 121. Once inserted, its core function is to directly destroy the blocked car belly cotton balls. The destruction operation is also carried out when the device is in operation (suction). The second cleaning member 3 extends into the core area of ​​the blockage and physically decomposes the large cotton balls into smaller fragments through its own structure (the specific destruction method can be cutting, stirring, etc.). These small fragments are more easily carried away by the airflow, thereby completely clearing the blockage.

[0030] In general, the present invention utilizes a unique three-stage suction port 1 structure (particularly the radially movable annular cleaning section 12) and a two-stage cleaning mechanism (a first cleaning member 2 drives the cleaning section 12 to move radially and disturb it, while a second cleaning member 3 extends into the interior through a through hole 121 to physically damage it). This allows the present invention to effectively prevent, alleviate, and clear blockages at the suction port 1 caused by irregular, large, and lumpy cotton wool without stopping the equipment. This effectively addresses the key pain points of "inconvenient cleaning" and "causing the cotton wool recovery device to shut down and resulting in low cotton wool recovery efficiency" mentioned in the background art, significantly improving the continuity and efficiency of cotton wool recovery.

[0031] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the first cleaning member 2 of the present invention may include a driving disk 21, a first connecting rod 22, a second connecting rod 23 and a limit block 24, one end of the first connecting rod 22 is hinged to the edge of the driving disk 21, the other end of the first connecting rod 22 is hinged to the second connecting rod 23, the end of the second connecting rod 23 away from the first connecting rod 22 is connected to the cleaning section 12, the second connecting rod 23 is arranged along the radial direction of the cleaning section 12, and the limit block 24 is provided with a limit groove 241 extending along the radial direction of the cleaning section 12, and the second connecting rod 23 is accommodated in the limit groove 241.

[0032] Through this embodiment, first, a reliable and controllable radial drive can be provided. Specifically, this embodiment adopts a mechanical linkage mechanism consisting of a drive disc 21, a first connecting rod 22, a second connecting rod 23 and a limit block 24. Among them, the drive disc 21 serves as the power input point, and its rotational motion (whether directly driven by the motor or through other transmissions) is the starting point of the entire driving process. One end of the first connecting rod 22 is hinged to the edge of the drive disc 21, and the other end is hinged to the second connecting rod 23. This design cleverly converts the rotational motion of the drive disc 21 into an approximate linear motion of the second connecting rod 23. The second connecting rod 23 is directly connected to and drives the cleaning section 12, and its direction is set to be along the radial direction of the cleaning section 12. This ensures that the driving force is effectively and correctly transmitted to the cleaning section 12, so that it moves strictly along the required radial path (for example, vibrating, reciprocating or impacting).

[0033] Second, it can ensure the accuracy and stability of the direction of movement. Specifically, in this embodiment, the limiting groove 241 is explicitly designed to extend in the radial direction of the clearing section 12. The second connecting rod 23 is accommodated in this limiting groove 241. This means that the limiting groove 241 plays a forced guiding and restraining role on the movement of the second connecting rod 23. In this way, no matter how the driving disc 21 rotates, the movement transmitted by the connecting rod, the second connecting rod 23 can only move on the straight path defined by the limiting groove 241, that is, strictly along the radial direction of the clearing section 12. It can effectively avoid the risk of the second connecting rod 23 being offset, swinging or stuck during movement, ensuring that the radial movement of the clearing section 12 is highly accurate, stable and reliable. This is crucial for effectively disturbing or loosening blockages, and avoids mechanism failure or damage to the structure of the suction port 1 due to deviation in the motion trajectory.

[0034] Third, it enables efficient motion conversion. Specifically, the four-bar mechanism (drive disc 21 - first connecting rod 22 - second connecting rod 23 - limiting slot 241) of this embodiment efficiently converts the continuous rotational motion of the drive disc 21 into the linear reciprocating motion (radial movement) required by the clearing section 12. This conversion structure is relatively simple, offers high transmission efficiency, and fast response, making it suitable for blockage clearing scenarios requiring rapid, repetitive motion.

[0035] Furthermore, in this embodiment, the output force and potential travel range can be adjusted by varying the rod length or hinge point location. Specifically, by designing the dimensions of the drive disc 21, the connecting rod length, and the hinge point location on the drive disc 21, the force imparted to the cleaning section 12 and the radial movement amplitude (travel) thereof can be optimized to accommodate varying blockage severity or equipment models, enhancing the device's adaptability and cleaning effectiveness.

