Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and more specifically, to a device for uniformly combing and laying polyester PET warp and weft woven fabric. Background Technology

[0002] Polyester PET (polyethylene terephthalate) fiber is one of the world's most produced and widely used chemical fibers, and is widely used in the production of nonwoven fabrics. In the nonwoven fabric production process, carding and web laying are the core steps that determine the quality of the final product. The carding machine combs the opened PET short fibers into a uniform thin web, and the web laying machine then folds and lays the thin web into a multi-layer fiber web of the required thickness and width for subsequent reinforcement processes such as needle punching, hot rolling, or hydroentangling.

[0003] However, to address the static electricity problem of PET fibers, some existing equipment incorporates a humidifying mechanism. This mechanism sprays water mist onto the fiber web surface to provide micro-humidification, increasing the fiber's moisture regain and reducing surface resistance, thereby eliminating static electricity. However, existing humidifying devices have the following shortcomings in practical use: Most existing humidifying devices use multiple nozzles to spray simultaneously onto the fiber web surface. When multiple nozzles operate simultaneously, the spray cones from adjacent nozzles collide spatially, merging to form large bubbles or droplets, resulting in increased water mist particle size and uneven distribution. These large bubbles or droplets, when they fall onto the fiber web surface, cause localized over-wetting, forming water stains or wet spots. This not only affects the uniformity of the fiber web but may also lead to deformation or adhesion during subsequent conveying. Furthermore, PET fibers generate a large amount of short fibers, lint, and dust during carding and conveying. These fly filaments easily fall and adhere to the nozzle openings. After prolonged operation, these lint gradually accumulate at the nozzle openings, causing partial or complete blockage. When the nozzles become clogged, the spray volume decreases and the spray angle changes, further exacerbating the uneven wetting of the fiber web surface.

[0004] Meanwhile, the fiber web output by the carding machine is thin and has a loose structure. During the process of being transferred from the output end of the carding machine to the input end of the web laying machine, it is easily affected by the airflow disturbance in the workshop, equipment vibration and static electricity, resulting in problems such as drifting, edge turning, wrinkling or stretching deformation.

[0005] Therefore, a device for uniformly combing and laying polyester PET warp and weft woven fabric is proposed to address the above problems. Summary of the Invention

[0018] The technical effects and advantages of this application are as follows:

[0019] Compared with existing technologies, this polyester PET woven fabric uniform carding and web laying device sprays micron-level water mist onto the fiber web surface through a cotton-lubricating mechanism to increase the moisture regain of PET fibers, reduce surface resistance, effectively eliminate static electricity, and avoid fiber entanglement and defects such as "neps" and "cloud spots," significantly improving carding uniformity. Simultaneously, the connecting sleeve of the cotton-lubricating mechanism is mechanically linked to the fixed rod of the moving mechanism via a first belt, ensuring that the spraying rhythm is synchronized with the speed of the web conveyor, guaranteeing the continuity and stability of the wetting effect. Furthermore, multiple sets of water outlets on the surface of the connecting sleeve are arranged circumferentially. The alternating arrangement of multiple nozzles allows them to work in cycles without simultaneous activation, effectively avoiding the problem of adjacent spray cones colliding and merging into large bubbles or droplets when spraying simultaneously with traditional multiple nozzles. This ensures that each droplet flies independently and evenly onto the fiber surface, significantly improving coating uniformity and preventing localized over-wetting that could lead to water stains or wet spots. Furthermore, when a set of nozzles is in a resting state, compressed air is sprayed through the air pipe through the air hole to dry the nozzle opening, removing residual liquid and attached lint. This greatly reduces clogging caused by lint adhesion, minimizing the frequency of manual cleaning and equipment downtime.

