Description

Technical Field

[0001] This invention relates to the field of fabric winding technology, specifically to a winding device and method for using environmentally friendly high-elastic knitted fabrics. Background Technology

[0002] In the textile industry, environmentally friendly high-elastic knitted fabrics are widely used in high-end fields such as sportswear and intimate apparel due to their excellent elasticity, breathability, comfort, and eco-friendly properties. After production, these fabrics need to be wound into neat rolls using a winding device for subsequent storage, transportation, and further processing. However, existing winding devices are prone to edge curling when handling environmentally friendly high-elastic knitted fabrics. Because the fiber structure at the edges of knitted fabrics is loose and has a high elasticity coefficient, the edges are easily folded upwards during winding due to factors such as traction tension and roller friction. This curling not only results in an irregular appearance of the roll but also increases waste in subsequent cutting and sewing processes, seriously affecting product quality. Therefore, there is an urgent need for a winding device and method for environmentally friendly high-elastic knitted fabrics to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a winding device and method for environmentally friendly high-elastic knitted fabrics, which can prevent the fabric from curling at the edges during winding.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0005] An environmentally friendly high-elastic knitted fabric winding device includes a concave winding base, a winding roller and a traction roller installed between the two side walls of the concave winding base, and the fabric is wound up by the winding roller after passing through the traction roller; a pressing component is slidably installed between the two side walls of the concave winding base, and the pressing component is located above the winding roller; an adjustable-angle air jet component is installed between the two side walls of the concave winding base, and the air jet component is located between the winding roller and the traction roller and above the fabric;

[0006] The jet assembly includes an air inlet pipe installed between the two side walls of the concave take-up seat. The air inlet pipe has symmetrical connecting hoses at its two ends. Two connecting hoses are symmetrically connected to strip-shaped jet nozzles facing the sides of the fabric, respectively. The strip-shaped jet nozzles are arranged parallel to the fabric between the take-up roller and the traction roller. A first fixing rod is fixedly installed between the side walls of the concave take-up seat. The first fixing rod is connected to the top of the strip-shaped jet nozzle via a first hinge. A second fixing rod is slidably installed between the side walls of the concave take-up seat. The second fixing rod is hinged to the top of the strip-shaped jet nozzle via a second hinge. The first and second fixing rods are located on opposite sides of the air inlet pipe, with the second fixing rod positioned close to the take-up roller. Both ends of the second fixing rod extend out of the side wall of the concave take-up seat and are connected to the pressing assembly.

[0007] Preferably, the clamping assembly includes a clamping roller, with first sliding blocks installed at both ends of the clamping roller, and second sliding blocks installed at both ends of the second fixing rod, wherein the first sliding blocks and the second sliding blocks are connected by the fixing rod.

[0008] Preferably, the concave winding seat has a first groove and a second groove respectively formed on the two side walls, which cooperate with the first sliding block and the second sliding block.

[0009] Preferably, a limiting shaft is directly installed at the top and bottom of the inner cavity of the first slide groove, and the first slide groove passes through the first sliding block. A first spring is sleeved on the outer wall of the limiting shaft, and the first spring is located above the first sliding block.

[0010] Preferably, one end of the air inlet pipe extends through the side wall of the concave winding seat and is equipped with an air inlet adjustment component;

[0011] The air intake regulating assembly includes an air intake cylinder, with its two ends connected to an air intake pipe and a connecting pipe, respectively. The connecting pipe is connected to an external air source. A first valve plate is fixedly installed between the inner walls of the air intake cylinder. A first air inlet is provided at the lower part of the first valve plate. A second valve plate is rotatably connected to the side of the first valve plate near the connecting pipe. The second valve plate has a second air inlet that cooperates with the first air inlet. The second valve plate extends out of the side wall of the air intake cylinder and is connected to a rotating gear. A rack that cooperates with the rotating gear is installed on the side wall of the second fixed rod.

[0012] Preferably, the second valve plate has symmetrical sealing grooves on its two side walls, and the air inlet includes a first air inlet and a second air inlet, with a sealing ring that cooperates with the sealing groove at one end of each air inlet and the other.