[0036] In one embodiment of the present invention, Figure 1 and Figure 3As shown, the driving disk 21 of the present invention includes a first driving member 211, a disk body 212 and a hinge column 213. The output end of the first driving member 211 is coaxially connected to the disk body 212 for driving the disk 21 body to rotate. The hinge column 213 is arranged on the edge of the disk body 212, and one end of the first connecting rod 22 is rotatably mounted on the hinge column 213.

[0037] Through this embodiment, first, a direct, efficient and reliable motive force input can be provided. Specifically, the design of the coaxial connection between the output end of the first driving member 211 and the disk body 212 means that the power transmission is direct and efficient. The rotational output of the first driving member 211 directly drives the disk 21 body to rotate with almost no offset or angular loss. It can avoid the problems of slippage, wear, energy loss or reduced precision that may be caused by the use of intermediate transmission mechanisms such as belts, chains or gears, ensuring that the driving disk 21 obtains a stable, reliable and controllable motive force. This is crucial for the need to accurately control the timing, frequency and amplitude of the radial movement of the cleaning section 12.

[0038] Second, it enables a precise and low-friction hinged connection. Specifically, first, placing the hinge point (hinge post 213) at the maximum lever arm (edge) of the disk body 212 maximizes the travel output of the drive disk 21's rotational motion on the connecting rod (at the same disk rotation angle, the edge hinge point moves the greatest linear distance, thereby driving the cleaning section 12 to a greater radial distance). Second, it ensures that the connection between the first connecting rod 22 and the hinge post 213 is a low-friction revolute pair. This not only reduces motion resistance and improves energy transfer efficiency, but also reduces wear, ensuring the smooth and reliable long-term operation of the mechanism.

[0039] In one embodiment of the present invention, Figure 1 、 Figures 4 to 6 As shown, the second cleaning member 3 of the present invention may include a second driving member 31, a third driving member 32, a cleaning rod 33 and a plurality of breaking pieces 34. The output end of the second driving member 31 is connected to the third driving member 32 to drive the third driving member 32 to insert or withdraw from the insertion hole 121 along the radial direction of the cleaning section 12. The output end of the third driving member 32 is coaxially connected to the cleaning rod 33 to drive the cleaning rod 33 to rotate along its axial direction. The outer surface of the cleaning rod 33 is recessed inward to form a plurality of mounting cavities 331. The plurality of mounting cavities 331 are arranged at intervals along the circumference of the cleaning rod 33. The plurality of breaking pieces 34 are rotatably mounted in the mounting cavity 331. The breaking piece 34 is configured to be completely accommodated in the mounting cavity 331 when passing through the insertion hole 121 and to protrude from the cleaning rod 33 when the cleaning rod 33 rotates.

[0040] First, this embodiment provides efficient, active physical destruction capabilities. Specifically, when inserted through the through-hole 121, the rupture disc 34 is completely contained within the mounting cavity 331. This minimizes the radial dimension (diameter) of the entire cleaning rod 33, including the rupture disc 34, when passing through the narrow insertion through-hole 121. This prevents the rupture disc 34 from scraping, colliding, or getting stuck against the inner wall of the insertion through-hole 121 during insertion and withdrawal, ensuring smooth and reliable insertion and withdrawal, and protecting components. When the cleaning rod 33 rotates, the rupture disc 34 protrudes from the cleaning rod 33. Specifically, when the cleaning rod 33 rotates, the rupture disc 34 is flung out of the mounting cavity 331 under the action of centrifugal force, exposing its rupture portion 342. These protruding rupture discs 34 act like "rotating blades" or "stirring teeth," rotating at high speed to impact, cut, tear, or agitate the large clumps of cotton wool clogged within the cleaning section 12, physically breaking them into smaller fragments. This is far more effective than simple agitation by the rod itself.

[0041] Second, it optimizes space utilization and destructive strength. Specifically, the circumferential spacing of the mounting cavities 331 ensures that the rupture discs 34 protrude evenly in the circumferential direction as the clearing rod 33 rotates, creating a multi-point, balanced destructive force. This prevents excessive or unbalanced force at a single point, improving destructive efficiency and rod stability. Furthermore, the rotatable mounting of the rupture discs 34 allows them to retract when passing through the through-hole and protrude during rotation. Furthermore, they maintain a certain degree of freedom of movement in the protruding state, enabling them to better adapt to and produce a stronger impact / cutting effect when striking cotton wool, potentially reducing damage from hard collisions.