[0020] Compared with existing technologies, this polyester PET warp and weft woven fabric uniform carding and web laying device, through an adsorption mechanism, forms a uniform negative pressure adsorption force below the mesh conveyor belt, stably adsorbing the fiber web onto the surface of the mesh conveyor belt. This effectively prevents problems such as drifting, edge flipping, wrinkling, or stretching deformation of the fiber web during conveying due to workshop airflow disturbances, equipment vibration, and static electricity. Simultaneously, the honeycomb holes in the inner wall of the air duct ensure that the negative pressure is evenly distributed in the width direction, avoiding concentrated or insufficient suction. This invention places the humidification mechanism upstream of the adsorption mechanism. When the humidification mechanism sprays moisture onto the fiber web from above, the adsorption mechanism below the fiber web generates a downward airflow, guiding the water mist more smoothly through the fiber web pores, making the wetting more uniform and deeper. At the same time, it immediately absorbs excess water mist and lint, avoiding equipment contamination or affecting adjacent workstations, achieving a synergistic effect of wetting and adsorption. Furthermore, this invention, through adsorption... A retractable collection box is installed at one end of the air duct, and a filter plate is installed inside the collection box. Dust, lint, and hair in the airflow are intercepted and deposited by the filter plate as they pass through the collection box. The purified air is then discharged by a suction fan. When the debris in the collection box accumulates to a certain level, the operator can easily pull it out for cleaning, maintaining the cleanliness of the equipment and workshop environment while reducing the impact of flying lint on the operator's health. Furthermore, this invention connects the electric push rod of the pressing mechanism to the main control system. The control system automatically adjusts the extension and retraction of the electric push rod according to the conveyor belt speed. When the conveyor speed increases, the pressing roller presses down, increasing the pressing pressure; when the conveyor speed decreases, the pressing roller rises, decreasing the pressing pressure. This achieves adaptive adjustment of pressing pressure in conjunction with conveyor speed, enabling the pressing mechanism to adapt to different weights and speeds, avoiding the problems of insufficient or excessive pressing in traditional fixed pressing mechanisms.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Example 1

[0040] like Figures 1 to 16The device shown is a uniform carding and web-laying apparatus for polyester PET woven fabric, comprising a first support frame 1, a carding machine 2, a second support frame 3, a web-laying machine 4, and a web conveyor belt 6. The carding machine 2 is located on one side of the first support frame 1 to card the opened and mixed PET short fibers to form a uniform fiber web. The second support frame 3 is located on the other side, and the web-laying machine 4 is located on the surface of the second support frame 3. The web-laying machine 4 is used to cross-fold and lay the carded fiber web to form a multi-layer fiber web with a certain thickness and width. The surface of the first support frame 1 is provided with a moving mechanism 5 for moving the web conveyor belt 6. The moving mechanism 5 drives the web conveyor belt 6 to move and conveys the fiber web output from the carding machine 2 from the carding machine output end to the web-laying machine input end. The beginning and end of the web conveyor belt 6 are provided with pressing mechanisms 7 for flattening the fiber web. The pressing mechanisms 7 apply uniform pressure to the fiber web when it enters and leaves the web conveyor belt 6, flattening the loose fibers. The web is flattened and interlayer air is discharged to prevent the web from floating or flipping. The surface of the first support frame 1 is provided with a moistening mechanism 8 for spraying water mist onto the surface of the web to eliminate static electricity. This sprays micron-level water mist onto the surface of the web, increases the moisture regain of the PET fibers, reduces surface resistance, thereby eliminating static electricity and reducing repulsion and adsorption between fibers. The surface of the first support frame 1 is provided with an adsorption mechanism 9 for applying negative pressure to the web on the web conveyor belt 6. This applies negative pressure to the web on the web conveyor belt 6, stably adsorbing the web onto the surface of the web conveyor belt 6, preventing the web from drifting or wrinkling due to airflow disturbance during transmission. The surface of the web laying machine 4 is provided with a web laying mechanism 10, which receives the web output from the end of the web conveyor belt 6 and lays it evenly on the working surface of the web laying machine 4. The surface of the second support frame 3 is provided with a driving mechanism 11, which drives the web laying mechanism 10 to reciprocate, realizing the cross-folding and stacking of the web.

[0041] In a preferred embodiment, the mesh conveyor belt 6 is a mesh structure made of antistatic material with a mesh aperture of 0.5mm-2.0mm. The mesh conveyor belt 6 is made of polyester material with added antistatic agents, possessing good antistatic and breathable properties. The mesh aperture of the mesh conveyor belt 6 is selected according to production needs. When processing finer fibers such as 1.5D, a smaller aperture of 0.5mm to 1.0mm is used to prevent fibers from falling out of the mesh; when processing coarser fibers such as 3D to 6D, a larger aperture of 1.5mm to 2.0mm is used to improve breathability and negative pressure adsorption effect. A third conveyor belt 12 is provided at the bottom of the web laying machine 4, which is used to transport the laid-up fiber web from the output end of the web laying machine 4 to the next process.