[0013] Preferably, a sealing element for sealing the connecting pipe is provided at one end of the air intake cylinder near the connecting pipe;

[0014] The sealing component includes limiting rods located on both sides of the connecting pipe, and a sealing head is slidably connected between the two limiting rods. A protrusion is installed on the lower part of the end of the sealing head away from the connecting pipe. An arc-shaped protrusion ring is provided on the side of the second valve plate near the sealing head, which cooperates with the protrusion. When the pressing component slides to the top, the arc-shaped protrusion ring abuts against the protrusion and pushes the sealing head into the connecting pipe for sealing.

[0015] Preferably, a second spring is sleeved on the outer wall of the limiting rod, and the second spring is located between the sealing head and the inner end of the air inlet cylinder.

[0016] Preferably, the concave take-up seat has a push switch installed on its side wall that is electrically connected to the drive motor of the take-up roller, and the push switch is located above the pressing assembly. When the pressing assembly touches the push switch, the drive motor stops rotating, and the arc-shaped convex ring abuts against the protrusion.

[0017] The second technical solution provided by this invention is:

[0018] A method for using a winding device for environmentally friendly high-elastic knitted fabrics includes the following steps:

[0019] S1. The environmentally friendly high-elastic knitted fabric is passed through the traction roller and then wound up by the take-up roller.

[0020] S2. During the winding process, the air jet assembly continuously sprays air onto both sides of the fabric to be wound to prevent the fabric from curling due to tension. At the same time, the pressing assembly always presses the winding roller, and the pressing assembly gradually rises as the thickness of the fabric increases during winding, thereby driving the air jet assembly to adjust its angle so that the air jet assembly always remains parallel to the fabric surface, ensuring the air jet effect.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention can spray air onto the edge of the fabric in real time through a strip-shaped jet nozzle during winding, so that the airflow can be blown accurately and evenly to the edge area of ​​the fabric. The airflow pressure smooths and straightens the edge that is about to fold, avoiding the curling phenomenon from the source and ensuring that the edge of the wound fabric roll is neat. Moreover, when the diameter of the fabric roll on the winding roller increases, the pressing component slides upward and drives the second fixing rod to rise synchronously. The second hinge pushes the strip-shaped jet nozzle to rotate around the first hinge, realizing automatic adjustment of the jet angle. It always maintains the optimal angle between the strip-shaped jet nozzle and the edge of the fabric, avoiding the jet direction deviation caused by the change of the fabric roll diameter, ensuring that the airflow continuously and accurately acts on the edge curling area, and stably preventing curling throughout the process.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-7 As shown: Embodiment 1 of the present invention is as follows:

[0035] An environmentally friendly high-elastic knitted fabric winding device includes a concave winding base 1, a winding roller 2 and a traction roller 3 installed between the two side walls of the concave winding base 1, and the fabric is wound up by the winding roller 2 after passing through the traction roller 3; a pressing component 4 is slidably installed between the two side walls of the concave winding base 1, and the pressing component 4 is located above the winding roller 2; an adjustable-angle air jet component 5 is installed between the two side walls of the concave winding base 1, and the air jet component 5 is located between the winding roller 2 and the traction roller 3 and above the fabric.

[0036] The jet assembly 5 includes an air inlet pipe 51 installed between the two side walls of the concave take-up seat 1. The two ends of the air inlet pipe 51 are symmetrically connected to connecting hoses 52. The two connecting hoses 52 are symmetrically connected to strip-shaped jet nozzles 53 facing the two sides of the fabric, and the strip-shaped jet nozzles 53 are arranged parallel to the fabric between the take-up roller 2 and the traction roller 3. A first fixing rod 54 is fixedly installed between the side walls of the concave take-up seat 1. The first fixing rod 54 is connected to the top of the strip-shaped jet nozzle 53 through a first hinge 55. A second fixing rod 56 is slidably installed between the side walls of the concave take-up seat 1. The second fixing rod 56 is hinged to the top of the strip-shaped jet nozzle 53 through a second hinge 57. The first fixing rod 54 and the second fixing rod 56 are located on both sides of the air inlet pipe 51, and the second fixing rod 56 is set close to the take-up roller 2. The two ends of the second fixing rod 56 extend out of the side wall of the concave take-up seat 1 and are connected to the pressing assembly 4.