[0042] Third, the combination of insertion and rotation enables efficient clearing. Specifically, the second drive member 31 controls the clearing rod 33 to be radially inserted into the core of the blockage, and the third drive member 32 drives the inserted clearing rod 33 to rotate at high speed. The rotating clearing rod 33 drives the protruding breaking piece 34 to forcefully destroy the blockage. In this way, through the combined action of "first precise positioning and insertion, then high-speed rotation and destruction", the destructive effect is directly applied to the most severely clogged area, greatly improving the efficiency and thoroughness of unblocking. After the destruction is completed, the second drive member 31 can retract the clearing rod 33, and the device continues its normal suction operation.

[0043] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, a plurality of breaking pieces 34 are disposed in each installation cavity 331 of the present invention. The plurality of breaking pieces 34 are spaced apart in the installation cavity 331 along the axial direction of the clearing rod 33 .

[0044] Thus, in this embodiment, firstly, the multiple breaking pieces 34 are distributed at different axial positions, ensuring that when the clearing rod 33 rotates, the breaking force is applied more evenly along the axial direction to the clogged object, avoiding inadequate destruction in localized areas. Secondly, the densely distributed axial breaking pieces 34 form a continuous or dense three-dimensional "breaking surface" in their protruding state, which more effectively tears and shatters large axially extending or deep-seated clogged cotton fibers, significantly improving the efficiency and thoroughness of a single clearing operation.

[0045] In one embodiment of the present invention, Figure 6 As shown, the breaking piece 34 of the present invention includes a mounting portion 341 and a breaking portion 342 that are connected to each other. The mounting portion 341 is rotatably mounted in the mounting cavity 331. When the breaking piece 34 passes through the insertion hole 121 and when the clearing rod 33 rotates, the mounting portion 341 is completely accommodated in the mounting cavity 331. When the breaking piece 34 passes through the insertion hole 121, the breaking portion 342 is completely accommodated in the mounting cavity 331. When the clearing rod 33 rotates, the breaking portion 342 is located outside the mounting cavity 331 and protrudes from the clearing rod 33.

[0046] In this embodiment, first, the mounting portion 341 remains completely contained within the mounting cavity 331, providing a stable pivot point for the breaker 34 and preventing it from shifting or falling out. Second, the breaker portion 342 protrudes outside the mounting cavity 331 during rotation, fully exposing its structure and directly engaging obstructions, thereby enhancing cutting and tearing strength. Finally, when inserted through the through-hole 121, the breaker portion 342 fully retracts into the mounting cavity 331, completely eliminating the risk of interference with the hole wall, protecting the component, and ensuring smooth operation.

[0047] In one embodiment of the present invention, the breaking portion 342 of the present invention is formed into any one of the following shapes: a conical structure, a triangular pyramid structure, or a triangular prism structure. When the breaking portion 342 is formed into a conical structure, its tip facilitates piercing the cotton ball, thereby dispersing stress and improving wear resistance. When the breaking portion 342 is formed into a triangular pyramid shape, its edge structure can enhance tearing ability, taking into account both penetration depth and structural strength. When the breaking portion 342 is formed into a triangular prism shape, the large contact surface achieves strong cutting and crushing, making it suitable for high-density blockages.

[0048] In one embodiment of the present invention, the textile cotton lint recovery device 100 of the present invention also includes a first pressure sensor, a second pressure sensor and a control unit. The first pressure sensor is arranged in the first inlet section 11, and the second pressure sensor is arranged in the second inlet section 13. The first pressure sensor and the second pressure sensor are electrically connected to the control unit respectively.

[0049] In this embodiment, by respectively arranging the first pressure sensor and the second pressure sensor at the first inlet section 11 and the second inlet section 13, two monitoring points across the blockage risk area can be formed. In this way, the control unit can accurately judge the blockage situation by using the pressure difference change of the two monitoring points to assist manual judgment or correction.

[0050] In one embodiment of the present invention, a control unit is electrically connected to the first and second cleaning elements 2 and 3 to control their operational states. This allows for automatic triggering of cleaning actions based on pressure data from the first and second pressure sensors. (For example, when a blockage is imminent, for example, if the pressure data from the second pressure sensor increases abnormally, only the first cleaning element 2 is activated to initiate a disturbance; when a blockage is severe, for example, if the pressure data from the first pressure sensor drops sharply, both the first and second cleaning elements 2 and 3 are activated simultaneously.) This achieves a closed technical loop of "perception → decision → execution," eliminating the need for human intervention throughout the entire process and improving the efficiency of continuous equipment operation.

[0051] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