[0042] In a preferred embodiment, the moving mechanism 5 includes a first connecting block 501, a fixed rod 502, and a moving roller 503. Multiple sets of first connecting blocks 501 are provided on the surface of the first support frame 1. A fixed rod 502 is rotatably connected between two sets of first connecting blocks 501. A moving roller 503 is fixedly connected to the surface of the fixed rod 502. The moving roller 503 cooperates with the mesh conveyor belt 6. One set of fixed rods 502 serves as the driving roller, driven by a drive motor via a chain or belt transmission. The remaining fixed rods 502 serve as driven rollers, rotating as the mesh conveyor belt 6 moves. Supported and driven by multiple sets of moving rollers 503, the mesh conveyor belt 6 can smoothly carry the fiber web from the output end of the carding machine 2 to the input end of the web laying machine 4.

[0043] In a preferred embodiment, the cotton pressing mechanism 7 includes a fixed sleeve 701, a first sliding groove 702, a first slider 703, a first bearing 704, an electric push rod 705, and a cotton pressing roller 706. The first support frame 1 has two sets of fixed sleeves 701 at its starting end and end, respectively. The fixed sleeve 701 has a first sliding groove 702 inside. The first slider 703 is slidably connected to the inner wall of the first sliding groove 702. The first bearing 704 is fixedly connected to the surface of the first slider 703. The electric push rod 705 is fixedly connected to the surface of the fixed sleeve 701. One end of the electric push rod 705 is fixedly connected to the first bearing 704. The cotton pressing roller 706 is rotatably connected between the two sets of first bearings 704. When the telescopic end of the electric push rod 705 extends, it pushes the first bearing 704 and the first slider 703 to slide downward along the first sliding groove 702. The cotton pressing roller 706 moves downward accordingly, and the distance between the cotton pressing roller 706 and the mesh curtain conveyor belt 6 decreases, increasing the cotton pressing pressure. When the telescopic end of the electric push rod 705 retracts, it pulls the first bearing 704 and the first slider 703 to slide upwards along the first slide groove 702. The pressing roller 706 moves upwards accordingly, increasing the distance between the pressing roller 706 and the mesh conveyor belt 6, thus reducing the pressing pressure. The electric push rod 705 is connected to the device's main control system. The control system automatically adjusts the telescopic amount of the electric push rod 705 according to the conveying speed of the mesh conveyor belt 6. Specifically, when the conveying speed increases, the control system outputs a control signal to increase the extension of the electric push rod 705, causing the pressing roller 706 to press down and increase the pressing pressure to cope with the greater airflow disturbance during high-speed conveying. When the conveying speed decreases, the control system outputs a control signal to retract the electric push rod 705, causing the pressing roller 706 to rise and reduce the pressing pressure to avoid over-compacting the fiber web. This adaptive adjustment mechanism linking pressure and speed allows the pressing mechanism 7 to adapt to production needs of different weights and speeds.

[0044] In a preferred embodiment, the cotton-lubricating mechanism 8 includes a fixed frame 801, a support rod 802, a connecting sleeve 803, a first pulley 804, a first belt 805, a second pulley 806, a water outlet 807, a water pipe 808, a nozzle 809, an air pipe 810, and an air hole 811. The fixed frame 801 is fixedly connected to the surface of the first support frame 1, and the support rod 802 is fixedly connected inside the fixed frame 801. The connecting sleeve 803 is rotatably connected to the surface of the support rod 802, and one end of the connecting sleeve 803 is rotatably connected to the fixed frame 801. A first pulley 804 is fixedly connected to the surface of the 03. A first belt 805 is provided on the surface of the first pulley 804. A second pulley 806 is located inside the first belt 805. The second pulley 806 is fixedly connected to the surface of one set of fixed rods 502. When the fixed rods 502 of the moving mechanism 5 rotate, they drive the second pulley 806 to rotate synchronously. The second pulley 806 drives the first pulley 804 to rotate via the first belt 805. The first pulley 804 then drives the connecting sleeve 803 to rotate synchronously around the support rod 802. Through this transmission chain, the rotational speed of the connecting sleeve 803 of the cotton-lubricating mechanism 8 maintains a fixed speed ratio with the moving speed of the mesh curtain conveyor belt 6, achieving mechanical linkage between the cotton-lubricating mechanism and the mesh curtain conveyor belt.