[0037] In this embodiment, the pressing assembly 4 includes a pressing roller 41, with first sliding blocks 42 installed at both ends of the pressing roller 41, and second sliding blocks 43 installed at both ends of the second fixed rod 56. The first sliding blocks 42 and the second sliding blocks 43 are connected by a fixed rod 44. This linkage structure enables the pressing assembly and the second fixed rod to form a synchronous lifting relationship. That is, when the pressing roller moves upward due to the increase in the diameter of the fabric roll, the first sliding blocks drive the second sliding blocks and the second fixed rod to rise synchronously through the fixed rod, thereby driving the strip-shaped air nozzle to adjust its angle. This synchronous linkage ensures the synergy of the two core functions of pressing to prevent loosening and air jetting to prevent edge curling, avoiding edge curling problems caused by asynchronous actions of the two. The structure is simple and highly reliable.

[0038] In this embodiment, the concave take-up base 1 has a first groove 11 and a second groove 12 on its two side walls that cooperate with the first sliding block 42 and the second sliding block 43. The first groove can prevent the sliding block from shifting laterally during the lifting process, ensuring that the pressure roller is always aligned with the center of the take-up roller, and avoiding uneven tension at the edge of the fabric due to pressure shift. The second groove can ensure that the second fixed rod can lift and lower smoothly, thereby making the angle adjustment of the strip jet nozzle accurate and always aligned with the edge of the fabric, avoiding the jet direction from deviating from the edge area due to sliding shift, and ensuring a stable anti-rolling effect.

[0039] In this embodiment, a limiting shaft 45 is directly installed at the top and bottom of the inner cavity of the first slide groove 11, and the first slide groove 11 passes through the first sliding block 42. A first spring 46 is sleeved on the outer wall of the limiting shaft 45, and the first spring 46 is located above the first sliding block 42. The first spring is sleeved on the limiting shaft and located above the first sliding block. It can provide continuous downward pressure to the first sliding block through elasticity, so that the pressing roller is always tightly attached to the surface of the fabric roll. Even if the diameter of the fabric roll changes, it can maintain a stable pressing force, avoid the fabric from curling due to local loosening, and provide a basic guarantee for the anti-curling function of the air jet assembly.

[0040] In this embodiment, one end of the air inlet pipe 51 extends through the side wall of the concave winding seat 1 and is equipped with an air inlet regulating component 6.

[0041] The air intake regulating assembly 6 includes an air intake cylinder 61. Both ends of the air intake cylinder 61 are connected to an air intake pipe 51 and a connecting pipe 62, respectively. The connecting pipe 62 is connected to an external air source. A first valve plate 63 is fixedly installed on the inner wall of the air intake cylinder 61. A first air inlet 64 is provided at the lower part of the first valve plate 63. A second valve plate 65 is rotatably connected to the side of the first valve plate 63 near the connecting pipe 62. The second valve plate 65 has a second air inlet 66 that cooperates with the first air inlet 64. The second valve plate 65 extends out of the side wall of the air intake cylinder 61 and is connected to a rotating gear 67. A rack 58 that cooperates with the rotating gear 67 is installed on the side wall of the second fixed rod 56. When the fabric roll diameter is small, the second fixed rod drives the rack to move downwards, and the rack drives the rotating gear 67. As the wheel rotates, the overlapping area between the second air inlet of the second valve plate and the first air inlet of the first valve plate increases, and the air intake volume increases. At this time, the fabric edge is prone to curling due to high tension. The increased jet intensity can effectively smooth the fabric edge and prevent curling. When the fabric roll diameter increases, the pressing component drives the second fixed rod to rise, and the rack drives the rotating gear to rotate in the opposite direction, which reduces the overlapping area of ​​the two air inlets and reduces the air intake volume. At this time, the fabric roll has formed a stable structure, and the risk of edge curling is reduced. The reduced jet intensity can avoid excessive airflow damaging the fabric edge and save energy. This adjustment process does not require manual intervention and is achieved entirely through component linkage. It not only ensures the stability of the anti-curling effect at different winding stages, but also improves the automation level of the device and reduces the intensity of manual operation.