[0045] In a preferred embodiment, the connecting sleeve 803 has multiple sets of water outlet holes 807 on its surface, arranged in alternating groups along the circumference of the connecting sleeve 803. The support rod 802 has a water pipe 808 inside, with multiple sets of nozzles 809 on its surface. The support rod 802 also has an air pipe 810 inside, with multiple sets of air holes 811 inside one end of each nozzle 809. The air pipe 810 cooperates with the air holes 811. The connecting sleeve 803 rotates continuously under the drive of the fixing rod 502. When the connecting sleeve 803 rotates until the A set of water outlet holes 807 are aligned with the nozzles 809, the A set of nozzles 809 sprays water mist to humidify the fiber web. At this time, the B set of water outlet holes 807 are offset from the nozzles 809, and the B set of nozzles is closed. When the connecting sleeve 803 continues to rotate until the B set of water outlet holes 807 are aligned with the nozzles 809, the B set of nozzles 809 sprays water mist, and the A set of nozzles remains closed. This cyclical alternation allows multiple sets of nozzles to work alternately, with two sets of nozzles not operating simultaneously. The advantages of this alternating spray design are: First, it effectively avoids the problem of adjacent spray cones colliding and merging into large bubbles or droplets when spraying simultaneously with multiple nozzles in traditional methods, ensuring that each droplet can fly independently and evenly onto the fiber surface, significantly improving the uniformity of spraying; Second, when a set of nozzles is in a resting state, no liquid flows through the nozzle orifice. At this time, the air pipe 810 sprays compressed air through the air hole 811, using auxiliary airflow to dry the nozzle orifice, removing residual liquid and attached lint, greatly reducing the clogging problem caused by lint adhesion.

[0046] In a preferred embodiment, the adsorption mechanism 9 includes a support block 901, a bellows 902, an air inlet 903, an air suction pipe 904, a second connecting block 905, a blower 906, an air duct 907, honeycomb holes 908, a groove 909, a collection box 910, a handle 911, and a filter plate 912. Multiple sets of support blocks 901 are fixedly connected to the surface of the first support frame 1, and bellows 902 are provided between the multiple sets of support blocks 901. An air inlet 903 is provided on one side of the bellows 902. One end of the air intake 903 is equipped with an air intake pipe 904, and a second connecting block 905 is provided on one side of the first support frame 1. An air intake fan 906 is located inside the second connecting block 905, with one end of the fan fixedly connected to the air intake pipe 904. An air duct 907 is opened inside the air box 902, and multiple sets of honeycomb holes 908 are formed on the inner wall of the air duct 907. After the air intake fan 906 is started, it draws air from the air duct 907 through the air intake pipe 904, creating a negative pressure inside the air duct 907. This negative pressure is evenly distributed through the honeycomb holes 908 on the inner wall of the air duct 907 and then acts on the fiber mesh on the mesh conveyor belt 6 through the air intake 903. Because the mesh conveyor belt 6 has a mesh structure, the negative pressure can penetrate the mesh openings of the mesh conveyor belt 6, generating a uniform adsorption force on the fiber mesh and stably adsorbing the fiber mesh onto the surface of the mesh conveyor belt 6. The honeycomb holes 908 ensure that the negative pressure in the air duct 907 is evenly distributed in the width direction, avoiding areas of concentrated or insufficient suction. At the same time, when the humidifying mechanism sprays humidification onto the fiber web from above, the negative pressure suction air duct located below the fiber web (below the mesh curtain) will generate a downward airflow, which will guide the water mist to pass more smoothly through the pores of the fiber web, making the wetting more even and deeper. At the same time, excess water mist and lint will be sucked away in time to prevent them from contaminating the equipment or affecting adjacent workstations.

[0047] In a preferred embodiment, a groove 909 is provided at one end of the suction pipe 904, and a collection box 910 is slidably connected to the inner wall of the groove 909. A handle 911 is fixedly connected to one end of the collection box 910. A filter plate 912 is provided inside the collection box 910. When the suction fan 906 is running, airflow enters the air duct 907 from the suction port 903 and flows to the suction fan 906 through the suction pipe 904. As the airflow flows through the collection box 910, dust, lint, and hair in the airflow are intercepted by the filter plate 912 and deposited inside the collection box 910. The purified air is discharged by the suction fan 906. When the debris in the collection box 910 accumulates to a certain level, the operator holds the handle 911 to pull the collection box 910 out of the groove 909, cleans the debris on the filter plate 912, and then pushes the collection box 910 back into the groove 909 for continued use.

A second drive motor 1102 is installed inside one end of the first drive motor 1102. A first connecting rod 1103 is fixedly connected to one end of the second drive motor 1102.

A second rotating rod 1111 is rotatably connected to the surface of the fixing block 1110. One end of the second rotating rod 1111 is fixedly connected to a fixing... Two sets of T-blocks 1113 are fixedly connected to one side of the plate 1112 and the connecting frame 1002. The T-blocks 1113 are slidably connected to the fixed plate 1112. After the second drive motor 1102 is started, it drives the first connecting rod 1103 to rotate. The first connecting rod 1103 drives the third pulley 1105 to rotate. The third pulley 1105 drives the fourth pulley 1107 to rotate through the second belt 1106. The fourth pulley 1107 drives the reciprocating screw 1109 to rotate through the second connecting rod 1108. When the reciprocating screw 1109 rotates, the fixed block 1110 moves back and forth along the axis of the reciprocating screw 1109. The fixed block 1110 drives the fixed plate 1112 to move back and forth through the second rotating rod 1111. The fixed plate 1112 drives the connecting frame 1002 to move back and forth through the T-block 1113, thereby realizing the overall reciprocating motion of the web laying mechanism 10 and completing the cross-folding and laying of the fiber web. At the same time, the first connecting rod 1103 drives the conveyor roller 1104 to rotate. Through the cooperation of the conveyor roller 1104 and the third conveyor belt 12, the laid fiber web is transported to the next process.