[0042] In this embodiment, the second valve plate 65 is symmetrically provided with sealing grooves 68 on its two side walls. The air inlet cylinder 61 includes a first air inlet cylinder and a second air inlet cylinder. Both the first air inlet cylinder and the second air inlet cylinder are provided with sealing rings 69 that cooperate with the sealing grooves 68 at their respective ends. The sealing grooves on both sides of the second valve plate cooperate with the sealing rings of the air inlet cylinder, which can significantly improve the sealing performance of the air inlet cylinder, prevent airflow from leaking from the gap between the second valve plate and the air inlet cylinder, and ensure that the second valve plate can rotate normally.

[0043] In this embodiment, a sealing element for sealing the connecting pipe 62 is provided at one end of the air intake cylinder 61 near the connecting pipe 62;

[0044] The sealing component includes limiting rods 610 located on both sides of the connecting pipe 62. A sealing head 611 is slidably connected between the two limiting rods 610. A protrusion 612 is installed on the lower part of the end of the sealing head 611 away from the connecting pipe 62. An arc-shaped protrusion ring 613 that cooperates with the protrusion 612 is provided on the side of the second valve plate 65 near the sealing head 611 (and the two ends of the protrusion 612 and the arc-shaped protrusion ring 613 are provided with mutually cooperating inclined surfaces to ensure a smooth transition when in contact). When the pressing component 4 slides to the top, the arc-shaped protrusion ring 613 abuts against the protrusion 612 and pushes the sealing head 611 into the connecting pipe 62 for sealing. After winding, the air source can be automatically cut off. That is, when the pressing component slides to the top (the fabric roll reaches the set diameter), the arc-shaped protrusion ring of the second valve plate abuts against the protrusion of the sealing head, pushes the sealing head into the connecting pipe, and cuts off the connection between the external air source and the air inlet pipe. At this point, the strip-shaped jet nozzle stops spraying gas, preventing energy waste caused by the gas source being turned off, and eliminating the need for manual shut-off of the gas source, thus improving ease of operation.

[0045] In this embodiment, a second spring 614 is sleeved on the outer wall of the limiting rod 610, and the second spring 614 is located between the sealing head 611 and the inner end of the air inlet cylinder 61. The second spring can automatically release the seal when the winding is restarted. That is, when the wound fabric roll is removed, the pressing component slides downward, the second valve plate rotates in the opposite direction with the rack, the arc-shaped convex ring separates from the convex block, and the elastic force of the second spring pushes the sealing head to slide away from the connecting pipe, thereby releasing the seal on the connecting pipe.

[0046] In this embodiment, a push switch 7 electrically connected to the drive motor of the take-up roller 2 is installed on the side wall of the concave take-up base 1. The push switch 7 is located above the pressing component 4. When the pressing component 4 touches the push switch 7, the drive motor stops rotating, and the arc-shaped convex ring 613 abuts against the protrusion 612. When the fabric roll reaches the set diameter, the pressing component slides upward to touch the push switch, and the drive motor immediately stops rotating, avoiding over-winding that causes the edge of the fabric roll to be squeezed and deformed. At the same time, when the push switch is triggered, the arc-shaped convex ring abuts against the protrusion, pushing the sealing head to seal the connecting pipe. This synchronous action not only prevents the motor from continuing to rotate and causing damage to the edge of the fabric roll, but also avoids residual airflow from aggravating edge curling. At the same time, it realizes full-process automation without manual intervention, improving production efficiency and product quality stability.

[0047] The specific working process of the winding device in the above embodiment is as follows:

[0048] Initial winding state: There is no fabric on the winding roller 2. The pressing assembly 4 is in the lowest position under the elastic force of the first spring 46, which simultaneously drives the second fixing rod 56 to the low position. At this time, the second air inlet 66 of the second valve plate 65 and the first air inlet 64 of the first valve plate 63 have the largest overlapping area and the largest air intake. The arc-shaped convex ring 613 is separated from the protrusion 612. The sealing head 611 is away from the connecting pipe 62 under the action of the second spring 614, and the connecting pipe 62 is unobstructed. At the same time, the external air source is delivered to the strip jet nozzle 53 through the connecting pipe 62, the air inlet cylinder 61, the air inlet pipe 51, and the connecting hose 52. The two strip jet nozzles 53 spray strong airflow to the two sides of the fabric respectively, providing protection against edge curling for the fabric that is about to enter.

[0049] Winding Start and Anti-Curling Adjustment: The drive motor of the winding roller 2 is started. After being pulled by the traction roller 3, the fabric enters the winding roller 2 and begins to wind. As the diameter of the fabric roll gradually increases, the fabric roll pushes the pressure roller 41 to move upward, causing the first sliding block 42 to slide upward along the limiting shaft 45 in the first groove 11. The first spring 46 is compressed. During the winding process, the strip-shaped air nozzle 53 sprays a strong airflow onto the edge of the fabric in real time, so that the airflow can be blown accurately and evenly to the edge area of ​​the fabric. The airflow pressure smooths and straightens the edge that is about to fold, thus preventing the curling phenomenon from the source.

[0050] Furthermore, the first sliding block 42 drives the second sliding block 43 to slide upward along the second slide groove 12 via the fixed rod 44, simultaneously driving the second fixed rod 56 to rise. The second fixed rod 56 pushes the strip-shaped jet nozzle 53 to rotate around the first hinge 55 via the second hinge 57, so that the strip-shaped jet nozzle 53 always remains parallel to the current fabric edge, ensuring that the airflow accurately acts on the edge area and continuously prevents edge curling. At the same time, the rack 58 on the side wall of the second fixed rod 56 drives the rotating gear 67 to rotate, driving the second valve plate 65 to rotate, so that the overlapping area of ​​the second air inlet 66 and the first air inlet 64 gradually decreases, the air intake volume decreases synchronously, and the jet intensity weakens as the fabric roll diameter increases—ensuring strong airflow to prevent edge curling when the diameter is small, and avoiding strong airflow to damage the fabric when the diameter is large.

[0051] Rewinding completion and automatic shutdown and air cut-off: When the fabric roll diameter reaches the set value, the pressing component 4 rises to the highest position, the first sliding block 42 touches the press switch 7, the press switch 7 stops the motor from rotating, and the winding roller 2 stops winding to prevent the fabric roll from being over-wound and causing edge damage; at the same time, the second valve plate 65 rises and rotates with the rack 58 to a specific position, the arc-shaped protrusion 613 on its side wall abuts against the protrusion 612 of the sealing head 611, pushing the sealing head 611 to slide along the limit rod 610 towards the connecting pipe 62, and the second spring 614 is compressed; when the sealing head 611 is fully inserted into the connecting pipe 62, the connecting pipe 62 is blocked, the air source is cut off, and the strip-shaped air nozzle 53 stops airing.

[0052] Device reset and preparation for next winding: After the fabric roll is removed from the winding roller 2, the clamping assembly 4 slides downward under the force of the first spring 46, the first sliding block 42 separates from the push switch 7, and the drive motor returns to standby mode; at the same time, the second fixing rod 56 descends, the rack 58 drives the rotating gear 67 to rotate in the opposite direction, the second valve plate 65 resets, and the overlapping area of ​​the second air inlet 66 and the first air inlet 64 returns to its maximum; the arc-shaped convex ring 613 separates from the protrusion 612, the sealing head 611 resets under the force of the second spring 614, the connecting pipe 62 is unblocked, the external air source resumes air supply, the strip-shaped air nozzle 53 resumes air supply, and the device returns to the initial ready-to-wind-up state, waiting for the next roll of fabric to be wound, completing the anti-rolling edge preparation automatically throughout the process.