[0050] The working process of this application is as follows: After the equipment is started, the PET short fibers after opening and mixing are fed into the carding machine 2. The carding machine 2 opens, mixes and cards the fibers, and cards the loose fiber clumps into a uniform and continuous thin fiber web, which is then output to the mesh curtain conveyor belt 6. The drive motor of the moving mechanism 5 drives the fixed rod 502, which is the active roller, to rotate through a chain or belt. The fixed rod 502 drives the moving roller 503 to drive the mesh curtain conveyor belt 6 to move through friction. The remaining fixed rods 502, which are the driven rollers, rotate with the movement of the mesh curtain conveyor belt 6, so that the mesh curtain conveyor belt 6 smoothly transmits the fiber web from the output end of the carding machine. The fiber web is fed to the input end of the web-laying machine. After entering the starting end of the mesh curtain conveyor belt 6, the electric push rod 705 of the pressing mechanism 7 drives the first bearing 704 and the first slider 703 to slide up and down along the first slide groove 702 according to the control system command. This drives the pressing roller 706 to move up and down to adjust the distance between the pressing roller 706 and the mesh curtain conveyor belt 6. The control system automatically adjusts the extension and retraction of the electric push rod 705 according to the conveying speed of the mesh curtain conveyor belt 6. When the conveying speed increases, the pressing roller 706 presses down to increase the pressing pressure. When the conveying speed decreases, the pressing roller 706 rises to decrease the pressing pressure. This initially presses the fluffy fiber web. The fiber mesh adheres to the surface of the mesh conveyor belt 6, expelling interlayer air. Then, the fiber mesh moves to below the moistening mechanism 8. When the fixed rod 502 of the moving mechanism 5 rotates, it drives the second pulley 806 to rotate synchronously. The second pulley 806 drives the first pulley 804 to rotate via the first belt 805. The first pulley 804 drives the connecting sleeve 803 to rotate synchronously around the support rod 802, maintaining a fixed speed ratio between the rotational speed of the connecting sleeve 803 and the moving speed of the mesh conveyor belt 6. Multiple sets of water outlet holes 807 on the surface of the connecting sleeve 803 alternately align with the nozzles 8 inside the support rod 802 as the connecting sleeve 803 rotates. 09. When the water outlet 807 of group A is aligned with the nozzle 809, the nozzle 809 of group A sprays water mist to humidify the fiber web, while group B is in the closed state. When the connecting sleeve 803 continues to rotate until the water outlet 807 of group B is aligned with the nozzle 809, the nozzle 809 of group B sprays water mist, while group A is in the closed state. The two groups of nozzles alternately and do not open at the same time. At the same time, when a certain group of nozzles is in the resting state, the air pipe 810 sprays compressed air through the air hole 811 to dry the nozzle opening, remove residual liquid and attached lint to prevent blockage. After the water mist is sprayed onto the surface of the fiber web, it increases the moisture regain of PET fibers and reduces surface resistance to eliminate static electricity.The moistened fiber web continues to move to the negative pressure adsorption area of ​​the adsorption mechanism 9. The suction fan 906 draws air from the air duct 907 through the suction pipe 904, creating a negative pressure inside the air duct 907. The negative pressure is evenly distributed through the honeycomb holes 908 on the inner wall of the air duct 907 and then acts on the fiber web on the mesh conveyor belt 6 through the suction port 903. Since the mesh conveyor belt 6 has a mesh structure, the negative pressure can penetrate the mesh holes and generate a uniform adsorption force on the fiber web, stably adsorbing it onto the surface of the mesh conveyor belt 6. At the same time, the downward airflow generated by the adsorption mechanism 9 guides the water mist sprayed by the lint-wetting mechanism 8 to pass more smoothly through the gaps in the fiber web, making the wetting more uniform and deeper, and timely sucking away excess water mist and flying lint. Dust and short fibers in the airflow are also removed. As lint and hair flow through the collection box 910, they are intercepted and deposited by the filter plate 912. The purified air is discharged by the suction fan 906. The fiber web, stabilized by adsorption, is conveyed to the end of the mesh curtain conveyor belt 6. The end pressing mechanism 7 compacts the fiber web a second time in the same way, further expelling interlayer air and eliminating wrinkles, so that the fiber web enters the web laying mechanism 10 in a flat and stable state. After entering the web laying mechanism 10, the fiber web is received by the first conveyor belt 1003 and conveyed forward. The first drive motor 1005 drives the threaded rod 1006 to rotate, and the second slider 1007 slides back and forth along the second slide groove 1004, driving the second bearing 1008 and the second conveyor belt 1009 to move back and forth synchronously to adjust the first drive motor 1003. The spacing between the feeding belt 1003 and the second conveyor belt 1009 allows the fiber web to pass smoothly. Simultaneously, the second drive motor 1102 drives the first connecting rod 1103 to rotate. The first connecting rod 1103 drives the third pulley 1105 to rotate. The third pulley 1105 drives the fourth pulley 1107 to rotate via the second belt 1106. The fourth pulley 1107 drives the reciprocating screw 1109 to rotate via the second connecting rod 1108. The fixing block 1110 reciprocates along the axis of the reciprocating screw 1109. The fixing block 1110 drives the fixing plate 1112 to reciprocate via the second rotating rod 1111. The fixing plate 1112 drives the connecting... The frame 1002 moves back and forth, realizing the overall reciprocating motion of the web-laying mechanism 10, which cross-folds and lays the fiber web on the working surface of the web-laying machine 4. At the same time, the first connecting rod 1103 drives the conveyor roller 1104 to rotate. The conveyor roller 1104, in turn, drives the third conveyor belt 12 to move, transporting the laid-up fiber web from the output end of the web-laying machine 4 to the next process. Thus, after the fiber web is output from the carding machine 2, it successively undergoes initial end pressing, wetting treatment, negative pressure adsorption, end pressing, and cross-folding web laying, finally forming a multi-layer fiber web with uniform thickness and width, completing the entire carding and web-laying process. The above is the working principle of this polyester PET warp and weft woven fabric uniform carding and web-laying device.
